Pin-type lock with axial split cylinder and/or plug

[Detailed Description of the Invention]

(Field of the Invention) The present invention relates to a pin type key operation type lock, and relates to the pin type key operation type lock which passes along each maximum side edge of the pin hole whose at least one of the cylinders and plugs which were especially divided in the direction of an axis continuously have both and the crack for division adjusted preferably in the direction of an axis. In this way, although either a cylinder or a plug and both are formed by this peculiar method, when this is assembled and a pin type key operation type lock is made, these will operate by the usual method and Across use can be carried out during the long life. It has the cylinder and plug which were made from each single parts by which almost all the conventional composition of the pin type key operation type lock was fabricated, otherwise manufacture To was carried out, and the required pin Opening part key slot was formed in these. Formation of a Ping hole is in very precise work, and it is clear that it is comparatively difficult to carry out. It must stop to the heart that the pin hole of a cylinder must be adjusted exactly as appropriately as the pin hole of a plug so that the final lock can operate appropriately. One of the biggest problems that carried out the You intermediary encounter forming the conventional cylinder and plug with adjusted various pin holes of a lock is performing this formation at a rational manufacture speed, forming a pin hole between a cylinder and a plug so that it may consistent exactly. These pin holes have a very small diameter, and a portion tends to separate from the Equivalent from the request way of a pin hole during formation for many reasons. The piece of a scrap should arise at an in this way comparatively big rate, otherwise these should serve as parts of a suitable lock, and it is Oh. The trial which forms the cylinder and/or plug of the usual die-casting or the half part divided in the direction of an axis by forge is Oh partly conventionally. In all the cases, each cylinder or plug divided these into the direction diametral direction of an axis precisely through the center of a pin hole, ranked next, and it was formed by assembling these and making a final cylinder or plug. However, in order to provide a still extreme problem and to obtain the pin hole of a final request, the suitable consistency of a pin hole must form both the half parts of a cylinder or a plug carefully, and must machine them. (The object and outline of an invention) therefore, the object of the present invention -- either one of a lock cylinder and a lock plug -- or Both are divided into the line which serves as one direction edge of an axis of a pin hole in the direction of a Along axis, It is in providing the pin type key operation type lock which has the pin hole which one parts of the pin hole were formed in each pin hole of the even field passing through between Along and a pin hole, and was formed as a slot where the parts of another side were prolonged radially, and forms the pin hole adjusted in the direction of an axis by these two junction. In this way, since this is mere fields level, the portion of the pin hole formed in one parts is made easily, and although the portion of the pin hole formed in the parts of another side is a more complicated outside, since an intermediary opening is carried out to parts in Mukai completely [ while ], this slot is similarly formed without complication. The assembly which makes this part in a well-known common lock is performed quickly these parts are not only easily formed in exact size shape, but, and Across use of this lock can be carried out during the long life. It is although the pin hole of one parts is a thing of an always even outside in an example with the preferred object of the present invention, Although the pin hole formed in the pin hole of another side is formed as a slot, there is in providing the pin type key operation type lock of the structure mentioned above which is a thing of a different slot outside according to the last formation thing with the pin of intermediary To have each a desired pin hole and operating in this. For example, in a desirable form, as for a pin hole, an outside is formed in D shape, the opening of the D-shaped slot is carried out toward the even field of the parts of another side, and the round pin operates as in this kind of most ordinary lock in it. However, as long as it is a request, the pin hole of the outside of others of a pin, for example, a rectangle with a rectangular pin, and the pin hole of a rectangle with a rectangular pin may be used, without adding an extreme change to the outside of a pin hole and a pin. It is clear to provide very much structure using the principle of the present invention. The other objects and advantages of the present invention will become clear from the following the detailed explanation and accompanying drawings that are the things only for explanation. (EXAMPLE) Reference of drawings illustrates the pin type key operation type lock which carries out the division cylinder and/or plug principle of the present invention. A group also stands Drawings 1 thru/or 7 to an operation form, Locked tablets is shown, and Drawing 8 is an exploded view shown where most parts of a lock are disassembled. In order to raise plainness, the cover for a front part ornament is removed in all the drawings. When the lock of an assembly state shown by 10 on the whole is examined first, and the cylinder and/or plug division principle of the present invention are disregarded for a while, lock 10 is, Plug 