RACKS FOR BOTTLES, CANS AND GLASSES This invention comprises an improvement over the invention disclosed in my prior U.S. Pat. No. 3,759,593.

BACKGROUND OF THE INVENTION There are many instances when open top trays or racks for bottles, cans and glasses are contained within cabinets to whose interior'access may be had through openings formed in the tops of the cabinets. In this manner. the articles supported from the racks or trays may be readily withdrawn from the open tops of the cabinets until the supply of articles in the uppermost rack or tray is exhausted. Then, it is conventional to re move the uppermost rack or tray from the cabinet and to thereafter utilize the supply of articles disposed in the rack or tray therebeneath. However, a convenient means must be provided to elevate the next rack to an uppermost position within the cabinet in order that the articles therein may be most conveniently placed for ready access thereto through the open top of the cabinet.

- Racks and open top trays of the aforementioned type are many times utilized to support large numbers of articles of considerable weight and accordingly a full rack or tray of articles constitutes a load which is difficult to elevate. Accordingly, elevating structure is often provided in these types of cabinets for elevating vertically spaced trays or racks of articles disposed therein. Examples of previously patented structures of this type may be found in.U.S. Pat. Nos. 2,322,439; 2,614,020; 3,531,169 and 3,737,209;

BRlEF DESCRIPTION OF THE INVENTION The rack supporting structure of the instant inventioncomprises a guide structure defining an upstanding elevator passage having a support platform mounted therein for vertical movement therethrough. A lift structure is provided for lifting the platform and the guide structure includes variously actuatable support members or dogs for engaging and supporting vertically spaced racks in adjusted vertical postions within the guide structure. Further, the lift structure includes au tomatically actuatable abutment portions shiftable between operative and inoperative positions for engaging and lifting racks within the guide structure spaced above the support platform as the support platform is moved to a raisedpos'ition. In this manner, a plurality of vertically stacked racks may be elevated to predetermined postions and supported in those positions after which the support platform for the lowermost rack may be lowered to the bottom of the guide structure for the reception of a lower rack thereon to be subsequently elevated through the guide structure.

The mainobject of this invention is to provide a support and guide structure for a plurality of vertically spaced racks ortrays for supporting various articles and lift structure operatively associated with the guide structure for elevating the racks within the guide structure.

within the guide structure that will automatically sense the removal of the uppermost rack within the guide structure and function to elevate the next lower rack to the uppermost position within the guide structure.

Yet another important object of this invention is to provide manually operable actuator means for the lift structure which may be utilized to lift a plurality of reasonable heavily laden'racks within the guide structure with a minimum of effort.

A final object of this invention to be specifically enumerated herein is to provide an apparatus in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be econornically feasible, long lasting and relatively trouble free in operation.

latter. An L-shaped elevator member referred to in generalby the reference numeral 40 is provided and includes a pair of opposite side long vertical legs 44 terminating downwardly in horizontally inwardly directed short horizontal legs 46. The free ends of the horizontal legs 46 are pivotaly anchored to the correspondingfasteners and the fasteners 30 are also secured through slide plates 48 disposed in sliding contact with the .outer surfaces of the corresponding angle,

mcmbers

24 and 26. Also, the ends .of the short horizontallegs 46 adjacent the lower ends of the long vertical legs 44. of the elevator members are provided with rollers 5 0rollr'nay be placed on the longitudinal members 54 through manner, the elevator member 40 maybe swung from the solid line inoperative position thereof illustrated in phantom lines in FIG. 1 with the elevator bars 28 in elevated positions. I i y K a I The lower end portions of each pair of end corner members 12 have additional transverse brace members 52 secured therebetween spaced above the lower ends of the members 12 and the transverse members52 include parallel longitudinalsupport members 54 spaced transversely of the structure 10 secured .therebetween. The longitudinal members 54 are operative to..support a lower upwardly opening tray or rack 56 therefrom.

