Description

Technical Field

[0001] This utility model relates to the field of sun umbrellas, specifically a structure that helps open a sun umbrella. Background Technology

[0002] In daily life, especially during outdoor activities such as on beaches, squares, entertainment venues, and roadside stalls, outdoor umbrellas are an essential tool. They can provide shade and protection from wind and rain. Outdoor umbrellas are usually large and tall, so opening and closing them requires pushing with both hands and pulling on the umbrella ribs. Due to the increased size and weight and the height of the umbrella pole, the operation is cumbersome, time-consuming, laborious, and inefficient.

[0003] Chinese patent CN219422358U discloses a structure for opening a straight-bar sun umbrella with a gas spring assist, including the sun umbrella body and an assist structure. The assist structure is a gas spring, which is threadedly connected to a gas spring bracket. The gas spring bracket is threadedly connected to a long umbrella rib and a short umbrella rib respectively. The top rod of the gas spring is kept in a state of minimum retraction. This patent places the gas spring between the long and short umbrella ribs, which solves the problem of saving effort to a certain extent, but it is not stable enough and often breaks down. Moreover, when the short umbrella rib is too long, the installation length of the gas spring is too long in order to use the gas spring, resulting in increased costs. Therefore, it is necessary to design a sun umbrella opening assist structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a structure that assists in opening a sunshade umbrella, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sunshade umbrella opening assistance structure, including a column, an upper umbrella plate fixedly installed on the top surface of the column, a plurality of long umbrella ribs hinged to the outer side of the upper umbrella plate, an assistance component provided between the long umbrella ribs and the column, and an umbrella opening component connected to the long umbrella ribs provided on the outer side of the column.

[0006] The power assist assembly includes two gas springs. One end of each gas spring is rotatably connected to the bottom of the long umbrella rib, and the other end is rotatably connected to the outside of the column. The two gas springs are symmetrical about the column.

[0007] Preferably, the umbrella opening assembly includes a lower umbrella disc sleeve, a lower umbrella disc, and multiple short umbrella ribs. The lower umbrella disc sleeve is slidably installed on the outside of the upright. The lower umbrella disc is fixedly installed on the upper outer side of the lower umbrella disc sleeve. One end of each short umbrella rib is hinged to the lower umbrella disc, and the other end of each short umbrella rib is hinged to a long umbrella rib.

[0008] Preferably, the short ribs are evenly distributed at equal intervals on the outer side of the lower umbrella disc, and the long ribs are evenly distributed at equal intervals on the outer side of the upper umbrella disc. The number of short ribs and long ribs are the same and their positions correspond one-to-one.

[0009] Preferably, two gas spring brackets A are symmetrically installed on the outer side of the column, and two gas spring brackets B are symmetrically installed on the sides of the two long umbrella ribs. Both gas spring brackets A and B have chamfered hexagonal screws on their inner sides. The upper and lower ends of the gas spring are rotatably connected to the chamfered hexagonal screws on the inner sides of the gas spring brackets B and A, respectively.

[0010] Preferably, the gas spring bracket A is fixed to the outside of the column by a pop rivet, and the gas spring bracket B is fixed to the side of the long umbrella rib by a pop rivet.

[0011] Preferably, both the gas spring bracket A and the gas spring bracket B have protrusions on their surfaces.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The umbrella opening assist structure of this sunshade features a control mechanism that allows the lower umbrella plate and lower umbrella plate to be pushed upwards during opening. With the large elongation force of the gas spring, the short and long umbrella ribs move upwards. The user only needs to apply a little force to drive the components upwards, thus easily opening the umbrella canopy. After the umbrella canopy is in place, the sunshade pin passes through the preset positioning hole on the upright to keep the umbrella canopy open. It is convenient to open the umbrella, and even if the umbrella canopy is too heavy, the umbrella can be easily opened by the gas spring.

[0014] 2. The umbrella opening assist structure, when closing the umbrella, controls the lower umbrella plate segment and slides downwards. Under the weight of the umbrella ribs and canopy, it offsets part of the resistance of the gas spring's extension, gently moving the lower umbrella plate to complete the closing. The gas spring bracket surface has protrusions to prevent difficulty in reopening the umbrella due to the gas spring's self-locking after closing. During this process, the outward extension of the gas spring's top rod provides cushioning, effectively preventing the canopy from closing too quickly due to the weight of the umbrella frame itself, thus reducing safety hazards. Furthermore, because the gas spring is connected to the upright and long umbrella ribs, it avoids using a longer gas spring for shorter umbrella ribs, reducing production costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please refer to Figure 1-4 As shown, this utility model provides a sunshade umbrella opening assistance structure, including a column 1, an upper umbrella plate 2 fixedly installed on the top surface of the column 1, a plurality of long umbrella ribs 3 hinged to the outside of the upper umbrella plate 2, an assistance component between the long umbrella ribs 3 and the column 1, and an umbrella opening component connected to the long umbrella ribs 3 on the outside of the column 1.

