Description

cantilever umbrella

technical field

The utility model relates to a cantilever umbrella for providing sunshade protection.

Background technique

EP2103230 discloses a typical cantilever umbrella. The rod supports a cantilever arrangement extending laterally from the rod. The cantilever arrangement in turn supports the canopy that provides shade from the sun. The umbrella can be changed from, for example, a folded configuration for storage, in which the outrigger is close to the pole and the canopy is folded, to an in-use configuration, in which the outrigger has been laterally removed from the pole out and the canopy has been deployed. This is carried out using a crank mechanism with a lever, during operation of which gears engage with a rack along the rod to deploy the cantilever, and the rope connected to the canopy mechanism is spooled for deployment on the spool of the awning.

Utility model content

The technical problem to be solved by the utility model is to provide a cantilever umbrella that is easier to use and simpler to manufacture.

To this end, a cantilever umbrella is provided, which includes a rod, a sliding member, a cantilever device, and an awning mechanism. The sliding member can slide along the rod. The boom arrangement is supported by the rod and includes a boom and a strut. The cantilever pivots at the sliding member. The strut pivots at the rod at the first end and pivots at the cantilever at the second end. The canopy mechanism is supported by and freely suspended from the cantilever device and can be actuated by pulling a cord extending at least on a path between the sliding member and the canopy mechanism to the canopy mechanism.

wherein the cantilever means can be extended by sliding the slide member such that sliding of the slide member simultaneously causes the cantilever means to extend further laterally away from the rod and actuation of the canopy mechanism, the cord extends along the rod on a portion of the path at a first point and The distance between a second point, the first point being on or adjacent to the rod, the second point being movable with the sliding member such that sliding the sliding member along the rod in a predetermined direction increases the distance, thereby extending the path , resulting in the pulling action of the rope on the awning mechanism.

In particular, the cantilever umbrella includes a rod along which a sliding member such as a handle can slide. The rod supports the cantilever arrangement, which in turn supports the awning mechanism for folding or unfolding the awning. The canopy mechanism is actuable, ie can be manipulated, by pulling the cord. The rope runs on a path that is the route the rope takes to reach the canopy mechanism. The overall path can be conceptually divided into sub-paths, which thus form part of the path. Such a first sub-path extends between the sliding member and the awning mechanism and may extend along the awning and/or the awning arrangement. Furthermore, the rope extends along the rod on a second sub-path of said path a distance between a first point on or adjacent to the rod and a second point which can be moved together with the sliding member . With this arrangement, when the sliding member slides along the rod in a predetermined direction, the distance between the first point and the second point increases, extending the second sub-path of the rope along the rod, thereby also increasing the second The length of the total path of the rope to which the subpath belongs. This results in a pulling action on the awning mechanism.

The point on or adjacent to the rod may for example be the point at which the rope is fixed to the rod, but also the point at which the rope goes around the pulley on its way to the fixed point. The point and/or said second sub-path of the rope may eg be inside the pole, but also along the outside of the pole or along a track adjacent to the pole.

This arrangement allows a considerable simplification of the mechanism for operating the canopy mechanism, since no crank mechanism is required. For example, the rope may be extended along the rod on the second sub-path to the sliding member, and on the first sub-path, by securing the rope at a point on or adjacent to the rod, for example by means of one or more pulleys This is accomplished with a path extending from the sliding member away from the rod and towards the canopy mechanism. As mentioned above, when the sliding member is pushed in a direction away from the fixed point and thus towards the canopy mechanism as seen along the rope, the length of the overall path of the rope increases.

Alternatively, the cord may be fixed to the sliding member, extend along the rod on the second sub-path to the pulley and possibly through one or more additional pulleys to the canopy mechanism. In this case, the second sub-path of the cord is extended when the sliding member is pushed in a direction away from the canopy mechanism as seen along the cord.

Preferably, the first sub-path from the rod and/or sliding member to the canopy mechanism has a constant length. This has the effect that a given elongation of the path of the rope as described above translates into an equivalent pull on the canopy mechanism.

