TRAY FOR CABINETS, ESPECIALLY KITCHEN CABINETS, THAT CAN

BE TAKEN APART, ADJUSTABLE AT THE CORNERS AND ALSO IN RE_

LATION TO A LATERAL SLIDING DEVICE.

When trays, and the like, for cabinets, especially kitchen cabinets, sliding like drawers on side runners, are packed for transport or storage, their bulk, varying according to the height of the sides, is considerable.

The front piece- mounted on the forward end of the tray is often imperfectly placed in relation to the cabinet in which the tray is mounted.

The width of the space in which the tray is to be fitted may vary appreciably, partly on account of the different thicknesses of the sides of the cabinet, and there may be difficulties of adaption as a consequence. Subject of the invention is a tray to be mounted inside ca¬ binets, especially kitchen cabinets, the sides of the tray being removeable and the angles at which said sides are set being adjustable in relation to each other and to the dis¬ tance away from a lateral sliding device. Such a structure ensures minimum bulk for transport and stor¬ age and maximum adaptability during mounting to the dimen¬ sions of the cabinet.

The edges of the tray bottom are bent downwards and the low¬ er edges of the sides are bent inwards and upwards, and the tray is assembled by fitting together said bent edges of the bottom and sides.

Coinciding holes of the same size are bored through the low¬ er edges of the sides and in the edges of the bot om, fixing screws being passed through said coinciding holes to assem- ble bottom and sides together.

Adjacent sides are assembled by fitting threaded corner rods into the tube-like space created by the cylindrical curve given to the upper edges of the si-des. Towards each end of said upper edges recesses are made to receive threaded bushes which screw onto the angular corner rods. Rotation of the bush in one side therefore causes one of the ends of a threaded angle rod to slide axially thus va¬ rying the angle at which the adjacent side is set. By adjusting the .angle of the side on which the front piece is mounted, said.front piece.can be given the most suitable position in relation to the cabinet.

The distance between the sides of the tray and the lateral sliding device is adjusted by means of flat metal corner pieces . One end of said flat corner piece is fixed to the mobile guide of the device while the other end is fixed to the transversal side of the tray by means of round holes cor¬ responding to horizontal slots made in said side, and by means of screws that are screwed into the aforesaid holes, their heads creating adequate pressure on the slot edges.

The lateral sliding device comprises a fixed guide to be mounted on the cabinet composed of one side and two longi¬ tudinal ledges, one above and one, in an intermediate posi¬ tion, carrying an upward facing rail, and a tubular mobile guide whose cross section is rectangular, carrying a lower rail, said guide sliding between the two ledges of the fixed guide.

At the front end of the fixed guide a rolling means is noun ted projecting from a recess made for it in the intermediate ledge,allowing said rolling means to slide along the rail of the mobile guide.

At the bac end of the mobile guide a rolling means is mounted which slides between the upper ledge and the rail mounted on the intermediate ledge of the fixed guide.

The rolling means rotate on pins supported at the two ends on either side of said rolling means. Characteristics and purposes of the invention will be made ecen clearer by the following example of its execution il¬ lustrated by drawings.

The tray ( 10) is composed of a bottom ( I I) and of the trans¬ versal ( 12), ( 13) and longitudinal ( 14), ( 15) sides. The edges ( 16), ( 17) of the bottom are bent at 90° downward while the lower edges ( 18), ( 19) of the sides are bent up¬ wards U-wise. To assemble the tray the bottom edges are fitted into the space formed by the bent edges of the sides, as shown in Fig.3.

Having fitted these edges together, self-tapping screws(23) are screwed into the holes ( 20) , ( 2 I ) , ( 22) made to receive them on the edges of the bottom and sides of the tray.

The sides have their upper edges (30) curved to form cylin- drical seats:(3Dfor the threaded angle rods (32) and towards their ends have recesses (34) to take the threaded bushes (35) , (36) , (37) , (38) which screw on to the threaded ends(33) of said angle rods (32) When the bushes (35), (36) are rotated in one direction or the other, the angle of the transversal sides (12), (13) will vary in relation to the longitudinal sides (14), (15) while rotating the bushes (37)^*, (38) the angle of the long^'i_ tudinal sides (14), (15) will be varied. The frontal (40) is mounted on the side (12) by means of the screws (41) which pass through the vertical slots (43). Therefore, by rotating the bushes (35), (36), the position of the frontal (40) can be adjusted in relation to the cabinet in which the tray slides. Fig. 4 shows the side (45) of the cabinet on which is moun¬ ted a lateral sliding device (50) consisting of the fixed guide (51) applied to the side (45), and of the sliding guide (52) to which the tray is fixed. The fixed guide (51) comprises the upper ledge (53) and the intermediate ledge (54) with rail (55).

Structure of the sliding guide (52) is tubular of a rec¬ tangular cross section with an upper ledge (56) and a lower rail (57). The ledge (61) for the rolling means (62), Figs.4 and 6, is mounted by means of the pins (60) to the lower side of the guide (51).

Said rolling means revolves on the pin (63) fixed aC one end (64) to the ledge (61) referred to, and at the other end (65) on the side of the fixed guide projecting, above the ledge (54),^* from a recess made to allow the rail (57) of the mobile guide (52) to slide. At the back of the mobile guide (52) (Figs. 4 and 5) a recess (66) is made for the rolling means (67). Said rolling means rotates on the pins (68), (69) support¬ ed by the two side pieces (70), (71), and can roll along the rail (55) of the fixed guide (51).

On the front of said guide the flat corner piece (72) with the pair (73) of holes is mounted by means of pins (76) and, at the back, the flat corner piece (74) with pair of holes (75) is mounted by means of pins (77). ^■ In the transversal sides ( 12), ( 13) of the tray there are horizontal slots (80) , ( 81 ) , ( 82 ) , ( 83) through which screws, not shown for simplicity in the figures, are passed and fixed in the pairs (73) and (75) of holes made in the above mentioned flat corner pieces (72), (74). When said screws are tightened, their heads press against the edges of the slots and firmly hold the tray. By means of said slots, the distance between the lateral sliding device (50) and the tray ( 10) can be adjusted and adapted to suit the width of its accommodation in the ca- binet (45). Advantages

Minimum space occupied by the tray in transport and storage. A perfect position for the frontal piece in relation to the cabinet . 'Maximum sliding smoothness for the tray.

Possibility of adapting the tray to the actual space avail_ able for it in the cabinet.
