Description

Technical Field

[0001] This utility model belongs to the technical field of sunshades for outdoor folding chairs and beds, and specifically relates to a folding chair sunshade connector and sunshade frame. Background Technology

[0002] Outdoor leisure products are based on stools and chairs, and also include tables and beds, all of which are foldable to reduce space occupation during transportation and storage. In particular, chairs and beds need to be equipped with awnings to provide independent sun and rain protection. These awnings also need to be foldable. Currently, awnings are designed to be matched with folding chairs or beds. For example: CN201320182376.X discloses a canopy frame for a folding chair, featuring folding supports on both sides. Each support includes a support rod hinged to the upper end of the chair backrest and a crossbar for opening a flexible canopy. A connector is fixed to the upper end of the support rod, with a circular groove at its top. The crossbar is hinged to the connector via rivets, and the opened crossbar partially rests in the circular groove for support. A folding assembly connects the two crossbars. This design requires a fixed base to be locked to the upper end of the chair backrest for hinged support. The canopy frame is an integrated structure with the folding chair, allowing it to be folded and folded away from the backrest when not in use, saving space.

[0003] CN202123091061.8 discloses a damping positioning device and a sunshade, which optimizes the awning frame to achieve detachable and foldable functions. The disclosed sunshade includes a support frame and a canopy symmetrically arranged on both sides. The support frame includes a vertical rod, a horizontal rod, a diagonal rod, and a damping positioning device. The damping positioning device includes a fixing component and a damping component. The lower end of the vertical rod is locked to the fixing component, and the upper end is rotatably hinged to the horizontal rod. The diagonal rod passes through an arc-shaped groove or arc-shaped hole of the damping component, and the upper end is rotatably hinged to the horizontal rod. By sliding the diagonal rod relative to the damping component, the pitch angle and folding structure of the horizontal rod can be adjusted. The canopy is fitted onto the two horizontal rods on both sides, and the fixing component is detachably inserted and locked into a mortise at the end of the backrest rod via a connected tenon. During use, the mortise must first be locked onto the backrest rod, and the mortise must be paired with the backrest rod.

[0004] Both of these require the design of a fixed seat or mortise that corresponds one-to-one with the backrest rod to secure it to the backrest rod for bridging the canopy, making installation difficult and preventing the arbitrary selection of canopies. Therefore, providing a more reasonable technical solution is the subject of this invention. Summary of the Invention

[0005] The purpose of this invention is to design a folding chair canopy connector that can be directly inserted into the top of the backrest rod, and a canopy frame including the connector.

[0006] The present invention is implemented as follows: a folding chair canopy insert base, characterized in that: the insert base is a conical structure with an open section and a conical top section, and a long groove is formed on one side for the backrest material to be cut into, the long groove extending from the opening of the open section to the conical top section; the outer wall of the insert base is also provided with a connecting part for fixing the canopy frame.

[0007] The cone-shaped apex of the connector is an oblique cone-shaped apex, and the opening section and the cone-shaped apex section share a flat side surface; the flat side surface is tangent to the circular opening section and forms an outwardly convex rounded corner, which is radially corresponding to the long groove.

[0008] The connecting part is formed on a flat side or a conical apex section where a flat side intersects with a circular arc, and the angle between the center line of the connecting part and the center line of the opening section is between 3 and 7 degrees.

[0009] The cone-shaped section occupies between one-third and one-half of the total length of the connector.

[0010] A canopy frame includes the aforementioned folding chair canopy insert base, and a canopy frame having connections to two backrest rods, characterized in that: two fixed seats of the canopy frame are respectively locked or formed on the connecting part of the insert base, forming an integral unit.

[0011] Furthermore, the canopy frame has symmetrical supports on both sides. Each support includes a vertical rod, a horizontal rod, an oblique rod, and a damping positioning mechanism. The damping positioning mechanism includes a fixed base and a damping element that is rotatably riveted to the fixed base. An arc-shaped groove for the oblique rod to pass through is provided on the plane where the damping element is riveted to the fixed base. The lower end of the vertical rod is locked to the fixed base, and the upper end is rotatably hinged to the horizontal rod. The upper end of the oblique rod is rotatably hinged to the horizontal rod, and the lower end passes through the arc-shaped groove of the damping element, forming a triangular support structure, and the arc-shaped groove forms a damping self-positioning. The sliding of the oblique rod relative to the damping element can adjust the pitch angle of the horizontal rod, as well as its unfolding and folding. The two horizontal rods are used to open the canopy.

[0012] Furthermore, the fixed base has a groove formed in the middle, and the damping member can be rotatably embedded in the groove. The arc-shaped groove is closed by the groove wall, which can constrain the oblique rod in it.

[0013] This utility model adopts a cone-shaped plug-in seat to be compatible with backrest rods of different diameters, all of which can be inserted and obtain stable support with the help of the cone apex; while the long groove can not only allow the backrest material to cut in, but also constrain the direction of the plug-in seat with the backrest material; it can be used on any folding chair with backrest material supported by two backrest rods to solve the problem of quick assembly and disassembly of the canopy frame; the canopy frame with plug-in seat has the characteristics of simple structure, good compatibility and quick assembly and disassembly.

