BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a switch such as a door according to the present invention.

FIG. 1 is an explanatory perspective view showing a mounted state of a switch according to an embodiment of the present invention, FIG. 2 is a partially cutaway perspective view of an outer cylinder of FIG. 1, and FIG. FIG. 4 is a partially cutaway perspective view and FIG. 4 is a cross-sectional explanatory view showing a state before and after locking of a main part of the switch of FIG.

The switch 1 shown in FIG. 1 comprises an outer cylinder 2 and an insertion member 3 slidably inserted into the outer cylinder 2. The outer cylinder 2 is attached to a window frame F or the like by an attachment member 4, and the insertion member 3 is attached to a window W or the like by an attachment member 5. When the window W is opened, the insertion member 3 becomes the outer cylinder 2
When the insertion member 3 is fully extended, the protruding piece 11 (see FIG. 3) provided on the insertion member 3 is engaged with the engagement portion 12 provided on the outer cylinder 2. The window W is fully opened and locked by being fitted into (see FIG. 2). For this reason, the insertion member 3 does not shrink unless the window is pushed in a direction to close the window with a certain force. Moreover, immediately before the window W is fully opened, the insertion member 3 is decelerated by the brake portion 19 (see FIG. 2) of the outer cylinder 2 described later, so that no loud noise is generated when the window W is fully opened.

As shown in FIG. 2, the outer cylinder 2 is a long member, and has a flat, substantially C-shaped cross section with an open upper side in the drawing. The shape of the cavity inside the substantially C-shaped cross section is similar to and slightly larger than the sliding member 13 attached to the rear end 3 c (see FIG. 3) of the insertion member 3. It can slide smoothly. A receiving member 14 is fitted to the distal end 2 a of the outer cylinder 2. The receiving member 14 is a square tubular member made of synthetic resin, and the shape of the cavity inside the square tubular shape is similar to the cross-sectional shape of the main body 3a of the insertion member 3, and is slightly larger. The body 3a of the member 3 can be slid smoothly. Further, a circular hole 15 for rotatably mounting the mounting member 4 is formed in the rear end 2b of the outer cylinder 2. The outer cylinder 2 is preferably formed by press working with a metal such as iron, stainless steel, or aluminum to maintain sufficient strength and to be manufactured at low cost.

As shown in FIG. 2, an engagement plate 17 for forming a concave engagement portion 12 is provided on the bottom surface 2c of the outer cylinder 2 along the longitudinal center line.
8 is attached by swaging. This attachment can be made by other methods such as welding or bonding. Further, the engagement plate 17 may be formed integrally with the outer cylinder 2. For example, the engagement plate 17 may be formed by making a hole corresponding to the engagement portion 12 in the bottom surface 2c of the outer cylinder 2 and then pressing the bottom surface 2c.

Further, as shown in FIG. 2, a brake portion 19 is formed on the bottom surface 2c of the outer cylinder 2 at a position behind the engagement plate 17 (closer to the rear end 2b).

The brake portion 19 is formed integrally with the outer cylinder 2, specifically, is formed so as to protrude by about 1 to 2 mm by pressing the bottom surface 2 c of the outer cylinder 2 inward. If the brake part 19 is formed integrally with the outer cylinder 2, the brake part 19 is easy to process, requires a small number of parts, and has excellent mechanical properties such as impact resistance and wear resistance. preferable.

Although the brake section 19 has been described in the present embodiment as an example of being integrally formed with the outer cylinder 2, the present invention is not limited to this. May be adopted.

For example, steel,
A brake unit made by fixing a thin plate member (thickness of about 1 to 2 mm) of resin or the like by welding, bonding, or the like may be employed. In this case, since a thin plate made of a material different from that of the outer cylinder 2 can be selected, it is possible to obtain a brake unit having both an optimal braking effect and mechanical characteristics.

When a brake portion made of a plate-like member such as the thin plate is employed, if at least a part of the periphery of the brake portion, for example, the entire periphery is chamfered, a sliding member 13 of an insertion member 3 described later can be used as an outer cylinder. 2 from the bottom 2c to the brake 1
9 is preferable because it can be smoothly moved to the upper surface.

