Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extruded mold material used for various purposes, a hollow rod material such as a pipe, for example,
The present invention relates to an improvement of an end protector of a hollow rod used as a vertical lattice attached to a window opening of a building, a frame of a partition, a constituent material of various fittings, and the like.

[0002]

2. Description of the Related Art As a protector attached to the end portion Pa of a hollow rod P for the purpose of protecting the end portion Pa of the hollow rod P used for various purposes, as shown in FIG. A protector of a type including an insertion portion 302 that is inserted into the hollow rod material P from an end opening Pb of the rod material P and a cap portion 301 that closes the opening of the hollow rod material P is used.

[0003] Such a protector is provided with the cap portion 301.
Is configured as a plate-shaped body having a size that closes the opening of the hollow rod P having a substantially rectangular cross section, and the insertion portion 302 is integrally formed from the cap portion 301 on one surface side of the cap portion 301. The cap portion 301 and the insertion portion 302 are integrally formed using a plastic material so as to be projected.

Further, the insertion portion 302 in such a protector has a central portion 302a through which a hole 302a 'extending from the tip of the insertion portion 302 to the base portion is transparently formed, and radially extends from the central portion 302a. It is provided with four plate-shaped pieces 302b, 302b, etc. whose tips are respectively brought into contact with the inside of the corners of the hollow rod P when the insertion portion 302 is inserted into the hollow rod P.

Further, such a protector is provided with the cap portion 3
01 is provided with a communication hole 301a through a hole 302a ′ that is transparently provided in the central portion 302a of the insertion portion 302, and from the side of the cap portion 301 where the insertion portion 302 does not project. Communication hole 301a
Further, the wedge member 303 having a prismatic shape is inserted into the hole 302a 'provided in the central portion 302a of the insertion portion 302 in a driving shape.

In the wedge member 303, the surfaces 303a, 303a ... In the insertion direction of the cap portion 301 into the communication hole 301a gradually expand outward from one end side of the insertion side to the other end side. The wedge member 303 is configured such that the size of the hole 302a ′ penetrating the insertion portion 302 and the thickness of the wedge member 303 are substantially equal on one end side of the insertion side. And the wedge member 3 is larger than the size of the hole 302a ′ toward the other end side.
The thickness of 03 is gradually increased.

Therefore, according to such a protector, the insertion portion is inserted from the end opening Pb of the hollow rod P into the hollow rod P so that the end opening Pb is closed by the cap portion 301. After inserting 302, the wedge member 303 is attached to the communication hole 301a of the cap portion 301.
And the insertion portion 3 by inserting the insertion portion 302 into the hole 302a ′ of the insertion portion 302 in a driving manner.
02 by pushing the central portion 302a
The four plate-shaped pieces 302 radially projecting from 2a
b, 302b, ... are pressed against the insides of the corners of the hollow rod material P, so that the end opening Pb of the hollow rod material P is closed by the cap portion 301. It can be assembled to the end of P.

[0008]

However, in the conventional protector, when the hollow rod member P is assembled to the end portion Pa, the insertion portion 302 is inserted from the end opening Pb of the hollow rod member P. Since it is necessary to insert the wedge member 303 into the communication hole 301a of the cap portion 301 and the hole 302a ′ of the insertion portion 302 in a driving manner, the end portion Pa of the hollow rod P is assembled with one touch. It was impossible.

Further, the wedge member 303 requires a required force to be driven, and the wedge member 303 has a prismatic shape and the area of one end to which the force is applied is relatively small. It is difficult to apply a sufficient force to the wedge member 303 to drive it, and in order to properly drive the wedge member 303 into the communication hole 301a of the cap portion 301 and the hole 302a ′ of the insertion portion 302. Had to use a tool such as a hammer to hit one end of the wedge member 303.

Further, in such a conventional protector, after the wedge member 303 is driven and assembled to the hollow rod P, the driven wedge member 303 is communicated with the cap portion 301. Since it cannot be extracted again from the hole 301a and the hole 302a 'of the insertion portion 302, even if it is necessary to remove the protective equipment from the end of the hollow rod P, the removal is not performed simply. It was something I couldn't get.

Therefore, the main object of the present invention is to eliminate the disadvantages of the prior art.

Another object of the present invention is to provide an end protector for the hollow rod which can be easily and easily assembled to the open end of the hollow rod.

Further, the hollow rod can be assembled to the open end of the hollow rod without using a special tool. Further, after the hollow rod is assembled to the open end of the hollow rod, the open end can be removed from the open end. It is an object of the present invention to provide an end protector for the hollow rod, which can be relatively easily removed when it becomes necessary to remove it.

The end protector H of the hollow rod material P according to the present invention includes a cap portion 10 for closing the end opening Pb of the hollow rod material P such as an extrusion mold material or a pipe, and the cap portion 10.
And a plug-in portion 20 that is inserted from the end opening Pb of the hollow rod member P into the hollow rod member P, and the plug-in portion 20 is the plug-in portion 2.
Since the elastic engaging piece 21 that extends laterally from 0 is provided, the insertion portion 20 is provided until the end opening Pb of the hollow rod P is closed by the cap portion 10.
Is inserted into the inside of the hollow rod P through the end opening Pb of the hollow rod P, so that the elastic engaging piece 21 is pressed against and abuts on the inner wall surface Pc of the hollow rod P. The elastic engaging piece 21 can be elastically deformed, and the insertion portion 20 is pulled out from the inside of the hollow rod portion by the engagement between the elastic engaging piece 21 and the inner wall surface Pc of the hollow rod member P in the elastically deformed state. It is possible to assemble the hollow rod member P into the end opening Pb of the hollow rod P with one touch and easily so that the end portion opening Pb is kept closed by the cap portion 10.

Since the cap portion 10 has a size that covers the end opening Pb of the hollow rod P,
With the cap portion 10, the opening end portion Pa of the hollow rod material P can be reliably protected and / or makeup is applied.
By using the surface of the cap portion 10 on the side where the insertion portion 20 is not provided, the insertion portion 20
It is possible to easily and reliably insert the insertion portion 20 so that the insertion portion 20 can be sufficiently inserted into the hollow rod member P without using a special tool.

Further, when it becomes necessary to remove the end protector H assembled in the end opening Pb of the hollow rod P, the cap portion 10 is gripped and the insertion portion 20 is closed. It is possible to pull out from the inside of the rod material P to perform such removal, and such removal can be relatively simple. Further, since the elastic engaging piece 21 provided on the insertion portion 20 is elastically restored by such removal, the removed end protector H can be reused without any particular trouble.
