1o claims. (01.2.11-121) 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 inven-V tion 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 mprovement 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 I 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 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.
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 part of one of the trays broken away. i'
Figure 4 is a detail on line 4-4 of vFigure 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 arm S'I'through pins 38 and 39.
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 l0 having corner posts II and carriages I2.
The improvement of this invention includes means for reversing the mechanism at any point. To accomplish this the carriages I2 are provided with two rollers I3 and I4 positioned to contact lugs l5 on the trays I6 and also stationary lugs I'I at the upper end and lugs I8 at the lower end, wherein the rollers will engage the lugs before the carriage reaches the end of its travel. The roller I3 is rotatably mounted on a link I9 and the roller I4 is mounted on a similar link 20, the link I9 being pivotally mounted on the frame 2| of the carriage through a pin 22, and the link 2i) similarly mounted on a pin 23. The upper end of the link I9 is pivotally attached to an S-shaped lever 24 through a connecting link 25 with pins 26 and 21, and the lower end of the link 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 2| through a shaft 3| and a roller 32 in a slot 33 in the frame.
The operating element, or gear segment 34 is xedly mounted on the shaft 3I and another lever 35 is also xedly mounted on the shaft and the end thereof is connected by a link 36 to an The arm 3l is xedly attached to a pin 40 pivotally mounted in the frame 2l, and on the other end of the pin 40 is an L-shaped lever 4I 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 I6.
A spring 41 is provided in a recess 48 in the lever 35, and positioned around the shaft 3| to frictionally hold the levers to prevent movement thereof further than the positive actuation thereof by the gear segment 34. Compression springs 49 and 53 on studs 5I and 52 are attached through connectors 53 and 54 to the opposite ends of the lever 24 for normally restrain- Y 58 on the other.
" teeth i2 of the rack 7|.
ing the lever so that it may remain in the neutral position as illustrated.
The carriage frame 2i is provided with four hanged rollers 55, and 5S, on one side and 51 and These rollers contact opposite edgesof continuous tracks 59 upon which the carriages travel, and the outer rollers 55 and 56 are spaced further apart than the inner rollers 5l and 58 to facilitate travel thereof around the arcuate'formations at the upper and lower ends of the track. Thecarrages are also provided with extending lugs 60 by which they are pivotally attached to continuous chains 6I traveling over sprockets E2 and 53 on shafts 65 and 65, and the upper shafts 64 at the opposite endsY of the frame are rotated by gears 66 at therespective ends., of. a motor shaft 6l having a motor 68 associated therewith through suitable reduction gears. Thei motor may be controlled by buttons 69 and 10 at a convenient point on the frame whereby they" may be readily activated by an operator to raise or lower the trays as desired. Y
In operation, assuming that the oa'rriagefll" Yis moving upward from the position shown in Figure 2 the upper roller I3 will ride upward along the'row of lugs I5 on thetraysabove, thereby moving the roller and lever 2'4 outward, toward the upper rack 'il so thata'notch innthe end of the segment tdwillymesh with onefof'the Then asthe` carriage continues to travel upward .the to'otlrwillV rotate the segment 3d thereby through the. associated levers causing the L-shaped lever 4| to'move'the rollers l2 and d3 outward from the position shown in Figure 3, wherein a projection Non the latch E4 will moveV into an opening 'I5 in a, supporting angle le, and at thel same timezmove ing a projection Tl on the opposite side ofy the latch outr of an openingY 'i8 inv an arm 'i9 of. the carriage, thereby releasing the; carriage. The lowerroiler Id then contacts' the oppositeV sides of the lugs I5 and moves thelower'endof the lever 2 outward, away'from the rack. 1 Il, thereby releasing the segment" Sd'frorn the rack,1so. that the .carriage isfree to travel upward over the4 ISO upper sprocket and down theother side. In-the Vnormal operation of4 the cabinet two carriages are used, and these chain and track.
When the carriage is moving downward the lower roller Id will ride on the lugs I5 of the areV equally spaced' on the trays below and this will actuate'the lower end Y ofl the lever 2,4 so that thegear segment will` be moved to operative position wherein the notch di) will mesh with teeth 81 ofthe lower YrackLZ; and as the downward movement ofthe carriage continues the segment 34'. will operate'` the L-shaped lever @I which will actuatejthe'l'atch' to release the carriage. The upper roller |31 then rides on the lugs I5' andvactuates the lever` 14 wherein the upper end movesaway from the rack 82 thereby disengagingV the segmentL 341mm. Athe teeth of the rack. The additional'lugs lfllandl',
which are stationary, arerprovided .atthe upper Y and lower 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. nuorescent. tubes 83 in brackets 56 may be provided-in the corner sections ll of the frame and these may be mounted in recesses 85' or incorporated therein in any manner. Y
To pick up one of the trays at the lower. part of the cabinet the up button 691 is pressed and the carriages travel around the track` 59 in aV Y required:
counter-clockwise direction, and as a carriageY passes the trays the roller I3 rides oit of the lug I5 of the uppermost tray allowing the spring d to swing the lever 24 so that the segment 3K5 meshes with the teeth 8| of the rack 82 moving the projection TI of the latch #lll through Vthe opening 18 in the arm 'i9 of the `carriage so that the tray is picked up andV travels upward with the carriage. oi'of the lugs I5 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 Vreturn a tray fromthe trays in the upper part of the cabinet the movement is reversed and the down button 'i0 is pressed, and as the #carriage-passesfthe upper trays the roller Iii rides ofi-o. the last lug I5 allowing the spring 53 to swing the lever 24 so that the segment 3e meshes '|8` in the arm 19 of the carriage so that the tray is picked up and travelsv downward with the carriage: Then as the upper roller I3- rides oilV of thelugs" I5 of'- the-*last trayl above the spring @Si willmove' theleverZll back, thereby moving the segment 34-` out ofVV engagement with the Vteeth oi' the rack:
The movement ofthe traymay be stopped at any point, and the direction Vof travel thereof may be reversed at any time` as desired. Y
The tray is always carried inthe central part of the carriage and in-using the two rollers I3 and I4, one above and one below the tray it is possible'toactuate the mechanism for latching or unlatching th'e'tray before the tray reaches thel end-of'its`V travel, regardless of the'direction of travel.V
In thefcabinet of this design only one operatingn rack I5`l is required at each end, `whereas in the cabinet of my patent two such racks were The instrumentalities are now so arranged thatv theA operating gear segment 3ft is only in engagement with the rack long enough tov latchor unlatch the tray,V as after the tray is Ylatchedior`v unlatched it is movedout of engagementtherewith. The latches 4d havea rotating movement in a vertical plane thereby allowing for thervertical movement ofthe tray in-latchingvandunlatching. The guiderollers of the carriagetravelaround-a single bar 59, and with this des-ign.. itis possible. to use. comparatively small sprockets. at each end, over` which the chain travels. Y Y Y 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'rdesired may be used. Y
Itwill be.v understood that other changes may Vbe made in the design and construction without Vdepartingirom the spirit of the invention. Y
