Definitions

  • the present disclosure relates to fastener driving apparatuses, and, more particularly, to such fastener or staple driving mechanisms that require operation as a hand tool.
  • Electromechanical fastener driving apparatuses also referred to herein as a "driver,” “gun” or “device" known in the art often weigh generally less than 15 pounds and may be configured for an entirely portable operation.
  • These power-assisted means of driving fasteners can be either in the form of finishing fastener systems used in baseboards or crown molding in house and household projects, or in the form of common fastener systems that are used to make walls or hang sheathing onto same.
  • These systems can be portable (i.e., not connected or tethered to an air compressor or wall outlet) or non-portable.
  • the most common fastener driving apparatus uses a source of compressed air to actuate a guide assembly to push a fastener into a substrate.
  • this is a very functional system and allows rapid delivery of fasteners for quick assembly.
  • a disadvantage is that it does however require that the user purchase an air compressor and associated air-lines in order to use this system.
  • a further disadvantage is the inconvenience of the device being tethered (through an air hose) to an air compressor.
  • FIG. 1 Another commercially available solution is a fastener gun that uses electrical energy to drive a stapler or wire brad.
  • Such units typically use a solenoid to drive the fastener (such as those commercially available under the ArrowTM name or those which use a ratcheting spring system such as the RyobiTM electric stapler).
  • These units are limited to short fasteners (typically 1" or less), are subject to high reactionary forces on the user and are limited in their repetition rate. The high reactionary force is a consequence of the comparatively long time it takes to drive the fastener into the substrate.
  • the ability to drive longer fasteners or larger fasteners is severely restricted, thus relegating these devices to a limited range of applications.
  • a further disadvantage of the solenoid driven units is they often must be plugged into the wall in order to have enough voltage to create the force needed to drive even short fasteners.
  • a final commercially available solution is to use a flywheel mechanism and clutch the flywheel to an anvil that drives the fastener.
  • Examples of such tools can be found under the DewaltTM name. This tool is capable of driving the fasteners very quickly and in the longer sizes.
  • the primary drawback to such a tool is the large weight and size as compared to the pneumatic counterpart. Additionally, the drive mechanism is very complicated, which gives a high retail cost in comparison to the pneumatic fastener gun.
  • the first technique is based on a multiple impact design.
  • a motor or other power source is connected to an impact anvil through either a lost motion coupling or other device. This allows the power source to make multiple impacts on the fastener to drive it into the workpiece.
  • the disadvantages in this design include increased operator fatigue since the actuation technique is a series of blows rather than a single drive motion.
  • a further disadvantage is that this technique requires the use of an energy absorbing mechanism once the fastener is seated. This is needed to prevent the anvil from causing excessive damage to the substrate as it seats the fastener.
  • the multiple impact designs are not very efficient because of the constant motion reversal and the limited operator production speed.
  • 172, 121 includes the use of potential energy storage mechanisms (in the form of a mechanical spring).
  • the spring is cocked (or activated) through an electric motor. Once the spring is sufficiently compressed, the energy is released from the spring into the anvil (or fastener driving piece), thus pushing the fastener into the substrate.
  • drawbacks exist to this design include the need for a complex system of compressing and controlling the spring, and in order to store sufficient energy, the spring must be very heavy and bulky. Additionally, the spring suffers from fatigue, which gives the tool a very short life. Finally, metal springs must move a significant amount of mass in order to decompress, and the result is that these low-speed fastener drivers result in a high reactionary force on the user.
  • a further disadvantage presented is that the fastener must be fed once the anvil clears the fastener on the backward stroke. The amount of time to feed the fastener is limited and can result in jams and poor operation, especially with longer fasteners.
  • a further disadvantage to the air spring results from the need to have the ratcheting mechanism as part of the anvil drive. This mechanism adds weight and causes significant problems in controlling the fastener drive since the weight must be stopped at the end of the stroke. This added mass slows the fastener drive stroke and increases the reactionary force on the operator. Additionally, because significant kinetic energy is contained within the air spring and piston assembly the unit suffers from poor efficiency. This design is further subject to a complicated drive system for coupling and uncoupling the air spring and ratchet from the drive train which increases the production cost and reduces the system reliability.
  • US Patent No. 5,720,423 again teaches of an air spring that is compressed and then released to drive the fastener.
  • the drive or compression mechanism used in this device is limited in stroke and thus is limited in the amount of energy which can be stored into the air stream.
  • this patent teaches use of a gas supply which preloads the guide assembly at a pressure higher than atmospheric pressure.
  • the compression mechanism is bulky and complicated.
  • the timing of the motor is complicated by the small amount of time between the release of the piston and anvil assembly from the drive mechanism and its subsequent re-engagement.
  • US Patent No, 5,720,423 teaches that the anvil begins in the retracted position, which further complicates and increases the size of the drive mechanism. Furthermore, because of the method of activation, these types of mechanisms as described in US Patent Nos. 5,720,423 and 4,215,808 must compress the air to full energy and then release off the tip of the gear while under full load. This method of compression and release causes severe mechanism wear. As will be discussed below, the present disclosure overcomes these and other limitations in the prior art use of air springs.
  • a third means for driving a fastener includes the use of flywheels as energy storage means.
  • the flywheels are used to a hammering anvil that impacts the fastener.
  • This design is described in detail in US Patent Nos. 4,042,036, 5,511,715, and 5,320,270.
  • One major drawback to this design is the problem of coupling the flywheel to the driving anvil.
  • This prior art teaches the use of a friction clutching mechanism that is both complicated, heavy and subject to wear. Further limiting this approach is the difficulty in controlling the energy in the fastener system. The mechanism requires enough energy to drive the fastener, but retains significant energy in the flywheel after the drive is complete. This further increases the design complexity and size of such prior art devices.
  • Patent No. 8,079,504 which uses a compression on demand system with a magnetic detent.
  • This system overcomes many of the advantages of the previous systems but still has its own set of disadvantages which include the need to retain a very high pressure for a short period of time. This pressure and subsequent force necessitate the use of high strength components and more expensive batteries and motors.
  • the fuel powered mechanisms have loud combustion reports and combustion fumes.
  • the multiple impact devices are fatiguing and are noisy.
  • a fastener driving apparatus which derives its power from an electrical source, preferably rechargeable batteries, and uses a motor to actuate a spring (such as a gas spring, for example).
  • a spring such as a gas spring, for example.
  • the piston of the gas spring commences movement, accelerating an anvil and/or anvil assembly.
  • the anvil assembly preferably has a mass that is greater than the weight of the piston, the contact of the piston with the anvil causes the anvil to move.
  • the piston comes to rest on a bumper but the anvil assembly continues to move toward and into contact with a fastener such that the anvil drives the fastener.
  • the effective mass differential between the piston and the anvil facilitates sufficient energy being transferred to the anvil for driving a fastener.
  • a return spring or other return mechanism is incorporated to return the anvil, after the anvil drives the fastener, to a position where the anvil and/or anvil assembly may again be operatively contacted by the piston for another drive by the anvil.
  • test results show conversion efficiencies (potential energy to kinetic energy in the drive anvil) of over 80%, which is far better than the 65% obtained by the apparatus of the '504 patent.
  • the fastener driving cycle of the apparatus disclosed herein may start with an electrical signal, after which a circuit connects a motor to the electrical power source.
  • the motor is coupled to the gas spring through a drive mechanism.
  • the mechanism alternatively (1) actuates the piston of the gas spring and (2) decouples from the piston.
  • the drive mechanism may move the piston to increase potential energy stored within the gas spring.
  • the mechanism decouples from the piston to allow the accumulated potential energy within the gas spring to act on and actuate the piston.
  • the piston thereupon moves and causes the anvil assembly to move and drive a fastener.
  • a spring or other return mechanism is operatively coupled to the anvil and anvil assembly to return the anvil to an initial position.
  • at least one bumper is disposed within the gas spring or outside the gas spring to reduce the wear on the piston.
  • another bumper is used to reduce the wear on the anvil assembly that otherwise may occur in operation of the fastener driving apparatus.
  • the mass of the anvil and anvil assembly is at least equal to the moving mass of the gas spring, and more preferably, at least 1.2 times the moving mass of the gas spring.
  • the stroke or movement of the piston is less than one half the total movement of the anvil and anvil assembly. Further preferred is that the movement of the piston results in a volume decrease within the gas spring of less than 20% of the initial volume (which thus reduces losses from heat of compression.)
  • a sensor and a control circuit are provided for determining at least one position of the anvil, anvil assembly, and/or drive mechanism to enable the proper timing for stopping the operational cycle of the apparatus. Further, this information can be used to detect a j am condition for proper recovery.
  • the piston launches the anvil and/or anvil assembly prior to or within less than 20% of the total fastener stroke. This results in an improved safety profile in the event of a jam, as the anvil and anvil assembly will have dissipated its kinetic energy, thus allowing the user to fix the jam without having potential energy remaining in the anvil and anvil assembly.

