Device for securing an apparatus in a wall

Claim 1

A device for securing a substantially rigid housing containing an apparatus in a receiving wall having inner and outer sides, the housing having a pair of mounting surfaces facing away from each other in opposite directions, the mounting surfaces being spaced a certain distance apart from each other, the device comprising: (a) a mounting frame of elastically deformable material, said frame including a frame wall element, said frame defining an internal area therewithin; (b) said frame including an abutment shoulder for engagement with the outer side of the receiving wall; (c) said frame including first and second locking tongues projecting from said frame wall element in opposite directions with respect to said frame wall element, said tongues being elastically movable toward each other and toward said frame wall element; (d) said first locking tongue extending outwardly with respect to said internal area and being adapted for engagement with the inner side of the receiving wall, said second locking tongue extending inwardly with respect to said internal area and having a locking surface disposed generally parallel to the receiving wall and adapted for face-to-face, locking engagement with one mounting surface of the housing containing the apparatus; (e) said frame including a partial wall element extending approximately parallel to the receiving wall when the device is installed, said partial wall element providing an abutment surface disposed in opposed, parallel relationship with the locking surface of the second locking tongue and facing toward the locking tongue, said abutment surface being adapted for engagement with the other mounting surface of the housing of the apparatus, said abutment surface and said locking surface being spaced approximately the same distance apart as the mounting surfaces of the housing of the apparatus to lock the housing between said abutment surface and said locking surface.

Claim 2

A device for securing a substantially rigid housing containing an apparatus in a receiving wall having inner and outer sides, the housing having a pair of mounting surfaces facing away from each other in opposite directions, the mounting surfaces being spaced a certain distance apart from each other, the device comprising: (a) a mounting frame of elastically deformable material, said frame including a frame wall element, said frame defining an internal area therewithin; (b) said frame including an abutment shoulder for engagement with the outer side of the receiving wall; (c) said frame including first and second locking tongues projecting from said frame wall element in opposite directions with respect to said frame wall element, said tongues being elastically movable toward each other and toward said frame wall element; (d) said first locking tongue extending outwardly with respect to said internal area and being adapted for engagement with the inner side of the receiving wall, said second locking tongue extending inwardly with respect to said internal area and having a locking surface disposed generally parallel to the receiving wall and adapted for face-to-face, locking engagement with one mounting surface of the housing containing the apparatus; (e) said frame including a partial wall element extending approximately parallel to the receiving wall when the device is installed, said partial wall element providing an abutment surface disposed in opposed, parallel relationship with the locking surface of the second locking tongue and facing toward the locking tongue, said abutment surface being adapted for engagement with the other mounting surface of the housing of the apparatus, said abutment surface and said locking surface being spaced approximately the same distance apart as the mounting surfaces of the housing of the apparatus to lock the housing between said abutment surface and said locking surface.
