Description

Technical Field

[0001] The utility model relates to the technical field of outdoor parasols or umbrellas, in particular to an opening and closing mechanism of a parasol or umbrella. Background Art

[0002] Currently, the sunshade parts of existing parasols or awnings are mostly opened and closed by shaking the umbrella rope, manually pulling the umbrella rope, or directly pushing it with hands. The first two methods are complex in structure and have many related parts, which can easily cause the overall function to fail due to quality or coordination problems of a certain part. The direct pushing method is more laborious when the sunshade part is large. People with less strength or short height have difficulty in operation, and may even be unable to open and close normally. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an opening and closing mechanism of a parasol or an awning with a simple structure, through which the sunshade part of the parasol or the awning can be easily and conveniently unfolded or folded.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A parasol or awning opening and closing mechanism comprises a frame, wherein the frame comprises an upper plate and a lower plate, the upper plate being provided with a plurality of long support bones for supporting a sunshade cloth, the lower plate being provided with a plurality of short support bones, one short support bone being connected to one long support bone, the upper plate being connected to the lower plate via a gas spring, the upper plate and the lower plate being moved away from each other by opening the gas spring, and the frame being opened for sunshade, the upper plate and the lower plate being moved closer to each other by contracting the gas spring.

[0006] A mounting end is respectively provided on the cylinder body of the gas spring and the protruding end of the piston rod of the gas spring. The two mounting ends are arranged opposite to each other along the movable direction of the piston rod of the gas spring. One of the mounting ends is fixedly connected to the upper disk body, and the other mounting end is fixedly connected to the lower disk body.

[0007] The upper and lower plates are connected by a connecting rod, which includes a first and a second coaxially retractable rod. The upper plate is fixedly mounted on the first rod, and the lower plate is fixedly mounted on the second rod. The gas spring is mounted within the connecting rod. The connecting rod serves to firstly improve the overall connection and operational rigidity, and secondly, allows the gas spring to be fully mounted within the connecting rod, protecting the gas spring and increasing its overall service life.

[0008] Each mounting end is provided with a mounting portion, one of which is fixedly connected to the second rod via a first fixing member, and the other mounting portion is fixedly connected to the first rod or the upper plate via a second fixing member, thereby achieving stable mounting of both ends of the gas spring and ensuring its stable function.

[0009] The first fixed connection member includes a first connecting tube that is threaded onto the corresponding mounting portion, with both ends of the first connecting tube extending outwardly from the corresponding mounting portion, and both ends of the first connecting tube being threaded onto the second rod body. First internal threaded connection holes are respectively provided at the two ends of the first connecting tube, and a first connecting bolt that matches the first internal threaded connection hole extends from the outside of the second rod body and is threaded into the corresponding first internal threaded connection hole to achieve a fixed connection between the corresponding mounting portion and the second rod body. The structure is simple, easy to install and disassemble, low in cost, and stable in connection; one mounting end of the gas spring can be stably installed in the second rod body, and the lower disc is fixed to the second rod body, which is equivalent to a fixed connection between the gas spring and the lower disc.

[0010] A fixing ring is mounted on the exterior of the second rod at a position corresponding to the mounting location of the first fixed connector. The first connecting bolt passes through the fixing ring and the corresponding wall surface of the second rod, and is screwed into the corresponding first internally threaded connection hole. The fixing ring is used to increase the rigidity of the connection. When the umbrella or tent body is used as a hanging umbrella, the bottom of the fixing ring is sealed and installed at the bottom of the second rod, thereby sealing the bottom of the second rod.

[0011] The second fixing member includes a second connecting tube that is threaded onto the corresponding mounting portion, with both ends of the second connecting tube extending outward from the corresponding mounting portion. The corresponding mounting portion extends upward from the first rod and extends into the upper plate. The two ends of the second connecting tube are threaded onto the upper plate, and a second internally threaded connection hole is provided at each end of the second connecting tube. A second connecting bolt that matches the second internally threaded connection hole extends from the outside of the upper plate and is threaded into the corresponding second internally threaded connection hole to achieve a fixed connection between the corresponding mounting portion and the upper plate. The structure is simple, easy to install and disassemble, low in cost, and stable in connection. The gas spring can be stably fixed to the upper plate at one mounting end, and the fixed connection between the gas spring mounting end, the upper plate, and the first rod is achieved simultaneously through a structure.

[0012] The gas spring is driven by a pull-wire switch, which is arranged on the outside, so as to facilitate the opening and closing operation of the sunshade part from the outside.

[0013] Compared with the prior art, the advantages of the present invention are: simple structure, easy operation, and the characteristic of gas springs that can store kinetic energy is utilized to convert the potential energy generated when the frame is folded into kinetic energy and store it in the gas spring. When the sunshade part of the umbrella or canopy needs to be opened, the kinetic energy stored in the gas spring is released to easily open the sunshade part. When the sunshade part is folded, through corresponding driving and providing a little assistance to the frame, the gravity and potential energy of the frame, sunshade cloth, etc. jointly apply force to offset the elastic force of the gas spring and store the force in the gas spring for use in opening the sunshade part next time. For a parasol or canopy using this opening and closing mechanism, when folding, the upper disk and the lower disk are close to each other, and when opening, the upper disk and the lower disk are far apart, forming an umbrella or canopy that is completely different from the traditional structure.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] As shown in the figure, an opening and closing mechanism of a parasol or tent includes a frame, which includes an upper plate 1 and a lower plate 2. The upper plate 1 is provided with a plurality of long support bones 5 for supporting a sunshade cloth (not shown in the figure), and the lower plate 2 is provided with a plurality of short support bones 6, and one short support bone 6 is connected to one long support bone 5. The upper plate 1 and the lower plate 2 are connected by a gas spring 4. By opening the gas spring 4, the upper plate 1 and the lower plate 2 are moved away from each other to open the frame for sunshade. By contracting the gas spring 4, the upper plate 1 and the lower plate 2 are moved closer to each other to close the frame.

