Describe in detail
Below by description various device or method to provide the example of the embodiment of each claimed invention.Following embodiment does not limit any claimed invention, and any claimed invention can cover the following device that do not describe or method.Claimed invention is not limited to the characteristic device of institute or the method with following any one device or method, is also not limited to device or the method for the multiple or all total feature had in following apparatus.Following apparatus or method are not likely the embodiments of any claimed invention.Applicant, inventor and the owner to retain disclosed in following apparatus or method all authority of any invention of failed call protection in this document, and can not abandon, waive the right or contribute any invention like this to the public by its in this document open.
First with reference to Fig. 1-4 of accompanying drawing, which show first embodiment of the present invention.This first embodiment is designated as mark 10, and shows the support 40 comprising the umbrella frame 12 that eight equal intervals are opened.The quantity of umbrella frame can change, and such as, and umbrella 10 can have ten, 12,14,16,18,20 or more umbrella frames, comprises odd number umbrella frame; Also can imagine that umbrella 10 can have and be less than eight umbrella frames.As detailed below, parachute kit of the present invention has outside umbrella frame element, is straight, but bends in closedown configuration and become bending at closedown configuration peripheral umbrella frame element; Therefore, closing the effective radius of umbrella frame in configuration or length with opening in configuration adds compared with its length.The quantity of umbrella frame is less, and this effect is more obvious.
First embodiment of Fig. 1-4 is umbrellas 10 of the umbrella frame 12 in addition with constant length.First embodiment provides umbrella frame 12 that is variable or adjustable length, to regulate this effect of the effective radius of change outer umbrella frame element.Following second embodiment about Figure 12 A-12E provides folding or contractile umbrella rib structure.Recognized when such umbrella support is folded or shrink, provided lax in canopy inherently, it can be used for effective increase of the length adapting to umbrella frame 12.
Although it should also be understood that the umbrella that the invention describes and use for individual, it is applicable to the umbrella of any type, sunshade, cover from sun or similar canopy.The present invention is applicable to the umbrella of any size, comprises beach umbrella, golf umbrella, courtyard umbrella etc.In addition, the present invention is applicable to the asymmetric umbrella of the umbrella frame with different length.Such as disclosed in the PCT application WO2006/132525 announced.
Each umbrella frame 12 has by the inside umbrella frame element 14 that is slidably connected and middle part umbrella frame element 16.As shown in the figure, inner umbrella frame element 14 can be bar, and middle part umbrella frame element 16 can be pipe.Preferably can put upside down this to arrange, inner umbrella frame element 14 is configured to pipe, and middle part umbrella frame element 16 is configured to bar.Other suitable slip any can be used to arrange.
Middle part umbrella frame element 16 is connected with pair of outer umbrella frame element 18.As detailed below, the outer end of each umbrella frame element 16 is connected with the outer end of the umbrella frame element of contiguous umbrella frame 12, or be connected with the canopy 20 of umbrella term (umbrella term), to maintain the outer end of the umbrella frame element of close or close contiguous umbrella frame 12.In some embodiments, can be that interval separates in the end of the outside umbrella frame element 18 opening in configuration contiguous umbrella frame 12.As detailed below, many kinds can be provided to arrange to the outer end of outside umbrella frame element 18.
Each umbrella frame 12 has the first supporting umbrella bone (primary support rib) the 22, first supporting umbrella bone 22 and is connected pivotly with umbrella frame element 16 in the middle part of it at 24 places, and is connected with the first slider 26.Second supporting umbrella bone 28 is connected with the first supporting umbrella bone 22 pivotly at 30 places, and is connected with the second slider 32.
In a known manner, retaining mechanism can be provided for support umbrella support in the position of hope, usually represent to mark 38.Such mechanism can comprise the spring-loaded protrusion stretched out by the groove in main shaft 42.
Fig. 1 and 2 shows umbrella 10 in the configuration being in and usually opening and support 40 thereof.Referring now to Fig. 3 A-3D and Fig. 4 A-4E, which show the support 40 opened progressively along with umbrella.
