Description

Spring structure connection body, mattress and chair

FIELD OF THE INVENTION The present invention relates to a spring structure coupling body that can be used mainly as a cushion for a bed mattress or a chair such as a sofa.

BACKGROUND OF THE INVENTION In order to obtain a moderate cushioning property in a seat of a mattress or a sofa, a spring pressure of a coil spring is used. As the utilization form of the spring pressure, it can be roughly divided into the following methods: a so-called bonnell coil method in which a plurality of juxtaposed coil springs are connected by a metal wire, and each coil spring is individually accommodated in the coil spring. A so-called independent tube spring method that functions independently in a cylindrical bag body made of non-woven fabric or the like.

In a tandem spring mattress, since the coil springs are connected to each other, they have stability as a whole cushioning body, but it is easy to propagate the vibration of the coil springs through the connection structure. That is, it is pointed out that there is a problem that because adjacent coil springs are tied together throughout the entire area of the mattress, if a person sleeping on one side of the bed turns over, it will cause vibration caused by deformation of the turning spring. It spreads in the horizontal direction, so that the person sleeping beside is shaken in the horizontal direction (the so-called rolling phenomenon) and easily wakes up.

On the other hand, in the mattress of the independent tube spring method, since each coil spring functions independently, it has the advantage that compared with the series spring method, the vibration of the coil spring can be suppressed from being transmitted to the adjacent coil spring. Roll. However, since the coil springs are not connected to each other, in exchange for the advantage of rolling, the stability of the coil spring made of a plurality of coil springs as a cushioning body is low, and deformation in the mattress is easy to occur. . Therefore, as shown in FIG. 13, the following method is performed: the entire upper surface of the group of independent coil springs P is fixed with a cover sheet S such as a felt having a thickness to ensure that it is composed of a plurality of independent coil springs. The stability of the buffer. Also, as shown in FIG. 14, the bag bodies 4 containing the coil springs 3 are connected to each other in a row to form a so-called independent tube spring row L to improve the stability so that the independent tube springs do not become scattered. .

SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, the structure for improving the stability of the buffer body composed of the spring structure of the independent tube spring method as described above may sometimes function as a vibration propagation medium. That is, since the covering sheet S disposed on the upper surface of the independent tube spring group shown in FIG. 13 causes vibration to propagate in the plane direction, the independent tube spring row L shown in FIG. 14 transmits vibration in the direction of the connected rows. It can't effectively suppress the occurrence of roll. In addition, the spring structure in this specification means a structure including a coil spring, and of course, an independent tube spring is included, and a coil spring is also included.

As described above, although there is a difference in degree between the independent tube spring method and the tandem spring method, there is still room for improvement in the suppression of the propagation of vibration with respect to a spring structure using a spring pressure.

The present invention has been made in view of such a situation, and an object thereof is to provide a coil spring that functions independently, while maintaining a moderate cushioning property and suppressing the occurrence of rolling caused by the propagation of vibration. In addition, the connection structure of the spring structure that contributes to the improvement of the usability of a mattress or a sofa, that is, the connection structure of the spring structure.
Means to solve the problem

In order to solve the above-mentioned problems, the inventor of the present case devoted himself to the results of the review, focusing on the mechanism of roll generation in the structure for ensuring the stability of the spring structure in a mattress using a coil spring type spring structure, However, the following situation was found: To reduce roll, it is effective to interrupt or reduce the vibration of the spring structure (up and down direction) to transmit the vibration to the surface direction (horizontal direction and horizontal direction) of the mattress. .

Specifically, as shown in FIG. 13, since each spring structure (independent tube spring P) is connected to the upper surface with a covering sheet S such as a felt, as shown in FIG. 15, if the user A is turned over, etc. When the spring structure A on one end of the mattress is compressed by the action (vertical displacement va, horizontal displacement ha = 0), the uncompressed part of the spring structure B will be compressed in the direction in which the spring structure A is compressed. Stretch and tilt (vertical displacement vb, horizontal displacement hb), but when the spring structure A is restored by releasing the load, the inclination of the spring structure B will also be restored, and it will be linked to the expansion and contraction direction of the subsequent spring structure A The spring structure B causes the spring structure B to swing in the horizontal direction on the side of the user B by performing a horizontal swing motion of the lower end support. In addition, since the tilt of the spring structure C toward the horizontal direction (vertical displacement vc, horizontal displacement hc) is enlarged as it moves away from one end side of the user A's movement such as turning over, the user at the other end The B side makes the roll more pronounced. In addition, since the spring structure A having released the load performs damping vibration while dissipating energy in the telescopic direction, the period (relaxation time) until the end of the damping vibration continues to roll. Therefore, it is possible to reduce rolling by interrupting or reducing the transmission of the vibration of the spring structure in the horizontal direction to the horizontal direction. Based on this knowledge and insight, the present invention has finally been completed.

