Description

Multifunctional window support

Affiliated technical field:

The present invention relates to support the object that flat opening window, cabinet, door etc. need support.

Background technology:

At present no matter what be that the building window of metropolis or small and medium-sized cities mostly uses is the flat opening window, we all ran into the weather sweltering heat of two season of spring and summer open a window ventilate prominent meet to blow hard have little time to close the window, cause window fiercely to close sash and window frame exertin folding collision, the serious window that causes damages or the glass fragmentation.Though also can support window with iron rod or waddy, can only reach maximum to window and just can block sash, know people sometimes be unwilling window open too big, so can't regulate window folding size; For urban family, generally is not easy in addition to can not find and is fit to the waddy or the iron rod that support, and waddy is easy to lose, or the positive time spent of spring and summer sky in the coming year such as do not open a window in the distortion that gets wet that fractures, especially a winter can not find, be very much trouble.

Summary of the invention:

This window support is different from the sort of rod of only fixing by the ability that is stuck between the window, can clamp window with clip, can shorten according to the folding size elongation of window, wins conveniently; The cupboard, door etc. that can also support cabinet, Ping Kai and folding up and down need the interim object that supports, and not only have support function also can work as drying rack and use, support tent or the like; The tourism of going out, easy to carry, so be multi-functional, multiduty eyelid retractor.

The technical problem that solves: people worry that when daily use casement window ventilates strong wind scratches window and often runs into the situation that the object that is fit to support supports sash and window frame that can not find, fasten, open big, looking for article to block sash conveniently fixes, it is very much trouble, adopt the scalable technology of support bar based on this this eyelid retractor, the time spent is not withdrawn it, adopt clip to fix window frame and sash, can conveniently win like this, (though some window carries support bar, and the sort of support bar is fixing dead cannot taking off, and window reaches a dimensioning and could support); Can regulated at will and fixed sash folding size, and need not be as reaching the maximum defective that could fix in the middle of being stuck in rod again to window in the past.

Two, the most important technology of this window support, and ' more piece support bar simultaneously flexible technology ' are exactly this eyelid retractor core technology, have only two section telescopic bars before having solved or are exactly two joint fluid pressure type expansion links, and never two joints are with upper support bar.It is half of its elongation that two joint support bars retract length, even if return also to be inconvenient to carry for long support bar is full reduced, unless the total length of elongation is done weak point, Suo Hui length shortens naturally like this, but the not enough supporting object of total length is so exist such contradictory problems always; Though also can utilize hydraulic technique to be made into three joints for the hydraulic pressure support bar, like this fastness that supports will be influenced, and is firm not as two joint supporting objects certainly, so the hydraulic pressure support bar that we see at ordinary times all is two joints.I also expect making of hydraulic pressure the support bar of window support at the beginning, but it is general to consider that butcher's knife government official chicken is really wasted one's talent on a petty job, cand be compared to its support degree, and its cost is higher.Therefore the technology of the present invention has just solved this type of technical barrier, and this window support just adopts this ' the flexible simultaneously technology of more piece support bar ', we can say that also this technology is born because of the invention of this ' multifunctional window support '.

Technical scheme:

This product mainly adopt four joint retractable supports bars, inner telescopic folding device, two ends separately a clip form, support bar is a cylindrical shape, make (metal such as available aluminium alloys with metal material, the for example commonly used mop bar of family, the Metallic rod material on the window-cleaning device), divide four joints ascending nested combination, for being to elongate and to withdraw; Make by metal material in the clip of two, outside by blue plastic layer parcel, in order to be clip and support bar overall appearance; During use two clip is clamped window frame and sash respectively, after adjusting sash folding size, turn round and to fix by the latch on the lower support bar, can press latch in the use at any time once more and turn round the folding size of regulating window, so just realized conveniently supporting window.

Beneficial effect:

Characteristics because this eyelid retractor adopts retractable supports bar and clip to fix window, so be easy to use, fast, practicality, and can not only support window and can also support cabinet, door etc., so also have multi-functional, versatility.

The specific embodiment:

Using method: during use the clip on window support right side is clamped window frame, the clip in other end (left side) is accommodated the sash of glass, sees Fig. 9---Figure 12:

Figure 10 for make clip firm clamp window frame, clip opening and closing degree when making is critical (and elastic force of spring), the part that is connected with support bar is in the medium position of clip spring to folder mouthful distance, so just can be more firm clamp window frame and do not become flexible easily.

