The invention relates to umbrellas and more particularly, to an umbrella having a foldable canopy which is suspended in cantilever fashion from a support post and mechanisms therefor.
Umbrellas are devices which are typically utilised in an outdoor setting, such as in an outdoor patio, balcony, garden, cafe, and the like to provide shade and protection against the elements. Umbrellas generally include a canopy mounted over a plurality of support ribs. The support ribs can be collapsed into a storage position for the canopy assembly and can be deployed and supported in position to hold up and extend the fabric and thereby provides protection from the elements. The canopy is generally supported from beneath or from above. Umbrellas supported from above as typically known as cantilever umbrellas and have the advantage of providing space below the canopy where people can sit without the obstruction of a pole extending from below the canopy to the ground.
However, cantilever umbrellas known in the prior art typically require complex mechanisms to facilitate the deployment, collapse and storage of the canopy. Such mechanisms are typically prone to gathering environmental debris and, over time, becoming seized, damaged and/or unsightly. Further, cantilever umbrellas typically require a certain amount of physical strength from the user to lift and deploy.

Referring now to the drawings, in which like numerals indicate like elements throughout the several views,
The cantilever umbrella 10 generally comprises an upstanding mast 100 pivotally connected to each of an upper cantilever arm 110 and lower cantilever arm 111 which are adapted to support a plurality of upper ribs 112 which in turn support a canopy (not shown). In the exemplary embodiment depicted, the upper cantilever arm 111 is attached to an upper portion of the mast at a pivot point 117, and the lower cantilever arm 110 is pivotally connected between the upper cantilever arm 111 and the mast. Each arm 110, 111 is configured to move between an open position where the canopy is deployed (
A lower hub 300 and upper hub 301 act as support for the pivotal attachment of a plurality of upper ribs 112 which support a canopy and the lower ribs 114 which act to raise and lower the upper ribs.
The pair of cantilever arms extend between the mast at one end and to or toward the lower hub 300 at an opposing end to act to move the hubs 300, 301 away from the mast during a retracted to deployed movement. The cantilever arms act in a scissor type relationship where the relative displacement along the mast where each arm is attached is bought together to cause the retracted to deployed movement.
To facilitate such a movement, the upper cantilever arm 111 is attached at an upper portion of the mast at a first end by a pivotal link 117, and pivotally attached to the lower hub 300 at or toward an opposing end. The lower cantilever arm 110 is operatively associated with the mast at a mast-proximate end, and has a pivotal connection 116 at an opposing end to the upper cantilever arm 111. In this way, vertical movement of the lower cantilever arm 110 about the mast causes movement of the upper cantilever arm.
In particular, raising the vertical position of the lower cantilever arm 110 relative to the mast 100 causes the upper cantilever arm 111 to be raised, and the hubs 300, 301 and ribs, 112, 114 to also be raised such that a canopy supported by the upper ribs is deployed.
The lower cantilever arm 110 may attach to the upper cantilever arm 111 at any point along the arm according to the mechanical ratio desired. For example, attaching the outward end of the lower arm 110 to the outward end of the upper arm 111 would provide the most leverage, but require the most vertical travel up the mast to attain the require deployment extension. In some embodiments, the lower arm 110 is attached to the upper arm 111 midway along the upper arm.
The use of cantilever arms in this manner reduces the effort required to lift and deploy the canopy by providing a mechanical advantage. To further assist with the movement required to deploy the canopy, a biasing device may be provided. In the embodiment depicted, a strut 115 is provided to bias the cantilever arms into the deployed position, thereby providing at least some assistance to the movement to lift and deploy the canopy.
Movement of the carriage is guided by the mast 100. To this end, the mast has an interior region which includes a longitudinally extending channel adapted to support the carriage 120. The channel has an aperture extending from the interior to the exterior of the mast which allows for a point of connection between the carriage and the lower cantilever arm 110 to pass from the mast interior where the carriage is guided, to the exterior where the cantilever arms extend.
A pivotal attachment point between the carriage 120 and the lower cantilever arm 110 is provided by a clevis 121 which has two flanges spaced apart to allow a pivot pin or axle 122 to pass through each flange. The axle 122 supports pivotal attachment with the lower cantilever arm 110 by passing the axle though a hole in lower portion of the arm. As the carriage is raised and lowered, the axle transfers vertical force to the cantilever arm while allowing the arm to pivot relative to the movement of the carriage.
