Abstract

The utility model relates to an up-and-over door hinge. A hinge is fabricated to a double rocking lever mechanism by utilizing a four-lever mechanism, a door seat used as a connecting rod and a door frame seat used as a machine frame are hinged with double rocking levers, and the door seat and the door frame seat are respectively connected with a door and a door frame. The function of limit of the utility model is realized by utilizing a characteristic that the double rocking levers are contradicted to each other when the door seat is in an opening position or a closing position; besides, a root of tension spring is connected between the door seat and the door frame to fix the opening position and the closing position of the door seat, and the automatic positioning of a hinge is realized. The utility model can be used as the hinge component of the tip-up door, the tip-down door, and the turnover plate of a cupboard.

Description

Turning over door hange

The utility model relates to a kind of hinge, particularly a kind of Turning over door hange.

At present the cabinet door of furniture mostly be a vertical hinged door, use be the ready-made hinge hinge, or cabinet door 2 supporting hinges up and down, the deadweight of cabinet door focuses on the not work done of keying direction certainly to what the hoisting capacity of cabinet door became 90 ° thereby cabinet door.But for the minority overhead door since the deadweight of cabinet door to opening and closing work done, therefore when using above-mentioned two kinds of hinges, need establish the align member such as three corner bracings in addition, the deadweight that makes overhead door be overcome the cabinet door in the enable possition by manual operations is defined, when closing the cabinet door again armrest go to free three corner bracing positioning supports, make the structure and the operation relative complex of overhead door, influenced the generally use of overhead door style.

The purpose of this utility model is to provide a kind of Turning over door hange, can be advantageously used in tilt-up door or fold-down door, and can be automatically to opening and closing the overhead door location of position.

Task of the present utility model is finished like this: the utilization four-bar mechanism principle, Turning over door hange is made a double rocker mechanism, and promptly two of double rocking lever end points are hinged respectively with as the gate seat of connecting rod with as the doorframe seat of frame.Gate seat has the right angle face that two planes are formed, and one of them plane is hinged of double rocking lever one end, and another plane is the joint face of door, has connecting hole.The doorframe seat has two parallel planes, and fixedly connected by intermediate supports between two planes, one of them parallel surface is hinged of double rocking lever, and another plane is the joint face of doorframe, has connecting hole.The positioner of overhead door is that gate seat is in when opening and closing the position, the competing characteristic of utilization double rocking lever realizes the spacing of this position, and between gate seat and doorframe seat, connect a tension spring, overcome overhead door in the countertorque of the gravity that opens and closes the position by elastic force, make overhead door open and close the location, position opening and closing.

The power of the Turning over door hange that the utility model provides is from the manual force to the cabinet door, because the gate seat as connecting rod is done the motion of level to vertical two positions with the motion of double rocking lever, therefore, the cabinet door of fixedlying connected with gate seat is also done to open and closed action thereupon, and positioner is located on the Turning over door hange, can be spacing in the keying position, simultaneously, overcome the countertorque that the cabinet door is conducted oneself with dignity by spring, make the cabinet door open and close the two positions location.Each cabinet door is established two Turning over door hange and can be installed on demand, realize the cabinet door on turn over or turn over down, easy to operate, the location is reliable, as if being used in combination with vertical hinged door under the situation of a plurality of cabinet doors of combination sideboard, can increase the novelty and the practicality of combination sideboard global design.Utilization is on the fold-down door structure, and this Turning over door hange also can be used for fold-down door double as desk, and the hinged component of shelf is used for the hinged component on convertible bed, the stool.

Below in conjunction with the accompanying drawings concrete structure of the present utility model is further described again with embodiment:

Fig. 1 is connected the structure chart that is in closure state for the Turning over door hange that the utility model provides with the cabinet door.

Fig. 2 is the left view of Fig. 1 structure.

Fig. 3 is the structure chart of Fig. 2 structure cabinet door opening.

Fig. 4 is used for the user mode figure of cabinet door for Turning over door hange.

As shown in Figure 1 and Figure 2, with the sheet material of a right angle face as gate seat 1, it also is the connecting rod of Turning over door hange four-bar mechanism, and a plane of right angle face is provided with the hole that is connected with cabinet door 7 for screw, and two hinge holes that flexibly connect with double rocking

lever

3,4 one ends are arranged on another vertical with it plane.The doorframe seat has two parallel planes spaced apart from each other, 2,5 is middle fixedly connected with support bar, frame as the Turning over door hange four-bar mechanism, one of them plane 2 is provided with the hinge hole that flexibly connects with double rocking

lever

3,4 other ends, the length on another plane 5 is greater than plane 2, and the two ends that its length exceeds plane 2 are provided with the hole that is connected with doorframe for screw.Located being opened into horizontal level or being closed to the upright position in order to make the cabinet door, in design as shown in Figure 3, double rocking lever is in the mutual alignment of gate seat hinged place during according to unlatching and closure, by bending and width, the adjustment of top length, top and another root rocking bar of a rocking bar in the double rocking lever are opened above-mentioned, it is inconsistent to close the position, with as spacing, and a tension spring 6 is set between double rocking lever, the two ends of spring 6 are connected with the doorframe seat with gate seat respectively, cabinet door 7 is fastened by elastic force when make position, particularly when the enable possition, elastic force is enough to overcome the opposing torque of cabinet door 7 deadweights to Turning over door hange, make it to be fixed on the horizontally openable position, the joint hinge that tension spring 6 is installed will be set on gate seat and doorframe seat for this reason, and present embodiment is as joint hinge with pin on the gate seat and a support bar on the doorframe seat.Fig. 4 is use location and the state diagram of Turning over door hange in the cabinet door 7 of cupboard 8.As this Turning over door hange being used for the hinge that Fig. 3 makes then to can be used as when use Rotate 180 ° position fold-down door, movable support, shelf, bed, stool.Use and adjust the inconsistent position of double rocking lever as this Turning over door hange Fig. 3 being done 90 ° of positions of dextrorotation, make gate seat and doorframe seat when the open limit angle is the obtuse angle, can make the hinge of case lid again, can omit at this user mode lower pulling force spring, because can locate by the deadweight of case lid hypsokinesis.
