Abstract
Described are wooden coil springs, including those made of non-compressed wood, and mattresses with such coil springs. Also described is a method of producing a coil spring made of non-compressed wood, which includes winding a slat on reel, steaming and drying to produce the wooden coil spring. Such a coil spring may have a cylindrical shape, a cone shape or a truncated cone shape, and may have a substantially perpendicular end turn with respect to the longitudinal axis of the coil spring.
Claims18
A mattress including a wooden coil spring made of a slat of wood having, at a first point of the slat, a cross section with rectilinear major sides with a first value as a first dimension, and having, at a second point remote in the longitudinal direction of the slat from the first point, a cross section with rectilinear major sides with a second value as the first dimension, the first value being greater than the second value,
- wherein the coil spring is made of non-compressed wood.
A mattress including a wooden coil spring made of a slat of wood having, at a first point of the slat, a cross section with rectilinear major sides with a first value as a first dimension, and having, at a second point remote in the longitudinal direction of the slat from the first point, a cross section with rectilinear major sides with a second value as the first dimension, the first value being greater the second value, wherein the mattress further comprises:
- a first plurality of wooden coil springs positioned in a first area of the mattress and a second plurality of wooden coil springs positioned in a second area of the mattress different from the first area,
- wherein the first plurality of wooden coil springs provides a firmness firmer than the second plurality of wooden coil springs,
- wherein the coil spring is made of non-compressed wood.
A mattress including a wooden coil spring made of a slat of wood having, at a first point of the slat, a cross section with rectilinear major sides with a first value as a first dimension, and having, at a second point remote in the longitudinal direction of the slat from the first point, a cross section with rectilinear major sides with a second value as the first dimension, the first value being greater the second value,
- wherein the coil spring has a cylindrical shape, and
- wherein the wooden coil spring comprises:
- (1) an end turn wider than an end turn of a second coil spring in the mattress, and
- (2) remaining turns having substantially the same widths as the remaining turns of the second wooden coil spring,
- wherein the coil spring is made of non-compressed wood.