The clip of other end is accommodated the sash of glass, Figure 13 as follows---Figure 14

After Figure 14 clamped window, eyelid retractor was regulated according to the size of window folding apart from length, and the jack that aligns is then turned round by the latch on the lower support bar, got final product fixed support device length, the folding size of having fixed window simultaneously.Figure 15 as follows---17

Figure 17 eyelid retractor fixedly behind the window maximum folding distance be approximately 84 centimeters, (concrete length can be regulated) in process of producing product

Each parts is introduced in detail:

Support bar: support bar is by four joint metallic cylinder descending nested compositions, for being to stretch.Support bar can adopt material such as stainless steel or aluminium alloys, following Figure 18,19

Blue blockage above Figure 18 support bar is that latch is turned round, and pressing green button can fixed support bar collapsing length.The two ends blue portion is a seal closure, adopts plastic production, plays a part to fix and link clip.Internal structure:

Can pull out simultaneously in order to make four joint support bars, give support bar inner one ' telescopic folding device ' (the sort of flexible scissors that child plays before being exactly of installing, one is the scissors handle, the other end is fist or other and so on, the sort of toy of making of plastics, with hand once pinching a scissors extending or withdrawal), make in this way, just can realize pulling out simultaneously four joint support bars, see Figure 20 sectional view

Figure 20 (sectional view) yl moiety is exactly ' a telescopic folding device ', form (specifically can increasing according to the length of support bar or reduce) by 20 joints with how many joints and every pitch width degree, two combined crosswise are a joint, every wide about 4-5 millimeter, vertically being about is 1.9 millimeters, just in time coincide with the thinnest that root support bar interior diameter of the 1st joint; The blue cross bar in two is used for linking yellow expansion link, and white cylinder is to be used for fixing them.The vacant place of three row's circles is the joint of every joint, and the blank area drawing is watched so omitted to white cylinder for convenience.Two red loop pillars are fixed second joint and the 3rd specially and are saved support tubes and use.

Figure 21 only need pull out one and just can pull out middle two joints and second, third joint simultaneously (annotate: number is first segment, second joint, the 3rd joint, the 4th from left to right) like this

Figure 23,24, telescopic folding device side view

Figure 23---Figure 27 is that second joint and the 3rd saves support bar and how to be connected and to link the telescopic folding device, 4 elongate rod that connect the telescopic folding device are metal material identical with support bar, and can realize behind the red partial fixing in the folders that saving support bar with the two or three when the first and the 4th pole pulled out also pulls out.Latch is turned round and how fixed support bar introduction:

Latch button (be called for short latch turn round) adopts pressing, clicks fixingly, clicks and upsprings, and for example our common electrical socket switch is the same, as Figure 28---shown in 30 downwards by green button

Because first segment and the 4th joint are fixed with telescopic folding device two, the two or three joint is also fixed with the folders mid portion, like this only need fixing wherein two the 3rd joints just can fix whole support bar with the 4th support bar, so as long as on three pair rod, beat several circular holes, and need not all plug pin-and-hole by every joint, so just, four support bars (also can claim: the more piece support bar is technique for fixing simultaneously) be can realize fixing simultaneously, Figure 31, Figure 32 seen

Do 9 equidistant circular holes altogether, can regulate support bar length arbitrarily, the latch button clicks fixing, clicks and rebounds, just regracting and elongation support bar.

The two ends clip is introduced: left side clip

Be changed to metal material in the clamp material, shell is a plastic wraps, and blueness is seen Figure 33---37:

Figure 34 and the not too big difference of our common clip, the spring that the axle center is made by steel is formed; It is that elastomeric material is made that clip dehisces to locate black band toothed portion, for be increase and caught object between frictional force, the more firm object of clamping

Figure 36 is the expansible clip with two finger presses upper end

Be the right clip introduction (scalable clip) below: see Figure 38---51

The outer shape difference of Figure 38, except that can stretching, structure does not have much difference clips to look wideer than the left side with the clip on the left side, arc, why being designed to is in order to stretch like this.Why will be designed to telescopic clip: the window frame of some window is thicker than broad, words remove to press from both sides window frame with regard to the clip of handy lengthening like this, common, narrower window frame can't have been clamped again, so be designed to promptly can press from both sides thick window frame, the multi-functional clip that also can press from both sides thin window frame is more satisfactory, that is: scalable clip (also can be named: extending clip).See figure: 42-46

