Description

Technical Field

[0001] The utility model relates to the field of windows and doors, in particular to a window and door handle. Background Art

[0002] Generally, a handle is provided on a window or door to unlock and open the window or door. The existing handle is installed on the window or door through a base, and the handle can be rotated relative to the base to lock or unlock the window or door.

[0003] In order to prevent mosquitoes, people usually install screen doors or screen windows on the indoor side of doors or windows (such as Figure 1 As shown), the handle 2' is arranged in the narrow space 3' between the door and the screen door or the window and the screen window, and the size of the narrow space 3' depends on the thickness of the window and door profile 1', that is, the height of the handle 2' limits the thickness of the window and door profile 1' so as to obtain a narrow space 3' sufficient to accommodate the handle 2'.

[0004] Therefore, lowering the height of the handle can reduce the thickness of the window and door profiles and thus reduce material consumption. However, due to the current design of the handle, the handle usually has a rotating mechanism disposed in the base, so that the height of the base cannot be further reduced, and thus the height of the handle cannot be improved and reduced in this aspect.

[0005] On the other hand, the rotating mechanism also includes an elastic-retractable mechanism and a limiting part that cooperates with the elastic-retractable mechanism. The cooperation between the elastic-retractable mechanism and the limiting part allows the handle to have a certain torque and provides a feel for the rotation of the handle. When the rotating mechanism, the elastic-retractable mechanism and the limiting part are arranged together in the base, the rotating mechanism has a complex structural layout and is difficult to install.

[0033] Reference Figures 2 to 9A window and door handle comprises a handle 2 and a mounting base 1. The mounting base 1 is protruded with a through sleeve 3. The back of the handle 2 is provided with a sleeve cavity 4 that cooperates with the sleeve 3. A rotating shaft 5 extends out of the sleeve cavity 4. The rotating shaft 5 penetrates into the sleeve 3 to realize the rotational installation of the handle 2 and the mounting base 1. At the same time, the sleeve 3 extends into the sleeve cavity 4, which greatly reduces the installation height between the handle and the mounting base 1. The elastic shrinkage mechanism is arranged on the side wall of the sleeve cavity 4 of the handle 2. The outer side wall of the sleeve 3 is provided with a limiting structure that cooperates with the elastic shrinkage mechanism, so that the structure of the mounting base 1 is simplified and the height of the body of the mounting base 1 is reduced. Through the cooperation of the above two elements, the height of the handle is greatly reduced, thereby reducing the thickness of the window and door profile, achieving the purpose of reducing the consumption of profile materials and reducing the manufacturing cost. Since the elastic shrinkage mechanism is arranged on the handle, and the limiting structure that cooperates with the elastic shrinkage mechanism is arranged in the sleeve as an integral arrangement, the parts are simplified and the arrangement of the rotation limiting structure is completed while the handle is installed, and the assembly process is simpler.

[0034] The retractable mechanism and the limiting structure can realize the rotational positioning of the handle 2 when it is rotated through the concave-convex cooperation, so that the user can clearly know that the handle 2 is rotated into place and unlocked or locked, and in the unlocked or locked state, it brings a certain torque to the handle to prevent the handle from easily rotating due to factors such as gravity or slight touch and losing the current state, which is more conducive to the user's next use operation. As a preferred embodiment of the present utility model, the limiting structure includes more than two limiting grooves 6 distributed around the outer wall of the sleeve 3, and the retractable mechanism is provided with an elastically retractable elastic member 7 that cooperates with the limiting groove 6, that is, when the elastic member 7 is inserted into the limiting groove 6, the rotation of the handle 2 is limited, so that the handle 2 is known to be rotated into place. Furthermore, the limiting groove 6 can have more, such as Figure 6 As shown, there are four limiting grooves 6 evenly distributed around the outer wall of the sleeve 3, so that the handle 2 can trigger the cooperation between the elastic and retracting mechanism and the limiting structure when it is turned left or right, making the installation adaptability of the utility model higher. On the basis of the four limiting grooves 6, small grooves (not shown in the figure) can be further added between each limiting groove 6, but the depth of the small grooves will be shallower than that of the limiting grooves 6, and the elastic member 7 will bring a good operating feel to the user when passing through these small grooves.

