Description

【発明の詳細な説明】 本発明は、伸縮式門扉に関する。[Detailed description of the invention] The present invention relates to a telescoping gate.

この種の伸縮式門扉は通常、一端側を固定部に
連結して開口部の横巾方向に伸縮自在に構成した
扉本体の下辺部に、この扉本体の伸縮開閉移動を
円滑化するため、それの伸縮方向に適宜間隔を隔
てて複数個の接地支持輪を付設してある。 This type of telescoping gate usually has one end connected to a fixed part and a lower part of the door body configured to be expandable and retractable in the width direction of the opening, in order to facilitate the opening and closing movement of the door body. A plurality of ground support wheels are attached at appropriate intervals in the direction of expansion and contraction.

面でも難渋するといつた不都合を招来していた。 However, conventional telescoping gates of this type are designed to be constructed on flat land, and because the positions of the plurality of ground support wheels relative to the lower side of the door body are determined in the vertical direction, they cannot be installed on hilly areas. Conventional retractable gates are installed on houses built on slopes such as
If the construction is carried out with the ground support ring in contact with the slope, the door body and the fixing parts such as the pillars that fix it will be tilted with respect to the vertical direction, which will not only make the appearance unsightly. However, the construction was difficult and caused many inconveniences.

ることを特徴とする。 The telescoping gate according to the present invention was developed with the aim of eliminating such inconveniences, and has one end connected to a fixed part so as to be extendable and retractable in the width direction of the opening. It is characterized in that a plurality of ground support wheels are attached to the ground support wheels at appropriate intervals in the direction of expansion and contraction so as to be movable up and down, and a spring is provided for biasing each of these ground support wheels to move downward.

として確保する状態で施工できるに至つた。 In other words, each ground support ring that can move up and down with respect to the door body is urged to move downward by the spring, so even if the door body and its fixed part are installed on a slope in a vertical position, each The ground support ring will always be in contact with the slope regardless of the amount of expansion and contraction of the door body, and based on its rolling motion, the door body can be smoothly extended and opened/closed, and its ground reaction force will cause the door to The main body can be supported stably. In other words, it is possible to construct the door body and its fixing part in a vertical position on a slope, while allowing each ground support ring to exert its intended effect on a slope, which improves the appearance and construction. This enabled construction to be carried out in a manner that ensured that both properties were good.

This door body 1 is configured to be expandable and contractible in the width direction of the opening A, and a plurality of ground support wheels 2 are provided at appropriate intervals in the expansion and contraction direction on the lower side of the door body 1, as shown in FIG. Attached so that it can be moved up and down,
In addition, springs 3 are provided to urge the ground support wheels 2 to move downward. More specifically,
A rod-shaped member 2a standing upright from the support ring 2 is fitted into a suitable one of the plurality of vertical members 1a constituting the door body 1 so as to be vertically slidable, and the vertical member 1a...
A spring 3 is interposed between the fixing ring 1b on the side and the fixing ring 2b on the rod-like member 2a side so as to be fitted around the rod-like member 2a.

The closer to the end of the telescopic movement (free end) of the door body 1, the larger the amount of lateral movement, and therefore the larger the amount of movement in the vertical direction. In order to ensure sufficient supporting force even in its maximum extension state, a plurality of springs 3 are used.
. . ., the closer to the telescopic movement end (the free end side), the larger the biasing force is.

金具である。 Furthermore, when the door body 1 is contracted to the minimum, all the springs 3... are contracted, and the total reaction force becomes considerably large, but regardless of this, the distance between the door body 1 and the fixing part 4 on the mounting side is In order to prevent the door from twisting, the door body 1 is connected to the fixed part 4 so that it can move relative to the fixed part 4 in the vertical direction, and even in the minimally contracted state, it occupies a considerable width L and is suitable for use in large vehicles such as automobiles. So as not to obstruct the passage of objects,
A door body 1 is connected to a fixed part 4 so as to be swingable around an up-down axis. That is, as shown in FIG. 3, a member 5 fitted to the fixed part 4 so as to be vertically slidable and the door body 1 are connected via a hinge 6. In addition, 7... is a locking metal fitting attached to the grounding support wheel 3....
