Description

[Detailed description of the invention] [Industrial application field] This invention relates to an awning (sunshade) that is attached to the outer wall of a building such as the eaves of an entrance/exit, and in particular relates to a movable awning in which the sunshade sheet can be unfolded and folded. It is.

[Conventional technology]

For example, conventionally, a movable awning is attached to the outer wall of a building such as a store to shade the eaves of the entrance. However, due to mechanical difficulties, the above-mentioned movable awning can only be attached to the flat side wall of the outer wall of a building, and fixed awnings as shown in FIG. 5 have been attached to the corners of the outer wall. FIG. 5 is an overall perspective view showing the corner fixed awning. This fixed corner awning A' is a known movable awning D' attached to both sides of the building B' corner C'.
Two fixed columns A' ₂ and A' ₂ are positioned between D'. Additionally this corner fixed awning
A' has _a substantially triangular sunshade sheet A'1 stretched at the same angle as the protruding inclination angle of the sunshade sheets D' ₁ , D' ₁ of the adjacent movable awnings D', D'.

[Problem that the invention attempts to solve]

The conventional corner fixed awnings described above have the following problems.

A: Fixed corner awnings have fixed pillars placed upright on the walkway, which poses a problem in that they become an obstruction to traffic.

(b) Since the sunshade sheets were fixedly stretched, they could not be rolled up or removed, which created an obstacle when sunlight and ventilation were desired.

C. Also, when the movable awning adjacent to the corner fixed awning is closed and the day's sheet is rolled up, only the corner fixed awning remains.
There was a problem that it created a sense of discomfort and spoiled the exterior beauty of the building.

This idea was made in view of the above problems, and does not require fixed pillars, and the solar shade sheet can be unfolded and folded, so it does not require a large storage space, and can also be applied to the corners of external walls of buildings. The technical problem is to provide a movable awning that is possible.

[Means for solving problems]

In order to solve the above problems, this invention has an arc-shaped guide body fixed horizontally to the outer wall, a plurality of support arms movably engaged with this guide body, and a connection between the support arms. a binding biasing means that always biases in the retracting direction; a return biasing means that connects one end support arm of the support arm with one side wall of the outer wall and always biases in the retracting direction; and the other side wall of the outer wall. The movable awning includes a drive mechanism that is fixedly attached to the movable awning and that allows the support arms to move along the guide body, and a sunshade sheet that is stretched between the support arms.

[Effect]

According to this invention, when unfolding the sunshade sheet, by operating the drive mechanism and pulling out the support arms, each support arm is moved against the biasing force of the binding biasing means and the return biasing means, and the guide body , the sunshade sheet stretched between the support arms is unfolded and stretched out on the outer wall. Furthermore, when folding the sunshade sheet, by operating the drive mechanism in reverse, each support arm is folded by force and moved along the guide body by the binding biasing means and return biasing means of each support arm. Therefore, the sunshade sheet is folded and stored on one outer wall of the guide body.

Further, the sunshade sheet 9 is attached to the support arm 2.
...A fan-shaped sunshade sheet 9 covering the space is stretched over the arm portion 2a by adhesive or pin. In this embodiment, the sunshade sheet 9 is connected to the support arm 2.
It is designed to be formed over approximately 90° with the length of ... as a radius when expanded. Therefore, when the support arms 2 are pulled out, the sunshade sheet 9 is unfolded and extended into the space of the outer wall corner C. Further, when the support arms 2 are folded, the sun shade sheet 9 is also folded in conjunction with this.

The corner movable awning A constructed as described above operates as follows. First, when unfolding the sunshade sheet 9, the electric motor 6 is activated to rotate the wire drum 7 in the opening direction, and the wire rope 8 is wound up, so that the support arms 2... , 4b, . . . and is pulled out against the biasing force of the return twisting fill spring 5 and stretched out along the guide body 1, the sunshade sheet 9 is unfolded in the space of the outer wall corner C.
Furthermore, when folding the sunshade sheet 9, the electric motor 6 is operated in reverse to rotate the wire drum 7 in the closing direction, and the wire rope 8 is let out.

It will be stored by being folded and attached to C ₁ . As shown in FIG. 4, the sunshade sheet 9 is folded and stored on one side C1 of the outer wall corner C. Therefore, for example, a support arm with the sunshade sheet ₉ folded is placed at a position corresponding to the one side _C1 . 2. If a storage groove of considerable size is formed, the support arm 2 will be completely stored in the storage groove, making it even more inconspicuous, and will not detract from the external appearance of Building B.

In the above embodiment, the sunshade sheet is fan-shaped, but it may be a substantially square sunshade sheet. In this case, the support arms arranged radially with respect to the guide body are arranged in such a way that the length of the support arms becomes longer toward the intermediate position, and a substantially square sunshade sheet is stretched over the support arms. be. This makes it possible to cover almost the entire corner passage.

In addition, in the above example, the outer wall corner with known movable awnings on both sides is 180° or more (outer angle).
Although we have shown an example in which a movable corner awning is attached to a corner of an exterior wall, it is of course also applicable to a corner of 180° or less (inner angle). Further, in this embodiment, the movable awning has been described as a corner movable awning attached to an outer wall corner, but it is not limited to the outer wall corner, but can also be applied to a flat surface of the outer wall, that is, a flat side wall. In this case, the support arm is arranged in a 180° range, and a semicircular sunshade sheet whose diameter is parallel to the side wall is stretched over the support arm.

[Effect of idea]

Since this invention is configured as described above, the following effects can be obtained.

(a) The movable awning of this invention can be attached not only to the flat outer wall of a building but also to the corner outer wall so that the awning sheet can be unfolded and folded.

(b) The movable awning of this invention does not require fixed pillars, so it does not obstruct traffic.

C. In addition, since the awning sheet can be unfolded and folded, not only can sunlight and ventilation be obtained when desired, but when the movable awning is folded and stored, it is located along the outer wall, so not only does it not require a large amount of storage space. This prevents the exterior beauty of the building from being impaired.
