Description

[Detailed explanation of the invention] [Industrial application field] This invention is a foldable tent, more specifically, the roof frame can be folded in half at the ridge part to make it flat, and it can be folded according to the usage conditions. The present invention relates to a multi-purpose tent that can be assembled to the required width and length.

[Conventional technology and issues to be solved]

House-shaped tents that have been commonly used in the past have a frame assembled by connecting pipes and a tent cloth attached to this frame, so the structure is complex and requires time and effort to assemble and dismantle.
If the frame constituent members are completely separated, there is a problem that management of the members becomes troublesome and powder loss is likely to occur.

Further, since conventional house-shaped tents can only be assembled with a specific planar size, it is difficult to obtain a tent with an optimal size that corresponds to the conditions of use.

This idea was made to solve the above problems, and by integrating the frame components, assembly and disassembly can be easily performed, and the frame can be folded flat when disassembled. It is an object of the present invention to provide a folding tent that can be assembled to a required length without causing any loss of powder from component parts.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention connects a pair of upper main frames formed in a rectangular frame shape so that they can be folded in half at both ends of the ridge part, and connects the horizontal rods on both gable sides of both upper main frames. A parallelogram-shaped link structure is provided at the bottom of the frame that includes the gable side beam and also shares a center link whose upper end is pivotally connected to the pivot connecting part of both upper main frames. A roof frame that can be folded upward from the eave-side down position about a stop point, and a column frame that is arranged opposite to the lower part of the eave-side portion of both upper main frames of the roof frame and whose upper end is attached to a link structure. and a roof covering member installed to cover the upper surface of the roof frame, and link structures on both gable sides of both upper main frames of the roof frame, with gable side cross beams of both upper main frames, and both upper main frames. A common center link whose upper end is pivoted to the ridge pivot connection part of the frame and has elongated holes in the vertical and longitudinal directions; A pair of support links are connected so as to be movable up and down along the elongated hole, and the upper ends are pivotally connected to the gable side cross bars of the corresponding upper main frames; A column frame fixing link whose upper end is pivotally fixed to the eave side end and is swingable along the direction from the ridge to the eaves; The inner end is pivotally connected to the lower end of the center link, the outer end of the eave side is pivotally connected to the lower end of the corresponding column frame fixing link with this column frame fixing link parallel to the center link, and the gable side The column frame is formed by a pair of lower inclined crosspieces on both sides arranged parallel to the horizontal rods, and a tension spring for opening and closing stretched between the lower inclined crosspieces on both sides, and the column frame is fixed to the column frame in the link structure. The roof frame is fixedly attached to the roof link with its vertical direction aligned with the length direction of the link, and joints for sequentially connecting the roof frame to the gable side cross beams of both upper main frames of the roof frame are provided. This configuration is adopted.

[Effect]

When the axis of the spring is located below the pivot points of the center link and the lower sloped crosspiece, the roof frame
The upper main frames on both sides are in an extended state downward to the eaves, the support links maintain the extended state of both upper main frames, and the column frames on both sides stand up facing each other.

A house-shaped tent is completed by assembling the above-mentioned frames to the required length by sequentially connecting them with joints at the ends, and attaching a covering member to the roof frame of each frame.

Also, when disassembling and folding, all you need to do is push up both eaves sides of the roof frame and pass the axis of the spring above the pivot points of the center link and lower inclined crosspiece, and the upper main frames on both sides are connected to the support links. rises along the center link, folding in half around the ridge and overlapping, and the pillar frames on both sides overlap with the roof frame in between, making the whole structure flat.
