Description

[Detailed Description of the Invention] The present invention relates to an opening/closing door handle device, and an object of the present invention is to provide a door handle device that is easy to install and that allows the handle to be easily and freely replaced.

The drawings showing the embodiments of the present invention will be described in detail below.
It is composed of a few members: a case 1, a mover 2, a handle 3, and a spring 4.

In the figure, a case 1 is integrally formed of a front wall 1a and a side wall 1b from a synthetic resin material, etc., and a handle shaft hole 5 is formed in a penetrating shape approximately at the center of the front wall 1a. A guide recess 6 for the movable element 2 is formed inside the handle shaft hole 5 by a partition wall 1C91C that is integral with the case 1, and as shown in FIGS. 7, etc., with set screws 8.

Further, the movable element 2 is connected to the guide recess 6 in the case 1.
The guide recess 6 has dimensions corresponding to the width and depth of the guide recess 6, and has a length considerably shorter than that of the guide recess 6. The case 1 is slidably fitted in one direction, and compression springs 4, 4 are interposed between the rear side portion 2a and the side wall 1b of the case 1,
The movable element 2 is elastically biased to one side, that is, to the right in FIGS. 2 and 3.

The movable element 2 also has a handle shaft hole 5 in the case 1.
A handle shaft fitting hole 9 is provided as an elongated hole in the sliding direction in the center corresponding to the handle shaft fitting hole 9, and one longitudinal side of the handle shaft fitting hole 9 has a protruding ridge in the axial direction. The retaining portion 10 is a flat surface having a diameter of 11.

That is, as shown in FIG. 1, the handle shaft fitting hole 9 is resiliently held by the spring 4.4 in such a manner that they mutually bite in the longitudinal direction with respect to the handle shaft hole 5 of the case 1. , approximately half of the handle shaft hole 5 is kept closed by the retaining portion 10.

Further, as shown in FIG. 1, the mover 2 is provided with a recess 12 and a projection 12', respectively, on the side wall thereof facing the guide recess 6 of the case 1 and the partition walls 1c, 1c. The above-mentioned spring 4
, 4 elastically urges the movable member 2 to one side, and the recess 1
2 and the convex portion 12' are preferably displaced from each other because the movable element 2 can be fitted into the guide recess 6 without detaching. The bundle shaft 3b has four notches 13 in its circumferential wall, leaving only a slight portion of the tip 3b', having a length corresponding to the axial inner width of the engaging portion 10 in the movable element 2. At the same time, a grooved line 14 is formed in the center of the flat bottom wall 13a of the cutout recess 13 so as to protrude in the axial direction.

The bundle shaft 3b of the bundle 3 thus formed is positioned in a position opposite to the engaging portion 10 of the mover 2 with the four notches 13 provided on one side facing downward in FIG. Insert it into the bundle shaft fitting hole 9, and then,
If the movable element 2 is slid against the elastic force of the compression springs 4, 4 to align the bundle shaft hole 5 of the case 1 with the bundle shaft fitting hole 9, and at this point the bundle shaft 3b is pushed in,
The bundle shaft 3b is fitted into the bundle shaft hole 5.

After setting the bundle 3 in this way, when the pressure on the movable element 2 is released, the movable element 2 is slid in one direction by the compression springs 4, 4, and the bundle axis fitting hole 9 is moved relative to the bundle axis hole 5.
are different.

That is, the notched recess 13 of the bundle shaft 3b and its grooved line 14
Then, the engaging portion 10 of the movable element 2 and its protrusion 11 are engaged with each other.

Further, since the locking surfaces 13b, 13b are formed at both ends of the notch recess 13 in the axial direction, the bundle shaft 3b that is fitted as described above is held without moving in the axial direction. be done.

The above describes the installation status of the bundle 3 in order, but when removing the bundle 3 installed in this way,
This can be done by the same operation as described above.

