Description

Technical Field

[0001] This utility model relates to the technical field of casement door and window accessories, and in particular to a casement door and window handle. Background Technology

[0002] Casement door and window handles are devices installed on doors and windows, serving to secure them after opening and closing. They are an indispensable accessory for casement doors. A set consists of two handles, installed on the interior and exterior sides of the door. A base covers the lock body between the two handles. Turning the handles activates the bolt in the lock body via a square shaft, thus unlocking the door. The basic functions are the rotation and return of the handle to its original position. However, existing handle components are numerous and complex to install. First, a coil spring is placed inside the cavity of the handle or base to return the handle to its original position. Because of the coil spring, corresponding notches need to be made in the cavity walls of the handle and base. During installation, one cavity must fit into the other, with the two notches overlapping so that the two ends of the coil spring rest on... The notch at both ends allows the handle to rotate on the base, and the spring automatically returns the handle to its original position after release. The cavity and notch are fixed to the handle or base, requiring alignment of the handle and the notch on the base for each installation. This results in a single orientation for the handle, leading to insufficient flexibility. If the handle is installed in the wrong orientation, the notch cannot be aligned with the notch on the base, making installation impossible and resulting in low efficiency. Alternatively, the cavity and handle can be made into a separate structure, connecting the cavity to the base first, and then installing the handle as needed, allowing for a more flexible orientation. However, this structure involves many parts, high processing costs, and requires multiple steps to complete the installation, without improving efficiency. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As shown in the attached figure, this utility model discloses a casement door and window handle, comprising two handles 1 and a panel 2. Each of the two handles 1 is provided with a groove 10, and the two walls of the groove 10 are symmetrically provided with arc-shaped walls 11. Specifically, the groove 10 protrudes from the front and rear sides in the width direction of the handle 1 to form arc-shaped walls 11, and a channel is formed between the two arc-shaped walls 11. A bushing 12 is provided protruding from the middle of the channel. Each of the two panels 2 has a through hole 200, and two fan ring plates 21 corresponding to the arc-shaped walls 11 are provided protruding from one side. A coil spring 3 is provided between the two fan ring plates 21, and an opening is formed between the ends of the two fan ring plates 21. The bushing 12 passes through the through hole 200 and is fixed by a locking piece 123. The two panels 2 are respectively placed on both sides of the door, and each of the two panels 2 is provided with mounting holes. The two panels 2 are fixedly connected by screws. This belongs to the existing handle installation structure.

[0021] This utility model discloses a casement door and window handle, which is installed by cooperating with two symmetrically arranged arc-shaped walls 11 inside the handle 1 and two symmetrically arranged ring plates 21 on the panel 2. Since the ends of the two ring plates 21 are not connected, two openings are formed at the two ends of the corresponding channel, allowing the handle 1 to be installed upright or backward on the panel 2. Both ends of the coil spring 3 can overlap the two ends of the same ring plate 21, improving the flexibility of installation. At the same time, it simplifies the overall structure of the handle, with fewer parts and easy installation. The handle 1 and the panel 2 are integrally molded structures, effectively controlling production costs. Moreover, whether the handle 1 is installed upright or backward, the arc-shaped walls 11 on it can be aligned with the ring plates 21 for installation. Furthermore, openings are formed at the ends of the two ring plates 21, allowing the ends of the coil springs 3 to extend and abut against the ends of the ring plates 21 and the arc-shaped wall 11. Workers can install the handle 1 without checking its orientation. First, the coil spring 3 is placed into the ring plate 21 of the panel 2, with both ends of the coil spring 3 abutting against one of the ring plates 21. Then, the panel 2 and the handle 1 are combined and twisted left and right, so that both ends of the coil spring 3 in the panel 2 also abut against the arc-shaped wall 11 corresponding to the handle 1. Installation can be completed in just two steps, improving installation efficiency. At the same time, the opening on the panel 2 corresponds to the existing notch, and the channel opening on the handle 1 also corresponds to the existing notch, so it can be used to replace the current panel 2 or handle 1.

