The telescoping mechanism (50) is disposed between the upper seat (11) and a cap (40) and composed of a fixing rod (51) and an elastic member (52). The fixing rod (51) is formed with a connecting portion (511) fastened to the cap (40). The elastic member (52)has an extending length greater than a length of the fixing rod (51). The elastic member (52) is clamped between the fixing rod (51) and the upper seat (11), so that the telescoping mechanism (50) makes the cap (40) move upward and downward.
Description
- The invention relates to umbrellas, particularly to collapsible umbrellas.
- An umbrella or parasol is a canopy designed to protect against rain or sunlight. A collapsible (or collapsible) umbrella has sliding levers to be shrunk and is easy to be carried or stored.
- A typical collapsible umbrella is shown in
FIG. 1 , the canopy slightly protrudes at the ferrule. As shown inFIG. 2 , such a collapsible umbrella will cause the ferrule to be protrudent. This protrusion will extend the closed length of the umbrella and spoil the appearance of the umbrella. - An object of the invention is to provide a collapsible umbrella, which can make a pretty quasi-conoid center when the umbrella is opened and make the ferrule not to be protrudent when the umbrella is retracted.
- To accomplish the above object, the collapsible umbrella of the invention includes a shank, an arm assembly and a telescoping mechanism. The shank has an upper seat and a lower seat. The arm assembly has a plurality of arms for supporting a canopy and connects with the upper seat and the lower seat. The lower seat is axially slidably disposed on the shank so as to make the arm assembly collapsible. The telescoping mechanism is disposed between the upper seat and a cap and composed of a fixing rod and an elastic member. The fixing rod is formed with a connecting portion fastened to the cap. The elastic member has an extending length greater than a length of the fixing rod. The elastic member is clamped between the fixing rod and the upper seat, so that the telescoping mechanism makes the cap move upward and downward.

FIGS. 1 and2 are schematic views of a conventional collapsible umbrella; -
FIG. 3A is a sectional plan of the invention; -
FIG. 3B is a partially exploded view of the invention; -
FIG. 3C is an enlarged view of circle A inFIG. 3A ; -
FIG. 4A is a schematic view of the invention in a retracted status; and -
FIG. 4B is an enlarged view of circle B inFIG. 4A . - An embodiment is now described with reference to the figures, where like reference numbers indicate identical or functionally similar elements. While specific configurations and arrangements are discussed, it should be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other configurations and arrangements can be used without departing from the spirit and scope of the description. It will be apparent to a person skilled in the relevant art that this can also be employed in a variety of other applications other than what is described herein.
- Please refer to
FIG. 3A , which shows a preferred embodiment of the invention. Thecollapsible umbrella 100 of the invention includes ashank 10, anarm assembly 20, atelescoping mechanism 50 and acanopy 30. - The
shank 10 is provided with anupper seat 11 and alower seat 12. Thearm assembly 20 has a plurality of arms for supporting thecanopy 30 and connects with theupper seat 11 and thelower seat 12. Thus thelower seat 12 can slide on theshank 10 to make thearm assembly 20 and thecanopy 30 collapsible. - Please refer to
FIG. 3B . Thetelescoping mechanism 50 is disposed between theupper seat 11 and acap 40 and composed of afixing rod 51 and anelastic member 52. Thefixing rod 51 is formed with a connectingportion 511 fastened to thecap 40. And thecanopy 30 is clamped between thecap 40 and the connectingportion 511. As a result, the center of thecanopy 30 can be pulled up to form aprotrudent top 70 like a sloped turret as shown inFIG. 3A . - The
cap 40 and connectingportion 511 can be further formed with afirst engagement portion 61 and asecond engagement portion 62, respectively, so that thecanopy 30 can be held more firmly. - Please refer to
FIG. 3C . Theelastic member 52 has an extending length greater than a length of thefixing rod 51. One end of theelastic member 52 is axially received in thefixing rod 51. Alternately, theelastic member 52 may be passed through by thefixing rod 51. The other end of theelastic member 52 is axially passed through by abar 111 of theupper seat 11. Thus theelastic member 52 is clamped between thefixing rod 51 and theupper seat 11. In the shown embodiment, theelastic member 52 is a spring, but not limited to this. - The
upper seat 11 is further formed with asleeve 112 to receive the top of theshank 10. Moreover, theupper seat 11 is further formed with a plurality of connectingbases 113 for connecting thearm assembly 20 so that thetelescoping mechanism 50 makes thecap 40 move upward and downward. - Please refer to
FIGS. 4A and4B . When thelower seat 12 is pulled down to retract thearm assembly 20, thecanopy 30 will pull thecap 40 down and theelastic member 52 will be compressed. As a result, the top 70 can be shrunk without being protrudent from thearm assembly 20 and the closed length of thecollapsible umbrella 100 can be shortened when thearm assembly 20 is retracted. When thearm assembly 20 is spread, thecanopy 30 is also spread and is not pulled by thecap 40, and theelastic member 52 stretches to restore the conic shape of the top 70 as shown inFIG. 3A .
