PAGODA-SHAPED UMBRELLA

Abstract

A pagoda-shaped umbrella includes a center post, a crown fixed to an upper end of the center post, a runner movable along the center post, a plurality of ribs each coupled to the runner by a stretcher, and a canopy supported by the ribs. A canopy retainer is mounted to the canopy to move to the topmost position when the canopy is open. A collar movably fits over the center post between the runner and the crown and a pair of slide bars extending from the collar, along opposite sides of the center post and movably through openings defined in the crown. Upper ends of the bars are fixed to the canopy retainer. When the runner is moved upward to drive the stretchers and the ribs for opening the canopy, the runner gets into contact with and thus drives the collar upward, which in turn causes upward movement of the retainer to the topmost position thereby shaping the canopy as a pagoda.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side elevational view of a pagoda-shaped umbrella constructed in accordance with the present invention in an open condition;

FIG. 2 is similar to FIG. 1 but with a canopy removed to illustrate inside details of the umbrella of the present invention;

FIG. 3 is a side elevational view showing the collapse of the umbrella of the present invention, with the canopy removed;

FIG. 4 is a perspective view of a collar and slide bar assembly of the pagoda-shaped umbrella of the present invention; and

FIG. 5 is a side elevational view of a conventional pagoda-shaped umbrella with a canopy removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and in particular to FIGS. 1 and 2, which are side elevational views of a pagoda-shaped umbrella constructed in accordance with the present invention, respectively showing a canopy attached to and removed from a frame of the umbrella in an open condition, and FIG. 3, which shows the umbrella in a closed condition, the umbrella constructed in accordance with the present invention comprises a center post 10, a runner 11, a crown 12, a plurality of ribs 13 each associated with a stretcher 14, and a canopy 15.

The crown 12 is fixed to an upper end of the center post 10. The runner 11 is movable along the center post 10. Each rib 13 is coupled to the runner 11 by the associated stretcher 14 to open/close the canopy 15, which is supported by the ribs 13, with the movement of the runner 11 along the post 10 in upward/downward direction.

A canopy retainer 16 is arranged at and fixed to a center of the canopy 15. When the umbrella is open or expanded, the retainer 16 is located at a topmost position of the umbrella in a regular application, as shown in FIGS. 1 and 2.

A collar 20 is movably fit over the center post 10 between the crown 12 and the runner 11, as best seen in FIG. 4. A pair of slide bars 21 is arranged on opposite sides of and extends along the center post 10. The slide bars 21 have lower ends fixed to the collar 20 and upper ends movably extending through openings (not labeled) defined in the crown 12 and fixed to the retainer 16.

The movable extension of the slide bars 21 through the crown 12 makes a variable distance between the crown 12 and the retainer 16, as shown in FIG. 4. When the collar 20 moves along the center post 10, the slide bars 21 moves with respect to the crown 12, which causes displacement of the retainer 16 with respect to the crown 12 thereby changing the distance therebetween.

As shown in FIG. 2, when the runner 11 is driven upward along the center post 10, the ribs 13 are forced upward by the stretchers 14 thereby opening the canopy 15. The upward movement of the runner 11 brings the runner 11 into contact with the collar 20 and then causes the collar 20 to move upward with the runner 11. The movement of the collar 20 is transmitted to the retainer 16 by the slide bars 21, thereby driving the retainer 16 away from the crown 12 to the topmost position, showing an upward-projecting tee of a pagoda.

As shown in FIG. 3, when the runner 11 is moved downward along the center post 10, the canopy 15 collapses. At the same time, the collar 20 and the slide bars 21 are allowed to move downward, which brings the retainer 16 toward and eventually getting into contact with the crown 12. The overall length of the umbrella in the collapsed condition is thus shortened.

The umbrella described above is simple in construction, easy to assemble, and durable for long term use. The overall length of the umbrella after collapse is shortened, which facilitates packaging, transportation, and storage.

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.

Claims

1. A pagoda umbrella comprising: a center post;a crown fixed to an upper end of the center post;a runner movable along the center post;a plurality of ribs;a stretcher coupling each rib to the runner;a canopy supported by the ribs whereby when the runner moves along the center post, the ribs are driven by the stretchers to open/close the canopy;a canopy retainer mounted to the canopy and movable to a topmost position of the umbrella when the canopy is open, said crown and said canopy retainer being coupled to the other to provide a fixed distance therebetween;a collar movably mounted over the center post located between the runner and the crown and;a pair of slide bars extending along opposite sides of the center post and movably extending through the crown, the slide bars having lower ends fixed to the collar and upper ends fixed to the canopy retainers,wherein when the runner is moved upward. said rib and stretchers are actuated to open the canopy, the runner further engages and drives the collar upward thereby moving the slide bars and the canopy retainer upward to position the canopy retainer at the topmost position and whereby said canopy is shaped into the contour of a pagoda.
