Description

FIELD OF THE INVENTION

The present invention relates to a hanging holder used for holding sheets of paper, which is hung to support rails provided at a hanging frame housed in a document storing cabinet or at edges of a drawer thereof.

BACKGROUND OF THE INVENTION

Conventionally, this kind of hanging holder comprises a holder body which folds double a material of a predetermined size to form an opening between the edges so as to insert sheets of paper through the opening and hold them in the holder body and a pair of flat support bars mounted on and along the edges, the support bars each supporting at both lengthwise ends thereof hooks through which the holder is suspended to the support rails. The hooks, which are integral with each support bar or separate therefrom and fixed thereto respectively, thereby creating the problem in that each holder interfereswith its transportation or storage and requires a large space therefor.

A file different from the hanging holder is disclosed in the Japanese Patent Publication Gazette NO. Sho 40-3,942, which comprises a front cover, a back cover and a spine, and pivotally mounts hooks onto the back cover near the spine in a manner of being projectable or retractable, the hooks, when in use, horizontally projecting andbeing hung to the support rails and, when out of use, retracting into the file.

The file is not principally used for hanging and merely mounts the hooks onto both lengthwise ends of the back cover near the spine respectively, whereby the file is unstable to hang and merely pivotally supported in a manner of projecting or retracting.and means is not provided to keep each hook in the projecting state.

Hence, there is a fear that the projecting hook falls down of itself to hinder the hanging work. Also, it is difficult to keep the hook in notprojecting condition, thereby creating the problem in that the hook unintentionally projects to hinder packing of the file or interferes with placement thereof on a hook shelf or carrying about the same.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a hanging holder which can reliably hold hooks each in the working position so as to be stably hung to support rails when in use, and in the housed position or retracted position when packed or carried about, thereby having no fear that the hook unintentionally projects when retracted, or uninten tionally swings when the holder is to be hung for use.

The present invention is advantageous in that hanging holder provided with a holder body having an opening through which sheets of paper are inserted and held in the body and a pair of support bars mounted on and along the edges of the opening is characterized in that at both lenthwise ends of each support bar are provided hooks each supported to be rotatable in the working position where it is directed lengthwise of the support bar and the retracted position where it is retracted at a side of the holder body with respect to the support bar, and between each hook and the support bar is provided holding means for holding each hook in the working position or the retracted position.

The present invention is advantageous in that the hanging holder is provided at both lengthwise ends of the edges of the upper opening at the holder body with cutouts into which the hooks held in the retracted position are received respectively.

The present invention is advantageous in that each hook is provided with a receiving recess into which each lengthwise end of the support bar is received, the receiving recess being provided with an engaging surface engageable with the upper surface of the lengthwise end at the support bar in the working position of the hooks.

4 - The present invention is characterized in that each hook is provided with a base supported to the support bar and a hooked portion, the base being provided with a pair of walls opposite to each other at an interval larger than a thickness of the support bar and a connecting wall for connecting the upper portions of the opposite walls, between each of the opposite walls and the connecting wall is provided a space downwardly open so as to receive therein the end of support bar, a shaft bore is provided at the end of the support bar inserted into the receiving space, and at one of the opposite walls is provided a shaft projecting therefrom into the receiving space and engageable with the shaft bore when the end of support bar is inserted into the space.

The hanging holder of the invention is advantageous in that the shaft is provided with a guide surface slanted from the front to the rear in the direction of inserting the support bar into the receiving space and toward the opposite wall on which no shaft is formed.

The present invention is further characterized in that the holding means comprises a projection provided at one of the opposite surfaces of each lengthwise end of the support bar and the hook and projecting toward the other of the opposite surfaces, and at the other of the opposite surfaces. are provided a first engaging portion engageable with the projection in the working position of the hook and a second 1 engaging position engageble with the projection in the retracted position of the same.

The hanging holder of the invention is advantageous in that each hook is provided with a receiving recess into which the lengthwise end of the support bar is received, the receiving recess having an engaging surface engageable with the upper surface at the lengthwise end of the support bar in the working position of the hook.

