Description

Technical Field

[0001] This invention relates to the field of hand-push umbrella technology, and in particular to a hand-push umbrella. Background Technology

[0002] Hand-operated umbrellas are widely used in applications such as rain umbrellas, parasols, and patio umbrellas. Especially in patio umbrellas, because of their large canopy and the significant force required to open them, the elastic pressure generated by automatic mechanisms like springs is substantial, hence the common use of hand-operated umbrellas. Hand-operated umbrellas typically consist of a shaft, with a connecting rod assembly rotating at the other end. This connecting rod assembly controls the opening and closing of the canopy. One end of the connecting rod assembly connects to a sliding sleeve that slides along the shaft. Once the sleeve slides into position on the shaft, it locks in place, thus opening the canopy.

[0003] For example, the Chinese patent application with patent number CN2021208512376, published on November 5, 2021, entitled "A Novel Structure of a Hand-Pushed Sunshade Umbrella", includes an umbrella frame assembly, a pole assembly in the middle of the umbrella frame assembly, an upper umbrella plate assembly between the pole assembly and the umbrella frame assembly, a slidable armrest shell assembly installed at the upper end of the pole assembly, the armrest shell assembly for opening or closing the umbrella frame assembly, a spring pin that can move laterally installed inside the armrest shell assembly, a number of positioning holes for the spring pin to pass through on the pole assembly, and a button for controlling the movement of the spring pin on the armrest shell assembly.

[0004] Existing sliding sleeves, i.e. armrest shell assemblies, typically use elastic locking mechanisms to lock the umbrella fabric in place. However, the limiting structure using elastic plates generally suffers from the problem that the locking mechanism relies on elastic locking, requiring overcoming the locking force during unlocking, making unlocking difficult. Furthermore, the locking part is prone to damage due to the elastic force of the elastic plate. On the other hand, the button and spring-loaded pin structure, as described above, suffers from the problem that the limiting surface of the spring-loaded pin is small, and the locking part is also prone to damage, affecting the user experience and lifespan of the hand-pushed umbrella. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a push umbrella that has stable locking, convenient unlocking, and high reliability of the locking part, thereby extending the service life of the push umbrella and improving the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hand-push umbrella includes a main pole and a sliding sleeve. The main pole has a circumferential array of several first connecting rods rotatably connected to it. The outer sides of the first connecting rods are all connected to the umbrella fabric. The sliding sleeve has second connecting rods rotatably connected to each of the first connecting rods. One end of each second connecting rod is rotatably connected to a first connecting rod. The sliding sleeve slides along the main pole and, through the second connecting rods, drives the first connecting rods to open and close the umbrella fabric. The main pole has a locking element extending outwards. The sliding sleeve includes a sliding part connected to the second connecting rods and a rotating part rotatably connected to the sliding part. The rotating part has a limiting groove that engages with the locking element. The upper end of the rotating part has an unlocking opening communicating with the limiting groove. On one side of the unlocking opening, the rotating part has a blocking part located above the limiting groove. The locking element moves in and out of the limiting groove through the unlocking opening to lock and unlock the sliding sleeve on the main pole. The sliding part has an opening groove for the locking element to pass through, and on both sides of the opening groove, the sliding part has pressure parts that can support the upper end of the blocking part.

[0008] In one type of hand-push umbrella, the middle position of the opening slot and the locking member are located on the same radial plane of the main shaft, and the length of the blocking part is greater than the width of the opening slot.

[0009] In the aforementioned type of hand-push umbrella, the limiting groove is provided with an opening on the inner circumference of the rotating part and a closed arrangement on the outer circumference of the rotating part.

[0010] In one of the aforementioned hand-push umbrellas, the locking component is equipped with an elastic reset component, and the locking component is outwardly supported by the elastic force of the elastic reset component.

[0011] In one of the aforementioned hand-push umbrellas, the main pole has a mounting hole along its axis, and a connecting frame is provided in the mounting hole. The connecting frame is detachably connected to the main pole, and the lower end of the locking member is rotatably connected to the connecting frame.

