TOOL HOLSTER FOR ATTACHMENT TO LEG
A tool holster includes a connector of a clip is provided for detachably securing a tool to a leg harness. A fastener stud is attachable to the tool. The holder rotatably receives the fastener stud for movements between a first angular orientation that permits the fastener stud to be selectively received and removed from the holder and a second angular orientation that prevents the fastener stud received within the holder from being separated or removed from the holder. A support member is attached to the fastener stud for sharing common rotational movements therewith and connectable to a tool to be supported. The support member is oriented to move the fastener stud to the second angular orientation only when the tool is freely suspended on the holder under the action of gravity regardless of the position or orientation of the user's leg.
1. Field of the Invention
This invention generally relates to devices for supporting tools on the body of a user and, more specifically, to a tool holster for attachment to a thigh of a user.
2. Description of the Prior Art
While power and air tools continue to be made more efficient and lighter in weight, they continue to be generally heavy and bulky. Contractors frequently have a need to transport such tools to locations where work is in progress. This may require carrying a tool with one or both hands. However, this is not always practical since the user's hand(s) may need to perform other functions such as holding the rungs of a ladder while the user is climbing up or down the ladder.
As battery powered tools continue to proliferate and the variety such tools increases, contractors increasingly rely on such tools and, at times, actually need to employ more than one such tool at a work site. Numerous devices have been proposed for attaching such tools to the body or apparel of a user to free up the user's hands for other purposes, including enhancing the safe navigation to the work site with the tools and possibly other materials that the worker needs to use at the work site.
As noted, such tools are generally heavy, particularly battery operated tools, since the batteries themselves are quite heavy. Therefore, not only must the safety of the user be factored in but so must be the comfort and convenience of carrying such heavy tools about without compromising the safety or effectiveness of the user. For this purpose, many tool belts and tool belt accessories have been proposed that are suitable for attachment to a belt of the user designed to support the tools. However, in a typical situation, the tool belt is already populated by other tools, such as hammers, crow bars, etc. and pouches for fasteners such as nails, small hand tools and the like. Power tools, because of their generally large size, occupy much real estate that could otherwise be sued for smaller tools, pouches, etc.
Many tool holders have been proposed that are secured to the belt or a tool belt. However, prior tool holding devices fail to provide the degree of safety to the user as well as others at a work site. This could create hazardous conditions at the work site when, for example, a user climbs up a ladder with numerous devices and tools that are secured to his person.
Tool holders must, therefore, not only be safe and comfortable to the user but also be convenient to use. The tools must be safely supported on the tool holder when there is no need for its use while allowing the user to quickly and conveniently remove the tool and use it as needed without compromising safety to the user and/or others at the work site. The tool must, therefore, be capable of being quickly and easily removed from the tool holder as needed, especially when the user is in compromising situations, such as on a ladder, on a roof, etc. After the tool has been used it must be capable of being quickly and conveniently re-connected to the tool holster in a safe and reliable manner so that the user needs not to be concerned about the tool accidently separating and possibly causing injury or damage at the site.
The prior art references indicate that quick disconnect connectors of the type contemplated are well known in the art. Tool belts with numerous types of quick disconnect devices for quick connect and disconnect of a tool are also known. The prior art does not, however, show a tool holster of the type suggested that is attached directly to the leg or the thigh of the user and not directly to the belt of the user. The prior art, accordingly, also fails to teach the use of an ancillary belt between a leg holster and the waist belt for securing the same in place.
U.S. Pat. No. 1,043,675 discloses a folding leg bracket which is designed to be secured to a carpenters leg above the knee so that a board can be supported on the bracket while cutting the board. The device disclosed, therefore, is not to safely support tools, but is simply a pivotably mounted support arm attached to a leg harness that positions at a location convenient for supporting a board, such as sheet rock, if a carpenter cannot otherwise avail himself on a support surface on which to support the board to be cut.
Quick disconnect fastening devices that provide secure connection or disconnection when desired are also known and shown, for example, in U.S. Pat. Nos. 4,419,794 to Horton, Jr. et al.; 6,655,560 to Kahn; and 6,641,011 to Kahn. Tool hanging devices are also disclosed in U.S. Pat. No. 5,799,847 to Sandor. Sandor's device requires that the tool be rotated 90° from the hanging position to allow the tool to be removed. The remaining references show other such structures. However, all of these devices are shown to be attached or attachable to a typical belt or tool belt worn about the waist of a user. None teach or suggest a tool holster to be tightened or secured to the leg or around the thigh of the user. Accordingly, as indicated, none of these references teach the use of an ancillary strap or belt to connect the belt worn around the waist to maintain the tool holster in its desired position without danger of its slipping down the leg as a result of the heavy nature of the tools supported.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the invention to provide a tool holster for attaching tools or the like to the leg of a user without interfering with the user's movements or motions at a work site.
It is another object of the invention to provide a tool holder that is simple in construction and economical to manufacture.
It is still another object of the invention to provide a tool holster of a type of the discussion that enhances safety at a work site to prevent injury or damage from inadvertent separation of a tool from a holster.
It is yet another object of the invention to provide a tool holster as in the previous objects that is convenient to use and enables a user to quickly and conveniently separate a tool on the holster for use or re-attachment a tool to the holster when use of the tool is no longer needed.
It is a further object of the invention to provide a tool holster as in the previous objects that allows the user to secure a bulky and heavy tool to the person without interfering with the use of a tool belt that may also be used to support or carry other materials or other tools that user may require at a work site.
In order to achieve the above objects as well as others that will become evident hereinafter, a tool holster for attachment to a leg of a user comprises a leg harness for attachment to the thigh of a user. A connector is provided for detachably securing a tool to the harness. The connector comprises a holder permanently attached to the harness. A fastener stud including means for attachment to the tool. The holder is configured to rotatebly receive the fastener stud for movements between a first angular orientation that permits the fastener stud to be selectively received and removed from the holder and the second angular orientation that prevents the fastener stud received within the holder from being separated or removed from the holder. A support member is attached to the fastener stud for common rotational movements therewith and provided with means for connection to a tool to be supported. The support member is oriented to move the fastener stud to the second angular orientation only when the tool is freely suspended on the holder under the action of gravity. In this manner, the tool is normally reliably secured to the tool holster independently of a relative position of a user's leg to which the harness is attached and can only be separated from the harness when the user rotates the tool and thereby also said fastener stud to set first angular orientation.
Those skilled in the art will appreciate the improvements and advantages that derive from the present invention upon reading the following detailed description, claims, and drawings, in which:
