Abstract

PURPOSE:To omit an application process of a caring resin and the like by forming oblique faces, wherein faces for contacting with fixing tool stems are in face contact entirely in the tab thickness direction of a fixing tool holding belt, in notches of the tabs. CONSTITUTION:In tabs 4 formed to make a pair by bending both sides of a base body 3 having feeding holes 7, curved-shape notches 6 each detachably holding a stem part of a nail 2 are formed. A face of this curved shape notch 6 for contact with the stem part 5 is obliquely formed so that it may be in face contact entirely in the thickness direction of the tab 4. Accordingly, a contact area is wide so that application of a curing resin and the like can be omitted and holding force can be enlarged.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention comprises an elongated base and tabs rising from both edges of the base, and the tabs removably support the shafts of fasteners such as nails and screws. The present invention relates to a structure for connecting fasteners to a fastener holding band in which the fasteners are held diagonally in parallel with the fastener holding band in which a bay-shaped notch is formed.

2. Description of the Related Art A fixing device is provided with an elongated base and a tab extending upright from both edges of the base, and the tab has a bay-shaped notch in which the shaft of a fixing device such as a nail or screw is removably supported. The retaining band is well known from Japanese Patent Publication No. 46-4040. This fastener holding band connects the fastener shafts in parallel in a direction perpendicular to the longitudinal direction of the holding band, and the holding band supporting the fastener can be wound into a coil shape and stored in a magazine. This is used to feed a large number of fasteners from the magazine of a powered fastener driver to the nose.

In the fastener holding band well known from Japanese Patent Publication No. 46-4040, etc., 1, a large number of fasteners such as nails straddle the base of the holding band and are held in parallel to each other at right angles to the longitudinal direction of the base. has been done. In contrast to this fixing device connection structure in which the fixing devices are held in orthogonal parallel arrangement, there is also known a connection structure in which the fixing devices are held in parallel across the base of the holding band and diagonally with respect to the longitudinal direction of the base. In the case of this diagonal parallel arrangement, compared to the orthogonal parallel arrangement, the enlarged diameter parts such as nail heads can be arranged with a shift from each other, so the advantage is that the number of fixing devices to the retaining band can be increased. .

Problems to be Solved by the Invention In the above-mentioned structure for connecting fasteners to fastener holding bands arranged diagonally in parallel, compared to the fastener connecting structure in orthogonal parallel arrangement, the shaft of the fastener is attached to the notch of the tab. However, there was a problem in that the contact area was small and the holding force was small. To solve this problem, Japanese Utility Model Publication No. 2-4243 proposes a connection structure in which a curable resin is applied to the contact surface between the fastener shaft and the notch. However, the connection structure described in this publication has the disadvantage that it requires a cumbersome process of applying hardening resin to the notch in the retention band after connecting the nail to the retention band. It also had the disadvantage of raising the price.

Therefore, an object of the present invention is to provide a structure for connecting diagonally arranged fasteners to a retaining band, which does not require additional processes such as resin application, and which has a strong holding force. The object of the present invention is to provide a connection structure to a retaining band.

Means for Solving the Problems In order to achieve the above object, the present invention includes an elongated base body and a pair of tabs rising from both edges of the base body, each tab being fixed with a nail, screw, etc. A fixing device holding band in which a fixing device holder is formed with a notch in which the shaft portion of the device is removably supported, and the fixing device is held parallel to each pair of tabs, straddling the base and diagonally to the longitudinal direction of the device. In the connection structure of the fastener to the band, the notch of each tab is cut in the direction of the fastener shaft so that the surface in contact with the fastener shaft is in contact with the fastener shaft throughout the tab thickness direction. Provided is a structure for connecting a fastener to a fastener holding band, which is characterized by having a surface formed obliquely along the fastener holding band.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 shows a connecting structure according to the present invention. In this connecting structure, nails 2 as fixing devices to the retaining band 1 are held in parallel across the base 3 of the retaining band 1 and obliquely with respect to the longitudinal direction. ing. FIG. 2 shows a developed view of the retaining band 1, and FIGS. 3 and 4 show sectional views taken along the line ■--■ and IV-ff in FIG. 2, respectively.

