1. Field of the Invention
The present invention relates to a nail or fastener driver, and more particularly to a washer assembly for a nail or fastener driver including a number of washer members coupled or superposed or stacked together for allowing the washer members to be suitably and easily and quickly and readily fed or introduced or moved or engaged into the washer holding and carrying and feeding device of the fastener driver by the user.
2. Description of the Prior Art
Typical staplers or nail or fastener drivers or driving machines comprise a magazine attached or mounted or secured to a lower or bottom portion of a driving machine body for receiving or accommodating a number of nails or fasteners, and an ejector or hammering or driving mechanism attached or mounted or secured to a front portion of the driving machine body for hammering or driving the nails or fasteners into work pieces.
For preventing the nails or fasteners from being deeply hammered or driven or engaged into the work pieces, some of the typical staplers or nail or fastener drivers or driving machines have been developed to provide a washer holding and carrying and feeding device for receiving or accommodating a number of washers and for feeding or supplying the washers toward the nose section of the fastener driver and for allowing the washers to be engaged with the nails or fasteners that are hammered or driven by the ejector or driving mechanism.
For example, U.S. Pat. No. 6,471,107 to Liu et al., U.S. Pat. No. 6,481,610 to Liu et al., and U.S. Pat. No. 6,908,022 to Schmitz disclose several of the typical staplers or nail or fastener drivers or driving machines each also comprising a washer holding and carrying and feeding device for receiving or accommodating a number of washers and for feeding or supplying the washers toward the nose section of the fastener driver and for allowing the washers to be engaged with the nails or fasteners that are hammered or driven by the ejector or driving mechanism.
However, the washers have not been coupled or superposed or stacked together such that the washers may not be easily and quickly and readily fed or introduced or moved or engaged into the washer holding and carrying and feeding device of the fastener driver by the user.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional washer holding and carrying and feeding devices for fastener drivers.
The primary objective of the present invention is to provide a washer assembly for a nail or fastener driver including a number of washer members coupled or superposed or stacked together for allowing the washer members to be suitably and easily and quickly and readily fed or introduced or moved or engaged into the washer holding and carrying and feeding device of the fastener driver by the user.
In accordance with one aspect of the invention, there is provided a washer assembly for a fastener driver comprising a layer including a number of washer members coupled together and located side by side, and including a hinge line formed between every two adjacent washer members for temporarily securing the washer members together, and including an orifice formed in each of the washer members for selectively receiving or engaging with the nails or staples or fasteners that are hammered or punched or driven or moved out of the nose portion of the driver body member by the ejector.
The layer includes an elongate strap attached to the washer members for solidly or stably coupling the washer members together and also for allowing the washer members to be cut or separated from each other when the washer member is engaged with the nails or staples or fasteners that are hammered or punched or driven or moved out of the nose portion of the driver body member by the ejector.
The washer members each include a first notch formed in one side portion thereof, and a second notch formed in an opposite side portion thereof for temporarily securing or coupling the washer members together.
The washer members each include a recess formed therein and communicative with the orifice of the washer member for reducing a thickness of the washer member around the orifice of the washer member.
One or more further layers may further be provided and each include a number of second washer members coupled together and located side by side, and each include a hinge line formed between every two adjacent second washer members for temporarily securing the second washer members together, and each include an orifice formed in each of the second washer members.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
In operation, the trigger 14 may be pulled or operated or actuated by the user to actuate or operate or force a driver bit or shaft (not shown) to hammer or strike or push or force the nails or staples or fasteners out through the nose portion 13 of the driver body member 10. The staple or fastener driver 1 further comprises a washer holding and carrying and feeding device 15 attached or mounted or secured or coupled to the driver body member 10 and/or the cassette 12 for receiving or holding or carrying or accommodating the washer members 31 of a washer assembly 3 in accordance with the present invention (
The above-described structure or configuration for the driver body member 10 and the cassette 12 is typical and is not related to the present invention, and the washer holding and carrying and feeding device 15 is also not related to the present invention and will not be described in further details. As shown in
The washer members 31 of the layers 30 of the washer assembly 3 each include an orifice 33 formed therein, such as formed in the center portion thereof for selectively receiving or engaging with the nails or staples or fasteners that are hammered or punched or driven or moved out of the nose portion 13 of the driver body member 10 by the ejector (not shown). As also shown in
Accordingly, the rods or poles 9 may be provided for engaging through the orifices 33 of the washer members 31 and for organizing the washer members 31 of the layers 30 of the washer assembly 3 and for easily and quickly moving or engaging the washer members 31 into the washer holding and carrying and feeding device 15 of the fastener driver 1. However, the engagement of the rods or poles 9 with the orifices 33 of the washer members 31 of the layers 30 of the washer assembly 3 and for organizing the washer members 31 of the layers 30 of the washer assembly 3 has been filed in a co-pending patent application, and will not be described in further details.
As shown in
It is preferable that the washer members 31 of the layers 30 of the washer assembly 3 each include a first depression or notch 34 formed in one side portion 35 thereof, and another or second depression or notch 36 formed in other or opposite side portion 37 thereof for reducing the cutting or hinge lines 32 and for allowing the washer members 31 to be separated from each other much easier. An elongate strap 40 may further be provided and attached or mounted or secured to the bottom portion of the washer members 31 for further solidly and stably attaching or mounting or securing or coupling the washer members 31 together. The elongate strap 40 may be made of rubber or plastic materials and arranged for allowing the elongate strap 40 to be easily broken or cut together with the washer member 31 when the washer member 31 is hammered or punched or driven or engaged with the nail or staple or fastener. The elongate strap 40 may also be removed from the washer members 31 selectively and optionally (
As shown in
In operation, one of the layers 30 of the washer assembly 3, particularly the layer 30 that is located farther away from the driver body member 10 and the cassette 12 and the handle 11 will be moved or pushed forwardly toward the nose portion 13 of the driver body member 10 by the pusher device 17 (
Accordingly, the washer assembly for the nail or fastener driver in accordance with the present invention includes a number of washer members coupled or superposed or stacked together for allowing the washer members to be suitably and easily and quickly and readily fed or introduced or moved or engaged into the washer holding and carrying and feeding device of the fastener driver by the user.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
