Description

[Detailed explanation of the invention] A. Purpose of the invention This invention is designed to achieve artistic and beautiful expansion and contraction by pivoting the intersection of long and short radial rods so that the front row is connected from the left direction and the back row is connected from the right direction. The purpose is to provide a gateway.

B. Structure of the invention As shown in the drawing, the present invention has a pair of radial long and short bow rods 1 and 2 that are inclined leftward from the upper end to the lower end between the left and right opposing box-shaped frame rods A and B. A pair of parabolic long and short bow rods 3 and 4, which are connected to each other by a Z-shaped connecting plate 6 at an appropriate angle in the front-back direction, and which are opposite to this and tilt rightward from the upper end to the lower end, are connected in the front and rear directions. The long bow rods 1, short bow rods 2, short bow rods 4, and long bow rods 3 are connected in this order from front to back when viewed from the top. Support pin 7 at the upper and lower intersection of bow rods 1 and 3
and a Z-shaped connecting plate 6 installed at the top and bottom of the short bow rods 2 and 4.
The pins 5 on the opposing parts of the comrades are each supported so that their support points are aligned in a straight line, and the lengths of the short bow rods 2 and 4 are the pins 7 on the upper and lower intersections of the long bow rods 1 and 3.
This relates to the configuration of a telescopically deformable gate having an interval shorter than seven sections.

Effect of the Invention The present invention is configured as described above, and includes a box-shaped frame rod A,
A pair of parabolic long and short bow rods 1 and 2, which are inclined leftward from the upper end to the lower end, are arranged opposite each other between B.
A pair of parabolic long and short bow rods 3 and 4, which are inclined rightward from the upper end to the lower end, are connected by a Z-shaped connecting rod 6, and the support pins 7, 7 at the upper and lower parts of the long bow rods 1 and 3 and the support pins 5, 5 of the short bow rods 2 and 4 are connected by a Z-shaped connecting rod 6.
Since the bow is constructed in a straight line, the long and short bow rods 1, 2, 3, and 4 are arranged as if they are crossing each other.
It can be expanded and contracted for smooth operation, and is linked with a Z-shaped connecting rod 6, and because it is offset by the length of the connecting rod 6 as shown in Fig. 2, when it is contracted, the short bow rods 2 and 4 can be inserted between the long bow rods 1 and 3, making it compact. In addition, because the ends of the bow rods on both sides of this gate are attached between the left and right box-shaped frame rods A and B, it can be used as a telescopic gate like other telescopic gates.

Since the present invention is composed of parabolic bow rods, the gate can add aesthetic taste to the residence, and when the gate is opened, it can be reduced to a small size so that it does not take up much space. This is an effective idea.

Claims (1)

[Scope of utility model registration request] The upper and lower portions of a pair of parabolic long and short bow rods, which are inclined leftward from the upper end to the lower end, are connected between the left and right opposing box-shaped frame rods by a Z-shaped connecting plate, with an appropriate shift in the front and back direction, Opposing this, the upper and lower parts of a pair of parabolic long and short bow rods that slope to the right from the upper end to the lower end are connected by a Z-shaped connecting plate with the appropriate distance in the front and back direction, and the A pair of long-bow rods and a short-bow rod are arranged in this order, sloping leftward from the upper end to the lower end. Support the supporting pins at the upper and lower intersections of the bow rods and the pins on the opposing parts of the Z-shaped connecting plates installed at the top and bottom of the short bow rods, respectively, so that their support points are in a straight line, and the length of the short bow rod is A telescopically deformable gate that is made shorter than the spacing between the supporting pin sections at the upper and lower intersections of longbow rods.
