[0066] Embodiments of the present application will be described in more detail with reference to the drawings. Although certain embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present application will be more thoroughly understood. It is to be understood that the drawings and embodiments of the present application are for illustrative purposes only and should not be construed as limiting the scope of the present application.

[0067] It should also be noted that, for the sake of brevity, only the portions of the drawings that are necessary for the understanding of the present application have been shown. The embodiments and features of the present application can be combined with each other, without conflict, in the case of no conflict.

[0068] It should be noted that the terms “first”, “second”, and the like used in the present application are merely used to distinguish different devices, modules, or units, and do not imply the order or interdependence of the functions performed by these devices, modules, or units.

[0069] It should be noted that the terms “one”, “multiple” used in the present application are illustrative and not restrictive, and those skilled in the art should understand that, unless otherwise explicitly stated in the context, it should be understood as “one or more”.

[0070] The present application will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0071] Reference Figures 1 to 7As shown, some embodiments of the present application provide an umbrella adjusting device 100, which can be integrated on an umbrella for example, and used to adjust the inclination angle of the umbrella ribs and umbrella cloth relative to the umbrella handle, and to lock the position of the umbrella ribs and umbrella cloth relative to the umbrella handle after the inclination angle is adjusted.

[0072] Referring to Figure 1 and Figure 2 As shown, the umbrella adjusting device 100 comprises a base 110, a first movable member 120, a second movable member 130, and an adjusting member 140.

[0073] The base 110 is adapted to be connected to the umbrella handle of an umbrella, which is referred to as the part of the umbrella for a user to hold. The base 110 is fixed to the umbrella handle by means of, for example, threaded connection, interference fit, etc.

[0074] The first movable member 120 is rotationally connected to the base 110 and is adapted to be connected to the umbrella ribs of an umbrella, so that the umbrella ribs can rotate relative to the base 110, thereby adjusting the inclination angle of the umbrella ribs relative to the umbrella handle.

[0075] It should be noted that although the function of the umbrella adjusting device 100 is described in the manner of adjusting the inclination angle of the umbrella ribs relative to the umbrella handle, in actual application, the umbrella ribs and the umbrella cloth can not necessarily be directly connected to the first movable member 120, and correspondingly, the base 110 can not necessarily be directly connected to the umbrella handle. For example, the first movable member 120 can be fixed to a first rod, and each umbrella rib can be hingedly connected to a slider, which is then slidably arranged on the first rod to achieve the connection of the umbrella ribs to the first movable member 120. For another example, the umbrella handle can be fixed to one end of a second rod, and the other end of the rod is fixed to the base 110 to achieve the connection of the umbrella handle to the base 110.

[0076] The second movable member 130 is slidably arranged on the base 110 in a first direction X1 to have at least a locked position and an unlocked position relative to the base 110. When the second movable member 130 is in the locked position, it engages with the first movable member 120 to lock the relative position of the first movable member 120 and the base 110, and when the second movable member 130 is in the unlocked position, it avoids the first movable member 120 to unlock the first movable member 120, i.e., when the second movable member 130 is in the unlocked position, it disengages with the first movable member 120. The engagement between the first movable member 120 and the second movable member 130 is, for example, in the form of a structure similar to gear engagement. When the first movable member 120 is rotated, the first movable member 120 rotates and drives the second movable member 130 to move from the locked position to the unlocked position, thereby realizing the rotation of the first movable member 120. Thus, by locking the second movable member 130 in the locked position, the rotation of the second movable member 130 relative to the base 110 can be prevented.

[0077] To lock the second movable component 130 in the locked position, and to enable the second movable component 130 to move from the locked position to the unlocked position for unlocking purposes, refer to... Figure 1 and Figure 3 As shown, the umbrella adjustment device 100 is provided with an adjustment member 140, which is rotatably mounted on the base 110 so as to have at least a stop position and a clearance position relative to the base 110; wherein, the adjustment member 140 is provided with a stop surface 141; when the adjustment member 140 is in the stop position, the stop surface 141 is adapted to stop the second movable member 130 to prevent the second movable member 130 from moving to the unlock position; when the adjustment member 140 is in the clearance position, the stop surface 141 is adapted to allow the second movable member 130 to move from the locked position to the unlock position.

[0078] By adopting the above solution, the adjusting member 140 is rotatably set on the base 110, and the stop surface 141 is used to block the sliding of the second movable member 130 to achieve locking. The umbrella rib is locked and unlocked on the base 110 by rotating the adjusting member 140 so that the stop surface 141 avoids the sliding of the second movable member 130. Compared with the threaded locking method in the prior art, the operation of locking and unlocking the adjusting member 140 does not require rotating the adjusting member 140 for many turns. It is only necessary to rotate the stop surface 141 to a specific position to achieve the function. Therefore, the operation is more convenient while ensuring stable locking of the umbrella rib.

