Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle (hereinafter simply referred to as a handle) of a window opening / closing device, and more particularly to a handle which can be folded and stored compactly when not in use, and which can be securely opened when used. It relates to a handle that is locked and easy to use.

[0002]

2. Description of the Related Art For example, a so-called louver window described in Japanese Utility Model Publication No. 7-34133 or Utility Model Registration No. 260
A so-called vertical sliding window described in Utility Model Registration Publication No. 1186 discloses a so-called vertical sliding window. In the case of a louver window, each louver opens and closes synchronously by turning a handle of a window opening / closing device mounted on the indoor side of a window frame. In the case of a vertically sliding window, the handle is rotated to activate the link mechanism, and the window is opened so that the sliding door is taken out of the room.

When these handles are not in use, they protrude into the room and obstruct them. Therefore, the handle of the vertical sliding window or the handle of the window opening / closing device described in Japanese Utility Model Laid-Open No. 5-57246 has two handles. When not in use, they are folded so that they do not protrude into the room, and the appearance is improved.

[0004]

However, the handle of the vertical sliding window has not been designed so that the handle divided into two parts is fixed when used.
In the handle device described in Japanese Utility Model Application Laid-Open No. 5-57246, the two handles are fixed by the click device at the time of use. Therefore, in both cases, the handle caused when the handle is operated does not rotate in the folding direction. The driver must turn the handle with care, which is inconvenient.

[0005] In view of the above, the present invention allows the handle to be divided when not in use and to be folded automatically when one of the handles is caused to be used, so that the handle is automatically locked so that the two can be fixed. It is intended to provide an improved handle.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a base end of a first handle is integrally attached to an outer end of a drive shaft of a window opening and closing device. A second handle having a pair of connecting pieces formed at one end and a knob attached to the other end, with the free end of the first handle being sandwiched between the pair of connecting pieces, A link is connected to the first handle by an operating shaft penetrating the free end of the handle. The operating shaft has a deformed cross-sectional shape, and a flange having the entire shape is integrally formed at one end of the operating shaft. The cross-sectional shape of the through-hole of the operating shaft in the first handle is the same as that of the operating shaft, and the operating shaft is detented in the first handle. Is a circle circumscribing the cross section of the operating shaft. Thus, the second handle can be turned around the operating shaft, and on the other hand, a deformed concave portion which is form-engaged with the flange is formed outside the circular penetrating portion through which one end of the operating shaft passes. The operating shaft is biased in a direction from one end to the other end.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 7, reference numeral 1 denotes a mounting block having a substantially pentagonal cross-sectional shape (see FIG. 7), and the mounting block 1 has a dressing seat 2 whose general shape is shown in FIG. In this state, for example, the louver window is attached to a window frame on the indoor side of the louver window.

In this case, the left side of the mounting block 1 in FIG. 7 is on the side of the sash, and the lower side is on the side of the window frame, as shown in FIG. It is fixed to the mounting plate 4 by the screws 3.

The structure of the window opening / closing device and the relationship between the structure and the mounting block are not the gist of the present invention, so that a more detailed description will be omitted.

As shown in FIG. 7, a drive shaft 6 of a window opening / closing device integrally formed with a worm 5 at the center is rotatably supported in the mounting block 1 as shown in FIG.

At the outer end (right end in FIG. 7) of the drive shaft 6,
A block-shaped first handle 7 having a substantially J-shaped overall shape (see FIGS. 1 and 7) is mounted.

In the embodiment shown, the drive shaft 6 is called by a connecting screw 8 penetrating the base end (the upper end in FIG. 1) of the first handle 7 so that the drive shaft 6 and the first handle 7 are connected. They are integrally joined so that the overall shape is substantially L-shaped.

Then, at the free end of the first handle 7,
As shown in FIGS. 1 and 7, the cross-sectional shape is irregular (in the illustrated embodiment, a part of a circle is cut off by a chord), and a through hole 9 perpendicular to the connection screw 8 is opened. .

In the illustrated embodiment, as shown in FIGS. 1 and 7, the outside of the first handle 7 is covered with a handle cover 11 for decoration.

On the other hand, in the illustrated embodiment, the second handle 12 connected to the first handle 7 is formed by cutting a slightly curved elongated block body into a boat shape from the concave side, and having one end (FIG. 1).
(Right end), the stern and the bottom of the boat are cut away, for example, like a boat, leaving a pair of connecting pieces 13, 13.

As shown in FIGS. 1 and 7, an elongated cylindrical knob 14 is rotatably mounted on the outer surface of the bow of the second handle 12 as compared with the boat.

Since the structure of the knob 14 and the manner of mounting it on the second handle are not the gist of the present invention, a more detailed description will be omitted.

The second handle having the above-described structure has a pair of connecting pieces 13 and 13 and a free end of the first handle 7 with the free end of the first handle 7 sandwiched between the pair of connecting pieces 13 and 13. With the working shaft 15 penetrating the end, the first
It is foldably linked to the handle 7.

As shown in FIG. 1, the operating shaft 15 is a rod having a flange 16 at one end (left end) and a retaining ring groove 17 at the other end. The whole shape is irregular.

In the embodiment shown in the figure, the shape of the operating shaft 5 is such that, as shown in FIG. 1, a rotary shaft having a circular cross section and the entire shape of the flange is formed by a plane parallel to the central axis and an operating shaft portion. It has a shape obtained by cutting a flange.