Before explaining the structure for connecting a nail or the like to a retaining band according to the present invention, a general description will be given of the fastener retaining band 1 that holds a fastener such as a nail 2 with reference to FIG. 2. The holding band 1 for a fastener such as a nail 2 is made of an integrally molded piece of flexible plastic material, as is well known from Japanese Patent Publication No. 46-4040. The retaining band 1 includes a base body 3 and tabs 4.4 rising from both edges of the base body 30 in pairs. Although FIG. 2 is a developed view and does not stand up, each tab 4 stands up with respect to the base 3 as shown in FIG. 1 in order to support the fixing tool. This tab 4.4 is formed with a drop-shaped notch 6 in which a shaft 5 of a fastener 2 such as a nail or screw is removably supported. In addition, holes 7 are formed in the base body 3 at regular intervals in the longitudinal direction of the base body 3, into which feed claws of a holding band feeding mechanism (not shown) of a fastener driving machine such as a nailer are engaged. There is. Since this holding band l is made of a flexible plastic material, it can be wound into a coil while holding a large number of fasteners such as nails 2 on the tab 4, and the wound body can be used with a nail gun or the like. By storing the nails in a magazine and guiding them to a holding band feeding mechanism such as a nail gun, the nails can be automatically fed to the nose and continuously driven into objects such as boards.

In the present invention, unlike the fastener connection structure well known from Japanese Patent Publication No. 46-4040, as shown in FIG. They are arranged diagonally in parallel in the longitudinal direction. Compared to the orthogonal parallel arrangement disclosed in Japanese Patent Publication No. 46-4040, this diagonal parallel arrangement connection structure allows the enlarged diameter parts of the nail heads etc. to be shifted from each other. This has the advantage of increasing the number of Because of the diagonal arrangement, the tabs 4.4 that form the upper and lower pairs in FIGS.

Note that this diagonal orientation is preferably such that the tip of the nail precedes the head □, so that it can be driven easily with the handle of the nail gun held up. In the conventional diagonally arranged connection structure, compared to the orthogonal parallel arrangement connection structure, the contact area of the fastener shaft with the notch of the tab was small, and the problem was that the holding force was small. .

The present invention does not require the coating process of a curable resin as described in Utility Model Publication No. 2-4243, and has a high holding power.
To provide a connection structure in which fasteners such as nails 2 are arranged diagonally in parallel to a retaining band 1. Therefore, in the present invention, FIGS.
As is clear from the figure, the cut 6 of each tab 4 is formed in such a way that the surface 9 of the nail 2 serving as the fixing tool is in contact with the nail shank over the entire tab thickness direction. It has a surface formed obliquely along the axis direction. In addition, surface 9 is
It is sufficient if the tab can be in contact with the shaft portion 5 of the nail 2 over the entire thickness direction of the tab, and although it is formed obliquely in FIG. 3, it is not formed obliquely in FIG. 4.

Effects of the Invention According to the diagonally parallel arrangement connection structure of fasteners to the retaining band according to the present invention, each tab has a notch in which the surface in contact with the fastener shaft is in contact with the fastener shaft over the entire thickness direction of the tab. Since it has a surface formed diagonally along the axis of the fixing device so that it faces the fixing device, the area of contact with the shaft of the fixing device, that is, the contact area is different from the point contact state in the case of the conventional diagonal connection structure. Moreover, since the contact area is increased by the slanted surface of the notch compared to the orthogonal parallel arrangement, the holding force of the tab on the fastener shaft becomes considerably stronger. Therefore, a connection structure with a sufficiently strong fixing tool holding force can be obtained without additional steps such as applying a curable resin or the like.
