[0011] An embodiment of the present invention will be described with reference to the drawings. First, the structure of a backrest cover 1 according to one embodiment of the present invention will be described with reference to FIGS. Fig. 1 is a front view of the backrest cover 1. Fig. 2 is a rear view of the backrest cover 1. Fig. 3 is a view in which Fig. 2 is turned upside down.

[0012] As shown in FIGS. 1 to 3, the backrest cover 1 includes a sheet-like substrate 10 that is a first sheet material, a first pocket 12 provided at one end (lower side in FIGS. 1 and 2) of a first surface (surface shown in FIG. 1) of the substrate 10, and a second pocket 22 provided at the other end (upper side in FIGS. 1 and 2) of a second surface (surface shown in FIGS. 2 and 3) opposite the first surface of the substrate 10. The opening of the first pocket 12 is at the other end of the substrate 10, and the opening of the second pocket 22 is at one end of the substrate 10. In other words, the first pocket 12 and the second pocket 22 are disposed approximately point-symmetrically with respect to the center of the substrate 10. In this example, the substrate 10 is made of fabric.

[0013] The first pocket 12 is formed by the base material 10 and a first front cloth 11, which is a second sheet material facing the base material 10 and sewn to the base material 10. The first front cloth 11 has a longer length in the width direction perpendicular to the depth direction (vertical direction in the figure) of the first pocket 12 near the opening of the first pocket 12 than the base material 10. Therefore, the opening of the first pocket 12 formed between the first front cloth 11 and the base material 10 can be opened relatively wide.

[0014] Additionally, at the edge of the first front cloth 11 on the opening side, a string hole 13 is provided by folding back and sewing the cloth to form a tunnel, and a tightening string 14 is passed through the inside of the string hole 13. This tightening string 14 allows the opening of the first pocket 12 to be tightened and narrowed as desired. At the edge of the first front cloth 11 on the bottom 12a side of the first pocket 12, a pleat 15 is provided to compensate for the difference in width with the base material 10. The bottom 12a of the first pocket 12 is generally linear, and the corners 12b have a small radius of curvature. Overall, the first pocket 12 is formed in a generally rectangular shape.

[0015] The second pocket 22 has the same structure as the first pocket 12 except for the shape of the bottom 22a. That is, the second pocket 22 is formed by the base material 10 and a second front cloth 21, which is a second sheet material facing the base material 10 and sewn to the base material 10. The second front cloth 21 also has a longer width, perpendicular to the depth direction (vertical direction in the figure) of the second pocket 22, near the opening of the second pocket 22 than the base material 10. Therefore, the opening of the second pocket 22 formed between the second front cloth 21 and the base material 10 can also be opened relatively wide. Pleats 25 are provided at the end of the second front cloth 21 on the side of the bottom 22a of the second pocket 22 to compensate for the difference in width with the base material 10.

[0016] In addition, a string hole 23 is provided at the end of the second front cloth 21 on the opening side, and a tightening string 24 is passed through the string hole 23. The tightening string 24 can be used to tighten and narrow the opening of the second pocket 22 as desired. At the bottom 22a of the second pocket 22, the radius of curvature of the corner 22b is larger than at the corner 12b of the first pocket 12. Therefore, the bottom 22a has a curved shape that protrudes toward the end of the substrate 10 as a whole.

[0017] The first pocket 12 and the second pocket 22 have approximately the same depth but different shapes of the bottoms 12a, 22a. The difference in shape between the bottoms 12a, 22a is mainly due to the difference in the roundness of the corners 12b, 22b. Moreover, the first pocket 12 and the second pocket 22 are provided so as to partially overlap on the front and back sides when the base material 10 is viewed in an unfolded state.

[0018] This backrest cover 1 is used by hanging it over a chair in the orientation shown in Figure 1 or 3, with the backrest stored in the pocket at the back of the figure, and the base material 10 hanging down behind the back of the backrest. In this way, the pocket at the front of the figure can be used as a storage space for storing luggage. In the state shown in Fig. 1, the backrest can be stored in the second pocket 22, and the first pocket 12 can be used as a storage compartment. In the state shown in Fig. 3, the backrest can be stored in the first pocket 12, and the second pocket 22 can be used as a storage compartment.

[0019] It is advisable to store the backrest in the pocket whose shape of the top end of the backrest matches the shape of the bottom of the pocket. Since the first pocket 12 and the second pocket 22 have approximately the same depth, either of the two pockets can be hung on the back of a chair with the same feel, while the other pocket can be used as a storage area.

