Abstract

PURPOSE: To facilitate the conversion execution by arranging a sliding mechanism movable along a support arm, and giving a counter-gravity moment with respect to the axis to an urging member to increase the change as the positional change of a moving piece. CONSTITUTION: One ends 21a, 22a of an electric rotary elevating/lowering door attachment are pivotably supported by fulcrums 41, 42 of the axis X of rotation, and comprises a door 1 in the direction across the support arms 21, 22, supports 31, 32, and urging members 61, 62 to give the moment in the direction of the counter-gravity. A sliding mechanism D movable along the support arm 22 at the relative position by the electric driving force is arranged, and the counter- gravity moment is given to the X-axis by engaging the urging 62' between a moving piece P and a structure on the ground outside the support 32. The change in the reaction moment accompanied by the positional change of the moving piece P is sufficiently increased for elevating/lowering a turning part K. The manual door can be safely and easily converted to the electric rotary elevating/lowering door.

Description

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

[Conventional technology]

Although various electric rotary lift doors have been proposed, none have been found in which an electric drive part can be added or detached as an attachment (additional or attached structure).

The advantage of being able to add or remove the electric drive unit is that
This means that regardless of the structural dimensions of each part of an existing manual revolving door, it is possible to add an electric drive part by retrofitting (i.e. upgrading from a manual type to an electric revolving door), if necessary. It also has the advantage of being able to be converted back to a manual type, so even if it is just an attachment member, it can be expected to be distributed and sold as a product.

[Problem that the invention seeks to solve]

The technical problem of the present invention is to devise a means for safely and easily converting a manual revolving door into an electric revolving door without the need for a clutch, and to develop a structure using the same as a concrete product. The goal is to make it come true.

[Means and Embodiments for Solving the Problems] The configuration of an embodiment of the electric rotating lift door according to the present invention is described with reference to a drawing. Two support arms 21 and 22 whose one ends 21a and 22a are pivotally supported by two shaft fulcrums 41φ42 disposed on the axis X, and are rotatable in a plane intersecting the axis X. A decorative panel (door) L is installed between the open ends of the support arms 21 and 22 in a direction intersecting with the support arms 21 and 22, and an anti-gravitational force that counteracts the gravitational moment shown by the rotating parts K such as the above-mentioned 22. One or more biasing members 61 and 62 that provide a moment in the direction
In the rotary elevator door comprising: at least one of the support arms 22, the relative position of the support arm 22 can be appropriately moved along the support arm 22 by electric driving force;
In addition, a sliding mechanism whose movement position can be freely selected is disposed, and a position is provided between the slider P in the sliding mechanism and the ground structure disposed outside the support column 32. The biasing member 62' is configured to apply an anti-gravitational moment to the axis X in a direction that counteracts the gravitational moment exhibited by the rotating portion K. The structure is characterized in that the amount of change in the anti-gravitational moment caused by a change in the position of the mover P in the sliding mechanism is made large enough to be involved in the movement up and down of the rotating part. Note that a stopper is separately provided to limit the rotation stroke of the support arms 21 and 22 over a range of 90' from the horizontal direction to the substantially vertical direction, but is not shown for the sake of clarity. Also, the second digit 1 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 configuration, one biasing member 6
By appropriately selecting the load and spring characteristics of 2', if the slider P is moved closest to the door 1 when the door is closed, the moment of the biasing member 62' relative to the axis X increases, and the door 1 rises. and reaches the opening limit. This time, if the slider P is moved to the pivot point 41 side, the door starts to descend for the opposite reason to that described above.

Therefore, if the mover P can be electrically driven, the opening/closing operation of the door can be achieved by electrically driving.

If the movable element P has a spiral structure, for example, it is possible to forcibly move the movable element P even if it resists the load of one of the urging members 62'. In addition, the present invention provides an attachment using two elements: (10) a sliding mechanism at the upper end of the biasing member 2' and a means for fixing the lower end of the biasing member 62' to the ground surface (this may be to an existing column). Because of this structure, it has the advantage that it can be easily attached to manually operated rotary lift doors of various different shapes that have already been constructed. Therefore, conversion from a manual type to an electrically driven rotating lift door can be performed without requiring any replacement materials other than attaching the electric rotating lift door attachment according to the present invention. In addition, in the conventional product, if an external force acts on the door 1 and tries to hinder the movement of the door 1 while the door 1 is being raised or lowered by electric drive, there is a risk of damage to the motor M or the transmission system, but in the present invention, There is no risk of causing any particular harm as the state will simply be in an equilibrium resting state (a general method of electronically shutting off the drive motor after detecting a movement disturbance is known, but the need for such an extra electronic circuit is Nor.). Furthermore, when stopping the mover P,
If the circuit is configured in advance so that the slider P automatically follows and stops using an auxiliary power source at approximately the midpoint of the displacement of the slider P, no modification or clutch operation of the electric lift door will be necessary. Even if the electric driving force is cut off due to a power outage, there will be no inconvenience because it can be operated as a manual rotary lift door without having to do so. 1” force member 61・
61' is not necessarily limited to a compression spring as long as the moment effect is the same. The present invention
A biasing member 6 with a long stroke is also used for a rotating elevator door in which the axis of rotation X of the rotating part moves up and down as the door 1 is opened and closed.
1' and 62' can be applied, and the lower engaging ends of one of the biasing members 61' and 62' can be engaged with the supports 31 and 32 because they are a structure integrated with the ground surface. Of course.

Effects of the Invention According to the present invention, since the parts are simply configured as an electric rotating lift door attachment, it is easy to convert an existing manual type rotating lift door to an electric rotating lift door, and safety after construction is considered. This can be achieved by means.