[0012] In one of the aforementioned hand-push umbrellas, a locking ring is provided on the outside of the main pole and connected to the connecting frame. The locking ring limits the upward travel of the sliding sleeve on the outside of the main pole.

[0013] In the aforementioned type of hand-push umbrella, the lower end of the locking component is rotatably connected to the main pole, the upper end of the locking component is provided with an outwardly protruding positioning block, the main pole is provided with a through groove for the positioning block to extend out, the lower end of the positioning block is smoothly connected to the outer periphery of the main pole, and the upper end of the positioning block protrudes to the outside of the main pole.

[0014] In the aforementioned type of hand-push umbrella, the sliding part includes an upper shell and a lower shell that are joined together. The upper end of the rotating part is provided with a rotating boss, and the lower end of the rotating part extends to the lower shell to form a grip section. When the upper shell and the lower shell are fixed, the rotating boss is rotatably limited between the upper shell and the lower shell.

[0015] In one of the aforementioned hand-push umbrellas, an opening groove and a pressure section are provided on the upper shell, and a transition fillet is provided between the opening groove and the pressure section.

[0016] In one of the aforementioned hand-push umbrellas, the inner circumference of the rotating part is cylindrical, and the outer circumference of the main shaft is provided with several vertical lines parallel to its axis.

[0017] The beneficial effects of this invention are:

[0018] The hand-push umbrella disclosed in this invention includes a main pole and a sliding sleeve. The sliding sleeve slides along the main pole to drive the rotation of the first and second connecting rods. The sliding sleeve cooperates with a locking member to lock the sliding sleeve in place, i.e., when the umbrella fabric is opened. The sliding sleeve in this application includes two parts: a sliding part and a rotating part. The sliding part slides relative to the axis of the main pole and drives the second connecting rod. The rotating part is rotatably arranged relative to the sliding part. The rotation of the rotating part causes the blocking part or unlocking opening to be opposite to the locking member. When the unlocking opening corresponds to the locking member, the locking member can enter the limiting groove from the outside or move from the limiting groove to the outside. When the locking member enters the limiting groove and... When used in conjunction with the blocking part, the unlocking opening is aligned with the locking member by rotating the rotating part, thus unlocking the sliding sleeve and allowing the umbrella fabric to be gathered. The unlocking of this application relies on the rotation of the rotating part to avoid obstruction, eliminating the need to overcome the locking force from the locking member, thereby extending the service life of the blocking part. Unlocking is completed by rotating the rotating part, making operation convenient. The locking member can smoothly enter and exit the sliding part from the opening slot, facilitating the engagement between the locking member and the limiting slot in the rotating part. The upper end of the blocking part is supported by the pressure part, which significantly improves the pressure-bearing capacity of the blocking part and ensures the locking effect when the blocking part and the blocking member work together to open the umbrella by hand.

[0019] Preferably, the center of the opening groove and the locking member are located on the same radial plane as the main rod, and the length of the blocking part is greater than the width of the opening groove. The sliding part only slides axially relative to the main rod and does not rotate circumferentially. Since the center of the opening groove and the locking member are located on the same radial plane as the main rod, and the length of the blocking part is greater than the width of the opening groove, the pressure part can remain pressed against the upper end of the blocking part when the locking member rotates out of the limiting groove, ensuring the pressing and protective function of the pressure part against the blocking part when the locking member is unlocked.

[0020] Preferably, the limiting groove is provided with an opening on the inner circumference of the rotating part and a closed arrangement on the outer circumference of the rotating part. The closed outer circumference of the limiting groove serves to strengthen the structure, improve the reliability of the blocking part, and extend the service life of the blocking part.

[0021] Preferably, the locking member is equipped with an elastic reset member, which extends outward under the elastic force of the reset member. This elastic outward extension allows the locking member to enter the limiting groove for locking when needed, either from the unlocking opening or by sliding between the blocking positions through the elastic deformation of the reset member, thus facilitating the locking block's limiting function.