The boom arrangement may be extended by sliding the sliding member such that sliding of the sliding member simultaneously results in extension of the boom arrangement and actuation of the canopy mechanism. The term "extendable" should be understood herein as having a mechanism that allows the boom device to extend further laterally away from the rod when the mechanism is actuated. This allows simple operation of the cantilever umbrella.

The boom arrangement may include: a boom pivoting at the sliding member; and a strut pivoting at the rod at a first end and pivoting at the boom at a second end. In that case, upward movement of the sliding member causes upward movement of the first end of the cantilever arm, which in turn causes the second end of the cantilever arm to move downward due to pivoting towards the strut, thereby causing the cantilever device to move due to The cantilever and the canopy supported by the cantilever extend further laterally from the pole. With this configuration, the sliding member and cord will be arranged such that the predetermined direction - in which sliding of the sliding member causes a pulling action on the canopy mechanism - will be upwards.

The canopy mechanism may be freely suspended from the cantilever arrangement, ie connected to the cantilever arrangement at a single point. Thus, components of the canopy mechanism, such as ribs and struts, are structurally separate from the cantilever arrangement. This allows easy assembly.

The cantilever umbrella may further comprise a first pulling member, such as a first pedal, for pulling a cord that actuates the canopy mechanism, wherein the cord is attached to the first pulling member. This is useful to allow final tensioning of the rope after sliding the sliding member along the rod as described above.

The cantilever umbrella may also include an auxiliary member biased to exert a force on the sliding member for assisting sliding of the sliding member. The auxiliary member may for example take the form of a weight or a spring, such as a compression spring or an extension spring. Preferably, the spring is a constant force spring. This has the effect of reducing the force that needs to be applied by the user to the sliding member when operating the canopy mechanism, working against the force of gravity on the canopy to deploy the canopy. This makes the umbrella easier to operate.

When a counterweight is used, the second rope may preferably extend between the counterweight and the sliding member through a first pulley, preferably at the top end of the rod. The counterweight can be located in the cavity of the rod, which saves space.

The cantilever umbrella may also further comprise a second pulling member, preferably a second pedal, which is coupled to the sliding member such that, preferably at an initial stage of sliding of the sliding member, in contact with the sliding member for deploying the canopy and/or The sliding of the sliding member is caused by driving the second pulling member in the opposite direction of the sliding that extends the boom device. The boom arrangement may have a geometry in which the force required to extend the boom arrangement has a maximum value at the beginning of the sliding movement of the sliding member. In the exemplary configuration with the cantilever and strut mentioned above, this is due to the small effective lever arm between the sliding member and the pivot point between the cantilever and the strut. In this case, it may be helpful to use a pulling member such as a pedal, which makes the cantilever umbrella easier to handle. This can be achieved by a third cord attached at the second pulling member and at the sliding member, the third cord preferably extending between the second pulling member and the sliding member through a second pulley, preferably the second pulley The ground is at the top of the rod.

Preferably, the function of the second pulling member can be combined with the function of the first pulling member such that the second pulling member is identical to the first pulling member, ie identical to the first pulling member. This saves space and simplifies the cantilever umbrella, making it easier to manufacture.

Furthermore, the first pulley and the second pulley may be arranged such that they have a common axis. This also saves space.

The awning mechanism may include: a plurality of awning ribs; a plurality of awning stays; and a movable member, wherein each awning stay of the plurality of awning stays is connected to the plurality of awning ribs and pivots at the movable member, and wherein a cable is attached to the movable member such that pulling of the cable through the plurality of awning struts actuates the plurality of awning ribs, wherein, The movable member includes one or more stops that prevent at least one awning strut of the plurality of awning struts from becoming at the point of attachment to the movable member parallel to the pull direction of the rope.

