Definitions

  • the present disclosure relates to a device which enables a wheelchair user to easily move large rear-wheels of a wheelchair, which are obstructions when getting in or off, rearward of the wheelchair when the wheelchair user wants to get in and off of a chair or bed in a self-propelled wheelchair with large wheels that can be driven by the user using both arms.
  • a nurse or guardian may lift a user with hands and move the user, or may put a transfer band on the wheelchair user and put the wheelchair user on or off of the wheelchair through the transfer band. Both methods are very difficult to use because the wheelchair user is transferred by human power, and thus, it gives a very heavy burden on the nurse or guardian.
  • a separate device such as a hoist or a lifter may be used to pick up or drop off the user, but this method also has inconvenience of using a separate external device.
  • the method most often used by the wheelchair user to get in or off a self-propelled wheel body having large wheels that can be driven by the user using both arms is a method of using a sliding board.
  • the user lays the sliding board across a wheelchair seat and a bed and moves across by sliding his or her buttocks ( US 4,288,124 , US 4,987,621 , US 5,067,188 , US 5,152,016 , US 5,193,233 , US 5,735,002 , US 5,947,501 , and US 6,748,612 ).
  • the biggest challenge of this method is that the large size of the wheelchair rear-wheels makes it difficult to mount the sliding board on a side surface of the wheelchair.
  • US 6,748,612 instead of moving the wheelchair wheels to the rear, a technology of installing a separate cradle above the wheelchair wheels and then using the cradle as a sliding board is proposed.
  • the present disclosure proposes a mechanism that allows the wheelchair user to easily move the wheelchair wheels to the rear by using wheelchair armrests alone without the help of a nurse or guardian.
  • a wheelchair user In a self-propelled wheelchair having large wheelchair wheels, a wheelchair user should be able to easily move the large wheels to the rear without a help of a guardian.
  • the wheelchair since the wheelchair is a passive wheelchair, it is difficult to use when a device that moves the wheelchair wheels to the rear is large or heavy. There is a need to develop a lightweight device that allows a wheelchair user to easily move the wheelchair wheels to the rear by himself/herself.
  • a wheelchair armrest serving as a side protector should be removed or rotated to the rear side of a wheelchair back support.
  • the armrest to be removed or rotated is used as a lever to move the wheelchair wheels to the rear.
  • a central axis of the wheelchair wheel should move in a straight line.
  • the wheelchair armrest As a lever, it is necessary to develop a mechanism that allows the central axis of the wheelchair wheel to move in a straight line while the wheelchair wheels roll.
  • an armrest fixing device needs to prevent the armrest from moving easily when the wheelchair travels.
  • FIG. 1 illustrates an overall appearance of a mechanism for moving large wheels of a self-propelled wheelchair to the rear.
  • a wheelchair frame 110 of the present disclosure has a different appearance from that of a general wheelchair frame.
  • the frame supporting the wheelchair wheel should be connected to the rear portion.
  • a guide rail 111 for supporting wheelchair wheel may be added to the wheelchair frame.
  • the wheelchair frame 110 of FIG. 1 is extended to the rear portion, unlike a general wheelchair, to move the wheelchair wheel to the rear while supporting a load of the wheelchair. As illustrated in FIG. 3A , the extended wheelchair frame does not come out of the wheelchair wheels 220, and thus, it is not inconvenient in terms of aesthetics and practical use.
  • the wheelchair includes a wheelchair armrest 150, in order to get on or off the wheelchair, and the user removes the wheelchair armrest 150 or rotates the wheelchair armrest 150 to the rear side of a wheelchair back support 210 in order to get in or off of the wheelchair.
  • a method of rotating the wheelchair armrest more than 90° to the rear side of the wheelchair back support is used.
  • the armrest 150 of the present disclosure is not fixed to the wheelchair frame, but is connected to a pivot link 140 for moving the wheelchair wheels 220 to the rear as illustrated in Figs 1 and 2 .
