The present invention relates to an abutment device, and more particularly to an abutment device of a nail gun disposed on a bottom side of a nail cartridge of a nail gun, and a technique for positioning, releasing and adjusting a displacement of an abutment device of a nail gun.
A pneumatic driven nail gun is a high pressure air driven tool for shooting nails on a workpiece. It has been widely used in nailing jobs on daily items, furniture, buildings and etc.
To nail multiple wood boards or shingles with a conventional nail gun, an operator may align nailing positions on the multiple wood boards or shingles in accordance with a single straight line by eye measurement, or alternatively, the operator may measure and mark a straight line on the multiple wood boards or shingles and then shoot nails thereupon with the nail gun along the marked straight line. However, by eye measurement as mentioned above, it is difficult to ensure all the nails are positioned along a perfectly straight line. In addition, measuring and marking a straight line on multiple wood boards or shingles may slow down the speed of overall operation and prolong the overall operation time.
To overcome the above disadvantages, a user may position a protruding structure on a bottom of an nail cartridge of the nail gun such as a protruding block or a side board close to sides of the multiple wood boards or shingles one after another so as to align the nailing position to straight line. The problem with this approach is, however, the position of this protruding structure is generally difficult to adjust. So it is desired to solve this problem.
To overcome the disadvantages of the prior art described above, the present invention provides an abutment adjusting device for a nail gun, which can be used to position an abutment device of a nail gun close to side ends of the multiple wood boards or shingles one by one and use the nail gun to shoot nails thereupon in an aligned straight line. In addition, the alignment position can be adjusted freely and hence the convenience of using the nail gun is improved.
To achieve the above mentioned objective, the abutment adjusting device for a nail gun that the present invention provides includes:
a horizontal sliding rail disposed on a bottom side of an nail cartridge of the nail gun, the sliding rail having a horizontal guiding board on each side thereof, a plurality of positioning grooves opening downward being disposed between the guiding boards;
an abutment having a containing groove opening upward, the containing groove having two groove sidewalls, each of the sidewalls having a horizontal groove and at least a vertical guiding channel, the horizontal grooves being mounted on the guiding board for guiding the abutment to be slidably disposed on the sliding rail;
a sliding block with a top having at least a protruding part corresponding to the positioning grooves, the two sides of the sliding block respectively having at least a vertical ear-board, each ear-board is slidably disposed in the guiding channel for guiding the sliding block to be slidably disposed in the containing groove; and
a first elastic unit disposed in the containing groove for driving the sliding block to move upward and further drive the protruding part to be engaged into the positioning grooves so as to position the abutment.
With the present invention, by positioning the abutment close to the sides of the multiple wood boards or shingles one by one, a user can use the nail gun to shot nails thereon in an aligned straight line. In addition, the user can press the sliding block to drive the protruding part to be disengaged from the positioning groove, move the abutment to an appropriate position and release the sliding block to drive the protruding part to be engaged with the positioning groove and to position the abutment for another time so as to improve the speed of nailing and reduce the operating time.
The sliding block can further have a contact part naked on an outside of the abutment on a side end of the sliding block.
In another aspect, the abutment adjusting device for a nail gun of the present invention could include:
a horizontal sliding rail disposed on a bottom side of an nail cartridge of the nail gun, the sliding rail having a horizontal guiding board on each side thereof, a plurality of positioning grooves opening downward being disposed between the guiding boards;
an abutment having a containing groove opening upward, the containing groove having two groove sidewalls, each of the sidewalls having a horizontal groove and at least a vertical guiding channel, the horizontal grooves being mounted on the guiding board for guiding the abutment to be slidably disposed on the sliding rail;
a sliding block with a top having at least a protruding part corresponding to the positioning grooves, the two sides of the sliding block respectively having at least a vertical ear-board, each ear-board is slidably disposed in the guiding channel for guiding the sliding block to be slidably disposed in the containing groove, the sliding block having a tilted guiding groove installed on a side end thereof;
a button horizontally and slidably disposed in the containing groove, the button having a tiled shape and being engaged with a guiding piece in the guiding groove, the button being configured for driving the sliding block moving vertically so as to drive the protruding part to be engaged with or disengaged from the positioning groove; and
at least a second elastic unit disposed in the containing groove and configured for driving the button to move and further drive the protruding part to be engaged with the positioning groove so as to position the abutment.
With the present invention, by positioning the abutment close to the sides of the multiple wood boards or shingles one by one, a user can use the nail gun to shot nails thereon in an aligned straight line. In addition, the user can press the button to drive the protruding part to be disengaged from the positioning groove and to release the abutment and can release the button to drive the protruding part to be engaged with the positioning groove and to position the abutment for another time.
The button can further have a contact part naked on an outside of the abutment on a side end of the button.
Furthermore, a protection board can be mounted to the abutment for preventing wearing on bottom and sides of the abutment.
These and other features and advantages of the various embodiments disclosed herein will be better understood with respect to the following description and drawings, in which like numbers refer to like parts throughout, and in which:

When a user intends to shoot nails upon multiple wood boards or shingles 8 patterned in a scale shape, as shown in
When a user intends to nail on multiple wood boards or shingles 8 of different sizes patterned in a scale shape, the user can repeat releasing, adjusting and positioning the abutment 3 as mentioned above to horizontally move the abutment 3 along the sliding rail 2 to another appropriate position so as to align the nailing position of the nail gun 1 on multiple wood boards or shingles 8 of different sizes. Hereby, by positioning the abutment 3 close to the tops 81 and the sides 82 of the multiple wood boards or shingles 8 one by one, the user can use the nail gun 1 to shoot nails thereupon in an aligned straight line. In addition, the user can adjust the aligned position freely, which improves the convenience of using the nail gun 1.
This way, referring to
In summary, it is known in the present invention a sliding rail 2 is disposed on a bottom side of a nail cartridge 11 of a nail gun 1. An abutment 3 designed to have positioning, releasing and displacement adjustment functions is slidably disposed on the sliding rail 2. When the nail gun 1 is used to shoot nails on multiple wood boards or shingles 8 of different sizes patterned in a scale shape, the speed of such operation is improved and the working time thereof is reduced.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including configurations ways of the recessed portions and materials and/or designs of the attaching structures. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein.