To facilitate carriage travel, the wheels of the carriage and profile of the mast channel 11 are complementary in form. The wheels generally comprise of smaller outer wheels running on the inside face of the extrusion and larger central wheels running down the rear of the mast extrusion cavity. Details in the centre of the large wheels allow the pull rod to run the length of the locking carriage, as well as allowing the wheels to run over the lower lock plate. The carriage also has a linkage bar, hook catch, user handle, release button, pins, spring and fixings as well as the pivot bracket. Moving the carriage actuates the through spar to pivot within the main spar in a scissor like motion and thus reduces the distance between the hubs, deploying the ribs.
Referring again to the extrusion profile shown in
The wheels of the carriage further comprises a second set of wheel surfaces 131 adapted to engage with the inner facing interior surface 14 of the channel 11. Further, the second set of wheels extend from the chassis to engage a surface of the channel that opposes that of the first set of wheels.
In the embodiment depicted, the wheels 131, 132 are arranged to allow the carriage to track up and down the mast to support movement of the lower cantilever arm. It is therefore envisaged that many other forms of carriage support and/or channel details could be employed. For example, there may be wheels arranged diagonally within a recess or corner of the mast such that axial movement of the carriage is facilitated while radial movement is prevented. In other examples, the carriage may wrap around the mast such that radial movement is prevented.
Referring again to
The hook engages with the mast to lock the vertical position of the carriage relative to the mast. The locking catch may also be one or more locking catch details configured to engage in a female slot. Preferably the rod 126 causes operation of the trigger and/or locking catch between an engaged position and a disengaged position. A biasing device 127 is adapted to cause the trigger rest in the engaged position. In some embodiments, the biasing device is a spring orientated to act in compression in response to movement of the trigger from a disengaged position.
To support operation of the locking catch the mast further comprises a receptacle adapted for engagement with the locking catch, such that, raising the carriage within the channel causes alignment of the locking catch with the receptacle. The receptacle may be any form of mechanical engagement suitable for retaining the locking catch such as an actuated catch, a rotational catch, or an aperture formed in the internal wall of the channel. In other embodiments, a carriage support device is removeably attached to the mast and provides the receptacle.
To deploy the cantilever umbrella, the slide carriage is lifted until the locking catch reaches the locking plate. The hook automatically locks the carriage in position by being displaced by the leading edge of the locking catch to compress the biasing device, then releasing when the hook aligns with an aperture 151 and the biasing device releases stored energy. The trigger 124 is at the opposing end of the carriage to the handle to ensure the handle is at the lowest placement when deploying the umbrella, thus making it more accessible to a range of users. In some embodiments, the female slot in the locking plate has an angled profile of 2° or more from horizontal to ensure a safe and secure locking interaction under the weight of the canopy as applied via the lower cantilever arm.
In some embodiments, the carriage locking plate is curved on the top to allow dispersion of rain water away from the slots. In some embodiments, the locking plate and/or the locking catch have a ramped profile to allow the locking catch to slide into place as the carriage is raised without express interaction with the trigger. The ramp puts tension into the locking catch via the biasing device with the stored energy released when the male hook aligns with the female slot. Where a ramp is not used, a user may simply require to hold the trigger down to clear the locking catch.
To release the locking catch from the locking plate, the trigger is pressed in the trigger housing which slides the connecting rod and pivots the locking catch out of the female engagement slot. In some embodiments, the hook has a secondary hook detail which locks the umbrella in the closed position at the bottom of the mast. This acts in a similar manner to the main lock plate but is a slim ramped profile which provides a discreet locking location and for the carriage wheels to travel over the top.
It should be understood that the locking mechanism discussed above may have many other forms. For example, the above described may be replaced with a pin in aperture; or a rotational cam locking arrangement.
In use, the upper lobe of the rocker is aligned with the upper receptacle of the mast, then is pivoted toward the mast such that the lobe engages with the mast to thereby fasten the carriage to the mast at that location where the canopy is deployed. Further, the lower lobe of the rocker is aligned with the lower receptacle of the mast such that the lower lobe engages with the lower receptacle and the carriage is fixed to the mast at that location where the canopy is retracted. In this way, the movement and direction of displacement of the handle can be visually linked to an engaged or disengaged state of the carriage.
According to further embodiments, the umbrella 10 also includes an umbrella mounting assembly adapted to support the upstanding mast 100.