The insertion member 3 comprises a main body 3a having a flat, substantially C-shaped cross section with its lower side opened in FIG. 3, and a sliding member 13 attached to its rear end 3c. The sliding member 13 is made of a synthetic resin, is in contact with the bottom surface 2 c of the outer cylinder 2, and is slidably supported inside the outer cylinder 2.
Further, the engagement plate 17 is arranged along the lower opening 3b of the main body 3a. Further, the size of the cross section of the main body 3a is adjusted so that the main body 3a does not come into contact with the outer cylinder 2.
Is formed slightly smaller than the internal cavity of the outer cylinder 2 and is supported by a receiving member 14 provided at the distal end 2 a of the outer cylinder 2. A circular hole 16 for rotatably mounting the mounting member 5 is formed on the distal end side of the insertion member 3. Insertion member 3
Also, similarly to the outer cylinder 2, it is preferable to form it by press working with a metal such as iron, stainless steel, or aluminum while maintaining sufficient strength and manufacturing at low cost.

A leaf spring 20 is attached to the inside of the main body 3a of the insertion member 3 by caulking a rivet 21 downward in FIG. This attachment can also be performed by other methods such as welding and bonding. Also, leaf spring 2
0, a protruding piece 11 is attached downward, and one end 17a (see FIG. 2) of an engagement plate 17 provided on the outer cylinder 2 causes a surface 20a of the leaf spring 20 to be fixed.
(The surface on which the projecting piece 11 is provided) is pressed, and the projecting piece 11 is invited into the engaging portion 12 while the bias is released. At this time, the projecting piece 11 may slide on the bottom surface 2c of the outer cylinder 2, but is preferably moved slightly away from the bottom surface 2c of the outer cylinder 2 in order to reduce frictional noise. . In the present embodiment, as shown in FIG. 4A, the protruding piece 11 is arranged so as not to hit not only the bottom surface 2c but also the brake portion 19. The bottom 2
Even when sliding on c, since the bottom surface 2c is a flat surface (not a cut surface), scratches are less likely to occur on the sliding portion, and there is almost no friction noise.

It is preferable that the leaf spring 20 is manufactured from stainless steel, cast material, synthetic resin or the like from the viewpoint of abrasion resistance.

As shown in FIG. 4, in the switch according to the present embodiment, the brake portion 19 is provided on the bottom surface 2 c of the outer cylinder 2.
As shown in FIG. 4A, immediately before the window W is fully opened when the window W is fully opened,
When the sliding member 13 of the insertion member 3 first contacts the brake portion 19 and moves while rubbing against the brake portion 19, the insertion member 3 is subjected to so-called friction braking and decelerated. Thereafter, as shown in FIG. 4B, the protruding piece 11 moderately decelerated generates a loud noise with respect to the concave engaging portion 12 of the engaging plate 17 at a predetermined speed or less. It can be engaged quietly without the need.

Further, in the present embodiment, in order to reliably lock the insertion member 3 at a timing slightly delayed after the engagement of the projection 11 and the engagement portion 12, the engagement protrusion 23 is provided.
(See FIG. 3) and a second locking mechanism including a contact portion 22 (see FIG. 2).

More specifically, as shown in FIGS. 2 and 3, the locking mechanism is provided near the rear end 3c of the insertion member 3 (the main body 3).
(a back side of the upper surface of a), and an abutting portion 22 provided in the vicinity of the front end portion 2a of the outer tube 2 on the upper surface side of the outer tube 2 in a stepped manner. In addition, the contact portion 22 is pulled when the insertion member 3 is pulled slightly forward from a position where the leaf spring 20 engages with the engagement portion 12 of the engagement plate 17 (see FIG. 4B). The contact portion 22 is disposed at a position where the contact portion 22 contacts the engagement protrusion 23. Therefore, even if the insertion member 3 further attempts to move out of the state shown in FIG.

The switch such as the door according to the present invention is mounted on the lower surface of the window frame F as shown in FIG.
Can be mounted on top of window frames and frames.

[0031]

According to the present invention, generation of a loud noise can be prevented even when a door, a window or the like is vigorously opened. Therefore, since the door and the window can be opened quietly, it is suitably used in an apartment house or at night.
