Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a handle for opening and closing a window.

2. Description of the Related Art Conventionally, there are windows that are not only open windows but also fall windows. In such a window, as shown in FIG. 7, a connecting rod d having operation pins b facing the window frame c is arranged at a plurality of positions in a rectangular window frame a. By operating the handle, the connecting rod d is moved in the longitudinal direction so as to be locked to the pin receiving e attached to the operation pin b window frame c side, or can be detached to form an open window or a tilted window. is there.

In the handle for moving the connecting rod d in such a window, the operating rod g which rotates integrally with the handle f of the handle and the connecting rod d engage with each other in a rack and pinion system, so that the handle f is moved to 90 °.
The window becomes an opening window or a tilting window when rotated by 180 degrees or 180 degrees.

Problems to be solved by this invention Therefore, unless the grip f is accurately positioned at 90 degrees and 180 degrees, the operation pin b does not engage with the pin receiver d, and the window does not operate correctly.

For such an operation, the applicant has previously developed Japanese Utility Model Application No. 58-172259 (Actual No. Sho 60-80257) and a similar construction to that shown in FIG. A configuration has been devised in which a plurality of recesses h are provided by being separated from each other, a ball j biased by a spring i can be fitted into the recess h, and the operating board g is stopped at an appropriate position.

A problem with such a configuration is that the handle case k becomes large because a space for housing the spring i and the ball j is required. In addition, the ball j or the recessed portion h of the operating plate g may wear due to long-time use and the operating plate g may not be stopped accurately.

Further, in order to eliminate rattling of the handle, it is adopted that the coil spring 1 is housed in the handle case k and the operating board f is pressed. Even in such a configuration, a space for accommodating the coil spring k is required, and the handle case j becomes large in size, resulting in a poor appearance.

Means for Solving the Problems A handle according to the present invention has a non-rotatable positioning plate disposed on the grip portion side of an operating plate, and a projection extending radially from the center on either the operating plate or the positioning plate. A plurality of parts are equally spaced, and a plurality of recesses are also provided on the other side that are also radially extending from the center and are equally spaced so that the projections and recesses can engage with each other and the positioning with the inner surface of the handle case. A disc spring is interposed between the plates to urge the positioning plate toward the operating plate.

Embodiment Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

In the figure, reference numeral 1 is a handle case, and shaft insertion holes 2 are formed in the upper and lower intermediate portions so as to penetrate the front and back surfaces. On the back surface of the handle case 1, a circular storage portion 3 through which the shaft insertion hole 2 passes is recessed. Screw insertion holes 4, 4 are formed at the top and bottom of the handle case 1 so as to penetrate the front and back surfaces.

Reference numeral 5 is an operating panel, which is stored in the storage portion 3 of the handle case 1. The operation board 5 is a disk, and a cylindrical shaft storage portion 6 is provided on one surface so as to project. A shaft storage hole 6a having a rectangular cross section is penetrated from the operation panel 5 to the shaft storage portion 6. Four recesses 7 extending radially from the center are provided at equal intervals (every 90 ° from the center) on the surface of the operating panel 5 on the side where the shaft housing 6 projects. The left and right side portions in the longitudinal direction of the recess 7 are tapered surfaces 8 and 8 whose depth gradually decreases toward the side ends. Teeth 9 are continuously formed on the outer peripheral surface of the operation panel 5 opposite to the shaft housing portion 6. Operating board 5
A prismatic shaft 10 is accommodated in the shaft accommodating hole 6a, and one end of the shaft 10 projects outside the handle case 1.
It is buried at the tip of. The opposite end of the shaft 10 is caulked to fix the operating plate 5.

