Description

Technical Field

[0001] This application relates to the field of umbrella handle technology, and more specifically to a deformable rotating umbrella handle. Background Technology

[0002] As a widely used tool for sun and rain protection in daily life, the ease of use and comfort of umbrellas directly affect the user experience. The umbrella handle, as the core gripping component of the umbrella, has a structural design and size parameters that are key factors in determining the user experience.

[0003] In existing technologies, to improve user grip stability and comfort, most umbrella handles on the market employ a sufficiently long shaft structure and are designed with a large hand contact area. These types of handles exhibit significant advantages in practical use: firstly, the larger contact area disperses hand grip pressure, reducing fatigue even during prolonged use and greatly improving comfort; secondly, in complex weather conditions such as wind and rain, the combination of a longer handle and a reasonable grip area provides a more stable grip, effectively preventing the umbrella from slipping or wobbling due to external forces, thus ensuring reliability.

[0004] However, the aforementioned traditional umbrella handle design has inherent flaws that are difficult to overcome. Due to its fixed shaft length and large overall size, the handle still occupies a significant amount of space when the umbrella is folded, resulting in a substantial increase in the overall volume. This problem is particularly pronounced when users need to carry an umbrella: for backpacks, handbags, and other carry-on items with limited storage space, the large handle often occupies too much internal space, not only affecting the orderly placement of other items but also potentially preventing the umbrella from fitting completely inside the bag due to the handle's size exceeding the bag's capacity. This causes considerable inconvenience for users in carrying and storing umbrellas, severely impacting the overall user experience.

[0005] To address the technical challenge of existing umbrella handles that struggle to balance grip performance and ease of storage, the inventors have designed a rotating umbrella handle that effectively balances grip comfort and ease of storage. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deformable rotating umbrella handle. Its advantage is that the angle between the umbrella shaft and the umbrella handle can be changed by rotating them, and the shape can be changed by combining the linkage of the umbrella handle's own mechanism, thereby providing users with better grip comfort and convenient storage.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a deformable rotating umbrella handle, comprising an arc-shaped base and an arc-shaped rotating cover coaxially rotatably connected, wherein the outer wall of the arc-shaped base is close to the inner wall of the arc-shaped rotating cover, both of which are arranged in an arc shape along the axial section and can form an internally hollow column structure during relative rotation.

[0008] The arc-shaped base is equipped with a rotating device for mounting and driving the umbrella pole to rotate. The umbrella pole can be rotated and adjusted relative to the arc-shaped base within the range of 0° to 90°.

[0009] Both the arc-shaped base and the arc-shaped rotating cover have a limiting groove on the same end face that matches the maximum outer diameter of the umbrella rod. The limiting groove extends to the end away from the crest of its arc shape, and the maximum outer diameter of the umbrella rod is smaller than the chord length corresponding to the axial section of the arc-shaped base and the arc-shaped rotating cover.

[0010] A rotating component for achieving relative rotation is provided between the arc-shaped base and the arc-shaped rotating cover, as well as a limiting structure for fixing the relative angle between the two at a set position;

[0011] When the umbrella rod is parallel to the length direction of the arc-shaped base and the arc-shaped base and the arc-shaped rotating cover are relatively far apart, the axis of the umbrella rod coincides with the rotation axis of the arc-shaped rotating cover, and the two limiting slots together form a through channel for accommodating and limiting the umbrella rod.

