The present disclosure relates to the technical field of outdoor camping equipment, and in particular relates to an elastic mattress.
As society increasingly progresses and living standards of people increasingly improve, outdoor sports are becoming increasingly popular and have become an important part of daily lives and entertainment of people. When camping outdoors, the inevitable question is: “How to sleep at night?”, and how to sleep comfortably outdoors without a household large mattress.
The term “sleeping cushion” is used in camping to refer to an object as a bed mattress. A function of an outdoor sleeping cushion is to provide warmth, comfort, and dehumidification. The comfort is an important factor for having a good night outdoors. No matter how flat the outdoor environment, there will inevitably be uneven surfaces such as pebbles and tree stumps. Sleeping directly on the ground is bound to be uncomfortable. With respect to sleeping comfort options, the most common sleeping cushion is an air mattress that is inflatable to be easy to transport. However, the softness, firmness, and elasticity of the air mattress is still incomparable to that of a household large spring mattress. In addition, the air mattress needs to be inflated, and certain safety risks exist in use due to air leaks.
The reason why large elastic bed mattresses cannot be used outdoors is mainly due to weight and storage size. The weight and the storage size determine whether the mattress is easy to transport, as space in a car trunk is always limited. Most bed mattresses on the current market use springs as a modular structure of the bed mattress, and sizes of the bed mattress are generally designed to fit standard sizes corresponding to the beds, such as 1.5 m×1.9 m or 1.8 m×2.0 m. As the bed mattresses have large sizes and cannot be folded or disassembled so as to be very inconvenient to transport and store, the elastic bed mattresses having the springs as the bed mattress modular structure are particularly difficult to take out for outdoor camping for a person enjoying outdoor activities.
The main technical problem to be solved by the present disclosure is that bed mattresses using springs as bed mattress modules cannot be used for camping. Therefore, the present disclosure provides an elastic mattress that forms an open-type bed mattress, which can be easily disassembled and assembled at any time.

Side edges of the connecting seats 44 are disposed with the plurality of connection structures 5, and the plurality of connection structures 5 comprise snapping positions 51 and buckling positions 52 (e.g., each of the plurality of connection structures 5 comprises a snapping position 51 and a buckling position 52). One of the snapping positions 51 on one of the plurality of pre-compressed springs 4 form a buckled connection with one of the buckling positions 52 on another of the plurality of pre-compressed springs 4. When the plurality of pre-compressed springs 4 are buckled to form the spring module 1 using the plurality of connection structures 5, the soft cushion layer 2 with a certain thickness is directly laid on a formed lying support surface of the spring module 1. The soft cushion layer 2 can be a whole cushion layer compositely molded or a combination of a plurality of cushion layers with different softness and hardness so as to form the soft cushion layer 2 with different hardness and tactility.
A plurality of straps 21 with pull buckles are disposed on the side edges around the soft cushion layer 2. The plurality of straps 21 with pull buckles form a detachable connection with corresponding ones of the connection structures 5 on corresponding ones of the plurality of pre-compressed springs 4. Corresponding ones of the plurality of pre-compressed springs 4 are located at an outer periphery of the spring module 1, and the soft cushion layer 2 is laid on an upper side of the spring module 1 to form a semi-enclosed form.
The plurality of connection structures 5 designed in this embodiment comprise the snapping positions 51 and the buckling positions 52, and the snapping positions 51 are configured to squeeze the buckling positions 52 to contract inward to release the buckled connection when being buckled in the buckling positions 52.
Specifically, the snapping positions 51 comprise elastic members 511 and snapping points 512 disposed on single sides of the elastic members 511, and the buckling positions 52 comprise U-shaped buckling grooves 521 and steps 522 disposed within the U-shaped buckling grooves 521. End surfaces of the steps 522 are configured to be buckled to the snapping points 512. Single guiding surfaces 523 obliquely extend from insertion openings of the U-shaped buckling grooves 521 to the steps 522 along an inserting direction of the snapping points 512, and the guiding surfaces 523 enable the snapping points 512 to contract inward to provide avoidance for insertion of the snapping positions 51. The elastic members 511 have deformation amounts for the snapping points 512 contracting inward to cooperate with the guiding surfaces 523 to form avoidance structures, or for the snapping points 512 being released from the steps 522.
