Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of fasteners with a shaft, such as screws and nails, which are removably supported side by side, and the fasteners are driven one by one into a tool. The present invention relates to a holding band for a fixing device with a shaft portion such as a screw for feeding into a chamber.

2. Description of the Related Art A holding band for a fastener with a shaft such as a screw for supporting a number of fasteners with a shaft such as screws and nails side by side and feeding the fasteners one by one to a fastener driving chamber for a tool. Is already well known in Japanese Patent Publication No. 46-4040. This fastener holding band
A continuous body of fasteners for loading a large number of screws in a magazine into an automatic screw driving tool or the like. For this reason, the fastener holding band has an elongated base having holes formed at predetermined intervals to engage with the claws of the tool feeding mechanism, and the shaft of the fastener is removed by standing upright from both side edges of the base. A pair of tabs, which are supported and are formed at regular intervals, are integrally formed, and the shaft of the fastener is passed over and held by the pair of tabs. This holding band does not require welding or bonding in order to make a continuous body of fasteners, unlike a continuous body that directly connects continuous members such as nails and screws with wires or elongated plastic strings. preferable.

Problems to be Solved by the Invention A conventional holding band can satisfactorily strike an object such as a plate without any problem as long as the length of a shaft portion of a fixing tool to be held is normal or longer. Be included. However, when the shaft portion of the fastener is short, the tabs on the front side in the driving direction of the fasteners can easily fall down by the force of pushing the fasteners of the blade forward, but the tabs on the rear side are difficult to fall down. This causes the problem that the base holding the fasteners such as nails and screws is tilted and the shaft of the held fasteners tilts obliquely in the passage including the tool nose driving chamber. there were. When the posture is inclined like this,
When the blade pushes the fastener in the driving chamber or the passage, it is not preferable because it hinders the smooth feeding of the fastener and induces a jam of the fastener such as a nail jam in the passage.

In order to prevent the posture from being inclined, a protrusion may be formed on the tool to limit the posture of the fixing shaft, but this protrusion prevents the rear tab from falling down and moves the fixing from the holding band. There is a problem that it cannot be removed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a holding band for a fixing tool that can be driven without obliquely setting the posture of the fixing tool shaft when the blade is driven, even if the fixing tool has a short shaft.

Means for Solving the Problems In order to achieve this object, according to the present invention, a number of fasteners with a shaft such as screws and nails are juxtaposed and detachably supported, and the fasteners are driven one by one. In order to feed the tool into the fastener driving chamber, an elongated base having holes formed at predetermined intervals for engaging with claws of a tool feeding mechanism, and a fastener shaft standing upright from both side edges of the base. A retaining band for a fastener integrally formed with a pair of tabs formed at regular intervals for removably supporting a portion, and a laterally protruding base lock on at least one side edge of the base. A holding band for a fastener is provided, wherein a projecting piece is formed.

In addition, according to the present invention, in addition to the above-described features, a notch that helps the tab to fall forward at the time of driving of the fastener is formed in at least the rear tab as viewed in the driving direction. The notch is provided with a retaining band formed away from the base at a position where the rear tab falls down with a smaller radius than the tab on the front side in the driving direction.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a fastener holding band 1 of the present invention, in which a shaft 3 of a screw 2 as a fastener with a shaft is detachably held, and the held screw 2 is driven into a nose 5 of a tool. The manner in which the object is driven from the chamber 6 by the blade 7 is shown. Hereinafter, in this embodiment, a screw is used as a fixing tool for convenience of explanation. However, the fixing tool is not limited to a screw, and may be, for example, a fixing tool with a shaft such as a nail.

Details of the fastener holding band 1 of the present invention are shown in FIGS.
As shown in (c), a large number of screws 2 as fixing members with a shaft are juxtaposed and held detachably, and the screws 2 are fed one by one to a fixing tool driving chamber 6 of a driving tool. It is formed with functions. For this reason, holding belt 1 is
Similarly to the fastener holding band described in Japanese Patent No. 40, an elongated base 11 having holes formed at predetermined intervals to engage with the claws 8 (FIG. 1) of the tool feeding mechanism, and both side edges of the base 11 The base 11 and each of the tabs 12 are integrally formed of a material such as plastic and the like.

Further, description of the details of the fastener holding band 1 will be continued.
The base 11 has one screw 2 engaged with the feeding claw 8 of the feeding mechanism of the screw driving tool as a fixing tool and held by each tab 12 one by one in the driving chamber 6 of the nose 5. To send to
A hole 13 is formed. Each tab 12 is formed by a pair of arms 14, 14 that sandwich the side surface of the shaft 3 of each screw 2 from both sides. As shown in the figure, a middle portion of the arm 14 is cut so as to hold the shaft 3 of the screw 2, and the distal end side is formed with a mating partner so that the shaft 3 of the held screw does not come off. The arm is formed so as to approach the arm tip side. Therefore, the pair of arms 14 and 14 form a bay-shaped hole having a narrow entrance for holding the screw shaft 3. The distance between the tabs 12 and the hole 13 in the base 11
Is such that the screw 2 is sent to the driving chamber 6 one by one by the claw 8. Further, as shown in the drawing, each tab 12 is preferably independent of an adjacent tab 12 by a slit 15, so that a large number of screws 2 are held side by side, and It can be wound as shown in the publication and loaded into the magazine of the screw driving tool.

