Frame structure of foldable tent

The present invention relates to a frame structure of a foldable tent.

The foldable tent is convenient for transportation and storage because the tent, which is a large structure, can be folded to reduce the volume. In addition, some foldable tents have a structure that makes them easy to set up and withdraw. As described above, the foldable tent has many excellent advantages.

The foldable tent, which has a structure that can be easily set up and withdrawn, cannot secure sufficient strength due to its structure, and has a problem that the frame cannot withstand and deforms when the tent receives a strong wind. A typical technique for solving this problem is described in Patent Document 1. This technology is a foldable tent in which the side link member does not deform even when a crosswind acts and the side surface of the curtain can be fixed to the frame member parallel to the ground. This is strengthened by a cross material that makes the frame hung between the struts on the upper part of the struts and the lower frame hung parallel to the lower part of the frame slidable.

<p> There is a need for a foldable tent that can be easily set up and withdrawn. The conventional structure has a problem that the strength is not sufficient with respect to the wind and the cloth material formed so as to be stretchable between the columns is easily deformed. In the technique described in Patent Document 1, the cross material reinforced on the same surface as the surface connecting the columns increases the strength in the direction parallel to the link frame hung between the columns.</p><p> Due to strong winds, a strong force is often applied to the crossing link members that are stretchable between the columns even from the vertical direction, and this method is insufficient to prevent the crossing link members from being deformed.</p><p> An object of the present invention is that setup and withdrawal work can be easily performed, and deformation of a frame such as a crossing link member configured to be stretchable between columns can be prevented even in a situation where a strong force is applied such as in a strong wind. It is to provide a frame structure for a foldable tent.</p>

<p> In the present invention, at least three or more columns arranged in the circumferential direction are connected to one end of each column so as to be angularly displaceable, and the end connected to each column and the end opposite to the end can be displaced to each other. It is characterized by including a plurality of roof bars connected to the roof bar, a connecting means for connecting two columns adjacent to each other in the circumferential direction at the upper part of each column, and a support bar for connecting each roof bar and the connecting means. It is a frame structure of a foldable tent.</p><p> According to the present invention, even when a strong force is applied to the tent in a strong wind or the like, the force applied to the connecting means is supported by the support bar that connects the connecting means and the roof bar, and is distributed to various parts of the frame of the tent. To. Further, for example, it can be expected that the support bar bends to absorb energy due to a strong wind or the like. Therefore, the connecting means is not deformed.</p><p> Further, the present invention is characterized in that each support bar is displaceably connected in the axial direction of the roof bar.</p><p> According to the present invention, since the roof bar is displaceably connected in the axial direction, the support bar is appropriately displaced in the axial direction at the time of folding, so that the support bar can be folded without being removed. Never forget to put on or take off the support bar. Furthermore, for example, when the support bar is connected in a detachable manner rather than being displaceable in the axial direction of the roof bar, the frame is not deformed when folded due to forgetting to remove the support bar, and the support bar that is forgotten to remove causes the tent to be deformed. The tent will not be damaged.</p><p> Further, the present invention has a structure in which the connecting means is realized by a pantograph, and two link members are connected to the support column at different positions at both ends, and at least one of the two link members is connected to the support column by a connecting tool. It is displaceably connected in the axial direction, and the connector fits into the positioning hole formed in the support column when the link member is placed at a predetermined position of the support column, and from the fitting position and the positioning hole that fit into the positioning hole. A positioning member that can be displaced to the retracted retracted position, a spring member that gives the positioning member a force in the direction toward the column, an allowable state that allows the positioning member to be displaced to the fitting position, and a displacement to the fitting position. It is characterized by including an operation member capable of operating a holding state in which the vehicle is held in a retracted position.</p><p> According to the present invention, by operating the operating member, the positioning member is displaced to the fitting position, and the spring member applies a force in the direction toward the support to the positioning member to allow the displacement to the fitting position. Can be. When the allowable state is reached, the positioning member can be fitted into the positioning hole formed in the support column when the link member is arranged at a predetermined position on the support column. Therefore, at least one of the two link members of the strut and the connecting means can be fixed at a predetermined position of the strut, so that the deployment of the foldable tent can be completed. By operating the operating member, the positioning member can be displaced to the retracted position to bring the positioning member into a holding state. Therefore, since the positioning member can be held in the holding state by operating the operating member, it is not necessary to keep holding the positioning member manually. Therefore, it is easy to set up or withdraw. In addition, the positioning member is less likely to damage the support column.</p><p> Further, in the present invention, the strut is a stretchable strut, which is realized by an upper strut member and a lower strut member, and the lower strut member is displaceably connected in the axial direction of the strut by a connecting tool under the upper strut member. The connector fits into the positioning hole formed in the lower strut when the upper strut member is arranged at a predetermined position of the lower strut, and fits into the positioning hole and retracts from the positioning hole. A positioning member that can be freely displaced, a spring member that gives a force to the positioning member in the direction toward the column, an allowable state that allows the positioning member to be displaced to the fitting position, and a control that controls the displacement to the fitting position It is characterized by including an operating member capable of operating a holding state held in a retracted position.</p><p> According to the present invention, by operating the operating member, the positioning member is displaced to the fitting position, and the spring member applies a force in the direction toward the support to the positioning member to allow the displacement to the fitting position. Can be. When the allowable state is reached, the positioning member can be fitted into the positioning hole formed in the lower strut member when the upper strut member is arranged at a predetermined position on the lower strut member. Therefore, the upper strut member can be fixed at a predetermined position of the lower strut member by the connecting tool under the upper strut member. Therefore, the length of the column can be expanded and contracted. Further, by operating the operating member, the positioning member can be displaced to the retracted position to bring the positioning member into a holding state.