During operation, the snapping positions 51 are inserted into the U-shaped buckling grooves 521 along the insertion direction, the snapping points 512 contract inward due to the guiding surfaces 523, and at the same time, the elastic members 511 contract inward to accumulate an elastic force. When the snapping points 512 are misaligned with the guiding surfaces 523 along the insertion direction, the snapping points 512 are inserted into the U-shaped buckling grooves 521 and are located on rear sides of the steps 522 along the insertion direction, and the snapping points 512 abut the steps 522 due to rebound resilience of the elastic members 511, so as to be positioned to form the buckled connections. When disassembly is required, the snapping points 512 on both sides of the plurality of connection structures 5 are merely pressed to contract inward to enable the snapping points 512 to be separated from abutting the steps 522 to release the buckled connection.
In this embodiment, the plurality of connection structures 5 comprise single protruding parts 513 and single concave parts 524 between the snapping positions 51 and the buckling positions 52 (e.g., each of the plurality of connection structures 5 comprises a protruding part 513 and a concave part 524 between a snapping position 51 and a buckling position 52). When the buckled connection is formed, one of the protruding parts 513 of the plurality of connection structures 5 on one of the plurality of pre-compressed springs 4 is inserted into one of the concave parts 524 on another of the plurality of pre-compressed springs 4 to form a plug-in connection, and stability of the buckled connection between two of the plurality of connection structures 5 can be increased.
In this embodiment, structures of the plurality of straps 21 with pull buckles of the soft cushion layer 2 configured to form detachable connection with the plurality of connection structures 5 are the same as the plurality of connection structures on the plurality of pre-compressed springs 4 to form an auxiliary buckled structure.
Referring to
Specifically, the snapping positions 51 comprise the elastic members 511 and the snapping points 512 disposed on the single sides of the elastic members 511, and the buckling positions 52 comprise the U-shaped buckling grooves 521 and the steps 522 disposed within the U-shaped buckling grooves 521. The end surfaces of the steps 522 are configured to be buckled to the snapping points 512. The guiding surfaces 523 obliquely extend from the insertion openings of the U-shaped buckling grooves 521 to the steps 522 along the inserting direction of the snapping points 512, and the guiding surfaces 523 enable the snapping points 512 to contract inward to provide avoidance for the insertion of the snapping positions 51. The elastic members 511 have the deformation amounts for the snapping points 512 contracting inward to cooperate with the guiding surfaces 523 to form the avoidance structures, or for the snapping points 512 being released from the steps 522.
In this embodiment, the plurality of connection structures 5 comprise the single protruding parts 513 and the single concave parts 524 between the snapping positions 51 and the buckling positions 52 (e.g., each of the plurality of connection structures 5 comprises the protruding part 513 and the concave part 524 between the snapping position 51 and the buckling position 52). When the buckled connection is formed, the one of the protruding parts 513 of the plurality of connection structures 5 on the one of the plurality of pre-compressed springs 4 is inserted into the one of the concave parts 524 on another of the plurality of pre-compressed springs 4 to form a plug-in connection, and the stability of the buckled connection between the two of the plurality of connection structures 5 can be increased. This embodiment differs from Embodiment 1 in that plug-in positioning members cooperate with the protruding parts 513 and the concave parts 524 are provided. The plug-in positioning members comprise positioning slots disposed on the protruding parts 513 and positioning posts disposed on the concave parts 524. There is a certain friction force between the positioning posts and the positioning slots, which provides a certain buckling force between the protruding parts 513 and the concave parts 524 during a plug-in connection, thereby buckling the protruding parts 513 and the concave parts 524 together. The buckling force can be automatically released from being buckled together by a slight external force.
