Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an auxiliary roof/house guard that can be used as an auxiliary roof in the summer and as a snow enclosure in the winter.

Prior Art As shown in Japanese Utility Model Application Publication No. 58-2201, one end of the roof is connected to the outer wall of a building so as to be movable up and down, and a column is removably connected to the other end of the roof. An auxiliary roof and house guard that can be used as a snow enclosure by removing the pillars and rotating the roof downward.

As shown in Japanese Utility Model Application Publication No. 60-105701, a second roof is foldably connected to a first roof that is vertically movably connected to the outer wall of a building, and a telescopic column is connected to this first roof. This is an auxiliary roof and house guard that can be used as a snow enclosure by reducing the number of pillars and rotating the second roof downwards so that it touches the ground.

Problems that the invention aims to solve When the roof is used as both an auxiliary roof and a house guard, the length of the roof is constant, so when used as an auxiliary roof, the area of the auxiliary roof is constant and depends on the purpose and building site. The auxiliary roof area cannot be adjusted according to the area.

The former type of auxiliary roof and house guard requires the removal of the supports when used as a snow enclosure, which makes the work cumbersome, and the roof itself supports the weight of accumulated snow, so it is not strong enough. Because the roof becomes weak and cannot support the heavy snow that accumulates high, and the weight of the snow acts directly on the connection between the roof and the outer wall of the building, it is necessary to strengthen the strength of that connection. The structure becomes complex and large.

If the latter is used as an auxiliary roof and house guard, it would be necessary to extend and contract the supports, and to attach and fix the second roof to the first roof, and to release it, making the work cumbersome and causing the structure to deteriorate. More complex and costly.

Means and action for solving the problem: A movable rafter is slidably attached to a rafter that is connected to the outer wall of a building so that it can move up and down, and a support column is connected to the lower surface of the movable rafter so that it can move up and down. By rotating the roof and rafters up and down, it can be used as an auxiliary roof or as a snow enclosure.

Example: An opening B is formed in the outer wall A of the building, allowing people to enter and exit freely. An eaves C is installed above the opening B, and below the eaves C are a plurality of rafters that make up the roof. The base end of each rafter 1 is connected with a bracket 2 and a pin 3 so as to be movable up and down, and a movable rafter 4 is slidably fitted and attached to each rafter 1, and the tip of each movable rafter 4 is A front frame 5 is attached across the space, and a roof material 6 is attached between the front frame 5 and the movable rafters 4 on both the left and right sides, and the upper part of the support column 7 is connected to the top of the movable rafter 4 by a connecting tool. 8 and are connected to each other so that they can move up and down.

Because of this, by extending the movable rafters 4 as shown by the imaginary lines in FIG. 1, the area of the auxiliary roof can be easily increased or decreased by adjusting the width when used as an auxiliary roof.

At this time, the roofing material 6 is attached only to the movable rafters 4, but there is no problem since the eaves C are provided.

In addition, when there is no eaves C, the roofing material may be made expandable and contractible, and both edges may be fixed to the movable rafters 4 and the rafters 1.

In addition, when using it as a snow enclosure, as shown in FIG. It is only necessary to ground the tip of the rafter 1, that is, the front frame 5, which makes the operation very simple, and because the support column 7 can be in contact with the outer wall A to support the weight of accumulated snow, the outer wall A of the rafter 1 It is possible to prevent a large load from being applied to the connecting portion.

Furthermore, by expanding and contracting the movable rafters 4 relative to the rafters 1, the space between them and the outer wall A of the building can be adjusted as desired.

The rafters 1 are connected to the upper and lower walls 1 as shown in FIG.
a, 1b and both side walls 1c, 1c form a hollow elongated member with a substantially rectangular cross section, and a U-shaped guide groove 10 opened laterally is formed in the longitudinal direction on both side walls 1c, 1c. The bottom portion 10a of the guide groove 10 has an upward U-shape as shown in FIG. 5, and is provided with a plurality of grooves 11 extending in the longitudinal direction to serve as escape grooves for dust, sand, etc. A recessed portion 12 is formed in.

The movable rafter 4 is attached to the upper wall 4 as shown in FIG.
a and the side walls 4b, 4b form a long member with a substantially downward U-shaped cross section, and the upper piece 14a and the side pieces 14 are formed along between the upper wall 4a and the intermediate protrusion 13 of the side walls 4b, 4b.
The roller frame 14 has a downward U-shape with b and 14b.
A roller 15 is rotatably attached to both side pieces 14b, 14b with a support shaft 16, and this roller 15 is in contact with the bottom 10a of the guide groove 10, and the movable rafter 4 is moved by the roller. 15 to bottom 1
0a and extends to a predetermined extended position, the roller 15 is lowered facing the recess 12 as shown in FIGS. 6 and 7, and the roller frame 14
The upper piece 14a comes into contact with the upper wall 1a of the rafter 1, so that the roller 15 does not come into contact with the bottom part 10a, so that no load is applied to the roller 15 when used as a snow fence as shown in FIG. It's like this.

That is, the roller 15 touches the bottom 1 of the guide groove 10.
0a, the gap between the upper wall 1a of the rafter 1 and the upper piece 14a of the roller frame 14 is smaller than the depth of the recess 12, and when the roller 15 descends facing the recess 12, the upper wall 1a of the rafter 1 The upper piece 14a of the roller frame 14 comes into contact with the upper piece 14a of the roller frame 14, and the roller 15 does not come into contact with the recessed portion 12.

The upper parts of the movable rafters 4 and support columns 7 are shown in FIGS. 8 and 9.
They are connected as shown in the figure.

That is, a hollow pipe-shaped girder 20 is horizontally suspended between each of the movable rafters 4, and a collar 22 having a pair of annular recesses 21 is fitted to the outer peripheral surface of this girder 20. Recesses 21, 2
Both side walls 7 of the support column 7 are placed on the upper outer circumferential surface 22a between the
The arcuate portion 23a of the tightening band 23 fixed to the movable rafter 4 is tightly attached to the lower outer circumferential surface 21a of the pair of annular recesses 21. In close contact with the annular recess 2
The upper outer circumferential surface 21b of the liner 25 is pressed against the arc-shaped concave surface 25a of the liner 25 fixed to the movable rafter 4, thereby connecting the movable rafter 4 and the support column 7 so as to be movable up and down.

In addition, hook pieces 4 are attached to the upper walls 4a of the movable rafters 4 on both sides.
c is formed, and the roof material 6 is supported by this hook piece 4c.

Effects of the invention Since the overhang length can be adjusted by expanding and contracting the movable rafters 4, the area of the auxiliary roof can be easily increased or decreased when used as an auxiliary roof.

Fold the support column 7 so that it touches the movable rafter 4,
In this state, by rotating the rafter 1 downward and touching the tip of the movable rafter 4 to the ground, it can be used as a snow enclosure.
It can be used as an auxiliary roof or a snow fence with a simple operation, and the weight of accumulated snow can also be supported by the pillars 7 by contacting the outer wall A with the pillars 7 in contact with the lower surface of the movable rafters 4. This prevents a large load from acting on the joint between the rafters 1 and the outer wall A, and when used as a snow fence, the space between the rafters 4 and the outer wall A can be increased or decreased by expanding and contracting the movable rafters 4. can.
