Abstract

PURPOSE:An object of this invention is to provide the roof-top of a dwelling house which can be put into good use not only when it is fine but also when it is rainy and windy. CONSTITUTION:A roof frame 25 roughly in a triangle shape made up of a ridge piece 23 which is horizontally arranged, and of rafters 24 which are obliquely arranged, is provided for the roof-top 20 of an unit dwelling house 1. Guide members 37 are provided along the longer direction of each rafter 24, and shutters 30 acting as a surface shielding member are housed in at one end side of each rafter 24 so as to be taken up, each shutter 30 is so designed that it can be pulled out along each guide member 37, and the roof-top 20 is formed in such a manner that the roof-top can prevent wind and rain from coming in the frame 25 with the slant of the frame 25 roughly in a triangle roof shape shielded with the shutters 30.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to residential rooftops, and more particularly to improvements to walkable residential rooftops.

0002

BACKGROUND ART Conventionally, some houses have been provided with walkable rooftop terraces and the like. The roof of such a house is an open space with no roof covering the top, so it has good ventilation and receives strong sunlight, making it an ideal place for outdoor work such as drying laundry.

0003

[Problems to be Solved by the Invention] However, since laundry and the like are exposed to the wind and rain on the rooftops of conventional houses, there is a problem in that they cannot be used for drying laundry during rainy weather or strong winds. An object of the present invention is to provide a roof of a house that can be used not only on sunny days but also on rainy days and strong winds.

0004

[Means for solving the problems] The roof of the house of the present invention is
A substantially triangular roof-shaped frame formed by a horizontally arranged purlin and an inclined rafter is provided, a guide member is provided along the longitudinal direction of the rafter, and the guide member is housed at one end of the rafter. It is characterized by providing a planar shielding member that can be pulled out along.

[0005]

[Operation] According to the present invention, by pulling out the planar shielding member housed at one end of the rafter and blocking the inclined surface of the approximately triangular roof-shaped frame with the planar shielding member, it is possible to prevent water from flowing into the frame. This makes it possible to block wind and rain. This achieves the above objective.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show the upper part of a unit house 1 according to this embodiment, and the unit house 1 was constructed by combining a plurality of roof units 2 and living room units 3 that were manufactured in advance at a factory. It is something.

[0007] Each roof unit 2 is joined onto each living room unit 3 to form a roof portion 4. Among the roof units 2, those arranged on both sides of the roof part 4 are provided with a sloped roof 2A. A penthouse 5 is formed in the center of the roof 4, and a walkable rooftop 1 is provided on both sides of the penthouse 5.
0, 20 are formed.

[0008] The rooftop 10 on the right side of the figure has a nearly horizontal floor 1
1, and a rising wall 1 formed around this floor portion 11.
2. A substantially triangular roof-shaped frame 15 is installed on the upper surface of the rising wall 12, and is formed by a horizontally arranged purlin 13 and an inclined rafter 14.

Similar to the rooftop 10, the rooftop 20 on the left side of the figure includes a floor portion 21 and a rising wall 22, and a substantially triangular roof-shaped frame formed by a purlin 23 and a rafter 24 on the upper surface of the rising wall 22. 25 have been installed. Rafter 2
A square cylindrical storage member 26 is installed along the longitudinal direction at one end of the upper side of 4, and this storage member 26 is attached to the purlin 2.
It is joined to 3. A shutter 30, which is a planar shielding member, is rolled up and stored in the storage member 26.

The shutter 30 has a large number of long strip-shaped fins 31. As shown in FIG. 4, both end portions of each fin 31 are connected by a strip member 32 such as a wire, and a support shaft 33 is provided in the center portion. Both ends of each support shaft 33 are rotatably connected to a chain 34, respectively. These strip members 32 and support shafts 33 allow the rotation angle of each fin 31 to be adjusted when the shutter 30 is closed, and the rotation angle positions thereof are linked together.

The proximal edge of the chain 34 is connected to the circumferential surface of a take-up roller 35 within the storage member 26, and a rectangular cylindrical starter member 36 is provided at the distal edge. On the other hand, a guide member 37 having a U-shaped cross section is fitted into the rafter 24 of the frame 25 along its longitudinal direction. The inner surface of the guide member 37 is adapted to guide the chain 34 and the side surfaces of the starter member 36. Thereby, the shutter 30 can be pulled out along the guide member 37, and the starter member 36, which is the leading edge of the shutter 30, can slide from the upper end to the lower end of the rafter 24.

In this embodiment, the shutter 30 is pulled out from the storage member 26 on the upper end side of the rafter 24, and the shutter 30 closes the inclined opening surface of the frame 25 having a substantially triangular roof shape, so that the light passing through the opening surface is and frame 25
Direct sunlight and wind and rain that try to get inside are blocked. For this reason, the rooftop 20 is normally an outdoor space, but when the shutter 30 is closed, it becomes an indoor space.

According to this embodiment as described above, the following effects can be obtained. That is, by fully closing the shutter 30, the rooftop 20 is made into an indoor space, so that wind and rain can be blocked out in rainy weather, and the rooftop 20 can be used not only in sunny weather but also in rainy weather.

Furthermore, the rotation angle of each fin 31 can be adjusted, so that even when the shutter 30 is fully closed, the frame 25
Since the inside of the frame 30 can be ventilated, laundry will not be scattered outside the frame 30 even in strong winds, and the fins 3
By changing the angle of step 1, you can adjust the amount of air flowing in and the amount of sunlight irradiated, and by making these adjustments, you can dry your laundry under better conditions depending on the weather.

Furthermore, if the shutter 30 is half-closed as shown in FIG. 2, the shutter 30 can be used as a sunshade to protect the skin from intense direct sunlight when sunbathing on the rooftop 20.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, the planar shielding member is not limited to the shutter 30 of the above embodiment, but may also include, for example, a single sheet 40 such as a waterproof cloth or a vinyl sheet, or a plurality of flat members, as shown in FIG. It may be hinged so that it can be folded in a zigzag manner, and in short, any surface material that can be stored compactly may be used.

Further, the winding position of the planar shielding member is not limited to the upper end side of the rafter 24, but may be the lower end side.If the winding position is set at the lower end side of the rafter 24, as shown in FIG.
Place the winding roller 35A in the attic 2B of the roof unit 2.
It can be stored inside, making effective use of dead space in the attic 2B.

Further, in the above embodiment, the shutters 30 are housed on both slopes of the triangular roof-shaped frame 25, but the shutters 30 may be housed only on one side of the slope. In this case, the top of the frame 25 may be rounded, and the shutter 30 may be installed so as to extend beyond the top of the frame 25 and close the opposite slope.