FIG. 1 is a perspective view showing a frame structure 1 of a foldable tent according to the present embodiment. FIG. 2 is an enlarged view showing a part of the frame structure 1 of the foldable tent of the present embodiment. In this embodiment, four columns 11, four roof bars 19, connecting means 30 for connecting the columns 11 and the columns 11, support bars 35 and 37 for connecting the connecting means 30 and the roof bar 19, and the like. It is a frame structure 1 of a foldable tent including a support bar 39 between columns and roof bars connecting a column 11 and a roof bar 19.

The material of the frame member such as the support column 11, the roof bar 19, the connecting means 30, the support bars 35, 37, and the support bar between the support bars is not particularly limited, but iron, aluminum, or an alloy thereof can be preferably used. .. It is preferable to use a hollow quadrangular prism for weight reduction. By attaching a member made of resin formed in a semi-cylindrical shape to the tip portion of the frame member, it is possible to prevent injury to a person who handles the foldable tent.

Four columns 11 are erected side by side at the corners forming a square. The present invention does not necessarily have to be the corners forming a square, and the columns 11 may be provided at the corners of the rectangle. Further, it is not always necessary to provide the support at the corner, and the support 11 may be provided within the line segment connecting the support 11 and the support 11. The present invention can be applied as long as there are three or more columns 11. For example, if there are five columns 11, the columns 11 can be erected at the corners that form a regular pentagon, and if there are six columns 11, the columns 11 can be erected at the corners that form a regular hexagon.

The roof bar 19 is angularly displaceably connected to one end of each column 11, and the end opposite to the end connected to each column 11 is angularly displaceably connected to each other. The roof bar 19 is composed of two bars of a first roof member 17 and a second roof member 18 having substantially the same length, and the ends of the two bars are stoppers which are hinge structure connectors. Connected by 31. FIG. 3 is a perspective view showing the roof bar 19 when folded. With such a configuration, since the middle portion of the roof bar 19 is bent at the time of folding, even a long roof bar 19 can be folded. At the same time, the hinge-structured connector also serves to stop the movement of the support bar 30 that connects the connecting means 30 and the roof bar 19. Therefore, the number of parts can be reduced, resulting in cost reduction. One end of the roof bar 19 is angularly displacedly connected to one end of the support column 11 by a frame connector 21 which is a hinge-structured connector. The end opposite to the end connected to the column 11 is connected to each roof bar 19 by a roof bar connector 20 having a hinge structure that is angularly displaceably connected. The roof bar connector 20 also serves to fix the center of the tent awning 47 at the same time. A tent cap member 119 for fixing the tent is provided on the roof bar connector 20 and can be folded with the tent attached, so that the tent is not lost.

The support bar 39 between the column roof bars connects the upper part of the column 11 and the portion of the roof bar 19 at a distance of about 1/4 of the entire roof bar 19 from the column side. One end of the support bar 39 between the strut roof bars is hinged to the strut slider member 15 provided on the upper part of the strut 11 so as to be freely displaceable in the axial direction of the strut. The other end of the support bar 39 between the column roof bars is connected to the roof stopper 41, which is a portion at a distance of about 4, with a hinge. This structure can increase the strength of the columns 11 and the roof bar 19.

