Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0041] like Figure 1 —The embodiment shown in 14.

[0042] A boneless umbrella comprises an umbrella handle 1, a tracheal umbrella frame 2 is provided on the top of the umbrella handle 1, an umbrella surface 3 is provided on the outer surface of the tracheal umbrella frame 2, a sliding lifting member 7 that can move up and down is provided on the outer surface of the umbrella handle 1, a pneumatic support assembly 4 is also provided on the umbrella handle 1, and the pneumatic support assembly 4 is located above the sliding lifting member 7, the outlet of the pneumatic support assembly 4 is connected to each inlet of the tracheal umbrella frame 2, and a positioning and fixing assembly 8 for fixing the pneumatic support assembly 4 to the umbrella handle 1 is provided inside the umbrella handle 1.

[0043] The tracheal umbrella stand 2 is made of plastic material.

[0044] Reference Figures 1 to 3 As shown, first, the gas in the pneumatic support assembly 4 is transported to the tracheal umbrella frame 2 by moving the sliding lifter 7 upward. After receiving the gas from the pneumatic support assembly 4, the tracheal umbrella frame 2 expands, thereby driving the umbrella surface 3 to form the shape of an umbrella. Compared with the frame of an existing umbrella, the tracheal umbrella frame 2 can undergo a larger deformation without breaking, thereby increasing the service life of the umbrella.

[0045] The pneumatic support assembly 4 includes an airbag 41 on the outer surface of the umbrella handle 1, and a first sleeve 42 is also provided on the top of the outer surface of the umbrella handle 1. The airbag 41 is located between the sliding lifting member 7 and the first sleeve 42. The conical surface of the top of the first sleeve 42 is provided with at least one connecting groove 44. The outer surface of the first sleeve 42 is provided with a second sleeve 43. The first sleeve 42 and the second sleeve 43 form an air path for air circulation. The outlet of the airbag 41 is connected to the air path. The end of the second sleeve 43 is provided with an external pipe 45, and the external pipe 45 is connected to each air inlet of the tracheal umbrella frame 2.

[0046] Reference Figure 4 As shown, after the sliding lifter 7 rises, it drives the airbag 41 to move upward in the direction guided by the first sleeve 42. During the rising process of the sliding lifter 7, the airbag 41 contracts, so that the gas in the sliding lifter 7 is transported to the tracheal umbrella stand 2 through the air channel and the external pipe 45, thereby expanding the tracheal umbrella stand 2 to form an umbrella shape.

[0047] The outer surface of the top of the umbrella handle 1 is also sleeved with a lifting tube 46, and the inner wall of the lifting tube 46 is also provided with a baffle 48. The baffle 48 is located between the top of the first sleeve 42 and the inner top wall of the external tube 45. The inner diameter of the baffle 48 is larger than the outer diameter of the umbrella handle 1. A first spring 47 is provided inside the lifting tube 46, and the first spring 47 is located between the baffle 48 and the inner top wall of the external tube 45.

[0048] Reference Figure 4 and Figure 5As shown, when the sliding lifting member 7 moves upward and drives the airbag 41 to contract, it slightly drives the first sleeve 42 to move upward. The outer diameter of the top of the first sleeve 42 is the same as the outer diameter of the lifting tube 46. Therefore, when the first sleeve 42 moves upward, it also drives the lifting tube 46 to move upward, thereby causing the first spring 47 to contract, and the outer wall of the lifting tube 46 gradually closes the connecting hole between the air outlet of the external pipe 45 and the air passage. When the airbag 41 is fully contracted, the outer wall of the lifting tube 46 completely closes the connecting hole connecting the air outlet of the external pipe 45 and the air passage, thereby preventing the gas in the tracheal umbrella stand 2 from overflowing reversely; correspondingly, when the sliding lifting member 7 moves downward, the elastic force of the first spring 47 causes the lifting tube 46 and the first sleeve 42 to move downward, gradually releasing the blockage of the connecting hole connecting the air outlet of the external pipe 45 and the air passage, allowing the gas in the tracheal umbrella stand 2 to return to the airbag 41 through the air passage, making it convenient to organize and store the umbrella.

[0049] A closing member 6 is further provided at the top of the umbrella handle 1, and the closing member 6 includes a connecting member 61 arranged in the inner wall of the top of the umbrella handle 1, and a closed cavity 62 and a vent 63 are provided inside the connecting member 61. The closed cavity 62 and the vent 63 are connected and distributed at a ninety-degree angle. The vent 63 passes through the connecting member 61, and a plug 64 is provided on the upper surface of the connecting member 61 to close the closed cavity 62. The connecting member 61 also includes a communicating hole 65 provided on the outer surface of the top of the umbrella handle 1, and the closed cavity 62 is communicated with the air path through the vent 63 and the communicating hole 65.

