[0008]

[Action]

 According to the end structure of the resin-made hollow extruding member according to any one of claims 1 to 4, the lid is attached to the hollow extruding member, and the protrusion formed on the inner surface of the lid is provided on the rib end of the hollow extruding member. It can be fixed by a simple operation of abutting and ultrasonic welding, and can be fixed with sufficient strength.

Further, according to the invention of claim 4, the ridges of the lid body are divided in the longitudinal direction, and the adjacent ridges are deviated from the coaxial line. Even when the rib of the hollow extruded member is thicker than the thickness of the rib or the rib 4 is displaced due to a dimensional error, the ribs 4 can surely contact and weld.

【Example】

 A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an end structure of the present invention, which is composed of a hollow resin extruded member 1 and a lid 2. As shown in FIG. 2, the hollow extrusion member 1 is a hollow body composed of a pair of parallel flat plates 3 and a plurality of reinforcing ribs 4 connecting the flat plates 3 at a predetermined interval. It is open, and a hollow portion 5 is formed by a pair of flat plates 3 and ribs 4.

On the other hand, as shown in FIGS. 3 and 4, the lid body 2 has a side plate 6 and a protrusion 7 parallel to the rib 4 of the hollow extrusion member 1 on the inner surface of the side plate 6. It is configured such that it is formed in the abutting portion. In addition, the inner surface of the side plate 6 may be provided with a protruding portion 8 that is inserted into the hollow portion 5 of the hollow extruding member 1 and positioned, and the number of the protruding portions 8 may be any number, and the shape may be any shape. Good.

Then, the lid 2 is attached to the open end of the hollow extruded member 1 to hide the entire open end. In this state, the ribs 7 of the lid 2 are brought into contact with the ends of the ribs 4 of the hollow extruded member 1 and fixed by ultrasonic welding.

Further, as shown in FIG. 5 as a second embodiment, the lid body 2 includes a side plate 6 and a protrusion 7 parallel to the rib 4 of the hollow extruded member 1 on the inner surface of the side plate 6. A plurality of ribs 4 are formed in parallel with each other in contact with the ribs 4, and the distance between the ribs 7 is narrower than the thickness of the ribs 4. Then, the lid 2 is attached to the open end of the hollow extruding member 1 similar to that of the first embodiment, and the ridge 7 of the lid 2 is brought into contact with the end of the rib 4 of the hollow extruding member 1 for ultrasonic welding. Be fixed by that.

Further, as shown in FIG. 6 as a third embodiment, the lid body 2 has a side plate 6 and a protrusion 7 parallel to the rib 4 of the hollow extruded member 1 on the inner surface of the side plate 6. The ribs 4 are configured to be divided in the longitudinal direction into a multi-stage portion at which the ribs 4 come into contact, and the ridges 7 may be formed in one line or in parallel. Then, as in the first embodiment, the lid 2 is attached to the open end of the hollow pushing member 1 and fixed by ultrasonic welding.

Further, as shown in FIG. 7 as a fourth embodiment, the lid 2 has a side plate 6 and a protrusion 7 parallel to the rib 4 of the hollow extruded member 1 on the inner surface of the side plate 6. The ribs 4 are divided in the longitudinal direction into abutting portions, and the adjacent ridges 7 are arranged so as to deviate from the coaxial line. The ridges 7 may be formed in one line or in parallel. Good. Then, as in the first embodiment, the lid 2 is attached to the open end of the hollow extruded member 1 and fixed by ultrasonic welding. In the ridges 7 formed in this way, even when the distance between the ridges 7 is wider than the thickness of the ribs 4 of the hollow extruded member 1 or when the ribs 4 are displaced due to dimensional error, the gap between the ridges 7 becomes large. Since the rib 4 is prevented from falling, the rib 7 can be reliably brought into contact with the rib 7.

[0016]

[Effect of device]

 As described above, according to the end structure of the resin-made hollow extruded member of the present invention, the protrusion formed on the inner surface of the lid comes into contact with the rib end of the hollow extruded member and is ultrasonically welded. It can be firmly fixed with simple work. Furthermore, by dividing the protrusion formed on the inner surface of the lid in the longitudinal direction and forming adjacent protrusions so as to deviate from the coaxial line, the distance between the protrusions is wider than the thickness of the rib of the hollow extruded member. In some cases, even if the ribs are displaced due to dimensional error or the like, the ribs do not fall into the gap between the ribs, and the ribs can be reliably brought into contact with each other.
