Description

TECHNICAL FIELD The present invention relates to a flip-up type gate used as a gate of a garage or the like.

[Technology of Conventional Example] Conventionally, an arm 2'is rotatably attached to a mounting base 4'such as a support, a gate 1'is attached to the tip of the arm 2 ', the gate 1'is closed in an upright posture, and an arm 2'is attached. A flip-up type gate in which the gate 1'is rotated to open the gate 1'in a substantially sideways posture is known, for example, from Japanese Patent Publication No. 57-53507.

[Problems to be Solved by the Invention] However, in the conventional example disclosed in Japanese Patent Publication No. 57-53507, a part of the rotation locus of the gate 1'when the gate 1'is opened and closed as shown in FIG. Moves out of the standing position (when the arm 2'is rotated in FIG. 5, 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 indicated by A in FIG.
As a result, if the standing position of the gate 1'is located at the boundary line between the site and the road, the gate 1'will rotate while opening and closing when opening and closing the gate 1 '. Therefore, there is a problem in that the position of the gate 1'standing up must be retracted from the road only by the dimension A in FIG. 5, and the site could not be used effectively.

The present invention has been made in view of the problems of the above-described conventional example, and an object thereof is that a part of the rotation trajectory of the gate protrudes outside the position in the standing posture state of the gate. The purpose is to provide a flip-up gate that can effectively use the site without the need.

[Means for Solving the Problem] In the flip-up type gate of the present invention, the tip of the upper arm 2 and the tip of the lower arm 3 are rotatably attached to the gate 1 with a vertical distance therebetween, and the attachment base 4 is attached. , The rear end of the upper arm 2 and the intermediate link 5 are independently rotatably attached coaxially, and the rear end of the lower arm 3 is rotatably attached to the end of the intermediate link 5, the gate 1, the upper and lower arms. 2, 3 and the intermediate link 5 constitute a parallel link mechanism, and the rotational angular velocity of the upper arm 2 is set to gradually decrease as the gate 1 rotates from the standing posture to the sideways posture. As the angular velocity of the gate 1 is slower than the rotational angular velocity of the upper arm 2 in the standing posture of the gate 1 and faster than the rotational angular velocity of the upper arm 2 in the lateral posture, as the gate 1 rotates from the standing posture to the lateral posture. The present invention is characterized by being set so that the speed is gradually increased, 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] Then, the gate 1 is in a standing posture (the gate 1 is closed)
In order to rotate the upper arm 2 and the intermediate link 5 to rotate the gate 1 in a lateral posture (a state in which the gate 1 is opened), the rotation angular velocity of the upper arm 2 is changed. Is set so as to gradually decrease as it turns from the standing posture to the sideways posture, and the rotation angular velocity of the intermediate link 5 is slower than the rotation angular velocity of the upper arm 2 in the standing posture of the gate 1 and in the horizontal posture. Since the setting is made such that the gate 1 gradually increases in speed from the standing posture of the gate 1 to the sideways posture so as to be faster than the rotation angular velocity of 2. Therefore, the gate 1 rotates from the standing posture to the sideways posture. In the initial stage, a force pulling on the gate 1 by the lower arm 3 acts to rotate the gate 1 upward while maintaining the almost standing posture, and the lower end of the gate 1 almost stands. It rotates without protruding from a certain closed state, and conversely, when the gate 1 is rotated from the sideways position (open state) to the upright position (closed state), the gate door 1 is in the upright position. It can be made so that it hardly protrudes beyond the position.

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

FIG. 1 shows a side sectional view of the flip-up type gate of the present invention, and FIG. 2 shows a front sectional view. Gate 1
The tip of the upper arm 2 and the tip of the lower arm 3 are rotatably supported by shafts 6 and 7 at the upper part of the back surface of the upper arm 2 with a vertical distance therebetween. A rear end of the upper arm 2 and an intermediate link 5 are coaxially and rotatably attached to a mounting base 4 such as a strut or a wall (the strut is the mounting base 4 in the embodiment of the accompanying drawings). is there. That is, in the embodiment shown in the accompanying drawings, the rear end of the upper arm 2 is fixed to the upper arm 9 fixed to the second rotating shaft 8 which is rotatably attached to the support column which is the mounting base 4. A bent central portion of the intermediate link 5 having a V-shape on the shaft 8 is rotatably supported. 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 L-shaped intermediate link 5. With the above configuration, the gate 1, the upper and lower arms 2, 3 and the intermediate link 5 constitute a parallel link mechanism. A motor 11 is housed in a support column which is the mounting base 4, and the first rotating shaft 13 is rotated by the motor 11 via a gear group 12. A first convex piece 14 is fixed to the first rotating shaft 13, and one end of a first link 15 having a V shape at the tip of the first convex piece 14 is rotatably supported by a shaft 16. The other end of the first link 15 is rotatably supported by a shaft 18 on a protruding piece 17 fixed to the second rotating shaft 8. A second convex piece 19 is fixed to the first rotating shaft 13, and the second convex piece 19 has a V-shaped second link.
One end of 20 is rotatably supported by a shaft 21, and the second
The other end of the link 20 is rotatably supported by a shaft 22 at the tip of the other piece 5b of the intermediate link 5 having a V-shape.

