BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail guiding device for a nailing machine.

[0002]

2. Description of the Related Art Conventionally, in a nail guiding device of a nailing machine of this kind, a tip member of a bush lever provided at a nail ejection portion of the nailing machine has a diameter substantially the same as that of the nail ejection port. A configuration has been devised in which the lower end of the injection portion is formed as a tapered surface to prevent the nail from being driven obliquely or the nail head from being bent and driven. (For example, Japanese Utility Model Laid-Open No. 2-51079)

SUMMARY OF THE INVENTION An object of the present invention is to provide a nail guiding device which has a structure different from that of the above-mentioned conventional one and which can simplify the structure and can reliably guide a nail to be driven until the end of nailing. It is in.

[0004]

In order to achieve the above object, the present invention provides a driver guide in which a nail is received and a driver for hitting the nail is reciprocally inserted, and the driver guide is provided. And a contact arm that is reciprocally mounted with respect to the contact arm and is connected to a control member that controls a hitting operation of the driver.A guide slit having a predetermined length is provided at a lower end portion of the driver guide. A plurality of guide ridges are formed in the axial direction, and project from the tip end member of the contact arm so as to be reciprocally fitted into the guide slit. The guide ridge is substantially formed with the inner peripheral surface of the driver guide. A guide path that is formed on the same surface and that is in contact with the driven surface is maintained such that the lower end of the driver guide always projects from the lower end surface of the driver guide. It is obtained by the subject matter that form.

[0005]

According to the above construction, the nail is reliably guided from the initial stage to the end of the driving by the guide ridge of the distal end member of the contact arm together with the driver guide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. In the drawing, reference numeral 1 denotes the entire nailing machine of the present embodiment. When the nailing machine 1 is roughly classified, a driver 2 for hitting a nail T is built in so as to be reciprocally movable, and the driver 2 is inserted therethrough. A main body 4 having a driver guide 3 for accommodating the nail T; a handle 5 integrally formed with the main body 4 and having a trigger 5a for controlling the impact of the driver 2; And a nail magazine 6 for accommodating a large number of nails T and supplying the nails T one by one into the driver guide 3. The nailing machine 1 is driven by the retracting operation of the trigger 5 a. The driver 2 is reciprocated continuously many times.
The nail T is driven by a large number of continuous hits.

The nail guide path 3a in the driver guide 3 has an inner periphery formed to have substantially the same diameter as the diameter of the head TH of the nail T, and has a substantially lower end portion having a predetermined length with the lower end surface opened. A plurality of guide slits 7 to 7 (three in the figure are shown) are formed at equal intervals in the axial direction.

A contact arm 8 is mounted on the driver guide 3 so as to be able to move up and down. The contact arm 8 is a substantially cylindrical tip member 9 fitted on the outer periphery of the tip of the driver guide 3. And an arm member 10 extending upward from the tip member 9, and guide projections 11-11 inserted into the guide slits 7-7 in the inner peripheral axis direction of the tip member 9. The guide projections 11 to 11 are formed so as to be integrally formed so that the inner surface thereof is located on the same plane as the inner peripheral surface of the nail guide path 3 a in the driver guide 3. And a lower end portion is always slightly protruded from the lower end surface of the distal end member 9 to form a substantially acute angle.

The contact arm 8 has its arm member 10 connected to an operating member such as a trigger for controlling the impact of the driver 2 (in the figure, a rod of a valve controlled by the operation of the trigger). When the guide ridges 11 to 11 of the distal end member 9 are in contact with the lower end portions of the guide slits 7 to 7 and the lower end surface thereof protrudes larger than the lower end surface of the driver guide 3, the arm member 10 operates in the downward movement state. The hitting operation of the driver 2 is prevented without operating the member, and when the tip member 9 is in contact with the surface to be driven and moves upward, the guide protrusions 11 to 11 of the tip member 9 cause the guide slits 11 to 11 of the guide slits 7 to 7 to move. The lower end surface is slightly protruded from the lower end surface of the driver guide 3 while being positioned in contact with the upper end portion.
The arm member 10 is configured to operate the operation member to allow the driver 2 to perform a hitting operation.

Next, the operation of the guide device of the present embodiment configured as described above will be described. When the nailing machine 1 is pressed against the driven surface to be nailed together with the driver guide 3 and the tip member 9 of the contact arm 8, the guide ridge of the tip member 9 of the contact arm 8 is pressed. 11 to 11 are guide slits 7 to 7 of the driver guide 3
Since the contact arm 8 is moved upward, the entire contact arm 8 is moved upward to allow the triggering operation of the driver 2 by the trigger 5a. Then, when the driver 5 hits the driver 5 by pulling in the trigger 5a, the driver 2
Is moved downward in the nail guide path 3a, and the nail T accommodated in the nail guide path 3a is driven out and driven into the surface to be driven.

In this case, the nail TH driven out of the driver guide 3 has its head TH guided on the inner peripheral surface of the nail guide path 3a of the driver guide 3, and the inner periphery of the nail guide path 3a near the distal end. Guide ridges 11 of the distal end member 9 of the contact arm 8 inserted into the guide slits 7 to 7
11 and at the portion deviating from the tip of the nail guide path 3a, only by the inner surfaces of the guide projections 11 to 11 of the tip member 9 until the head TH of the nail T is completely driven into the driven surface. I can guide you.

Accordingly, the nail T is guided and driven in a straight state in the nail guide path 3a. In particular, in the nailing machine 1 configured to drive the nail T by a number of continuous hits by the driver 2, the nail T to be driven is always guided in a straight state until the driving is completed as described above. In this type of nailing machine, the nail driving operation can be performed extremely smoothly by a large number of continuous hits.

Although the nailing machine 1 according to the present embodiment has been described with respect to a configuration in which the nail T is driven by a plurality of continuous hits by the driver 2, a nailing machine in which the nail is driven by a single hit of the driver. May be.

As described above, according to the present invention, a driver guide in which a nail is housed and a driver for hitting the nail is inserted, the driver guide is reciprocally mounted on the driver guide, and A nail driving machine having a contact arm connected to a control member for controlling a hitting operation, wherein a plurality of guide slits having a predetermined length are formed in a lower end portion of the driver guide in an axial direction; The member is provided with a guide ridge which is reciprocally fitted in the guide slit. The guide ridge is formed substantially flush with the inner peripheral surface of the driver guide, and contacts the driven surface. The lower end in contact with the lower end surface of the driver guide is always kept protruding from the lower end surface to form a guide path that is continuous with the inner peripheral surface of the driver guide. In the nail implanted to the guide protrusion of the contact arm of the tip member from its implantation initial to the end it can be reliably guided. This has the advantage of obtaining a nail guiding device which is simple in construction and which can reliably guide the nail to be driven.
