JPH0634525Y2 - Tightening handle with stopper for sliding door - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a tightening handle used for a sliding door sash.

[Prior Art] Conventionally, it has been known that a handle in a sash has a mechanism for stopping the handle by itself when the handle rotates by a certain angle. It was provided with a stopper mechanism.

[Problems to be solved by the invention] If a stopper mechanism is provided inside the rotation shaft core of the handle, the tip of the handle will shake greatly due to a slight error in the stopper mechanism, especially when the handle is long and large. I will end up. Moreover, since a large moment acts on the shaft core, the stopper mechanism is easily damaged.

Especially when the sash becomes large and the shoji that opens and closes becomes heavy,
If the handle is not enlarged, opening and closing will not be easy.
That is, the handle inevitably becomes large in order to perform a light closing operation on the shoji screen. Therefore, the durability problem as described above occurs, but in addition, if the handle rotates 180 ° when it is locked and unlocked and the handle rotates 180 ° or more, the hand holding the handle is It is not appropriate for safety or operation because it hits the frame material.

[Means for Solving Problems] The present invention is intended to solve the above problems, and the handles can be reliably stopped at symmetrical positions of 180 ° so that the handles can be locked or unlocked. The handle is fixed, and the handle is used as a pull tab, so that the handle is easy to operate and there is no problem in strength.

[Embodiment] Explaining an embodiment with reference to the drawings, FIG. 1 is a partially cutaway front view, and FIG. 2 is a cutaway side view of the same portion. In the figure, reference numeral 1 denotes a mounting seat, which is mounted on a vertical frame of a shoji screen, for example. A handle 2 is rotatably attached to the center of the attachment seat 1. A pinion gear 3 is fixed to the inner end of the mounting seat 1 of the handle 2 and rotates as the handle 2 rotates. The pinion gear 3 meshes with the rack gear 4 having the shape shown in FIG. A lock plate 5 is provided upright on the rear surface of the rack gear 4, and a slit 6 provided on the rear surface of the mounting seat 1.
It is projected more into the vertical frame.

Further, on the surface of the mounting seat 1, there is provided a lock pin 7 biased by a spring 8 in a constantly protruding state at a symmetrical position with respect to the center of rotation of the handle 2. The lock pin 7 is in a state in which one end of the upper end is obliquely cut off as shown in FIG.

At a position corresponding to the lock pin 7 of the handle 2, a push pin shaft 11 is constantly urged in a retracted state by a spring 9 in a protrusion 10. Reference numeral 12 is a pressing portion of the push pin 11.

The tightening handle with stopper having such a structure is attached to the vertical frame 14 of the shoji 13 as shown in FIG.

If the position of the handle 2 shown in FIG. 1 is the locked position,
In order to unlock it, first, the handle 2 is grasped, and the push portion 12 is pushed with the thumb, for example, and the push pin shaft 11 is pushed. Then, the lock pin 7 is pushed against the elastic force of the spring 8 and the locked state is released. Then, the handle 2 is rotated 180 °.
As shown in FIG. 4, when the protrusion 10 having the push pin shaft 11 abuts the lock pin 7 on the other side, the lock pin 7 is repelled by the spring 8 along the slope of the lock pin 7. When the push-in shaft is completely pushed in, the elastic force of the spring 8 works and the lock pin 7 pushes the push pin shaft of the protrusion 10.
It fits into the 13 storage holes and locks.

When the handle 2 rotates 180 °, the pinion gear 3
Also rotates at the same time to drive the rack gear 4 and lock plate 5
Move to the unlock position and unlock simultaneously.

Since the handle 2 is fixed at two places apart from the rotating shaft and the lock position, the fixed state is stable, and the handle 2 can be used as it is as a pull tab.

[Advantage of the Invention] In the present invention, since the stopper mechanism is exposed to the outside of the vertical frame or the like and is provided at a position away from the rotation axis of the handle, the stopper mechanism can be made large and durable, and the handle can be used. Can be reliably stopped at the 180 ° rotation position. In addition, the operability is good because the stop mechanism can be disengaged simply by pushing the push pin for unlocking operation.

Since the stopper mechanism is installed at a symmetrical position of 180 ° up and down, the handle is fixed in either the locked position or the unlocked position unless the push pin shaft is pressed, and it can be used as a pull tab.

Further, even if the handle is pulled in the horizontal direction and the handle does not rotate or grind, even a heavy shoji with a large window can be used as a pull handle and is practical.

Claims (1)

[Scope of utility model registration request] Claim: What is claimed is: 1. A tightening handle having a mechanism for rotating a handle to rotate a pinion gear at the front end of the pinion gear, and a rack gear meshing with the pinion gear to linearly move the handle. The pin shaft is attached, and the lock pin, which is always biased in the protruding state, is provided on the other seat at symmetrical positions about the rotation center of the handle, and the lock pin is fitted into the storage hole of the push pin shaft at each position. A tightening handle with a stopper for sliding doors, which is characterized in that it is made possible.
