Description

Technical Field

[0001] This utility model relates to the technology of doors and windows, and in particular to a side-mounted control transmission system for doors and windows, which is mainly but not limited to casement windows with narrow side panels, sliding windows / doors with narrow side panels, casement windows / doors with fully concealed side panels, and sliding windows / doors with fully concealed side panels. Background Technology

[0002] In the current window and door industry, narrow-frame and fully concealed sashes are increasingly popular with consumers due to their wider field of vision and larger light-transmitting area. However, because these sashes have a very narrow visible width, there isn't enough space to install handles. Therefore, some manufacturers use side-mounted actuators. However, existing side-mounted actuators and handles on the market are often custom-designed to match specific styles at the factory, making them difficult to replace with other styles or handles from other manufacturers. This results in poor versatility and difficulty in replacement. Especially when customers dislike a particular handle style, they may abandon narrow-frame windows and doors. Thus, this hinders the development of narrow-frame and fully concealed windows and doors, and prevents further increases in their market share.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a side-mounted control transmission system for doors and windows. By designing a side-mounted control transmission system with a converter to connect to commonly used square shaft handles on the market, the present invention enables the side-mounted control transmission system to be interchangeable with conventional square shaft handles on the market, thus solving the problems of limited handle styles and inconvenient replacement in existing side-mounted door and window control transmission systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0040] See attached document Figures 1 to 17 A side-mounted control transmission system for doors and windows includes a housing 10, a converter 20, a bidirectional actuator 30, and a sash profile 40. The housing 10 includes a mounting portion 11 and a protrusion 12 extending from one side of the mounting portion 11. The protrusion 12 has a mounting cavity, and the mounting cavity is open on the side adjacent to the mounting portion 11. During installation, the converter 20 extends into the mounting cavity from the opening, such that a portion of the converter 20 (first gear 221) is located within the mounting cavity. The side of the sash profile 40 has a mounting position corresponding to the mounting portion 11 of the housing 10, and the housing 10 is mounted at the mounting position. During installation, the housing 10 is installed starting from the side of the sash profile 40, and the protrusion 12 is located on the sash profile 40, protruding towards the glass side of the sash profile 40. It should be noted here that: the side of the fan-shaped profile 40 mentioned in this article refers to the left or right side of the fan-shaped profile 40; the front (or viewing side, also called the front side) of the fan-shaped profile 40 is the side viewed from inside to outside; and the back (or rear side) of the fan-shaped profile 40 is the side viewed from outside to inside. Wherein:

[0041] The converter 20 includes a support base 21 and a transmission module 22 mounted on the support base 21. The transmission module 22 has a handle mounting hole 201 for connecting with the handle and a transmission component 202 for connecting with the bidirectional transmission 30. The housing 10 is provided with a clearance hole 101 corresponding to the handle mounting hole 201. At the same time, the housing 10 is also provided with a mounting structure 102 for connecting with the handle base.

[0042] The mounting structure 102 is typically a screw hole, and during installation, the base of the handle is connected to the screw hole via connecting screws; of course, the mounting structure 102 can also be a snap-fit ​​structure, which enables the handle to be detachably connected; or, the mounting structure 102 can be welded, glued, etc., which will not be listed here.

[0043] The handle mounting hole 201 is preferably a square shaft hole. The transmission component 202 can be a cylindrical pin, and the transmission position 31 is a shift fork adapted to the cylindrical pin.

[0044] Thus, by providing the handle mounting hole 201 and the mounting structure 102, the side-mounted control transmission system of this embodiment can install commercially available square shaft handles, solving the problem that traditional side-mounted control transmission systems can only install customized handles, and addressing the issues of limited design and difficulty in replacement of existing products. It should be noted that the two main types of square shaft handles commonly found on the market are: 1. Exposed base square shaft handles (commonly referred to as base-supported square shaft handles in the industry); 2. Concealed base square shaft handles (commonly referred to as baseless square shaft handles in the industry). Both types of square shaft handles can be connected to the side-mounted control transmission system of this specification. During connection, the square shaft of the square shaft handle is inserted into the handle mounting hole 201, and the base of the square shaft handle is connected to the mounting structure 102 via connecting screws.

[0045] The bidirectional transmission device 30 has a transmission position 31 adapted to the transmission component 202. During installation, the transmission component 202 is located in the transmission position 31. The fan-shaped profile 40 is preferably an aluminum profile. It should be noted that the transmission position 31 mentioned here is merely a name for the corresponding component and does not limit its specific shape; for example, the transmission position 31 in this embodiment can be as follows: Figure 15 The groove-shaped structure shown can also be as follows: Figure 16 The protruding structure shown is not specifically limited here; it only needs to satisfy the transmission cooperation with the transmission component 202.

[0046] Specifically, the transmission module 22 includes a first gear 221, a second gear 222, and a rack 223. The handle mounting hole 201 is disposed on the first gear 221, and the transmission component 202 is disposed on the rack 223. The support base 21 is also provided with a vertical sliding groove, and the rack 223 is slidably mounted on the vertical sliding groove. Preferably, the support base 21 has a first clamping plane 211, and the outer shell 10 has a second clamping plane 103. During installation, a gap is maintained between the first clamping plane 211 and the second clamping plane 103 to form a clamping gap. The fan-shaped profile 40 has a clamping side 41 (e.g., ...) that matches the clamping gap. Figure 17 (as shown); the clamping gap is used to lock the clamping side to securely install the converter 20, housing 10 and fan profile 40.

