Abstract
A wheelchair scale is provided wherein triangular or trapezoidal box-shaped members are used for forming a support base having a truss structure. The box-shaped members are formed in advance by welding, and are then welded together. Since the welding processes can be performed separately, work efficiency is improved. In addition, since the support base has a truss structure, it supports a large amount of weight without deflection, even though its thickness is relatively small. In addition, the weight of the support base is reduced compared to a conventional base having a pipe structure. Furthermore, because the height of the support base from the floor is reduced compared to a typical conventional structure, a wheelchair can be easily moved onto the support base.
Claims20
A scale having a support base, the support base having a truss structure comprising a plurality of box-shaped members rigidly joined together.
A method of manufacturing a scale having a support base, the support base having a truss structure, the method comprising:
- providing a plurality of trapezoidal or triangular box-shaped members, each member having a bottom plate and a plurality of side plates with side surfaces;
- aligning the members such that a plurality of the side surfaces face each other;
- and
- welding the members to each other to form the truss structure.
A method of manufacturing a scale having a support base, the support base having a truss structure, the method comprising:
- providing a plurality of trapezoidal or triangular box-shaped members, each member having a plurality of side plates with flanges;
- aligning the members such that adjacent ones of the members contact each other substantially without gaps;
- and
- welding the members to each other to form the truss structure.
