1. Field of the Invention
The present invention relates generally to wearable tool holders. More particularly, the present invention relates to a tool vest and attachments for webbing-based attachment systems, such as MOLLE interlock attachment systems.
2. Description of the Prior Art
Workers engaged in industrial plant maintenance, construction work, and the like use a variety of hand tools to perform tasks. The work commonly takes place at various heights above the ground and at times is positioned over machinery or other workers. Accordingly, working at height provides many reasons to avoid dropping tools. For instance, a dropped tool wastes time and energy of the worker who must climb down from an elevated location to retrieve the dropped tool before work can continue. Oftentimes, the dropped tool will land in a place out of the user's sight. A search undertaken to locate the tool, even if brief, further wastes valuable work time and interrupts the work flow.
Another more serious concern with dropped hand tools (i.e. hammers, screw drivers, pliers, ratchets, levels, flashlights, tape measures, etc.) is the risk of damage to equipment and death or injury to workers below the drop. Plant equipment can be damaged due to the impact of the falling tool on the machinery or parts. A tool dropped into cooling systems, liquid storage tanks, and other systems may require shutting down machinery or entire operations until the dropped tool can be retrieved.
Even though workers who use hand tools try diligently to maintain a secure grip on the tool, conditions are practically certain to arise in which tools will be dropped. To address tools dropped during use, tool lanyards and tethers have been used to secure the tool to a harness or structure.
U.S. Pat. No. 4,728,123 (1988, Kassal et al.) discloses a releasable strap system. The releasable strap system includes the combination of a hand strap and a device strap. The hand strap is removably connectable around the wrist of a hand and between two of the five fingers of the hand, leaving the hand free for normal use. The hand strap includes two portions, a straight wrist portion and a curved looped portion. The curved loop portion has two ends connected to the straight wrist portion at separated intervals. The straight wrist portion is wrapped around the wrist of the user, threaded through a ring, tightened, and then folded back and locked in position. The device strap is removably connected to the hand strap for supporting an item not held in the user's hand and for quick release from the hand strap.
U.S. Pat. No. 5,130,899 (1992, Larkin et al.) discloses a tool restraint apparatus. The tool restraint includes an elongate elastomeric tether line with respective first and second flexible straps mounted to each end. The first web strap is arranged for selective securement about a user's wrist and includes a first and second end that includes first and second hook-and-loop fastener patches that permit securement of the hook-and-loop fastener patches together. The second web strap is similarly constructed like the first web strap.
Tool drops also occur due to a tool being knocked loose from the worker's tool belt or pocket while climbing or moving about a structure. Workers also use tool pouches designed for certain types of tools, where the tool pouch is removably attached to a tool belt using straps that snap or hook together. Similarly, a tool pouch may be accidentally knocked loose from a tool belt and allowed to fall to the ground.
Carpenter's belts and pockets on vests or pants have been useful for storing tools between uses. Although useful, carpenter's belts and tool pouches sometimes are not configured to securely hold the tool needed for a given job. In such a situation, the worker may need to reconfigure tool pouches on the tool belt, which involves removing some tool pouches and replacing the removed pouches with different tool pouches. Nonetheless, a tool belt has limited space to hold tools and tool pouches.
To address the need to modify one's clothing and equipment for the job at hand, wearable garments with an interlock attaching strap system were developed by the United States Army Natick Soldier Research, Development and Engineering Center. U.S. Pat. No. 5,724,707 to Kirk et al. discloses a system for removably securing smaller objects (e.g., pouches) to a load-bearing platform, such as a vest or backpack. The system, also referred to as Modular Lightweight Load-carrying Equipment or MOLLE, includes a mounting panel on the first object (e.g., garment), where the mounting panel includes strips of webbing evenly spaced and stitched across the mounting surface, also known as PALS webbing (pouch attachment ladder system). The PALS grid consists of horizontal rows of 1-inch Mil-W-43668 Type III nylon webbings that are spaced one inch apart and secured to the backing at 1.5 inch intervals. The spacing between the webbing rows allows webbings on a second object (e.g., a pouch) to fit therebetween. The webbings are secured with stitching perpendicular to the webbing to create channels between the webbing and the garment through which a strap may be inserted.
In an example of using the MOLLE system, a pouch has at least one attached flexible strap that extends vertically along the back of the pouch. One end of the flexible strap is secured near the pouch opening and the other end of the strap has a snap button that engages a snap post near the base of the pouch. Webbings on the garment receive the webbings on the pouch in an interlocking fashion. The strap of the pouch is passed through the webbings on the garment and then again through the webbings on the pouch in an interlocking fashion in order to effectively and removably mount the pouch to the garment. The fastener part at the lower end of the strap is then attached to a corresponding fastener part on the back surface of the pouch. Backpacks, vests, and other wearable garments employ the interlock attaching system to enable the user to position necessary pouches or other objects where they are most useful to the individual user.
