Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bundling aid for paper stacks, which is used for binding a stack of paper stacks, for example, a number of newspapers or magazines, with a string.

Unnecessary used paper such as newspapers and magazines that have been read are stacked flat, tied with a string, and disposed of or sent to a collection route. By the way, since the work of binding a large number of flatly stacked papers (hereinafter referred to as a paper stack) with a string while keeping them from collapsing is complicated, various binding aids have been conventionally proposed to facilitate the binding work. ing.

For example, there is known a stocker-type binding aid capable of containing a paper stack and binding the paper stack while the paper stack is stored. This type of binding aid has various structures, but generally has the following configuration. In other words, a box-shaped space for accommodating the stack of paper sheets is defined inside by constituent elements such as the frame and the pillars. In addition, a space on the bottom side in which a string can be brought into cross-shaped contact with the bottom surface of the lowest sheet of paper stored in the storage space, and a string passed through the space on the bottom side are attached to the four side surfaces of the paper stack. A space on the side surface is provided so that it can be brought into contact along the vertical direction. By using the space on the bottom side and the side side to run the string around, the paper laminate in the accommodation space can be cross-tied and bound (for example, Patent Document 1, 2nd prize).

On the other hand, there has also been proposed a binding aid that binds a string that binds a paper laminate and that is disposed of together with the paper laminate and the string. For example, in Patent Document 3, a stopper plate is formed with a hole in the center and a pair of grooves for string engagement is formed on the outer peripheral edge of the stopper plate. After passing the paper stack through a pair of grooves for securing the string, the string is tightly bound so as not to loosen, thereby maintaining the bundled state of the paper stack.

The above-mentioned stocker-type binding aid has the advantage of being able to bind without collapsing the paper stack, but since it is a cubic object, it takes up a large space and becomes an obstacle when not in use. has the drawback of Moreover, since the structure is complicated and the number of parts is large, there is also a problem that it tends to be expensive.

On the other hand, the one described in Patent Document 3 has a small size and a simple configuration, and is superior to the stocker type in terms of storability when not in use and price. However, since they are disposable, it is necessary to prepare a large number of them, which poses the problem of troublesome storage and management. In addition, since it is simply tied up with a string, in order to bind the paper stack with a string so that it does not collapse, a stocker for storing the paper stack (Patent Document 3 describes a used paper storage box) ) arises.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. An object of the present invention is to provide a bundling aid for paper laminates which is inexpensive due to its simple structure.

A bundling aid for paper stacks according to the present invention comprises: a plurality of rod-shaped members; the plurality of rod-shaped members arranged in the form of a mounting table that is open in a plane on which the paper stack can be placed; and a connecting shaft provided on each of the plurality of rod-shaped members so that when the plurality of rod-shaped members are installed on the installation surface in the form of the mounting table, the installation surface and the plurality of and a leg that provides a space through which a string for binding the paper laminate is passed between the rod-shaped members of the plurality of rod-shaped members, and the plurality of rod-shaped members are provided on the upper surface of the mounting table when in the form of the mounting table. each of which has an upper surface portion that constitutes a and is perpendicular to the same plane so that the upper surface portion can be displaced between the mounting table form and the rod-shaped closed rod form while the upper surface parts are in the same plane. It is characterized by being relatively rotatable around the connecting shaft .

The binding aid according to the present invention is used as follows. First, a plurality of rod-shaped members are opened to form a mounting table, which is mounted on a mounting surface such as a floor via legs, and a paper laminate is mounted on the upper surface. Next, the paper stack is bound by, for example, cross binding with the string while passing the string through the space provided between the installation surface and each bar member. At this point, the binding aid is sandwiched between the paper stack and the string in the form of a mounting table, ie tied to the paper stack. Next, the paper stack is turned over together with the binding aid, and the binding aid, for example, is arranged on the upper side of the paper stack. Then, it is closed in the form of a bar and the binding aid is pulled out from between the paper laminate and the string. When removing the binding aid from between the paper stack and the string, if the leg interferes with the string and is difficult to remove, rotate the stick-shaped binding aid to the side to knock it down and remove the leg from the paper stack. If it is in a state along the surface of the laminate, it is possible to prevent the legs from interfering with the string, making it easier to pull out the binding aid.

According to the binding aid for paper stacks according to the present invention, by using it as described above, it is possible to bind with a string the paper stack placed on the binding aid in the form of a mounting table.
