(about the explanation of protrusion)
(about the explanation of variant part)
When reflector holding rack 2 (particularly back side maintaining part 2a) waits the lower low temperature of outside air temperature in the winter time, produced shrink when, local deformation portion 4 follows the thermal deformation of reflector holding rack 2 and produces distortion in the mode that can be stretched.Perhaps, when reflector holding rack 2 had produced het expansion when outside air temperatures such as summer are higher when, local deformation portion 4 produced distortion in the mode that can absorb this het expansion.Like this, produce distortion by variation and absorb and relax, follow the contraction of back side maintaining part 2a and the power (from the fastening force of circumference one side) that produces does not just act on catadioptre 1 according to outside air temperature.
That is, absorb and relax (inhibition), make catadioptre 1 not produce distortion such as strain because of the power that thermal deformation produces.
This local deformation portion 4 is formed integratedly with described protrusion 3 when reflector holding rack 2 is by moulding.In addition, shown in the enlarged drawing among Fig. 1, the thin wall shape of spill forms local deformation portion 4 by making the thickness of protrusion 3 for example.In addition, in the present embodiment, local deformation portion 4 is formed on the outstanding top of protrusion 3.
In addition, when the thickness of protrusion 3 is made thin wall shape, shown in the enlarged drawing among Fig. 1, both can make thin wall shape, also can make thin wall shape from the both sides of this thickness direction from thickness direction one side of protrusion 3.In addition, both can do the thin wall shape of grooving shape or muscle shape, can be not yet with protrusion 3 full week make thin wall shape, but in certain interval (scope), make thin wall shape.
In addition, be used for catadioptre 1 because of there is masterpiece in temperature traverse, be because thermal expansion coefficient (linear expansion coefficient) because of the two the different cause of material difference of the glass that forms catadioptre 1 and the resin that forms reflector holding rack 2 (back side maintaining part 2a).
Structure according to the reflector holding rack in the present embodiment that as above constitutes 2 like that, if reflector holding rack 2 produces and shrinks when waiting lower low temperature of outside air temperature in the winter time, the local deformation portion 4 on the outstanding top of protrusion 3 of then being set at is to being stretched by the shrinkage distortion direction shown in the arrow X in Fig. 4 (b), as the starting point of the distortion of following above-mentioned contraction and produce distortion.By this distortion, the outstanding shape of protrusion 3 changes, and (L1 → L2) expands to outstanding Width, thus, follows the contraction of reflector holding rack 2 and the power that acts on catadioptre 1 will be absorbed and relax.
Therefore, can be suppressed at the situation that produces distortion such as strain in the catadioptre 1, prevent that catadioptre 1 from damage etc. taking place.
In addition, when reflector holding rack 2 when produced het expansion summer, the expansion of the most significant back side maintaining part 2a of het expansion will be blocked by protrusion 3 that is formed and the local deformation portion 4 that is set on its outstanding top with roughly being U word shape or J word shape.That is, even back side maintaining part 2a produces het expansion, the local deformation portion 4 that follows the expansion of this thermal deformation also will be highlighted portion 3 and its outstanding top absorbs and blocking-up, can not feed through to the 2a of peripheral rim portion of the periphery 1a of (transmissions) maintenance catadioptre 1.Thus, can stably keep the periphery 1a of catadioptre 1, catadioptre 1 not produced rock.
In addition, by having made the structure that protrusion 3 with local deformation portion 4 is formed along the periphery of reflector holding rack 2, when in the periphery 1a with catadioptre 1 is embedded into the 2b of peripheral rim portion of reflector holding rack 2, assembling, can carry out in that protrusion 3 has been produced under the state of distortion.That is, be out of shape, for reflector holding rack 2, can more easily carry out the assembling operation of catadioptre 1 by the mode that protrusion 3 is turned back with the back side one side that is inverted to reflector holding rack 2.Therefore, can expect to enhance productivity and reduce production costs etc.
