Description

Description: TECHNICAL FIELD The present invention relates to a gate, and more particularly to a flip-up pivot locus correction device for a gate that is a flip-up type.

[Conventional technology]

For example, the flip-up type gate, which is often installed at the carport entrance side, is a vertical plate-shaped partition with various designs. While each supporting arm is fixed, the rear end of this supporting arm is pivotally attached to the upper ends of the left and right columns, which are approximately the same height as the gate body, so that they can be rotated 90 degrees, respectively. Is to pivot up the gate body between a vertical state (closed) and a horizontal state (opened), with the shaft-attached portion on the column side as the center position and the length of the support arm as the radius. .

[Problems to be Solved by the Invention]

However, in this case, the distance between the pivotal mounting position of the pivot point and the lower end of the gate body corresponds to the hypotenuse of the right triangle, so to speak, naturally, rather than the length of the support arm, which is the radius of the pivot. As a result, the gate body, especially the lower end of the gate body, largely protrudes outward when opening and closing.

For this reason, this kind of flip-up type gate is installed so that the gate main body is located inside with a large space remaining corresponding to the protruding amount at the time of flip-up rotation with respect to the site boundary. Is necessary, which is a big limitation for effective use of the site.

The present invention has been made in view of such problems,
It is an object of the invention to provide a gate-up flip-and-rotation locus correction device which can reduce the protrusion of the gate main body at the time of flip-up rotation.

[Means for Solving the Problems]

According to the present invention, the gate body is supported by a pair of upper and lower support arms, and the rear end of the lower support arm is detachably connected to the upper support arm by a moving guide and a connecting link. That is, according to the present invention, the present invention is provided with a moving guide which is provided on each of the left and right struts so as to face each other, and which is vertically curved, meandering or linearly arranged; An upper support arm having a rear end rotatably and fixedly attached to the support at a fixed position above the end, and a tip turned to a position near the upper end of the upper support arm and above the upper end of the gate body side. A lower support arm paired with an upper support arm, which is movably fixed to a shaft and has a moving projection arranged at the rear end engaged with and guided by the moving guide; Support While being fixed to the frame, the above-mentioned moving guide and a connecting link in which a moving projection of the lower supporting arm is engaged and guided in a simultaneous restraining manner are provided on a cross guide in the longitudinal direction arranged forward so as to always intersect with the moving guide. The present invention relates to a flip-up rotation locus correction device for a gate, which is characterized by the following.

[Action]

According to the present invention, when an external force in a flip-up direction is manually or electrically applied to the gate body whose fixed position is the closed state, the upper support arm is rotated upward and simultaneously the lower support arm and the connecting link are respectively moved upward. The rear end of the lower support arm is simultaneously restrained by the movement guide and the cross guide by the upward rotation of the connecting link, and is moved upward and downward with respect to the upper support arm. , Initially in the proximity direction, and later in the separation direction.

Therefore, the gate main body, which is going to rotate and rise in an arcuate path by the upper support arm, is simultaneously pulled up to the column side in correspondence with the displacement amount in the lower part thereof, and then is inclined again so as to be sent out again. The angle is controlled.

As a result, the lower end of the gate body absorbs the protrusion from the fixed position when the door is closed to the predetermined upper position, and the vertical approximate locus or protrusion is significantly reduced depending on the displacement amount. Ascends to draw an elliptical locus, and then returns to an arc locus and is opened horizontally on the pillar, and closing closes to a fixed position by drawing the opposite locus. To do.
