Abstract

PURPOSE:To obtain a compact rotary elevating door by a method in which the support arm of a door is supported by the shaft supporting point of a strut, and a projected shaft set on the intermediate of the arm is slidably fitted into the long hole of a pendulum lever attached to the other pivotal shaft of the strut. CONSTITUTION:One end of a support arm 22 is attached to near the side of a door 1, and the other end of the arm 22 is pivotally supported by the shaft support point 42 of a strut 32. The projected shaft P set on the intermediate of the arm 22 is slidably fitted into the long hole V of a pendulum lever L pivotally attached to the third pivotal shaft T. A travelling connection lever R is coupled between the pivotal shafts Z and U of the door 1. When the door 1 is opened, the shaft P is turned around the shaft X as the arm 22 rotationally rises, the lever L is turned around the shaft T, and the door 1 is raised vertically through the lever R coupled with the shaft U. A compact rotary elevating door with the lever L of a swing angle of 90 deg. can thus be obtained.

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]

When a revolving lift door is opened and closed, the lower edge of the door does not have a trajectory that protrudes toward the road, and the door that opens and closes along a nearly vertical trajectory as far as the lower edge is is an effective use of land. JP-A-61-106882, JP-A-61-12
No. 6287, a patent application submitted by Junto Motode on June 27, 1988, etc. In both cases, a pendulum lever, which is a type of link mechanism, rotates approximately 180 degrees to change the angle at which the door is attached to the support arm (see No. 11!I). ).

[Problem to be Solved by the Invention] A technical problem of the present invention is to propose a direct-lift rotary elevator door with a compact structure in which the swing angle of the pendulum lever is 90''.

[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.In the vicinity of the 20 side edge of 11t1, there is a main surface of the door l and One end of the support arms 21 and 22 is attached in the intersecting direction, and the ends of the support arms 21 and 22 are connected to the two ends arranged on one axis X perpendicular to the side boundary surface. Axial fulcrum 41
42, respectively, so that when the door Ill is lowered and the main surface of the door is vertical, it is at the leapway limit, and when the door I is raised and the main surface of the door is horizontal, it is at the leapway limit. In the rotary elevator door, the above-mentioned I11 and the above-mentioned one end of the support arms 21 and 22 are attached by a pivot engagement by a first pivot Y parallel to the above-mentioned axis X, and the above-mentioned support arm 21・22
A protruding shaft P is disposed parallel to the axis outside the property and at an elevation angle of approximately 46
The length of the pendulum lever L, which is arranged on the supports 31 and 32 that support the shaft supports 41 and 42 on the ground surface in the ° direction, and whose one end is pivoted to a third pivot T parallel to the axis X. The pendulum lever L is slidably fitted into the hole V, and a fourth pivot U is disposed on the pendulum lever L substantially coaxially with the protruding shaft P of the support arms 21 and 22 at the closing limit of Ill. The axis U and the axis X at a position different from the first axis Y on the side edge of the bolt
The structure is characterized in that a floating link R, whose both ends are pivotally engaged, is engaged between the second pivot shaft Z and the second pivot Z, which is disposed parallel to the second pivot shaft Z. Note that a stopper that limits the rotational stroke of the door l to a range of 90° and a biasing member for offsetting the gravitational moment of the prisoner l are not shown for the sake of clarity. Further, the second digit 2.1 of the number 7 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.

[Effect]

Since the present invention has the above structure, when the prisoner 1 is at the door closing limit, the pendulum lever L (therefore, the elongated hole V) hangs vertically downward. If you open Ill from this state,
Since the protruding shafts P disposed on the support arms 21 and 22 rotate together with the support arms 21 and 22 around the axis X, it is necessary to forcibly rotate the pendulum lever L around the third pivot T. (At this time, the protruding shaft P slides in contact with the elongated hole V of the first pendulum lever in the direction of the third pivot T.) On the other hand, the pendulum lever L is provided with a fourth pivot U.
and the second axis Z of sl are engaged by a floating link R (the length of the floating link R is predetermined so that i1 is vertical at the beak closed limit). , prisoner 1 moves support arm 2 as support arms 21 and 22 rotate upward.
The mounting angle with respect to 1.22 will be varied in the acute angle direction.