In the above-mentioned construction, since the holding means for holding the hook in the working position and retracted position is provided between the support bar and the hook, the hook, when in use or retracted, can exactly be prevented from unintentionally falling down or projecting. Accordingly, the hanging holder is easy to hang to the support rails and also easy to pack into a carton and the hooks do not interfere with placement of the holder onto a book shelf or carrying about the same.

The above and further objects and features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawings.

0 DETAILED DESCRIPTION OF THE INVENTION

Referring to Figs.1 and 2, an embodiment of a hanging holder A of the invention comprises a holer body 2 which is formed of a tough cardboard or a synthetic resin plate of a predetermined size and folded at the center into two so as to be of U-like shape in side view and have a bottom 1 and which is adapted to hold sheets of paper inserted into the holder bodv2hrough the upper opening thereof, a pair of flat support bars 3 mounted on and along the edges of the upper opening of the holder body 2, and four hooks 6 formed mainly of synthetic 7 resin and rotatably supported to both lengthwise ends of the support bars 3 respectively.

The edges of the opening at the holder body 2 are mainly folded back and fixed at the folded edges by bonding or the like to form bag-like portions 2a into which the support bars are inserted and fixed thereto by bonding or the like, thereby mounting the support bars to the holder body 2 respectively. At both the lengthwise ends of the edges of the upper opening at the holder body 2 are provided cutouts 2b into which the hooks 6 are retracted respectively.

Each support bar 3 is composed of a thin, narrow material of rigidity, such as meatl or resin,and projects at both ends to the exterior from the cutouts 2b at both the widthwise ends of holder body 2, a shaft bore 4 is provided at each projection, and both ends of support bar 3 are formed in ircular arc concentrical in the shaft bore. Meanwhile, each hook 6 is opposite to the projection of support bar 3 and rotatably supported thereto by means of a pin 5 inserted into the shaft bore 4 and comprises a base 8 supported to the support bar 3 and a hooked portion 9 engageable with a support rail R shown by the phantom line in Fig.1, the base 8, as shown in Fig.4, being provided with a receiving recess 61 for receiving therein the support bar 3, the recess 61 being provided with an engaging surface 61a engageable with the upper surface of the support bar 3 in the working position of the hook 6, thereby transferring a load on the hook 6 to the support bar 3.

Each hook 6 is rotatably supported to the support bar 3 in the working position ( in Figs.1 and 2) where the hook 6 orients lengthwise of the support bar 3 and in the retracted position where the hook 6 is retracted at the holder body 2 side with respect to the same and holding means for holding each hook 6 in the working position or the retracted position is provided between each hook 6 and each support bar 3.

The holding means comprises an engaging projection 10 provided at the surface of each lengthwise end of the support bar 3 opposite to the inner surface of the hook 6 and projecting thereto, and a first engaging portion 11 and a second engaging portion 12 which are provided at the surface ot hook 6 opposite to the support bar 3 and engageable with the projection 10 in the working position and the retracted position of the hook 6 respectively. In addition, the first and second engaging portions 11 and 12 both are provided on the rotating path equal in radial length around the axis of the pin 5.

Incidentally, in the aforesaid embodiment, the engaging projections 10 are provided at both the lengthwise ends of each support bar 3 and the engaging portions 11 and 12 composed mainly of engaging bores are provided at each hook 6, which may of course be provided vice versa.

Alternatively, each hook 3 may be supported to the 1 - 9 support bar 3 as shown in Figs.6 and 7, in which the hook 6 constitutes its base of a pair of opposite walls 62 and 63 opposite to each other at an interval larger than a thickness of the support bar 3 and a connecting wall 64 connecting the walls 62 and 63 at the upper portions thereof and forming at the inner surface an engaging surface 64a engageable with the upper surface of the support bar 3. Between the opposite walls 62 and 63 and the connecting wall 64 is provided a receiving space 65 downwardly open and for receiving therein the support bar 3, a shaft bore 31 is provided at each lengthwise end of support bar 3 to be inserted into the receiving space 65, and at one wall 62 of the opposite walls 62 and 63 is provided a shaft 66 projecting from the wall 62 into the receiving space 65 and engageable with the shaft bore 31.

