Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a folding frame applicable to tables, chairs, stepladders, temporary frames for stages, podiums, etc., tent frames, etc. It is.

(Conventional technology) Conventionally, when necessary, a three-dimensional framework was used to perform seven predetermined functions.
Various structures have been proposed as frames that can be folded and stored when not needed, but they lack structural reliability, and
There were problems such as complicated assembly operations.

(Means for Solving the Problems) The present invention was proposed to solve these problems, and consists of a pair of compressed material bases each forming a triangular truss on each side of opposing planar structural members. Relating to a folding frame characterized in that the ends are joined with pins, the vertices of opposing triangular trusses are joined with pins, and the apex pin joints of each of the opposing triangular trusses are connected with a tension member. It is something.

(Function) and (Effects of the Invention) As described above, in the frame according to the present invention, the base ends of the pair of compressed materials constituting the triangular truss are pinned on each side of the planar structural members made of opposing plates, frame materials, etc. The vertices of the opposing triangular trusses that are joined to the wing on both sides are pin-joined in the middle of the opposing planar structural members, and the respective apex bin joints are connected with tension members. By configuring the tension member from an expandable member or a removable member, each compression member constituting the triangular truss can be rotated around the pin joint portion of each triangular truss [by folding]. , the frame of the present invention is folded into a plane.

When using the frame of the present invention, the triangular trusses are rotated and expanded around the pin joints of the triangular trusses, thereby connecting the opposing plate constituent members with the triangular truss, A frame is assembled in which the pin joints at the tops of opposing triangular trusses are connected using tension members.The frame is supported by each group of upper and lower triangular trusses, and the outward expansion of each triangular truss due to compressive force is prevented. The tension members connecting the apex pin joints of the upper and lower trusses create a structurally stable frame.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(1) (1') are upper and lower plate constituent members made of a rectangular frame, and a pair of compressed members (2) (2') forming a triangular truss are placed near both ends of each side of each member (IXI'). The proximal end has a pin (
3) (3'), the vertices of the opposing triangular trusses are joined by pins (4), and a telescopic tensile member ( 5) are connected.

Since the illustrated embodiment is constructed as described above, when the upper plane component (1) is pulled up from the folded state shown in FIG. Pins (31) are attached to the base ends of the opposing sides on the opposite sides. The triangular trusses are located on the same plane, and the pins (4) at opposite ends of both trusses reach the recursion point. (See Figure 3) When this state is exceeded, the opposing triangular trusses expand outward. At this time, the tension member (5) connecting between the pins (4) at the opposite ends of the opposing triangular trusses is tensioned, and each triangular truss is held in the deployed position. The required frame is assembled using tension members that can be expanded and contracted like a truss. (See Figure 4) If not needed, each triangular truss can be folded inward by the reverse operation as shown in Figure 1. It can be folded onto one plane.

Figures 5 to 8 show the plate components (1) during assembly and folding.
) (One shows the relationship between the compressive material (21 (2')) and the tensile material (5).

According to the above embodiment, although the height h of one unit cannot be larger than twice the radius of the plane, there is an advantage that the tensile material can be stored continuously.

FIG. 9 shows another embodiment of the present invention, in which a compressed material is joined at the base end with a pin (31 (3')) to each side of the upper and lower planar structural members (1) (1') consisting of a rectangular frame. +21 (21, (
2') (2') Connect the opposing vertices of the upper and lower triangular trusses with pins (4), and connect one end of the tension member (5) to the apex of the upper triangular truss. Connect the opposite vertices of the truss with pins (4J),
The other end of the tensile member (5) is connected to the pin (4) portions at the opposite vertices of adjacent upper and lower triangular trusses to assemble the frame.

Also, when folding, the connection between the other end of the tension member (5) and the pin (4) portion is released, and each triangular truss planar component (1) (1
It is something that expands outside of the world.

According to the above embodiment, the height of one unit can be set freely compared to the inward folding type frame shown in FIGS. 1 to 4, but the tension member (5) must be removed when storing.

In each of the above embodiments, the shape of the plane component can be freely selected from polygons to circles, and in addition to frame-shaped members, it may also be composed of plates, and by stacking units, the height of the entire structure can be increased. can be made even higher.

FIGS. 11 to 14 show the case where the present invention is applied to tape/I/VC, and the horizontally bent ends of a pair of compressed material eel 0 configured as a triangular truss are attached to the sheath pipe α2 fixed to the deck (11). (13α 13 are rotatably connected to each other by a sheath tube α4), and a tensile member insertion ring (le) is disposed in the sheath tube α4).

In addition, each compression member (13'X13') of the adjacent lower triangular truss
).

(Horizontal frame material that connects 13 pieces (13'AX13
The sheath tube α at both ends of the plate αη is rotatably fitted between 'A), and the lower plane component opposite to the deck aυ which constitutes the upper plane component is formed by the group of horizontal frame members (13'A). It is configured.

Although the present invention has been described above with reference to embodiments, the present invention is of course not limited to these embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
