Definitions

  • UMBRELLA This invention relates to umbrellas.
  • a disadvantage with conventional umbrellas is that when the user reaches his destination, the wet umbrella may prove an inconvenience as there may be nowhere suitable to leave the umbrella to dry, and as a result the umbrella may undesirably wet a surrounding environment.
  • This problem ariF ⁇ s particularly when the user reaches a public place such as a restaurant or office which does not have an umbrella stand so that the rainwater drips onto the floor, or when the user enters a vehicle and the rainwater drips onto the floor of the vehicle or onto the clothes of the occupant of the vehicle.
  • Drip cups suffer from certain disadvantages.
  • One disadvantage is that when the umbrella is folded, it is not always possible to maintain the umbrella precisely vertical and therefore not all the rainwater on the canopy of the umbrella will drip down into the drain cup.
  • One situation in which the folded umbrella is not held vertically arises when the umbrella is folded on entering a building, and the user walks some distance through the building before reaching their final destination. As the user walks along through the building, the folded umbrella undergoes oscillatory motion, dropping rainwater onto the floor of the building.
  • Another situation in which the umbrella is not held vertically arises when a user enters a vehicle. The limited space available in the vehicle and the motion of the vehicle prevent the folded umbrella being held upright.
  • drain cups Another disadvantage with drain cups is that the rainwater which does collect in the drain cup may be accidentally spilled from the drain cup before an opportunity arises to empty the drain cup. Also, the wet canopy of the umbrella will wetten the user's clothes when in a crowded place like a bus, tram, etc.
  • the leading edge of the telescopic casing would push rainwater ahead of it along the canopy of the umbrella thereby spraying rainwater instead of trapping it.
  • An object of the present invention is to overcome one or more of the above mentioned problems.
  • an umbrella comprises containment means integral with or permanently fixed to the outer end of the umbrella for containing rainwater that has moved down the umbrella when wet and closed, and a waterproof/leakproof retractable sleeve or cover means capable of being extended along the closed and wet umbrella so as to retain -rainwater on the umbrella within the sleeve or cover means for subsequent movement down into the containment means.
  • a waterproof/leakproof retractable sleeve or cover means capable of being extended along the closed and wet umbrella so as to retain -rainwater on the umbrella within the sleeve or cover means for subsequent movement down into the containment means.
  • the sleeve/cover means is mounted to the containment means.
  • the outer end of the umbrella is provided with a flat outer surface to act as a support for the umbrella.
  • the sleeve/cover means encloses in its extended position a substantial portion of the canopy material of the umbrella.
  • the containment means cooperates with a collar rotatably mounted to the outer end of the sleeve/cover means in order to form a housing for storing of water.
  • the collar is formed by an inner member which is mounted to an outer member, the outer end of the sleeve/cover means being rotatably trapped between the inner and outer members.
  • the sleeve or cover means guides collected rainwater to the containment means, and the sleeve or cover means is made from a single seamless piece of material which is foldable.
  • the sleeve or cover means loosely encloses the canopy of the umbrella to provide an air gap - b
  • the sleeve or cover means is accordeon or bellow shaped.
  • the side of the sleeve or cover means is zig-zag shaped in cross-section, and in particular the side is made of a plurality of two types of portions, one type of portion being directed in one direction, which portions are longer than a plurality of portions directed in another direction.
  • the sleeve or cover means prior to assembly to the umbrella is heat treated and then immediately colded in order to give the sleeve or cover means an inherent tendency to return to its folded shape.
  • the collar is provided on the sleeve/cover means for use in extending and contracting the sleeve/cover means, the external dimensions of the collar being chosen so that the user's hand need not come into contact with the folded canopy of the umbrella when moving the collar.
  • the collar is provided for extending and contracting the sleeve/cover means, the dimensions of the collar being chosen so that in the extended position of the sleeve/cover means the outward pressure of the folded canopy of the umbrella is sufficient to keep the collar in position while at the same time allowing circulation of air to and from the inside of the sleeve/cover means.
