Description

[0001] The utility model relates to the technical field of outdoor parasols, in particular to a novel, height-adjustable outdoor parasol that can be opened and closed.

[0002] Outdoor parasols are widely used as recreational equipment—for example, in squares, beaches, parks, or gardens—to provide pleasant shade. Current outdoor parasols generally differ depending on the positioning of their canopies: hanging parasols or center-pole parasols. Hanging parasols, due to their side-hung canopies, offer larger areas underneath, which increases their utility value.

[0003] A traditional canopy umbrella consists of a base pole and a canopy assembly. The canopy assembly consists of the center pole, cross poles, top panel, bottom panel, and canopy. When the umbrella is folded, the height of the top panel remains unchanged, while pulling up the bottom panel folds the cross poles, allowing the umbrella to be folded. Currently, parasols with large canopies are available on the market. Due to the large canopy area, the umbrella frames are close to the ground when folded, which means that tables or objects underneath the umbrella are easily touched during opening and folding. However, if the canopy is mounted too high, sun protection is no longer guaranteed.

[0004] In addition, Roman parasols with side poles have two different opening and closing mechanisms: On the one hand, a crank mechanism is used to pull the parasol rope together, thus opening and closing the parasol canopy; on the other hand, a cross-parasol pole structure is used, in which the parasol canopy is opened and closed by changing the cross poles.

[0005] For example, the document with the publication number CN213154477U discloses a moving base with a sliding opening and closing structure and an outdoor umbrella, comprising a handrail housing for slidingly collaborating with the side post, wherein a locking point is attached to the top of the side post and a bottom stop is attached to the bottom of the side post. When the handrail housing slides on the side post to the highest position, it actuates the outdoor umbrella to open and locks itself at the locking point of the side post; when the handrail housing slides to the lowest position, it actuates the outdoor umbrella to close and abuts the bottom stop. The present utility model provides a handrail housing, and the umbrella canopy assembly is opened and closed by sliding up and down on the side post.This is characterized by a simple structure, easy assembly, user-friendly operation and low production costs.

[0006] However, in this type of outdoor parasols, during long-term use, the cross structure between the upper diagonal pull rod and the lower diagonal pull rod often causes the umbrella fabric at this point to be stressed by the scissor-like force from the cross movement between the upper diagonal pull rod and the lower diagonal pull rod when unfolding, which causes damage to the umbrella fabric and significantly affects its service life.

[0007] Regarding the above-mentioned problem, the present utility model aims to provide a novel, height-adjustable outdoor parasol that can be opened and closed. The overall structure is optimized by using a drive device that synchronously drives both the height-adjustable parasol pole and the movement base, enabling simultaneous opening and closing, as well as raising and lowering of the parasol frame. Furthermore, the optimized use of a hinge bearing is provided to prevent damage to the parasol fabric.

[0027] In order to better understand the technical means, design features and achieved objectives and effects realized by the present utility model, a further explanation of the present utility model is given below in conjunction with concrete figures. Example 1

[0028] With reference to Fig. 1 up to Fig. 14, a novel openable and collapsible, height-adjustable outdoor parasol is provided in the present utility model, comprising an umbrella pole 100, a cross umbrella rod 300 and an umbrella frame 600, wherein the umbrella frame 600 is a conventional umbrella frame according to the prior art, wherein the umbrella frame 600 comprises an upper umbrella plate 610, a lower umbrella plate 620, a plurality of long umbrella ribs 601 and short umbrella ribs 602, wherein the cross umbrella rod 300 consists of a first cross umbrella rod 310 and a second cross umbrella rod 320, wherein one end of the first cross umbrella rod 310 acts like a hinge with the movement base 200 in the umbrella pole 100, while the other end acts like a hinge with the upper umbrella plate 610 in the umbrella frame 600, wherein one end of the second cross umbrella rod 320 is connected to the upper end of the umbrella mast 100 acts like a hinge,while the other end acts as a hinge with the lower umbrella plate 620 in the umbrella frame 600, wherein the first cross umbrella rod 310 and the second cross umbrella rod 320 in the cross umbrella rod 300 are arranged in an "X"-shaped arrangement, wherein the "X" shape between the first cross umbrella rod 310 and the second cross umbrella rod 320 is changed by the up and down movement of the movement base 200, thereby realizing the opening and closing of the umbrella frame 600.