The window window frame that general plastic-steel material is done has two centimeters limit, just in time can directly clamp and need not extend with clip, but the window that has a kind of aluminum alloy materials to do, it sees Figure 47-49 by the window frame of the one side of glass is baldr: talk about like this, must extend clip, clamp stupefied one side on one side, another side is clamped by the glass place and is got final product, and sees Figure 49---Figure 51

Replenish: since clip is scalable so, but how to fix (promptly keeping not withdrawing after the clip elongation), the paper knife stretch mode that fixed form will adopt us to live common, the black slide block of for example pressing pushes away forward and can release blade, clicking to pusher and can regain blade, so this flexible clip also adopts this principle to fix and the clip that stretches.

The flexible function of clip:

Lateral bending song: as Figure 52,53

Design one is in order to prevent that use from fractureing clip in the support bar junction like this, the 2nd, can make have a down dip on the eyelid retractor clamp and support window frame, and needn't only be fixed on the horizontal linear.

Front and back are crooked: (Figure 54---58)

Strutting two, back simultaneously can be crooked, as Figure 56---and 58

The bent general view (Figure 59,60) of lateral bending

The rotatable function of left side clip: see Figure 61---66

Figure 62 can rotate flexibly towards different directions

Design is in order to make two clips clamp window frame towards different directions like this, thereby applies in a flexible way.Be designed to have only the clip rotation on one on the left side to get final product, designing one like this is to consider to save cost, if two clips can both rotate and not have much meanings, rotation just can make the two ends clip rotate towards different directions so have only on one side.How clip rotates and internal structure: flexible clip is connected on the reeded base, and base is connected and fixed in the seal closure of support bar again, can realize freely turning to, as follows Figure 65,66

But clip plug function: (Figure 67---83)

Two clip can be extracted, consider the extensive use of this window support, can not only support window, door, cabinet of flat opening etc., can also be used for can't be with the fixing objects such as the cupboard of opening-closing type up and down of clip, these objects directly support more convenient with support bar, support object such as tent when for example travelling temporarily, support bar can also be worked as drying rack and be used or take temporarily some towel underwears and so on, also can one extracting a head-clamp object uses ... therefore be designed to can plug clip, also shown the versatility of this product;

Support bar sealing two ends cover respectively has the groove of four symmetries, is used for plugging in clip and covers jut, sees Figure 68---and 70

Figure 69, Figure 70 have the inside groove of four strips inside, and effect is, with four juts on the clip sit in the right seat inject after, screw again to four rectangular capable grooves and can fix.

Be used for and the fixing part introduction of seal closure Figure 71 on the clip---73

Four square protrusion parts and four square grooves of support bar are sat in the right seat and are inserted, and see Figure 74-76

After the reeve, catch clip one to hold support bar on the other hand, make clip rotation counterclockwise left, can make clip and support bar fixation, as Figure 77---80

Two ends can unplug, and just can support objects such as the cupboard of taking off lid up and down, chest then, see Figure 81-83

Even if the introduction of above product content is over, window support model picture is to form with the 3Dmax software development, in sum, concludes and gets up can be divided into 4 big technology:

One, the flexible simultaneously technology of more piece support bar (comprise telescopic folding device and with the combination of each parts of stay pipe)

Two, flexible, the rotatable technology of clip

Three, scalable clip technology

But four, clip plug technology

Be combined into a big technology by these four technical characterictics, that is: multi-functional eyelid retractor, it is quick, of many uses to be easy to use, and not only can support window, and the cupboard, door etc. that can also support cabinet, Ping Kai and folding up and down need the interim object that supports; Not only there is support function also can work as drying rack and uses, the tourism of going out, easy to carry.

We all ran at home the weather sweltering heat of two season of spring and summer open a window ventilate prominent meet to blow hard have little time to close the window, cause window fiercely to close sash and window frame exertin folding collision, serious cause window damage or glass fragmentation.Though also can support window with iron rod or waddy, can only reach maximum to sash and could block sash with waddy or iron rod, sometimes people be unwilling window open too big, so can't regulate window folding size again; For urban family, generally be not easy in addition to find to be fit to the waddy or the iron rod that support, and waddy positive time spent of spring and summer sky in the coming year such as do not open a window in distortion, especially a winter that is easy to fracture or gets wet can not find, be very much trouble! Based on this, I design this product, the use that makes people can be convenient, fast in life, save time and save worry! And travel away from home, easy to carry! Give own the creation the convenient while,, can also give and ownly bring economic interests with society, the drive social employment also to others' convenience of having taken.

