1. Field of the Invention
The present disclosure generally relates to systems and methods related to an improved reciprocating saw. More particularly, the disclosure generally relates to systems and methods for a reciprocating saw which couples one or more workpieces to the reciprocating saw during use.
2. Description of the Relevant Art
Reciprocating saws typically incorporate reciprocating drive shafts for driving linear saw blades. The saw blades are driven along a predetermined path so as to provide a cutting action (e.g., either a rectilinear or an orbital motion). Efficient cutting with a reciprocating saw typically requires the workpiece to be secured in some fashion. Otherwise, the workpiece may move relative to the saw as a result of reciprocation of the saw blade. Securing the workpiece manually, by oneself or with an assistant, is not only problematic but also potentially dangerous.
In some embodiments, a system may include a reciprocating saw system. The reciprocating saw system may include a housing and a reciprocating blade. The reciprocating blade may be couplable to and extending from the housing. The system may include an elongated member. When activated the elongated member may move from a first position to a second position such that a workpiece is positioned adjacent at least a portion of the housing and the reciprocating blade. The system may include a tension mechanism coupled to the elongated member. When the tension mechanism is activated the elongated member may move from the first position to the second position. In some embodiments, the system may include an engaging mechanism. The engaging mechanism, when activated, releases a first stop positioned distally on the housing. The first stop may inhibit proximal movement of a conveyor coupled to the elongated member and a distal end of the tension mechanism. In some embodiments, when the first stop is released, when a tensile force is applied to the conveyor, the conveyor moves proximally moving the elongated member to the second position. In some embodiments, the system may include a loading mechanism. The loading mechanism may be coupled to a proximal end of the tension mechanism. The loading mechanism may be inhibited by a second stop when engaged from moving towards a distal end of the housing.
In some embodiments, when the second stop is disengaged the tensile force on the tension mechanism is released. In some embodiments, when the second stop is disengaged the tensile force on the tension mechanism is released such that the workpiece is released.
In some embodiments, the second stop is disengaged by manually applying pressure to a portion of the loading mechanism.
In some embodiments, the engaging mechanism is activated at a proximal end of the housing. In some embodiments, the engaging mechanism comprises a spring loaded elongated member moveable from a first position to a second position when activated.
In some embodiments, the elongated member comprises at least two elongated members positioned on opposing sides of the housing. In some embodiments, the elongated member may include a distal grasping portion which engages the workpiece during use. The elongated member may include a proximal portion which is curved such that when the elongated member moves from the first position to the second position the distal grasping portion moves up and back in a proximal direction.
In some embodiments, the system may include at least one track along which the conveyor and/or the loading mechanism are positionable.
In some embodiments, a method may include stabilizing a workpiece relative to a reciprocating saw system. The method may include activating a tension mechanism by applying a tensile force to the tension mechanism. The method may include inhibiting a loading mechanism, coupled to a proximal end of the tension mechanism, using a second stop when engaged from moving towards a distal end of the housing. The method may include activating an engaging mechanism to release a first stop positioned distally on the housing. The first stop may inhibit proximal movement of a conveyor coupled to the elongated member and a distal end of the tension mechanism. When the first stop is released, when a tensile force is applied to the conveyor, the conveyor may move proximally. The method may include moving an elongated member from a first position to a second position using the conveyor. The method may include positioning a workpiece, using the elongated member, adjacent at least a portion of a housing and a reciprocating blade. The reciprocating blade may be couplable to and extend from the housing.
Advantages of the present invention may become apparent to those skilled in the art with the benefit of the following detailed description of the preferred embodiments and upon reference to the accompanying drawings.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and may herein be described in detail. The drawings may not be to scale. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description. As used throughout this application, the word “may” is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). The words “include,” “including,” and “includes” indicate open-ended relationships and therefore mean including, but not limited to. Similarly, the words “have,” “having,” and “has” also indicated open-ended relationships, and thus mean having, but not limited to. The terms “first,” “second,” “third,” and so forth as used herein are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.) unless such an ordering is otherwise explicitly indicated. For example, a “third die electrically connected to the module substrate” does not preclude scenarios in which a “fourth die electrically connected to the module substrate” is connected prior to the third die, unless otherwise specified. Similarly, a “second” feature does not require that a “first” feature be implemented prior to the “second” feature, unless otherwise specified.