In the present invention, in addition to the structure of the ordinary fastener holding band 1, as shown in FIGS. 1 and 2 (c),
On the side edge of the base 11, a protruding piece 16 for protruding the base is provided.
Are formed. As shown in FIG. 1, the base locking projection 16 has a function of locking with the guide 17 of the tool to keep the base 11 in a constant posture. This projecting piece 17 is
As shown in FIG. 2 and FIG. 2 (c), the base 11 may be extended laterally from both side edges of the base 11. However, as long as the base 11 has a function of maintaining a constant posture, it is formed only on one side. You may. In this case, the projecting piece 17 is formed on the side (the upper side in the example shown in FIG. 5) that functions effectively so that the base 11 does not fall even when the screw 2 is driven by the blade 7. preferable.

Further, in the present invention, the tabs at the rear (upper side in the example shown in FIG. 1) viewed at least in the driving direction among the tabs.
When the screw 2 as a fastener is driven into the tab 12, the tab 12
A notch 18 is formed to help the child fall forward. This notch 18, as shown by the imaginary line in FIG.
The rear tab is formed at a position away from the base 11 so that the rear tab overlaps and falls down on the tab 12 on the front side (lower side in the example shown in FIG. 1) in the driving direction. .

Generally, when driving the screw 2 with the blade 7, the tab 12 on the rear side (upper side in FIG. 1) hardly falls down, but rather the tab 12 on the front side (lower side in FIG. 1) falls down first. Tend. When the tab 12 on the front side falls down in this manner, the posture of the screw 2 is inclined obliquely as shown by the line 1 in FIG. As described above, if the posture of the screw 2 is oblique, the screw 2 cannot be smoothly fed into the passage of the screw 2, resulting in jamming or jamming in the passage. It is the above-mentioned notch 18 that prevents the inclination of the posture of the screw 2 as the fixing member with the shaft portion, and the notch 18 allows the rear side (upper side in FIG. 1) to be prevented.
The tab 2 of the front side (lower side of FIG. 1) falls down easily together with the tab 12, and the screw 2 moves from the holding band 1 without tilting while the shaft portion 3 remains perpendicular to the object. Removed.

In addition, it is preferable that notches 19 are formed in the tabs 12 of the holding band 1 to help the tabs 12 fall forward when the screw 2 is driven in the front tabs 12 as viewed in the driving direction. . This notch 19, as shown by the imaginary line in FIG.
The rear tab 12 is formed at a position closer to the base 11 than the cut 18 of the rear tab 12 so that the rear tab 12 overlaps and falls down in parallel. When formed in a position closer to the base 11 than the position of the notch 18, the tab 12 on the front side comes into close contact with the surface 20 of the nose driving chamber 6 as shown by the imaginary line in FIG. not only has the advantage that does not interfere with the second implantation, becomes the radius R ₁ of the falling of the front side of the tab 12 is larger than the radius R ₂ of the tilting of the rear side of the tub 12, the blade 7 screws 2 When driving, there is also an advantage that the screw 2 is not inclined obliquely.

A state in which the fixing tool with a shaft portion such as a screw or a nail is held by using the holding band 1 of the present invention is shown by a solid line in FIG. FIG. 4 shows an example in which the shaft portion 3 holds a fixing tool formed short. Even if the shaft portion 3 is a fixing tool formed short, the holding band 1 of the present invention is held without any problem, and the driving posture is not inclined.

According to the present invention, since at least one side edge of the base of the holding band is formed with a base locking projecting piece that protrudes laterally, the fixing tool having the blade in the nose driving chamber is provided. The base is held by the guide of the nose so that it does not incline even if it is driven toward the object, so that the fixing device does not tilt its position in the nose driving chamber or passage, and the clogging of the fixing device That is, jam can be prevented.

In addition, according to the present invention, in addition to the above-described features, a notch that helps the tab to fall forward at the time of driving of the fastener is formed in at least the rear tab as viewed in the driving direction. The notch is formed and the notch is provided with a retaining band formed at a position where the rear side tab falls down with a smaller radius than the tab on the front side in the driving direction and away from the base. It is ensured that the tab falls down without tilting the fastener, and thus more reliably prevents jamming of the fastener in the nose driving chamber or passage of the fastener.
