Abstract

PURPOSE:To prevent danger and simplify the structure in the vicinity of pillars by housing a third free-moving link rod in each of both pillars, carrying out power transmission to the outside of both pillars therefrom via pivotal support points, and bringing the third free-moving link rods out of sight. CONSTITUTION:Each lower portion of pillars 31, 32 for supporting rotatably supporting points 41, 42 on the ground surface is formed into a pivot shaft structure, being made bendable in a plane parallel to each side boundary face. Each pillar is swingable by means of the rotation between the depression/ elevation angles of one free-moving link rod R' provided close to each pillar 31, 32 out of two free-moving ink rods R installed in series between pivotal support points z', z'' provided on a structure in a body with the ground surface and pivotal support points z', z'' on the upper portion of each pivotal shaft Y of the pillars 31, 32. An operating piece (r) which is in a body or cooperates with one free-moving link rod is introduced by a pivotal support point on the upper portion of the pivotal shaft in the pillar to be directly/indirectly engaged with a third free-moving link rod R'' in the pillar.

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 technology of the revolving lift door is special, in which a pivot structure is installed at the bottom of the column, and the column falls inward during the door opening/closing operation, so that the lower edge of the door follows a trajectory that does not protrude toward the road. Although disclosed in Japanese Patent Publication No. 63-103190, the floating link that is suspended from the support arm and transmits the rotation of the support arm is disposed close to the outside of the support column, which is an eyesore.

[Problem to be solved by the invention]

The technical problem of the present invention is to reduce the number of floating links disposed near the pillars of the prior art disclosed in the cited publication ζ;
The purpose is to improve the appearance and reduce the risk of serious damage by improving the structure of the parts around the pillar.

[Means and Embodiments for Solving the Problems] The structure of an embodiment of the direct lift rotary lift door according to the present invention will be described with reference to a drawing. One end of the support arms 21 and 22 is attached in the direction of It is supported by pivot points 41 and 42 respectively, and when the above lit is lowered and the main surface of the door is vertical, it becomes the closing limit, and when the above l11 is raised and the main surface of the door is horizontal, it becomes the closing limit. In the rotary elevator door configured as described above, the lower parts of the pillars 31 and 32 that support the pivot points 41 and 42 on the ground surface have a pivot Y structure, so that the pillars 31 and 32 are parallel to the side burial ground. The pillar 31 is made to be bendable within the plane, and
32 is a pivot point Z' arranged on a structure that is integrated with the ground surface, and a pivot point Z l of the pillars 31 and 32 located above the pivot axis Y.
Among the two floating connecting rods R-R' in series suspended between the two floating connecting rods R-R', one floating connecting rod R' suspended near the above-mentioned pillars 31 and 32 rotates to reach the elevation angle and depression angle. On the other hand, an actuating piece that rotates integrally with or co-moves with the first floating link rod R' is installed in the pillars 31 and 32 above the pivot Y of the pillars 31 and 32. Position pivot point Zl+
and a member U that moves up and down in conjunction with the pivot points 41 and 42 as the operating piece r and the rsl are opened and closed.
In between, the third floating link R within the pillars 31 and 32.
``'' is indirectly suspended. In addition, the rotation stroke of the support arms 21 and 220 is approximately 90"
Although a stopper for limiting the range of 1 and a biasing member for reducing the gravity of the rotating portion are separately provided, they are not shown for the sake of clarity.

[Effect]

Since the present invention has the above configuration, when the door is closed, the rs
l is vertical and support arms 21 and 22 are horizontal), pivot point 41
- The member U that moves up and down in conjunction with 42 is at its lowest position, and the columns 31 and 32 are approximately vertical. From this state II 1 ltmill, the shaft fulcrum 41.
42, the member U that moves up and down begins to rise.
893, Japanese Patent Application Laid-open No. 62-276191, etc.), when the prisoner reaches the prisoner limit, the door 1 is horizontal (the support arms 21 and 22 are vertical), and the member that moves downward in conjunction with the pivot supports 41 and 42. U
is at the highest position, but as the member U moves up and down, the third floating link rod RI 1 also moves up and down within the columns 31 and 32, so that the actuating piece r moves up and down within the columns 31 and 32. It is forced to rotate about the pivot point z'' as the rotation axis.

In advance, the pivot point Z11 is positioned so that the rotation of the operating piece r (subordinate) and the first floating link R') is at an elevation angle and a depression angle across the horizontal line with respect to the vertical movement of the third floating link R++. is selected, the columns 31 and 32 are the support arms 21 and 22.
When the door rotates approximately 45 degrees, the pillars 31 and 32 become vertical again when the door reaches its limit.

That is, during the trip of rIil from leap to foot (or vice versa), the columns 31, 3.2 make a reciprocating movement of inclination towards the inside of the property. As a result, the locus of the lower edge of the door 1 protruding toward the road side is offset, so the bottom stitching of the door l is opened and closed along an approximately vertical trajectory. The relationship between the connecting rods R' may be that they are integral, or that separate members may be fitted as long as they can rotate in unison. In the above embodiment, the vertical movement of the third floating connecting rod RI 1 is used as the pivot point. 41 and 42, but the member U that moves up and down is not essential to the present invention, and the pivot points 41 and 42 are related to each other.
Even when 42 is in place relative to the ground, support 31 and
The same result can be obtained by linking with a member that rotates together with the support arms 21 and 22 via the pivot points 41 and 42 in the vicinity of the pivot points 41 and 42 in the support arms 21 and 22, respectively. Note that V' and Vll shown in the embodiment diagrams are transmissions arranged as necessary, and V' is a support arm 21 and 2.
It is involved in the vertical movement of the third floating link Rl with respect to the rotation angle of 2, and v''' is the third floating link Rl.
This is to be involved in the rotation angle of the actuating piece r relative to the vertical movement of the IH, and even without the transmission v'v' (transmission Of course, the invention can also be implemented (direct engagement).

〔Effect of the invention〕

According to the present invention, the third floating link R11 is the support column 31.3.
2, and from the third floating link R' to the struts 31 and 3.
2. Since the power transmission to the outside is carried out via the pivot point Z', the third floating link R'' is out of sight, and the structure near the pillars 31 and 32 is reduced accordingly. It can be said that it is possible to obtain a direct-lift revolving door that is clean, and the risk of serious injury is also reduced.