[0020] The backrest cover 1 as described above can be made entirely of cloth except for the drawstrings 14, 24. However, the material is not limited to this. Any sheet-like material, such as resin or paper, can be used. It is not necessary to construct the entire cover from a uniform material. As long as the components corresponding to the base material 10, first front cloth 11, and second front cloth 21 have an overall sheet-like outline, all or part of them may be mesh-like. The mesh should be fine enough to prevent baggage from falling through the gaps when placing it in the first pocket 12 or second pocket 22, as described below. The base material 10, first front cloth 11, and second front cloth 21 may each be made from a different material or have a different mesh size.

[0021] Next, the method of use and effects of the backrest cover 1 will be described with reference to FIGS. Figures 4, 6, 8, and 10 show a first example of use in which the backrest cover 1 is placed on a folding pipe chair 30 with a relatively rounded upper end of the backrest. Figure 4 is a perspective view, Figure 6 is a rear view, Figure 8 is a side view, and Figure 10 is a side view showing a person sitting on the chair from the state shown in Figure 8. Figures 5, 7, 9, and 11 show a second usage example in which backrest cover 1 is placed on stacking chair 40, which has a relatively angular upper end of the backrest. Figure 5 is a perspective view, Figure 7 is a rear view, Figure 9 is a side view, and Figure 11 is a side view showing a person sitting in the chair from the state shown in Figure 9.

[0022] As shown in these figures, in the first usage example, the backrest of a pipe chair 30 with a relatively rounded upper end is accommodated in the second pocket 22 with a curved bottom 22a with rounded corners, and the backrest cover 1 is used. In the second usage example, the backrest of a stacking chair 40 with a relatively angular upper end is accommodated in the first pocket 12 with a generally straight bottom 12a, and the backrest cover 1 is used.

[0023] The first pocket 12 and the second pocket 22 of the backrest cover 1 are adapted to the size of the backrest of a typical pipe chair 30 or stacking chair 40 used in event venues, conference rooms, etc. In this way, backrest cover 1 can be hung on a chair so that the back of the chair is stored in the pocket of the two pockets 12, 22 whose bottom 12a, 22a has a shape closest to the shape of the top end of the backrest, and by hanging base material 10 behind the backrest, it is possible to add a good-looking and stable storage space to chairs of a wide shape. Of course, the pocket on the side that stores the backrest also functions as a cover for the backrest, and can be used to prevent dirt from transferring, provide privacy, protect the seated person's clothes and the chair, etc.

[0024] If both pockets were generally straight-lined like first pocket 12, the pocket containing the back of pipe chair 30 would have excess space at the corners, causing it to hang down, making it difficult to move the chair when grabbing the back. Furthermore, if the pocket were to move easily relative to the back, and if the balance of the contents stored in the storage compartment were to be poor or if the back was to be moved by hand, a lateral force, as shown by arrow A in Figure 4, were to be applied to the back cover, the position of back cover 1 would likely shift, causing the balance of pipe chair 30 to deteriorate. Also, from an aesthetic standpoint, excess space hanging down at the corners is undesirable.

[0025] Furthermore, if both pockets have curved bottoms like the second pocket 22, when the backrest of the stacking chair 40 is placed in the pocket, the corners of the backrest may interfere with the corners of the pocket's bottom, preventing the backrest from being placed deep enough in the pocket. While placing the backrest deep in the pocket securely fixes the backrest cover 1 to the chair, preventing it from coming off, this fixation is weakened if the backrest is not placed deep enough. Furthermore, the bottom of the pocket may be left over, making it difficult to move the chair, such as by grabbing the backrest. Furthermore, from the perspectives of balance and aesthetics, the same problems as those described above when both pockets have roughly straight bottoms are anticipated.

[0026] However, by making the shape of the bottom, particularly the roundness of the corners, different between the first pocket 12 and the second pocket 22, the backrest cover 1 can be made to fit a wide range of backrest shapes, as shown in Figures 4 to 11, thereby eliminating the above-mentioned problems and improving convenience.

[0027] Incidentally, in the folding pipe chair 30 shown in Fig. 4 etc., when a person is sitting, the front legs 31 and the rear legs 32 are not parallel to each other, but are positioned slightly apart near the seat surface 33. When storing the backrest in the second pocket 22, if one tries to store it deep near the seat surface 33 as shown in Fig. 4 etc., it is necessary to store both the front legs 31 and the rear legs 32 (the pipes extending from them) in the pocket (see Fig. 8). Therefore, it would be difficult to store the backrest deeply unless the opening of the second pocket 22 is formed to be somewhat wide. However, the backrest cover 1 of this embodiment is formed so that the opening of the second pocket 22 can be opened relatively wide, as described above, so this problem does not occur.

