Abstract

The utility model relates to a cross door opening mechanism, belongs to a novel pivot mechanism which is provided with a link mechanism. The link mechanism comprises four pivots which are arranged on upper and lower angles of both sides of a door, four pivot seats which correspond to the four pivots, and four roots of links which are arranged at the upper and the lower ends of the door, wherein, two pivots which are passed through a U-shaped plate are connected with the door and a window. The mechanism can be used on a refrigerator, or a cupboard, and can also be used on a plurality of door leaves of especial houses.

Description

Cross opening door mechanism

The utility model is the novel door-hinge mechanism that is used on the various door such as refrigerator, cabinet, housing window.

Door on present various refrigerator, cabinet and the housing window all is that a side of door leaf is passed through door-hinge mechanism, is installed on the doorframe, so door leaf all can only be opened promptly unidirectional opening the door to a side; If change the opening direction of door, just must repacking door-hinge mechanism, change its position, the left and right sides, " long Cen--Ali Si " board refrigerator for example is by changing the position of door-hinge mechanism, realize the change door of refrigerator open to.Other can make in this way too as cabinet, housing window etc., change the opening direction of door leaf.No matter but any door once repacking, has just all lost the direction of opening the door originally again, so its still fixing unidirectional opening the door.

The utility model is the novel door-hinge design of doing at above-mentioned situation.Use the door of this type gate axis mechanism,, can or adjust formality, just can arbitrarily open the door to the left or to the right, realize bi-directional door without any repacking owing between door leaf and doorframe, used linkage.

Below in conjunction with accompanying drawing structure of the present utility model and effect are described.

Shown in Figure 1 is the front view of a left and right opening door; Fig. 2 is the upper and lower left and right pseudosection of door.

Door leaf 1 is identical with common door leaf, but respectively there is a door-hinge at the upper and lower angle of its both sides, i.e. 2a, 2b, 2c, 2d; Doorframe 3 with the corresponding position of each door-hinge on, a door-hinge seat is respectively arranged, i.e. 4a, 4b, 4c, 4d; Upper and lower side at door is equipped with four connecting rod A, B, C, D in addition. A is connected between 4a and the 2b; B is connected between 2a and the 4b; In the bottom, C is connected between 4c and the 2d equally; D is connected between 2c and the 4d. Therefore door leaf just has the function of arbitrarily opening to the left or to the right. Because 2b is in the top of 4b, and 2c is in the below of 4C, so door-hinge 2b and 2C must respectively through a U-shaped metal plate, be connected on the door leaf 1.

When left and right opening door is used as housing window, need to be equipped with two door handles that reciprocal interlock 5, its effect one is the locking door and window; The 2nd, when pulling a door handle, another is just locked, can not pull the possibility of avoiding two people to open the door to both direction simultaneously. On refrigerator or cabinet when using this door, because on the door magnetic stripe or collision bead are arranged, so do not use this door handle that reciprocal interlocks.

Left and right opening door mechanism compares with existing common door axis mechanism, has the advantage of using maneuverability, can provide convenience for the end user.For example, just can open the door, and the people who comes from the left side can open the door from the left side from the right side from the right side messenger.

Left and right opening door is used on the refrigerator or on the cabinet, can improves its adaptive capacity at indoor placement location; During as the room door, can be the track route that the pedestrian provides most convenient; During as sash or external door its difference open to, can also create best natural ventilation condition.These all be to use the common door axis mechanism can't realize.

Four connecting rods only Duo than general door-hinge mechanism in the door-hinge mechanism of left and right opening door, and this connecting rod can be made with the thin iron metal plate of 2 millimeters thick, and processing and installation are all very simple.But various door leafs not of uniform size so can't stipulate the common-use size of connecting rod.So this type gate axis mechanism part preferably as the attached product of door, is produced with door leaf simultaneously.

Claims

1, a kind of left and right opening door mechanism comprises four door-hinge 2a, 2b, 2c, 2d on the door leaf 1, four door-hinge seat 4a on the doorframe 3,4b, 4c, 4d, connecting rod A, B, C, D, door handle 5; It is characterized in that: between door-hinge (2a, 2b, 2c, 2d) and door-hinge seat (4a, 4b, 4c, 4d), one group of connecting rod (A, B, C, D) has been installed.

2, left and right opening door as claimed in claim 1 mechanism is characterized in that connecting rod A, C the door-hinge 2b and the 2d on right side on the door leaf 1, is connected on the door-hinge seat 4a and 4c in doorframe 3 left sides; And connecting rod B, D the door-hinge 2a and the 2c of door leaf 1 upper left side, are connected on the door-hinge seat 4b and 4d on doorframe 3 right sides.

3, left and right opening door as claimed in claim 1 mechanism is characterized in that: door-hinge 2b and 2c are connected on the door leaf 1 each through a U type metal plate.
