Fig. 6 A to Fig. 6 C shows deformation state of the spring structure body 11 ' shown in Fig. 4 when being compressed in its telescopic direction.
Fig. 6 A shows the un-compressed state of spring structure body 11 ', and Fig. 6 B shows the slightly compressed state of spring structure body 11 ', figure
6C shows the substantially compressed state of spring structure body 11 '.As shown in Fig. 6 B and Fig. 6 C, spring structure body 11 ' is in its flexible side
When being compressed in (axial direction), preferential than the part other than this substantially position in the part of the spiral helicine groove 12a ' of foams 12 '
It moves (deformation), partial dislocation (deformation) degree of spiral helicine protrusion 12b ' is lower.Its reason is by inference: due to foam
The diameter of the part of the groove 12a ' of body 12 ' is less than the diameter of the part (part of protrusion 12b ') other than groove, and only
The part of protrusion 12b ' is provided with the lines of helical spring 13 ', therefore the spring constant of the part of groove 12a ' is less than recessed
The spring constant of part (part of protrusion 12b ') other than slot.As a result, in spring structure body 12 ' in axial stretching
When, it can prevent the lines of helical spring 13 ' from biting foams 12 ', and can be effectively prevented due to this bite and send out
The breakage of raw foams 12 '.When using Fig. 2 and spring structure body 11 shown in Fig. 3, it is also possible to obtain same movement is made
Use effect.
Fig. 7 shows 12 or 12 ' entirety of foams from compression stress to spring structure body and helical spring when applying
13 or 13 ' movement.In the following, to foams 12 or 12 ' entirety and helical spring 13 in present embodiment or its variation pattern
Or 13 ' spring constant and recovery time be illustrated.Foams 12 or 12 ' in present embodiment or its variation pattern
It is whole in telescopic direction from the recovery time of compressive state (per unit distance) be set as than helical spring 13 or 13 ' from
The recovery time (per unit distance) of compressive state is long.As noted previously, as helical spring 13 or 13 ' is embedded in foams 12
Either 12 ' is interior or be fixed on its surface, therefore, as shown in fig. 7, when compression stress F1 is applied to spring structure body, spiral bullet
The compressed height of spring 13 or 13 ' is identical as foams 12 or 12 ' compressed height.The material of foams 12 or 12 '
Characteristic and style characteristic are set as, and when discharging compression stress F1 in this case, helical spring 13 or 13 ' returns to pressure earlier
Home position H0 before contracting.More specifically, the physical property of foams 12 or 12 ' is set as, per unit in compressed distance PL
The recovery time of distance is longer than the recovery time of helical spring 13 or 13 '.Compression shape of this condition in foams 12 or 12 '
Elastic restoring force (=spring constant) under state and helical spring 13 or 13 ' compressive state under the equal feelings of elastic restoring force
It is similarly set up under condition.
On the other hand, the elastic restoring force under the compressive state in the telescopic direction (axial direction) of foams 12 or 12' entirety
(spring constant) is less than the elastic restoring force (spring constant) under the compressive state in the telescopic direction of helical spring 13 or 13'.
Specifically, foams 12 or 12 ' and helical spring 13 or 13 ' material property and style characteristic be set as, foams 12 or
12 ' whole spring constants are equal to or less than the spring constant of helical spring 13 or 13 '.That is, foams 12 or 12 ' and spiral
Spring 13 or 13 ' setting meet following condition.
Recovery time: helical spring < foams
Spring constant: foams≤helical spring
It sets in this way, helical spring 13 or 13 ' can be flexible by foams 12 or 12 ' tripping spring structural body
The vibration in direction (axial direction).For this purpose, the relaxation time of damping vibration shortens, while longitudinally rocking reduction, lateral wobble also subtracts
It is small.
As spring structure body, to being only made of helical spring in the case where (be considered as pocketed coil) and such as this implementation
Vibration in the case where foam surface fixed helical spring of the variation pattern of mode has carried out comparative experiments.Fig. 8 is shown
Device in this comparative experiments is constituted.As shown, it is produced on the sample pad 80 that internal arrangement configures multiple spring structure bodies, and
Make to fall the exacerbation position P in this sample pad 80 with height of fall h as the spherical counterweight 81 for turning over dummy.Further,
The counterweight 82 of cuboid is configured as the dummy slept on one side in measuring point, and with accelerometer and measures its movement.To matching
(the spiral bullet for being equipped with the spring structure body being only made of helical spring and being constituted in the fixed helical spring in the surface of foams
Spring+foams) sample pad 80 of spring structure body carried out comparative experiments respectively.
Fig. 9 A and Fig. 9 B show the result of this comparative experiments.Fig. 9 A shows the vibration measurement of horizontal direction as a result, Fig. 9 B shows
The vibration measurement result of vertical direction out.In these figures, horizontal axis indicates the time, and the longitudinal axis indicates acceleration.Dotted line table is used in figure
" the only helical spring " shown indicates the data for there was only the spring structure body of helical spring, " helical spring+foam indicated by the solid line
Body " indicates the data that the spring structure body of helical spring is buried in the foams for being formed with helicla flute.It can be seen that regardless of
It is in vertical direction or in the horizontal direction, to be fixed with the spring structure body and only spiral of helical spring on the surface of foams
The case where spring, is compared, and die-away time shortens.By adjusting the combination of the physical property of the physical property and helical spring of foams, when decaying
Between can become shorter.It follows that according to the spring structure body for burying helical spring in the foams for being formed with helicla flute,
The relaxation time that damping vibration terminates can be shortened to, the longitudinal swag phenomenon of inhibition and lateral wobble phenomenon are contributed.It is steeping
The case where surface fixation helical spring of foam body, can similarly shorten to the relaxation time that damping vibration terminates, can be to inhibition
Longitudinal swag phenomenon and lateral wobble phenomenon are contributed.
