JPH0376950A - Blockading device of space between adjacent roof members in opening and shutting roof - Google Patents

Abstract

PURPOSE:To make sure to blockade a space by providing air bags provided with steel plates on the tip to one end of adjacent roof members piling up the ends through a space to expand when the surface of a roof is shut and, at the same time, attracting the steel plates by electromagnets on the other end. CONSTITUTION:When the surface of a roof is shut, roof members 1 and 2 adjoining and piling up through a space H are formed. After that, unit air-bags 3a are piled up to the end edge of the lower roof 1 to fix a bellows type unit 3 having steel plates 4 on the tip. Then, air-hoses 6 branched from air pipings 5 are connected to each of the unit bags 3a. In addition, electromagnets 8 are loaded to the end edge of the upper roof 2 in correspondence with the bags 3a. When the surface of the roof is shut, if the space H is blockaded, pressure- air is simultaneously enclosed into each of the air-bags 3a to expand, and the steel plates 4 are attracted and fixed by the electromagnets 8. According to the constitution, even if the space is changeable, blockade can be made with quick, position and high proof strength.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a gap sealing device between adjacent roof members in a retractable roof.

(Prior art) Fig. 7 to Fig. 9 show a retractable roof, in which a plurality of roof members (a), (c), (d), (e), and (f) move in the direction of the arrows, and the roof surface It opens or closes the

When the roof surface is closed, a gap is created between adjacent roof members, as shown by X in FIG. This gap is large because the roof frame is highly deformed, and at the same time, it must be able to cope with fluctuations due to natural external forces such as wind, earthquakes, and snow, and large forces are also applied to it.

Conventionally, in order to close the gap, for example, one roof member (
C) on the edge of the overlapping surface with respect to the other roof member (b),
A rubber sheet (B) supported by a bent steel plate (B) is mounted so as to be brought into close contact with the other roof member (C) when the roof surface is closed. (See Figure 10) Or,
A structure in which an air bag is interposed between the overlapping surfaces of both roof members (B) and (C) is also adopted.

(Problem to be Solved by the Invention) In the former case, when the gap between adjacent roof members becomes large, the rubber sheet also becomes large, which is wasteful. Furthermore, the vertical displacement of the gap can be dealt with by increasing the elasticity of the rubber sheet, but this can only be applied to the extent of the elasticity of the rubber sheet, and cannot be used for large-sized retractable domes.

In the latter case, high internal pressure is required to maintain airtightness, and a large force is applied to the air bag due to deformation of the Mm frame. Furthermore, it takes time to take air in and out of the air bag.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to quickly and reliably reduce the gap between the overlapping parts of adjacent roofing materials in a retractable roof that is subject to large deformations and fluctuations. The object of the present invention is to provide a sealing device that can close the same gap.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a gap sealing device between adjacent roof members in a retractable roof according to the present invention is provided such that when the roof surface of the retractable roof is closed, the end portion closes the gap. An air bag with a steel plate attached to the tip surface is installed at the end of one of the adjacent roof members that overlap with each other, and an electromagnet is installed at the end of the other roof member. It is configured as follows.

In addition, so that the gaps between the roof members can be quickly sealed,
The air bladder is composed of bellows-shaped units stacked in multiple stages, and the units are arranged in a row along the edge of the overlapped portion of the roof member, and each unit is connected to an air injection pipe, respectively.

(Function) Since the present invention is configured as described above, when the roof surface of a retractable roof is closed with a roof member, the end of one roof member is When the air bag mounted on the air bag is filled with air and inflated, and the 11 magnet mounted on the other of the roof members is excited, the steel plate attached to the tip of the air bag is attracted to the electromagnet. By doing so, the air bag is fixed between the two roof members, and the gap between the overlapping portions of the two roof members is firmly sealed.

The invention according to claim 2 is characterized in that the air bags mounted on the roof member are constructed from bellows-shaped units stacked in multiple stages, and the units are arranged in rows along the edge of the overlapping part of the roof member, and each of the air bags Since the air injection pipes are connected to the air bags of the units, the units can be rapidly inflated, and the gap between the overlapping parts of the roof members can be quickly sealed.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(1) and (2) are adjacent roof members in a retractable roof, and when the roof surface is closed, the ends of both roof members (1) and (2) are between l! Polymerizes in the presence of H.

A bellows-type unit air bag (3) consisting of multiple layered unit air bags (3a) on the end face of the roof member (1) located below the overlapping part, and a steel plate (4) attached to the tip face.
an air hose (6) branching out from the air pipe (5) arranged on the roof member (1);
is connected to each unit air bag (3a).

The unit air bags (3) are arranged in a row along the edge of the roof member (1), and an interlayer film (7) is connected between adjacent unit air bags (3). (See Figures 2 and 3) On the other hand, the roof member (2) located above the overlapping part
An electromagnet (8) is attached to the end face of the unit air bag (3) at a position corresponding to the unit air bag (3).

Since the illustrated embodiment is configured as described above, when closing the gap H created at the overlapping part of both roof members (1) and (2) when the roof surface is closed, the air pipe (5) Pressurized air is filled into each air bag (3a) of the unit air bag (3) mounted on the roof member (1) via an air hose (6) to quickly inflate the unit air bag (3). and then raise it as shown by the arrows in FIGS. 1 and 2.

On the other hand, the electromagnet (8) of the roof member (2) is energized, and the steel plate (4) attached to the front end surface of the unit air bag (3) is
By suctioning and fixing the roof member (1) (
2) Close the gap H in the overlapping part.

Furthermore, when the retractable roof is opened, the electromagnet (8) is demagnetized and the air bag unit (3) is reduced in size, the air bag unit (3) also falls due to its own weight and quickly shrinks. .

Figures 5 and 6 show another embodiment of the present invention, in which an air tube (9) whose lower end is fixed to the roof member (1) is covered with a bellows-type shield 0ω, and the tips of both are covered. This shows the case where the steel plate (4) is installed, and since the air capacity is small and there is no direct contact with the outside air, safety is high.

In the figure, parts equivalent to those of the above embodiment are given the same reference numerals.

(Effects of the Invention) As described above, the present invention provides a retractable roof in which a steel plate is attached to the end surface of one of the adjacent roof members whose ends are overlapped with a gap between them. By installing an air bag and installing a 1tVA stone at the end of the other roof member, it is possible to eliminate gaps that are accompanied by large deformations and fluctuations that occur at the overlapping part of adjacent roof members when a retractable roof is closed. The electromagnet attracts the steel plate at the tip of the air bag, effectively sealing it out from the cold and against natural external forces such as wind, earthquakes, and snow.
The gap sealing portion has a high yield strength.

In addition, since an air bag is used as a gap sealing member,
Even if the gap is uneven, it can be reliably sealed.

Furthermore, according to the present invention, since the air bag is raised from below to shield the gap, the shape has a large rise against wind and water blowing in from the roof surface, so it is difficult to protect against headwinds and water. High shielding properties.

In the invention as claimed in claim 2, the air bag is constituted by a bellows-like unit in which unit air bags are layered in multiple stages, and an air injection pipe is connected to the unit air bag of each unit at the edge of the overlapping part of the roof member. By doing so, the unit air bag is quickly expanded with fat, and the gap between the overlapping parts of the roof member is quickly sealed.
