Description

The two button box devices of ventilation invisible

Technical field the present invention relates to fixed or moving door and window, the window shade (E06B) used at the opening part of building, vehicle, fence or similar surround.

Background technology

At present, door and window, the curtain of ventilation invisible function arranged, take the blinds principle as main, exist deficiency.

Analyze first the curtain class.

At first see the common cloth curtain that our every household has.Its dress method generally is, window opening by indoor outer above, put slide rail, curtain box, hang up cord.Cord is overlying on window opening outward, and that distance of the cord that dangles and metope is air flue;

Two limits and three following limit air flues about cord are so that during the closed curtain in the bedroom in evening, circulation of air is enough reluctantly.But well-known, the building of developing now, the window opening form is most to be " window wafts " (bay window), the glass window of evagination mostly is corner, even cambered surface, what form in the window is extra, broad windowsill, be fully utilized, put, it is many that other has also put seat, bedding---thus, cloth curtain is also had to along with " indent " changed, namely put curved rail at the window opening top of evagination, curtain cloth, two limits are substantially being pasted glass and are being walked (distance large just " exposure ") about cord, the base is being pasted windowsill and is being walked, and like this, the air flue of " recessed curtain " has not just had substantially!

See again on the market existing two classes " Ventilated sight-obstructed curtain ": blind and two roller shutter (zebra curtain), also Shortcomings.

Have unearthed relics to prove, China Eastern Han Dynasty before two thousand years has just used " San " word shutter principle the earliest.Before in 1 hundred 50, the American has invented common now blind.But problem, the difficult problem of blind are a lot: 1. on function, " low light level blinds on daytime ", " decoration blinds " in fact, once useless to evening, be ventilation, view resistance function conflict, incomplete: adjustment of blade angle has arrived basic view resistance, and is also just substantially stuffy; Blade is very wide, just easily with extraneous sight line guide to extremely near window, away from roof or the ground of bed, but words so are whole just very thick and heavy.(" pile V " formula blinds principle is regulated inconvenience, can't be used for curtain, only is used under the bathroom door.) 2. in the use, involved by a large amount of ropes, very easily malfunctioning; The blade of common thin aluminium very easily is out of shape, loses by wind, thereby " exposing ".3. aspect sale, popularization, accurately measure to the doorstep window opening by curtain shop everywhere first, pass to producer's cut-parts, serial connection again, it is customized to belong to typical personalization, can't produce in enormous quantities, so manufacturing cost is very high.Then, casual household's enquiry that this is sparse is transported to the curtain shop again, and freight charges are high again.Because this thing deadweight is very heavy, the user often opens and closes up and down again and drags rope, and the hotel owner must take the wall hammer drill to the doorstep, objective firm installation of generation.Like this, hotel owner oneself can not manufacture, and sells on a commission basis, installs, and takes time and effort, pretty troublesome, and with regard to leading oneself traditional door curtain made of cloth, the enthusiasm of promoting blind is very poor.4. the structure of its " anyhow, hard heavy ", inadaptable now two large window type trend: the one, " bay window ", " arc window " trend---this good understanding; The 2nd, " windowing greatly " trend, i.e. window opening very roomy (" gigantic " soon), and fragile blind inconvenience makes very wide length (in addition it is also unsuitable to advance corridor, elevator), must several splicings---bother and easily expose.Its decoration significance is much larger than practicality so blind is come into far away huge numbers of families! Particularly there are not several families dare to be used in bedroom, washroom.

Recently the Korean has invented two roller shutters, and in the existing agency of China, production, market begins to start.Principle is the arrangement of being separated by of wide cloth and gauze, two major parts, up and down scrolling before and after being divided into by the top spool.What it was better than blind is, fully view resistance and ventilate (cloth namely is relative with the net bar).But its deficiency is that 1. actual draught area and its ventilation otch area (being the gauze area) ratio are too small.That is, actual draught area be not every gauze front look roomy like that, but the such slit that is determined by the spacing---arrow path---of two of front and back.2. when regulate night, because the outside is dark light is arranged in the room, seeing away does not have reference, and it is no to be difficult to judge that adjusting, scrolling put in place, does not slightly note, exposes! 3. it moves up and down, structure, manufacturer's setting-out and hotel owner such as can't make by oneself at the characteristics anyhow, bring the deficiency the same with blind: be not suitable with that window type trend, cost are high, the hotel owner is without promoting enthusiasm.In addition, they clean also inconvenience.