  • the drive mechanism 50 preferably acts directly upon the anvil assembly 60, which anvil assembly 60 is at least operatively coupled to and moves the piston 42 to store potential energy (as described elsewhere herein.)

Abstract

L'invention concerne un appareil d'enfoncement de pièce de fixation comportant un ressort à gaz ou un ressort, un mécanisme d'entraînement, un ensemble d'enclume, et une enclume. Le mécanisme d'entraînement permet la transition depuis la mise en prise avec le ressort à gaz, le ressort ou l'ensemble d'enclume à la désolidarisation du ressort à gaz, du ressort ou de l'ensemble d'enclume. L'enclume et/ou de l'ensemble d'enclume sont accouplés de manière fonctionnelle au ressort à gaz ou au ressort de telle sorte que, une fois que le mécanisme d'entraînement s'est désolidarisé par rapport à ceux-ci, le piston du ressort à gaz ou du ressort se déplace afin de conférer une force sur l'enclume pour amener l'enclume à se déplacer et à entraîner une pièce de fixation. La masse de l'ensemble d'enclume est de préférence supérieure à 50 % de la masse totale de l'ensemble d'enclume et du ressort à gaz déplaçant une masse. Le ressort à gaz est configuré de telle manière que l'augmentation de pression au cours du mouvement du piston du ressort à gaz par le mécanisme d'entraînement est inférieure à 30 % de la pression initiale dans le ressort à gaz.
