However, the former is seated on the ground surface due to its own weight, and if necessary, the seat is only fixed to the ground surface by the anchor, so when a large external force such as strong wind is applied. There was a risk of falling.
On the other hand, the latter has a base, which functions to some extent as a weight (weight), but was not originally designed to function as a weight. There was a risk of falling when external force was applied.

  The present invention was devised in view of the above-mentioned problems, and was devised to solve this problem. The subject of the present invention is that there is no risk of falling even if a large external force such as a strong wind acts. Provided tent frames.

  The tent frame of the present invention is basically provided with an appropriate number of main frames arranged at predetermined intervals in the front-rear direction, and provided at the lower portion of the main frames so that the height can be adjusted and grounded to the ground plane. A seat body, a weight body that has a predetermined weight and is grounded to a ground contact surface located between adjacent main body bodies, and a rope that connects the weight body and the upper part of the main body body. There is a feature in doing.

The main body is established on the seat while the seat is grounded to the ground surface. The weight body is grounded to the ground contact surface located between the adjacent main bone bodies before and after, and the weight body and the upper part of the main bone body are connected by a rope.
A weight with a predetermined weight is provided and the upper part of the main frame is connected to the upper part of the main frame by means of a rope. Even if a large external force such as strong wind acts on the tent frame, it falls or skids. There is nothing to do.
When the seat is adjusted and moved with respect to the main bone body, the height of the main bone body can be adjusted with respect to the ground contact surface.
Since the weight body is provided between the main bone bodies before and after adjacent to each other, and the cord is provided between the weight body and the upper portion of the main bone body, these do not disturb. As a result, the tent frame can be used effectively.

  An anchor that fixes the seat to the ground surface, a second ridge that connects the anchor and the upper part of the main frame, and a second ridge that is provided on the seat and goes from the anchor to the upper part of the main frame. It is preferable to provide a guide body that changes direction to a substantially vertical direction. In this way, the establishment of the main frame body is secured by the second rope, and the seat body is provided with a guide body, so the anchor is always pulled horizontally by the second rope and comes out. There is no worry.

  The second rope may connect a part of the seat body and the upper part of the main bone body. In this way, one end of the second rope is not fastened to the anchor, so there is no fear that it will come off.

  It is preferable that the rope and the second rope are provided with tension adjusting means for adjusting the tension. In this way, the tension of the rope and the second rope can be easily changed, so that the main body can be established quickly and appropriately.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view in which a part of the tent frame of the present invention is omitted. FIG. 2 is a side view of FIG. FIG. 3 is a cross-sectional plan view of FIG. FIG. 4 is a main part front view showing an attached state of the second rope. FIG. 5 is a view similar to FIG. 4 showing another attached state of the second rope. In the following description, the front-rear direction refers to the depth direction of the tent frame (vertical direction in FIG. 3), and the left-right direction refers to the width direction of the tent frame (left-right direction in FIG. 3). I will say.

The main part of the tent frame 1 is composed of a main body 2, a seat body 3, a weight body 4, and a rope 5, and is applied to a tent house.
The tent house is composed of a tent frame 1 installed on the ground contact surface A and a tent sheet (film body) stretched outside the tent frame 1 (not shown).
The ground surface A is paved with concrete, asphalt or the like, and is relatively strong and smooth.

The main bone body 2 is an appropriate number arranged in the front-rear direction at a predetermined interval. In this example, the main body 2 is detachably connected to an upright column 6 and an upper portion thereof, and extends obliquely upward therefrom. And a roof bone 7.
The support column 6 includes left and right vertical pipes 8 and an appropriate number of cross members 9 and an appropriate number of struts 10 that connect them.
The roof bone 7 includes upper and lower oblique tubes 11, and an appropriate number of vertical tubes 12 and an appropriate number of myotubes 13 that connect them.
Thus, an appropriate number of main frames 2 are arranged at predetermined intervals in the front-rear direction, and an appropriate number of connections are provided between main frames 2 adjacent to each other in the front-rear direction. A body (muscle or girder) is detachably provided. Therefore, the tent frame 1 includes this connection body.

The seat body 3 is provided at the lower portion of the main bone body 2 so that the height can be adjusted. In this example, the seat body 3 is a screw base (jack base) and is provided at the lower portion of the support 6 of the main bone body 2. Left and right seat plates 14 each having a substantially square planar shape, a screw rod 15 that is implanted in the seat plate 14 and is removably inserted into the vertical tube 8 of the column 6, and screws A handle nut 16 that is joined to the lower surface of the vertical tube 8 of the column 6, a retaining bolt 17 that is screwed to the vertical tube 8 of the column 6 to prevent the screw rod 15, and four corners of the seat plate 14. And a mounting hole 18 drilled in.
Thus, the seat plate 14 is fixed to the ground plane A by inserting anchors 19 such as piles and anchor bolts into the mounting holes 18 and driving them into the ground plane A.

  The weight body 4 is grounded to the ground contact surface A located between the adjacent main bone bodies 2 before and after and has a predetermined weight. In this example, the weight body 4 has a rectangular parallelepiped shape and has an installation area of each main bone body 2. The outer shell 20 is made of metal and has a box shape, concrete 21 filled therein, and an appropriate number (three) of eyebolts attached to the upper surface of the outer shell 20. The hanging tool 22 is provided.

