Description

Technical Field

[0001] This utility model belongs to the field of mattresses, specifically relating to a mortise and tenon structure sponge frame and mattress. Background Technology

[0002] Most existing mattresses consist of a core layer, a filling layer, and a quilted layer. It's difficult to avoid the presence of glue in existing mattresses, which is mainly distributed in three places: 1. The core layer (pocket mattress core) is bonded with hot melt adhesive; 2. The filling layer, where the layers are mostly fixed using spray adhesive; 3. The raw materials themselves contain glue.

[0003] Since adhesives typically contain formaldehyde, they pose a safety hazard to sleep health. Furthermore, materials are easily damaged during disassembly due to the adhesive binding, resulting in low recycling rates and hindering future maintenance. Summary of the Invention

[0004] This invention addresses the shortcomings of existing mattresses that rely heavily on glue by providing a mortise and tenon structure for the foam frame. This design eliminates the need for glue by using mortise and tenon joints, thus avoiding or reducing glue usage. Furthermore, this mortise and tenon structure differs from the support layer frame of existing mattresses. This invention also provides a mattress using this mortise and tenon structure for the foam frame.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mortise and tenon structure sponge frame, wherein the mortise and tenon structure sponge frame includes:

[0006] First border strip;

[0007] Second border strip;

[0008] The first edge strip has two ends forming a first mortise and tenon joint, and the second edge strip has two ends forming a second mortise and tenon joint. The first and second mortise and tenon joints are mating tenons and mortises, and the tenons are horizontally positioned.

[0009] The mortise and tenon structure sponge frame of this utility model includes a first edge strip and a second edge strip, which are connected by mortise and tenon joints, thus eliminating the need for glue; the tenon is set horizontally, which can ensure that the first edge strip and the second edge strip do not misalign in the height direction, thus ensuring the user experience.

[0010] As an improvement, the first mortise and tenon joint is an open through tenon, the second mortise and tenon joint is a through mortise; the first mortise and tenon joint is a double-shoulder tenon.

[0011] As an improvement, both first mortise and tenon joints at both ends of the first edge strip are tenons, and both second mortise and tenon joints at both ends of the second edge strip are mortises; or, the two first mortise and tenon joints at both ends of the first edge strip are tenons and mortises respectively, and the two second mortise and tenon joints at both ends of the second edge strip are tenons and mortises respectively.

[0012] As an improvement, the mortise and tenon structure sponge frame includes two identical first edge strips and two identical second edge strips; the density of the mortise and tenon structure sponge frame is 25kg~45kg / m³, and the compression hardness is 150N~300N.

[0013] The mattress includes a support layer, which includes a border frame and a mattress core within the border frame, wherein the border frame is the aforementioned mortise and tenon structure foam border.

[0014] As an improvement to the mattress, the support layer also includes a cover, with the edge trim and core all housed within the cover.

[0015] As an improvement to mattresses, the cover includes a zipper and is secured to the mattress core with soft nails.

[0016] As an improvement to the mattress, the core is a glue-free pocketed core, which includes a steel edging and multiple pocketed springs, which are ultrasonically welded together; or, the core is a glue-free Bonnell core.

[0017] As an improvement to the mattress, the side frame is fixed to the mattress core by straps and hard nails at the top and bottom ends; each side of the side frame has a first strap, or multiple second straps on each side of the side frame.

[0018] As an improvement to the mattress, the mattress is a glue-free mattress with a glue-free core. The mattress also includes a quilted layer and a comfort layer. The quilted layer includes a quilted upper layer, a quilted lower layer, and a zipper. The comfort layer includes an inner cover and a glue-free inner core within the inner cover. The inner cover includes a zipper. The comfort layer is located above the core, and the quilted layer wraps around the core and the comfort layer.

[0019] The beneficial effects of the mortise and tenon structure sponge frame of this utility model are: the first and second edge strips are connected by mortise and tenon joints, thus eliminating the need for glue; the tenon is set horizontally, which can ensure that the first and second edge strips do not misalign in the height direction, thus ensuring the user experience.
