Description

  The present invention relates to a door stop and a door stop structure in which legs are fitted and attached to two parallel grooves or one groove formed in a door frame.

  A door stop is attached to the door frame to which the door is attached, and functions as a stopper for the door to be closed and to prevent a gap from being formed between the door frame and the door frame. Incidentally, although there are various types of door stops, FIG. 4 shows a typical door stop of a conventional door. The door stop (A) has two legs (B) and (B) parallel to each other, and the legs (B) and (B) extend from both sides of the door stop main body. As shown in FIG. 5 which is an enlarged sectional view of the leg (b), a plurality of saw teeth (h), (h) are formed on both side surfaces.

  On the other hand, fitting grooves (e) and (e) are provided on the inner surface (d) of the vertical beam (c) constituting the door frame, and both the legs (ro) are provided in the fitting grooves (e) and (e). ), (B) are fitted and attached. That is, the vertical rail (c) is attached to the frontage as a door frame in a state where the fitting grooves (e) and (e) are processed. The door stop (a) is provided with a cushioning material (f), which can alleviate the impact when the door is closed.

  FIG. 4B shows a state in which a door stop (A) is attached to the vertical beam (C) and the door end is in contact with the door stop (A) and is closed. The two legs (b) and (b) are fitted into the fitting grooves (e) and (e), and the saw teeth (h) and (h) are fitted into the fitting grooves (e) and (e). By partially biting into the inner surface of the door, the door stop (a) is not easily removed. Incidentally, the fitting grooves (e) and (e) provided in the vertical beam (c) are parallel to each other at a predetermined interval.

  However, the dimensional accuracy of the extruded door (a) is not so high, and the distance between the legs (b) and (b) varies. Of course, there is also a variation in the interval and groove width between the two parallel fitting grooves (e) and (e). Furthermore, there is also a variation in the distance M between the tips of the saw teeth (h) formed on both sides of the leg (b). For this reason, the legs (b), (b) ) Is difficult to fit. On the contrary, if the leg width dimension M is too small, it will be easy to come off.

Japanese Patent Laid-Open No. 2004-178272 “door stop material” is designed to be easily mounted in a fitting groove provided in a mounting frame, and the door stop material is connected to the door stop portion and the door stop portion. The insertion portion is composed of two left and right insertion portions to be inserted into the insertion groove, and each insertion portion includes a support leg portion, an arm portion extending inwardly from the tip end portion of the support leg portion, and a tip end of the arm portion. It is comprised from the inclination piece extended diagonally so that V shape might be formed. The door stop material is attached with the two left and right insertion portions fitted into the insertion groove, but the distance between the two insertion portions is bent and deformed, so that it can be fitted into the large insertion groove relatively easily. For this reason, the fitting strength is low and it is easy to come off.
"Door material" according to Japanese Patent Application Laid-Open No. 2004-178272

  As described above, the conventional door has problems as described above. The door stop of the present invention is provided with two legs, and even if there are variations in the distance between the legs, the width of the legs, and the dimensions of the fitting groove, the legs are fitted and attached to the fitting groove. It is possible to provide a door-to-door structure and a door-to-door structure that can be easily removed.

  The door stop of this invention consists of a door stop part and two legs, and uneven | corrugated | grooved parts, such as a sawtooth, are formed in the both surfaces side of the two legs extended from the both sides of a door stop. However, although one surface side of the uneven portion is made of the same hard resin as the leg, at least the convex portion of the uneven portion on the opposite surface side is formed of a soft resin. Sometimes the convex portions on both sides are made of soft resin. As in the prior art, two parallel fitting grooves are provided on the vertical beam constituting the frame, and the door ends are attached by fitting the two legs into the fitting grooves.

  Here, since the convex portions provided on both sides of the legs are made of soft resin at least on one side, even if the distance between the convex tips on both sides is large, the convex portions are compressed and easily fit into the fitting grooves. I can do it. On the other hand, in the present invention, there may be a structure in which the tips of both legs are connected by joining. In this case, a convex portion made of a soft resin is formed on the outer surface of both legs. Therefore, a wide fitting groove is provided in the vertical beam and both legs are fitted. Further, even when the tips of both legs are not connected by joining, it is possible to fit in the wide fitting groove.

  The door stop of the present invention has two legs, and these two legs are fitted and attached to two fitting grooves provided in the vertical beam of the frame. The basic structure of this door stop is the same as that of the prior art, but at least one side of the protrusions formed on the leg side surface of the door stop of the present invention is made of a soft resin. Since the convex portion of the soft resin can be compressed and deformed when the leg is fitted into the fitting groove, the door stop can be easily attached.

  In addition, since the convex portion of the soft resin is compressed and deformed and fitted into the fitting groove, the door stop does not come off from the fitting groove of the vertical rail, and stable attachment is performed. And, even when both ends of the legs having soft resin convex portions formed on the outer surface are connected by connecting or not connected by connecting, the convex portions of the soft resin when fitting into the wide fitting groove Can be compressed and deformed, and the distance between the legs can be reduced.

