Description

A compressible spring module, an elastic module, and an elastic pad Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a spring module and its release method, and an elastic pad. Background Technology

[0002] In modern life, mattresses are an indispensable piece of bedding. Especially with increasing life pressures, elastic mattresses with internal elastic components are becoming increasingly popular for relaxation during sleep. Most existing elastic mattresses use individually pocketed elastic units, each 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 elastic units have been developed. However, during handling and transportation, the removed elastic units remain in a released state, taking up considerable space and manpower for transport.

[0003] In order to save manpower and space, elastic units that can be locked in a compressed state have emerged. However, currently, elastic units that can be locked in a compressed state need to be compressed and released individually, which is time-consuming, labor-intensive and inconvenient.

[0004] Utility Model Content

[0005] This invention provides a compressible spring module, an elastic module, and an elastic pad, wherein the elastic units do not need to be released individually, reducing the number of releases and improving release efficiency and safety.

[0006] To solve the above-mentioned technical problems, this utility model provides a compressible spring module, including multiple elastic units and a third fastener. The third fastener connects the multiple elastic units in a row. The compressible spring module switches between a compressed state and a released state under the action of external force. The third fastener has a plug corresponding to each elastic unit on its side facing the elastic unit. The upper end cap of the elastic unit has an opening surface for inserting the plug. At least two elastic locking members extend from the edge of the opening surface in a downward axial direction. The elastic locking members have elasticity that expands outward in a radial direction. The lower end cap of the elastic unit has a cavity.

[0007] In the compressed state, the elastic locking member is inserted into the cavity and expands radially outward under the action of the plug until the elastic locking member abuts against the cavity; in the released state, the plug leaves the elastic locking member, and the elastic locking member releases its contact with the cavity.

[0008] In some embodiments, the elastic locking member includes a connecting end and a free end, the connecting end being connected to the upper end cover, and the free end being suspended so that the elastic locking member has the elasticity to expand outward along the radial direction.

[0009] In some embodiments, the inner side of the free end protrudes inward to form a guide portion, which gradually widens in the axial downward direction, such that the inner side of the guide portion forms a guide slope.

[0010] In some embodiments, the outer surface of the lower end of the plug tapers inward in a downward axial direction, so that the outer side of the lower end of the plug forms a slope that engages with the guide slope of the guide portion.

[0011] In some embodiments, the top of the cavity extends toward the center to form an extension, and the elastic locking member abuts against the extension under the action of the plug.

[0012] In some embodiments, the extension gradually widens in a downward axial direction, such that a guide slope is formed on the inner side of the extension.

[0013] In some embodiments, the outer surface of the free end tapers inward in a downward axial direction, such that the outer side of the free end forms a slope that engages with the guide slope of the extension.

[0014] To solve the above-mentioned technical problems, this utility model also provides an elastic module, including multiple compressible spring modules as described above, and a base plate, wherein the elastic unit is mounted on the base plate.

[0015] In some embodiments, the insertion cavity extends axially downwards and protrudes from the lower end cap to form a protrusion, and the base plate is provided with grooves corresponding to the protrusions, and the protrusions are inserted into the grooves.

[0016] In some embodiments, grooves are provided on both sides of the groove, the grooves including a wide portion and a narrow portion, the width of the groove gradually narrowing from the wide portion to the narrow portion.

[0017] In some embodiments, symmetrically arranged feet corresponding to the grooves are provided on both sides of the protrusion, and the swivel feet are limited and engaged with the narrow portion along the axial direction.

[0018] In some embodiments, the swivel foot includes a connecting post, the bottom of which extends radially outward to form a limiting portion. The swivel foot is inserted from the wide portion of the groove and then swivels to the narrow portion, with the limiting portion engaging with the narrow portion in an axial direction.

[0019] This utility model also provides an elastic pad, including the above-mentioned elastic module.