  • a straight guide module 121 equipped with a wheelchair wheel shaft support 122 may easily move in a straight direction along the wheelchair frame 110 or guide rail 111 through a straight guide slider 120.
  • the straight guide module 121 is connected to the pivot link 140, and the pivot link 140 rotates about a pivot 130 attached to the wheelchair frame.
  • a pivot guide slider 123 installed on the pivot link 140 has a sliding structure or variable structures 141 and 142 in which a length of the pivot link is changed as illustrated in FIG. 7 . Through this, it is possible to generate a straight line movement of the straight guide slider 120 or the straight guide module 121.
  • the pivot 130 is fixed to the wheelchair frame 110, and thus, becomes a center of rotation of the pivot link 140.
  • An end of the wheelchair armrest 150 is connected to the pivot link 140.
  • the straight guide module 121 connected to the pivot link 140 moves in a straight direction.
  • the pivot guide slider 123 installed on the pivot link 140 slides, or the wheelchair wheels are moved forward or rearward through the variable structures 141 and 142 by which the length of the pivot link 140 is changed.
  • FIG. 3 illustrates a step-by-step process in which the wheelchair wheels 220 are moved to the rear while the wheelchair armrest 150 rotates about the pivot 130.
  • the straight guide module 121 having the wheelchair wheel shaft support 122 and the straight guide slider 120 moves in a straight line along the wheelchair frame 110 or the guide rail 111, sliding occurs through the pivot guide slider 123 installed on the pivot link 140 or the lengths of the variable structures 141 and 142 of the pivot link are changed.
  • a side protector 180 attached to the wheelchair frame is pulled out and laid on a chair or a patient bed.
  • a height of a wheelchair seat and a height of the chair or patient bed of which the user is to get in or off do not match each other. Accordingly, the side protector can be easily laid on the chair or patient bed with different heights through a side protector connecter 190 capable of adjusting a height.
  • the user When the wheelchair user gets in or off of the chair or the patient bed from the wheelchair, as illustrated in FIG. 4 , the user lays the side protector 180 on the chair or patient bed, and then naturally presses the side protector 180 to get on or off of the chair of patient bed.
  • the user presses the side protector 180 laid on the chair or patient bed with hands, and thus, when the user gets on or off of the wheelchair, the wheelchair is safely fixed to the patient bed so that the wheelchair does not overturn.
  • FIG. 5 illustrates wheelchair armrest fixing devices 170 and 171 that fix the wheelchair armrest 150 to the wheelchair frame.
  • the wheelchair armrest 150 is fixed to the wheelchair frame through the wheelchair armrest fixing device 170, the central axis of the wheelchair wheel cannot move forward or rearward when the wheelchair travels.
  • FIG. 6 illustrates an appearance of easily separating or attaching the large wheel of the wheelchair from the wheelchair frame.
  • the wheelchair wheel central axis pushing pin 222 When the wheelchair wheel central axis pushing pin 222 is pressed, the wheelchair wheel central axis fixing ball 223 is lowered so that the wheelchair wheel can be easily fixed or separated with respect to the wheelchair wheel shaft support 122.
  • the wheelchair wheel central axis pushing pin 222 When the wheelchair wheel central axis pushing pin 222 is not pushed, the wheelchair wheel central axis fixing ball 223 comes out so that the wheelchair wheels are fixed without being separated from the wheelchair wheel shaft support 122.
  • FIG. 7A illustrates the wheelchair frame 110 performing the role of the guide rail at the same time
  • FIG. 7B illustrates the wheelchair frame 110 and the guide rail 111 being separated from each other.
  • a wheelchair in which a large wheel can move rearward can provide new convenience to those who use the existing wheelchair.
  • the wheelchair can be very helpful for the elderly or patients who have difficulty moving alone to get in and off of a wheelchair.
  • the wheelchair can provide essential functions to the existing wheelchair, not a special wheelchair with special functions. Accordingly, the wheelchair can become a new standard for wheelchairs, and thus, can be sold in the existing wheelchair market.
