Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to external gates such as garage doors for buildings and the like.

Conventional technology Conventional box-shaped garage doors include shutters and so-called overhead doors (Special Publication No. 35-13334,
(Jikko No. 46-20234, etc.). However, the exterior appearance of these doors is different from the doors of garages with only pillars and roofs, which are often seen as simple covered garages these days. The upper stile of the door may not be a closed type, but may be a low open type, and it is not preferable to have a large number of connecting rods of a link mechanism intertwined in a complicated manner from the standpoint of injury to persons.

Problems to be Solved by the Invention The present invention aims to provide an open garage door that is integrated with a covered garage using a simple mechanism.
This is an improved version of the rotating lift door of No. 57-53507.
The height of the upper stile of the rotating lift door in this reference publication is 150 cm above ground.
If this is installed in a covered garage,
When the door was opened and closed, the upper stile of the door would come into contact with the beams and eave of the garage roof, making it impossible for the door to open (rotate upward).However, according to the present invention, the door can be moved against the eave. It continues to rotate even after contact with the door, allowing the door to be opened completely.

Means and Embodiments for Solving Problems The configuration of an embodiment of the rotary elevator door for a covered garage according to the present invention will be described with reference to a drawing. An axis X, two shaft fulcrums 41 and 42 arranged on the axis Two movable support arms 21, 22 and respective open ends 21b, 22b of the two support arms 21, 22.
In between, a decorative panel (door) 1 is installed across the two support arms 21 and 22, and the two pivot points 41 and 42 are supported in fixed positions relative to the ground surface S, and the garage In a rotating lift door consisting of two pillars 31 and 32 that also serve as supports for the roof 10, the door 1 rotates about a pivot Y passing through the two open ends 21b and 22b of the second support arms 21 and 22. The support arms 2 of the doors 1 and 2 are attached so that they can be moved freely.
One pivot point 21 is attached to each of the above-mentioned straddling portions 1 and 22.
c, 22c are provided, and the door 1 and the support arms 21, 22 are provided near the pivot points 21c, 22c.
A bullet f is loaded between the door 1 and the direction of the biasing force of the bullet f when viewed from the pivot points 21c and 22c.
The angle between the upper stile 1a and the support arms 21 and 22 is set in the increasing direction, and on the other hand, the angle is kept within 90° by rotation restraining pieces provided near the pivot points 21c and 22c. As restricted above door 1
is the axis X together with the two support arms 21 and 22.
When the door 1 rotates upward, the upper stile 1a of the door 1 comes into contact with the eaves 51, 52 of the garage roof 10, and the upper stile 1a resists the urging force of the elastic f to the support arms 21, 52. The structure is characterized in that it is pressed toward 22. In addition, a spring that reduces the weight of the rotating parts including the door 1 and the support arms 21 and 22, and the support arms 21 and 22
The stopper that limits the rotational stroke of the rotor is not shown because it is not relevant to the subject matter of the present invention. Further, in this specification, the second digit 2 and 1 indicate the left and right sides of the system, although some of them are not shown, but they appear the same as those of other systems.

Function Since the present invention has the above configuration, the door 1 when the door is closed (when the support arms 21 and 22 are substantially horizontal)
The support arms 21 and 22 are restrained by the biasing force of the bullet f in the direction of the arrow F (the door 1 is free to rotate from the orthogonal state in the direction against the bullet f in the opposite direction of the arrow F). Also, due to the bullet f, door 1
The reason why the support arms 21 and 22 do not rotate beyond the orthogonal state is due to the effect of the trapezoidal rotation prevention piece shown at the left end of the lower surface of the support arm 21 in FIG. 3, for example. ). Now, when the door 1 rises in the door opening direction, the upper stile 1a comes into contact with the eaves 51, 52 of the garage roof 10, the beams, etc., and the door 1 and the support arms 21, 22 are integrated like a conventional rotating lift door. However, in the case of the rotary lift door of the present invention, when the door 1 is firmly fixed to the axis Up to the stroke (approximately 45 degrees), the external force energy of one rotation of the door relative to the axis
It is rotated in the opposite direction of the arrow F around the center (against the bullet f), and the energy is stored in the bullet f. Furthermore, when the door 1 rotates upward with respect to the axis (The accumulated energy corresponding to the increase in the amount of energy will be released.) As the door 1 approaches its opening limit, the door 1 becomes approximately horizontal. During this time, due to the principle of leverage, the contact pressure of the eaves upper stile resisting the biasing force of the bullet f may be extremely small, and the energy accumulated in the rotating biasing force f when the door is fully opened is teeth,
Since it has a structure that does not easily expand, it is stable even in the absence of external force, and there is no danger of sudden explosions (external force from the rotation of door 1 about the axis The door 1 resists the striations f, and sometimes adapts to the striations f, but considers the striations f as a driving source.
This describes the circumstances in which it is difficult to establish a mechanical relationship in which the rotation about the axis X is regarded as a load. ).