[0050] Reference Figure 4 、 Figure 11 and Figure 12 As shown, at the beginning of use, the plug 64 is pulled out from the closed cavity 62, and the air path formed by the first sleeve 42 and the second sleeve 43 is connected through the channel formed by the closed cavity 62, the vent hole 63 and the connecting hole 65. When the airbag 41 is in the contracted state, the tracheal umbrella frame 2 is filled with gas, and the closed cavity 62 is blocked by the plug 64. When the airbag 41 is expanded, the gas in the tracheal umbrella frame 2 is drawn into the airbag 41 through the air path, so that the umbrella can be organized and stored.

[0051] The positioning and fixing assembly 8 includes two second fixing holes 83 opened on the inner wall of the umbrella handle 1 and a first fixing hole 81 opened on the inner wall of the sliding lifting member 7. A steel ball 82 adapted to the first fixing hole 81 is provided in each of the second fixing holes 83, and an elastic sheet 84 is provided between the two steel balls 82.

[0052] Reference Figure 13As shown, when the sliding lifter 7 moves upward, when the first fixing hole 81 on the inner wall of the sliding lifter 7 moves to the position of the steel ball 82, the elastic sheet 84 causes the steel ball 82 to penetrate into the first fixing hole 81 under the action of elastic force, thereby clamping the sliding lifter 7 and limiting and fixing the sliding lifter 7; when it is necessary to move the sliding lifter 7 again, it is only necessary to use greater force to separate the first fixing hole 81 and the steel ball 82 to release the limited fixing state.

[0053] The umbrella handle 1 includes a telescopic rod 11 and a connecting rod 12 . The telescopic rod 11 is sleeved inside the connecting rod 12 . A lifting control assembly 5 for extending and retracting the umbrella handle 1 is provided at the bottom of the telescopic rod 11 .

[0054] The lifting control assembly 5 includes a fixing sleeve 52, a mounting groove 53 is transversely opened in the fixing sleeve 52, a guide column 56 is provided on the inner wall of the mounting groove 53, a control ring 54 is provided inside the mounting groove 53, the end of the telescopic rod 11 passes through the inner hole of the control ring 54 and is connected to the fixing sleeve 52, a block 55 is provided on the inner wall of the control ring 54, a slot 57 adapted to the block 55 is opened at the bottom of the outer surface of the connecting rod 12, a return spring is provided between the guide column 56 and the control ring 54, a second spring 58 is provided in the telescopic rod 11, one end of the second spring 58 is connected to the bottom of the telescopic rod 11, and the other end of the second spring 58 is connected to the connecting rod 12.

[0055] Reference Figure 7 and Figure 8 As shown, when the umbrella handle 1 is to be extended, it is only necessary to press the control ring 54 to extend the umbrella handle 1. Specifically, the control ring 54 is first pressed to contract the return spring provided between the control ring 54 and the guide column 56. At this time, the clamping block 55 is disengaged from the clamping slot 57, and the telescopic rod 11 and the connecting rod 12 are separated under the elastic force of the second spring 58, so that the umbrella handle 1 is extended, making it more convenient for people to use when opening the umbrella; when it needs to be retracted, it is necessary to press the connecting rod 12 to move it toward the telescopic rod 11 so that the clamping slot 57 is engaged with the clamping block 55, thereby retracting the umbrella handle 1.

[0056] A handle 51 is provided on the outer surface of the fixing sleeve 52, and the handle 51 includes a handle body 511. The inner bottom wall of the handle body 511 is provided with a fixing ring 512 adapted to the telescopic rod 11. The fixing ring 512 is fixedly connected to the telescopic rod 11 by screws, and a button 514 adapted to the pressing position of the control ring 54 is provided on the outer surface of the handle body 511.

[0057] The inner wall of the fixing ring 512 is provided with symmetrical guide grooves 513 , and the outer surface of the bottom of the fixing sleeve 52 is provided with guide blocks 515 adapted to the guide grooves 513 . The guide grooves 513 and the guide blocks 515 are snap-fitted.

[0058] Reference Figure 9 As shown, when the fixing sleeve 52 needs to be connected and installed with the handle body 511, the guide block 515 is first engaged with the guide groove 513, and then the handle body 511 and the fixing sleeve 52 are fixed by screws through the holes at the bottom; in this embodiment, the fixing sleeve 52 and the handle body 511 are prevented from rotating by engaging the guide groove 513 with the guide block 515, and the umbrella handle 1 is extended by pressing the control ring 54 through the button 514 located on the outer surface of the handle body 511.