[0029] Preferably, the umbrella pole 100 comprises a fixed umbrella pole 101 and a height-adjustable umbrella pole 102, wherein a movement sliding groove 104 is attached to the fixed umbrella pole 101, wherein a movement base 200 moves up and down along the movement sliding groove 104 by means of a drive device 400 to enable the umbrella frame 600 to be folded and unfolded. The drive device 400 is further capable of moving the height-adjustable umbrella pole 102 to adjust the height of the parasol; when the umbrella frame 600 moves from the folded to the unfolded state, the drive device 400 drives the movement base 200 to move upward along the movement sliding groove 104, and at the same time, the drive device 400 causes the height-adjustable umbrella pole 102 to lower.when the umbrella frame 600 moves from the unfolded to the folded state, the drive device 400 drives the moving base 200 to move downward along the moving sliding groove 104, and at the same time, the drive device 400 causes the height-adjustable umbrella pole 102 to increase;The overall structure is optimized by the drive device 400 synchronously driving both the movable base 200 and the height-adjustable umbrella pole 102, with the upward and downward movements of the movable base 200 and the height-adjustable umbrella pole 102 running in opposite directions. As a result, when the umbrella frame 600 is unfolded, the movable base 200 is in a high position and the height-adjustable umbrella pole 102 is in a low position, ensuring that the umbrella frame 600 reaches a normal unfolded height after folding. When the umbrella frame 600 is folded, the movable base 200 is in a low position and the height-adjustable umbrella pole 102 is in a high position, ensuring that the folded umbrella frame 600 is relatively raised to prevent damage to the lower area due to impact.

[0030] In connection with the above points, the drive device 400 comprises an operating device 410, a coupling element 420, a roller group, and an umbrella pole base 440. The coupling element 420 preferably consists of a circulating cable, the circulating cable typically being an umbrella cable or a steel wire rope to enable a cyclical circulating movement. Alternatively, chains or similar substitute products can also be used. The coupling element 420 is firmly connected to the umbrella pole base 440, the coupling element 420 is firmly connected to the movement base 200, the coupling element 420 being adaptably mounted on the roller group, the operating device 410 serving to drive the coupling element 420 along the roller group in a reciprocating cyclic movement, thereby moving the umbrella pole base 440 and the movement base 200.The coupling element 420, in combination with the operating device 410 and the roller group, implements a cyclical arrangement. Due to the cyclical movement of the coupling element 420 under the action of the operating device 410, the movement base 200 and the umbrella pole base 440, which are firmly connected in the coupling element 420, implement a positioning movement corresponding to the cyclical movement of the coupling element 420. The movement base 200 and the umbrella pole base 440 are located on opposite sides of the cyclical rotation of the coupling element 420 and thus form opposite movement paths.

[0031] In the specific structure, the umbrella pole base 440 is attached to the height-adjustable umbrella pole 102, wherein the umbrella pole base 440 is preferably arranged on the outer side wall of the height-adjustable umbrella pole 102, wherein the height-adjustable umbrella pole 102 is embedded in the interior of the fixed umbrella pole 101, wherein the height-adjustable umbrella pole 102 executes an upward and downward movement along the upper interior of the fixed umbrella pole 101. With the cyclical movement of the coupling element 420, the umbrella pole base 440 is placed in a position to move the height-adjustable umbrella pole 102 along with it, executing an upward and downward movement.The height-adjustable umbrella pole 102 comprises a height-adjustable umbrella pole body and a sub-umbrella pole base 140 located in the lower region of the height-adjustable umbrella pole body. The height-adjustable umbrella pole body and the sub-umbrella pole base 140 are internally hollow in structure and have interior spaces. Rollers 141 are attached to the side surface of the sub-umbrella pole base 140. The rollers 141 serve to slide against the interior wall of the fixed umbrella pole 101. For the optimized arrangement of the sub-umbrella pole base 140, in conjunction with rollers 141, an easier up and down movement of the height-adjustable umbrella pole 102 within the interior of the fixed umbrella pole 101 is enabled, whereby the smoothness of the up and down movement is improved.

