Spring connecting member, elastic module, and elastic cushion

Abstract

The elastic module includes a plurality of pre-compressed springs (1), which are in contact with or adjacent to each other, with the pre-compressed springs (1) not connected at their upper ends, and with connecting members provided at the middle portions of the pre-compressed springs (1), connecting adjacent pre-compressed springs (1) at their middle portions. The connecting members have an appropriate height, allowing the springs to bend laterally. Because the upper ends of the pre-compressed springs (1) in the spring module are free to move and are not subjected to traction, the upper ends of the springs are compressed independently, and adjacent uncompressed springs are not separated from adjacent compressed springs by the traction of the connecting members. No gaps are created at the boundaries, and the entire spring module is tightly packed.

[0003] This application is based on and further claims priority from a Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 14, 2023, bearing application number 202311720553X and titled "Spring connecting member, elastic module and elastic cushion," the contents of which are hereby incorporated by reference into the present specification.

[0004] The present invention relates to a connection arrangement for pre-compressed springs and elastic modules connected by said arrangement. [Background technology]

[0005] Conventional spring-based elastic cushions exhibit elasticity that functions as a single unit, meaning that when pressure is applied to a specific area, the surrounding springs are also subjected to pressure. While such elastic cushions can withstand large loads, they are unable to achieve the elastic response to changes in the body's posture when used in spring-type beds. This is due to the spring mounting structure in the elastic cushion. Although the springs provide elasticity as separate units, in elastic cushions, the upper ends of the springs are usually connected, so the entire spring is subjected to pressure as a single unit. Therefore, it is extremely important for the springs to function independently and not separate from each other in order for the elastic cushion to deform and respond to changes in the body's posture. Summary of the Invention

[0006] The present invention can provide an elastic cushion that deforms in response to changes in pressure, and in such an elastic cushion, the boundary between the compressed spring and the non-compressed spring is not pushed apart.

[0007] The elastic module of the present invention includes a plurality of pre-compressed springs, the pre-compressed springs being in contact with or close to each other, the upper ends of the pre-compressed springs not being connected, and connecting members being provided in the middle portions of the pre-compressed springs, and the pre-compressed springs in the front and rear rows being connected at the middle portions of their sides, or adjacent pre-compressed springs being connected at their middle portions by the connecting members.

[0008] The connecting member has an appropriate height, preferably 0.5 mm or more, or the height of the connecting member exceeds the diameter of the spring wire, so that the connecting member can bend the spring laterally.

[0009] The spring may be pre-compressed and covered with a flexible sheath such as a fabric cover, a net cover, or may be tensioned at both ends with woven belts. The spring is hourglass-shaped, i.e., the diameter of the upper and lower ends of the spring is larger than the diameter of the middle part.

[0010] The springs may be two types of springs with different diameters, with a first constricted spring and a second bulged spring alternately arranged.

[0011] The connecting member is a peripheral ring located intermediate the flexible sheath, and may be an annular band or spaced bands made of plastic or other material. The connecting member is quadrilateral and is attached to the waist of the pre-compressed springs, with adjacent pre-compressed springs connected at the corners of the quadrilateral of the connecting member.

[0012] Adjacent pre-compression springs are connected at their intermediate portions, specifically, by connecting members that engage with each other or by a third member that bridges between two connecting members.

[0013] The bottom of the spring of the elastic module is connected to a bottom plate or flexible material.

[0014] The present invention further provides an elastic module including a plurality of pre-compressed springs arranged in contact or close proximity, wherein a connecting member is provided at the middle portion of the pre-compressed springs, adjacent pre-compressed springs are connected by the connecting member, and the connection configurations on each side of the connecting member of the pre-compressed springs are identical.

[0015] The connecting member includes a connection base on which an insertion mechanism and a receiving mechanism are provided, and the insertion mechanism and the receiving mechanism are installed on the same side of the pre-compressed spring as a connecting configuration, and the pre-compressed springs are connected by connecting the insertion mechanism of the pre-compressed spring with the receiving mechanism on either side of another pre-compressed spring.

[0016] The present invention further provides an elastic module including a plurality of pre-compressed springs arranged in contact or close proximity, wherein a connecting member is provided at an intermediate portion of the pre-compressed springs, adjacent pre-compressed springs are connected by the connecting member, and the connecting arrangements on each side of the connecting member of the pre-compressed springs include a first connecting arrangement and a second connecting arrangement that are installed adjacent to each other.

[0017] The connection member includes a connection base, on which a plug is provided as a first connection configuration and a socket is provided as a second connection configuration, and the pre-compression springs are connected by a male-female connection between the plug of the pre-compression spring and the plug of another pre-compression spring.

[0018] The present invention further provides an elastic module including a plurality of pre-compressed springs arranged in contact or close proximity, wherein a connecting member is provided at the middle portion of the pre-compressed springs, adjacent pre-compressed springs are connected by the connecting member, the connecting member is divided into a first connecting member and a second connecting member, the first connecting member and the second connecting member are respectively provided at the waist portions of different pre-compressed springs, and the first connecting member of one pre-compressed spring is connected to the second connecting member of another pre-compressed spring, thereby connecting the pre-compressed springs.

[0019] The present invention further provides an elastic module including a plurality of pre-compressed springs arranged in contact or close proximity, wherein connecting members are provided at intermediate portions of the pre-compressed springs, and the elastic module further includes a bridge member that connects the connecting members to connect adjacent pre-compressed springs.

[0020] The elastic cushion includes one or more of the elastic modules, and the elastic modules are joined together or the outer periphery of the elastic modules is surrounded by a woven belt.

[0021] The pre-compressed springs of the spring module of the present invention are connected at their middles, allowing their upper ends to move freely and not be subjected to traction, so that the upper ends of the springs are compressed independently, preventing adjacent uncompressed springs from separating from adjacent compressed springs due to the traction of the connecting members, preventing gaps from forming at the boundaries and ensuring a tight fit throughout the spring module.The connecting members provided by the present invention have an appropriate height, allowing the springs to bend laterally and expand in response to compression, resulting in a simple configuration of the connecting members and convenient connection.

[0023] The technical aspects of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is clear that the described embodiments are preferred embodiments of the present invention and should not be considered as excluding other embodiments. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without requiring creative work fall within the scope of protection of the present invention.

[0024] In the claims, specification and drawings of the present invention, unless otherwise specified, terms indicating directions such as "height," "top," "top," "bottom," "inside," "outside," "upper," "lower," "front," and "rear" are based on the directions and positional relationships shown in the drawings, and are merely intended to facilitate and simplify the description of the present invention, and do not expressly or imply that devices or components have a specific direction or must be configured or operated in a specific direction, and therefore should not be construed as limiting the specific protection scope of the present invention.

[0025] Example 1 As shown in Figures 1 and 2, the pre-compressed spring 1 includes a spring 1.1 and a fabric cover 1.2. The spring 1.1 is covered by the fabric cover 1.2. A knot is formed by squeezing the end of the fabric cover 1.2 containing the spring 1.1, and the end 1.3 of the knot enters a hole in the spring's squeezing coil or top cover. The connecting member includes a connection base 2, a protruding snap 3, and a recessed snap 4. The connection base 2 is attached to the lower part of the pre-compressed spring 1 and has insertion grooves 2.1 on at least two opposing sides. The protruding snap 3 is fixed to the front end of the insertion groove 2.1. The recessed snap 4 is fixed to the rear end of the insertion groove 2.1 and has two spaced-apart latches 3.1. One of the latches 3.1 is hollow, with a cantilever arm 3.2 on one side wall. The latch 3.1 is provided with a position limiting structure 3.3 and a base 3.4 at its end. The recessed snap 4 is provided with two engagement holes 4.1 that fit the latches 3.1.