[0020] Compared to existing technologies, this invention features a third fastener with plugs corresponding to the elastic units. The plugs compress and lock the elastic units by pressing the elastic locking components against the insertion cavity. To release the compression, simply pull the third fastener to remove one plug, and the elastic unit will be released. Furthermore, the restoring force of the released elastic unit will pull out the adjacent plugs of the third fastener, thus releasing the compression lock of each elastic unit individually. This eliminates the need for each elastic unit to be released individually, reducing the number of releases and improving release efficiency and safety. Attached Figure Description

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 utility model can be understood according to the specific circumstances.

[0049] This embodiment provides an elastic module, including multiple compressible spring modules and a base plate 2. The compressible spring modules are mounted on the base plate 2 in an array. The elastic unit 1 includes a spring and an upper cover and a lower cover placed at the upper and lower ends of the spring.

[0050] The compressible spring module includes multiple elastic units 1 and a third fastener 3. The third fastener 3 connects the multiple elastic units 1 in a row. The compressible spring module switches between a compressed state and a released state under the action of external force. The third fastener 3 has a plug 31 corresponding to each elastic unit 1 on the side facing the elastic unit 1. The upper end cover of the elastic unit 1 has an opening surface 14 for inserting the plug 31. The edge of the opening surface 14 extends at least two elastic locking members 11 in a downward axial direction. The elastic locking members 11 have elasticity that expands outward in a radial direction. The lower end cover of the elastic unit 1 has a cavity 12.

[0051] In the compressed state, the elastic locking member 11 is inserted into the insertion cavity 12 and expands radially outward under the action of the plug 31 until the elastic locking member 11 abuts against the insertion cavity 12; in the released state, the plug 31 leaves the elastic locking member 11, and the elastic locking member 11 is released from abutment with the insertion cavity 12.

[0052] Specifically, in this embodiment, the elastic locking member 11 includes a connecting end 111 and a free end 112. The connecting end 111 is connected to the upper end cap, and the free end 112 is suspended, thereby giving the elastic locking member 11 the elasticity to expand radially outward. The top end of the insertion cavity 12 extends towards the center to form an extension 121. Under the action of the plug 31, the free end 112 of the elastic locking member 11 expands radially outward, thereby abutting against the extension 121 of the insertion cavity 12. Under the compression of the plug 31, the frictional force between the elastic locking member 11 and the extension 121 is greater than the restoring force of the elastic unit 1, thereby locking the elastic unit 1 in a compressed state.

[0053] More specifically, the insertion cavity 12 extends axially downwards, protruding from the lower end cover to form a protrusion 122. The base plate 2 has grooves 21 corresponding to the protrusions 122, and the protrusions 122 are inserted into the grooves 21. Slide grooves 22 are provided on both sides of the grooves 21, each groove 22 including a wide portion and a narrow portion, with the width of the groove 22 gradually narrowing from the wide portion to the narrow portion. Rotating feet 13, corresponding to the slide grooves 22, are symmetrically arranged on both sides of the protrusions 122. Each rotating foot 13 includes a 131, the bottom of which extends radially outwards to form a limiting portion 132. After being inserted into the wide portion of the slide groove 22, the rotating foot 13 is rotated to the narrow portion, and the limiting portion 132 and the narrow portion are axially limited and engaged.

[0054] During assembly, the user aligns the screw foot 13 with the wide part of the slide groove 22, and then inserts the protrusion 122 of the elastic unit 1 into the groove 21. At this time, the screw foot 13 is inserted into the wide part of the slide groove 22. Then, the elastic unit 1 is rotated until the screw foot 13 and the narrow part of the slide groove 22 are matched in the axial direction, thus realizing the installation of the elastic unit 1 and the base plate 2.

[0055] When a user needs to move or store an unused mattress, external force is used to insert each plug 31 of the third fastener 3 into the opening 14 of each elastic unit 1, thereby driving the elastic locking member 11 into the insertion cavity 12. The elastic locking member 11 expands radially outward to abut against the insertion cavity 12, thus compressing the spring modules in a row into a locked state. Repeating the above steps completes the compression and locking of the entire elastic module, saving space during transportation and storage.

