Description

Technical Field

[0001] This utility model belongs to the field of outdoor umbrella technology, and specifically relates to a cantilevered oblique umbrella that is easy to operate. Background Technology

[0002] Cantilevered slanted umbrellas, also known as side-standing Roman umbrellas, have side posts and an umbrella canopy. Opening and closing them typically requires the user to manually push the handle from the bottom up, then crank the umbrella cord to open or close the umbrella. This makes operation relatively complex, especially for Roman umbrellas with larger canopies, which require considerable force to open and close, affecting user comfort. Furthermore, the relatively fixed height of the upper umbrella tray means that the longer umbrella ribs can easily touch objects underneath the umbrella during opening and closing, restricting operation and also affecting user convenience. Utility Model Content

[0003] The purpose of this utility model is to propose an easy-to-operate cantilevered angled umbrella. By setting up a two-section side column with adjustable height, and an opening and closing hinge assembly that slides relative to the side column, the umbrella can be opened and closed using only the umbrella rope, without the need for additional pushing. Moreover, during the opening and closing process, the end of the umbrella rib is unlikely to touch the items under the umbrella. It has the characteristics of smooth opening and closing of the umbrella canopy and convenient operation.

[0004] This utility model is achieved through the following technical solution: This utility model proposes an easy-to-operate cantilevered angled umbrella, including an umbrella frame assembly, a side post assembly, and an umbrella base assembly. The umbrella frame assembly includes a rib assembly, a fixed umbrella disc, a movable umbrella disc, and an opening / closing hinge assembly that are connected in a mating manner. The opening / closing hinge assembly includes a main support rod and a movable umbrella disc support rod that are X-shaped and cross-fitted. The upper end of the main support rod is hinged to the fixed umbrella disc, and the lower end is hinged to a sliding seat. The side post assembly includes an upper side post assembly, a lower side post that is slidably connected to the upper side post assembly, a traction assembly, and an elastic element. The top of the upper side post assembly is provided with a hinge seat, and the hinge... The seat is hinged to the moving umbrella disc support rod, and the lower column has a sliding groove in which the sliding seat is slidably disposed. The traction assembly includes an opening and closing winding device on the lower column, an umbrella cord, a first pulley, a second pulley and an umbrella cord fixing member on the hinged seat, and a third pulley on the sliding seat. One end of the umbrella cord is wound around the opening and closing winding device, and the other end passes through the first pulley, the second pulley and the third pulley in sequence before being fixed to the umbrella cord fixing member. The lower end of the elastic element is fixedly connected to the opening and closing winding device, and the upper end is fixedly connected to the bottom of the upper column assembly.

[0005] Based on the above technical solutions, the main support rod in the opening and closing hinge assembly is slidably mounted on the lower side post, and the parasol rope of the traction assembly is fixed after passing over the third pulley on the sliding seat. This directly controls the relative position change of the fixed umbrella disc and the moving umbrella disc, driving the umbrella frame assembly to open and close. There is no need to simultaneously control the opening and closing of the opening and closing hinge assembly and the winding of the parasol rope. Moreover, the third pulley moves with the sliding seat, achieving the labor-saving effect of the moving pulley and improving the stability of the parasol rope control. Furthermore, by setting the side post as a combination of the upper side post assembly and the lower side post with adjustable height, the height of the fixed umbrella disc decreases after the umbrella is opened to ensure the shading area. When the umbrella is closed, the fixed umbrella disc is raised, and the end of the umbrella ribs is away from items under the umbrella, reducing operational interference factors. The whole system has the characteristics of stable opening and closing control, labor-saving operation, and simplicity. Preferably, the upper column assembly includes an outer cover tube, an upper column, and a guide tube nested sequentially from the outside in. The inner diameter of the outer cover tube is larger than the outer diameters of the upper and lower columns. The hinge seat is simultaneously fixed to the top of the outer cover tube, the upper column, and the guide tube. The first pulley is correspondingly arranged with the inner cavity of the upper column. The second pulley, the paracord fixing member, and the third pulley are correspondingly arranged with respect to the gap between the upper column and the outer cover tube. The upper end of the guide tube is embedded inside the upper column, and the lower end is embedded inside the lower column. Guide strips are provided inside the upper and lower columns, and guide grooves that cooperate with the guide strips are provided outside the guide tube. This design, through the setting of the outer cover tube, ensures that the two ends of the paracord passing through the hinge seat are located on the inner and outer sides of the upper column, while also allowing the paracord of the traction sliding seat to be internally located, which is beneficial for the independence and protection of the paracords. Furthermore, through the cooperation between the guide tube and the upper and lower columns, stable relative sliding between the upper and lower columns is achieved.

