Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to external gates for buildings, particularly garage doors.

The prior art revolving lift door had the disadvantage that it was not well known as Japanese Patent Publication No. 57-53507. Also, it is possible that the door is used only as an approach to a house or as a garage door, but there is the inconvenience of having to open and close the garage door to a large extent just for people to enter and exit.

Problems to be Solved by the Invention It is an object of the present invention to improve the above-mentioned drawbacks, expand the application conditions of construction sites, and provide convenience for opening and closing doors for both vehicles and people.

Means and Embodiments for Solving the Problems The configuration of an embodiment of the rotating lift door according to the present invention will be described with reference to a drawing. Two shaft supports 41 and 42 are arranged on the axis X, and one end 21a and 22a are supported by the two shaft supports 41 and 42,
Consists of two support arms 21 and 22 that are rotatable in a plane intersecting the axis In the rotary lift door, the shape of the support arms 21 and 22 when the door is closed is concave when viewed from below, and the maximum height h of the concave surface is a height that corresponds to the large island, and the shape of the support arms 21 and 22 when the door is closed is made to be a concave shape, and the maximum height h of the concave surface is a height that corresponds to the large island. The support arms 21 and 22 are connected to each other at a height h corresponding to the large island, the upper t[1a, and the lower 1b 1b close to the ground surface S, and from a part of the upper stile 1a to the upper stile 1a. suspend the short center frame 1c, and connect the center 1c and the above lower +
The main surface of the door 1 is formed between the door 1b and the door 1b. In addition, the support arms 21 and 22
It counteracts the gravitational moment exerted by the stopper that limits the rotation stroke of the door to approximately 90° (between when the door is vertically closed and when the door is opened horizontally) and the rotating parts such as the door l and support arms 21 and 22. A biasing spring is also provided, but it is not shown for the sake of clarity. It is optional to provide reinforcing cheeks at the bent portions of the support arms 21 and 22. A small door is arranged in the missing part of the middle stile 1c along with the main surface of the door 1. Further, 31 and 32 are columns that support the shaft supports 41 and 42 on the ground surface S, and the reference numeral 7 used in this specification is
The second digit 2.1 indicates the left and right sides of the support arm system, and although some are not shown, they appear the same as those of other systems.

Function: Since the present invention has the above-described configuration, it is possible to obtain a structure as a door that is large enough to fit the large island between the top panel 1a and the bottom stile 1b. Gates are usually 1 person high, except in the case of free-standing garages.
/2 in many cases, so the middle stile IC is short enough to match this height.
The main surface of the door 1 is formed between the middle stile 1C and the lower stile 1b.

The area near the missing end of the middle stile 1c is suspended from the upper stile 1a. Therefore, normally one door or a small sliding door is closed and locked, and in this state, the door 1 with the widest frontage is closed by one lift and the car is closed. I'm taking things in and out. When door 1 is closed, if only people need to enter and exit, they can pass by by unlocking the single door or small sliding door. Furthermore, if a person attempts to move parallel to the door from the closest position inside the door when the door is closed, the person would conventionally come into contact with the support arms 21 and 22, but in the present invention, the support arms 21 and 22 Since it has a high concave surface, it does not hinder the passage of people. Since the actual length of the support arms 21 and 22 as members is longer than that of the conventional example, there is a drawback that the amount of deflection at the lower end of the door l (near the lower stile) increases, but this can be resolved by providing an appropriate locking device. . Even if the support arms 21 and 22 rotate significantly backwards when the door is opened, the door 1 will not become unable to rotate because the immediate vicinity of the garage is often open in the depth direction.

Effects of the Invention According to the present invention, the height h of the support arms 21 and 22 at the time of the gate is made to be commensurate with the size of the island, which has the advantage that it does not become an obstacle to people's passage and the construction range can be expanded. . In addition, if only people enter and exit the garage door when the garage door is closed, it may be sufficient to open and close only one door or sliding door.

Claims (1)

[Claims] The axis of rotation is a straight line that intersects a constant ground plane and a vertical plane, and two shaft fulcrums are arranged on the axis, and one end is pivotally supported by the two shaft fulcrums, and the shaft intersects with the above-mentioned axis. In a rotary elevator door consisting of two support arms that are rotatable in a plane and a decorative board installed between the open ends of the two support arms, the shape of the support arms when the door is closed is shown from below. When viewed from the outside, it is concave and the maximum height of the concave surface is a height commensurate with the height of a person, and when the door is closed as seen from the outside of the frontage, the two support arms mentioned above are connected to the upper stile and the ground surface at a height commensurate with the height of a person. The main surface of the decorative board is connected between the middle stile and the lower stile by suspending a central part shorter than the upper stile from a part of the upper stile with a hanging stile. A revolving lift door characterized by the following:
