Description

Technical Field

[0001] The present invention belongs to the technical field of umbrellas and relates to a connection structure of the top cloth of an umbrella. Background Art

[0002] With the continuous improvement of people's living standards, more and more sunshades and the like are applied in our lives. They have a good sunshading and sunscreen effect on sunny days. During daily use, sometimes there will be strong wind weather. A single-layer sunshade is easily affected by strong winds and blown over or knocked down, resulting in inconvenient use of the sunshade.

[0003] In view of the above existing problems, various double-layer umbrellas have been developed by people:

[0004] For example, Chinese Patent Application (Patent Application No.: 200620101256.2) discloses a push-pull type hanging umbrella with an external column, which includes an umbrella column and an umbrella frame connected to the umbrella column. An umbrella surface is provided on the umbrella frame. An operating mechanism for opening and closing the umbrella frame and the umbrella surface is connected to the umbrella frame. One end of an umbrella rope is connected to the center of the lower part of the umbrella frame. The umbrella column is arranged outside the umbrella frame. The operating mechanism for opening and closing the umbrella frame and the umbrella surface is arranged on the umbrella column. The operating mechanism is set as a push-pull type operating mechanism. A canopy frame with a canopy is connected to the umbrella frame. The canopy frame includes a top plate arranged at the top end of a suspension rod. The top plate is movably hinged with a plurality of top rods. The top rods are movably hinged with a support rod. The support rod is movably hinged with the umbrella frame.

[0005] Although the above structure realizes the installation and fixation of the canopy by connecting a canopy frame to the umbrella frame, and the opening of the umbrella surface is achieved by extending the distance between the umbrella rope at the lower part of the umbrella frame and the sliding sleeve, making the umbrella rope tightened and one end of the umbrella rope connecting the umbrella frame lifted, thereby opening the umbrella frame. At this time, the opening and closing of the canopy are linked with the opening and closing of the umbrella frame. However, since the canopy frame is only hinged to the umbrella frame through a support rod and requires a plurality of top plates, top rods and support rods, the structure of the entire canopy frame is complex, and the overall weight of the entire umbrella frame is increased, raising the manufacturing cost of the entire hanging umbrella. Summary of the Invention

[0006] The object of the present invention is to provide a connection structure of the top cloth of an umbrella in view of the above existing problems in the prior art. The technical problem to be solved by the present invention is: how to solve the problems that the connection structure of the top cloth on the existing umbrella is complex and the manufacturing cost of the umbrella is relatively high.

[0007] The object of the present invention can be achieved by the following technical solutions:

[0008] The cam-shaped umbrella ribs are connected to the bottom of the umbrella ribs by the spring and the spring, and the cam-shaped umbrella ribs are connected to the bottom of the umbrella ribs by the spring and the spring.

[0009] Working principle: when in use, the upright support is spread open, and the upper umbrella rib is fixed on the upright support. At this time, the lower umbrella plate on the umbrella frame moves upward relative to the upper umbrella plate to open the umbrella, and the upper umbrella rib on the upper umbrella plate and the lower umbrella rib of the lower umbrella plate are opened accordingly. At this time, the connecting rod moves upward relative to the upper umbrella plate and drives the top plate to move upward. The top plate spreads the umbrella top cloth, and the umbrella top cloth drives the other end of the connecting block to swing upward until the limiting part abuts against the upper umbrella rib and can tighten the umbrella top cloth, thereby realizing the opening of the entire umbrella; when the umbrella needs to be folded, it is only necessary to move the lower umbrella plate downward relative to the upper umbrella plate to fold the umbrella. At this time, the umbrella top cloth has no pulling force on the connecting block, and the connecting block is closed along with the folding of the upper umbrella rib. The other end of the connecting block is swung downward to abut against the upper rib, so that the folding and unfolding of the entire umbrella only requires the operation of the umbrella frame, and only a top plate fixedly connected to the middle part of the umbrella top cloth is provided above the connecting rod, and one end of a plurality of connecting blocks is respectively hinged on the corresponding upper rib, so as to realize the folding and unfolding of the umbrella top cloth, avoids the increase of the overall weight of the umbrella and makes the overall structure of the umbrella more complicated as in the existing structure of the canopy frame, and the umbrella top cloth connection structure is simpler, the overall assembly and assembly are more convenient, and the manufacturing cost of the umbrella is also saved, and the lightweight design of the umbrella is realized.

[0010] In the umbrella top cloth connection structure mentioned above, one end of the connection block has a hinge groove for the upper rib to be embedded in, and the limiting portion is a limiting wall that can abut against the upper end of the upper rib, and the limiting wall is arranged on the hinge groove.

