Abstract

PROBLEM TO BE SOLVED: To solve the problem of a conventional canopy structural body by terminating the center side end sections of roof support members in the middle into a free state without concentrating them at the center section of a roof. SOLUTION: This folding canopy structural body comprises a scissors assembly rotatably connected with two bars in an X-shape and made foldable into a pantograph shape, the roof support members, and poles. The poles, scissors assembly, and roof support members are connected together by fixed brackets fixed at the upper sections of the poles and slide brackets inserted slidably at the middle of the poles to form the folding canopy structural body. The center side end sections of the roof support members are terminated in the middle without being concentrated at the center section of the roof.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a foldable canopy structure constituting a framework such as a tent and a sunshade.

[0002]

2. Description of the Related Art Conventionally, using a scissor assembly in which two bars are rotatably connected in an X-shape by a connecting portion and can be freely folded in a pantograph shape, a tent, a sunshade and the like can be freely folded. It is known to form a simple canopy structure, and it is disclosed in, for example, Japanese Patent No. 2625255. Such a foldable canopy structure,
When unfolded, it can cover a sufficiently large area,
Also, when folded, it will be small enough in size and shape,
Because it can be carried in a desired bag, it is widely used. The strut, scissor assembly and roof support member are interconnected by a frame connection bracket that allows relative rotation, one of the brackets being fixed to the upper end of the strut and the other being along the strut. The scissor assembly is connected between the fixed bracket and the sliding bracket so that bending and extension of the scissor assembly can be achieved. And
The roof support member has a structure in which one end is connected to a support, and the other end is rotatably connected to a roof center support at the center of the roof.

[0003] However, such a canopy structure has a problem that the roof support member moves upward while deploying the roof sheet when the support is moved sideways through the scissor assembly. Since the load of the member is added and a large moment is applied to the slide bracket, the deployment operation of the canopy structure is made heavy. The canopy structure, in which the end of the roof support member is concentrated in the center of the canopy, which is a tent or a sunshade, and is rotatably connected to the roof center support column, is a column in which the roof center support column rises vertically. On the other hand, since the roof support member is connected from a horizontal direction substantially orthogonal to the roof center support column, a problem is likely to occur in the rotation at the connection portion, and the roof may not be folded.
In addition, since the sheet-shaped roof body is supported by the support pillars that are vertically erected, there is a risk that the roof body is broken through by the support pillars.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a conventional canopy structure in which a center end of a roof support member is terminated on the way to a free state without being concentrated on the center of the roof. It is intended to solve the problem.

[0005]

In order to solve the above-mentioned problems, the present invention adopts a scissor assembly in which two bars are rotatably connected in an X-shape so as to be foldable in a pantograph shape. , The roof, the scissor assembly, and the roof support member are connected to each other by a fixed bracket fixed to an upper portion of the support column and a slide bracket slidably inserted in the middle of the support column. In the flexible canopy structure, the center side end of the roof support member is terminated on the way without being concentrated on the center of the roof, and is free.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. With reference to the drawings, (1) shows a canopy structure according to the present invention, in which a plurality of columns (2) which stand vertically and a plurality of scissor assemblies () which connect the columns (2) foldably. 3) and roof support members (4)
A roof sheet having weather resistance and waterproofness is stretched on the upper surface of the assembled canopy structure, and the roof sheet is foldable in accordance with the folding of the canopy structure. In the illustrated embodiment, the canopy structure (1) is formed in a substantially square shape having columns (2) at four corners, and a roof support member is provided at the upper end of each column.
Although the structure (4) is connected, it goes without saying that the roof support member (4) may be connected only to the upper ends of two opposing columns as shown in FIG. The scissor assembly (3) is composed of two bars rotatably connected to each other in an X-shape at the center so as to be bent and stretched in a pantograph shape, and one of the free ends of each bar is a column (2). The other end is fixedly connected to the upper end, and the other end is slidably connected vertically along the column. The roof support member (4) is also connected to the support so as to shift from the roof support position to the non-support position in accordance with the bending and extension of the scissor assembly (3). When the scissor assembly (3) is extended, the struts (2) move laterally away from the folded position in accordance with the extension, and the roof support member (4) shifts to the roof support position. Then, the canopy structure (1) is deployed, and at the same time, the roof sheet is deployed so as to cover the upper surface of the canopy structure (1).

The present invention is characterized in that, in such a canopy structure, the roof support member (4) is terminated at an intermediate position in a free state without being concentrated and connected to the center of the roof. Referring to FIGS. 3 and 4, the roof support member (4) is made of one bar, and one end is rotatably connected to a fixing bracket (5) fixed to the upper part of the support (2). The end is formed to have a length shorter than the length of the roof, and terminates in the middle of the roof to be free. One end of the staff member (6) is rotatably pivotally mounted in the middle of the roof support member (4), and the other end of the staff member (6) slides the scissor assembly (3) to the support (2). Slide bracket for free connection
When the canopy structure (1) is unfolded from the folded state as described above, the roof support member (4) is moved to the roof support position. By terminating the roof support member (4) halfway without concentrating at the center of the roof, the structure for connecting the roof support member (4) at the center becomes unnecessary, and the configuration of the canopy structure is simplified, and the cost is reduced. In addition to providing the roof support member, there is no need to worry about breaking through the center of the roof sheet with the roof support member.

[0008]

According to the present invention, since the roof support member is terminated in the middle of the roof without being concentratedly connected to the central portion of the roof and is in a free state, the weight of the roof support member is reduced and the slide bracket is reduced. Of the canopy structure, the canopy structure can be easily started up, the structure of the canopy structure can be simplified and provided at a low cost, and the roof support member is connected to the central portion in a concentrated manner. In such a case, there is no possibility that the roof sheet is broken through by the connecting portion. In addition, since the roof support frames are configured independently,
There is an advantage that the setting of the length, height or number of frames can be set freely, and the degree of freedom in designing the roof shape is increased.
