A folding bench which has a folding fixed structure is provided to reduce the volume of the folding bench, which makes the collection and the transportation easy without occupying large space.

Description

Folding bench

Technical field:

The utility model relates to a kind of Folding bench, and particularly a kind of have a Folding bench of amounting to fixed structure.

Background technology:

The use of Folding bench mostly is provisional greatly or use in the indefinite form place, comprises a seat board in its structure; Two are locked in the pin joint seat of this seat board bottom, side frames, and wherein arbitrary this bogie side frame has first foot rest and second foot rest, and the chair pin is the structure that is fixed as one, can't folding, very inconvenience of therefore collection, transportation, and quite take up space.

The utility model content

The chair pin that the utility model will solve existing Folding bench can't fold and cause transporting collection and be difficult for and take technical problem than large space, a kind of Folding bench of amounting to fixed structure that has is provided, in order to reduction Folding bench volume, make it be easy to collection and carrying, can not occupy excessive space.

For solving the problems of the technologies described above, the utility model is achieved in that

A kind of Folding bench comprises a seat board; Two are locked in the pin joint seat of this seat board bottom, side frames, and wherein arbitrary this bogie side frame has first foot rest and second foot rest, it is characterized in that: but this first foot rest and second foot rest are articulated on this pin joint seat in the folding mode; One expansion link device, be arranged on this bogie side frame, have a flexible mobile jib, its two end is affixed two tranverse connecting rods respectively, be respectively first tranverse connecting rod and second tranverse connecting rod, two ends of this first tranverse connecting rod and second tranverse connecting rod are fixed in respectively on first foot rest and second foot rest of this side frames.

Should have an outer tube by flexible mobile jib; One is inserted in the outer tube and the interior pipe that can be free to slide in outer tube; Two stopper sections are arranged at the front end and the rear end of pipe in this respectively, and outer tube is provided with the hole that blocks the stopper section.

The size and the stopper section of this hole are complementary, and the stopper section just can be exposed to outside the hole.

This stopper section is articulated on the elastic parts that is arranged in pipe.

This elastic parts is spring or shell fragment.

Make by said structure and the utlity model has following technique effect:

The utility model side frames is utilized pin joint seat, but makes seat cushion that the bogie side frame folding draws close Folding bench partly, and the expansion link device can fold the characteristic to the fixed position, makes Folding bench have foldable effect, no matter in collection or carrying does not all take up space; And utilize the expansion link device to may spread to the characteristic of fixed position equally, but when the folding Folding bench is launched, have the fixedly effect of bogie side frame, make it be difficult for producing and rock.

Fig. 6,7, the 8th, user mode schematic diagram of the present utility model.

The specific embodiment:

See also Fig. 1,2, as shown in the figure: Folding bench of the present utility model includes: a seat board 1, take for the user; The isostructural

pin joint seat

6,6 ' of two-phase locks in the bottom of seat board 1 respectively admittedly, is used to articulate the isostructural bogie side frame 2,2 ' of two-phase, and wherein bogie side frame 2,2 ' all has first foot rest 21 and second foot rest 21 '.

See also Fig. 2,3, Folding bench is amounted to the end of fixed structure and is looked expansion and amount to schematic diagram.As shown in the figure: the utlity model has an expansion link device 8 that can fold and stretch, comprise a flexible mobile jib 81 and mid point be fixedly arranged on first tranverse connecting rod 82, second tranverse connecting rod 82 ' at flexible mobile jib 81 two ends, wherein flexible mobile jib 81 comprise in the outer tube 811, a pipe 813 with can slip into, the mode of skidding off is hubbed in the outer tube 811; Offer a hole 812 at outer tube 811 near the front end place, pipe 813 appropriate positions are provided with two stopper sections 814,815 in this, be respectively first stopper section 814 and second stopper section 815, and two stopper sections, 814,815 sizes cooperate above-mentioned hole 812 bores, make it to expose two stopper sections 814,815 to make the fixing usefulness of backstop; When expansion link device 8 folded, first stopper section 814 can engage hole 812, and expansion link device 8 is when stretching, and 815 engagings in second stopper section hole 812 is so that expansion link device 8 can be kept a fixed position when stretching and folding;

First tranverse connecting rod, 82 2 ends of expansion link device 8 with rotary way be articulated in first foot rest 21 of bogie side frame 2 and second foot rest 21 ', second tranverse connecting rod, 82 ' two ends are articulated in bogie side frame 2 with rotary way, first foot rest 21 and second foot rest 21 ', in order to connect side frames 2,2 ' and flexible mobile jib 81.

See also 4,5, they are action schematic diagrames of stopper section in the utility model.Now be example with second stopper section 815, second stopper section 815 has an elastic parts 816 (being a shell fragment or spring), make second stopper section 815 when being subjected to a downforce, can provide the pre-power that makes progress by this elastic parts 816 (being a shell fragment or spring), when pressure was removed, its position can be replied in second stopper section 815; Impose a downforce in second stopper section 815, submerged within the outer tube 811 in the top of second stopper section 815, interior pipe 813 is slipped in outer tube 811, will the postpone inwall of outer tube 811 of second stopper section 815 advances, use folding in pipe 813 in outer tube 811.

See also 6,7,8, they are user mode schematic diagrames of the present utility model.As shown in the figure: second stopper section 815 that at first will snap into hole 812 presses down, submerged within the outer tube 811 in the top of second stopper section 815, and impose an external force interior pipe 813 is slipped in outer tube 811, use and shorten expansion link device 8 length, this action is connected to drive first tranverse connecting rod 82 of expansion link device 8, second tranverse connecting rod 82 ' respectively with bogie side frame 2, a counter-rotation is done in 2 ' articulated section, and make bogie side frame 2,2 ' draws close gradually to seat board 1 direction, when interior pipe 813 slides to the bottom of outer tube 811, then first stopper section 814 is also submerged in the outer tube 811 and the inwalls of the outer tube 811 of postponing advance, and the elastic parts 816 in this moment first stopper section 814 will have the pre-power that makes progress, wherein elastic parts 816 is a shell fragment or spring, when first stopper section 814 advances to the hole 812 of outer tube 811, by the above-mentioned pre-power that makes progress, first stopper section 814 upwards is pushed out of outside the hole 812, and be sticked in the hole 812, pipe 813 can't further slip in the outer tube 811 again in making, use fixing interior pipe 813 position in outer tube 811, at this moment bogie side frame 2,2 ' has drawn close subsides finishes the Folding bench folding to seat board 1 together.