[0012] By adopting the above technical solution, when using the umbrella handle, the umbrella shaft can be rotated along the rotating device until it is parallel to the arc-shaped base. At this time, the axis of the umbrella shaft coincides with the axis of rotation of the arc-shaped rotating cover, and the umbrella shaft abuts against the two limiting slots. Then, the rotating component rotates the arc-shaped base and the arc-shaped rotating cover relative to each other, causing the arc-shaped peaks of their cross-sections to move away from each other. At this time, the limiting structure limits and fixes the arc-shaped base and the arc-shaped rotating cover, and the two limiting slots together form a through channel for accommodating and limiting the umbrella shaft, thereby increasing the contact area between the umbrella handle and the user's hand. It offers good grip comfort. When the umbrella handle needs to be stored, the rotating component rotates the arc-shaped base and the arc-shaped rotating cover relative to each other, bringing their arc-shaped peaks closer together. At this time, the limiting structure limits and fixes the arc-shaped base and the arc-shaped rotating cover. Then, the umbrella shaft is rotated along the rotating device until it is perpendicular to the arc-shaped base. The umbrella ribs are then stored, and the umbrella ribs can be extended and retracted into the cavity formed by the arc-shaped base and the arc-shaped rotating cover. At this time, the umbrella shaft and the umbrella ribs support the cavity formed by the arc-shaped base and the arc-shaped rotating cover to prevent the umbrella shaft from rotating arbitrarily, thereby reducing the space occupied.

[0013] In summary, the above-mentioned components, including the arc-shaped base, arc-shaped rotating cover, rotating device, limiting slot, rotating component, and limiting structure, enable the arc-shaped base and arc-shaped rotating cover to fit together and store the umbrella ribs. When the arc-shaped base and arc-shaped rotating cover are unfolded relative to each other, the umbrella shaft is limited to prevent rotation, and the contact area with the user is increased. This allows the angle of the umbrella shaft and handle to change through rotation, and the shape can be changed by combining the linkage of the umbrella handle's own mechanism, thus providing the user with better grip comfort and convenient storage.

[0014] The present invention is further configured such that: the rotating device includes a rotating seat disposed on an arc-shaped base and a fixed seat rotatably disposed on the rotating seat for fixing the umbrella pole, the rotation angle between the rotating seat and the fixed seat is in the range of 0° to 90°, and when the angle between the rotating seat and the fixed seat is 90°, the umbrella pole is perpendicular to the arc-shaped base and located in the middle of the arc-shaped base, and the fixed seat is abutting against the arc-shaped base.

[0015] By adopting the above technical solution, when it is necessary to rotate the umbrella pole, the fixed seat connected to the umbrella pole can be rotated, and the fixed seat and the rotating seat will rotate relative to each other, so that when the umbrella pole is perpendicular to the arc-shaped base, the angle between the rotating seat and the fixed seat is 90°; when the umbrella pole is parallel to the arc-shaped base, the axis of the umbrella pole coincides with the axis of rotation of the arc-shaped base.

[0016] The present invention is further configured such that: the rotating component includes a first rotating hole disposed at one end of the arc-shaped base away from the corresponding limiting slot and whose axis is coaxial with the rotation axis of the arc-shaped rotating cover; a second rotating hole disposed at one end of the arc-shaped rotating cover away from the corresponding limiting slot and whose axis is coaxial with the first rotating hole; and the same limiting shaft disposed on the first rotating hole and the second rotating hole.

[0017] By adopting the above technical solution, when it is necessary for the arc-shaped base and the arc-shaped rotating cover to rotate relative to each other, a force can be applied to both of them. Under the action of the first rotating hole, the second rotating hole, and the limiting shaft, the arc-shaped base and the arc-shaped rotating cover rotate relative to each other along the limiting shaft, so that the arc-shaped base and the arc-shaped rotating cover rotate relatively stably.

[0018] The present invention is further configured such that: a guide sliding strip is provided on the outer wall of the arc-shaped base and around its rotation axis, and a guide sliding groove is provided on the arc-shaped rotating cover to cooperate with the guide sliding strip.

[0019] By adopting the above technical solution, the setting of guide sliding strips and guide sliding grooves helps to guide and limit the rotation of the arc-shaped base and the arc-shaped rotating cover.

[0020] The present invention is further configured such that: the arc-shaped base has a superior arc-shaped cross section along the axial direction, and the arc-shaped rotating cover has a inferior arc-shaped cross section along the axial direction; the rotating device includes two arc-shaped grooves disposed on the arc surface of the arc-shaped base and located at both ends of its length, and a sliding block disposed on the arc-shaped rotating cover with a T-shaped cross section and sliding in cooperation with the corresponding arc-shaped groove; the two arc-shaped grooves extend rotatably along the axis of the arc-shaped base to either side.

