The inner wall 29 of each connecting member main body 27 has openings 37 at four corners as shown in FIG. In the opening 37 of the connecting member main body 27 fixed to the upper end of the vertical bar 13, the upper end of a decorative member 38 made of a substantially U-shaped cross section is inserted so as to be slidable in the longitudinal direction of the decorative member 38. The lower end of the decorative member 38 is inserted into the opening 37 of the connecting member main body 27 fixed to the lower end of the bar 13 so as to be slidable in the longitudinal direction. With this configuration, the decorative member 38 extends in the vertical direction along the vertical bar 13 and is located on both the left and right sides of the vertical frame member 6. The opening 37 of each connecting member main body 27 does not necessarily have to be provided separately. The two openings 37, 37 at both ends of the connecting member main body 27 are made into one, and the space between the two decorative members 38 inserted therein is formed. An elastic body such as rubber may be attached to the gap.

The decorative member 38 is made of a light metal such as aluminum and has elasticity as a whole, and has inwardly folded portions 39 at both ends. The decoration member 38 has a slightly shorter overall length than the inner dimension between the outer walls 30 of the pair of connection member main bodies 27 facing each other up and down, and
As shown in FIG. 8B, which is a cross-sectional view showing the mounting state of the connecting member main body 27, only in the upper connecting member
A gap is formed between the outer wall 30 and the end surface of the decorative member 38.

Each of the decorative members 38 is provided with an engaging member 40 at a position spaced a predetermined distance from the fixed pivot 19 with respect to each of the inclined links 11 and 12.
(FIG. 1). This connection position is a position where the decoration member 38 straightened between the connection members 14 and 15 intersects the inclined links 11 and 12 when the gate body 3 is contracted, and the decoration member 38 and the inclined link A pin made of a round pipe is used as the engagement tool 40 to connect the pins 11 and 12 (FIG. 5).

The engaging member 40 has one end fixed to the inner side walls of the inclined links 11 and 12 formed of square pipes with rivets 41, and the other end formed from the folded portion 39 of the decorative member 38 into a U-shaped curved shape.

Further, the member connecting the decorative member 38 and the inclined links 11 and 12 is not limited to a pin-shaped member such as a pipe, and a member having an appropriate shape may be appropriately selected and used.

Next, the operation for opening and closing the telescopic gate of the embodiment will be described. When the gate body 3 is to be contracted from the state shown in FIG. 1, the handle 9 may be pushed toward the suspension-side column 1. Then, in FIG. 1, each right-upward inclined link 11 rotates counterclockwise around the fixed pivot 19,
While the upwardly inclined link 12 tilts clockwise, the interval between the vertical frame members 6 becomes narrower, and can be reduced to the state shown in FIG. When the gate is contracted in this manner, the engaging member 40 connecting the decorative member 38 and the inclined links 11 and 12 is fixed to the fixed pivots 19 with the inclination of the inclined links 11 and 12. When the horizontal movement with respect to the pivot 19 is moved in the direction in which the horizontal space becomes small, and the state shown in FIG. 3 is reached, each decorative member 38 is in a state of extending straight along the vertical bar 13.

Conversely, when the gate body 3 is to be extended from the state shown in FIG. 3, the handle 9 may be pulled toward the door stop side support 2 so that each of the inclined links 11 and 12 is connected to the gate body 3. The distance between the vertical frame members 6 increases while tilting in the direction opposite to the direction in which is contracted. If the locking device is locked when the door stop side end frame 4 reaches the door stop side support 2, the doorway of a garage or the like can be closed.

When the gate is closed in this manner, the decorative member 38 is provided with an engagement member 40 for connection with each of the inclined links 11 and 12.
Is gradually distorted in an arcuate shape in order to move away from the fixed pivot 19 in the horizontal direction, and the degree of curvature becomes maximum when the gate is closed. If it is desired to further increase the degree of curvature at this time, the distance between the fixed pivot 19 and the engagement tool 40 may be set wider, but in this case, the engagement tool 40 is moved to the inclined links 11 and 12. If it is provided at a position shifted from the center in the width direction, when the gate body 3 is contracted, the decorative member 38
It is possible to make a straight state.

When the door is extended to close the doorway, the decorative member 38 is curved, so that the outer dimensions of each pair of decorative members 38 located on the left and right with respect to each vertical frame member 6 are increased, and If this dimension does not change even when contracted, the opening width of the entrance of the garage or the like becomes small, but when the gate is contracted in the above embodiment, each decorative member 38 is straightened and its outer dimension is narrowed, Inconvenient such that the opening width of the doorway becomes small when shrinking does not occur.

As described above, in the gate of this embodiment, the interval between each pair of decorative members 38 arranged on the left and right sides with respect to the vertical frame member 6 changes in conjunction with the expansion and contraction of the pantograph mechanism 7. Thus, a visually remarkable effect, which is not seen in the conventional gate, that is, the appearance is different when the gate is closed and when the gate is opened can be obtained. On the other hand, the vertical bar 13 is disposed between the right-upward inclined link 11 and the left-upward inclined link 12 of the pantograph mechanism 7, and the decorative member 38 is arranged before and after the pantograph mechanism 7, so that it is a design member and can be freely designed.
