  • Patent number: 5181289
    Abstract: A bed apparatus having a lifting mechanism including sliders, upright bars, support members and side bars, is equipped with a coupling rail above the side bars to be vertically movable with the side bars. A rehabilitation attachment with a pulley is movably mounted on the rail. A rope is extended around the pulley so that a sick person or the like can alternately pull the ends of the rope with the left and right hand for exercising the hands and arms. The person's feet may be connected to one end of the rope while pulling the other end of the rope with the hands for exercising the person's limbs.

  • Patent number: 5177822
    Abstract: A pair of sliders (4, 5) are mounted on both end portions of a bed body (3) for sliding along said end portions in the cross direction of the bed body (3). Upright bars (6, 7) are mounted on the respective sliders (4, 5) to upwardly extend from the sliders (4, 5). Support members (8, 9) mounted on the respective upright bars (6, 7) are movable along the upright bars (6, 7) and stoppable at adjusted positions. Two parallel side bars (10, 11) couple the support members (8, 9) of a pair with each other. The respective upright bars (6, 7) are movable with respect to the sliders (4, 5) along the cross direction of the bed body (3), whereby the upright bars (6, 7) can be moved to ends of the sliders (4, 5) when the sliders extend laterally from the bed body (3) and outside the bed body (3). As the result, the bed body (3) will not hinder any nursing of a sick person or the like, who is held by the side bars (10, 11) and can be attended at the side of the bed body (3).

  • Patent number: 5173978
    Abstract: A bed apparatus (1) combines a bed body (3) and a collapsible bathtub (103). The bathtub (103) is vertically collapsible to be storable in a spaced under a bottom plate (106) of the bed body (3). The collapsible tub is movable by a guide member (104) between a position under the bottom plate (106) and a position on a side of the bottom plate (106). In an unused state, the bathtub (103) is stored in the space under the bed body in order to facilitate an effective use of a relatively narrow room.

  • Patent number: 4958885
    Abstract: A high chair has a backrest member and a seat member which constitute a seat section, and a support member which is disposed to overlap the backrest member and which supports the backrest member for vertical slide movement. The support member is fixed in its raised position by a raised position fixing device. In the region where the backrest member and the support member overlap each other, the support member has a through-hole. On the other hand, a plurality of vertically aligned engaging holes are provided in the backrest member at positions where they can be opposed to the through-hole. A lock pin is inserted into the through-hole and one of the engaging holes, thereby fixing the height of the backrest member.

  • Patent number: 4906017
    Abstract: A baby carriage comprises a pair of push rods, a push rod connecting member for connecting upper end portions of the pair of push rods with each other, a pair of push rod locking members for fixing positions of the push rods, a pair of opened state locking members for fixing/maintaining the baby carriage in an opened state, a pair of engagement release members provided to be displaceable between lowermost, intermediate and uppermost positions along the push rods, a wire for connecting the pair of engagement release members with each other and an operating member connected to the wire at the central portion of the push rod connecting member. When the operating member is manually brought into a second position, the engagement release members are pulled up by the wire toward the intermediate positions, to push up the opened state locking members. Consequently, the baby carriage is released from the locked opened state.

  • Patent number: 4861405
    Abstract: A laminated continuous sheet which, when cut, forms individual disposable diapers is moved at high speed in the direction of the length thereof, whereby in an air zone of predetermined thickness disposed on at least a predetermined surface of the laminated continuous sheet, there is produced with the travel of the laminated continuous sheet an air flow having a velocity gradient such that the speed of the air flow increases as the predetermined surface is approached. Baby powder is fed at a position within the air zone of predetermined thickness so that it contacts the air zone. By utilizing a decreasing-pressure phenomenon produced by the air flow having a velocity gradient described above in which the pressure decrease as the predetermined surface of the laminated continuous sheet is approached, baby powder is caused to adhere to the predetermined surface as it is drawn toward the predetermined surface of the laminated continuous sheet.

  • Patent number: 4845805
    Abstract: A caster has a fixed bracket (15), a rotary yoke (16) rotatably supported on the fixed bracket (15), and a wheel (2) rotatably supported on the rotary yoke (16) by a horizontal axle (16). The axle (16) is mounted for movement in a predetermined range in a horizontal plane in a direction which is at right angles to the axle. The rotary yoke (16) includes an automatic locking member (17) capable of moving between first and second positions in response to the movement of the horizontal axle. The fixed bracket (15) is provided with an engaging recess (36) for engaging the automatic locking member (17) to inhibit the rotation of the rotary yoke (16) when the fixed bracket (15) and the rotary yoke (16) are in a predetermined positional relationship and when the automatic locking member (17) is in the first position.
