Abstract

The utility model discloses an umbrella. The umbrella comprises a supported awning which is unfolded and retained on a rack providing no other point; a pocket (9) positioned at the periphery of the awning (3) and a strength transmitting component (8) positioned in the awning are arranged at the top ends of ribs (6 and 7). When the umbrella is propped up, the strength transmitting component is opened so as to provide a surface which props outward so as to form an area load between the pocket and the awning. The transmission of the component (8) is realized through the radial outward movement of a slidable outer pipe (7) of which the inner end is connected with the shaft (2) of the umbrella. The inner rod (6) and the outer pipe (7) form the ribs or the spokes of the umbrella, which are supported and lifted through a first supporting rod (11) connected between the ribs and a first shaft slide block (12). The utility model overcomes the disadvantages in the traditional design; and when the umbrella is used, the ends of the ribs do not exposed outside and are positioned in the horizontal position of human eyes, so as to avoid dangers.. When being used under a strong wind and the frame has a tendency of turning inward, the integral structure is good, and the awning can not be separated form the frame.

Description

Umbrella

Technical field

The present invention relates to a kind of umbrella, specially refer to a kind of opening and closing mechanism of umbrella.

Background technology

Umbrella can be used for to the user keeps the sun off, wind and rain and being easy to carry, and perhaps can be designed to be fixed on the bottom surface (bigger radius than portable umbrella being arranged as parasols).

Basically, the basic design of umbrella does not have any variation in 3rd century in the past.Traditional pack is drawn together an axle, and its end connects an awning, and the other end connects a handle.A collar structure is used for supporting awning, when umbrella during at unused state, makes the axle collar and awning receive and arrives to a compact more state, the collection of like this being more convenient for.

Collar structure comprises that some ribs (normally 8 ribs) distribute radially along axle equably, and their the inner is articulated in the awning end of axle.The excircle of awning is connected to the outer end (simply hitching by line usually) of each rib.The end of every rib all exposes usually, and has a stopper or other blunt shape things.In a lot of umbrellas, be fixed on a position for the supporting elevation rib and them, each root rib provides a support along rib length that articulates with its end points, and its other end is pivotally attached on the slide block that slides along axle.When umbrella during in user mode, slide block can lock near the awning end at axle.

For the convenience of the users, above-mentioned umbrella design there are some little improvement.Improvement comprises, push-button automatic deployment mechanism comprises a spring usually, and it is used for stored energy when the umbrella contraction state, is used for a slide block to slide vertically and unfurl an umbrella.Another relevant nearest improvement provides a kind of folded umbrella and is used for adapting to and is placed in handbag or the document envelope.Such umbrella generally includes the axle of a multistage, and continuous section all is to be fit to slide block slide.Support the size that rib reduces umbrella by the awning that uses multistage.The support rib pivotally links together and is folded into " V " or " W " type.

The shortcoming of above-mentioned traditional design (with its little improvement) is, when umbrella during in user mode, the rib end is exposed to the outside, and is positioned at roughly pedestrian's horizontal eye position, can compare danger like this.Equally, in high wind, when frame had the tendency of inwardly turning over, awning may will separate with frame, can cause the infringement that can't repair to umbrella frame or awning usually.

We notice also that if not all traditional design canopy material can predetermined tension.This is because when support had the umbrella of traditional frame design, the pressure at right angle of user on the axle slide block converted the pressure on support bar to, gradually vertical pressure converted to along the radial outside awning pressure of awning radius.Along with the approaching softened state fully of awning, support bar (support rib) is near level, and in opening the awning process, the user only needs sub-fraction strength (support force of vertical member) and do not need very big strength (support force of horizontal part).Be easy to observe, when packing up traditional umbrella,, hinder the axle slide block movement and when slide block slides into end points, become an accelerator although the speed that the angle between axle and the rib changes is reducing.Therefore, in traditional umbrella design, tension force is that rib does not then need of great use in awning.

If yunna spiraea or umbrella stand can be got back to original position easily, be very necessary, also be an advantage.

The specific embodiment

About the present invention describes and other technology contents, characteristics and effect, in the detailed description of a first-selected embodiment in following cooperation with reference to the accompanying drawings, can clearly present.

Consult Fig. 1 and Fig. 2, disclose a kind of according to umbrella 1 of the present invention.Umbrella 1 comprises a umbrella stand, and umbrella stand has an axle 2, or contiguous or awning 3 is arranged near a section of axle, and handgrip 4 is at the other end of axle.Axle 2 can be solid also can be hollow and can be columniform or optional cross-sectional type as square, hexagon or octagonal.Umbrella stand comprises that the awning of the awning end of an axle 2 extends and Folding device, and their structure will be described below.

