Abstract
An umbrella includes a center post having an upper end to which a crown is mounted. A number of ribs are pivoted to the crown and radially extend from the crown. A runner is movably mounted to the center post. A stretcher is mounted between the runner and each rib by having ends pivoted to the runner and the rib. A canopy is attached to and supported by the ribs. An opening/closing device includes a reel rotatably mounted in to the center post and a crank arm coupled to the reel for manually rotating the reel. A length of rope has first and second sections respectively fixed to the reel and the runner whereby by rotating the reel, the rope is wound around the reel, causing the runner to move toward the crown and driving the stretchers to expand the ribs and the canopy and thus opening the umbrella. The first and second sections of the rope have first and second diameters respectively, the first diameter being greater than the second diameter. The large first diameter helps to quickly increase the outside diameter of the reel when it is wound around the reel, thereby decreasing the force required to operate the crank for winding the rope and thus opening the umbrella.
Description
- 1. Field of the Invention
- The present invention generally relates to a large-sized umbrella, and in particular to a driving rope of rope-controlled large-sized umbrellas.
- 2. The Related Art
- Large-sized umbrellas are widely used in a variety of applications, such as beach umbrellas and garden umbrellas. FIGS. 1 and 2 of the attached drawings show a conventional large-sized umbrella, comprising, in general, an
upright center post 10 having a lower end mounted to or securely supported on the ground and an upper end to which acrown 12 is fixed, a plurality ofribs 13 pivoted to thecrown 12 and radially extending from thecrown 12, arunner 11 slidably mounted to thepost 10 and a plurality ofstretchers 14 arranged between and pivoted to theribs 13 and therunner 11. When therunner 11 is moved toward thecrown 12, theribs 13 are forced to open and expanding aflexible canopy 15 attached thereto. When therunner 11 is moved away from thecrown 12, the umbrella is closed. - A rope based opening/
closing device 16 is incorporated in the large-sized umbrella for controlling and driving therunner 11 to open/close the umbrella. The rope based opening/closing device 16 comprises a reel (not shown) for winding/unwinding arope 18 to drive therunner 11 along thecenter post 10. Acrank arm 17 is coupled to the reel for manual rotation of the reel to wind and/or unwind therope 18. - The rope that is employed in the conventional opening/closing device is of uniform cross section. Namely it has the same diameter throughout the whole length thereof. To open the umbrella, an operator must apply a substantial amount of force to the
crank arm 17 in order to overcome the gravity of thecanopy 15. This, of course, causes certain problems to people that is not strong to operate thecrank arm 17, and may sometimes lead to damage to the operator. In addition, such a great amount of force may cause breaking of the rope. - Thus, it desired to have a large-sized umbrella having an opening/closing device having no such deficiencies.
- An object of the present invention is to provide a large-sized umbrella comprising an opening/closing device having a driving rope comprised of multiple sections of different diameters.
- Another object of the present invention is to provide a large-sized umbrella that is easy to operate.
- A further object of the present invention is to provide a large-sized umbrella that is safe to the operator.
- To achieve the above objects, in accordance with the present invention, there is provided an umbrella comprising a center post having an upper end to which a crown is mounted. A number of ribs are pivoted to the crown and radially extend from the crown. A runner is movably mounted to the center post. A stretcher is mounted between the runner and each rib by having ends pivoted to the runner and the rib. A canopy is attached to and supported by the ribs. An opening/closing device comprises a reel rotatably mounted in an interior space defined in the runner and a crank located outside the runner and coupled to the reel for manually rotating the reel. A length of rope has first and second ends respectively fixed to the reel and the crown whereby by rotating the reel, the rope is wound around the reel, causing the runner to move toward the crown and driving the stretchers to expand the ribs and the canopy and thus opening the umbrella. The first and second sections of the rope have first and second diameters respectively, the first diameter being greater than the second diameter. The large first diameter helps to quickly increase the outside diameter of the reel when it is wound around the reel, thereby decreasing the force required to operate the crank for winding the rope and thus opening the umbrella.
- The present invention will be apparent to those skilled in the art by reading the following description of preferred embodiments thereof, with reference to the attached drawings, in which:
- FIG. 1 is a side elevational view of a conventional large-sized umbrella in an open condition;
- FIG. 2 is another side elevational view of the conventional large-sized umbrella in a closed condition;
- FIG. 3 is a cross-sectional view of a portion of a large-sized umbrella constructed in accordance with a first embodiment of the present invention, showing in detail an opening/closing device of the umbrella; and
- FIG. 4 is a cross-sectional view of a portion of a large-sized umbrella constructed in accordance with a second embodiment of the present invention, showing in detail an opening/closing device of the present invention.
- With reference to the drawings and in particular to FIG. 3, an umbrella constructed in accordance with the present invention comprises an umbrella frame (not labeled) comprising a
center post 10 along which arunner 11 is movable. A number ofstretchers 14 are pivoted to therunner 11 and further coupled to ribs (not shown) to drive a canopy (not shown) supported on the ribs. - The umbrella comprises an opening/
closing device 16 comprising areel 19 rotatably mounted to and transversely extending through thecenter post 10. Acrank arm 17 is coupled to thereel 19 for rotation of thereel 19. A length of rope 20 has afirst section 21 of a first diameter and asecond section 22 of a second diameter, the second diameter being smaller than the first diameter. An end of thefirst section 21 is attached to thereel 19 and an end of thesecond section 22 is attached to therunner 11. When thereel 19 rotates in a first direction, thefirst section 21 of the rope 20 is wound around thereel 19 and thesecond section 22 drives therunner 11 toward the crown to open the umbrella. When thereel 22 rotates in a reversed second direction, thefirst section 21 of the rope 20 is unwound from thereel 19 and allowing thesecond section 22 to release therunner 11 away from the crown for closing the umbrella. - In opening the umbrella, the
first section 21 of the rope 20, which has a large diameter, is wound around thereel 19. The large diameter helps to quickly increase an outside diameter of thereel 19 thereby decreasing the force required to manually rotate thereel 19. This allows the operator to open the umbrella easily with less force. - The rope20 that has two
sections second section 22. A tubular member having an inside diameter substantially corresponding to the second diameter and an outer diameter identical to the first diameter is fit over the rope 20 thereby forming thefirst section 21 that has the first diameter. - Another example of the rope is shown in FIG. 4 and is designated with
reference numeral 30. Therope 30 is made by forming layers of different thickness over an original rope that has initially the same diameter whereby alarge diameter section 31 and asmall diameter section 32 are respectively formed on opposite ends of therope 30. Similarly, thelarge diameter section 31 is attached to thereel 19 and thesmall diameter section 32 is attached to therunner 22. - In the embodiments illustrated, the
center post 10 is a tubular member. Therope 20, 30 that is made in accordance with the present invention is generally arranged inside and partially extends through thecenter post 10 thereby not causing any negative influence on the outside appearance of the umbrella. In addition, the manufacturing of therope 20, 30 only adds a small portion of extra cost thereby allowing for excellent market competition. - Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
