Adjustable mattress structure

Abstract

An adjustable mattress structure comprises a mattress body in which there are a plurality of hollow bases, a plurality of elastic support units, a plurality of adjustable positioning boards and a plurality of spring positioning bodies. Each of the elastic support units consists of a first encapsulated elastomer and a second encapsulated elastomer. The first encapsulated elastomer depends on spring positioning bodies to be fixed on one of the hollow bases so that the second encapsulated elastomer extends inside the hollow base. Each of the adjustable positioning boards is fixed inside a hollow base and used to receive a second encapsulated elastomer; the adjustable positioning boards in the hollow bases are situated at distinct positions by which the adjustable positioning boards make the elastic support units generate distinct resilient bearing capacities for adjustable mattress firmness supporting a body curve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) The technical contents, features and effects related to an adjustable mattress structure are clearly presented in preferred embodiments and accompanying drawings.

(10) Referring to FIGS. 1, 2 and 3 which illustrate partial components of an adjustable mattress structure. As shown in these figures, the adjustable mattress structure comprises a mattress body 100 in which there are a plurality of hollow bases 1, a plurality of elastic support units 2, a plurality of adjustable positioning boards 3 and a plurality of spring positioning bodies 4. The hollow bases 1 are arranged in place for development of the length and the width of the mattress body 100. Each of the hollow bases 1 has a top surface 11 on which openings 111 are designed and an anterior side 12 on which an opening 121 is designed and is internally connected through the openings 111, 121. At both sides of an opening 111 on the top surface 11 are opened two sliding grooves 112; on both lateral walls inside the hollow base 1 are designed several slide seats 13 symmetrically arranged from top to bottom for development of a positioning mechanism by which an adjustable positioning board 3 is adjusted in height.

(11) As shown in FIGS. 1 to 3, an adjustable positioning board 3, which slips into slide seats 13 through an opening 121 on an anterior side 12 of a hollow base 1, is coupled with and positioned in the slide seats 13 according to an optional height. As such, the adjustable positioning boards 3 in all hollow bases 1 are situated at same or distinct heights.

(12) As shown in FIGS. 1 to 3, an elastic support unit 2 placed on the top surface 11 of a hollow base 1 comprises a first encapsulated elastomer 21 on which there are a top 211 as well as a bottom 212 and a second encapsulated elastomer 22 on which there are a top 221 as well as a bottom 222. The top 221 of the second encapsulated elastomer 22 joins the top 211 of the first encapsulated elastomer 21 so that the second encapsulated elastomer 22 is suspended and positioned in the first encapsulated elastomer 21 and allows the bottom 222 to extend from the bottom 212 of the first encapsulated elastomer 21.

(13) Moreover, second encapsulated elastomers 22 suspended in first encapsulated elastomers 21 are an example in a preferred embodiment which does not limit claims herein. A design of second encapsulated elastomers 22 held in first encapsulated elastomers 21 should be incorporated in claims herein.

(14) As shown in FIGS. 1 to 3, a first encapsulated elastomer 21 (a second encapsulated elastomer 22) illustrates at least a spring is wrapped in an encapsulated package. (In FIGS. 1 to 3, an encapsulated package made of non-woven fabric or other textile materials is indicated with dotted lines in which coil icons as a spring are wrapped.)

(15) The spring positioning body 4 comprises a locating part 41 from which a first elastic fastener 42 and a second elastic fastener 43 at both sides extend: the first elastic fastener 42 and the second elastic fastener 43 at tops are provided with a fastening block 421 and a fastening block 431, respective; the first elastic fastener 42 and the second elastic fastener 43 develop a fastening space in between; the spring positioning body 4 comprises two sliding parts 45 extending from the bottom of the locating part 41. The spring positioning body 4 allows two sliding parts 45 to slip into the sliding grooves 112 on the top surfaces 11 of two adjacent hollow bases 1 and be positioned beside the openings 111 so that the two adjacent hollow bases 1 are not separated from each other. Moreover, the fastening block 421 on the first elastic fastener 42 (the fastening block 431 on the second elastic fastener 43) clasps one side of one in two adjacent first encapsulated elastomers 21 so that the two adjacent first encapsulated elastomers 21 are positioned in the fastening space 44 of the spring positioning body 4. As such, a first encapsulated elastomer 21 is stably fixed on the top surface 11 of a hollow base 1, a second encapsulated elastomers 22 extends into the hollow base 1 through an opening 111 on the top surface of the hollow base 1, and each elastic support unit 2 is positioned on the top surface 11 of a hollow base 1.

