Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a binding device used for a sample book or the like for binding a mount or a catalog on which a sample such as a wallpaper is stuck. In particular, the present invention relates to a binding tool formed from a synthetic resin material.

[0002]

[Prior art]

 At the site of product manufacturing or planning, a sample book in which a mount group on which samples of various materials such as curtains and wallpapers are stuck is widely used. Due to the nature of the group of sheets to be bound, the size, weight, and thickness of such a sample book become large. And other problems arise. For this reason, the sample book usually uses a metal binding device capable of firmly and firmly binding the mount group.

FIGS. 15 and 16 show examples of a conventional sample book binding device. The binding device used in the sample book includes a metal base plate 1 including a bottom plate 15 fixed to the inner surface of a spine 50 of the cover paper 5 and side plates 16 and 16 standing upright from both edges thereof. The base plate 1 includes a binding member 20 formed by bending a metal round bar fitted into the curled portions 10, 10 formed at the edge of the side plate 16 in a U-shape. In this case, the binding pieces 21 of the binding hardware 20 are passed through the binding holes 40, 40 of the mounts 4, 4, which are the objects to be bound, and held there, while the shaft portions 22, 22 of the binding hardware 2 are held. Are press-fitted into the curls 10, 10, and after press-fitting, the curls 10, 10 around the binding hardware 20, 20 are caulked with a tool such as pliers to prevent the mats 4, 4 from falling off. Is firmly bound.

[0004] In recent years, the use of recycled resin in various products has been encouraged from the viewpoint of environmental issues and recycling, and the use of recycled resin has also been considered for binding devices of this sample book. However, in the above-mentioned conventional sample book, when the base plate 1 and the binding metal 20 formed of a metal plate and a metal round bar are made of the same size and made of synthetic resin, The strength of the member corresponding to the binding piece 21 of the binding member 20 is insufficient, and the weight of the board groups 4 and 4 acts as an impact load during handling, so that this member may be bent or broken.

It is possible to increase the diameter of the binding member 20 so as to withstand the impact load. In this case, however, the diameter is larger than the width of the binding hole 40 of the mount 4. Therefore, the existing mounts 4 and 4 cannot be bound.

[0006]

[Problems to be solved by the invention]

 The present invention relates to a base plate having a configuration in which the side plates stand upright from both side edges of a bottom plate fixed to the inner surface of the spine, and the base plate is fixed to the side plate by penetrating between the side plates in a bridging manner. In a sample book binding device composed of a binding rod, when the binding rod is formed of a synthetic resin material, it is an object of the present invention to improve the strength against an impact load during handling due to the weight of the backing sheet.

[0007]

[Means for Solving the Problems]

 * 1. The technical means of the present invention for solving the above-mentioned problem is as follows: “The binding rod is a synthetic resin having a length that is somewhat longer than that between the side plates having a vertically long rectangular cross section that can pass through the binding hole of the backing paper. A rod made of resin, and the rod is held by the penetrated portion of the side plate so that the vertical cross section stands upright with respect to the base plate. "

The above technical means operates as follows. According to the above-mentioned means, since the binding rod used in this binding device has a vertically long rectangular cross section, it has sufficient strength against a load in the vertical direction from the group of mounts penetrated and held by the binding rod. Usually, the sample book is often carried with a handle attached to the spine, so that the impact load is most likely to be applied to the binding rod when carrying the sample book. However, for the above reasons, the strength in such a usage mode is improved. .

Further, with respect to the load in the lateral direction of the cross section of the binding rod (the load in the direction parallel to the spine), the pressure applied to the binding rod is dispersed by the wide supporting end surface and the elasticity of the synthetic resin material is increased. As a result, the impact load is reduced. Such a usage state in which a load is applied is mainly when the sheet is placed on a table or stored in a bookshelf with the side adjacent to the binding side of the mount group facing downward. Therefore, it is possible to prevent the binding rod from being damaged by the load of the backing sheet group at the time of placement or storage due to the elastic deformation. This is true not only for the sample book, but also when used as a binding tool for other files.

[0010] Furthermore, since the cross-sectional shape of the binding bar is set so as to be able to penetrate a binding hole of a mount used in a sample book made of a conventional metal binding device, a mount having the same standard as that of the conventional can be used. Can be bound.

