On the one hand,, canopy eaves 26 as interior dress plate forwards is installed highlightedly, and below each screen work 11, fluorescent lamp 27...... is housed respectively in that inboard, the internal layer discharge opening of canopy eaves 26 are inboard along whole width at the front end of thermal wall 2 roof 2A.On the other hand, at the whole width of the antetheca 2B upper end edge of the side cut of thermal wall 2 peristomes 21 lower edges horizontal bar 28 is installed, the leading section 28A below these horizontal bar 28 outsides forms the shape that the bottom cuts.
31,32 for being installed in the decorative panel up and down on the antetheca 2B front, and 33 is cushion pad, and in addition, side plate 3 has the width of regulation, is inlaying combining glass 29 on the middle body of its front.
On in the face of the canopy eaves 26 of clearance G and outer dress plate 36, also post suitable cushion pad, adorn outside plate about hold mounting cover 38, holding portion 37 is sealed.
In the holding portion 37 on above-mentioned canopy eaves 26, the installing plate made from wide hard resin with canopy eaves 26 41 erectly is set, the front 42 of installing plate 41 is the top 42A stairstepping more forward than bottom 42B, and the upper-lower position in these fronts forms relative joint fastener 43,43 and 44,44 respectively.
Like this, night cover cap dispose towards the right side, and cover cap 47 configuration that keeps left at night, and make night cover cap 46 on than the more forward position of cover cap 47 at night, also be provided with the longitudinal edge 48A, the 49A that are bonded between joint fastener 43,43 and 44,44 and outstanding forward top 48B, 49B on each retainer 48,49, the top 49B of retainer 49 be positioned at night cover cap 47 top and than night cover cap 47 more outstanding.
Above-mentioned each, cover cap the 46, the 47th at night, and the blank of being crossed by any film of fabric lamination is made, this film one or both sides energy permeate water steam, and the film lamination that still keeps its saturating vapour characteristic under low temperature (at least as described later+13 ℃～+ 16 ℃ the temperature) material that forms constitutes, and be wound on torsion bar 51,51 on longitudinal edge 48A, the 49A that is installed on each retainer 48,49 around, to the direction biasing of rolling at ordinary times.
In this embodiment, each at night cover cap 46,47 banner beam overall greater than thermal wall 2 and biside plate width dimensions, these adjacent ends are outstanding to opposition side from the center C of thermal wall 2 left and right directions under reeling condition, then two night cover cap 46,47 above-mentioned end just overlapping on above-below direction.And then make retainer 48,49 as shown in Figure 8 to make also can make above-mentioned as shown in FIG. when cover cap 46,47 other end moves on to the front 3A of foreign side's side plate 3,3 two nights still be overlapping structure at above-below direction at least from installing plate 41 is outwards outstanding.
These at night cover cap 46,47 front end (on slow down) the limit portion member 56 that the hard resin of configuration about them is made is installed, as shown in Figure 6, the length of limit portion member 56 is shorter than the whole width of cover cap 46,47 at night, so night cover cap 46,47 two ends do not have limit portion member 56, central part at limit portion member 56 forms handle 57, handle 57 is made of outstanding forward handgrip 58 and rearwardly projecting clasp 59, and magnet 61 is equipped with in the back of clasp 59.
Each, cover cap 46 at night, 47 front end from above-mentioned canopy eaves 26 and outside the clearance G of dress between the plate 36 go out to peristome 21 laybacks by accommodation section 37, these limit portion members 56,56 as illustrated in fig. 3 near peristome 21 sides outside the accommodation section 37, whereby, two night cover cap 46, though 47 pull out from essentially identical position, since retainer 49 top 49B from night cover cap 47 forwards outstanding, night, a cover cap above-mentioned end of 46 was to fall by the front side of this top 49B, so at least at cover cap 46 at each at night, place, the end of 47 adjacency, along with night cover cap 46 more up walk with regard to more from night cover cap 47 leave and pull to the place ahead.
In above structure, when thermal wall 2 and side plate 3,3 and outer adorn under the state that plate 36 separates are unloaded from open-type showing cabinet 1, each retainer 48,49 is moved inwards and increase the size (Fig. 7) of cover cap 46,47 laps at each at night, increase along with retainer 48,49 so can prevent the width dimensions of thermal wall 2.
In erecting beies such as shops, earlier side plate 3,3 is installed in the both sides of thermal wall 2, again retainer 48,49 is outwards moved, outwards outstanding and night cover cap 46,47 other end is moved on the front 3A of side plate 3,3 from installing plate about 41 as shown in Figure 8, even in this state, night, cover cap 46,47 adjacent ends also were overlapping at least on above-below direction as previously mentioned, then, making limit portion member 56,56 be in to pull down as mentioned above like that does well down, outer dress plate 36 is contained on the thermal wall 2, about seal with cover 38,38.