[0026] As shown in Figures 3, 4 and 5, the pre-compressed springs 1 are connected to each other by attaching a connecting member to the waist of each pre-compressed spring 1, arranging the pre-compressed springs 1 in an alternating fashion, and inserting the protruding snaps 3 of the connecting member of the pre-compressed spring in the rear row into the engaging openings of the recessed snaps 4 of the pre-compressed spring in the front row, thereby connecting the front and rear row springs. By pressing the bases 3 and 4 of the protruding snaps 4, the recessed snaps 4 can be released, and the pre-compressed springs can be released from the connection.

[0027] The connection base 2, the protruding snap 3, and the recessed snap 4 of the connection member may be integrated or connected as separate parts. The separate structure has the advantage that different materials and different strengths can be selected.

[0028] <Example 2> 6, 7 and 8, the pre-compressed spring 1 of Example 2 is similar to Example 1 in that the connecting member includes a connecting base 2, a protrusion 5 and a groove 6. The connecting base is quadrilateral, with two protrusions 5 fixed to two adjacent corners of the quadrilateral connecting base and two grooves 6 fixed to the other two corners of the quadrilateral connecting base.

[0029] To connect the pre-compressed springs 1, as shown in Figure 8, a connecting member is attached to the waist of each pre-compressed spring 1, and the pre-compressed springs 1 in the front and rear rows are arranged alternately. The protrusions 5 of the connecting member of the pre-compressed spring in the rear row are inserted into the grooves 6 of the pre-compressed springs in the front row, thereby connecting the front and rear rows of springs. By locating the grooves 6 and protrusions 5 at different heights, the connecting members can be positioned at the same horizontal height after connection. In this embodiment, the protrusions 5 are T-shaped and the grooves are straight. The T-shaped protrusions 5 are inserted into the grooves 6 from above without any positioning restriction structure, achieving a stable connection using gravity alone.

[0030] Example 3 As shown in Figures 9, 10, and 11, the pre-compressed spring 1 of Example 3, like Example 1, has a connecting member including a connecting base 2 and a snap 8. The connecting base 2 is provided at the waist of the pre-compressed spring 1 and has insertion grooves 2.1 on at least two opposing side surfaces. The snap 8 is fixed at its front end within the insertion groove 2.1 of the connecting base and has latches 8.1 arranged above and below the front end, and the latches 8.1 are elastic. The snap has an engagement hole 8.2 at its rear end, or the snap 8 is fixed to the insertion groove 2.1. Even in this case, there is a space at the rear end of the insertion groove 2.1 of the connecting member for the latch to be inserted.

[0031] Regarding the connection between the pre-compressed springs 1, as shown in Figure 11, a connecting member is attached to the waist portion of each pre-compressed spring 1, and the pre-compressed springs 1 in the front and rear rows are arranged alternately, and the snaps 8 of the connecting members of the pre-compressed springs in the rear row are inserted into the insertion grooves 2.1 of the connection bases of the pre-compressed springs in the front row or the engagement holes 8.2 at the rear of the snaps 8, thereby connecting the front and rear row springs.

[0032] Example 4 As shown in FIG. 12, the feature of this embodiment is that the pre-compressed springs are connected by two connecting members 10 arranged one above the other, which is suitable for large springs with a height of more than 30 cm.

[0033] <Example 5> As shown in Figures 13, 14, and 15, the connecting member 10 of this embodiment connects multiple pre-compressed springs 1. The connecting member 10 includes two pieces 10.1 and 10.2, but may include three or four pieces. Multiple springs 1 are engaged with the connecting member 10 at corresponding positions, thereby connecting the multiple pre-compressed springs at their waists. The connecting member 10 may also have an irregular shape.

[0034] Example 6 As shown in Figures 16, 17 and 18, the connecting member 10 of this embodiment connects multiple pre-compressed springs 1. The connecting member 10 includes two pieces 10.1 and 10.2, and the springs 1 are engaged at corresponding positions of the connecting member 10, thereby connecting multiple pre-compressed springs at their waists. The pre-compressed springs are aligned so as to align with each other.