[Miscellaneous] * Item 2 In the item 1, the “the binding bar is a binding bar that penetrates from one side plate to the other side plate, and has a base portion that comes into contact with the one side plate in a push-in preventing state. A narrow neck portion is formed at the other end protruding from the other side plate, and a holding tool is provided on the other side plate to hold the neck in a detachable state so as to be detachable. The holding tool is an annular stopper that is externally fitted from the head on the distal end side of the neck for fixing the binding rod to the side plate and is removably engaged with the neck, and the head is the binding rod. The annular stopper has an inner peripheral shape having a short-diameter portion rotatable with respect to the neck and capable of engaging the neck in a frictionally engaged state. The annular stop has friction with the neck. The annular stopper is oriented so that the head of the binding rod penetrated through the side plate can be inserted (the long diameter portion of the inner peripheral shape matches the longitudinal direction of the head section). The binding rod can be locked to the side plate by being fitted to the outside, rotating by a predetermined angle at the outer peripheral position of the neck portion, and frictionally engaging the short diameter portion. The annular stopper and the neck can be removed by forcibly rotating the annular stopper to release the engagement. Therefore, the binding bar can be easily fixed to and removed from the side plate.

[0012] Further, in the case where engaging means capable of engaging and recessing with each other is provided on the inner peripheral surface of the annular stopper and the outer peripheral surface of the neck portion, the engaging means is engaged by the concave and convex fitting in addition to the frictional engagement force. Therefore, the engagement between the annular stopper and the neck becomes more reliable and stable.

[0013] * 3. In the paragraph (1), "the binding bar is a binding rod penetrating from one side plate to the other side plate, and has a base portion which comes into contact with the one side plate in a push-in preventing state, and The other end protruding from the side plate is formed with a narrow neck portion, and the other side plate is provided with a holder for detachably holding the neck portion in a detachable state. Is a locking plate formed with a locking hole engageable with the neck portion and slidably provided along the longitudinal direction of the side plate, wherein the locking hole is provided at a tip end side of the neck portion. An insertion hole through which the head can be inserted, and a notch formed in the sliding direction of the locking plate continuously with the insertion hole and shorter than the vertical length of the head but externally fitted to the neck. The head is inserted through the insertion hole of the locking hole. To match the neck, when the slide along this after locking plate in the longitudinal direction of the side plate, the neck portion is a head fitted into the notch is held in a state retaining this locking plate.

Here, in the case of “the locking plate is set to be longer than the entire area where the binding rods are provided and the locking holes are provided so as to fit the respective necks”, The necks protruding from the side plates are inserted into the respective insertion holes of the locking plate at one time, and from this state, the locking plate is slid in the longitudinal direction so that the notch is continuous with the insertion hole. Each of the binding rods can be locked to the side plate by fitting and holding the neck portion. For this reason, it is possible to lock a plurality of binding rods at a time, and thus it is easy to fix the binding rod to the base plate.

* 4. In the paragraph 1, the paragraph "The binding bar is a binding bar penetrating from one side plate to the other side plate, and has a base portion which comes into contact with the one side plate in a push-in blocking state, and The other end protruding from the side plate is formed with a narrow neck portion, and the other side plate is provided with a holding tool for holding the neck in a detachable state so as to be detachable. Is a locking plate made of an elastic material formed with a cutout portion through which the neck portion can be inserted and opened downward and slidably provided along the short side direction of the side plate. Is formed with a locking portion that elastically engages with the side plate or the neck portion in a retaining state. ” So that the neck of the binding bar passes through the notch of the stop plate By pushing the locking plate from above, the neck portion can be fixed to the side plate. In addition, since the locking plate is locked to the side plate or the neck in a locked state by the locking portion that elastically engages, the locking plate is moved by moving the locking plate up and down. A stop plate can be attached and can be removed.

Here, “the locking plate is set to be longer than the entire area where the binding bar is provided, and the locking portion is a locking portion that engages with the lower end of the cross section of each neck”. In this case, a plurality of binding rods can be locked to the side plate at once, which is simple and the locking plate does not fall off, so that the binding rod is securely fixed to the base plate.

* 5. In paragraphs 1, 2, 3, and 4, "a plurality of binding rods are connected in parallel at one end so as to have a predetermined interval from each other." By doing so, it is possible to perform the holding operation of the mount group through the binding rods and the operation of attaching the binding rods to the side plates at a time for a plurality of connected binding rods. Workability is good.

[0018]

[Effects of the Invention] The present invention has the following specific effects because of the above configuration. When carrying or handling this sample book, in a sample book in which the backing group is penetrated and held by a synthetic resin binding bar, the binding bar is not distorted or broken by the impact load due to the weight of the backing group. Strength is improved and it is hard to be damaged. Also, since the mount of the same standard as the conventional sample book can be bound, there is no need to change the mount standard.

Further, in addition to the above-described effects, in the invention described in item 2, it is easy to lock and remove the binding rod from the base plate. In the case of item 3, it is easy to fix the binding rod to the base plate. In the case of item 4, the fixing of the binding rod to the base plate is simple and reliable. In section 5, the workability of inserting the binding rods during sample book assembly and production is good.
