REVERSIBLE RUG DISPLAY CABINET
Oscar Thor, Application November
Claims.
This invention relates to display cabinets and particularly cabinets for displaying rugs which are relatively large, and because the prospective purchaser prefers to see the rug in a horizontal position as it would be on the floor, this invention contemplates a frame adapted to accommodate a plurality of rug trays and means for raising and lowering the trays.
The rug cabinet of this invention is an improvement over the rug cabinet of my prior Patent Number 2,347,139, dated April 18, 1944, in that means is provided for readily reversing the instrumentalities so that a rug tray may readily be stopped and the mechanism reversed to move the tray in the opposite direction.
Various other improvements in the structural elements and operation will become apparent as the description proceeds.
The purpose of this invention is to provide a rug display cabinet wherein a plurality of trays having rugs thereon may readily be moved one at a time upward to the upper end of the cabinet, and then downward, and in which the direction of travel of the trays may be reversed at any time.
With these and other objects in view the invention embodies a rectangular shaped frame, a plurality of horizontally positioned trays suspended at the four corners in said frame, conveying chains in the corners to which the trays are removably attached, motive means for operating the chains in opposite directions, and means readily attaching and releasing the trays to and from the chains.
Other features and advantages of the invention will be readily understood from the following 35 description taken in connection with the drawings, wherein:
Figure 1 is a view showing the rug display cabinet with part broken away showing the operating gears at the upper end thereof. 4o
Figure 2 is a front elevation showing a post at one corner of the cabinet with part broken away illustrating the mechanism therein.
Figure 3 is a sectional plan through one corner of the frame with parts of the frame and also 45 part of one of the trays broken away.
Figure 4 is a detail on line 4—4 of Figure 5 showing a section through one of the tray operating carriages with parts broken away.
Figure 5 is a view showing a side elevation of 50
Nutley, N. J.
(, 1946, Serial No. 707,580 (Cl. 211—121) one of the tray holding carriages with parts broken away.
Figure 6 is a detail showing an end view of one of the carriages with parts broken away.
Referring now to the drawings wherein like reference characters indicate corresponding parts the rug cabinet of this invention includes a frame 10 having corner posts li and carriages 12.
The improvement of this invention includes 10 means for reversing the mechanism at any point. To accomplish this the carriages ί 2 are provided with two rollers (3 and 14 positioned to contact lugs 15 on the trays 16 and also stationary lugs 17 at the upper end and lugs 18 at the lower end, 15 wherein the rollers will engage the lugs before the carriage reaches the end of its travel. The roller 13 is rotatably mounted on a link (9 and the roller (4 is mounted on a similar link 20, the link 19 being pivotally mounted on the frame 21 20 of the carriage through a pin 22, and the link 20 similarly mounted on a pin 23. The upper end of the link 19 is pivotally attached to an S-shaped lever 24 through a connecting link 25 with pins 26 and 2T, and the lower end of the link 25 20 is connected to the lower end of the lever 24 through a connecting link 28 and pins 29 and 30. The lever 24 is pivotally and slidably mounted on the carriage frame 21 through a shaft 3 f and a roller 32 in a slot 33 in the frame.
The operating element, or gear segment 34 is fixedly mounted on the shaft 31 and another lever 35 is also fixedly mounted on the shaft and the end thereof is connected by a link 36 to an arm 37 through pins 38 and 39. The arm 37 is fixedly attached to a pin 40 pivotally mounted in the frame 21, and on the other end of the pin 40 is an L-shaped lever 41 on the upper end of which are two rollers 42 and 43 which engage and operate the latch 44 pivotally mounted on a bracket 45 extending outward from each corner of the trays, which are indicated by the numeral 16.
A spring 47 is provided in a recess 48 in the lever 35, and positioned around the shaft 31 to frictionally hold the levers to prevent movement thereof further than the positive actuation thereof by the gear segment 34. Compression springs 49 and 56 on studs 51 and 52 are attached through connectors 53 and 54 to the opposite ends of the lever 24 for normally restrain2,696,291 ing the lever so that it may remain in the neutral position as illustrated.