[0079] In some embodiments, refer to Figure 1 and Figure 4 As shown, the base 110 is provided with an abutment surface 111. The abutment surface 111 is located at the end of the adjusting member 140 away from the second movable member 130 along the first direction X1. When the second movable member 130 is in the locked position and the adjusting member 140 is in the stop position, both ends of the adjusting member 140 along the first direction X1 abut against the second movable member 130 and the abutment surface 111, respectively. Specifically, the stop surface 141 is formed at the end of the adjusting member 140 along the first direction X1 near the abutment surface 111. When the second movable member 130 is in the locked position and the adjusting member 140 is in the stop position, the abutment surface 111 and the stop surface 141 abut against each other, and the end of the adjusting member 140 near the second movable member 130 can be configured to abut against the second movable member 130, thereby preventing the second movable member 130 from moving along the first direction X1 and holding the second movable member 130 in the locked position, thus preventing the first movable member 120 from rotating relative to the base 110.

[0080] As an example of a specific solution, refer to Figure 3As shown, the adjusting member 140 is further provided with a limiting protrusion 142. The limiting protrusion 142 is arranged at an end of the adjusting member 140 along the first direction X1, and more specifically, the limiting protrusion 142 is formed at an end of the adjusting member 140 close to the abutting surface 111 along the first direction X1. The stop surface 141 is configured as an inclined surface 142a on the limiting protrusion; when the adjusting member 140 is located at the stop position, the inclined surface 142a is in surface contact with the abutting surface 111. The inclined surface 142a in surface contact with the abutting surface 111 ensures the structural strength of the matching structure between the adjusting member 140 and the base 110, so that after the first movable member 120 is locked on the base 110, the umbrella ribs and the umbrella cloth can be stably installed on the umbrella handle, avoiding shaking of the umbrella ribs and the umbrella cloth.

[0081] As an example of a specific solution, reference is made to Figure 4 As shown, the base 110 is further provided with a limiting recess 112. The limiting recess 112 is open at an end close to the adjusting member 140 along the first direction X1 for the limiting protrusion 142 to be inserted. The abutting surface 111 is configured as an inclined inner wall 112a of the limiting recess 112. When the adjusting member 140 is located at the stop position, the inclined surface 142a is in surface contact with the inclined inner wall 112a. Compared with the abutting matching between the plane and the plane, the matching between the inclined surface 142a and the inclined inner wall 112a is conducive to production, reduces the possibility that the abutting surface 111 and the stop surface 141 do not normally abut when locking the first movable member 120 due to machining errors and other reasons, thereby ensuring the locking effect on the first movable member 120 and further reducing the possibility of shaking of the umbrella ribs relative to the umbrella handle during use.

[0082] In some embodiments, reference is made to Figure 3 As shown, the limiting protrusion 142 is provided with a limiting end surface 142b. Correspondingly, reference is made to Figure 4 As shown, the groove wall of the limiting recess 112 includes a limiting wall surface 112b. When the adjusting member 140 is located at the avoidance position, the limiting end surface 142b is in abutment with the limiting wall surface 112b to limit the rotation of the adjusting member 140. In a more specific solution, the limiting end surface 142b and the limiting wall surface 112b may, for example, be planes with normal lines inclined to the first direction X1. Through the matching of the limiting end surface 142b and the limiting wall surface 112b, the angle through which the adjusting member 140 can rotate relative to the base 110 is limited, and when the adjusting member 140 is rotated, the user is fed back with a force through the abutment of the limiting end surface 142b and the limiting wall surface 112b, which facilitates prompting the user that the adjusting member 140 has been located at the avoidance position relative to the base 110. The matching of the inclined surface 142a and the inclined inner wall 112a can prompt the user that the adjusting member 140 has been located at the stop position relative to the base 110.

[0083] In some embodiments, reference is made to Figure 2 and Figure 7As shown, the umbrella adjusting device 100 further comprises a reset spring 150. The reset spring 150 is adapted to provide an elastic force to the second movable member 130 to make it tend to be in the locked position. The reset spring 150 is arranged to provide a pre-tightening force to the second movable member 130, so that when the adjusting member 140 is in the avoiding position, the reset spring 150 can make the second movable member 130, avoiding the umbrella ribs from loosening.

[0084] As a specific solution, in some embodiments, referring to Figure 7 As shown, the adjusting member 140 is arranged to slide along the first direction X1 on the base 110. The reset spring 150 is arranged between the adjusting member 140 and the base 110 to make the adjusting member 140 tend to keep in contact with the second movable member 130. Thus, the reset spring 150 directly applies an elastic force to the adjusting member 140, the adjusting member 140 makes the second movable member 130 have a tendency to reset to the locked position by transmitting the acting force, and when adjusting the inclination angle of the first movable member 120 relative to the base 110, the adjusting member 140 moves along the first direction X1 synchronously with the second movable member 130, avoiding the relative movement between the adjusting member 140 and the second movable member 130 in the first direction X1, which can avoid the user's limbs being clamped when they are located between the second movable member 130 and the adjusting member 140.

[0085] As an exemplary description of the specific structure of the realization of the fitting between the first movable member 120 and the second movable member 130, referring to Figure 5 and Figure 6 As shown, the first movable member 120 is provided with a first tooth part 121, and correspondingly, the second movable member 130 is provided with a second tooth part 131.