In order to solve the above-mentioned problem, the spring structure coupling body of the present invention is arranged in a planar area by aligning a plurality of coil springs so that their expansion and contraction directions become up and down, and adjacent coil springs in at least a part of the planar area are mutually adjacent to each other.

Further, it is also preferable that the telescopic member constituting the above-mentioned connection member is a member having rubber elasticity or spring elasticity, and a spring constant in a tensile direction is smaller than a spring constant in a telescopic direction of the coil spring. The use of a rubber elastic or spring elastic telescopic member having a spring constant in the tensile direction which is smaller than that in the expansion and contraction directions of the coil spring as a connecting member can reduce vibration appropriately, and each coil spring does not become In a scattered situation, a spring structure coupling body having a sense of stability can be obtained.

It is also preferable that the spring constant in the tensile direction of the telescopic member constituting the above-mentioned connecting member is larger than the spring constant in the horizontal direction of the coil spring.

In this way, a spring structure connecting body having a sense of stability and an independent cushioning property of each coil spring can be obtained.

Moreover, it is also preferable that the connection part of the spring structure connection body of the present invention which is connected by a telescopic member or a flexible member is an end portion in the telescopic direction of the coil spring. By using the portion where the displacement caused by the expansion and contraction of the coil spring is large as the connection portion, a spring structure connection body having excellent independent cushioning properties and spring stability of each coil spring and capable of appropriately reducing vibration can be obtained.

Moreover, it is also preferable that the connection part of the spring structure connection body of the present invention which is connected by the telescopic member or the flexible member is a side surface portion of the coil spring in a direction orthogonal to the telescopic direction. Since the side surface portion of the coil spring is used as a connection portion, vibration can be appropriately reduced, and each coil spring is connected by the side portion, so that a spring structure connection body having spring stability and independent cushioning properties can be obtained.

The form for implementing the invention is shown in FIG. 1. The spring structure connecting body 1 according to the first embodiment of the present invention is roughly composed of a spring structure 2 and a connecting member 5. The spring structure 2 is formed by a coil spring 3 and The bag body 4 in which the bag body 4 is housed is formed, and the coupling member 5 is used to connect the plurality of coil spring structures 2. In addition, the spring structure coupling body 1 can be arranged in the mattress frame 8 to form a mattress. The term “up and down” as used in this specification refers to the up and down direction (thickness direction) in a state where a mattress or the like provided with the spring structure connecting body 1 is used, that is, the Z direction in FIG. 1 and the configuration of the spring structure The expansion and contraction directions of the coil springs 3 of the connection body 1 are the same. In this specification, the term "left and right" refers to a mattress surface direction in a state where a mattress or the like provided with the spring structure connecting body 1 is used, that is, the XY direction and the horizontal direction in FIG. 1.

First, the connecting member 5 constituting the spring structure connecting body 1 of the present embodiment will be described. The overall structure of the connecting member 5 of this embodiment is shown in FIG. In this embodiment, the connecting member 5 is composed of a plurality of ring-shaped members 5b and a connecting portion 5a connecting them, and an outer peripheral portion where the ring-shaped members 5b aligned on the same plane are in contact with each other is used as the connecting portion. 5a are connected. The ring-shaped member 5 b is a stretchable member having an elasticity, the ring-shaped inner diameter is formed to be equal to or smaller than the outer diameter of the spring structure 2, and the ring-shaped member 5 b is configured to be attachable along the outer peripheral side surface 2 b of the spring structure 2. The minimum unit of the spring structure coupling body 1 is shown in FIG. 2. As shown in FIG. 2, the connecting member 5 of this embodiment has a figure-eight structure as a minimum unit. The figure-eight structure is a ring-shaped member 5 b formed into a shape such as a thick rubber band, and the outer peripheral portion is connected. The parts 5a are connected. In actual use, it is configured to have a number of ring members 5b arranged in the plane direction corresponding to the number of spring structures 2 to be connected, and to have adjacent ring members 5b connected to each other in a ring-shaped outer peripheral portion.部 5a. 5a.

