Definitions

  • the present invention relates to a cushioning device according to the preamble of claim 1, 4 or 7.
  • Indoor units of air conditioners to be shipped from a factory are typically arranged so that its end portion or corner portion is fitted with a cushioning device made of expanded polystyrene or the like, In order to prevent the indoor units from receiving impact of vibrations during the transportation or the like (see JP-A-2007-137464 and JP-U-60-115885 , for example).
  • JP-A-2007-137464 teaches that a pair of cushioning devices, which have fitting recesses fitted respectively with one end portion and the other end portion of an indoor unit, are arranged so that the cushioning device fitted with one end portion near the barycentric position of the indoor unit is arranged to be thicker than the cushioning device fitted with the other end portion. In this way, the impact load on the indoor unit fitted with a pair of cushioning devices is lessened when the indoor unit is dropped.
  • JP-U-60 115 885 above also recites a cushioning device which is arranged so that a fitting recess fitted with an end portion of an indoor unit has a recess toward the depth of the device.
  • JP-U-60-115885 which represents the closest prior art discloses a cushioning device having a fitting recess fitted with a longitudinal end portion of an indoor unit of an air conditioner, wherein the indoor unit is arranged to be mounted on a wall.
  • a gap is provided in the side of the recess opposing the side cover of the indoor unit in order to prevent bulging of the front cover when side forces are exerted on the indoor unit.
  • Indoor units mounted in the cushioning devices recited in JP-A-2007-137464 and JP-U-60-115885 are typically packed in cardboard boxes 903 and piled up in plural layers, as shown in Fig. 13 .
  • the indoor units 902b of the lower layer receive the load of the indoor units 902a of the upper layer.
  • This arrangement is disadvantageous in that the indoor units 902b of the lower layer are pushed onto the bottom portions 915 of the cushioning devices 901 on account of the load of the indoor units 902a of the upper layer, and cover members 922 constituting the exterior of the indoor unit 902b are deformed as they are pushed onto the bottom portion 915 of the cushioning device 901.
  • a lower cover member 922a which extends along the length of the indoor unit 902b and is provided on the lower side the indoor unit 902b when wall mounted and an upper cover member 922b which extends along the length of the indoor unit 902b and is provided on the upper side the indoor unit 902b when wall mounted are thin and easily deformable, and hence these members are significantly deformed.
  • side cover members (not illustrated) extending in the directions perpendicular to the length of the indoor unit and disposed on the respective sides of the indoor unit when wall mounted are arranged not to be easily deformed because they contact the cushioning device 901.
  • the lower cover member 922a and the upper cover member 922b may be fixed by using tapes or the like (not illustrated) to prevent the lower cover member 922a and the upper cover member 922b from deforming even if they are pushed onto the bottom portion 915.

  • the cushioning devices 1a and 1b are also advantageous in that, even if the lower cover member 22a and the upper cover member 22b of the indoor unit 2 are thin and easily warped, the edge portion 221a of the lower cover member 22a and the edge portion 221b of the upper cover member 22b do not deform because they do not contact the bottom portion 15. For this reason, it is unnecessary to increase the strength of the cover members 22 by means of the selection of suitable material and thickness to restrain the deformation of the lower cover member 22a and the upper cover member 22b. Furthermore, it is unnecessary to increase the strength of the cushioning devices 1a and 1b by means of the selection of suitable material and thickness.

