HEAVY DVTY UNIVERSAL
ADJ~STABLE SLIDER FOR FOOD SERVICE CART
Back~round of the Invention Field o~ the Invention This invention relate~ to food service carts and, more particularly, to adjustable slides for accepting food trays or pans.
Background Art Food preparation operations catering to large volume clients such as hotels, restaurants, hospi~als and the like, generally use stainless steel food sexvice carts.
The carts are wheel equipped and insulated to maintain conditions in the food storage space to preserve the warm or cold s~ate of the food between the time of loading in lS the food preparation area and the time of delivery to the ultimate consumer.
Normally, these carts are provided with internal upright structural columns which carry horizontal supports called slides or sliders, which accept and _d support trays or pans upon which the food is placed.
After being filled, the cart doors are closed and sealed and the carts loaded upon trucks for delivery to the consumer. At the point of destination the carts are unloaded and wheeled to a convenient point for ~5 distribution of the contents.
Several serious problems have occurred with such operations which, to date, have not been adequ~tely dealt with by prior art designers. During handling, the filled carts may tip or be jostled which oft times causes the slides to dislodge, dumping the food contents into adjacent pans or ~he bottom of the cart. Permanent mounting of the slides to prevent dislodging precludes adjustability of the sliders which seriously compromises the versatility of the carts to carry the usually employed different sizes of food trays.
Another drawback with the prior structures is that the slider mounting elements are prone to failure under the substantial weight of the filled pans and trays. A
typical mounting structure for each slider uses two ta~s struck directly from the material o~ the slider, each tab opening and being directed transversely from the other.
Preferably one of ~he tabs is extendable horizontally into a slot in one of the uprights and upon being fully seated situates a downwardly opening tab in alignment with a slot into which it can be dropped. If either tab breaks or dislodges, the entire slide fails. If vibration raises the downwaxdly open tab sufficiently to clear its upright slot, the entire slider may become dislodged.
Another serious deficiency in the art is in the area of the slide type termed ~universal" in the field. The universal slide normally defines a two shelf support, with each shelf capable of accommodating different width trays or pans~ Heretofore, each universal type slider has been suspended from the uprights in cantilever-type fashion. To avoid unwanted flexing of the free end as might release the trays, the entire slider has generally been formed from a heavy gauge material. The use of a heavy material undesirably adds to the weight of ~he cabinet, complicatës handling and increases the cost of manufacturing. Alternatively, braces might be bolted, welded, or otherwise secured to reinforce the slide shelves, additionally adding to weight and cost undesirably.
The present invention is specifically directed -to overcoming one or more of the problems in the prior art structures that are enumerated above.
Summary of the Invention Thus broadly, the invention pertains to a one-piece, universal type sheet metal slider for a food service cart of the type having a cabinet with inside, facing walls to which a plurality of the sliders are mountable for slidably accepting food trays. The slider includes a first, flat shelf for supporting an end of a tray having a first width, with the first shelf having opposite ends, and a second shelf is parallel to the first shelf for supporting an end of a tray having a second width less than the first width.
A panel portion connects between the first and second shelves and is substantially at righ-t angles thereto, and a gusset is integral with and folded perpendicularly to the plane of the first shelf in depending fashion at one end of the first shelf and has oppositely facing first and second edges. The first gusset edge is situated adjacent the panel, with the second gusset edge being situated adjacent one of the facing walls, so that the gusset simul-taneously reinforces one end of the first shelf and limits movement of the panel toward one of the facing walls. Means ~S detachably mount the slider to one of the facing walls.
More particularly, each slider is preferably formed from a single blank of relatively thin gauge bendable material.
The blank is preformed with a substantially rectangular body having a mounting tab and gusset plate extending lengthwise beyond each opposite end of the body.
3a The body is bent about a series of lengthwise, parallel fold lines to define a flat face for enga~ement with a vertical column wall of the cart and a first horizontal shelf offse~ from and continued into a second, lower shelf, which terminates at the free end of the slider. A mounting tab is bent at a right angle to the plane of the vertical face at each end of the body. To reinforce the shelves, the gusset at each end of the body is folded under the first shelf and bears between the column wall of the cart and the offset between shelves, providing a positive deterent to collapse of the outermost shelf of the slider under influence of a loaded food tray supported upon that shelf.