(16) When the elastic support unit 2 is placed on the top surface 11 of the hollow base 1, the bottom 212 of the first encapsulated elastomer 21 contacts the top surface 11 of the hollow base 1 and the bottom 222 of the second encapsulated elastomer 22 penetrates the opening 111 on the top surface 11 of the hollow base 1 and is situated above or resisted by the adjustable positioning board 3.

(17) As shown in FIG. 1, two adjacent hollow bases 1, which have been linked and positioned by sliding parts 45 of spring positioning bodies 4 when all elastic support units 2 are placed on top surfaces 11 of the hollow bases 1, combine each other. Based on the above mechanism, a mattress body 100 which is covered with a mattress encasement 5 can be developed finally.

(18) Referring to FIG. 4 which illustrates a layer of spacer member 46 adheres to two adjacent hollow bases 1 or a layer of spacer member 46 between two sliding parts 45 of a spring positioning body 4 extends downward in order to avoid friction-induced noise between two adjacent hollow bases 1. Other structural components identical to those in FIG. 3 are not further explained.

(19) Referring to FIG. 5. Different from FIGS. 1 to 3, FIG. 5 illustrates an elastic carrier 6 integrated with a hollow base 1 internally has two ends fixed at two opposite sides of the hollow base 1 lengthwise and is situated at the topmost end inside the hollow base 1 and above highest slide seats 13. The elastic carrier 6 is used to receive second encapsulated elastomers 22, which are moving downward and not sinking to the bottom of the hollow base 1 directly, and prevent an adjustable positioning board 3 from slipping into the hollow base 1 completely. Moreover, a second encapsulated elastomer 22 which is pressed downward under stress overcomes elasticity of the elastic carrier 6, keeps moving downward and resists an adjustable positioning board 3 without failure of any initial function. Other structural components identical to those in FIGS. 1 to 3 are not further explained.

(20) Additionally, the sliding parts 45 of spring positioning bodies 4 correspondingly slide inside but do not directly deviate from the sliding grooves 112 which are designed as dove-shaped grooves on the hollow base 1.

(21) Referring to FIG. 6. Different from FIGS. 1 to 3, FIG. 6 illustrates no spring positioning body 4 but a positioning slot 113 around an opening 111 at the top surface 11 of a hollow base 1 directly. The bottom 212 of a first encapsulated elastomer 21 is directly coupled with and positioned in the positioning slot 113 so that the first encapsulated elastomer 21 is peripherally positioned at the opening 111 of the hollow base 1. Other structural components identical to those in FIGS. 1 to 3 are not further explained.

(22) Referring to FIG. 7. Different from FIGS. 1 to 3, FIG. 7 illustrates no spring positioning body 4 but a clamping member 114 around an opening 111 at the top surface 11 of a hollow base 1 directly. The clamping member 114 clasps coils of a first encapsulated elastomer 21 near the bottom 212 so that the first encapsulated elastomer 21 is peripherally fixed at the opening 111 of the hollow base 1. Other structural components identical to those in FIGS. 1 to 3 are not further explained.

(23) As shown in FIG. 8, the first encapsulated elastomers 21 of the elastic support units 2 support weight of a user 7 who lies down the mattress body 100, making the second encapsulated elastomers 22 under stress move downward and resist the adjustable positioning boards 3. Because each of the adjustable positioning boards 3 inside one hollow base 1 is manually adjustable in height based on a body curve, distinct positions (areas) on the body of a user 7 correspond to adjustable positioning boards 3 inside hollow bases 1 at different heights: a second encapsulated elastomer 22 is less elastically compressed when stress is propagated from the top 221 of the second encapsulated elastomer 22 which has the bottom 222 close to the adjustable positioning board 3; a second encapsulated elastomer 2 performs different elasticity by which each elastic support unit 2 generates distinct elastic force when a distance between the bottom 222 of the second encapsulated elastomer 22 and an adjustable positioning board 3, which is moved downward and located at a distinct position in a hollow based 1, is increased. As such, a user 7 whose body curve is adjustably supported by the mattress body 100 based on mattress firmness will sleep comfortably.

(24) The preferred embodiments hereof should not be taken as examples to restrict the scope of an adjustable mattress structure in the present disclosure. The equivalent changes and modifications made by the skilled person who familiarizes himself with the above technical features and embodiments without departing from the spirit and scope of the present disclosure should be covered in claims of the patent specification.