Each hook 6 is formed of synthetic resin and can elastically deform the opposite walls 62 and 63 to broaden the interval therebetween, whereby the support bar 3 is inserted into the broadened space 65 between the walls 62 and 63 from the opening of the space 65 and the shaft 66 is f itted into the shaft bore 31 at the support bar 3. Hence, the hook 6 can rotatably be supported thereto more simply and repidly than using the pin 5 as shown in the first emebodiment.

Also, the shaft 66 may make its end face rectangular. to the axis thereof, but as shown in Fig. 7, a guide face 67may be provided, which is slanted at the end face from the front to the rear in the direction of inserting the support bar 3 into the receiving space 65 and toward the opposite wall 63 not provided with the shaft 66. In this case, even without broadening the interval between the opposite walls 62 and 63, the support bar 3 can merely be pushed into the space 65 to fit the shaft 66 into the shaft bore 31 while pushing the walls 62 and 63 away from each other to broaden the interval therebetween, thereby further readily supporting the hook 6 to the support bar 3.

Since the opposite walls 62 and 63 are restored by an elastically restoring force after the shaft 66 is fitted into the shaft bore 31, the hook 6 does not escape from the support bar 3 so far as both the walls 62 and 63 are not forcibly broadened therebetween.

In addition, when each hook 6 is molded in synthetic resin and integrally with the shaft 66 at the wall 62, the opposite wall 63 having no projection is provided with a through bore 68 of a shape corresponding to the shaft 66.

Next, explanation will be given on operation of the hanging holder constructed as the above-mentioned.

The hanging holder A of the present invention, when in use, is hung to support rails formed at the edges of a hanging frame or a drawer at a document storing cabinet. The, hooks 6 each project in the working position to engage the first engaging portion 11 with the engaging projection 10, 1 t 11 - thereby being exactly held in the working positions and readily and stably hung to the support rails respectively. Hence, there is no fear that the hook 6, when hung thereto, happens to fall down to deteriorate the work efficiency for hanging. Moreover, when the hook 6 is held in the working position, the engaging surface 61a of the receiving recess 61 at the hook 6 in the first embodiment and the engaging surface.64a of the connecting wall 64 in the second embodiment engage with the upper surface of the support bar 3 to thereby transfer a load on the hook 6 thereto. Hence, the weight of holder body 2 can be supported by the support bar 3 of high rigidity.

On the other hand, when the hanging holder is not used in hanging, carried about, o: - packed in the container for transportation, the hook 6 is retracted so that the hanger holder is not bulky. In this case, the second engaging portion 12 engages with the projection 10 to hold the hook 6 in the retracted'position, and there is no fear that the hook 6 unintentionally projects to interfere with the carrying-about or the packing of the holder.

As seen from the above, in the present invention, each hook 6 can be turned in the working position and the re- tracted position and hung to the support rail R so as not to interfere with the carrying about or the packing of the holder, and moreover can exactly be held by the holding means - 12 in the working position and the retracted position. Hence, the hook 6, when hung for use, does not fall down of itself to thereby save trouble such that a user hangs the hooks 6while holding them by his both hands, resulting in easy hang ing work. The hook 6, when the hanging holder is carried about, packed in the container, or placed on the book shelf, are held in the retracted position, thereby being exactly prevented from unintentionally projecting, resulting in easy packing work. Also, the hooks 6 each can be rotated to select the working position and retracted position, thereby being advantageous in simple and quick handling of the same.

Although several,tmbodiments have been described, they are merely exemplary of the invention and not to be constructed as limiting, the invent-i',)n being defined solely by the appended claims.