The carriage frame 21 is provided with four flanged rollers 55, and 55, on one side and 57 and 58 on the other. These rollers contact opposite edges of continuous tracks 59 upon which the carriages travel, and the outer rollers 55 and 56 are spaced further apart than the inner rollers 57 and 58 to facilitate travel thereof around the arcuate formations at the upper and lower ends of the track. The carriages are also provided with extending lugs 80 by which they are pivotally attached to continuous chains 61 traveling over sprockets 62 and 63 on shafts 64 and 65, and the upper shafts 64 at the opposite ends of the frame are rotated by gears 66 at the.respective ends. of. a motor shaft 67 having a motor 68 associated therewith through suitable reduction gears. The: motor may be controlled by buttons 69 and 70 at a convenient point on the frame whereby· they may be readily activated by an operator to- raise, or lower the trays as desired. ·
In operation, assuming that the carriage 12 is moving upward from the position shown in Figure 2 the upper roller 13 will ride upward along the row of lugs 15 on the. trays .above, thereby moving the roller and lever 24 outward toward the upper rack 71 so that a notch in.the end of the segment 34 will , mesh with one of the teeth 72 of the rack 7J. Then as the.carriage continues to travel upward the tooth will rotate the segment 34 thereby through the associated levers causing the L-shaped lever 41 to move the rollers 42 and 43 outward from the position shown in Figure 3, wherein a projection 74 on the latch 44 will move into an opening 75 in a. supporting angle 76, and at the'same time.moving a projection 77 on the opposite: side of the latch out of an opening. 78 in an arm 79 of, the' carriage, thereby releasing the:, carriage.. The lower roller 14 then contacts the opposite sides of the lugs 15 and moves the. lower end . of'the lever 24 outward, away from the rack. 7 I, thereby releasing the segment 34 from the rack;.so: that, the .carriage is free to travel upward over the' upper sprocket and down the other side. In-the normal operation of. the cabinet two carriages are used, and these are equally spaced on the chain and track.
When the carriage is moving downward the lovzer roller 14 will ride on the lugs IS of the trays below and this will actuate the lower, end of the lever 2.4 so that'the . gear segment will be moved to operative position wherein the. notch 89 will mesh with teeth 81 of. the lower rack: 82, and as the downward movement, of the carriage continues the segment 34. will operate; the L-shaped lever 41 which will actuate the latch 44 to release the carriage. The upper roller 13 then rides on the lugs 15'and actuates the lever 24 wherein the upper end moves, away from the rack thereby disengaging the segment. 34.from, the teeth of the rack. The additional'lugs 17 and 18, which are stationary, are provided at. the. upper and lovzer ends for latching and unlatching, the top tray and the next to the lowest tray.. The bottom tray 46 is stationary.
Lighting elements such as. fluorescent, tubes in brackets 84 may be provided in the corner sections 11 of the frame and these may be mounted in recesses 85 or incorporated therein, in any manner.
To. pick up one of the trays, at the lower part of the cabinet the “up” button 69: is pressed, and the carriages travel around the track 59 in. a counter-clockwise direction, and as a carriage passes the trays the roller 13 rides off of the lug 15 of the uppermost tray allowing the spring 49 to swing the lever 24 so that the segment 34 meshes with the teeth 81 of the rack 82 moving the projection 77 of the latch 44 through the opening 78 in the arm 79 of the carriage so that the tray is picked up and travels upward with the carriage. Then as the lower roller 14 rides . off of the lugs 15 of the adjoining tray the spring 50 will move the lever 24 back, thereby moving the segment 34 out of engagement with the teeth of the rack. The tray may be stopped at any point, and as it reaches the upper trays it is automatically released from, the carriages as hereinbefore described.
To return a tray from, the trays in the upper part of the cabinet the movement is reversed and the down” button 70. is pressed, and as the carriage passes the upper trays the roller 14 rides off of the last lug 15 allowing the spring 50 to swing the lever 24 so that the segment 34 meshes with.-the teeth 72 of the rack 71 moving the projection 77 of the latch 44 through the opening 78 in the arm 79 of the carriage so that the tray is picked up and travels downward with the carriage; Then as the upper roller 13 rides off of the lugs 15- of the last tray above, the spring 49 will move the lever 24 back, thereby moving the segment- 34 out of engagement with the teeth of the rack
The movement of the tray may be stopped at any point, and the direction of travel thereof may be reversed at any time as desired.
The tray is always carried in the central part of the carriage and in using the two rollers 13 and 14; one above and one below the tray it is possible to actuate the mechanism for latching or unlatching the tray before the tray reaches the end of its travel, regardless of the direction of travel.
In the cabinet of this design only one operating rack 15' is- required at each end, whereas in the cabinet of my patent two such racks were . required; The instrumentalities are now so arranged that the, operating gear segment 34 is only in engagement with the rack long enough to latch or unlatch the tray, as after the tray is latched ar. unlatched it is moved out of engagement therewith. The latches 44 have a rotating movement in a vertical, plane thereby allowing for the vertical movement of. the tray in latching, and unlatching. The guide rollers of the carriage,travelaround a single bar 59, and with this design it is possible to use. comparatively small sprockets., at each end, over which the chain travels.
The frame may be of any type or design, and the motor' may be located at any point, or as many motors as may be desired may be used.
It will be: understood that other changes may be made in the design and construction without departing from the spirit of the invention.
