Description

Technical Field

[0001] This utility model relates to the field of concealed sash window and door systems, and in particular to a side thermal insulation strip for a concealed sash window and door system. Background Technology

[0002] The core feature of concealed sash window and door systems is that the sash profiles are constructed only on the inside of the glass, with thermal break strips replacing the sash profiles on the outside of the glass. This makes the sash profiles appear to be completely hidden from the glass frame, making them almost invisible. The edge of the glass presents a rectangular, linear, slender outline, thus creating a minimalist and elegant design effect.

[0003] However, because window glass is exposed to wind and sun for a long time, it is easily damaged by external forces, and the thermal insulation strip itself and the adhesive applied to the edge of the glass to bond the thermal insulation strip will show obvious aging problems.

[0004] Furthermore, traditional concealed sash window and door systems typically employ a double-cavity thermal break strip to create a thermal insulation shielding cavity for the sash profile. Therefore, once the thermal break strip ages, becomes damaged, or falls off, it incurs significant replacement and maintenance costs. Additionally, the molds used to develop this special thermal break strip structure are expensive, making it difficult to meet market demands. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a side thermal insulation strip for a concealed sash window system. The aging rate of the side thermal insulation strip is slowed down by using a head clip, and the double-cavity thermal insulation strip is replaced by a clip design to reduce maintenance costs and mold costs, thereby achieving a longer service life and lower production costs.

[0006] To solve the above-mentioned technical problems, the present invention provides a sash-side thermal insulation strip for a concealed sash window system, comprising a thermal insulation strip body, a head clip, and a latch. The thermal insulation strip body has an outer surface for sealing the glass and an inner surface for engaging with a frame-side sealing strip. The thermal insulation strip body also has an outer end for engaging with the frame-side sealing strip and an inner end face for engaging with the window sash profile. An integrally formed head clip is vertically arranged at the outer end. A pair of hooks are provided on the inner surface. The inner wall of the hooks surrounds and forms the latch. The outer wall of the hooks is provided with a sealing surface for interference fit of the frame-side sealing strip.

[0007] In a preferred embodiment of this utility model, an integrally formed tail head is vertically disposed on the same side of the head head, the head head and the tail head form a C-shaped glass encapsulation groove, and the inner end face is provided with a through-strip pin, the through-strip pin being a wide-body shape covering the entire tail head.

[0008] In a preferred embodiment of this utility model, the sealing contact surface of the outer wall of the hook is inclined to the slot side.

[0009] In a preferred embodiment of the present invention, the outer surface of the head clip is covered with an n-shaped alloy sheath, and both the alloy sheath and the head clip are opaque.

[0010] In a preferred embodiment of this utility model, the bayonet opening is filled with a fan-side sealing strip.

[0011] The beneficial effects of this utility model are: the concealed sash window and door system provided by this utility model has a side thermal insulation strip that slows down the aging rate of the side thermal insulation strip by using a head clip, and replaces the double-cavity thermal insulation strip with a clip design to reduce maintenance costs and mold costs, thereby achieving a longer service life and lower production costs.

[0014] Figure 2 This is a structural diagram of the inner end face of a wide-body structure. Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1-2 As shown, the embodiments of this utility model include:

[0017] A concealed sash window system includes a sash-side thermal insulation strip, comprising a thermal insulation strip body 1, a head clip 2, and a latch 3. The thermal insulation strip body 1 has an outer surface 1a for encapsulating glass 100 and an inner surface 1b for engaging with a frame-side sealing strip 200. The thermal insulation strip body 1 also has an outer end 1c for engaging with the frame-side sealing strip 200 and an inner end face 1d for engaging with the window sash profile 300. The outer end 1c is vertically provided with an integrally formed head clip 2. The inner surface 1b is provided with a pair of hooks 3ab. The inner wall of the hooks 3ab surrounds to form the latch 3. The outer wall of the hooks 3ab is provided with a sealing surface 3c for interference fit of the frame-side sealing strip 200.

[0018] The inner end face 1d is vertically provided with an integrally formed tail head 4 on the same side as the head head 2. The head head 2 and the tail head 4 form a C-shaped glass encapsulation groove cc. The inner end face 1d is provided with a through-strip pin 1dc. The through-strip pin 1dc is wide and covers the entire tail head 4.

[0019] Furthermore, the sealing surface 3c of the outer wall of the hook 3ab is inclined toward the bayonet 3 side.

[0020] Furthermore, the outer surface of the head clip 2 is covered with an n-shaped alloy sheath 5, and both the alloy sheath 5 and the head clip 2 are opaque.

[0021] Furthermore, the bayonet 3 is filled with a sector-side sealing strip.

[0022] The concealed sash window system uses a side thermal break strip instead of the outer part of the ordinary sash profile 300. Its outer surface 1a is coated with adhesive and directly sealed to the edge of the double-glazed glass 100. Because sunlight can directly reach the side thermal break strip, it is prone to aging. At the same time, acidic pollutants in the air can also corrode the adhesive layer on the outer surface 1a used to seal the double-glazed glass 100, making the side thermal break strip prone to detachment and peeling.

[0023] To address the issue of aging and detachment of the fan-side thermal insulation strip, a head clip 2 was designed. The head clip 2 can completely block direct sunlight, thereby extending the service life of the fan-side thermal insulation strip.

[0024] To further protect the head clip 2 from external damage, an alloy sheath 5 is applied to the exposed portion of the head clip 2, thereby extending its service life.

[0025] In order to achieve the same thermal insulation effect as the double-cavity thermal insulation strip, the snap-fit ​​3 structure is adopted to replace the double-cavity thermal insulation strip commonly used in the existing technology. When the window sash and window frame are closed, the frame side sealing strip 200 can be interference-fitted at the snap-fit ​​3 to surround the snap-fit ​​3 and form a thermal insulation cavity.

[0026] Because the fan-side heat insulation strip of the bayonet type 3 is easy to press, the development cost of its mold is relatively low. Therefore, it can greatly reduce the production cost of the part, increase the production capacity of the part, thereby meeting market demand and reducing maintenance costs.

[0027] Because the inner end face 1d is farther from the head clip 2, the fan-side heat insulation strip and its surrounding adhesive layer at the inner end face 1d are affected by light refraction, and their aging rate is faster than that of the adhesive layer closer to the head clip 2. This causes cracks in the adhesive layer to form from the inner end face 1d. To further improve the service life of the fan-side heat insulation strip, a wide-body design was specifically made at its connection with the fan profile 300, i.e., the inner end face 1d. This improves the structural rigidity of the inner end face 1d and provides a larger bonding area between the glass 100 and the fan-side heat insulation strip.

[0028] In summary, this utility model provides a side thermal insulation strip for a concealed sash door and window system. The head clip 2 slows down the aging rate of the side thermal insulation strip, and the design of the clip 3 replaces the double-cavity thermal insulation strip to reduce maintenance costs and mold costs, thereby achieving a longer service life and lower production costs.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
