Description

Technical Field

[0001] This utility model relates to a sunshade umbrella, specifically a hand-operated hanging umbrella. Background Technology

[0002] Sun umbrellas, as an outdoor leisure tool, are widely used in squares, beaches, parks, and courtyards, providing people with a comfortable space to cool off. Existing sun umbrellas are classified into two types based on their structure: center-pillar umbrellas and hanging umbrellas. Hanging umbrellas, also known as side umbrellas or patio umbrellas, are generally large outdoor umbrellas with a large canopy area, making them relatively difficult to open and close.

[0003] There are generally two ways to open and close the canopy of existing hanging umbrellas. One is to use the umbrella rope to control the opening and closing of the canopy through a crank rope winding mechanism, and the other is to use a scissor-type linkage mechanism to control the opening and closing of the canopy. The above two methods have the following drawbacks: the first method has a long operation time and a complex product structure. The entire opening and closing function of the sun umbrella is achieved through a single rope, which poses a safety hazard. The second method often cannot provide sufficient height off the ground after the canopy is closed, which affects the layout of outdoor furniture such as tables and chairs.

[0004] An investigation revealed that Chinese patent CN202421410689.0, entitled "A Manually Openable and Closed Umbrella," includes a column, a diagonal bar, a crossbar, an upper umbrella canopy, a lower umbrella canopy, long umbrella ribs, and short umbrella ribs. The column has a slider that can slide vertically and vertically. The lower end of the crossbar is pivotally connected to the slider, and the upper end is pivotally connected to the upper umbrella canopy. The key feature is that it also includes a support rod and a strut. The upper end of the diagonal bar is pivotally connected to the top of the column, the middle part of the diagonal bar is pivotally connected to the lower middle part of the crossbar, the lower end of the diagonal bar is pivotally connected to the support rod, the other end of the support rod is pivotally connected to the middle part of the strut, the upper end of the strut is pivotally connected to the upper middle part of the crossbar, and the lower end of the strut is pivotally connected to the lower umbrella canopy. The crossbar, diagonal bar, support rod, and strut together form a quadrilateral linkage mechanism that allows the umbrella to open and close with reduced effort. While this umbrella is manually openable and closes, and improves upon some effort-saving features, it is not ideal and requires further refinement. Utility Model Content

[0027] The specific structure is as follows: the crossbar 3, diagonal bar 2, support bar 8, and strut 9 are all U-shaped metal tubing. The quick-release and assembly pivot connection structure between the long umbrella rib 6 and the upper umbrella nest 4 is as follows: multiple connectors 41 are fixed to the edge of the upper umbrella nest 4. The width of the connector 41 is not greater than the width of the U-shaped groove of the upper umbrella rib 6. The connector 41 has an arc surface and an upwardly inclined sliding groove 42. The upper end of the long umbrella rib 6 is an arc shape corresponding to the connector 41. A pin 61 that mates with the sliding groove 42 of the connector 41 is transversely inserted into the upper end of the upper umbrella rib 6. The long umbrella rib 6 is inserted into the sliding groove 42 through the pin 61 and connects with the upper umbrella nest 41. The umbrella nest 4 enables quick assembly and disassembly. The quick assembly and disassembly pivot structure between the short umbrella rib 7 and the lower umbrella nest 5 is based on the same principle as the pivot structure between the long umbrella rib 6 and the upper umbrella nest 7. Multiple connectors 51 are fixed on the edge of the lower umbrella nest 5. The width of the connector 51 is not greater than the width of the U-shaped groove of the short umbrella rib 7.

The short umbrella rib 7 can be quickly assembled and disassembled with the lower umbrella nest 5 by inserting the pin into the sliding groove 52.

[0028] A connector 11 is fixedly installed at the top of the column 1. The upper end of the diagonal rod 2 is pivotally connected to the connector 11 at the top of the column 1. A slider 12 that can slide vertically is provided on the column 1. The lower end of the crossbar 3 is pivotally connected to the slider 12. A pulley is provided inside the slider 12. At least one track 1a is formed on the side of the column 1 for the pulley to be inserted and slide vertically. In this embodiment, the track 1a is a concave track with a T-shaped cross-section. The cross-section of the column 1 is square, and all four sides of the column 1 are formed with tracks 1a for mounting umbrella canopies.

