Abstract
Description
A folding chair Technical Field
[0001] This utility model relates to a seat, specifically a folding seat that can free up space. Background Technology
[0002] Currently, all seats used in small boats are fixed. When the size of a small boat is small, the space occupied by fixed seats may affect the movement and operation of personnel, restricting the mobility of the crew. Especially when the personnel are densely distributed inside lifeboats and rescue boats, fixed seats can hinder the entry of injured persons or stretchers, affecting the efficiency of rescue and relief efforts. Summary of the Invention
[0003] This invention provides a folding seat, which solves the problem of large space occupation of currently used fixed seats.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A folding seat includes a seat plate and a fixed bracket fixed inside a boat. The bottom of the seat plate is provided with a hinge bracket, one end of which is hinged to one end of the fixed bracket. An inclined support frame is provided between the hinge bracket and the fixed bracket. One end of the inclined support frame is hinged to the hinge bracket via a first pin, and the other end is hinged to the fixed bracket via a second pin. A guide rail is provided on the fixed bracket, and the second pin is disposed in the guide rail. The second pin moves along the guide rail, causing the seat plate to rotate relative to the fixed bracket.
[0006] Furthermore, the fixed bracket is provided with a fixing pin, and a fixing clip is hinged to the second pin shaft; the fixing clip is provided with an arc-shaped groove that matches the fixing pin, and the fixing clip is engaged with the fixing pin to keep the base plate in a horizontal state.
[0007] Furthermore, the fixed bracket is provided with a U-shaped groove, which is adapted to the first pin; when the base plate is in a vertical state, the first pin is engaged in the U-shaped groove.
[0008] Furthermore, the fixed bracket and the hinged bracket are U-shaped channel steel, and the width of the hinged bracket is greater than the width of the fixed bracket.
[0009] Furthermore, the inclined support frame is provided with reinforcing ribs to increase strength.
[0010] Furthermore, the seat plate is square, and all four corners of the seat plate have rounded corners.
[0011] By adopting the above technical solution, the beneficial technical effects of this utility model are:
[0012] This invention changes the seat's state by moving a second pin within a guide rail, allowing the seat to be unfolded when needed and folded away when not in use. When unfolding, the second pin moves upwards within the guide rail, engaging the arc-shaped groove of the fixing clip with the fixing pin, providing support for the seat and facilitating seating. When not in use, the fixing pin is first lifted upwards and placed in the fixing bracket, then the second pin is allowed to fall freely, thus folding the seat back into place. This invention frees up space within the vessel by folding the seat, providing more usable space for occupants. When applied to lifeboats or rescue boats, it facilitates the entry of stretchers or injured personnel, improving rescue efficiency. Attached Figure Description

[0018] As shown in Figures 1 and 2, a folding seat includes a seat plate 1 and a fixed bracket 2 fixed inside the boat. The fixed bracket 2 is bolted to a vertical structure such as a bulwark or bulkhead. A hinged bracket 3 is located at the bottom of the seat plate 1, and its rear end is hinged to the top end of the fixed bracket 2. A diagonal support frame 4 is provided between the hinged bracket 3 and the fixed bracket 2. One end of the diagonal support frame 4 is hinged to the hinged bracket 3 via a first pin 11, and the other end is hinged to the fixed bracket 2 via a second pin 12. A guide rail 13 is provided on the fixed bracket 2, and the second pin 12 is disposed in the guide rail 13. Moving the second pin 12 along the guide rail 13 causes the seat plate 1 to rotate relative to the fixed bracket 2. When the second pin 12 moves upward along the guide rail 13, the seat plate 1 eventually reaches a horizontal position, allowing passengers to sit. When the second pin 12 moves downward along the guide rail 13, the seat plate 1 eventually reaches a vertical position, freeing up space inside the small boat. The hinged bracket has rounded corners to prevent the endpoints from interfering with the fixed bulkhead or wall when the seat plate 1 rotates.
[0019] As shown in Figures 3 to 5, the fixed bracket 2 is provided with a fixing pin 14, and a fixing clip 15 is hinged to the second pin shaft 12. The fixing clip 15 is provided with an arc-shaped groove 16 that matches the fixing pin 14. The fixing clip 15 is engaged with the fixing pin 14, so that the seat plate 1 is in a horizontal state. The second pin shaft 12 moves upward along the guide rail 13 until the fixing clip 15 can be engaged with the fixing pin 14, and the seat plate 1 will be in a horizontal state. The fixing pin 14 provides support for the seat plate 1 for the passenger to sit on. When the seat plate 1 is idle, the fixing clip 15 is first lifted upward, so that the arc-shaped groove 16 of the fixing clip 15 is disengaged from the fixing pin 14. Then, the second pin shaft 12 is moved upward a certain distance until the fixing clip 15 can be rotated and completely placed in the fixed bracket 2. Then, the second pin shaft 12 is allowed to fall freely along the guide rail 13, and the seat is finally in a vertical state, freeing up space inside the small boat.
[0020] The fixed bracket 2 is provided with a U-shaped groove 17, which is adapted to the first pin 11. When the base plate 1 is in a vertical state, the first pin 11 is engaged in the U-shaped groove 17. A third pin is provided at the hinge point between the hinge bracket 3 and the fixed bracket 2. The distance between the first pin 11 and the third pin should be equal to the distance between the third pin and the U-shaped groove 17, so that the first pin 11 can be engaged in the U-shaped groove 17.
[0021] The fixed bracket 2 and the hinge bracket 3 are U-shaped channel steel. The width of the hinge bracket 3 is greater than the width of the fixed bracket 2. When the seat plate 1 is stored, the hinge bracket 3 will fit over the outside of the fixed bracket 2 to ensure that the seat plate 1 is in a vertical position, thus maximizing the release of space inside the small boat.
[0022] The inclined support frame 4 is equipped with reinforcing ribs 18 to increase strength, thereby extending the service life of the seat. The seat plate 1 is square, and all four corners of the seat plate 1 are rounded to prevent sharp corners from causing unnecessary injury to passengers.
[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
