The present disclosure relates to random orbit sanders, and more particularly to battery powered random orbit sanders.
Random orbit sanders are used to smooth workpieces that include wood, metal, etc. Improvements in these tools are always sought after in the industry.
The present disclosure provides, in one aspect, an orbital sander that includes a housing, a motor within the housing, the motor including a drive shaft defining a motor axis, an eccentric drive unit coupled to the drive shaft and configured to convert rotation of the drive shaft to an orbit motion around the motor axis, a sanding pad defining a horizontal work plane and coupled to the eccentric drive unit for orbital motion about the motor axis, and a battery receptacle extending along the housing, the battery receptacle operable to receive a removable battery pack for providing electrical current to the motor, wherein the battery receptacle defines a battery axis along which the battery pack is installed and the battery axis forms an acute battery angle relative to the work plane.
The present disclosure provides, in another aspect, an orbital sander that includes a motor housing, a motor within the motor housing, the motor including a drive shaft defining a motor axis, a grip portion extending along a top of the motor housing, the grip portion defining a grip axis perpendicular to the motor axis and an end face that is parallel to the motor axis, an eccentric drive unit coupled to the drive shaft and configured to convert rotation of the drive shaft to an orbit motion around the motor axis, a sanding pad defining a horizontal work plane parallel to the grip axis and coupled to the eccentric drive unit for orbital motion about the motor axis, and a battery receptacle extending along the motor housing, the battery receptacle including a battery contact face that is parallel to the motor axis and perpendicular to the grip axis and inset from the end face of the grip portion, the battery receptacle operable to receive a removable battery pack for providing electrical current to the motor, wherein the battery receptacle defines a battery axis along which the battery pack is installed and wherein the battery axis forms an acute battery angle relative to the work plane.
The present disclosure provides, in yet another aspect, an orbital sander that includes a motor housing, a motor within the motor housing, the motor including a drive shaft defining a motor axis, a grip portion extending along a top of the motor housing, the grip portion defining a grip axis perpendicular to the motor axis, an eccentric drive unit coupled to the drive shaft and configured to convert rotation of the drive shaft to an orbit motion around the motor axis, a sanding pad defining a horizontal work plane parallel to the grip axis and coupled to the eccentric drive unit for orbital motion about the motor axis, a battery receptacle extending along the motor housing, and a battery isolator disposed within the battery receptacle, the battery isolator including at least one guide rail operable to receive a portion of a removable battery pack, wherein the at least one guide rail extends within a guide plane that is parallel to the motor axis and perpendicular to the grip axis, and wherein the at least one guide rail forms an acute battery angle relative to the work plane.
Other features and aspects of the disclosure will become apparent by consideration of the following detailed description and accompanying drawings.
Before any embodiments of the present disclosure are explained in detail, it is to be understood that the embodiments described herein are not limited in scope or application to the details of construction and the arrangement of components set forth in the following description or as illustrated in the following drawings. The devices described herein are capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

The random orbit sander 100 further includes a battery receptacle 120 formed on housing 102 at least partially the along the length of the motor housing 110 beneath the grip portion 114. The battery receptacle 120 includes a battery contact face 122 that is parallel to the motor axis 112 and perpendicular to the grip axis 116. Further, the battery contact face 122 is offset from, or spaced away from, the motor axis 112 by a second distance D2. In a particular aspect, the second distance D2 is less than the first distance D1 such that the battery contact face 122 is tucked under the grip portion 114 and the battery contact face 122 is inset apart from the end face 118 of the grip portion 114 by an amount equal to the first distance D1 minus the second distance D2. This arrangement is ergonomic and provides a relatively compact tool. Further, by placing the battery contact face 122 closer to the motor axis 112 than the end face 118 of the grip portion 114 of the housing 102, the balance of the random orbit sander 100 is substantially improved.
In particular, the second distance D2 is less than or equal to 0.95 times the first distance D1, such as less than or equal to 0.9 times the first distance D1, less than or equal to 0.85 times the first distance D1, or less than or equal to 0.8 times the first distance D1. In another aspect, the second distance D2 is greater than or equal to 0.6 times the first distance D1, greater than or equal to 0.65 times the first distance D1, greater than or equal to 0.7 times the first distance D1, or greater than or equal to 0.75 times the first distance D1. In another aspect, the second distance D2 is within a range between, and including, any of the maximum and minimum values of the second distance D2 as related to the first distance D1.

In a particular embodiment, the battery angle A is an acute angle with respect to the work plane 140. Specifically, the battery angle A is greater than or equal to two and one-half degrees (2.5°), such as greater than or equal to five degrees (5°), greater than or equal to seven and one-half degrees (7.5°), or greater than or equal to ten degrees (10°). In another embodiment, the battery angle A is less than or equal to thirty degrees (30°), such as less than or equal to twenty-five degrees (25°), less than or equal to twenty degrees (20°), or less than or equal to fifteen degrees (15°). It is to be understood that the battery angle A may be within a range between, and including, any of the minimum and maximum values for the battery angle A disclosed herein.
In a particular aspect, the battery angle A allows the battery pack 128 to be tilted, or angled, with respect to the housing 102 of the random orbit sander 100 when the battery pack 128 is engaged therewith. Tilting the battery pack 128, as shown in at least
The removable battery pack 128 is slidable in a direction perpendicular to the grip axis 116 in a first direction (downward) along the battery axis 136 to be engaged with the battery receptacle 120 and in a second direction opposite the first direction (upward) along the battery axis 136 to be disengaged from the battery receptacle 120. In a particular aspect, the removable battery pack 128 provides approximately 324 kilojoules of energy and weighs approximately 0.82 kilograms. Therefore, the removable battery pack 128 includes an energy density of approximately 395 kilojoules per kilogram.