In addition, in the reflector holding rack of present embodiment, a plurality of projections 5 are arranged on install and keep on the back side maintaining part 2a of reflector holding rack 2 at the back side of catadioptre 1, the back side that keeps catadioptres 1 by these projections 5.By constituting in this wise, can eliminate the undesirable condition that the difference because of thermal expansion coefficient (linear expansion coefficient) produces, promptly eliminate because of the two the different undesirable conditions that produce of material of catadioptre 1 and reflector holding rack 2, keep catadioptre 1 under the state that rocks not producing with having good stability.
That is, make catadioptre 1 for the maintaining part 2a of the back side be not carry out in the mode of face contact bonding, but by by with back side maintaining part 2a between the point that forms of a plurality of projections 5 of devices spaced apart contact (put and support) and constructs and keeping catadioptre 1.With this structure, maintaining part 2a has produced under the situation of shrinking because of temperature traverse overleaf, and back side maintaining part 2a can be independent of catadioptre 1 and move individually to its thermal deformation direction.Therefore, catadioptre 1 is remained on the reflector holding rack 2 not producing under the state that rocks with having good stability.(other embodiments)
Fig. 5 is the horizontal cutaway view Amplified image of main portion of the another embodiment of the expression reflector holding rack relevant with the present invention.
In addition, compare with above-mentioned embodiment, the outstanding mode difference of the above-mentioned protrusion 3 in this embodiment in addition, is that above-mentioned local deformation portion 4 is arranged on a plurality of positions, and this aspect also is different.On structure division in addition, because the embodiment with above-mentioned is identical basically, so, thus the explanation that repeats is omitted to identical structure division additional phase symbol together.
As shown in Figure 5, compare with above-mentioned embodiment, the standing shape of protrusion 3 be formed dark (higher).And, on the outstanding top and these two positions of outstanding base portion of protrusion 3, formed the local deformation portion 4,4 of thin wall shape.
Structure according to the reflector holding rack in the present embodiment that as above constitutes, if reflector holding rack 2 produces and shrinks when waiting lower low temperature of outside air temperature in the winter time, the outstanding top and the local deformation portion on these two positions of outstanding base portion 4 that then are set at protrusion 3 just produce distortion, to being stretched with the shrinkage direction shown in the arrow X in Fig. 5 (b).By this distortion, the outstanding shape of protrusion 3 changes, and (L1 → L2) expands to outstanding Width, thus, follows the contraction of reflector holding rack 2 and the power that acts on catadioptre 1 will be absorbed and relax.In addition, even produced at reflector holding rack 2 under the situation of het expansion, by the distortion of local deformation portion 4, the power that acts on catadioptre 1 also can be absorbed and relax.
In addition, the concrete structure in the embodiment of the present invention is to be not limited to above-mentioned embodiment, though in the scope that does not break away from the main idea of the present invention described in each technical scheme, have design modification etc. also be involved in the present invention.
For example, in the above-described embodiment, though protrusion 3 has been made above-mentioned roughly J word shape or U word shape,, in addition also can make it form roughly V word shape or rectangular shape highlightedly.In addition, 4 ones in local deformation portion can not formed thin wall shape yet, but form the polyline shaped of the degree that can not reduce the maintenance rigidity (durability) that catadioptre 1 is kept by the 2b of peripheral rim portion.
In addition, local deformation portion 4 is not limited to outstanding top and these two positions of outstanding base portion of protrusion 3, but also can be set at protrusion 3 is produced on the position of elastic deformation, make when reflector holding rack 2 has produced contraction, to absorb and relax the power of following this thermal deformation effectively.That is, also local deformation portion 4 can be arranged on the position that when having produced thermal deformation, in protrusion 3, is easy to generate stress concentration.In addition, the position quantity that local deformation portion 4 is set also can be that 3 or 4 etc. are a plurality of.
