The present invention relates to a binder used when binding a harness, a bag mouth, a field wire, an attraction string and the like.
As a binder of this type, for example, Patent Literature 1 discloses a plastic binding clip having a U-shape. This binding clip is configured such that a bound member can be bound by inserting the bound member between leg portions of the binding clip and bending the leg portions inward.
Patent Literature 1: JP-A-2004-10125
The above-described conventional binder is required to bind so tightly as to bite into the bound member in order to avoid displacement of the binder. Therefore, the bound member may be damaged by such tight binding.
Accordingly, a first object of the present invention is to provide a binder capable of performing stable binding while reducing displacement even if binding strength is not as strong as causing damage to a bound member.
Further, when used at a location where vibration occurs, the above-described conventional binder may cause damage by hitting other members or may be broken by an impact from other members.
Accordingly, a second object of the present invention is to provide a binder that is less likely to damage other members or be broken even when used at a location where vibration occurs.
The present invention has been made in view of the above-described problems, and provides a binder configured to bind a bound member by being struck out from a binding machine. The binder includes a substantially U-shaped base member that is plastically deformable, and a surface member that is provided on a surface of the base member.
The present invention is as described above, and the surface member is provided on the surface of the substantially U-shaped base member that is plastically deformable. According to such a configuration, as the surface member is provided on an inner surface and/or an outer surface of the base member, the effects such as stable binding and/or prevention of damage can be obtained.
For example, if the surface member is provided on the inner surface of the base member, the frictional resistance at a position in contact with the bound member can be improved, so that the holding force of the binder can be increased. Therefore, binding can be stably performed without displacement of the binder even if the binding strength is appropriate not as strong as causing damage to the bound member. Further, the effect of reducing impact when the binder hits other members can be expected.
If the surface member is provided on the outer surface of the base member, the buffering property at a position hitting other members can be improved. Therefore, even when the binder is used at a location where vibration occurs, damage to other members can be reduced and breakage is less likely to occur. Further, since the impact at hitting to other members is alleviated, the effect of preventing the binder from falling off by the impact can also be expected.
Embodiments of the present invention are described with reference to the drawings.
A binder 41 according to the present embodiment is used by being loaded into a binding machine 10 as shown in
As shown in
The motor accommodation portion 12 is provided at a rear portion of the binding machine 10, and a power source connection portion 12a which connects an external power source is provided at a rear end portion thereof. By receiving a voltage supply from the power source connection portion 12a, the binding machine 10 can perform various operations such as striking out the binder 41. A cord which connects to an AC [0] power source may be connected to the power source connection portion 12a, or a harness which connects to a rechargeable battery may be attached thereto. Although the binding machine 10 according to the present embodiment is of an electric type, the present invention is not limited thereto, and the binding machine 10 may be of a compressed air type. When the binding machine 10 is of the compressed air type, a connection portion which receives supply of compressed air may be provided instead of the power source connection portion 12a.
Although not shown in the drawings, a motor and a control portion are housed in the motor accommodation portion 12, so that driving of a driver 25 (described below) can be controlled.
The grip portion 13 is a portion to be gripped by a user when the binding machine 10 is used. The grip portion 13 is provided in an intermediate portion of the housing 11, and is formed in a constricted shape so as to be easily gripped by the user. An operation portion 14 is provided on an obliquely front side of the grip portion 13 at a position that can be operated with an index finger when the grip portion 13 is gripped. The operation portion 14 can be manually operated to perform a binding operation. The operation portion 13 is a swing member having a trigger shape in the present embodiment. The driver 25 (described below) is activated when the operation portion 14 is pulled.
The output portion 15 is provided in the vicinity of a tip end of the binding machine 10. At a tip end of the output portion 15, a protrusion forming portion 17 protrudes in a substantially L-shape, and an insertion opening 16 into which the bound member 50 is inserted is opened inside the protrusion forming portion 17. The driver 25 is housed in the output portion 15. A magazine portion 35 is provided on a side portion of the output portion 15.
The protrusion forming portion 17 is formed as a part of the housing 11 or is integrally fixed to the housing 11. A clincher 18 is provided on an inner surface of the protrusion forming portion 17 at a position where a tip end of the driver 25 (described below) is received. As shown in
The clincher 18 is configured to clinch leg portions 41a of the binder 41 struck out by the driver 25 to complete the binding. Specifically, the clincher 18 is a plate against which the binder 41 struck out by the driver 25 is pressed. A groove for guiding the leg portions 41a of the binder 41 is formed on a surface of the clincher 18, and the leg portions 41a of the binder 41 pressed against the clincher 18 are bent inward (clinched) along the groove.