Further, as shown in the illustrated example, a window hole 15 is formed in one side wall 1b of the case 1, and an engaging element 16 is provided protruding from the side of the movable element 2 on which the elastic force is applied, and is fitted into the window hole 15. match.

In this case, the width of the window hole 15 is made narrower than that of the four guide parts 6, and as shown in FIG. Shoulders 2b, 2b are provided on both the left and right sides so that they can be brought into relative contact with each other, so that the movable element 2 is prevented from coming off outward by the compression springs 4, and only the engaging element 16 is allowed to pass through the window hole 15. It is set up so that it appears.

With this structure, when the bundle 3 is rotated in the direction of arrow a or a' shown in FIG. In the engaging portion 10 and the notched recess 13 with grooves 14, one corner 13b' of the bottom wall 13a of the notched recess 13 presses against the retaining portion 10 due to rotation of the bundle shaft 3b.

That is, the tip end 3b' of the bundle shaft 3b is fitted into the bundle shaft hole 5 of the case 1, and since it is rotated in a fixed position, the movable element 2 is pressed against the case 1 by the corner part 13b'. Since it slides in one direction against the elastic force of the compression springs 4, 4, the engagement hole 16 can be recessed into the window hole 15.

After doing this, when the rotational force of the bundle 3 is released, the movable element 2, which is elastically biased by the compression springs 4, slides in the opposite direction to the above, and the bundle shaft 3b rotates in the opposite direction. The engaging element 16 then protrudes from the window hole 15 by a predetermined length and then stops.

Further, as shown in FIGS. 2 and 3, if the door frame 17 is provided with a retainer 18 corresponding to the above-mentioned engager 16 or a retaining part such as a recessed hole (not shown), the opening/closing door with a catch can be opened and closed. Can be bundled.

Furthermore, for attachment to the door frame 7, a shaft hole 19 is formed through the frame 7 as shown in FIGS. 2 and 3, and the bundle shaft hole 5 is aligned with the axis of the shaft hole 19. After fixing the case 1 to the frame 7 with the set screw 8, insert the bundle shaft 3b into the shaft hole 19 from the opposite side of the frame 7, and fit it into the mover 2 and the bundle shaft hole 5, respectively, as described above. This is done by

As explained above, according to the opening/closing door bundle device according to the present invention, after the case 1 is fixed to the door stile 7, etc., the bundle shaft 3b is inserted into the shaft hole 19, which is pre-pierced through the stile 7, etc.
is inserted into the bundle shaft fitting hole 9 of the mover 2 and the bundle shaft hole 5 of the case 1, and the notch recess 13 with the grooved line 14 and the engaging part 10 with the protrusion 11 of the mover 2 are connected. Since the bundle 3 is attached by relative engagement, the bundle can be attached to the door simply and easily, and the movable member 2 is moved by the elastic force of the springs 4. The bundle 3 can be easily removed by sliding it against the door frame 7 and aligning the bundle shaft hole 5 of the case 1 with the bundle shaft fitting hole 9 of the mover 2.
By preparing bundles of various gripping shapes in which the bundle shaft 3b is provided with the cutout recess 13 with the grooved line 14, the desired bundle can be freely and easily replaced without being removed from the bundle shaft 3b.

In addition, in the notched recess 13 with the grooved line 14 of the bundle shaft 3b,
The engagement portion 10 with the protrusion 11 of the movable element 2 is connected to the compression springs 4, 4.
Since the bundle 3 is held in place by being elastically biased, even though the bundle 3 can be easily attached and detached as described above, the bundle 3 can be firmly attached and held without coming off or swaying. Furthermore, the movable element 2 can be slid by the rotation of the bundle 3, and the engaging element 16 of the movable element 2 can be retracted from the window hole 15 against the elastic force of the compression springs 4, 4. It can be applied as a bundle, has a simple structure, has very few failure-prone elements, and has excellent durability.
It has practical effects such as being able to be manufactured at low cost.