The cross-sectional shape of the operating shaft is the same as the cross-sectional shape of the through hole 9 of the first handle 7 and is set so as to be slidably fitted thereto.
In the first handle 7, the rotation of the operation shaft 15 is stopped.

On the other hand, the distal end portions of the connecting pieces 13 and 13 of the second handle are slightly thicker, and the cross-sectional shape of the penetrating portions 18 and 18 (see FIG. 1) of the operating shaft 5 formed at the distal end portions of the connecting pieces. Is a circle circumscribing the cross section of the operating shaft 15.

Of the pair of penetrating portions 18, 18, the lower one in FIG.
A recess 19 having the same shape as the flange 16 and a large-sized portion 21 circumscribing the flange 16 are continuously provided (see FIGS. 5 and 6).

On the other hand, an operating shaft 5 formed at the end of the connecting piece
Of the penetrating portions 18, 18 (see FIG. 1), the spring-hung step portion of the operating shaft spring 22 (see FIGS. 1 and 6) serving as a compression coil spring is sequentially arranged outward toward the upper portion in FIG. And a large-diameter portion 21 having the same diameter as the large-diameter portion, for example, are continuously provided.

Then, the operating shaft is inserted from the concave portion 19 side, and the other end is projected outward from the middle diameter portion. The operating shaft spring 22 is wound around this projected portion, and the retaining ring 23 is connected to the other end of the operating shaft. After fitting to the end, a bowl-shaped cap 24 is attached and fixed with, for example, an adhesive.

With the above-described configuration, the operating shaft 15 is urged in the direction from one end to the other end by the elastic force of the operating shaft spring 22, but the flange 16 of the operating shaft is indented 19 or the bottom surface of the large-diameter portion 21. (See FIG. 5).
Will not escape.

The angular relationship between the flange 16 of the working shaft, whose rotation in the circumferential direction is restricted by the first handle 7, and the recess 19 is such that the second handle 12, as shown in FIGS. When completely raised from one handle 7,
The configuration is such that the shapes of the flange 16 and the concave portion 19 match, and the former falls into the latter by the elastic force of the operating shaft spring 22.

When the second handle 12 is tilted on the first handle 7 as shown in FIGS. 2 to 5, the handle according to the embodiment of the present invention constructed as described above, The concave edge is joined to the front surface of the decorative seat 2, and the handle cover 11 of the first handle is inserted between the connecting pieces 13, 13 of the second handle to be compactly folded.

The knob 14 mounted on the free end of the second handle is stored in a knob receiving groove 25 (see FIG. 1) formed on the upper part of the makeup seat 2.

At this time, as shown in FIG. 5, since the shapes of the flange 16 and the concave portion 19 do not match, when the finger is put on the knob 14 and raised, for example, there is nothing to suppress this.

When the second handle 12 is completely raised toward the user as shown in FIGS. 6 and 7, the shape of the flange 16 matches the shape of the recessed portion as described above. As a result, the operating shaft 15 moves upward from below in FIG. 6, and the flange 16 falls into the concave portion 19 so that the two engage in shape.

By this shape engagement, the two members are mutually restrained in the circumferential direction of the operating shaft, that is, both members are locked, and the first and second handles 7, 12 are integrally connected.

In this state, the knob 14 is picked up and the handle 7,
By turning the wheel 12 in a predetermined direction, the user can turn the steering wheel 7, 1
The window opening / closing device can be operated without worrying that the connection between the two is disconnected, and it is truly convenient.

In order to fold the handle again after the use of the handle, the cap 24 (see FIGS. 4 and 6) is pushed, the operating shaft 15 is moved downward in FIG.
Is slightly rotated in the folding direction.

Then, the irregularly shaped flange 16 is inserted into the recess 19.
6 (see FIG. 5), the shapes are disengaged downward in FIG. 6, and the engagement of these shapes is released, so that the second handle can be turned in the folding direction.

Further, since the angle of the concave portion 19 of the same shape with respect to the flange 16 fixed to the first handle 7 changes, even if the finger pressing the cap 24 is separated from the cap, the flange 16 remains in the concave portion 19. Large-diameter part 21 connected continuously
Since the flange 16 does not engage the recess 19 again, the first handle can be further rotated in the folding direction.

Thereafter, the second handle 12 rotates to the folding angle position shown in FIGS. 2 to 5, and the second handle is not locked in the folding angle position of the second handle.

[0038]

As is apparent from the above description, according to the present invention, the base end of the first handle is integrally mounted on the outer end of the drive shaft of the window opening / closing device, and a pair of connecting pieces is provided on one end. The second handle, which is formed and has a knob attached to the other end, penetrates the pair of connecting pieces and the free end of the first handle in such a manner that the free end of the first handle is sandwiched between the pair of connecting pieces. The operating shaft is linked to the first handle, and the cross-sectional shape of the through hole of the operating shaft in the first handle is the same as that of the operating shaft, and the operating shaft is detented in the first handle. The cross-sectional shape of the penetrating portion of the operating shaft in the connecting piece is a circle circumscribing the cross-section of the operating shaft, so that the second handle can rotate around the operating shaft, while one end of the operating shaft penetrates. Flange and shape relationship outside the circular penetration In addition to connecting the irregularly shaped recesses, the operating shaft is urged in the direction from one end to the other end, so simply raising the second handle and turning it to the operating angle position automatically activates it. There is an effect that the flange of the shaft falls into the recessed portion and the first and second handles 7, 12 can be automatically locked.
