Abstract

A tool support and lock for supporting and suspending a tool, such as a commercial stapler or similarly constructed tools, from a user's belt. The tool support and lock is an elongated inverted U-shaped loop having an outward diverging leg, rounded upper portion and an opposing leg terminating in an eccentric cam portion, said diverging leg and cam portion having aligned apertures therein, said cam portion sized to frictionally engage the tool and secure the tool components from loosening and disengaging from the tool by means of a fastening device passing through the appertures into the tool.

Description

BACKGROUND OF THE INVENTION

The invention relates to a tool support and lock, and more particularly, to a support which is mounted on a tool and securely locks the structure of the tool together, and clips on to a user's belt which supports and carries the tool dangling therefrom.

Workmen are known to use numerous tool holders for support and carrying various tools on their belts. Generally, these tool supports have been limited only to supporting and carrying the tools and nothing more. Thus, if the structure of the tool has a tendency for its components to loosen and disengage from the tool, the tool holder cannot prevent it from taking place. In many instances, this loosening and disengagement renders the tool inoperable. This situation is particularly true with respect to commercial staplers and other similarly constructed tools. With commercial staplers, a stapler arm encompasses a retention spring mechanism that forces staples up through the arm. As depicted in FIG. 3, a flat mounting base having opposing planar sides and a hook retainer locks into the arm and holds the retention spring under pressure within the arm. The problem is that when using the tool, the hook retainer has a tendency to loosen and disengage from its locked position. This causes the flat mounting base to fall away from the arm making the stapler inoperable.

Accordingly, there is a need for a tool support that clips onto a user's belt which not only will support and carry tools, such as commercial staplers and similarly constructed devices, but will also prevent the tool structure from loosening and falling apart.

SUMMARY OF THE INVENTION

The invention relates to a tool support and lock made from flat spring steel or similar material having an outward diverging leg, a rounded upper portion, and an opposing leg terminating in an eccentric cam shaped portion, said diverging leg and cam shaped portion having aligned apertures disposed therein. It attaches to the user's belt by means of its rounded upper portion clipping onto the belt by having the diverging leg on the inside and the terminal eccentric cam shaped leg on the outside of the belt. It is secured to the tool by sliding the cam portion of the opposing leg in-between the overlapping flat side of the mounting base and the planar side wall of the tool structure, mounting a bolt through the aligned apertures of the opposing legs and the bore in the structure of the tool and tigthening the bolt in place with the interposed cam portion pressing upwardly and outwardly on theoverlapped components with the rounded upper portion in position to clip on to the user's belt.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference is made in detail to the preferred embodiments of the invention as illustrated in FIGS. 1 through 7. [0013]
Shown in FIG. 1 is tool support and lock [0014] 10 for operatively securing a tool, such as a commercial stapler, onto a belt and securing the mechanism of the tool in place. The tool support and lock 10 is made from flat spring steel however plastic or other metal materials can be used. The tool support and lock is bent into an elongated inverted U-shaped loop having an outward diverging leg 12, rounded upper portion 14 and an opposing leg terminating in an eccentric cam portion 16 having an aperture 18 therein. When it is being attached to a workman's belt or other belt, it loops around the belt as shown in FIG. 2 with the diverging leg 12 on the inside of the belt.
The opposing leg with eccentric cam shaped portion has been designed to fit within the [0015] lower structure 20 of a commercial stapler arm 22 as depicted in FIG. 3. Generally, stapler arm 22 encompasses a retention spring mechanism that forces staples up through the arm to the top gun portion of the device which when activated forces staples into an object. As seen in FIG. 3, flat metal mounting base 24 includes opposing flat planar metal sides 26, hook retainer 28 and spring metal sheet 30. Flat metal mounting base 24 fits into the lower structure 20 of stapler arm 22 by means of opposing side walls 26 slidingly and loosely engaging planar flat walls 36 of stapler arm 22 which allows hook 28 to frictionally engage slot 34. Mounting base 24 is further secured to the stapler lower structure 20 by means of bolt 38 threadedly engaged in bore 40 by internally pressing against metal spring 30 adjacent to stapler spring arm 32. However, in use mounting base 24 has a tendency to become loose causing hook 28 to disengage from slot 34 resulting in the entire mounting base to completely fall out of stapler arm lower structure 20 making the stapler inoperable.
In accordance with the present invention in improving the operability of the commercial stapler and similarly constructed tools, there is provided tool support and [0016] lock 10 which is mounted on the stapler as seen in FIGS. 3 and 4. Tool support and lock is fixedly secured to lower stapler structure 20 by removing bolt 38 from bore 40, sliding the cam portion of opposing leg 16 in-between flat side 26 of flat base 24 and planar side wall 36 of stapler structure 20, aligning apertures 18 of the diverging leg and cam portion with bore 40, and fixedly tightening bolt 38 thrrough the apertures into the bore. As seen in FIGS. 4 and 6, the cam portion pressing upwardly against the under surface of base wall 27 locks in place the flat base and hook 28 in slot 34 so that the flat base cannot loosen or fall out with the cam portion in position. Further, the increased tightening pressure on the engaged sides 26 of the base and the planar wall 36 by the interposed cam portion prevents any movement or loosening of the flat base or disengaging of hook 38 from slot 34.
Shown in FIG. 5 is the holder and lock in the unlocked upright position on the tool whereas in FIG. 6 the holder and lock is in the locked upright position. FIG. 7 depicts the commercial stapler hanging from the holder and lock attached to the belt of a workman. [0017]
Although the preferred embodiment has been diverted to a holder and lock for a commercial stapler, tool holder and [0018] lock 10 of the invention is applicable to any tool having sided attachment that becomes loose during use. If there is not a bolt attachment as with the staples a bolt or other attachment would be applicable to hold the holder and lock secured to the tool.
