Description

Umbrella joint structure

The present invention relates to a rib joint structure, and more particularly to a joint structure for a joint between a rib and a bone.

According to the various large outdoor umbrellas used in beaches or markets, there is usually a canopy that can form a large shielding area, but the ribs, bones and joints used to support the umbrella surface are similar to ordinary umbrellas.

In the general large umbrella structure shown in Figures 1 and 2, in a particular length, the rod 1 is provided with an upper nest 11 near the top end and an umbrella nest 12 below it. The rib group for forming the supporting umbrella surface comprises a joint 15 disposed in the middle of the whole rib 13 and between the joint 15 of each rib 13 and the lower shed 12 respectively. To support the umbrella surface, the entire large umbrella is usually controlled by a drawstring 17 to pull or close.

The joint mechanism of the conventional large umbrella mainly connects the rib 13 and the bone 16 with a T-shaped joint 15 , and the rivet 14 is pivotally connected to one end of the shank 16 , as shown in the second figure, in the rib 13 combination After the joint 15, the ribs 13 are punched out of the locking portion 18 to be slightly engaged with the positioning opening 19 of the joint 15. However, the positioning structure of the joint 15 is not ideal, and under long-term use, the joint 15 and the rib 13 are prone to loose displacement, thereby reducing the strength of the stressed structure and affecting the opening and closing operations. Therefore, how to solve the above-mentioned shortcomings and shortcomings of the prior art is the subject of improvement for those involved in this industry. Where.

The main purpose and function of the creation is that the joint is inserted into the inner surface of the opposite top wall of the rib with the tip end of the insertion portion facing downward, so that the combination is firmly fixed, avoids loose displacement, is more durable, and is convenient to manufacture and assemble. To improve production efficiency.

In order to achieve the goal, the present invention is provided with a joint in the middle of the rib to be used for pivoting the opposite end of the rib; the joint is set as a metal sheet punching body, which comprises a top sheet, and A clamping piece is extended on each side of the top piece to be folded downward to be sandwiched on two opposite sides of the rib, and the two sides of the clamping piece protrude downwardly from each other to extend a pivoting ear including a pivot hole, and a pivoting piece The two pivot holes are pivoted to the opposite ends of the bone; the top piece of the joint is provided with a downwardly extending insertion portion for positioning downwardly into the interior of the opposite top wall surface of the rib.

In a preferred embodiment, a through hole is formed in the top sheet of the joint, and the top sheet extends downwardly from the side of the through hole to the insertion portion.

Further, the insert portion of the top sheet has a bottom tip. Further, the insert portion of the top sheet penetrates the thickness of the apex top wall surface downward.

In a preferred embodiment, the two sides of the joint are respectively folded inwardly with a bottom clip to be placed on the opposite bottom wall surface of the rib.

For the purpose of achieving the above objectives, the technical means and its efficacy, the following examples are given, and the following diagrams are explained: First, please refer to the third and fourth figures. This creation is mainly applicable to umbrellas of large umbrellas. bone 2, the joint structure of the joint 3 and the bone 4, as shown in the figure, the large umbrella in the middle of each rib 2 is respectively placed and fixed a joint 3 for pivoting the opposite end of the bone 4, and as Open the umbrella and the joint mechanism of the umbrella.

In the preferred embodiment shown in the third to eighth figures, the inventive joint 3 is mainly provided as a sheet metal punching body 31, which comprises a top sheet 32, and the top side of the top sheet 32 is oppositely facing each other. The folding piece 33 is extended to sandwich the opposite sides of the rib 2, and the clamping pieces 33 on the two sides respectively protrude downwardly from a pivoting ear 35 having a pivot hole 37, and a pivoting member The nails 5 extend through the two pivot holes 37 to pivot the opposite ends of the bones 4.

The creation joint 3 is mainly provided with a downwardly extending insertion portion 36 on the top sheet 32 for positioning downwardly into the opposite top wall surface 21 of the rib 2, and the side sheets 33 of the joint 3 are opposite to each other. A bottom clip 34 is folded inwardly to sandwich the opposite bottom wall surface 22 of the rib 2, and at the same time, the locking portion 24 is punched out at the rib 2 to be engaged with the positioning opening 38 to assist the fixing.

Continuing with the description of the combined structure of the rib 2 and the joint 3 of the present invention, as shown in the third to eighth figures, the sandwiching sheets 33 on both sides of the joint 3 are initially set to be open, and a punch is formed on the top sheet 32 of the joint 3. The hole 321 extends the top sheet 32 downwardly from the side of the through hole 321 to the insertion portion 36, and the insertion portion 36 of the top sheet 32 has a bottom end 361, so that the insertion portion 36 of the top sheet 32 is The bottom tip 361 is stamped downwardly through the thickness of the top wall surface 21 of the rib 2 and is formed with the positioning of the snap hole 23.

When the rib 2 is assembled with the joint 3, as shown in the fifth to eighth figures, the open joint 3 is placed on the rib 2, and then punched by the die and the fixture to make the joint The top piece 32 of the top, the side clamping piece 33 and the bottom side piece 34 sandwich the rib 2, and the insertion portion 36 is formed with the bottom end 361 facing downward through the thickness of the top wall surface 21 of the rib 2 to form a card. The holes 23 are positioned to achieve a firm and secure combination, avoid loose displacement, are more durable, and are easy to manufacture and assemble to improve production efficiency.

The above embodiments are only used to facilitate the description of the present invention, and are not intended to be limiting, and all kinds of simple changes and modifications that can be made by those skilled in the art without departing from the spirit of the present invention should still be included in the following patent applications.