A variation on the MOLLE system is a quick-mount interlocking attaching system disclosed in U.S. Pat. No. 7,080,430 to Wemmer. The Wemmer system includes a one-piece molded substrate adapter, a one-piece molded accessory adapter, and a discrete locking member. The substrate adapter has a flat base that is affixed to the object (e.g., vest). Raised regions are formed on the base at spaced-apart locations and aligned along an axis and include slots to define openings. The accessory adapter is similarly constructed with a flat base having raised regions in a spaced-apart relation along a second axis, where the raised regions also have slots that define openings. The raised regions on the accessory adapter are spaced to occupy voids between the raised regions on the substrate adapter. The locking member has a leading end and a trailing end and is removably insertable leading-end-first through the passages on the raised regions of both adapters to interlock the accessory adapter to the substrate adapter.
While MOLLE interlock attachment systems and PALS webbing have been implemented on vests, backpacks, tactical clothing, and mountaineering equipment, the interlock attachment systems have not adequately addressed the needs of workers who use hand tools on a jobsite. Particularly, MOLLE-compatible pouches and pockets used for tactical applications typically use a snap button fastener at the end of the strap, where the corresponding snap on the pouch is located on the rear face of the pouch. If the pouch catches on another object and is pulled away from the garment, the snap-button fastener can be inadvertently disconnected and allow the pouch to become detached from the garment. Similarly, accidental release of the locking member of the Wemmer system allows the accessory pocket to quickly become decoupled from the garment. Additionally, a fastener located between a pouch and the garment creates a region that can be uncomfortable and sometimes painful when impacted against one's body
Additionally, tactical MOLLE-compatible vests and other garments have webbing or interlock members aligned in horizontal rows across the garment. While magazine pouches, flashlight holders, and other pouches are useful when oriented vertically (since fastened perpendicular to the webbing), workers on a ladder or other precarious position often need to be able to access and operate a tool with only one hand. Doing so is easier when the tool pouch is angled in a “cross-draw” orientation with respect to a vertical axis, where the pouch opening is oriented upward and inward towards the garment center line, such as when angled upward towards the centrally-located front opening of a vest. Thus, the worker may reach across the body (e.g., with the right hand) to retrieve a tool from a pocket located on the opposite-side (e.g., on the user's left, front or left side) of the garment and angled conveniently for easy access.
Due to the deficiencies of prior art tool vests and MOLLE systems, a need exists for an improved modular garment system for hand tools. Embodiments of the present invention address the deficiencies of the prior art by providing a system employing a modular garment and accessory attachments therefor.
In one aspect of the present invention, a modular tool storage garment includes a wearable upper-body garment with a garment front panel and a garment rear panel. For example, the garment is a vest. The garment has a plurality of first webbings secured to the garment front panel in a substantially parallel relation, where each of the first webbings defines at least one passageway between the webbing and the front panel and passing perpendicular to the webbing. The first webbings extend superiorly and laterally away from a sternal region dividing the garment front panel into a right half and a left half.
In another embodiment, the garment includes a plurality of second webbings secured to the garment front portion in a substantially parallel relation. Each of the plurality of second webbings defines a plurality of second passageways between the webbing and the garment, where the passageways extend generally perpendicular to the webbing. Each of the plurality of second webbings is substantially horizontal as viewed with the garment donned by a user in a standing, upright position.
In some embodiments, the garment includes at least one tool holder or accessory pouch configured to attach to the webbings of the garment.
In another embodiment, the system includes a safety harness attached to the garment and including a left shoulder strap, a right shoulder strap, a left leg loop, and a right leg loop. In another embodiment, the safety harness includes a harness loop secured to the garment rear surface and to the harness.
In another embodiment, the garment includes one or more garment tether pockets secured to an inside surface of the front panel, where each of the one or more garment tether pockets is sized and configured to house a retractor body with a retractable tether cord. For each garment tether pocket, the front panel defines at least one garment tether opening sized for passage of the retractable tether cord.
In another aspect of the present invention, a tool pouch compatible with MOLLE/PALS webbing includes a holder body defining a tool compartment with a holder opening, a holder back surface extending along a longitudinal pouch axis, and a holder bottom surface. The tool holder has at least one strap with a strap proximal end portion, a strap body portion, and a strap distal end portion, where the strap proximal end portion is secured to the holder back surface adjacent the holder opening and the strap body portion extends along the holder back surface to the strap distal end portion. A connector first portion is secured to the strap distal end portion of each strap. A connector second portion is secured to a bottom end portion of the tool holder and configured to mate with and engage the connector first portion to secure the strap distal end portion to the tool holder.
In another embodiment, a tool holder compatible with MOLLE/PALS webbing systems has a holder body defining a tool compartment with a holder opening, a back surface extending along a holder longitudinal axis, a bottom surface, and a front surface. A strap has a first end secured adjacent a top end of the tool holder with the strap body extending down along the holder back surface and around the bottom surface to the strap distal end portion, which includes a connector first portion. A connector second portion is secured to a holder front surface for releasably engaging the connector first portion. When the connector first portion engages the connector second portion, the strap wraps around the holder bottom surface and extends part way upward along the holder front surface.