[0032] In connection with the above-mentioned points, a cover cap 110 is attached to the upper part of the height-adjustable umbrella pole body. Umbrella pole eyelets 111 are provided on the cover cap 110. The umbrella pole eyelets 111 serve to hinge-like fit with one end of the second cross umbrella pole 320. The cover cap 110 is firmly connected to the upper part of the height-adjustable umbrella pole body and is located at the top of the height-adjustable umbrella pole body. Due to the hinge-like connection of the umbrella pole eyelets 111 in the cover cap 110 to the second cross umbrella pole 320, the hinge point of the second cross umbrella pole 320 is displaced upward when the height-adjustable umbrella pole 102 is raised, whereby the entire umbrella frame 600 can be raised after folding.Conversely, when lowering, the hinge point of the second parasol pole 320 is moved downwards, which causes the parasol frame 600 to be lowered after unfolding.

[0033] In connection with the above points, a height-adjustable chamber groove 107 is arranged at the top of the fixed umbrella pole 101, wherein an upper umbrella pole holder 120 is additionally attached to the upper part of the fixed umbrella pole 101, wherein an umbrella pole through-hole 121 is attached to the upper umbrella pole holder 120, wherein the umbrella pole through-hole 121 serves to pass and move the height-adjustable umbrella pole 102, wherein the up and down movement of the height-adjustable umbrella pole 102 is facilitated by means of the umbrella pole through-hole 121 and the chamber groove 107.

[0034] In the specific structure, the roller group consists of an upper roller base 430 and a lower roller base 450, wherein the upper roller base 430 is typically mounted on the upper part of the fixed umbrella pole 101, and the lower roller base 450 is mounted on the bottom of the fixed umbrella pole 101. The upper roller base 430 and the lower roller base 450 form two enclosing pivot points at the top and bottom, which enable the coupling element 420 to perform a circumferential movement up and down.

[0035] In the special structure, the coupling element 420 extends from the operating device 410 along the inner cavity of the fixed umbrella pole 101 upwards, penetrates the lower umbrella pole inner cavity 140 and extends into the height-adjustable umbrella pole body inner cavity, wherein height-adjustable umbrella pole body penetrating holes 103 extend outwardly on the outside of the umbrella pole body and are firmly mounted on the umbrella pole base 440 in order to facilitate subsequent cooperation with the upper roller base 430 and to avoid interference when moving the height-adjustable umbrella pole 102 up and down, wherein the coupling element 420 extends continuously upwards to the upper roller base 430, wraps around the upper roller 431 in the upper roller base 430 and then extends downwards to the moving base 200, wherein the coupling element 420 is firmly mounted on the moving base 200 is mounted,wherein the lower part of the movement base 200 cooperates with the lower roller base 450 through the coupling element 420, wherein the coupling element 420 wraps around the lower roller 451 in the lower roller base 450 and then extends upwards to the operating device 410,thereby forming a closed circuit. The entire circulation line of the coupling element 420 is optimized; in this case, the coupling element 420 can be connected either segmentally or as a continuous cable during fixed installation on the movement base 200 and the umbrella pole base 440. In the specific embodiment, the coupling element 420 is attached to both the upper and lower ends of the movement base 200 by means of a cable knot head 421; the coupling element 420 uses a segmental connection structure, and in a specific structure, the coupling element 420 penetrates the umbrella pole base 440, and the coupling element 420 is firmly connected there by means of a cable knot block 422 located in the umbrella pole base 440. The umbrella pole base 440 has a receiving groove 441, which serves toto receive the rope knot block 422; this rope knot block 422 is confined within the receiving groove 441 and can abut against the side wall of the receiving groove 441 during the movement of the rope knot block 422 in order to ensure a synchronous movement of the umbrella pole base 440.

[0036] In connection with the above points, the operating device 410 comprises a mounting base 411, a drive seat 412, a transmission seat 413 and an output seat 414, wherein the drive seat 412, the transmission seat 413 and the output seat 414 are installed in the mounting base 411, wherein the drive seat 412 comprises an input shaft 4121 and a drive gear 4122, wherein the transmission seat 413 comprises the first transmission gear 4131 and the second transmission gear 4132, wherein the first transmission gear 4131 serves to couple with the drive gear 4122, wherein the first transmission gear 4131 and the second transmission gear 4132 rotate synchronously, wherein the output seat 414 comprises the third transmission gear 4142 and a planetary gear 4141, wherein the third transmission gear 4142 is used to drive the planetary gear 4141 to rotate,A transmission coupling exists between the third transmission gear 4142 and the second transmission gear 4132, with the coupling element 420 being mounted circumferentially on the planetary gear 4141. In the actual operating process, the user rotates the input shaft 4121, whereby the input shaft 4121 causes the drive gear 4122 to rotate.