[0006] Furthermore, the guide tube is provided with three sets of pulleys. One set is vertically located on the side wall at the lower end of the guide tube and is tumblingly connected to the side wall of the lower column. The other two sets are respectively located in the guide groove and are tumblingly connected to the guide strip. The purpose of this design is to achieve a tumbling connection between the guide tube and the lower column through multiple pulley sets, reduce the lifting resistance of the upper column, and make the compression and release of the paracord control elastic element more effortless.

[0007] Preferably, the opening and closing winding device includes a set of opposing guard plates and a paracord self-locking component located at the lower end of the guard plates. The guard plates are centrally located relative to the inner cavity of the lower side post. The lower end of the elastic element is fixed to the upper end of the guard plate, and the lower end of the guard plate is fixed to the lower side post. This design, by limiting the position of the guard plates, ensures that the paracord self-locking component and the elastic element are centrally located. This facilitates the smooth vertical lifting and lowering of the upper side post, and also helps to avoid friction between the paracord and components such as the lower side post and the upper side post assembly, preventing paracord wear and reducing opening and closing resistance.

[0008] Furthermore, the opening and closing winding device also includes a guide rope assembly, which is located above the paracord self-locking member. The guide rope assembly includes a guide wheel bracket and a guide wheel group mounted thereon. The guide wheel bracket is fixed to the protective plate. The guide wheel group consists of a pair of parallel guide wheels with their outer edges touching. The paracord passes through the gap between the guide wheels and then winds around the paracord self-locking member. This design controls the paracord to be in a relatively fixed position when it is wound or released by the paracord self-locking member, thereby further preventing paracord friction and avoiding the paracord from slipping off the first pulley when closing the umbrella.

[0009] Furthermore, the paracord self-locking component is connected to the guard plate via a pair of bearings. This design facilitates the smooth rotation of the paracord self-locking component, making the process of tightening or releasing the paracord easier.

[0010] Preferably, the opening and closing hinge assembly further includes a hinge connecting rod seat, the main support rods are a pair, the hinge connecting rod seat is embedded between the main support rods and its middle part is fixed to the middle part of the main support rod by a hinge pin, and the movable umbrella disc support rods are two pairs, which are respectively fixed to both ends of the hinge connecting rod seat by fixing pins. This design helps to increase the structural strength of the opening and closing hinge assembly and improve the stability of the umbrella frame assembly opening and closing.

[0011] Preferably, the elastic element is a compression spring or a gas spring.

[0012] Preferably, the lower side post and the umbrella frame assembly are connected by a rotating assembly. The rotating assembly includes a rotating seat and a locking assembly. The rotating seat includes a rotating central shaft, a support tube, an upper bearing seat, ball bearings, a lower bearing seat, and a lower support seat. The lower end of the rotating central shaft is fixed to the lower bearing seat, and the upper end is connected to the lower side post through the locking assembly. The support tube is sleeved outside the rotating central shaft and fixed to the lower side post. The lower end of the support tube is fixed to the lower support seat. The lower support seat is rotatably connected to the upper and lower bearing seats through ball bearings. The lower bearing seat is fixed to the umbrella frame assembly. The locking assembly is used to lock or unlock the lower side post and the rotating central shaft. This design allows the side post to rotate at any angle through the rotating assembly, so as to adjust the position of the umbrella frame assembly arbitrarily.