In figure 3 a, show the support 40 of closed position, umbrella frame 12 is close to main shaft 42.As shown in the figure, outside umbrella frame element 12 is substantially parallel to each other to downward-extension.Such effect is to give total effective radius, represented by 44 to umbrella frame 12.Open umbrella term to impel, user catches handle 46 bottom main shaft 42 and the first slider 26.In a known manner, first user may must discharge Lock Part or brake apparatus, and this Lock Part or brake apparatus are used for detention first slider 26 and therefore make support 40 usually be in closing in configuration.
As shown in Figure 3 B, along with the first slider 26 is along axle 42 upward displacement, umbrella frame 12 is outwards shifted.Side by side, the first supporting umbrella bone 22 and being outwards shifted with the connecting portion 24 of middle part umbrella frame element 16.Successively, the connecting portion 30 of the second supporting umbrella bone 28 radially outwards displacement and away from main shaft 42.Therefore, although the second slider 32 is along main shaft 42 upward displacement, the first and second sliders 26,32 are movably closer to each other.
The function that 34, spring stops the second slider 32 to move up.Guarantee not need too large power to open umbrella 10, may wish to give spring 34 low spring constant.Connecting portion 30 has been impelled outwards to be shifted by the opposing of spring 34 to mobile second slider 32.Successively, this causes middle part umbrella frame element 16 to slide along inner umbrella frame element 14, and trend stretches the length of umbrella frame 12.
May wish to guarantee to reach or close to this sliding motion that Central element 16 occurs before opening configuration at support 40.Open configuration along with support 40 reaches, umbrella frame 12 is bending, and this may make the sliding motion between inside and middle part umbrella frame element 14,16 more difficult and stand more frictions.Therefore, can preferably guarantee to buckle at umbrella frame 12 and pressurizeed by canopy 20 before there are the whole or most of of this sliding motion.But for this reason, as in the PCT application WO2005/048765 announced to describe in detail, may be provided in the mechanism of the motion of certain some place's stopping second slider 32, so that the continuation campaign of the first slider 26 causes middle part umbrella frame element 16 radially outward to slide into maximum extend of hope.Then further motion release second slider 32 of the first slider 26, to allow two slider elements 26,32 all to reach to be shown in Fig. 3 D final opens configuration.For this reason, the first slider 26 has lower collar 26a and upper collar 26b.Lower collar 26a is used for being held by user, and upper collar 26b adjoins the second slider 32 to produce the effect of above detailed description.
Fig. 3 D shows the support 40 of fully open position.Canopy 20 represents with profile 50.It has effective radius 52, illustrates equally, the effective radius represented with 44 that the umbrella frame 12 being less than closed position has in this effective radius 52, Fig. 3 A with 52.
Fig. 4 A-4E also show the effect of the umbrella frame length of change.As shown in Fig. 4 A and 4D, when the beginning of opening umbrella, middle part umbrella frame element 16 only has small stretching, extension along umbrella frame element 14, as with represented by 56.It is only greater than in Fig. 4 C slightly with the initial separation represented by 58.When umbrella is all opened, middle part umbrella frame element 16 slides further along inner umbrella frame element 14, to the spacing given represented by 60.As mentioned above, the straight configuration shown from Fig. 3 A and 4C along with outside umbrella frame element 18 be bent to show in such as Fig. 3 D and 4E open configuration completely, select spacing to regulate effective change of radius.
Effective change of described radius will depend on many factors, comprise the quantity of umbrella frame 12 and the characteristic of outside umbrella frame element 18.As detailed below, outside umbrella frame element 18 can have many different sections (profile) or cross section.And outside umbrella frame element 18 can have the cross section along its length variations, to give different flexural properties at difference place.Simple analysis supposes: open a pair vicinity in configuration and the outside umbrella frame element 18 be connected is formed and a part for the circumference of middle part umbrella frame element 16 tangent, in fact just over semicircle; Only in two dimension, carry out described analysis further, and ignore the more complicated three-dimensional doxne shape of umbrella.According to described analysis, the difference (weighing with the percentage opening radius in configuration) opening and closing radius between configuration is: for 8 umbrella frames for 22.8%; Be 18.6% for 10 umbrella frames; Be 14.9% for 12 umbrella frames, and will be less for umbrella frame such as 14,16,18 or 20 umbrella frames of larger quantity.
