Benefits of technology
[0008]Thus, an object of the present invention is to provide an umbrella shade orientating device comprising upper, intermediate, lower segments pivoted to each other by pivot pins extending in different directions to allow the upper segment to rotate about the two different directions with respect to the lower segment for arbitrary orientation and inclination of a shade coupled to the upper segment and thus enhancing operability and convenience of use of the large-sized umbrella.
[0010]Based on the above arrangement of the present invention, the upper segment of the shade orientating device is allowed to rotate with respect to the lower segment about two directions. This allows the shade carried by the upper segment to be orientated in any desired direction by the combination of rotations of the upper and intermediate segments.
Problems solved by technology
This limits the capacity and performance of the large-sized umbrella.
However, manually rotating the central post may affect positioning of the umbrella on for example the ground for the engagement between the central post and an umbrella base that is positioned on the ground may be unexpectedly broken or gets loosened.
In addition, the operation of manually rotating the central post is troublesome.

Embodiment Construction
[0023]With reference to the drawings and in particular to FIG. 1, a large-sized umbrella, which is broadly designated with reference numeral 10, is shown and comprises a central post supporting a shade 13 at an upper end thereof. A shade orientating device constructed in accordance with the present invention, generally designated with reference numeral 20 in FIG. 1, is embodied in the umbrella 10. The shade orientating device 20 in accordance with the present invention is particularly circled with phantom lines in FIG. 1 for easy identification and is more clearly shown in FIG. 2 in an exploded form.
[0024]As shown in FIG. 1, the central post of the umbrella 10 is comprised of upper and lower sections 11, 12. The shade orientating device 20 is arranged and connecting between the upper and lower sections 11, 12 of the central post for selectively orientating the shade 13 toward any desired direction and controlling the inclination of the shade 13.
[0025]As shown in FIG. 2, the shade or...

An umbrella includes a shade orientating device arranged between upper and lower sections of a post. The upper section supports a shade. The shade orientating device includes an upper segment mounted to the upper post section, an intermediate segment connected to the upper segment by a first pivot, a lower segment mounted to the lower post section and connected to the intermediate segment by a second pivot. Thus, the upper segment is rotatable with respect to the intermediate segment about the first pivot pin and the rotation of the upper segment is controlled by a first controller. The intermediate segment is rotatable with respect to the lower segment about the second pivot pin and the rotation of the intermediate segment is controlled by a second controller. Arbitrary combinations of the rotations of the upper and intermediate segments orientate the shade at any desired direction.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to a large-sized umbrella having a post supporting a shade, and in particular to a spherical joint based shade orientating device arranged between upper and lower sections of the post to selectively orientate the shade at any desired direction.[0003]2. The Related Arts[0004]Shade orientating devices have been used in large-sized umbrellas for controlling direction of inclination of the umbrella to selectively shield against intense sun light or simply for landscaping arrangement purposes.[0005]The conventional shade orientating devices only allow the umbrella to move in a single plane, such as east-westward plane or north-southward plane. In other words, the shade can be inclined in a direction toward for example east / west or north / south but not both. This limits the capacity and performance of the large-sized umbrella.[0006]One way to overcome the drawback is manually rotating a ...