As clearly shown in Figure 2, or be provided with flange or a packing ring 5 of a circle near axle 2 awning end.Packing ring 5 to the direction of axle fix and not slidably estimation on axle 2.Some ribs or spoke 6 pivotally connect and radial being arranged on the packing ring 5.Though packing ring 5 has above six roots of sensation rib, the structural capacity (will confirm in explanation) owing to increasing by structure of the present invention is provided with the umbrella to big golf type, need be more than 6

ribs

6,7.

Each root rib comprises an interior bar 6 that extends between packing ring 5 and a strength transmission device or the diffusing power device 8 (cannot see, but can relate in Fig. 5 E at Fig. 5 A) in Fig. 1 and Fig. 2.The strength transmission device is hidden in the pocket, as when the pocket 9 of smooth propagation, the perhaps corresponding rib of compartment is located at the periphery of the bottom of awning 3.Each pocket 9 has an opening to make strength transmission device 8 insert and move, but the edge of pocket 9 comes along the periphery of awning 3 to provide a lifting-line or surface for each strength transmission device contact at least.Pocket openings is in the face of the mid portion of awning, and such strength transmission device can be arranged in the pocket.Such as, opening can form as slit in pocket, and it is to allow (close or compression) transmission device 8 to insert that slit is connected to a

rib

6,7 and size fully.

Selectively, pocket 9 can be substituted by an independent pocket, and it extends in the whole periphery of awning.A pocket like this can be simply form around the periphery of awning by stitching a strip (as, several centimetres wide).

In each root bar 6 can by an independent bar make or can comprise (as two) contiguous but independently bar interconnects, end-to-end.By this way, but bar has special physical characteristic (as being relatively fixed property) can form near one section of the interior bar of axle as the steel pole of 2mm diameter abaxial section of bar in can lighter more soft interior bar material (as glass fibre) can forming in one first, and the power of bearing in abaxial place can be smaller so can be reduced weight.Two of interior bar 6 or multistage more, such as, can be the same length.

An outer tube 7 can slide along interior bar 6 at the end away from axle 2.Interior bar 6 should have identical shape of cross section to use outer tube 7 to slide along interior bar 6 with outer tube 7.Better, but interior bar 6 and outer tube 7 are circular cross section other shapes, also can be used as square, hexagon or octagon.Interior bar 6 and outer tube 7 are preferably coaxial.

Each root outer tube 7 provides a connector 10, and it can be to be made of the carbonic acid polyester, and receives the outer end of one first support bar 11 rotationally.Connector 10 preferably be positioned at or around every outer tube 7 from axle one segment distance, the length of the length of distance and first support bar is identical or a little shorter.Such as, can be placed on from the place of rib axle head 21cm if the length of each root first support bar approximately is 26cm then connector 10, on the outer tube 7 (when umbrella at its low or folding fully state).Though the inner of each root outer tube 7 can be consistent with the position of connector 10, outer tube extends inwardly past the length that connector 10 reduces the interior bar 6 that exposes can be better.Will explain in detail that as the back expose portion of interior bar 6 is connected to awning 3 and acts on the side of the umbrella of support, above umbrella, the curve of the awning of a visible interruption between outer tube 7 and interior bar 6.The inner of outer tube 7 can have the inner that end cap (as shown in the figure) is used for propping up outer tube 7, catches it when awning canvas slides.End cap requires a mesopore to make interior bar pass through.

The inner of each root first support bar 11 (near axle 2) connects near an anchor ring 22C first slide block 12 rotationally by a connector, and first slide block 12 can slide along axle 2.Moving up and down on the axle of first slide block 12 (no matter manual still automatic umbrella of spring) caused umbrella to strut accordingly and folding.The axle protrusion 26 of habitual locking mechanism such as load on spring can be installed in and make slide block 12 be retained in a position on the axle, and umbrella is just locked when strutting like this.We can see that first slide block comprises part 12A and higher columniform compartment 12B of a lower columniform attraction user, and their importance will be explained below.