[0086] In which, when the second movable member 130 is in the locked position, the first tooth part 121 and the second tooth part 131 are fitted with each other. In a more specific solution, the first tooth part 121 can contain a plurality of meshing teeth 122 distributed circumferentially on the first movable member 120, and the second tooth part 131 can contain a plurality of tooth grooves 132 distributed circumferentially on the second movable member 130.

[0087] Referring to Figure 5 and Figure 6As shown, when the second movable part 130 is in the locking position, the at least one engagement tooth 122 is embedded in one of the tooth grooves 132, and when the adjusting part 140 is in the stop position, the engagement tooth 122 cannot be disengaged from the tooth groove 132, so that the first movable part 120 is fixed on the base 110, realizing the locking of the umbrella rib on the umbrella handle. When the adjusting part 140 is in the avoiding position, the user can, for example, pull the first movable part 120 to make the at least one engagement tooth 122 apply a force to the groove wall of the at least one tooth groove 132, guiding the second movable part 130 to move in the first direction X1 to the unlocking position, and the engagement tooth 122 gradually disengages from the tooth groove 132. When the first movable part 120 continues to rotate, the adjacent engagement tooth 122 of the engagement tooth 122 is embedded in the tooth groove 132, realizing the adjustment of the inclination angle of the first movable part 120 relative to the base 110. Then, by rotating the adjusting part 140 to the stop position, the movement of the second movable part 130 in the first direction X1 is prevented, that is, the position of the first movable part 120 relative to the base 110 is locked.

[0088] In some embodiments, with reference to Figure 6 As shown, the first movable part 120 is further provided with an avoiding groove 123. The avoiding groove 123 is for accommodating at least a part of the second tooth part 131, and the avoiding groove 123 is formed at one end of the first tooth part 121 away from the second tooth part 131. The avoiding groove 123 can accommodate at least a part of the second movable part 130 when the first movable part 120 rotates, so that the first movable part 120 can rotate a larger angle relative to the base 110.

[0089] The application can realize the locking or unlocking of the first movable part 120 by abutting or separating the stop surface 141 from the base 110. When the first movable part 120 is unlocked, a gap is formed between the stop surface 141 and the base 110, with reference to Figure 8 and Figure 9 As shown, in some embodiments of the application, the adjusting part 140 can be further provided with a shielding part 143. The shielding part 143 is located at the end of the adjusting part 140 close to the base 110 in the first direction X1. The shielding part 143 surrounds the periphery of the limiting protrusion 142, so that the shielding part 143 shields the gap formed between the stop surface 141 and the base 110, and the gap is not exposed to the outside. Thus, the shielding part 143 can separate the stop surface 141 from the user, avoiding the user's limbs from entering the gap between the stop surface 141 and the base 110 during the rotation of the adjusting part 140.

[0090] The adjusting member 140 rotates relative to the base 110 to lock or unlock the first movable member 120. In order to determine the relative position of the adjusting member 140 and the base 110, the adjusting member 140 is provided with a first positioning portion 144. Correspondingly, at least one of the base 110 and the second movable member 130 is provided with a second positioning portion 113. The first positioning portion 144 is formed on the surface of the adjusting member 140, and the second positioning portion 113 is formed on the surface of the base 110 and / or the second movable member 130. When the adjusting member 140 rotates relative to the base 110, the first positioning portion 144 changes the orientation relative to the second positioning portion 113.

[0091] As an example of the specific implementation, refer to Figure 9 As shown in the figure, the first positioning portion 144 is, for example, a paint pattern arranged on the surface of the adjusting member 140, or a protrusion, a groove, etc. formed on the surface of the adjusting member 140. Similarly, the second positioning portion 113 can also be a paint pattern arranged on the surface of the base 110, or a protrusion, a groove, etc. formed on the surface of the base 110. When the adjusting member 140 rotates relative to the base 110, the first positioning portion 144 rotates relative to the second positioning portion 113.

[0092] In this way, the user can determine whether the first movable member 120 is locked or unlocked by observing the relative position of the first positioning portion 144 and the second positioning portion 113, which is convenient for the user. It can be understood that when the adjusting member 140 is provided with the aforementioned shielding portion 143, the user cannot directly observe the relative position of the stop surface 141 and the base 110, but the cooperation of the first positioning portion 144 and the second positioning portion 113 can make up for this deficiency, so as to further facilitate the user.

[0093] Refer to Figure 10 As shown in the figure, some embodiments of the present application also provide an umbrella 10 comprising the umbrella adjusting device 100 described above. The umbrella 10 has all the beneficial effects of the umbrella adjusting device 100 described above, which will not be repeated here. The specific connection form between the umbrella cloth, the umbrella rib, the umbrella handle, etc. of the umbrella 10 and the umbrella adjusting device 100 is not the focus of the improvement of the present application, and the person skilled in the art can flexibly set it according to the actual needs, which is not limited in the present application.

[0094] The above description is only some of the preferred embodiments of the present application and the explanation of the technical principles applied. It should be understood by those skilled in the art that the scope of the application involved in the embodiments of the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and also covers other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
