Description

Sunshade

Technical field

The present invention relates to sunshade or ante-venna, it can be installed to any suitable support member (for example, exterior wall of buildingOr separate frame or pillar) and its can stretch out to provide shady and cool or retract to deposit.

Background technology

In whole description for any discussion of prior art do not represent admit the prior art be known orForm a part for common sense in this area.

Building or other structures can be provided with the permanent or semipermanent sunshade of rigidity; It is crested region effectivelyThe little local roof of top, although they are firm, has obvious shortcoming, and, in the time not needing to cover, they are notCan be removed.

For removable sunshade, it must be designed to can remove completely in the time not needing, and (this is generally inconvenientAnd labour-intensive) or all or in part sunshade must be designed in the time not needing to retract or to fold up.

The regracting sunshade of conventional design comprises and is fixed to supporting construction (for example, the wall of building) along an endSupport frame to make it protruding from building, and it is supporting the covering of flexible material, covering can be at frameIn the part of frame or whole length, stretch out to cover desired zone, or support knot towards being fixed to of covering when not in useRetract backward in the end of structure.

The most simply one of design of the type is improved roller blind in essence: the flexible material of-formation coveringBe wound on spring-loaded roller, roller is arranged near a described edge of framework, in the time that needs cover, by flexible material fromOn roller around under, the spring load by roller keeps tension, and is fixed in the frame edge contrary with a described edge. ShouldDesign is simple and for manufacture, is cheap, and the advantage having is in the time that flexible material is wound on roller, softProperty material is only exposed to weather minimum level, but its major defect is flexibility in the time that flexible material reaches hidden positionMaterial is not supported well, and easily suffers windburn and damage. The deficiency of flexible material support member also means thisDesign is only suitable for little sunshade.

Above-mentioned shortcoming can be overcome; For example, described in patent NZ336577, it has disclosed a kind of sunshade design,Wherein by rib support flexible material, rib along the length of flexible material with the spacing that separates across frame width prolongStretch. The engaged at end of these ribs is along the track at frame side edge, with make sunshade in extended position by fine twelve Earthly BranchesSupport and be not easy to suffer windburn very much and damage. The support that gives flexible material by rib also means that this design can be used for greatlySunshade. But the shortcoming of this design is that flexible material is suspended between rib as ring in the time that sunshade is retracted, with frameThe bearing edge of frame is adjacent, and the ring of flexible material has the trend of the dust of collecting rainwater and be blown up, and flexible material originallyBody is exposed in weather.

Detailed description of the invention

With reference to Fig. 1-4 of accompanying drawing, sunshade 10 according to the present invention comprises the framework 11 of rigidity, and it is square on planeShape, there is first end 12 that is suitable for being fixed to support member (wall of for example building or independently pillar), usingTime from the outwardly directed relative end 13 of support member, the relative side 14,15 parallel with two that are connected end 12,13.Framework can be made up of any firm, material impact-resistant, antiultraviolet, the steel of for example coating powders or aluminium alloy.

Side 14,15 can be only supported and/or supported every a segment distance along its length across its ground, end,This depends on the length of side. If side 14,15 is supported along their length by multiple crossbeams, can save end12, one of 13 or these two ends all save.

The end the 12, the 13rd of framework, simple support bar; Side 14,15 is formed as channel-section, and channel opening is towards frameworkInside.

For major applications, framework 11 is arranged to stretch out from support member, and the plane of framework is in substantially horizontal flatIn face, but sunshade of the present invention is by operating in the situation that framework is in any orientation satisfactorily, even at frameworkThe situation of plane in vertical plane under operate.

The size of framework 11 is a bit larger tham the area that need to be covered by sunshade; Can regulate its size and ratio be applicable to wantAsk. Frame Design becomes for good and all or semipermanently to stay in correct position.

Sunshade 10 extended/regracting part comprises the flexible material 16 of rectangle length, its be slightly narrower than framework inPortion's width and the length of being slightly longer than framework. An end 17 of flexible material 16 is fixed to and is wound on rolling-up roll 18, volumePlaying roller 18 is positioned near the end 12 of framework and is parallel to end 12. The end 19 of roller 18 is arranged in bearing (not shown), shouldBearing is fixed on the side 14,15 of framework adjacent with end 12. Rolling-up roll 18 is arranged to by the direction along arrow A (only Fig. 3)Manually or by any drive unit in known drive means (not shown) scope drive. Preferably, by being arranged onMiniature motor in roller provides power to rolling-up roll 18.

Flexible material 16 can for good and all or semipermanently be installed to roller 18 but preferably (for example, pass through removable deviceShackle connects) if be attached to roller 18 to make flexible material 16 wear or damage, can change flexible material 16. Flexible material16 can be the material of any suitable tough and tensile, antiultraviolet, for example, and the knitting of canvas, sheet plastic material, plastic coatThing.

