Description

Folding table

Technical field

The present invention relates to the one way of life articles for use, in particular, relate to a kind of folding table.

Background technology

The existing brace table that can stand after that can fold, folding is as desk, stool, chair, bed, stage in the market, because the frame mode of its leg is that intersecting axle be take as the horizontal direction cross-like in two planes, the stress of leg and the form of leg are not mated, so the pressure that table top can bear is smaller.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple, convenient, not the used time collapsible, with just bearing on less material table top than heavy articles, very solid brace table again, as table, stool, chair, bed, stage.

Folding table of the present invention, technical scheme is, comprise table top and supporting construction, folding table can be folded together, it is first face, second face, the 3rd face that supporting construction contains at least 3 faces, first face, second face contain leg, and the angle of first face, second face and horizontal plane is all 45 °～135 °, and the angle of the 3rd face and horizontal plane is 35 °～145 °; First face, second face, the 3rd face connect respectively, form three sides of triangular prism or three terrace with edges.

It is first face, second face, the 3rd face that supporting construction contains at least 3 faces, and first face, second face contain leg, and first face, second face, the 3rd face connect respectively, forms three sides of triangular prism or three terrace with edges; The benefit of this supporting construction is to be difficult for damaging by pressure under weight pressure, and the thrust lower platform body of other direction is not yielding.

Described table top is with supporting construction so that the two connected mode that can mutually rotate is connected, and supporting construction is provided with the center of gravity after making stage body folding, the device in the scope that the strong point surrounds when the folding rear support structure of stage body is standing state; Make the two its meaning of the connected mode that can mutually rotate refer to the device that hinged or sliding sleeve can slide and can rotate along the round bar of quilt cover, table top is once pushing away when avoiding duty, and table top preferably is connected without translation with supporting construction, hinged; Three sides all can be separately and table top hinged; The meaning that supporting construction is provided with the device in the center of gravity scope that the strong point surrounds when the folding rear support structure of stage body is standing state after making stage body folding is, supporting construction and the table top that for stage body, can mutually rotate after folding can be stood, and its strong point is larger than what do not need to stand; Stage body refers to the main body of folding table in the meaning of this patent, be not the main body that refers to separately table top.

Connected mode between first face, second face, the 3rd face is hinged or knot that can be undone by a pull or its combination; Hinged relatively good, do not need in use to find member, if the connection between three faces is all knot that can be undone by a pull, there is the trouble of looking for member; The purpose that hinged or knot that can be undone by a pull are set is for folding.

First face, second face are more drawn close to vertical direction, three terrace with edges or the triangular prism ability of object pressure of combating typhoon on face is stronger, first face, second face are more poorer to horizontal plane direction tilt the to combat typhoon ability of surface pressure, so, the angle of described first face, second face and horizontal plane is all 45 °～135 °, on three terrace with edges, the area of end face bottom surface differs less, more can optimize the ability of the anti-perpendicular pressure energy power of supporting construction and anti-other direction thrust, so the angle of described the 3rd face and horizontal plane is 35 °～145 °; If the angle of these three faces and horizontal plane is all 85 °～95 °, stressed better; Three faces are vertically stressed best.

Other face that contains leg under described table top, first face, second face, the 3rd face or platform, its form is plane or curved surface; Curved surface has cambered surface, folding face or compound curved surface; The definition of flexibility is rectangular rolled piece (type, rod, tubing) degree of crook in the longitudinal direction, and on every meter length, crooked action is every meter flexibility, and the action of every square metre of negative camber is every square of rice and flour flexibility; Flexibility bear more greatly along towards or the ability of axial compressive force or pulling force just less.

Described first face, second face, the 3rd face, table descend other face that contains leg, and its every square rice and flour flexibility preferably is less than 0.3, and every meter flexibility of bearing the table top pressure direction is less than 0.2; In order further to save material, every square of rice and flour flexibility can be less than 0.2, bears every meter flexibility that the object of putting on table top presses down direction and is less than 0.08.

The material of described stage body is bamboo and wood, metal, plastics, glass, fiberglass, stone material or wherein several combination.

Described first face, second face, the 3rd face, lower other face that contains leg of table contain polygon bar structure or panel or face above-below direction the width of narrow position be greater than 1/14th lath of platform height or truss or two intersection, middle hinged its end of bar fixedly sliding sleeve, sliding sleeve rotate or the structure of slip rotation along other two parallel bars of quilt cover, truss is that the straight-bar that mainly bears axial force connects into how much constant lattice load-carrying members on corresponding contact, and lath is the plate that length is far longer than width, and panel is the plate of difference within three times of length width, for the moment of flexure in anti-, the width of narrow position will be more preferably greater than 1/14th of table surface height for the face above-below direction, minimumly be greater than 5 centimetres, as lath or truss, as for two intersections, middle hinged its end of bar is sliding sleeve fixedly, sliding sleeve is along the structure that other two parallel bars rotate or slip is rotated of quilt cover, because its upper and lower width only has the radial dimension of a bar, very little, so, in face, bending resistance is very poor, preferably add the cross-articulation point of a cross bar across two bars, and cross bar is better away from more from the position of cross-articulation point, added cross bar two ends can connect respectively parallel bar, the mode connected can be used knot that can be undone by a pull, establish buckling device between table top in the time of also can be the bar upper end that becomes free-ended quilt cover with respect to table top and duty, polygonized structure does not have truss stability, so the turning of best polygonized structure is with metal reinforced.

Described second face, the 3rd face or integral face or at least two faces are with the face that only hinged or mode only knot that can be undone by a pull or its combination is formed by connecting, and two or more faces synthesize a face.

The quantity of described leg is more than 2,3,4 or 4; The form of described leg is member structure or lath or the bar of panel or cross bar kiss the earth; A panel of kiss the earth is also a leg.

Describedly be the face of 90 °～150 ° with the table top angle more than table top; Its meaning is the stage body with backrest, as chair or with backrest the bed, be preferably in the mesa edge setting and be connected with stage body.

In order not hinder stage body to be folded together, so be provided with the legs and feet device, be to be provided with the supporter fixing with leg in the position on the close ground of leg, as tripod or horizontal lath.Have folding after may not gather, buckling device need to be set.