Without the stop, the awning struts would generally be parallel or nearly parallel to the pull direction of the cords when the awning mechanism is fully folded, and the awning ribs would in turn be parallel or nearly parallel to the awning struts. This makes the deployment of the canopy difficult, since the effective lever arm for deploying the canopy by actuating the canopy ribs via the canopy struts is small. The presence of the stop prevents the canopy mechanism from assuming this problematic position when fully folded, thereby making it easier to deploy the canopy mechanism.

The movable member may include a plurality of recesses at the outer periphery of the movable member, each recess of the plurality of recesses having a limiting surface, wherein each of the plurality of awning struts Pivoting at a limiting surface of a corresponding one of the plurality of recesses. One or more of the confinement surfaces of the plurality of recesses may have protrusions that form one or more stops.

In certain embodiments, the one or more stops are configured to stop any of the plurality of struts other than the two or more awning struts pivoting at opposite sides of the movable member All awning stays outside. This allows for efficient packaging and transport of the awning mechanism. Alternatively, the one or more stops are configured to stop all of the plurality of awning stays.

According to a second aspect, there is provided a cantilever umbrella comprising: a rod; a pulling mechanism arranged at the rod for pulling a rope; a cantilever arrangement supported by the rod; and an awning mechanism, The canopy mechanism is supported by a cantilever arrangement and can be actuated by pulling a cord extending at least on a path between the pulling mechanism and the canopy mechanism to the canopy mechanism, wherein the canopy mechanism includes a plurality of awnings a canopy rib; a plurality of canopy stays; and a movable member, wherein each canopy stay of the plurality of canopy stays is connected to a corresponding canopy rib of the plurality of canopy ribs and is movable between pivoting at the member, and wherein the tether is attached to the movable member such that pulling of the tether actuates the plurality of canopy ribs through the plurality of awning struts, wherein the movable member includes one or more stops, The one or more stops prevent at least one awning stay of the plurality of awning stays from becoming parallel to the pull direction of the cord at the point of attachment to the movable member.

Without the stop, the awning struts would generally be parallel or nearly parallel to the pull direction of the cords when the awning mechanism is fully folded, and the awning ribs would in turn be parallel or nearly parallel to the awning struts. This makes the deployment of the canopy difficult, since the effective lever arm for deploying the canopy by actuating the canopy ribs via the canopy struts is small. The presence of the stop prevents the canopy mechanism from assuming this problematic position when fully folded, thereby making it easier to deploy the canopy mechanism.

The movable member may include a plurality of recesses at the outer periphery of the movable member, each recess of the plurality of recesses having a limiting surface, wherein each of the plurality of awning struts Pivoting at a limiting surface of a corresponding one of the plurality of recesses. One or more of the confinement surfaces of the plurality of recesses may have protrusions that form one or more stops.

In certain embodiments, the one or more stops are configured to stop the plurality of struts other than two or more awning struts pivoting at opposite sides of the movable member of all awning stays. This allows for efficient packaging and transport of the awning mechanism. Alternatively, one or more stops are configured to stop all awning stays of the plurality of awning stays.

Detailed ways

FIG. 1 is a perspective view of the cantilever umbrella 2 according to the first embodiment as viewed obliquely from above. The cantilever umbrella 2 includes a rod 4 , a cantilever device 8 and a canopy mechanism 10 .

The rod 4 has the basic shape of a hollow cylinder. When the cantilever umbrella 2 is in use, typically the pole 4 will be supported by a bracket, frame, base plate or the like (not shown) connected to the ground.

The rod 4 has a sliding member in the form of a handle 6 which can slide along the rod 4, as indicated by arrow A.

In the depicted embodiment, the handle 6 has a cylindrical shape surrounding the outside of the rod 4 . In other embodiments, the sliding member 6 may eg be positioned to the side of the rod 4 so as to possibly slide along the track or may be positioned partially inside the rod 4 .

A cord 26 (not visible, see Figures 2a, 2b and 4a) is attached to the tread 22, extending along the column 4 to the sliding member 6 and along the cantilever 14 to the canopy 10. This will be described in more detail below.