[0021] By adopting the above technical solution, when it is necessary for the arc-shaped base and the arc-shaped rotating cover to rotate relative to each other, a force can be applied to both of them. The arc-shaped base and the arc-shaped rotating cover rotate during the relative sliding process of the sliding block and the arc-shaped groove. The sliding block rotates along the arc-shaped groove around the axis of rotation between the arc-shaped base and the arc-shaped rotating cover, thereby making the arc-shaped base and the arc-shaped rotating cover rotate relative to each other.

[0022] The present invention is further configured such that: the limiting structure includes two elastic protrusions disposed on the outer wall of the arc-shaped base and arranged around its axis, and a snap-fit ​​groove disposed on the inner wall of the arc-shaped rotating cover and engaged with any of the elastic protrusions.

[0023] By adopting the above technical solution, when the axial section peaks of the arc-shaped base and the arc-shaped rotating cover are relatively far apart, the corresponding elastic protrusion on the outer wall of the arc-shaped base cooperates with the locking groove on the inner wall of the arc-shaped rotating cover to limit the arc-shaped base and the arc-shaped rotating cover; when the axial section peaks of the arc-shaped base and the arc-shaped rotating cover are relatively close, the corresponding elastic protrusion on the outer wall of the arc-shaped base cooperates with the locking groove on the inner wall of the arc-shaped rotating cover to limit the arc-shaped base and the arc-shaped rotating cover. Thus, through the relative cooperation of the two elastic protrusions and the locking groove, the limiting of the arc-shaped base and the arc-shaped rotating cover during rotation can be achieved.

[0024] In summary, this utility model has the following advantages:

[0025] By using an arc-shaped base, an arc-shaped rotating cover, a rotating device, a limiting slot, a rotating component, and a limiting structure, the arc-shaped base and the arc-shaped rotating cover can be placed together to store the umbrella ribs. When the arc-shaped base and the arc-shaped rotating cover are unfolded relative to each other, the umbrella pole is limited to prevent it from rotating, and the contact area with the user is increased. Thus, the angle between the umbrella pole and the handle can be changed by rotating the umbrella pole and the handle. Combined with the linkage of the handle's own mechanism, the shape can be changed, so that the user can have better grip comfort and convenient storage. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1, as Figure 1 , 2 As shown, a deformable rotating umbrella handle includes an arc-shaped base 1 and an arc-shaped rotating cover 2 coaxially rotatably connected. The outer wall of the arc-shaped base 1 is close to the inner wall of the arc-shaped rotating cover 2. Both are arranged in an arc shape along the axial section, and the arc-shaped base 1 and the arc-shaped rotating cover 2 are arranged in a superior arc shape along the axial section, and can form a hollow column structure during relative rotation.

[0036] The arc-shaped base 1 is equipped with a rotating device for installing and driving the umbrella pole 16 to rotate. The umbrella pole 16 can be rotated and adjusted relative to the arc-shaped base 1 within the range of 0° to 90°.

[0037] Both the arc-shaped base 1 and the arc-shaped rotating cover 2 have a limiting groove 3 on the same end face that matches the maximum outer diameter of the umbrella rod 16. The limiting groove 3 extends to the end away from the crest of its arc shape, and the maximum outer diameter of the umbrella rod 16 is smaller than the chord length corresponding to the arc-shaped base 1 and the arc-shaped rotating axial section.

[0038] A rotating component for achieving relative rotation is provided between the arc-shaped base 1 and the arc-shaped rotating cover 2, and a limiting structure for fixing the relative angle between the two at a set position;

[0039] When the umbrella rod 16 is parallel to the length direction of the arc-shaped base 1 and the arc-shaped base 1 and the arc-shaped rotating cover 2 are relatively far apart, the axis of the umbrella rod 16 coincides with the rotation axis of the arc-shaped rotating cover 2, and the two limiting slots 3 together form a through channel for accommodating and limiting the umbrella rod 16.