[0035] Example 7 19, 20, 21, and 22, the pre-compressed spring 1 of this embodiment, like the first embodiment, includes a connection base 2 as a connecting member, and the four sides of the connection base 2 are provided with identical connecting structures 11. The connecting structure 11 includes a receiving mechanism and an insertion mechanism, with the insertion mechanism being a protrusion 11.1 and the receiving mechanism being a groove 11.2. The protrusion 11.1 is elastic in a plane perpendicular to the insertion direction, and a release member 11.5 is provided on the wall of the receiving groove 11.2 to push up the elastic member, thereby enabling the protrusion 11.1 and the receiving groove 11.2 to be locked and unlocked.

[0036] More specifically, the groove 11.2 is provided on the same side of the protrusion 11.1. One side of the protrusion 11.1 is a cantilever arm 11.3, which has a notch at its front end as a position limiting feature 11.4. A release member 11.5 is provided in the groove wall at the end that engages with the cantilever arm 11.3, and a protrusion block for locking the position limiting feature 11.4 is provided on the groove wall. The pre-compressed spring 1 is connected by positioning and fitting the position limiting feature 11.4 into the protrusion block of the groove 11.2. The pre-compressed spring 1 is removed by pressing the release member, releasing the position limiting feature 11.4 of the cantilever arm 11.3 from its positioning and fitting with the protrusion block. Because the connection features 11 of the connection base in this embodiment are completely identical, the connection feature 11 of one pre-compressed spring can be inserted and connected to the connection feature 11 on either side of another pre-compressed spring, without the need to identify the insertion direction.

[0037] Example 8 23, 24, 25 and 26, the main difference between this embodiment and embodiment 7 is that the release member 12.5 is connected to the cantilever arm 12.3 on one side of the protrusion, the position limiting arrangement 12.4 is a protrusion block of the cantilever arm 12.3, and the groove 12.2 is provided with a space for locking the position limiting arrangement 12.4. As other points are the same as those of embodiment 7, a description thereof will be omitted.

[0038] Example 9 As shown in Figures 27, 28, 29, 30, and 31, the pre-compression spring 1 of this embodiment, like the first embodiment, has a connecting member including a connecting base 2 and an insert plug 13. The insert plug has a latch 13.1 at its front end and an engagement hole 13.2 at its rear end. The latch 13.1 has a cantilever arm 13.3, and a release member 13.5 is attached to the cantilever arm 13.3. The latch 13.1 is provided with a position limiting structure 13.4 that engages with the engagement hole 13.2. Insertion grooves 14 are provided on four side surfaces of the connecting base 2, and the insert plugs 13 are inserted into the insertion grooves 14 on two opposing side surfaces of the connecting base. After being inserted into the insertion grooves 14, the insert plugs 13 protrude from the front end of the insertion grooves 14. The engagement hole 13.2 is located at the rear end of the insertion groove 14.

[0039] In this embodiment, the insertion plugs 13 are fixed to two opposing side surfaces of the connection base 2 by grooves 14. When connecting the pre-compressed springs 1, the pre-compressed springs 1 in the front and rear rows are arranged alternately, and the latches 13.1 of the connecting members of the pre-compressed springs in the rear row are inserted into the engagement holes 13.2 of the pre-compressed springs in the front row, thereby connecting the pre-compressed springs in the front and rear rows. After connection is complete, the insertion grooves 14 on the other two sides of each row of pre-compressed springs 1, where the insertion plugs are not inserted, abut against each other. When removing the pre-compressed springs 1, the release members 13.5 are pressed, and the position limiting structures 13.4 of the latches 13.1 release the positioning engagement with the engagement holes 13.2, thereby removing the pre-compressed springs 1 in the front and rear rows.

[0040] In this embodiment, in order to ensure aesthetics and further fix the pre-compressed springs 1 in the outermost edge row, edge connecting members 15 are inserted into the two insertion grooves 14 that abut each other in the outermost edge row, thereby further fixing the pre-compressed springs 1 in the outermost edge row.

