Definitions

  • the present invention relates to an auxiliary escalation unit for bed escalators, and more particularly relates to an improvement for smooth initial escalation of a supporting board of an escalation unit suited for supporting wheel chair and electromotive beds used for aged people and care patients.
  • a supporting board is required to perform escalation whilst carrying a considerably heavy load such as a user thereon. Due to this basic mechanism, it is highly difficult to assure smooth initial escalation.
  • the escalation device of the above-described prior proposal utilizes a movable opener and, during the original escalation stage, the opener comes in contact with an abutment incorporated in its pantograph mechanism to assist initial opening of the pantograph mechanism for smooth escalation of the supporting board.
  • an auxiliary escalation unit includes a pedestal, a supporting board and a hydraulic cylinder.
  • the hydraulic cylinder is pivoted at the lower end to the pedestal and carries an escalating roller via an L-lever. In the descending position of the supporting board, the escalating roller is in contact with an abutment associated with the supporting board.
  • the auxiliary escalation unit is actuated for operation to make the L-lever escalate the supporting board to some extent via the escalating roller and the abutment so that cooperation of the main and auxiliary escalation units enables smooth initial escalation of the supporting board.
  • the auxiliary escalation unit of the present invention is not in mechanical engagement of the main escalation unit, the auxiliary escalation unit is suited for combination with any type of main escalation unit.
  • FIG. 1 A preferred embodiment of the auxiliary escalation unit in accordance with the present invention is shown in Figs. 1 and 2.
  • a supporting board 5 is supported on a pedestal 1 via legs 3. Although only two legs 3 are shown in the illustration, four legs 3 are provided usually.
  • Each leg 3 is pivoted at the lower end to the pedestal 1 and pivoted at the upper end to the supporting board 5.
  • the pivoted lower end of one leg 3, the right side end in the illustration, is movable in the longitudinal direction of the pedestal 1 along a horizontal rail (not shown) affixed to the pedestal 1.
  • the pivoted upper end of the other leg 3, the left side end in the illustration, is movable in the longitudinal direction of the supporting board 5 along a horizontal rail (not shown) affixed to the supporting board 5.
  • An auxiliary leg 7 is pivoted at the lower end to the midway of one leg 3, the left side leg 3 in the illustration, and pivoted at the upper end to the supporting board 5.
  • a drive motor 9 is pivoted at the proximal end to the supporting board 5 and its piston rod 11 is pivoted at the distal end to the lower end of a link 13.
  • the upper end of the link 13 is pivoted to the first stationary shaft 15 supported by the supporting board 5 and extending horizontally in a direction normal to the longitudinal direction of the supporting board 5.
  • An arm 17 integral with the link 13 is pivoted at the upper end to the stationary shaft 15.
  • a connecting rod 19 is pivoted at one end, a left side end in the illustration, to the lower end of the arm 17 and at the other end, a right side end in the illustration, to the lower end of an arm 21.
  • the arm 21 On the side of the left side foot 3, the arm 21 is pivoted at the upper end to the second stationary shaft 23 fixed on the leg 3, the right side leg in the illustration.
  • the stationary shaft 23 extends horizontally in a direction parallel to the first stationary shaft 15.
  • the main escalation unit of the above-described construction operates as follows;
  • the drive motor 9 is switched on at starting of ascent of the supporting board 5. Its piston rod 11 advances to rotate the link 13 and the arm 17 clockwise in the illustration. Then the connecting rod 19 is pulled leftwards in the illustration to force the arm 21 rotate clockwise in the illustration. This rotation causes standing rotation of the leg 3, the right side leg 3 in the illustration, thereby pushing up the supporting board 5.
  • the drive motor 9 is switched off at starting of descent of supporting board 5. In this state, all the related parts perform movements opposite to the ascending stage so that the right side leg 3 performs anti-standing rotation to pull down the supporting board 5.
  • auxiliary escalation unit is associated with the right side leg 3 only in the case of the illustrated embodiment, all the legs should preferably associated with the auxiliary escalation unit in accordance with the present invention.
  • a hydraulic cylinder 25 having a piston rod 27 is pivoted at the proximal end to the pedestal 1.
  • a pneumatic cylinder is generally used for the hydraulic cylinder.
  • An upright stand 29 on the pedestal 1 pivotally supports the apex of an L-lever 31 whose lower branch is pivotally connected at the lower end to the tip of the piston rod 27 of the hydraulic cylinder 25.
  • the upper end of its upper branch carries an escalating roller 33.
  • the hydraulic cylinder 25 Prior to starting of ascent of the supporting board 5, the hydraulic cylinder 25 is actuated and its piston rod advances to rotate the L-lever 31 about its pivotal apex clockwise in the illustration. As a result, the escalating roller 33 at the upper end of the upper branch of the L-lever 31 pushes up the abutment 35 with its associated supporting board 5. Soon after the hydraulic cylinder is stopped in operation and its piston rod 27 recedes to the initial position. Just prior to this stage or concurrently with this timing, the main escalation unit is driven for the above-described operation.
  • the main escalation unit may be driven for concurrent operation with the auxiliary escalation unit or, as in the above-described embodiment, may be driven for operation with some delay from that of the auxiliary escalation unit. In either case, cooperation of the main and auxiliary escalation units assure smooth starting escalation of the entire system.
  • the auxiliary escalation unit in accordance with the present invention is widely employable in the industrial field such as hospitals and care business for aged and bodily cripples people wherein beds are used.
  • FIG. 3 A variant of the above-described auxiliary escalation unit is shown in Fig. 3, in the supporting board 5 is provided with a detachable head board 121, a detachable foot board 125 and a pair of detachable side rails 123. When the supporting board 5 is used as a home bedding, these additional parts may be detached from the supporting board 5.