[0040] like Figure 1 , 3 As shown, the rotating device includes a rotating seat 4 fixed on an arc-shaped base 1 and a fixed seat 5 rotatably mounted on the rotating seat 4 for fixing the umbrella pole 16. The fixed seat 5 has a T-shaped cross section extending in the direction of rotation of the rotating seat 4. The umbrella pole 16 is fixedly mounted on the fixed seat 5. The rotation angle between the rotating seat 4 and the fixed seat 5 is in the range of 0° to 90°. When the angle between the rotating seat 4 and the fixed seat 5 is 90°, the umbrella pole 16 is perpendicular to the arc-shaped base 1 and located in the middle of the arc-shaped base 1, and the fixed seat 5 is pressed against the arc-shaped base 1.

[0041] When it is necessary to rotate the umbrella pole 16, the fixed seat 5 connected to the umbrella pole 16 can be rotated, and the fixed seat 5 and the rotating seat 4 will rotate relative to each other, so that when the umbrella pole 16 is perpendicular to the arc-shaped base 1, the angle between the rotating seat 4 and the fixed seat 5 is 90°; when the umbrella pole 16 is parallel to the arc-shaped base 1, the axis of the umbrella pole 16 coincides with the rotation axis of the arc-shaped base 1.

[0042] like Figure 3 , 4 As shown, the rotating component includes a first rotating hole 6 opened at the end of the arc-shaped base 1 away from the corresponding limiting slot 3 and whose axis is coaxial with the rotation axis of the arc-shaped rotating cover 2, a second rotating hole 7 opened at the end of the arc-shaped rotating cover 2 away from the corresponding limiting slot 3 and whose axis is coaxial with the first rotating hole 6, and the same limiting shaft 8 installed on the first rotating hole 6 and the second rotating hole 7, wherein the limiting shaft 8 is an elastic stepped shaft with high sides and low middle, and the elastic stepped shaft has a deformation groove 9 opened at the end facing the limiting slot 3. When it is necessary for the arc-shaped base 1 and the arc-shaped rotating cover 2 to rotate relative to each other, a force can be applied to both. Under the action of the first rotating hole 6, the second rotating hole 7, and the limiting shaft 8, the arc-shaped base 1 and the arc-shaped rotating cover 2 rotate relative to each other, so that the arc-shaped base 1 and the arc-shaped rotating cover 2 rotate relatively stably. When the limiting shaft 8 is installed on the first rotating hole 6 and the second rotating hole 7, the end with the deformation groove 9 can be squeezed into the first rotating hole 6 and the second rotating hole 7. During the squeezing process, the limiting shaft 8 deforms through the deformation groove 9. When the first rotating hole 6 and the second rotating hole 7 are located in the middle of the limiting shaft 8, the end of the limiting shaft 8 located in the deformation groove 9 returns to its original shape through the restoring force, thereby limiting the first rotating hole 6 and the second rotating hole 7.

[0043] It is worth mentioning that the arc-shaped base 1 has a guide sliding strip 10 extending around the outer wall of the limiting slot 3 and along its rotation axis. The arc-shaped rotating cover 2 has a guide sliding groove 11 that cooperates with the guide sliding strip 10. The setting of the guide sliding strip 10 and the guide sliding groove 11 helps to guide and limit the arc-shaped base 1 and the arc-shaped rotating cover 2 during rotation.

[0044] Furthermore, such as Figure 2 , 3 As shown, the limiting structure includes two elastic protrusions 12 fixed to the outer wall of the arc-shaped base 1 and arranged around its axis, and a locking groove 13 formed on the inner wall of the arc-shaped rotating cover 2 and engaging with either elastic protrusion 12. When the axial cross-sectional peaks of the arc-shaped base 1 and the arc-shaped rotating cover 2 are relatively far apart, the corresponding elastic protrusion 12 on the outer wall of the arc-shaped base 1 engages with the locking groove 13 on the inner wall of the arc-shaped rotating cover 2 to limit the arc-shaped base 1 and the arc-shaped rotating cover 2. When the axial cross-sectional peaks of the arc-shaped base 1 and the arc-shaped rotating cover 2 are relatively close, the corresponding elastic protrusion 12 on the outer wall of the arc-shaped base 1 engages with the locking groove 13 on the inner wall of the arc-shaped rotating cover 2 to limit the arc-shaped base 1 and the arc-shaped rotating cover 2. Thus, through the relative engagement of the two elastic protrusions 12 and the locking groove 13, the limiting of the arc-shaped base 1 and the arc-shaped rotating cover 2 during rotation can be achieved.