In this embodiment, a structural design is provided in which the plurality of connection structures 5 are not disposed along edges of large end surfaces 41 of the plurality of pre-compressed springs 4. The plurality of connection structures 5 are not disposed on peripheries of the large end surfaces 41, but are disposed at positions below the large end surfaces 41 by at a certain distance.
The positions are not limited to the positions of the plurality of connection structures 5 shown in
In order to ensure that a non-rigid connection is formed between adjacent pre-compressed springs 4 of the plurality of pre-compressed springs 4, the plurality of connection structures 5 or the one or more third connecting members 6 can be made of elastic materials or flexible materials. The plurality of connection structures 5 are disposed at positions below the large end surfaces 41 to form a connection, enabling the large end surfaces 41 to form a free downward compressed deformation when the large end surfaces 41 are used as the lying supporting surface. The plurality of connection structures 5 are connected together to form a flexible connection. Even if the plurality of connection structures 5 have a downward compressed displacement when being pressed, the flexible connection can reduce a pulling interference force applied on the adjacent pre-compressed springs 4 of the plurality of pre-compressed springs 4 that are connected, thus ensuring elasticity independence of the plurality of pre-compressed springs 4 from each other.
Considering that the plurality of connection structures 5 are mainly to stabilize support of the large end surfaces 41 of the plurality of pre-compressed springs 4 to be more stable when the plurality of pre-compressed springs 4 are spliced to form the spring module 1 for use, and the plurality of pre-compressed springs 4 will not sway left and right relative to each other, resulting in a phenomenon of localized collapse. Therefore, when the positions of the plurality of connection structures 5 are arranged, it is optimal to arrange the plurality of connection structures 5 within upper position sections as no less than ⅓ of the plurality of pre-compressed springs 4 and adjacent to the large end surfaces 41. In doing so, interference between the plurality of pre-compression springs 4 caused by the plurality of connection structures 5 is reduced while ensuring stability of the connection.
It should be noted that, the positional arrangements of the plurality of connection structures 5 or the one or more third connecting members 6 in all embodiments are not limited to be disposed along the edges of the large end surfaces 41 and as described in Embodiment 2, but can be disposed within the upper position sections as no less than ⅓ of the plurality of pre-compressed springs 4 and adjacent to the large end surfaces 41.
Referring to
In this embodiment, the plurality of connection structures 5 are designed such that each of the snapping positions 51 comprises an elastic sheet 514 and a buckling block 515 disposed on a side of the elastic sheet 514, and each of the buckling positions 52 comprises a buckling hole 525. The buckling block 515 on one of the plurality of pre-compressed springs 4 forms a bucking connection with the buckling hole 525 on another of the plurality of pre-compressed springs 4. The elastic sheet 514 has a deformation amount for the buckling block 515 contracting inward to be buckled to the buckling hole 525 or to be released from the buckling hole 525.
At the same time, in order to increase a stability of the large end surfaces 41 used as the lying supporting surface and to ensure a stability of a connection of the plurality of connection structures 5 at the same time, each of the plurality of connection structures 5 comprises two protruding parts 526 located between a corresponding one of the snapping positions 51 and a corresponding one of the buckling positions 52. One of two protruding parts 526 comprises a concave cavity 516, and the concave cavity 516 is configured to receive another of the two protruding parts 526. Another of the two protruding parts 526 on one of the connecting seats 44 is plugged into the concave cavity 516 on another of the connecting seats 44, increasing a stability of the buckled connection between two of the plurality of connection structures 5.
In this embodiment, structures of the plurality of straps 21 with pull buckles of the soft cushion layer 2 configured to form detachable connection with the plurality of connection structures 5 are the same as the plurality of connection structures 5 on the plurality of pre-compressed springs 4 to form an auxiliary buckled structure.
Referring to
In this embodiment, the plurality of connection structures 5 are designed such that each of the snapping positions 51 comprises protrusions 517 with elastic sheets and opposite to each other. The protrusions 517 with the elastic sheets are disposed in an up-and-down direction. Each of the buckling positions 52 comprises slotted holes 527 corresponding to the protrusions 517 with the elastic sheets, and the protrusions 517 with the elastic sheets are buckled in the slotted holes 527 to form a buckled connection. There is a certain interval between two of the protrusions 517 with the elastic sheets, and the interval is used as a movement amount of the two of the protrusions 517 with the elastic sheets for contracting inward, so that the protrusions 517 with the elastic sheets contract inward to form a buckled connection with the slotted holes 527 or release the buckled connection with the slotted holes 527.
