The present disclosure relates to abrasive tools, and more particularly to battery powered angle grinders.
Angle grinders are standard tools in most machine shops. Depending on the application, angled grinders may be used with thin cut-off discs, abrasive discs, sanding discs, wire brushes, etc. in order to cut a workpiece, grind a workpiece, sand a workpiece, or clean a workpiece (e.g., with a brush).
The present disclosure provides, in one aspect, an angle grinder includes a housing, a motor within the housing, a gearcase extending from the housing, wherein the gearcase includes a spindle and the spindle is driven by the motor, a rotating tool removable engaged with the spindle, a flange removably engaged with the spindle to secure the rotating tool on the spindle, and a flange retainer disposed on the grinder, wherein the flange retainer is configured to receive and retain the flange when the flange is disengaged from the spindle.
The present disclosure provides, in another aspect, an angle grinder includes a housing, a motor within the housing, a gearcase extending from the housing, wherein the gearcase includes a spindle and the spindle is driven by the motor, a rotating tool removable engaged with the spindle, a flange removably engaged with the spindle to secure the rotating tool on the spindle, and a flange retainer disposed on the grinder, wherein the flange retainer is a generally U-shaped spring clip that receives and retains the flange when the flange is disengaged from the spindle.
The present disclosure provides, in still another aspect, an angle grinder having a housing, a motor within the housing, a gearcase extending from the housing, wherein the gearcase includes a spindle and the spindle is driven by the motor, a rotating tool removable engaged with the spindle, a guard mounted on the gearcase and at least partially surrounds the rotating tool, a flange removably engaged with the spindle to secure the rotating tool on the spindle, and a flange retainer disposed on the guard, wherein the flange retainer is configured to receive and retain the flange when the flange is disengaged from the spindle.
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.
Features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents. The detailed description uses numerical and letter designations to refer to features in the drawings. Like or similar designations in the drawings and description have been used to refer to like or similar parts of the invention.
As used herein, the terms “first”, “second”, and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. The terms “coupled,” “fixed,” “attached to,” and the like refer to both direct coupling, fixing, or attaching, as well as indirect coupling, fixing, or attaching through one or more intermediate components or features, unless otherwise specified herein. As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive- or and not to an exclusive- or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Terms of approximation, such as “generally,” “approximately,” or “substantially,” include values within ten percent greater or less than the stated value. When used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction. For example, “generally vertical” includes directions within ten degrees of vertical in any direction, e.g., clockwise or counter-clockwise.
Benefits, other advantages, and solutions to problems are described below with regard to specific embodiments. However, the benefits, advantages, solutions to problems, and any feature(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential feature of any or all the claims.
Referring to
During operation, a user can grip the housing 102 of the angle grinder 100 and the housing 102 can act as a primary handle. To provide greater stability against torsional forces during use, the angle grinder 100 may include a side handle 120 (e.g., acting as a secondary handle) that is removably engaged with the gearcase 112. In a particular embodiment, the gearcase 112 includes a first handle attachment point 122 on a first side of the gearcase 112 and a second handle attachment point 124 on a second side of the gearcase 112 that is disposed opposite the first side. The handle attachment points 122, 124 may be formed with internal threads that are sized and shaped to engage corresponding male threads formed on a threaded shaft (not shown) that extends from an end of the handle 120. As shown in
With continued reference to
During use, the arms 134, 136 of the flange retainer 130 may be squeezed toward each other to reduce the distance between the undulations formed on the arms 134, 136. When released, the springiness of the arms 134, 136 may bias the arms 134, 136 away from each other and return the arms 134, 136 to the starting position. As shown, the flanges 138, 140 can be fitted over the arms 134, 136 of the flange retainer 130 and the outward spring force of the arms 134, 136, in conjunction with the undulations formed on the arms 134, 136, may retain the flanges 138, 140 on the flange retainer 130 until they are needed to hold the rotating tool 116 in place on the spindle 114 of the gearcase 112.
During use, the arms 534, 536 of the flange retainer 530 may be flexed away from each other to increase the distance between the undulations formed on the arms 534, 536. When released, the springiness of the arms 534, 536 may bias the arms 534, 536 toward each other back to the starting position. As shown, the flanges 538, 540 can be fitted between the arms 534, 536 of the flange retainer 530 and the inward spring force of the arms 534, 536, in conjunction with the undulations formed on the arms 534, 536, may retain the flanges 538, 540 on the flange retainer 530 until they are needed to hold the rotating tool 516 in place on the spindle 514 of the gearcase 512.
It is to be understood that in any of the aforementioned embodiments, the flange retainer may include a spring clip, a magnet, a pocket, or any combination thereof.
As described above, some or all illustrated features may be omitted in a particular implementation within the scope of the present disclosure, and some illustrated features may not be required for implementation of all embodiments. The features described above may be implemented in an order different from the order described above and does not prohibit implementation in another order or combination. While not explained in detail for each embodiment and/or construction, the features of the disclosure described herein may be included on a tape dispenser independent of other features and are not limited to the illustrated disclosure.