  • an umbrella attachment for fixing to the outer end of an umbrella comprises containment means for containing rainwater that has moved down a closed and wet umbrella, and a waterproof/leakproof retractable sleeve or cover means capable of being extended along the closed and wet umbrella so as to retain rainwater on the umbrella within the sleeve or cover means for subsequent movement down into the containment means, the arrangement being so designed and arranged that rainwater can only be removed from the umbrella attachment through an open end of the sleeve or cover means.
  • an umbrella attachment for fixing to the outer end of an umbrella comprises containment means for containing rainwater that has dripped down a closed and wet umbrella, and a waterproof/leakproof retractable sleeve or cover means capable of being extended along the closed and wet umbrella so as to retain rainwater on the umbrella within the sleeve or cover means for subsequent movement down into the cor ainment means, wherein a collar is rotatably mounted to the outer end of the sleeve/cover means.
  • a method of containing and then removing rainwater on an umbrella canopy comprises: a) covering the umbrella canopy when closed and wet with an extendable sleeve or cover means; b) retracting the sleeve or cover means when the umbrella canopy is drier; and c) removing water from the end of the umbrella by inverting the umbrella.
  • Figure 1 is an elevation of a first embodiment of umbrella in accordance with the invention before use in the closed condition, and with the sleeve fully retracted;
  • Figure 2 is an elevation of the umbrella of
  • Figure 1 in use, in the opened out condition;
  • Figure 3 is an elevation of the umbrella of Figure 1 after use in the closed condition, and with the sleeve partly extended;
  • Figure 4 is an elevation of the umbrella of

  • Figure 5 is an elevation of the umbrella of Figure 1 at the start of next use, just after being opened out;
  • Figure 6 is an exploded perspective view on a larger scale of the rotatable collar of the umbrella of Figure 1;
  • Figure 7 is a plan view of the umbrella of Figure 1 after use, in the folded condition and with the sleeve fully extended;
  • Figure 8 is a cross-sectional side view of an umbrella attachment in accordance with the invention;
  • Figure 9 is an elevation of a second embodiment of umbrella in accordance with the invention before use in the closed condition, and with the sleeve fully retracted;
  • Figure 10 is an elevation of the umbrella of Figure 9 in use, in the opened out condition
  • Figure 11 is an elevation of the umbrella of Figure 9 after use in the closed condition, and with the sleeve partly extended
  • Figure 12 is an elevation of the umbrella of Figure 9 after use in the closed condition, and with the sleeve fully extended
  • Figure 13 is an elevation of the umbrella of
  • FIG 14 is an elevation of the umbrella of Figure 9, shown in a standing position.
  • an umbrella includes rainwater containment means in the form of reservoir 1 integral with the outer end of the umbrella, a retractable and extendable sleeve 2 non-rotatably mounted to the reservoir, and a hand grip in the form of a collar 3 rotatably mounted to the outer end of the sleeve 2.
  • the sleeve 2 Before use (see Figure 1) and during use (see Figure 2) of the umbrella, the sleeve 2 is fully retracted into a water resistant housing 10, which housing is formed by joining the collar 3 to the reservoir 1.
  • the umbrella canopy is collapsed and is then closed by applying hand pressure to keep the umbrella ribs together, and if the canopy is wet the collar 3 is rotated in a spiral motion up the vertically orientated umbrella to smooth and gather the canopy material/fabric of the umbrella.
  • the friction between the collar 3 and the canopy material/fabric of the umbrella is kept to a minimum as the collar is moved along the canopy material/fabric.
  • the collar 3 which is provided with an inner hole 9 (see Figure 6) is thus moved (see Figure 3) along the wet umbrella thereby fully extending the sleeve 2 (see Figure 4).
  • the handle of the umbrella is additionally twisted at the same time as the collar is rotated.
  • An alternative way of gathering the canopy is to prevent rotation of the collar by applying hand pressure to the collar, and to move the collar along the canopy as the handle of the umbrella is continually twisted by the user.
  • the lengthwise movement of the collar 3 along the umbrella causes the sleeve 2 to extend in the manner of an accordeon or bellows,
  • the rotational movement of the collar 3 and/or twisting of the umbrella handle assists in folding the umbrella canopy about the shaft of the umbrella.
