[0001] Cross-references to related applications
[0002] This application claims priority to and is based on Chinese Patent Application No. 2024110526036, filed with the China National Intellectual Property Administration on August 1, 2024, entitled "A Spring Module and its Release Method, and an Elastic Pad", the contents of which are incorporated herein by reference. Technical Field
[0003] This invention relates to the field of furniture, and more particularly to spring modules and elastic pads. Background Technology
[0004] In modern life, mattresses are an indispensable piece of bedding. Especially with increasing life pressures, resilient mattresses with elastic components are becoming increasingly popular for relaxation during sleep. Most existing resilient mattresses use individually pocketed springs, each spring packaged in its own pocket, arranged in a pattern, and then covered by a single piece of foam rubber to form the mattress. This type of mattress cannot be disassembled and is difficult to transport. Therefore, mattresses with removable springs have been developed. However, during handling and transportation, the removed springs remain in a released state, taking up considerable space and manpower for transport.
[0005] In order to save manpower and space, springs that can be locked in a compressed state have been developed. However, currently, springs that can be locked in a compressed state need to be compressed and released individually, which is time-consuming, laborious and inconvenient. Summary of the Invention

[0065] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.
[0066] Example 1
[0067] Referring to Figures 1-5, this embodiment provides a spring module, including multiple elastic units arranged in an array. Each elastic unit includes a spring 1, with a base 2 at the bottom and a top cover 3 at the top. The elastic unit also includes an intermediate connecting strip 4, which connects the base 2 and the top cover 3. In this embodiment, the intermediate connecting strip is rigid, and adjacent spring top covers can be connected.
[0068] The upper cover 3 is provided with a channel 31 extending along the length of the intermediate connecting strip 4, so that the upper cover 3 has translational freedom relative to the intermediate connecting strip 4 in the direction closer to the base 2; in order to fix the spring 1 in the compressed position, a snap-fit member 41 is provided on the intermediate connecting strip 4; when the spring 1 is in the released state, the snap-fit member 41 is located outside the upper cover 3 and on the bottom side of the upper cover 3; when the spring 1 is in the compressed state, the upper cover 3 and the snap-fit member 41 move relative to each other, so that the snap-fit member 41 is placed in the channel 31 and is limited and engaged with the channel 31 in the direction of the release of the spring 1.
[0069] In other words, when the spring 1 is in the released state, the latch 41 will not enter the channel 31 of the upper cover 3. However, when the spring 1 is compressed, the latch 41 will be placed in the channel 31 and the limit will be achieved through interference fit.
[0070] In this embodiment, to achieve the above-mentioned limiting fit, the snap-fit member 41 is disposed on the side wall of the intermediate connecting strip 4 and extends outward along the radial direction of the intermediate connecting strip 4; when the spring 1 is in a compressed state, the snap-fit member 41 is placed inside the channel 31 and has an interference fit with the inner wall of the channel 31.
[0071] To achieve pre-tensioning of the spring 1 by the intermediate connecting strip 4, a raised edge 42 extends radially outward from the top of the intermediate connecting strip 4. The width of the raised edge 42 is greater than the width of the channel 31, so as to limit the engagement between the intermediate connecting strip 4 and the upper cover 3 in a direction away from the base 2. In this way, by adjusting the length of the intermediate connecting strip 4, the distance between the upper cover 3 and the base 2 can be changed, thereby keeping the spring 1 in a pre-tensioned state.
[0072] To secure the intermediate connecting strip 4 and the base 2, the bottom of the intermediate connecting strip 4 protrudes radially outward to form an inverted conical insertion part; the base 2 has an insertion hole that mates with the insertion part.
[0073] This embodiment also provides a method for releasing the spring module as described above. An external force is used to pull the upper cover 3 so that the locking member 41 and the channel 31 of the upper cover 3 are released from their limiting engagement, releasing one spring 1 of the spring module. Adjacent springs 1 are released one after another under the action of the restoring force of the spring 1, so that the whole row or the whole group of springs 1 are released into an elastic state.
[0074] Example 2
[0075] Referring to Figures 6-8, this embodiment provides a spring module, including multiple elastic units arranged in an array. Each elastic unit includes a spring, with a base 2 at the bottom and a top cover 3 at the top. It also includes an intermediate connecting strip 4, which connects the base 2 and the top cover 3. The intermediate connecting strip 4 can provide a preload force to the spring located between the base 2 and the top cover 3 by connecting the base 2 and the top cover 3. In this embodiment, the intermediate connecting strip is flexible.
[0076] In order to fix the spring in the compressed position, this embodiment also includes a fastener 5, which is located at the upper end of the entire row of springs, and a pressure cap 51 is provided on each spring corresponding to the fastener 5;
[0077] The pressure cap 51 and the upper cover 3 are provided with channels 511 and 31 that run through the middle connecting strip 4 at corresponding positions, so that the pressure cap 51 and the upper cover 3 have translational freedom relative to the middle connecting strip 4 in the direction closer to the base 2. In this way, the pressure cap 51 can be pressed to move the pressure cap 51 and the upper cover 3 downward, thereby compressing the spring. Furthermore, the width of the channel 511 on the pressure cap 51 is smaller than the width of the channel 31 on the upper cover 3. This is to avoid the channel 511 on the pressure cap 51 blocking the channel 31 on the upper cover 3, which would affect the fixation of the spring in the compression position.
