Description

Detailed Description of the Invention

TECHNICAL FIELD OF THE INVENTION The present invention relates to a so-called whitco as a fitting, particularly a fitting for opening and closing windows, and more particularly, to an improvement of a whitco that can be opened and closed in multiple stages.

[Prior Art] Conventional Whitoco generally
A frame attachment member, a fitting attachment member, and a stay interposed between the members, each of which is connected by a hinge. In particular, the hinge connecting the frame attachment member and the fitting attachment member is a guide provided in the frame attachment member. It has a structure that slides in the hole.

However, with this structure, it becomes stable only when the fitting, that is, the window is closed and opened.
Not only is it impossible to fix it on the way, but it is necessary to attach a locking device (for example, a catch lock) to the frame member and the joiner member even in the closed state, which requires a lot of time and effort for attachment. There are drawbacks as well as economic problems.

[Technical Problem of the Present Invention] The present invention has been made in view of the above circumstances, and an object thereof is to obtain a novel whitco in which opening and closing of fittings are performed in stages and wobble is not caused. Subject)).

[Configuration and Operation of the Present Invention] The fitting opening / closing fitting of the present invention has the following configuration (technical means) in order to achieve the above object. That is, the frame-side attachment member 1 attached to the frame, the fitting-side attachment member 1 attached to the fitting
0, and an opening / closing fitting for fittings, which is composed of stays 15 interposed between the frame-side mounting member 1 and the fitting-side mounting member 10, each of which is joined by a hinge. A guide hole 2 is bored, and one or a plurality of sets of projecting portions 3 and 4 facing the guide hole 2 are projected on the surface of the frame-side mounting member 1, and the frame-side mounting member 1 and the fitting side are provided. Hinge 20 for connecting with the attachment member 10
Is slidable along the guide hole 2 and engaged and fixed by the protrusions 3 and 4, and is capable of overcoming the protrusions 3 and 4 by an elastic force of a spring member.

With this construction, the fitting opening / closing fitting of the present invention has the following effects. When the fitting is released from the closed state, the sliding hinge 20 descends through the guide hole 2, but the sliding hinge 20 overcomes the protrusions 3 and 4 by the elastic force of the sliding hinge 20 and is locked by the next protrusions 3 and 4. Stop. As the fittings are opened,
The sliding hinges successively pass over the protrusions 3 and 4 and are locked by the protrusions so that they can be opened in multiple stages.

[Effects of the Present Invention] The fitting opening / closing fitting of the present invention has the above-mentioned configuration and functions, and therefore has the following unique effects. By providing the protrusions of the guide holes in an appropriate number of steps, the fitting can be gradually opened to a predetermined angle. Since this metal fitting has a hinge function, it is not necessary to use a hinge, and the effect is economically great.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the Wheatko H of the present invention. Here, 1 is a frame-side mounting member (hereinafter abbreviated as "frame-side member"), which is made of steel material having a groove-shaped cross section, and is formed into a hollow structure 1d by a front-side member 1a, a back-side member 1b, and both-side members 1c. Has become.

A vertically long guide hole 2 is formed in an upper portion of the front side member 1a of the frame side member 1, and the guide hole 2 is formed by punching.

Reference numerals 3 and 4 are an upper projection and a lower projection, which project toward the front side facing the guide hole 2, and the projections 3 and 4 are formed by pressing. Then, a sliding hinge, which will be described later, slides in the guide hole 2 while engaging with the protrusions 3 and 4. In this embodiment, two sets of protrusions are provided, but it is needless to say that only one set (in this case, the opening / closing operation has one step) or three or more sets (opening / closing operation has three steps or more) may be provided. is there.

Reference numeral 5 is a screw hole for mounting the frame, which is formed in the frame-side member 1. Reference numeral 6 is a pin hole for a fixed hinge described later.

Reference numeral 10 denotes a fitting-side attachment member (hereinafter abbreviated as "fitting-member side member"), which is made of steel and has a bent portion 10a formed above it. The fitting-side member 10
A pin hole 11 for a sliding hinge is bored in the upper part of and a pin hole 12 for a fixed hinge is bored in the lower part. Reference numeral 13 is a screw hole for attaching a fitting, which is formed in the fitting-side member 10. It goes without saying that the screw hole 13 is also formed in the bent portion 10a.

Reference numeral 15 is a stay. Pin holes 16 and 17 for fixed hinges are formed at both ends of the stay 15.

The frame side member 1, the fitting side member 10 and the stay 15 are rotatably connected by a hinge mechanism. That is, 20 is a sliding hinge that connects the frame-side member 1 and the fitting-side member 10, and 30 is the fitting-side member 10.
Is a fixed hinge that connects the stay 15 to the stay 15, and 40 is a fixed hinge that connects the frame-side member 1 and the stay 15.

The sliding hinge 20 includes a pin 21 and a washer 2.
2 and a spring member 23 (see FIG. 4). These members are usually made of metal, but the washer 22 is preferably made of a hard and abrasion-resistant synthetic resin.

The sliding hinge 20 is mounted as follows. That is, the pin 21 is inserted from the rear surface of the frame-side member 1 toward the guide hole 2, the flange 21a is pressed against the rear surface of the front-side member 1a, and then the washer 22, one or more disc springs 23 are attached to the pin 21. It is sequentially fitted into the joist 21b. The crimped portion 21c of the pin 21 is inserted into the pin hole 11 of the fitting-side member 10, and the crimped portion 21c is crimped so as not to come out of the pin hole 11.

It is a matter of course that the spring member 23 can be appropriately selected and used in place of the disc spring, such as a wave washer, a spring washer, and a coil spring, which have a spring effect. Further, the retaining of the pin 21 may be replaced by caulking, and other appropriate means (for example, ring retaining) may be used.

As the fixed hinges 30 and 40, normal hinges which allow only rotation between members are used.

Next, the mode of use of this embodiment will be described. (1) When the fitting is closed (see FIG. 2) When the fitting is closed, the frame side member 1, the fitting side member 10 and the stay 15 are aligned in a straight line. At this time, the sliding hinge 20 is located at the uppermost position of the guide hole 2.

(2) During opening When the handle of the fitting is grasped and pushed (or pulled), the sliding hinge 20 starts to descend downward. When the fitting is further pushed, the sliding hinge 20 reaches the first projection 3 of the guide hole 2, but since the sliding hinge 20 is provided with the spring member 23, the washer 22 is It will get over the protrusion 3. Then, the sliding hinge 20 gets over the projection 3 and reaches between the projection 3 and the projection 4, and the washer 22 is sandwiched between the projections 3 and 4, so that the fitting-side member 10 and thus the fitting are It will be fixed.

(3) Full opening of fittings (see FIG. 1) By pushing (or pulling) the fittings as described above, the washers 22 of the sliding hinges 20 are successively engaged between the protrusions of the guide holes 2. The fittings can be opened at a predetermined opening angle in multiple stages. When the sliding hinge 20 reaches the lowermost end of the guide hole 2, further opening of the fitting is stopped.
