Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware accessories, specifically to a bidirectional transmission side-mounted handle mechanism. Background Technology

[0002] As one of the main driving components for convenient opening and closing of doors and windows, handles are generally connected to locks or similar structures. This allows the door or window to be opened by mechanically opening the latch or bolt. However, most existing handles are installed on the front of the window, taking up space and requiring a large gap between the inner and outer sides of the window sash. This makes them unsuitable for some profiles with narrow inner and outer thicknesses, and their concealment after installation is poor. Furthermore, the lock box of a side-mounted handle mechanism cannot meet the requirement of bidirectional transmission. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a bidirectional transmission side-mounted handle mechanism, which enables the handle mechanism to be installed on the side of the window profile while achieving bidirectional transmission, and has high concealment after installation.

[0004] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution:

[0005] A bidirectional transmission side-mounted handle mechanism includes a base, a handle disposed on the base, a drive mechanism disposed within the base, a lock box, and a bidirectional transmission mechanism disposed within the lock box and linked to the drive mechanism. The bidirectional transmission mechanism controls the drive mechanism to achieve bidirectional synchronous telescopic sliding through the handle. The handle is disposed on the side of the base and the lock box.

[0006] Preferably, the bidirectional transmission mechanism includes a first transmission rod and a second transmission rod, a rack I disposed on the first transmission rod or the second transmission rod, and two third gears disposed between the first transmission rod and the second transmission rod. The sides of the first transmission rod and the second transmission rod are each provided with rack II that meshes with the third gears. The bidirectional transmission mechanism meshes with the drive mechanism through the rack I.

[0007] Preferably, the lock box includes a base plate and a panel, two rivets disposed between the base plate and the panel for fixing the third gear, and a limiting groove provided on the panel. The rack protrudes outward through the limiting groove and is linked with the drive mechanism.

[0008] Preferably, the limiting groove has inwardly protruding limiting blocks at both ends, the rack is mounted on the first transmission rod, and the second transmission rod has an inwardly protruding structure on one side, and the second transmission rod is limited by the limiting blocks.

[0009] Preferably, trapezoidal protrusions are provided on both sides of the limiting groove.

[0010] Preferably, the drive mechanism includes a first gear disposed on the handle, a second gear disposed in the base and meshing with the first gear, and a third gear meshing with the second gear.

[0011] Preferably, a cover is provided on one side of the base, and the first gear and the second gear are disassembled and assembled through one side of the cover.

[0012] Preferably, a positioning mechanism is provided between the handle and the first gear, and the handle and the first gear are positioned by the positioning mechanism during rotation.

[0013] Preferably, the positioning mechanism includes a washer disposed between the base and the handle, a plurality of springs disposed within the handle, and a plurality of steel balls pressed against one side of the washer by the springs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] It breaks away from the traditional method of installing handles on the front of window profiles, instead installing them on the side of the window profiles. This greatly reduces the thickness gap between the handle and the inner and outer sides of the profile, making it suitable for very narrow window profiles. At the same time, the side mounting provides excellent concealment and saves space. Furthermore, the lock box of this side-mounted handle mechanism can achieve bidirectional transmission, enabling the handle mechanism to achieve bidirectional transmission while installed on the side of the window sash profile, resulting in high concealment after installation.

[0020] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] like Figure 1 As shown, a bidirectional transmission side-mounted handle mechanism includes a base 5, a handle 4 disposed on the base 5, a drive mechanism 2 disposed in the base 5, a lock box 1, and a bidirectional transmission mechanism 3 disposed in the lock box 1 and linked with the drive mechanism 2. The bidirectional transmission mechanism 3 controls the drive mechanism 2 to achieve bidirectional synchronous telescopic sliding through the handle 4. The handle 4 is disposed on the side of the base 5 and the lock box 1.

[0024] In actual installation, the handle 4 is mounted on the side of the window via the base 5, rather than the front. Simultaneously, the bidirectional transmission mechanism 3 enables the handle 4 to synchronously drive other internal components of the window profile on both sides to move bidirectionally during rotation. This breaks away from the traditional method of mounting the handle on the front of the window profile, instead mounting it on the side. This significantly reduces the thickness gap between the handle and the inner and outer sides of the profile, making it suitable for very narrow window profiles. Furthermore, the side mounting provides excellent concealment and saves space. Additionally, the lock box 1 of this side-mounted handle mechanism enables bidirectional transmission, allowing the handle mechanism to achieve bidirectional transmission while mounted on the side of the window sash profile, resulting in high concealment after installation.

[0025] Further improvements include, for example Figure 2As shown, the bidirectional transmission mechanism 3 includes a first transmission rod 34 and a second transmission rod 33, a rack 35 disposed on the first transmission rod 34 or the second transmission rod 33, and two third gears 32 disposed between the first transmission rod 34 and the second transmission rod 33. The sides of the first transmission rod 34 and the second transmission rod 33 are provided with racks 31 that mesh with the third gears 32. The bidirectional transmission mechanism 3 meshes with the drive mechanism 2 through the racks 35.

