Folding bed

Abstract

The invention relates to a folding bed, which comprises mattress fabrics and a bracket. The bracket is provided with two side vertical surfaces, and related vertical surfaces, which are connected with the two side vertical surfaces, wherein each of the two side vertical surfaces is provided with three groups of oblique rod units, including two end oblique rod units and a middle oblique rod unit; the two end oblique rod units are hinged together with an oblique rod unit in the related vertical surface through an upper angle plate and a lower angle plate; a vertical rod is movably positioned on a crossed hinging point of two oblique rods in the two end oblique rod units; a connecting plate is hinged on the upper end part of the vertical rod; horizontal rods are respectively hinged in two horizontal directions of the connecting plate; the other end of each horizontal rod penetrates through the upper angle plate of the vertical surface on the same side and is hinged with the upper angle plate; one horizontal rod in the two end oblique rod units extends to the end part of the middle oblique rod unit and is hinged with the end part through a hinge plate; the end parts of the oblique rods in the middle oblique rod unit are hinged on the oblique rods in the two end oblique rod units; and both sides of the mattress fabrics are positioned on the horizontal rods of the two side vertical surfaces. The folding bed has the advantages of reasonable proportion of length to width of a bed body, stable support on both ends and neat height after folding.

Description

Technical field: [0001] The invention belongs to the field of daily necessities, and particularly relates to a folding bed suitable for travel and leisure, outdoor sports, field operations, or provision of rest in temporary places. Background technique: [0002] The existing camp bed evolved from a folding chair, and its structure includes a mattress fabric and a bracket. For example, the patent number CN02228784.1 provides a camp bed. The relationship between the brackets of the camp bed is as follows: Image 6 As shown, it is divided into two sides (called by people) and four facades on both sides. Each facade contains two diagonal rods 2 that cross each other and are hinged together. The diagonal rod 2 and the upper and lower two adjacent diagonal rods 2 The ends are hinged to form a bracket as a whole; the elevations on both sides are symmetrical, and are respectively hinged by two sets of inclined rods through the upper and lower corner plates 3 and 4 in the middle, and the c...

Problems solved by technology

The biggest feature of this patent is that both sides of the mattress fabric can get balanced support, which improves the support structure for the human body and makes rest more comfortable. The disadvantage is that the two sides of the bracket are only hinged by two sets of diagonal rods The bed body is short, and the crossbars or oblique bars at both ends need to be properly extended to support the head and feet at the same time. As a result, the extended section of the bar is higher than the whole body after folding, which is not conducive to storage and carrying. Second, the extended part cannot bear the weight of the human body, that is, people cannot sit on the two ends, otherwise the folding bed will tilt up, posing a safety hazard