[0045] The working process and beneficial effects of this utility model are as follows:

[0046] When using the umbrella handle, the umbrella shaft 16 can be rotated along the rotating device until it is parallel to the arc-shaped base 1. At this time, the axis of the umbrella shaft 16 coincides with the rotation axis of the arc-shaped rotating cover 2, and the umbrella shaft 16 abuts against the two limiting slots 3. Then, the arc-shaped base 1 and the arc-shaped rotating cover 2 are rotated relative to each other by the rotating component, so that the arc-shaped peaks of the two are far apart. At this time, the limiting structure limits and fixes the arc-shaped base 1 and the arc-shaped rotating cover 2, and the two limiting slots 3 together form a through channel for accommodating and limiting the umbrella shaft 16, which increases the contact area between the umbrella handle and the user's hand, making the grip more comfortable. It is better; when the umbrella handle needs to be stored, the arc-shaped base 1 and the arc-shaped rotating cover 2 are rotated relative to each other by the rotating component, so that the arc-shaped peaks of the two are relatively close. At this time, the limiting structure limits and fixes the arc-shaped base 1 and the arc-shaped rotating cover 2. Then, the umbrella pole 16 is rotated along the rotating device until it is perpendicular to the arc-shaped base 1. The umbrella ribs are then stored, and the umbrella ribs can be extended and retracted into the cavity formed by the arc-shaped base 1 and the arc-shaped rotating cover 2. At this time, the umbrella pole 16 and the umbrella ribs support the cavity formed by the arc-shaped base 1 and the arc-shaped rotating cover 2 to prevent the umbrella pole 16 from rotating arbitrarily, thereby reducing the space occupied.

[0047] In summary, the above-mentioned components, including the arc-shaped base 1, the arc-shaped rotating cover 2, the rotating device, the limiting slot 3, the rotating component, and the limiting structure, enable the arc-shaped base 1 and the arc-shaped rotating cover 2 to be placed together and the umbrella ribs to be stored. When the arc-shaped base 1 and the arc-shaped rotating cover 2 are unfolded relative to each other, the umbrella pole 16 is limited to prevent it from rotating, and the contact area with the user is increased. This allows the angle between the umbrella pole 16 and the umbrella handle to be changed by rotation, and the shape can be changed by the linkage of the umbrella handle's own mechanism, so as to provide the user with better grip comfort and convenient storage.

[0048] The differences from the rotating component in Embodiment 1 are as follows: Figure 5 , 6 As shown in Figure 7, a modified rotating umbrella handle of this embodiment 2 also includes an arc-shaped base 1 with a superior arc-shaped cross section along the axial direction, and an arc-shaped rotating cover 2 with a inferior arc-shaped cross section along the axial direction. The rotating device includes two arc-shaped grooves 14 opened on the arc surface of the arc-shaped base 1 and located at both ends of its length, and a sliding block 15 fixed on the arc-shaped rotating cover 2 with a T-shaped cross section and sliding in cooperation with the corresponding arc-shaped grooves 14. The two arc-shaped grooves 14 rotate and extend to either side along the axis of the arc-shaped base 1.

[0049] When it is necessary for the arc-shaped base 1 and the arc-shaped rotating cover 2 to rotate relative to each other, a force can be applied to both of them. The arc-shaped base 1 and the arc-shaped rotating cover 2 rotate during the relative sliding process of the sliding block 15 and the arc-shaped groove 14. The sliding block 15 rotates along the arc-shaped groove 14 around the axis of rotation between the arc-shaped base 1 and the arc-shaped rotating cover 2, thereby causing the arc-shaped base 1 and the arc-shaped rotating cover 2 to rotate relative to each other.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
