Description

[Detailed description of the invention] (Industrial application field) This invention relates to a tight material used for various types of sashes such as revolving windows and casement windows.

(Prior art) Conventionally, for example, a tight material made of synthetic rubber or the like has protruding elastic fins that are pressed against the window frame in order to maintain watertightness with the window frame on the left and right vertical frames and upper and lower frames of a shoji in a revolving window. However, these tight materials can be used in cases where the shoji is not properly installed on the window frame, or when the window frame is pulled outward from the intended position due to welding and fixed. If the elastic fins are unable to make sufficient contact with the window frame and maintain watertightness, the method is to replace them with new tight material. but,
This conventional method is uneconomical and requires a lot of effort, so it has been desired to improve this point.

(Problems to be solved by the invention) The purpose of the invention is to provide a tight material for satsushi that can meet the conventional demands.

(Means for solving the problem) In order to achieve the above purpose, the tight material for sash of the present invention is characterized by being improved to be repairable, and its structure consists of a mounting part to be attached to the sash, and the above-mentioned mounting part. In the tight material body having elastic fins protruding from the body, the tight material body is provided with a locking portion for locking the repair tight material. An example in which the present invention is applied to a tight material attached to a shoji of a revolving window will be described below with reference to the drawings.

In FIG. 1, the tight material 1 is a long string-like material made of an elastic material such as synthetic rubber, and the main body of the tight material has a rectangular cross section C of a shoji in this example.
Two elastic fins 3, 3 are formed in a structure in which two elastic fins 3, 3 are protruded almost in parallel from a hollow mounting portion 2 having a shape that can be fitted and locked into a tight material fitting groove P, and the mounting portion 2 and two elastic fins 3,
In the U-shaped groove formed by the U-shaped groove 3, protrusions 4, 4 are protruded from the opposing surfaces of both elastic fins 3, 3, and a rectangular cross-section C is formed at the bottom of the U-shaped groove as a repair tight material locking part. A shaped locking groove 5 is formed.

When the above-mentioned tight material 1 is attached to the shoji and the elastic fins 3, 3 cannot make sufficient contact with the window frame, the second
As an example, as shown in the figure, a repair tight material A made of an elastic material such as synthetic rubber, which has a single elastic fin C protruding from a mounting portion B having a shape that can be fitted and locked into the locking groove 5 in the cross section, is used. The mounting portion B is then locked in the locking groove 5 to cause the elastic fin C to protrude longer than the elastic fins 3, 3 from between the elastic fins 3, 3.

Another embodiment 1a in FIG.
The elastic fins 3a of the strip are protruded, and the elastic fins 3a of the strips are protruded.
Locking grooves 5a, 5a having a rectangular C-shaped cross section and having protrusions 4a, 4a are formed on both sides of the base of a. Tight material Aa
is installed by fitting and locking its mounting portion Ba into the locking groove 5a. If necessary, a repair tight material having the same or symmetrical cross-sectional shape as the repair tight material Aa is fitted and locked into the other locking groove 5a.

Further, in the embodiment 1b of FIG. 4, two elastic fins 3b, 3b are protruded from the mounting part 2b, and a U-shaped engagement opening in the left and right sides is provided between the mounting part 2b and the elastic fins 3b, 3b. In the case of repair, for example, as shown in the figure, two grooves are formed on the mounting part Bb, which has a rectangular C-shape in cross section, surrounding the outside of the elastic fins 3b, and reaching the locking grooves 5b, 5b. A repair tight material Ab consisting of elastic fins Cc and Cb protruding from the elastic fins 3 is attached to its mounting part Bb.
b, 3b, and both ends of the mounting portion Bb are locked in the locking grooves 5b, 5b.

(Effects of the invention) According to the tight material for sash of the present invention, when used as a watertight material for windows, for example, when the elastic fins cannot make sufficient contact due to poor construction, etc., the locking portion can be By locking the repair tight material, it becomes possible to compensate for the elastic fins that have a poor contact with the original one, which is extremely advantageous economically.
