Abstract

PURPOSE: To facilitate assembly by journaling two coaxial pairs of connecting rods on a journal point borne on each strut, and binding the free ends of each pair of connecting rods at two pivotal support points which freely move toward an away from a perpendicular as support arms are rotated for raising and lowering. CONSTITUTION: A rotating shaft 41 on two struts 31 is supported by a link mechanism consisting of two pairs of connecting rods 71a, and two arms 21 fitted with a decorative panel are secured to a shaft 41 placed on a turning axis X. An energizing member 61 resisting the gravity moments of the turning parts of a door or the like is provided inside each strut 31. The turning of the arms 21 is associated with the connecting rods 71a by gear engagement, etc., for example, and as the arms 21 are raised and rotated, a journal point 41 is raised or lowered. Thus, assembly is facilitated and the construction cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applicable to buildings, particularly external gates such as garage doors.

[Conventional technology]

The conventional rotary lift door of the axis lift type is disclosed in Japanese Patent Application No. 61-3, for example.
As in No. 12825, the strut is divided into upper and lower halves, and the divided struts are configured to be able to fit and slide each other in the longitudinal direction, and each of the divided struts is required to be a rigid body. .

[Problem that the invention seeks to solve]

The technical problem of the present invention is to obtain an axial hip-rotating lift ys <rotating lift door for high-roof vehicles) without dividing the support column, and an independent lifting mechanism is different from that of a conventional non-axis lift rotating lift door. It can be seen that it was attached to the pillar of
Assembly is easier than with conventional shaft-lifting and rotating doors, and there is no need for the rigidity and robustness of the cover of the shaft-lifting mechanism (corresponding to the strut of the divided upper part of conventional shaft-lifting and rotating doors). The purpose is to obtain the following advantages.

[Means and Embodiments for Solving the Problems] The structure of an embodiment of the shaft-lifting/rotating door according to the present invention will be described with reference to a drawing. An axis X, and two shaft fulcrums 41 and 42 arranged on the axis
and one end 21a, 22a of the two shaft fulcrums 41, 42.
two support arms 21 and 22 which are pivotally supported and are rotatable within a plane intersecting the axis X, and the two support arms 21
・A decorative board (rli) l is installed between the open ends of the support arms 21 and 22 in a direction intersecting with the two support arms 21 and 22, and two support arms 41 and 42 that support the two support arms 41 and 42 respectively on the ground surface. pillars 31 and 32, the door 11, and the support arm 21.
In a rotary lift door consisting of urging members 61 and 62 that provide a moment in the anti-gravitational direction that counteracts the gravitational moment shown by the rotating part K, the two pivot points 41 and 42 are attached coaxially to the axis X. a series of at least two pairs of rods 71 each;
a・71a,? 2a and 72a, and the free ends 71a' and 71a of the respective pairs of connecting rods 71a and 71a are connected to the pivot points 41 and 4 in a plane intersecting the axis X.
Horizontal distances d that are approximately symmetrical to each other with respect to the perpendicular line below 2
The second pivot point Q is movable near and far in relation to the vertical rotation of the support arm 21φ22 while maintaining the -d relationship.
The configuration is characterized in that each is constrained by -Q.

Note that a stopper is separately provided to limit the rotation stroke of the support arms 21 and 22 over a range of 90 degrees from the substantially horizontal direction to the substantially vertical direction, but is not shown for the sake of clarity. Also, the second digit of the code number used in this specification is 2.
・1 indicates the left and right sides of the support arm system, and although some are not shown, they appear the same as those of other systems.

[Effect]

Since the present invention has the above configuration, as the support arms 2 and 22 move up and down, the pair of connecting rods 71a, 71a, 7
Since a mechanism is provided separately to increase and decrease the horizontal paths 1aid-d such as the free ends 71a' and 71a' of the free ends 71a' and 71a' of the pairs of connecting rods 71a, 72&...
・Can be approximately horizontal or vertical. Perfect axis
We can expect an increase in the number of people. In this case, the pair of links 71
It is natural that the axis
- The support arms 21 and 22 are connected so as to adopt the upper limit position by directly or indirectly receiving the transmission force from 72a. The structure in which the distance II (2d) between the pivot points Q-Q is expanded or reduced is, for example, the structure shown in FIG. The pair of support rods 71b and 71b are connected to the rods 71a and 71a.
The other end is pivotally connected to the support 31, and they are arranged so as to intersect with each other so as to form an X shape when viewed from the side. - The rotation surfaces of the support rods 71b and 71b, which are the ends of the many ends (pivot points) Q and Q1t9, are within the plane that appears in the side view, and the bases (other ends! 1) of the support rods 71b and 71b are on the side surface of the upper end of the support column They are pivoted near the left and right ends in the figure. Support rod 71b near the pivot points of support rods 71b and 71b
・By providing driving wheels 81, 81 integrally with 71b, and engaging the floating rod 91 with the outer peripheral ends of these driving wheels, if the rotation angle of the driving wheels 81, 81 is within a small range, the driving wheels 81, 81,
Both working wheels 81 can be considered to be rotating synchronously.
- 81 can be rotated in opposite directions. Therefore, the pivot point Q-Q is restrained so as to have a symmetrical movement distance d-d in the direction intersecting the axis X with respect to the axis of the support column 31 as seen in the plan view. Since the pivot point 41 is uniquely given to the pivot point Q-Q, which is given uniquely, the pivot point 41 moves up and down with respect to the axis of the column 31 as the connecting rod 71a rotates. Become. In this case, the vertical distance of the shaft fulcrum 41 is determined by adding the sine of the rotation angle of the support rod 71b to the length of the continuous rod 71a. Now, if the rotation of the support arm 21 and the rotation of the - connecting rod 71a are directly or indirectly (meaning through gear engagement, etc.) associated via the shaft fulcrum 41, the support arm 21 As the door 1 moves up and down, that is, the door 1 opens and closes, the pivot point 41 (42) moves up and down.

〔Effect of the invention〕

According to the present invention, the lifting mechanism of the shaft supports 41 and 42 is placed directly on the pillars 31 and 32, so the pillars are divided into upper and lower parts like the conventional shaft-lifting and rotating elevator doors, and each It eliminates the need for fitting large and small diameters, which is advantageous in terms of materials and assembly process. It is sufficient to cover the area near the shaft support with a sheet-like material for the sole purpose of waterproofing.
