1. Field of the Invention
This invention relates to an umbrella holder, particularly to one safe and comfortable in use and convenient and quick in operation.
2. Description of the Prior Art
A conventional umbrella holder, as used for a golf handcart, is assembled on a handle or a scoreboard. The conventional umbrella holder, as shown in
However, the conventional umbrella holder has the following drawbacks that need to be improved.
The first objective of this invention is to offer an umbrella holder integral in the external look, and safe and comfortable in use.
The second objective of this invention is to offer an umbrella holder quick in its angle adjustment and in disassembly and convenient in operation.
The umbrella holder in the present invention includes a hollow tube for placing an umbrella handle therein, a fixing mechanism assembled on the tube provided with a rotary button with a threaded rod that is screwed with a fixing block positioned in the interior of the tube, able to tighten or release the umbrella handle, with a stop plate fixing the threaded rod of the button in position. The holder also has a first angle-adjusting mechanism positioned under the tube, and the first angle-adjusting mechanism is disposed with an immovable geared disk and a movable geared disk matching each other. The movable geared disk is assembled on a rotary base set thereon with an eccentric actuating member operated to make the immovable geared disk engaged with or disengaged from the movable geared disk. The holder further has a second angle-adjusting mechanism mounted under the first angle-adjusting mechanism and provided with an immovable geared disk and a movable geared disk matching each other. The immovable geared disk is positioned at the underside of the rotary base and has a fixed shaft secured thereon. The movable geared disk is fixed at the upper end of a base that is pivotally disposed with an eccentric actuating member able to be clamped with or separated from the fixed shaft for making the immovable geared disk engaged with or disengaged from the movable geared disk.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of an umbrella holder in the present invention, as shown in
The fixing mechanism 5 assembled on a hollow tube 50 is composed of a rotary button 51 with a threaded rod, a stop plate 52 and a fixing block 53. The threaded rod of the rotary button 51 is inserted in the interior of the tube 50 and has its end screwed with the fixing block 53, with the rotary button 51 flatly and closely attached in a recess 54 at an outer side of the tube 50. The stop plate 52 has its lower end mounted astride on the threaded rod of the rotary button 51 and its upper end inserted in the tube 50 for stabilizing and positioning the rotary button 51 and letting the threaded rod turn idle. When the rotary button 51 is turned around, the fixing block 53 will be actuated to shift backward and forward for releasing or tightening an umbrella handle (A) in the tube 50, but the rotary button 51 will not be shifted together with the fixing block 53.
The first adjusting mechanism 6 is composed of an immovable geared disk 61 positioned under the tube 50, a rotary base 62 having an upper side provided with a movable geared disk 621 for matching with the immovable geared disk 61, a shaft rod 63 inserted through the center of the two geared disks 61, 621, a spring 64 fitted on the shaft rod 63 and located between the immovable geared disk 61 and the rotary base 62, and an eccentric actuating member 65 eccentrically and pivotally connected with the shaft rod 63 and positioned in a recessed chamber 622 at one side of the rotary base 62. When pressed downward, the eccentric actuating member 65 will push the rotary base 62 to let the two geared disks 61, 621 engaged mutually for carrying out adjustment and positioning. When the eccentric actuating member 65 is pulled upward, the rotary base 62, by the resilience of the spring 64, will disengage two geared disks 61, 621 from each other for adjusting angles (directions), and then press down the eccentric actuating member 65 once again for positioning.
The second adjusting mechanism 7 assembled under the first adjusting mechanism 6 is composed of an immovable geared disk 71 positioned at the lower end of the rotary base 62, a fixed shaft 72 protruding downward from the center of the fixed geared disk 71 and having its lower end cut with an annular engage recess 721, a flat-bottom base 73 fitted on the fixed shaft 72 and having its upper end provided with a movable geared disk 731 to match with the immovable geared disk 71 and one side formed with a recessed chamber 732. The second adjusting mechanism 7 is further provided with an eccentric actuating member 74 that is eccentrically and pivotally connected with one end of the recessed chamber 732 of the flat-bottom base 73 and has an engage hook 741 to be engaged with the engage recess 721 of the fixed shaft 72. If the eccentric actuating member 74 is pressed down, the engage hook 741 is to be engaged with the engage recess 721, fixing the flat-bottom base 73 and letting the two geared disks 71, 731 engaged with each other and positioned in place. When the eccentric actuating member 74 is pulled upward, the engage hook 741 will be separated from the engage recess 721, and the flat-bottom base 73 will be released to let the two geared disks 71, 731 disengaged from each other for facilitating angle adjustment, and then press down the actuating member 74 anew for positioning in place.
The pipe sleeve 8 assembled under the flat-bottom base 73 consists of an upper half pipe sleeve 81 and a semi-circular lower half pipe sleeve 82 combined together. Two fixing bolts 83 are secured at the underside of the flat-bottom base 73, extended downward to be inserted through both the upper and the lower half pipe sleeve 81, 82 for fixing them in position. The upper half pipe sleeve 81 has its upper end formed with a flat surface to match with the flat-bottom base 73 for facilitating them to be clamped on the scoreboard of a golf handcart. The lower end of the upper half pipe sleeve 81 and the lower half pipe sleeve 82 are respectively semi-circular shaped, able to be combined together to make up a round hole for clamping the handle pipe of a golf handcart.
As can be understood from the above description, this invention has the following advantages.
1. The threaded rod of the rotary button 51 is screwed with the female threads of the fixing block 53; therefore, when the rotary button 51 is turned around, the fixing block 53 positioned in the tube 50 will be actuated to shift forward for tightening an umbrella handle (A), or shift backward to release the umbrella handle (A) for facilitating the umbrella taken out of the tube 10, as shown in
2. To have the first and second angle-adjusting mechanism 6, 7 carrying out angle adjustment for the umbrella holder, simply press down or pull up the eccentric actuating member 65, 74, easy and quick in operation. Further, the eccentric actuating members 65 and 74 are respectively positioned and concealed in the recessed chambers 622 and 732, having a beautiful external profile.
3. By pulling up the eccentric actuating member 74 to let the engage hook 741 moved away from the engage recess 721, the second angle-adjusting mechanism 7 together with the pipe sleeve 8 will be separated from both the fixing shaft 72 and the tube 50, quick in disassembly.
4. By cooperation of the flat-bottom base 73 and the flat topside of the upper pipe sleeve 81, the umbrella holder of this invention can be firmly assembled on the scoreboard 91 of a golf handcart, as shown in
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
