めることが困難であるという問題点があつた。 Manual swing-up doors have been known for a long time, which are equipped with a pair of straight left and right guide rails that extend horizontally in the front-rear direction (depth direction) above the inside of the opening of a structure (generally near the ceiling). (For example, see Japanese Utility Model Application Publication No. 56-45071). In general, this straight guide rail has the advantage of being easy and inexpensive to manufacture, and also simple to install. However, in swing-up doors with linear guide rails, in order to allow the door body to move smoothly, the linear guide rails on the structure side, which are provided in the front-rear direction above the inside of the opening, are used. It is necessary to configure the door so that there is some play between the front end and the hanging wheel on the door body side that travels in the front-rear direction while being guided by the guide rail. The existence of this play causes the following problems in the latter half of the process of closing the door body. In other words, when the door is configured to be opened and closed by a driving means equipped with a prime mover such as an electric motor installed parallel to the guide rail, the vertical movement of the lower end of the door body relative to the amount of horizontal movement of the upper end of the door body Since the amount of movement α in the direction has already become small, no matter how much the upper end of the door body is moved in the horizontal direction, the door body will return to the upper limit position of the play due to the force of the tension spring acting on the swinging arm. The lower end of the door body cannot be completely closed because the lower end of the door body remains lifted up, and if the door is a manual type without a drive means, the lower part of the door body must be pushed down by hand. Although the lower end of the door body does not close completely,
Since the amount of movement α of the lower end in the direction in which the door body is pushed down by hand has already become smaller in proportion to the amount of horizontal movement of the upper end, the existence of the play cannot be ignored, and the upper end of the door body There was a problem that it was difficult to close the door completely.

ことを特徴とする。 That is, the present invention has a pair of left and right linear guide rails provided almost horizontally in the front-rear direction at the inside upper part of the opening of the structure, and a suspension car that runs guided by the guide rails at the upper end of both sides. The door body is pivoted to the structure side so as to rotate around a rotation center set at a predetermined height from the bottom of the opening of the structure, and when the door is closed, the bottom In the swing-up door, the swing-up door includes a pair of left and right swing-up arms whose tips are pivoted to the lower end of the door body, and a tension spring tensioned to balance the weight of the door body. The door body is characterized in that the door body is provided with a protrusion on the side edge thereof, which continues to abut from the inside during the final section of the door closing stroke, at a height approximately midway between the left and right ends of the door body.

向の運動成分に変換される。 In the illustrated embodiment, reference numeral 1 denotes a pair of left and right linear guide rails provided in the front and back direction parallel to the ceiling at the upper part of the inside of the opening of the structure, and the hanging wheel 2 runs guided by the guide rails. Reference numeral 3 denotes a door body in the form of a single plate that is attached to an opening O of a building, and the hanging wheels 2 are provided at the upper ends of both sides of the door body. Reference numeral 4 denotes a chain device arranged parallel to the guide rail, which drives the upper end of the door body 3 in the front-rear direction. Reference numeral 6 denotes a swing-up arm for swinging up the lower end portion of the door body, and a rotation center shaft 5 provided at an intermediate portion ₆₀ of the swing-up arm is supported by the building side. One end 6 ₁ of the swing-up arm is pivoted to the lower end of the door body, and a tension spring 7 is stretched between the other end 6 ₂ and the bottom surface G of the building. 8
are protrusions protruding from both left and right ends of the upper part of the door body 3, and the side edges of the corresponding opening O on the building side from the open/closed state before the door body 3 is completely closed. sliding contact from the inside. Therefore, the upper end of the door body 3 is driven forward by the chain device 4 against the force of the tension spring 7 to close the door body, and compared to the amount of movement of the upper end of the door body in the horizontal direction. In the second half of the closing stroke when the amount of vertical movement of the lower end is reduced, the protrusion 8
slides into contact with the corresponding side edge of the building side from the inside, and thereafter the door body 3 rotates and slides around the protrusion 8, and the horizontal movement of the upper end of the door body causes the protrusion to move around the protrusion 8. It is converted into a horizontal motion component in the opposite direction of the lower end at the center.
