Definitions

  • ABSTRACT [30] Foreign Application Priority pm
  • One side edge of a door is bent into L-shaped configuration to oppose the inwardly bent portion of the peripheral flange of 21 1969 Japan "44/65640 housing.
  • the free end of a resilient anchor plate is shaped into a C-shaped configuration to be received in the L-shaped side [52] US. Cl.
  • This invention relates to a housing or casing with a door and more particularly to an improved door mounting mechanism.
  • the mechanism for mounting a door on a housing or casing takes the form of a hinge about which the door is rotated.
  • the shaft of the hinge is located on the outside of the housing it is easy to remove the shaft and hence the door which is undesirable from the standpoint of crime.
  • the exposed hinge greatly impairs the appearance of the housing.
  • a door mounting mechanism comprising a housing with its peripheral flange bent inwardly to form an opening, a door disposed in the opening, one side edge of the door being bent inwardly into substantially L-shaped configuration to oppose the inwardly bent portion of the peripheral flange, and a resilient anchor plate with one end secured to the inner wall of the housing, the free end of the anchor plate being shaped into generally C- shaped configuration to be received in an interlocking relationship in the L-shaped side edge to resiliently clamp the side edge between the free end and the inwardly bent portion of the peripheral flange.
  • FIG. 1 shows a perspective view, partly in section, of a housing embodying this invention and FIGS. 2a, 2b and 2c are partial sectional views in reversed position of the housing shown in FIG. 1 to show successive steps of opening and closing the door.
  • a housing is provided with a front door 12.
  • the mechanism or hinge for mounting the door on the housing is completely concealed in the housing thus improving the appearance.
  • the hinge cannot be reached for the purpose of destroying the door mounting mechanism.
  • the housing 10 is representative of any type of door frame in which a door with a hinge of the type described can be mounted.
  • the inner ends of the peripheral flanges l4 and 16 of the housing which define a door opening extend inwardly to form flat sides 14a: and 16a and their extreme ends 14b and 1612 are bent at right angles to oppose each other.
  • Opposite sides 12a and 12b of the door 12 are bent at approximately right angles to engage inwardly extending flat sides 14a and 160 respectively.
  • the inner end of side 12b abuts against bent portion 16b and may be relieved to clear 16a upon opening as shown.
  • Suitable locking means is used to lock the door in its closed position but since such locking means is well known and forms no part of this invention it is not shown in the drawing.
  • An anchor plate 20 of a suitable resilient metal is secured at its one end to the inner wall of the housing, the outer end 20a of the anchor plate being shaped into a letter C configuration.
  • the first part 12a of the L-shaped member is resiliently clamped between the C-shaped free end 20a and the inwardly extending flat side 14a of the peripheral flange 14 by the biasing force of the anchor plate 20 normally acting in the direction of A.
  • the bent end 14b of the inwardly extending flat side portion 14a acts as a stop to hold the door in its opened condition which is held by the clamping force exerted between the C- shaped free end 20a and inwardly extending flat side 14a.
  • the operation is reversed.
  • the door does not move laterally beyond its original position against flat side 14:: and its extent, when opened, beyond the face I4 of the door frame is diminished an amount equal to the width of the flat side 14a.
  • the construction permits the door to be fully opened in a space less than that required of other hinge constructions.
  • the door mounting mechanism of this invention is completely concealed in the housing thus not only providing a neat appearance but also discouraging crime. Moreover, the anchor plate can be worked independently of the housing without requiring precise working and can be attached with machine screws 18.
  • Means mounting a door on a housing in which said housing has an end wall and a front wall, said front wall having an opening therethrough and a flange extending inwardly along one side of said opening and parallel to said end wall, a door disposed in said opening, one side edge of said door extending inwardly to form a flat side at right angles to the face of said door and being parallel to said front wall flange, the inner edge of said flat side having a reversely turned flange that is parallel to said door face and at right angles to said front wall flange; and a resilient anchor plate, one end of said anchor plate being secured to the said end wall of said housing and the free end of said anchor plate being formed into a generally C-shaped portion having a first part engaging the interior face of said door,
  • a door hinge connecting a door to a housing comprising a fixed side wall having an inner flat side at right angle to the face of the door; an L-shaped member extending away from the face of the door at its edge with the first part of said member abutting said flat side and the second part of said member extending away from said flat side, said L-shaped member and the adjacent part of said door forming a comer; a resilient anchor plate having one end secured to the side wall remote from said flat side and having its other end generally in the form of a C portion fitting within the corner formed by said flat side as opening progresses whereby lateral movement of the door beyond its closed position in the direction away from said anchor plate is precluded and whereby the dimension of the door, when opened, beyond said housing is less than the width of the door when closed.
