Abstract
The utility model discloses an outdoor automatic guard couch, mainly relates to a clean and dry couch for people in a public place and overcomes the defects that people are unwilling or cannot sit because the traditional couch in the public place has no functions of preventing dust, screening sun and shielding rain. The outdoor automatic guard couch is characterized by consisting of a backrest, hinges, a seat board, couch legs, a supporting device and a speed-controlling spring, wherein the supporting device is fixed below the seat board and can achieve the function of enabling the backrest to not fall off when the couch is in use. A folding lever comprises a straight end and a folding end; and a cylindrical rod is close to the front edge of the seat board and is slightly higher than the seat board. The speed-controlling spring is arranged between the lower part of the backrest and the seat board, can drive the backrest to fall down when not in use, can control the speed of the backrest to fall down to a certain degree and reduce the vibration in an instant when the backrest is contacted with the seat board. The utility model has the advantages of simple design, low cost and easiness of generalization.
Description
Affiliated technical field
The utility model relates to a kind of Public chair, particularly can prevent dust, rainproof, sun-proof outdoor automatic protection chair.
Background technology
Supply the chair of visitor's rest at present on park and the shopping mall, dust is more generally speaking, seat board is hot easily when the sun is big, owing to the device that does not have to prevent dust, prevent rainwater, much all messy or residual have rainwater and cause people to be reluctant maybe can not use, particularly after raining, seat drenches just and can not use.Wherein the patent No. is 200810008121.5, the utility model of by name " chair " with the member of closing backrest automatically specifically be configured to the seat, it is designed to around the support bar rotation that is fixed on the seat mount, and reception and support bar are separated by to the elastic force of the elastic component generation of set a distance; Backrest, it is designed to respect to the seat rotation, and has a supporting projections that is formed near the end in seat; Supporting member, it is installed in seat back, and according to the rotation situation of backrest with the supporting projections contact or separate; Hinge-unit, the backrest that it connects the seat and will rotate, and have first hinge member and two second hinge members that are connected to backrest that are connected to the seat; Buffer cell, it provides first and second hinge members to do the cushion effect of counterrotating given range; And the pressure member that inserts seat and backrest respectively, this member is made by having the material higher than the hardness of seat and backrest.But this structure is comparatively complicated, is unfavorable for promoting.
Summary of the invention
The purpose of this utility model is easily dirty at ordinary times in order to overcome existing Public chair, and easily drenched rainy day, fine easily scalding and defective that can not be for people to use, thus a kind of dustproof, rainproof, sun-proof outdoor automatic protection chair is provided.
The technical solution of the utility model is: be made up of backrest, hinge, cylindrical rod, control speed spring, seat board, bracing or strutting arrangement, chair legs, arm spring, supporting projections, pole and folding shape lever, backrest is connected by hinge with seat board, bracing or strutting arrangement is fixed on the below of seat board, controls fast spring and is connected on backrest and the seat board.The connecting portion of hinge is backrest the place ahead and seat board top.Bracing or strutting arrangement comprises cylindrical rod, and cylindrical rod and seat board are isometric, and leans against the leading edge of seat board, and is higher slightly than seat board; Folding shape lever, the two ends of three identical folding shape levers are divided into straight end and folding end, and the folding end bends out sub-fraction and is formed with supporting projections, and straight end all is fixed on two ends and the middle part on the cylindrical rod; Pole is installed between folding shape lever and the seat board, and the pole plate leading edge that disseats is nearer, and the pole other end is connected with folding shape lever, the material of three poles with roll over the identical of shape lever; Arm spring is parallel with pole, is connected on folding shape lever and the seat board, and is far away apart from cylindrical rod.Two fast springs of control are fixed between three folding shape levers, and its two ends are installed in the lower part of backrest and the below of seat board respectively, when backrest and seat board angle are 80 when spending, control fast spring and are in natural length.
The beneficial effects of the utility model: simple in structure owing to the design uses hinge instead to connect backrest and seat board on the basis of original chair, can not cause the inconvenience in the making, cost is low, is easy to produce.Because the design installs a bracing or strutting arrangement below seat board, do not allow backrest fall down in the time of can realizing using chair.Because the design is equipped with the fast spring of control between the lower part of backrest and seat board, can when not needing to use chair, drives backrest and fall down, and, reduce the vibration that backrest caused in the moment that contacts seat board in the speed that the back control backrest to a certain degree of falling down falls down.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
(each mark is consistent with each identical point mark of Fig. 2 among Fig. 1)
Fig. 1 is an overall structure schematic diagram of the present utility model
Structural representation when Fig. 2 is the utility model inversion
Among the figure: 1. backrest, 2. hinge, 3. cylindrical rod, the 4. fast spring of control, 5. seat board, 6. bracing or strutting arrangement, 7. chair legs, 8. arm spring, 9. supporting projections, 10. pole, 11. folding shape levers.
The specific embodiment
As Fig. 1-shown in Figure 2, the utility model is when unmanned the use, and backrest 1 falls down, and controls fast spring 4 and is in extended state, and arm spring 8 is in natural length; During use backrest 1 is propped up, this time control speed spring 4 is compressed, and the people takes the back thigh cylindrical rod 3 is pressed down, because leverage, supporting projections 9 moves upward, and props up backrest 1 lower part, make backrest 1 be fixed on the position of opening of this moment, this moment, arm spring 8 was compressed.After the people left, arm spring 8 will recover deformation, and the folding shape end of folding shape lever 11 is moved downward, because leverage, cylindrical rod 3 will be got back to original position, and supporting projections 9 breaks away from backrest 1 simultaneously; There is not the support of supporting projections 9, control fast spring 4 and recover deformation, promote backrest 1 and fall down, when backrest 1 move to seat board 5 angles be 80 when spending, control fast spring 4 and be in natural length, because effect of inertia, backrest 1 can continue to draw close to seat board 5, and this crosses program control fast spring 4 and is stretched, under the elastic force effect, the speed of backrest 1 motion is reduced, so just reduced backrest 1 and contacted the vibration that moment produces with seat board 5.
