JP5303353B2 - Structure for preventing the end of a long member from being attached to a long frame material - Google Patents

Description

The present invention relates to a structure for preventing an end portion of a long member attached to a long frame member, and typically, the long member is air tight (airtight material).

In order to maintain airtightness when the opening is fully closed, air tight may be provided between the door body and the opening frame. The air tight is typically a long rubber member, and is inserted into a pocket of a frame material provided on the opening frame side or the door body side.

Since air tight can move in the length direction in the pocket of the frame material, air tight moves in the pocket due to friction at the time of contact with the door body or part from the pocket end unless it is provided with any retaining means There is a risk of accidental exit.

Conventionally, the air tight is prevented from coming off by fixing a stopper made of a resin block to the pocket end using a screw. FIG. 8 is a view showing the above prior art, in which an air tight 8 ′ is inserted into a pocket of a vertical frame 7 ′ provided on an end face of a door body 6 ′, and a stopper 9 ′ is fixed using screws at upper and lower ends of the pocket. By doing so, the air tight 8 'is prevented from coming off. Patent Document 1 also discloses a similar retaining structure.

However, in the case where the stopper is fixed to the end of the pocket as shown in FIG. 8, there is a drawback that the air tight does not enter the pocket end (the air tightness at the pocket end decreases) and a fastening part for fixing is required. There is a problem of becoming.

There is also a method of adhering air tight in the pocket, but in this case, there is a drawback that it is difficult to replace air tight, which is a consumable item that deteriorates over time.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view of the sliding door device when the door body is fully closed, and a door frame side half of a rectangular frame comprising an upper frame 1, a lower frame 2, a door end side vertical frame 3, and a door bottom side vertical frame 4. The sleeve panel 5 is provided in the part, and an opening is formed between the door-end side vertical frame 3 and the door-end-side end of the sleeve panel 5, and the door body 6 serves as the opening width direction of the opening. Open and close by moving to. As shown in FIG. 2, a suspension rail 1A extending in the opening width direction is provided in the upper space of the upper frame 1, and the guide roller 6A at the upper end of the door body 6 rolls on the suspension rail 1A. By doing so, the door body 6 moves in the left-right direction.

A horizontal frame 7 extending in the horizontal direction along the upper frame 1 is provided on the door frame side half of the upper frame 1. An air tight 8 is attached to the horizontal frame 7, and an upper end portion of the indoor-side finding surface 60 of the door body 6 comes into contact with and slides on the air tight 8. The horizontal frame 7 may be integrally formed with the upper frame 1. In the illustrated example, the horizontal frame 7 is connected to the upper frame 1 using screws 7A, but the horizontal frame may be integrally formed from the same member as the upper frame.

The horizontal frame 7 is a long member having substantially the same length as the width dimension of the door body 6, and has an L shape in sectional view from a horizontal piece 70 and a vertical piece 71 as shown in FIG. 4. A pocket 72 extending over the entire length of the horizontal frame 7 is formed at the tip of the horizontal piece 70. The air tight 8 is detachably attached to the pocket 72.

The pocket 72 connects two pieces that are spaced apart from each other, that is, the lower piece 73 (formed from the front end side portion of the horizontal piece 70) and the upper piece 74, and the base ends of the lower piece 73 and the upper piece 74. And a bottom piece 75. Further, bent pieces 730 and 740 are formed at the distal ends of the lower piece 73 and the upper piece 74, respectively, and an opening 76 extending in the length direction is formed between the bent pieces 730 and 740. A locking hole 77 is formed in the bottom piece 75 at a portion close to the end of the door butt. The way of calling the two opposing pieces constituting the pocket 72 differs depending on the posture of the frame material in which the pocket is provided. For example, in the posture shown in FIG. 7, it may be referred to as opposed side pieces instead of the opposed upper and lower pieces. it can.

The air tight 8 is a long member having substantially the same length as the pocket 72 and is typically formed from rubber. The air tight 8 has a cross-sectional shape from a base piece 80 and an inclined contact piece 81 extending obliquely upward with respect to the base piece 80, and a pocket 72 is formed on the back surface of the base piece 80. An insertion portion 82 to be inserted into the inside protrudes. In a state where the insertion part 82 is inserted into the pocket 72, the back surface of the base piece 80 is in contact with the bent pieces 730 and 740 (see FIG. 6).

The insertion portion 82 can slide in the pocket 72 in the length direction and has a width dimension larger than the width of the opening 76, thereby preventing the insertion portion 82 from easily coming out of the opening 76. On the other hand, when the air tight 8 is removed and replaced, the insertion portion 82 can be extracted through the opening 76 by elastically deforming the insertion portion 82.

The door end side end of the horizontal frame 7 is in contact with the door end side vertical frame 3, and the door end side end of the airtight 8 attached to the pocket 72 of the horizontal frame 7 is the door of the horizontal frame 7. It does not come out from the front end. By using the stopper 9 at the door butt side end of the air tight 8, the horizontal frame 7 is prevented from coming out from the door butt side end.

The stopper 9 includes a base 90, a locking piece 91 bent at the tip of the base 90, a rising piece 92 bent at the base end of the base 90 in a direction opposite to the bending direction of the locking piece 91, Consists of. In the illustrated embodiment, the width dimension of each portion is such that the width of the rising piece 92> the width of the base 90> the width of the locking piece 91.