[0035] The elastic member 7 can be implemented in two ways: a marble 71 or a spring sheet 72. The utility model preferably adopts the marble 71 solution, and the marble 71 can roll out of the limiting groove 6, making the user's operation more labor-saving.

Further, in order to more conveniently arrange the marble 71, a mounting cavity 9 is arranged in parallel on the side of the sleeve cavity 4, an opening 91 is provided between the mounting cavity 9 and the sleeve cavity 4, a receiving box 8 is detachably installed in the mounting cavity 9, the mounting channel 81 is formed in the receiving box 8, and the opening of the mounting channel 81 is exposed in the sleeve cavity 4 through the opening 91; through the above structure, the marble 71 can be assembled externally and then installed in the handle 2, simplifying the assembly process. Furthermore, the sleeve cavity 4 is disposed at the end of the handle 2, and the sleeve cavity 4 and the mounting cavity 9 are arranged along the axis of the handle 2 to avoid occupying the space in the width direction of the handle 2, so that the handle 2 is designed to be slim and easier to hold.

[0037] like Figure 5 In the second embodiment of the elastic member 7 shown, when a spring sheet 72 is used, the root of the spring sheet 72 is embedded in the side wall of the sleeve cavity 4, and the spring sheet 72 can elastically move out of the limiting groove 6 by deformation.

[0038] The connection structure of the handle 2 and the mounting base 1 and the arrangement of the elastic and retractable mechanism can be applied to different window and door handles. For example:

[0039] like Figures 3 to 5 As shown, it is applied to a transmission handle that needs to be connected to the lock body in the window and door. The sleeve 3 is arranged through, and a transmission hole 52 is provided in the rotating shaft 5. The transmission hole 52 is connected to the transmission shaft through the bottom opening of the sleeve 3 and the lock body in the window and door. By rotating the handle 2, the lock body in the window and door can be driven to work to achieve locking or unlocking of the window and door. A metal gasket 13 is provided below the bottom opening of the sleeve 3, and a bending portion 51 is provided at the end of the rotating shaft 5. After the rotating shaft 5 passes through the bottom opening of the sleeve 3 and the metal gasket 13 in turn, it is bent outwards through the bending portion 51 to abut against the bottom of the metal gasket 13, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3.

[0040] like Figure 8 , Fig. 9 As shown, or applied to another locking handle that only locks the window frame or door frame through the tongue 21, the handle 2 is provided with a tongue 21, the axis of the tongue 21 intersects with the axis of the handle 2 and the axis of the rotating shaft 5, and the window frame or door frame is also provided with a pad that abuts against the tongue 21 to achieve locking; specifically, the tongue 21 is arranged on the side wall of the end of the handle 2, and the rotation of the handle 2 drives the tongue 21 to move to lock the window frame or leave the window frame to unlock.

[0041] Preferably, mounting holes 11 for mounting with windows and doors are respectively provided at both ends of the mounting base 1, and a decorative cover 10 is also installed on the front of the mounting base 1 to cover the mounting holes 11, improve the appearance of the handle, and protect the screws in the mounting holes 11. Furthermore, the sleeve cavity 4 is open and protrudes from the back of the handle 2 to form a ring platform 41, which, on the one hand, allows more space to be reserved between the handle 2 and the window and door for hand operation, and on the other hand, an elastic gasket 12 is provided between the bottom surface of the ring platform 41 and the top surface of the decorative cover 10, so that the decorative cover 10 can manually overcome the elastic force of the elastic gasket 12 and leave the mounting base 1, and the mounting hole 11 can be exposed by rotation, which is more conducive to the installation of the handle by the user.
