Description

SASH ASSEMBLY OF A SLIDING WINDOW TECHNICAL FIELD [0001] The present disclosure generally relates to windows, it particularly relates to sash for a door or window for mounting a glass panel. BACKGROUND [0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art. [0003] Sliding windows are commonly used in residential and commercial buildings for their aesthetic appeal and less consumption of space. The windows are typically configured to allow natural light and fresh air to enter the room while also providing insulation against heat. However, traditional sliding windows have a visible frame that can detract from the overall appearance of the window and can cause an unpleasant aesthetic appeal. [0004] To address this issue, sliding windows with concealed sash frame were developed. These windows have a sash frame that is concealed from view, giving the window a sleek and modern look. The sash frame or a part of the sash frame is hidden behind the glass, which results in giving a window a sleek look. [0005] While sliding windows with concealed sash frame have become increasingly popular, they present a unique set of challenges. One of the primary challenges with the existing sliding windows is ensuring that the window remains structurally integral. The sash carries the load of the glass and is subjected to repeated sliding movement, which may cause the sash to buckle and fail. This compromises not only the durability and longevity of the window but also poses safety risks to the occupants of the building. Therefore, it is important that sash is designed and engineered in a manner that the window is structurally sound and does not fail prematurely. [0006] KR102086754 discloses a concealed horizontal sliding window. The fixed window is attached on one side to the left outer frame or left frame member and on the other side to the middle outer frame or outer frame member (130). An adhesive material is used for attachment of securing glass pane with the frame. Such a configuration fails to address the inherent problem associated with the sliding windows which is the impact of forces due to the sliding movement of the windows on the sash. The existing solution will fail prematurely because of the inertial forces acting on the sash frame due to the operation of the sliding windows. [0007] Therefore, there is a need for an improved sliding window configuration that addresses the foresaid challenges and provides a reliable, durable, and structurally strong sliding window. SUMMARY OF THE DISCLOSURE [0008] In an embodiment, a sash assembly of a sliding window is disclosed. The sash assembly comprises a first glass panel and at least a pair of sashes. Each of the sashes is configured to receive the first glass panel and comprises a sash frame comprising an exterior surface and an interior surface, a first adhesive member engaged to the exterior surface of the sash frame, a first bonding agent and at least one first end support member. The first glass panel is mounted on the sash frame using the first adhesive member and the first bonding agent. The first end support member coupled to the sash frame and positioned adjacent to the first glass panel. The first glass panel is coupled to the sash in a manner that the first glass panel conceals at least a portion of the sash frame that is concealed behind the first glass panel. [0009] In an embodiment, a method of installing the sash assembly is disclosed. First step comprises, engaging the first adhesive member to the exterior surface of the sash frame. Second step comprises engaging the first glass panel with the first adhesive member. Third step comprises, applying the first bonding agent in a region between the first glass panel and the exterior surface of the sash frame to couple the first glass panel with the sash frame. Fourth step comprises, coupling the first end support member to the sash frame along the periphery of the sash frame. Final step involves applying a sealant between the edge of the first glass panel and the first end support member.