The base 90 is a thin plate-like portion having a second surface portion 90B opposite to the first surface portion 90A, and has a width dimension that can be inserted into the pocket 72 from the door butt side end portion of the horizontal frame 7. , And extends along the inner surface of the bottom piece 75 in which the locking hole 77 is formed. The first surface portion 90 </ b> A faces the inner surface of the bottom piece 75. The width of the base 90 is slightly smaller than the dimension between the inner surfaces of the opposing side pieces 73 and 74, that is, the width dimension of the inner surface of the bottom piece 75. The length of the base 90 is substantially the same as the distance from the door butt side end of the horizontal frame 7 to the locking hole 77 formed in the bottom piece 75. That is, the base 90 has a length dimension such that the rising piece 92 abuts against the door butt side end portion of the horizontal frame 7 in a state where the locking piece 91 is locked in the locking hole 77.

The rising piece 92 has a height and a width so as to block the end portion of the pocket 72, and the rising piece 92 is engaged with the locking hole 77 and the rising piece 92 is in the horizontal frame 7 and the air tight. 8 is brought into contact with the end of the door butt from the outside to close the end of the pocket 72 on the door butt. Here, the rising piece 92 does not necessarily need to completely close the end portion on the door bottom side of the pocket 72, as long as it functions as a stopper that contacts the end portion of the air tight 8 and prevents the end portion from coming off. The pocket 72 may be partially blocked.

As shown in FIG. 6, the stopper 9 has the locking piece 91 locked in the locking hole 77 of the bottom piece 75 of the pocket 72, and the rising piece 92 abuts the longitudinal end of the air tight 8. In the state where the end in the length direction is closed, the insertion portion 82 of the air tight 8 is inserted into the space in the pocket 72 opposite to the inner wall of the pocket (bottom piece 75) with respect to the base 90, that is, the space on the second surface portion 90B side. And the movement of the base 90 in the direction away from the pocket inner wall (bottom piece 75) is restricted by the insertion portion 82. In a range where the locking state between the locking piece 91 and the locking hole 77 is maintained, the base 90 is allowed to move so far as to be separated from the bottom piece 75. The base 90 may be lightly pressed by the insertion portion 82 of the air tight 8 to such an extent that the bottom piece 75 is not loose. Therefore, the movement of the stopper 9 in the direction away from the door butt side end of the horizontal frame 7 is restricted by the locking piece 91 of the stopper 9 being locked in the locking hole 77 of the bottom piece 75 of the pocket 72. The movement in the direction in which the piece 91 is detached from the locking hole 77 is restricted by the insertion portion 82 of the air tight 8 located in the pocket 72, and the rising piece 92 of the stopper 9 serves as a retaining piece at the end of the air tight 8. Function.

A procedure for mounting the stopper 9 will be described with reference to FIG. A state in which the door tail side end portion of the air tight 8 is slid and moved beyond the locking hole 77 in a direction away from the door bottom side end portion of the pocket 72, or the door tail side portion of the insertion portion 82 of the air tight 8 is partially The stopper 9 is inserted into the pocket 72 from the door butt side end portion of the pocket 72 while being pulled out from the opening 76, and the locking piece 91 on the tip side of the stopper 9 is locked in the locking hole 77. At this time, the rising piece 92 on the base end side of the stopper 9 abuts on the door butt side end portion of the horizontal frame 7 (pocket 72) from the outside.

Next, the insertion portion 82 of the air tight 8 located in the pocket 72 is moved to the door-end side end portion, or the inserted insertion portion 82 of the extracted air tight 8 is inserted into the pocket 72 from the opening 76, The insertion portion 82 is positioned in a space opposite to the pocket inner wall (bottom piece 75) with respect to the base 90, and the insertion portion 82 restricts the movement of the base 9 away from the pocket inner wall (bottom piece 75). The door butt side end of (insertion portion 82) is brought into contact with the rising piece 92 of the stopper 9.

Thus, in order to provide the retaining structure according to the present embodiment, the stopper 9 is inserted into the pocket 72 from the door butt side end of the pocket 72, and the locking piece 91 is locked in the locking hole 77, Since it is only necessary to slide the end of the air tight 8 to the door end of the pocket 72, the number of parts is smaller than when the stopper is fixed using screws or the like, and the stopper 9 is attached. The work is also easy. In addition, the stopper 9 is prepared, and a locking hole 77 is formed in a predetermined portion of the bottom piece 75 (a position where the locking piece 91 of the stopper 9 inserted into the pocket 72 is locked). A retaining structure can be retrofitted.

In the embodiment, the mounting of the air tight 8 on the horizontal frame 7 provided on the upper frame 1 of the opening frame has been described. However, the end structure of the air tight mounted on the long frame member according to the present invention is provided on the opening frame side. It is understood by those skilled in the art that it can be applied to an air tight end retaining structure attached to a vertical frame provided on the door, or an air tight end retaining structure attached to a horizontal frame or vertical frame provided on the door body side. Is done.

The present invention can be used for an air tight end retaining structure attached to a long frame material.
