INSIDE OUT COMPACT UMBRELLA
There have been attempts to create a folding umbrella so that once folded the wet side of the canopy folds upon itself containing any residual water on the canopy within allowing the user to handle the dry side when furling the canopy closed. This prevents the residual water on the canopy dripping on the floor or wetting the user. The design is also to facilitate folding of the frame away from the user allowing it to close through small spaces, such as the close gap of a doorway. The present innovation achieves the intended objectives whilst maintaining the size and weight of the umbrella comparable to conventional single fold folding umbrellas.
This application is a submission under 35 U.S.C. § 371 of International Application No. PCT/EP2021/050306, filed Jan. 8, 2021, which claims priority to Great Britain Application No. 2000015.4, filed Jan. 2, 2020, the disclosures of which are hereby expressly incorporated by reference herein in their entireties.
FIELD OF THE INVENTIONThe present invention primarily relates to but not limited to umbrellas.
BACKGROUND OF THE INVENTIONUmbrella frames are typically made of primary spokes that support the canopy which are themselves supported by secondary spokes that makes up the frame of the umbrella.
If the primary spokes are continuous and are not made of parts that fold relative to each other, they are generally known as stick umbrellas. In this case, one end of the primary spokes are supported by a runner that travels up and down the shaft and the other end is supported by the outer edge of the canopy. The secondary spokes are supported by runners which travels up and down the shaft on one end and they support the primary shaft on the other end with a pivot mechanism.
If the primary spokes are made from more than one part, joined by pivot like mechanisms and thus not continuous from the sliders on the shaft to the edge of canopy, they are known as collapsible, compact or folding umbrellas. The primary purpose of this is to make the umbrella shorter in closed configuration.
The inside out stick umbrella that turns its frame completely inside out has been invented by Jenan Kazim, European Patent Application No. 13774769.7. In this case the primary spoke is made expandable telescopically as continuous spokes.
SUMMARY OF THE INVENTIONThe present invention by the same inventor is particularly applicable to folding umbrellas. However, in contrast to the conventional pivot like mechanism between the primary and secondary spokes, in the present invention a sliding mechanism is used to allow the outermost segment of the primary spoke to slide over or adjacent to the secondary spoke. Therefore, the closed length of the primary spoke is much less in closed configuration than the length in the open configuration. The length of the primary spoke in the open configuration being the length of the arc from the slider on the shaft supporting the canopy to the edge of the canopy supported by the tip of the primary spoke.
The advantage of this innovative mechanism is that it allows the wet side of the canopy to be closed within itself allowing the outside of the canopy to be dry to touch.
As the primary spoke parts are enclosed within or adjacent to the secondary spokes in closed configuration, the frame is much easier to keep enclosed and protected. On conventional umbrellas where the primary spoke segment are pivoted and hang outside the secondary spokes, they can be easily damaged or poke someone.
The innovation presented here also have much better performance in the wind than the conventional type. Reacting to the wind to change its shape of the canopy exposed to the wind because the primary spoke can slide towards the shaft allowing the canopy to change shape. The configuration presented in this invention also facilitates the auto furling of the canopy fabric around the frame and the shaft in its closed configuration.
There have been attempts to create a folding umbrella so that once folded the wet side of the canopy folds upon itself containing any residual water on the canopy within allowing the user to handle the dry side when furling the canopy closed. This prevents the residual water on the canopy dripping on the floor or wetting the user. The design is also to facilitate folding of the frame away from the user allowing it to close through small spaces, such as the close gap of a doorway.