The principal objective of the invention is to provide a universai-type slider that is rugged yet which can be simply formed from a single blank of thin material without the provision of separate reinforcing elements or the performance of separate welding steps.
~5 It is another aspect of ~he invention to provide a mounting tab that cooperates with ~he remainder of the slidPr structure to positively loca~e the slider on the cart yet permit manual repositioniong of the same within the cart to properly accept food trays, pans and racks of differing size and configuration.
To accomplish ~he foregoing, ~he mounting tab comprises an elonyate body spaced from the rectangular hlank body by a stem which makes a T-shape with the tab bod~. A leading edge of each tab is airected into a slot in a cart upright and advanced upwardly suf ficiently to present the trailing edge of the tab at the bottom of the slot. The enti~e slider is then pivoted toward the upright and dropped down to capture the wall of the 1~ uprig~t bet~een the vertical face of the slider and a facing edge of the tab body.
Accordingly, horizontal shifting of the slider is prohibited without vertically shifting the slider relative to the mounting upright to disengage the tabs.
The weight of the food on the sliders prevents this vertical shifting as well as preventing disengagement of the slider from the column under vibrational movement of the slider in an up and down direction.
A further object is to provide a slider both universal in use, and easily installed and removed for cleaning as well as being readily formable from materials preferred for use in food handling e~uipment.

Detailed Descr_ption of the Drawin~s A food service cart, to which the present invention is adaptable, is illustrated in Fig. 1 at 10. ~he cart 10 comprises a cubical cabinet 1~ defined by side walls 14, 16, top wall 18~ bottom wall 19 and rear wall 20.
The open front edge 22 of the cabinet 12 is seal~d by a hinged door 24. The walls 14, 16, 18, 19, 20 and door 24 are preerably ~ade from stainless steel and insulated to maintain conditions within the cabinet consistent with the preservation of food stored in the cabinet 12.
The cabinet is mobilized by providing a wheeled platform 26. Handling of the cart is facilitated by mounting a handle 28 on at least one of the side walls 14, 16.
~5 The cabinet is framed internally. The frame includes uprights or columns 30, 32 at the front and rear, of the cabinet, respectively for accepting the tray supportin~ sliders 34. Vertically spaced slots 36 are provided in each of the uprights at corresponding heights on the four uprights 30, 32. The sliders 34 on opposite side walls 14, 16 are mirror images of each other and L~
located a~ the same height to maintain the trays 3B
carrying the food horizontally, levelly situated.
Figs. 3 and 5 best illustrate the construction of the universal slider. The slider 34 comprises a vertical wall 40 which bears facially against the adjacent wall surface 42 of the uprights 30, 32. Beneath the wall 40 is a first horizontal shel~ 43 and a second~ lower, horizontal shelf 45 connected by a vertical panel 47.
Food pans and trays are generally rectangular. The 1~ supporting axea of ~he shelves is such that a flange on the pan or ray may rest upon one set of shelves or the other with sufficient looseness to allow the pan or tray to be manually pushed into the cart by sliding the ~lange over the suppoxting shelves. The upright sur~aces 40 or 4~ serve to retain the food pan or tray against excessive movement once inserted in the cart. A tray or pan of narrower width can be confined on the second shelves, whereas it would otherwise shift freely and undesirably between the cabinet side walls 14, 16 on the first shelves 43.
To form the sliders 34 according to the present invention, a blank, as depicted in Fig. 2 at 49, is cut ~rom a stainless steel sheet on the order of 16 gauge thickness. The blank 49 comprises a substantially ~5 rectangular body 51 with mounting tabs 53 and gussets 55 extending lengthwise beyond the ends 57, 59 of the body 51. First, second, third and fourth fold lines are indicated by dotted lengthwise lines on the blank and respectively desig~ated 61, 63, 65, 67.
The vertical wall 40 is defined between the first and second fold lines; the first shelf 43 between the second and third lines; the panel 47 between the third and fourth lines; and the second shelf 45 beyond the fourth line. The blank is folded about ~he first, second, third and f~ur~h fold lines in stepwise fashion to arrive at ~he Fig. 3 configuration for the body 51.
