Abstract: PURPOSE:To allow each caster to be operated at any time without a hitch even when it is adapted to a high-low bed the floor of which can be adjusted in height by constituting a mechanism to be locked and/or released with the locking mechanism of each caster manually operated. CONSTITUTION:The caster lock mechanism 10 of a caster is provided for the trolley frame 12 of a bed 11 the floor of which can be adjusted in height. In order that the casters 13a through 13d are, for example, to be locked, the lever 33 of No.1 manual operating mechanism 19 is fulled out, a wire 23 is pulled in to the side of a foot board 29 while being slid in a wire tube 21, and a drive chain 18 is moved to one direction via a wire chain stationary member 25. Accompanied with this movement, sprockets 17a through 17d are driven to the same direction so as to be rotated, so that a cam member 38a is thereby rotated via No1 bevel gears 15a through 15d, No.2 bevel gears 16a through 16d, and a rotating shaft 40. An interlocking shaft 37a is then abutted against No.1 recessed section 41a while a rotation check piece 36a is being pressed onto the caster 13a against the repulsive force of a spring member 39a, so that the caster 13a is thereby locked.

Title: Zoom lens
Inventor: OGATA YASUSHI
IPC: G02B15/20
Filed: 1988-06-07
Abstract: PURPOSE:To obtain excellent image plane performance over the entire power variation range by constituting a three-group zoom lens by providing an air gap which is movable at the time of zooming in the 1st or 2nd group of a two-group zoom lens whose 1st group has positive refracting power. CONSTITUTION:This zoom lens consists of the 1st group G11 which has positive or negative refracting power, the 2nd group G12 which has positive refracting power, and the 3rd group G2 which has negative refracting power. Then when the power is varied from the wide-angle end to the telephoto side, the group gap between the 1st group G11 and 2nd group G12 increases in the beginning and then decreases nearby intermediate focal length and thus the variation of the gap has an inflection point in the middle. The group gas between the 2nd group G12 and 3rd group G2, on the other hand, decreases monotoneously from the wide-angle side to the telephoto side. Consequently, the overall length of the lens system becomes short and variation of aberrations becomes small to make, specially, the curvature of field excellent, so the excellent image formation performance is obtained over the entire power variation range.
