Abstract

The utility model relates to a folding support frame. The support frame of the existing folding table, folding bed, or folding chair is a stereo folding unit which is composed of X-shaped plane support units. The structure limits that the support plane of each stereo folding unit must be a square. The utility model adopts a rhombus hinge frame at two symmetrical and longitudinal lateral faces of the stereo folding unit. The rhombus hinge adopts the pairwise hinge of respective end parts of four support rods to form four hinge points in the centre position. Therefore, the support plane of each stereo folding unit can prolong the longitudinal length under the condition of the definite width.

Description

Folding support stand

The utility model belongs to a kind of supporting desktop, seat, bed surface of can be used for, and the bracing frame that can fold.

Existing is out on tours, the folding table of camping and designing, folding seat, the bracing frame of folding bed is normally with two equal length, the X-shaped support that the support bar of middle hinge (1) is formed is a flat-folded unit (see figure 1), make the corresponding termination of four sides and support bar head and the tail hinge respectively by four flat-folded unit of identical X-shaped again and be connected to form a three-dimensional spatial folding unit (referring to Fig. 2) of polygon shape in a zigzag, four sides, such spatial folding unit can be drawn into the very little column of volume in to central axis, be easy to carry, square-folded table bracing frame shown in Figure 2 promptly is made up of a spatial folding unit, rectangle Folding deck chair or bed then are made up of (referring to Fig. 8 two or more spatial foldings unit, Figure 10), each spatial folding unit top support surface of this structure all is restricted to and can only be square (referring to Fig. 5), so the folding desktop that is bracing frame with a spatial folding unit can only be a square, the rectangle chaise longue face and the bed surface that are bracing frame with two spatial folding unit also can only be that two squares are formed, when its width one timing, its unit longitudinal bracing point is also certain, if middle unit longitudinal bracing point just in time drops on the waist of bed surface or the thigh or the joint portion of seat, but can't adjust intermediate supports point position can for people's uncomfortable feeling.

The utility model aims to provide a kind of under the certain situation of width, but the folding support stand of proper extension supporting surface longitudinal length.

The technical scheme that realizes above-mentioned purpose is (referring to embodiment Fig. 4): the utility model is made up of one or several spatial folding unit, each spatial folding unit is to do four sides respectively by four flat-folded unit, the spatial folding unit that corresponding support bar termination, adjacent two sides hinge is connected to form polygon shape, the break position at its top is provided with the support fixation piece in order to fixed support surfaces, the flat-folded cellular construction of the transverse side (5) of two symmetries in spatial folding unit is identical, all for by two equal length, the X-shaped support that the support bar of intermediate point hinge is formed, it is characterized in that: the flat-folded unit of vertical side (6) of two symmetries for by four support bars respectively with 2 of ends separately hinge in twos mutually, thereby form the rhombus hinge frame (3) of four hinge points in the centre The shape support.

The set rhombus hinge frame (3) in the vertical side of the utility model can be under the certain situation of supporting surface transverse width, strengthen its fore-and-aft distance, thereby the supporting surface that has changed each spatial folding unit supports frame of existing folding support stand can only be foursquare present situation.

Embodiment 1 (seeing Fig. 4, Fig. 6):

This example is made up of a spatial folding unit, this spatial folding unit is done four sides respectively by four flat-folded unit and is made of the support bar 1 corresponding termination hinge of forming it, the flat-folded cellular construction of the transverse side 5 of two symmetries is identical, equal X-shaped supports for forming by the support bar of two equal length, intermediate point hinge, the flat-folded unit of vertical side 6 of two symmetries be after intersecting by four support bars respectively with 2 of ends separately hinge in twos mutually, thereby form the rhombus hinge frame 3 of four hinge points in the centre

The shape support, the corresponding termination hinge of adjacent side support bar connects, and forms three-dimensional polygon structure in a zigzag, and break position, top is provided with the support fixation piece, in order to fixing desktop 8.

Be provided with bracing piece 4 between the adjacent two intersection support bars of this example outside the rhombus hinge frame of vertical side, bracing piece one end is connected with a support bar hinge, the other end is enclosed within on another support bar with being slidingly matched, and be provided with retaining mechanism, can play the effect of stable support frame during locking, can fold up with whole bracing frame when unclamping retaining mechanism.

This example vertically set rhombus hinge frame in side has strengthened the fore-and-aft distance of spatial folding unit, so can make the folding table supporting surface 8 that adopts this bracing frame be rectangle.

Embodiment 2 (Fig. 7, Fig. 8)

This example is made up of two spatial folding unit, one is to make four lateral hinges by four flat-folded unit of X-shaped to form X-shaped spatial folding unit 13, another is that the corresponding transverse side of 12, two spatial folding unit, spatial folding unit of two the vertical side of symmetry band rhombus hinge frames is linked as one folding whole by the shared flat-folded unit of X-shaped 11 hinges.After being provided with the backrest support rods 9 of holding up, being fixed with supporting surface on it, the both sides, spatial folding unit transverse side of being with the rhombus hinge frame can support backrest.Hinge point on two spatial folding unit connecting portions is provided with handle support bar 10.

Make the deck chair (see figure 8) of bracing frame with present embodiment, under the certain situation of width, can add the distance of large back, make the intermediate supports point drop on the position of close shank, feel under the weather in order to avoid drop on thigh or joint part from face to intermediate supports point.

Embodiment 3 (Fig. 9, Figure 10)

This routine structure is substantially the same manner as Example 2, just the support bar at the two hinge point places, termination, spatial folding unit that are with the rhombus hinge frame extends obliquely upward, form to extend and raise support bar 16, make the bracing frame of folding bed with this example, extend and raise support bar and can play and raise bed surface and do the effect that pillow supports.Owing to strengthened the distance of head, feel uncomfortable so can avoid first strong point to fall the human body waist simultaneously to first strong point.
