Description

  In the present invention, an end surface is an open surface, a groove is formed along the longitudinal direction, and a cross-sectional shape on the end side is substantially C-shaped, and is inserted from the open surface of the mall body, An end cap that closes the open surface, and the end cap includes a cap end portion that closes the open surface, and a molding insertion portion that is connected to the cap end portion and is inserted from the open surface of the molding body. Related to the mall.

Conventionally, the molding main body having a substantially C-shaped cross section and the end cap for closing the open surface of the end surface of the molding main body are attached by an adhesive or caulking.
However, since the adhesive protrudes or the end cap comes off due to a caulking defect, an attachment structure as shown in FIG. 14 has been proposed.

  In the figure, an end surface of the molding body 1 is an open surface 3, a groove 5 is formed along the longitudinal direction, and a cross-sectional shape on the end side is substantially C-shaped. The end cap 7 includes a cap end portion 9 that closes the open surface 3, and a molding insertion portion 11 that is connected to the cap end portion 9 and is inserted from the open surface 3 of the molding body 1.

  The end side of the molding main body 1 and the molding insertion portion 11 of the end cap 7 are provided with end cap insertion direction pulling means for pressing the cap end portion 9 of the end cap 7 against the end surface of the molding body 1. ing.

  This insertion direction pull-in means is provided in the molding body 1 and has a hole 17 having a surface 15 intersecting with the insertion direction of the end cap 7, and provided in the end cap 7. It consists of a protrusion 21 having a slope 19 that generates a pulling force in the insertion direction (the direction of arrow J in the figure).

  In the configuration shown in FIG. 14, when the cap end 9 of the end cap 7 comes into contact with the end surface of the molding body 1, the inclined surface 19 of the projection 21 of the end cap 7 causes the surface 15 of the hole 17 of the molding body 1 to It is set so that it may contact.

The end cap 7 is made of resin and is elastically deformed so that the surface 15 and the inclined surface 19 are pressed against each other.
According to such a configuration, when the end cap 7 is inserted into the molding body 1 and the cap end portion 9 of the end cap 7 abuts against the end surface of the molding body 1, the slope 19 of the protrusion 21 of the molding insertion portion 11 is formed. A force that pulls the end cap 7 in the insertion direction (in the direction of the arrow J in the figure) is generated on the inclined surface 19 so as to press against the surface 15 of the hole 17 of the molding body 1, and the cap end 9 of the end cap 7 is the molding body. 1 is pressed against the end face (see Patent Document 1).

  The end cap 37 is a resin molded product, and includes a cap end portion 51 that closes the open surface of the molding body 35, and a molding insertion portion 53 that is connected to the cap end portion 51 and is inserted from the opening surface of the molding body 35. .

The molding insertion portion 53 is bent from the inner insertion portion 53a and the inner insertion portion 53a inserted into the space surrounded by the inner side portion 39a ′, the upper portion 39b, and the outer side portion 39c of the base body 39 of the molding body 35, Both the outer insertion portion 53b facing the outer surface of the inner side portion 35a ′ of the main body 35 and the lower end of the inner side portion 35a ′ of the molding main body 35 so as to bridge the inner insertion portion 53a and the outer insertion portion 53b. And a bridging portion 53c connected to the.
(End cap insertion direction pull-in means)
The end cap insertion direction pull-in means for pressing the cap end portion 51 of the end cap 37 against the end surface of the molding body 35 will be described.

  As shown in FIG. 5, the bridging portion 53 c of the molding insertion portion 53 of the end cap 37 is provided with a first hole 61 and a second hole 65 adjacent to the first hole 61. Between the 1st hole 61 and the 2nd hole 65, the 1st surface part 67 which has the 1st surface 67a which cross | intersects the insertion direction (arrow S direction in each figure) of the end cap 37 is formed. Since the end cap 37 is made of resin, the first surface portion 67 has elasticity.

  On the other hand, as described above, the protrusion 52 is formed on the molding body 35 as shown in FIG. When the molding insertion portion 53 of the end cap 37 is inserted from the open surface of the molding main body 35, the projection 52 engages with the first hole 61.

The inclined surface 52a of the protruding portion 52 is set to an inclined surface (reverse inclined surface) that generates a force in a direction to bring the proximal end side of the protruding portion 52 and the first surface portion 67 closer to each other when pressed.
When the cap end portion 51 of the end cap 37 abuts against the end surface of the molding body 35, the slope 52 a of the projection 52 is dimensioned so as to be surely pushed by the first surface 67 a of the first surface portion 67. .

  According to such a configuration, when the molding insertion portion 53 of the end cap 37 is inserted from the open surface of the molding main body 35, the inclined surface 52a of the projection 52 presses the first surface 67a, and the first surface portion 67 is elastically deformed, The first surface 67a is pushed by the elastic repulsive force. Then, a force in a direction to bring the proximal end side of the protrusion 52 and the first surface portion 67 closer to each other is generated, and a force that is pulled in the insertion direction acts on the end cap 37.

In the above embodiment, the protrusion 52 is provided on the molding body 35 and the first surface 67 is provided on the end cap 37. Conversely, the protrusion is provided on the end cap 37 and the first surface is provided on the molding body 35. It may be provided.
(End cap groove direction movement prohibition means)
Next, the end cap groove direction movement prohibiting means for prohibiting the molding insertion portion 53 of the end cap 37 from moving toward the groove 40 of the molding main body 35 will be described with reference to FIG.

A second surface 71 that is not orthogonal to the opening surface of the groove 40 of the molding body 35 is formed on the protrusion 52 of the molding body 35.
The outer insertion portion 53 b above the first hole 61 of the molding insertion portion 53 of the end cap 37 abuts against the second surface 71, and the molding insertion portion 53 of the end cap 37 extends in the opening direction of the groove 40 of the molding main body 35. A third surface 73 that prohibits movement is formed.

According to such a configuration, the third surface 73 of the end cap 37 abuts on the second surface 71 of the molding main body 35, so that the molding insertion portion 53 of the end cap 37 moves in the opening direction of the groove 40 of the molding main body 35. It is prohibited to move.
(End cap retaining means)
Next, an end cap retaining means for prohibiting movement of the end cap 37 in the direction opposite to the insertion direction of the end cap 37 into the molding body 35 will be described with reference to FIG.

  On the back surface of the cap end portion 51 of the end cap 37, a rod portion 81 is formed that is inserted from the open surface of the molding body 35 into the space surrounded by the inner side portion 39a ′, the upper portion 39b, and the outer side portion 39c of the base body 39. (See FIG. 5). A protrusion 83 is formed on the bar portion 81.

A protrusion biting portion 85 is formed at the lower part of the inner side portion 39a of the molding body 35 by injection molding of a resin capable of biting the protrusion 83 (see FIG. 13).
The protrusion 83 has a bar shape that allows the end cap 37 to be inserted into the molding body 35 and prohibits the end cap 37 from being detached from the molding body 35.

  According to such a configuration, by providing the end cap retaining means as the end cap retaining means for prohibiting the movement of the end cap 37 in the direction opposite to the direction in which the end cap 37 is inserted into the molding body 35, the end cap 37 is secured to the molding. The separation from the end face of the main body 35 can be prevented. So-called opening of the mall terminal can be prevented.

  In the above embodiment, the protrusion 83 is provided on the end cap 37 and the protrusion biting portion 85 is provided on the molding body 35. Conversely, the protrusion may be provided on the molding body 35 and the projection biting portion 85 may be provided on the end cap 37. Good.