The pedal 22 can be used as a pulling member on the rope, as will be described further below in connection with Figure 2c. The pedal 22 can slide along the rod 4, as indicated by arrow B. There is a pedal stop 24 in the form of a collar surrounding the rod 4 . The pedal stop 24 prevents the pedal 22 from sliding upward beyond the pedal stop 24 . The tension in the ropes 26 from the weight of the canopy mechanism 8 will pull the pedals up against the pedal stops 24 .

The boom arrangement 8 is supported by the rod 4 and comprises a boom 14 and a strut comprising two rigid rods 12 . The cantilever 14 pivots at the first end at the pivot point P ₁ at the sliding member 6 . The bar 12 of the strut pivots at the pivot point P ₂ at the top end of the rod 4 and at the midpoint P ₃ of the cantilever 14 . Thus, sliding the sliding member 6 upwards along the rod 4 causes the pivot point P1 to move upwards, and thus the _first end 7 of the cantilever 14 also moves upwards, causing the second end 9 of the cantilever 14 to move downwards. Hence, this results in the extension of the cantilever mechanism.

The canopy mechanism 10 is supported by the cantilever 14 at a pivot point P4 adjacent to the second end 9 of the cantilever ₁₄ . The canopy mechanism 10 includes eight obliquely downwardly directed ribs 16 arranged symmetrically around a circle centered at a point at the top end of the shaft ₂₀ positioned below and adjacent to the pivot point P4 at pivot point P ₄ . Ribs 16 pivot at points located on the circle. In normal use, the ribs 16 will be covered by a canvas (not shown) that provides shade from the sun. The eight stretches 18 pivot at the lower end of the shaft 20 and extend obliquely upwards to respective pivot points located along the respective rib 16 , eg along the midpoint of the respective rib 16 . The pivot point at the lower end of the shaft is connected to the cord 26 (see Figures 2a, 2b and 4a) so that pulling the cord creates an upward force on the stretcher 18 which in turn raises the rib 16 so that Unfold the canopy. In Figure 1 the canopy is shown in a fully deployed position. The canopy mechanism 10 can be actuated, ie can be manipulated, by pulling on a cord (not shown), as will be described in more detail below.

Figure 2a is a perspective view from the side showing the cantilever umbrella 2 according to the same first embodiment as above in a folded configuration suitable for eg storage. The sliding member 6 is located at the lower position A ₁ along the rod 4 . With regard to the boom arrangement 8, the struts 12 and the boom 14 are located in a nearly vertical position. The user operating the cantilever umbrella 2 can now begin to slide the slide member ₆ upwards from the lower position A1, as indicated by the arrow, causing the cantilever device 10 to extend as described above, as indicated by the dashed arrow. At the same time, the upward sliding of the sliding member causes a pulling action on the cord 26, resulting in the unfolding, ie raising, of the canopy. The lower end of the awning mechanism is in the lower position _C1 . The vertical distance between this lower end and the pivot point P ₄ is denoted D ₁ . The pedal 22 is located in an upper position B ₁ adjacent to the pedal stop 24 and is held in this position by the tension of the rope 26 .

Figure 2b is a perspective view from the side of the cantilever umbrella 2 according to the same first embodiment as above, during the extension of the cantilever device 8 and the actuation of the canopy mechanism 10. _The sliding member is located at the intermediate position A2. As the user continues to slide the sliding member 6 along the rod 4 as indicated by the arrow, the boom arrangement 8 continues to extend as shown by the first dashed arrow and at the same time the canopy mechanism 10 continues to pass through the sliding member 6 is actuated by a pulling action on the rope 26 caused by the sliding of the , as indicated by the second dashed arrow. The lower end of the canopy mechanism is located at the intermediate position _C2 . The pedal ₂₂ remains in the upper position B1.

