Abstract

PURPOSE:To open and close a door smoothly by electrically driving and turning a rod lever installed between two shoring top-sections, rotating an axial fulcrum formed at a door support-arm base end section through the rolls of both end sections of the rod lever or lifting or lowering the axial fulcrum as required. CONSTITUTION:One ends of support arms 21, 22 are fixed on both sides of a door 1, and the other ends are supported pivotally at axial fulcra 41, 42 mounted to shorings 31, 32. A rod lever R is pivotally supported rotatably between the top sections of the posts 31, 32, and rolls Q, Q are fastened on both sides of the rod lever R. The turning force of the rolls Q, Q is transmitted over the fulcra 41, 42, and the arms 21, 22 are rotated centering around the fulcra 41, 42 and the door 1 is opened and closed. A vertical reciprocating section such as a screwing mechanism, a caterpillar, a rack and pinion, etc., is installed as required, and the fulcra 41, 42 are revolved and lifted and lowered through the rolls Q, Q. Accordingly, the door can be opened and closed without receiving torsional moment, and can also correspond to high car-height.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to external gates for buildings, particularly garage doors.

[Conventional technology]

Conventional electric rotating lift doors have expensive driving parts, so the driving part is mounted only on one support, but this does not mean there are no operational problems. In other words, since the structure is such that the electric driving force of one column is transmitted only through the door to the support arm on the opposite column side, a strong torsional moment is applied to the door, and the structure of the door is affected accordingly. , there was a burden of having to increase the specifications of the means for connecting the door and the support arm, the support arm, etc. This tendency is caused by the rotary A and descending doors (for example, the 63
-91699), it becomes even more remarkable.

[Problem to be solved by the invention]

The technical object of the present invention is to provide an electric rotary lift door that uses a unique electric drive unit without significantly increasing the structural specifications of the door.

[Means and Embodiments for Solving the Problems] The structure of an embodiment of the electric rotating lift door according to the present invention will be described with reference to a drawing. Attach one end of the support arms 21 and 22 in each direction,
The other ends of the support arms 21 and 22 are connected to a second pivot point 4 disposed on an axis X that is perpendicular to the side boundary of the garage.
1 and 42 are respectively pivoted, and when the door 1 is lowered and the main surface of the door is vertical, it is closed only once, while the above 7.1 is raised and the main surface of the door is vertical. In the case of a rotating elevator door that is designed to open at the limit when Rod rod R between the tops of struts 3" and 32
is rotatably supported with its longitudinal direction as a rotation axis, and the roller Q-Q is mounted on the support 31 so as to rotate together with the rod rod R.
・It is arranged on the rod rod R at the top of 32, and the string rod rod R is rotationally driven by electric power, and the above-mentioned rolling wheel Q-
A configuration characterized in that the rotational force of Q is rotationally transmitted along the pillars 331 and 32, and is rotationally transmitted to the rotational force of the support arms 21 and 22 about the shaft supports 41 and 42. It has become. Note that a stopper that limits the rotation stroke of the support arms 21 and 22 to approximately 90 degrees and a biasing spring means that reduces the weight of a rotating portion such as the door 1 are not shown for the sake of clarity.

[Effect]

Since the present invention has the above configuration, no matter which support column side the Iyla drive unit (motor M) is located, when the motor M rotates, the rod rod R rotates with its own longitudinal direction as the concave rotation axis. Start. This rotational force is synchronously transmitted to the left and right support arms 22, 2 through the left and right rotations IQ and Q, so the forward and reverse rotation of the motor M causes the left and right support arms 22 and 2 to be synchronously transmitted.
1 will move up and down in a balanced manner, meaning that the door 1 will be able to go up and down without being subjected to an unbalanced twisting moment, which will result in smoother operation. Therefore, the MGa specification of the door etc. can be made to a small level.

〔Effect of the invention〕

According to the present invention, the rod R is mounted between the tops of the columns 31 and 32, and the rotational force of the rod R is equally transmitted to the left and right support arms 22 and 21 via the wheels Q-Q. Therefore, as long as the rotation of the rod R can be ensured, it is possible to obtain an electric rotary elevator door that operates reliably and has a simple structure regardless of the location or number of electric drive units. In addition, in the invention of the cited publication mentioned above, the support arms 21 and 2 are located close to the inner surface of the door.
A connecting rod is fixedly installed in order to make the connecting rod 2 rigid, but according to the present invention, this is not necessary.

The invention according to claim 2 will be described below, but the [industrial application field] and [prior art] are the same as described above.

[Problem to be solved by the invention]

Technical aspects of the invention! In the invention set forth in claim 1, IB converts a portion of the rotational force transmission mechanism from the rolling wheels Q-Q to the support arms 21 and 22 into linear reciprocating motion, and uses the reciprocating power to increase the vehicle height. To provide an electric rotary lift door which can store a car, operates reliably, and has a simple structure.

[Means and Embodiments for Solving the Problems] The structure of an embodiment of the electric rotary lift door according to the present invention will be described with reference to the drawings. 32, and the linear reciprocating power is involved in raising and lowering the shaft supports 41 and 42 with respect to the above-mentioned supports 31 and 32, and at the same time, the linear reciprocating driving force is converted into linear reciprocating motion in the direction along the support arms 21 and 22. The structure is characterized in that it is adapted to take part in the rotation up and down relative to the pivot points 41 and 42, respectively.

[Effect]

Since the present invention has the above configuration, when the motor M rotates, the rod rod R1 and therefore the rolling wheels Q-Q begin to rotate, and the rotation of the rod @Q-Q is converted into linear reciprocating motion. . As a specific configuration, for example, a spiral mechanism or an endless track can be used. Since this linear reciprocating motion is transmitted to the shaft supports 41 and 42, the shaft supports 41 and 42 are raised and lowered by the rotation of the motor M. If the ground height of the shaft support points 41 and 42 becomes higher, the ground height of H&1 at the door opening limit will also become higher, making it possible to store a vehicle with a high vehicle height. In addition,
The lifting and lowering of the shaft supports 41 and 42 are simultaneously linked to the support arm 2.
If the opening rjJ rotation is also made with respect to the shaft supports 41 and 42 of No. 1 and 22, the fit can be opened and closed automatically by simply raising and lowering the shaft supports 41 and 42. A specific structure for this purpose may be, for example, a rack and binion (FIG. 3).

〔Effect of the invention〕

According to the present invention, the rolling wheels Q-Q are made to move together with the rod rod R, and the rotation of the rolling wheels Q-Q is converted into a linear reciprocating motion D-D, and the linear reciprocating motion D-D is converted to the shaft fulcrum 41. 42 and the rotation of the support arms 21 and 22 about the pivot points 41 and 42 at the same time, the structure is reliable and easy to operate regardless of the location of the electric drive unit, and is compatible with high vehicle heights. An electric rotating lift door can be obtained.
