The present disclosure relates to powered fastener drivers, and more specifically to lights for use with powered fastener drivers.
There are various fastener drivers known in the art for driving fasteners (e.g., nails, tacks, staples, etc.) into a workpiece. Occasionally, fastener drivers are used in confined spaces or other conditions where light is limited. It may be desirable for a user to see a nose piece of the fastener driver and the workpiece. Better illumination at the nose piece of the fastener driver greatly improves the ability to position a fastener with pinpoint accuracy. Known fastener driver lights can cast shadows that obstruct visibility of the nose piece over the work surface. Thus, a user has decreased ability to see where on the work surface the fastener will be inserted.
The present disclosure provides, in one aspect, a powered fastener driver. The powered fastener driver may include a driver blade, a lifter, a nose piece, a magazine, and a light. The driver blade is configured to be movable between a top-dead center position and a bottom-dead center position. The lifter is operable to move the driver blade from the bottom-dead center position toward the top-dead center position. The driver blade is extendable through the nose piece when moving from top-dead center to the bottom-dead center position. The magazine is configured to transfer individual fasteners into the nose piece, the magazine having a front side configured to face the workpiece during driving of the fastener, a rear side opposite the front side, and a lateral side. The light is positioned adjacent the lateral side of the magazine closer to the front side than the rear side.
The present disclosure provides, in another aspect, a powered fastener driver. The powered fastener driver may include a driver blade, a lifter, a nose piece, a magazine, and a light. The driver blade is configured to be movable between a top-dead center position and a bottom-dead center position. The lifter is operable to move the driver blade from the bottom-dead center portion toward the top-dead center position. The driver blade is extendable through the nose piece when moving from the top-dead center position to the bottom-dead center position. The magazine is configured to pass the fastener into alignment with the driver blade. The magazine has a front side configured to face the workpiece during driving of the fastener, an opposite rear side, and a lateral side extending between the front side and the rear side. The light is positioned adjacent the lateral side and the front side of the magazine. The light is configured to direct light toward the nose piece and the workpiece.

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 disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is 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.
With reference to
The illustrated fastener driver 10 may be a gas-spring powered fastener driver 10. Other similar pneumatic or otherwise powered fastener drivers 10 are possible. The gas spring powered fastener driver 10 may include a housing 42 within which the outer storage chamber cylinder 30 may be positioned.
The magazine 14 also includes a working side 14a (i.e., front side) closest to the working side 50a of the fastener driver 10 and an opposite distal side 14b (i.e., rear side) closest to the distal side 50b of the fastener driver 10. Accordingly, during use (e.g., driving of fastener[s]) of the fastener driver 10, the working side 14a (i.e., front side) of the magazine 14 may face at least the nose piece 76. In typical operation, the working side 14a (i.e., front side) of the magazine 14 will also face the work contact tip 76a and the workpiece W. However, other embodiments not including the work contact tip 76a are possible, and the geometry and dimensions workpiece W may differ. The working side 14a may be referred to as a front side of the magazine 14. The magazine 14 also includes a first lateral side 14c (i.e., a right side) and an opposite second lateral side 14d (i.e., a left side). The first lateral side 14c (i.e., the right side) of the magazine 14 is positioned adjacent to the first lateral side 50c (i.e., the right side) of the fastener driver 10. The second lateral side 14d (i.e., the left side) of the magazine 14 is positioned adjacent to the second lateral side 50d (i.e., the left side) of the fastener driver 10. The magazine 14 also includes a first end 14e (i.e., a top side) proximal to a lifting assembly 54 and an opposite second end 14f (i.e., a bottom side) adjacent the second vertical side 50f (i.e., the bottom side) of the fastener driver 10. The sides of the fastener driver 10 and magazine 14 are described in a single orientation relative to the workpiece W- with the working (i.e., front) sides thereof 50a, 14a facing the workpiece W. However, the fastener driver 10 and magazine 14 may be oriented in various orientations during normal use of the fastener driver 10.
With reference to
In operation, the lifting assembly 54 may drive the piston 22 and the driver blade 26 toward the TDC position by energizing the motor 58. As the piston 22 and the driver blade 26 are driven toward the TDC position, the gas above the piston 22 and the gas within the storage chamber cylinder 30 may be compressed. Prior to reaching the TDC position, the motor 58 may be deactivated and the piston 22 and the driver blade 26 are held in a ready position, which is located between the TDC and the BDC or driven positions, until being released by user activation of a trigger 66 (
With continued reference to
The controller 82 may be configured to operate (e.g., actuate, selectively dim, turn ON and OFF) a light 86a. In some embodiments (e.g.,
With continued reference to
With reference to
The main pusher 110 is more clearly illustrated in
Returning to the embodiment illustrated in
The light 86a is positioned at least partially in the compartment 42c adjacent the first lateral side (i.e., the right side) of the magazine 14. As mentioned above, the compartment 42c may be adjacent the second lateral side (i.e., the left side) of the magazine 14. The light 86a is capable of emitting light in a direction forward of the compartment 42c (i.e., through the transparent aforementioned light transparent window 42d). In a front-rear direction, the light 86a may be positioned closer to the working side 14a (i.e., front side) of the magazine 14 than the distal side 14b (i.e., rear side) of the magazine 14. In some embodiments, the light 86a may be positioned at least partially in-line with the working side 14a (i.e., front side) of the magazine 14. In other embodiments, the light 86a may be positioned between the working side 14a (i.e., front side) and the distal side 14b (i.e., rear side). As such, rays of light emitted by the light 86a reduce the size and amount of shadow(s) cast at an interface of where the fastener will enter the workpiece W as the fastener exits the nose piece 76. The aforementioned position of the light 86a is directly related to minimizing obstructions between the light 86a and a point at which the fastener will exit the nose piece 76.
