Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is applied to external gates for buildings, particularly garage doors.

[Conventional technology]

The present invention is an improvement proposal of Japanese Patent Application No. 61-130951 (title of invention: "Axis-lifting/lowering rotary lifting door"). The rotating lift door according to the cited application is of a type in which the pivot axis of the decorative panel (door) moves up and down with respect to the ground surface, and the support arm of the door interposed between the pivot axis and the door is , extends from the above-mentioned shaft in the direction of the door, and its extending end is restrained at a substantially constant height above the ground by being restrained by a continuous rod between the ground and the integral object. Since the connecting rod is exposed to the outside of the pillar, the drawback that the movement of the connecting rod can be seen as the shield is raised, lowered, and opened/closed has been eliminated.

[Problem that the invention seeks to solve]

The technical problem of the present invention is to improve the above-mentioned drawbacks of the prior art,
To provide a rotating elevator door having a structure in which the operation of a continuous lever is not visible at all or the operation of a continuous lever is substantially hidden.

[Means and Embodiments for Solving Problems] The structure of an embodiment of the rotating lift door according to the present invention will be described with reference to the drawings.
The straight line where the constant ground plane and the vertical plane intersect is the axis of rotation・Two support arms 21 and 22 which are pivotally supported by 22a and are rotatable in a plane intersecting the axis X; and the two support arms 21 and 22.
A decorative plate (1) is installed between the free ends in a direction intersecting the two support arms 21 and 22. 3
1 and 32, the rotation stroke of the biasing members 6I and 62 that provide a moment in the anti-gravity direction that counteracts the gravitational moment exhibited by the rotating parts such as m1 and the support arm 21, and the second support arm is approximately 90 degrees. In the rotary lift door consisting of stoppers 51 and 52 that regulate the angle of
and the upper member 3 connected to the above-mentioned shaft fulcrums 41 and 42, respectively.
1a, 32a, and lower members 31b, 32 installed across the ground surface.
The second upper members 31a and 32a slide directly against the second lower members 31b and 32b, respectively, while being biased vertically upward by the biasing member 61#62. while the one end 21a of the second support arm
・22a roughly extends inward of the property when the door is closed, and the extending ends 21a' and 22a' are connected to the upper member 3.
The structure is characterized in that the distance from a fixed point P, which is integral with the ground surface, is always restrained to a substantially constant distance by floating linking rods 71 and 72 housed in 1a and 32a. Note that the upper member 31a
- There is no substantial difference in the sliding movement between 32a and the lower members 31b and 32b even if the sliding movement is indirect sliding via another member. It is also possible to use cables instead of the floating linkages 71 and 72 for the same construction. Also, the second digit of the code number used in this specification is 2.1.
shows the left and right sides of the support arm system, some of which are not shown but appear identical to those of other systems.

[Effect]

Since the present invention has the above structure, the weight of the rotating parts such as 11 is offset by the urging force of the urging members 61 and 62, and therefore the operating force for opening and closing 111 is extremely light. As the door 1 opens and closes, the pivot points 41 and 42, and therefore the upper member 31
A and 32a are also designed to move up and down. These elongated ends 21a' and 22a' are restrained by floating link rods 71 and 72 and have a substantially constant ground level (strictly speaking, a horizontal arc).
By the way, the operation of the floating linking rods 71, 72 cannot be recognized from the outside because the floating linking rods 71, 72 are located inside the upper members 31a, 32a. Naturally, if the upper member is partially open, the floating linking rods 71 and 72 can be seen visually, but the floating linking rods 71 and 72 can be seen from the side view.
Anything that even partially conceals the operation of 72 can be said to have expected and achieved the effect of concealment. Furthermore, if the free ends of the connecting rods 71 and 72 are restrained by guide grooves that are disposed integrally with the ground surface and are approximately equal to the trajectory of the free ends, the connecting rods 71 and 72
・Although 72 is no longer necessary, it is a substantially equivalent means.1 The present invention is applicable not only to independently arranged rotating lift doors, but also to pillars of garages when a covered garage and rotating lift door are integrated. It is. In this case, the members that are integrated with the pillars planted on the ground surface become the lower members 31b and 32b, and the upper members 31a and 32
A may be inserted into the pillar as a cylinder with both ends open. Further, as shown in FIG. 5, the connecting rods 71 and 72 can be arranged substantially horizontally. The operation and effect are essentially the same as in the above case.

〔Effect of the invention〕

According to the present invention, all or part of the operating range of the floating link or cables 71 and 72 is made invisible through the upper members 31a and 32a, which improves the appearance and prevents major damage. It is also beneficial from the standpoint of safety.

Claims (1)

[Claims] The axis of rotation is a straight line that intersects a constant ground height plane and a vertical plane, and two fulcrums are placed on the axis, and one end of the axis is supported by the two fulcrums, and the axis intersects with the above axis. two support arms that are rotatable in a plane, a decorative plate that is disposed between the free ends of the two support arms in a direction intersecting the two support arms, and the two shafts of the two support arms. A second support that supports each fulcrum relative to the ground; a biasing member that provides a moment in the anti-gravity direction that counteracts the gravitational moment exerted by the rotating parts such as the decorative board and the support arm; and the second support arm. In a rotary lift door consisting of a stopper that restricts the rotation stroke to approximately 90 degrees, each of the two pillars is divided into two parts: an upper member connected to the shaft fulcrum, and a lower member fixed to the ground surface. The two upper members are respectively slidable directly or indirectly with respect to the two lower members while being biased vertically upward by the biasing member, while the one end of the second support arm is vertically upwardly biased by the biasing member. When the door is closed, the extension is further extended inward of the property, and the extension end is always kept at a substantially constant distance from a fixed point that is integral with the ground surface using a floating connecting rod or cable housed in the upper member. A rotating lift door characterized by being restrained by.