Utilize this structure, when the close up shop and stop business of shop, catch the handgrip 58 of above-mentioned limit portion member 56,56 pull out two night cover cap 46,47, and each clasp 59 is entrenched on the leading section 28A below the horizontal bar 28, at this moment, because the magnet 61 on the clasp 59 is inhaled on horizontal bar 28, so can keep clasp 59 stably to hook.Again since horizontal bar 28 basically across the whole width of thermal wall about 2, clasp 59 can be entrenched on any position of this horizontal bar 28 leading section 28A, even each, cover cap 46,47 moved on width at night, the chimeric fault of clasp can not take place yet.
Particularly under this state, night, cover cap 46,47 leading section was what to connect airtight on horizontal bar 28 up to its outside (outside), so can close night cover cap 46,47 and horizontal bar 28 between the gap, thereby can prevent that cold air from spilling between the cover cap 46,47 from horizontal bar 28 and night.
Foregoing each, cover cap 46,47 adjacency one end was that above-below direction is overlapping under reeling condition at night, so under the state of pulling out night cover cap 46,47 an above-mentioned end overlap (night cover cap 46 front side), the end then extends outward to front 3A, the 3A position of side plate 3,3 from peristome 21 in addition, so seal between the two night cover caps 46,47 and night cover cap 46 or 47 and side plate 3,3 between the gap, thereby prevented that cold air from spilling from peristome 21.
Thereby, can improve the running efficiency of open-type showing cabinet widely, save electric energy, and do not need the sort of ad hoc wind shutter in the past, so can reduce component count, reduce cost, can move at the width of peristome 21 owing to retainer 48,49 again, just can regulate cover cap 46,47 overlapping dimension at night according to open-type showing cabinet 1 state being set arbitrarily, so that be adjusted to the optimum state that prevents cooling gas leakage.
Particularly each at night cover cap the 46, the 47th, from clearance G, pull out simultaneously, so an end of cover cap 46,47 coincidence at each is connected airtight at night.At this and since night cover cap 46,47 both ends do not have limit portion member 56, so these limit portion members 56,56 can not hinder connecting airtight and connecting airtight on the 3A of the front of side plate 3 of two cover cap 46,47 laps at night.In addition, also by means of from cover cap 46, the 47 inboard gas curtains that descend at each, make night cover cap 46,47 externally be pressed towards storage under the gas pressure and stop up 9 one sides, the two is in conjunction with just further having improved the effect that prevents cooling gas leakage at night.
Therefore, surface temperature at gas curtain effect cover cap at following night 46,47 is lower than+and 13 ℃～+ 16 ℃ (temperature of stopping up in 9 in storage is 0 ℃～+ 5 ℃, when outside air temperature is+25 ℃, night, cover cap 46,47 surface temperature was+13 ℃～+ 16 ℃) time, because night, cover cap 46,47 also can permeate water steam under such low temperature, so can also can prevent as advising in the special clear 42-25586 communique, boring a hole in cover cap 46,47 the inside dewfall at night.Thereby solved the problem that cold air spills from the hole.
In addition, owing to can prevent dewfall on this cover cap 46,47, night can be because of around the stained open-type showing cabinet 1 of dewfall when cover cap 46,47 covers the outside of horizontal bar 28 as previously mentioned yet at night.
Because the above measure that prevents cooling gas leakage arranged, this embodiment compares its power consumption with the existing open-type showing cabinet (100%) that has cover cap at common night can reduce to about 55%.
In addition, in foregoing accommodation section 37, at least the cover cap 46 at night of the end parts that night, cover cap 46,47 adjoined each other past more get on more away from night cover cap 47 towards the place ahead, so each, cover cap 46,47 can not disturb at night when reeling, and can improve 46,47 o'clock the operating characteristics of cover cap at night of pulling out and reel.Again since each at night cover cap 46,47 be mounted within the accommodation section 37, so can also improve outward appearance.
Following Fig. 9 links the plane that is provided with two open-type showing cabinets 1,1.In this embodiment, its at night cover cap 46,47 with Fig. 1 to Fig. 8 occasion in opposite up and down.Be to have saved the side plate 3 of two open- type showing cabinet 1,1 sides adjacent and thermal wall 2,2 is bonded together in this case, between each thermal wall 2,2, can form a little gap 63 by encapsulant.
Yet, under each as previously mentioned cover cap adjacency one end overlap condition of 46,47 at night, the other end is protruding from peristome 21, just can make cover cap 46 the right-hand member at night of the open-type showing cabinet 1 in left side, and is overlapping with cover cap 47 the left end at night of the open-type showing cabinet 1 on right side.Thereby close and gap 63 between each thermal wall 2,2 between the cover cap 46,47 at night of each open- type showing cabinet 1,1, prevent that cold air from spilling from peristome 21,21.