The present innovation achieves the intended objectives whilst maintaining the size and weight of the umbrella comparable to conventional single fold folding umbrellas. To open this innovative umbrella, the user presses a button to release a latch and pushes the slider up the shaft until the umbrella is fully deployed open when the slider is latched and to close it the user presses the button and moves the slider towards the handle until the frame rotates to the closed configuration. These operations are the same as the way a user opens and closes a conventional folding type of umbrella. This has been achieved by the innovative coupling and uncoupling of the movement of the sliders along the shaft to achieve the rotation of the primary spokes and tensioning of the canopy as required. It also uniquely uses telescopic spacers between the sliders to achieve the required tension in the canopy in the open configuration and achieve compact closure of the frame in closed configuration. It is important to achieve as compact closure as possible of the canopy to minimize the possibility of spillage of water enclosed.
The conventional umbrellas have the tips of the canopy at the bottom close to the handle in closed configuration and the wet side of the canopy being on the outside. In order to open a conventional umbrella, the frame expands rotating the tips of the primary spokes supporting the edge of the canopy upwards away from the shaft until the diagonal tips of the canopy attached to the primary spokes are canopy edge diameter apart. This restrains the movement of the canopy and further movement of the frame tensions the canopy.
This is obviously not possible with reverse folding umbrellas that have the canopy inside out in closed configuration. In this case, the tips of the primary spokes supporting the edge of the canopy are at the upper end of the shaft away from the handle. In this case, whilst being opened from closed configuration, the tips of the primary spokes which support the edge of the canopy rotate away from the shaft from a remote position at the end of the shaft away from the handle until the tips of the primary spokes are canopy edge diameter apart. In this case, the canopy edge restrains the primary spokes and they cannot rotate any further constraining further opening of the frame. The canopy is then restrained in upside down cone configuration. This is a fundamental problem that requires coupling and uncoupling of the rotation of the primary spokes from the tensioning of the canopy at appropriate position of the primary spoke tips attached to the canopy.
This feature is fundamental to working of any reverse folding umbrella that maintains the conventional look and size of the traditional umbrellas. Although, there have been many attempts to innovate reverse folding umbrellas, they all failed to achieve the objective outlined on this innovation because of the failure to realize that the control of the tension in the canopy and the control of the canopy diameter during the opening and closing sequences is fundamental to it. The current innovation offers an objective, highlight the fundamental problems, offer solutions and offers an approach how to practically solve these problems for compact type reverse folding umbrellas.

The present invention will now be described by way of reference to the accompanying drawings in which:
The present aspects and embodiments represent currently the best ways known to the applicant of putting the inventions into practice. However, these are not the only ways in which this could be achieved. They are illustrated referring to the drawings, and they will now be described, by way of example only.
The relative rotation between spokes 119 and 121 also pulls the connector 127 which in turn pulls the link 128 between 121 and 120. In this example, the connector 126 allows the spoke 120 slide through it. The link 128 is attached to spoke 121 so that it can rotate in the plane of the opening frame relative to 121. This rotation lifts the spoke 120 away from 121 which also lift the primary spoke 118. The lengths of 120 and 121 is selected to fully stretch the canopy 125 to the curvature required.
Movement of slider 113 which at this stage is coupled with 112 and together they are pushed towards the slider 111 tensioning the canopy in the open configuration. The spring 129 facilitates auto rotation of the spokes 121 towards 122 pulling the sliding connector 124 along the secondary spoke 119 towards the shaft facilitating the auto closing mechanism. To close the frame, the sliders 112 and 113 are pulled downwards along the shaft towards the handle. This movement initiates the closing mechanism of the frame, pulling the primary spoke inwards towards the shaft so that it can flip pass the horizontal configuration of the frame turning the canopy dry side out which is also referred to inside out. When the frame and canopy is beyond this stage, the sliders 112 and 113 are uncoupled. Further movement of slider 113 towards the slider 14 at this stage is latched to the shaft. This movement rotates the secondary spokes 119 and primary scopes 118 upwards toward the shaft closing the frame. Further movement of slider 113 couples with slider 14 and disengages it from the shaft and moves toward the close configuration of the frame and the canopy which have the dry side of the canopy on the outside and wet enclosed on the inside.
There are several ways the linkage systems can be achieved, and further alternatives are shown with examples on