Market analysis: now no matter what be that the building residence window of metropolis or small and medium-sized cities mostly uses is the flat opening window, having the building of sliding sash to be still occupies the minority, trace it to its cause, at first frequently the sliding sash cost is cheap mutually for casement window, so adopt casement window when most of real estate developers found a capital the building, the 2nd, people generally like with casement window because casement window use than sliding sash and top hung window make things convenient for, switch is easy, and sliding sash and top folding are relatively required great effort, and the time has been grown parts such as roller and broken down easily.Should the strengths and weaknesses of self all arranged separately, but compare each side such as cost, it so is the window that main flow is used that casement window is appointed.So this window support is definitely commercioganic.

The retail price aspect: the cost of production decision of this window support is controlled in 5 yuans, retail price is at 10 yuan---and 20 yuan, specifically can decide according to various places economic consumption level, even if I think 20 yuan, large, medium and small city is with the present price of China in various places, 20 yuan consumption also is very common price, therefore people can bear up, and each family all needs at least one such eyelid retractor, at least need 2-3 if popularize every family that comes, because the each household family can not have only a fan window.If count the office in enterprise and the unit again in, this produce market is with boundless.

The versatility of this product: more than be the market analysis that multi-functional eyelid retractor is used for window, it can not only support window and can also support door in fact, some door is not installed wall when mounted and is inhaled when meeting very big draught, wind is fiercely closed door suddenly and is caused a damage or doorframe and body of wall shake pine easily, so door also needs the bracing or strutting arrangement of external application, such as needing summer door window to ventilate, sometimes wind is from blowing inward outside window, and the door self-defect wind that has has gone back once blowing to close, living door with garbage can or chair shelves can be plain again, also be in the way, so live above the door-plate with eyelid retractor one head-clamp, doorframe is clamped in the other end, door-plate then leaves Da Cheng 90 degree by wall, eyelid retractor is to snap into the upper end of door by corner, rotatable clip at this moment just can one presss from both sides door-plate one upside down and head-up presss from both sides doorframe, and eyelid retractor has played the effect of blocking door-plate and doorframe makes door firmly motionless, and do not go back in the pass of being scraped by wind;

I think that the friend that we live building also ran into this situation, sometimes we think to tremble clothes outdoors or get thing and so on, can not want again to close the door, because building all is a security door, one closes the door must turn the key in the lock, just say also the time a little while again, stay a crack between a door and its frame once when going out so people are just lazy, but sometimes meet draught suddenly barring up that door blows, be not with key this moment, the household does not just in time exist yet, and this can be just not easy to handle if the household is not with key yet, and the master worker that have to spend to unblank unblanks to the doorstep.So supporting with eyelid retractor when opening the door avoids accident to close the door temporarily;

Also having a kind of door is the folding automatically of band spring, the inside and outside can both be opened the sort of, glass door panel door limit is metal the sort of, this door majority is that unit for example uses public place such as hospital, if someone removes thing cargo transport, goods is many again, inlet/outlet always closes the people automatically and advances once to open once back and forth, if support not difficult to find again also occupation of land side with chair, if a people is holding up the people of the words carrying of people's carrying of door relatively to tire out and is wasting time again, if moreover staff is not enough just not easy to handle, support so just need this eyelid retractor as this door in this case, get twice the result with half the effort.

It more than is the support function introduction of multifunctional window support, except support function, it can also work as the clothes-horse use in fact, when we support window with eyelid retractor, we can hang over towel, rag etc. above the support bar simultaneously, and window is being opened and is being ventilated, make fast that clothing such as these towel rags does on the contrary, even if not clamping window also is fine when clothes-horse with it specially, for example, the family corner so long as there is the place that can press from both sides at two, can press from both sides with eyelid retractor as nail in the walls, upright water pipe etc.; Outdoor function: camp out of doors, can clip to eyelid retractor on the branch when travelling, between two crotches; Or two clip take down with the they sup-port tent can, his property of many uses in a word can be developed its atypical function voluntarily in user's use.

Replenish: because eyelid retractor initial design thinking is the mentality of designing according to Fig. 1, considered afterwards that crooked radian should be left in the clip centre on the left side, and can clamp window frame more closely like this.See Figure 84,85.