Each pair of vertically spaced

members

14 and 16 have a pair of front to rear spaced

upstanding support members

56 and 58 secured therebetween with each support member 56 and 58.spaced generally equally between a corner member 12 and the

adjacent angle member

24 or 26. g

A pair of vertically spaced cam frames 60 and 62 are supported from each support member 56 and 5 8 and a pair of vertically spaced

support brackets

64 and 66 are of spacer blocks 74 slidably received in the correspond-.- ing slot 34 and by means of fasteners 76 secured through the corresponding spacer blocks ,74 are, a pair of split support blocks 78 through which,..the fasteners 76 are secured. Each split support block 78 includes a pair of block sections 80 having opposing horizontal semi-cylindrical recesses 82. formed therein'and. each A pair ofopposing semicylindrical recesses defines acy- In addition, each split block 78 has a horizontally inwardly opening U-shaped frame 100 secured thereto by the fasteners 76 and including a pair of horizontally inwardly directed legs 102 including inner end inwardly directed abutment flanges 104 with which the legs 88 of the corresponding frames 86 are abutingly engagable to limit inwardly swinging movement of the free ends of the legs 88 of each frame 86 and the U-shaped feeler guides 92 supported.therefrom.

In operation, an upwardly opening basket or rack 56 the frontv of the structure 10 whenever the longitudinal members 54 do not have 'a rack supported therefrom. Then, if it isdesired to raise the rack 56, the elevator member 40 has the'upper ends of the long vertical'legs 44 thereof, which' upper ends may be rigidly interconnected' by mea ns of a horizontal connecting member (not shown), swung downwardly and outwardly to the phan tt'jm line position of the elevator member 40 illustrated in FIG. l"of the drawings. By thus angularly displacing the elevator member40, the elevator bars 28 are elevated between the vertical

guide angle members

24 and 26 movingthe splitblocks 78 upwardly therewith. As the lower frame 86 is elevated the legs 88 thereof ride upwardly along the corresponding pins 98 and allow "the frame '86 and the feeler guides 92 supported therefrom to angle inwardly over the basket 56.

In'ward tiltin'g of' the lower frames 86 is continued until the feeler guides 92'thereof abut theupper rim of the basket or rack 56 and the pins 94'engage the under portion of the upper rirn of-the rack 56. Thereafter, further upward movement of the elevator bars 28 elevates the -'rack'56. Upward movement of the rack 56 through the structure 10 causes the upper portionof the rack 56 to engage the ratchet dogs 68 so as to swing the latter outwardly toward their" retracted positions until the lower end of the rack 56 passes the upper portions of the lower ratchet dogs'68 whereuponthe latter are free to fall. inwardly beneath the rack 56 for support of the latter therefrom as soon as the elevator member 40 is swung from the phantom line position thereof illustrated in. FlGul to the solid line'position in order to lower the elevator bars 28.

With the first inserted rack 56 thus supported in elevated position above the longitudinal members 54 by the lower set of ratchet dogs 68, a second rack 56 may beplaced on the: longitudinal members 54. Then, if thei elevator member 40 is again actuated to raise the elevalindrical bore in which the bight portion 84 of a U shaped frame 86 is .oscillatably supported. Each frame 86 includesa pair of generally parallel legs 88 which terminate at their free ends in outwardly directed arms 90 having U-shaped feeler guides 92 and abutment pins ii 'tor bars 28 the upper ends of the lower feeler guides slide along the upper rack 56 until the free ends of the arms90engagethe lower cam frames at which point "the lower feeler guides 92 are swung outward to inopera tive positions. However, upper displacement of the elupper rack 56 as thelegs88 of the upper frame 86 slide upwardly along andover the corresponding pins 98.

frames 86 are slightly shorter than the frameguides-92 :4

of the lower frames 86.

Each of the vertical

guide angle members

24 and 26 includes a pair of vertically spaced horizontally outwardly directed abutment pins 98 with which the legs of the corresponding frames 86 are engagable. I.

Thus, the feeler guides 92 of the uppe r frame 86 incline inwardly over the upper basket 56 and thepins 94 of the upperframe 86 engage the upper rim of the, upper basket or rack 56 in orderto elevate the latter into position above the upper set of ratchet dogs 68. Of course,.after the rack 56 supported from the upper ratchet dogs6 8'is removedfrom the top of the struc- I ture l0 thelower rack 5.6 may be elevated tothe lower. set of ratchet dogs 68 and thereafter to the upper set,

of ratchet dogs 68 as hereinbefore's et forth.