[0056] When the user needs to use the mattress, they use external force to pull open the third fastener 3 of one group of spring modules in the elastic module. The plug 31 is pulled out from the opening 14 of the elastic unit 1. At the same time, the free end 112 of the elastic locking member 11 retracts radially, thereby releasing the contact between the elastic locking member 11 and the extension 121 of the insertion cavity 12. The elastic unit 1 is then released from the compressed and locked state. Adjacent elastic units 1 can be released successively under the restoring force of the elastic unit 1, so that the entire row of elastic units 1 is released. By repeatedly pulling the third fastener 3 of each group of spring modules, each elastic unit 1 of the elastic module can be released. There is no need to release them one by one by hand, which improves the efficiency of release. By laying a padding layer on the upper layer of the elastic module of this embodiment, an elastic mattress can be formed.

[0057] To save the user's external force when compressing the elastic unit 1 and to facilitate the user's compression and release of the elastic unit 1, in this embodiment, the inner side of the free end 112 protrudes inward to form a guide portion 1121. The guide portion 1121 gradually widens in the axial downward direction, so that the inner side of the guide portion 1121 forms a guide slope. The outer side of the lower end of the plug 31 contracts inward in the axial downward direction, so that the outer side of the lower end of the plug 31 forms a slope that guides and cooperates with the guide slope of the guide portion 1121. With the above configuration, due to the cooperation of the two slopes of the guide portion 1121 and the outer side of the plug 31, the plug 31 can push the free end 112 of the elastic locking member 11 more effortlessly and accurately.

[0058] Meanwhile, in this embodiment, the extension 121 gradually widens in the axial downward direction, forming a guide slope on the inner side of the extension 121. The outer side of the free end 112 contracts inward in the axial downward direction, forming a slope on the outer side of the free end 112 that guides and engages with the guide slope of the extension 121. Through the guiding engagement of the slope on the outer side of the free end 112 and the guide slope on the inner side of the extension 121, the elastic locking member 11 can be inserted into the insertion cavity 12 more easily. The user will need less effort when compressing the elastic unit 1. At the same time, the guiding engagement between the plug 31 and the elastic locking member 11 also makes it easier to pull out the plug 31, and the elastic unit 1 is released more smoothly.

[0059] In this embodiment, the compressible spring module is mounted on the base plate 2. Of course, as a simple alternative to this embodiment, the compressible spring module does not necessarily have to be mounted on the base plate 2. It can also be compressed and released independently, which can also save space for transportation and storage.

[0060] Under the action of external force, each plug 31 in the third fastener 3 is inserted into the opening surface 14 of each elastic unit 1, and the elastic locking member 11 is driven to be inserted into the cavity 12. The elastic locking member 11 expands outward along the radial direction and abuts against the cavity 12, so that the spring modules are compressed in a row and locked.

[0061] During unlocking, pulling the third fastener 3 causes one of its plugs 31 to be pulled out from the opening 14 of the elastic unit 1. Simultaneously, the elastic end of the elastic locking member 11 contracts radially, releasing the contact between the elastic locking member 11 and the extension 121 of the insertion cavity 12. The elastic unit 1 then releases from its compressed and locked state. Adjacent elastic units 1 can then be released successively under the restoring force of the elastic unit 1, resulting in the entire row of elastic units 1 being released into an elastic state. This allows the entire row of compressible spring modules to be released simply by pulling the third fastener 3, causing one plug 31 to be pulled out from the opening 14, eliminating the need for manual release and improving efficiency.

[0062] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model. Industrial applicability

[0063] This invention utilizes a third fastener with plugs corresponding to the elastic units. The elastic units are compressed and locked by the plugs pressing against the elastic locking components and the insertion cavity. To release the compression, simply pull the third fastener to remove one of the plugs. Furthermore, the restoring force of the released elastic unit will pull out adjacent plugs of the third fastener, thus releasing the compression lock of each elastic unit individually. This eliminates the need for individual release of each elastic unit, reducing the number of releases, improving release efficiency and safety, and demonstrating good industrial applicability.
