Abstract

The utility model discloses a hinge with a special structure, in particular to a double rollaway nest hinge, comprising a stationary hinge piece, a movable hinge piece and two pivot shafts which are spaced at a certain distance. The pivot shaft is fixed on the movable hinge piece, and the stationary hinge piece is provided with two curve rollway nests. The pivot shaft is inlaid in the rollway nests and can freely slide, and the stationary hinge piece and the movable hinge piece are connected to form an integral body. The hinge with a special structure has simple and skillful structure, and is appropriate for the doors of furniture, file cabinets, safes and refrigerators and the doors and the windows of buildings to use. When doors and the windows which are provided with the double rollaway nest hinge are opened, the doors and the windows are rotated, the inner walls and the side edges of the doors and the windows are contacted with the different frames of the doors and the windows, and the opening angle can be greater than 90 DEG.

Description

Double rollaway nest hinge

The utility model relates to a kind of hinge of special construction, is specially adapted to sectional furniture.

Existing hinge has blind hinge and a straight door hinge several forms such as (claiming the heart hinge again) of hinge-type hinge, the design of utilization quadric chain principle.With the utility model slightly similarity be a straight door hinge, it is made up of two hinge plates and a pivot, pivot is fixed therein on a slice hinge plate, inserts in the axis hole of another sheet hinge plate, two hinge plates rotate mutually.The advantage of this hinge is that simple in structure, parts can be done lessly, be contained in the upper and lower sides groove of door, close and can not see hinge behind the door, its weak point is that this hinge is a single axle rotation, when opening and closing, door needs bigger space, And and easily can hinder and open the door with the side of doorframe and the inwall severe patient of colliding.

The purpose of this utility model provides a kind of up and down both sides of furniture door that are contained in, and closes and can not see any part of hinge behind the door, and door can not only rotate but also move simultaneously during keying, and open angle can surpass the 90 ° of two raceway hinges that still can not collide with doorframe side and inwall.

The purpose of this utility model reaches with following structure: this pair raceway hinge is formed by deciding hinge plate, moving hinge plate and pivot.The pivot of two (center to center distance) separated by a distance fixedly is housed on one end face of moving hinge plate, decide to have on the hinge plate two shaped form raceway grooves, distance between this two curves raceway groove center line adapts with two pivot center distance, two pivots embed respectively in two curve raceway grooves, can in the raceway groove, be free to slide deciding fuse ， And and pivot of hinge plate and moving hinge plate.The external diameter of the pivot that slides in the raceway groove matches with the width of raceway groove, adopts the matched in clearance structure.When the hinge of this form of structure is contained on the furniture door, moving hinge plate is screwed on the upper and lower two sides of door, decides hinge plate and be fixed on the doorframe.During open and close door, slide in the shaped form raceway groove of two pivots on deciding hinge plate on the moving hinge plate.Because the curve shape of two raceway grooves is according to the open and shut characteristic particular design of door, door is existing function of rotating around doorframe when opening and closing, the function that moves relative to doorframe is arranged again, door side and inwall in opening process are not collided with doorframe (not interfering), and opening angle can be greater than 90 °.

For the frictional force ， And that reduces between pivot and the raceway groove makes the furniture door keying steadily, easily, on two pivots, can respectively overlap a roller, roller outer diameter matches with the raceway well width, is the matched in clearance structure.

Sash structure according to different furniture, this pair raceway hinge decide the structure that hinge plate or moving hinge plate can be designed to have flanging, make two kinds of hinge plates have flanging simultaneously, also can one hinge plate band flanging, another is not with, or other and door and the corresponding type of attachment structure of doorframe.Flanging and hinge plate can be made into integration, but also are assembled after the split manufacturing.

The fixed form of two pivots and moving hinge plate, available threaded connection, riveted joint or weld bonding, interference fit consolidation method.

The utility model has the advantages that: this hinge is the upper and lower both sides that are contained in door, close behind the door hinge by " passs " in the crack between a door and its frame of the upper and lower both sides of door, the hinge any part is not revealed in the outside, an outward appearance harmony that therefore can make.Because pivot slides along shaped form raceway groove, make when opening and closing not only to rotate but also move, so an opening angle that had not only strengthened but also can not collide with inwall, the side of doorframe or other furniture that is close to, this just is specially adapted to combination furniture.In addition, owing on pivot, can be with roller, make that rotation flexibly, steadily when door opened and closed.So few and the Xiao ， And of member of the present utility model and mainly adopt punching press and method for turning is simple in structure, easy to make.This pair of raceway hinge is suitable for door, the window use of the door and the building of general furniture, combination furniture, file cabinet, strongbox, refrigerator.

Description of drawings:

Fig. 1 is a schematic perspective view of the present utility model, and wherein: 1-decides hinge plate, the 2-pivot, and 3-moves hinge plate, and 4 and 5-shaped form raceway groove.

Fig. 2 is the partial cutaway diagrammatic sketch of pivot structure.Be with roller 6 on the pivot 2, pivot 2 links with moving hinge plate 3 usefulness welding manners.

Fig. 3 is the partial cutaway diagrammatic sketch of another kind of pivot structure.The pivot 2 that is with roller 6 directly is fixed on the moving hinge plate with threaded connection.

Fig. 4 is fixed on the moving hinge plate for pivot 2 usefulness nuts link.

Fig. 5 is the partial cutaway diagrammatic sketch of another pivot structure.The pivot 2 usefulness rivetings that are with roller 6 are fixed on the moving hinge plate.

Fig. 6 is with between the axis hole of the pivot 2 of roller 6 and moving hinge plate 3 with being adhesively fixed.

Fig. 7 be the pivot 2 that is with roller 6 with the axis hole of moving hinge plate 3 between connect with interference fit.

Fig. 8 is the sight that two

hinge plates

1,3 have flanging 7 and 8 simultaneously.

Embodiment of the present utility model as shown in drawings.

Embodiment such as Fig. 1, shown in Figure 2.This is to be with roller 6 on a kind of pivot 2, pivot 2 and moving hinge plate 3 usefulness welding manners binding (see figure 2), be contained in the two raceway hinges on the wooden combination furniture door.Known by Fig. 1, on the end face of moving hinge plate 3 two pivots 2 are housed fixedly, decide to have on the hinge plate 1 two shaped

form raceway grooves

4 and 5 that one is long and the other is short, the curve shape of this raceway groove designs according to the keying characteristics of door.Two pivots 2 on the moving hinge plate 3 embed respectively in two raceway grooves.After such hinge was contained on door and the doorframe, pivot moved along the raceway groove when door opened and closed, and made door not only rotate but also move with respect to doorframe, and the maximum opening angle of door can reach 105 °.If the raceway groove is done suitably to extend, then Men opening angle can be greater than 105 °.