[0011] The arrangement of the hinge groove increases the stability of the connection of the connecting block, and during the swinging of the connecting block, the upper rib can limit the connecting block to a certain extent, and when the other end of the connecting block swings upward, the limiting wall on the connecting block can abut against the upper end surface of the upper rib to achieve the tensioning of the umbrella top cloth, thereby making the tensioning of the umbrella top cloth more convenient and simple, further simplifying the entire umbrella top cloth connection structure, and also realizing the lightweight design of the umbrella.

[0012] In the above umbrella top cloth connection structure of the umbrella, the groove walls on both sides of the hinge groove are flat surfaces, and the side walls on both sides of the umbrella rib are respectively attached to the groove walls on both sides of the hinge groove.

[0013] The setting of this structure enables the connection block to be limited by the side walls on both sides of the umbrella rib during the flipping process, avoiding the situation of jamming of the connection block during the flipping process, and further improving the stability of the use of the umbrella top cloth connection structure.

[0014] In the above umbrella top cloth connection structure of the umbrella, the connection block has a weight reduction cavity communicating with the hinge groove, and the opening of the weight reduction cavity faces downward. When the lower umbrella disk moves downward relative to the upper umbrella disk to close the umbrella, the other end of the connection block abuts against the upper end of the upper umbrella rib, and a part of the upper umbrella rib is located in the weight reduction cavity.

[0015] The setting of the weight reduction cavity can further improve the lightweight design of the connection block. And by making the opening of the weight reduction cavity face downward, when the other end of the connection block is not subjected to the pulling force of the umbrella top cloth, the other end of the connection block will swing downward under the influence of its own gravity until a part of the upper umbrella rib is located in the weight reduction cavity, and the side wall of the upper umbrella rib is attached to the cavity wall of the weight reduction cavity, thereby realizing the stable placement of the connection block when the umbrella is closed, and further improving the stability when the umbrella is closed.

[0016] In the above umbrella top cloth connection structure of the umbrella, hinge holes I are opened on the groove walls on both sides of the hinge groove, hinge holes II are opened on the umbrella rib opposite to the hinge holes I, the umbrella top cloth connection structure further includes a hinge screw and a nut, and one end of the hinge screw sequentially passes through the hinge hole I and the hinge hole II and is fixedly connected with the nut.

[0017] The setting of the hinge holes I and the hinge holes II makes the connection of the connection block more convenient and simple, and further simplifies the umbrella top cloth connection structure.

[0018] In the above umbrella top cloth connection structure of the umbrella, the other end of the connection block has a connection column, an installation hole penetrating through the top surface of the connection block is opened on the connection column, and the connection column is located inside the connection block.

[0019] The setting of this structure enables the umbrella top cloth to be fixedly connected with the connection column in the connection block through a fastener. At this time, the entire umbrella top cloth is located above the connection block, making the supporting effect between the connection block and the umbrella top cloth better and improving the stability of the connection of the umbrella top cloth.

[0020] In the above umbrella top cloth connection structure of the umbrella, the umbrella top cloth is connected with the connection column through a fastener passing through the installation hole, and an annular umbrella surface pressing piece is provided between the umbrella top cloth and the fastener.

[0021] The arrangement of this structure can add a circular umbrella surface pressing piece between the umbrella top cloth and the fastener, which can more stably press the umbrella top cloth onto the connecting block, and further improve the stability of the umbrella top cloth connection.

[0022] In the above-mentioned umbrella top cloth connection structure, the upper end surface of the connection block is a curved surface.

[0023] The arrangement of this structure makes it difficult for the connection block to scratch the umbrella top cloth during the flipping process, and is also convenient for users to store and access, further improving the safety of the use of the hanging umbrella.

[0024] In the umbrella top cloth connection structure of the above umbrella, there are four connection blocks, and eight umbrella ribs. The four connection blocks are hinged to four of the umbrella ribs respectively.

[0025] The connecting blocks can be hinged to the umbrella ribs at intervals in sequence, and the setting of the number of connecting blocks makes the installation of the umbrella top cloth more stable.

[0026] In the umbrella top cloth connection structure of the above-mentioned umbrella, the limiting part is a limiting rod arranged on the connecting block, and the upper umbrella rib is provided with a limiting groove for the limiting rod to slide and limit. When the connecting rod moves upward relative to the upper umbrella plate, the limiting rod abuts against the groove wall of the limiting groove and limits the other end of the connecting block from swinging toward the connecting rod.

[0027] The limiting rod and the limiting groove cooperate to achieve the limiting of the connection block, so that the stroke of the connection block can be controlled when it swings, and the limiting of the umbrella top cloth can be achieved.