[0013] Furthermore, the rotating base also includes an upper support base, which is rotatably connected to the top of the rotating central shaft and fixedly engaged with the lower side column. The locking assembly includes an anti-rotation groove disposed around the upper end of the rotating central shaft and a rotary switch disposed on the lower side column. The rotary switch includes a switch base, a locking pin that engages with the anti-rotation groove, and an operating handle. The locking pin is fixed to the upper end of the operating handle, the operating handle is rotatably connected to the switch base, and the switch base is fixedly connected to the upper support base. This design improves the smoothness and stability of the side column rotation through the upper support base, and achieves rapid locking and unlocking of the side column assembly rotation function through the cooperation of the rotary switch and the anti-rotation groove.

[0014] Beneficial effects One of the above technical solutions has the following advantages or beneficial effects: 1) By using an X-shaped cross-fitting opening and closing hinge assembly, with its main support rod slidably mounted on the lower side post, and fixing the parasol rope of the traction assembly after passing it sequentially around the first pulley, the second pulley on the hinge seat, and the third pulley on the sliding seat, the movement of the sliding seat is directly controlled by the parasol rope, thereby controlling the relative position change between the fixed and movable parasol discs and driving the opening and closing of the umbrella frame assembly. There is no need to simultaneously control the opening and closing of the opening and closing hinge assembly and the winding of the parasol rope. The third pulley moves with the sliding seat, which also realizes the labor-saving effect of the movable pulley and improves the stability of the parasol rope control. At the same time, in combination with the upper side post assembly and the lower side post with adjustable height, the height of the fixed parasol disc decreases after the umbrella is opened to ensure the sunshade area, and the fixed parasol disc rises when the umbrella is closed, so that the end of the umbrella ribs is away from the items under the umbrella, reducing operational interference factors. This cantilevered angled umbrella has the characteristics of stable opening and closing control, labor-saving operation, and simplicity.

[0015] 2) By setting a protective plate in the opening and closing winding device that is centered relative to the inner cavity of the lower column, it serves as a support structure for the paracord self-locking component and elastic element, thus centered the paracord self-locking component and elastic element. A guide rope assembly is set above the paracord self-locking component, which enables the upper column to rise and fall smoothly vertically, reduces opening and closing resistance, and simultaneously enables the positioning, winding and releasing of the paracord. This avoids friction between the paracord and components such as the lower column and upper column assembly, preventing paracord wear and additional resistance. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0018] like Figure 1 As shown, this utility model provides an easy-to-operate cantilevered angled umbrella, including an umbrella frame assembly 1, a side post assembly 2, and an umbrella base assembly 3. The umbrella frame assembly 1 includes a rib assembly 11, a fixed umbrella disc 12, a movable umbrella disc 13, and an opening / closing hinge assembly 14 that are connected in a mating manner. The opening / closing hinge assembly 14 includes a main support rod 141 and a movable umbrella disc support rod 142 that are X-shaped and cross-fitted. The upper end of the main support rod 141 is hinged to the fixed umbrella disc 12, and the lower end is hinged to a sliding seat 24. Preferably, as shown... Figure 2As shown, the opening and closing hinge assembly 14 also includes a hinge link seat 143. The main support rods 141 are a pair, and the hinge link seat 143 is embedded between the main support rods 141, with its middle part fixed to the middle part of the main support rods 141 by a hinge pin 144. The movable umbrella disc support rods 142 are two pairs, respectively fixed to both ends of the hinge link seat 143 by fixing pins 145, so as to strengthen the structural strength of the main support rods 141 and the movable umbrella disc support rods 142, adapt to the smooth opening and closing of a larger umbrella surface, and at the same time, the hinge link seat 143 reduces the frictional resistance between the main support rods 141 and the movable umbrella disc support rods 142, thereby reducing the opening and closing resistance.