Get the approx. dimension of the 76cm (30 inches) of golf umbrella and the conventional umbrella radius of 57cm (221/2 inch) that is compact-folded or contractile umbrella, we can calculate the numerical value of radius change.For golf umbrella, value is: be 17.3cm for 8 umbrella frames; Be 14.1cm for 10 umbrella frames; And be 11.3cm for 12 umbrella frames.For compact-folded umbrella, value is: be 13cm for 8 umbrella frames; Be 10.6cm for 10 umbrella frames; And be 8.5cm for 12 umbrella frames.Although the mechanism be shown in Fig. 1-4 is schematic diagram, it should be understood that the value that the relative scale alterable of different elements represents to give more than golf umbrella; It should also be understood that this General Principle is applicable to otherwise fix any umbrella of overall umbrella frame.As detailed below, for folding or contractile umbrella can the size of selection mechanism so that it regulates the change of radius inherently.
Referring now to Fig. 5-9, which show the modification of outside umbrella frame element 18, distinguishing mutually by using suffix a, b etc. at this.
Fig. 5 A shows the middle part umbrella frame element 16 formed with pipe, and middle part umbrella frame element 16 engages the inside umbrella frame element 14 be only partially shown with the form of bar slidably.As mentioned above, optionally by putting upside down pipe with the layout of bar or by other suitable slide construction any, middle part umbrella frame element 16 can slide in inner umbrella frame element 14.Fig. 5 A and 5B shows the outside umbrella frame element 18a with rectangular cross section.In a known manner, second moment of area or resistance to bending and width proportional, and be the cube of the degree of depth.Therefore, if the degree of depth is three times of width, so, as shown in Figure 5 C, about the second moment of area of axis 62 than about large nine times of the second moment of area of axis 64.Arrow 66,68 schematically represents the comparatively macrobending amount of deflection existed about different axis for same load or moment of flexure.
The section of umbrella frame element 18 can be selected to give flexural property and the intensity of hope.In order to resist wind load, can give outside umbrella frame element 18 the significant degree of depth (think that canopy 20 is not simple plane surface, but the three-dimensional bending of complexity being surperficial) in the direction with canopy 20 less perpendicular.This is shown in Fig. 5.Side by side, in order to allow outside umbrella frame element 18 bend and open support 40, and without the need to the power that user overuses, can be made into relatively narrow at the outside umbrella frame element 18 of the horizontal direction of Fig. 5 C, to give lower resistance to bending, the section of Fig. 5 C shows these characteristics.
And outside umbrella frame element 18 can not have constant cross section.Such as, variable cross-section is to change about one or two the second moment of area shown in Fig. 5 C in axis or resistance to bending.May wish to maintain high and constant resistance to bending about axis 62, to resist wind load, change resistance to bending about axis 64 simultaneously, to guarantee that outside umbrella frame element 18 adopts the profile of wishing.
Such as, horizontal width (in Fig. 5 C horizontal size) can be gradually reduced to less size in its outer end, so that outer end portion is more pliable and tougher from the large scale of the inner at each outside umbrella frame element 18.The degree of depth can keep constant or also can similarly reduce gradually to outer end from the inner.Available fishing rod carries out analogy, is usually tapered from handle to the end of bar.Even if it should be understood that the degree of depth keeps constant, width diminishes gradually will affect two second moment of area; But about the second moment of area (affecting the amount of deflection in arrow 66 direction) of axis 64 by more influenced than other second moment of area about axis 62.
Fig. 6 A and 6B shows the section of the selectable circle of outside umbrella frame element 18b.At this, in order to give the flexural property changed, the diameter of cross section can be change.In addition, in order to change flexural property about different axis, cross section in the different some change along umbrella frame element 18b, and can be different from circle.
Fig. 7 A and 7B shows the cross section of the ellipse of outside umbrella frame element 18c.In addition, the size of this cross section of alterable is to give the flexural property of wishing along the length of outside umbrella frame element 18.The major axis of alterable oval cross section and the relative size of minor axis, to change the flexural property about different axis independently.
