Description

  The present invention supports the support tape of the fixing tool, more specifically, the screw nails and nails which are the fixing tools are arranged and supported at regular intervals, and the screw nails and nails can be driven continuously using an electric tool. It is related with the support tape for doing.

  Conventionally, a support tape 1 for supporting a screw nail at a constant interval in order to enable the screw nail to be driven continuously with an electric screwdriver tool is a belt-like shape using a synthetic resin as shown in FIGS. Support portions 3 for inserting the screw nails A into the base 2 are provided at regular intervals in the length direction, and the support portions 3 are provided in the belt-like base 2 with an inner diameter suitable for the shaft portion B of the screw nails A. It is formed by a hole 4 and a cylindrical support tube 5 projecting around the insertion hole 4 on the back side of the belt-like substrate 2, and feed notches 6 are formed on both side edges of the belt-like substrate 2. Is provided at the same pitch.

  Such a support tape 1 is mounted on an electric driver tool 7 as shown in FIG. 9 and used for continuous driving of the screw nail A.

  By the way, when the supporting tape 1 is mounted on the electric driver tool 7 and the screw nail A held by the supporting tape 1 is driven, the head C of the screw nail A is provided on the band-shaped substrate 2 with respect to the band-shaped substrate 2. The peripheral part of the support part 3 is elastically deformed so as to expand its diameter and passes.

  In such a support tape 1, in order to improve the passage of the head C of the screw nail A with respect to the periphery of the support portion 3 of the belt-like base 2, the support cylinder 5 is provided around each support portion 3 of the belt-like base 2. A plurality of kerfs 8 extending outward as starting ends are provided in a radial arrangement. The cut groove 8 reaches a midway position along the axial direction of the support cylinder 5 at a portion on the support cylinder 5 side.

  As described above, when the four cut grooves 8 are provided in a radial arrangement around each support portion 3 of the belt-like substrate 2, the portion between the adjacent cut grooves 8 becomes the elastic bendable piece 9, and the support portion 3. The periphery is surrounded by this elastic bendable piece 9, and the shaft portion B of the screw nail A is substantially held by each elastic bendable piece 9 and the support cylinder 5.

  By providing the kerf 8 as described above, each elastic bendable piece 9 squeezed by the head C is bent at the position of the line connecting the tip of the kerf 8 when the head C of the screw nail A passes. In addition, the lower portion of the support cylinder 5 is broken from the extended portion of the kerf 8 so that the head C of the screw nail A can be passed.

  Conventionally, as shown in FIG. 6, the kerf 8 provided on the belt-like substrate 2 of the support tape 1 has a linear shape with a narrow width, and four that extend outward from the support cylinder 5 as the starting end, and FIG. As shown in FIG. 1, a fan-shaped fan or a fan-shaped groove 8 that extends toward the tip side has been proposed (see, for example, Patent Document 1).

Japanese Patent No. 2903262 (FIGS. 2, 4, and 6)

  By the way, in the case of the former linear kerf 8 having a narrow width, the elastic bendable pieces 9 between the kerfs 8 adjacent to each other are adjacent to each other because the planar area is increased by the narrow width of the kerf 8. The distance between the ends of the kerf 8 is increased.

  Between the tips of the adjacent kerfs 8 becomes the bending base point of the elastic bendable piece 9 when the head C passes, but if the distance between the tips of the adjacent kerfs 8 is long, naturally the bending base point Therefore, the elastic bendable piece 9 is inferior in bending elasticity, and a large resistance is generated when the head C of the screw nail A passes through and spreads out the elastic bendable piece 9. The screw nail A is not easily pulled out from the belt-like substrate 2, and a large torque electric driver tool is required to pass the head C of the screw nail A through the belt-like substrate 2.

  On the other hand, in the case of the kerf 8 formed in the latter fan-shaped or triangular shape, the planar area of each elastic bendable piece 9 between the kerfs 8 adjacent to each other is increased by the width of the kerf 8. The distance between the tips of the adjacent kerfs 8 serving as the bending base point of the elastic bendable piece 9 is shortened, whereby the bend elasticity of the elastic bendable piece 9 is improved and the head C of the screw nail A passes. Thus, since the generation of resistance when the elastic bendable piece 9 is spread out is reduced, the screw nail A can be easily pulled out from the belt-like base 2 and there is an advantage that the torque of the electric driver tool can be reduced.

