[structure of mounting structure 7]
In the inner face 22A side of the lower house 22 corresponding, be provided with and be used for projector 1 is installed on the mounting structure 7 of ceiling 91 grades of buildings with above-mentioned hole 2E9 of portion and lug boss 2E10.
This mounting structure 7 is as Figure 6 and Figure 7, and its structure possesses as the embedded nut 71 of installing component and pad 72.
Embedded nut 71 adopts metal to wait and forms, and at this embedded nut 71, forms cylindrical portion 711 and flange part 712, and this flange part is formed at a side's of this cylindrical portion 711 end side.
Wherein, cylindrical portion 711 is equivalent to cylindrical portion of the present invention, and the internal diameter size of the outside dimension of this cylindrical portion 711 and the 2E9 of hole portion is roughly the same, this cylindrical portion 711 from this cylindrical portion 711, with formed the end of flange part 712 1 side opposition sides, from the inner face 22A side hot pressing hand-hole 2E9 of portion of lower house 22.And this cylindrical portion 711 touches at the formed stage portion 2E91 of the 2E9 of hole portion to the end of the direction of insertion front of the 2E9 of hole portion, prevents that projector 1 from being that embedded nut 71 comes off from the 2E9 of hole portion when hanging posture.
Form threaded hole 7111 in the inside of this cylindrical portion 711, this threaded hole is embedded nut 71 open-ended to the direction of insertion front of the 2E9 of hole portion.To this threaded hole 7111, be threadedly engaged with the bolt 92 that is arranged at behind top board 91, the 2E9 of inserting hole portion.
In addition, in the periphery of cylindrical portion 711, form 2 outstanding ring-shaped protrusions 7112 of direction outside face.When this ring-shaped protrusion 7112 has been pressed into the 2E9 of hole portion in cylindrical portion 711, embed the inner face of the 2E9 of this hole portion, prevent that cylindrical portion 711 from coming off from the 2E9 of hole portion.Therefore, to the 1st sidepiece 2E11 of the lug boss 2E10 that forms the hole 2E9 of portion, by cylindrical portion 711 constantly by the direction stress applications of expansion laterally.
In addition, the outside dimension of pad 72 has the stiffening rib 2E13 size of the whole degree that covers roughly that will constitute lug boss 2E10 when being disposed at stiffening rib 22A1 inboard.Therefore, this pad 72 touches the flange part 712 in embedded nut 71, utilizes this flange part 712, is pressed in the stiffening rib 2E13 that constitutes lug boss 2E10.
When the projector 1 that will have this mounting structure 7 is installed on ceiling 91, between the lug boss 2E10 of the flange part 712 of embedded nut 71 and lower house 22, installing under the state of pad 72, the lug boss 2E10 front end of the lower surface 2E side of lower house 22 is touched in ceiling 91, in by the formed hole 2E9 of portion of the 1st sidepiece 2E11 of this lug boss 2E10, be inserted in the set bolt 92 of ceiling 91.After this, the threaded hole 7111 of embedded nut 71 set in the 2E9 of hole portion and the bolt 92 behind the 2E9 of patchhole portion are threadedly engaged with, fix these embedded nuts 71 and bolt 92.
At this moment, though the load of projector 1 is transmitted to the flange part 712 of embedded nut 71 by pad 72 from lower house 22, but because at the inner face of cylindrical portion 711 formed ring-shaped protrusion 7112 2E9 of embedded hole portion of this embedded nut 71, and the front end of cylindrical portion 711 touches the stage portion 2E91 in the 2E9 of hole portion, comes off from the 2E9 of hole portion so can prevent embedded nut 71.Moreover because flange part 712 supports the load of the projector 1 that applies by pad 72, thereby projector 1 is supported to be fixed in ceiling 91.
According to the as above projector 1 of present embodiment, can produce following effect.
That is to say, since form the following hole 2E9 of portion lug boss 2E10 the 1st sidepiece 2E11 and be formed at the 1st sidepiece 2E11 the 2nd sidepiece 2E12 on every side and be connected by a plurality of stiffening rib 2E13, in this hole portion embedded nut 71 is set, even thereby be full of cracks etc. takes place, the 1st sidepiece 2E11 is expanded laterally at the 1st sidepiece 2E11, also can utilize the 2nd sidepiece 2E12 and stiffening rib 2E13, suppress the distortion of the 1st sidepiece 2E11.In view of the above, even if occur when damaged at the 1st sidepiece 2E11, also since can be in the inboard of the 1st sidepiece 2E11 the 2E9 of hole portion internal fixation embedded nut 71 just, thereby can utilize the load of these embedded nut 71 support projection machines 1.
