Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a door for preventing rattling by keeping a constant gap between an outer frame fixed to a building and a door incorporated in the outer frame. For spacers.

[Conventional technology]

As shown in FIG. 2, a door of a building, such as a unit bath, is transported by mounting a door 2 inside an outer frame 1 fixed to the building and attaching the door 2 by a hinge 3 so that the door can be opened and closed. It is offered for sale.

By the way, since the door 2 is mounted in the outer frame 1 so as to be openable and closable, there is a gap between the outer periphery of the door 2 and the inner periphery of the outer frame 1, and the above-mentioned gap is present in the door 2 during transportation. It may cause rattling.

For this reason, conventionally, there has been adopted a means for preventing the rattling of the door 2 by interposing a piece of wood in the gap between the door 2 and the outer frame 1 and fixing it with an adhesive tape.

[Problems to be solved by the device]

However, the gap generated between the door 2 and the outer frame 1 is not constant, and thus it is troublesome to prevent rattling by a piece of wood and to secure a piece of wood with a thickness and width corresponding to the gap, and to secure the piece of wood with adhesive tape. Since it is attached and fixed, there is a problem that workability is poor.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is to provide a door spacer that can deal with a change in gap with a single structure and can be easily attached.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention uses an outer surface, which is contradictory to the opening of a tubular flexible portion, which is partly cut away, as a contact surface, and sandwiches this opening on both side opening edges of the tubular flexible portion. In this configuration, plate portions extending in opposite directions are connected to each other, and side walls that bend toward the same side as the tubular flexible portion are provided at the end edges of both plate portions.

[Action]

The cylindrical flexible part located in the center allows the space between the side walls to be elastically changed, and when fitted into the outer peripheral groove of the door for mounting, it can accommodate a wide range of groove width changes and the cylindrical shape. The contact surface of the flexible portion and the plate portions on both sides maintain a constant gap between the door and the outer frame, and prevent rattling of the door.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the door 2 is incorporated in the outer frame 1 and is attached by a hinge 3 so as to be openable and closable.

As shown in FIG. 2 and FIG. 3, this door 2 uses a mold member 7 having a cross-sectional shape in which an inner panel support wall 5 and an outer panel support wall 6 are provided on both sides of a substrate 4, and four mold members 7 are used. Are joined together by a corner joint 8 to assemble a door frame 9, and panels 10 and 10 are stretched on both sides of the door frame 9, and the door frame 9 is formed with a groove 11 on the outer periphery by the outer panel support walls 6 and 6. Are formed.

As shown in FIGS. 1 and 2, the spacer 21 fitted in the groove 11 and interposed in the gap between the door 2 and the outer frame 1 is made of a hard synthetic resin, and a part thereof is cut away. A cross-sectional shape in which plate portions 24, 24 extending in opposite directions with the opening 23 sandwiched between the plate-shaped flexible portions 22 are formed on both sides of the opening-shaped flexible portion 22, and side walls 25, 25 are provided at the end edges of the plate portions 24, 24. Is formed in.

The cylindrical flexible portion 22 of the spacer 21 is formed in a cylindrical shape, and the outer surface opposite to the opening 23 is a contact surface 26 against the door frame 9.

The plate portions 24, 24 on both sides are arcuate curved surfaces having the same radius, and the side walls 25, 25 on both sides are bent toward the same side as the tubular flexible portion 22.

In the spacer 21, the space between the side walls 25, 25 has a maximum width in a natural state, and in this state, the space between the widths is variable due to the deformation of the tubular flexible portion 22.

The spacer according to the present invention has the above-described structure, and by incorporating the spacer at an appropriate position of the gap formed between the door 2 and the outer frame 1, the gap is kept constant and rattling of the door 2 is prevented.

As shown in FIG. 3, the spacer 21 is attached to the door 2 by press-fitting the side walls 25, 25 on both sides between the panel supporting walls 6, 6 of the mold member 7 constituting the door frame 9.

At this time, when the tubular flexible portion 22 is fitted so as to be folded from both sides, the spacer 21 is elastically fixed between the panel support walls 6 and 6.

Further, the contact surface 26 of the tubular flexible portion 22 and both plate portions 24, 24 are sandwiched between the door frame 9 and the outer frame 1 to keep the gap at a constant interval and prevent rattling of the door 2.

〔effect〕

As described above, according to the present invention, it is possible to prevent the rattling of the door by keeping the gap between the door and the outer frame constant by simply fitting it into the outer peripheral groove of the door and mounting it. Sexuality can be improved.

In addition, the tubular flexible portion allows a wide range of changes in the mounting width and the gap, and a single structure can cope with different gaps.