The flexible material in extended position 16 shown in Fig. 1 reaches end rail 20, flexible material from rolling-up roll 18Outer end 21 for good and all or by removable shackle be affixed to end rail 20. In order to allow that flexible material 16 is from rolling-up roll18 around lower and move to extended position, and rolling-up roll 18 can depart to allow that rolling-up roll is along contrary with arrow A with its drive unitDirection rotate freely.

In the extended position shown in Fig. 1, flexible material not only rolled-up roller 18 supports with end rail 20, and in quiltBetween rail 22 support, there is shown three in mid-rail. Should understand, depend on the total length of sunshade and sunshadeExpection wind load, the quantity of mid-rail can increase or reduce. May only need single mid-rail 22 for short sunshade.

The object of end rail 20 and mid-rail 22 is support flexible material opposing blast :-ascending air and downdraught make softProperty material 16 is flapped and may cause rapidly remarkable infringement. End rail 20 and mid-rail 22 are all separate type rails, in Fig. 3 and 4Shown in :-each rail 20,22 is actually a pair of rail parallel to each other and that only link together in their end. Each separationEvery tracking in formula rail is connected by arm 23a, 23b respectively in each end, and arm 23a, 23b are also fixed to connecting plate 23, connectsPlate 23 provides the connection of firm and rigidity and supports the roller 24 that can rotate freely, roller between this is to the rail in separate type rail24 are located in the groove 27 that is arranged in adjacent side 14,15,27a and can be two sides in the time that sunshade stretches out or retractsTo in any direction on moving along trough roller. Alternatively, roller 24 can be formed as the sliding part sliding along groove 27,27a.

Separate type rail 20,22 is expressed cross section for circular, but is not to be necessary for circle. Separate type rail is also represented asIn the rail of the upper and lower of every tracking, there is the rail of same diameter, but this can change :-for windy position, Ke NengxiHope the upper rail as every tracking with larger rail, to strengthen the resistance of sunshade to ascending air.

Flexible material 16 is not fixed to mid-rail 22, and can between two of an each rail part, slide, as belowMiddle description.

End rail 20 and mid-rail 22 link together by the jockey that is two rope 25,26 forms, two ropesIn-orbit, extend, adjacent with each longitudinal edge of flexible material. Each rope 25,26 can be single continuous rope(as shown) can be maybe the multiple parts of separating that are connected to the rope between adjacent rail 20/22,22/22,22/22. SingleIndividual or multiple ropes 25,26 are connected to corresponding arm 23a, are therefore connected to the roller 24 on each side of each rail 20/22. ?Approach rolling-up roll 18 rail 22 each end by a part for rope 25,26 be connected near anchor point 28 rolling-up roll,29. Jockey preferably connects between end in-orbit, as shown in FIG., but also can connect other places of going up in-orbit.

Each end of end rail 20 is connected on the end 13 of framework or near anchor point 30,31 by mobile device,Mobile device is the form of bifilar thick elastic threads 32,33, for example bungee jumping rope (only shown in Fig. 2 and 4), and its length is suchTo make in the retracted position of sunshade, elastic threads is tightened up.

Above-mentioned sunshade operates as follows: the framework 11 of-sunshade is fixed to suitable support member by end 12, to makeSunshade is protruding above by the region of being covered by sunshade. In the time that sunshade is in retracted position, flexible material 16Almost be wound on completely on takers-in 18; Fig. 2 represents to approach the sunshade of complete retracted position, but, for illustrative purposes, do not haveHave completely and retract :-in complete retracted position, separate type rail 22/20 is all positioned near roller 18. In complete retracted position,Elastic threads 32,33 is strained completely, and by mechanical lock (if sunshade is mechanically provided with power) or by rolling-up roll 18CD-ROM drive motor on lock sunshade is remained in retracted position. Should understand, in complete retracted position, flexible material 16Be exposed to dust, rain and sunlight minimumly, and can not collect the ring of the flexible material of water or insect. In addition retract completely,Sunshade be neat and inconspicuous in appearance.

For sunshade is stretched out, remove the lock on rolling-up roll, so that rolling-up roll can be rotated freely; This allows elastic threads32,33 retract, end rail 20 is pulled to end 13, and motion is played with one in the end that hauls flexible material. This motion makes flexible materialMaterial 16 from rolling-up roll 18 around and flexible material 16 stretch out or stretch along the length of framework 11 in the whole length of framework 11Go out to select location. In the time that flexible material 16 has reached stretching out of required degree, can be simple by pinning rolling-up roll 18Sunshade is partly stretched out.

Rail 20 is connected to rail 22 by rope 25,26, so that proper rail 20 is while advancing towards end 13 as mentioned above, and rope25,26 in tow its rail 22 below until rail 22 in the part of the rope 25,26 by between adjacent rail 20/22,22/22,22/22The determined position of length separate along the length of framework 11 till.