Here, if adhere on embedded nut 71 under the previous status of grease etc. this embedded nut 71 is pressed in the 2E9 of hole portion, then this grease permeates in the 1st sidepiece 2E11 sometimes, produces the chemical stress cracking.In this case, sometimes with the 1st approaching sidepiece 2E11 of embedded nut 71 in chap.And if this be full of cracks development to some extent, then crackle appears in the 1st sidepiece 2E11 sometimes, consider the possibility that embedded nut 71 comes off from the 2E9 of hole portion.At this possibility, even because when be full of cracks had taken place the 1st sidepiece 2E11, the distortion of the 1st sidepiece 2E11 also was inhibited by the 2nd sidepiece 2E12 and stiffening rib 2E13, thereby can suppress embedded nut 71 coming off from the 2E9 of hole portion.Thereby, because the body 2 that frames up outside these embedded nut 71 reliable supports, thereby can prevent projector 1 falling with simple structure from ceiling 91.
In addition, the 1st sidepiece 2E11 of lug boss 2E10 is connected by stiffening rib 2E13 with the 2nd sidepiece 2E12.That is to say, between the 1st sidepiece 2E11 and the 2nd sidepiece 2E12, form the space.In view of the above,, also can suppress this be full of cracks and develop, can suppress the distortion of the 1st sidepiece 2E11 always by the 2nd sidepiece 2E12 and stiffening rib 2E13 to the 2nd sidepiece 2E12 even when be full of cracks has as above taken place the 1st sidepiece 2E11.Thereby, even when be full of cracks takes place the 1st sidepiece 2E11, also can reliably suppress the distortion of the 1st sidepiece 2E11, even if the long-term whereby suspension posture that keeps also can prevent falling of projector 1.
In addition, the 2nd sidepiece 2E12 make the 2nd sidepiece 2E12, from the projected direction front end of lower surface 2E near the 1st sidepiece 2E11 be obliquely installed, and lug boss 2E10 forms the conical shaped shape on the whole.In view of the above, form situation roughly cylindraceous with lug boss 2E10 and compare, can form the short part of size at stiffening rib 2E13.That is to say, can make the distance between the 1st sidepiece 2E11 and the 2nd sidepiece 2E12 approaching.Thereby, when breakage appears in the 1st sidepiece 2E11, can increase the resistance that stops the 1st sidepiece 2E11 expansion laterally, therefore can further reliably suppress the distortion of the 1st sidepiece 2E11.
Moreover, because lug boss 2E10 forms the conical shaped shape, thereby compares with the situation of the pyramid shape that forms pyrometric cone shape and quadrangle cone shape etc., can form lug boss 2E10 easily, the molding in the time of can carrying out lower house 22 shapings easily.Thereby, the formation of lower house 22 is oversimplified.
In addition, lug boss 2E10 forms, and the lower surface 2E of the body 2 outside surface sides that frame up outside conduct is outstanding.In view of the above, the stiffening rib 2E13 that the 1st sidepiece 2E11 that constitutes this lug boss 2E10 and the 2nd sidepiece 2E12 are connected exposes to the inner face 22A of lower house 22 side.Therefore, lower surface 2E concavo-convex of lower house 22 can be reduced, and because the inner face 22A side after forming locator protrusions etc. forms stiffening rib 2E13, thereby the molding of this lower house 22 when being shaped can be carried out more simply.Thereby, can further carry out the formation of lower house 22 easily.
In addition, at embedded nut 71,, and utilize this flange part 712 by the flange part 712 of formation with the inner face 22A subtend of lower house 22, when being the suspension posture, projector 1, therefore can reliably prevent falling of projector 1 by the load of flange part 712 support projection machines 1.
In addition, between the lug boss 2E10 of the flange part 712 of embedded nut 71 and lower house 22, pad 72 is installed.The outside dimension of this pad 72 forms greatlyyer than the outside dimension of flange part 712.In view of the above, can enlarge the scope of the flange part 712 of embedded nut 71 by pad 72 joints.Thereby, can prevent more reliably that embedded nut 71 from from the coming off of the 2E9 of hole portion of lower house 22, therefore can further reliably prevent falling of projector 1.
In addition, because pad 72 is installed between flange part 712 and lug boss 2E10, thereby the operation that is pressed into of embedded nut 71 is improved.