The connecting means 30 flexibly connects two columns 11 adjacent to each other in the circumferential direction at the upper part of each column 11. The connecting means 30 is flexibly realized by a pantograph including a link member that crosses in an X shape. The third link member 25 and the fourth link member form an X-shaped cross member. The fifth link member 27 and the sixth link member 28 form an X-shaped cross member. The first link member 23 and the second link member 24 form an X-shaped cross member. In the present embodiment, the connecting means 30 for connecting the columns 11 is realized by a XXX type pantograph in which these are combined. The link member that crosses the X shape has high strength against the force acting in parallel between the columns 11. The lateral upper end of the link member crossing in an X shape is connected to the upper end of the support column 11, and the lateral lower end of the link member is connected to the support column 11 by the support column slider member 15 which is a connecting tool above the support column 11. It is connected so that it can be displaced in the axial direction. Therefore, since each X-shaped cross member approaches the I-shaped when folded, the distance between the columns 11 is reduced, so that the X-shaped cross member can be stored compactly.

More specifically, the third link member 25 and the fourth link member 26 intersect at an intermediate portion, and the intersecting portions are connected by pins to form an X-shaped cross member. One end of the third link member 25 is connected to the upper end of the support column 11 by a frame connector 21, and one end of the fourth link member 26 is detachably attached to the upper end of the support column 11 in the axial direction. It is connected by a slider member 15. The fifth link member 27 and the sixth link member 28 intersect at an intermediate portion, and the intersecting portions are connected by pins to form an X-shaped cross member. The other end of the fourth link member 26 is connected to one end of the sixth link member 27 with a pin, and the support bar connecting member 43 is attached. The other end of the third link member 25 is pinned to one end of the fifth link member 27. The first link member 23 and the second link member 24 intersect at an intermediate portion, and the intersecting portions are connected by pins to form an X-shaped cross member. The other end of the sixth link member 28 and one end of the first link member 23 are connected by a pin, and the support bar connecting member 43 is attached. The other end of the fifth link member 27 is pinned to one end of the second link member 24. The other end of the first link member 23 is connected to the upper end of another column 11 adjacent to the column 11 by a frame connector 21, and the other end of the second link member 24 is adjacent to the column 11. It is connected by a slider member 15 attached so as to be displaced in the axial direction of another matching column 11.

FIG. 4 is an enlarged view showing the support bar connecting member 43. FIG. 4 is an enlarged view showing the roof portion slider member 33. FIG. 5 is a top view of the roof portion slider member 33 of the unfolded foldable tent as viewed from above. In the present embodiment, the middle portion of the roof bar 19 and the upper end portion of the rhombus in the middle of the XXX type pantograph connected between the columns 11 are connected by the support bars 35 and 37. One end of the support bars 35 and 37 and the upper end of the two link members are connected to the upper end of the diamond shape in this pantograph. Therefore, the force applied to the XXX type pantograph which is the connecting means 30 due to a strong wind or the like can be supported and dispersed in various directions, so that the XXX type pantograph which is the connecting means 30 is not deformed. Further, since the force applied to the roof bar 19 can be dispersed in various places, the roof bar 19 can be prevented from being deformed. Ball studs 90 having ball heads 91 are provided at both ends of the support bars 35 and 37. Two link members are connected to the upper part of the rhombus in the middle of the XXX type pantograph, which is the connecting means 30, and are rotatable around an axis consisting of bolts 81 and nuts 83 that are connected via washers 85, and ball studs 90. The socket portion 87 that receives the ball head 91 of the above is parallel to the plane formed by the link member that crosses the X shape, and has an opening in the direction parallel to the link member that crosses the one X shape. Is installed.

In the present embodiment, the other end of the support bars 35 and 37 is connected to the roof slider member 33 which moves freely in the axial direction of the roof bar 19. The roof slider member 33 on the roof bar 19 has a ball stud 90. A socket portion 87 for receiving the ball head 91 is formed. The roof portion slider member 33 receives two support bars, a first support bar 35 and a second support bar 37, facing each other. Further, the roof portion slider member 33 is restricted from moving to a portion of the roof bar 19 other than between the roof stopper 41 and the stopper 31 by the roof stopper 41 and the stopper 31 in the axial direction of the roof bar 19. Both ends of the support bars 35 and 37 are connected by a ball joint including the ball stud 90 and the socket part of the above-mentioned shape, and the connecting part to the roof bar 19 is slidable, so that it can be folded and unfolded. Becomes easier. This structure makes it easy to fold and increase the strength of the frame structure. In the present invention, as a method of connecting the support bars 35 and 37 and the roof bar 19, one end or both ends can be connected by installing a ring for receiving the hook on the roof bar 19 by using a so-called hook. When both ends of the support bars 35 and 37 are connected to the roof bar 19 with hooks, the support bars 35 and 37 can be detached.