  However, when the bending elasticity of the elastic bendable piece 9 is improved, the holding force of the screw nail A by each elastic bendable piece 9 is weakened accordingly, so that when the screw nail A is to be driven horizontally, The nail A has an inclined posture in which the tip is lowered, and there is a problem that a situation in which the screw nail A cannot be driven horizontally occurs.

  Further, when the screw nail A is inclined, the screwdriver nail A and the screw nail A are not aligned with each other. When screwing is performed in such a state, the wall material into which the screw nail A is screwed is damaged, In an extreme case, the work is interrupted and the screw nail A that has digged in must be removed.

  Accordingly, an object of the present invention is to form the structure of the support portion provided on the belt-like base so that the flexural elasticity is improved while maintaining the retaining force of the screw nail, to ensure the detachability of the head of the nail, and It is an object of the present invention to provide a support tape for a fixing tool capable of preventing the occurrence of inclination of a screw nail during horizontal driving.

  In order to solve the above-described problems, the present invention provides a guide groove in which support portions for inserting the fixing tool are provided at regular intervals in the longitudinal direction of the belt-like substrate, and the belt-like substrate is provided on the sliding member of the electric tool. In the support tape of the fastener that is inserted intermittently at a pitch that matches the interval between the support portions by the feed claws provided on the sliding member, the support portions are externally mounted around the support portions of the belt-like substrate. A configuration is adopted in which a plurality of kerfs extending in the radial direction are provided in a radial arrangement, and further, through holes are provided at positions on both sides sandwiching the tip at the tip of each kerf.

  Each of the kerfs is formed in a straight line having a narrow width, and the tip thereof is set to a length located outside the outer diameter of the head of the fixing tool held by the support portion. You may make it provide in the position which overlaps with the virtual circle which connects the front-end | tip of a cut groove, or the inner side or the outer side position which adjoined this virtual circle.

  Here, the support tape is made of synthetic resin, and the support portion provided on the belt-like base is provided with an insertion hole provided with an inner diameter suitable for the shaft portion of the screw nail and projecting around the insertion hole on the lower surface side of the belt-like base. The groove is formed in the cylindrical portion of the support tube, and reaches the middle position along the axial direction of the support tube at the portion on the support tube side, and is fed to both side edges of the belt-like substrate. Notches are provided at the same interval as the support portion.

  As described above, according to the present invention, a plurality of kerfs extending outward from the support portion as a starting end are provided in a radial arrangement around each support portion of the belt-like substrate forming the support tape. Since the through-holes are provided at the positions on both sides of the front-end portion, the bending elasticity of the elastic bendable piece formed between the kerfs is improved and provided by providing the through-holes on both sides. The detachability of the fixing tool with respect to the part is improved, and the elasticity at the bending base point of each elastic bendable piece can be appropriately secured, thereby preventing the fixing tool from being inclined when the fixing tool is in a horizontal state. Then, the fixing tool can be driven horizontally without any trouble.

  A plurality of kerfs extending outward from the support portion as a starting end are provided in a radial arrangement around each support portion of the belt-like base member provided with support portions through which the fixing tool is inserted at regular intervals along the longitudinal direction. In addition, through holes are provided at positions on both sides of the front end of each kerf so as to sandwich the front end, and the bending elasticity of the elastic bendable piece formed between adjacent kerfs is improved by the through hole.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 to 5, the support tape 11 is made of synthetic resin, and support portions 13 through which the fixing tool is inserted are provided at regular intervals in the longitudinal direction of the belt-like substrate 12. The cutouts 14 for feeding are provided at the same pitch as the support portion 13. Examples of the fixing tool include a screw nail and a nail, and an example using the screw nail A will be described below.

  The support portion 13 is formed by an insertion hole 15 provided with an inner diameter suitable for the shaft portion B of the screw nail A, and a cylindrical support tube 16 projecting around the insertion hole 15 on the lower surface side of the belt-like base 12. A plurality of kerfs 17 extending radially outward from the support portion 13 are provided around the support portions 13 of the belt-like substrate 12 in a radial arrangement. Through-holes 18 penetrating the belt-like substrate 12 are provided at positions on both sides of the substrate.