  • the folding of the canopy reduces the friction between the collar 3 and the canopy fabric so that the sleeve can be rapidly and easily extended while the umbrella is held in the vertical position, and so that the rainwater on the canopy fabric is gathered into the sleeve instead of being pushed lengthwise along the umbrella ahead of the collar.
  • the diameter of the collar 3 is sufficiently large that the user's hand does not come into contact with the canopy fabric.
  • the dimensions of the collar 3 are also chosen so that in an extended position of the sleeve 2, the light outward pressure of the folded canopy fabric is sufficient to keep the collar in position without additional support.
  • the sleeve 2 is extendable to a number of alternative extended positions along the folded canopy, the collar being held in position in each of these extended positions solely by the outward pressure of the folded canopy.
  • the sleeve 2 is usually fully extended (see Figure 4) in order to cover a substantial part of the folded canopy.
  • the sleeve 2 contains the rainwater.
  • the sleeve 2 is unitary, and preferably made from a single seamless length of plastic material which is foldable, and in consequence, there are no joints through which leakage might take place. In particular, the sleeve is thus waterproof and leakproof.
  • the umbrella when it is next desired to use the umbrella, the umbrella is held vertically, that is to say with the tip of the umbrella pointing downwards, the collar 3 is then moved along the length of the umbrella to retract the sleeve 2 into the housing (see Figure 1), the ribs of the umbrella and canopy fabric are moved to their erected state, and the umbrella in the erect state is then or at the same time turned into the orientation for use, that is to say with the tip pointing upwards (see Figure 5). Collected rainwater then falls out of the housing 10 onto the top surface of the canopy fabric of the umbrella.
  • the sleeve 2 has a zig-zag configuration in cross-section wherein the sides 2a of the zig-zag directed in an outward direction are longer (eg by lmm) than the sides 2b of the zig-zag configuration directed in an inward direction whereby the sleeve 2 can easily fold up due to a suction force that is created due to the different lengths of the sides 2a and 2b.
  • the sides directed in an outward direction are shorter (eg by 1 mm) than the sides directe.. in any inward direction to give a similar suction effect.
  • the sides of the zig-zag directed in the outward direction are longer than the sides directed in the inward direction since when the sides of the sleeve are folded (ie the sleeve is retracted) and the umbrella inverted, the inner edges of the folded sides will be at a lower position than the outer edges of the folded sides such that firstly water in the sleeve and the bottom of the umbrella will not be trapped within the folded sides of the sleeve as it exits the open end of the sleeve, and secondly any water (which will be minimal) which happens to be between the folded sides of the sleeve can drain away in any case.
  • the sleeve 2 prior to assembly to the umbrella is heat treated for between 5 and 15 minutes at a temperature between 80 and 120°C before being placed into cold water in order to give the sleeve 2 a "rubber band" effect, in other words an inherent tendency to return to its folded up position.
  • the material of the sleeve is EVA material.
  • the rotational collar 3 is also shown which comprises two elements, an inner dome 3a and an outer dome 3b which is fixed relative to the inner dome 3a. Rotatably trapped between the inner and outer domes is the outer end of the sleeve 2.
  • FIG 8 shows an umbrella attachment 20 which can be attached to the end of a standard umbrella.
  • the umbrella attachment has basically the same features of the umbrella shown in Figures 1 to 7 except that the umbrella attachment of Figure 8 has an umbrella connecting member 22 with a receiving hole 24 into which the end of a conventional umbrella (not shown) is snugly positioned.
  • An additional feature of the umbrella attachment 20 is that air channels 19 are provided in the top of the collar 3 outwardly of the inner hole 9 of the collar 3 to facilitate further evaporation of water from inside the sleeve 2.
  • the feature prevents the folded wet umbrella canopy engaging the inner hole 9 from blocking water inside the attachment 20 from evaporation through the air channf .s 19.
  • FIGs 9 to 14 meanwhile disclose a folded type umbrella adapted with basically the same retractable sleeve of the umbrella shown in Figures 1 to 7.
  • the outer end of the umbrella is provided with a flat surface 11 such that the umbrella can be stood in an upright closed condition (see Figure 14) such that water can easily collect in the reservoir.
