Those skilled in the art can easily appreciate other advantages and effects of the utility model by referring to the contents in the specification.

(14) To simplify the description and illustration, connectors, such as bolts or rivets, are not shown in the drawings of this embodiment, and the connectors are merely illustrated by bolts or rivets in the verbal description.

(15) As shown in the figures, this embodiment discloses a dual-use bleacher seat which comprises a backrest 1, a cushion assembly 2, two L-shaped hooks 4 and two U-shaped leg tubes 6, wherein the backrest 1 is rotatably connected to the cushion assembly 2, the two L-shaped hooks 4 are rotatably connected to the left and right sides of the front end of the bottom surface of the cushion assembly 2 respectively, and the two U-shaped leg tubes 6 are rotatably connected to the left and right sides of the bottom surface of the cushion assembly 2 respectively. Wherein, the backrest 1, the L-shaped hooks 4 and the U-shaped leg tubes 6 can be folded to be stored to allow the dual-use bleacher seat to be carried conveniently and to be stored in a small space.

(16) Specifically, the cushion assembly 2 comprises a seat cloth 9 and a rectangular cushion frame 8, wherein the left and right sides of the seat cloth 9 are fixedly mounted on the left and right sides of the cushion frame 8, and a concave cavity is formed between the lower surface of the seat cloth 9 and the cushion frame 8. When rotated to be folded on the cushion assembly 2, the U-shaped leg tubes 6 are received in the concave cavity, the L-shaped hooks 4 are rotatably connected to the bottom surface of the cushion assembly 2, and the L-shaped hooks 4 and the U-shaped leg tubes 6 are folded in a staggered manner to be received in the concave cavity.

(17) When the dual-use bleacher seat is unfolded to serve as a bleacher seat (as shown in FIG. 1a and FIG. 1b), the U-shaped leg tubes 6 are folded to be hidden in the concave cavity of the cushion assembly 2, and the L-shaped hooks 4 can be hooked on a bleacher. When the dual-use bleacher seat is unfolded to serve as a leisure chair (as shown in FIG. 2a and FIG. 2b), the L-shaped hooks 4 are folded to be hidden in the concave cavity of the cushion assembly 2, and the U-shaped leg tubes 6 are unfolded to support the seat. When the dual-use bleacher seat is in a folded and stored state (as shown in FIG. 3a and FIG. 3b), the L-shaped hooks 4 and the U-shaped leg tubes 6 are folded in a staggered manner to be hidden in the concave cavity of the cushion assembly 2, and at this moment, the backrest 1 is folded towards the cushion assembly 2.

(18) Principal structural combination and assembly of the dual-use bleacher seat in this embodiment are shown in the exploded view (FIG. 4). The dual-use bleacher seat is mainly composed of a backrest 1, four metal connecting pieces 5, a cushion assembly 2, four U-shaped elastic connectors 3 (preferably made of plastic), four U-shaped metal sheets 10, two U-shaped leg tubes 6, two elastic pieces with round pins 11 (U-shaped elastic pieces are preferred, and the round pins are disposed on one side of the elastic pieces), and two L-shaped hooks 4, wherein the cushion assembly 2 is composed of a cushion frame 8 and a seat cloth 9.

(19) The backrest 1 is rotatably connected to the metal connecting pieces 5 in a riveted manner through two vertical tubes on the left and right sides, the other end of each metal connecting piece 5 is fixedly connected to the cushion frame 8 in a riveted manner, and the seat cloth 9 is mounted and fixed on the upper side of the cushion frame 8, so that a concave cavity will be formed between the cushion assembly 2 and the ground in the working condition.

