Abstract

PURPOSE:To utilize a site effectively by rotatably installing the front end of an upper arm and the front end of a lower arm to the door of a gate and rotatably mounting the upper and lower arms independently to an intermediate link respectively. CONSTITUTION:The front end of an upper arm 2 and the front end of a lower arm 3 are set up rotatably to the door of a gate 1 at a distance in the vertical direction, and the rear sections of the upper and lower arms 2, 3 and an intermediate link 5 are fitted rotatably to a mounting base section 4 respectively. The rotational angular velocity of the upper arm 2 is set so as to be gradually slowed with revolution from the erect attitude of the door of the gate 1 to a sideways attitude. The rotational angular velocity of the intermediate link 5 is set so as to be made slower than that of the upper arm 2 at the erect attitude of the door of the gate 1 and faster at the sideways attitude. Accordingly, extrusion to the road side of the door of the gate at the time of the opening and closing operation of the door of the gate can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flip-up gate used as a gate for a garage or the like.

[Conventional technology] Conventionally, when installing a support, etc., the arm 2' is rotatably attached to the base 4', the gate 1' is attached to the tip of the arm 2', the gate IR1' is closed in an upright position, and the arm 2' is attached to the base 4'. A flip-up type gate is known, for example, from Japanese Patent Publication No. 57-53507, which opens the gate 1' by moving it three times in a substantially horizontal position.

[Problems to be Solved by the Invention] However, in the conventional example shown in Japanese Patent Publication No. 57-53507, when opening and closing the gate 1', as shown in FIG. (In Fig. 5, when the arm 2' is rotated, the upper and lower ends of the gate 1' rotate as shown by the two-dot chain line, but the rotation locus of the lower end is Gate 1 only for the portion shown by A in Figure 5
As a result, if the standing position of the gate 1' is located on the boundary line between the site and the road, the gate 1' will protrude into the road when the gate 1' is opened or closed. There is a problem that the gate 1' rotates, and therefore, the standing position of the gate 1' must be set back from the road by the dimension A shown in FIG. 5, which makes it impossible to use the site effectively.

The present invention was invented in view of the problems of the conventional example described above, and its purpose is to prevent a portion of the rotation locus of the gate from protruding outward from the position of the gate in the upright position. We provide a flip-up gate that allows you to use the site effectively.

[Means for Solving the Problems] In the flip-up gate of the present invention, the tips of the upper arm 2 and the tips of the lower arm 3 are rotatably attached to the gate 1 at a vertical distance apart, and the attachment is done at the base. 4, the rear end of the upper arm 2 and the intermediate link 5 are coaxially attached so as to be rotatable independently, and the rear end of the lower arm 3 is rotatably attached to the end of the intermediate link 5. The arm 2.3 and the intermediate link 5 constitute a parallel link mechanism, and the rotation angular velocity of the upper arm 2 is set to gradually become slower as the gate 1 rotates from the upright position to the horizontal position. The rotational angular velocity of upper arm 2 is
The rotational angular velocity of the upper arm 2 is set to be slower than the rotational angular velocity of the upper arm 2 in the horizontal position and faster than the rotational angular velocity of the upper arm 2 in the horizontal position, and gradually increases as the gate 1 rotates from the upright position to the horizontal position. and
By adopting such a configuration, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[Operation] Therefore, the gate 1 is placed in the upright position (the gate 1 is closed) v9.
) to turn the gate 1 into a horizontal position (opening the gate 1), the upper arm 2 and the intermediate link 5 are rotated to rotate the gate 1. The rotational angular velocity of the intermediate link 5 is set to be slower than the rotational angular velocity of the upper arm 2 when the gate 1 is in the standing posture and upward when the gate is in the horizontal posture. The rotation angular velocity of the gate 1 is set to be faster than the rotational speed of the arm 2, so that it gradually becomes faster as the gate 1 rotates from an upright position to a sideways position. At the beginning of the movement, a force such as being pulled by the lower arm 3 acts on the gate 1, causing the gate 1 to rotate upward while maintaining an almost upright position. In addition, when the gate 1 is rotated from the horizontal position (open state) to the upright state (closed state), the gate 1 rotates from the upright position without protruding. It can also be made so that it does not protrude to the outside.

[Examples] The present invention will be described in detail below based on examples shown in the accompanying drawings.

FIG. 1 shows a side sectional view of the flip-up gate of the present invention, and FIG. 2 shows a front sectional view. At the upper part of the back surface of the gate 1, the tips of an upper arm 2 and a tip of a lower arm 3 are rotatably supported by shafts 6.7 at a vertical distance apart. To attach a column or wall, etc., rotate the rear end of the upper arm 2 and the intermediate link 5 independently on the same axis on the base 4 (in the example in the attached 1-inch drawing, the column is attached to the base 4). It can be installed freely. In other words, in the embodiment shown in the attached drawings, the rear end of the upper arm 2 is fixed to the upper arm 9 fixed to the second rotation shaft 8 which is rotatably attached to the column which is the base 4. The bending center portion of the intermediate link 5 having an oval shape is rotatably supported on the moving shaft 8. A lower arm 23 fixed to the rear end of the lower arm 3 is rotatably supported by a shaft 10 at the end of one piece 5a of the wedge-shaped intermediate link 5. By configuring as above, gate 1
, the upper and lower arms 2.3, and the intermediate link 5 constitute a parallel link mechanism. A motor 11 is installed inside the column that is the base 4, and the motor 11 rotates a first rotation shaft 13 via a gear group 12. A first convex piece part 14 is fixed to the first rotation shaft 13, and a first link 1 having an F-shape at the tip of the first convex piece part 14
5 is rotatably supported by a shaft 16, and the other end of the first link 15 is fixed to the second rotation shaft 8.
7 is rotatably supported by a shaft 18. Also, the first
A second convex piece 19 is fixed to the rotation shaft 13, and one end of a second link 20 having a F-shape is rotatably supported on the second convex piece 19 by a shaft 21. Yes, 2nd link 20
The other end is rotatably supported by a shaft 22 at the tip of another piece 5b of the intermediate link 5 having a box-like shape.