FIG. 6 is a perspective view showing a connected state of the link member of the foldable tent in the folded state and the support bars 35 and 37. FIG. 7 is a diagram showing a support bar connecting member 43. FIG. 7 (1) is a top view of the support bar connecting member 43 as viewed from above. FIG. 7 (2) is a front view of the support bar connecting member 43 as viewed from the front. FIG. 8 is a diagram showing a connected state of the roof bar 19 and the support bars 35 and 37 of the foldable tent in the folded state. FIG. 9 is a side view showing the support bars 35 and 37.

The support bar connecting member 43 has a socket portion 87 at one end of the base portion 111, and a link member mounting portion 115 at the other end of the base portion 111. The socket portion 113 of the support bar connecting member 43 has a substantially cylindrical shape, and the upper side surface has a wide width from the end of the circle to the side surface of the cylinder from the position of 1/4 of the diameter of the circle on the diameter of the circle on the upper surface of the cylinder. Has a narrow groove. A ball stud 90 having a ball-bearing portion 91 and a shaft portion 89 attached to both ends of the support bars 35 and 37 preferably fits into this groove when folded. Specifically, the diameter L1 of the cylinder of the socket portion 87 is 2.7 cm, the length L7 in the axial direction of the cylinder is 2.2 cm, the width L3 of the groove on the upper surface of the cylinder is 1.4 cm, and the circle. The length L2 of the groove in the radial direction of the circle of the columnar surface is 1.9 cm, the width L3 of the groove at the upper part of the side surface of the cylinder is 1.4 cm, and the width L9 of the groove at the lower part of the side surface of the cylinder is 1.0 cm. The length L4 of the wide groove on the side surface of the cylinder in the direction of the cylinder axis is 1.0 cm, and the length L5 of the narrow groove on the side surface of the cylinder in the direction of the cylinder axis is 0.7 cm. The length L6 in the longitudinal direction of the base portion 111 is 3.8 cm, the width L10 perpendicular to the longitudinal direction of the base portion 111 is 2.7 cm, and the base portion 111 is erected perpendicularly to the other end of the wide surface of the base portion 111. The length L8 in the direction perpendicular to the wide surface of the base portion 111 of the link member mounting portion 115 is 1.9 cm.

The roof portion slider member 33 also includes the socket portion 87. There is a groove on the upper surface of the socket portion 87 of the second roof member 18 in the cylindrical direction, parallel to the longitudinal direction of the roof bar 19, on the diameter of the circle on the upper surface of the cylinder, and having an opening toward the support column. This groove is connected to the side surface of the cylinder, and the lower part of the groove on the side surface of the cylinder is narrowed. The specific dimensions of the socket portion 87 of the roof portion slider member 33 are the same as the dimensions of the socket portion 87 of the support bar connecting member 43.

Ball studs 90 are provided at both ends of the support bars 35 and 37. The extension line of the central axis of the shaft portion 89 of the pole stud 90 and the center of the ball-bearing portion 91 are misaligned. The diameter of the sphere of the sphere-bearing portion 91 in the present embodiment is 1.5 cm. Specifically, in the present embodiment, the distance L11 that vertically connects the central axis of the shaft portion 89 of the ball stud 90 and the center of the ball of the ball-bearing portion 91 is 0.7 cm. Further, the deviations at both ends are offset in opposite directions. Due to this deviation, the positions of the ends of the support bars 35 and 37, the support bar connecting member 43, and the roof portion slider member 33 are improved, and it is difficult for them to collide with other frames when folded.

Since the lower portion of the side surface of the cylinder of the socket portion 87 has a width suitable for accommodating the shaft portion 89 of the ball stud 90, it is possible to reduce the decrease in the strength of the socket portion 87 due to the groove opened in the socket portion.

Since the link member attachment portion 115 of the support bar connecting member 43 is rotatably attached to the link member of the connecting portion 30, folding can be made smooth. Further, although the adjacent support bar connecting members 43 are close to each other when folded, they are rotatable and are not destroyed even if they collide with each other.