A locking assembly 235 is shown aligned with the vertical member. The locking assembly has an outer form adapted for fitment within the channel 11 of the mast and operates to selectively fix the rotational position of the mast relative to base assembly. In use, the locking assembly is fixed within the mast channel 11 and acts to lock the rotational position of the mast which is otherwise free to rotate about the vertical support 220.
The base plate has a second set of apertures 212 provided to allow for engagement with the locking assembly 235. The locking assembly allows rotation of the mast 100 about the support member 220 when in an unlocked configuration, and locks the mast to the base plate then in a locked configuration. The locking assembly 235 thereby allows selective fixation of the mast rotation about the support member 220.
Referring to
To cause movement of the pin, the latching mechanism is supported by the housing and has components including a lever arm 240 pivotally connected to the housing at one end. The lever is connected to a rod 253 which causes displacement of the pin 250 as the lever is raised and lowered. In some embodiments, a biasing device 251, such as a spring, is provided to cause displacement of the pin into the engaged position when the lever is not being lifted. In this way, the mast may be rotated around the base plate and the pin will be automatically engaged with one of the base plate apertures 212 when alignment occurs.
The lever arm is preferably secured within the housing of the locking mechanism and mast when not in use. A releasable catch may be employed to provide the desired position of the catch.
The housing 230 is of a form adapted to be received the second longitudinally extending channel of the mast. In this way, the housing is able to be fixed inside the outer profile of the mast to thereby avoid any components which protrude from the mast. The lever arm is of a form such that it may extend through the aperture of the second longitudinally extending channel to be accessed externally. In this way, the lever may be moved on the exterior of the mast, while the pin is moved on the inside of the mast.
The housing 230 of the locking assembly 235 is fixed to the mast extrusion interior by any conventional means of attachment. In the embodiment depicted, a fastener 232 extends through the housing and mast interior wall to fix these components together.
It is desirable for the mast to be secured to the base plate so that gusts of wind do not lift or destabilise the umbrella. To secure the mast and locking assembly to the vertical support of the base, yet allow rotation of the mast about the vertical support, the vertical support has a circumferential groove 221 in the outer surface thereof at a location vertically displaced from the base plate—observable in
According to further embodiments, the umbrella 10 also includes the hubs 300, 301 which locate the many ribs 112, 114 that support the canopy. The hubs act as a central location from which a selection of ribs will span. The ribs are connected to the hub by a pivot device such as a pin in slot. However, there are a variety of embodiments that differ in the number of ribs desired to support a canopy. For example, in some embodiments, a square or octagonal canopy form is desired, necessitating the ribs to radiate from the hub with a separation angle of 45 degrees. In other embodiments, a rectangular canopy form is desired, necessitating the ribs to radiate from the hub at 45 and a different separation angle according to the desired layout of spars to support a desired canopy form. Particular angles at which ribs extend from the hub will be necessary in some circumstances to support a desired canopy form. It is therefore desirable to have a single hub component 300, 301 that will support all, or at least a selection of desired canopy forms without the requirement for several hub components specifically designed for to support a particular canopy form.
In some embodiments, the main hub of the umbrella is utilised at the top and the bottom of the canopy and rib assembly. The hub is a clamshell design constructed from an upper and lower part but could also be formed in two or more pieces and joined to form a unitary body. The parts may be fixed together by any conventional means such as glue, clips, screws or bolts. A ledge or support shape is created around the periphery of the hub which accepts the pin or axle details of the ribs. These channel details are formed in two planes which allows two or more location options for the receiving pivot axle thus allowing a single hub to be used for multiple canopy shape and style options.
For example, a channel at 45° to the main spar is suitable for square and octagonal shaped canopies. A channel between 10° and 35° to the perpendicular axis of the main spar will allow rectangular shaped canopy to be formed.
The hub can be formed from any cast metal or injection moulded plastic which allows receiving channels to be formed. The number of channels around the hub can number between four and twelve. As well as the receiving details for the ribs, one half of the hub construction also has receiving details for the main spars. This can be in the form of a single prong with the main spar saddling the prong, it could be a 2-pronged design with the main spar nestled in between the prongs but it could also be any number of prongs or support channels.
Referring to
The hub body may be formed from several components that are bought together. For example,
In some embodiments, the hub includes one or more devices such as electronic gadgets.
For example,
The securement device 400 has a strap 404 wound onto a spindle 405. In some embodiments, the strap is mechanically biased onto the spindle by a clock spring 406. The spindle and strap are contained within a housing 402 with an entry cover 401. The housing 402 is adapted for fitment into the interior region of the mast 100 as shown by