[0022] Preferably, the main rod has a mounting hole along its axis, and a connecting bracket is installed in the mounting hole. The connecting bracket is detachably connected to the main rod, and the lower end of the locking component is rotatably connected to the connecting bracket. Installing the locking component via the connecting bracket facilitates its integration within the main rod.

[0023] Preferably, the main pole is equipped with a locking ring that connects to the connecting frame. The locking ring limits the upward travel of the sliding sleeve on the outside of the main pole. The locking ring serves both to cooperate with the connecting frame, improving the strength of the connection between the inner pole and the connecting pole, and to limit the upward travel of the sliding sleeve, thereby improving the structural reliability of the umbrella after it is opened.

[0024] Preferably, the lower end of the locking component is rotatably connected to the main rod, and the upper end of the locking component is provided with an outwardly protruding positioning block. The main rod is provided with a through groove for the positioning block to extend out. The lower end of the positioning block is smoothly connected to the outer periphery of the main rod, and the upper end of the positioning block protrudes to the outside of the main rod. The lower end of the positioning block is connected to the main rod, which facilitates its entry into the limiting groove from the blocking part through the elastic deformation of the elastic reset component. The upper end of the positioning block protrudes to the outside of the main rod, ensuring that it cooperates with the blocking part to achieve a locking effect.

[0025] Preferably, the sliding part includes an upper shell and a lower shell joined together. The upper end of the rotating part is provided with a rotating boss, and the lower end of the rotating part extends to the bottom of the lower shell to form a gripping section. When the upper shell and the lower shell are fixed, the rotating boss is rotatably limited between the upper shell and the lower shell. The rotating boss is limited when the upper shell and the lower shell are fixed, realizing the rotational connection between the rotating part and the sliding part. The setting of the rotating boss also strengthens the thickness of the limiting groove, improves the structural strength of the blocking part, and has a longer locking life.

[0026] Preferably, the opening groove and the pressure section are located on the upper housing, and a transition fillet is provided between the opening groove and the pressure section. This avoids stress concentration and improves structural strength.

[0027] Preferably, the inner circumference of the rotating part is cylindrical, and the outer circumference of the main rod has several vertical grooves parallel to its axis. The vertical grooves serve as a sliding guide, and at the same time, the vertical grooves reduce the contact area between the rotating part and the main rod, thereby reducing the rotational friction between the rotating part and the main rod.

Detailed Implementation

[0037] This invention proposes a hand-push umbrella, comprising a main pole and a sliding sleeve. The main pole has a circumferential array of several first connecting rods rotatably connected to it. The outer sides of the first connecting rods are all connected to the umbrella fabric. The sliding sleeve has second connecting rods rotatably connected to each of the first connecting rods, with one end of each second connecting rod rotatably connected to a first connecting rod. The sliding sleeve slides along the main pole and, through the second connecting rods, drives the first connecting rods to open and close the umbrella fabric. The main pole has a locking component extending outwards. The sliding sleeve includes a sliding part connected to the second connecting rods and a rotating part rotatably connected to the sliding part. The rotating part has a limiting groove that engages with the locking component. The upper end of the rotating part has an unlocking opening communicating with the limiting groove. On one side of the unlocking opening, the rotating part has a blocking part located above the limiting groove. The locking component moves in and out of the limiting groove through the unlocking opening to lock and unlock the sliding sleeve on the main pole. The sliding part has an opening groove for the locking component to pass through, and on both sides of the opening groove, the sliding part has pressure parts that abut against the upper end of the blocking part.

[0038] In this invention, the size of the unlocking opening is not less than the lateral dimension of the locking member. In application, the locking member cooperates with the blocking part to complete the limit of opening the umbrella cloth to the correct position. When it is necessary to close the umbrella, the rotating part is rotated around the axis of the main pole so that the locking member is opposite to the unlocking opening, thereby completing the unlocking. The operation is convenient.