[0015] Reference Figures 1 to 4 The folding chair canopy connector 1 has a conical structure with an opening section 11 and a cone top section 12, and a long groove 13 is formed on one side to allow the backrest material to cut into when the upper end of the backrest rod is inserted; the long groove 13 extends from the opening of the opening section 11 to the cone top section 12, thus avoiding obstruction by the backrest material and affecting the firmness of the connector 1; a connecting part 14 is also provided on the outer wall of the connector 1, which is used to fix the canopy frame.

[0016] Furthermore, the conical apex section 12 of the connector is an oblique conical apex, and the opening section 11 and the conical apex section 12 share a flat side surface 15. This flat side surface 15 is tangent to the circular opening section 11 and forms an outwardly convex rounded corner 16, which is radially corresponding to the elongated groove 13. Due to the design of the flat side surface 15, the edge strength of the connector 1 cannot be affected. Therefore, the flat side surface 15 is designed by cutting a plane, which also forms an outwardly convex rounded corner 16. The existence of this outwardly convex rounded corner 16 provides space for the excess fabric on the backrest rod surface during use. In addition, some backrest fabrics are sewn to form a sleeve that can fit into the backrest rod. This outwardly convex rounded corner 16 can just accommodate this sewn edge, and the backrest fabric part can cut into the radially corresponding elongated groove 13, forming an unexpected effect and also enhancing the anti-rotation capability.

[0017] like Figure 3 and Figure 4 The connecting portion 14 is formed on the flat side 15 or the conical apex section where the flat side 15 intersects with the arc, and the angle X between the center line of the connecting portion 14 and the center line of the opening section 11 is between 3 and 7 degrees, or the angle X between the insertion direction of the connecting portion 14 and the insertion direction of the opening section 11 is between 3 and 7 degrees. The small angle between the connecting portion 14 and the opening section 11 causes the supported side supports to tilt slightly outward, exhibiting an outward tendency, in order to tighten the canopy fabric.

[0018] The conical apex section 12 adopts a sloping conical apex design. After the backrest rod is inserted, the conical apex is compatible with pipes of different diameters. The sloping conical apex also drives the backrest rod to contact the flat side 15, and the larger contact area maintains the stability of the connector 1. Furthermore, the sloping conical apex also facilitates the staggered placement of the two connectors 1 when stored, reducing space occupation. The conical apex section 12 occupies between one-third and one-half of the total length of the connector, maintaining stability even when inserted into the largest designed backrest rod. The connector 1 is used for convenient and detachable connection between the folding chair backrest rod and the canopy frame. It is integrated with the canopy frame for convenient use and storage. Details are as follows: Reference Figure 5 and Figure 6 The diagram shows two folding chairs with different functions. Both have two backrest bars 2 on the rear facade. The two fixing seats 61 on the canopy frame are respectively locked to the connecting part 14 of the plug-in seat 1, or are integrally formed with the plug-in seat 1 to form a whole for easy disassembly and assembly. The former is suitable for compatibility modification of existing canopy frames, while the latter is suitable for newly designed products.

[0019] The canopy frame has symmetrical supports on both sides. Each support includes a vertical rod 3, a horizontal rod 4, an oblique rod 5, and a damping positioning mechanism 6. The damping positioning mechanism 6 includes a fixed base 61 and a damping element 62. The damping element 62 is rotatably riveted to the fixed base 61. An arc-shaped groove 621 for the oblique rod 5 to pass through is provided on the plane where the damping element 62 is riveted to the fixed base 61. The lower end of the vertical rod 3 is locked to the fixed base 61, and the upper end is rotatably hinged to the horizontal rod 4. The upper end of the oblique rod 5 is rotatably hinged to the horizontal rod 4, and the lower end passes through the arc-shaped groove 621 of the damping element, forming a triangular support structure. The arc-shaped groove 621 forms a damping self-positioning. The sliding of the oblique rod 5 relative to the damping element 62 can adjust the pitch angle of the horizontal rod 4, as well as its unfolding and folding. The two horizontal rods 4 are used to open the canopy. In this example, the vertical rod 3, the horizontal rod 4, and the diagonal rod 5 are all made of carbon fiber, which is both lightweight and deformable. They can generate greater resistance when passing through the arc groove 621 to meet the support requirements. In addition, they are positioned on the backrest rod 2 through the plug-in seat 1. The two horizontal rods 4 are slightly deflected outwards, using deformation force to tighten the flexible canopy fabric.

[0020] Furthermore, the fixed base 61 has a groove 611 formed in the middle, and the damping member 62 is rotatably embedded in the groove 611. The arc-shaped groove 621 is closed by means of one groove wall of the groove, which can constrain the oblique rod 5 in it, making the overall integrity stronger.

[0021] In summary, this design can be used to achieve quick assembly and disassembly of awnings for any folding scheme that uses two backrest rods to support the backrest material, and it is compatible with different specifications of backrest rod diameters, thus improving the versatility of awnings.
