All components can effectively bear load, and intensity of the components is maximally played.

Description

A kind of travel(l)ing rest

One, technical field

The utility model relates to a kind of support, particularly can change the travel(l)ing rest of form.

Two, background technique

In people's production and life, can use many supports, as tent, umbrella, scaffold, bridge, power transmission tower frame or the like.Can stent types has a variety of, change by its form, can be divided into fixed support and travel(l)ing rest.Fixed support such as iron and steel truss, pylon etc.; Travel(l)ing rest such as common tent, foldable chair etc.Can amount to stool, table, chair that travel(l)ing rest has unidirectional-folding, the multidirectional umbrella of amounting to, German chair (being commonly called as chair for fishing) and Chinese classical drum bookshelf etc. are arranged.Travel(l)ing rest has brought many convenience to people's life.All there is compensation device to assist folding and unfolding but these supports are shut at radio, makes comparatively loaded down with trivial detailsly, make the transition piece of angle distortion with 8 hoof pieces, make trouble, and easily cause the damage part, made a discount whole working life as German chair.China's drum bookshelf is deposited the generation use and has been exceeded thousand, and it is with rope 6 fine bamboo rod colligations to be become A-frame, and the slack and undisciplined superimposed occupy-place difficult point that solves the bamboo bar with rope is unsuitable for extended use.

Three, summary of the invention

The purpose of this utility model provides a kind of travel(l)ing rest simple in structure, easy to use.

The technical solution adopted in the utility model is: travel(l)ing rest is made of the identical pillar rod hinge connection identical with shape of several shapes, pillar is identical with connecting rod quantity, be straight-bar, three hinges in upper, middle and lower are all arranged on each pillar and the connecting rod, the last hinge of pillar and the last hinge of connecting rod are hinged, the middle hinge of pillar and the middle hinge of connecting rod are hinged, the following hinge of pillar and the following hinge of connecting rod are hinged, each pillar respectively with three different rod hinge connections, propping up that each connecting rod is also different with three respectively is column articulated, and all pillars constitute ring-type with connecting rod integral and are connected.

The utility model is the basic element of character with the straight-bar, since the upper, middle and lower hinge of each parts all with different miscellaneous part connections, and all parts finally need be enclosed a ring-type, so, the hinge center line of three hinges on each parts forms several angle between each hinge all not in the same way.Like this, when support carried out folding and unfolding, each parts was also carrying out horizontal rotation when vertically rising and falling.Simultaneously and since each hinge not in the same way, when support was decontroled several angle, upper and lower hinge had also played position-limiting action, made the maximum opening angle of travel(l)ing rest determine, and needn't increase limit stoper.Simultaneously, the multiple variant of this travel(l)ing rest can bring convenience to people, fast, saves benefits such as material and workload.

The utility model is simple in structure, and used member is minimum, hinge few (common four edge breaks close the hinge of support all more than 20, and the utility model is only used 12), not using compensation device.Closing up becomes a branch ofly, easy to carry and store, forms firm support during relieving, can make multiple uses such as table, chair, stool.As travel(l)ing rest, can move a post (bar) and full frame interlock, all parts are all effectively shared load, make the intensity of parts be able to maximum performance.

The utility model not only can be used on the furniture of daily life, also can use on engineering structure.During relieving, all pillars and connecting rod are not vertical direction and substantially horizontal, as the outdoor large support, can reduce windage and sleet and coagulate extension.As with the utility model as elementary cell, a plurality of unit vertically make up, and can become large-scale fixed gantry by rivet welding, are used for engineering constructions such as electric transmission line.Elementary cell can be prefabricated in the factory, and assembled on site can be saved lot of materials and man-hour, improves efficiency of construction.

Five, embodiment

The utility model adopts the pillar 1 be the straight-bar shape and connecting rod 2 formation that is hinged, and is generally round bar.Pillar 1 is used for supporting, and comparatively sturdy, also longer, 2 interconnect functions of connecting rod can be thin slightly, and is short.The position, upper, middle and lower of three hinges 3 of each pillar 1 is identical, and the position, upper, middle and lower of three hinges 3 of each connecting rod 2 is also identical.Can be constituted in twos by pillar and connecting rod during making and cut fork, it is upper and lower again respectively with adjacent to cut fork hinged that each cuts fork, cuts fork by several at last and enclose ring-type.

When the quantity of pillar 1 and connecting rod 2 is three, can constitute triangular supports, the axis direction of three hinges 3 in upper, middle and lower on each pillar 1 and the connecting rod 2 differs 60 ° successively, amounts to 9 hinges 3; When the quantity of pillar 1 and connecting rod 2 is four, then constitute the quadrilateral support, the axis direction of three hinges 3 in upper, middle and lower on each pillar 1 and the connecting rod 2 differs 45 ° successively, amounts to 12 hinges 3.Equally, pillar 1 increases with the reasonable quantity of connecting rod 2, can constitute polygon-shaped travel(l)ing rest, and hinge also increases thereupon.All these hinges axially be centripetal direction, and each hinge changes the direction in length and breadth of support and all works.

The position difference of three hinges 3 on the pillar 1, the form when formed support struts is also different, and pillar 1 can be obtained multiple variant with the quantity of connecting rod 2 and the various combination of hinge 3 positions.If upper and lower hinge is near the pillar two ends, connecting rod 2 is isometric substantially with pillar 1, is flush shape up and down when then support struts; When three hinges 3 all at pillar 1 first half, and go up, middle hinge spacing is little, in, the hinge spacing is big down, is pyramid shape when then support struts; When three hinges 3 during, be the wasp waist shape when then support struts all near the intermediate portion of pillar 1; When last hinge is positioned at pillar 1 upper end, following hinge is positioned at pillar 1 middle and lower part, is asymmetrical shape up and down after then support struts.
