のと同一に表れる。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to external gates for buildings, particularly garage doors. [Prior Art] The present applicant is special! No. 63-26252 proposed a direct lift rotating elevator door, and this application proposes improvements to this and new expansion of applications. [Problem to be Solved by the Invention] The technical problem of the present invention is that in the first cited invention, the movement of the support arm, which is referred to as a link in the present application, determines the position of the link by positioning both ends of the link. In addition, the position of the connecting rod was also constrained at the central position of the connecting rod (the position of the third pivot shaft in book a and the cited example), but the restriction of the connecting rod by that central position was excluded. We suggest that there are some embodiments that do this. It also provides the benefit of increasing the degree of freedom in choosing the position of the fourth pivot axis in the present application. [! Means and embodiments for solving lR] To describe an embodiment of the direct lift rotary elevator door according to the present invention with reference to a drawing, there is a main surface of the door 1 near the second side edge of s1. Support arms 21a, 22a and connecting rods 2lb, 22 in the intersecting direction
One end of each of the support arms 21a and 21b is pivotally connected to each other by respective pivot axes Xa-Xb perpendicular to the side mound surface, and the support arms 21a and
The vicinity of the other end of the arm 22a is pivotally supported at a fixed position on the ground by a third pivot axis Xa parallel to the pivot axis Xa (Xb), and the rotating part K of the support arm 21a, etc. A biasing member F that counteracts the gravitational moment of the rotating part K is loaded between the ground surface and the integral structure, and when the above Is1 is in the vertical state, u
sya to the horizontal door opening limit, the connecting rods 2lb and 22b move in and out in the direction intersecting the main surface of the door in association with the rotation of the support arms 21a and 22a about the third pivot axis Xc. In a direct-lift rotary lift door that is operated so that the locus of rotation of the lower a la on the door with respect to the third pivot axis Xc is approximately vertical, the third pivot axis Xc A fourth pivot shaft parallel to and at a fixed distance from the third pivot axis Rotating wheels R of pendulum levers 71 and 72 whose rotation axis is axis Xd
The connecting rod 2lb is transmitted so that the free ends P of the pendulum levers 71 and 72 have the same relative position with respect to the support arms 21a and 22a at the closed 5w4 and open s limits. - The structure is characterized in that the other end of the pendulum lever 22b and the free end P of the pendulum levers 71 and 72 are pivotally engaged. Note that 31 and 32 are columns that support the third pivot shaft Xc at a fixed position relative to the ground surface (the pivot points of the support arms 21a and 22a and the third pivot shaft Xc are fixed at a fixed position when viewed from the top view). Therefore, the third pivot axis Xc moves up and down with the opening and closing of s1.
Even if it is placed on 1.32, its support 31.
Reference numeral 32 is still a support that supports the third pivot shaft, that is, the above-mentioned pivot point at a fixed position with respect to the ground surface. ), and a stopper is separately provided to limit the rotation stroke of the rotating portion K with respect to the third pivot axis Xc to approximately 90', but it is not shown for the sake of simplicity. Further, the second digit 2.l used in this specification 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.

増すことができる。転ｍＱからの動力伝達機構は公知の
伝動機構によってよい。Since the present invention has the above configuration, at the closing limit, the support arms 21a and 22a are at the lowest position (water il1 in the embodiment diagram), and the fourth pivot shaft Xd is at the third pivot shaft. Directly below Xc, the pendulum levers 71 and 72 are at the most counterclockwise rotation position in the illustrated side view (FIG. 3). At this time, the connecting rods 2lb and 22b connecting the free ends P of the pendulum levers 71 and 72 and Is1 have the main surfaces of fil vertical. From this state, when s1 rotates in the direction of opening the door, the rolling wheel Q
begins to rotate, and the pendulum levers 71 and 72 continue to rotate clockwise at three times the speed as shown. For this reason, the pendulum lever 71
The connecting rods 2lb and 22b engaged with the free end P of 72 will be drawn inward to the property, and the lower edge work a of the door l will rise vertically without changing the position of s1 on the original plan view. I'll go. In other words, the lower m 1 a of s1 does not protrude onto the road side and obstruct traffic. When reaching the opening limit, the pendulum levers 71 and 72 rotate in the most clockwise direction, but the position of the free end P as seen from the support arms 21a and 22a remains the same in both the closed mva and open S limits. It is set to the position. Therefore, the main surface of the door 1 is maintained horizontally at the opening limit. In other words, pendulum lever 7
In the first half of the 270@ rotation of l.72, the continuous rod is 2lb.
22b is drawn into the interior of the property, and approximately in the latter half is pushed back to the outside of the main surface of the door. The speed increase ratio is not limited to 3 times, but can be up to 4 times, and the higher the speed increase ratio, the higher the speed increase ratio is.
The amount of movement of lb and 22b increases (meaning that the distance between the pivot axes xa and Xb can be increased, which ultimately leads to a reduction in the internal stress of the connecting rods 2lb and 22b.) Fourth pivot axis Xd is not limited to being directly below the third pivot axis XC. By appropriately selecting the lengths of the connecting rods 2lb and 22b at the closing limit and the relative positions with respect to the support arms 21a and 22a, it is possible to select an infinite number of positions for the fourth pivot shaft Xd. Therefore, the degree of freedom in design can be increased accordingly. The power transmission mechanism from the rotation mQ may be a known transmission mechanism.

