Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a binder device.

[0002]

[Technical background]

 In thick books, thick books, etc., the spine cover has a form called a so-called spine cover, which is bulged outward in an arc shape from the old days.

[0003]

[Prior art]

 Even in the case of binder metal fittings, when all the members were made of metal (made of sheet metal), the back-maru method was used.

[0004]

[Problems to be solved by the device]

 As described above, in the case where all the members are made of metal, the spine-ring structure is one of the essential requirements for operation and structure because of the elasticity that gives the binding claws.

However, in recent years, binding claws in binders, substrates that project the binding claws, that is, the operating body has been changed to synthetic resin with the passage of time, and elasticity is imparted to the substrate that acts to open and close these binding claws. Only the back plate is a metal plate that stops the old weather.

The operation pieces for opening and closing the binding claws are provided at both ends or one end in the longitudinal direction of the binder. Regardless of which type is used, when the opening operation is performed, the operation piece is extended on the extension side in the longitudinal direction of the main body. It is expected to release the binding claw by tilting it and pushing up the joint side of the two actuating bodies that are aligned with each other.

At this time, the operation piece tilted outwardly promotes the opening of the binding claw by a motion of pushing the actuating body upward from its lower surface by a lever action.

It is the back plate that receives the reaction force of the pivot fulcrum of the lever action that accompanies the tilting operation of the operation piece.

[0009] Even with the conventional binder made of synthetic resin for the operating body in which the binding claws of the main part are implanted and integrated, only the back plate obtains the elastic force necessary for opening and closing the operating body. For this purpose, a steel plate is used, and the inside of the back plate of the steel plate is used as the reaction force receiving the rotation fulcrum of the operation piece.

On the other hand, in the use of the binder, since the back plate of the conventional binder is a flat plate as described above, the angles on both sides of the binder are such that the connection angles with the front and back covers are right angles. Therefore, when a plurality of binders are stored in parallel in a shelf or a storage case, they can be stored neatly and can be stored in a refreshing appearance. When the individual is pulled out, the spine cover and the binder backboard are combined in a single plate, which makes it difficult to remove the object by catching it with a finger. Was not dissatisfied by the efforts of the individual handlers, but the frequency of multiple cases led to criticism that led to substantial work efficiency, and the beauty of the old-fashioned spine-maru method came to be considered. .

[0011] These back-round forms are not limited to binders, and have a great track record in the use of books for a long time since ancient times, and the advantage thereof is that demand for retro-fitting forms is increasing.

[0012] However, the binder used in the former spine production period and the current binder have been evolving structurally and in terms of material, and it is possible to return to the old configuration of the spine circle structure without taking these into consideration. There is a situation that cannot be done.

In view of this, the present invention has developed a new binder that is similar in appearance to the old-style spinner binder and does not exist in the conventional flat-back binder, so as to meet the demand for the spinner binder. It is a thing.

An operating body is used which has an opening / closing operation of the binding claw of the binder and a locking action of preventing the binding claw from being naturally opened unintentionally in the closed claw state.

This operating body has a substantially L-shaped side surface of a vertical opening / closing operating portion and a horizontal operating portion, and the formed outer angle serves as a fulcrum for levering, and this fulcrum is a metal. The fulcrum action can be expected by contacting the inner surface of a flat plate made of a plate.

Since the back plate of the metal plate serving as the fulcrum support is flat, it is possible to perform the above-mentioned configuration and operation.

However, since the present invention attempts to form the back circle by bulging the back plate outward in an arc, a fulcrum support is required when the configuration and operation of the operating body are the same as those described above. Since there is no portion for receiving a reaction force in the back plate at such a portion, the back plate structure and the operation body capable of coping with the action of these operation bodies have been developed.

[0018]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention has a plurality of binding claws arranged in parallel and joins a pair of inner sides of a main body whose tips can be separated and contacted with each other. Of the back plate made of an elastic material, which is pressed and attached to the outside of the main body, and hangs so as to become the movable pivot point of the main body.