Each of the snapping positions 51 further comprises guiding rods 518 disposed on two sides of the protrusions 517 with the elastic sheets for alignment with the buckling positions 52 when the snapping positions 51 are buckled.
In this embodiment, structures of the plurality of straps 21 with pull buckles of the soft cushion layer 2 configured to form detachable connection with the plurality of connection structures 5 are the same as the plurality of connection structures 5 on the plurality of pre-compressed springs 4 to form an auxiliary buckled structure.
Referring to
In this embodiment, the plurality of connection structures 5 are designed such that each of the snapping positions 51 comprises elastic protrusions 519 opposite to each other. The elastic protrusions 519 are disposed in a left-and-right direction. Each of the buckling positions 52 comprises locking holes 528 corresponding to the elastic protrusions 519, and the elastic protrusions 519 are buckled in the locking holes 528 to form a buckled connection. There is a certain interval between two of the elastic protrusions 519, and the interval is used as a movement amount of the two of the elastic protrusions 519, so that the elastic protrusions 519 contract inward to form a buckled connection with the locking holes 528 or to release the buckled connection with the locking holes 528.
Two of the locking holes 528 of each of the buckling positions 52 are disposed on side edges of each of the buckling positions 52. A distance between the two of the locking holes 528 is less than a length of a cross-section of each of the buckling positions 52, and a distance between the two of the elastic protrusions 519 is matched with the length of the cross section of each of the buckling positions 52. The two of the elastic protrusions 519 are disposed in a corresponding one of the buckling positions 52 along an insertion direction, and hole positions of the two of the locking holes 528 are positioned at the two of the elastic protrusions 519 to achieve the buckled connection.
In this embodiment, structures of the plurality of straps 21 with pull buckles of the soft cushion layer 2 configured to form detachable connection with the plurality of connection structures 5 are the same as the plurality of connection structures 5 on the plurality of pre-compressed springs 4 to form an auxiliary buckled structure.
Referring to
Side edges of the connecting seats 44 are disposed with the plurality of connection structures 5, and one of the plurality of connection structures 5 on one of the plurality of pre-compressed springs 4 forms a buckled connection with one of the plurality of connection structures 5 on another of the plurality of pre-compressed springs 4 by one or more third connecting members 6. When the plurality of pre-compressed springs 4 are buckled to form the spring module 1 using the plurality of connection structures 5 and the one or more third connecting members 6, the soft cushion layer 2 with a certain thickness is directly laid on a formed lying supporting surface of the spring module 1. The soft cushion layer 2 can be a whole cushion layer compositely molded or a combination of a plurality of cushion layers with different softness and hardness so as to form the soft cushion layer 2 with different hardness and tactility.
A plurality of straps 21 with pull buckles are disposed on the side edges around the soft cushion layer 2. The plurality of straps 21 with pull buckles form a detachable connection with corresponding ones of the connection structures 5 on corresponding ones of the plurality of pre-compressed springs 4. Corresponding ones of the plurality of pre-compressed springs 4 are located at an outer periphery of the spring module 1, and the soft cushion layer 2 is laid on an upper side of the spring module 1 to form a semi-enclosed form.
The plurality of connection structures 5 of this embodiment comprise insertion holes 53 and snapping slots 54. The insertion holes 53 are in communication with the snapping slots 54, and widths of the snapping slots 54 are smaller than diameters of the insertion holes 53. The one or more third connecting members 6 comprise one or more rotating parts 61 and one or more protrusions 62 disposed on one or more end surfaces of the one or more rotating parts 61. One or more diameters of one or more end portions of the one or more protrusions 62 are matched with the insertion holes 53, and the one or more diameters of the one or more end portions of the one or more protrusions 62 are larger than the snapping slots 54. When the one or more end portions of the one or more protrusions 62 are disposed below the insertion holes 53 after passing through the insertion holes 53, the one or more protrusions 62 further slide into the snapping slots 54 to enable the one or more end portions of the one or more protrusions 62 to be buckled to bottoms of the snapping slots 54 for positioning.
