Claims
[1] An apparatus for opening and closing a commode seat, which is disposed at a
commode and includes a commode main body; a commode seat disposed at the commode main body so as to allow the user to comfortably sit thereon; a rotation member disposed between an upper surface of the commode main body and the commode seat, and provided with a support portion for supporting one side of
the commode seat; and a cylinder having a piston rod adapted to convert the
rotation movement of the rotation member into a linear movement so as to be
moved forwardly and rearwardly,
wherein the commode seat opening and closing apparatus comprises:
a main body formed with a securing portion secured to one side of the main body of the commode by means of adhesion means, a first support shaft formed pro- trudingly at an opposite side to the securing portion, a thick portion and a reinforcing rib formed at one side thereof below the support shaft to prevent twist thereof, a second support shaft formed at one end of the thick portion, and a
securing hole formed thereon to correspond to the second shaft;
the cylinder fit into the securing hole and secured to the main body by fastening means, the cylinder being provided with the piston rod at the inside thereof so
that it can reciprocate;
the rotation member secured to one end of the piston rod by a first pin and fit into the first support shaft at the adjacent position so that it can rotate by a predetermined radius;
an elastic member engaged at one end of the rotation member by a second pin, and is engaged at the second support shaft at the other end thereof.
[2] The apparatus according to claim 1 , wherein the cylinder has a tapered inner wall surface, and at least one fluid passageway is formed thereon.
[3] The apparatus according to claim 1, wherein one end of the piston rod moving
forwardly and rearwardly in the cylinder by the rotation member is disposed to
penetrate through a closed end of the cylinder formed at the rear end, and a
compression member acting as a check valve is disposed at a mid portion to
operate against oil filled in the cylinder.
[4] The apparatus according to claim 3, wherein the compression member acting as the check valve includes:
key grooves formed at the piston rod with a desired interval therebetween;
a check valve holder secured between the key grooves by a snap ring, and
formed with an orifice at any portion thereof; and
a rubber packing member disposed at a circumferential surface of the check valve holder to be closely contacted with a wall body.
[5] The apparatus according to claim 1, wherein the elastic member is a tension
spring.
[6] The apparatus according to claim 1, wherein the elastic member is a rubber string with good elastic force and restoring force.
[7] An apparatus for opening and closing a commode seat, which is disposed at a
commode and includes a commode main body; a commode seat disposed at the commode main body so as to the user to comfortably sit thereon; a rotation
member disposed between an upper surface of the commode main body and the commode seat, and provided with a support portion for supporting one side of
the commode seat; and a cylinder having in a piston rod adapted to convert the
rotation movement of the rotation member into a linear movement so as to
moved forwardly and rearwardly,
wherein the commode seat opening and closing apparatus comprises:
a main body formed with a securing portion secured to one side of the main body of the commode by means of adhesion means, a first support shaft formed pro- trudingly at an opposite side to the securing portion, a thick portion and a reinforcing rib formed at one side thereof below the support shaft to prevent twist thereof, a second support shaft formed at one end of the thick portion, and a
securing hole formed thereon to correspond to the second shaft;
the cylinder fit into the securing hole and secured to the main body by fastening means, the cylinder being provided with a piston rod at the inside thereof so that it can reciprocate;
the rotation member secured to one end of the piston rod by a first pin and fit into the first support shaft at the adjacent position so that it can rotate by a predetermined radius;
an elastic member engaged at one end of the rotation member by a second pin, and is engaged at the second support shaft at the other end;
a tension adjustment device disposed between the second pin and the first
support shaft so that one end thereof is inserted into the elastic member so as to adjust the rotation force of the rotation member; and
a check valve holder formed integrally at one end of the piston rod.
[8] The apparatus according to claim 7, wherein the tension adjustment device
includes an elongate rectangular shaped body formed with a plurality of holes or grooves opened to one side at uniform interval, and a protrusion at one end of the body so that it can be fit between the elastic members.
[9] The apparatus according to claim 7, wherein the cylinder is provided with one
open end screw engaged with a plug, and the other closed end, and the plug is provided with an o-ring or a bushing for preventing the leakage of oil in the cylinder, and the check valve is provided at the upper portion of the check valve holder with a control plate for opening and closing an oil passageway according to the operation of the piston rod; and a hook formed protrudingly at the upper portion of the check valve holder for preventing the separation and controlling the movement of the control plate.