The connecting member 5 according to the present embodiment may be formed of at least a part of a material or structure having elasticity, and it is preferable to form the entire connecting member 5 as an elastic member. Examples of the elastic material or structure include a synthetic resin material, a rubber material, and a spring structure. Among them, from the viewpoint of ensuring the independent cushioning property of the spring structure 2 and excellent interruption in the left-right direction (plane direction) with respect to the vibration in the telescopic direction, the telescopic member is preferably a spring constant in the tensile direction in the actual shape. A member having rubber elasticity or spring elasticity that is smaller than the spring constant in the expansion and contraction direction of the coil spring. In the case where a spring structure to which a spring coil has been conventionally used is described as an example, the spring constant of the connecting member 5 should be 1 N / mm or less, preferably 0.5 N / mm or less, and more preferably 0.3 N. / mm or less. In addition, this spring constant is measured using a tensile tester, and a sample piece with a length of 100 mm (excluding the grip portion of the jig) is stretched at a stretching speed of 100 mm / min at a room temperature of 25 ° C. On the other hand, when the length is 30 mm, the elongation length of the sample piece is a value calculated in a range of 10 mm to 20 mm. In this embodiment, a styrene-based elastomer material having a Young's modulus of 650 kPa is selected as a stretchable member, particularly from the viewpoint of excellent moldability and lightness.

In addition, from the viewpoint of improving the stability of the spring structure coupling body 1, it is preferable that the telescopic member connecting the spring structure body 2 has a spring constant in the tensile direction in the actual shape, rather than a cantilever which has fixed the lower end of the coil spring 3. When the upper end is pushed down horizontally, the coil spring 3 has a larger spring constant and is a member having rubber elasticity or spring elasticity.

As shown in FIG. 2 and FIG. 7 (a) in detail, the spring structure 2 according to the present embodiment is composed of a coil spring 3 that expands and contracts in the up-down direction and a bag body 4 that houses the coil spring 3. As shown in FIG. 1, the spring structure coupling body 1 of this embodiment can be inserted into each ring of the above-mentioned coupling member 5 in the vertical direction by inserting each spring structure body 2 up and down along the side peripheral surface 2 b of the spring structure body 2. It is obtained by disposing the ring-shaped member 5b of the connection member 5. Although the ring-shaped member 5b can be detachably fixed to a side peripheral surface of a predetermined position of the spring structure 2 due to its elasticity, it can also be fixed in part by an adhesive, a stapler, or the like. In this way, by adjoining the adjacent spring structures 2 with the connecting member 5, independent cushioning and stability of the spring structures 2 can be achieved, and vibrations in the expansion and contraction directions of the adjacent spring structures 2 can be interrupted or reduced. The situation is conveyed to the left and right (plane direction).

Since the spring structure coupling body 1 of the present invention connects the spring structure body 2 with the coupling member 5, it is easy to exert the independent cushioning function of the spring structure body 2 and is also excellent in stability as the spring structure coupling body 1. In addition, the vibration caused by the expansion and contraction of the spring structure 2 on one side when the user rolls over can be attenuated or absorbed by the connection member 5 to reduce the transmission of the vibration to the spring structure 2 on the other side. As shown in FIG. 3 (a), when the spring structure 2 on one side has contracted, the connection portion 5a or the ring-shaped member 5b of the connection member 5 to which both are connected is extended to prevent the other side from being stretched. In the case where the spring structure 2 is stretched in a direction in which the spring structure 2 is compressed, it is inclined. 3 (b) and 3 (c) are explanatory diagrams showing an arrangement pattern and an effect of the mattress in the spring structure connecting body 1 according to this embodiment. In FIG. 3 (b), the spring structure coupling body 1 is arrange | positioned in the whole mattress, and all the spring structure bodies 2 are connected by the connection member 5. At this time, if the user A turns over on the mattress, although the spring structure 2 supporting the user A is compressed, the spring structure 2 disposed between the user A and the user B is used by the present invention. Since the connecting member 5 is connected, the spring structure 2 supporting the user B is prevented from being tilted while being stretched in the direction in which the spring structure 2 is compressed. In addition, as shown in FIG. 3 (c), the spring structure connecting body 1 may be disposed not only on the entire mattress but on a part of the mattress, for example, only in a region between the user A and the user B. Although the spring structure 2 in FIG. 3 (c) has a region bonded by a non-stretchable or non-flexible sheet H, the regions bonded by the hard sheet H are bound to each other. Since the connecting member 5 of the invention is connected, it is possible to prevent the spring structure 2 supporting the user B from being tilted and stretched in a direction in which the spring structure 2 is compressed by the action of the user A. In this way, according to the spring structure coupling body 1 of the present invention, it is possible to interrupt or reduce the situation where the vibration generated by the spring structure body 2 is transmitted to the left-right direction (plane direction). By this action, a spring structure connecting body can be obtained which can reduce the roll caused by the movement of the user on one side and improve the comfort of sleeping and the comfort of sitting up.