In order to improve the flexibility that unfurls an umbrella, one second support bar 13 is connected between the mid point and one second slide block 14 (Fig. 1 or Fig. 2 are unmarked) of first support bar 11, and second slide block slides between the packing ring 5 of axle 2 and first slide block 12.Connection between second support bar 13 and first support bar 11 makes that relevant rotation is arranged between them.In the embodiment shown, a connecting ring or manage 15 and can constitute by carbonic acid polyester, polypropylene or macromolecule polypropylene, it is fixed to first the only about half of of support bar 11 and (is more suitable for, about 15/26) position of length, and the outer end of second support bar 13 intersection pivotally is connected to connecting ring 15 by nail.Connection between second support bar 13 and second slide block 14 makes corresponding rotation between them.

Each root second support bar 13 can be the cross-sectional type of U type or common projection, when umbrella makes during at folded state first support bar, the 11 adjustment positions that link to each other with it minimize the volume of folding stand.Cutting out section can when at folded state, be used for adjusting connector 10 in second support bar.In the process that unfurls an umbrella, second support bar 13 and second slide block 14 have reduced user's effect, but they are not indispensable in its operation.

Bias unit such as spring 23 can be arranged near the axle 2, between the packing ring 5 and second slide block 14.Spring 23 helps operation to avoid pushing away to such an extent that too far overrun to first slide block 12 in the process that unfurls an umbrella, and still also can help to avoid any released movement (that is to say that in the slide block movement process, spring can effectively continue any " loose ") of slide block.The spring constant of spring 23 is not that requirement is very big, particularly must compress at the heavy spring of the process that unfurls an umbrella, and the user does not need to compress spring with too much strength.

Packing ring 5, first slide block 12 and second slide block 14 can all manually be made by the plastic material of rigidity, as polypropylene, high polypropylene or carbonic acid polyester.Axle 2, first support bar 11, interior bar 6 and outer tube 7 can be made by the metal of glass fibre or folding/roll.Be more suitable for, interior bar 6 (to the outer tube than the zonule) can manually be made by flexible material pliable and tough or that easily stretch and make the awning support present shaped form.As previously mentioned, interior bar 6 can comprise an inside such as a steel pole that toughness is smaller.Second support bar 13 can be formed by rigid plastic material or folding steel.

Awning 3 can be made of any traditional wind, rain, sunshade fiber, as canvas or nylon.So the size of awning can arrange from the centre of awning the distance of the highest distance position of 9 in each pocket to equal from the axle to the transmission device distance of 8 outmost point completely.

5A at first with the aid of pictures can see that to 5E each transmission device 8 comprises first leg 16 and second leg 17 that pivotally is connected a fulcrum district 22.At the folded state of the umbrella shown in Fig. 5 A,

leg

16 and 17 constitutes continuous " V " type.The outer end of outer tube 7 in bond (as, adhesive or screw) 18 li of an installation shaft of pipe, the leg 19 of intersection and 20 flexibilities extend to their end from pipe installation shaft 18, end pivotally is connected to and moves back 16 and 17 accordingly.Pipe installation shaft 18 comprises an intermediate conduit, and the outer end by bar 6 in this intermediate conduit can be passed through before brake 21 is prevented, and is that the end of center-aisle connects or be integrally formed in the fulcrum district 22 that leg 16 and leg 17 are seen.Brake 21 forms the parts of an elongation, has a central longitudinal hole, and is suitable dimensionally in the end of interior bar 6.The end of interior bar 6 slides in brake 21.

Transmission device 8 can integral body be formed at plastics, and as the randomcopolymer polypropylene, each all has the hinge of pivotally connected (between fulcrum 22 and

leg

16,17 and

leg

16,17 and leg 19,20) formation activity.

Because the outer end of bar 6 in the outer end of outer tube 7 slides into along interior bar 6, we can see to Fig. 5 E is heavy at Fig. 5 A, when outer tube 7 extends to the end and pipe installation shaft 18 when touching brake 21, leg 16 and leg 17 open or launches to form a very straight line or and T-shape of pipe 7 formation in Fig. 5 E.The other radiation campaign of outer tube 7 will outwards be moved whole transmission device corresponding to interior pipe 6, though the fully extended state of frame coincidence tube installation shaft 18 first contact brakes 21 more.Especially, when awning is tight from 9 lira in pocket, leg 16 and leg 17 will bend to arc or continuous " U " type because pocket is making of projection can use awning reposefully from the strength of the tension of transmission device 8 around.As previously mentioned, interior bar 6 slides in brake 21, and can see for allow brake keep in bar and for as Fig. 5 A to the propagation action generation of 5E, strength must get radial fulcrum district 22 and this strength of inwardly being carried in by carrying on the awning pocket 9 or contact-making surface provides.

