Abstract
A pair of latch members 36R, 36L in a case 20C protrudes from an outer face of the case 20C by a spring 38 and when the case 20C is passed through a wall hole 22H, the latch members 36R, 36L are narrowed by an engagement between outer edge (guiding) slant face 36ROI, 36LOI and a wall hole 22H and after the case 20C has passed through the wall hole 22H, the latch members 36R, 36L are spread by a spring 38 so as to engage the engagement slant faces 36RLI, 36LLI with the wall hole 22H and also while fixing temporarily the case 22C to the wall 22 together with a flange 20FL of the case 22C. After that, a screw 32 is screwed to draw the nut 34 toward the flange 20FL and to engage securely the latch members 36R, 36L held to the nut 34 with the wall hole 22H to complete secure fixing of the case 20C.
Claims8
A wall through fixture device comprising a case with a flange of an object, the flange being engaged with an outer face of a wall, the case being passed through the wall and a wall inner face engagement means held by the case, the wall inner face engagement means being driven so as to engage with an inner face of the wall, thereby fixing securely the object to the wall with sandwiching the wall by the flange of the case and the wall inner face engagement means characterized in that the wall inner face engagement means comprises:
- a screw being rotatably supported to the case;
- a nut being held non-rotatably in the case and being allowed to move toward and away from a face of the wall;
- at least one latch member being formed separately from the nut and held displaceably to the nut in a direction along to a face of the wall and being engaged with an inner face of the wall and;
- a resilient member for urging the latch member apart from the nut;
- wherein the latch member is supported slidably by a protrusion formed on the nut while maintaining a posture such that the latch member is able to slide along a length of the protrusion in a direction along the face of the wall, the screw is screwed into the nut so as to make the nut and the latch member move toward the inner face of the wall, thereby sandwiching the wall between the flange of the case and the latch member.