Now, when the motor 11 is driven, the first rotary shaft 13 rotates,
The second rotating shaft 8 rotates via the first convex piece 14, the first link 15, and the protruding piece 17, and the upper arm 2 having the rear end fixed to the second rotating shaft 8 rotates. Further, when the first rotation shaft 13 rotates, the intermediate link 5 rotates via the second convex piece portion 19 and the second link 20, and the intermediate link 5 rotates. As a result, the lower arm 3 is rotationally driven. The gate 1 is rotated from the standing posture to the sideways posture and from the sideways posture to the standing posture by the rotational drive of the upper arm 2 and the lower arm 3 to open and close. Here, the rotation angular velocity of the upper arm 2 is set to gradually decrease as the gate 1 rotates from the standing posture to the sideways posture, and the rotation angular velocity of the intermediate link 5 is set to the standing posture of the gate 1. Is set so as to be slower than the rotational angular velocity of the upper arm 2 and faster than the rotational angular velocity of the upper arm 2 in the lateral posture, so that it gradually increases as the gate 1 pivots from the standing posture to the lateral posture. is there. In order to set the rotation angular velocity of the upper arm 2 so as to gradually decrease as the gate 1 rotates from the standing posture to the sideways posture, as shown in FIG. 1, FIG. 3, and FIG. It is set by the positional relationship among the moving shaft 13, the shaft 16, the shaft 18, and the second rotating shaft 8. Further, the rotational angular velocity of the intermediate link 5 is lower than the rotational angular velocity of the upper arm 2 in the standing posture of the gate 1 and in the lateral posture, the upper arm 2 is in the horizontal posture.
In order to set the gate 1 so that it becomes faster than the rotation angular velocity of the gate 1 as it turns from the standing posture to the sideways posture, as shown in FIG. 1, FIG. 3, and FIG. It is set by the positional relationship among the first rotary shaft 13, the shaft 21, the shaft 22, and the second rotary shaft 8.

When the motor 1 is rotationally driven at a constant speed and the upper arm 2 and the intermediate link 5 are rotated while the gate 1 is in the upright posture (closed posture) as shown in FIG. Is set so as to gradually decrease as the gate 1 is rotated from the standing posture to the sideways posture, and the rotation angular velocity of the intermediate link 5 is set to be higher than that of the upper arm 2 in the standing posture of the gate 1. Since it is set to be slower and faster than the rotation angular velocity of the upper arm 2 in the sideways posture, it is set so as to gradually increase as the gate 1 turns from the standing posture to the sideways posture. In the initial stage of turning to the posture, a force pulling on the gate 1 by the lower arm 3 acts, and the gate 1 turns upward while maintaining a substantially upright posture as shown in FIG. hand, The lower end of the door 1 is rotated without protruding from the closed state where it is almost in the upright posture. When the gate 1 is rotated to a certain degree and moved upward, It gradually becomes a sideways posture such as ho, he, to, chi, re, and n. On the contrary, when the gate 1 is rotated from the sideways posture (open state) to the standing state (closed state), the gate 1 is rotated in the order reverse to the above and the gate 1 is moved out of the standing posture position. Most of them rotate without protruding.

By the way, as shown in FIG. 1 and FIG.
It is also possible to project an auxiliary arm 24 on one side, fix one end of the wire 25 to the auxiliary arm 24, and connect the other end of the wire 25 to a spring member such as a gas spring 26. A spring member such as the gas spring 26 imparts a spring force for rotating the gate 1 in the opening direction, and a motor having a small capacity can be used as the motor 11.

[Advantages of the Invention] According to the present invention, as described above, the tip of the upper arm and the tip of the lower arm are rotatably attached to the gate at a vertical distance and the rear end of the upper arm is attached to the attachment base. , And the intermediate link is rotatably attached independently on the same axis, the rear end of the lower arm is rotatably attached to the end of the intermediate link, and the parallel link mechanism is configured by the gate, the upper and lower arms, and the intermediate link. The rotation angular velocity of the upper arm is set to gradually decrease as the gate is rotated from the standing posture to the sideways posture, and the rotation angular velocity of the intermediate link is set to be slower than the rotation angular velocity of the upper arm in the standing posture of the gate. It is set so that it becomes faster as the gate rotates from the standing posture to the sideways posture so that it is faster than the rotation angular velocity of the upper arm in the horizontal posture. In the initial stage of turning from the force (closed state) to the sideways posture (open state), a force such as being pulled by the lower arm acts on the gate so that the gate turns upward while maintaining a substantially upright posture. Then, the lower end of the gate will rotate from the closed state where it is almost in the upright position without protruding, and conversely, the gate will be changed from the sideways position (open state) to the upright state (closed state). Even when rotating, the gate can be prevented from protruding beyond the standing position,
As a result, the gate is in the upright posture (closed state)
Even if it is constructed so that it stands upright along the boundary line between the site and the road, the gate will not protrude to the road side when the gate opens and closes, and the site can be effectively used. .