14 is inserted in telescopically, it has cylinder 12 which attaches plug 14 enabling free rotation, and this plug has key slot 16 which accepts ordinary key 18 and which was prolonged perpendicularly. It has comparatively short front flange 20 at a front end, it ranks second to it, projects back, and cylinder 12 becomes sleeve 22 in the air. Pin holding portion 24 which is prolonged to sleeve 22 in Along back at the back portion of the front flange 20 and which was prolonged in the perpendicular upper part is formed in cylinder 12. Similarly, bolting portion 26 prolonged in a lower part from a cylinder is positioned by cylinder 12, and this bolting portion exists in it for a certain object mentioned below. Plug 14 has comparatively short front flange 28, and front flange 20 of a cylinder is, The greater part of this front flange 28 is made to fit in telescopically, and plug 14 is, Subsequently, in circular section drive object 30, it is covered with sleeve 22 of a cylinder, and extends back, and this drive object 30 comes out of the sleeve of a cylinder finally as a Or movements type drive connecting part, i.e., plug drive connecting part 32. Plug drive connecting part 32 finishes with socket 34 which carried out the opening to back, and as this socket shown in Drawing 3, it has interference member 36 prolonged on both sides in the inner direction face to face. Intermediary ing [ as ] by which socket 34 of plug drive connecting part 32 accepts a front end of torque braid 38 into it by this as shown especially in Drawings 3 and 4. A torque braid has same interference member 40, and this interference member 40 engages with interference member 36 of a plug, and it is positioned [ it is the usual method, and ] so that movement connection may be performed from that between this interference member 40 and interference member 36. A torque braid is held at plug drive connecting part 32 so that an operation is possible, and enables alternative movement with Latchch and the dead bolt by lock 10 in the usual method in movement connection at the torque braid concerned from usual one with lock 10 so that it may illustrate. Color 42 and spring 44 fix lock 10 to the knob assembly object which is not illustrated. In detail, if key 18 is inserted in key slot 16, pins 50 and 56 will be positioned so that Along consistency may be carried out at division line 58, when it sees [ the engaging-of-clutch portion of the pin which each set accumulated ] in Drawings 4 and 5. Subsequently, key 18 (Drawing 5) is turned and plug drive object 30 is moved by this (namely, rotation). Since plug drive connecting part 32 is formed in one with plug drive object 30 (refer to the 8th figure), connecting part 32 moves it similarly. Interference member 36 (Drawings 3 and 8) is prolonged in one from the inner wall of plug drive connecting part 32. Interference member 36 moves in the inside of opening socket 34 (namely, Or movements), and engages with the both ends of the pin which penetrates a torque braid, i.e., interference member 40, finally so that it may understand best in Drawing 3. As for these, connection Monkey is not illustrated by this application by Latchch mechanism [ like the ordinary portion of a lock, i.e., a dead bolt, and a latch bolt ] whose torque braid 38 is. Therefore, plug drive object 30 is formed in one, and if key 18 is turned, via the element of the versatility mentioned above which carries out mutual engagement, torque braid 38 will be driven, a dead bolt will be drawn in or it will remove locking of a latch bolt. When an assembly form still examines lock 10, without taking into consideration the cylinder and/or plug division principle of the present invention, cylinder 12 is, In sleeve 22 and pin holding portion 24, it has pin hole 46 adjusted in many directions of an axis, and this pin hole 46 is prolonged in the perpendicular upper part from plug 14. Plug 14 is prolonged radially and has same pin hole 48 adjusted in the direction of an axis on drive object 30, and this pin hole 48 adjusts it with pin hole 46 of a cylinder in the illustrated neutral position, for example, as shown in Drawings 4 thru/or 7. The opening of the pin hole 46 of a cylinder is altogether carried out to the upper part from cylinder 12, an opening is carried out to a Mukai or intermediary lower part at drive object 30 of a plug, the opening of the pin hole 48 of a plug is carried out to sleeve 22 of a cylinder in the Mukai or intermediary upper part, and it leads below in key slot 16 of a plug. Cylinder pin 50 of various length is positioned by pin hole 46 of a cylinder, and this pin 50 is supported with spring 52 for pins in the upper part, and is covered with general Snap-on Incorporated type pin holder cover 54. When same plug pin 56 was positioned by pin hole 48 of the plug, and this plug pin 56 is attached to cylinder pin 50 at the method of outside, and it projects in key slot 16 to an inner direction or key 18 is inserted in lock 10, the outline of key 18 is contacted. In the position shown in Drawings 4 and 5 in this way, Cylinder pin 50 and plug pin 56 are positioned so that division line 58 may come exactly between cylinder 12 and plug 14, and thereby, a suitable key can rotate a plug and can operate lock 10 by the usual method. In the cylinder of the present invention and/or a plug division principle, and this example, about both cylinder 12 and plug 12, more particularly, divide completely in the direction of an axis and form these in it at the beginning to be shown in Drawing 8, respectively -- it ranks next, and is mutually assembled on the occasion of the assembly of lock 10, and the lock finally completed is formed. Cylinder 12 has division