SUPPORT OF BENT STIFF WIRE FOR SUSPENDED FILES OR THE LIKE, REMOVABLY INSERTABLE INTO A FURNITURE DRAWER BACKGROUND OF THE INVENTION The present invention relates to a support of bent stiff wire for suspended files or the like, removably in sertable into a furniture drawer, comprising a lower frame and an upper frame mutually interconnected by means of a pair of mountings.
Supports of the above mentioned type are known. A first known support is provided with a substantially rectangular upper frame on the sides of which files or the like may be suspended, having supporting legs which may be stiff or having a certain resilience, for instance in order to fit the dimensions of the drawer in which the support may be inserted. This type of support is not sufficiently reliable in stiffness where the weight and the number of suspended files are large.
A second known support is provided with a substantially rectangular upper frame and lower frame which are firmly mutually interconnected by means of fixed attachements wherein both the frames and the attachements are made of stiff wire. This support cannot be folded and cannot be inserted into drawers which are not fully removable, unless it has at least one dimension which is markedly smaller than the corresponding dimension of the drawer.
SUMMARY OF THE INVENTION The present invention provides a support of bent stiff for suspended files or the like, which may be folded and collapsed so as to occupy a minimum volume, for instance in order to improve packing conditions.
In particular, in the support according to the inven tion, each mounting of the pair is rotatable on the upper frame, the rotation of said mountings being limited by stop means, the lower frame being provided with hook means suitable for holding said mountings in a substantially right angle position to said upper frame, against the stop means.
Such a support has the advantage that it can be inserted into and pulled out from a cabinet drawer so that the suspended files thereon may be transferred as a unit, for instance from the file cabinet to the working position or vice versa and, in addition, may be inserted into a drawer which is not fully opened or which cannot be fully opened while having the same bulk dimensions of the drawer.
The invention will be described in more detail, by way of example, with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a support according to the invention in the unfolded or opened position;
FIG. 2 shows the support of FIG. 1 in the folded position;
FIG. 3 shows schematically the manner in which the support is inserted into a cabinet drawer.
DETAILED DESCRIPTION OF THE INVENTION The support in accordance with the invention comprises an upper frame 1 (FIG. I), a pair of identical mountings 2 and a lower frame 3. All these elements 1, 2, 3 are constructed of substantially rigid wire or bars of round cross-section, of steel or other suitable material and may be coated with a layer of protective plastic material.
The upper frame 1 is made of two symmetrically superposed rectangular frame-like members 4 and 5 which are rendered mutually integral by welds at the cross points 14, the parallel sides having dimensions such that each side 6 and 7 of the frame-like member 4 is protruding out of the corresponding sides 8 and 9 of the frame-like member 5, while each side 10 and 11 of the frame-like member 5 protruds out of the corresponding sides 12 and 13 of the frame-like member 4.
The mountings 2 are substantially U-shaped and are rotatably mounted on the sides 8 and 9 of the framelike member 5 at points close to and internal of sides 12 and 13 of the frame-like member 4 by means of two loops 15, provided from the upper ends of the same mountings 2, so that they are able to rotate but not to slide along the frame-like member 5. Furthermore, each mounting 2 is provided on one side with a suitable bend 16, which is adjacent to the loop 15 and separated from the latter by the same distance existing between the side pairs 6, 8 or 7, 9, and, in addition, with a pair of substantially right angle bends l7 and 18, which create a projection 19 external with reference to the remaining support structure.
The lower frame 3 is substantially of rectangular shape and is provided with two U-shaped bends 20 at each end of the two sides 22 and 23. The bends 20 form two hooks adapted to be hooked by pairs on the transverse portions 24 of mountings 2.
A rod 25 provided with two semicircular bends 26 on its ends may be removably connected to the upper frame 1. The bends 26 rest slidably on sides 10 and 11 of the frame-like member 5 while rod 25 passes below sides 10 and 11 of frame-like member 4.
The support is generally stored folded as in FIG. 2 wherein the frame 3 is disconnected from the remainder. To mount the support, the mountings 2 are first rotated through 270 in the direction of the arrows until the bends 16 are stopped against the sides 6 and 7 of the frame-like member 4 (FIG. 1 The mountings 2 are at this time in the position shown in FIG. 1 by broken lines, wherein the transverse portions 24 are mutually separated by a distance which is larger than the length of the lower frame 3.
