RELATED U.S. APPLICATION DATA

This is the Continuation-in-part of U.S. patent application Ser. No. 12/461,271, filed on Aug. 6, 2009, currently pending.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The instant disclosure relates to an umbrella, and more particularly to a foldable umbrella having a seamless single-piece fabric.

2. Description of Related Art

For centuries, umbrellas are utilized as weather protection tools to provide portable shelter against rain and sunlight alike. However, this well-familiarized and seemingly trivial device possesses some structural draw-backs.

As FIGS. 1 to 3 shown, a conventional umbrella includes a canopy member 1a made of a plurality of jointly seamed canopy members, a frame 2a, and a plurality of connecting pieces 3a. The frame 2a comprises a plurality of radially arranged foldable ribs 21a. The canopy member la is stitched by several pieces of gores to be laid between the ribs 21a and cover the whole ribs 21a of the frame 2a. For example, the canopy member 1 has a first piece 11a and a second piece 12a, which have a stitched portion 13a stitched on the edges thereof. The connecting piece 3a is through the stitched portion 13a and the rib 21a for fixing the canopy member 1 on the frame 2a. Via the above arrangement, an umbrella is obtained, whereby a user can shelter from sun and rain.

However, the canopy member of the conventional umbrella is made by means of stitching pieces of gores to the ribs. Such a stitching connection has some drawbacks as follow

(I) The stitching seams on the canopy member may be penetrated by water, so that the umbrella cannot provide an optimal effect of sheltering from rain.

(II) Since the canopy member is made by stitching pieces of gores, the manufacturer cannot print continuous patterns on the canopy member and thus the aesthetic feeling thereof is deteriorated.

Consequently, because of the above limitation resulting from the technical design of prior art, the inventor strives via real world experience and academic research to develop the instant disclosure, which can effectively improve the limitations described above.

SUMMARY OF THE INVENTION

The object of the instant disclosure is to provide an umbrella with seamless single-piece canopy member, whereby the penetration of rain can be prevented reliably. Furthermore, it allows the manufacture to print continuous patterns on the canopy member without generating discontinuous patterns.

In order to achieve the above objects, the instant disclosure provides a foldable umbrella with seamless single-piece canopy member, which comprises: a frame having a shaft, a runner, a plurality of stretchers and a plurality of ribs, the runner being slidably disposed on the shaft, the ribs each having a first rod, a second rod, and a third rod. Therein, the first rod having a fixing hole, one end of the first rod being connected to the distal end of the shaft, one end of the second rod being pivotally connected to the other end of the first rod, the other end of the second rod being pivotally connected to one end of the third rod, one end of each of the stretchers being together connected to the runner, and the other ends of the stretchers being connected to the first rods respectively. Further more there is a seamless single-piece canopy member integrally formed and laid on the ribs, wherein the seamless single-piece canopy member has an inside surface, an outside surface, and a plurality of fixing members bonding to the inside surface; and a plurality of connecting pieces, both ends of each connecting piece being connected to each of the fixing member and the fixing hole of each first rod respectively.

The instant disclosure has advantageous features as follows. The seamless single-piece canopy member is disposed on the ribs and connected thereto by means of the connecting pieces. Since the seamless single-piece canopy member is integrally formed without any seams, it can protect against the penetration of rain reliably. Furthermore, the manufacturer can print arbitrary patterns on the external surface of the seamless single-piece canopy member, and the problem occurred in a canopy member that the patterns are not continuous due to the seams can be overcome.

When the foldable umbrella is opened or folded, the connecting pieces are connected to the seamless single-piece canopy member firmly, so that the seamless single-piece canopy member can be unfolded or folded together with the ribs reliably. The canopy member does not collapse loosely or become disordered. Thus, it is convenient for a user to use or fold.

In order to further understand the characteristics and technical contents of the instant disclosure, a detailed description relating thereto will be made with reference to the accompanying drawings. However, the drawings are illustrative only, but not used to limit the scope of the instant disclosure.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 4 to 9. The instant disclosure provides a foldable umbrella with seamless single-piece canopy member, which comprises a frame 1, a seamless single-piece canopy member 2, and a plurality of connecting pieces 3.

Please refer to FIGS. 4 to 7, which show the first embodiment of the instant disclosure. The frame 1 comprises a shaft 11, a runner 12, a plurality of stretchers 13, a plurality of ribs 14, and a handle 15.

