Patent Application
20120009044
The present invention relates to coil nails, and more particularly, to an auxiliary member for assisting the last nail to successfully enter the passage of the nail gun.
The conventional coil nails is shown in
The coil nails is installed in the magazine (not shown) of a nail gun and the head 40 of the first nail 4 is installed into the slide groove 101 of the connection part 10 of the nail gun and the first nail 4 is pushed left as shown in the drawings until the first nail 4 enters into the passage 11 of the nose 1 of the nail gun. The shank 41 of the second nail 4 is arranged on the main pusher 20 of the push mechanism 2 and the rest of the nails 4 are located in the connection part 10 and the magazine. The cover 15 is then covered on the connection part 10 of the nose 1 and the sub-pusher 16 on the cover 15 is located on the right side of the shank 41 of the second nail 4. The nails 4 are located between the cover 15 and the connection part 10 and are ready to shoot.
When pulling the trigger, the strike pin (not shown) moves fast to shoot the nail 4 in the passage 11 in the nose 1 and the strike pin returns to initial position and ready for the next shoot. The push mechanism 2 is controlled to move toward right, however, the shank 41 of the second nail 4 is stopped by the sub-pusher 16 of the cover 15, so that the main pusher 20 is forced to move over the shank 41 of the second nail 4 and is located beside the shank 41′ of the third nail 4′. Finally, the main pusher 20 of the push mechanism 2 pushes the third nail 4′ toward left to force the shank 41′ of the third nail 4′ pushes the sub-pusher 16 inward and the sub-pusher 16 returns to its original position after the shank 41′ of the third nail 4′ passes. The actions are repeated until only the last nail 4 is in the nail gun. When the last nail 4 enters into the passage 11 which is perpendicular to the ground, the last nail 4 does not have any holding force to hold it so that the last nail 4 easily drops from the passage 11. This means that the last nail 4 is useless and wasted.
The present invention intends to provide an auxiliary member for coil nails wherein the last nail can be successfully sent to the right position to be shot.
The present invention relates to an auxiliary member which includes a shank and a connection portion which is connected to the lateral side of the shank by a extension portion which is not parallel to the shank. The connection portion holds the last nail of the coil nails to ensure that the last nail is correctly sent to eh passage of the nail gun.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
When in use, the strike pin 75 moves fast to shoot the nail 80 in the passage 71 in the nose 7 and the strike pin 75 then returns to initial position and ready for the next shoot as shown in
An extension portion 55 is connected at a lateral side of the shank 50 and the shank 50 and the extension portion 51 are non-parallel to each other. A connection portion 52 is connected to a distal end of the extension portion 51 and the connection portion 52 holds the last nail 89 of the coil nails which are connected by the connection members 85. The distance between the shank 50 and the connection portion 52 is multiple times of a distance between two adjacent nails 80, 81 such that the main pusher 60 of the push mechanism 6 can catch the nails 80, 81. Besides, the connection portion 52 can be an opened curved surface, a flat surface or a hollow cylinder, so that the connection portion 52 is able to hold, mount to or adhered to the shank 890 of the last nail 89.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
