Hand brake mechanism for a central processing unit cabinet

A hand brake mechanism for a cabinet, said cabinet having wheels mounted on a bottom surface for moving said cabinet, said wheels having spokes, comprising:

• a base having two sides and a groove substantially formed in a central part thereof, said base being fixed to the bottom of said cabinet and located generally between said wheels, said base having first and second lateral holes extending from said sides to said groove;
• a handle slidably mounted on said groove substantially between a first wheel and a second wheel;
• a first engaging rod disposed in said first lateral hole to engage said spokes of said first wheel;
• a second engaging rod disposed in said second lateral hole to engage said spokes of said second wheel;
• means for resiliently maintaining said first engaging rod between spokes of said first wheel;
• means for resiliently maintaining said second engaging rod between spokes of said second wheel;
• means, responsive to sliding said handle, for disengaging said first engaging rod from between said spokes of said first wheel by resiliently deforming said means for resiliently maintaining said first engaging rod between spokes of said first wheel, and for disengaging said second engaging rod from between said spokes of said second wheel by resiliently deforming said means for resiliently maintaining said second engaging rod between spokes of said second wheel.

A hand brake mechanism for a cabinet having at least two wheels mounted on a bottom surface of the cabinet, the wheels having spokes, comprising:

• a base having two sides and a groove substantially formed in a central part of said base, said base fixed to the bottom of the cabinet and located generally between the wheels, said base having a lateral hole extending from each of said two sides to said groove;
• a handle slidably mounted on said groove;
• an engaging rod disposed in each of said lateral holes to engage the spokes of the wheels, each of said engaging rods having a guide pin protruding over said groove;
• means for resiliently maintaining said engaging rods between the spokes of the wheels;
• means, rigidly attached to said slidable handle, for disengaging said engaging rods from between the spokes of the wheels, said disengaging means including guide plates having an oblique angled inner edge for moving said guide pins of said engaging rods laterally with respect to the wheels.
