DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for fixing a column and a sheath fitted to the column.

[0002]

2. Description of the Related Art As an outer fence of a house, there is known an outer fence in which panels are provided between columns erected at predetermined intervals. Further, in order to increase the durability and strength of this type of outer fence, there is also known a type using a pultruded aluminum product as a support.

[0003] The use of aluminum pillars for the outer fence has the advantage that the strength can be improved without impairing the lightness of the pillars. The impression that is felt from the appearance of the aluminum skin surface is cold and hard,
The feeling may not be in harmony with the appearance of the house.

[0004] In order to prevent such an impression, a synthetic resin sheath tube is fitted on an aluminum column to cover and hide the skin surface of the column, and only the synthetic resin sheath tube is covered from the outside. In some cases, the construction was made to make the impression received from the exterior warm and soft without impairing the strength of the strut by making it visible. In the case of performing such construction, conventionally, as a means for fixing a synthetic resin sheath tube and an aluminum column covered by the sheath tube, a required number of mounting screws are screwed in from the outside of the sheath tube. There was a method of tightening to a support.

[0005]

However, when the sheath tube is fixed to the column by conventional means, the heads of the mounting screws are exposed to the outside at a plurality of locations on the outer surface of the sheath tube, and these heads stand out. In addition to the fact that the appearance may be unsightly, there is a problem that the strength of the sheath tube is reduced because a screw hole is opened in the sheath tube. In addition, there is a problem in workability that the work of screwing in a required number of mounting screws is troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and problems, and it has been made possible to fix a support post and a sheath cylinder without using a mounting screw, thereby achieving the above-mentioned mounting screw. Not only can there be no room for the head to stand out and make the appearance unsightly, or the screw hole to open in the sheath cylinder, and the pillar has excellent workability when fixing the pillar and the sheath cylinder. An object of the present invention is to provide a fixing structure with a sheath cylinder.

[0007]

According to a first aspect of the present invention, there is provided a fixing structure of a column and a sheath tube, the intermediate member being interposed between the column and the sheath tube fitted to the column, and the column. A locking body, a locked body provided on the intermediate member, which is a counterpart of the locking body, and a pressing portion provided on the intermediate member for pressing the inner surface of the cylindrical wall of the sheath cylinder outward. The locked body can be displaced in the outward direction with respect to the locking body, and can be engaged at an arbitrary relative position in the inward direction. Either one of the locking members is formed of a plurality of projections that are repeatedly continuous in a sawtooth shape, and the other is formed of a claw piece that can ride over any projection in the outward direction and can engage with any projection in the inward direction. That is.

According to a second aspect of the present invention, in the fixing structure of the first aspect, the locking member comprises a plurality of projections which are repeatedly formed in a saw-tooth shape, and the locked member is formed of an outer member. In the direction, it is possible to get over any projection of the locking body, and in the inward direction, it is a claw piece that can engage with any projection of the locking body, and each of the opposing portions of the column is provided with a different functional part. Each of these functional portions is provided with a locking body and a recess inwardly adjacent to the locking body, and the intermediate member includes a pair of arm portions corresponding to each of the pair of functional portions of the column. A locked body that extends from the arms and can be loosely fitted in the recess and a horizontal rod extending between the bases of the pair of arms are integrally provided, and a pressing portion protrudes from the horizontal rod. It is provided.

According to a third aspect of the present invention, there is provided a fixing structure of a column and a sheath tube according to the second aspect, wherein the distal end portion of the arm portion projects in a direction in which the arm portion moves away from the corresponding functional portion of the column. This is a single piece, and the locked body extends from the end of the overhanging piece.

[0010]

According to the first aspect of the present invention, the supporting tube is loosely fitted to the supporting column and the intermediate member is interposed therebetween, and one of the connecting members is connected in a sawtooth shape. The locked body is formed of a plurality of projections, the other being capable of climbing over any sawtooth projection in the outward direction, and being engaged with a hook piece capable of engaging with any sawtooth projection in the inward direction. When displaced outward, the intermediate member approaches the inner surface of the sheath wall of the sheath. Therefore, when the position of the locked body with respect to the locking body is determined by pressing the pressing portion of the intermediate member against the inner surface of the cylindrical wall of the sheath tube, and the locked body is engaged with the locking body in the inward direction, The member is in a state of being stretched between the column and the sheath tube, and the column and the sheath tube are fixed with a force corresponding to the tension force of the intermediate member. When the engagement position of the locked body with respect to the locking body is moved outward, the tension force of the intermediate member increases, and the column and the sheath cylinder are fixed with a larger force. According to the first aspect of the present invention, since the locking body is composed of a plurality of protrusions or claw pieces that are continuous in a saw-tooth shape, in the case of using a drawn aluminum molded body for the supporting column, the locking body is simultaneously formed when the supporting column is formed. Can be provided integrally with the column.

According to the fixing structure of the supporting column and the sheath cylinder according to the second aspect of the invention, the same operation as that described in the first aspect of the invention is exerted. In addition, since the intermediate member has a structure in which a pair of arms and a locked body and a horizontal rod portion having a pressing portion are integrally provided, the locked body is moved outward to individually When the projection is moved over, the arm is deformed, and the movement is easily performed. Furthermore, since the locked member of the intermediate member can be loosely fitted into the recess of the functional portion and the intermediate member can be inserted between the support and the sheath tube, the intermediate member can be inserted between the support and the sheath tube. It can be easily interposed.

According to the fixing structure of the column and the sheath cylinder according to the third aspect of the invention, the same operation as that described in the second aspect of the invention is exerted. In addition, since the locked body is provided at the end of the projecting piece formed by the tip of the arm, the locked body is moved outward to get over the individual projections of the locking body. In this case, not only the arm but also the overhanging piece are deformed, so that the overhang is made easier than in the second aspect of the present invention.