[0023] In this specific embodiment, a mounting end is respectively provided on the cylinder body 401 of the gas spring 4 and the protruding end of the piston rod 402 of the gas spring 4. The two mounting ends are arranged opposite to each other along the moving direction of the piston rod 402 of the gas spring 4. One of the mounting ends is fixedly connected to the upper disk body 1, and the other mounting end is fixedly connected to the lower disk body 2.

[0024] In this embodiment, the upper plate 1 and the lower plate 2 are connected by a connecting rod 3, which includes a first rod 301 and a second rod 302, which are coaxially and telescopically arranged. The upper plate 1 is fixedly mounted on the first rod 301, and the lower plate 2 is fixedly mounted on the second rod 302. The gas spring 4 is disposed within the connecting rod 3. The connecting rod 3 serves, firstly, to improve the overall connection and operational rigidity, and secondly, to allow the gas spring 4 to be integrally mounted within the connecting rod 3. The connecting rod 3 protects the gas spring 4 and increases its overall service life.

[0025] In this embodiment, each mounting end is provided with a mounting portion 40, one of which is fixedly connected to the second rod 302 via a first fixing member, and the other mounting portion 40 is fixedly connected to the first rod 301 or the upper plate 1 via a second fixing member. This achieves stable mounting of both ends of the gas spring 4, thereby ensuring its stable function.

[0026] In this specific embodiment, the first fixed connection member includes a first connecting tube 42 that is threaded and installed on the corresponding mounting portion 40. The two ends of the first connecting tube 42 extend out of the corresponding mounting portion 40 and are threaded and installed on the second rod body 302. The two ends of the first connecting tube 42 are respectively provided with first internally threaded connection holes (not marked in the figure). A first connecting bolt 8 that matches the first internally threaded connection hole is inserted from the outside of the second rod body 302 and threaded into the corresponding first internally threaded connection hole to achieve a fixed connection between the corresponding mounting portion 40 and the second rod body 302. The structure is simple, easy to install and disassemble, low cost, and stable connection; one mounting end of the gas spring 4 can be stably installed in the second rod body 302, and the lower plate 2 is fixed to the second rod body 302, which is equivalent to the fixed connection between the gas spring 4 and the lower plate 2.

[0027] In this embodiment, a fixing ring 7 is mounted on the exterior of the second rod 302 at the location corresponding to the first fixed connector. A first connecting bolt 8 passes through the fixing ring 7 and the corresponding wall surface of the second rod 302, threaded into the corresponding first internally threaded connection hole. The fixing ring 7 serves to enhance the rigidity of the connection. When the umbrella or tent body is used as a hanging umbrella, the bottom of the fixing ring 7 is sealed and installed at the bottom of the second rod 302, thereby sealing the bottom of the second rod 302.

[0028] In this specific embodiment, the second fixing member includes a second connecting tube 44 that is threaded onto the corresponding mounting portion 40. Both ends of the second connecting tube 44 extend from the outside of the corresponding mounting portion 40. The corresponding mounting portion 40 extends upward from the first rod 301 and extends into the upper plate 1. Both ends of the second connecting tube 44 are threaded onto the upper plate 1. Second internally threaded connection holes (not labeled) are provided at the two ends of the second connecting tube 44. Second connecting bolts 9 that cooperate with the second internally threaded connection holes extend from the outside of the upper plate 1 and are threaded into the corresponding second internally threaded connection holes to achieve a fixed connection between the corresponding mounting portion 40 and the upper plate 1. The structure is simple, easy to install and disassemble, low in cost, and stable in connection. One mounting end of the gas spring 4 can be stably fixed to the upper plate 1, and a fixed connection between the mounting end of the gas spring 4 and the upper plate 1 and the first rod 301 is simultaneously achieved through a single structure.

[0029] In this embodiment, the gas spring 4 is driven by a pull-wire switch 400, which is arranged on the outside, so as to facilitate the opening and closing operation of the sunshade portion from the outside.

[0030] The pull wire on the pull wire switch 400 can be hidden and passed through one of the support bones, and the switch body of the pull wire switch 400 can be installed at the outer end of the support bone for easy operation by the user.

[0031] In this specific embodiment, the gas spring 4 can be directly purchased from the market, for example, the controllable and lockable gas spring produced by Taizhou Youtai Auto Parts Co., Ltd. can be used.

[0032] When the sunshade needs to be opened, the control valve of gas spring 4 is opened through the pull-wire switch 400. After the control valve is opened, gas spring 4 is in a free expansion and contraction state, releasing the kinetic energy stored in gas spring 4 to open the sunshade. After the sunshade is fully opened, the pull-wire switch is released, and the position of the piston rod 402 of gas spring 4 is locked, thus achieving easy opening of the entire sunshade. To close the sunshade, the pull-wire switch 400 is pulled. The pull-wire switch 400 opens the control valve of gas spring 4, allowing gas spring 4 to retract freely and provide a little assistance to the frame. The gravity and potential energy of the frame, sunshade cloth, etc., work together to offset the elastic force of gas spring 4 and store the force in gas spring 4 for the next opening of the sunshade. While utilizing the gravity of the frame, it is necessary to consider the travel distance of the upper and lower discs 2 when opening and closing the sunshade (because the travel distance of gas spring 4 is too long, which would significantly increase the cost). Therefore, this product adopts the technology of reverse support of the umbrella surface, which significantly shortens the travel distance of gas spring 4 and makes the overall solution feasible.