The driver 25 is an elongated plate that performs a rectilinear motion by a drive mechanism (not shown) in order to strike out the binder 41 toward the insertion opening 16. As shown in
The magazine portion 35 is configured to load a plurality of binders 41. The binding machine 10 according to the present embodiment uses a binder packet 40 as shown in
The binder packet 40 is configured by coupling a plurality of binders 41 to each other. As shown in
The opening 41c which holds the bound member 50 is formed between the pair of leg portions 41a. When the binder 41 is struck out by the driver 25 and clinched, the leg portions 4 la are plastically deformed as shown in
As shown in
The magazine portion 35 is provided with a pusher 36 slidable along a longitudinal direction of the magazine portion 35. The pusher 36 is configured to bias the binder packet 40 loaded in the magazine portion 35 forward, and is always biased forward (in a direction of sending the binder 41 to a standby portion 37 (described below)) by a spring (not shown).
The magazine portion 35 is connected to the side portion of the output portion 15, and is configured to guide the binder packet 40 inside the output portion 15. Inside the output portion 15 continuous with the magazine portion 35, the standby portion 37 is provided which makes the binder 41 stand by in a state for being struck out. The standby portion 37 is provided between the driver 25 and the insertion opening 16, and the binder 41 standing by at the standby portion 37 is struck out by the driver 25 in a direction of the insertion opening 16.
When the binder packet 40 is loaded in the magazine portion 35, as shown in
When binding is performed using the binding machine 10 according to the present embodiment, the bound member 50 is first inserted into the insertion opening 16. When the operation portion 14 is operated in this state, the motor rotates and the diver 25 strikes out the binder 41 supplied to the standby portion 37 (see
As shown in
The base member 42 is a main body of the binder 41, and holds and binds the bound member 50 by plastic deformation. As described above, the base member 42 includes the pair of leg portions 41a, the connection portion 41b connecting the pair of leg portions 41a, and the coupling portions 44 which couples adjacent connection portions 41b.
The surface member 43 is a thin portion provided on a part of the surface of the base member 42. For example, the surface member 43 is formed integrally with the base member 42 by two-layer molding. The surface member 43 is not necessarily formed integrally with the base member 42. The surface member 43 may be adhered to the base member 42, or the surface member 43 may be provided by coating the base member 42, or the surface member 43 may be assembled to the base member 42.
In the present embodiment, the base member 42 is formed of plastic, and the surface member 43 is formed of rubber. Therefore, a friction coefficient between the surface member 43 and the bound member 50 is larger than a friction coefficient between the base member 42 and the bound member 50. That is, the surface member 43 provides the effect of slip prevention. In addition, the surface member 43 has an elastic limit higher than that of the base member 42, so that the impact can be alleviated when the surface member 43 hits other members.
As shown in
According to such a configuration, a large frictional force is generated between the surface member 43 and the bound member 50, so that the displacement of the bound member 50 is reduced. Therefore, stable binding can be obtained.
As shown in
As shown in
In the present embodiment, the surface member 43 is provided in a substantially U-shape on an inner side of the base member 42. However, the present invention is not limited thereto.
For example, as shown in
Further, when the binder packet 40 is pushed by the pusher 36, if the rib 35a and the surface member 43 are in contact with each other in a wide range, the frictional resistance may be increased, which causes a sending failure. In this respect, if the surface member 43 is not provided on the inner side of the connection portion 41b serving as a contact portion with the rib 3.5a, an increase in the frictional resistance can be prevented, and the binder packet 40 can be reliably sent.
As shown in
As shown in
A shape of a surface of the surface member 43 may have various forms, and may be determined according to the using environment and purpose. For example, as shown in
As shown in
As shown in
As described above, the binder 41 according to the present embodiment includes an elastically deformable surface member 43 on the surface of the substantially U-shaped base member 42 that is plastically deformable. According to such a configuration, as providing the surface member 43 on the inner surface and/or the outer surface of the base member 42, the effects such as stable binding and/or prevention of breakage can be obtained.
That is, if the surface member 43 is provided on the inner surface of the base member 42, the frictional resistance at a position in contact with the bound member 50 can be improved and the holding force of the binder 41 can be increased. Therefore, binding can be stably performed without displacement of the binder 41 even if the binding strength is appropriate not as strong as causing damage to the bound member 50. Further, the effect of preventing damage when the binder 41 hits other members can also be expected.
If the surface member 43 is provided on the outer surface of the base member 42, the buffering property at a position hitting other members can be improved. Therefore, even when the binder 41 is used at a location where vibration occurs, damage to other members can be reduced and breakage of the binder 41 can be prevented. Since the impact at hitting to other members is alleviated, the effect of preventing the binder 41 from falling off by the impact can be expected.
In the above-described embodiment, the surface member 43 is provided on both the pair of leg portions 41a. However, the present invention is not limited thereto, and the surface member 43 may be provided only on one of the leg portions 41a.
