BACKGROUND OF THE INVENTION

A conventional drip cup may be provided to collect rainwater dripping down or drained from an umbrella cloth of a wet umbrella. Such a drip cup is connected with a telescopic umbrella cover comprising a plurality of cylindrical elements of diameters which gradually decrease towards a tip portion of the umbrella. When extended, the cylindrical elements shield a wet umbrella to prevent water dripping or contamination to the surroundings, but when retracted, the umbrella may be opened for use. The telescopic mechanism and drain cup is complex and may cause inconvenience in operation and high production cost. In addition, the collecting cup should be operated to decant the accumulated water, increasing its inconvenience, otherwise the water may be accidentally spilled or may drain outwardly to moisten or contaminate the surroundings, possibly causing hygiene problems.

SUMMARY OF THE INVENTION

The present invention provides a water collector for an umbrella as defined in the Claims.

BRIEF DESCRIPTION OF THE DRAWINGS

The following description and the accompanying drawings referred to therein are included by way of non-limiting example in order to illustrate how the invention may be put into practice. In the drawings:

Figure 1 is an exploded view showing the elements of the present invention.

Figure 2 is an illustration showing an assembled water collector of the present invention fitted on an umbrella tip portion for collecting rainwater from a wet umbrella cloth.

Figure 3 shows an opened umbrella when inverted from Fig. 2 for shielding use.

Figure 4 shows a squeezing operation for removing rainwater absorbed in the water collector of the present invention when opening the umbrella.

DETAILED DESCRIPTION OF THE DRAWINGS

The water collector comprises a catcher member 1, an absorbent lining 2 secured on an inner surface 10 of the catcher member 1, a web member 3 secured on an outer surface 10a of the catcher member 1, and a retainer 4 fitted in a central portion of the catcher member 1 for securing the water collector on a tip portion 51 of an umbrella 5, especially on a junction portion 53 of the umbrella 5 between the tip portion 51 and an umbrella cloth 52.

The catcher member 1 is made of elastomer materials such as plastic materials having good elasticity and is generally formed in a conical, semi-spherical or cup-like shape, concave downwardly when mounted on an umbrella tip portion 51 facing downwardly. The catcher member includes a collar portion 11 formed on a central portion of the catcher member 1, a central hole 12 formed through the collar portion 11 engageable with the retainer 4 secured to a junction portion 53 between the tip portion 51 and the umbrella cloth 52, a plurality of resilient arms 13 radially protruding upwardly arcuately from the collar portion 11 to form a cup shape circumferentially disposed around the junction portion 53 adjacent to the tip portion 51 of the umbrella 5, and a plurality of radial slots 14 radially formed in the catcher member 1 each slot 14 separating two neighbouring resilient arms 13. Each resilient arm 13 is bent upwardly arcuately to form a generally parabolic curve to produce its elasticity for resiliently clamping and squeezing the absorbent lining 2 as sandwiched in between the catcher member 1 and an opened umbrella cloth 53 as shown in Fig. 4, for squeezably draining rainwater previously absorbed in the absorbent lining 2.

The absorbent lining 2 may be made of flexible water-absorbing materials, such as cotton, fabric, fibrous materials, sponge, foams or other absorbents carried on or impregnated in an absorbent medium. The lining 2 includes a central base portion 21 secured to a collar portion 11 of the catcher member 1, a central hole 22 formed through the absorbent lining 2 engageable with the junction portion 53 between the tip portion 51 and the umbrella cloth 52 for fastening the absorbent lining 2 on the junction portion 53 of the umbrella 5, a plurality of absorbing sectors 23 radially disposed around the central base portion 21 by radially cutting a plurality of radial slits 24 in the lining 2 each radial slit 24 separating every two neighbouring absorbing sectors 23, with all absorbing sectors 23 embedded, adhered or secured to an inner surface 10 of each resilient arm 13 of the catcher member 1.

The web member 3 may be made of flexible thin-layer sheet, membrane or film elastomeric materials secured to an outer surface portion 10a of the catcher member 1 by adhering or securing an outer surface of each resilient arm 13 of the catcher member 1 to an inner surface of the web member 3. The web member has a central hole 31 formed in a central portion of the web member 3 engageable with the collar portion 11 of the catcher member 1 to be fitted on the tip portion 51 of the umbrella 5.

The web member 3 connect every two neighbouring resilient arms 13 so as to provide a full "anvil" base to co-operatively squeeze a moistened absorbent lining 2 sandwiched between the opened umbrella cloth 53 and the catcher member 1 secured with the web member 3 which shields the radial slots 14 among the resilient arms 13 of the catcher member 1. If eliminating such a web member 3, the catcher member 1 will reduce its total area, because of the area of the "void" slots 14, to decrease water removing efficiency when squeezing the water absorbed in the lining 2 in co-operation with the opened umbrella cloth 53.

The web material 3 may be made of plastic materials such as polyethylene (PE), fabric material, or any other suitable materials.

The retainer 4 includes a cylindrical sleeve 40 having a central sleeve hole 41 engageable with a tip portion 51 of the umbrella 5 with the sleeve 40 engageable in the central hole 12 of the collar portion 11 of the catcher member 1 for securing the retainer 4 and the catcher member 1 on the tip portion 51 of the umbrella 5.

The cylindrical sleeve 40 of the retainer 4 is cut with a notch 42 in a cylindrical wall of the sleeve 40 for resiliently clamping the tip portion 51 of the umbrella 5.

The retainer 4 may also be integrally formed with the collar portion 11 of the catcher member 1 by plastic moulding process.

The retainer 4 may be modified to be a fastener, a clip or any other clamping devices securable to the umbrella tip portion 51. Also the retainer 4 may be provided with an adjustable mechanism for snugly fastening each tip portion of different diameters of different models of umbrellas.

When taking an umbrella of the present invention in a rainy day, a folded or retracted umbrella as shown in Fig. 2 by facing the tip portion 51 of the umbrella 5 downwardly towards a ground surface may drain the rainwater or drops gravitationally to the catcher member 1 to be absorbed in the absorbent lining 2 so as to prevent wetting or contamination to the others or the surroundings. Then, when re-using the umbrella of the present invention by opening a wet umbrella as shown in Fig. 4, the umbrella cloth 53 will be opened as urged by the tensioning springs provided on the umbrella shaft or ribs to squeeze the water previously absorbed in the lining 2 as sandwiched between the opened umbrella cloth 52 and the catcher member 1 to thereby remove the water from the water collector fixed on the umbrella. If the umbrella cloth is already saturated with much rainwater, the wet umbrella can be first rapidly shaken, thrown, cast, vibrated, or twisted to preliminarily shake off the water to reduce water quantity drained into the water collector of the present invention. This may prevent a saturation of water in the lining 2 of the present invention and thus prevent overflow of the water from the collector.

Whenever opening the umbrella of the present invention, the water previously absorbed in the water collector (lining 2) will be automatically squeezed and removed from the umbrella. Accordingly, this invention provides an umbrella which may automatically remove the collected rain water. Meanwhile, the water collector is simpler in construction, having compact volume and decreased production cost, to thereby be beneficial for its commercial uses.
