Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to external gates for buildings, particularly garage doors, utility gates, and the like.

Conventional technology A rotating lift door is known from Japanese Patent Publication No. 57-53507, etc., but if the arm (support arm) connecting the door and the rotating shaft of the door is fixed, the height of the door above the ground when the door is opened is This caused the inconvenience that the roof of a high-roof vehicle would come into contact with the door when it was stored. If you set the pillars closer to the inside of the property in advance and choose a member with a long support arm length, you can increase the height of the door above ground when the door is opened, but if the topography of the residential area prevents setting the pillars closer to the inside of the property. There is.

Problems to be Solved by the Invention The present invention provides a rotating lift door that can increase the height of the door above the ground when the door is opened, even in the standard case where the position of the support is not particularly set toward the inside of the property. .

Means and Embodiments for Solving the Problems The structure of an embodiment of the shaft-lifting and rotating lift door according to the present invention will be described with reference to a drawing. Tani pillar 3
1, 32, and the second pillar 31, 32,
A second slider 51, 52 that is slidable in the longitudinal direction of each of the second pillars 31, 32, and a supporting shaft thereof that is disposed integrally with the second slider 51, 52. Two shaft supports 41, 42 whose X is parallel to the line segment vertically connecting the two supports 31, 32, and two supports pivotally supported by the two shaft supports 41, 42 at a portion near the center thereof. The arm 21, 22, the decorative board 1 installed across the front ends 21b, 22b of the two support arms 21, 22, and the one of the support arms 31, 32 which is close to a plane including the two support arms 31, 32. at one end 6
1a, 62a are pivotally supported, and the other ends 61b, 62b are pivotally connected to the rear ends 21a, 22a of each of the support arms 21, 22,
62, and a biasing member (in the illustration, springs 71, 7
2) When the two support arms 21 and 22 respectively rotate about the axis X of the pivot support, the front ends 21b and 22 of the support arms 21 and 22 rotate.
The b side is approximately between the horizontal direction and the vertically upward direction.
limiting the rotation stroke to within a range of 90°;
Arranged on a member (meaning the slides 51 and 52) whose movement direction is restricted to a certain direction even if it is movable with respect to a structure integrated with the ground surface outside the rotation stroke. The structure is characterized by consisting of stoppers 81 and 82 provided therein. Note that the second digit 2 and 1 used in this specification indicate the left and right sides of the support arm system, and although some parts are not shown, they are the same as those of other systems. appear.

Function Since the present invention has the above configuration, if the gravitational moment of the door is set in advance so that it is slightly superior to the moment of the opposing springs 71 and 72 when the decorative board (door) 1 is closed, the door can be opened. 1 comes into contact with stoppers 81 and 82 in the closing direction and remains stationary in the closed position. Now, when the door 1 is rotated in the opening direction, the rotation moment is generated by the springs 71 and 7.
The operating force is extremely light since the rotational moment of 2 is synergistic with the rotation moment of 2, and eventually the support arms 21 and 22 become approximately vertical, and the door 1 is in an open state. At this time, the lines of action of the floating link rods 61 and 62 are also approximately vertical, so for convenience, the shaft fulcrums 41 and 42 are 0, the other ends 61b and 62b of the floating link rods are P, and one end 61a,
If 62a is Q, the ground height of the pivot points 41 and 42 will be increased by (1-cos∠PQO)+ when the door 1 is opened, making it possible to accommodate the entry and exit of high-roof vehicles, etc. ( The sliders 51 and 52 have the pivot points 41 and 42 connected to the supports 31 and 42, respectively.
32, it has the effect of guiding freely up and down. ).

Other Embodiments The pivoting of the one ends 61, 62a of the floating linking rods 61, 62 is not limited to the supports 31, 32, and may be performed on a separate ground structure such as a side wall using the same technique. Of course, the pivot points 41 and 42 can be of either male or female construction. spring 7
1 and 72, the gravitational moment of the door 1 is applied between the slides 51 and 52 and the support arms 21 and 22 around the pivot points 41 and 42, which urges the slides 51 and 52 vertically. The other ends 61b and 62 of the floating link provide a rotational moment in the opposite direction.
The support arms 21, 22 and the floating link rods 61, 62 can be moved by applying a rotational moment around b or by interposing a spring in the extension direction between the support arms 21, 22 and the floating link rods 61, 62.
It is conceivable to apply force in the direction of separating the
Both are within the same technical scope. The same applies to the arrangement parts of the stoppers 81 and 82, including the slides 51 and 52, the support arms, the floating linking rods 61 and 62,
It does not depend on which part of the door is restricted in rotation (or movement). Structures that are integral with the ground surface are, for example, side walls and supports 31, 32, and stoppers 81, 82 protruding from these allow sliders 51, 52, support arms 21, 22, and swing links 61, 62 to be moved. If one of the travel strokes is restricted, the door 1 will eventually be moved between vertical and horizontal positions. Furthermore, as shown in the embodiment shown in FIG. It can also be arranged on members that are restricted in the vertical direction, such as sliders 51 and 52. Nameko 51,
Since 52 cannot rotate about axis X, 8
It will be clear that 1,82 functions as a stopper.

Further, as another embodiment of the biasing member, a weight may be used instead of the springs 71 and 72. In other words, the support arms 21 and 22 are extended rearward (towards the inside of the property) and a weight is added to the tips thereof. By changing the direction of force on the slides 51 and 52 using pulleys, etc., the weight can be used as a pivot point. 41, 42 or the front side of the support arms 21, 22 may be pulled up.

Furthermore, if the height of door 1 when opened increases, door 1
Although it becomes difficult to close the door 1 by touching the
By integrally providing a handle or a foot pedal for operation, it is possible to facilitate the closing operation of the door 1 from when the door 1 is opened (when the door 1 is at its upper limit). Furthermore, the pinching of limbs by the support arms 21, 22 and the floating link rods 61, 62 can be avoided by making each part into a disc shape concentric with the center of rotation and filling unnecessary gaps.

Effects of the Invention According to the present invention, since the height of the door 1 when the door is opened is higher than that of a normal rotary lift door, the height of the stored items can be increased accordingly. Furthermore, support arm 2
Compared to a rotating elevator door with longer doors 1 and 22, it occupies less ground surface area during construction, and the dead space for stored items due to the opening/closing trajectory of door 1 can also be reduced (the radius of curvature of the trajectory seen from the side) is small).
