Description

Invisible hinges for casement doors and windows

technical field

The utility model relates to a door and window opening and closing transmission hardware, in particular to an invisible hinge for a casement door and window.

Background technique

Ordinary doors and windows are opened and closed through hardware connectors such as sliding braces and hinges. The most common hinges on the market are a type of sliding rail, slider, top support cantilever, short support cantilever, support cantilever and long support. The sliding support hinge assembled by the cantilever: the short supporting cantilever, the supporting cantilever and the slider are hinged correspondingly and then loaded into the slide rail; Correspondingly hinged to form a kinematic mechanism. One end of the slide rail is provided with a guiding apex, which guides the opening and closing of the hinge. A pair of sliding braces are installed on the casement window, and when the window sash is pushed, the window sash transmits the force to the moving mechanism through the cantilever mounted on the window sash. Since the slider can slide in the slide rail, the kinematic mechanism moves under the force so that the window sash can be opened and closed. For a door or window using this hinge, the opening and closing angle depends on the sliding distance of the slider on the slide rail. Therefore, in order to meet the needs of daily life, the overall size of the hinge must be larger, which greatly increases the window and door. The design is difficult, the versatility is not high, and it is not easy to install and produce.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide an invisible hinge for casement doors and windows that replaces the slide rail and the slider with a chute structure, thereby greatly reducing the volume and improving the convenience of installation and production.

The technical scheme adopted by the present invention is as follows: the present invention comprises a base plate, a long overhang, a short overhang and a support piece, one end of the long overhang is hingedly connected with the lower end of the base plate, and the other end is hingedly connected with the support piece, and the One end of the short overhang is hingedly connected to the middle end of the bottom plate, and the other end is hingedly connected to the support piece. A first arc-shaped chute is provided on one side where the long overhang is hingedly connected to the bottom plate. A first limiter is fixedly arranged on the upper part, the first arc-shaped chute is sleeved on the first limiter, and a second arc-shaped chute is arranged at the middle end of the bottom plate. The bottom is provided with a second limiting piece, and the second arc-shaped chute is sleeved on the second limiting piece.

It can be seen from the above technical solutions that the present invention is in the form of opening a chute on the long suspension and the bottom plate, through the first arc-shaped chute and the first limiting member, the second arc-shaped The cooperation between the chute and the second limiting piece replaces the original double fulcrum structure or the sliding rail and the sliding block structure. Under the premise of realizing large-angle casement doors and windows, the overall volume is greatly reduced, making the utility model practical The new model is more convenient for installation and production, and at the same time, the smaller volume occupies less space on the doors and windows, which is conducive to the play of the shape design of doors and windows.

Further, a mounting groove and a connecting hole are also provided on the side of the support piece close to the bottom plate, the long suspension and the support piece are hinged on the mounting groove, and are also fixed on the connecting hole. A connecting rod is provided, and a hinge shaft is rotatably provided in the connecting rod, and the short overhang is hingedly connected with the supporting piece through the hinge shaft. From this, it can be seen that the utility model is provided with the connecting rod on the support piece, and the connecting rod is used to connect with the installation groove of the window sash or the door, thereby improving the stability and durability of the connection.

Still further, a square hole is provided on one side of the connecting hole corresponding to the installation slot, and a square clip adapted to the square hole is provided at the bottom of the connecting rod. It can be seen that, through the cooperation between the square hole and the square clip, the direct connection between the connecting rod and the connecting hole is more stable, and the stability of the present invention is effectively improved.

Still further, upper and lower adjustment screws are threadedly connected to the inner side of the upper half of the connecting rod, and a clamping slot is also provided on the outer side of the upper half of the connecting rod. The top of the U-shaped clip is also provided with a connecting screw. It can be seen from this that the present invention adjusts the distance between the connecting rod and the bottom plate through the upper and lower adjusting screws, so as to adjust the distance between the window sash connected with the connecting rod and the window frame, or the distance from the door to the ground. At the same time, the U-shaped clip is used to adjust the verticality between the utility model and the window sash and the window frame, so as to eliminate the hanging foot phenomenon of the window sash.

Still further, a plurality of through holes are arranged on the bottom plate, screws are arranged in the through holes, and a gasket is threadedly connected to the bottom of the screws. It can be seen from this that the spacer is used to increase the distance between the utility model and the window frame during installation, so as to adapt to the width standard of the European standard groove, and the installation can be realized without reducing the width of the bottom plate, which effectively guarantees the utility model. Utility model versatility.

Finally, the long overhang and the short overhang are respectively provided with a first groove and a second groove on one side corresponding to each other, and the first groove is matched with the second groove. It can be seen that, through the cooperation between the first groove and the second groove, when the utility model is in the folded state, the long overhang and the short overhang avoid interference, which further reduces the size of the present utility model. volume in use.
