Abstract

PURPOSE:To provide a structure not damaging a guide shaft even when a carriage is fixed at the time of transport and capable of fixing and releasing the carriage by the one-action operation of a user. CONSTITUTION:A spring 4 is arranged so that the fixing member 3 guided by a shaft 8 is engaged with the opening 10 of a frame 2 and a user applies force in the direction reverse to that of the force applied at the time of locking. A carriage 1 is attached to a guide shaft 5 by a bearing 6 and the shaft 7 engaged with the fixing member 3 flies out. When force is applied to the fixing member 3 in the direction shown by an arrow 18, an elastic engaging piece 12 is moved in the direction shown by an arrow 19 to be engaged with the shaft 7. At this time, the positional shift of the carriage can be corrected by the taper 13 of the fixing member 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for fixing a reciprocating carriage as needed during transportation.

[0002]

2. Description of the Related Art As a conventional technique, a fixing structure for fixing a carriage and a frame with a screw is known as a method for fixing a carriage that reciprocates.

[0003]

However, in the conventional fixing structure, when the carriage is moved by being guided by the guide shaft, the carriage is fastened to the frame by the screw, so that the guide shaft bearing formed in the carriage is used. There was a problem that the guide shaft was damaged and the carriage could not move smoothly. In addition, in the case of fixing with a screw, a tool is often required to release the fixing, and the user has a lot of trouble because the screw is rotated and removed. Also, if it is necessary to frequently repeat the fixing and the releasing, the operability is significantly deteriorated. Further, there is a problem that the removed screw may be lost.

Therefore, in order to solve the above-mentioned conventional problems, the present invention fixes the carriage such that the guide shaft is not damaged even when the carriage is fixed during transportation and the carriage can be smoothly reciprocated. In addition, it is also an object of the present invention to provide a fixing structure that allows the user to fix and release the carriage with one touch, improving operability.

[0005]

The fixing structure of the present invention is a fixing structure for fixing a reciprocating carriage to a frame as necessary, in a direction substantially perpendicular to the direction of the force applied to the fixing member. It is characterized in that the engaging portion with the carriage moves to fix the carriage.

[0006]

1 is a specific embodiment of the present invention, in which a carriage 1 is composed of a shaft 7 and a bearing 6, and a guide shaft 5 passes through the bearing 6 to guide the carriage 1. . The frame 2 includes an opening 10 and an opening 11, a shaft 8 and a dowel 9.
And supports the guide shaft 5 and the like. Fixed member 3
Is formed of one-piece plastic and is mounted so as to sandwich the frame 2, and 14 openings are engaged and guided by the shaft 8 and are also guided by the openings 10 of the frame 2. One end of the spring 4 is hooked on the opening 11 of the frame 2, and the other end is hooked on the opening 15 of the fixing member 3. The state of FIG. 1 is
The fixing member 3 is not engaged with the shaft 7 of the carriage 1 in the state where the fixing of the carriage 1 is released. In this state, the fixing member 3 is pushed in the direction of the arrow 16 by the spring 4, but the projection 17 of the fixing member 3 contacts the dowel 9 of the frame 2 and the fixing member 3 is locked.

FIG. 2 is a diagram showing the configuration in the depth direction of FIG. 1, in which the fixing member 3 is engaged so as to sandwich the frame 2, the carriage 1 is attached to the guide shaft 5 by the bearing 6, and the shaft 7 is attached. It is protruding from the carriage 1.

In FIG. 3, the fixing member 3 of the present invention is a carriage 1.
The fixed member 3, which is guided by the opening 10 of the frame 2 and the shaft 8 while being engaged with the shaft 7 of the carriage 2, bends before the elastic piece 12 completely enters the shaft 7 of the carriage 1, When completely entering, it is bite and locked. In this case, the moving direction of the elastic piece 12 portion of the fixing member 3 is an arrow 19 which is close to a right angle to the arrow 18 of the direction of the force applied to the fixing member 3, and is also close to a right angle to the arrow 20 of the moving direction of the carriage 1. Therefore, even if some force is applied to the carriage 1, the elastic piece 12 of the fixing member 3 cannot be disengaged from the shaft 7 of the carriage 1. Further, there is a taper 13 near the elastic piece 12 of the fixing member 3, and even if the carriage 1 is slightly deviated from the fixed position, the taper 13 moves and fixes the shaft 7, and thus the carriage 1, to the fixed position. When the carriage 1 is not near the fixed position, the fixing member 3 returns to the state of FIG. 1 by the force of the spring 4. As a result, when the user tries to fix the carriage without noticing that the carriage 1 is not near the fixed position, when the user releases his / her hand, the fixing member 3 returns to the release position, so that the user can fix the carriage at the fixed position. You can know that there is no, and you can prevent operation mistakes.

FIG. 4 is a view of the embodiment of the present invention to which a user's operation member is added, as viewed from the same direction as FIG. 2, in which a concave portion 21 of the fixing member 3 has a columnar key 22 operated by the user. The shape 23 is engaged with some clearance. The key 22 has a user operation unit outside the exterior member 24. When the user slides the key 22, the fixing member 3 moves to fix the carriage 1. Further, when the user slides the key in the opposite direction, the fixation of the carriage 1 can be released.

[0010]

As described above, according to the fixing structure of the present invention, even if the carriage is fixed, the guide shaft is not scratched, and the carriage is fixed in such a state that it can smoothly reciprocate. In addition, the carriage can be fixed and released with one touch without using a tool, which has the effect of improving operability.
