Description
llAND-llELD I;RAMINC, TOOL
BACKGROUND OF TllE INVENTION
1. [field of the Invention
The present invention relates generally to hand-held tools, and more particularly to a hand-held framing tool for inserting nails into picture frames or the like.
2. Description of the Related Art
As shown in I*IG. 1, while making a picture frame regularly, a V-shaped nail C is inserted into between two adjacent frame bars A and B by a handheld framing tool.
A conventional hand-held framing too], as disclosed in U. S. Patent No. 6, 220,121, includes a tool body, an anvil head, and means for retaining fasteners. The retaining means is a magnet to hold the V-shaped nail at a front end thereof. While the framing tool is punched to drive the nail to contact against the two frame bars of the picture frame, the retaining means will retract in the anvil head and against biasing means to permit the anvil head to drive the nail into the frame's surface, thereby securing the two frame bars of the t'rame.
I lowever, there are some drawbacks for the aforementioned conventional framing tool. The retaining means holds the nail merely by magnetism thereof without any other retaining force such that while the framing tool is held not vertical to the frame or the nail is positioned beveledly, the nail may be squashed on the surface of the frame even projected outwards to hurt someone rather than inserted into the frame.
SUMMARY OF TIlE INVENTION
The primary objective of the present invention is to provide a hand-held framing tool, which is structurally simple, and easy and safe for operation.
I he foregoing objective of the present invention is attained by the handheld framing tool, Which iS c-,mposcd of a handle, a cover shell, and a guide mcmtcr. Tl1c handle includes a coupling portion at an end thereof and a bar member protruded outwards from the coupling portion and fitted with a spring. T he cover shell includes a chamber insitle at a front end thereof and a guide hole positioned at a bottom side of the chamber, running through a rear end thereof, c-nnmunicating with the chamber, and having a smaller inner diameter than the chamber. he cover shell is connected with the coupling portion of the handle. The bar member has a distal end extended slightly out of the cover shell. The guide member is an elongated tube member and includes a stopping portion at an end thereof and a plurality of guide ditches extended longitudinally along an inner periphery thereof: The guide member is fitecd in the guide hole of the cover shell and the bar member of the handle runs through a hollow space thereof, so as to receive the bar member inside. The spring contacts against the stopping portion of the guide member at an end thereof and contacts against the coupling portion of the handle at the other end thereof.

I is a schematic view of a picture frame where V-shaped nails are inserted; FIG. 2 is an elevational view of a preferred embodiment of the present invention; FIG. 3 is a bottom view of the preferred embodiment of the present invention; FIG. 4 is a partial sectional view of the preferred embodiment ol the present invention; FIG. 5 is a partial sectional view of the preferred embodiment of the present invention showing that a nail is held by the guide member; and FIG. 6 is a partial sectional view of the pret'erred embodiment of the present invention showing that the nail is punched into the frame.
DIITAILED DESCRIPTION OF TIIE INVENTION
Referring to T;IGS. 3-4, a hand-held *aiming tool of the present invention is composed of a handle 4(), a cover shell 50, and a guide member 60.
The handle 40 is cylindrical and includes a convex portion 41 at an end thereof and a coupling portion 42 at the other end thereof. The coupling portion 42 is provided with a thread 43 at an outer periphery thereof and a bar member 44 protruded outwards from the coupling portion 42. The bar member 44 is fitted with a spring 45 and is provided with a magnet 46 at a free end thereof.
The cover shell 50 is taper-]ike, including a wide end where a chamber S l is formed inside, a thin end where a guide hole 52 is formed and positioned at a bottom side of the chamber 51, and a stepped portion 54 formed between the chamber 51 and the guide hole 52. The guide hole 52 has a smaller inner diameter than the chamber 51 and communicates with the chamber 51 and runs through the thin end of the cover shell 50. The cover shell 50 is further provided with a thread 53 at an inner periphery of the chamber 51 in proximity of the wide end of the chamber 51 for comlecting the coupling portion 42 of the handle 40, such that the bar member 44 of the handle 40 is protruded slightly out of the thin end of the cover shell 50 at a distal end thereof.
Tlle guide member 60 is an elongated tube member and includes a hollow space inside, a stopping portion 61 at an end thereof', and t'our ditches 62 extended longitudinally along an inner periphery thereof: The guide member 6() Is fitted n1 the guide hole 52 of the cover shell 50 around the bar member 44 such that the bar member 44 isextcndcd through the hollow space of the guide member. al he spring 45 has an end contacted against the coupling portion 42 of the handle 40 and the other end contacted against the stopping portion 61 of the guide member 60 such that the Stopping portion 61 of the guide member 6() rests at the stepped portion 54 of the c->vcr shell 50 in normal.
While operating the framing tool of the present invention, a V-shaped nail D is placed into the guide ditches 62 of the guide member 6() and then the user holds the handle 40 to move the framing tool to aim the nail at a corner of a picture frame. In the meantime, the V-shaped nail is positioned longitudinally straight by the guiding of the guide ditches 62 and induced by the magnet 46 so as not to slip away, as shown in FIGS. 3 and 5. After aiming at the corner of the picture frame, punch the framing tool onto the frame. At the same time, the guide member 60 contacts the frame first and then retracts gradually inside the guide hole 52 of the cover shell 50 to squeeze the spring 45 by the stopping portion 61. When the guide member 60 retracts until the nail contacts against the frame, punch the frame tool further towards the *ame such that the nail is pushed by the bar member 44 of the handle 40 to be inserted into the corner of the frame.
Meanwhile, while the user takes the framing tool away from the frame, the guide member 60 returns to its original position by the rebounding resilience of the spring 45.
Because the V-shaped nail is kept positioned longitudinally straight by the guide ditches 62 of the guide member 60 during the whole operation, the nail will not be squashed or projected outwards to hurt the user. Accordingly, the present invention is obviously safe for the user, thereby improving the prior art effectively.
