Abstract

A material-holding device composed of a plurality of veticallyspaced horizontal shelves that are connected at opposite transversely-spaced ends by front and rear parallel links so that the shelves may swing from direct vertically aligned positions with respect to one another to fore-and-aft offset positions with respect to one another. Supported on one of the upper shelves are a pair of depending legs or supports that have lower ends that engage a table top or other surface so as to support the entire device when the shelves are in their fore-and-aft offset positions. The legs or supports are fixed to an upper shelf and are received in notches opening rearwardly in the shelves beneath the upper one. The containers mounted on the shelves have lids that swing about on a transverse horizontal axis and are forced into and are retained in their closed positions when the shelves are moved into their vertically aligned positions.

INVENTOR. ROY E. TANNER MATERIAL-HOLDING DEVICE BACKGROUND OF THE INVENTION This invention relates to a material-holding device that has a plurality of horizontal shelves therein that are movable relative to one another between fore-and-aft offset positions and vertically aligned positions. Mounted on the shelves are material retaining structures'that receive material overhead and consequently when the shelves are in their vertically aligned positions, material cannot be placed on or removed from these structures.

Heretofore, it has been known to provide spool-supporting pins that are mounted on parallel shelves so that thread could be removed from the spool when the shelves are open. However, in many instances it is desirable to place items in containers that are mounted on shelves and it is also desirable to force the containers into a closed position when they are not in use.

It is also desirable to place the containers on the shelves so that the entire container may be removed when desired and again be replaced on the shelves when there is nofurther need for it.

SUMMARY OF THE INVENTION lower ends will contact and engage a table top or other surface to support the entire device whenthe shelves are in their extended positions.

It is a further object of the present invention to provide materialcontaining devices on the respective shelves v,that' enclose in part vertical pins or supporting spools and-in part containers with lower depending pin portions that are received in openings in the shelves.

The containers have lids that swing back 'on horizontal hinges and the height of the containers are such that the lids must be closed when the shelves are in vertical alignment and the only time the lids may be opened is when the shelves are in fore-and-aft offset relationship to one another.

DESCRIPTION OF THE PREFERRED EMBODIMENT The material-holding device is composed of a plurality of vertically-spaced horizontal and parallel shelves 10. Each shelf is transversely elongated and has a front edge 11, a rear edge 12 and oppositely transverselyspaced ends l3, 14. A pair of parallel links or bars l5, l6 and 17, 18 connect to opposite ends of the shelves 10 by transverse pivot pins such as at 19. The parallel links l5, l6 and 17, 18 permit the shelves movement between a position shown in FIG. 4 in which the shelves 10 are vertically aligned in a position as shown in FIG. 2 in which the shelves 10 are fore-andaft offset from one another.

A pair of transversely-spaced parallel and vertically extending openings not shown are provided in the second shelf from the top adjacent the shelfs rear edge. The upper ends of a pair of stands or

support elements

21, 22 are retained or fixed in the openings and have lower ends that are adapted to engage the surface of a table for supporting the rear portion of the device when it is as shown in FIG. 2. Referring specifically to FIG. 2, it will be noted that the height of the supports 22 is such that the shelves 10 are horizontal and the lower edge of the link 17 engages the upper edge of link 18 thereby offering stability to the entire unit when it is in such a position. The middle shelf 10 is provided with a pair of notches or

recesses

23, 24 that open from the rear edge 12 of the shelf 10'. The notch 23 is angled from that edge so that in placing the pin 21 through the inlet 25 of that notch 23, it must be bent or distorted from the direct vertical. Upon it moving through the inlet 25, the resilient element 21. will snap into the base of thenotch 23 and will operate to lock, when so disposed, the entire device in its vertical position as shown in FIG. 4.

The notch 24 opens directly forwardly from the edge 12 although it should be understood that a similar angled notch could be provided for the support 22. Also, the supports 21, 22 engage the rear edges when in the

notches

23, 24 so as to prevent forward tilting movement of the upper shelves to a position in which the shelves are vertically aligned. Thus, the

supports

21, 22 not only serve as a support for the device when the shelves are in their open position, but also serve as a locking device to prevent accidental movement of the device out of its closed position as shown in FIG. 4.

There is provided on the second highest shelf 10 a pair of material-

retaining structures

27, 28. The

structures

27, 28 are in the form of material containers having lower upwardly opening bases or'boxes 29 and lids 30 that are hinged at 31 to the upper rear edge of the lower box 29 and to the rear edge of the lid 30. The lid 30 has upper laterally extending surfaces 32 inclined downwardly from front to rear so that as the next highest shelf 10 moves from its open position to its closed position, the front edge 11 thereof will pass closely adjacent the surface 32. When the shelves 10 are in their closed position as shown in FIG. 4, the undersurface of the shelf 10 above the lid 30 will be closely adjacent the upper forward point 33 of the lid. This will prevent accidental opening of the lid 30. However, when the shelves are in their open position as shown in FIG. 2, the lid 30 may be hinged open and rest against the forward edge of the next highest shelf 10, such being shown in dotted representation in FIG. 2.

Referring now to FIG. 5, the container 27 is retained on its respective shelf by a series of depending lugs or pins 34 which are integral with the floor or base 35 of the container. Provided in the shelf 10 are vertical openings 35 for receiving the pins or lugs 34. Provided on each lug 34 is an annular collar 36 which frictionally engages the internal surfaces of the openings 35. The

containers

27, 28 may therefore be mounted in the respective shelf 10 by pressing the lugs 34 in the openings 35 and it has a snap-in type of feel when it is so inserted.

The middle shelf 10 is provided with a series of transversely-spaced openings centrally located between the front and rear edges ll, 12 that receive vertical pins 37 that may be glued or otherwise held in the shelf 10'. If the entire device is made of plastic, the pins 37 may be integral with the respective shelf 10'. The pins 37 serve as material-retaining structures for spools 38, or other products that can be retained on pins. As shown in FIG. 4, the height of the pins 37 are such that when the shelves 10 are in vertically aligned positions, it will be impossible to remove the spool from the pin 37.

Also provided on the rear upper edge of the upper shelf 10 is a hanger element 40 which will permit the entire device to be hung on a wall when it is desired to store it. Such hanger device 40 is used on smaller devices.