[0037] The drive gear 4122 transmits the rotational movement to the first transmission gear 4131, with the first transmission gear 4131 synchronously driving the second transmission gear 4132. The power transmission between the second transmission gear 4132 and the third transmission gear 4142 preferably takes place via a chain 415, which drives the third transmission gear 4142. An optimized gear ratio is provided between the second transmission gear 4132 and the third transmission gear 4142 to improve the gear ratio, reduce the rotational resistance of the input shaft 4121, and increase user-friendliness. The rotation of the third transmission gear 4142 causes the planetary gear 4141 to rotate. The planetary gear 4141 enables bilateral wrapping of the coupling element 420.End brackets 423 are attached to both ends of the coupling element 420, which serve to ensure appropriate limitations and locking with the idler gear 4141. Several idler grooves 4143 are located on the idler gear 4141, with both ends of the coupling element 420 circumferentially surrounding the idler groove 4143 and arranged laterally. The rotational movement of the idler gear 4141 causes winding at one end of the coupling element 420, while unwinding occurs at the other end, thereby realizing a complete revolution of the coupling element 420.

[0038] The mounting base 411 is embedded in the fixed umbrella pole 101, with a drive through-opening 106 provided on the fixed umbrella pole 101, wherein the drive through-opening 106 interacts accordingly with the input shaft 4121. The input shaft 4121 serves to couple to the hand crank handle, thereby enabling easy rotation of the input shaft 4121 by the hand crank handle. In other embodiments, the input shaft 4121 can also be combined with a drive motor, which causes a rotary movement by forward and reverse rotation of the input shaft 4121, thus realizing an overall through-drive.

[0039] In the specific structure, the moving base 200 comprises a moving base body 220 and an umbrella pole hinge bearing 210 attached to one side of the moving base body 220. The umbrella pole hinge bearing 210 serves to hinge-like fit with one end of the first parasol pole 310. Moving rollers 230 are provided on the moving base body 220, the moving rollers 230 serving to fit with the roller groove 105 in the moving sliding groove 104. By optimizing the structure of the moving base 200, mobility can be improved and the movement of the moving base 200 can be facilitated. In further embodiments, the moving base 200 can also have a handrail device, wherein the parasol rod is replaced by a boom and a tension arm, which, in combination with the umbrella frame, are suitable for use with Roman parasols.

[0040] These utility models optimize the overall structure by using a drive mechanism that synchronously drives both the height-adjustable umbrella pole and the moving base, enabling synchronous opening and closing, as well as raising and lowering of the umbrella frame. The drive mechanism is particularly optimized: the orbiting movement of a coupling element drives both the height-adjustable umbrella pole and the moving base. Raising or lowering the height-adjustable umbrella pole allows the umbrella frame to be raised when closing and lowered when opening, thus preventing interference under the umbrella caused by the umbrella frame when closing and maintaining an appropriate sunshade height after opening.By combining the movement base with a cross umbrella rod, the automatic lifting for opening or lowering for closing of the umbrella frame can be realized, which makes the handling of opening and closing the parasol considerably easier. Example 2

When the parasol is folded, the moving base 200 is usually located in the lower region of the umbrella pole 100, which moves upwards along the umbrella pole with the moving base 200, causing a position change between the first cross umbrella pole 310, resulting in an X-shaped deformation between the first cross umbrella pole 310 and the second cross umbrella pole 320. As the moving base 200 rises, the upper umbrella plate 610 and the lower umbrella plate 620 gradually approach each other at the other end, thereby realizing the unfolding of the umbrella frame 600. Conversely, a downward movement of the movement base 200 along the umbrella pole 100 causes the parasol to move from the opened to the closed state.

[0042] In connection with the above points, the cross-shade pole 310 is typically provided at both ends with a first mounting seat 312, a second mounting seat 313, and the first cross-shade pole body 311. The first mounting seat 312 is provided for hinge-like fitting with the movement base 200, while the second mounting seat 313 is provided for hinge-like fitting with the upper umbrella plate 610.

