Abstract
Description
Technical Field
[0001] This utility model relates to the field of home furnishings, and in particular to a modular adjustable mattress. Background Technology
[0002] As a primary home furnishing item for rest, mattresses are typically sized to fit the size of the bed, and their width and height are usually not adjustable. This makes it inconvenient for users to temporarily widen the mattress.
[0003] To address the aforementioned issues, patent application number 201620104885.4 discloses an adjustable mattress, comprising a mattress base and an elastic surface pad disposed on the upper surface of the mattress base. The elastic surface pad includes a left surface pad and a right surface pad, with a widened surface pad disposed between the left and right surface pads. Both the left and right surface pads are laterally slidable relative to the mattress base. The left and right surface pads are laterally provided with several corresponding interlocking holes. The left surface pad, the widened surface pad, and the right surface pad are connected by several connecting straps, and a limiting mechanism is provided between the connecting straps and the left and right surface pads.
[0004] The mattress base described above has a cavity in the middle to accommodate a wider mattress pad, allowing for temporary widening and ease of use. However, its structure is complex and its cost-effectiveness is not high.
[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
[0006] The purpose of this invention is to provide a modular adjustable mattress to address the shortcomings of existing technologies.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0008] An adjustable mattress with interlocking features includes a support mattress, interlocking mattresses, height fasteners, and width fasteners.
[0009] One side of the supporting mattress is the supporting surface, and the other side of the supporting mattress is the splicing surface. Both sides of the splicing mattress are splicing surfaces. A height splicing groove is provided on the splicing surface, which runs through the width direction. Width splicing grooves are provided at both ends of the height splicing groove. The width splicing groove runs through the side of the supporting mattress or the splicing mattress.
[0010] The height fastener includes an integrally connected upper connecting part and a lower connecting part, the shapes of which are adapted to the shape of the height splicing groove;
[0011] The width fastener includes an integrally connected upper and lower connecting ends, the shapes of which are adapted to the shape of the width splicing groove.
[0012] Furthermore, the supporting mattresses are respectively positioned at the top and bottom, and several spliced mattresses are stacked vertically between the supporting mattresses. The height splicing grooves on the adjacent splicing surfaces form a height receiving groove, and the height fasteners are set in the height receiving groove, connecting and fixing the adjacent supporting mattresses and spliced mattresses or two adjacent spliced mattresses.
[0013] Furthermore, both the supporting mattress and the spliced mattress are provided in two pieces, with the spliced mattress horizontally positioned below and the supporting mattress horizontally positioned above the spliced mattress.
[0014] The width splicing grooves of horizontally adjacent support mattresses or spliced mattresses form a width receiving groove. Width fasteners are set in the width receiving groove and connect and fix horizontally adjacent support mattresses or spliced mattresses.
[0015] The height-fitting grooves of the stacked support mattresses and the interlocking mattresses form a height-accommodating groove. The height-fitting fasteners are installed in the height-accommodating groove and connect and fix the stacked support mattresses and the interlocking mattresses.
[0016] In summary, this utility model has the following beneficial effects:
[0017] The support mattresses and interlocking mattresses used have different firmness levels, allowing users to choose according to their preferences. They can also be interlocked into mattresses of different heights and widths using height and width fasteners. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.
[0027] like Figures 1 to 6 As shown, the present invention proposes a modular adjustable mattress, which includes a supporting mattress 1, a modular mattress 2, a height fastener 3, and a width fastener 4.
[0028] One side of the supporting mattress 1 is the supporting surface 11, and the other side of the supporting mattress 1 is the splicing surface 12. Both sides of the splicing mattress 2 are splicing surfaces 12. A height splicing groove 5 is provided on the splicing surface 12, which runs through the width direction. Width splicing grooves 6 are provided at both ends of the height splicing groove 5. The width splicing grooves 6 run through the side of the supporting mattress 1 or the splicing mattress 2.
[0029] The height fastener 3 includes an integrally connected upper connecting part 31 and a lower connecting part 32, the shapes of which are adapted to the shape of the height splicing groove 5;
[0030] The width fastener 4 includes an integrally connected upper connecting end 41 and a lower connecting end 41, the shapes of which are adapted to the shape of the width splicing groove 6.
[0031] The supporting mattresses 1 are respectively set at the top and bottom. Several spliced mattresses 2 are stacked on top of each other between the supporting mattresses 1. The height splicing grooves 5 set on the adjacent splicing surfaces 12 form a height receiving groove. The height fasteners 3 are set in the height receiving groove and connect and fix the adjacent supporting mattresses 1 and spliced mattresses 2 or two adjacent spliced mattresses 2.
[0032] The supporting mattress 1 and the spliced mattress 2 are each provided in two pieces, with the spliced mattress 2 horizontally positioned below and the supporting mattress 1 horizontally positioned above the spliced mattress 2.
[0033] The width splicing grooves 6 of the horizontally adjacent support mattress 1 or spliced mattress 2 form a width receiving groove, and the width fastener 4 is set in the width receiving groove and connects and fixes the horizontally adjacent support mattress 1 or spliced mattress 2.
[0034] The height splicing groove 5 of the stacked support mattress 1 and spliced mattress 2 forms a height receiving groove, and the height fastener 3 is set in the height receiving groove to connect and fix the stacked support mattress 1 and spliced mattress 2.
[0035] The working principle of this utility model is as follows:
[0036] The support mattress and the interlocking mattress have different levels of firmness, which users can choose according to their preferences. They can also be spliced together to form mattresses of different heights and widths using height and width fasteners.
