Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gate for external structures such as buildings, particularly garages, etc.

[Conventional technology]

An electric shaft lift/lower rotary lift door has been proposed in Japanese Patent Laid-Open No. 14977/1983, and the present invention is a revised M proposal for this. (What the invention is trying to solve!lliQ) The technical am of the present invention is to provide an electric shaft lifting/lowering rotating lift door which is suitable for application to the lifting/lowering/rotating lift barrier proposed in Japanese Patent Application Laid-open No. 62-276191 etc. provide. Note that the above-mentioned "suitable" includes the convenience of converting an existing non-motorized shaft lift/rotating lift door to an electric door. [Means and Embodiments for Solving the Problems] To describe the structure of an embodiment of the electric rotating lift door according to the present invention with reference to a drawing, there is a main surface of the door l near the second side end piece. One end of each of the support arms 2l and 22 is attached in a direction intersecting with the other end of the support arm 21 and 22, and the other end of the support arm 21 and 22 is arranged on one axis X perpendicular to the side boundary surface of the garage. When the above fit is lowered and the main surface of the door is vertical, it is closed/IJ limit, while the above door 1 is raised and the main surface of #A door is horizontal. In the rotating elevator door that is set to the opening limit when
a. It is divided into two members, lower members 3lb and 32b, and the upper members 31a and 32a are provided with the above-mentioned shaft supports 4l and 42, and are slidable in the longitudinal direction with respect to the lower members 3lb and 32b. and the upper members 31a and 32a are urged against each other by biasing members 61 and 62 in a direction further upward relative to the lower members 3lb and 32b,
On the other hand, on the outside of the side surfaces of the upper members 31a and 32a. N
A gear box G shaped into a shape is attached, and an extension part T that converts rotational output into a linear reciprocating output is hung from below the gear box G, and the lower end Ta of the extension part T is connected to the above-mentioned point. The drive source (motor M) and the control unit C that are engaged with the lower member 31b (32b) and transmitted to the gear box G are moved in a direction intersecting the main surface of the gear box G.
It is an ellipse that is characterized by being integrated with the
Note that a stopper that limits the rotation stroke of the support arms 21 and 22 to approximately 90' is not shown for the sake of clarity. Also, the second digit of the code used in this book 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. ．． [Operation] Since the present invention has the above-described structure, first consider the operation when the gear box G and motor M are not attached to the upper members 31a and 32a.At the closed S limit, the upper members 31a and 32a 32a is at the lowest position relative to the lower members 3ib and 32b. The weight of the rotating part K including s1 and the support arm 21, the weight of the upper members 31a and 32a, and the gravitational moment of sl with respect to the pivot points 41 and 42 are reduced by the biasing members 61 and 62. Therefore, door 1 can be opened and closed with a light operating force.
The situation is the same with the existing manual shaft elevating/lowering rotating elevating door, but now an integrated motor M, control S section C, and gear box G is attached to the upper members 31a and 32a (WN is simply fitted). ), when the lower end Ta of the extension part T from the gear box G is anchored integrally with the lower members 3lb and 32b or the ground surface, the extension part T is extended by the rotation of the motor M, and therefore the upper member 31a. 32a is forced to move up and down, and as a result, 581 can be automatically rotated up and down. The means for converting the rotational motion of the gear box G into linear reciprocating motion is as follows:
A known screw mechanism, rank-and-binion, or other chain means may be used. In order to avoid the risk of inadvertent external force being applied while the door 1 is being raised and lowered, the transmission mechanism between the extension part T and the gear box G should be a reversible mechanism such as a ball screw, sliding screw, or rank-and-binion. It is sufficient to insert a friction clutch or the like in the part. To configure the gearbox GIN type, for example, a combination of spur gears may be used. In the present invention, the motor M. Control part C etc. are on pillar 3]
,・ Since it can be installed on the front, rear, or upper part of (32), it does not particularly limit the storage space of the car. Since the gearbox G is also made thin, it will not be a problem when storing the car. In addition, the oil drive source, gear box G, extension part T, etc. according to the present invention can be easily attached to an existing shaft-lifting/lowering rotary door, so demand can be expected to increase and the industrial application will be improved. Beneficial.

〔Effect of the invention〕

According to the present invention, the struts 31 and 32 are connected to the upper members 31b and 32.
The drive source, gear box G, extension part T, etc. can be attached and fixed without interfering with the storage of the vehicle in the shaft lift/lower rotating lift door of the type divided into 2 parts, making it very convenient for the user. An electric rotating lift door can be easily installed.

