Abstract

The utility model provides a position limit safety structure of rocking chair, relating to a rocking chair which mainly solves the technical problem of supplying a safe and reliable rocking chair. The corresponding technical proposal is that a limit rod is arranged between two axle rods. The limit rod limits the rocking angle of an axle rod to keep the rocking travel route of the seat. The limit rod is connected with an axle connecting part between the axle rod and the seat. The space between the two axle rods and the seat is not larger than the space between the two axle rods and a support. The utility model is applicable to the rocking chair with the seat and the support connected by the axle rod.

Description

The spacing safety configurations of rocking chair

Technical field:

The utility model relates to the assembly of a kind of rocking chair, particularly a kind of rocking chair.

Background technology:

Raising along with standard of living, for increasing the diversified of seat and the user being provided better comfort, at present, but various seat is all towards the designs of the swivel chair or the rocking chair of relative motion, visible on the market at present rocking chair structure is that the bracing frame in seat 1 ' below constitutes by a seat 1 ' and a winding, and seat 1 ' is to utilize two shaft lever to be connected with bracing frame two sides, mat bracing frame and axostylus axostyle articulated section are fulcrum, but make the corresponding bracing frame of seat 1 ' the mat axostylus axostyle do forward and backward oscillating motion.

But, the user falls seat 1 ' when shaking situation often takes place in said structure, its reason is, when seat 1 ' when nosing force is excessive forward or backward, because the two shaft lever design of its pendulum angle without limits, the oscillating stroke of seat 1 ' does not suffer restraints, when seat 1 ' waves above bracing frame, body weight for humans adds that seat 1 ' weight is quickened after losing the critical degree of support forward or backward gravity and accelerated, thereby cause seat 1 ' to descend earthward suddenly, form as Fig. 1, out-of-balance condition shown in 2, at this moment, be sitting on the seat 1 ' human body therefore emergency case and producing to front or rear fall, often cause grievous bodily harm, simultaneously, when above-mentioned unbalance situation takes place, two shaft lever is out of shape or fracture along with meeting is distorted, and causes heavy damage rocking chair structure.

Summary of the invention:

Technical problem to be solved in the utility model is that a kind of rocking chair that can reliably use that can guarantee personal safety is provided.

The technical scheme that solves the problems of the technologies described above employing is to be connected with a restriction axostylus axostyle pendulum angle to keep the gag lever post of the certain oscillating stroke of seat between two shaft lever.

Gag lever post is the place that is coupling that is connected axostylus axostyle and seat, and the join spacing at seat place of two shaft lever is not more than the join spacing at bracing frame place of two shaft lever.

The setting of the utility model mat gag lever post with better simply structure, makes seat when swing no longer because of the excessive generation capsizing case of oscillatory forces, guarantees personal safety, also damaged member no longer.

The specific embodiment:

With reference to Fig. 3,4,5, rocking chair 1 of the present utility model includes a bracing frame 12 and and is configured in seat 11 on the bracing frame 12, seat 11 is to include a cushion portion 111, one is fixed in seat 11 cushion portions, 111 rear ends and stretches the portion that leans against 112 that back chair pin 113 is arranged, and one be installed in cushion portion 111 and lean against portion's 112 2 sides and extend the handrail 114 of front chair leg 115, preceding, back chair pin 115,113 are connected with a connecting rod 116, bracing frame 12 is to be made of several cross bars 122 that two bendings are connected to the straight-bar 121 on ground and are fixed in 121 of two straight-bars, connecting rod 116 2 sides of bracing frame 12 and seat 11 are to utilize the part 131 that is coupling, 132 wear two shaft lever 13,13 ' connects, make the seat 11 can be with axostylus axostyle 13,13 ' and the place of being coupling of bracing frame 12 for before fulcrum does, back wobbling action, at two shaft lever 13, be to utilize fixture 141 between 13 ' with one, 142 gag lever posts that wear 14 connect, with restriction axostylus axostyle 13, be to utilize fixture 141 between 13 ' with one, 142 gag lever posts that wear 14 connect, with restriction axostylus axostyle 13,13 ' pendulum angle, gag lever post 14 is to be connected contiguous axostylus axostyle 13,13 ' and the place that is coupling of seat 11, and make two shaft lever 13,13 ' the spacing of joining seat 11 places is not more than two shaft lever 13,13 ' the spacing of joining bracing frame 12 places is used and is reached the effect that seat 11 can be kept certain oscillating stroke.

With reference to Fig. 4,5, utilize gag lever post 14 to connect two shaft lever 13,13 ', when seat 11 relative bracing frames 12 are waved, be subject to gag lever post 14 and restrain two shaft lever 13,13 ' pendulum angle, seat 11 also is tied at certain oscillating stroke, and diagram is because seat 11 oscillating strokes are limited, reason power is excessive and exceed bracing frame 12 when making seat 11 swing, thereby can not produce seat 1 ' the tipping accident of traditional rocking chair.

Claims

1. spacing safety configurations of rocking chair, this rocking chair includes a bracing frame and a seat, bracing frame and seat two sides are to connect two shaft lever respectively, seat is that fulcrum is done forward and backward swing with the place of being coupling of axostylus axostyle and bracing frame, it is characterized in that: two shaft lever is connected with restriction axostylus axostyle (13,13 ') pendulum angle to keep the gag lever post (14) of the certain oscillating stroke of seat (11) between (13,13 ').

2. the spacing safety configurations of rocking chair according to claim 1, it is characterized in that gag lever post (14) is the place that is coupling that is connected axostylus axostyle (13,13 ') and seat (11), join spacing that seat (11) locates of two shaft lever (13,13 ') is not more than two shaft lever (13, the 13 ') spacing that bracing frame (12) locates of joining.