This acute angle becomes the minimum when the support arm rises approximately 45 degrees, and then gradually returns to the 90" direction and reaches the gap limit. If the axis U of the pendulum does not match perfectly, yfil at the leap gate limit will not be completely horizontal but will be slightly inclined.) Depending on the length of the pendulum lever L, the installation angle of $1 will be an acute angle. Although the degree will vary, if you select it appropriately, you can determine the length of the pendulum lever L under the condition that the lower edge of itl rises and falls almost vertically and the door 1 opens and closes.The long hole ■ is a long groove. Also, since the pendulum lever L is horizontal when the elevator door is at its limit, the rotation angle of the pendulum lever L from when the door is closed is 90 degrees.

〔Effect of the invention〕

According to the present invention, the rotation angle of the pendulum lever L is 90 degrees, and the shorter the length of the pendulum lever L, the greater the displacement of the floating link R. It is advantageous to have a compact construction (assuming that the pendulum lever L is the same size, a conventional 180' displacement of the pendulum lever L means that twice as much space is required.

).

The invention according to claim 2.3 will be described below, but the [industrial application field] and [prior art] are the same as those described above.

Problem U that CQ HA attempts to solve] In the invention as claimed in claim 1, if the fitting portion between the elongated hole V of the pendulum lever L and the protruding shaft P can be housed within the pillars 31 and 32, the appearance can be improved accordingly. l! It can be made clean. Further, it provides a structure that prevents rainwater from penetrating into the pillars from the grooves and the like.

[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 the drawings. The attached member is attached to the support column 31 via the pivot points 41 and 42.
・On the other hand, the pendulum lever L is branched into a pillar pendulum lever La and an intra-branch pendulum lever Lb via the third pivot T, and the intra-branch pendulum lever Lb has an elongated hole or The structure is characterized in that a long groove is provided, and a fourth pivot U is provided in the columnar pendulum lever La.

[Action and effect]

Since the present invention has the above configuration, the support arm 21
・A mechanism that transmits the rM door rotation of 22 to the pendulum lever L, that is, the elongated hole V provided in the pendulum lever L and the support arm 2
The mechanism portions that fit with the protruding shafts P disposed at 1 and 22 are housed within the supports 31 and 32, and the appearance can be made simpler accordingly. A method of introducing a part of the support arms 21 and 22 into the pillars 31 and 32 can also be obtained by suitably trimming the solid support arms 21 and 22, but it is also possible to finally introduce parts of the support arms 21 and 22 by suitably combining separate members. Even if they are fixed together, the support arms 21 and 22 are still one piece.The pendulum lever outside the column La and the pendulum lever inside the branch Lb are connected via a third pivot T, and the support arms 21 and 22 are connected to each other via a third axis T, and the support arms 21 and 22 are connected to each other via a third axis T. As can be seen from the six or more configurations that are U-shaped when viewed from the direction, the only points where the transmission system and the pillars 31 and 32 intersect are the pivot points 41 and 42 and the third pivot T, so rainwater It can be said that the watertightness of the support columns 31 and 32 against the structure is good, and although not shown, it is possible to ensure the safety of the $1 weight reduction biasing member and the like from rainwater. Further, regarding the operation, there is no essential difference from the invention described in claim 1.

The invention according to claim 3 will be described below.

[Problem to be solved by the invention]

A technical problem of the present invention relates to a method of transmission engaging the intra-branch pendulum lever Lb and the support arms 21 and 22 in the invention according to claim 1 or 2, and applying another transmission mechanism with less friction than the link mechanism. That's true.

[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 the drawings. Instead of the fitting engagement between the and the protruding shafts P disposed on the support arms 21 and 22, the gears of the same diameter disposed on the pendulum lever L and the support arm 2122 engage with each other,
The structure is characterized in that the pendulum lever L and the support arms 21 and 22 are transmission-engaged.

[Action and effect]

Since the present invention has the above configuration, the support arm 21
・When 22 starts to rotate upward from the closing limit (centered on axis (The pendulum lever Lb in the column can be formed as a gear as it is, and since the rotation angle of the gear is 90@, a quadrant gear is sufficient.)The subsequent operation has already been described in this specification. This is the same as described above.

Although it cannot be said that the operation is completely the same in terms of rotation transmission speed,
This is a minor difference, and there is no change in the fact that the anchor ITa moves up and down approximately vertically. According to the present invention, since the transmission engagement between the pendulum lever L and the support arms 21 and 22 is gear transmission, smoother operation can be expected with fewer sliding friction parts.