[0059] The sliding lifting member 7 includes a moving tube 71 slidably arranged on the outer surface of the umbrella handle 1, the outer surface of the moving tube 71 is sleeved with a support plate 72, a connecting ring 73 is provided between the moving tube 71 and the support plate 72, an opening and closing control mechanism 9 for controlling the airbag 41 to be connected to or closed with the outside is provided between the sliding lifting member 7 and the airbag 41, the opening and closing control mechanism 9 includes a plurality of through holes 91 opened on the connecting ring 73, a lifting ring 92 is further provided on the upper surface of the connecting ring 73, and the lifting ring 92 is sleeved on the outer surface of the moving tube 71, a sealing ring 97 is provided on the upper surface of the lifting ring 92, a lifting column 93 adapted to the through hole 91 is provided on the bottom surface of the lifting ring 92, a retaining ring 94 is fixedly provided on the outer surface of the moving tube 71 and is also sleeved with a transmission ring 95, a transmission spring 96 is provided between the retaining ring 94 and the transmission ring 95, and a lifting column 98 adapted to the lifting column 93 is provided on the top surface of the fixed sleeve 52.

[0060] In this embodiment, referring to Figure 19 As shown, an annular groove is provided at the bottom of the outer surface of the movable tube 71, and a spring piece is correspondingly provided on the top side wall of the fixed sleeve 52. The spring piece is adapted to the annular groove, that is, when the movable tube 71 moves to the fixed sleeve 52, the fixed sleeve 52 is fixed to the movable tube 71 by clamping the spring piece and the annular groove.

[0061] Reference Figures 15 to 19As shown, the specific air bag 41 is connected to the outside through the bottom of the umbrella handle 1. More specifically, the air bag 41 is connected to the outside through a through hole 91 opened on the connecting ring 73. The connection or closure of the air bag 41 with the outside is controlled by controlling the opening and closing of the through hole 91. When the tracheal umbrella frame 2 and the umbrella surface 3 need to be stored, the sliding lifting member 7 is driven to move in the direction of the lifting control assembly 5. At this time, as the telescopic rod 11 and the connecting rod 12 in the umbrella handle 1 are shortened and the card slot 57 is engaged with the card block 55, the gas in the tracheal umbrella frame 2 will first be drawn into the air bag 41 during this process. As the sliding lifting member 7 moves downward and moves to the bottom, the lifting column 98 is located directly below the lifting column 93. At this time, the lifting column 98 will support the lifting column 93 to prevent it from moving further downward. The transmission of the column 93, the lifting ring 92 and the transmission ring 95 causes the transmission spring 96 to contract, and the through hole 91 is no longer closed by the sealing ring 97. At this time, the gas in the airbag 41 will escape to the outside through the through hole 91, and the gas in the airbag 41 will be discharged; when the tracheal umbrella frame 2 and the umbrella cover 3 need to be opened, the sliding lifting member 7 moves upward. At this time, since the transmission ring 95 and the sealing ring 97 are no longer blocked by the jacking column 98, the transmission ring 95 and the sealing ring 97 are moved toward the lifting control component 5 under the elastic force of the transmission spring 96 to close the through hole 91. At this time, the airbag 41 is already full of gas, and then as the sliding lifting member 7 moves upward, the airbag 41 is compressed, so that the gas in the airbag 41 is transported to the tracheal umbrella frame 2, so that the tracheal umbrella frame 2 opens to form an umbrella shape, completing the opening of the umbrella.

[0062] The working process of the present invention is as follows: first, the airbag 41 is contracted by moving the sliding lifting member 7 upward, so that the gas in the airbag 41 is transported to the tracheal umbrella frame 2 through the air path formed by the first sleeve 42 and the second sleeve 43. After receiving the gas from the airbag 41, the tracheal umbrella frame 2 expands to form an umbrella shape, thereby forming an umbrella. At this time, the sliding lifting member 7 is fixed by the positioning and fixing component 8, and then the button 514 is pressed to drive the control ring 54 to separate the clamping block 55 from the clamping groove 57, thereby extending the umbrella handle 1 for convenient use; when it is necessary to receive First, the sliding lifter 7 moves downward. When the sliding lifter 7 moves downward, the gas in the tracheal umbrella frame 2 is drawn into the airbag 41. Then, as the sliding lifter 7 moves downward, the lifting column 98 lifts the lifting column 93 upward, and the sealing ring 97 and the transmission ring 95 move upward to shrink the transmission spring 96. At this time, the sealing ring 97 no longer seals the through hole 91. At this time, the gas in the airbag 41 is discharged to the outside through the through hole 91. When the sliding lifter 7 moves to the bottom and the umbrella handle 1 is retracted to the bottom, the clamping groove 57 and the clamping block 55 are clamped and fixed.

[0063] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
