[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic gate which expands and contracts in a finding direction by a telescopic link formed by connecting a large number of X-links, and more particularly to a grid frame of a telescopic gate which supports the telescopic link and has casters. It is.

[0002]

2. Description of the Related Art Conventionally, as a lattice frame of this kind of telescopic gate, for example, a lattice frame described in Japanese Utility Model Laid-Open No. 1-109598 is known. This lattice frame is provided in parallel with each other, a pair of vertical frames that support the telescopic link on the inside, a connecting frame attached between the lower ends of the pair of vertical frames, and a lower side of both outer ends of the connecting frame. And casters. Each vertical frame is attached at right angles to the upper surface of the connection frame by an L-shaped bracket provided on the upper surface of the connection frame, while the caster has its bolt portion inserted in a long hole formed in the connection frame. It is attached to the connecting frame by a nut screwed from the connector frame. The connection frame is made of a thick metal plate.

[0003]

As described above, in the conventional grid frame of the telescopic gate, the connection frame to which the load is most applied is formed of a plate material, and is used in a sideways position which is most vulnerable to bending load. Since the holes and the like were formed, the connecting frame was weak in strength. For this reason, the connecting frame is likely to bend, which causes problems such as hindering smooth running of the casters. However, if you increase the thickness of the connecting frame,
Although such a problem is solved, the weight of the lattice frame is increased, and a large force is required for the expansion and contraction operation of the expansion gate. In addition, since an L-shaped fitting is used to attach the vertical frame to the connection frame, there is a problem that the assembling work is troublesome.

[0004] It is an object of the present invention to provide a lattice frame of a telescopic gate capable of simultaneously increasing the strength of the connection frame and the ease of assembly.

[0005]

The lattice frame of the telescopic gate of the present invention is mounted between a pair of vertical frames which are arranged in parallel to each other and support the telescopic link on the inside, and the lower ends of the pair of vertical frames. It has a connecting frame and casters attached to the lower side of both outer ends of the connecting frame, and each vertical frame has an inward-facing cup in the space inside its cross section.
A pair of vertical frames is screwed on the upper surface of the connecting frame, extending in the longitudinal direction of the connecting frame, and with both outer ends inserted into each swallowing groove. The mounting piece to be protruded,
The mounting piece has screw holes for screwing and is shared with the connection frame.
The integrally formed with profiles, the end surface of the mounting piece is perpendicularly formed on the upper surface of the connecting frame, against the upper surface of the connecting frame against the vertical frame
It is characterized by being in contact with the inner surface of the rear wall .

According to this structure, since the mounting piece projecting from the upper surface of the connecting frame extends in the longitudinal direction of the connecting frame, the cross-sectional shape of the connecting frame and the mounting piece becomes vertically long, and its weight is reduced. Bending strength can be increased in comparison with the above. In addition, since the vertical frame comes into contact with the end surface of the mounting piece formed at a right angle to the upper surface of the connection frame and is screwed, the vertical frame is accurately and firmly mounted at a right angle to the connection frame. further,
The vertical frame touches the mounting piece with the upper surface of the connection frame as a guide,
Since it is attached by screwing, the assembling work can be performed easily and quickly.

In the lattice frame of the telescopic gate according to the first aspect, fore ends caps are respectively attached to both ends of the connection frame, and each fore end cap extends to the position of the lower end of each vertical frame. It is preferable that each vertical frame is jointly fastened by screws for attaching to the mounting pieces.

According to this configuration, the fore cap can be firmly attached so as not to be easily detached from the connecting frame, and a dedicated screw for attaching the fore cap can be omitted. Further, the fixing of the fore cap and the fixing of the vertical frame can be performed by the same operation.

As described above, the knob 6 is provided on the support plate 72.
By forming the V-groove 75 with which the engaging portion 2 engages, the knob portion 62 does not fall into the gap 74 of the guide portion 73 in response to vibration caused by opening and closing of the telescopic gate 1. That is, when opening and closing the telescopic gate 1, the lock 15a does not come off and the lower end does not hinder the ground.

As described above, according to the grid frame 12 with casters of the present embodiment, the support frame 41 is
Since the support frame 41 and the attachment piece 44 projecting from the upper surface of the support frame main body 42 are integrally formed, the support frame 41 can have a relatively small cross-sectional shape and a structure resistant to bending loads.
In addition, since the screw hole 45 is formed in the mounting piece 44 and the end surface of the mounting piece 44 extends at right angles to the upper surface of the support frame main body 42, the vertical frame portion 34 is precisely aligned with the support frame 41 at right angles. Good and easy to install.

On the other hand, since the small cap 47 is fastened together with the mounting screw 46 for attaching the vertical frame portion 34 to the support frame 41, the dedicated screw for the small cap 47 can be saved, and the assembling can be performed. The process can be simplified. Moreover, since the caster mounting female screw 52a is fixedly positioned by using the mounting of the small cap 47, the caster 14 can be easily mounted without exposing the female screw 52a to the outside.

In the above-described embodiment, the support frame main body and the mounting piece are formed integrally with each other with a shape, but they may be separately fixed to each other.