  Each of the above-described kerfs 17 is formed in a narrow linear shape, and as shown in FIG. 1, four outwardly extending from the support cylinder 16 as a starting end are provided in a radial arrangement, and the tip thereof is the support portion 13. Is set to a length located outside the outer diameter of the head C of the screw nail A held by the screw nail A, and each kerf 17 is partway along the axial direction of the support tube 16 at a portion on the support tube 16 side. The position has been reached.

  The through-hole 18 is formed in an arbitrary shape such as a small-diameter circular hole, long hole, or elliptical hole. In the illustrated case, the through-hole 18 is located at a position close to the tip of each cut groove 17. However, it may be provided at a position that overlaps the virtual circle or a portion that approaches the outside of the virtual circle.

  By providing the cut groove 17, the space between the adjacent cut grooves 17 becomes an elastic bendable piece 19, and the insertion hole 15 is formed by being surrounded by the divided elastic bendable piece 19. The portion forming the insertion hole 15 and the support tube 16 elastically hold the shaft portion B of the screw nail A.

  When the head C of the screw nail A passes through the support portion 13, the elastic bendable piece 19 has a bent base point between the tips of adjacent kerfs 17, but the kerfs 17 have a narrow linear shape. As a result, the distance between the tips of the adjacent kerfs 17 becomes longer.

  However, the through-holes 18 provided on both sides at the tip of each kerf 17 are positioned on a line connecting the tips of the adjacent kerfs 17, and the amount of the synthetic resin of the belt-like substrate 12 at the bending base point is reduced. It can be reduced by the amount of the both side through-holes 18, whereby the bending elasticity of the elastic bendable piece 19 can be improved.

  In this way, the cut groove 17 is formed in a narrow linear shape, and the amount of the synthetic resin of the belt-like base 12 at the bending base point is reduced by the amount of the both side through holes 18, whereby the screw nail A by the elastic bendable piece 19. Thus, the bending elasticity of the elastic bendable piece 19 can be moderately improved while maintaining the holding force, whereby the support portion 13 of the support tape 11 improves the detachability of the head C of the screw nail A. However, it is possible to prevent the threaded nail A from being inclined during horizontal driving.

  In the case shown in the figure, the support tape 11 is provided with protrusions 20 at the peripheral positions of the support portions 13 on one surface side of the belt-like base 12, and when loaded into the electric driver tool, the guide groove of the electric driver tool and the support tape 11 are provided. The protrusions 20 projecting into the gaps between them prevent the support tape 11 from rattling in the vertical direction in the guide groove.

  The support tape 11 of the present invention is configured as described above, and in the state where the threaded nail A is held by each support portion 13, as shown in FIG. A screw nail A inserted into the guide groove, engaged with the feed notches 14 on both side edges of the support tape 11 in the guide groove, and held by the support portion 13 located in the guide groove, It is arranged coaxially with the driver.

  In the above state, when the contact fitting provided at the tip of the sliding member is applied to the placement surface and the tool body is pushed toward the placement surface, the tool body and the guide are guided against the sliding member that stops. Since the case and the rotating driver move forward, the driver engages with the driver engaging groove of the head C of the screw nail A in the middle of movement, and pushes it toward the placement surface while rotating the screw nail A. The head C of the screw nail A is forcibly passed through the support portion 13 of the support tape 11 and screwed into the placement surface.

  When the head C of the screw nail A forcibly passes through the support portion 13 of the support tape 11, each elastic bendable piece 19 expands while curving in an arc from the bent base point as shown in FIGS. The lower portion of the support cylinder 16 is broken from the extended portion of the cut groove 17 to allow the head C of the screw nail A to pass through. Since the through-hole 18 improves the bending elasticity of the elastic bendable piece 19, the screw nail A can be easily pulled out.

  Further, since the kerf 17 is formed in a narrow linear shape, the elasticity at the bending base point of each elastic bendable piece 19 can be appropriately ensured, thereby making the screw nail A horizontal. In this case, the inclination of the screw nail A can be prevented, and the horizontal driving of the screw nail A can be performed without any trouble.