[0026] The first transmission rod 34 and the second transmission rod 33 are slidably installed inside the lock box 1. Two third gears 32, meshing with rack 31, are installed between the first transmission rod 34 and the second transmission rod 33. During operation, only one of the first transmission rod 34 or the second transmission rod 33 needs to slide left or right to drive the other transmission rod to slide in the opposite direction via the meshing of rack 31 and the third gear 32. A protruding rack 35 is formed on either the first transmission rod 34 or the second transmission rod 33, which meshes with the drive mechanism 2. When the drive mechanism 2 moves the rack 35, it drives the first transmission rod 34 and the second transmission rod 33 to move relative to each other. The transmission between them is achieved through the third gear 32, increasing operational reliability, service life, and transmission accuracy. The first transmission rod 34 and the second transmission rod 33 adopt an L-shaped structure, which reduces the lateral width between the first transmission rod 34, the third gear 32, and the second transmission rod 33, resulting in a smaller overall installation area.

[0027] A further improvement is made to the lock box 1, which includes a base plate 12 and a panel 11, two rivets 13 disposed between the base plate 12 and the panel 11 for fixing the third gear 32, and a limiting groove 14 provided on the panel 11. The rack 35 protrudes outward through the limiting groove 14 and is linked with the drive mechanism 2.

[0028] The lock box 1 consists of a U-shaped base plate 12 and a panel 11. The third gear 32 is installed between the base plate 12 and the panel 11 by a rivet 13. The rivet 13 serves as a pivot, enabling the gear to be positioned and rotated. A limiting groove 14 is formed on the panel 11. The rack 35 passes through the limiting groove 14 and protrudes outward to be linked with the drive mechanism 2. When the rack 35 is driven, when both sides are in contact with one side of the limiting groove 14, a limiting effect is achieved, preventing excessive movement.

[0029] A further improvement is made in that the two ends of the limiting groove 14 are provided with inwardly protruding limiting blocks 7, the rack 35 is provided on the first transmission rod 34, one side of the second transmission rod 33 is provided with an inwardly protruding structure, and the second transmission rod 33 is limited by the limiting blocks 7; trapezoidal protrusions 6 are provided on both sides of the limiting groove 14.

[0030] The limiting groove 14 has inwardly protruding limiting blocks 7 at both ends, and an inwardly protruding structure on one side of the second transmission rod 33. When the second transmission rod 33 slides laterally through the third gear 32, the combination of this structure and the limiting blocks 7 can play a limiting role, preventing the second transmission rod 33 from moving excessively. Trapezoidal protrusions 6 are formed on both sides of the limiting groove 14. Since the rack 35 protrudes outward in a bent manner, there is an arc transition area between the rack 35 and the first transmission rod 34. In order not to affect the flexibility of sliding, the protrusions on both sides can provide sufficient installation space and better limiting effect, preventing the first transmission rod 34 from shaking during driving.

[0031] A further improvement is that the drive mechanism 2 includes a first gear 22 disposed on the handle 4, a second gear 21 disposed in the base 5 and meshing with the first gear 22, and a third gear 32 meshing with the second gear 21.

[0032] The drive mechanism 2 consists of a first gear 22 and a second gear 21. The first gear 22 and the third gear 32 mesh with the second gear 21, which enables the handle 4 to have sufficient installation height. At the same time, it makes the control of the bidirectional transmission mechanism 3 in the lock box 1 more convenient, and the reliability and accuracy of transmission are higher, and the service life is longer.

[0033] A further improvement is that a cover 8 is provided on one side of the base 5, and the first gear 22 and the second gear 21 are disassembled and assembled through one side of the cover 8.

[0034] A closable cover 8 is installed on one side of the base 5. By removing and installing the cover 8, it is easier to remove and install the first gear 22 and the second gear 21, and the operation is easier.

[0035] Further improvements include, for example Figure 3 As shown, a positioning mechanism 9 is provided between the handle 4 and the first gear 22. The handle 4 and the first gear 22 are positioned by the positioning mechanism 9 during rotation. The positioning mechanism 9 includes a washer 93 between the base 5 and the handle 4, a plurality of springs 91 in the handle 4, and a plurality of steel balls 92 pressed against one side of the washer 93 by the springs 91.

[0036] When the handle 4 rotates on the first gear 22, it can be positioned by the positioning mechanism 9 after rotating to a certain angle, thereby improving the user experience. The inner side of the handle 4 has a groove for installing the spring 91 and the steel ball 92. After installation, one side of the steel ball 92 is pushed outward by the spring 91 and pressed against the side of the washer 93. Generally, the handle 4 has four holes for placing the spring 91 and the steel ball 92.

[0037] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
