Abstract
The utility model is improved aiming at the disadvantages of cushion easy rearward turn of a seat pad, insufficient bearing capacity of the plastic seat pad, dot or linear contacting support of a front and a back brackets of the chair when contacting the ground, etc. Of an ordinary folding chair. The utility model is characterized in that the front bracket and the back bracket of the folding chair of the utility model are combined in a sliding sleeve mode; the middle part and the back part on both sides of the seat pad are respectively pivoted on the front bracket and the back bracket to obtain that the seat pad has no danger of turning rearward. In addition, matched with the design of the backrest pad, the seat pad and the non-slipping blocks in the front bracket and the back bracket, a folding chair structure with safe and comfortable sitting, firmness and durability is generated.
Description
The utility model relates to the structure of fold-down seat, refers to especially a kind ofly take advantage of a safety and comfort, and firm and durable, its seat cushion fold-down seat that front and back support amounted to starting the back.
The fold-down seat that general seat cushion amounts to front and back support starting the back, because of it has the advantage that folding does not take up space, so the approval that extensively is subjected to the consumption market with like, and because consumer's constantly being particular about the PRODUCT FORM DESIGN art atmosphere, so the creation of fold-down seat mostly trends towards the aesthetic feeling and the comfortableness of moulding, outward appearance, but then there is no concrete and effectively improve for the existing shortcoming of fold-down seat for a long time, this as:
(1) seat cushion of general fold-down seat, because seat cushion is articulated in fore-stock with the stage casing, both sides, and seat cushion both sides rear end side is preset in the after-poppet book office from bottom to top, so seat cushion can produce the situation that has a down dip backward when the stressed inclined to one side back segment of seat cushion, and this situation is common in child and takes or stand on seat cushion when the back segment, the lighter is subjected to frightened conspicuous, and weight person is injured.
(2) present fold-down seat is by the iron seat cushion of tradition, evolve to different materials such as wooden, plastic cement, and more common plastic cement seat cushion is because burn into is not rotten, so adopted, but engaging between plastic cement system seat cushion and chair frame, because stressed bigger cause, so all add iron plate to make up for the pivot joint of chair frame in the articulated section of plastic cement seat cushion, and this kind reinforcement only reaches in desire and articulates part, there is no for the bearing strength of seat cushion itself and benefit, and the formula iron plate of adding also destroys the global design aesthetic feeling.
(3) the general fold-down seat front and back support part that is used for landing all contains with C shape cover piece and places bracket bottom cross bar lower edge, or bring in ground under the cross bar of support with the chock choker block and to contact, and this kind only contacts the contact for point or line with ground, be not that mode with face lands, so stent support lands effect a little less than, stationarity is also relatively poor.
Therefore, the purpose of this utility model just is, makes that general fold-down seat seat cushion is easily tumbled, the stressed deficiency of plastic cement seat cushion, land non-shortcomings such as support of support, and mat structure creation of the present utility model is improved fully, is prevented.
The purpose of this utility model is achieved in that the structure that a kind of fold-down seat is provided, it includes a fore-stock, an after-poppet, and an assembly is in the back cushion of fore-stock top, the seat cushion of one assembly between front and back support, and the non-slipping block that lands that lands bottom the front and back support.Binding combination system between fore-stock and after-poppet utilizes the quill of upper end, after-poppet both sides to come the tandem arrangement slippage on the body of rod of the both sides of fore-stock, this quill system location is articulated in each side top of after-poppet, and have a hollow channel for the fore-stock tandem arrangement on quill, the quill location tandem arrangement slippage that makes this after-poppet is between back cushion lower edge and seat cushion pin joint seat on each side lever body of fore-stock.Assembly is in the back cushion upper limb of fore-stock upper end, is provided with an arc neck that inclines and stretch to the back upper place with set angle, and the back cushion lower edge is then tiltedly stretched a curve bottom with a set angle to the back lower place.The bottom cross bar lower edge system of front and back support is respectively equipped with a predetermined locating hole, with predetermined non-slipping block that lands of assembly.Assembly is mouthful design that contains towards upper shed in the non-slipping block that lands of front and back support bottom cross bar, in it contains mouth, be provided with and fill in the card post that is buckled in front and back support cross bar lower edge locating hole, and the root edge of the non-slipping block that respectively lands is parallel design with containing mouthful inner bottom surface non-to each other.The inside, the left and right sides of seat cushion is embedded with reinforcing chip respectively, and corresponding fore-stock seat cushion articulated section, this reinforcing chip stage casing system is provided with runs through dispensing hole, uses with fore-stock seat cushion articulated section articulating.Reinforcing chip then is provided with a pivot connecting plate that stretches out the seat cushion outside corresponding to the positioning supports point place of after-poppet.The pivot connecting plate that after-poppet positioning supports point then stretches out the seat cushion outside therewith articulates.So, seat cushion just articulates with front and back support by this reinforcing chip.
Folding of the utility model fold-down seat is that upwards pull when lifting the seat cushion front portion, impels the stressed decline of after-poppet by seat cushion rear end pivot connecting plate, i.e. the quill of after-poppet slippage downwards on the fore-stock side lever is so that fold seat cushion.So it folds is to turn on the seat cushion, fore-stock rises, and after-poppet descends relatively and finishes.During expansion, seat cushion is opened to the front lower place, then fore-stock is to decline, and the slippage of then rising of the quill of after-poppet launches up to seat.
On structural design, the utlity model has following safety and firm benefit:
(1) be the particular design of utilizing the after-poppet quill because of the utility model, come tandem arrangement to be connected in the body of rod of fore-stock, to reach front and back support binding combination to each other, so that the strong point that is connected of seat cushion and after-poppet, become a unshift positioning supports point, therefore when the power of taking concentrates on the seat cushion rear, the dangerous facts that seat cushion does not have sagging tipping folder people extremely takes place, so security is conclusive, do not have traditional fold-down seat extremely and sit, stand child when leaning on the rear partially, seat cushion turns over the danger that crushes the people after taking place at once to sink.
(2) the utility model and fore-stock, the pivot joint system between after-poppet bears with the reinforcing chip of burying underground in the seat cushion, so the structural strength excellence, relative holding capacity is strong, takes safe, firm.
When (3) front and back support lands, be that the non-slipping block that lands that lands with face posts ground, so landing ground is firm, holding capacity is big.
(4) incline the arc neck stretched and the design of curve bottom of all oriented back upper place of the last lower edge of back cushion and the back lower place, make the layback of occupant's upper body be posted by the back cushion upper limb, or reach forward the back when putting the back cushion lower edge, and all have comfortablely by putting face, make the use of seat more become perfect, comfortable.
