1 Claim. (Cl. 220-19) This invention relates to trays, and more particularly to trays of the type employed for holding a group of articles and for use in connection with washing, rinsing and drying machines.
It is an object of the present invention to provide a tray construction adapted for use in standard washing, rinsing and drying machines and which includes removable and interchangeable support members.
It is another object of the present invention to provide a tray construction of the above type wherein the tray assemblies may be stacked vertically when not in use for greater portability and more compact storage.
Other objects of the present invention are to provide a tray construction bearing the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is easy to use and eificient in operation.
For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a perspective view of a frame and base member adapted for use in washing, rinsing and drying machines and having secured thereto an end and side wall construction;
Figure 2 is a perspective view of a removable supporting member adapted to be used with the device of Figure 1;
Figure 3 is a perspective view of a modified form of removable supporting member adapted to be used with.
the device of Figure 1;
Figure 4 is a vertical sectional view taken along the line 4-4 of Figure 1;
Figure 5 is a top plan view of a base member adapted to be used with the present invention;
Figure 6 is a side elevational view thereof;
Figure 7 is a top plan view of a modified form of base member adapted to be used with the present invention;
Figure 8 is a top plan view of a further modified form of base member adapted to be used with the present invention; and
Figure 9 is a side elevational view thereof.
Referring now more in detail to the drawing, wherein similar reference numerals identify corresponding parts throughout the several views, there is shown in Figures 1 and 4 a base member 10 adapted to be used in standard washing, rinsing and drying machines upon which is mounted a rectangular frame member 11 substantially as illustrated.
As shown in Figure 5 a plurality of longitudinally spaced, upstanding lugs 12 are suitably secured to the inner face of the vertical portion of the base member 10 and extend upwardly above the upper edge of the latter, the horizontal portion of base member 10 intermediate the lugs 12 being provided with the slots 13.
The frame member 11 of Figures 1 and 4 is provided with a lattice work connecting the sides of the frame 2,832,499 Patented Apr. 29, 1958 "ice member 11 and consisting of the rods 14 secured at opposite ends to the frame member 11 and to each other at their points of intersection, as shown in Figure 1.
Frame 11 includes a side and end wall assembly indicated generally at 15 which is formed from a series of superposed spaced framing wires 16 and 17, a lower framing wire 18 on which is superimposed a framing wire 19 and an upper framing wire 20 on which is superimposed a framing wire 21. The framing wires are bent into rectangular form and are of any suitable gauge, the bends of one wire aligning with the bends of each other wire and forming the respective corners within which are secured the corner posts 22. Secured against the inner face of each of the end and side walls thus formed is a series of upstanding loops 23, the closed upper ends of which extend above the uppermost framing wire 21. In termediate posts 24 arranged in pairs are similarly secured to the inner faces of the end and side walls, the posts 24 along with the loops 23 forming braces for said walls. Hook shaped members 26 are secured to the inner faces of the side walls, as shown in Figure 1. An inner framing wire 27 aligned laterally with the lowermost framing wire 18 (Fig. 4) is suitably secured inside the braces 24 and loops 23 in freely spaced relationship to the framing wire 18, the lugs 12 passing upwardly intermediate the framing wires 27 and 18, and being bent downwardly around the inner framing wire 27, whereby 'to secure the side and end wall assembly 15 to the base 10. The closed upper ends of the loops 23 are received within the slots 13.
Referring now particularly to Figure 2, there is shown a removable tray support indicated generally at 30 and including a lower farming wire 31 secured at its corners to an upper framing wire 32 by means of the corner posts 33 and the intermediate pairs of posts 34, substantially as illustrated. Upper rods 35 connect opposite sides of the upper framing wire 32 and are aligned vertically with lower rods 36 connecting the corresponding opposite sides of the lower endless wire 31 and dividing the removable support 30 into the compartments shown. The removable support member 30 may be inserted into the bottom and side and end wall assemblies of Figure l, with the bottom endless wire 31 thereof resting on the horizontal portions of the frame member 11 or it may be supported upon hook shaped members 26.
Referring now particularly to Figure 3, there is shown another removable support, indicated generally at 37, and including a framing Wire 38 having opposite sides thereof connected by a transverse rod 39. Laterally spaced, longitudinal rods 40 are connected to the other opposite sides of the frame member 38 to provide a plurality of compartments, the removable support 37 being adapted to be used with the bottom and end and side wall assemblies comprising frame 11 of Figure l, and supported therewithin. The removable supports 30 and 37 may be coated with suitable plastic, such as for example vinyl chloride to avoid scratching or breaking the articles to be washed which are supported thereon.
Referring now particularly to Figures 5 and 6, there is shown a modified form of base asembly, indicated generally at 10A and identical in construction with the base assembly 10. In other respects the base assembly shown in Figures 5 and 6 is the same as that shown in Figures 1 and 4, and like reference numerals identify like parts throughout the several views.
Referring now particularly to Figure 1, there is shown a still further modified form of the base assembly indicated generally at 10B wherein the horizontal portions of the base member are connected by the rods 41. The other opposite sides of the base member 108 are further connected by the rods 42, which are in turn connected to each other by the transverse rods 43, substantially as illustrated. In other respects, the bottom assembly shown in Figure 7 is the same as that shown in Figures 1 and 4 and like reference numerals identify like parts through out the several views. Referring now particularly to Figures 8 and 9, there is shown a still further modified form of base assembly 10C adapted to be used with the present invention and including the rods 44 suitably connected at their opposite ends to the horizontal portions of the base member 10C, substantially illustrated. Rods 45, arranged in pairs at opposite ends of the assembly, are similarly connected at opposite ends to the other sides of the base member 10C, each pair of rods 45 being in turn interconnected by means of the transverse rods 46. In other respects, the base assembly 10C is the same as that shown in Figures 1 and 4, and like reference nurnerals identify like parts throughout the several views. I
Thus, there has been provided a side and end wall assembly which may be easily and readily connected to the base assemblies, 10, 10A, 1% and 106 by means of the lugs 12 and inner framing wires 27, the choice of the base member being determined by the type of washing, rinsing and drying machine employed. It will also be readily apparent that the base and end and side wall construction resulting therefrom is adapted to be stacked, one on top of the other, with the upper ends of the loops 23 being received within the slots 13, permitting the structures to be more compactly transported and stored, when not in use. It should further be apparent that there have been provided removable supports 30 and ,37 which may be interchanged with the base and side and end wall constructions described and on which the articles to be washed, rinsed and dried are supported within the compartments contained therewithin. In mounting the base and frame assemblies to form a unit, upstanding lugs 12 are insertedbetween wires 18 and 27 as may be more clearly seen in Figures 1 and 4 and said lugs are then bent over wire 27 as is shown by the dotted lines in Figure 4. The base and frame assemblies are thus formed into a rigid'unit within which any combination of supporting traysrnay be inserted. Thus for example traysupport 37 may be positioned at the bottom of the frame supported upon rods 14 and tray support 30 may then be positioned upon hooks 26.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention, as defined by the appended claim.
What I claim as new and desire to protect by Letters Patent of the United States is:
