JPH108578A - Water drip material and shutter for water drip material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simplify the structure and facilitate the handling and prevent cold air from entering into the underside of a floor by shutting a vent hole in the winter at a cold district, by installing a shutter at the outside face of the vent hole to freely open/close the hole and installing this water drip material at the lower end edge of the external wall of a building. SOLUTION: This water drip material is made of a thin metallic plate or the like and a vent hole 15 is bored in the bottom wall 14 thereof. A shutter 20 is arranged at the outside face of the vent hole 15 so as to freely and rotatably open/close. The shutter 20 is composed of a belt-form shutter plate and a fitting metal tool. The fitting metal tool is provided with a shutter platesupport connected by hinges, a fitting leg, and a lock piece. The shutter 20 is made detachable against the water drip material 10 to facilitate the cleaning work and easily exchange the shutter when it has been broken. The fitting metal tool of the shutter 20 is made of an elastic metallic plate to easily fix the water drip material 10 at the vent hole 15 and retain the closed state in a simple structure. In this way, the manufacturing cost is reduced and the vent hole 15 can be freely opened/closed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage material attached to a lower edge of an outer wall of a building such as a house, and more particularly to a drainage material having a vent hole in a bottom wall, and a shutter attached to the drainage material. About.

[0002]

2. Description of the Related Art In order to guide rainwater flowing down the outer wall of a house to the outside and make it drip, a drainer is usually attached to the lower edge of the outer wall. As this drainer, a type that has a large number of ventilation holes on the bottom wall to ensure sufficient ventilation and to prevent the invasion of rats and the like,
It has already been proposed by the present inventor (Japanese Utility Model Application No. Hei 8-5119).

[0003]

However, in the above drainer, since the vent hole is always open, outside air can freely flow under the floor through the vent hole at any time.
A large air flow is generally preferred in terms of underfloor ventilation, but in cold regions, powdered snow and cold air enter the floor together with outside air during the winter, reducing the indoor heating effect and reducing water pipes. There is a problem with freezing.

[0004] In view of the above, the present invention has been made to provide a drainer capable of closing a ventilation hole in winter or the like to prevent cold from entering under the floor. Another object of the present invention is to provide a shutter having a ventilation hole which can be easily attached to a drainer and used.

[0005]

The technical means of the drainer of the present invention is a drainer having a vent hole in a bottom wall portion.
The vent is openable and closable.

[0006] A shutter may be mounted on the outer surface of the ventilation hole so as to be rotatable and openable. Further, the shutter may be detachable.

The technical means of the shutter according to the present invention comprises a thin band-shaped shielding plate and a mounting bracket provided at an appropriate position on the shielding plate, and the mounting bracket is fixed by being inserted into a shielding plate support portion and a ventilation hole. And a lock mechanism for maintaining a closed state, and the shielding plate support and the mounting foot are rotatable by hinges.

[0008] The mounting bracket may be made of an elastic metal plate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a drainer and its shutter according to the present invention. FIG. 1 shows the mounting and use state of the drainer 10, 1 is a cloth foundation, 2 is a base, 3 is an exterior material, and 4 is a mortar layer formed on the front and upper surfaces of the cloth foundation. Reference numeral 5 denotes a ventilation slit formed by interposing a base packing between the mortar layer 4 and the base 2 on the upper surface of the cloth base.

Reference numeral 10 denotes a drainer, which comprises an attachment wall 11, an inclined projecting wall 12, a projecting end wall 13, and a bottom wall 14. This draining material is usually processed by sheet metal processing from a thin metal plate such as a thin steel plate, a thin aluminum plate, a thin stainless steel plate,
Alternatively, it is manufactured by extrusion processing of an aluminum alloy, a synthetic resin material, or the like. A large number of ventilation holes 15 are formed in the bottom wall portion 14 as shown in FIG. The size and number of the holes 15 are set so that a sufficient amount of air can be obtained and entry of rats and the like can be prevented.

A shutter 20 is attached to the vent hole 15 so that the hole can be easily opened and closed. One embodiment of the shutter 20 is shown in FIGS.
Reference numeral 21 denotes a shielding plate made of a thin band-shaped metal plate. Shield plate 2
The length of 1 is free and may be the same as the length of the draining material 10, or a plurality of shielding plates 21 may be connected to have the same length as the draining material 10. In the embodiment, 3
Two 1870 mm shield plates 21 are connected to the 750 mm drainer 10. The shielding plate 21 abuts on the outer surface of the bottom wall portion 14 to entirely shield all the ventilation holes 15.

Reference numeral 22 denotes a mounting bracket, which is mounted on the shielding plate 21 at appropriate intervals. In the embodiment, the mounting brackets 22 are provided at intervals of 432 mm with respect to the shielding plate 21 of 1870 mm. The mounting bracket 22 includes a shielding plate support portion 23 and a mounting foot portion 24, both of which are rotatably connected by a hinge 25. Two elastic insertion feet 2 are attached to the mounting feet 24.
The foot 26 is fixed by fitting the foot 26 into the vent hole 15. Note that this is easily removable. A handle 27 for opening and closing operation is provided on the support portion 23.
With.

Reference numeral 28 denotes a lock piece which is provided on the mounting foot portion 24. When the lock piece 28 is closed, the hole 2 of the handle 27 is closed.
9 and is kept closed by its elastic locking force. Since the lock is held by the elasticity of the lock piece 28, the holding can be easily released by pulling the handle 27 and the state can be shifted to the open state. In the embodiment, as shown in FIG. 3, the mounting bracket 2 having the handle 27 and the lock piece 28 is used.
2 and a mounting metal which does not have these but merely has a rotation support function are mounted on the shielding plate 21 every other one. The mounting bracket 22 having the above-described shape is preferably made entirely of an elastic metal material, and is made of spring stainless steel in the embodiment.

The present invention is not limited to the above embodiment, but can be freely modified and implemented within the scope of the claims. In particular, in a drainer, the shape and structure of the shutter are free. Further, in the shutter, the shape of the shield plate is free, and further, the shape and structure of the mounting foot portion and the shield plate support portion in the mounting bracket, and the type of the lock mechanism in the closed state are also free.

[0015]

According to the drainage material of the present invention, the ventilation holes can be opened and closed freely. For example, in a cold region, the ventilation holes are closed to prevent the inflow of powdered snow and cold air under the floor, and to freeze the water pipe. Can be prevented.

According to the second aspect, since the shutter is mounted on the outer surface of the ventilation hole to be opened and closed, the structure and handling are simple and excellent in practicality.

According to the third aspect of the present invention, the shutter is detachable, which is convenient for cleaning work and replacement when the shutter is damaged.

The shirtter of the present invention can be freely attached to a drainer having a vent and used, and the opening and closing operation is simple, so that it is practically convenient. In addition, since the belt-shaped shielding plate is supported at the appropriate position by the mounting bracket, the structure is simple and the device can be manufactured at low cost.

According to the fifth aspect, since the mounting bracket of the shutter is made of an elastic metal plate, the drainer can be fixedly held to the ventilation hole or held in a closed state with a simple structure.