At the umbrella shown in Fig. 3 A, 4A and Fig. 6 A is at fully folding state,

rib

6,7 lie low against or adjacent shafts 2, awning 3 for increase transparency and transmission device 8 legs 16 and leg 17 in continuous " v " type of a closure.

In Fig. 3 B, 4B and 6B, first slide block 12 has been moved upwards up to about mid point along axle 2.We can see that

rib

6,7 turns to away from axle 2 by first support bar.Second slide block 14 still keeps identical distance, but is pushed to end packing ring 5 by second support bar 13.When the folded state shown in contrast Fig. 3 A and Fig. 4 A, the leg 16 and the leg 17 of transmission device 8 have been opened a little a bit.

Like this, spring 23 is by slight compression, and the motion that makes progress for second slide block 14 provides identical resistance.Ideally, the resistance that provides can stop the motion that slide block 14 makes progress completely temporarily.But as previously mentioned, spring 23 big spring constants can make the user increase strength.Therefore, in an embodiment of the umbrella that Fig. 7 A will be described below to Fig. 7 D, the position at the device place that is used for guaranteeing that second slide block 14 stops temporarily showing in Fig. 3 B, 4B and 6B.

In Fig. 3 C, 4C and 6C, second slide block 14 be in as Fig. 3 B, 4B and 6B in the same along the position at axle place.First slide block 12 still move up towards its top and

rib

6,7 still from axle 2 to inner rotary.Yet the inner of second support bar 13 is fixed on the position (because second slide block, 14 temporary fixed ground) such second support bar 13 now fully and rotatablely moves with regard to the inner that is defined around it.The outer end of second support bar 13 can cause the lever of first they sup-port on these balance pivots as any further moving upward that the fulcrum of lever is connected to such first slide block 12 of mid point of first support bar.As a result, a kind of mechanical advantage produced one in the outer end of first support bar 11 the radial strength that continues along rib.This lasting strength acts on the outer tube 7 by connector 10.We can see that also the

leg

16,17 of transmission device 8 among Fig. 3 and Fig. 6 is open bigger than the leg among Fig. 3 B and Fig. 6 B.

In Fig. 3 D, 4D and Fig. 6 D, we can see first slide block 12 axle 2 moved up some shift to the end packing ring 5, second slide block 14 is also without any moving of making progress, rib 6 from axle 2 to inner rotary some and outer tube 7 has further left or along them corresponding in bar 6 slided, away from axle 2.We can see that also in fact the

leg

16,17 of transmission device 8 has opened fully, so the awning (not shown) will be owing to straining along the radial strength that acts on outer tube 7.We also can notice, this radial strength will be from the awning periphery (through be formed at the seam of 9 li in each pocket along the awning periphery) along line or load surface transmission by the leg 16 and the leg 17 of transmission device 8, rather than resemble traditional umbrella at a point.

In Fig. 3 E, 4E and 6E, we can see that second slide block 14 has further moved up and spring 23 further has been compressed on axle 2.This is the state that umbrella stand fully struts, and first slide block 12 has arrived and moved the final position of second slide block 14 to it.Umbrella stand can be supported or be locked in abundant open position by a traditional load on spring axle protrusion 24, and it can be removed in axle, makes passing through of the slide block 12 of winning in commonly known mode.The downward motion that protrusion 24 is provided as first slide block then provides one to stop up to being depressed by the user.

Second slide block 14 that 12 top columniform compartment 12B of first slide block is used for pushing away upwards and also fix the rearmost position of first slide block and second slide block.We can see that second slide block can be positioned at the centre position of first slide block and end packing ring 5.Abundant softened state as shown in Fig. 4 E, we will be noted that second support bar 13 fully with

rib

6,7 side by side and axle,

first support bar

11 and 13 formation of second support bar or near an equilateral angle.We can find that final structure is very firm.

In the position that fully struts, any other strength that makes progress is loaded into first slide block 12 and is converted into the pulling force that hides tent, because transmission device 8 attempts radially outwards to move, attempts to increase the length of the rib of umbrella.Same, any other strength as a gust of wind, acts on below the awning, and awning is difficult to upset (perhaps outwards blowing from the inside), needs 11 rotations of first support bar or upwards, this action meeting second support bar 13 has stopped because will overturn.Therefore periphery at awning 3 is fixed radially, increases the dynamics of umbrella structure and has increased the anti-rain of some canopy material.Further because

rib

6,7 compacted they seldom may be to distorting on one side, distortion is that the structure upset is needed.