[0019] like Figures 3-7 As shown, the side post assembly 2 includes an upper side post assembly 22, a lower side post 23 slidably connected to the upper side post assembly 22, a traction assembly 25, and an elastic element 26. Figure 3 As shown, the upper side column assembly 22 includes an outer cover tube 221, an upper side column 222, and a guide tube 223 nested sequentially from the outside in. The inner diameter of the outer cover tube 221 is larger than the outer diameters of the upper side column 222 and the lower side column 23. The top end of the upper side column assembly 22 is provided with a hinge seat 21 for hinged connection with the moving umbrella disc support rod 142. The hinge seat 21 is simultaneously fixed to the top ends of the outer cover tube 221, the upper side column 222, and the guide tube 223. The upper end of the guide tube 223 is embedded inside the upper side column 222, and the lower end is embedded... Inside the lower pillar 23, guide strips 2221 are provided inside the upper pillar 222 and the lower pillar 23. A guide groove 2231 that mates with the guide strip 2221 is provided outside the guide tube 223. Preferably, to increase the smoothness of relative sliding, three sets of pulleys 224 are provided on the guide tube 223. One set is vertically located on the side wall of the lower end of the guide tube 223 and is rolletably connected to the side wall of the lower pillar 23. The other two sets are respectively located in the guide groove 2231 and are rolletably connected to the guide strip 2221. (Refer to...) Figure 3 The lower column 23 is provided with a sliding groove 231, and the sliding seat 24 is slidably disposed in the sliding groove 231. The upper end and the lower end of the sliding groove 231 are respectively provided with an upper limit member 232 and a lower limit member 233, which are used to control the stroke range of the sliding seat 24.

[0020] like Figure 4As shown, the traction assembly 25 includes an opening and closing winding device 251 located on the lower side post 23, paracord 252, a first pulley 253, a second pulley 254, and a paracord fixing member 255 located on the hinge seat 21, and a third pulley 256 located on the sliding seat 24. The first pulley 253 is correspondingly arranged in relation to the inner cavity of the upper side post 222. The second pulley 254, the paracord fixing member 255, and the third pulley 256 are arranged corresponding to the gap between the upper side post 222 and the outer cover tube 221. The opening and closing winding device 251 has a structure including a paracord self-locking member 2514, also known as a self-locking winder, which is a common structure in outdoor umbrellas. It includes a winding shaft for winding the paracord 252, a self-locking mechanism for locking the paracord 252, and a crank 257 for rotating the winding shaft. The handle of the crank 257 extends out of the lower side post 23 for easy cranking. Specifically, as shown... Figure 5 As shown, the opening and closing winding device 251 includes a set of opposing guard plates 2511 and a paracord self-locking member 2514 located at the lower end of the guard plates 2511. The guard plates 2511 are centrally located relative to the inner cavity of the lower post 23, and the lower end of the guard plates 2511 is fixed to the lower post 23. Preferably, the paracord self-locking member 2514 is connected to the guard plates 2511 via a pair of bearings 2513. Above the paracord self-locking member 2514, a paracord guide assembly 2512 is also provided. The paracord guide assembly 2512 includes a guide wheel bracket 25121 and a guide wheel group 25122 disposed thereon. The guide wheel bracket 25121 is fixed to the guard plate 2511, and the guide wheel group 25122 consists of a pair of parallel guide wheels with their outer edges touching. During assembly, as follows... Figure 4 As shown, one end of the paracord 252 is wound around the paracord self-locking member 2514 of the opening and closing winding device 251, and the other end passes through the gap between the guide wheels and extends upward through the inner cavity of the lower side post 23, the guide tube 223 and the upper side post 222. It then passes around the first pulley 253 and the second pulley 254 in sequence and enters the gap between the outer cover tube 221 and the upper side post 222. After passing down the third pulley 256, it is fixed to the paracord fixing member 255 provided on the hinge seat 21.

[0021] like Figure 3 and Figure 4 As shown, the lower end of the elastic element 26 is fixedly connected to the upper end of the guard plate 2511 of the opening and closing winding device 251, and the upper end of the elastic element 26 is fixedly connected to the bottom of the upper side column assembly 22, i.e., the bottom of the guide tube 223. The elastic element 26 can be a longitudinally compressible and restorable compression spring or a gas spring, etc., and in this embodiment, a gas spring is preferred.

