More specifically, the present invention relates to a handheld heated sander device comprised of a body or housing having a bottom surface, one or more controls or buttons, a power source, a motor, a blower, a heating element, a vacuum and a sanding disc. The heating element may be located internally or externally of the housing and is used to heat a flow of air, and the blower is used to expel the heated air onto a workpiece as its being sanded. The bottom surface is comprised of at least one continuous opening and a fastening system that allows the sanding disc to be removably attached to the bottom surface. The sanding disc is also comprised of at least one continuous opening that aligns with the continuous opening of the bottom surface to allow a waste created by the sanding operation to be vacuumed into a waste bag attached to the heated sander device. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices and methods of manufacture.
Sanders are commonly used amongst carpenters and laymen to accomplish a multitude of tasks. However, time is ultimately wasted when sanding surfaces because traditional sanding devices lack the ability to produce heat, which prevents the device from reaching particles deep in a wood grain. This in turn forces a user to sand excessively in order to reach the deeper particles, which may cause a user to spend copious amounts of time and energy sanding the workpiece, which is both inefficient and tim consuming. Further, paint strippers, sanders, and heat guns are all different devices that a user must purchase separately to accomplish relatively similar tasks if they wish to apply heat while sanding.
Therefore, there exists a long-felt need in the art for an improved sander device. There also exists a long-felt need in the art for a heated sander device that allows the user to access the deeper grains in a wood workpiece in a more efficient manner. Further, there exists a long-felt need in the art for a heated sander device that eliminates the need to have a paint stripper, sander, and a heat gun used separately to accomplished the same desired heated sanding effect. Moreover, there is a long-felt need in the art for a heated sander device that enables a user to simultaneously heat, blow and sand a workpiece, and then clean up the waste in an efficient and timely manner.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a heated sander device. The device is primarily comprised of a housing, a bottom surface, one or more controls, a power source in the form of an electrical cord or one or more batteries, a motor, a blower, a vacuum, at least one heating element and a sanding disc. The heating element is powered by the power source and can be controlled by the one or more controls, such that heated air is produced from the device internally or externally in differing embodiments and applied to the workpiece in an efficient manner. The bottom surface comprises at least one continuous opening in fluid communication with the blower and/or the vacuum source and a fastening system that allows a sanding disc to be removably attached to the bottom surface. Likewise, the sanding disc also comprises at least one continuous opening that aligns with the continuous opening of the bottom surface to allow heated air or waste to flow therethrough.
In this manner, the heated sander device of the present invention accomplishes all of the forgoing objectives and provides an improved means to perform the task of sanding, paint stripping, heating, simultaneously. Further, the heated sander device uses a flow of heated air to help loosen deep areas in the wood to achieve a more efficient sanding operation.