[0043] In connection with the above points, a cross groove 321 is arranged on the second cross-shade rod 320, wherein the first cross-shade rod 310 penetrates the cross groove 321, so that the first cross-shade rod 310 and the second cross-shade rod 320 form a cross structure. The cross groove 321 facilitates the X-shaped deformation between the first cross-shade rod 310 and the second cross-shade rod 320. A hinge bearing 330 is arranged on the first cross-shade rod 310, wherein the hinge bearing 330 is partially or wholly received in the cross groove 321, wherein the hinge bearing 330 serves for a hinge-like fit with the side wall of the cross groove 321.In particular, the hinge bearing 330 comprises a mounting base 332 and a hinge base 331. The mounting base 332 serves for fixed mounting on the upper surface of the middle part of the first cross-shade rod 310, the hinge base 331 being located above the mounting base 332. The hinge base 331 comprises two hinge side walls 333, the hinge side walls 333 interacting with the inner walls of the cross groove 321 in an opposing manner, so that the hinge bearing 330 forms an outwardly curved structure, thereby shifting the hinge point between the first cross-shade rod 310 and the second cross-shade rod 320 upward. The hinge point of the hinge bearing 330 with the cross groove 321 protrudes beyond the outer surface of the umbrella fabric 500. Due to a protruding design of the hinge bearing 330, the hinge point lies outside the umbrella fabric 500.This prevents the first cross umbrella pole 310 and the second cross umbrella pole 320 from exerting shear forces on the umbrella fabric 500 when the umbrella is opened and closed, which increases the service life of the umbrella fabric 500.

[0044] In the specific structure, a first hinge shaft hole 334 is arranged on the hinge side wall 333, and a second hinge shaft hole 328 is provided on the inner side wall of the cross groove 321, the first hinge shaft hole 334 and the second hinge shaft hole 328 being connected to each other by a hinge shaft, the hinge shaft being a component commonly used in the art, whereby a hinge structure is easily formed.

[0045] In connection with the above points, the second cruciform umbrella pole 320 comprises a first umbrella pole holder 323, a second umbrella pole holder 324 and the second cruciform umbrella pole body 322, wherein a first umbrella pole receptacle 325 is attached to the first umbrella pole holder 323, wherein a second umbrella pole receptacle 326 is attached to the second umbrella pole holder 324, wherein the first umbrella pole receptacle 325 is embedded in one end of the second cruciform umbrella pole body 322, wherein the second umbrella pole receptacle 326 is embedded in the other end of the second cruciform umbrella pole body 322. A cover cap 110 is attached to the upper part of the umbrella pole 100, wherein umbrella pole eyelets 111 are provided on the cover cap 110, wherein the umbrella pole eyelets 111 serve to hinge-like fit with one end of the first cruciform umbrella pole 323.An umbrella plate seat 621 is attached to the lower umbrella plate 620, and an umbrella pole hinge bearing 327 is provided on the second umbrella pole holder 324, the umbrella pole hinge bearing 327 serving to fit the umbrella plate seat 621 in a hinge-like manner and facilitating the assembly of the second cross umbrella pole 320.

[0046] In a preferred embodiment, the second cross umbrella pole body 322 is a one-piece structure.

[0047] In a preferred embodiment, the second cross umbrella pole body 322 comprises two second cross umbrella pole arms 3221 arranged parallel to one another and at a distance from one another, wherein reinforcing plates 3222 are connected between two cross umbrella pole arms 3221.

[0048] The present utility model optimizes the hinge structure of the first cross-shaped umbrella pole 310 and the second cross-shaped umbrella pole 320 by designing the hinge bearing 330 with a protruding hinge, placing the hinge point outside the umbrella fabric 500. This prevents the first cross-shaped umbrella pole 310 and the second cross-shaped umbrella pole 320 from exerting shear forces on the umbrella fabric 500 when the umbrella is opened and closed, thus increasing the service life of the umbrella fabric.

[0049] The embodiments described above represent only preferred embodiments of the present utility model application and are in no way to be understood as a limitation of the utility model in any form. QUOTES CONTAINED IN THE DESCRIPTION
