Rattan chair back connector, connection assembly, and rattan chair

Abstract

A connector comprises a body, a first connection part, and a second connection part. The first connection part and the second connection part are respectively disposed at two adjacent side surfaces of the body of the connector. The first connection part and a horizontal rod are engaged, the second connection part and a vertical rod are engaged, to form a detachable connection between the horizontal rod and the vertical rod with the connector. Without dealing with an over edging operation of a boundary and a corner of the frame, the rattan pieces are directly connected to the horizontal rod or the vertical rod, to perform the weaving of the chair back, which greatly reduces the difficulty of weaving. The first side surface is a step shaped surface, which reduces the difficulty of the engaged connection between the first connection part and the horizontal rod. The connector is a one-piece structure.

DETAILED DESCRIPTION OF THE INVENTION

(15) The present invention will be described in detail below with reference to the accompanying drawings.

(16) Please refer to FIG. 1, this invention provides a rattan chair, including a rattan chair back connection assembly 1, a chair back 2, and a support frame 3.

(17) Please refer to FIG. 4, the rattan chair back connection assembly 1 includes a frame 11, a connector 12 and a fixer 13. The chair back 2 includes rattan pieces 21 and a lock bar 22, and the rattan pieces 21 are woven from rattan. The lock bar 22 is disposed at a surrounding of the rattan pieces 21, for an engaged connection between the frame 11 and the connector 12.

(18) The frame 11 includes a horizontal rod 111 and a vertical rod 112, and the horizontal rod 111 and the vertical rod 112 are detachably connected by the connector 12 and the fixer 13. The connector 12 includes a body 121, a first connection part 122, a second connection part 123 and a third connection part 124.

(19) Please refer to FIG. 2-3, the body 121 has a first side surface 1211 and a second side surface 1212 which are adjacent. The first connection part 122 is disposed at the first side surface 1211, and the second connection part 123 is disposed at the second side surface 1212. The first side surface 1211 in a step shape includes a first step surface 1213 and a second step surface 1214. The second step surface 1214 is higher than the first step surface 1213.

(20) The first connection part 122 and the second connection part 123 are respectively disposed at two adjacent side surfaces of the body 121 of the connector 12. Please refer to FIGS. 4, 5, 11, and 12, the first connection part 122 and the horizontal rod 111 are engaged, the second connection part 123 and the vertical rod 112 are engaged, to form a detachable connection between the horizontal rod 111 and the vertical rod 112 with the connector 12. Without dealing with an over edging operation of a boundary and a corner of the frame 11, the rattan pieces 21 are directly connected to the horizontal rod 111 or the vertical rod 112, to perform the weaving of the chair back 2, which greatly reduces the difficulty of weaving. The first side surface 1211 is a step shaped surface, which reduces the difficulty of the engaged connection between the first connection part 122 and the horizontal rod 111. The connector 12 is in a one-piece structure, so there is no need to do the assembly and flipping, which reduces the difficulty of assembly, saves labor costs and time costs, and also improves the overall aesthetics of the rattan chair.

(21) The third connection part 124 which is in a plate like shape is disposed at the second step surface 1214, and a free end of the third connection part 124 is in an arc shape.

(22) A first connection hole 1241 is disposed at the third connection part 124, and a second connection hole 1111 is disposed at an end of the horizontal rod 111. The first connection hole 1241 and the second connection hole 1111 are cooperated with the fixer 13 to form a fix connection. Thus, the third connection part 124 is fixedly connected to the horizontal rod 111. In this embodiment, the fixer 13 is a screw, and the second connection hole 1111 is a threaded hole.

(23) The body 121 further has a third side surface 1216 opposite the first side surface 1211. The body 121 has a first rattan slot 1215, for an insert of the lock bar 22 of an end of the rattan pieces 21. Specially, a slot mouth of the first rattan slot 1215 turn towards the third side surface 1216 of the body 121. An opening gap of the slot mouth of the first rattan slot 1215 is smaller than a width of a slot body, so the lock bar 22 can only be inserted from an end of the slot mouth into the first rattan slot 1215 and move along a length direction of the first rattan slot 1215, but cannot be threaded out of the slot mouth, thereby limiting the position of the rattan pieces 21.

(24) After inserting the rattan pieces 21 into the first rattan slot 1215, the lock bar 22 is limited inside the slot, and the rattan pieces 21 are threaded out of the slot mouth. Please refer to FIG. 6-10, a second rattan slot 1112 and a third rattan slot 1121 are respectively disposed at any one of the horizontal rod 111 and the vertical rod 112. The second rattan slot 1112 and the third rattan slot 1121 are respectively disposed along a length direction of the horizontal rod 111 and the vertical rod 112, for an inserting of the lock bar 22.

(25) An opening gap of the second rattan slot 1112 and the third rattan slot 1121 is smaller than a width of a slot body, preventing the lock bar 22 from slipping out of a gap of the slot mouth, and the slot mouth is used for a passage of a rattan. A function of the second rattan slot 1112 and the third rattan slot 1121 is same as a function of the first rattan slot 1215.

(26) Specially, the horizontal rod 111 and the vertical rod 112 both are internal hollow, and thin-walled tube shaped. The second rattan slot 1112 is formed by an inwardly depression of one of the sides of the horizontal rod 111, to form a first through slot 1113 inside the horizontal rod 111. A shape of the first connection part 122 of the connector 12 is match with a shape of the first through slot 1113.

(27) A structure of the third rattan slot 1121 is same with a structure of the second rattan slot 1112. The third rattan slot 1121 is disposed at the vertical rod 112, forming a second through slot 1122 inside the vertical rod 112. A structure of the second connection part 123 of the connector 12 is match with a shape of the second through slot 1122.

(28) When the horizontal rod 111 is connected to the vertical rod 112 with the connector 12, the first connection part 122 is inserted into the first through slot 1113 of the horizontal rod 111, and the second connection part 123 is inserted into the second through slot 1122 of the vertical rod 112.

(29) The vertical rod 112 includes a seat section 1123 and a backrest section 1124. A connection between the seat section 1123 and the backrest section 1124 is a one-piece arc-shaped connection, and an angle between the seat section 1123 and the backrest section 1124 is larger than 90°. The rattan pieces 21 connected to the seat section 1123 form a seat, and the rattan pieces 21 connected to the backrest section 1124 form backrest. The connection between the seat section 1123 and the backrest section 1124 is in an arc shape, making the rattan pieces 21 transit smoothly at this connection, to reduce a damage rate of the rattan pieces 21. The angle between of the seat section 1123 and the backrest section 1124 is more than 90°, making the chair back 2 more ergonomic and more comfortable.

(30) The support frame 3 include two support feet 31 and two support rods 32. Two support rods 32 both are disposed between two support feet 31, and are fixedly connected to the support feet 31. The frame 11 are fixedly connected to two support rods 32.

(31) Each of the support feet 31 is in a “∩” shape. A top end of each of the support feet 31 form an armrest 311, and two free ends are slightly inclined outward to form a foot 312. Such structure of the support foot 31 is more stable, and the support foot 31 are beautiful in appearance.

(32) The above mentioned is only a preferred embodiment of the present invention, and thus does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the specification and the contents of the drawings of the present invention is directly or indirectly applied to other related, and the technical field is equally included in the scope of protection of the present invention.