(20) The four U-shaped elastic connectors 3 are fixedly mounted at four corners of the bottom surface of the cushion frame 8 respectively, and the four U-shaped metal sheets 10 are wrapped and mounted in inner cavities of the four U-shaped elastic connectors 3. The two L-shaped hooks 4 are mounted on the two U-shaped elastic connectors 3 at the two ends of a cross rod, on the front side of the seat, of the cushion frame 8 through bolts and nuts respectively and are located on one side of the concave cavity of the cushion assembly 2 (as shown in FIG. 1a, FIG. 1b, FIG. 2a and FIG. 2b). The left and right sides of the two U-shaped leg tubes 6 are mounted in the inner cavities of the four U-shaped elastic connectors 3 respectively, the two elastic pieces with round pins 11 are hidden and mounted in open ends of outer tubes of the U-shaped elastic connectors 3 respectively (as shown in FIG. 4), and the round pin of each elastic piece with the round pin 11 is clamped in a through hole of one U-shaped elastic connector 3 and is opposite to a press protruding point 14 on the U-shaped elastic connector 3. Four L-shaped elastic leg pads (made of plastic) are fixedly mounted on the sides, towards the ground, of U-shaped bent parts of the two U-shaped leg tubes 6 respectively.

(21) Referring to FIG. 6a and FIG. 6b, each U-shaped elastic connector 3 is a U-shaped plastic structural member, wherein a press mark 15 is designed on an exposed side of the U-shaped elastic connector 3, one press protruding point 14 is designed on the side, towards a U-shaped cavity, of the U-shaped elastic connector 3 and corresponds to the press mark 15, an oblique concave face 12 is designed in the U-shaped cavity of the U-shaped elastic connector 3 and is matched with one U-shaped leg tube 6 in an unfolded state, two clamping protrusions 13 which are bilaterally symmetrical to each other are designed at the positions, where the U-shaped leg tubes 6 are fixed and supported in the unfolded state, of the oblique concave face 12, and the oblique concave face 12 and the clamping protrusions 13 are used to support the U-shaped leg tube 6 in the unfolded state.

(22) As shown in FIG. 1a and FIG. 1b, when the dual-use bleacher seat in this embodiment is unfolded to serve as a bleacher seat, the U-shaped leg tubes 6 are folded to be hidden in the concave cavity of the cushion assembly 2, at this moment, the L-shaped hooks are rotated and opened to be perpendicular to the seat cloth 9 and are then locked with nuts, and finally, the L-shaped hooks are hooked on a bleacher.

(23) As shown in FIG. 2a, FIG. 2b, FIG. 5a and FIG. 5b, when the dual-use bleacher seat in this embodiment is unfolded to serve as a leisure chair, the U-shaped leg tubes 6 are unfolded, at this moment, the U-shaped leg tubes 6 and the elastic pieces with the round pins 11 lean against the oblique concave faces 12 of the U-shaped elastic connectors 3, and the round pins of the elastic pieces 11 stretch out of the outer ends of the U-shaped leg tubes 6 to be clamped in the through holes of the U-shaped metal sheets 10 and are exactly aligned to the press protruding points 13 on the U-shaped elastic connectors 3 in position; in this state, the round pins of the elastic pieces 11 are clamped in the through holes of the U-shaped metal sheets 10 to fulfill fixation, and the outer round tube walls of the U-shaped leg tubes 6 are supported and fixed by the clamping protrusions 13 on the U-shaped elastic connectors 3 at this moment. When the U-shaped leg tubes 6 need to be folded to be stored, a user can press the press marks 15 on the U-shaped elastic connectors 3 by hand to push the elastic press protruding points 14 towards the round pins of the elastic pieces 11 to enable the round pins of the elastic pieces to disengage from the through holes of the U-shaped metal sheets 10, and then, the U-shaped leg tubes are rotated by a certain angle to be finally received in the concave cavity of the cushion assembly 2.

(24) As shown in FIG. 3a and FIG. 3b, when the dual-use bleacher seat in this embodiment is folded to be stored state, the L-shaped hooks 4 and the U-shaped leg tubes are mechanically rotated and pressed with reference to the above-mentioned unfolding steps so as to be completely hidden in the concave cavity of the cushion assembly 2, and at this moment, the backrest assembly 1 of the seat is rotated and folded towards the cushion assembly 2, so that the dual-use bleacher seat is folded and stored.

(25) The aforementioned embodiments are merely preferred ones of the utility model, and are not intended to limit the protection scope of the utility mode, and all transformations and improvements made by those skilled in the art according to the design concept of the utility model should fall within the protection scope of the utility model.