Fig. 8 A and 8B shows the foursquare cross section of outside umbrella frame element 18.In addition, can along this section of length variations of outside umbrella frame element 18, to give the characteristic of wishing.
Fig. 9 A and 9B shows modification, wherein as the outside umbrella frame element 18a in Fig. 5 C has the different second moment of area about two axis.At this, outside umbrella frame element 18a is fixed on middle part umbrella frame element 16, so that its axis 88 relative to each other tilts at an angle.As shown in Figure 9 A, axis 88 and horizontal plane are at an angle.This is for controlling the shape of canopy 20.As shown in fig. 9d, when canopy 20 is seen at the top that generally along canopy, when namely directly seeing the edge of canopy, there is shallow V-shaped.Shown in 70a, join with shallow angle in the outer end 70 of outside umbrella frame element 18.If regulate two area moments about axis 62,64, so that umbrella frame element relatively easily can bend in response to the side crops industry in arrow 66 direction, but be hard in response to arrow 68 direction, so should obtain being that the direction vertical with canopy has this shape of very small deflection substantially in arrow 68 direction.
Figure 10 shows a connecting portion of hinges 72 form between the outer end 70 of outside umbrella frame element 18.Hinges 72 can be formed with outer end 70 entirety or attach to outer end 70.Hinges 72 comprises opening 74 and attaches to the limit of canopy 20 to allow hinge 72 by sewing.
Figure 11 A and 11B shows pivot or hinge 76, comprises pivot element 78, and this pivot or hinge 76 can be the forms of rivet.As shown in Figure 11 B, the end on this outside umbrella frame element 18 represented with 70b can be shaped to overlap and provide constant thickness at hinge 76 place.By providing the opening 79 through pivot element 78, hinge 76 can attach to the edge of canopy by sewing.Pivot element can be enough firm in transmit bending load between end 70, to maintain their alignment in torsional direction, namely relative to level and the torsional load of axis in Figure 11 B plane, and also can maintain their alignment in response to the bending load about the axis perpendicular to Figure 11 B plane.Pivot connector also can the angular range of opening of confinement end 70 to as shown in Figure 11.
It should also be understood that and various other can be provided to install and be connected layout to the end 70 of outside umbrella frame element 18.Replace contiguous end 70 to be joined together, such as by the sewing in known way, each end 70 can be connected to the edge of canopy 20, and can be spaced.Another selection is in canopy, provide pocket to receive the end 70 of umbrella frame element 18.
As shown in Figure 5 C, outside umbrella frame element 18 can have relatively narrow width, can be freely bending, not need very large strength to open umbrella.But outside umbrella frame element 18 can attach to canopy 20, so that canopy 20 provides structure function and limits the bending of umbrella frame element 18.How Fig. 5 D can attach to canopy 20 at each place represented with 80 if showing umbrella frame element 18.As indicated by arrow 82, if radial load puts on umbrella frame element 18 joint, then it trends towards impelling umbrella frame element 18 bent outward, shown in 84.Due to the connecting portion at 80 places, resist this and moved and a part of canopy 20 represented with 86 between umbrella frame element 18 is tightened up.Therefore, umbrella frame element 18 will seem harder, and can design this integral layout to provide necessary tension force in canopy.
As shown in Figure 5 D, can form canopy 20 with many independent canopy elements 90, described independent canopy element 90 engages along the limit 92 under along umbrella frame 12 and outside umbrella frame element 18.As shown in fig. 5e, can form joint portion to provide microscler groove 94 between canopy element 90, described groove 94 can be continuous print or segmentation, and outside umbrella frame element 18 inserts wherein.Canopy element is sewn to together or otherwise engages at 96 places.This will again make canopy 20 provide structure function and stops the overbending of outside umbrella frame element 18.
In order to the design of outstanding support and umbrella, by different patterns or color application in independent canopy element 90, to emphasize that these are not simple triangular elements, and conventional umbrella can be different from.These canopy elements can comprise center canopy element 90a and edge canopy element 90b, and the latter is represented by its external margin.