Figure 2c is a perspective view from the side of the cantilever umbrella according to the same first embodiment during the extension of the cantilever device 8 and the later stages of the actuation of the canopy mechanism 10 . The sliding member ₆ has now reached the upper position A3. Optionally, a locking device (not shown) can be used to lock the sliding member 6 in place in this position. The lower end _of the canopy is located at position C3. _In this position, the vertical distance between the lower end of the canopy and the pivot point P4 is _denoted D2. Thus, the distance that the lower end _of the canopy has moved relative to pivot point P4 is D1 _- D2 ₍ for D1, see Figure 2a ₎ compared to position _C1 . Since the path of the rope 26 along the boom 14 is constant, ie independent of the configuration of the boom 14 when the boom arrangement 8 is extended, this distance D ₁ -D ₂ is equal to the distance D ₃ traveled by the sliding member 6 .

To achieve the final tensioning of the rope 26, the pedal 22 can be driven as indicated by the arrow in Fig. 2c. This results in a further pull of the cord 26 on the canopy mechanism, actuating the canopy mechanism as shown by the dashed arrow in Figure 2c.

Finally, Figure 2d shows a perspective view from the side of the cantilever umbrella according to the same first embodiment, with the cantilever device 8 fully extended and the canopy 10 fully deployed. _The pedal ₂₂ has moved down the distance D4 to the lower position B2. For the same geometric reasons as before, this distance is equal to the distance D5 _traveled by the lower end of the canopy between position C3 ₍ see Figure 2c) and position _C4 .

Figure 3a is a perspective view from the side of the cantilever umbrella 2 according to the second embodiment, the cantilever umbrella 2 being shown in a folded position. This embodiment is configured such that the deployment of the canopy 10 and the extension of the boom arrangement 8 are preferably initiated by actuating the pedals 22 . This second embodiment is the same as the first embodiment, except that the pedal 22 is coupled to the sliding member 6 such that when the pedal is actuated, moving the pedal downward from position B1 as shown by the arrow, the sliding member ₆ is as shown by the dashed line Move upward from the initial position A1 _of the slide member 6 as shown by the arrow. The boom arrangement 8 and the canopy mechanism 10 are then driven according to the same principles as described above with respect to the first embodiment, moving as indicated by the dashed arrows. The coupling between the pedal 22 and the sliding member 6 will be described in further detail below in conjunction with Figure 4a. In the folded configuration of the cantilever device depicted, the effective lever arm between the sliding member 6 and the pivot point _P3 between the cantilever and the strut is small, requiring a relatively large force for sliding through The member 6 is slid to initiate the extension of the cantilever device 8 . The coupling between the pedal 22 and the sliding member 6 provides this force by actuating the pedal 22, thereby making the umbrella 2 easier to operate.

Figure 3b is a perspective view from the side of a cantilever umbrella according to the same second embodiment as in Figure 3a, showing a later stage of the extension of the cantilever device and the actuation of the canopy mechanism. The pedal 22 has been brought down to the lower position B ₁ where the pedal 22 can be locked by a locking device such as a pin (not shown). Further operation of the boom arrangement and the canopy arrangement into the fully extended and deployed positions (see Figures 2a-2d) is carried out by the user actuating the sliding member 6 in the same manner as already described in relation to the first embodiment.

Figure 4a is a cross-sectional view of a cantilever umbrella according to the first or second embodiment, showing the arrangement of ropes and weights, and a perspective view of the pulley arrangement.

According to the first or second embodiment, the first cord 26 is attached to the pedal 22 at point P ₁ and at the rod 4 along the path P ₁ -P ₂ -30-32-34 to the canopy mechanism 10 The interior of the trundle extends along the rod 4 a distance d ₁₂ to a point P ₂ on the pulley 28 of the sliding member ₆ , where the first rope 26 is guided onto the cantilever 14 by the pulley 28 and the further pulley 30 . The rope 26 is guided onto the canopy mechanism 10 by two additional pulleys 32 , 34 after extending along the cantilever 14 . Pulling the sliding member 6 upwards, ie in the direction towards the canopy mechanism 10 as seen along the rope 26 increases the distance _d12 , thereby extending the overall path _of the rope between point P1 and the canopy mechanism P ₁ -P ₂ -30-32-34, resulting in a pulling action on the cord 26 at the canopy mechanism 10 .

