Guide grooves 17 are formed along the longitudinal direction on the opposing surfaces of the vertical lattice members 15a and 15b. Similarly to the lattice material 3, the handle lattice 10 is also configured by connecting the upper end portions of the two vertical lattice materials 15 a and 15 b arranged at the front and back with a horizontal lattice material 16.

  As shown in FIG. 4, the link 4 includes a plurality of one side link members 5 which are located on the front side and inclined to the right and the other side link members 6 which are located on the rear side and are inclined to the right. The crossing portions of the link members 5 and 6 are pivotally attached to the front and rear pins 7, 18 and 27 so as to be relatively rotatable. Between the one side link member 5 and the other side link member 6, as shown in FIG. 5, the space | interval 19 is provided in the front-back direction. As shown in FIG. 4, the intermediate pin 7 among the three pins 18, 7, 18 that overlap each grid material 3 in the prospective direction is a fixed pin 7 fixed to the vertical grid materials 15 a, 15 b. The upper and lower pins 18 and 18 are sliding pins 18 and 18 which are guided by the guide grooves 17 of the vertical lattice members 15a and 15b to slide up and down. As shown in FIGS. 1 to 3, a cylindrical sleeve 20 made of resin is provided around the fixing pin 7 between the one side link member 5 and the other side link member 6.

As shown in FIGS. 1 to 3, this telescopic gate has a single guide member 2 provided horizontally from the lattice material 3 a side at the door end side toward the door bottom side. The guide member 2 is a fixing pin 7 between the one side link member 5 positioned on the front side and the other side link member 6 positioned on the rear side, and fixing the link 4 to the lattice material 3a at the door end side end. And the link 4 is disposed across the fixing pin 7 that fixes the door-side lattice material 3b. As shown in FIG. 2, the guide member 2 is formed so that the width in the front-rear direction is substantially the same as the distance 19 between the one side link member 5 and the other side link member 6. As shown in FIG. 1, the lower surface of the guide member 2 is in contact with or close to the upper end of the sleeve 20 around the fixing pin 7.
As shown in FIG. 3, the guide member 2 is formed by using a hollow extruded shape member having a substantially rectangular cross section made of aluminum, and a cushioning material formed of a resin that is slippery on the upper and lower sides of the front and rear sides. 21 is provided along the longitudinal direction, and the cushioning material 21 is in contact with or close to the one side and the other side link members 5 and 6. As shown in FIGS. 1 and 2, a cap 22 made of resin is attached to the tip of the guide member 2, and the cap 22 is formed in a tapered shape with the upper, lower, left and right surfaces as inclined surfaces 23.
The guide member 2 extends from the fixing pin 7 of the lattice material 3b (second lattice material from the door end side) of at least one of the lattice materials 3a at the door end side end in a state where the gate body 1 is extended. As long as it extends to the buttocks side, as shown in FIG. 1, the present embodiment is about 50 mm from the fixing pin 7 of the lattice material 3 b on one door bottom side of the lattice material 3 a at the door end side end. Protrudes to the side. When the gate body 1 is contracted, the guide member 2 penetrates to the door bottom side of the gate body 1 as shown in FIG.
Moreover, although the guide member 2 may be attached to the lattice material 3a at the door end side end portion, in this embodiment, the guide member 2 is attached to the pulling lattice 10. Specifically, as shown in FIGS. 2, 3, and 8, a horizontal beam 24 is installed on the vertical lattice members 15 a and 15 b of the handle grid 2, and screws 25 inserted from the door end side into the horizontal beam 24 are guided to the guide member 2. The guide member 2 is attached by being screwed into the tapping hole 26 formed in the above.

As described above, in the telescopic gate, the guide member 2 is attached horizontally to the handle lattice 10 provided at the door end side end portion of the gate body 1 toward the door bottom side, and the guide member 2 is moved forward. The guide member when the gate body 1 is extended and contracted by holding the front or rear puller 11 by being arranged between the one side link member 5 located and the other side link member 6 located on the rear side. 2 prevents the handle lattice 10 from tilting in the horizontal plane, so that the gate body 1 can be smoothly expanded and contracted, and the lock 12 can be prevented from being defectively hooked. When the gate body 1 is contracted, the lattice members 3, 3,... Are held in the front-rear direction by the guide member 2, so that deformation of the gate body 1 and generation of noise due to wind pressure can be prevented. In addition, the guide member 2 straddles over the fixing pin 7 that fixes the link 4 to the lattice material 3a at the door end side and the fixing pin 7 that fixes the link 4 to the lattice material 3b on the door bottom side. Therefore, it is possible to prevent the guide member 2 from hanging down without separately attaching a part for receiving the guide member 2. Since this telescopic gate only needs to attach one guide member 2 to the door end side end, the number of parts is small and the construction is easy. Since the guide member 2 is located at the center of the gate body 1 in the front-rear direction, the guide member 2 is not conspicuous and a hand or clothes are not easily caught on the tip of the guide member 2.
Further, the telescopic gate is provided with a handle lattice 10 at the end of the gate body 1 on the door end side, and the guide member 2 is attached to the handle lattice 10, so that the parts for attaching the guide member 2 to the gate body 1 are attached. No drilling or the like is required, and the guide member 2 can be disposed simply by attaching the handle grid 10 to the gate body 1, so that the construction is further facilitated.
Since the guide member 2 is formed of a hollow aluminum shape, the guide member 2 can be reduced in weight and strength. Since the resin cushioning material 21 is provided on the front and rear surfaces of the guide member 2 along the longitudinal direction, the metal does not rub against each other, and the gate body 1 can be expanded and contracted more smoothly.
In the present embodiment, as shown in FIG. 1, the guide member 2 is passed in the vicinity of the intersection of the one side link member 5 and the other side link member 6, thereby restricting the inclination or the like of the pull handle 10 in the horizontal plane. High effect.

  The present invention is not limited to the embodiments described above. The configuration of the lattice material and the link can be changed as appropriate. The guide member 2 only needs to be provided between the one side link member 5 and the other side link member 6 and on the fixing pin 7 that fixes the link 4 to the lattice members 3a and 3b. As shown, the one side link member 5 and the other side link member 6 do not have to intersect at the position of the fixing pin 7. Further, the shape and material of the guide member, the attachment method, and the like can be changed as appropriate. INDUSTRIAL APPLICABILITY The present invention can be applied to all telescopic gates such as a telescopic gate having no rails or casters and a large and wide telescopic gate formed by connecting a plurality of gate main bodies.
