Description

  The present invention provides, for example, a nail so that nails and screws can be driven at equal intervals in a predetermined pitch at the time of construction work such as flooring, wall construction, etc. The present invention relates to a positioning ruler capable of positioning a fastener driving tool such as a hammer or a screwing machine.

  When building and installing flooring and wall surfaces in residential buildings with fasteners such as nails and screws, there is a construction standard established to drive in nails and screws at predetermined intervals such as 150 mm and 200 mm pitches. Yes, when constructing nails and screws at predetermined intervals based on these standards, it has been conventional to draw down a reference line using a swing-down or inking device at the construction site and use a convex etc. Nail hammering and screw tightening was performed by attaching a nail and a screw tightening machine to the mark position with an equally spaced mark. Thus, since the operation | work which attaches the mark according to a reference | standard dimension is performed every time of construction of nailing or screw fastening, there existed a problem that this work was troublesome and troublesome, and the workability | operativity of fastener construction was impaired.

On the other hand, when constructing roofing material such as asphalt single, it is necessary to place the roofing material to be placed in a predetermined position and nail it so that it overlaps on the already nailing roofing material Therefore, a nailing machine in which such a roofing material is nailed is proposed in which an adjustment gauge for aligning the position of the roofing material is formed. This kind of adjustment gauge for roofing construction is formed on the lower surface of the magazine which is arranged so as to be almost parallel to the grip part for gripping the nailing machine, and has already been installed by this adjustment gauge. The dimension from the edge of the roofing material to the edge of the roofing material arranged on the roofing material can be made uniform. In addition, the position of the reference contact member can be adjusted and moved with respect to the longitudinal direction of the gauge body, and the dimensions can be changed by moving the reference contact member according to the dimensions of the roofing material to be constructed. It is configured.

  Position the nail driver so that the reference contact member of the adjustment gauge formed on the nailing machine for roof material construction of the above-mentioned prior art matches the already constructed nail driving site, and equidistantly at predetermined intervals. However, in the above-described prior art, the reference abutting member is formed on the lower surface of the magazine, so that the reference abutting member is made to coincide with the already nailing position. There is a problem that it is difficult. Further, in such a nailing operation with a nailing machine, the nailing machine is constructed by moving the nailing machine from the top to the bottom with respect to the vertically formed wall surface, or the nailing machine with respect to the vertical wall surface. As described above, the adjustment gauge installed on the lower side of the magazine must be gripped in the direction of moving the nailer. However, there was also a problem that the construction while moving from top to bottom and laterally became extremely difficult.

  The present invention solves the above-described conventional problems, and moves a fastener driving tool such as a nailing machine from the top to the bottom or in a horizontal direction in an arbitrary direction, while maintaining a predetermined distance from the position where it has already been constructed. It is an object of the present invention to provide a positioning ruler for a fastener driving tool that can be nailed or screwed at intervals.

  In order to solve the above-mentioned problems, a positioning ruler for a fastener driving tool according to the present invention has a housing that houses a driving mechanism for performing a nail driving operation and a screw tightening operation, and a fastener such as a nail or a screw is directed toward a construction material. In a fastener driving tool provided with a nose part forming an injection port for launch guidance and a grip part formed rearward from the housing, the base part of the telescopic rod whose length can be varied is provided as the fastener. The telescopic rod can be rotatably held at the nose portion of the drive tool, and the telescopic rod can be pulled out to an arbitrary length substantially parallel to the work surface and toward the front or left and right of the fastener drive tool. The rod is reduced so that it can be stored along the nose portion of the fastener driving tool.

  As described above, according to the present invention, the base portion of the telescopic rod whose length can be changed is rotatably held by the nose portion of the fastener driving tool, and the telescopic rod is moved in the front or left-right direction of the fastener driving tool. For example, the extension length of the telescopic rod is set to a predetermined construction interval such as 150 mm or 200 mm pitch, and the fastener driving tool is set to an arbitrary direction such as up and down or left and right. It is possible to drive a nail or a screw at a predetermined pitch by driving the fastener driving tool by aligning the tip of the telescopic rod with the already applied fastener while moving in the direction. Furthermore, since the telescopic rod is reduced so that it can be stored in the direction along the nose of the fastener driving tool, the telescopic rod is reduced when the fasteners are not installed at regular intervals as described above. The lot is not obstructed in the construction of the fastener by being accommodated along the nose portion of the fastener driving tool.

  To move the fastener drive tool in any direction, such as up and down or left and right, and to make it possible to change the total length in the nose part of the fastener drive tool for the purpose of constructing at an equal interval from the position where it has already been constructed The base of the extended telescopic rod is rotatably held so that the telescopic rod can be pulled out to an arbitrary length in an arbitrary direction such as the front or left and right directions of the fastener driving tool, and the telescopic rod is reduced. Thus, the present invention is realized by arranging the fastener driving tool so as to be rotated and stored in a direction along the nose portion, and more specific examples will be described below.
