Folding tent frame

The present invention relates to a folding tent frame, and more specifically, when installed, it is possible to secure a certain height and area, and when assembled after dismantling, it has a size that can be loaded into the trunk of a passenger car, and thus the folding tent frame is easy to carry. It is about.

In general, tents are used to cover the sunlight or simply to secure a certain enclosed space.

Due to its characteristics, such a tent is the first requirement that it is easily installed and dismantled so that it is easy to use. To this end, folding tents have been developed and widely used.

The folding tent is pulled out by pulling the top column or opening the support pillar, and the tent is folded and folded when the tower pillar is pushed or the support pillar is folded.

In general, the folding tent frame is installed on each of the four support pillars at positions corresponding to the vertices of the quadrangle, and two sides forming the four sides connecting the support pillars and the cross shape connecting the centers of the four sides. It consists of a folding member which is an X-shaped structure of an integral multiple of 2, and a tower column which is assembled at the center of the cross and slides up and down according to the folding operation of the folding member.

An example of a folding tent frame according to the prior art is shown in FIG. 1. This example is a case where there are two folding members between each support pillar.

Referring to the drawings, the four support pillars 1 are connected to four surfaces consisting of two peripheral folding members 3, and the peripheral folding members 3 forming the four surfaces are connected to two surfaces forming a cross shape. The two surfaces are also composed of two central folding members (5).

The peripheral and the central folding member (3, 5) is composed of two rods, there is a rotating portion 7 is rotatably coupled to the center portion can be folded and unfolded like scissors.

The two peripheral folding members 3 forming the four sides are coupled so that two ends of the X-shape adjacent to each other can be rotated with each other, and the upper end of the two X-shapes on the side connected to the support pillar 1 It is fixed to the upper end of the support pillar (1) is coupled to be rotated and the lower end is coupled to be able to rotate to the movable block (9) sliding up and down along the support pillar (1).

The two sides formed by the cross of the center is composed of two central folding member (5), the two ends of the side connected to the peripheral folding member (3) of the X-shaped is fixed to both ends of the connecting portion of the peripheral folding member (3) Assembled so that the center folding member (5) of the X-shape is coupled to each other, the upper end is rotatably coupled to the top block 11 that slides up and down with respect to the column (13), The stage is fixed to the tower column 13 and is assembled to be rotatable. Therefore, four central folding members 5 are assembled in the top block 11 and the top pillar 13 at intervals of 90 degrees.

The top pillar 13 has four central folding members 5 rotatably assembled at the bottom thereof, and the top block 11 can slide up and down according to the folding motion of the peripheral and central folding members 3 and 5. Is fitted inside).

Referring to the operation of the conventional folding tent frame having the configuration as described above are as follows.

When the user grasps the four support pillars (1) and open the peripheral folding member (3) connecting the support pillars (1) is opened by the letter X to expand the tent frame. At this time, as the tent frame is unfolded, the central folding member 5 is also opened by the letter X, and the tower column 13 in the center is raised upward.

However, such a folding tent has a problem that the length of the tent when folded is 1.25 ~ 1.75m in order to have a length of 2.5 ~ 3.5m each when installed, there is a problem that does not enter the trunk of the car. In other words, the installation and dismantling of the tent is convenient, but there is a problem that it is difficult to transport it to the place of use because it cannot be loaded in the trunk of a passenger car.

In order to determine the cause of the above problems, the relationship between the dimensions of the folding tent frame is as follows.

First, the length of the support pillar 1 of the folding tent frame is referred to as L, and the length of the bars of the peripheral and central folding members 3 and 5 is A, and the bars of the peripheral and central folding members 3 and 5 are When the angle formed with the horizontal plane is θ, the length W in the vertical direction of the peripheral and central folding members 3 and 5 and the rising height P of the top pillar 13 change as the folding tent frame is unfolded. It can be obtained from the following equation.

W = Asinθ ---- (1)

P = L-W ---- (2)

In addition, the length (S) of the tent frame horizontal or vertical

S = Acosθ * n ----- (3)

Becomes N is the number of connections connected in the horizontal or vertical direction of the peripheral and central folding member (3,5). At this time, to ensure the stability of the central and peripheral folding members (3,5) W should be at least 10cm.

In general, the specifications of the folding tent is widely used when the tent is stretched, the length and width is about 2.5 ~ 3.5m, the height is more than 2.2m. In addition, in order for the rainwater accumulated on the roof of the tent to flow down easily, the height of the tower column should be more than 0.8m, and the maximum length should be less than 1.25m when the tent frame is folded so that it can be loaded into the trunk of a passenger car. Condition is added.

In order to satisfy the above conditions, the length of L and A must be less than 1.25m. Therefore, when the folding tent frame as in the above example of n = 2, the length of the horizontal / vertical becomes less than 2.5 m when all the tent frames are unfolded so that the above conditions are not satisfied.

When n = 4, it can be 2.5 m or more, but in order to have a length of 3.5 m or less, P becomes 0.8 m or less.

That is, the folding tent frame according to the prior art has a length of 2.5m to 3.5m when the tent frame is unfolded as described above, and the height of the tower pillar is 0.8m or more, and the longest length when the tent frame is folded There was a problem that can not satisfy the conditions that can be loaded in the trunk of the passenger car is less than 1.25m.

The present invention was devised to solve the above problems, by connecting the central folding member and the top pillar with a Weiza (Y) type of lifting member, when the folded tent frame is unfolded 2.5m to 3.5 Its purpose is to provide a folding tent frame with a length of m and the height of the tower column is more than 0.8m, and when the tent frame is folded, the longest length is 1.25m or less.