See again relevant door and window.Such as bathroom door, because " water funk ", the main product of door is " doorframe+ground glass of aluminium alloy extrusions+blinds " between domestic hygiene at present, but traditional blinds is shaky, not attractive in appearance, increased cost of manufacture, under the harmful competition of homogeneity, most of producers have exempted to fill blinds---but thus, 1. do not meet relevant ventilation safety standard (China Department of Qulity Supervision and the Ministry of Construction unite issue [dwelling construction standard] regulation: " the bathroom door bottom should install and fix blinds, its net sectional area must not less than 200 square centimeters ").2. although the washroom window has been installed exhaust fan, bleed in the ground at the bottom of crack between a door and its frame, air inlet, and the one, its crack between a door and its frame airway cross-section is not nearly enough less than 200 square centimeters, and the 2nd, some users can produce and detest psychology.3. because door leaf is removed the assembly unit blinds from, the height (material reducing) of door leaf has just shortened in many producers, raising crack between a door and its frame, satisfy to ventilate, but this is just taken on the sly, peeps easily---many houses will hire out share to others---, and this structure is just unreasonable.

In the today that focuses on the people's livelihood, improves quality of the life, guarantee " live, sleep " quality, advocating natural ventilation, family's economize on electricity (can turn on the aircondition less, electric fan), needn't worry to spy on (possibility of taking on the sly, spreading is arranged) outside window on the net, feel at ease to go to bed, is everyone demand! But only this simple curtain does not have preferably solution so far.

Summary of the invention

The two button boxes of ventilation invisible provided by the invention are fastened on the common cord, are the ventilation invisible curtain, are opening and closing left and right, can simply, fully realize ventilating and view resistance, and actual draught area also greatly increases; Base fault-free, malfunctioning.The hotel owner even the user can conveniently make by oneself, install; Easy cleaning; Cost is low, easily promotes.Be fastened on the glass of door and window, make door and window conveniently become the ventilation invisible door and window.

The technical solution adopted for the present invention to solve the technical problems is: with Shooting Technique make two relative, totally be the button box of shallow tubbiness, two button box common ground are, by at the bottom of the bucket and perisporium form, the button box of shallow tubbiness is erect, perisporium can be divided into roof, diapire and about two walls, four major parts; Closely knit, the monoblock of roof, two walls are real to be blinds, forms the side pore between blinds; Bucket end projection has the connection recess.The difference of two button boxes, the one,, the inner bulge of the roof 1 of a button box has the selvedge card convex 2 that is higher than its top, and also extend blinds the inner, projection is selvedge card convex section, and another then needn't; The 2nd,, the part between the blinds of a button box, at the bottom of bucket has positive peripheral pore, and another relative button box is the mid portion at the bottom of bucket then, has positive central pore, and the peritreme of this positive central pore is enclosed 2 by view resistance and is held.But end of blade face sawtooth.Button box can be rounded, rectangle etc.If circular button box, its diapire and about two walls be all blinds, form impeller.Like this, hold large mouthful 4 of some ventilation successfully at cord, ground glass, with its roof selvedge card convex and grille cloth checkpost protuberance that is enclosed within button box, fast decided the position, again another button box is buckled, finish fastening by magnet or screw.The result is, sees the button box of the inside from the button box of cord (glass) outside, if from arround see crossing the offside of (button box), mutual blinds, " seeing not saturating "; If see over from positive (i.e. the outer bottom at the bucket end), because of holding up that view resistance is enclosed, also " see not saturating ".Under the prerequisite of this view resistance, (button box) serial side pore of cord (glass) side, the sectional area summation of front pore can approach even be equal to the large mouth that ventilates, and realize " opening much holes, logical how much wind ".

The invention has the beneficial effects as follows: light and handy button box can be made in enormous quantities, and color can be rich and varied, and hotel owner, user can purchase button box, and the cloth of liking by oneself is assembled into fabricbase curtain, the bathroom door of ventilation invisible, and is inexpensive.Convenient family expenses of popularizing not only also can be applicable to sick bed---and the slide rail on the ceiling, pulley are hung the long filament hook, tangle this cord again, namely become simple and easy " cloth partition ", and the changing dressings of the human body of both having felt at ease, treatment and daily life do not affect again circulation of air.To numerous woman workers, schoolgirl's dormitory, not only can be curtain, also " bed encloses " of usable as personal.Application surface is very wide, benefits huge numbers of families.

The specific embodiment

The present invention will be further described below in conjunction with drawings and Examples.

Introduce first " circle box ".Fig. 1 i.e. one of two boxes, the closely knit roof of a monoblock 1 are arranged, anti-dust fall at the bottom of its barrel; The inner bulge of roof 1 has the selvedge card convex 2 that is higher than its top.Its diapire and about two walls be blinds 3, form impeller; Blinds 3 inner extensions, projection are selvedge card convex section 4.The middle part has positive central pore 5 at the bottom of this box bucket, and positive central pore 5 has held view resistance and enclosed 6, (the inner ring view resistance is enclosed low).Bucket center, the end also projection has and connects recess 7, notices that its structure can walk screw or support magnet.Fig. 2 is seen in the cross section.Intuitively see Fig. 3.

Fig. 4 has positive peripheral pore 8 for another circle box, sets up reinforcing rib 9.Note the rotation direction of this box impeller for reverse, during with another box fastening, namely comply with mutually.Fig. 5 is seen in the cross section.