[0028] Compared with the prior art, the umbrella top cloth connection structure of the present umbrella has the following advantages:

[0029] 1. Only a top plate fixedly connected to the middle part of the umbrella top cloth is arranged above the connecting rod, and one end of a plurality of connecting blocks is respectively hinged on the corresponding upper umbrella ribs, so as to realize the retraction and deployment of the umbrella top cloth, avoid the increase of the overall weight of the umbrella by the existing structure of the canopy frame, and make the overall structure of the umbrella more complicated, while the umbrella top cloth connection structure is simpler, the overall assembly and assembly are more convenient, and the manufacturing cost of the umbrella is also saved, and the lightweight design of the umbrella is realized.

[0030] 2. The setting of the hinge groove increases the stability of the connection of the connecting block, and when the connecting block swings, the upper rib can limit the connecting block to a certain extent, and when the other end of the connecting block swings upward, the limiting wall on the connecting block can achieve the tensioning of the umbrella top cloth by abutting against the upper end surface of the upper rib, thereby making the tensioning of the umbrella top cloth more convenient and simple, further simplifying the entire umbrella top cloth connection structure, and also realizing the lightweight design of the umbrella.

The top plate 11 opens the umbrella top cloth 5, and the umbrella top cloth 5 pulls the other end of the connecting block 4 to swing upward until the limiting part abuts against the upper umbrella rib 23 and can tighten the umbrella top cloth 5, thereby realizing the opening of the entire umbrella; when it is necessary to fold the umbrella, it is only necessary to move the lower umbrella plate 22 downward relative to the upper umbrella plate 21 to fold the umbrella. At this time, the umbrella top cloth 5 has no pulling force on the connecting block 4. As the upper ribs 23 are folded, the other end of the connecting block 4 swings downward to abut against the upper ribs 23, so that the folding and unfolding of the entire umbrella only requires the operation of the umbrella frame 2, and only a top plate 11 fixedly connected to the middle part of the umbrella top cloth 5 is provided above the connecting rod 3, and one end of several connecting blocks 4 is respectively hinged on the corresponding upper ribs 23, thereby realizing the folding and unfolding of the umbrella top cloth 5, avoiding the increase in the overall weight of the umbrella and making the overall structure of the umbrella more complicated as in the existing structure of the canopy frame. The connection structure of the umbrella top cloth 5 is simpler, the overall assembly and assembly are more convenient, and the manufacturing cost of the umbrella is saved, realizing the lightweight design of the umbrella.

[0042] like Figures 2-5 As shown, one end of the connecting block 4 is provided with a hinge groove 41 for the upper rib 23 to be embedded in, and a limiting wall 42 at a limiting position that can abut against the upper end of the upper rib 23, and the limiting wall 42 is arranged on the hinge groove 41, and the groove walls on both sides of the hinge groove 41 are flat, and the side walls on both sides of the upper rib 23 are respectively fitted with the groove walls on both sides of the hinge groove 41.

[0043] like Figure 5 As shown, the connecting block 4 has a weight-reducing cavity 43 connected to the hinge groove 41, and the opening of the weight-reducing cavity 43 faces downward. When the lower umbrella plate 22 moves downward relative to the upper umbrella plate 21 to fold the umbrella, the other end of the connecting block 4 abuts against the upper end of the upper umbrella rib 23, and the upper umbrella rib 23 is partially located in the weight-reducing cavity 43.

[0044] like Figure 4 and Figure 5 As shown, hinge holes 1 411 are provided on the groove walls on both sides of the hinge groove 41, and hinge holes 231 are provided on the upper rib 23, which are arranged opposite to the hinge holes 1 411. The umbrella top cloth connection structure also includes hinge screws 6 and nuts 7, and one end of the hinge screws 6 passes through the hinge holes 1 411 and the hinge holes 231 in sequence and is fixedly connected to the nuts 7.

[0045] like Figures 1-4As shown, the other end of the connecting block 4 has a connecting post 44. An installation hole 441 penetrating the top surface of the connecting block 4 is formed in the connecting post 44, and the connecting post 44 is located inside the connecting block 4. The top umbrella cloth 5 is connected to the connecting post 44 through a fastener 8 passing through the installation hole 441. An annular umbrella surface pressing piece 9 is provided between the top umbrella cloth 5 and the fastener 8. The upper end surface of the connecting block 4 is an arc surface.

[0046] As Figures 1-4 shown, there are four connecting blocks 4 and eight upper umbrella ribs 23. The four connecting blocks 4 are respectively hinged to four of the upper umbrella ribs 23.

[0047] The number of the connecting blocks 4 can also be three, five, six, etc.
