In the conventional structure described above, when the guide pin body is made to protrude into the guide rail after the fitting guide member is installed, depending on the depth of the guide rail, the upper surface of the guide pin body may When the fittings come into contact with the inner surface of the rail, and the fittings are opened and closed in this state, there are problems in that the contact causes noise and deteriorates the operability of opening and closing.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a door guide member such as a guide member for fittings that can solve the above-mentioned noise problem and operability problem.

[Means to solve the problem]

The door guide member according to the present invention includes a casing, a guide pin body inserted into the casing in a fixed state and movable up and down, and an upper side of the guide pin body protruding outside the casing. A spring provided inside the casing to be biased in the direction, a fixing mechanism that locks and fixes the position of the guide pin pushed inward of the casing against this spring, and release of the fixing by this fixing mechanism. Further, the fixing mechanism sequentially moves the guide pin body in stages at multiple positions between the two positions, in addition to the maximum retracted position and the maximum protrusion position in the direction of movement. It is characterized by being configured so that it can be locked and fixed to.

[Effect]

In the door guide member of the present invention, the guide pin body is moved against the spring at the maximum retracted position and the maximum protrusion position in the direction of movement, as well as at multiple positions between the two positions. Since it has a fixing mechanism that can be locked and fixed in stages in sequence, and a release mechanism for the fixing mechanism, these mechanisms can adjust the amount of protrusion of the guide pin body into the groove of the guide rail. It can be adjusted in multiple stages so that it is retracted slightly toward the casing after it hits the depths of the groove, while maintaining the guide position in which it is securely locked.

[Effect of idea]

Therefore, according to the present invention, it is possible to adjust the tip surface of the guide pin body so that it does not come into contact with the inner surface of the guide rail when the guide pin body is guided and engaged with the protruding rail. This has the effect of solving problems such as noise generation and deterioration of operability caused by opening and closing of fittings while they are in contact with each other.

A release opening 5 is provided above the center of the mounting plate 2, and adjustment openings 6 are provided below the release opening 5. On the other hand, a guide pin body 7 is provided in the base portion 3 so as to be inserted from above so as to be prevented from coming off and to be movable up and down.

The guide pin body 7 includes a base 8, a shaft 9 projecting upward from the base 8, and a roller 10 rotatably provided at the upper end of the shaft 9.

A coil spring 11 is provided between the bottom surface of the base portion 3 and the bottom surface of the base portion 8 of the guide pin body 7.
is interposed, and the coil spring 11 always urges the guide pin body 7 upward.

Further, a cutout part 12 is formed by cutting out a part of the side surface of the base part 8 of the guide pin body 7, and the side surface of the cutout part 12 has a tooth-shaped multi-stage unevenness in the vertical direction. A locking step portion 13 is provided.

The cutout portion 12 includes a locking piece 14 that can be locked to each of the locking step portions 13 from above, and that is always urged toward the locking step portion 13 so that the locking is realized. is located. Note that the locking piece 14 is biased by an opening 15 provided in the side surface of the base portion 3.
A biasing piece 16 integrally formed with the base portion 3 and located at
It is now being carried out by That is, the locking step portion 13 and the locking piece 14 constitute a fixing mechanism that sequentially locks and fixes the guide pin body 7 in stages when the guide pin body 7 is pushed in against the coil spring 11. ing. The fixing mechanism, that is, the locking between the locking step portion 13 and the locking piece 14 is achieved by forming the unevenness of the locking step portion 13 into an appropriate shape so that an upward force is applied to the guide pin body 7. The lock is effectively engaged when the lock is held in place, and the lock is released when a downward force is applied.