In FIGS. 1 to 3, although the connection member 5 is disposed at one center portion in the vertical direction of the side peripheral surface 2 b of the spring structure 2, as shown in FIG. 4, a plurality of connection members 5 may be disposed. Specifically, as shown in FIG. 4, two connecting members 5 can be used to respectively connect a plurality of adjacent spring structures 2, an upper portion, and a lower portion. Thereby, the stability of the spring structure coupling body 1 is improved.

As described above, although the connecting member 5 according to the present embodiment is made of a stretchable material as a whole, the connecting member 5 is made of a stretchable material, but a part of the connecting member 5 may be made of a stretchable member within a range that does not hinder the effect of the present invention. , And the other parts are formed as non-telescoping members. For example, the ring-shaped member 5b of the connection member 5 is a telescopic member, and the connection portion 5a is a non-stretchable member, or the ring-shaped member 5b of the connection member 5 is a non-stretchable member, and the connection portion 5a is provided. For telescopic members and so on. Furthermore, it is preferable that the application portion of the telescopic member in the connection member 5 is the spring structure 2 side (the bag body 4 side).

FIG. 5 shows another example of the spring structure coupling body of the present embodiment. The spring structure 2 shown in FIG. 5 is formed by connecting the bag body 40 accommodating the coil spring 3 with a welding portion 40 a to form an independent tube spring row 2L. As shown in FIG. 5, the spring structure 2 having such a unit structure is formed by separating the upper side of the bag body 40 between the adjacent spring structures 2 to form a cut-off portion 40 b and connecting the connecting member 5 A connecting portion 5 a fitted into the connecting member 5 is located at the cutting portion 40 b, and a spring structure connecting body 1 is obtained.

In addition, another configuration example of the connection member 5 is shown in FIG. 6. The connecting member 5 may be a member that connects a plurality of cylindrical members 5c as shown in FIG. 6 (a) with a connecting portion 5a provided on the peripheral side surface thereof, or a plurality of members as shown in FIG. 6 (b). The lid-like member 5d is connected to each other by a connecting portion 5a provided on a side surface of the lid. 6 is a diagram showing the minimum unit of the spring structure coupling body 1 in the same manner as in FIG. 2. In actual use, it is configured to have a number equivalent to the number of the spring structure bodies 2 to be connected. The cylindrical member 5c or the lid-shaped member 5d arranged in the plane direction has a connecting portion 5a that connects the adjacent cylindrical members 5c or the lid-shaped member 5d to each other at their peripheral sides. In FIG. 6 (a), although three spring members 5 are used to connect the spring structure 2, the number of the spring members 2 used may be one or two, and is not limited thereto. Moreover, the cylinder length (length in the up-down direction) of the cylindrical member 5c can be appropriately changed, and it can also be set to be substantially the same as the length in the up-down direction in a state where no pressure is applied to the spring structure 2. In addition, in FIG. 6 (b), the spring structure 2 is connected by covering the upper and lower ends of the spring structure 2 by using two connection members 5 constituted by a cover-like member 5d. The number of the connecting members 5 may be one, and for example, only the upper end of the spring structure 2 may be used. Further, the spring structure 2 may be connected by combining a plurality of the connecting members 5 including the ring-shaped member 5b, the cylindrical member 5c, and the cover-like member 5d. Although the entire connecting member 5 shown in FIG. 6 may be a telescopic member as a whole, a part of the connecting member 5 may be a telescopic member within a range that does not impede the function and effect of the present invention. Some are constructed as non-stretchable members. However, since the application portion of the telescopic member in the connection member 5 is preferably the spring structure 2 side (the bag body 4 side), specifically, the following method can be cited: the cylindrical member 5c or the cover of the connection member 5 The shape member 5d is a telescopic member, and the connection part 5a is a non-telescopic member.

In addition, although the bag body 4 constituting the spring structure 2 uses a non-stretchable sheet material in a general independent tube spring, it may be a fabric made of a stretchable knitted fabric or a stretchable material. , Non-woven fabric or sheet. Since the bag body 4 can be formed of a flexible material, and the bag body 4 and the connecting member 5 can be expanded and contracted in accordance with the up-and-down movement of the spring structure body 2, the expansion and contraction of the spring structure 2 can be further reduced A case where the vibration in the direction is transmitted in the left-right direction (plane direction).

In addition, the spring structure 2 may include the coil spring 3 and the bag body 4 as shown in FIG. 7 (a), and may also be inserted by the coil spring 3 and the coil as shown in FIG. 7 (b). The spring 3 has a cylindrical foam body 9 inside a spiral structure, and a bag body 4 that houses these. Since the spring structure 2 can be provided with such a structure, the vibration in the expansion-contraction direction of the spring structure 2 can be braked, so that the roll prevention effect can be further enhanced.