With reference now to Fig. 7 A to Fig. 7 D (notice structure Fig. 6 A in the 6E as seen), among the embodiment of structure, will describe second slide block 14 temporarily be obstructed make progress move.We cause the crooked of rib and have increased friction by the interior bar 6 of outer tube 7 second slide block of also can finding temporarily to be obstructed.Such as, the position that rests on distance end packing ring 5 about 10cm that second slide block 14 can be interim.

At Fig. 7 A in 7D, only an independent support bar 11 and second an independent support bar 13 as seen, such first slide block 12 and second slide block 14 comprise some holes, these holes are generally occupied by the end of other support bars.Fig. 7 A is corresponding to Fig. 3 A, 4A and 6A, and umbrella stand is by fully folding in the drawings.Can see that a clip 24 extends from second slide block, 14 ground lower surfaces downwards.Clip 24 preferably is made of elastomeric material, and as the firm bar of elasticity, and inwardly biasing is pointed to axle 2 so that a hook part 25 touches axle ground outer surface.Hook part 25 is C types fully, though its overground part almost is flat and is bent downwardly therefrom and protruding part.

Fig. 7 B corresponding to Fig. 3 B corresponding to Fig. 3 B and 3C, Fig. 4 B and 4C and Fig. 6 B and 6C.In Fig. 7 B, the hook part 25 of clip 24 axially go up to move and know and enter slit 27.Owing to directly be biased on the clip 24 in inside, hook is pulled to slit 27, and going up of hook put down the top edge that part touches slit.The moving of second slide block 14 (second support bar 13 has applied vertical member from their strength that is connected to first support bar 11 and first support bar 12 and moved up).

Fig. 7 C is corresponding to Fig. 3 D, 4D and 6D, and the top columniform interval of first slide block 12 touches the hook part 25 of clip 24 and by the curve part of cam effect along downward sensing hook, takes out hook portion 25 from slit 27.Therefore, second slide block 14 freely moves up on axle again.In case hook is removed, outer tube 7 in agley bar or other friction pulling force money of outer tube ground will be radially in its ground bar shift.

Fig. 7 D is corresponding to Fig. 3 E, 4E and 6E, in picture, umbrella is fully supported open and top cylindrical ground at interval 12B fully in clip 24 slip underneath and bear (moving upward) second slide block 14.

In umbrella ground folding process, hook part 25 (outstanding forward, above the axle of clip) moves along the surface of axle and this enters slit 27 again, but is not stuck, because the end of hook can be given prominence to the outside at slit.The lower surface camber of hook part touches the lower limb of slit then and continues to lower slider from continuation along axle.

Load on spring axle protrusion 24 also is of great use in the process of folded umbrella, and it has stopped 14 downward the moving of second slide block, recalls the rib of outside along interior bar 6.Like this, the flat portions of the top edge of protrusion 26 is parallel with the lower surface of second slide block 14.Make second slide block 14 against protrusion 26 like this, any parts that are not applied to the strength on the protrusion can start the direction of recalling of protrusion (the unable axle that directly points to just).Relative, the lower surface of protrusion 26 preferably curved surface or flexure type make second slide block 12 in the process that umbrella supports by protrusion, thereby it is retracted in the axle 12.

As previously mentioned, awning 3 at first touches umbrella stand by the effect of transmission device 8, and transmission device 8 is positioned at the pocket 9 of pre-layout, and pocket is in the position of arranging along the same intervals that hides the tent periphery.In addition, awning can be fixed to axle 2 end (as packing ring 5) and be connected to

rib

6,7 at the identical point along their length, by, as be that the mode of (not shown), seam is connected to the awning the inside, awning can be or be connected to each root rib.A preferred connected system can merge VELCRO release to be fastened, and the circle and the hook that are included in corresponding opposite make awning be moved easily, are very easily.Therefore, the user can replace or select the awning that conveniently makes land used special in an orderly manner, according to umbrella stand of the present invention can be fit to easily or not needs user tool using just can remove.

We it will be appreciated that the present invention can use axle umbrella or fixed axis umbrella that use that umbrella, parasols or beach umbrella and sunshade and the present invention can be same can fold.We can notice that also various aspects of the present invention can merge to other umbrella class devices, and back shaft or arm are a general mid point such as the collapsible rope of cloth rotatably, tent or the awnings of being connected to radially.In the collapsible rope of cloth rotatably, do not need to merge feature such as transmission device end at each root rib.

The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