An upper reinforcing flange 69 is folded about the first line 61 into parallel relationship with the first shelf 43. The flange 69 xeinforces the wall 40 against defelction from a load applied to the shelves as well as providing a shelf for large food tray receipt, if desired.
The gussets 55 comprise an exten~ion of the first shelf beyond the ends 57, 59. The degree of extension lengthwise of the body 51 beyond the ends 57, 59, which represents the length of the gusset on the formed slider, is a matter of choice. Pxeferably, to maximize support and minimize the amount of material, the gusset height is equal to the width of the panel 47 between the third and fourth fold lines. It can be seen most clearly in Fig. 5 that, with the gusset bent downwardly and perpendicular to the plane of the first shelf 43, the gusset edges 71, ~ 73 align closely with the upright face 75 of the panel 47 and the upright wall surface 42 on the upright.
Consequently, downward bending of the shelf 43 is prohibited by the gusset bearing on the surface 42. At the same time, downward deflection of the second shelf 45 ~5 is arrested upon the offset surface 75 encountering the edge 71 of the gusset.
A desirable feature of the invention is ~hat a rugged slider can be formed from a thin gauge material without welding or using fasteners. The formation of the slider involves simply stamping a blank and folding the blank in a prescribed manner.
The mounting tabs 53 are used to anchor the sliders to the uprights. Each mounting tab comprises an elongate $~.
body 77 having a leading edge or nose 79 and a trailin~
edge 81. The vertical wall 40 is Pxtended beyond the ends 57, 59 of the blank to define a stem 83 which defines a T-shape with the body and spaces the t~b body 77 from the er)ds 57, 59 of the rectangular blank body 51.
To assemble the slider, the slider is dispo~ed at an angle with respec~ to the upright 30 as indicated in Fi~.
4. The rounded nose 79 of each tab is introduced to a slo~ and ex~ended until the upper edge 83 of the slot abuts the juncture of the stem and the leading portion 85 of the body 77. The entire slider is pivoted about the point of abutment in the direction of the arrow 87 in .
Fig. 4 to direct the trailing edge 81 of the body 77 ~ehind the inside surface 89 of the upright, at which point the surface 92 of the face 40 facially abuts the wall 42 of the upright. The slider is locked by dropping the slider downwardly to its Fig. 5 position. In this position, the wall 95 of the upright is captured closely between the wall 92 of the wall 40 and the mounting tab body 77.
The slider is positively captured because the mounting tabs cannot be removed without tilting the slider away from the uprights. Because the weight of the loaded trays bears the sliders toward their locked ~5 position, the likelihood of inadvertently freeing the ~liders is reduced.
The foregoing detailed description was made for purposes of demonstratin~ the structure and operation of the invention, with no unnecessary limitations to be understood therefrom.
Fig. 4 is a fragmentary, sectional view of one of the sliders partially inserted into a mounting upright on the cart; and Fig. 5 is a fragmentary, sectional view of one of the sliders fully seated in the mounting upright.
Detailed Descr_ption of the Drawin~s A food service cart, to which the present invention is adaptable, is illustrated in Fig. 1 at 10. ~he cart 10 comprises a cubical cabinet 1~ defined by side walls 14, 16, top wall 18~ bottom wall 19 and rear wall 20.
The open front edge 22 of the cabinet 12 is seal~d by a hinged door 24. The walls 14, 16, 18, 19, 20 and door 24 are preerably ~ade from stainless steel and insulated to maintain conditions within the cabinet consistent with the preservation of food stored in the cabinet 12.
The cabinet is mobilized by providing a wheeled platform 26. Handling of the cart is facilitated by mounting a handle 28 on at least one of the side walls 14, 16.
~5 The cabinet is framed internally. The frame includes uprights or columns 30, 32 at the front and rear, of the cabinet, respectively for accepting the tray supportin~ sliders 34. Vertically spaced slots 36 are provided in each of the uprights at corresponding heights on the four uprights 30, 32. The sliders 34 on opposite side walls 14, 16 are mirror images of each other and L~
located a~ the same height to maintain the trays 3B
carrying the food horizontally, levelly situated.
Figs. 3 and 5 best illustrate the construction of the universal slider. The slider 34 comprises a vertical wall 40 which bears facially against the adjacent wall surface 42 of the uprights 30, 32. Beneath the wall 40 is a first horizontal shel~ 43 and a second~ lower, horizontal shelf 45 connected by a vertical panel 47.
