摘要:
Door for a refrigerated cabinet, wherein the door is double-walled with two transparent walls (2). The two transparent (2) are produced from flat plastic panels. The door (1) comprises one or more inserts (3, 4) which are positioned on the circumference of the two transparent walls (2) and hold the two transparent walls (2) parallel to one another at a predefined distance (d) from one another. The door (1) is designed in such a way that an optimum view without distortion is provided of the products behind the door (1). The door (1) is insulating and condensation-free.
摘要:
The present invention is directed to a door facing formed from a polymeric composite material. The door facing has a first major surface intended to be interiorly disposed and a second major surface intended to be exteriorly disposed. At least a portion of the first major surface is to be subjected to thermal and mechanical stresses during door assembly. The first major surface has a textured pattern in the portion to be subjected to thermal and mechanical stresses. The textured pattern includes a plurality of spaced grooves extending into the first major surface and minimizing thermal and mechanical stresses. A door formed with the disclosed polymeric door facing and a method of forming a door facing are also disclosed.
摘要:
The present invention relates to a moulded plastics door (1) comprising first (2) and second (4) opposing panels separated by a spacer, wherein the panels and the spacer together define a void adapted to be filled with an insulating material (16) and characterised in that the spacer is integral with at least one of the panels.
摘要:
An improved closure member construction such as a door (100) comprises internal closure door components (102, 104, 106) and an outer covering (110) encapsulating the internal door components (102, 104, 106). The outer covering comprises a sheet or sheets (110) of a plastics material formed about the door (100) and welded in position about the door by a weld (114) so as not to leave any overlapping edges, crevices or gaps. The weld (114) is provided between adjacent or contiguous edges of the sheets (110).
摘要:
The present invention provides a bi-active method of mounting a monolithic polycarbonate sheet or a laminate in a semi -rigid metallic framing system along two parallel sides of a rectangular shaped sheet or laminate with the two shorter parallel sides being unconstrained. In the case of a square shaped sheet, two parallel sides are supported in the semi -rigid frame, and the other two parallel sides are unconstrained. The semi-rigid frame utilizes cylindrically shaped hardware (i.e., bolts, rivets, studs, etc.) to hold the sheet or laminate. The semi-rigid frame is designed, via section and material properties, to flex and hinge about fixed mounting points along the length of the frame.
摘要:
Compression molded pigmented door skins fabricated by compression molding a pigmented, curable, unsaturated polyester sheet molding compound containing a co-curable unsaturated monomer, a low profile additive, and a microvoid-reducing thermoplastic polymer, exhibit uniform stainability while maintaining a low linear thermal coefficient of expansion. Such door skins are suitable for preparing wood grain textured exterior insulated doors which exhibit minimal thermal deflection when exposed to interior/exterior temperature differentials, even at eight foot door heights. The doors may be stained without first applying a seal coat.
摘要:
A method is provided for making an annealed door skin or composite door assembly. At least the door skin is formed of a composition comprising a thermoset binder and fiberglass. The door skin, alone or in combination with other parts of a door assembly, is subjected to annealing to make the annealed door skin. The process of annealing comprises the step of heating the door skin, alone or in combination with other parts of the door assembly, above the glass transition temperature yet below the thermal degradation temperature of the thermoset binder for a sufficient amount of time to cause release internal stresses in the door skin, then the step of cooling the door skin.
摘要:
A door panel for use with an open sided container (21) comprising a plastic door panel (11) and a plurality of inserts (26) located within the panels that enable attachment of fittings such as hinges (13) and latches (14) to the panel (11). The panels (11) can be used in pairs to form bi-fold doors. The door panels (11) provide secure closure for the open sided containers with advantage of significant weight saving.
摘要:
A panel for furniture and entrance doors and panels, with at least one surface decorated with bevel or rounded longitudinal sections extending along three or four sides and possibly with elevated or depressed central plates or ridges or grooves that may extend in any direction, longitudinal, transverse or at any angle to the longitudinal or transverse axes of the panel, the said panel finished in plastic laminate such as HPL, CPL or Formica. The plastic laminate is post formed by bending under heat and the occurrence of breaks at transverse bending lines is prevented by placing the basal panel in a template and placing over the basal panel a sheet of plastic laminate that is slightly larger than the basal panel such that the edges of the plastic laminate are supported by the walls of the template during post forming along the edges of the panel. The excess material is then cut off and a smooth continuous plastic laminate finish is obtained. Where elevated or depressed plates or ridges or grooves result in a hollow space between the plastic laminate and the basal plate into which the plastic laminates is to be forced, a rubber sheet of appropriate size and sufficient thickness is placed above the plastic laminate whereby the plastic laminate is protected from breaking under the pressure exerted to post form the said plastic laminate.
摘要:
A door member (10) comprising a frame (14) having a first side and a second side, opposite the first side, a core (12) positioned within the frame (14), and a molded skin (24) attached to the first side of the frame (14). The skin (24) is prepared from a molding compound which, when molded, has a shrinkage of between about -0.0003 to about +0.0015. The molding compound comprises a resin system comprising a curable polyester resin, a co-curable unsaturated monomer, and at least two low profile additives. The molding compound also comprises at least about 30 percent by weight, based on the weight of the molding compound, of filler material, and fibrous reinforcement in an amount of less than about 35 weight percent, based on the weight of the molding compound.
