Description

Technical Field

[0001] This utility model relates to the technical field of side-pressure doors and windows, and in particular to a sunken drainage structure for a side-pressure sliding window. Background Technology

[0002] Side-pressure windows are based on sliding windows where the sash moves laterally. When closed, the sash compresses inward / outward by a few millimeters, pressing against the sealing strip of the window frame. This design not only improves the window's sealing performance but also enhances its wind pressure resistance. Its thermal break design, combined with floor-to-ceiling panoramic glass, provides both sound and heat insulation while maintaining transparency and brightness.

[0003] Referring to existing side-pressure windows, they mainly consist of a window frame and a window sash. The window frame has guide rails spaced along its thickness for the window sash to slide, as well as slots for fixing the glass. Side-pressure plates or cover plates are also installed on the window frame, and sealing strips are placed on these plates. When side-pressure occurs, the window sash side panel presses against the sealing strip. The exterior surface of the guide rails has a recessed structure. Furthermore, most existing side-pressure windows do not have a drainage structure on the bottom track; they rely on the window's own sealing performance to keep rainwater out. However, in heavy rain... In some cases, rainwater will still seep into the sealing strip, or after prolonged use, the sealing strip is prone to aging and damage after being repeatedly pressed. Rainwater will then accumulate in the recessed structure through the sealing strip and cannot be discharged. Some side-pressure windows will directly open an opening in the recessed structure and open a drainage hole on the outside side of the window frame. The rainwater is first introduced into the inner cavity of the profile and then allowed to flow along the inner cavity to the drainage hole for discharge. However, such drainage structure has defects. The drainage speed is too slow and it is difficult to drain the water completely. Rainwater is easy to accumulate in the inner cavity of the profile.

Detailed Implementation

[0018] 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.

[0019] As shown in the attached diagram, this utility model discloses a recessed drainage structure for a side-pressing sliding door / window, comprising a lower rail profile 1 and an installation platform 2. A baffle is provided on the front side of the top of the lower rail profile 1, and a guide rail 3 protrudes from the rear side. The baffle is typical of existing side-pressing window structures, generally located on the front or rear side. The upper rail profile and side frame profile also have baffles. Specifically, in this technical solution, the opening sash 30 is located on the rear side, and the baffle is located on the front side of the lower rail profile 1. An installation platform 2 is provided between the guide rail 3 and the baffle. A drainage channel 4 is provided below the installation platform 2, and the baffle is connected to the drainage channel. The drainage channel 4 has an inclined surface 41 that gradually slopes downward from back to front. The sunken drainage channel 4 formed between the mounting platform 2 and the top surface of the lower rail profile 1 is conducive to guiding rainwater to the area below the mounting platform 2 and discharging it along the inclined surface 41 towards the drainage outlet. The mounting platform 2 is provided with openings A 21, B 22 and C 23 connected to the drainage channel 4 from front to back. Rainwater can enter the drainage channel 4 through multiple openings. Openings are set at possible water ingress positions to achieve more comprehensive drainage and cleaner drainage.

[0020] This utility model discloses a sunken drainage structure for a side-pressure sliding door and window. By setting a sunken drainage channel 4 below the installation platform 2, rainwater is guided to flow quickly downward to the drain outlet using the inclined surface 41, and then discharged outside the window through the drain outlet, achieving rapid drainage. At the same time, the provided installation platform 2 is used to install and fix the glass 50 and the cover plate 5, etc. Lifting the fixed glass 50 for installation does not affect the drainage of the drainage channel 4 below, and effectively increases the height of the drainage channel, thereby increasing the water storage volume of the drainage channel, which can hold more infiltrated rainwater and prevent rainwater backflow. Moreover, the more rainwater is held, the faster it can be pushed out along the slope of the inclined surface 41 by its gravity, which is conducive to rapid and clean drainage. At the same time, the rainwater flows out of the drain outlet from the drainage channel 4 and does not enter the inner cavity of the profile, improving the water tightness of the entire window.