[0028] On the other hand, if the opening of the pocket is made large, it is easy to put things in it when used as a storage compartment, but it may also be easy for things to fall out or be easily taken out, which may make it easier for theft to occur. However, in this embodiment, the opening of the second pocket 22 can be tightened and narrowed as desired using the drawstring 24, so by tightening the opening after putting things in, it is possible to prevent the items from falling out or being stolen. Since the pockets 12 and 22 on both sides have this structure, the same effect can be obtained regardless of which pocket is used as a storage compartment (see FIGS. 6 and 7).

[0029] Furthermore, when considering the usage scenario shown in Figure 8, if there is not enough room in the width direction of the second front cloth 21 that constitutes the second pocket 22, i.e., the side that is hung on the front legs 31, when a certain amount of items are placed in the first pocket 12 and the base material 10 is pulled downward or backward, the second front cloth 21 will become taut between the two front legs 31. On the other hand, as shown in Figure 10, when a person 50 sits on a pipe chair 30, the position of the waist 51 is usually behind the front legs 31. If the second front cloth 21 is stretched between the two front legs 31, it may interfere with the waist 51 when the person sits down, causing discomfort and making it difficult to sit. This interference is thought to occur particularly strongly near the opening 22c of the second pocket 22.

[0030] Even if there is some leeway in the width direction of second front cloth 21, if the pocket opening can be expanded using a stretchable material such as rubber but is naturally kept closed, the same problem of interference with waist 51 will occur. Furthermore, in a chair where the entire backrest is curved forward, a similar interference problem will occur even without considering front legs 31.

[0031] However, in the backrest cover 1 of this embodiment, the width of the second front cloth 21 is made larger than the width of the base material 10, particularly near the opening 22c of the second pocket 22, and the opening 22c is tightened by the tightening string 24, so that it is not tightened in its natural state, so such interference problems do not occur. In this respect, too, the backrest cover 1 is highly convenient.

[0032] In addition, in the case of a stacking chair 40 shown in Figure 5, etc., in which the backrest rises from the rear legs 42 and only a generally flat backrest needs to be stored in the first pocket 12, there is no need to widen the opening 12c of the first pocket 12, as can be seen from Figure 11, and there is no problem of interference with the waist 51 of a person 50 sitting on the seat 43.

[0033] However, since there are various correspondences between the overall structure of a chair and the shape of the backrest (particularly the shape of the upper end), it is possible that the backrest of a pipe chair may have a shape that is suitable for being stored in the first pocket 12. In order to accommodate a wide range of chair shapes, it is preferable to have a structure in which the first front cloth 11 on the first pocket 12 side has some leeway in the length in the width direction, as with the second pocket 22 side, and to tighten the opening 12c with the tightening string 14. If the first front cloth 11 is left over at the opening 12c when the backrest is stored in the first pocket 12 and causes a lack of stability, the opening 12c can be tightened with the tightening string 14 to stabilize the fixation to the backrest.

[0034] As described above, the backrest cover 1 of this embodiment can add a convenient pocket for storing baggage to the back of chairs of various structures. Although the range of chairs that can be accommodated is naturally limited due to the size of the pocket, sufficient convenience can be achieved by configuring the backrest cover 1, especially the pocket, to fit the general sizes of pipe chairs and stacking chairs, which are simple chairs often used at events and meetings, for example, assuming use at events and meetings.

[0035] In this case, if the depths of the first pocket 12 and the second pocket 22 are approximately the same, then no matter which pocket the chair back is stored in and attached to the chair, a pocket that can be used to store baggage can be added with approximately the same feel. In this case, it is not essential to change the shape of the bottom of the two pockets as in the above-described embodiment. If the bottom shapes are the same, it may be difficult to attach the seat to a chair depending on the shape of the top end of the backrest. However, even in this case, there is a certain effect in improving convenience in that there is no need to distinguish between the pockets that accommodate the backrest and handling when attaching the seat is easy.

[0036] Furthermore, unlike the above-described embodiment, it is possible to make the pocket widths or opening sizes of the first pocket 12 and the second pocket 22 different, thereby expanding the range of chair shapes and sizes that can be accommodated.

[0037] This concludes the explanation of the embodiment, but in this invention, the materials and shapes of each part of the backrest cover, the configuration of the chair on which the backrest cover is placed, the size, shape and use of the pockets, etc. are not limited to those described in the embodiment. For example, instead of string-like members such as the tightening strings 14 and 24 in the above-described embodiment, a belt-like member having a certain width may be used to narrow the opening of the pocket. Furthermore, the configurations of the embodiments and their modifications described above can be implemented in any combination as long as they are not mutually contradictory, and only some of them can be taken out and implemented.
