Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap that is fixed to a parapet, and more particularly to a cap that blocks a gap between the parapet and the cap to prevent rainwater and insects from entering.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Application Laid-Open No.
Japanese Patent No. 95470 discloses that a bracket having a U-shaped cross section is fixed to a bracket fixed to a parapet, and a lip-shaped elastic pressing member attached to a side plate portion of the bracket is attached to a parapet with a parapet. Kasagi have been proposed in which a gap formed between the parapet and the kasagi is closed to prevent rainwater or insects from entering the space formed between the parapet and the kasagi.

[0003] When attaching a resilient pressing member longer than the gap between the heddle and the parapet on the side plate of the heddle, the heddle is placed on the parapet from above and fixed to the bracket.
Although the elastic pressing member that comes into contact with the rising portion of the parapet is bent inward, the cap and the elastic pressing member attached to this cap are simply a cylindrical engaging portion formed on the outer edge of the elastic pressing member. Since the elastic pressing member is fixed by the concave-convex fitting of the engaged portion having the C-shaped cross section formed by the elastic pressing member, the elastic pressing member may come off when a strong tensile force is applied to the elastic pressing member. In particular, a parapet formed of concrete has a relatively rough surface, and when an elastic pressing member made of a flexible material such as rubber is bent in a curved shape along the parapet, a strong tensile force acts on the elastic pressing member. The elastic pressing member is easily detached. In addition, the sash fixed to the bracket is fixed by screwing an L-shaped arm piece vertically hanging on the back side of the top plate portion of the sash to a support portion protruding from a horizontal portion on the upper surface of the bracket. Therefore, although the top of the sash is fixed, the lower end of the side of the sash is a free end, and when an external force is partially applied to the side of the sash, the side can easily move outward or inward. It will be deformed. For this reason, the deformation of the side portion of the heddle causes the gap between the heddle and the parapet to be locally narrow or locally widened, so that the elastic member that closes the gap between the heddle and the parapet does not bend uniformly, The pressing member may be deformed in a wavy manner, and the appearance is unsightly.

The present invention is intended to solve such a problem. A waterproof cover for closing a gap between a cap and a parapet can be prevented from coming off and can be firmly fixed, and a deformation of a side plate of the cap can be prevented. Accordingly, an object of the present invention is to provide a cap that can bend the waterproof cover uniformly and adhere to the parapet.

[0005]

According to the first aspect of the present invention, there is provided a bracket having a U-shaped cross section which is fixed to a top end of a parapet at a predetermined interval, and a cap which is fixed to the bracket and covers the parapet. In a heddle provided with an elastically deformable waterproof cover that closes a gap between the heddle and the parapet, the hedder is formed into a U-shaped cross section by vertically suspending a pair of side plates from both sides of a top plate. At the lower end of the side plate portion, a flange portion to be engaged with the lower end edges on both sides of the bracket is integrally formed inward, and an engagement convex portion having a substantially semicircular cross section is formed at the outer end edge of the flange portion. The base of the waterproof cover has a fitting groove of the engaging protrusion, and an engagement receiving portion having a substantially C-shaped cross section is formed. The wedge-shaped projection that locks to the step of the projection is integrated into the inside One in which the.

When assembling the shed and the waterproof cover, a C-shaped engaging receiving portion formed on the waterproof cover is inserted into a semicircular locking projection formed on the flange of the shed. At this time, when the engagement receiving portion of the waterproof cover bends along the locking convex portion to expand in diameter and the locking convex portion is inserted into the fitting groove, the engagement receiving portion elastically returns to return to the engagement convex portion. The wedge-shaped projection of the engagement receiving portion is locked to the step portion of the portion, whereby the waterproof cover is attached to the flange portion of the coping so as not to come off. After that, to fix the Kasagi,
Cover the parapet on the parapet in a state where the side plate of the cap is opened outward and elastically deformed. At this time, the waterproof cover comes into close contact with the rising portion of the parapet and bends inward with the insertion of the coping. Then, the side plate portion is elastically restored, and a flange portion formed at the tip of the side plate portion is locked to the tip end side of the bracket to fix the cap to the bracket. The cap fixed to the bracket is fixed in a state in which the flange formed at the end of the side plate is held by the bracket, and the deformation of the side plate is prevented. For this reason, since the distance between the side plate portion and the parapet can be kept substantially constant, the waterproof cover attached to the flange portion of the heddle bends uniformly along the rising portion of the parapet without waving.

According to a second aspect of the present invention, in the headstock according to the first aspect, the step portion and the wedge-shaped projection are formed in an inverse taper,
Further, a tapered portion for inducing the engagement convex portion is formed at a tip portion of the fitting groove. Thus, the engagement receiving portion of the waterproof cover is guided by the tapered portion formed on the tip side of the wedge-shaped projection, and the locking projection is smoothly inserted into the engagement receiving portion. Also, the engagement of the wedge-shaped projections formed in the reverse taper and the steps of the locking projections ensures that the waterproof cover is securely prevented from falling off even when the cap is attached to a roughened concrete parapet. You.
