Description

[Technical field]

[0001] The present invention relates to the field of umbrellas, and in particular to an umbrella that can be manually opened and automatically closed. [Background technology]

[0002] In conventional umbrellas that can be opened manually and closed automatically, the multi-jointed center pole is quickly bent and folded down by the umbrella closing spring when closing, which makes the folding ribs easy to hit the user's hand, adversely affecting the usability of the user. In consideration of this problem, an umbrella closing structure has been developed that does not retract the tube at the bottom end of the center pole when closing automatically, but this type of umbrella closing structure makes it difficult to retract the center pole because the retracted length of the center pole is rather large when retracting it completely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In order to more completely and clearly disclose the technical means of the present invention and the effects achievable thereby, the present invention will be described in detail below in conjunction with the accompanying drawings and symbols disclosed.

[0019] Please refer to Figures 1 to 10. As shown in Figures 1 to 10, an umbrella that can be opened manually and closed automatically according to one embodiment of the present invention includes a multi-stage center pole 1, a top roller 2, a bottom roller 3, an umbrella head 4, a folding umbrella rib 5, and an umbrella closing assembly 6. The multi-stage center pole 1 has at least three stages, and includes tube bodies 101 that are fitted from top to bottom. A long hole 11 is formed in the side wall of the bottom tube body 101 of the multi-stage center pole 1. A locking hole 12 is formed in the side wall of the middle tube body 101 or the side wall of the top tube body 101 included in the multi-stage center pole 1. The top roller 2 and the umbrella head 4 are respectively combined with the upper and lower ends of the multi-stage center pole 1. The bottom roller 3 is movably fitted into the multi-stage center pole 1. The top roller 2 and the bottom roller 3 are respectively pivotally attached to the folding umbrella rib 5. The folding umbrella bone 5 is provided with a closing spring 51. The above-mentioned closing assembly 6 includes a fixed pulley 61, a closing pull cord 62, an elastic hook member 63, a pull sleeve 64, a connecting member 65, and a linking pull cord 66. The above-mentioned fixed pulley 61 is rotatably combined with the upper wheel 2. The outer end of the above-mentioned closing pull cord 62 is wound around the fixed pulley 61 and combined with the lower wheel 3, and the inner end of the closing pull cord 62 is stretched and inserted into the multi-stage middle rod 1 and fixed. The above-mentioned elastic hook member 63 is combined into the multi-stage middle rod 1 and connected to one tube body 101 of the multi-stage middle rod 1. The elastic hook member 63 is movably engaged with the locking hole 12. The above-mentioned pull sleeve 64 is movably fitted on the outside of the lowest tube body 101 of the multi-stage middle rod 1. The connecting member 65 is inserted into the long hole 11 of the multi-stage center pole 1, and the outer end of the connecting member 65 is connected to the pull sleeve 64. The inner end of the connecting member 65 is connected to one end of the interlocking drawstring 66. The other end of the interlocking drawstring 66 is connected to the elastic hooking member 63. In the multi-stage center pole 1, the tube body 101 having the locking hole 12 and the tube body 101 combined with the elastic hooking member 63 can be movably engaged with the adjacent tube body 101 via the hook 102, so that the multi-stage center pole 1 can be reliably deployed and positioned. When the umbrella that can be opened manually and closed automatically according to one embodiment of the present invention is in a completely closed state, the elastic hooking member 63 releases the engagement with the locking hole 12, completely stores each tube body 101 of the multi-stage center pole 1, completely stores the foldable umbrella bones 5, and stores the pull sleeve 64 in the umbrella head 4.When the manually opening and automatically closing umbrella of the present invention is in a fully opened state, when each tube body 101 of the multi-stage center pole 1 is fully unfolded, the folding ribs 5 are fully unfolded and the elastic hooking members 63 are engaged with the locking holes 12.

[0020] The operating principle of this invention is that when opening this umbrella, the user pushes up the lower roller 3 to fully unfold the multi-stage center rod 1 and the folding ribs 5. When pushing up the lower roller 3 to position it, the elastic hooking member 63 engages with the locking hole 12 of the multi-stage center rod 1 by its own spring action, and when the umbrella that can be opened manually and closed automatically according to this invention is kept in a fully opened state, the interlocking pull cord 66 is in a taut state. When closing this umbrella, the user pulls down the pull sleeve 64, which displaces the interlocking pull cord 66 downward via the connecting member 65, and the interlocking pull cord 66 pulls and deforms the elastic hooking member 63, and the elastic hooking member 63 disengages from the locking hole 12 of the multi-stage center rod 1, and then the folding ribs 5 are folded under the action of the closing spring 51 to displace the lower roller 3 downward. After that, when the multi-stage center pole 1 is pulled by the closing pull string 62 to automatically retract a part of it, the interlocking pull string 66 loosens, and the umbrella that can be opened manually and closed automatically becomes a semi-closed state. The locking hole 12 is formed in the middle tube 101 or the top tube 101 of the multi-stage center pole 1. When the pull sleeve 64 is pulled down to automatically retract a part of the multi-stage center pole 1, the bottom tube 101 of the multi-stage center pole 1 is not retracted, so that the folding ribs 5 are prevented from hitting the user's hand when closing the umbrella, which improves the user's convenience. After the umbrella that can be opened manually and closed automatically according to the present invention becomes a semi-closed state, the user can apply force to the upper wheel 2 and the umbrella head 4 to completely retract the multi-stage center pole 1, and the umbrella that can be opened manually and closed automatically according to the present embodiment becomes a completely closed state. In the umbrella of this embodiment, which can be opened manually and closed automatically, when the pull sleeve 64 is stored inside the umbrella head 4, the multi-stage center pole 1 becomes easier to store, which helps to reduce the storage length of the multi-stage center pole 1, and the size of the umbrella when fully closed can be reduced.

[0021] In order to more completely and clearly disclose the technical means of the present invention and the effects achievable thereby, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and symbols disclosed.

[0022] (First embodiment) Please refer to Figures 1 to 4. As shown in Figures 1 to 4, the multi-stage center pole 1 of the umbrella that can be opened manually and closed automatically according to the first embodiment of the present invention has three stages. The hole diameter of each tube body 101 of the multi-stage center pole 1 increases sequentially from top to bottom. The locking hole 12 of the multi-stage center pole 1 is formed in the upper part of the second stage tube body 101 from the top to bottom of the multi-stage center pole 1. The elastic hook member 63 is attached to the lower part of one tube body 101 (i.e. the uppermost tube body 101) from the top to bottom of the multi-stage center pole 1. Therefore, when the pull sleeve 64 is pulled down to automatically retract a part of the multi-stage center pole 1, the upper two stages of the tube body 101 of the multi-stage center pole 1 are retracted. The folding umbrella ribs 5 correspond to three folding umbrella ribs.

[0023] In the first embodiment of the umbrella that can be opened manually and closed automatically, the upper end of the elastic hook member 63 is provided with an attachment part 631 connected to one tube body 101 of the multi-stage center pole 1.
