Abstract

The utility model relates to the improvement for a hinge for a door, a window and furniture, which forms a linking mechanism by a base [6], auxiliary double-rocking rod members [2], [9], a door base [11], four connecting rod members [7], [5] and a spring [3]. When a door leaf is opened or closed, the upper connecting rods [7] drive the auxiliary double-rocking rods to swing, and the lower connecting rods [5] make the door depart from or close to the bottom line of a doorframe base; the spring [3] keeps the door at a relatively stable position when the door is closed, and the door base and the lower connecting rod [5] keep the door relatively stable when the door is opened. The built-in hinge of the utility model can be fixedly installed without the need of providing a hole or chiselling a concave position on the door or the frame, has enough hanging force, and can be used for various doors and windows or the furniture.

Description

Easy-to-install built-in hinge

The invention belongs to the improvement of door and window and Domestic hinge.

The blind hinge of producing both at home and abroad that is used on door and window and the furniture is various informative, various in style at present.But blind hinge abroad mostly number average adopt the double rocking lever structure, and just risen at home with the blind hinge that this structure is made, reason such as little or installation inconvenience makes its application be subjected to certain limitation owing to its suspension force.A kind of blind hinge of selling as cash sale on the market, its structure and form roughly with " external furniture atlas " in the 148th page of hinge that the upper left corner is drawn basic identical, but slightly have any different, the double rocking lever member that it is made by base, metal material and form with the top locking device that spring withstands a similar hoodle, its unlatching rotational angle is about 90 °.Owing to will on the installation position of doorframe or door leaf, bore the hole, garden when installing or the cutter recess could be installed, so limited the width of rocker member, make its suspension force little, on the doorframe of frame construction, installation is a hang-up to be solved especially.In addition, though it has a top locking device, it can only make door leaf keep relative stability when closing, just inoperative when opening, door is swung back and forth, make it stable, just necessary feeder apparatus in addition, this makes troubles for daily use.

The present invention is on the structure of blind hinge, done improvement, thereby the problems referred to above have been solved, a kind of existing enough suspension force are provided, the easy for installation again and blind hinge of position that makes it all can keep relative stability when being in the opening and closing position, by retrieval still finds no the blind hinge identical with feature of the present invention.

Main points of the present invention are the double rocking lever on original blind hinge is changed into four connecting rods of a fixed point and three moving points, superposeed again on this basis one and paid double rocking lever, make it to form the link gear of four connecting rods and double rocking lever, and add a spring in the above, can not only make the hinge activity freely like this, and make it open or close the Shi Junneng position that keeps relative stability, its maximum characteristics are easy for installation, not be used in boring or cutting recess on doorframe or the door leaf, structure of the present invention as shown in drawings.It is the schematic diagram of an embodiment, and (1), (4), (8), (13) are long pin or claim bearing pin among the figure, and (10), (12) have been the dump bolts that the riveted joint effect also can be rotated.(2), (9) be and pay a rocker member, (2) are that rocking bar is paid in the back, also are the back links of four connecting rods, (9) be preceding pair of rocking bar, the two forms a pair double rocker mechanism.(5) be lower link, (7) are that the connecting rod of pair double rocker mechanism also is the last connecting rod of quadric chain, and (6) are bases, are the fulcrums of paying a double rocking lever (2), (9).Also be the fulcrum of lower link (5), protruding position and fixing hole are arranged on the bed plate, (11) are gate seats, also are the front rods of quadric chain, and it connects upper and lower connecting rod, and protruding position and fixing hole are arranged on the base plate.(3) be mounted in spring on the bearing pin (1).

Particular content of the present invention is: pair double rocking lever (2), (9) are fulcrum with base (6), connect connecting rod (7) simultaneously, one of spring (3) after being installed on the connecting axle (being pin) (1) of pair rocking bar (2) and connecting rod (7) end hasp is lived pin (8), other end hasp is lived pin (4), borrow spring force to make the rotatory force of connecting rod downward all the time, impel gate seat (11) (front rod) member to rely on base.Spring (3) also can be installed on pin (8) or (10), and its effect is identical with the effect on being installed in pin (1).Last connecting rod not only was connected with two moving points of paying double rocking lever but also with gate seat, and lower link links to each other with the connecting axle (4) of back pair rocking bar and base.If base is fixed on the doorframe, gate seat is fixed on the door leaf, when door leaf is closed, because the active force of spring makes hinge be in position shown in the accompanying drawing, forms right angle type between gate seat and the base, but is not limited to the right angle.Its angle also can be determined with paying the rocking bar fulcrum or the position of tie point or the length of bar before adjusting during fabrication according to the concrete condition of doorframe installation position.Therefore, pin (8) also can be considered the spacing point of door angle when closing.

When door was opened, door leaf rotated, i.e. gate seat member rotation, and pay double rocking lever by last connecting rod drive and rotate, simultaneously, lower link is followed upwards rotation, and it is outwards mobile to push away door, makes door leaf leave doorframe seat bottom line.When forwarding certain angle to promptly during the door complete opening, the face that touches of two members of gate seat and lower link offsets, and door can not be opened greatly again, because spring makes connecting rod downward, and gate seat and lower link offset, and mutual force balance remains on the relatively stable position of certain angle door.The opening angle of door can be regulated as change gate seat base plate size with changing the offset way of position of gate seat and lower link.Therefore, pin (15) can be considered the spacing point that door leaf is opened.Blind hinge of the present invention can be made with metal material with certain intensity and hardness or plastics.When mounted, also can as required base be installed on the door leaf, gate seat is installed on the doorframe and uses.

The present invention has advantages such as making easy, rational in infrastructure, firm durable and practicality compared to prior art, if widen the link component size, can increase its suspension force, makes it to be applied on the large and medium-sized door and window, makes its range of application wider.Owing to adopt spring and connecting rod link gear, Men Zaiwei is subjected under the situation of certain external force, can be because of wind-engaging or the other factors function influence door position that when closing or open, keeps relative stability.Particularly compare with existing blind hinge, its maximum characteristics are all to use flat the decision by four connecting rods that adopted and double rocking lever link gear and base and gate seat, make it to install very easy, and need on the installation position of framework or door leaf, not bore circular hole or dig recess, as long as directly can fix with screw or rivet once mounting, or install with welding method, and, can do trace adjustment to setting angle or position as required when mounted.The present invention can be used on all kinds of door, the window or on the door leaf of furniture.