  • the bottom portion 115 of the cushioning device 101a has a recess 115a at a part opposing an edge portion 1221a of a lower cover member 122a. Therefore, when the lower corner portion of the indoor unit 102 is fitted with the fitting recess 110a, there is a gap between the edge portion 1221a of the lower cover member 122a and the bottom portion 115.
  • the bottom portion of the cushioning device 101c has a recess (not illustrated) at a part opposing the edge portion of the upper cover member. Therefore, when the upper corner portion of the indoor unit 102 is fitted with the fitting recess, there is a gap between the edge portion of the upper cover member and the bottom portion.
  • the embodiment above describes a case where a bottom portion has recesses at parts opposing the edge portion of the lower cover member and the edge portion of the upper cover member so that gaps are formed between the bottom portion and the cover members.
  • the present invention may be alternatively arranged so that a gap between the bottom portion and the cover member is formed by providing, in the bottom portion, a protrusion at a part corresponding to the mounting board (i.e. at a part different from the parts opposing the edge portions of the lower cover member and the upper cover member).
  • the embodiment above describes a case where recesses are formed in the bottom portion in order to form gaps between the edge portion of the lower cover member and the bottom portion and between the edge portion of the upper cover member and the bottom portion.
  • the present invention may be alternatively arranged so that, as in the case of a cushioning device 201a of First Variation of Fig. 7 , a protrusion 215a may be formed at a part of the bottom portion 215 which part opposes the edge portion of the side cover member which is along the direction (S direction) orthogonal to the length of the indoor unit (i.e. L direction) and at the end portion of the indoor unit in the longitudinal direction when wall mounted. It is possible also in this case to form gaps between the edge portion of the lower cover member and the bottom portion and between the edge portion of the upper cover member and the bottom portion.
  • the embodiment above describes a case where recesses are formed at parts opposing the edge portion of the lower cover member and the edge portion of the upper cover member.
  • the present invention is not limited to this arrangement, and hence the recesses may be variously shaped as long as gaps are formed between the edge portion of the lower cover member and the bottom portion and between the edge portion of the upper cover member and the bottom portion.
  • recesses 315a and 315b may be formed which have widths W1 and W2 longer than those of the recesses 15a and 15b of the cushioning device 1a of First Embodiment.
  • a recess 415c may be formed at a part supporting the mounting board, in addition to recesses 415a and 415b which are identical with the recesses 315a and 315b of the cushioning device 301a of Third Variation.
  • the material of the cushioning device is reduced because of the enlargement of the widths of the recesses 315a, 315b, 415a, and 415b and required for providing the recess 415c.
  • the embodiment above describes the cushioning devices 1a and 1b attached to cover the one end portion 2a and the other end portion 2b of the indoor unit 2.
  • the present invention may be alternatively arranged so that a cushioning device is fitted to corner portions on the back side of the end portion of the indoor unit, as in the case of a cushioning device (first member) 501a of Fourth Variation shown in Fig. 10 .
  • This cushioning device 501a has: a recess 515a at a part opposing the edge portion of the lower cover member; a recess 515b at a part opposing the edge portion of the upper cover member; and a recess 515c at a part opposing the edge portion of the side cover member.
  • the recesses 515a, 515b, and 515c are provided to form substantially a U-shape.
  • This cushioning device 501a is paired with a cushioning device 501b (second member) fitted with the corner portions on the front side of the end portion of the indoor unit.
  • the arrangement above is advantageous in that, when the recess 515c is formed by using a die, the recess 515c is easily formed because the removal of the die is easy as two cushioning devices 501a and 501b are used.
  • the embodiment above describes an example where recesses are formed to oppose the edge portion of the lower cover member and the edge portion of the upper cover member.
  • the present invention may be alternatively arranged so that, as in the case of a cushioning device 601a of Fifth Variation shown in Fig. 11 , a recess 615c is formed at a part opposing the edge portion of the side cover member provided at the end portion of the indoor unit, in addition to the recess 615a opposing the edge portion of the lower cover member and the recess 615b opposing the edge portion of the upper cover member.
  • the above-described arrangement is advantageous in that, since the edge portion of the side cover member is not pushed onto the bottom surface 615 of the fitting recess, it is possible to prevent not only the lower cover member and the upper cover member but also the side cover member from warping. This prevents the lower cover member, the upper cover member, and the side cover member of the indoor unit from deforming when stacked.
  • the embodiment above describes an example where, since the upper cover member is formed so that a gap with the wall is narrow when wall mounted, the bottom portion is provided with a recess at a part opposing the edge portion of the upper cover member.
  • the present invention is not limited to this arrangement.
  • FIG. 12 shows, when a recess 715a is formed at a part opposing the edge portion 7221a of the lower cover member 722a of the indoor unit 702 whereas the edge portion 7221b of the upper cover member 722b is formed to secure a large gap between the unit 702 and the wall when wall mounted, it is not necessary in the bottom portion 715 to form a recess opposing the edge portion 7221b of the upper cover member 722b. This is because the large gap between the edge portion 7221b of the upper cover member 722b and the wall is formed in order to allow the indoor unit 702 to be easily fitted with the mounting board 723 attached to the wall.
  • the present invention makes it possible to restrain the deformation of cover members of an indoor unit, which plural indoor units are stacked.