Various components may be described as “configured to” perform a task or tasks. In such contexts, “configured to” is a broad recitation generally meaning “having structure that” performs the task or tasks during operation. As such, the component can be configured to perform the task even when the component is not currently performing that task (e.g., a set of electrical conductors may be configured to electrically connect a module to another module, even when the two modules are not connected). In some contexts, “configured to” may be a broad recitation of structure generally meaning “having circuitry that” performs the task or tasks during operation. As such, the component can be configured to perform the task even when the component is not currently on. In general, the circuitry that forms the structure corresponding to “configured to” may include hardware circuits.
Various components may be described as performing a task or tasks, for convenience in the description. Such descriptions should be interpreted as including the phrase “configured to.” Reciting a component that is configured to perform one or more tasks is expressly intended not to invoke 35 U.S.C. §112, paragraph six, interpretation for that component.
The scope of the present disclosure includes any feature or combination of features disclosed herein (either explicitly or implicitly), or any generalization thereof, whether or not it mitigates any or all of the problems addressed herein. Accordingly, new claims may be formulated during prosecution of this application (or an application claiming priority thereto) to any such combination of features. In particular, with reference to the appended claims, features from dependent claims may be combined with those of the independent claims and features from respective independent claims may be combined in any appropriate manner and not merely in the specific combinations enumerated in the appended claims.
It is to be understood the present invention is not limited to particular devices or biological systems, which may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting. As used in this specification and the appended claims, the singular forms “a”, “an”, and “the” include singular and plural referents unless the content clearly dictates otherwise. Thus, for example, reference to “a linker” includes one or more linkers.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
The term “connected” as used herein generally refers to pieces which may be joined or linked together.
The term “coupled” as used herein generally refers to pieces which may be used operatively with each other, or joined or linked together, with or without one or more intervening members.
The term “directly” as used herein generally refers to one structure in physical contact with another structure, or, when used in reference to a procedure, means that one process affects another process or structure without the involvement of an intermediate step or component.
In some embodiments, a system may include a reciprocating saw system.
Reciprocating blades may include any number of different types of blades. For example, blades may function to cut wood, metal, glass, ceramic, etc. In some embodiments, the system may include other attachments besides a saw blade couplable to and extending from the housing. The system may include other attachments which function in a reciprocating manner. For example, the system may include an abrasive attachment such as a sanding attachment. In some embodiments, the system may include attachments which do not necessarily function in a reciprocating manner, for example, an elliptical motion, etc.
The loading mechanism may be inhibited by a second stop 320 when engaged from moving towards a distal end 320 of the housing. The second stop may include multiple stops 320a. Depressions 320b may mate with stops 320a when engaged. The loading mechanism may function to load tension on the tension mechanisms when used in combination with the conveyor. The loading mechanism when moved proximally and engaged to the second stop and the conveyor when moved distally and engaged to the first stop may apply tension to the tension mechanisms (e.g., as depicted in
In some embodiments, guides 250 may function to stabilize and/or guide elongated members as they are conveyed from one position to another. The guides may direct elongated members in one or more manners. For example the guides may keep the elongated members substantially parallel to the housing and/or at a predetermined angle relative to the housing (the angle may change depending upon the position of the elongated members relative to the housing. An orientation and/or angle of the elongated members relative to the housing may be adjusted based upon the angle of the guides relative to the housing. The angle of the guides relative to the housing may be adjustable. Openings in the guides through which elongated members travel may be angled to properly position and/or orient the elongated members relative to the housing. The angle of the guide and guide opening may function together to properly orient the elongated members relative to the housing.
In some embodiments, the tension mechanism 260 may include one or more springs. The tension mechanism may include two springs. The two springs may be positioned parallel to one another. In some embodiments, the tension mechanism may include one or more elastic bands. The elastic bands may be formed from a natural and/or synthetic material. The tension mechanism may include a material or mechanism with elastic properties.