[0041] Example 10 As shown in Figures 32, 33, 34, and 35, in the pre-compression spring 1 of this embodiment, similar to the first embodiment, the connecting member includes a connection base 2. The plug protrusion 16 and the socket groove 17 are respectively provided on two opposing side surfaces of the connection base 2, and protrusions 16 and grooves 17 are respectively provided on two other opposing side surfaces. A protrusion block 16.1 is provided above the protrusion 16 as a position limiting structure, and a space is provided on the upper wall of the groove for the protrusion block 16.1 to fit into. By fitting the protrusion block 16.1 into the space, the protrusion 16 and the groove 17 can be positioned and fitted together.

[0042] The protrusion block 16.1 is elastic, and a release member 17.1 for pushing up the protrusion block 16.1 is provided at a position on the upper wall of the groove corresponding to the protrusion block 16.1. By pushing the release member 17.1, the protrusion block 16.1 is released from the space in the upper wall of the groove, and the positioning engagement between the protrusion 16 and the groove 17 is released.

[0043] When connecting a pre-compressed spring 1, the protrusion 16 of the connecting member of the pre-compressed spring 1 is inserted into the groove 17 of another pre-compressed spring 1, and the protrusion block 16.1 fits into the space in the upper wall of the groove, thereby connecting the pre-compressed spring 1. When removing the pre-compressed spring 1, the release member 17.1 is pressed, and the protrusion block 16.1 moves out of the space in the upper wall of the groove, thereby releasing the positioning engagement between the groove 17 and the protrusion 16, and the pre-compressed spring 1 is removed.

[0044] Example 11 As shown in Figures 36, 37, 38, 39 and 40, the main difference between this embodiment and embodiment 10 is that in this embodiment, the connecting member includes four detachable pieces 18.1, 18.2, 18.3 and 18.4, which are engaged with each other and engaged with the waist portion of the pre-compressed spring 1. After engagement, protrusions 16 are provided on two opposing side surfaces of the connecting base 2, and grooves 17 are provided on two other opposing side surfaces of the connecting base 2. As the rest is the same as embodiment 10, a description thereof will be omitted.

[0045] Example 12 As shown in Figures 41, 42, 43, and 44, the main difference between this embodiment and Example 10 is that the protrusion 19 and groove 20 are removably connected to the connection base 2, the connection member is divided into two pieces 21.1 and 21.2, and the two pieces are engaged and connected to the waist portion of the pre-compressed spring 1 by the protrusion 19. After engagement, the protrusions 19 are installed on two opposing side surfaces of the connection base 2, and the grooves 20 are installed on two other opposing side surfaces of the connection base 2. Protrusion blocks 19.1 are installed on both sides of the protrusion 19 as position limiting structures, and release members 20.1 are installed on both side walls of the groove 20 at positions corresponding to the protrusion blocks 19.1. The release members 20.1 and both side walls of the groove 20 form spaces into which the protrusion blocks 19.1 can be inserted, thereby enabling the position limiting structures and the groove 20 to be positioned and fitted. Other aspects of this embodiment are similar to Example 10, so a description thereof will be omitted.

[0046] Example 13 45, 46, 47, 48, 49, and 50, the pre-compressed spring 1 of this embodiment is similar to that of the first embodiment in that the connecting member includes a connection base 2 and T-shaped protrusions 22, with the four T-shaped protrusions 22 fixed around the periphery of the connection base 2, and the connecting member being divided into two detachable pieces 23.1 and 23.2 that are engaged with the waist portions of the pre-compressed springs 1. The T-shaped protrusions 22 of different pre-compressed springs 1 are bridged and connected by a bridge member 24.

[0047] In this embodiment, the bridge member 24 includes a fixed base 24.1 and a knob 24.2 connected to the periphery of the fixed base 24.1. The knob 24.2 is provided with a groove 24.3 into which the T-shaped protrusion 22 fits, and the knob 24.2 is rotatable around the groove 24.3, with the T-shaped protrusion 22 and the groove 24.3 positioned and fitted together horizontally. When connecting the pre-compressed spring 1, the T-shaped protrusion 22 is fitted into the groove 24.3, and the knob 24.2 is rotated until it is vertically positioned and fitted with the T-shaped protrusion.
