Cot

Abstract

To provide a cot which allows a seat to be easily removed from a frame and which achieves both convenience and safety by preventing the attached seat from coming off unexpectedly. [Solution] The cot (10) is constructed by joining a flexible sheet (18) to rigid frames (14, 16), and the joints between the sheet (18) and the frames (14, 16) are made up of two types of joining pieces formed on the sheet (18). The first joining piece is joined to the frames (14, 16) by a wire fastener, and the second joining piece is joined to the frames (14, 16) by a hook-and-loop fastener.

Description

[Technical Field]

[0001] The present invention relates to a cot primarily used in outdoor activities. [Background technology]

[0002] A cot is a folding, simple bed primarily used outdoors, consisting of an outer frame, a seat that is flatly attached to the inside of the frame, and legs that support the two. The frame is made from metal pipes that have been bent into the shape of a bed. The seat is attached to the inside of the frame by sewing it around the perimeter of the pipes.

[0003] [Patent Document 1] Utility Model Registration No. 3221643 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] Cots are often used in environments where they are exposed to wind and rain, spilled with food or drinks, and are prone to getting dirty. In conventional cots, the seat is sewn to the frame, so even if the seat gets dirty, you can only wipe the surface, and it is not possible to remove it from the frame to wash or clean it.

[0005] Therefore, the present invention provides a cot that combines convenience and safety by allowing the seat to be easily removed from the frame and preventing the attached seat from coming off unexpectedly. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention comprises the following means.

[0007] A cot constructed by joining a flexible sheet to a rigid frame, The joint between the sheet and the frame is formed by a joint piece formed on the sheet, The joining piece is joined to the frame by at least one of a wire fastener and a hook-and-loop fastener.

[0008] Conventionally, the seat was completely fixed to the frame by sewing, but by using fixing means such as wire fasteners or hook-and-loop fasteners, the seat can be detached from the frame.

[0009] The joining pieces are characterized in that the first joining piece is a first joining piece that is joined to the frame by a line fastener, and the second joining piece is a second joining piece that is joined to the frame by a hook-and-loop fastener.

[0010] By using two types of joining pieces, a first joining piece and a second joining piece, to join the seat to the frame, even if one piece suddenly comes off, the other will support the seat, ensuring the safety of the user.

[0011] The first joint piece is directly joined to the frame, and the second joint piece is joined to the frame from outside the first joint piece.

[0012] The first connecting piece is closed with a wire fastener to form a cylindrical shape, preventing accidents such as the sheet accidentally coming off the frame. The second connecting piece can be tensioned by pulling the sheet firmly, which is fixed to the frame by the first connecting piece.

[0013] The male side of the hook-and-loop fastener is provided on the front side of the first joining piece, and the female side of the hook-and-loop fastener is provided on the back side of the second joining piece.

[0014] The hook-and-loop fastener can be attached by simply pulling the second joining piece to apply tension to the sheet and then placing it over the first joining piece. [Effects of the Invention]

[0015] According to this invention, the seat can be removed from the frame and washed or cleaned, making it possible to keep the seat clean, even though it is prone to getting dirty during outdoor activities. [Brief explanation of the drawings]

[0017] [Cot structure] As shown in Figure 1, the cot 10 is composed of a pair of left and right frames 14, 16 formed by combining multiple pipes 12, a seat 18 joined to the inside of the frames 14, 16, and a stand 20 supporting the frames 14, 16. The pipes 12 are rotatably connected via joints 22 provided at several locations.

[0018] The sheet 18 is made of a rectangular cloth material with short and long sides. A pair of left and right joining pieces 24, 26 is provided on the back side of the sheet 18 along the long side. The joining pieces 24, 26 are members for joining the sheet 18 to the frames 14, 16. The joining pieces 24, 26 are made of the same material as the sheet 18, and a bag-shaped joining piece 24 is provided at each end of the long side, with multiple cylindrical joining pieces 26 provided at appropriate intervals between them.

[0019] As shown in Figure 2, the connecting piece 26 is composed of two types of connecting pieces 26a and 26b. The connecting piece 26a is directly connected to the pipe 12, and the connecting piece 26b is connected to the pipe 12 from the outside of the connecting piece 26a. The connecting piece 26a is provided with a wire fastener 28. A hook-and-loop fastener (female) 30a is provided on the back side of the connecting piece 26b, and a mating hook-and-loop fastener (male) 30b is provided on the front side of the connecting piece 26a.

[0020] Joint piece 26a sandwiches pipe 12 from both sides and closes with wire fasteners 28 to form a tube, thereby joining joint piece 26a to pipe 12. When joint piece 26b is placed over joint piece 26a while pulling strongly to apply tension to sheet 18, hook-and-loop fasteners 30a and 30b act to bring joint piece 26b into close contact with joint piece 26a. As a result, joint piece 26b joins pipe 12 from the outside of first joint piece 26a.

[0021] The reason why the sheet 18 is joined to the frames 14, 16 in this manner by using two types of joining pieces 26a, 26b to double-cover the pipe 12 is as follows.

[0022] Simply opening and closing the line fasteners 28 does not provide sufficient tension to the seat 18, causing it to sink and not be able to support the body weight when the cot 10 is in use. On the other hand, the hook-and-loop fasteners 30 can be pulled to create a tight fit, making it possible to provide tension to the seat 18, but because they are not completely fixed like the line fasteners, there is a risk that they may come off unexpectedly. Therefore, by combining the line fasteners 28 and the hook-and-loop fasteners 30, sufficient tension is provided to the seat 18, and even if the hook-and-loop fasteners 30 come off, the line fasteners 28 will maintain the connection between the seat 18 and the frames 14, 16.

[0023] [How to attach and remove the seat] The following describes how to remove and attach the seat 18 to the cot 10. First, the procedure for removing the seat 18 is as follows. (1) When removing the seat 18 from the cot 10 in the expanded state, the joining pieces 26a, 26b are first separated from the frames 14, 16, and then the joining piece 24 is separated from the frames 14, 16. (2) Pull the joining piece 26b to peel off the hook-and-loop fasteners 30a and 30b, thereby exposing the joining piece 26a. (3) Open the wire fastener 28 to expose the pipe 12. (4) The same procedure is carried out for the remaining joining pieces 26a and 26b. (5) Bend the frames 14 and 16 at the joints 22. (6) While the sheet 18 is being relaxed, the connecting pieces 24 are removed from the pipes 12 at both ends. (7) By performing the above steps, the seat 18 can be completely separated from the frames 14 and 16. When attaching the seat 18 to the cot 10, the above steps may be carried out in reverse order.
