  • leg pad As the material for the leg pad used in sample 1 a and sample 2 a , a material that shows the best result is used among many materials the inventor studied and tested. (the leg pad will be described in detail, later).
  • FIGS. 4 and 5 are analyzed as follows.
  • leg pad is designed the most properly.
  • the leg pad is designed the most properly for effective vibration attenuation. Therefore, it is preferable that, first of all, the most suitable leg pad, particularly, the most suitable material of the leg pad is used for attenuation of the vibration, and the other vibration attenuation parameters are taken into consideration. According to this, the inventor studied on the leg pad suitable for vibration attenuation further, to obtain the following results.
  • the leg pad has an excellent vibration attenuating characteristic.
  • the leg pad actually, it is required to meet, not only the vibration attenuating characteristic, but also other various conditions.
  • conditions such as mechanical properties, such as hardness, anti-slip property for preventing the washing machine from slipping from an installed place, formability representing easiness of fabrication, and the like are required to be satisfied. Because, even if the vibration attenuation characteristic is satisfied, if the material fails to have a proper hardness, resonance is occurred at a certain range of rotation speed of the washing machine, to cause walking of the washing machine. If friction with the floor is not adequate, it is liable that the washing machine slips on the floor.
  • leg pad At the end, even though it is required that the leg pad meets above different conditions in addition to the vibration attenuating characteristic, selection of an optimal leg pad that meets above conditions substantially has been difficult in the related art. Accordingly, up to now, as the leg pad, metal, plastic, isobutylene-isoprene rubber, or the like is used, each of the material has advantages, and disadvantages. Even though metal or plastic, with a comparatively high hardness, has a resonance range outside of rotation speed of the washing machine, it is liable that the leg pad of metal or plastic causes walking of washing machine in almost all ranges of the rotation speed, regardless of the rotation range.
  • the leg pad of metal or plastic is liable to cause slipping of the washing machine because the metal or plastic has low friction with the floor on which the washing machine is installed.
  • the butyl rubber since the butyl rubber has a resonance range in a low rotation speed range of the washing machine, it is required that the washing machine is controlled to pass the resonance range quickly, and the leg pad of the butyl rubber is liable to cause walking of the washing machine in the low rotation speed range, even though the walking is comparatively rare in a high rotation speed range.
  • the leg pad is preferably formed of a copolymer in which the hard blocks HS and the soft blocks SS make a net form. Because the use of the leg pad of the copolymer of the hard blocks HS and the soft blocks SS enables to select a material that meets required mechanical properties, such as hardness, as the hard blocks, and a material that meets required vibration attenuation characteristic as the soft blocks. According to this, the leg pad can be designed comparatively easily, that meets the vibration attenuation characteristics while other conditions are met.
  • a material that has a glass transition is used as the block copolymer, particularly, the soft block, and more preferably, a material of which glass transition temperature is close to a temperature of use of the washing machine. Because, though thermal movement of chain form of polymers in the net becomes violent at a temperature higher than the glass transition temperature, to exhibit a rubbery state, the thermal movement is suppressed at a temperature below the glass transition temperature, to become a glassy state due to reduction of its own volume, and have a poor vibration attenuation effect.
  • amorphous polymers such as rubber
  • rubber is selected as the leg pad.
  • the butyl rubber used presently also exhibits the glass transition.
  • the leg pad is required to meet, not only the vibration attenuation characteristic, but also other properties, different from the block copolymer of the hard blocks and the soft blocks of the present invention, the butyl rubber, a copolymer prepared by copolymerizing a small amount of isoprene with isobutylen, can not meet other properties besides the vibration attenuation characteristic.
  • the butyl rubber has a glass transition temperature in a range of ⁇ 40° C. ⁇ 60° C., which is substantially low than the temperature of use of the washing machine.
  • the butyl rubber has a uniform damping force in a temperature range of use of the washing machine substantially, in an actual temperature range of use of the washing machine, the damping force of the leg pad of the butyl rubber is poorer than the leg pad of the block copolymer of the present invention.
  • the leg pad of the present invention is formed of a block copolymer of hard blocks and soft blocks, wherein the hard blocks are selected in mechanical point of view, and the soft blocks are selected in view of vibration attenuation.
  • a material is selected as the soft block, of which glass transition temperature is in the vicinity of the temperature of use of the washing machine.
  • a material is selected as the hard blocks in view of requirements of mechanical properties, such as hardness.
  • mechanical properties such as hardness.
  • Shore hardness is approx. 80.
  • the hardness is low, in general, approx. 30 in Shore A hardness.
  • the hard block is polystyrene
  • the soft block is polyisoprene, particularly, vinyl-polyisoprene.
  • the block copolymer may be used solely, at least one selected from olefin based thermo plastic resin, ethylene- ⁇ olefin copolymer, ethylene-vinylacetate copolymer, ethylene-ethylacrylrate copolymer, styrene-butadiene-styrene copolymer, and styrene-isoprene-styrene copolymer may be blended with the block copolymer.
  • additives such as cross-linker, filler, and softner, may be introduced into a base material of the block copolymer, that is known to a person skilled in the field of art, of which detailed description will be omitted.
  • the leg pad of the block copolymer of hard block and soft block enables to fabricate a leg pad that satisfies the vibration attenuation characteristic and other required properties very much.
  • a test is carried out on a material that substantially satisfies above conditions among commercially available materials.
  • the material used in the test is Kuraray Hybrar.
  • the Hybrar a block copolymer of polystyrene and polyisoprene, has a glass transition temperature in the vicinity of room temperature of approx. ⁇ 19° C. ⁇ 8° C.
  • FIG. 7 it is verified that the leg pad of the Hybrar has very good damping force in the vicinity of room temperature.
  • the material of the leg pad in the sample 1 a and the sample 2 a is Hybrar.
  • the material suitable for the leg pad is not limited to Hybrar, and any material that satisfies above conditions can be used.
  • the leg pad has, not only an excellent vibration attenuation characteristic, but also excellent formability and workability taking production cost of the washing machine into consideration.