The complete extended position of sunshade is as shown in fig. 1 :-rail 22 along the length difference of framework 11 seldom equidistantly everyOpen, to flexible material 16 to provide support to resist ascending air and downdraught.

For sunshade is retracted again, rolling-up roll 18 is rotated so that flexible material 16 is wound on around roller 18. This willEnd rail 20 pulls back towards the end 12 of framework 11, and flexible material 16 slides straight between the multipair rail that forms mid-rail 22Till end rail 20 contacts adjacent rail 22 and pushes this rail to end 12. When flexible material 16 is wound on rolling-up roll 18 graduallyWhen upper, each mid-rail 22 be pushed to retracted position successively until rail 20,22 be all positioned at be adjacent to each other, near rolling-up roll 18Till position. This motion is by elastic threads 32,33 tensions.

In retracted position, rope 25,26 is suspended between adjacent rail with the form of ring, but because rope is thin, soThey can not collect water or insect in any perceptible degree, and they are not ugly yet. As described above sunshade is lockedIn retracted position.

The second embodiment of the present invention has been shown in Fig. 5-8. The principal character of this embodiment be when sunshade inIn retraction/deposit position time, the jockey between end rail and mid-rail does not hang down below sunshade, but unobvious statusOn the upper surface of sunshade.

Sunshade framework 11 and rolling-up roll 18 be with described identical with reference to figure 1-4, and use in the accompanying drawings same attachedFigure mark. End rail 40 and mid-rail 41 are formed separate type rail, as described in reference to figure 1-4, but are that rectangular cross section is (with the aid of pictures8) and by groove 27,27a in the side 14,15 of sliding part instead of roller engage frame; Sliding part is arranged in low frictionOn the (not shown) of polyester mesh surface, slide.

As the preceding embodiment, flexible material 16 is not fixed to mid-rail 41, but two parts of track itBetween be free to slide.

Jockey 42 is the form of lightweight rope, and it comprises elastic part. With particular reference to Fig. 7 and 8, each centreRail 41 and end rail 40 are equipped with two anchor points that separate 43, respectively have one near two ends in-orbit. Each mid-rail 41 is also joinedHave two porose retainers 44 that separate. Each anchor point 43 and each retainer 44 are the top from corresponding rail simplyThe pin that stretches out of upper surface, the longitudinal axis of pin is substantially perpendicular to the longitudinal axis of rail.

With reference to figure 7a and 7b, each jockey 42 comprises the first elastic part 42a, and it at one end has ring 45 and separatelyOne end has block 46; In use, ring 45 engages with one of anchor log 43. In Fig. 7 a and b, for clear, a companyConnection device is represented as dotted line.

The Part II 42b of each jockey 42 is inelastic ropes, and it is connected to elastic portion at block 46 placesDivide 42a, pass the aperture in adjacent retainer 44 and anchor to one of anchor point 43 on adjacent rail.

In each mid-rail 41, the first elastic part 42a of each jockey 42 is from one of anchor point 43 along railUpper surface extend to away from the retainer 44 of anchor point 43 that is fixed wtih this first elastic part 42a, then Part II42b is at the anchor point 43 extending to above the upper surface of fabric 16 on adjacent rail 41, this anchor point be fixed wtih above-mentioned partThe anchor point 43 of 42a is relative diagonally, so 42 one-tenth zigzags of each jockey are across the upper surface of sunshade.

Specifically, with reference to figure 5, sunshade shown in this Fig has three mid-rail 41a, 41b, 41c, is fixed to the first railJockey 42c on anchor point 43a on 41a left side extends to the retainer 44a away from anchor point 43a along this rail,Then extend downwardly on next rail 41b, with anchor point 43a relative anchor point 43b diagonally. Rail 41a also hasTwo jockey 42d, its second anchor point 43c from rail 41a extends to retainer 44b along this rail, then to downward-extensionTo with anchor point 43c relative anchor point 43d diagonally.

On the second rail 41b, anchor point 43b and 43d jockey 42f, the 42e other with two engages, jockey42f, 42e are connected in an identical manner to anchor point 43e and the 43f on the 3rd rail 41c. Sunshade shown in Fig. 5 is shorter,Only there are three mid-rail; Thereby jockey 42g, the 42h of the 3rd mid-rail 41c are connected to the anchor point on end rail 4043g、43h。

Said apparatus operates as follows :-for sunshade is stretched out, remove the lock on rolling-up roll 18, allow elastic threads 32,33Retract and end rail 40 is pulled to the end 13 of framework, as above-mentioned the first embodiment.

