Description

[Detailed Description of the Invention] The present invention relates to a frame structure of a canvas chair that also serves as a hammock-like bed.

Conventionally, the so-called canvas chair uses a flexible material such as canvas as a sheet member,
There is a chair that can be used not only as a normal chair but also as an easy chair by changing the inclination angle of the backrest frame, but in the conventional chair, the inclination angle of the backrest frame is simply changed. Because of this, even if the backrest frame is tilted to its maximum extent, the seat surface will be slightly longer than in the case of a normal chair, and therefore a separate footrest must be prepared in order to place the feet up to the feet. There is an inconvenience that it must be done.

Therefore, in this invention, in addition to the form of a normal chair, we have developed a canvas chair that doubles as a hammock-like bed, which can be changed to a hammock-like bed on which you can sleep with your entire body, including your feet. The purpose is to provide a frame structure, and its gist is to provide a base, a molded backrest frame,
It consists of a seat frame body whose outer width is narrower than the inner width of the backrest frame body, and the backrest frame body and the lower end of the seat frame body can be rotated in the front-rear direction relative to the base while separating the lower ends of the seat frame body by a required distance from each other. A locking means is provided which is pivotally attached in a freely pivotable state and locks both frames in a crossed state at the base end of the backrest frame body and the midway part near the base end of the seat frame body, and contrary to the above. The frame structure of the canvas chair, which also serves as a hammock-like bed, is characterized in that it is provided with stopper members that support both frames in a state in which they are opened in an inclined manner in the front-rear direction.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 5 show an embodiment of the present invention. In the figures, A is a base, B is a backrest frame, and C is a backrest frame.
indicates a seat frame body, and D indicates a flexible sheet member.

The base A is formed into a substantially H-shape, and bearing stands 1 are erected at the rear portions of both left and right sides of the base A. The backrest frame B has a shape with a large internal opening, and the lower ends of its left and right sides are pivotally connected to the approximately middle part of the base A, that is, to the outer surface of the tip of the bearing pedestal 1. The seat frame C is provided so as to be freely rotatable in the front and back direction about a center, and the seat frame C has a substantially rectangular shape whose outer width is narrower than the inner width of the opening of the backrest frame B. The lower end portions are each pivotally connected to the rear portion of the base A, that is, to the inner surface of the rear end portion of the bearing stand 1, and are provided in a state where they can freely rotate in the front and rear directions about the pivot portion b. Therefore, the seat frame C passes through the opening of the backrest frame B and is in a state where it can freely rotate in the front-rear direction.

Also, in the figure, E is a locking means for locking both frames B and C in a crossed state to form a normal chair, and is located near the proximal end between the left and right sides of the backrest frame B. It is composed of an engaging piece 2 provided on the seat frame C, and a plurality of engaging grooves 3 formed on the front side of the midway part near the base end of both left and right sides of the seat frame body C, and the engaging piece 2 and the engaging groove 3 When engaged with the chair, it takes on the form of an ordinary chair.

Contrary to the above, F and F' are stopper members that support both frames B and C in a state in which they are opened greatly in the front and back direction, and the stopper member F of the backrest frame B is the stopper member of the same backrest frame. In order to enable folding of B, it is detachably attached to base A.

Next, the flexible sheet member D is made of a strong flexible material such as canvas, and its one end edge is attached to the upper piece of the backrest frame B, while the other edge is attached to the front piece of the seat frame C. Therefore, when both frames B and C are opened in the front-rear direction as shown by the dashed line in FIG. 2, there is a sheet member D between the upper and front pieces of both frames B and C. is stretched, forming a hammock-shaped bed with sufficient length. In addition, a locking piece 4 is provided on the front surface of the midway portion of the left and right sides of the seat frame C, and the free ends of the left and right edges of the flexible sheet member D, which are substantially opposite to the locking piece 4, are provided. A base end portion of a connecting belt 6 having an engaging hole 5 that can be engaged with and detached from the locking piece 4 is fixedly attached to the flexible seat member D in the form of an ordinary chair. The extra length c of the seat frame body C
It serves the purpose of pulling it into the back side of the screen.
That is, changing from the hammock-like bed shape shown by the dashed line in FIG.
This is done by passing through the opening of the backrest frame B and rotating it forward, and engaging the engaging piece 2 and the engaging groove 3 with each other. However, before performing the above changing operation, If the locking piece 4 is engaged with the engagement hole 5 of the connecting belt 6 in advance, the extra length c of the flexible sheet member D is automatically pulled into the back side of the seat frame C. This creates a seat surface of an appropriate length, allowing it to be used as an ordinary chair.

6 and 7 show other attachment structures for the flexible sheet member D. First, FIG. 6 shows the locking piece 4 and the connecting belt 6 in the above embodiment.
Instead, a case is shown in which one end edge of the flexible sheet member D is fixedly attached to the middle part of the seat frame C in advance, and then in FIG. In addition to providing the stopper piece 7, the flexible sheet member D
The engagement hole (not shown) provided in the middle of the locking piece 7
The case is shown in which it is engaged with. Note that 8 in FIG. 7 is a string that serves to pull up the extra length c of the flexible seat member D in the form of a normal chair to the back side of the seat frame C so that it does not get in the way. .

As explained in detail above, according to the present invention, it is possible to change the form from a normal chair to a hammock-like bed on which you can sleep with your entire body, including your feet. Therefore, it is possible to sleep in an extremely comfortable state without using a separate footrest as in the conventional case, and the structure is simplified and handling is convenient.