  The rope 5 connects the weight body 4 and the upper part of the main bone body 2. In this example, the wire 5 is a wire rope, one end of which is fastened to the hanging tool 22 of the weight body 4, and the other The end is fastened to a fastening tool 23 such as an eyebolt provided at the base end of the roof bone 7 of the main frame 2.

  Thus, in the tent frame 1, when the weight body 4 is not installed in the vicinity of the main bone body 2 or cannot be installed, the anchor for fixing the seat body 3 to the grounding surface A as shown in FIG. 19, the second rope 24 connecting the anchor 19 and the upper part of the main bone body 2, and the second rope 24 provided on the seat body 3 toward the upper part of the main bone body 2 from the anchor 19. And a guide body 25 that changes direction in a substantially vertical direction. Alternatively, as shown in FIG. 5, an anchor 19 that fixes the seat to the grounding surface, a second rope 24 that connects a part of the seat 3 and the upper part of the main frame 2, and a seat 3 are provided. Then, a guide body 25 is provided for changing the direction of the second rope 24 from a part of the seat body 3 toward the upper portion of the main body 2 in a substantially vertical direction through a substantially horizontal direction.

  The anchors 19 are provided on the left and right in response to the seat body 3. In FIG. 4, the anchors 19 are stakes each having an annular head, and are inserted into the mounting holes 18 positioned on the left and right outer sides of the both seat bodies 3. In addition, the right and left ones are placed in the ground contact surface A with an inclination of a predetermined angle (approximately 12 degrees) so as to be directed to the left and right as they go downward, that is, substantially V-shaped. In FIG. 5, the anchor bolt is used.

  The second rope 24 is a wire rope similarly to the rope 5, and in FIG. 4, one end is inserted through the annular head of the anchor 19 and is fastened, and the other end is the main body 2. It is fastened to a fastening tool (not shown) such as an eyebolt provided at the base end of the roof bone 7. In FIG. 5, one end is suspended and fastened to the screw rod 15 of the seat body 3, and the other end is a fastening tool (such as an eye bolt) provided at the base end portion of the roof bone 7 of the main body 2. (Not shown).

  The guide body 25 uses a metal fitting commonly referred to as “Bellakan” or “Virakan”, and includes a ring having a substantially flat D shape and a mounting plate that is folded in two to support the ring rotatably. . The guide body 25 is fixed to the corner portion of the seat plate 14 of the seat body 3 located on the opposite side of the anchor 19 by welding or the like, and the ring rotates up and down around the horizontal axis with respect to the mounting plate. It can be done.

Next, the operation will be described based on such a configuration.
The seat body 3 is grounded to the ground surface A, and the main bone body 2 is established on the seat body 3. The weight body 4 is grounded to the ground contact surface A located between the adjacent main bone bodies 2 before and after, and the weight body 3 and the upper part of the main bone body 2 are connected by the rope 5.
Since the weight body 4 having a predetermined weight is provided and the upper portion of the main bone body 2 is connected to the upper portion of the main frame body 2 by the rope 5, even if a large external force such as a strong wind acts on the tent frame 1, it falls down. Or skidding.

When the retaining bolt 17 of the seat body 3 is loosened and the retaining bolt 17 is tightened again after rotating the handle nut 16, the height of the main body 2 can be adjusted with respect to the ground plane A. For this reason, the heights of the main bone bodies 2 arranged in the depth direction (front-rear direction) of the tent frame 1 can be easily aligned.
The weight body 4 is provided between the main body 2 and the adjacent main body 2, and the rope 5 is provided between the weight body 4 and the upper part of the main body 2. However, these do not get in the way because they do not protrude greatly from the installation area of the main body 2. As a result, the inside of the tent frame 1 can be used effectively.

When the weight 4 is not installed in the vicinity of the main body 2 or when it cannot be installed, one end is fixed to the anchor 19 or the screw rod 15 of the seat body 3 and the other end of the main body 2 is fixed. Since the second rope 24 fastened to the proximal end portion of the roof bone 7 is provided, the establishment of the main frame body 2 is ensured.
Since the guide body 25 is provided in the seat body 3, there is no fear that the anchor 19 or the screw rod 15 of the seat body 3 is always pulled horizontally by the second rope 24 and pulled out.

In the above example, the main frame body 2 is such that the column 6 and the roof bone 7 are detachably connected. However, the main frame body 2 is not limited to this, and for example, these may be integrated.
In the previous example, the jack base is used as the seat body 3, but the seat body 3 is not limited to this, and may have another structure, for example.
The rope 5 and the second rope 24 are wire ropes in the previous example, but are not limited thereto, and may be, for example, a chain.
In the previous example, the rope 5 and the second rope 24 are interposed between the weight body 4 and the base end portion of the roof bone 7 of the main frame body 2. And the upper part of the support 6 of the main bone body 2 may be interposed.
In the previous example, the rope 5 and the second rope 24 are not provided with a means for adjusting the tension, but are not limited thereto, and may be provided with a tension adjusting means such as a turnbuckle. The tension adjusting means can be interposed, for example, in the middle of the rope or between the rope and the weight body.
In the previous example, the guide body 25 uses a metal fitting commonly referred to as beracan or vilacan. However, the guide body 25 is not limited thereto, and a pulley or the like may be used, for example.
