  • Cart and carrier for medical equipment
    Patent number: 6698770
    Abstract: In a cart and a carrier for medical equipment, the carrier has a bottom section and a back section and a pair of wheels and is arranged on an axle at the junction between the bottom section and the back section. The axle functions as a pivot axle and the back section as a lever for lifting the entire bottom section off the floor when the carrier is moved. Smooth and convenient interaction between the cart and carrier is achieved because the cart has a receiving part and a first locking part, and the carrier has a coupling arrangement and a second locking part. The coupling arrangement can be inserted into the receiving part and serves as a pivot axle for the carrier. The carrier locks to the cart when the second locking part is moved toward the first locking part when the carrier is lifted around the pivot axle.
