FIELD: medical equipment. ^ SUBSTANCE: grating is made composed of several members connected for dismounting due to application of bending force. Connection of members is achieved due to edge grooves and protrusions of members. Edge protrusions are formed by prolongation of parts of longitudinal rods. Ends of the rods are connected in pairs from the bottom by lateral cylindrical straight arch for interaction when mounting members with corresponding adjacent cross-lateral rod. Diameter of strap is bigger than diameter of lateral rod. ^ EFFECT: changeable sizes of grating; improved comfort at use. ^ 3 cl, 12 dwg |