[0078] In this embodiment, the intermediate connecting strip 4 is provided with two intermittently arranged snap fasteners 41. The intermediate connecting strip 4 and the snap fasteners 41 are usually made of plastic and can be integrally formed. The pressure channel 511 or 31 can squeeze the protrusion of the snap fastener. After passing through the channel 511, the snap fastener returns to its original shape, and the cover 51 or the top cover 3 is locked on the snap fastener 41. When the spring is in the released state, the snap fastener 41 is located outside the top cover 3 and at the bottom side of the top cover 3. When the spring is in the compressed state, the snap fastener 41 is placed on the upper and lower sides of the channel 31 of the cover 51 and is limited and engaged with the channel 31 along the direction of spring release.
[0079] In other words, when the spring is in a released state, the latching member 41 will not enter the channel 511 of the pressure cap 51. However, when the spring is compressed, the latching member 41 will partially pass through the channel 511 and be positioned on the upper and lower sides of the channel 511 to achieve a limiting position. To achieve this structure, the side wall of the channel 511 of the pressure cap 51 is provided with an opening 512 communicating with the channel 511, and the width of the opening 512 gradually increases along the direction away from the channel 511 to form a clearance opening. The latching member 41 consists of two limiting protrusions located on the side wall of the intermediate connecting band 4 and extending in the direction away from the intermediate connecting band 4. When the spring is compressed, the lower limiting protrusion passes through the channel 31 of the pressure cap 51 through the clearance opening, and the intermediate connecting band 4 between the two limiting protrusions enters the channel 31 of the pressure cap 51 through the opening 512. This ensures that after the spring is compressed, the two limiting protrusions are located on the upper and lower sides of the channel 31 of the pressure cap 51, respectively.
[0080] To achieve pre-tensioning of the spring by the intermediate connecting strap 4, a raised edge 42 extends radially outward from the top of the intermediate connecting strap 4. The width of the raised edge 42 is greater than the width of the channel 31, so as to limit the engagement between the intermediate connecting strap 4 and the upper cover 3 in a direction away from the base 2. In this way, by adjusting the length of the intermediate connecting strap 4, the distance between the upper cover 3 and the base 2 can be changed, thereby keeping the spring in a pre-tensioned state.
[0081] To secure the intermediate connecting strip 4 and the base 2, the bottom of the intermediate connecting strip 4 protrudes radially outward to form an inverted conical insertion part 43; the base 2 has an insertion hole that mates with the insertion part 43.
[0082] This embodiment also provides a method for releasing the spring module as described above. An external force is used to pull the fastener 5 so that the locking member 41 and the channel 31 of the pressure cover 51 are released from their limiting engagement, releasing one spring of the spring module. Adjacent springs are released one after another under the action of the spring's restoring force, so that the entire row or group of springs are released into an elastic state.
[0083] Example 3
[0084] Referring to Figures 9-11, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, there is only one spring 1 in the elastic unit, while in this embodiment, the spring 1 is divided into a first sub-spring and a second sub-spring, as well as a waist ring 13 connecting the first sub-spring and the second sub-spring. The waist ring 13 is provided with a clearance opening 131 for the intermediate connecting belt 4 to pass through.
[0085] Example 4
[0086] Referring to Figure 12, the difference between this embodiment and embodiment 2 is that the pressure cap is removed, and the structure as in embodiment 2 is directly set in the channel 31 of the upper cover 3. The spring 11 is fixed in the compressed position by the cooperation between the channel 31 of the upper cover 3 and the snap-fit 41.
[0087] Example 5
[0088] Referring to Figure 13, the difference between this embodiment and embodiment 4 is that the spring 1 is divided into a first sub-spring 11 and a second sub-spring 12, and a waist ring 13 connecting the first sub-spring 11 and the second sub-spring 12. The waist ring 13 is provided with a clearance opening 131 for the intermediate connecting belt 4 to pass through.
[0089] Example 6
[0090] Referring to Figure 14, the difference between this embodiment and embodiment 5 is that the design of two springs 1 is eliminated, but the waist ring 13 set in the middle of the spring 1 is retained. The waist ring 13 is provided with a clearance opening 131 for the intermediate connecting belt 4 to pass through.
[0091] Example 7
[0092] Referring to Figure 15, the difference between this embodiment and Embodiment 6 is that: the intermediate connecting band 4 is provided with second locking members 44 spaced apart, and the locking members 41 and 44 are respectively located on the upper and lower sides of the waist ring; when the spring 1 is in a compressed state, the locking members 44 are placed on the upper and lower sides of the insertion hole of the base 2, and are limited and engaged with the insertion hole along the direction of spring 1 release. In this way, the stability of the elastic unit fixed in the compressed state can be increased by the two locking members 41 and 44. And the intermediate connecting band 4 is fixed on the waist ring 13.
[0093] Example 8
[0094] Referring to Figure 16, the difference between this embodiment and embodiment 4 is that: there are multiple intermediate connecting strips 4, and the tops of the multiple intermediate connecting strips 4 are connected together by the protruding edge 42.
[0095] Example 9
[0096] Referring to Figures 17-18, the difference between this embodiment and Embodiment 4 is that an additional top spring 14 is added to the structure of Embodiment 4, while the original spring 1 becomes the bottom spring. The height of the top spring 14 is less than the height of the bottom spring, so that the top spring does not need to be compressed during storage; only the bottom spring needs to be compressed. The structure for compressing and releasing the bottom spring is the same as in Embodiment 4, and will not be described again.
[0097] This embodiment also provides an elastic pad, including a soft pad and an elastic module as described in any of embodiments 1-9.
[0098] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
