Description

Technical Field

[0001] The invention relates to the technical field of umbrellas, in particular to a multifunctional umbrella for the elderly. Background Art

[0002] An umbrella is a common tool for sunshade and rainproof. It has a simple structure, is practical and convenient, and is suitable for people of all ages. With the improvement of living standards, ordinary umbrellas with a single function no longer meet people's needs, and more and more umbrellas with additional functions are designed. The elderly often need to bring an umbrella and a walking stick when going out on rainy days. It is very inconvenient for the elderly to carry two items at the same time. There is a solution in the prior art: a walking stick head is provided on the top of the umbrella surface, so that the umbrella can be used as both an umbrella and a walking stick. The middle stick of a general umbrella usually adopts a hollow design to install the locking mechanism of the umbrella. Once the elderly use the umbrella as a walking stick, the middle stick will be greatly damaged or even deformed and broken. After the middle stick is deformed, the sliding of the umbrella nest is blocked, and the umbrella will lose the opening and closing function. Even if a solid middle stick is used, the loss of the umbrella function cannot be avoided. Therefore, it is very necessary to design a durable umbrella for the elderly. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] like Figures 1 to 7 As shown, the present embodiment provides a multifunctional umbrella for the elderly, which comprises a solid center rod 3 and a plurality of ribs 2, a crutch head 4 being installed at the top of the solid center rod 3, a rib mounting frame 5 being sleeved on the upper end of the solid center rod 3, a pulling mechanism 8 being installed at the lower end of the solid center rod 3, a hinge 6 being installed at a position close to the inner end of the rib 2, the plurality of ribs 2 being evenly hinged on the rib mounting frame 5 along the circumferential direction, the inner ends of the plurality of ribs 2 being respectively connected with cables 7, the other ends of the cables 7 being respectively extended and connected to the pulling mechanism 8 of the solid center rod 3, the opening and closing of the umbrella can be achieved by operating the pulling mechanism 8, since the multifunctional umbrella for the elderly of the present embodiment does not rely on an umbrella nest to achieve the opening and closing of the umbrella, the straightness of the solid center rod 3 will not affect the opening and closing of the umbrella, and the crutch head 4 provided at the top end of the solid center rod 3 enables the umbrella of the present embodiment to be used as a crutch. The multifunctional umbrella for the elderly also includes an umbrella surface 1, an outer surface of which is provided with an umbrella rolling strap 21, one end of which is fixed at a position close to the edge of the umbrella surface 1, and a buckle assembly 22 is installed on the umbrella rolling strap 21.

[0025] In this embodiment, the pulling mechanism 8 includes a fixed ring 9, a compression spring 10, a movable ring 11 and a lifting piece which are sequentially sleeved on the solid rod 3 from top to bottom. The fixed ring 9 is fixedly sleeved on the solid rod 3, and the movable ring 11 is sleeved on the solid rod 3 and maintains axial sliding and circumferential fixation with the solid rod 3. An implementation method for the movable ring 11 to maintain axial sliding and circumferential fixation with the solid rod 3 is: a spline shaft is provided on the solid rod 3, and the inner ring of the movable ring 11 is provided with a keyway matching the spline shaft. The lifting member drives the movable ring 11 to slide along the solid rod 3, the upper end of the compression spring 10 abuts against the lower end of the fixed ring 9, the lower end of the compression spring 10 abuts against the upper end of the movable ring 11, and the cables 7 are all connected to the movable ring 11. Preferably, the lifting member is a nut 12 with a thread 13 sleeved on the solid rod 3, and the outer wall of the nut 12 is provided with anti-slip grooves 14. The working process of the pulling mechanism 8 is: rotate the nut 12 to make it move upward along the solid rod 3, and the movable ring 11 moves upward along the solid rod 3 under the lifting action of the nut 12, and rotate the nut 12 in the opposite direction, so that the nut 12 moves downward along the solid rod 3, and under the action of the compression spring 10, the movable ring 11 moves downward along the solid rod 3. Preferably, a plurality of groups of wire holes 15 are evenly arranged along the circumferential direction on the fixing ring 9, and the positions and number of the wire holes 15 correspond to the number and positions of the ribs 2. The other ends of the cables 7 pass through the corresponding wire holes 15 and extend downward to be connected to the movable ring 11. When the movable ring 11 moves up and down, the cables 7 also become loose or tightened accordingly.

[0026] In this embodiment, a plurality of groups of wire loops 18 are provided on the outer side of the middle part of the solid central rod 3. The wire loops 18 are evenly fixed on the outer side of the solid central rod 3 along the circumferential direction, and the number and position of the wire loops 18 correspond to the number and position of the ribs 2. The cables 7 pass through the wire loops 18.

[0027] In this embodiment, an iron bead 16 is provided at the outer end of the umbrella rib 2, and a magnetic ring 17 that is adsorbed and cooperated with the iron bead 16 is installed on the outer side of the fixing ring 9. After the umbrella surface 1 is folded, the iron bead 16 is adsorbed on the magnetic ring 17, which makes it convenient for the elderly to tidy up the umbrella.

[0028] In this embodiment, the crutch head 4 adopts an inverted cone design that is wide at the top and narrow at the bottom, and a plurality of suction cups 19 are provided at the upper end of the crutch head 4. Preferably, the crutch head 4 is in an inverted triangular cone shape, and the outer edge of the upper end surface of the crutch head 4 is bent downward. The suction cups 19 ensure the anti-slip ability of the crutch head 4. After the umbrella is tilted, the user can stand up the umbrella by stepping on the inverted triangular cone-shaped crutch head 4. Preferably, a group of annular grooves 20 are provided on the peripheral edge of the side of the crutch head 4. Such a design allows the crutch head 4 to bend to a certain extent when in use to better fit the ground.

[0029] The multifunctional umbrella for the elderly of the present invention adopts a solid middle rod 3, which can completely serve as a walking stick for the elderly. The folding and closing of the multifunctional umbrella for the elderly of the present invention does not depend on whether the middle rod is straight or not. When folding the multifunctional umbrella for the elderly of the present invention, it is only necessary to rotate the movable ring 11 to move the movable ring 11 upward to loosen the cable 7, and then droop the umbrella ribs 2, and then manually compress the umbrella ribs 2 to move closer to the solid middle rod 3 to complete the folding. When it is necessary to open the umbrella, it is only necessary to rotate the movable ring 11 in the opposite direction to move the movable ring 11 downward to complete the opening of the umbrella. The opening and closing operation of the umbrella can be completed at the umbrella handle, which is convenient for the elderly to operate.