る。[11g to be Solved by the Invention] The technical problem of the present invention is the claim of the shaft-lifting rotary lift door proposed by the present applicant in Japanese Patent Application No. 1983-1.40784 (hereinafter referred to as the "first invention"). The present invention provides a technique for applying the invention described in 1. [Means for Solving the Problems and One Embodiment] The structure of one embodiment of the direct lift rotary elevator door according to the present invention will be described with reference to a drawing. The support columns 31 and 32 supported by the upper member 31a●
32a, the lower member 3lb and 32b are divided into two, and the upper member 3
1a and 32a are provided with the third pivot shaft Xc and fourth pivot shaft Xd, and the upper members 31a and 32a and the lower members 3lb and 32b are slidable relative to each other in the longitudinal direction. As the rotating wing R, which is fitted so as to be repelled by the biasing member F and rotates together with the pendulum levers 71 and 72, rotates at an increased speed due to the rotation of the wheel Q, the upper members 31a and 31a.
32a connects one end to the ground surface and the structure at the other end so that the lower members 3lb and 32b increase (decrease) the amount of fitting of each other against the biasing member F (by being biased). The structure is characterized in that the strip T engaged with the rotary wheel R is stretched between it and the rotating wheel R. [Function] Since the present invention has the above structure, in the prior invention, the shaft lifting distance + 1 (the ground height of the rotating shaft of the rotating elevator door is not fixed during door opening/closing, and The rotating elevator door is designed to rise when the door is closed, and to lower when the door is closed, making it possible to store cars with a higher vehicle height than normal even in narrow garage spaces.
In order to increase the lifting distance of the axis of rotation of the door as the door opens and closes, it may be possible to apply a speed change mechanism (see Japanese Patent Application Laid-Open No. 160394/1983). It is usually sufficient for the speed change mechanism to be several times as large, and this happens to coincide with the speed change ratio of the rotating wheel R to the rolling wheel Q required in the invention as claimed in claim 1. Therefore, as shown in FIG. 5, the shaft of the rotary wheel R, which is disposed mainly for the purpose of increasing the vertical movement distance of the shaft, is extended to the outside of the upper members 31a and 32a,
If the pendulum levers 71 and 72 are fixed to this so that they rotate together, a direct-elevating type (rotating elevating S in which the rotation trace of the lower Jll 1 a is approximately vertical) is obtained. be able to. Furthermore, the strip T has the same construction whether it is engaged by a chain and sprocket or a rack and binion. [Effects of the Invention] According to the present invention, by simply extending the rotating shaft of the transmission mechanism attached to increase the shaft lifting distance, it can be used as the rotating wheel R of the pendulum levers 71 and 72, and the structure is improved. It is possible to obtain a simple direct-rise type axis-lift rotating lift door. Furthermore, since a speed change transmission mechanism is an essential requirement in the present invention, it can be said that the present invention is also suitable for opening and closing heavy gates.
以下、請求項３記載の発明について述べる。The invention according to claim 3 will be described below.
本発明の技術的課題は、請求項工記載の発明において、
扉１の開閉に伴う扉１下縁の軌跡がかなり鉛直には近い

。The technical problem of the present invention is to solve the following problems in the claimed invention:
Although the trajectory of the lower edge of door 1 as door 1 opens and closes is quite close to vertical, it is unavoidable that it meanderes a few centimeters.
We will propose a concrete structure to make it even closer to vertical.
