Abstract
The utility model relates to a support piece of a movable backrest of an upholstered armchair; the support piece is composed of two rod pieces, clamping sheets and springs. Coupled support can be used for the movable backrest of the upholstered armchair and a support piece of a retractable table top.
Description
The invention belongs to the support member of the active face of furnitures such as sofa chair.
The supporting way of the movable back of existing known sofa chair, cantilever was bigger when perhaps backrest fell, perhaps complicated trouble of using of structure.
Task of the present invention is can improve force-bearing situation for the movable back design of sofa chair is a kind of, uses more convenient and the better simply support member of structure.
The technical scheme that interlock supports is: it is by upper and lower two rod members that interlock supports, and a card and a spring are formed.Card is installed on the upper lever by pin and links to each other with spring.The following rod member that has the latch part, its upper end is connected on the upper lever, and tie point is between the two ends of upper lever.When upper lever and following rod member rotate around tie point, when the ratchet clamping part phase-splitting on card on the upper lever and the following rod member on the correspondence position is close to a certain degree mutually, the card ratchet embeds the latch part automatically and latch partly meshes, and makes upper and lower bar in conjunction with separating along opposite direction automatically; Make card ratchet and latch partly break away from when engagement when moving card, upper and lower rod member can separate around the tie point backward rotation.
The advantage that interlock supports is: its varied angle that can not only realize movable back supports more conveniently, and because backrest landed the support backrest in the lower end of upper lever when falling automatically, has therefore reduced the cantilever of backrest compared with the structure that only depends on sofa frame to support backrest; The structure that supported backrest again compared with falling earlier is more easy to use.Interlock supports and to be specially adapted to the higher and situation when needing backrest and seat board to have than mitre of backrest, can provide a kind of structure the simpler lighter chair of using for industries such as beauty treatment, haircut, dentistry.
Accompanying drawing 1 is interlock supporting construction figure.
Accompanying drawing 2(a), be that interlock supports the use schematic diagram accompanying drawing 2(b).
As Fig. 1: interlock supports by upper lever (1), rod member (2), card (3) and spring (4) are formed down.Card (3) is installed in upper lever (1) by pin F and upward also links to each other with spring (4).The following rod member (2) that has the latch part A, its B end is connected on the upper lever (1), and tie point B point is positioned at the DC section of upper lever (1).When upper lever (1) and following rod member (2) rotate around the B point along the direction that ∠ ABC reduces, when the latch part A on the last correspondence position of card (3) on the upper lever (1) and following rod member (2) is close to a certain degree mutually, the ratchet of card (3) embeds the latch part A automatically and meshes, define the increase of ∠ ABC, the direction that upper lever (1) and following rod member (2) can't increase along ∠ ABC is automatically rotated.When the ratchet of card (3) and latch part A broke away from engagement, upper lever (1) and play rod member (2) can be around the direction rotation of B point along ∠ ABC increase.
As Fig. 1 and Fig. 2 (a), the D of upper lever (1) end is contained on the sofa backrest by bearing (5), and the E end of following rod member (2) is contained on the member of sofa frame by bearing (6).When backrest is holded up, the angle of backrest and seat board reduces, the angle ∠ ABC of upper lever (1) and following rod member (2) also reduces, automatically embed the latch part A and mesh until the ratchet of card (3), the direction rotation that upper lever (1) and following rod member (2) combine and can't increase along ∠ ABC automatically, thus realization is to the support of backrest.
As Fig. 1 and Fig. 2 (b), when ratchet that makes card (3) by position hand (7) and steel wire (8) and latch part A disengaging engagement, upper lever (1) and following rod member (2) can rotate along the direction that ∠ ABC increases, thereby backrest and seat board can rotate until the C of upper lever (1) end to the direction that angle increases and land, and realize the support to backrest.
As Fig. 1, card (3) also can be made the form that has 2 or 2 above ratchets, thereby ∠ ABC has a plurality of qualifications position to realize the multi-angle support of backrest.
Claims (3)
1, interlock supports, and it is characterized in that it is by upper lever (1), rod member (2), card (3) and spring (4) are formed down.Card (3) is installed in upper lever (1) by pin F and upward also links to each other with spring (4).The following rod member (2) that has the latch part A, its B end is connected on the upper lever (1), and tie point B point is positioned at the DC section of upper lever (1).When upper lever (1) and following rod member (2) rotate around the B point along the direction that ∠ ABC reduces, when the latch part A on the last correspondence position of card (3) on the upper lever (1) and following rod member (2) is close to a certain degree mutually, the ratchet of card (3) embeds the latch part A automatically and meshes, define the increase of ∠ ABC, the direction that upper lever (1) and following part (2) can't increase along ∠ ABC is automatically rotated.When the ratchet of card (3) and latch part A broke away from engagement, upper lever (1) and play rod member (2) can be around the direction rotation of B point along ∠ ABC increase.
2, interlock supports according to claim 1, it is characterized in that the D end of upper lever (1) is contained on the sofa backrest by bearing (5), and the E end of following rod member (2) is contained on the member of sofa frame by bearing (6).
3, interlock supports according to claim 1, it is characterized in that card (3) also can make the form that has 2 or 2 each and every one above ratchets.