End rail 40 is connected to adjacent mid-rail 41c by jockey 42g and 42h. When end rail 40 is along the length of frameworkWhen degree is advanced downwards, the elastic part of jockey extends to allow that end rail 40 moves away from adjacent mid-rail 41c, until oneTill individual point, the block 46 on this some place jockey contacts with corresponding retainer 44 and prevents that jockey is furtherExtend. Then, it pulls on this group jockey extending between mid-rail 41b and mid-rail 41c, and mid-rail 41b is movedMove the position shown in Fig. 1, at this point, corresponding block 46 contacts the retainer 44 being associated, to pull and centreThe jockey that rail 41a is associated.

L shaped restricted arm 50 prevents that the first mid-rail 41a is moved beyond the position of selecting in advance, and restricted arm 50 is requiredThe end position of mid-rail 41a is respectively fixed to the both sides of sunshade framework. Each restricted arm 50 is at the upper surface of mid-rail 41Top is interval, to make to hold the anchor point 43 in whole mid-rail on rail and except the first mid-rail 41a can beRestricted arm below by. Anchor point 43a, 43c on the first mid-rail 41a are higher than other anchor points, thereby contact restricted arm 50,As shown in Figure 8.

Sunshade fabric 16 is only fixed to rolling-up roll 18 and end rail 40 certainly, and in the time that sunshade stretches out in mid-railTwo parts between simply slide.

For sunshade is retracted into deposit position, make rolling-up roll 18 rotate that flexible material 16 is wound on to roller 18 weeksEnclose. This will end rail 40 retract towards the end 12 of framework, and flexible material 16 between the part of mid-rail 41, slide untilTill end rail 40 contacts adjacent rail 41c and pushes this rail to end 12. When flexible material 16 is wound on rolling-up roll 18 graduallyTime, each mid-rail 41c, 41b, 41a are pushed to retracted position successively, until all the position of mid-rail closer to each other, with volumeRise roller 18 adjacent till. In the time that mid-rail is pushed away together, the elastic part of each jockey 42 shrinks, by jockeyElastic part is withdrawn into the position shown in Fig. 6. In this position, the contraction of elastic part absorbs appointing in each jockeyWhat is lax, thus jockey do not hang down between rail, the sunshade of giving retraction outward appearance in good order.

Fig. 9 shows the 3rd preferred embodiment of the present invention, and its middle-end rail 50 and mid-rail 51a, 51b are by the company of rigidityConnection device is connected to each other. Fig. 9 shows a side of sunshade; Relative side is the mirror image of first side. Conventionally, connectConnection device is arranged to there is one group of jockey near each end in-orbit, as described below. But, for narrow sunshade, canNear the midline of sunshade or center line, use independent one group of jockey.

As shown in Figure 9, adjacent rail 51a/51b, 51b/50 connects by rigid rod 52,53, and this rigid rod is by fixingThe block 54,55,56,57 that arrives the upper surface of rail supports. Bar 52 is fixed between block 54 and 55, and bar 53 is fixed on bulkBetween part 56 and 57. It is upper that each bar 52,53 is respectively fixed to one of block 54,56, but can slide through respectively another pieceShape part 55,57.

In the time that the sunshade of retracting is reaching the position shown in Fig. 9, (described by reference to embodiment 1 and 2Or with reference to the described mobile device of Figure 10), end rail 50 move in the direction of arrow A and bar 53 to slide through block 57 straightTill the end stop 58 on bar 53 contacts the sides adjacent of block 57, so further fortune in the direction of arrow AMove and draw mid-rail 51b along equidirectional. In the time that the end stop 59 on bar 52 contacts the adjacently situated surfaces of corresponding block 55,Bar 52 draws again mid-rail 51a in the direction of arrow A, this continuation until sunshade stretch out completely.

That that approaches most rolling-up roll 18 stretches out highlyer than other block to block 54 from the surface of mid-rail, soThey contact retainer 54a and guarantee that mid-rail 51a is correctly positioned. All the other block are enough little of under retainer 54aFace passes through.

In the time that sunshade is retracted, as two other embodiment, the fabric wrapping of sunshade 16, will around roller 18End rail 50 pulls to roller 18. As other embodiment, fabric 16 slides between the part of mid-rail. When end rail 50 is towards phaseWhen adjacent mid-rail 51b moves, bar 53 slides through block 57 until end rail 50 contacts mid-rail 51b, and start byThis rail is pushed roller 18 to. Then, bar 52 slides through block 55 until mid-rail 51b contact mid-rail 51a.

That the mechanism of the 3rd embodiment provides between is in-orbit very firm, effectively connect, and is comparison but shortcoming is itHeavy structure and when sunshade is retracted its outward appearance so likablely because even in retracted position, bar 52,53 existsOn the top of sunshade, be also obviously visible.

Above-mentioned whole three embodiment have used the mobile device (being elastic threads 32,33) of describing with reference to figure 1-4.

Figure 10 illustrates alternative preferred mobile device :-this mobile device can with above-mentioned three embodiment inAny uses together.