In some embodiments, when the second stop is disengaged the tensile force on the tension mechanism is released. In some embodiments, when the second stop is disengaged the tensile force on the tension mechanism is released such that, for example, the workpiece is released (e.g., as depicted in
In some embodiments, the second stop is disengaged by manually applying pressure to a portion (e.g., a button or handle 330) of the loading mechanism. The portion of the loading mechanism may transfer the pressure/force to a portion of the stop such that the stop may disengage from the loading mechanism. Upon disengagement of the stop, tensile force on the tension mechanism may convey the loading mechanism towards the distal end of the housing releasing at least most of the tensile force on the tension mechanism. Releasing the tensile force may allow for disengagement of the elongated members, from for example a workpiece and/or allow for reloading the elongated members such that the elongated members may engage a workpiece (e.g., as depicted in
In some embodiments, the engaging mechanism is activated at a proximal end of the housing. In some embodiments, the engaging mechanism comprises an elongated member 340 movable from a first position to a second position when activated. In some embodiments, the engaging mechanism comprises a spring 350 loaded elongated member movable from a first position to a second position when activated. The spring may bias the elongated member in the first position or the second position. The spring may bias the elongated member in an unengaged position. The engaging mechanism when activated may apply pressure to the first stop such that the first stop disengages from the conveyor. The engaging mechanism may depress the first stop when the engaging mechanism is activated.
In some embodiments, the system may include at least two elongated members 230. In some embodiments, the elongated member comprises at least two elongated members 230a-b positioned on opposing sides of the housing 220. Elongated members positioned on either side of the housing may stabilize a workpiece relative to a single elongated member. In some embodiments, the elongated member 230 may include a distal grasping portion 370 which engages the workpiece during use. In some embodiments, the distal grasping portion may couple two elongated members positioned on either side of the housing. The elongated member may include a proximal portion 230c which is curved such that when the elongated member moves from the first position to the second position the distal grasping portion moves up and back in a proximal direction. The distal grasping portion may move up and back in a proximal direction to better grasp the workpiece and move it against the system attachment.
The distal grasping portion 370 may include a hooked portion which holds the workpiece against a saw blade or other system attachment. In some embodiments, the distal grasping portion may include different shapes configured for different uses. In some embodiments, the distal grasping portion may be couplable to the elongated member(s) such that the distal grasping portion may be coupled to or decoupled from the elongated member(s). Couplable distal grasping portions may include a set of differently shaped grasping portions which may be interchanged for different situations and uses.
In some embodiments, the distal grasping portion may be formed from one or more different materials. Materials may be chosen based upon the intended use of the grasping portion. In some embodiments, the grasping portion may include one or more coatings applied to at least a portion of the grasping portion. In some embodiments, materials and/or coatings may function to increase a coefficient of friction between the grasping member and the workpiece. Increasing the coefficient of friction may inhibit a workpiece from dislodging from the grasping members during use. In some embodiments, the grasping member may include a pattern and/or other three-dimensional surface permutations to increase a coefficient of friction between the grasping member and the workpiece. A coating may include a soft coating which helps to inhibit damage to the workpiece during use.
In some embodiments, the system may include one elongated member coupled to a distal grasping portion. The elongated portion may be positioned on a first side or an opposing second side. The distal grasping portion may extend substantially across the width of the distal end of the housing from the first side to the second side such that the grasping portion includes a greater surface area. The increased surface area of the grasping portion may function to stabilize the workpiece against a system attachment when the grasping portion engages the workpiece.
In some embodiments, the system may include at least one track along which the conveyor and/or the loading mechanism are positionable. In some embodiments, an outer assembly housing 380 may function to keep the conveyor and/or the loading mechanism in alignment. An assembly cover 390 may function to inhibit a conveyor from repositioning out of the assembly. In some embodiments, the conveyor may be sized and shaped in a complementary manner to an interior opening of the assembly housing such that the conveyor is inhibited from moving laterally as the conveyor moves longitudinally through the assembly housing. In some embodiments, at least a first portion of the loading mechanism may be positionable within the assembly housing such that the loading mechanism is inhibited from moving laterally as the conveyor moves longitudinally through the assembly housing. In some embodiments, an elongated opening 400, through which the first portion is coupled to a second portion of the loading mechanism, function to inhibit lateral and/or longitudinal movement of the loading mechanism while being conveyed along the assembly housing.