[0021] In this embodiment, the lower rail profile 1 is divided into a fixed area and a movable area from front to back. This belongs to the existing side-pressure window structure. The fixed area is used to install the fixed glass 50 and the cover plate 5, and the movable area is used to install the operable sash 30 and provide a space for the operable sash 30 to move. The A opening 21 and B opening 22 are located in the fixed area, and the guide rail 3 is located in the movable area. According to the existing structure description, the installation methods of the fixed glass 50 are mainly extrusion and glue. After installation, there is a possibility of water ingress in the gap between the fixed glass 50 and the glue strip. Therefore, the A opening 21 and B opening 22 correspond to the gaps where the fixed glass 50 abuts against the glue strip on the front / back side. The baffle is connected to the cover plate 5, and the cover plate 5 is provided with a sealing strip 51. The C opening 23 and the sealing strip 51 are vertically aligned. When the operable sash 30 is closed, the sealing strip 51 on the cover plate 5 will abut against the operable sash 30. Water may also enter through the gap between the operable sash 30 and the sealing strip 51. Therefore, opening C 23 is set below the sealing strip 51 to drain rainwater entering through the gap between the sealing strip 51 and the operable sash 30. The drainage paths of the fixed area and the movable area are connected, making the drainage of the entire window faster and smoother, thereby increasing the water storage volume. That is, the length of the drainage channel is increased to the length of the entire lower rail profile 1, so that it can hold more rainwater and facilitate the drainage of rainwater. Furthermore, an opening can be made on the cover plate 5 to drain the rainwater on the cover plate 5 and introduce it to be discharged first through opening A 21, reducing the rainwater seeping in through the gap between the sealing strip 51 and the operable sash 30 along the cover plate 5.

[0022] In this embodiment, the drainage channel 4 includes a flat portion 42 located at the front end of the inclined surface 41; the guide rail 3 is provided with a buckle portion 33 on the front side, the baffle is provided with a hook portion 111 on the rear side, the mounting platform 2 is provided with a slot 202 that cooperates with the buckle portion 33 on the rear side, and a support bar 201 that abuts against the flat portion 42 is provided at the bottom. The support bar 201 has a notch at the bottom for rainwater to pass through. The inclined surface 41 is provided with an overlapping portion 44 for supporting the mounting platform 2 at the rear end. During installation, the front end of the mounting platform 2 is first placed on the bottom surface of the hook portion 111, and the slot 202 is used to buckle with the buckle portion 33. The support bar 201 abuts against the flat portion 42 to form a support structure, thereby enhancing the support of the mounting platform 2. The lower rail profile 1 can be assembled with the side frame profile 45 degrees. The side frame profile does not need to be provided with a drainage channel 4, and the hole formed by the assembly of the lower rail profile 1 and the side frame profile can be sealed with plastic. The plastic seal can be integrally injection molded according to the shape of the hole.

[0023] In this embodiment, the top of the installation platform 2 is provided with an installation slot 221. The installation slot 221 is mainly used to install and fix the glass 50 and the cover plate 5. The front side of the fixed glass 50 can abut against the baffle. The baffle is equipped with a rubber strip. A pressure cap that abuts against the fixed glass 50 is installed on the installation slot 221, and a rubber strip is installed on the pressure cap. The cover plate 5 is installed on one side of the fixed glass 50. That is, the fixed glass 50 and the cover plate 5 are installed sequentially in the fixed area along the length direction of the side window. One end of the cover plate 5 can be snapped onto the baffle. In order to improve the overall strength and support of the cover plate 5, the installation slot 221 can be used to connect the bottom of the cover plate 5. It is preferable to provide two installation slots 221. The other installation slot 221 can be used to install a cover to maintain the flatness of the installation platform 2 and make it more aesthetically pleasing.

[0024] 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.