With reference to
The controller 82, in turn, may actuate (e.g., turn ON and OFF) the light 86a based on the input from the dry fire lockout mechanism 98, the battery pack voltage sensor 126, and/or the auxiliary sensor 130. In the illustrated embodiment, the controller 82 may cycle the light 86a between an ON condition in which the light 86a emits rays of light and an OFF condition in which the light does not emit rays of light. In the ON condition, the rays of light shine upon the at least one of the nose piece 76 and the workpiece W. In the illustrated embodiment, a time that the light is on (e.g., ON TIME 134) and a time that the light is off (e.g., OFF TIME 138) are similar in response to each of the inputs from the dry fire lockout mechanism 98, the battery pack voltage sensor 126, and/or the auxiliary sensor 130. However, other arrangements in which the ON TIME 134 and the OFF TIME 138 are different are possible.
As illustrated in the Table below, the controller 82 may actuate the light 86a based on a variety of codes C1-C3. In other words, the controller 82 is programmed with a plurality of patterns for actuating the light 86a in response to any one of a plurality of events sensed by any of the dry fire lockout mechanism 98, the battery pack voltage sensor 126, and/or the auxiliary sensor 130. When the dry fire lockout mechanism 98 sends the signal to the controller 82, a code C3 is followed. The controller 82 receives the code C3 and actuates the light a blink count number BC3 in accordance with the code. The exemplary blink count BC3 is four. Blink count BC3 represents four cycles of the light 86a between the ON condition and the OFF condition. While cycling through the ON condition and the OFF condition, the ON TIME 134 and OFF TIME 138 of the code C3 are followed. In the illustrated embodiment, the ON TIME 134 and the OFF TIME 138 are each 200 milliseconds (ms). Other timings are possible. The battery pack voltage sensor 126, and/or the auxiliary sensor 130 operate along the same principles, but having differing blink counts (BC1-BC2) as well as different ON TIMEs 134 and OFF TIMEs 138 as enumerated in the Table below. The actual ON TIME 134 and OFF TIME 138 may be ±5% of the stated ON TIME 134 and OFF TIME 138 to allow for error in clock timing of the controller 82. Other amounts of clock timing error may are envisioned.
The aforementioned examples relating to actuation of the light 86a relate to instances (i.e., codes C1-C2) where the controller 82 may cause the fastener driver 10 not to cycle (e.g., fire) upon activation of the trigger 66. In other words, the aforementioned examples relate to actuation of the light 86a where the controller 82 inhibits driving of the driver blade 26 from its top-dead center position toward its bottom-dead center position. However, the controller 82 may actuate (e.g., turn ON and OFF) the light 86a based on any instance (i.e., code) in which the fastener driver 10 is still capable of cycling (e.g., firing) upon activation of the trigger 66. For example, other instances (i.e., codes) may include but are not limited to the fastener driver 10 being in an increased power level mode, a reduced power level mode, and the like. In the increased power level mode, for example, pressure within the storage chamber 31 may be above a desired pressure but less than an unsafe pressure. Instances other than raised pressure may also cause the fastener driver 10 to be placed in the increased power level mode. In the decreased power level mode, for example, pressure within the storage chamber 31 may be below a desired pressure but greater than an unusable pressure (at which fasteners may not enter the workpiece W to a desired depth). Instances other than lowered pressure may also cause the fastener driver 10 to be placed in the reduced power level mode. As such, the light 86a may notify the user about the mode in which the tool will operate by the flashes that the light 86a provides. In some instances, the actuation of the light 86a corresponding with when the fastener driver 10 is still capable of cycling (e.g., firing) may be initiated (e.g., started) upon activation of at least one or both of the nose piece 76 with the workpiece W and the trigger 66. In other instances, actuation of the light to indicate any instance (i.e., code) in which the fastener driver 10 is still capable of cycling (e.g., firing) may be initiated when the instance (e.g., raised or lowered pressure in the storage chamber 31) is sensed (e.g., by the auxiliary sensor 130). The light 86a may also be operated in modes corresponding with different types of usable but undesired values such as, without limitation, usable but not desired voltage supplied by the battery pack 75.
