Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to exterior gates for buildings, particularly garage doors.

[Conventional technology]

The multiple pivot points of a rotating lift door are required to be horizontal, parallel to the frontage, and share a common axis, but for this reason, the supports that support the pivot points relative to the ground must be carefully selected for their mounting position, verticality, and installation height. There are very strict requirements. In order to solve these problems, the applicant has published Japanese Patent Application Laid-Open No. 59-203188.
However, the present invention adds new improvements to this proposal.

[Problem that the invention seeks to solve]

A simple mounting jig allows you to easily obtain the uniaxiality, water resistance, mounting position, etc. of multiple shaft supports of a rotating lift door, and also allows you to check the appropriate mounting height. The purpose of the present invention is to provide a rotating lift door.

[Means for solving problems]

The configuration of one embodiment of the rotary lift door according to the present invention will be described with reference to a drawing. A straight line where a constant ground level and a vertical plane intersect is defined as the axis X of the rotary lift door, and two and one end 21a, 2 at the two axis points 41, 42.
2a is pivotally supported and is rotatable in a plane intersecting the axis It consists of a door 1 installed across the support arms 21 and 22, and two supports 31 and 32 that support the two shaft supports 41 and 42 on the ground surface. In the rotary lift door, the two pillars 31 and 32 are removable at a fixed position with respect to the door] at a close distance gf, and at least one of the pillars 31 (32) is attached separately from the door l. The support arm 21 (22) is removably fixed.
The structure is characterized in that the open end 211) (22b) of ) serves as an index indicating the position of the door 1 when the door is closed after completion of construction. Note that 71 and 72 are connecting pieces between the door 1 and the support arms 21 and 22, and the support arms 21 and 22 are connected to each other.
The rotation stroke of 22 is approximately 90° between the horizontal direction and the vertical direction.
A stopper that limits the range, ii, support arm 21
A balancer that reduces the gravitational moment of a rotating part, such as a balancer, is not shown for the sake of clarity. Furthermore, the second digit 2.l of the code number 7 used throughout this specification indicates the left and right sides of the support arm system, although some are not shown, they appear the same as those of the pond system.

[Effect]

Since the present invention has the above configuration, the llt champion first temporarily fixes the second supports 31 and 32 in position using the back surface of rRl. The fixed position means that the two pillars are parallel, that they are at the same height with respect to the door 1, and that the rotation axis (axis X) of the rotation part is common. Since the door 1 can be considered to be a substantially rigid body, the farther the supports 31 and 32 are fixed from the rRl surface by the mounting brackets, etc., the more the influence of the flexure of the brackets and other intervening objects increases.
- The positional relationship of 32 becomes inaccurate, which is not desirable.

Next, the lower parts of the pillars 31 and 32 are placed into foundation holes that have been pre-drilled in the ground. At this time, pillars 31 and 32
The planting height of the support arms 21 and 22 should be determined based on the roughness and calculated tension. However, since the support arms 21 and 22 can be temporarily installed without being hindered by the temporary fixing of the door 1, the open ends 21b (22b) of the temporarily installed support arms 21 and 22 will be The position for temporary installation can be determined in advance to show the lower stile when the door is closed. That is, this temporarily attached support arm 21
- The open ends 21b◆22b of 22 directly indicate the storage position of 81 (especially regarding the height). Therefore, even on sloping earth floors, there is no need for a water system or tensioning, and the support posts 31
・It is possible to instantly know the planting position and planting height relative to the ground surface of 32, which has the advantage of simplifying construction.

In addition, the 1-size handle jig does not require a separately manufactured one, and the door l and support arms 21 and 22 are configured so that they can be used as a jig as they are, so there is no cost burden in terms of materials. Open ends 211) and 22 of support arms 21 and 22
b has meaning only as an indicator when used as a jig, so if the position is excessive or insufficient,
Simply use a piece of paper as a patch plate and mark the appropriate position as an index on the piece of paper at the spot 1\i.

〔Effect of the invention〕

According to the present invention, the horizontal and parallel to the frontage of the upper stile of the door 1 temporarily fixed during construction of the rotating lift door, the verticality of the vertical stile, and the open ends 211 of the temporarily attached support arms 21 and 22]・2
2b, the installation position and posture of the properly installed cleavage supports 31 and 32 can be determined, so there is an advantage that the construction is simple and inexpensive (the cost increases due to the structure of the present invention). (There are almost no elements.)