The shaft 11, the stretchers 13, and the ribs 14 are made of light metal material. One end of each of the ribs 14 is together connected to one end of the shaft 11. Via this arrangement, the ribs 14 are radially connected to the shaft 11. The ribs 14 each comprise a first rod 141, a second rod 142, and a third rod 143. The first rid 141 has a fixing hole 1411. The fixing hole 1411 is formed for the penetration of the first rod 141. One end of the first rod 141 is connected to the distal end of the shaft 11. One end of the second rod 142 is pivotally connected to the other end of the first rod 141. The other end of the second rod 142 is pivotally connected to one end of the third rod 143. The runner 12 is slidably disposed on the shaft 11. One end of each of the stretchers 13 is together connected to the outer peripheral surface of the runner 12. The other end of each of the stretchers 13 is connected to the first rods 141 of the ribs 14 respectively.

The handle 15 is provided on the other end of the shaft 11, so that a user can grip the handle 15. Since the handle is well-known, the description thereof is omitted herein.

The seamless single-piece canopy member 2 is formed integrally without stitching and made from water-proof polymeric materials, cottons, or TC (fabric with cotton and cotton and polyester mixture). The seamless single-piece canopy member 2 is laid on the ribs 14 directly without any stitching. The seamless single-piece canopy member 2 has an inside surface 22, an outside surface 23, and a plurality of fixing members 21 that are bonded to the inside surface 22 of the seamless single-piece canopy member 2 to correspond to the fixing holes 1411 respectively. Each of the fixing members 21 is a small piece of cloth connected to the inside surface 22 of the seamless single-piece canopy member 2 by means of adhesive so as to correspond to the fixing hole 1411.

In the first embodiment, the connecting piece 3 is a thread penetrating the fixing hole 1411 of the first rod 141 to be connected to the fixing member 21. In this way, the seamless single-piece canopy member 2 can be laid on the ribs 14 firmly. When the runner 12 slides on the shaft 11, it will drive the stretchers 13 and the ribs 14 to move, so that the seamless single-piece canopy member 2 can be unfolded or folded.

Please refer to FIG. 8, which shows the second embodiment of the instant disclosure. The fixing member 21 and the connecting piece 3 are formed in single piece which is an adhesive thread. The adhesive thread is a plastic thread, which has a fixing member 21, a transverse rod 32 extending from the fixing member 21, and a stopper rod 31 extending from the end of the transverse rod 32. The fixing portion 21 is adhered to the inside surface 22 of the seamless single-piece canopy member 2 via adhesive or a hot melting process. The transverse rod 32 and the stopper rod 31 penetrate the fixing hole 1411 to be transversely engaged with the first rod 141. In this way, the second embodiment can achieve the same effect as that of the first embodiment.

Please refer to FIG. 9, which is the third embodiment of the instant disclosure. Like the first embodiment, the inside of the seamless single-piece canopy member 2 is similarly provided with a plurality of fixing members 21 which is adhered to the inside surface 22 of the seamless single-piece canopy member 2. The connecting piece 3 is a binder for penetrating the fixing member 21 and the fixing hole 1411 to bind them together. In this way, the third embodiment can achieve the same effect as that of the previous two embodiments.

It should be noted that the above three embodiments are merely preferred modes for carrying out the instant disclosure. Any embodiment in which a seamless single-piece canopy member 2 is provided on the foldable umbrella and the seamless single-piece canopy member 2 is connected to the first rods 141 of the ribs 14 via the connecting pieces 3 can be considered as a modification equivalent to the instant disclosure.

The instant disclosure has advantageous features as follows.

The seamless single-piece canopy member 2 is disposed on the ribs 14 and connected thereto by means of the connecting pieces 3. Since the seamless single-piece canopy member 2 is integrally formed without any seams, it can protect against the penetration of rain reliably.

Further, the manufacturer can print arbitrary patterns on the external surface of the seamless single-piece canopy member 2, so that the problem occurred in a canopy member that the patterns are not continuous due to the seams can be overcome.

When the foldable umbrella is opened or folded, the connecting pieces 3 are connected to the seamless single-piece canopy member 2 firmly, so that the seamless single-piece canopy member 2 can be unfolded or folded together with the ribs 14 reliably. The canopy member does not collapse loosely or become disordered. Thus, it is convenient for a user to use or fold.

While the instant disclosure has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the instant disclosure needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
