The present invention relates to the field of umbrellas, in particular to a novel side-arm umbrella structure.
Side-arm umbrella is an umbrella whose umbrella body is located at one side of the bracket. When in use, the bracket is close to the wall, and the use area under the umbrella body can be used for placing tables and chairs or for pedestrians to pass through. Side-arm umbrella is favored by many consumers in beaches and other amusement places.
Side-arm umbrellas in the prior art, such as U.S. patent publication No. US20140311537A1, disclose an umbrella having the crown of the canopy coupled to a support structure via a pivot joint that is structured and configured to allow swiveling and/or tilting of the canopy with ease by a user, in more than one plane or with more than one degree of freedom with respect to the support structure. The canopy frame includes a longitudinal central support hub, and the pivot joint is rotatable about a rotation axis, wherein the axis of the canopy support hub makes a fixed or variable non-zero angle with respect to the pivot joint rotation axis. As a result of the angle between the pivot joint rotation axis and the canopy support hub axis. The rotation of the pivot joint causes tilting of the canopy support hub axis, thus tilting the canopy to change its orientation.
With this solution, the folding and unfolding structure of the side-arm umbrella is mainly composed of a hand crank and a pull wire, and the extension and shortening of the pull wire are controlled by the hand crank to further realize the unfolding and storage of the umbrella surface. However, with the passage of use time, the pull wire may loosen or even break, resulting in a short service life of the product. Once the pull wire breaks, it will cause harm to users under the umbrella surface, which has certain security risks and requires regular maintenance. At the same time, due to its soft characteristics, the pull wire needs regular maintenance.

As shown in
In a preferred embodiment of the present invention, the lower end of the umbrella brace 15 is hinged on the lower hinge disc 16, and the upper end of the umbrella brace 15 is hinged on the middle of the umbrella rib 9, the first diagonal pull rod 7 and the second diagonal pull rod 14, and the upper end of the umbrella rib 9 is hinged on the upper hinge disc 10, and a plurality of umbrella ribs 9 and umbrella braces 15 are evenly distributed along the upper hinge disc 10.
In order to make the extension and storage of the side-arm umbrella more stable, as shown in
In this embodiment, the driving gear 11 at the upper end of the first diagonal pull rod 7 is driven, and then the driven gear 13 is driven to rotate by two intermediate gears 12, so as to drive the free end of the second diagonal pull rod 14 to approach the first diagonal pull rod 7. In some embodiments, the number of intermediate gears 12 can be configured according to actual needs, which can be one or more, or the driving gear 11 can be directly engaged with the driven gear 13 without the intermediate gears 12.
As shown in
As a preferred embodiment of the present invention, in order to make the side-arm umbrella more compact after storage and reduce the failure rate of the side-arm umbrella during deployment and storage, the lower hinge disc 16 is configured to move downward during the storage of the side-arm umbrella.
Specifically, as shown in
In this embodiment, due to the installation of the umbrella post assembly, the lower hinge disc 16 will be blocked by the umbrella post assembly when it moves upward, so that the lower hinge disc 16 can only move downward, and the downward displacement of the lower hinge disc 16 can make the folding and unfolding force of the umbrella body more uniform, and the storage is more compact and space-saving. At the same time, the length of the umbrella brace 15 and the hinge position between the umbrella brace 15, the first diagonal pull rod 7, the second diagonal pull rod 14 and the umbrella rib 9 have more choices, and the side-arm umbrella has more configurations to meet the use needs of different users.
In some embodiments, elastic components (not shown in the figure) can also be arranged in the upper umbrella post 17 and the lower umbrella post 18, and the storage of the side-arm umbrella can be assisted by the elasticity of the elastic components.
In order to facilitate users to use the side-arm umbrella, the present invention provides a driving mechanism to drive the main gear 11 to rotate.
Specifically, as shown in
In this embodiment, the user drives the power gear 5 to rotate by turning the crank hand crank 4, and then drives the driving gear 11 to rotate by using the chain 6. The chain transmission mode can maintain the accurate average transmission ratio, and has high transmission efficiency and strong overload capacity, and at the same time, the structure is simple and reliable, which can greatly prolong the service life of the side-arm umbrella.
In some embodiments, for the convenience of users, a motor-driven mode can also be adopted, for example, a motor is used to drive the power gear 5 to rotate instead of the crank hand crank 4, thus saving the physical strength of users and facilitating their operation. In some embodiments, the motor can also take the form of remote control, and the folding of the side-arm umbrella can be remotely controlled by configuring the user end.
According to the present invention, by connecting each umbrella rib with the upper hinge disc, the potential safety hazard of pulling wire breakage in the prior art is avoided, and the safety of users is greatly guaranteed.
In another embodiment of the present invention, the hand crank 4 is also provided with a locking mechanism (not shown in the figure), which can limit the rotation of the hand crank 4, thus limiting the transmission of the chain, and finally fixing the unfolding and storing state of the side-arm umbrella. In some embodiments, the locking mechanism can adopt bolt locking mode or other locking modes, as long as it can limit the transmission of the chain.
As a preferred embodiment of the present invention, the umbrella body of the present invention can have different unfolding and folding angles relative to the bracket 2.
Specifically, as shown in
In this embodiment, the umbrella body uses the slider 3 to move up and down on the bracket 2 to realize a variety of deployment and storage angles, and the user can adjust the corresponding angles according to different use requirements. For example, on the beach, the user can adjust the corresponding deployment angle of the umbrella body according to the angle of solar irradiation to cope with ultraviolet irradiation.
In order to further facilitate users to use the side-arm umbrella, as shown in
In some embodiments, the base 1 can be configured with a plurality of accommodating cavities to accommodate water or other heavy objects, so as to increase the weight of the base 1 and make the side-arm umbrella not easy to overturn. In other embodiments, the base 1 can also be configured with a mobile kit, so that the side-arm umbrella can be moved by using the base 1, which is convenient for users to use in different positions. In other embodiments, the base 1 can be directly fixed to the ground, making the side-arm umbrella more difficult to overturn. In some embodiments, the bracket 2 can be directly fixed on a wall or a wall without setting the base 1, and the bracket 2 will be configured as a connector for connecting the wall or the wall.
In specific use, in order to facilitate the understanding of the present invention, it is described with the attached drawings:
Overall angle adjustment of the umbrella body: the slider 3 can slide through the bracket 2 and is equipped with a locking mechanism. After the locking mechanism is unlocked, the overall movement of the umbrella body can be realized through the vertical sliding of the slider 3 on the bracket 2, which shows that the umbrella body switches back and forth between the horizontal state and the vertical state. After adjusting the angle between the umbrella body and the bracket 2, the locking mechanism is locked again, and the umbrella body can be fixed at the required angle.
Opening or closing the umbrella body: when the hand crank 4 is rotated, the driving gear 5 rotates to drive the driving gear 11 to rotate, and the driving gear 11 rotates the driven gear 13 through two intermediate gears 12, and the driven gear 13 and the second diagonal pull rod 14 are fixed (the driven gear 13 cannot freely rotate on the second diagonal pull rod 14), thus realizing the change of the included angle between the second diagonal pull rod 14 and the first diagonal pull rod 7. Meanwhile, the second diagonal pull rod 14 drives a plurality of ribs 9 to move synchronously through the fabric on the umbrella surface, and the upper hinge disc 10 and the lower hinge disc 16 can be designed to be close to or far away from each other by the upper umbrella post 17 and the lower umbrella post 18, that is, the umbrella body is unfolded or folded as a whole.
