[0001]

[Industrial applications]

 The present invention relates to a driving machine having a driving guide for guiding on a mounting material when driving a fastener.

[0002]

[Prior art]

 Fig. 2 shows a state in which a conventional driving tool with a driving guide is used to drive floor materials during flooring work. The mounting material 4, which is a floor material, has a convex portion 5 at approximately the center of the end face, and the corner 6 of the convex portion 5 is formed with an arbitrary angle and the fastener 1 is driven to attach the mounting material 4 to, for example, a floor. The flooring is performed by fixing it to the attached material 7 and fitting the convex portion 5 of the attaching material 4 to the concave portion of the next attaching material 4. In the driving guide 3 of the conventional driving machine, as shown in FIG. 2, the driving guide 3 is attached in front of the injection portion 2 in order to drive the stopper 1 at an accurate point, and the convex portion 5 of the mounting member 4 is attached. Is a structure that guides the upper corners of the. Moreover, since the convex portion 5 is generally made of wood, it was easily cracked.

[0003]

[Problems to be solved by the device]

 As shown in FIG. 2, in the structure of the conventional driving guide 3, when the stopper 1 is driven, the reaction force to the upper side of the driving machine generated when the driving rod 12 moves in the driving direction of the stopper 1. When the driving tool body 8 receives and the driving tool flies upward, the driving point is displaced, and as shown in FIG. 3, the mounting member 4 forms a convex portion 5 at approximately the center of the end face. Therefore, when the fastener 1 is driven, the projection 5 is easily bent by the impact of the driving rod 12, and the projection 5 is cracked. If this crack occurs, there is a problem in that the workability is extremely poor because the subsequent mounting of the mounting member 4 into the recess is not successful. An object of the present invention is to solve the above problems and improve the finish and workability of flooring construction with this type of driving machine.

[0004]

Means for Solving the Problems The above object is achieved by providing a driving guide having an insertion member which is inserted between at least a lower surface of a convex portion and an upper surface of a material to be attached, near an injection portion of a driving machine. .

[0005]

[Action]

 In the driving machine having the driving guide configured as described above, the bending of the convex portion that occurs when the fastener is driven is inserted into the lower portion of the convex portion and is blocked by the insertion member, so that the convex portion is not deformed or cracked. It can be prevented. Also, the reaction force generated when the stopper is driven can be reduced, and the stopper can be driven at an accurate point. When the guide part in front of the ejection port of the driving machine is set at the driving point (the corner of the convex part), the guide member in front of the ejection port and the upper surface of the convex part are in contact with each other due to the contact between the insertion member and the lower surface of the convex part. Since the corners of the will not shift, it will be easier to set.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a state in which a driving machine equipped with a driving guide is performing a driving operation. The mounting member 4 has a convex portion 5 substantially at the center of the end surface, and the next mounting member 4 is applied by flooring. It has a structure that fits into the recess of the. On the other hand, the driving machine has a driving guide 3 attached to an injection section 2 for driving a stopper 1. The driving guide 3 guides the vicinity of the corner 6 on the upper surface of the convex portion 5, and when the driving machine body 8 is set on the mounting member 4, the lower surface of the convex portion 5 and the mounted member 7 are set. A guide having an insertion member 11 formed at a constant angle (approximately 45 ° in the case of flooring work) with respect to the launching direction of the fastener 1 of the driving machine so that it can be inserted into the space formed by the upper surface. The structure is provided with the portion 10. The insertion member 11 is attached near the lower portion of the injection portion 2 so as to prevent the convex portion 5 from being deformed when the stopper 1 is driven. As shown in FIG. 1, the operation of driving the fastener 1 with the driving machine configured as described above is performed by inserting the guide 10 into the lower portion of the convex portion 5 of the mounting member 4 and then by using the guide 9 mentioned above. 5 Guide the corners 6 on the upper surface and tilt the driving tool body 8 at a certain angle before setting. In this state, the driving operation is performed and the stopper 1 is driven, but since the insertion member 11 of the guide portion 10 is inserted in the lower portion of the convex portion 5, the stopper 1 or the driving rod 12 is convex at the time of driving. Even if the portion 5 is bent downward, the insertion member 11 can prevent the bending. Further, when the fastener 1 is driven and the driving machine body 8 receives the reaction force when the fastener 1 is driven, the insertion member 11 of the guide portion 10 comes into contact with the lower surface of the convex portion 5 of the mounting member 4 to prevent the lifting of the body. , That recoil can be reduced.

FIG. 4 shows a second embodiment of the present invention, in which the driving guide 3 is attached to the tip of a push lever 13 of a driving machine having a safety device. The safety device has a structure in which when the stopper 1 is driven, the stopper 1 is pushed out only by pushing the push lever 13 upward and further pulling the trigger 4. Also in this structure, similarly to the driving guide 3, the insertion member 11 of the guide portion 10 attached to the push lever 13 is inserted into the lower portion of the convex portion 5 of the mounting member 4, and further into the corner 6 of the upper surface of the convex portion 5. The driving tool body 8 is tilted at an angle of about 45 ° against the mounting member 4 and pressed against the mounting member 4 by applying the guide portion 9, and the push lever 13 is pushed up to operate the trigger 14 to perform the driving operation.

FIG. 5 shows a third embodiment of the present invention, in which the guide portions 9 and 10 are integrated in the above embodiment, but the guide portion 9 of the driving guide 3 is replaced with the injection portion. 2 The guide 10 is attached near the front and the guide 10 is attached to the push lever 13. Also in this structure, like the driving guide 3, the insertion member 11 of the guide portion 10 pressed against the push lever 13 is inserted into the lower portion of the convex portion 5 of the mounting member 4, and the driving machine main body 8 is mounted. Inclining in the direction of about 45 ° against the mounting member 4, pushing the push lever 13 upward, applying the guide portion 9 to the corner 6 of the convex portion 5 and operating the trigger 14 to perform the driving operation. Further, as shown in FIG. 6, the guide portions 9 and 10 may be separately configured, and the position of the insertion member 11 may be adjustable according to the shape of the convex portion 5 of the mounting member 4.

[0009]

[Effect of device]

 According to the present invention, the driving guide is provided with the insertion member that is inserted between the lower surface of the convex portion of the mounting material and the upper surface of the mounting material, so that the convex portion can be prevented from being deformed or cracked when the fastener is driven. Furthermore, the recoil of the driving machine main body at the time of driving can be reduced by the contact between the insertion member and the lower surface of the convex portion, so that the finish after mounting on the mounted material such as the floor material is clean and the convex portion Deformation and cracks can be prevented, making it easy to incorporate floor materials and the like. Furthermore, since it is easy to set at the driving point, the workability in flooring construction can be improved.