[0022] In this embodiment, the two fan ring plates 21 are set inside the corresponding arc-shaped walls 11. The centers of the fan ring plates 21, the arc-shaped walls 11, the bushings 12, and the through holes 200 are all set on the same center line. The outer arc surface of the fan ring plate 21 corresponds to the inner arc surface of the arc-shaped walls 11, and the included angle of the fan ring plate 21 is the same as the included angle of the arc-shaped walls 11. After installation, the two fan ring plates 21 correspond to the two arc-shaped walls 11, and the coil spring 3 is located between the two fan ring plates 21 and is sleeved on the outside of the protruding bushings 12. The bushings 12 pass through the through holes 200 and are fixed by the locking piece 123, so that the handle 1 can rotate with the bushings 12 as the center.

[0023] In this embodiment, the ends of the coil spring 3 abut against one of its ring plates 21 and the end of the arc-shaped wall 11 corresponding to the ring plate 21. The two ends of the coil spring 3 abut against the two ends of one of its ring plates 21 and the two ends of the arc-shaped wall 11. When the handle 1 is rotated, the arc-shaped wall 11 rotates relative to the ring plate 21, and at the same time, the arc-shaped wall 11 pushes one end of the coil spring 3 to compress. When the hand is released, the handle 1 automatically returns to its original position due to the self-rebound of the coil spring 3. The bottom of the groove 10 is provided with an anti-wear layer 100. The anti-wear layer 100 mainly prevents the handle 1 from being worn when the coil spring 3 moves, and at the same time makes the movement of the coil spring 3 smoother. The anti-wear layer 100 is a metal gasket. The panel 2 is also provided with a boss, and the two ring plates 21 are provided on the two symmetrical edges of the boss. The through hole 200 is located in the middle of the boss.

[0024] In this embodiment, the end face of the bushing 12 is provided with a insertion groove 120 and an annular groove 121 is provided on the outer side. The locking piece 123 is engaged in the annular groove 121. The insertion groove 120 is used to insert the rotating shaft and drive the lock body using the rotating shaft. This is an existing structure and will not be described in detail. The locking piece 123 is located on the side of the panel 2 away from the fan ring plate 21. After the bushing 12 passes through the through hole 200, the locking piece 123 is engaged in the annular groove 121 to fix it, thereby fixing the handle 1 and the panel 2 without affecting the rotation of the handle 1 on the panel 2.

[0025] In this embodiment, the panel 2 is provided with an opening 201, and the handle 1 is slidably connected to a pin 40 corresponding to the opening 201 and a slide plate 41 for pushing the pin 40 to extend and retract within the opening 201. The slide plate 41 is slidably connected to the handle 1 and is provided with a push button 402 protruding from the outside of the handle 1. This is a deadbolt structure for the handle. By pushing the push button 402, the pin 40 is pushed into the opening 201, thereby preventing the handle 1 from rotating on the panel 2. This deadbolt structure can refer to existing handle structures. Specifically, the pin 40 and the opening 201 are both located at the eccentric part of the rotation center. The side of the slide plate 41 facing the pin 40 is provided with a protrusion and a ramp. When the slide plate 41 is pushed, its ramp gradually pushes the pin 40 toward the opening 201. Furthermore, the opening 201 can directly refer to the mounting hole without the need for additional drilling. Based on this, the slide plate 41 is provided with a strip groove 401, and the handle 1 is provided with a connection hole 411 corresponding to the strip groove 401. The handle 1 is screwed through the strip groove 401 and threadedly connected to the connection hole 411. The slide plate 41 is clamped by the screw and the handle 1. At the same time, the screw and the strip groove 401 are slidably connected. The screw is used for positioning to ensure that the slide plate 41 slides in a straight line.

[0026] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