Further, the socket portion 87 of the support bar connecting member 43 and the link member mounting portion 115 are separated from each other, and the opening direction of the groove portion of the socket portion 87 of the support bar connecting member 43 is perpendicular to the longitudinal direction of the base portion 111. It is oriented in the axial direction to connect to the column, and the opening direction of the groove of the socket portion 87 of the roof portion slider member 33 is parallel to the longitudinal direction of the roof bar 19 and is on the diameter of the circle on the upper surface of the cylinder and in the column direction. It faces, and the extension of the axis of the shaft portion 89 of the ball stud 90 at both ends of the support bars 35 and 37 and the center of the ball-bearing portion 91 are offset from each other at both ends. The support bars 35,37 are perpendicular to the axis of the support bars 35,37 when folded, and the width direction of the long length is almost parallel to the roof bar diagonally between the columns. It can be stored compactly without colliding with other frame members.

The opening direction of the groove portion of the socket portion 87 of the support bar connecting member 43 is perpendicular to the longitudinal direction of the base portion and faces the direction connected to the support column in the axial direction of the link member, and the groove portion of the socket portion 87 of the roof portion slider member 33. Since the opening direction of the roof bar is parallel to the longitudinal direction of the roof bar, is on the diameter of the circle on the upper surface of the cylinder, and faces the support column direction, the support bars 35 and 37 are placed in a part different from the grooved part at the time of deployment. Since it supports and receives strong force such as in strong winds, the strength of the socket portion 87 can be fully exhibited.

The support bars 35,37 are perpendicular to the axis of the support bars 35,37 when folded, and the width direction of the long length is substantially parallel to the roof bar 19 on the diagonal line between the columns, and the support bars 35,37. At the end of the, the back surface side of the facing surface connected to the roof bar 19 becomes a surface facing the support bar connecting member 43. Because of this arrangement, the opening direction of the groove portion of each socket portion 87 is appropriate, so that the support bars 35 and 37 do not rotate about the central axis without receiving a force in the twisting direction at the time of folding.

FIG. 10 is a diagram showing a state in which the pin portion of the support column telescopic portion 13 of the foldable tent of the present embodiment is in the holding state. FIG. 10 (1) shows a front view of the support column telescopic portion 13. FIG. 10 (2) shows a cross-sectional view of the column telescopic portion 13 as seen from AA in FIG. 10 (1). FIG. 11 is a diagram showing a state in which the pin portion of the support column telescopic portion 13 of the foldable tent of the present embodiment is in a fitted state with a hole formed in the support column. FIG. 11 (1) shows a front view of the support column telescopic portion 13. FIG. 11 (2) shows a cross-sectional view of the support column telescopic portion 13 as seen from the BB of FIG. 11 (1). The support column 11 is an extendable support column 11, which is realized by an upper support column member 10 and a lower support column member 8, and the lower support column member 8 is a support column 11 by a support column expansion / contraction portion 13 which is a connecting tool under the upper support column member 10. It is connected so that it can be displaced in the axial direction of. The lower end portion 12 of the support column is installed at the lower end of the lower support column member 8. The lower end portion 12 of the support column has a role of restricting the movement of the lower support column member 8 when the support column 11 contracts, and two holes for piling are provided on the surface in contact with the ground, so that the foldable tent is fixed to the ground. Play a role in The strut telescopic portion 13 which is a connecting tool includes a positioning member, a spring member, and an operating member.

The positioning member is freely displaceable between a fitting position where it fits into the positioning hole and a retracted position retracted from the positioning hole, and when the upper strut member 10 is arranged at a predetermined position of the lower strut member 8, it depends on the spring member. It fits into the positioning hole 71 formed in the lower strut member 8 by the force in the direction toward the strut. Specifically, the positioning member is realized by a pin 63 made of a hard metal such as iron. A spring member that gives a force to the positioning member in the direction toward the support column 11 is realized by a coil spring 65 or the like. The operating member makes it possible to operate the allowable state in which the positioning member such as the pin 63 is allowed to be displaced to the fitting position and the holding state in which the displacement to the fitting position is suppressed and held in the retracted position. Specifically, the operating member is realized by the ring 61. When a deep groove and a shallow groove are dug in the pin cylinder 67 and the ring 61 is fitted in the deep groove 95, the pin 63 is given a force in the direction toward the column by the coil spring to allow displacement to the fitting position. When the ring 61 fits into the shallow groove 97, the pin 63 is held in the retracted position.