  FIG. 1 is an embodiment showing fitting grooves 2a and 2b provided in a door stop 1 and a vertical rail 3 according to the present invention. The door stop 1 includes a door stop portion 4 having a U-shaped cross section and two legs 5a and 5b. The side piece portion 6 of the door stop portion 4 has a buffer piece 7 formed of a soft resin. And leg 5a, 5b is extended at the front-end | tip of said side piece part 6a, 6b, and the saw-tooth which is one form of an uneven | corrugated | grooved part is formed in the both sides | surfaces of leg 5a, 5b. Therefore, as the shape of the concavo-convex portion, in addition to the sawtooth, a triangular convex portion, a semicircular convex portion, etc. may be formed, but the convex portion where the legs 5a and 5b fitted in the fitting groove are difficult to come off is the sawtooth shape. Is excellent.

  Two fitting grooves 2a and 2b having a predetermined interval A extend in parallel with each other on the surface of the vertical beam 3, and the legs 5a and 5b of the door stop 1 are provided in the fitting grooves 2a and 2b. fit. By the way, the distance A between the inner side surfaces of both fitting grooves 2a, 2b is slightly larger than the distance B between the inner sides of both legs 5a, 5b. For example, by enlarging in the range of 0.5 mm to 1 mm, the both legs 5a and 5b are slightly expanded when fitted into the fitting grooves 2a and 2b.

  The width dimension C of the fitting grooves 2a and 2b is slightly smaller than the width dimension D of the legs 5a and 5b. Thus, since the distance B between both legs 5a and 5b and the distance A between both fitting grooves 2a and 2b are different and the leg width D is larger than the fitting groove width C, the legs 5a and 5b are fitted. It is basically impossible to fit in the grooves 2a and 2b. However, in the present invention, the saw teeth formed on the side surfaces of the legs 5a and 5b are made of a soft resin.

  FIG. 2 shows an enlarged cross-sectional view of the leg 5a. Saw teeth 8a, 8b and 8c are provided on the left side of the leg 5a, and saw teeth 9a, 9b and 9c are provided on the opposite right side. And the saw-tooths 8a, 8b, 8c on the left side surface are formed of a soft resin different from the material of the legs 5a. However, the saw-tooths 9a, 9b, 9c on the right side are formed of a hard resin made of the same material as the legs 5a.

  Therefore, the saw-tooth 8a, 8b, 8c made of a soft resin can be compressed and deformed with respect to an external force, and even if the width C of the fitting groove 2a is slightly small, the saw-tooth 8a, 8b, The leg 5a can be fitted in the fitting groove 2a by deforming the tip of 8c. In addition, the leg 5a fitted in the fitting groove 2a has the tips of the hard resin saw teeth 9a, 9b, 9c bite into the inner surface of the fitting groove 2a by the restoring force of the soft resin saw teeth 8a, 8b, 8c. As a result, the leg 5a does not come off the fitting groove 2a.

  FIG. 2 shows the case of the left leg 5a of the door stop 1 shown in FIG. 1, but the case of the right leg 5b can be similarly configured. That is, the saw tooth provided on the right side surface of the leg 5b is made of a soft resin, and the saw tooth provided on the left side surface is made of the same hard resin as the leg 5b, so that the leg 5b can be easily fitted into the fitting groove 2b and hardly come off. . It is also possible to provide the positions of the soft resin saw teeth 8a, 8b, 8c on the inner side of the leg 5a, that is, the saw teeth on either side of the legs 5a, 5b may be made of soft resin.

  By the way, the specific shape of the saw teeth 8a, 8b, 8c, 9a, 9b, 9c formed on the legs 5a, 5b is not particularly limited, and the number of saw teeth formed is also arbitrary.

  On the other hand, in the door stop of the present invention, both saw teeth 8a, 8b, 8c and 9a, 9b, 9c formed on both legs 5a, 5b may be formed of a soft resin. Accordingly, when fitting into the fitting grooves 2a and 2b, both the saw teeth 8a, 8b and 8c and 9a, 9b and 9c are made of soft resin, so that they can be easily deformed and attached. At the same time, the saw-tooths 8a, 8b, 8c and 9a, 9b, 9c of the legs 5a, 5b once fitted closely contact the inner side surfaces of the fitting grooves 2a, 2b to prevent detachment.

  FIG. 3 shows another embodiment of the door stop 4 according to the present invention. The vertical rail 3 is provided with a wide fitting groove 10, and legs 11 a and 11 b are fitted into the fitting groove 10 to attach the door stop 4. The legs 11 a and 11 b extend from the side pieces 6 a and 6 b of the door stop 4, and the tips of both legs are connected by a generally inverted V-shaped connection 12. And saw-tooth 13a, 13a ... and saw-tooth 13b, 13b ... are formed in the outer surface of both legs 11a, 11b.

  Therefore, when both the legs 11a and 11b are fitted in the wide fitting groove 10, the crossing angle of the inverted V-shaped joint 12 is reduced and the distance between the both legs 11a and 11b is reduced. The soft resin saw teeth 13a, 13a,... And 13b, 13b,... Formed on the outer surface are compressed and fit into the fitting groove 10. In the fitted state, the elastic restoring force of the joint 12 and the legs 11a, 11b and the restoration of the saw teeth 13a, 13a,..., 13b, 13b,. become.

  However, in the present invention, the shape of the joint 12 is not limited to the inverted V shape. Further, the ends of both legs 11a and 11b may not be connected by joining, and two legs 11a and 11b having soft resin saw teeth 13a, 13a... 13b, 13b. It can also be fitted in the groove 10.