[0039] In this invention, the upper end of the limiting groove is provided with an unlocking opening and a blocking part. The blocking part locks the locking member within the limiting groove. When the locking member rotates to the end of the blocking part facing the unlocking opening, the blocking part still locks the locking member. Since the pressure of the locking member on the blocking part is located at the end of the blocking part, it will generate a large rotational torque on the end of the blocking part away from the unlocking opening. There is a gap between the pressure part and the blocking part. When the blocking part is deformed by the pressure of the locking member, the pressure part presses against the blocking part, avoiding the problem that the blocking part is easily damaged under the action of rotational torque, thus extending the service life of the hand umbrella.

[0040] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] One embodiment of the hand-pushed umbrella disclosed in this invention is as follows: Figures 1 to 7As shown, the system includes a main rod 1 and a sliding sleeve 2. Several first connecting rods 3, arranged in a circular array around the axis of the main rod 1, are rotatably connected to the main rod 1. The outer sides of the first connecting rods 3 are all connected to the umbrella fabric. Several second connecting rods 4, corresponding one-to-one with the first connecting rods 3, are rotatably connected to the sliding sleeve 2. In this embodiment, there are eight first connecting rods 3 and eight second connecting rods 4. One end of each second connecting rod 4 is rotatably connected to a first connecting rod 3. The first connecting rod 3 has a connecting sleeve 5, which locks in place after sliding on the first connecting rod 3. One end of the second connecting rod 4 is hinged to the connecting sleeve 5. The umbrella fabric is connected to the eight first connecting rods 3. The sliding sleeve 2 slides along the main rod 1 and drives the first connecting rod 3 to rotate through the second connecting rod 4 to realize the opening and closing of the umbrella fabric. The main rod 1 is provided with a locking member that extends to the outside of the main rod 1. The sliding sleeve 2 includes a sliding part 26 connected to the second connecting rod 4 and a rotating part 21 rotatably connected to the sliding part 26. The sliding part 26 includes an upper shell 27 and a lower shell 28 that are locked together by upper and lower bolts. The rotating part 21 is a rotating body. The upper end of the rotating part 21 is provided with an outwardly protruding rotating boss 25. The inner circumference of the rotating part 21 is a cylindrical surface that contacts the outer circumference of the main rod 1. The outer ends of the outer circumference of the main rod 1 are arranged in a circular pattern. In this embodiment, the outer circumference of the main rod 1 is arranged with several vertical lines parallel to the axis of the main rod 1, so that the cross-sectional shape of the main rod 1 is a circular wavy line, which reduces the rotational friction between the rotating part 21 and the main rod 1. The lower housing 28 contains a bearing-fitting rotating part 21 and a rotating boss 25. When the upper housing and the lower housing are fixed, the rotating boss is rotatably limited between the upper housing and the lower housing. After the upper housing 27 and the lower housing 28 are connected, the rotation of the rotating part 21 is limited. One end of the second connecting rod 4 is rotatably connected to the sliding part 26. The rotating part 21 contacts the outer periphery of the main rod 1, and the sliding part 26 is connected to the rotating part 21, rotatably disposed outside the rotating part 21. The rotating part 21 is provided with a limiting groove 22 that fits the locking element. The limiting groove 22 has an unlocking opening 23 at the upper end of the rotating part 21. The rotating part 21 has a blocking part 24 located above the limiting groove 22 on one side of the unlocking opening 23. Figure 5As shown, the limiting groove 22 is symmetrically shaped like an "L". The unlocking opening 23 is the vertical section of the limiting groove 22, and the blocking part 24 is the inner wall surface of the rotating part 21 on one side of the vertical section. The locking member moves in and out of the limiting groove 22 through the unlocking opening 23 to lock and unlock the sliding sleeve 2 on the main rod 1. The sliding part 26 is more precisely an opening groove 271 on the inner circumference of the upper housing 27 and the main rod with clearance fit, which allows the locking member to pass through. The sliding part 26 has pressure parts 272 on both sides of the opening groove 271 that can support the upper end of the blocking part 24. When the locking member is located below the end of the blocking part 24 away from the unlocking opening 23, the deformation of the blocking part 24 is small, and the upper end of the blocking part 24 is flush with the upper end of the rotating part 21. There is a movable gap between the upper end of the rotating part 21 and the upper housing 27 to complete the rotation of the rotating part 21 relative to the sliding part 26. When the locking member is located below the end of the blocking part 24 facing the unlocking opening 23, the outer end of the blocking part 24 deforms upward, and the upper side of the outer end of the blocking part 24 abuts against the pressure part 272, thereby improving the deformation resistance of the blocking part 24. The opening groove 271 and the pressure part 272 are provided in the upper housing 27, and a transition fillet is provided between the opening groove 271 and the pressure part 272.