The invention as claimed in claim 2 will be described below, but the [industrial application field] and [prior art] are the same as those described above. [Invention tries to solve it! A technical object of the present invention is to provide a direct-lift electric rotary lift door that operates more reliably in the invention set forth in claim 1.

(Means and embodiments for solving !Iff) The structure of an embodiment of the electric rotary lift door according to the present invention will be described with reference to a drawing. The engaging portion is pivoted by a pivot Y that is parallel to the pivot are arranged in parallel, and the other ends of the connecting rods 21a and 22a are arranged on the measuring surfaces of the upper members 31a and 32a,
If the pendulum lever L is pivoted at the free end of the pendulum lever L, which rotates at a speed less than four times the rotation of the support arms 2l and 22, and the power from the motor M is only output as a linear reciprocating output that drives the extension part T. First, a rotation output is output in synchronization with the rotation of the pendulum lever L, and the drive source and the pendulum lever L are connected so that the rotation output causes the pendulum lever L to rotate synchronously. The structure is characterized by a rotational transmission.

[Effect]

Since the present invention has the above-mentioned structure, it is particularly suitable for application to a direct-lift electric rotating lift door, and the circumstances thereof will be described below. A direct lift rotating lift door is a rotating lift door that is restrained so that the lower edge of the door 1 does not follow the trajectory that 5!11 projects toward the road when it is opened/closed, but rises along a vertical trajectory, and generally the support arm 21・22 and the door ■ are connected by a pivot, and the connecting rods 21a and 22a, which are separately installed in parallel with the support arm, are connected to the support arm 2.
It is based on the method of moving relative to 1.22 (3rd
(Figure) If we look at this relative displacement as the amount of movement of the piston with respect to the crank, the amount of displacement is greatest when it is around the entire circumference of the crank, so if we convert the rotation of the support arms 21 and 22 to a speed increase of 4 times or less, The automatic drive of the connecting rods 21a and 22a corresponds to the pendulum lever L of the present invention. ) can be used as On the other hand, an electric rotating lift door refers to a rotating lift door that can open and close the door 1 using electric power, but by using a rough hook and pinion etc., it can be opened and closed not only by the doorman. It is possible to provide a rotary lift door in which the ground height of the path of the doorwork up to the S limit is gradually increased. When driving this electrically, the power transmission mechanism from the active source is converted into linear reciprocating motion, and at the same time as outputting the linear reciprocating motion, some of the energy is transferred back to the support arms 2 and 2.
2 is used as a rotating force for restoration.

If a gear S is coaxially connected to the rotating shaft of the support arms 21 and 22 as the final output, and this is rotated by a reciprocating rack, the operation will be reversible, but instead of the rack, a chain or string If the body is used, the movement is irreversible. In other words, even if the ground height of the gear S connected to the support arms 21 and 22 is simply lowered, the gear S
This means that the rotation (door closing rotation of 581) is not guaranteed. In order to make the appearance of the device more compact, it is more convenient to use a strip than a rack, so if the engagement relationship between the gear S and the chain can be made reversible, the operation will be reliable and compact. It is advantageous to be able to obtain a direct elevating rotating elevating door. Describing the operation of one embodiment of the present invention, first, the power from the drive source (motor M) is converted into reciprocating motion of the extension portion T. This reciprocating power is transmitted to the gear S that is integrated with the support arms 2↓ and 22.
The m-car S is engaged with a chain N whose one end is immovable relative to the ground. ), the gear S increases the ground height and rotates the support arms 21 and 22 in the direction of opening the door. At the same time, since the rotation of the gear S is transmitted at an increased speed to the rotation of the pendulum lever L, the movement in and out of the connecting rods 2↓a and 22a is ag! As a result, the lower edge of the door 1 is opened while following a substantially vertical trajectory. On the other hand, since the pendulum lever L is directly rotated by the decoupling source to a predetermined rotation speed, the pendulum lever L is rotated synchronously from the first drive source through the second path. , and even if the transmission system of the first path is cut off, it is possible to obtain the same effect as if it had not been cut off. Therefore, instead of a rack, chain N
Even if a vertical lift door or strip is used, reliable operation of the direct-lift electric rotary lift door can be expected as a whole.

〔Effect of the invention〕

According to the present invention, since the rotation of the pendulum lever L associated with the opening/closing operation of the door 1 is hindered by the second path from the source of shame, the movement is insufficient for power transmission through the first path. Even if there is, it is possible to avoid being affected by it overall.

Therefore, it is possible to obtain an electric rotating lift door that is compact and operates reliably.
