Description

A SHUTTER FRAME FOR SECURING A PANEL AND A METHOD FOR

ASSEMBLING THE SAME

FIELD OF THE INVENTION

The present invention generally relates to a shutter frame for securing panels. More particularly, the present invention relates to a shutter frame for securing glass panels such that the fastening means are not visible and a method for assembling the same, for use in interior/exterior constructions purposes.

BACKGROUND

Shutter frames comprising various sheet materials or glass panels are employed in numerous situations, especially in the field of construction and more specifically for interior applications to give aesthetically pleasing appearance to spaces. For example, shutter frames are used in the fabrication of windows, interior/exterior wall cladding, curtain walling and partition walls, and doors, and more recently in kitchen cabinets.

Conventional frames which can accommodate the reception of single or double sheets of glass panel are widely known in the art.

Generally, glass shutter aluminium frame assembly comprises corner connectors for connecting frame, where the connection is performed using screws from behind the frame which are visible on the back side of frame assembly. Such assembling of frames destroys the aesthetics of the glass and the application at large. Screwing from behind the frames also leads to uneven surface finishes in such a way that two different materials are distinctly visible, thereby spoiling the aesthetics of the interior spaces.

U.S. Pat. No. 4,783,945 describes a furniture front element like a cabinet door, of which the frame leg members are joined in mitre cut and without any screwed connection. The lengths of the leg members are infinitely adjustable and the frame filling pieces are designed as a storage means in order to be able to change the front surface of the element to the desired extent. This patent however does not have a seamless finish, and the eccentric -joint fittings are visible from behind the frame. U.S. Pat. No. 4,987,713 describes a frame and strip assembly for mounting an edge portion of a panel The frame assembly process in this invention is done through welding or brazing and therefore welding/brazing marks are visible. Further the removable top frame portion is assembled using fasteners from sides, thereby making the screws visible on the sides of the frame.

U.S. Publication No. 20080042531 A1 provides cabinet structures and processes. Similarly, U.S. Pat. No. 4,248,022 discloses a shutter assembly including a frame to hold the interior panel formed of an expanded metal sheet. The frame assembly in these references are done from behind the frame members using fasteners which are visible behind the frame.

Elimination of uneven surface matching is a critical activity during production, Le., visibility of two or more different materials and uneven surface finish of the product leads to rejection by the customers due to aesthetic damage. Seamless product finish, maintaining smooth and good finish during frame production is very critical for interior applications where aesthetic of the final product is of utmost significance. Thus there is a need for providing flawless-seamless shutter frames for holding glass panels, without compromising on the structural strength and thickness of the frame and aesthetics to the frame/interiors. The present invention addresses the drawbacks associated in the production of conventional shutter frames.

OBJECT OF THE INVENTION

The object of the present invention is to provide a shutter frame for holding one or more panels, and also a method for assembling the same.

Another object of the present invention is to provide a shutter frame, such that the fastening means are not visible on any side of the frame, thereby providing good aesthetics to interiors of homes.

Yet another object of the present invention is to provide a support bar to assemble various kinds of accessories in the shutter frame, and also aid in providing structural strength to the shutter frame to take heavy load.
