FILING RACK FOR HOLDING Thomas Martin, Pittsburgh, Pa. Application May 18, 1953, Serial No. 355,618

3 Claims. (Cl. 24252) helical spring 22 thereon, one end 23 of which bears against the rear face 5 of the strip 1 and the other end 24 bears against the operating portion of the clamp 11 to force its clamping edge against the face 5 of the strip.

When the abutment 9 of the key 10 is placed in the seat 8 between the flange 7 and the rolled edge 6, the stem 14 can be placed against the operating end 25 of the clamp when the latter is depressed toward the surface 5 of the strip. This creates an over dead center position of the key relative to its seated abutment 9 causing the latter to hold the clamp 11 in its open position as illustrated in Fig. 4. The end 26 of the key 10 need only beraised to allow the abutment 9 to move around the are 6 and thus permit the operating end of the clamp to be released from its'locked position. During the lockby pressing one or more clamps by the pressure of one or more clamps to bind the sheets by friction and eliminate the need to perforate the same and also the provision of an open flange along the other edge of the strip to also stiffen the same and provide a locking abutment for an over center locking key on this support for the binding strip in a rack.

Other objects and advantages appear hereinafter in the following description and claims.

The accompanying drawings show for the purpose of exemplification without limiting the invention or claims thereto certain practical embodiments illustrating the principles of this invention wherein:

Fig. 1 is a view in elevation of the front face of a file binder.

. Fig. 2 is an enlarged end view of the file binder shown in Fig. 1.

Fig. 3 is an enlarged perspective view of the file binder and key.

Fig. 4 is a sectional view showing the key holding a clamp on the file binder in its open position.

Fig. 5 is an enlarged perspective view illustrating the file binder about to be placed on a hanger.

Fig. 6 is a view illustrating a hanger in its extended position having a series of file binders supported thereon.

Fig. 7 is a view similar to Fig. 6 showing the hanger in its retracted position.

Referring to the drawings, the binder as illustrated is shown in Fig. 1 as a strip member 1 made of metal, plastic or other suitable material having one longitudinal edge 2 folded back on itself to form the continuous round bead 3 that extends longitudinally of the strip and forms the shoulder 4 adjacent the front face 5 of the strip.

The opposite longitudinal edge of the strip is likewise rolled toward its rear face 5 to form the hook or channel member 6 having an inturned flange 7 that defines 'a fulcrum seat 8. As illustrated in Fig. 4 the seat 8 is for the purpose of receiving the rounded abutment foot or end 9 on the key 10 which is employed to hold the clamp 11 in its open position as shown in Fig. 4. As illustrated in Fig. 3 the key 10 has a cylindrical bend or bight section 12 which bears against the inner arcuate surface 13 of the rolled edge 6 on the strip. The stem or standing portion 14 of the key provides a slight reversed. curve from the bight portion 12. as illustrated in Figs. 3 and 4.

The strip 1 has parallel spaced cars 17 formed from and struck out of the strip. A pair of oppositely disposed depending ears 20 are provided on the clamp member. The cars 17 and 20 are provided with aligned openings to receive the pivot rod 21 which passes through the same and has riveted heads on the ends thereof to prevent it from accidental removal. The pivot pin 21 has a ing and the unlocking-action of the key 10 against the operating end of the clamp, the curved bight portion 12 of the key rides over the surface of the operating end of the clamp allowing it to slowly recede from the rear surface 5 of the strip. 1

When the clamp is released as shown in Figs. 1 and 2, its clamping edge 27 engages the rear surface 5 of the strip 1 in spaced relation from the shoulder 4 formed by the bead 3. Since the hinge of the clamp is inwardly spaced from the clamping edge 27 the sheets or prints that are held by this binder may be slid under the open clamp until they engage against the cars 17 and 20 which function as stops limiting the upward insertion of the prints. When the keys release the clamps and allow their clamping edges 27 to exert pressure on the rearmost print, the prints in the stack so clamped are all required to fold over the bead 3 owing to the fact that the clamping edge 27 is spaced from the shoulder 4 formed by the head 3.

This curvature created in the prints increases the clamping action over that of any other similar type of clamp. The prints are required to bend over a bead or abutment and then pass down to the surface 5 of the strip through a reversed curve and under the clamping surface. Any pull on a print or sheet that is stored in this manner has a tendency to raise the clamp and thus apply a force against the spring pressure. This materially increases the clamping action Without increasing the spring pressure of the clamp or Without providing serrated or piercing or roughened surfaces that are supposed to increase the friction of the clamp.

The back face 28 of the strip 1 has a pair of curved spaced ears 30 for the purpose of holding a card as illustrated at 31 in Figs. 6 and'7 carrying indicia to indicate the class or character of prints in the particular binder.

The ends of each binder may be supported on the pins 32 projecting from the opposite arms 33 of the U shaped frame member 34. The ends of the arms 33 are attached to the pivot members 35, the other ends of which are secured to the panel member 36. A panel member 36 may be secured to the wall, desk or even a mobile rack. The sides of the frame member 34 may be supported by the hinged bracket members 37, one on each of the arms 33, which bracket may be broken intermediate of its ends for the purpose of allowing the arms 33 to swing to a vertical position as illustrated in Fig. 7.

When the U bar of the frame is pulled upwardly the brackets 37 may be locked in their extended position byan overcenter locking arrangement well known in the art, for the purpose of extending the frame as shown in Fig. 6. It is preferable that the brackets 37 prevent the frame 34 from rising to the horizontal position so as to atford an opportunity of reading each of the tabs 31when the frame is in its extended position as shown in Fig. 6 or when in its folded position as shown in Fig. 7. The

rows of inwardly projecting pins 32 in each of the arms 33 are mounted in pairs oppositely disposed from one another so as to providea hinged support for each binder at uniform distances from each other. This disstance permits the prints of each binder to be readily withdrawn and inserted when the frame is extended as shown in Fig. 6, but when the frameispivoted as shown in "Fig. 7 the binders pivot on thepins 32 and permit their prints to remain in the vertical position in close proximity to each other. When the frame is in the vertical or retracted position the prints ofone binder may readily be removed but it is more difiicult to reinsertthem. It isunderstood that the phraseology employed herein is for the purpose of description and not limitation, and it is not intended to limit the invention claimed herein beyond therequirements of the prior art.

I claim:

VI. A binder for holding sheets comprising a strip having front and back faces, one marginal edge ofsaid strip having a straight ridgerounded to said front face of said strip, a plurality of spaced clamp means carried on the front face of said strip, each clamp means having a spring biased movable clamp jaw the clamping edge of which is parallel with and spaced from said roundedridge to engage and bend sheets over said rounded ridge, a frame with opposed inwardly projecting pins, and a hook shaped fiange along the other marginal edge of said strip tordrop over said pins and hingedly support said binder on said frame and permit the'sheet'to pivotally hang uniformly from said frame.

2. The structure of claim 1 characterized in that said hook shaped flange has a curved portion with an inturned abutment to provide a seat, and a key having a bend terminating in an end to fit the seat with the key end engaging said abutment, and astern on said key lying against said clamp jaw to hold it inits open position.

3. The structure of claim 1 which also includes hinge means on said frame to hingedly support said frame on a wall to uniformly suspend the sheet from said frame and spaced from said wall.