Food pans and trays are generally rectangular. The 1~ supporting axea of ~he shelves is such that a flange on the pan or ray may rest upon one set of shelves or the other with sufficient looseness to allow the pan or tray to be manually pushed into the cart by sliding the ~lange over the suppoxting shelves. The upright sur~aces 40 or 4~ serve to retain the food pan or tray against excessive movement once inserted in the cart. A tray or pan of narrower width can be confined on the second shelves, whereas it would otherwise shift freely and undesirably between the cabinet side walls 14, 16 on the first shelves 43.
To form the sliders 34 according to the present invention, a blank, as depicted in Fig. 2 at 49, is cut ~rom a stainless steel sheet on the order of 16 gauge thickness. The blank 49 comprises a substantially ~5 rectangular body 51 with mounting tabs 53 and gussets 55 extending lengthwise beyond the ends 57, 59 of the body 51. First, second, third and fourth fold lines are indicated by dotted lengthwise lines on the blank and respectively desig~ated 61, 63, 65, 67.
The vertical wall 40 is defined between the first and second fold lines; the first shelf 43 between the second and third lines; the panel 47 between the third and fourth lines; and the second shelf 45 beyond the fourth line. The blank is folded about ~he first, second, third and f~ur~h fold lines in stepwise fashion to arrive at ~he Fig. 3 configuration for the body 51.
An upper reinforcing flange 69 is folded about the first line 61 into parallel relationship with the first shelf 43. The flange 69 xeinforces the wall 40 against defelction from a load applied to the shelves as well as providing a shelf for large food tray receipt, if desired.
The gussets 55 comprise an exten~ion of the first shelf beyond the ends 57, 59. The degree of extension lengthwise of the body 51 beyond the ends 57, 59, which represents the length of the gusset on the formed slider, is a matter of choice. Pxeferably, to maximize support and minimize the amount of material, the gusset height is equal to the width of the panel 47 between the third and fourth fold lines. It can be seen most clearly in Fig. 5 that, with the gusset bent downwardly and perpendicular to the plane of the first shelf 43, the gusset edges 71, ~ 73 align closely with the upright face 75 of the panel 47 and the upright wall surface 42 on the upright.
Consequently, downward bending of the shelf 43 is prohibited by the gusset bearing on the surface 42. At the same time, downward deflection of the second shelf 45 ~5 is arrested upon the offset surface 75 encountering the edge 71 of the gusset.
A desirable feature of the invention is ~hat a rugged slider can be formed from a thin gauge material without welding or using fasteners. The formation of the slider involves simply stamping a blank and folding the blank in a prescribed manner.
The mounting tabs 53 are used to anchor the sliders to the uprights. Each mounting tab comprises an elongate $~.
body 77 having a leading edge or nose 79 and a trailin~
edge 81. The vertical wall 40 is Pxtended beyond the ends 57, 59 of the blank to define a stem 83 which defines a T-shape with the body and spaces the t~b body 77 from the er)ds 57, 59 of the rectangular blank body 51.
To assemble the slider, the slider is dispo~ed at an angle with respec~ to the upright 30 as indicated in Fi~.
4. The rounded nose 79 of each tab is introduced to a slo~ and ex~ended until the upper edge 83 of the slot abuts the juncture of the stem and the leading portion 85 of the body 77. The entire slider is pivoted about the point of abutment in the direction of the arrow 87 in .
Fig. 4 to direct the trailing edge 81 of the body 77 ~ehind the inside surface 89 of the upright, at which point the surface 92 of the face 40 facially abuts the wall 42 of the upright. The slider is locked by dropping the slider downwardly to its Fig. 5 position. In this position, the wall 95 of the upright is captured closely between the wall 92 of the wall 40 and the mounting tab body 77.
The slider is positively captured because the mounting tabs cannot be removed without tilting the slider away from the uprights. Because the weight of the loaded trays bears the sliders toward their locked ~5 position, the likelihood of inadvertently freeing the ~liders is reduced.
The foregoing detailed description was made for purposes of demonstratin~ the structure and operation of the invention, with no unnecessary limitations to be understood therefrom.
