Hammock

Abstract

With conventional cloth hammocks, when a person lies thereon and the fabric is pulled taut in the cloth-length direction, suitable elasticity cannot be achieved, leading to poor comfortability. According to the present invention, a forced crimping unit (11) forcibly produces crimping (wrinkles) to create suitable elasticity so that an impact on a human body by way of the movement is eased; and a design of adjusting level differences (32) thus produced to meet with the contours of the human body reduces variation in the weight distribution on the human body, thereby improving the comfortability. Moreover, a hooked clip (18), which is a component of the forced crimping unit (11), moves flexibly in response to the loading, thereby preventing damage to the cloth of the hammock and improving durability.

Claims

1. A fabric-made hammock that forcibly produces crimping, comprising: a fabric-made hammock having a base cloth in a rectangular shape with a cloth-length direction and a cloth-width direction, and one or a plurality of forced crimping units for forcibly producing crimping in the base cloth, each forced crimping unit constituted of two cloth-pinching wood pieces of an identical shape and a hooked clip, the cloth-pinching wood pieces each being a rectangular wooden plate with a clip-fixing notch provided on one side of the rectangular wooden plate, the hooked clip comprising a folded a sheet of rectangular metal plate forming a U-shape constituted of a clip upper wall and a pair of symmetric clip side walls extending from ends of the clip upper wall, being in a closed state, with the clip upper wall and each of the clip side walls forming an acute angle therebetween so that ends of the opposing clip side walls are in contact with each other, allowing the opposing clip side walls to be in an open state when a clip-opening force is applied outward to each of the opposing clip side walls, and having fixing hooks comprising bent extremities of the opposing clip side walls inward at a right angle, the two cloth-pinching wood pieces in each forced crimping unit being fixed to the base cloth with an adhesive so as to be arranged symmetrically with respect to a cloth-folding centerline that is parallel with the cloth-length direction with the clip-fixing notch directed outward, being layered with each other, with the base cloth interposed therebetween, and being attached with the hooked clip in an open state so as to be embraced by the hooked clip, with the fixing hook of the hooked clip tightly fitted to a top face of the clip-fixing notch so that the fixing hook of the hooked clip does not shift on the top face of the clip-fixing notch, thereby arranging each forced crimping unit to form a piece of crimping in the base cloth in parallel with the cloth-length direction, wherein the one or a plurality of the forced crimping units are arranged on the base cloth at an optional interval on a straight line in parallel with the cloth-width direction to form a forced crimping unit zone in which the crimping is formed in the base cloth in parallel with the cloth-length direction in a number corresponding to the number of the forced crimping units, and wherein elastic deformation plays a role in an opening and closing operation of the clip side walls of each hooked clip being made of metal when the hammock is in use.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 illustrates a conventional two-support point fabric-made hammock.

(2) FIG. 2 illustrates a four-support point simple fabric hammock (Japanese Unexamined Patent Application, Publication No. 2017-196436).

(3) FIG. 3 illustrates a hammock body of the four-support point simple fabric hammock (Japanese Unexamined Patent Application, Publication No. 2017-196436).

(4) FIG. 4 illustrates a hammock according to an embodiment of the present invention (non-loaded).

(5) FIG. 5 illustrates cloth-pinching wood pieces set on the base cloth of the four-support point simple fabric hammock.

(6) FIG. 6 illustrates a cloth-pinching wood piece.

(7) FIG. 7 illustrates attachment of a hooked clip (to one piece of the forced crimping unit).

(8) FIG. 8 illustrates operations of the hooked clip.

(9) FIG. 9 illustrates attachment of the hooked clips (to the entire hammock).

(10) FIG. 10 illustrates the hammock according to the embodiment of the present invention in a loaded state.

(11) FIG. 11 illustrates a side elevation of the hammock according to the embodiment of the present invention with a person lying thereon.

DESCRIPTION OF EMBODIMENTS

(12) As described above, the embodiment of the present invention can be applied to the typical two-support point fabric-made hammock in FIG. 1, the four-support point simple fabric hammock in FIG. 2, and the like. The characteristics of these hammocks are that the hammock body (1) is made of fabric, and that the hammocks have the crimping (wrinkles) (end crimping (10)) that originates in the coupling portions, in which the base cloth (4) is coupled to the mediums that respectively couple the hammock body (1) to the suspension support points (3) (the mediums being the suspension ropes (2) for the two-support point fabric-made hammock, and the two-support point coupling chains (7) and the protective hoses (6) for the four-support point simple fabric hammock), that is, the both ends of the base cloth (4) in the cloth-length direction (8).

(13) The size and the quantity of the forced crimping units (11) and the interval therebetween in the forced crimping unit zone (12) are optional. The hammock shape in the lateral width direction is to be designed by adjusting these figures to improve comfort of a person lying on the hammock.

(14) FIG. 11 illustrates an example in which the forced crimping unit zone (12) is applied to the waist portion, but the forced crimping unit zone (12) can also be adapted to another portion of the hammock where a recessed body part (such as the neck) of a person is situated when he lies thereon.
