Description

[Detailed description of the invention] Industrial application field This invention relates to a lattice frame for a telescoping gate, and can improve the durability and beauty of a gate having a pantograph telescoping mechanism.

PRIOR TECHNOLOGY The lattice frame of this type of gate has been made of aluminum profiles with a blind cap made of synthetic resin on the top. There are problems such as premature discoloration of the cap due to deterioration by ultraviolet rays, so to avoid this problem, proposals have been made to fold the mold material integrally and omit the synthetic resin cap. (For example, Jikko 56-
No. 41040, JP-A-58-97442, U.S. Pat. No. 58-83588
Problems that the invention attempts to solve However, in all of these prior art techniques, the shape material is plastically deformed into a state close to a U-shape with a horizontal portion at the top. Therefore, the surface part that is bent undergoes significant elongation, and when an alumite film is formed on the surface, such as with aluminum shapes, the alumite film becomes thin and uneven in color with other parts, resulting in beautiful alumite coloring. It was difficult to express them uniformly. In particular, considerable strength is required for the fixed columns and doorstop columns on both the left and right sides of the door body, and U-shaped or hollow rectangular aluminum sections with the front and rear walls separated are used. For such a grid frame,
It was extremely difficult to hide the eyes by any means other than fitting a synthetic resin cap.

Measures to Solve the Problems In view of the above circumstances, the inventor of the present invention has conducted extensive studies to improve the durability and aesthetics of lattice frames such as fixed posts for retractable gates and door stop posts.
Engagement grooves 4, 4 and 4', 4' are provided at both side ends of the front wall 2 and rear wall 3 of the substantially U-shaped or hollow rectangular column 1 with the front wall 2 and rear wall 3 separated from each other. are provided at the upper opening end of the column 1, and left and right side walls 6, 6,
A connecting auxiliary member 5 having a semi-cylindrical shape is placed thereon, and a draining member 7 having upward locking edges 8, 8 formed at both left and right ends is engaged with both side walls 6, 6 of the connecting auxiliary member.
A plate-shaped main body part 10 and inwardly bent edges 11, 1 on both sides thereof.
The inwardly bent edges 11, 11 of the middle part of the covering member 9 provided opposite to each other are cut off, and the plate-shaped main body part 10 of the covering member 9 is curved into a semi-cylindrical shape. 7, and the front and rear parts of the covering member 9 are inserted into the engaging grooves 4, 4 and 4', 4' of the column body 1.
By fitting the inwardly bent edges 11, 11 of the two, the intended purpose is achieved.

In carrying out this project, the columns, auxiliary connection members, and covering members are made of aluminum extrusion or pultrusion molding, and the slide pins of the pantograph expansion and contraction mechanism 12 are moved vertically as a lattice frame. Guide groove 13 to operate
In the case of using a U-shaped columnar body, a downward protrusion 14 is formed at the bottom of the connection auxiliary member 5 and is fitted into the guide groove 13, and as shown in FIGS. 5 and 6. When using a hollow rectangular column as described above, downward protrusions 15, 15 are formed at positions slightly inward from both ends of the connection auxiliary member 5, and these are engaged with the side walls of the hollow rectangular column 1. The column 1 and the connection auxiliary member 5 should be fitted together.

In implementing the present invention, the draining member 7 can be made by molding relatively inexpensive synthetic resin, hard rubber, etc., and its both ends are made as thin as possible, and the side walls 6, 6 of the connecting auxiliary member 5 are made as thin as possible. It is preferable to have engagement grooves 16, 16 formed at the lower ends that come into contact with each other.

The proposed lattice frame has the engagement grooves 4, 4 and 4' of the column 1,
4', the front and rear inner bent edges 1 of the covering member 9;
Although it is possible to integrate the column 1 and the covering member 9 by fitting the columns 1 and 11, if necessary, the overlapping portion of the column and the covering member may be caulked or riveted to further firmly fix the column and the covering member. I can do it. Further, in the case of a lattice frame to which the fixing pin 17 of the pantograph expansion/contraction mechanism 12 is attached, by passing the fixing pin 17 through the overlapping portion of the column 1 and the covering member 9, the two can be integrated.

Effect According to the present invention, the connection auxiliary member 5 with the side walls 6, 6 shaped like a semicircle is placed in the upper end opening of the U-shaped or hollow rectangular column 1, and the connecting auxiliary member 5 is placed in the upper end opening of the U-shaped or hollow rectangular column 1. Inwardly bent edges 11, 11 of the contacting middle part
is cut off and only the plate-like main body 10 is deformed into a semi-cylindrical shape, so the curvature at the bending part of the covering member 9 is extremely large, and the elongation of the member surface during bending is substantially eliminated. It does not cause troubles such as color unevenness on the surface coating film, and a draining member 7 having upward locking edges 8, 8 formed at both ends is interposed between the connecting auxiliary member 5 and the covering member 9, Since the covering member 9 is engaged between the upward locking edges 8, 8, rainwater does not enter into the lattice frame, and the upward locking edges 8, 8 of the drainage member are connected to the inwardly bent edges 11, 11. The cuts of the plate-shaped main body 10 that have been removed are hidden to prevent deterioration of the aesthetic appearance, and the connecting auxiliary member 5 and the covering member 9 are provided on the top of the lattice frame.
is exposed, and the side edges of the drainage member 7 made of synthetic resin or the like are only slightly exposed, so that the phenomenon of UV deterioration of the member made of synthetic resin or the like is almost non-existent.

Effects of the invention According to the lattice frame of the present invention, engaging grooves 4, 4 and 4', 4' are provided at each side end of the front wall 2 and rear wall 3 of the U-shaped or hollow rectangular column 1, The connecting auxiliary member 5 and the draining member 7 are placed and engaged with the upper open end of the column, and the covering member 9 is bent into a curved shape.
Since the inwardly bent edges 11, 11 of the column 1 are fitted into the engagement grooves of the column 1, the open end of the thick column can be protected with the same aluminum material as the column 1. , the durability and aesthetics of the lattice frame of the telescopic gate can be dramatically improved.