[0022] When the umbrella needs to be opened, the parachute cord self-locking component 2514 winds the parachute cord 252, pulling the sliding seat 24 upward. The main support rod 141 and the moving umbrella disc support rod 142 of the opening and closing hinge assembly 14 open relative to each other, causing the fixed umbrella disc 12 and the moving umbrella disc 13 to approach each other. The umbrella frame assembly 1 unfolds. When the sliding seat 24 reaches the top, the parachute cord 252 continues to wind. The parachute cord 252 applies force to the hinge seat 21, compressing the elastic element 26 downward. The upper column assembly 22 slides downward until the outer cover tube 221 touches the sliding seat 24, and then the parachute cord self-locking component 2514 locks the parachute cord 252. When the umbrella needs to be closed, the self-locking component 2514 releases the umbrella rope 252. The elastic element 26, under the action of elastic force, pushes the guide tube upward, causing the upper side column assembly 22 to rise. When the elastic element 26 returns to its initial state, the moving umbrella disc 13 and the fixed umbrella disc 12 move away from each other due to the weight of the umbrella frame assembly 1. The opening and closing hinge assembly 14 closes, and the sliding seat 24 moves down until the umbrella frame assembly 1 is fully closed. Throughout the entire use process, the opening and closing of the umbrella can be completed simply by controlling the tightening or releasing of the umbrella rope 252 with the crank 257. There is no need to simultaneously control the opening and closing of the opening and closing hinge assembly and the winding of the umbrella rope 252, making the operation extremely convenient. Moreover, the height of the side column can be adjusted simultaneously during the opening and closing process, which can effectively prevent the ends of the umbrella ribs of large umbrellas from hitting other objects, resulting in less operational interference and smoother operation.

[0023] Furthermore, to allow the umbrella surface to be adjusted for shading based on the usage environment and sun direction, the lower post 23 is connected to the umbrella base assembly 3 via a rotating assembly 4. The rotating assembly 4 includes a rotating base 41 and a locking assembly 42, such as... Figure 6As shown, the rotating base 41 includes a rotating central shaft 411, a support tube 412, an upper bearing seat 413, ball bearings 414, a lower bearing seat 415, and a lower support base 416. The lower end of the rotating central shaft 411 is fixed to the lower bearing seat 415, and the upper end is connected to the lower side post 23 through a locking assembly 42. The support tube 412 is sleeved on the outside of the rotating central shaft 411 and fixedly installed with the lower side post 23. The lower end of the support tube 412 is fixed to the lower support base 416. 6. The upper bearing seat 413 and the lower bearing seat 415 are rotatably connected by ball bearings 414, and the lower bearing seat 415 is fixed to the umbrella seat assembly 3. Preferably, the top of the rotating central shaft 411 is also rotatably provided with an upper support seat 417. The upper support seat 417 and the rotating central shaft 411 can be connected by rolling elements to reduce rotational resistance. The upper support seat 417 is fixed in cooperation with the lower side column 23 and cooperates with the support tube 412 to increase the rotational stability of the lower side column 23 relative to the rotating central shaft 411. The locking assembly 42 is provided between the lower side column 23 and the rotating central shaft 411 to realize the mutual locking and unlocking of the lower side column 23 and the rotating central shaft 411. The locking assembly can be a locking method such as a pin engagement. Preferably, the locking assembly 42 in this embodiment includes an anti-rotation groove 421 provided around the upper end of the rotating central shaft 411 (see reference). Figure 6 The rotary switch 422 is located on the lower column 23, such as... Figure 7 As shown, the rotary switch 422 includes a switch base 4221, a locking pin 4222 that cooperates with the anti-rotation slot 421, and an operating handle 4223. The locking pin 4222 is fixed to the upper end of the operating handle 4223. The operating handle 4223 is rotatably connected to the switch base 4221. The switch base 4221 is fixedly connected to the upper support base 417.

[0024] In use, the rotating central shaft 411 is fixed to the umbrella seat assembly 3 via the lower bearing seat 415, serving as the rotation center. Pressing the free end of the operating handle 4223 into the guide groove 2231 of the lower side column 23 causes the locking pin 4222 to disengage from the anti-rotation groove 421. When the lower side column 23 is rotated, the support tube 412 is driven to rotate relative to the rotating central shaft 411 to a preset position. The operating handle 4223 is then released, and the locking pin 4222 is re-engaged into the anti-rotation groove 421, thus re-locking the lower side column 23 with the rotation center and completing the rotation operation.

[0025] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