line 60, and this division line passes along front flange 20, sleeve 22, pin holding portion 24, and bolting portion 26 perpendicularly, and forms a Along half part in a diameter mostly so that it may illustrate. Similarly, division line 62 is formed also in plug 14, and this division line 62 passes along a movement type drive connecting part, i.e., plug drive connecting part 32, and key slot 16 perpendicularly from front flange 28 and drive object 30. In this way, division line 60 of a cylinder divides cylinder 12 into a diameter mostly at Along other side It matched parts, i.e., cylinder right parts and a cylinder left part article, when it sees from the front of a lock in Drawing 2. Similarly, plug 14 is mostly divided into Along, plug right parts, and a plug left part article in a diametral direction. each division line 60 and 62 was prolonged in the direction of an axis of all the pin holes of each pin holes 46 and 48 of cylinder 12 and plug 14 -- while -- an edge and this example -- a cylinder -- one side -- Along and a plug -- the another side side -- Pass along -- things -- the principle of the present invention -- an intermediary -- it is important. When it sees in Drawing 6, division line 60 of a cylinder forms even field 72 in cylinder left part article 66 between pin holes 46 of a cylinder, and U form hole which separated the interval, i.e., U form slot 74, is formed in Syringe right part 64 so that pin hole 46 of a cylinder may be completed. As are mentioned above, and plug 14 is shown in Drawing 7, opposite Fitted together formation is carried out exactly, and plug right part 68 forms even field 76 between pin holes 48, and the hole which separated the interval so that pin hole 48 of a plug might be completed, i.e., slot 78, is formed in plug left part article 70. Pin holes 46 and 48 finally formed are adjusted regardless of the method of forming these in the neutral position of lock 10, and this composition of the illustrated specific example should understand at the end that it is only a selection matter. Intermediary To have [ as ] in which the specific size of slots 74 and 78 of pin holes 46 and 48 stores cylinder pin 50 and plug pin 56 in the pin of a section with a round pin hole, and this example. Pin hole 46 of a cylinder is more slightly [ than pin hole 48 of a plug ] long again, and the diameter of the pin hole of a cylinder is 3.2 mm (0.125 inch) especially to the diameter of the pin hole of a plug being 3 mm (0.12 inch) in this example. however -- the principle of the present invention is not what is limited to To which uses only a round pin -- the pin hole slot on the cylinder, and the pin hole slot on the plug -- a square and a rectangle -- or In order to store the pin of other sections like an ellipse, it should stop to the heart that it can make in a relatively different size. It is formed as a You intermediary is shown in Drawing 8 manufacturing and assembling lock 10 from cylinder 12 and plug 14 with the usual manufacturing method [ like die-casting ] whose The cylinder left, right parts 64 and 66 and the plug left, and right parts 68 and 70 are. As the cylinder left and right parts 64 and 66 were assembled and mentioned above, pin hole 46 is formed and engaging of clutch of the block 80 is carried out to crevice 82. It is formed in bolting portion 26 of a cylinder, and Hook 80 and crevice 82 are the assembly objects of cylinder 12, Probably, it turns out that it is maintained by carrying out engaging of clutch of the lower side of a bolting portion to snap cover 88 of about U type so that 64 cylinders of cylinder right part left part article 66 may not dissociate. The plug right and left part article 68 and 70 are assembled similarly, and as mentioned above, it has the composition of pin hole 48 of a plug, and has engaged bars 84 and 86 further. Although rank next, plug 14 is inserted in cylinder 12 from the front, and various pins 50 and 56 supported with spring 52 for pins are inserted in pin holes 46 and 48 and being snap Fit carried out of the pin holder cover 54 to a proper place, This cover 54 is useful to hold pins and these springs in a proper place, and to hold the whole cylinder assembly object. Color 42 and its spring 44 are assembled at the end, and the whole lock assembly is held. therefore -- according to the principle of the present invention -- one side of a pin type key operation type lock, i.e., cylinder 12, and plug 14 -- or although the both are divided in the direction of an axis, in the last assembly object, lock 10 which operates by the usual method is provided. Both Cylinder 12 and plug 14 are divided in the illustrated specific example, and the line of division is Along to one pin hole 46 and 48 side. In this way, one parts of cylinder 12 and plug 14 acquire all the advantages of this new thing to divide, being formed as even parts, and a slot being formed in the parts of each another side, and simplifying composition comparatively by this. The pin hole precisely formed in each of cylinder 12 and plug 14 loses completely point Stand up and the problem accompanying [ can form very easily and ] the conventional structure to formation of the pin which this part assembled and adjusted to divided various parts. Although the lock structure of a specific example has explained the principle of the present invention, since the principle of the present invention is easily applicable to the lock structure of the form of various others, it does not mean restricting this principle only to this structure. In this way, the principle of the present invention should be interpreted widely and should not be limited more than the specific limitation indicated to the claim.
