Description

The upper pulley device, hardware system and side-pressure sliding doors and windows Technical Field

[0001] This utility model belongs to the field of door and window technology, specifically relating to an upper pulley device, hardware system, and side-pressure sliding door and window. Background Technology

[0002] In existing side-pressure sliding door and window hardware systems, the translational transmission of the upper pulley often requires connection with a corner bracket. This not only increases the complexity of the entire hardware system and installation time, but also causes the upper pulleys at both ends of the door and window sash to move away from the left and right ends of the door and window sash after the upper pulleys are connected to the corner bracket (see Figure 1). This results in an increase in the amount of shaking of the door and window sash. Furthermore, since the four corners of the door and window sash are where the profiles and rubber strips are assembled and transferred, the overall sealing performance is relatively weak. Therefore, the upper pulleys moving away from the left and right ends of the door and window sash will not be conducive to improving the sealing performance of the door and window sash.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0049] Example 1

[0050] Referring to Figures 2-14, this embodiment discloses an upper pulley device for a side-pressure sliding door and window, including a base 1, a slide 2, and a translation drive assembly.

[0051] The base 1 is fixed to the door and window frame 9 and installed in the side groove (left or right side) of the door and window frame 9; the slide 2 is slidably mounted on the base 1, and a guide structure is provided between the slide 2 and the base 1 to guide the slide 2 to move relative to the base 1 along the thickness direction of the door and window frame (i.e., the left and right direction in Figures 8 and 9, or the inward and outward direction of the door and window sash); one end of the slide 2 is connected to a pulley 3, which extends out of the base 1 and is located in the groove of the fixed frame 10.

[0052] The translation drive assembly includes a drive member 5 and a sliding member 6; the drive member 5 moves with the transmission component 4 of the hardware system. The drive member 5 is provided with a drive groove 501, and the sliding member 6 is disposed on the slide block 2 and embedded in the drive groove 501 and can slide along the drive groove 501. In this embodiment, the extension direction of the drive groove 501 is inclined to the moving direction of the drive member 5, so that when the sliding member 6 slides along the drive groove 501, it drives the slide block 2 to translate relative to the base 1, as shown in FIG5. In order to improve the stability of the upper pulley device at the locking and opening points, curved positions can be provided at both ends of the drive groove 501, or the drive groove 501 can be roughly serpentine or S-shaped.

[0053] When the transmission component 4 of the hardware system drives the drive component 5 to move, the sliding component 6 slides in the drive groove 501. At the same time, under the guidance and limitation of the guide structure, the slide 2 is prompted to move relatively relative to the base 1, so as to achieve the purpose of locking or opening the door and window sash.

[0054] The guide structure in this embodiment can be implemented using a plurality of protrusions 201 and a plurality of grooves 102. The grooves 102 extend along the thickness direction of the door / window frame, and each protrusion 201 is correspondingly embedded in each groove 102. The number of protrusions 201 and grooves 102 in this embodiment can be flexibly adjusted according to actual conditions, but at least two are generally preferred; for example, this embodiment uses three protrusions 201 and three grooves 102. Furthermore, in this embodiment, the protrusions 201 are disposed on the slide 2, and the grooves 102 are disposed on the base 1. Alternatively, the protrusions 201 can be disposed on the base 1, and the grooves 102 on the slide 2.

[0055] By designing a guide structure, the translational direction of the slide 2 can be restricted and guided, and the stability and reliability of the slide 2 during relative translation with the base 1 can be improved. In this embodiment, a protrusion is provided on the slide 2 and a groove 102 is provided on the base 1.

[0056] In this embodiment, the driving component 5 is plate-shaped; the sliding component 6 protrudes from one side of the slide block 2. The sliding component 6 in this embodiment can be a pin, a column, or a similar shape to allow it to slide in the driving groove 501. The sliding component 6 can be integrally formed with the base 1 or it can be a separate component assembled in the slide block 2. This embodiment uses the sliding component 6 as a separate component, shaped like a pin. The slide block 2 has holes for the sliding component 6 to be inserted into, thus enabling the sliding component 6 to drive the slide block 2 to move horizontally. This design is simple and easy to assemble.

[0057] To facilitate the connection between the driving component 5 and the transmission component 4, the driving component 5 in this embodiment is provided with a connecting portion 502 for connecting with the transmission component 4 of the hardware system. The connecting portion 502 is in the form of a through hole, a groove 102, or a protrusion. Specifically, since the driving component 5 in this embodiment adopts a plate-like structure, a through hole or groove 102 structure can be provided on the driving component 5, which is convenient for processing. The through hole or groove 102 facilitates the assembly with the transmission component 4 so that they can move synchronously. Correspondingly, a protrusion structure 401 can be provided on the transmission component 4.

[0058] Furthermore, the transmission component 4 of the aforementioned hardware system can be the transmission bar of the lock actuator, or the intermediate connecting part 502 connected to the transmission bar, so as to enable the transmission component 4 of the hardware system to drive the driving component 5 to move synchronously.

[0059] Furthermore, in this embodiment, the base 1 is provided with a sliding cavity 101, and the slide 2 is located in the sliding cavity 101. The sliding cavity 101 has an opening 1011 near the fixed frame 10 for the pulley 3 to pass through. The driving component 5 is also located in the sliding cavity 101. The sliding cavity 101 provides an installation space for the slide 2, and the groove 102 of the guide structure in this embodiment is also provided in the sliding cavity 101, facilitating the assembly of the slide 2 and the base 1, and contributing to a more compact and reliable structure. Simultaneously, the driving component 5 is located in the sliding cavity 101, and the sidewall of the sliding cavity 101 can be used to restrict and guide the driving component 5, improving the movement stability of the driving component 5. Under user control, the transmission component 4 generally moves linearly, and therefore the driving component 5 connected to the transmission component 4 will also move linearly. In this embodiment, the sidewall of the sliding cavity 101 on the base 1 further guides and limits the driving component 5, which helps to improve the translational stability of the driving component 5 and the entire pulley device.

[0060] Furthermore, a protective plate 8 is provided on the base 1, which covers the sliding cavity 101. The protective plate 8 protects and prevents dust from entering the sliding cavity 101 during installation or use, thus preventing damage to the components.

[0061] In this embodiment, the end of the slide block 2 near the fixed frame 10 extends out of the base 1, and the pulley 3 is connected to the end of the slide block 2 near the fixed frame 10 via the mounting bracket 7. Furthermore, in this embodiment, the mounting bracket 7 and the end of the slide block 2 can be assembled using accessories such as pins, rivets, bolts, and screws, which is convenient, quick, and allows for disassembly.

[0062] This embodiment also discloses a hardware system, including a handle, a transmission mechanism, and an upper pulley device for side-pressing sliding doors and windows. Generally, two upper pulley devices are provided on the sliding door / window frame 9, located on the left and right sides of the frame 9 respectively. The accompanying drawings in this embodiment illustrate the upper pulley device located on the left side; the upper pulley device located on the right side can be referenced accordingly.

[0063] This embodiment also discloses a side-pressure sliding door and window, including a door and window sash frame 9, a fixed frame 10, and a hardware system.

[0064] Example 2

[0065] The difference between this embodiment and embodiment 2 is that, in this embodiment, the drive groove 501 is disposed on the slide block 2, and the sliding member 6 is disposed on the drive member 5 and embedded in the drive groove 501 and can slide along the drive groove 501. In this way, the slide block 2 can be moved relative to the base 1 by the cooperation of the sliding member 6 and the drive groove 501.

[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