[0043] The locking component can be either elastic or rigid. If the locking component is rigid, when the sliding sleeve 2 slides into place, the umbrella fabric is fully opened on the first connecting rod 3. The locking component needs to enter the limiting groove 22 through the unlocking opening 23. After entering the limiting groove 22, the locking component rotates, causing it to engage with the blocking part 24 to limit the sliding sleeve 2. If the locking component is elastic, its deformation can be used to lock it into the limiting groove 22. In this embodiment, the locking component includes two locking blocks 6 symmetrically arranged around the axis of the main rod 1, and each locking block 6 is equipped with an elastic reset component. The lower end of the locking block 6 is rotatably connected to the main rod 1 via a pin. The elastic reset component is a torsion spring sleeved on the rotating pin of the locking block 6, with both ends of the torsion spring abutting against the locking block 6 and the connecting frame 7, respectively. The locking blocks 6 can also be configured as a single block, three blocks, or four blocks, etc., depending on the needs and the lateral dimensions of the main rod 1.

[0044] The upper end of the locking block 6 is provided with an outwardly protruding positioning block 61, and the main rod 1 is provided with a through groove 11 for the positioning block 61 to extend out. When the locking block 6 is fitted into the limiting groove 22, the lower end of the positioning block 61 is smoothly connected to the outer periphery of the main rod 1, and the upper end of the positioning block 61 protrudes to the outside of the main rod 1. A transition plane is provided between the lower end and the upper end of the positioning block 61.

[0045] The main rod 1 has a mounting hole along its axis, and a connecting frame 7 is provided in the mounting hole. The connecting frame 7 includes a connecting ring 71, and two connecting plates 72 parallel to its axis and located on both sides of the axis are provided in the connecting ring 71. A gap is formed between the connecting plates 72 to accommodate the locking block 6. The connecting frame 7 is detachably connected to the main rod 1, and the lower end of the locking element is rotatably connected to the connecting frame 7. Figure 7 At this point, the locking block 6 is compressed within the connecting frame 7, overcoming the elastic force of the elastic reset member. A locking ring 8 connected to the connecting frame 7 is provided on the outside of the main rod 1, limiting the upward travel of the sliding sleeve 2 on the outside of the main rod 1. The locking ring 8, connecting frame 7, and main rod 1 are fixed together by a connecting pin. The lower end of the rotating part 21 extends downwards to the outside of the lower end of the sliding part 26, forming a gripping section 20.

[0046] When in use, the grip section 20 can be operated to make the rotating part 21 rotate around the axis of the main rod 1, thereby adjusting the position of the locking part in the limiting groove 22. This allows for switching between the locking part engaging with the blocking part 24 and engaging with the unlocking opening 23, making unlocking convenient and operation easy.

[0047] To improve the structural reliability of the blocking part and the limiting groove within the rotating part, one embodiment of the hand-push umbrella disclosed in this invention is as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the center of the opening slot 271 and the locking member are located on the same radial plane as the main rod 1, and the length of the blocking part 24 is greater than the width of the opening slot. Here, "length of the blocking part 24" refers to the length of the blocking part in the circumferential direction of the main rod. The limiting slot 22 is provided with an opening on the inner circumference of the rotating part 21 and is closed on the outer circumference of the rotating part 21. Here, "closed" means that the limiting slot 22 is not conductive on the outer circumference of the rotating part 21, forming a continuous wall surface to strengthen the structure of the blocking part 24.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