Likewise, according to the first or second embodiment, an optional second cord 36 is attached to the sliding member 6 , extending along the rod 4 inside the rod 4 to a first pulley 38 located near the top of the rod 4 , at the first pulley 38 the second rope 36 reverses direction and extends down to the counterweight 40 , ie the second rope 36 goes around the first pulley 38 and extends to the counterweight 40 . Therefore, the upward pulling of the sliding member 6 is assisted by the gravitational pull on the counterweight 40 , which is thus biased to serve as an auxiliary member for assisting the sliding of the sliding member 6 . This can fully or partially compensate for the weight of the canopy when it is unfolded. The counterweight 40 is located inside the rod 4 , in the cavity of the rod 4 . Alternatively, the weights may be replaced by springs, such as compression or extension springs, positioned eg adjacent to the sliding member 6 .

Optionally, according to the second embodiment, a third rope 42 is attached to the sliding member 6 , extending along the rod 4 inside the rod 4 up to a second pulley 39 which preferably has a common connection with the first pulley 38 axis, which saves space. The rope 42 reverses direction at the second pulley 39 and then extends down the rod 4 inside the rod 4 to the pedal 22 to which the rope 42 is attached. This couples the pedal 22 to the sliding member such that driving the pedal 22 acting as a pulling member downward causes the sliding member 6 to slide upward. In the depicted embodiment, this pedal 22 is identical to the pedal previously described above. However, the two pedals can also be separate.

FIG. 4b is a cross-sectional view of a cantilever umbrella according to the third embodiment, showing an alternative arrangement of the first rope 44 and optional weight 40 . Here, the rope is attached to the sliding member 6 at point P4 and extends a distance d along the rod 4 inside the rod 4 on the path P ₄ -P ₃ -48-50-32-34 to the canopy mechanism 10 ₃₄ Up to point P ₃ on the pulley 46 near the lower end of the rod 4 , the rope reverses direction at point P ₃ so as to extend inside the rod 4 along the rod 4 through the sliding member 6 without contacting the sliding member 6 . Engaged until pulley 48 which guides the rope towards the canopy mechanism 10 onto the canopy mechanism 10 or along the strut 12 via pulley 50 to both pulleys 32, 34 along the outer part of the cantilever 14, The pulleys 32, 34 guide the rope 44 onto the canopy mechanism in the same manner as in the previous embodiment. Pulling the sliding member 6 upwards, ie in a direction away from the canopy mechanism ₁₀ as seen along the rope increases the distance _d12 , thereby extending the total path P4 of the rope between point P4 and the canopy mechanism _- P ₃ -48-50-32-34, resulting in a pulling action on the rope.

An optional counterweight 40 is attached along the rope 44 at a point between the lower pulley 46 and the upper pulley 48 on the rope. As in the previous embodiment, the weight 40 may optionally be replaced by a spring, eg a spring positioned adjacent to the sliding member 6 .

Essentially, the process described here for extending the cantilever device and/or deploying the canopy is reversible and can be performed in reverse order to bring the cantilever umbrella 2 from the extended and deployed configuration back to the folded configuration .