By urging mountings 2 more inwardly, the latter are resilently distorted to the position shown in FIG. 1 by dotand dash lines, wherein the transverse portions 24 are located at a distance which is shorter than the length of the frame 3. By abutting the lower frame against the transverse portions 24 of the mountings 2, and by releasing the same mountings, said transverse portions 24 engage the hooks 20 and remain hooked firmly thereon, due to the residual resilient force of the same mountings 2 which tends to rotate them further outwards against hooks 20.
When rod 25 is removed from the support, folders 27 (shown in FIG. 1 by a broken line) may be hung onto frame I by laying the lateral projections of said folders on sides 12 and 13 of the frame-like member 4. The folders may be also hung by laying them on the other two sides 8 and 9, whereby the support is adapted to receive folders of two different sizes, for instance, for documents of size A4 and A3. When the rod 25 is assembled on the support the folders may be hung by laying their lateral projections on the same rod 25 and on one or both sides 8 and 9 of the frame-like member 5. The support may in this way store folders of further different sizes.
The support represents, therefore, a compact filing device which may be easily inserted into or removed from, for instance, a drawer 27 (FIG. 3) of a cabinet 28 or a desk. In particular, the user interested in analyzing the folders lying in the support may remove from the drawer the whole support along with the folders.
Furthermore, the support can be inserted into a drawer 27 even though such drawer 27 has internal dimensions substantially equal to the over-all dimensions of the same support but which cannot be fully opened. To this end, it will be sufficient that the separation between bends 17 and 18 be larger than the separation between the internal wall 29 of the drawer 27 and the external wall 30 of the cabinet 28. In fact, it is sufficient to first insert the support by abutting and sliding a mounting 2 on wall 31 of the drawer 27 in the manner shown in FIG. 3, and to then slightly rotate the support and to displace it rightwards so that the projections 19 may be inserted.
It becomes apparent that a support of the described type, once inserted into a drawer that cannot be fully opened will not shift around, since its over-all dimensions are substantially equal to the internal ones of the drawer. In this way, the support is prevented from being shaken against the drawer walls when the drawer is opened or closed, as it might happen in the event that such support had, for instance, a parallelepiped shape and, therefore, of over-all dimensions smaller than the drawer to permit insertion where the drawer cannot be fully opened.
To fold the support it is sufficient to push mountings 2 (FIG. 1) in the direction of the arrows as long as the position displayed by a dot-dash line is obtained, to remove the lower frame 3 and then to rotate the mountings 2 through approximately 270 in the direction opposite the arrows. The mountings are thus laid inwards, substantially on the same plane of the frame 1 (FIG. 2), beneath which may also be located the lower frame 3. The support is therefore reduced to a substantially planar structure having minimum over-all dimensions.
What I claim is:
l. A support for removable insertion in furniture drawers for use with suspended files or the like, said support comprising:
a first rigid wire frame comprising two substantially rectangular elements and disposed in superposed relationship wherein one of said two elements has two opposite sides parallel to and protruding from two opposite sides of the other element at a predetermined distance therefrom;
a second rigid wire frame disposed below said first frame during use and having a substantially rectangular configuration and having two hooked portions at each end portion of two opposite sides thereof; and
a pair of rigid wire substantially U-shaped side members for mutually interconnecting said first and said second frames during use, said side members comprising means disposed on the closed end portion of each side member for engaging with one of said hooked portions and means disposed at the open end portion of each side member for engaging with said first wire frame to rotatably mount each side member on one of said two opposite sides of said one of said two elements for movement through substantially 270 and to hold each side member in a substantially right angle position with reference to said first wire frame.
2. A support according to claim 1, wherein said means disposed at the open end portion of each side member comprises a loop at each end portion of said open end portion and a first bend adjacent to each loop and spaced therefrom by said predetermined distance and cooperative with said two opposite sides of said other of said two elements to block the movement of the side members when in the substantially right angle position with said first wire frame.
3. Asupport according to claim 2, wherein each of said side members further comprises two second bends each disposed near one first bend and spaced from said loop to define a given length for said support to prevent said support from being shaken against said front and rear walls of a drawer having said given length in which it is inserted when the drawer is opened or closed, said second bend imparting to said support a dimension at the lower end shorter than the lenght at the upper end so that said support may be inserted into a drawer even when the drawer cannot be fully pulled out from the furniture.
