RELATED APPLICATIONS

This application claims priority to Chinese patent application 202310651825.9, filed on Jun. 2, 2023. Chinese patent application 202310651825.9 is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to an elastic cushion having springs, and in particular relates to an elastic cushion with a non-rigid connection between the springs.

BACKGROUND OF THE DISCLOSURE

Existing elastic cushions made of springs require a plurality of the springs to achieve elastic support. Generally, upper ends of the springs are connected together, or a sponge having an appropriate thickness is laid on the upper ends of the springs, so that force is dispersed when the springs are compressed. When the plurality of the springs are compressed, the plurality of the springs are linked for support. Flexible support of a human body needs an elasticity of the springs to change according to a posture change of the human body. An elasticity of the springs, as a whole, cannot enable the human body to stretch in various postures, and different parts of the human body may require variable hardnesses. In addition, different people desire and require variable hardnesses. In existing beds having variable hardnesses, the hardness of the beds are adjustable due to various deformation degrees generated by the springs. A deformation member enables the springs to deform independently from deformation of the springs caused by the human body. That is, during initialization time, the hardness of the beds is adjustable according to wishes of the user. The hardness of the bed can also be compensated for possible changes in elastic properties of the springs in a random pattern. However, common problems of these existing beds having variable hardnesses are that the existing beds having variable hardnesses are relatively complex, heavy, and expensive to produce. These existing beds are also relatively difficult and cumbersome for use. Further, even if these existing beds provide a certain degree of adjustability, it is usually not user-friendly and leads to a lot of trouble for the producers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

An elastic cushion 10 of Embodiment 1 is shown in FIGS. 1-4. The elastic cushion 10 comprises a spring module (i.e., an elastic module) 2, and the spring module 2 comprises springs 21 and a flexible band (e.g., webbing 3). Two adjacent rows of the springs 21 define a staggered arrangement. The springs 21 are wrapped by cloth sleeves 22, or the springs 21 are independent springs pocketed in bags. Preferably, the springs 21 are anti-waisted drum springs (i.e., waist-shaped springs). That is, diameters of waists of the springs 21 are smaller than diameters of ends of the springs 21 (e.g., small than diameters of at least one end of each of the springs 21). Middle parts (i.e., waists) of the springs 21 comprise fixing seats 6, and the springs 21 of the spring module 2 are arranged as shown in FIGS. 5A, 5B, and 5C. Referring to FIG. 6, a series connection of the webbing 3 is as follows: the springs 21 contact or are close to one another to be arranged in rows in a lateral direction, two adjacent rows of the rows are staggered, and at least two opposing sides of the fixing seats 6 comprise perforations 61. The two adjacent rows of the springs are staggered to enable the perforations 61 in the fixing seats 6 to be connected in series to form a substantially continuous straight line 62. The webbing 3 passes through the perforations 61 in the substantially continuous straight line 62, and two ends of the webbing 3 comprise stoppers 5 or buckles, so that the two adjacent rows of the springs 21 are connected in series. In this way, the webbing 3 connects the springs 21 of the two adjacent rows of the springs 21 in series, so that compressed springs 21 in a first row of the two adjacent rows and uncompressed springs 21 in a second row of the two adjacent rows are forced in series without creating large gaps. Preferably, first ends of the stoppers 5 are configured to be fixed to the webbing 3, and second ends of the stoppers 5 are configured to be detachably fixed to the webbing 3.

A bottom side of the spring module 2 can be fixed on a rigid or flexible base plate 20.

The fixing seats 6 comprises a stop structure 63. The stop structure 63 cooperates with the stoppers 5 of the webbing 3 to fix the webbing 3, and an outside of the two ends of the webbing 3 comprise stop positions 31 for receiving the stoppers 5.

An elastic mattress (i.e., spring mattress) made of the spring module 2 is shown in FIG. 1. The elastic mattress comprises a top layer 1 and a peripheral fixing webbing 4, and the peripheral fixing webbing 4 loops an outer periphery of the spring module 2 together. The top layer 1 comprises side edges 11, and the side edges 11 can be snapped to the fixing seats 6 of the springs 21 or the rigid or flexible base plate 20 of the spring module 2.

Embodiment 2

Referring to FIG. 7, this embodiment differs from Embodiment 1 in that the two adjacent rows of the springs 21 in the spring module 2 are respectively aligned with each other, a single row of the two adjacent rows of the springs 21 are connected in series using the webbing 3, and the fixing seats 6 of the two adjacent rows of the springs 21 are snapped together or connected by a third piece. In this way, the single row of the two adjacent rows of the springs 21 are connected in series by the webbing 3, and different rows of the two adjacent rows of the springs 21 are connected by the fixing seats 6. The springs 21 deform independently while obstructing each other without moving away from each other.

An arrangement of the springs 21 and connectors of Embodiments 1-2 do not limit the spring module 2 and the elastic cushion 10 made therefrom of the present disclosure, and the spring module 2 can be made using other arrangements by a person of skill in the art. The connectors are not limited to only those specified in Embodiments 1-2, and the present disclosure covers any modifications and variations of the presently presented embodiments provided the springs 21 are connected by the flexible band. The elastic cushion 10 can be made using the spring module 2 in various ways as well.