When the allowable state is reached, the positioning member can be fitted into the positioning hole formed in the lower strut member 8 when the upper strut member 10 is arranged at a predetermined position in the lower strut member 8. Therefore, the upper strut member 10 can be fixed to a predetermined position of the lower strut member 8 by the connecting tool at the lower part of the upper strut member 10. Therefore, the length of the column can be expanded and contracted.

When it is in the holding state, it is not necessary to manually hold the pin in the retracted position. Specifically, these mechanisms are further realized by a pin cylinder 67 for accommodating the pin 63 and the coil spring 65 and a pin holder 69 for fixing the pin cylinder 67 to the upper strut member 10.

Similarly, the support column slider member 15 that connects the lateral lower end portion of the XXX type pantograph, which is the connecting means 30, so as to be displaceable in the axial direction of the support column 11, includes a positioning member, a position member, and an operation member. A holding state in which the pin 63 is held in the retracted position is realized by the same mechanism as the pin holding mechanism described above.

The positioning member is freely displaceable between a fitting position where it fits into the positioning hole and a retracted position retracted from the positioning hole, and when the strut slider member 15 is arranged at a predetermined position of the strut 11, the strut is made of a spring member. It fits into the positioning hole 71 formed in the support column 11 by the force in the direction toward 11. Specifically, the positioning member is realized by a pin 63 made of a hard metal such as iron. A spring member that gives a force to the positioning member in the direction toward the support column 11 is realized by a coil spring 65 or the like. The operating member makes it possible to operate the allowable state in which the positioning member such as the pin 63 is allowed to be displaced to the fitting position and the holding state in which the displacement to the fitting position is suppressed and held in the retracted position. Specifically, the operating member is realized by the ring 61. When a deep groove and a shallow groove are dug in the pin cylinder 67 and the ring 61 is fitted in the deep groove 95, the pin 63 is subjected to a force in the direction toward the column by the coil spring 65 and is displaced to the fitting position. When the ring 61 fits into the shallow groove 97, the pin 63 is held in the retracted position.

When the allowable state is reached, the pin 63 is applied with a force in the direction of the support column 11 by the coil spring 65, and is formed on the support column 11 when the support column slider member 15 is arranged at a predetermined position on the support column. It can be fitted into the positioning hole. Therefore, since the support column 11 and the support column portion slider member 15 can be fixed at a predetermined position of the support column 11, the deployment of the foldable tent can be completed.

When it is in the holding state, it is not necessary to manually hold the pin in the retracted position. Specifically, these mechanisms are further realized by a pin cylinder 67 for accommodating the pin 63 and the coil spring 65 and a pin holder 69 for fixing the pin cylinder 67 to the upper strut member 10.

Further, since the tip of the pin 63 is hemispherical, even if the strut slider member 15 is slightly displaced to a predetermined position on the strut while the pin 63 is in an allowable state, there is little damage to the strut and the fitting position is good. Can be guided.

Further, since the operating member is the ring 61, it is possible to easily put in and take out the finger when operating, and since this operating member also serves as a member to be held, the number of parts can be reduced and the cost can be reduced. Can be done.

FIG. 12 is a diagram showing a state in which the foldable tent is being folded. FIG. 13 is a front view showing a folded state of the foldable tent. The roof bar 19 is folded in half by moving the middle part downward. The end of the support bar 39 between the column roof bars slides at the end connected to the column 11, and the end connected to the roof bar 19 is rotated and folded by a hinge. The ends of the support bars 35 and 37 that are connected to the link member of the connecting means 30 are freely moved by the ball joint while the support bar connecting member 43 is rotating, and the ends that are connected to the roof bar 19 are the roof portion slider members. 33 slides and moves freely by the ball joint to be folded. In the folded state, it becomes very compact.

FIG. 14 is a perspective view showing a state in which the awning 47 of the foldable tent of the present embodiment is stretched. Normally, it is used with the tent 47 stretched. The awning 47 and the frame of the tent are fixed with a hook-and-loop fastener.

FIG. 15 is a perspective view showing a state in which the sidewall 49 is attached to the foldable tent of FIG. The sidewall 49 and the frame of the tent are fixed by a hook-and-loop fastener. When the sidewall 49 is attached, it is easily affected by crosswinds. In the foldable tent to which the present invention is applied, the strength is strong even when it receives a crosswind, so that the link member of the connecting means 30 and the frame such as the roof bar 19 can be used without bending.