Reference numeral 12 denotes a positioning plate, which is arranged in contact with the surface of the operating plate 5 in which the recess 7 is provided. A circular hole 13 is formed in the center of the positioning plate 12, and the locking pieces 14 and 1 are vertically arranged.
4 is projected. On the surface of the positioning plate 12 facing the operation plate 5, four convex portions 15 radially extending from the center are provided at equal intervals (every 90 ° from the center). Convex 15
Left and right ends in the longitudinal direction are tapered surfaces 16, 16 whose height gradually decreases toward the side. The positioning plate 12 is non-rotatable because the locking pieces 14 and 14 are locked in the locking portions 17 and 17 formed in the upper and lower recesses of the storage portion 3 of the handle case 1.

A disc spring 1 is provided between the positioning plate 12 and the inner surface of the handle case 1.
Two sheets of 8 are superposed on each other. The disc spring 18 urges the positioning plate 12 toward the operating plate 5.

The teeth 9 of the operation plate 5 are housed in the handle case 1 and mesh with a rack 19 which can move up and down, and the rack 19 moves up and down by the rotation of the operation plate 5. Stoppers 2 are attached to the top and bottom of the rack 19 by using screws 20 on the handle case 1.
1, 21 are fixed, and movement of the rack 19 is restricted.

A back plate 22 is fixed to the handle case 1 with screws. A notch 24 that is long in the longitudinal direction is formed on one side of the back plate 22, and a part of the rack 19 is projected from the notch 24 and the drive plate 25 is attached by a pin 26. The drive plate 25 is connected to a connecting rod (not shown) so that the connecting rod can move along with the vertical movement of the rack 19.

To explain the use state of the handle as described above, when the grip portion 11 is rotated, the operating plate 5 is also integrally rotated, the engagement between the concave portion 7 and the convex portion 15 is released, and when the grip portion 11 is further rotated, the concave portion is rotated at 90 degrees. 7 and the convex portion 15 are engaged with each other, and the rotation of the grip portion 11 is stopped. When the operating plate 5 rotates, the rack 19 meshing with the teeth 9 of the operating plate 5 moves a required length, and the connecting rod moves a required length. In order to further move the connecting rod to open and close it, the grip portion 11 may be further rotated by 90 degrees.

In the illustrated embodiment, the recess 7 and the positioning plate 12 of the operating plate 5
The left and right sides in the longitudinal direction of the convex portion 15 are tapered surfaces 8, 8, 1 respectively.
It is 6,16, and both can be engaged and released smoothly.

Since the positioning plate 12 is biased toward the actuation plate 5 by the disc spring 18, the grip part 11 is pulled toward the handle case 1 side via the shaft 10 connecting the actuation plate 5 to the grip part 11. Therefore, the grip 11 does not rattle.

The handle according to the present invention has the above-described structure, but the concave portion 7 is used as a positioning plate and the convex portion 15 is used as the operating plate 5 in addition.
It is also possible to form it.

Further, the handle according to the present invention can be used for various windows such as a full turn window and a sliding window.

Effects of the Invention Since the invention has the above-mentioned configuration, the following effects can be obtained.

A) A plurality of protrusions radially extending from the center are equally spaced on one of the operating plate and the positioning plate, and a plurality of recesses radially extending from the center are equally spaced on the other. Since the grip and the recess can be engaged with each other, when the grip is rotated and the operating plate is rotated, the projection and the recess are engaged with each other at an appropriate position to stop the movement of the grip, and the accurate movement amount of the connecting rod can be obtained. Can be secured, and the coupling pin and the pin receiver can be accurately locked and released.

(B) Even if some of the protrusions and recesses wear due to the engagement of multiple protrusions and recesses, the remaining protrusions and recesses will engage accurately, and the rotation angle of the grip will be maintained even after long-term use. Can be stopped accurately.

(C) Unlike the conventional handle, since the ball is not pressed against the operating plate by the spring, a space for storing the ball and the spring is not required in the handle case, the handle case becomes small, and the appearance is good.

D.Because a disc spring is interposed between the positioning plate and the inner surface of the handle case to urge the positioning plate toward the operating plate, the grip that is connected to the operating plate by the shaft is pulled toward the handle case, and the rattling of the grip occurs. Does not occur. Further, since the disc spring is used, the storage space may be small, the handle case is small, and the appearance is good.