[0047] Furthermore, the support base 21 includes a first support plate 212 and a second support plate 213. The first support plate 212 has a fastening post 2121, and the second support plate 213 has a fastening hole 2131. The fastening post 2121 is fastened to the fastening hole 2131, thereby completing the assembly of the first support plate 212 and the second support plate 213. An installation area is maintained between the first support plate 212 and the second support plate 213, and the first gear 221 and the second gear 222 are both installed in the installation area. Thus, the partitioning is reasonable, achieving a large transmission distance within a limited space. The overall structure is compact, the transmission is smooth, and it is suitable for smaller fan profiles 40, thereby reducing the material used in the fan profile 40, lowering costs, and being more environmentally friendly.

[0048] Preferably, the buckle 2121 can be a rivet, which directly and securely assembles the first support plate 212 and the second support plate 213 through a riveting structure, thereby improving assembly stability and assembly efficiency.

[0049] The aforementioned first clamping plane 211 is disposed on the first support plate 212. Specifically, the first support plate 212 has clamping ribs extending outward, and the first clamping plane 211 is disposed on the clamping ribs. In this embodiment, there are four clamping ribs, and the second clamping plane 103 is located on the side of the outer shell 10 facing the fan profile 40. Thus, the clamping side 41 of the fan profile 40 is clamped by the first clamping plane 211 of the four clamping ribs and the second clamping plane 103 of the outer shell 10, ensuring the stable assembly of the fan profile 40, the converter 20 and the outer shell 10.

[0050] Furthermore, the first support plate 212 is provided with a first guide groove 2122 corresponding to the vertical slide groove, and the second support plate 213 is provided with a second guide groove 2132 corresponding to the vertical slide groove. The first guide groove 2122 and the second guide groove 2132 are arranged parallel to each other. The rack 223 is provided with a first guide protrusion adapted to the first guide groove 2122 and a second guide protrusion adapted to the second guide groove 2132. During installation, the first guide protrusion is located in the first guide groove 2122, and the second guide protrusion is located in the second guide groove 2132. In this way, the smoothness of the rack 223's movement within the vertical slide groove is further improved by the arrangement of the guide grooves and guide protrusions. It can be added here that the rack 223 typically moves 17mm within the vertical slide groove to meet working requirements; of course, it can also be adjusted according to actual needs, and no specific limitation is made here.

[0051] Furthermore, the bidirectional transmission 30 includes a base shell 32, a C-groove panel 33, a first transmission rod 34, a second transmission rod 35, and a rivet shaft 36. The C-groove panel 33, the first transmission rod 34, the second transmission rod 35, and the rivet shaft 36 are all mounted on the base shell; this is prior art and will not be elaborated upon here. In use, the transmission components 202 and 31 cooperate to achieve the transmission connection between the converter 20 and the bidirectional transmission 30. Further, the outer shell 10 has a first connecting hole 104 for connecting with a profile, a second connecting hole 105 for connecting with a support base 21, and a third connecting hole 106 for connecting with the bidirectional transmission 30.

[0052] The following is a more detailed description of the production and assembly process:

[0053] Step 1: Drill holes on the side of the fan profile 40 to form the aforementioned mounting position (e.g., Figure 7 );

[0054] Step 2: As Figures 7 to 9 As shown, connecting screws are used to pass through the side of the fan profile 40 (commonly referred to in the industry as the C-groove surface of the fan profile 40) to the first connecting hole 104, thereby locking the housing 10 onto the fan profile 40.

[0055] Step 3: As Figures 10 to 12 As shown, the converter 20 is further inserted into the housing 10 from the C-groove surface, and the connecting screw is passed through the support base 21 (second support plate 213) to the second connecting hole 105, thereby completing the installation and locking of the converter 20 and the housing 10. It should be noted that the first clamping plane 211 of the converter 20 and the second clamping plane 103 of the housing 10 simultaneously clamp the fan profile 40, making the connection between the housing 10 and the fan profile 40 more stable.

[0056] Step 4: As Figures 13 to 15 As shown, the bidirectional drive 30 and the converter 20 are inserted into each other, and the drive component 202 of the converter 20 is positioned in the drive position 31. Finally, the installation is completed by passing the connecting screw through the third connecting hole 106 of the bidirectional drive 30, the fan profile 40 and the housing 10.

[0057] The key design feature of this invention is that it incorporates a converter to connect to commonly used square shaft handles on the market, thereby enabling the control transmission system of this invention to be compatible with conventional square shaft handles and solving the problem of single handle and difficulty in replacement in existing side-mounted door and window control transmission systems.

[0058] Secondly, the converter of this utility model has a compact internal structure and smooth transmission. At the same time, the control transmission system of this application adopts a side-mounted method, which can narrow the visible surface of the fan profile, save materials, and is more environmentally friendly; it can be made into a narrow-faced or fully concealed fan, improving the visual effect.

[0059] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