FIG. 5 shows a cantilever umbrella with a particularly advantageous arrangement for the canopy mechanism 10 . All the features and alternatives described above in connection with Figures 1 to 4b apply to this cantilever umbrella. As in Figure 1, the canopy mechanism is supported by the cantilever mechanism 8 at a pivot point adjacent the distal end of the cantilever. The canopy mechanism comprises six obliquely downwardly directed ribs 16 arranged symmetrically around a circle centered at a point at the top end of a shaft 20 positioned below the pivot point and adjacent to the pivot point. Ribs 16 pivot at points located on the circle. In normal use, the ribs 16 will be covered by a canvas (not shown) that provides shade from the sun. The six extensions 18 pivot at the disk-shaped movable member 502 and extend obliquely upward to respective pivot points located along the respective rib 16 , eg along the midpoint of the respective rib 16 . A cord 26 (not shown, see Figures 1, 2a, 2b and 4a) is attached to the movable member 502 such that pulling the cord creates an upward force on the stretcher 18 which in turn raises the rib 16 , thereby unfolding the canopy. Here, the canopy is shown in a fully deployed position. The canopy mechanism can be actuated, ie can be manipulated, by pulling on a cord (not shown, see Figures 1, 2a, 2b and 4a), which has been described in detail above.

Accordingly, the canopy mechanism includes a plurality of canopy ribs 16, a plurality of canopies 18, and a movable member 502, wherein each canopy strut 18 of the plurality of canopy struts 18 is connected to the plurality of canopies 18 A corresponding one of the canopy ribs 16 and pivots at the movable member 502 and wherein the cord 26 (not shown, see FIGS. 1 , 2a , 2b and 4a ) is attached to the movable member 502 , so that pulling of the cords 26 (not shown, see FIGS. 1 , 2a , 2b and 4a ) actuates the plurality of canopy ribs 16 through the plurality of canopy stays 18 .

The movable member 502 includes a plurality of recesses 504 at its outer periphery. Each recess 504 is U-shaped and has a limiting surface that includes an inner wall and two side walls. Each canopy stay 18 pivots at the side wall of the corresponding recess 504 .

Four of the six recesses 504 have protrusions 506 extending radially outward from the inner wall. These protrusions 506 act as stops so that the corresponding awning strut 18 is stopped by the protrusions 506 when pivoting upwards so that the awning strut 18 cannot reach parallel to the axis 20 and to the cords 26 (not shown) The pull direction is parallel to the configuration.

Accordingly, the movable member 502 includes one or more stops 506 that prevent at least one of the plurality of awning struts 18 from reaching the movable member The attachment point of 502 becomes parallel to the pull direction of cord 26 (not shown). One or more of the limiting surfaces of the plurality of recesses 504 have protrusions 506 that form one or more stops 506 .

2a, when the awning mechanism 8 is in the folded position, the awning struts 18 are approximately parallel to the pull direction of the cords 26, and the awning ribs 16 are in turn parallel or approximately parallel to the awning stays 18. In this configuration, the lever arm for deploying the awning mechanism 14 by actuating the awning ribs 16 through the awning struts 18 is small, requiring a large pulling force on the cord 26 . The presence of the stop 506 prevents the canopy mechanism 14 from assuming this problematic position when fully folded, thereby making the canopy mechanism 14 easier to deploy.

To achieve this effect, it is not required that all canopy stays 18 have corresponding stops 506. In the particular embodiment of FIG. 5 , four of the six recesses 504 are provided with stops 506 . The two recesses 504 without the stopper 506 are positioned opposite each other across the movable member 502 . This allows for efficient packaging and transport of the awning mechanism. Alternatively, all six of the recesses 504 may have stops 506 .

This arrangement of the movable member 502 described with reference to Figure 5 would also be useful for cantilever umbrellas that operate with a crank mechanism, such as those mentioned in the background section.

The inventive concept has been mainly described above with reference to a few embodiments. However, as is readily understood by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the inventive concept as defined by the appended claims.

For example, the cantilever arrangement may be fixed such that only the canopy mechanism is actuated when the sliding member is slid.

Various alternatives have been disclosed above for extending the cords 26 , 44 between the rod 4 and the canopy mechanism 10 in order to actuate the canopy mechanism 10 . Other options are possible, for example the cords 26 of the first and second embodiments extend directly diagonally between the sliding member 6 and the top of the canopy mechanism 10.

The pole may not necessarily be vertical, but may also stand at an angle.