[0029] The column 1 is equipped with an electrical control module 20 and a battery unit 30 for controlling the movement of the linear motor 10. The electrical control module 20 is electrically connected to the battery unit 30 through a wireless sensing module 40 or through a wire 50.

[0030] The specific structure of the pivot connection between the middle part of the diagonal bar 2 and the lower part of the crossbar 3 is as follows: the width of the crossbar 3 is greater than the width of the diagonal bar 2. A strip-shaped slot 31 is provided along the length of the lower part of the crossbar 3 for the diagonal bar 2 to pass through and rotate. Through-hole pin holes are provided on the lower left and right sides of the strip-shaped slot 31. A corresponding through hole is provided in the middle of the diagonal bar 2. The diagonal bar 2 passes through the strip-shaped slot 31 and is pivotally connected to the crossbar 3 via the first connecting pin a. The width of the support rod 9 is the same as that of the diagonal bar 2. Through-hole pin holes are provided on the upper left and right sides of the strip-shaped slot 31 of the crossbar 3. A corresponding connecting through hole is provided at the upper end of the support rod 9. The upper end of the support rod 9 is inserted into the strip-shaped slot 31 and pivotally connected to the crossbar 3 via the second connecting pin b. The distance between the first connecting pin a and the second connecting pin b corresponds to the length of the support rod 8.

[0031] The inner wall width of the support rod 8 is not less than the outer wall width of the diagonal rod 2 and the strut 9. During installation, the U-shaped openings of the horizontal rod 3, diagonal rod 2, and strut 9 face downwards, and the U-shaped opening of the support rod 8 faces upwards. Pin holes are opened at both ends of the support rod 8, and corresponding through holes are opened at the lower end of the diagonal rod 2 and the middle part of the strut 9. They are pivotally connected together by a pivot pin.

[0032] The lower end of the linear motor 10 is provided with a connecting block 101 that mates with the U-shaped opening of the support rod 8. The connecting block 101 has a through hole, and the lower part of the support rod 8 has a corresponding connecting hole. The lower end of the linear motor 10 is inserted into the U-shaped opening of the support rod 8 through the connecting block 101 and is pivotally connected to the support rod 8 through a pin. The upper end of the linear motor 10 is connected to the middle part of the inclined rod 2.

[0033] Detachable light strips 60 and 70 are installed on the long umbrella ribs 6 and 7 respectively. Similarly, a detachable light panel 50 is installed on the lower umbrella nest 5. The detachable structure of the light strips and umbrella ribs and the detachable structure of the light panel and lower umbrella nest can be various conventional structures, such as snap-fit ​​or magnetic fixation, etc.

[0034] In addition, the drive structure is not limited to the linear motor 10, and a gas spring can also be used.

[0035] The following explanation uses a long umbrella rib (6) as an example to illustrate the installation of the umbrella ribs. Figure 6 As shown, the long umbrella rib 6 is moved linearly along the angle of the groove 42 on the connector 41. The pin 61 slides into the groove 42 of the connector 41 until the end. Then, the long umbrella rib 6 is rotated around the pin 61 to complete the assembly. At this time, the inner wall of the long umbrella rib 6 abuts against the arc surface of the connector 41, and the pin 61 abuts against the inclined surface of the connector 41. Under normal use, the long umbrella rib 6 cannot reach the inclined angle of the connector 41. Therefore, the long umbrella rib 6 can only rotate relative to the pin 42 and cannot fall off the connector 41.

[0036] The working principle is as follows: When the linear motor 10 starts, the distance between the two ends increases. Under the drive of the quadrilateral linkage mechanism, the support rod 9 also moves upward and the crossbar 3 moves from a near-vertical state to a near-horizontal state, thereby raising the height of the lower umbrella nest 5 to complete the opening of the umbrella. After the umbrella is closed, the end of the umbrella rib is higher off the ground, which makes it convenient to place furniture such as tables and chairs.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