The fastening of the namely two button boxes of Fig. 6 and cord, sight line arrow signal view resistance principle; Middle its connection of signal, fastening, except available screw, also can be by magnet 10 absorption.(China is rare earth main product ground, and ndfeb magnet only needs little by little, and suction is enough! ).

Fig. 7 shows same as button box, can fasten with thicker glass of door and window, should be by screw tightening.

Fig. 8 is the cross section of rectangle button box, but wherein shows blinds end face sawtooth, when synthetic curtain, can strengthen the snap-in force to cloth.Fig. 9 shows the fastening of they and glass.Because this injection mold is comparatively meticulous, complicated, cost is not low, so a mold to thin, the folder of thick material, button, should have preferably leeway, versatility.As seen, the view resistance of this programme is enclosed 6 height and is stayed higherly, and versatility is just better.Prerequisite is can not affect, reduce the positive peripheral pore at its opposite slightly to the right or left around the sectional area of the inside air flue that gas is come, and namely the position 9.Figure 10 is the longitudinal section (part, width ratio 1: 1) of the two button boxes of rectangle, has illustrated the view resistance of louvre blade offside pore.Figure 11 illustrates the positive central pore 5 of elongated of rectangle button box and the view resistance of corresponding elongated to enclose 6, connects recess 7 with being connected.It also is reinforcing rib that the view resistance here encloses 6.Figure 12 shows positive peripheral pore 8 and the reinforcing rib of another corresponding rectangular box.Figure 13 then the side illustrated blinds 3 and between side pore 10.

At present the bedroom timber has the trend that installs the daylighting heavy sheet glass additional, sees Figure 14, on this basis, on glassly opens round hole, this round buckle box is installed, and just becomes simply the ventilation invisible door! This is that door is seen in the outside, bedroom.Figure 15 is that the inside is seen, signal must be established and be covered gas self-adhesion press strip (adsorb magnet of wicket does not represent in this) around " door in door ", the glass, like this, except sleep, the damp mould season of most of time, need open outside the spacious gas of wicket, when conjugal affection has sound, the hot summer and bitter winter be in the time of need turning on the aircondition, and can close wicket.Consider the thickness of button box, glass, and necessary little thickness gate (wicket is too thin, easily shakes transaudient), the bedroom door of 42mm, 45mm standard thickness, suitable this ventilation invisible scheme that adopts.The local amplification sees Figure 16, and simultaneously signal can load in mixture, fill more button box, to strengthen ventilation.The sleeping bedroom door of energy natural ventilation, at present, the world market almost is blank---secret is, sometimes must cover gas, then this behind the door face must add wicket in the certain thickness door, like this, the thickness leeway of leaving preposition ventilation invisible device for is just very little, and traditional blinds, after the view resistance, the thickness difficulty is fallen, and is difficult to be competent at.So the thickness of ventilation invisible device is thin, it is decisive factor! This button box principle is a solution.(other several scheme separate cases are applied for a patent.)

This bathroom door scheme of Figure 17,18 for removing shutter from.If some the time, " down draught " of wind direction when phenomenon is serious, can muffle with plastic paper temporarily with the upper button box of the door in the washroom, puts rubber band and gets final product.In addition, because toilet wall has ceramic tile, do not fear rainwater, this button box also can directly be contained on the washroom window-glass.

Figure 19 is the multiple button box layout of this curtain.Figure 20,21 have shown can the suit advantage of bay window of this curtain.

Although relevant Ventilated sight-obstructed curtain, the ventilation of bedroom door, there is no at present the world, national standard (may be because this class " ventilation invisible " demand gets the brush-off in the past, more may can't finely meet the demands because of the existing product before this programme), but [the dwelling construction standard] of uniting issue with reference to China Department of Qulity Supervision and the Ministry of Construction: " the bathroom door bottom should install and fix blinds; its net sectional area must not be less than 200 square centimeters ", reach [the disaster relief that Ministry of Civil Affairs and the General Logistics Department of PLA unite formulation, military paulin room standard]: the requirement of " ventilative window size must not less than 100 square centimeters per capita ", for the man and wife bedroom, also can be with reference to adopting 200 square centimeters of ventilations.Calculate case of the present invention: 1. the round box of this diameter 10cm, but the cord of support diameter 8.5cm ventilates large mouthful, and namely this ventilation section can entirely be crossed and ventilate large mouthful, is 56 square centimeters, namely detains 4 pairs of round boxes, just can be higher than related standards.2. the rectangular box of this diameter 6.7cm * 34cm, but the cord of support 4.8cm * 32cm ventilates large mouthful, and namely this ventilation section can entirely be crossed and ventilate large mouthful, is 154 square centimeters, namely detains 2 pairs of round boxes, with regard to more than 300 square centimeters, far above related standards.Few button, unconsciously enough, do not feel oppressed; Many buttons can feel obviously that gentle breeze strokes face.The more the better.