Is engaged with a shaft portion that has the horizontal step portion, the distal end of the actuating portion is made engaged with the longitudinal end of the body.

According to a second invention, a plurality of binding claws are provided in parallel, and a pair of inner sides of the main body are joined so that their tips can be separated and contacted, and both outer sides are pressed together. In addition, in the back plate made of an elastic body that engages so as to become the movable pivot point of the main body, the bulging part with an arcuate cross section is bent outward along the entire length in the longitudinal direction, and Side portions are formed on both sides of the bulging portion 2, and the tips of the side portions are bent inward so as to face each other to form a main body locking portion. A horizontal step is formed between both sides of the bulge to form the back round back plate, and a pair of main bodies with several binding claws arranged in parallel are joined at their inner sides and The main body locking part of the spine back plate is hooked into the locking groove on the outer side of the body to be integrally formed, and the shaft part protruding from both sides of the operating body In addition to engaging with the horizontal step portion, the tip of the operating portion is engaged with the longitudinal end portion of the main body.

According to a third aspect of the present invention, there is provided a synthetic resin back round back plate, which is located at an intermediate position in the height direction of the bulging portion, the horizontal step portion, and both side surface portions from the direction of forming the bulging portion of the longitudinal end surface. Up to and including a restraint.

[Embodiment of device]

 The back-round back plate structure in the binder of the present invention is characterized in that the back plate bulges outward in an arc shape, and this back plate has binding claws like the back plate in the conventional binder. It is conditioned on the action of giving elasticity to the pair of main bodies.

That is, the material of the back plate is a steel plate having elasticity similar to the conventional back plate, or a synthetic resin which has not been used for the back plate of the conventional binder.

In the above-mentioned material, the back plate made of a steel plate is formed by pressing a steel plate having a uniform thickness into a required shape, and when a synthetic resin is used as a material, particularly in the width direction. The basic condition is that the required elastic force is obtained, and in order to obtain uniform elastic force over the entire length of the back plate, the back plate of the round spine is formed by the molding process without changing the specific position in the longitudinal direction.

The binder assembled with the back plate is a pair of two main bodies each having a plurality of arcuate binding claws arranged side by side on the upper surface thereof, but their inner members are butted and rotatably joined to each other. One side of the back plate made of an elastic material is attached to the outside with both sides being pivotally supported, and is held, and the main body and the back plate are assembled together.

In contrast to this, a vertical side piece serves as an opening / closing operation portion, and a side surface substantially L-shaped operation plate having a horizontal piece connected to the lower end thereof as an operation portion is formed, and an upper piece and a lower piece are formed at the tip of the operation portion. The inner and outer sides of the pair of main bodies are joined and inserted into the longitudinal ends of the pair of main bodies, and the opening / closing operation section of the operating body is rotated toward the extension of the main body in the longitudinal direction. Then, the outer angle of the lower end comes into contact with the inner surface of the back plate and acts as a fulcrum, the operating part pivots upward by levering, and the main body joint side maintains the joined state and resists the elastic force of the back plate. The binding ends of the binding claws planted in the main body are moved upward and are separated from each other so that they are in an open state.

The above-mentioned operation is described with reference to the embodiment in the case where the back plate is in a flat plate state. In this case, the pivotal support in the opening / closing operation part is applied to the lower end outer angle, and the flat part inside the back plate is supported. It is used for receiving reaction force.

The back round back plate 1 of the present invention is made of a steel plate having high elasticity as described above and is formed by press working, or is formed of a molded body of synthetic resin.

Regardless of which material is used, the back portion of the binder is provided with arcuate bulging portions 2 with most of its width facing outward over the entire length in the longitudinal direction, and both sides of the bulging portion 2 are provided. In this case, the side surface portions 4 and 4 are raised through the horizontal step portions 3 and 3, and the side edges connected to the side surface portions 4 and 4 are bent inward to form the main body locking portions 5 and 5. is there.