Newly design in order to outstanding further the shape given, the canopy element represented with 90b can be omitted, and maybe can replace with less canopy element, and the limit of described less canopy element is arranged to from the main edge of canopy rearward.Example represents with 90c, 90d, 90e and 90f, show different sizes and different borders (it should be understood that, although Fig. 5 D shows many Variant Design, only a kind of design is used to whole umbrella usually, can provide any combination of different designs around umbrella).In this case, at least part of umbrella frame element can be enclosed in the pocket formed by the limit of the canopy element represented with 90b.As mentioned above, the tension force then in canopy element 90a provides extra rigidity effectively by such as impacting in response to the load usually trending towards making canopy upcountry be partial to the main shaft of umbrella on the limit of canopy.
Be omitted entirely at canopy element 90b, represent with 90g, or when canopy element 90b is quite little, so umbrella is rendered as the multi-leaf-shaped outward appearance of class floweriness.
Referring now to Figure 12 A-12C, which show contractile or folding umbrella according to the second embodiment of the present invention.Use similar reference numerals to first embodiment, but add suffix 100 for many marks.Therefore, second embodiment, by marking 110 expressions, has support 140 and comprises main shaft 142, and main shaft 142 is with the umbrella frame 112 of upper end pivotally attaching to axle 142.
By spaced apart first slider 126 and the second slider 132 of spring 128, spring 128 is comparatively hard and for completing opening of umbrella 110.Umbrella frame 112 has the inside umbrella frame element 114 that pivot attaches to the second slider 132.Actuation connection 124 is pivotally connected to the first slider 126 and inner umbrella frame element 114.The comparison of Figure 12 B and Figure 12 C shows along with umbrella 110 to move to the open position of Figure 12 B from closed position (being shown in the part closed position Figure 12 C), and spring 128 can stretch.This stretching, extension orders about umbrella from closed position to open position.
Each inner umbrella frame element 114 is pivotally connected to the first connection umbrella frame 122, and the other end of inner umbrella frame element 114 is pivotally connected to the top of main shaft 142.Middle part umbrella frame element 116 is pivotally connected to respective inside umbrella frame element 114 in isolated position inner with it.As shown in the figure, the inner of each middle part umbrella frame element 116 is pivotally connected to the second connection umbrella frame 130, second and connects the other end of umbrella frame 130 and be pivotally connected to the first connection umbrella frame 122.As first embodiment, each middle part umbrella frame element 116 is connected with pair of outer umbrella frame element 118.Each outside umbrella frame element 118 has with the top of the outside umbrella frame element 118 of contiguous umbrella frame 112 or end is connected or otherwise keep close top or end.The various connection of end and the mounting arrangements of the umbrella frame discussed about Fig. 5-11 are applicable to described second embodiment.
As shown in Figure 12 B and Figure 12 C, spring 128 stretches and orders about slider 126,132 and is separated.Inner umbrella frame element 114 is left behind to the position of the stretching, extension shown in Figure 12 B from the position close to main shaft 142 by actuation connection 124.Along with inner umbrella frame element 114 moves to the position of opening of stretching, extension, inner umbrella frame element 114 makes the end of the first connection umbrella frame 122 move and away from main shaft 142, effectively the second slider 132 be pulled to the top of main shaft 142; In a known manner, the element 144 being connected umbrella frame 122 pivot with first and being connected is there is at the top of main shaft 142.
Along with inner umbrella frame element 114 is connected with first the position that umbrella frame 122 shifts to the stretching, extension in Figure 12 B, second connects umbrella frame 130 makes the outside pivot of outside umbrella frame element 118 and stretches.
The spring 134 with relatively low spring constant is there is between the top and crown member 144 of the second slider 132.Along with the position of stretching, extension moving to Figure 12 B, spring plays the effect of the motion of mitigation second slider.
Normally, the element attaching to umbrella support 140 for the canopy of this contractile or folding umbrella or covering 120 is maintained at the position of hope to help canopy 120 and fitly folds.Therefore, canopy 120 can attach to umbrella frame 112 along multiple positions of middle part and outside umbrella frame element 116 and 118.In addition, connect for each umbrella frame 112 provides with 148 connection chains represented (connecting link) between umbrella frame 122 and canopy 120 first, the line of usual certain length, etc.