Now, when the motor 11 is driven, the first rotation shaft 13 rotates, the second rotation shaft 8 rotates via the first convex piece 14, the first link 15, and the protrusion piece 17, and the second The upper arm 2 whose rear end is fixed to the rotation shaft 8 rotates, and when the first rotation shaft 13 rotates, one second convex piece and the second link 20 are rotated. The intermediate link 5 rotates through the intermediate link 5, and as the intermediate link 5 rotates, the lower arm 3 is driven to rotate. By rotationally driving the upper arm 2 and the lower arm 3, the gate 1 is opened and closed by rotating from the upright position to the sideways position and from the sideways position to the upright position. Here, the rotational angular velocity of the upper arm 2 is set to gradually become slower as the gate 1 rotates from the upright position to the sideways position, and the intermediate link 5
The gate 1 rotates from the standing posture to the sideways posture so that the turning angular velocity of the gate 1 is slower than the turning angular velocity of the upper arm 2 when the gate 1 is in the standing posture, and faster than the turning angular velocity of the upper arm 2 when the gate 1 is in the sideways posture. The settings are set so that it gradually becomes faster. To set the rotational angular velocity of the upper arm 2 so that it gradually becomes slower as the gate 1 rotates from the upright position to the sideways position, the first step is as shown in Figures 1, 3, and 4. It is set based on the positional relationship between the moving shaft 13, the shaft 16, the shaft 18, and the second rotation shaft 8. In addition, the rotational angular velocity of the intermediate link 5 is changed from the standing posture of the gate 1 to the sideways direction so that the rotational angular velocity of the intermediate link 5 is slower than the rotational angular velocity of the upper arm 2 when the gate 1 is in the standing posture and faster than the rotational angular velocity of the upper arm 2 when the gate 1 is in the standing posture. To set it so that it gradually becomes faster as it rotates to the posture,
As shown in FIG. 4, the first rotation shaft 13, the shaft 21, the shaft 22,
This is set based on the positional relationship of the second rotation axis 8.

However, as shown by A in Figure 3, the gate 1 is in the upright position (
When the upper arm 2 and the intermediate link 5 are rotated by rotating the motor 11 at a constant speed in the closed position (closed position), the rotational angular velocity of the upper arm 2 is changed to rotate the gate 1 from the upright position to the sideways position. Therefore, the rotational angular velocity of the intermediate link 5 is set to gradually become slower, and the rotational angular velocity of the intermediate link 5 is set to be slower than the rotational angular velocity of the upper arm 2 when the gate 1 is in the upright position, and faster than the rotational angular velocity of the upper arm 2 when the gate 1 is in the horizontal position. As the gate 1 rotates from the upright position to the sideways position, it is set to gradually become faster. Therefore, at the beginning of the rotation of the gate 1 from the upright position to the sideways position, the lower arm 3 pulls the gate 1. As a result of the force acting on the door 1, the gate 1 rotates upward while maintaining an almost upright position as shown in Figure 3, and the lower end of the gate 1 comes out of the closed state where it is almost in an upright position. There is a mechanism that rotates without protruding, and when the gate 1 rotates to a certain extent and moves upward, it gradually turns sideways as shown in Figure 3: mouth, ha, two, ho, he, to, chi, wa, nu. It becomes an attitude. Conversely, when rotating the gate 1 from the horizontal position (open state) to the upright state (closed state R), the gate 1 rotates in the reverse order to the above, and the gate 1 moves outward from the upright position. By the way, as shown in FIGS. 1 and 2, an auxiliary arm 24 is provided protruding from the second rotation shaft 8, and one end of the wire 25 is attached to this auxiliary arm 24. is fixed, and the other end of the wire 25 is connected to the gas spring 2.
It may be connected to a spring member such as 6. A spring member such as the gas spring 26 is given a spring force to rotate in the direction in which the gate 1 is opened, and a motor with a small capacity can be used as the motor 11.

[Effects of the Invention] In the present invention, as described above, the tips of the upper arm and the tip of the lower arm are rotatably attached to the gate at a vertical distance apart, and the attachment is made by attaching the tips of the upper arm to the base at the rear of the upper arm. The end and intermediate links are attached coaxially and rotatably independently, and the rear end of the lower arm is rotatably attached to the end of the intermediate link, and the gate, upper and lower arms, and intermediate link form a parallel link mechanism. , the rotational angular velocity of the upper arm is expressed as becoming gradually slower as the gate rotates from the upright position to the horizontal position, and the rotational angular velocity of the intermediate link is expressed as being slower than the rotational angular velocity of the upper arm when the gate is in the upright position. The rotation angular velocity is set to be slower and faster than the rotation angular velocity of the upper arm in the sideways position, so that it gradually becomes faster as the gate rotates from the standing position to the sideways position, so from the standing position (closed state) of the gate In the initial stage of rotation when the gate is turned to a sideways position (IjF! state), a pulling force is applied to the gate by the lower arm, causing the gate to rotate upward while maintaining an almost upright position. It rotates without protruding from the closed position where the lower end is almost in the upright position, and conversely, when the gate is rotated from the horizontal position (open state) to the upright position W3 (closed state). The gate can be positioned so that it does not protrude beyond its upright position, and as a result, when the gate is in the upright position (closed state), it can be positioned upright along the boundary line between the site and the road. Even if the gate is constructed in such a way, the gate will not protrude into the road side when the gate is opened and closed, and the site can be used effectively.
