A method for manufacturing a wrist rest device includes manufacturing a prototype of the wrist rest device, and applying or spraying a gelatinous or polyurethane system material onto an outer peripheral portion of the prototype, for forming a polyurethane skin on the outer peripheral portion of the prototype. The polyurethane system material is applied onto the prototype after the prototype has been formed, such that no peripheral skirt will be formed around the wrist rest device, and no trimming processes are required for trimming or removing the peripheral skirt from the wrist rest device.

1. Field of the Invention
The present invention relates to a method, and more particularly to a method for manufacturing wrist rest apparatuses.
2. Description of the Prior Art
FIG. 1 is a cross sectional view illustrating a typical molding device for manufacturing the typical wrist rest apparatuses;
FIGS. 2, 3 are perspective views illustrating two typical wrist rest apparatuses manufactured by the typical wrist rest manufacturing methods;
FIGS. 4, 5, 6, 7 are cross sectional views illustrating the processes of a method in accordance with the present invention for manufacturing a wrist rest apparatus; and
Referring to the drawings, a method in accordance with the present invention is provided for easily and quickly manufacturing a wrist rest apparatus without forming a peripheral skirt or flange around the peripheral portion of the wrist rest apparatus, for allowing the wrist rest apparatus to be manufactured without final trimming processes.
For example, as shown in FIGS. 4 and 5, one or more mold devices 10 may be provided for manufacturing or forming the prototype 40 (FIGS. 6, 7) of the wrist rest apparatus. The mold device 10 comprises a mold cavity 11 formed therein and formed according to the shapes of the wrist rest apparatuses to be formed. For example, the mold device 10 may include a deeper portion or chamber 12 having a shape corresponding to that of the pad portion 20 (FIGS. 6-8) of the wrist rest apparatus, and/or a shallower portion or recess 14 having a shape corresponding to that of the base portion 30 of the wrist rest apparatus.
As shown in FIG. 4, a resilient or soft or deformable or gelatinous material, such as gel, or polyurethane (PU), or the other gelatinous materials, is first filled into the deeper chamber 12 of the mold device 10 for forming the pad portion 20 of the wrist rest apparatus. As shown in FIG. 5, another resilient or soft or deformable or gelatinous material, such as gel, or polyurethane (PU), or the other gelatinous materials. is then filled into the shallower recess 14 of the mold device 10 for forming the base portion 30 of the wrist rest apparatus.
