Abstract

PROBLEM TO BE SOLVED: To make slipping-off of a sliding door from the guide grooves of a head jamb and a sill hard to occur by arranging expansible projecting fittings at two places or more at specified places at the upper end section of the sliding door slid and moved in the guide grooves. SOLUTION: Projecting fittings 12 are fitted at several places at the upper end section of a sliding door 11. The projecting fitting made of a metal has an upper disk section 13, a rod section 15 with a flange 14 continuously connected at the lower end of the disk section 13, a spring 16 pushing the disk section 13 by utilizing the flange 14, and a housing 17, in which these members are housed, and the disk section 13 is pushed up upwards by the spring 16 at all times. When the sliding door 11, to which the projecting fittings 12 are set up, is fitted to a head jamb 19, to which a specified guide groove 18 is formed, the disk sections 13 of the projecting fittings 12 mounted at the upper end section of the sliding door 11 are projected upwards, and the sliding door 11 is slid and moved under the state, in which the upper bottom of the guide groove 18 is pushed. Even when the head jamb 19 is distorted by an earthquake, etc., and the upper section of the sliding door 11 is slipped off from the guide groove 18, the projecting fittings 12 are difficult to be slipped off from the guide groove 18, thus preventing the slipping-off of the sliding door.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device used in general houses and the like.

[0002]

2. Description of the Related Art Sliding doors are mounted so as to slide left and right in guide grooves formed in upper and lower sills and sills which form upper and lower door frames.

[0003]

However, if the upper and lower sills or sills are distorted due to an earthquake or the like, the sliding door itself may come out of the guide groove of the upper sill and fall down. The present invention has been made in view of the above circumstances, and an object thereof is to provide a sliding door device in which the sliding door itself does not easily come off the guide groove of the kamoi even if the kamoi or the sill is distorted due to an earthquake or the like.

[0004]

A method according to the above-mentioned object.
The sliding door device described is a sliding door device in which upper and lower portions of the sliding door are slidably mounted in guide grooves of the upper and lower sills and sills, and the sliding door device can be expanded and contracted to a predetermined position of an upper end portion of the sliding door. At least two protruding metal fittings are arranged. The present invention is also applicable to the case where the protruding metal fittings are contracted and the whole of the fittings can be fitted into the upper end portion of the sliding door, and when the protruding metal fitting is left from the upper end portion of the sliding door within a range that does not hinder the opening and closing of the sliding door. . It is also possible to attach a wheel to the upper end of the protruding metal fitting, which allows the sliding movement of the sliding door to be carried out more smoothly.

[0005]

In the sliding door device according to the first aspect of the present invention, at least two projecting metal fittings which can be expanded and contracted are arranged at predetermined positions on the upper end portion of the sliding door. Therefore, when the sliding door is mounted in the Kamoi, the projecting metal fitting is installed. Can be done with the retracted. Once the sliding doors are installed in the upper and lower kamoi and the guide grooves of the sill, the protruding metal fittings stretch and press the upper base of the guide grooves of the kamoi, so even if the kamoi or the sill is distorted and deformed, the sliding doors will remain. It will be difficult to come off. Further, in a normal use state, since the protruding metal member moves while sliding on the upper bottom of the guide groove of the Kamoi, the sliding door can be opened and closed without any trouble.

[0006]

Therefore, the sliding door device according to claim 1 is
Even if the Kamoi is distorted due to an earthquake or the like, the sliding door does not easily come off the guide groove, so the safety is extremely high.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Next, referring to the attached drawings, an embodiment in which the present invention is embodied will be described to provide an understanding of the present invention. 1 is a cross-sectional view of the sliding door device according to the first embodiment of the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is a perspective view of the sliding door device according to the second embodiment.

As shown in FIGS. 1 and 2, the sliding door device 10 according to the first embodiment of the present invention is provided with protruding metal fittings 12 at several positions on the upper end portion of the sliding door 11. The protruding metal fitting 12 is made of metal such as iron, stainless steel, aluminum, or brass, and has an upper disk portion 13, a rod portion 15 with a flange 14 connected to the lower end thereof, and a rod portion using the flange 14. A spring 16 that pushes 15 up,
There is a mounting housing 17 for accommodating them, and the disc portion 13 is always pushed upward by the spring 16.

Therefore, when the sliding door 11 to which the protruding metal fitting 12 is attached is attached to the kamoi 19 in which the predetermined guide groove 18 is formed, the protruding metal fitting 12 attached to the upper end of the sliding door 11, specifically, the disk portion. 13 projects upward and slides while pressing the upper bottom of the guide groove 18. Even if the Kamoi 19 is distorted and the upper portion of the sliding door 11 is disengaged from the guide groove 18 due to an earthquake or the like, the protruding metal fitting 12 is difficult to disengage from the guide groove 18, and thus the sliding door 11 is less likely to fall.

FIG. 3 shows a sliding door device according to a second embodiment of the present invention. As shown in the drawing, the protruding metal fitting 20 has a rectangular shape, and is pushed by a spring (not shown) to the upper end of the sliding door 21. It is designed to project upward from the part. By thus forming the protruding metal fitting 20 into a rectangular shape, the upper end portion of the sliding door 21 can be widely used and the protruding metal fitting 20 having sufficient strength can be attached.