[0022] The power assist assembly includes two gas springs 7. One end of the gas spring 7 is rotatably connected to the bottom of the long umbrella rib 3, and the other end of the gas spring 7 is rotatably connected to the outside of the column 1. The two gas springs 7 are symmetrical about the column 1.

[0023] Specifically, when opening the umbrella, the opening component is controlled to move upward. Under the large elongation force of the gas spring 7, the long umbrella rib 3 moves upward. The user only needs to apply a little force to drive the component upward, thus easily opening the umbrella. It is convenient to open the umbrella. Even if the umbrella is too heavy, the umbrella can be easily opened by the gas spring 7.

[0024] The umbrella opening assembly includes a lower umbrella plate sleeve 5, a lower umbrella plate 6, and multiple short umbrella ribs 4. The lower umbrella plate sleeve 5 is slidably installed on the outside of the upright 1. The lower umbrella plate 6 is fixedly installed on the upper outer side of the lower umbrella plate sleeve 5. One end of the short umbrella rib 4 is hinged to the outside of the lower umbrella plate 6, and the other end of the short umbrella rib 4 is hinged to the long umbrella rib 3. Multiple short umbrella ribs 4 are evenly distributed at equal intervals on the outside of the lower umbrella plate 6, and multiple long umbrella ribs 3 are evenly distributed at equal intervals on the outside of the upper umbrella plate 2. The number of short umbrella ribs 4 and long umbrella ribs 3 are the same and their positions correspond one-to-one. When opening the umbrella, the lower umbrella plate sleeve 5 and the lower umbrella plate 6 are pushed upward, causing the short umbrella ribs 4 and long umbrella ribs 3 to move upward, thereby opening the umbrella canopy.

[0025] Specifically: Two gas spring brackets A8 are symmetrically installed on the outer side of the column 1, and gas spring brackets B9 are symmetrically installed on the sides of the two long umbrella ribs 3. Both gas spring brackets A8 and B9 have chamfered hexagonal screws on their inner sides. The upper and lower ends of the gas spring 7 are rotatably connected to the chamfered hexagonal screws on the inner sides of the gas spring brackets B9 and A8, respectively. The gas spring bracket A8 is fixed to the outer side of the column 1 by pop rivets, and the gas spring bracket B9 is fixed to the side of the long umbrella ribs 3 by pop rivets. Both gas spring brackets A8 and B9 have protrusions 10 on their surfaces, which allows the gas spring 7 to rotate relative to the column 1 and the long umbrella ribs 3. The protrusions 10 on the surface of the gas spring brackets can prevent the gas spring 7 from being difficult to open again after the umbrella is closed due to its self-locking.

[0026] Working principle: This utility model is a structure that helps open a sun umbrella. When opening the umbrella, the lower umbrella plate sleeve 5 and the lower umbrella plate 6 are pushed upward. Under the large elongation force of the gas spring 7, the short umbrella rib 4 and the long umbrella rib 3 move upward. The user only needs to apply a little force to drive the components upward, thereby easily opening the umbrella. After the umbrella is in place, the sun umbrella pin passes through the preset positioning hole on the column 1 to keep the umbrella in place and open. It is convenient to open the umbrella. Even if the weight of the umbrella is too large, the umbrella can be easily opened by the gas spring 7.

[0027] When closing the umbrella, control the lower umbrella plate section 5 and the lower umbrella plate 6 to slide downwards. Under the weight of the umbrella ribs and the umbrella canopy, some of the resistance of the extension of the gas spring 7 is offset, and the lower umbrella plate is gently moved to finally close the umbrella. The surface of the gas spring bracket has a protrusion 10, which can prevent the umbrella from being difficult to open again after closing due to the self-locking of the gas spring 7. During this process, the outward extension of the top rod of the gas spring 7 effectively prevents the umbrella canopy from closing too quickly due to the weight of the umbrella frame itself, and reduces safety hazards. In addition, because the two gas springs 7 are symmetrically distributed, they are more stable and reliable than side installation, and the force is more even. The gas springs will not be too long due to the excessive distance between the umbrella ribs.