Other Embodiments The rotating elevator door of the embodiment described above has the following effects:
Since the only drag force is the biasing force of the bullet f, when the external force increases, the upper stile 1a of the door 1 will turn inward of the property. In this way, when the door is opened, stability is maintained (prevention of the above-mentioned turning) against an external force directed inward of the property, rather than an external force in the opening direction of the door 1 (in the direction of upward rotation of the support arms 21 and 22 with respect to the axis X). To do this, you just need to make some additions to the configuration.

That is, as shown in FIG. 3, when the pin 1b integrated with the pivot Y or the support arms 21 and 22 is biased clockwise in FIG. , a cam 6 which is prevented from rotating clockwise relative to the pin 1b by a restraining piece 7 integrally provided with the door 1, and at the same time prevents the door 1 from rotating in the direction opposite to the arrow F relative to the pivot Y ( The arrangement position of pin 1b is the number 10 with respect to the axis Y of door 1.
Consideration must be given to locating it in such a way that it does not interfere with the degree of rotation. ), on the other hand, if a control rod 8 is provided that is slidably and loosely fitted into the door 1 and extends from directly above the top stile 1a toward the top surface of the cam 6, the door 1 rotates upward relative to the axis X, and the top stile 1a When the door contacts the eaves 51 and 52, the control rod 8 first contacts the eaves, and the control rod 8 rotates the cam 6 in the counterclockwise direction (FIG. 3) to rotate the cam 6 relative to the pivot axis Y of the door 1. Automatically unlocks the prohibition of rotation in the opposite direction of arrow F. Therefore, even after the door 1 comes into contact with the eaves 51 and 52, the door 1 takes a step in which the biasing force of the bullet f is increased as described above (in the second half of the opening process, the biasing force of the bullet f is reversed). ), door 1 continues to be opened without any hindrance. If the control rod 8 continues to push the cam 6 while the upper stile 1a is in contact with the eaves 51 and 52 (that is, during the latter half of the door opening stroke from the closing limit), the above steps will naturally be completed. Automatic reversal is also possible. At the closing limit, the door 1 becomes perpendicular to the support arm, and the free end of the cam 6 also becomes perpendicular to the door 1, so even if an external force from inside the property is applied to the upper stile 1a at the closing limit, Door 1 does not pivot around axis Y.

Effects of the Invention According to the present invention, even if the upper stile 1a is an open door whose height above the ground is not very high, and the revolving lift door contacts the garage roof when it rotates upward,
The door can be opened and stored in the garage smoothly. Moreover, since the outermost supports of a covered garage are usually set several tens of centimeters inward from the outer edge of the roof, the supports of the garage roof and the pivot points 41, 4
In the configuration of the present invention which also serves as a support member for the ground surface S in No. 2, the lengths of the support arms 21 and 22 and the ground heights of the pivot points 41 and 42 can be made approximately equal. In this relationship, the depression angle of the lower stile of the door 1 as seen from the axis This does not significantly impair the practicality of Door 1.), the cosine of the above angle of depression is approximately 1.0 (cos40° = 0.766), and the lower stile of the door during the process of opening and closing the door.
It can be said that there is no disadvantage that the trajectory of the door protrudes greatly toward the road side, unlike conventional overhead doors. When the upper stile 1a contacts the eave and rotates the door 1 in the opposite direction of the arrow F around the pivot Y, it is as if the lower stile protrudes toward the road, but the pivot point 21c , 22c rise and rotate inward about the axis X, so it becomes a counterbalancing phenomenon and does not protrude much.