In this embodiment, two adjacent pre-compressed springs 4 of the plurality of pre-compressed springs 4 are connected by the one or more third connecting members 6. Each of the one or more third connecting members 6 comprises four of the one or more protrusions 62, and four of the plurality of pre-compressed springs 4 are used as a group to form a buckled connection by one of the one or more third connecting members 6. When the one or more protrusions 62 are disposed in the insertion holes 53, the one or more third connecting members 6 enable the one or more rotating parts 61 to rotate so as to enable the one or more protrusions 62 to be disposed in the snapping slots 54 to form the buckled connection or to be disposed in the insertion holes 53 to release the buckled connection.
When the one or more rotating parts 61 drive the one or more protrusions 62 to be inserted into various ones of the insertion holes 53 on corresponding ones of the plurality of pre-compressed springs 4, the one or more rotating parts 61 rotate counterclockwise to drive the one or more protrusions 62 to slide into the snapping slots 54, so that the snapping slots 54 and the one or more protrusions 62 form the buckled connection. The one or more rotating parts 61 then rotate clockwise to drive the one or more protrusions 62 to slide into the insertion holes 53 to release the buckled connection.
In this embodiment, structures of the plurality of straps 21 with pull buckles of the soft cushion layer 2 configured to form detachable connection with the plurality of connection structures 5 are the same as the one or more third connecting members 6, and the one or more third connecting members 6 on the plurality of straps 21 with pull buckles comprise protrusions 62 to form an auxiliary buckled structure.

Each of the one or more third connecting members 6 comprises two elastic snapping ends 66 and a connecting part 67 connected to the two elastic snapping ends 66. The connecting part 67 has elastic deformation amounts for the two elastic snapping ends 66 to move away from each other. The two elastic snapping ends 66 are squeezed to contract inward to release the buckled connection when the two elastic snapping ends 66 are buckled in the snapping slots 54. A length of the connecting part 67 of each of the one or more third connecting members 6 can be used to adjust a gap between the pairs of the plurality of pre-compressed springs 4 within a certain range, adjusting a footprint of the spring module 1 within a small range, so that an area of the spring module 1 has a certain small adjustable amount.

In this embodiment, the spring module 1 is formed by a buckled connection of the plurality of pre-compressed springs 4 housing the forward tapered springs 48a and the plurality of pre-compressed springs 4 housing the inverted tapered springs 48b. The plurality of pre-compressed springs 4 define a connection but not a rigid connection. Within the formed spring module 1, there is no interference from other connections between two adjacent pre-compressed springs 4 of the plurality of pre-compressed springs 4 to ensure left and right pre-compressed springs 4 of the plurality of pre-compressed springs 4 to have independent compression movement when being stressed. Elastic variations caused by stress applied to individual pre-compressed springs 4 of the plurality of pre-compressed springs 4 only occur on upper and lower pressure surfaces, without traction and interference from elastic variation of other springs in left and right directions.
In this embodiment, a pad 22 can be optionally placed on the lying supporting surface of the formed spring module 1, followed by a soft cushion layer 2, or the soft cushion layer 2 with a certain thickness can be directly placed. The soft cushion layer 2 and the pad 22 can be a whole cushion layer compositely molded or a combination of a plurality of cushion layers with different softness and hardness to form the soft cushion layer 2 and the pad 22 having different hardness and tactility.
The soft cushion layer 2 can be laid on an upper side or on the upper side and around the spring module 1 to form enclosed or semi-enclosed forms without covering a bottom surface of the connecting base 7. In this embodiment, the connecting base 7 comprises the plurality of connection structures 5 that form a buckled connection with a plurality of straps 21 with pull buckles around the soft cushion layer 2.
