Abstract: A door comprises a main frame with an opening, a front window frame and a rear window frame. The main frame includes a connection mold formed along an inner circumference of the opening and formed with a plurality of projections and recessed hooking channels. A glass is disposed in the opening and fixed by the front window frame and the rear window frame. The front window frame includes catching protrusions to be fitted into the recessed hooking channels, a support end to support the glass, and hooks protruding rearward and resiliently hooked to a rear side of the projections. The rear window frame includes catching protrusion to be fitted into the other recessed hooking channels, a support end to support the glass, and hooks protruding frontward and resiliently hooked to a front side of the projections.

Abstract: Disclosed is a door exhibit case for either exhibiting or displaying doors. The door comprises a frame body, a plurality of guide rails, and a plurality of rotary units. The frame body has a door receiving space capable of receiving a plurality of doors within the interior thereof, wherein the received doors are capable of being extracted through at least one of front and rear sides of the frame body. The guide rails are formed on the inner top surface of the frame body and extend in the front-to-rear direction. Each sliding bar is supported by one guide rail so as to be extracted to the outside of the frame body through the front or rear side of the frame body. Each rotary unit has opposite ends, one end being connected to the bottom surface of a corresponding sliding bar and the other end being connected to the top surface of a corresponding door.

Abstract: The present invention relates to a door.

Abstract: The present invention relates to a door capable of preventing the door from being warped or bent and also from being damaged due to the penetration of moisture. The door of the present invention comprises front and rear panels which define front and rear surfaces of the door, respectively; a pair of horizontal frames which are fixed to upper and lower ends of the front and rear panels between the front and rear panels, respectively; and a pair of vertical frames which are fixed to right and left ends of the front and rear panels between the front and rear panels, respectively. Each of the vertical frames includes an inner frame which is fixed to an innermost position and made of wood, a middle frame which is fixed to an outer side of the inner frame and made of metal, and an outer frame which is fixed to an outer side of the middle frame and made of a synthetic resin. Further, a foaming agent is filled in an inner space formed between the front and rear panels by the frames to form a foam layer.

Abstract: The present invention relates to a door that has a sufficient strength against bending and is not damaged by moisture. Front and rear plates 10 and 20 of the door of the present invention are made of a glass fiber material. A pair of transverse frames 30a and 30b made of synthetic resin and the a pair of longitudinal frames 40a and 40b made of lumber comprising bonded sheets of veneer are fixed to edge portions of the front and rear plates therebetween. Upper and lower frames of the longitudinal frames are fixedly bonded to bottom and top surfaces of the respective transverse frames so that they cannot be exposed to the outside. Further, a pair of covers 50 made of synthetic resin are attached to outer side surfaces of the longitudinal frames so that the longitudinal frames cannot be exposed to the outside. An inner space defined by the frames between the front and rear plates is filled with a foaming liquid to form a foam layer.

Abstract: The present invention provides an adhesive composition comprising a main adhesive composed of 50 to 100% by weight of BPA epoxy resin, 0.5 to 5% by weight of a dispersant and 0.5 to 5% by weight of a fluidity adjusting agent as additives, and 0 to 50% by weight of a filler; and a curing agent composed of 15 to 50% by weight of polymeric amine, 1 to 99% by weight of amine-terminated reactive rubber and 0.5 to 5% by weight of an anti-settling agent as additives, 0.1 to 10% by weight of tertiary amine as a catalyst, and 0 to 60% by weight of a filler. The main adhesive component and the curing agent component are mixed in a ratio of 1:2 to 2:1 by weight. The adhesive comprising the adhesive composition of the present invention has superior adhesive force and peeling strength and thus exhibits very excellent adhesiveness in bonding an SMC board to PVC material or wood.

Abstract: Disclosed herein is a water-soluble alkyd composition, which comprises an ester reactant consisting of a dehydrated fatty acid (DCOFA), trimethylolpropane (TMP), isophthalic acid (IP acid), trimellitic anhydride (TMA) and butyl cellosolve; a mixture of acrylic monomers including methyl methacrylate (MMA), n-butyl methacrylate (n-BMA), butyl acrylate monomer (BAM), styrene monomer (SM) and acrylic acid (AA); and 3˜4% by weight of triethylamine (TEA) as a pH-adjusting agent. The weight ratio of the mixture of acrylic monomers to the ester reactant is in the range of 1:0.8˜1:1. Paint produced using the alky resin composition is also disclosed. The paint exhibits improved workability and adhesiveness, particularly, excellent paintability when being applied on SMC (sheet molding compound) materials.

Abstract: A door sill-to-jamb kit manufactured from rot-resistant thermoplastic material is placed between a bottom of a side jamb and a sill of a door frame assembly. Parallel tenons fitting into mortises at the base of the side jamb and fasteners secure the door sill-to-jamb kit to the side jamb as well as to the door sill. Elevated height of the side jamb prevents contact with moisture on the surface of door sill and between the door sill-to-jamb kit and the door sill, thus reducing a risk of rotting of the wooden side jamb.