In another embodiment, the tool holder defines a retractor pocket located between the back surface and the tool compartment, where the retractor pocket defines a tether opening adjacent the holder opening. In one embodiment, the tether opening is an opening in a seam of the retractor pocket.
In another embodiment, the proximal end portions of the strap(s) are secured into the seam of the retractor pocket, such as by stitching.
In one embodiment, a strap extends at an angle along the holder back surface with respect to the central pouch axis. For example, the strap extends diagonally across the back surface.
In another embodiment, the connector first portion of a strap has at least two corresponding connector second portions. For example, a single strap with a single connector first portion may be connected to one of a plurality of connector second portions, thereby allowing the user to choose between the strap extending longitudinally and the strap extending at an angle across the back surface of the tool holder with respect to the longitudinal pouch axis. This option allows the user to use the tool holder with a variety of MOLLE/PALS systems and achieve a tool holder angled with respect to a vertical axis.
In another embodiment, the connector second portion is secured to the holder bottom surface. In one embodiment, the connector second portion is secured through the holder bottom surface. In some embodiments, the holder bottom surface and the back surface define an acute internal angle.
In another embodiment, the holder body is made of a pliable material and the holder includes a self-tightening strap secured to and extending between a first side portion and a second side portion of the holder body and extending across a middle portion of the holder body. The self-tightening strap comprises an elastic material and is sized to bias the tool compartment towards a closed state along the middle portion. Elastic properties of the self-tightening strap urge the middle portion against an implement installed in the tool compartment to frictionally engage the implement, thereby preventing the implement from accidental removal from the tool compartment.
The preferred embodiment(s) of the present invention is illustrated in
In one embodiment, garment 100 has an opening 106 to permit the user to don and take off garment 100. In other embodiments, garment 100 is configured as a pull-over shirt or vest that has adjustable straps to tighten garment 100 on the user after donning. Opening 106 may be on front panel 102 (e.g., along sternal region 103), on back panel 104, along one or both side seams 110a, 110b between front panel 102 and back panel 104, or at other locations on garment 100. In one embodiment, opening 106 is selectively openable and closable by the user with a closure 108. Closure 108 may be a zipper, straps with clips, hooks, straps, ties, buttons, or any other closure deemed appropriate and sufficiently secure for the intended use. Optionally, garment 100 includes sleeves (not shown).
A plurality of first webbings 130 are secured to an outside surface 102a of front panel 102 and extend upward and outward from sternal region 103 and/or central longitudinal garment axis 114 as viewed in
First webbings 130 are secured to front panel 102 with fasteners 132 at evenly-spaced locations. Fasteners 132 may be, for example, stitching, rivets, snaps, or other fastener 132. Consistent with known MOLLE/PALS webbing panels, spaced-apart fasteners 132 on each first webbing 130 define passageways 134 between webbing 130 and front panel 102, where each passageway 134 is aligned along a passageway axis 135 generally perpendicular to first webbings 130. For example, first webbings 130 are made of heavy-duty nylon with a webbing width W1 of about one inch (2.54 cm) and are secured to front panel 102 by stitching that extends perpendicularly across webbing width W1 and spaced about every 1.5 inches (3.81 cm) along the webbing. First webbings 130 may be made of other materials, including woven and non-woven fabrics, stretchable fabrics, and other webbings. Other values for width W1 and fastener spacing are acceptable. Consistent with MOLLE/PALS systems of the prior art, fasteners 133 and passageways 134 of adjacent webbings 130 are generally aligned along axis 135 extending perpendicular to webbings 130.
In one embodiment, some or all of first webbings 130 are inclined at an angle α of about 45° with respect to a horizontal axis 113. Other values of angle α are also acceptable, such as 20°, 30°, and 37.5°. In some embodiments, first right webbings 130a are inclined with respect to horizontal axis 113 and have a value of α that is different from that of first left webbings 130b. For example, first right webbings 130a are inclined at 45° and first left webbings are inclined at 30°. In other embodiments, first right webbings 130a or first left webbings 130b are parallel to horizontal axis 113.

Optionally, garment 100 includes a plurality of horizontal sternal webbings 150 on sternal region 103. Sternal webbings 150 extend parallel to horizontal axis 113 and have a significantly reduced length compared to waist 112. For example, each sternal webbing 150 defines one to three sternal passageways 152 similar to passageways 134 as discussed above for first webbings 130. Sternal webbings 150 are disposed in a parallel relation, typically with a sternal passageway 152 of each sternal webbing 150 centered along sternal region 103 and along longitudinal garment axis 114. In one embodiment, sternal webbings 150 are spaced from each other by sternal webbing width W3. In other embodiments, some or all of sternal webbings 150 are positioned to abut or nearly abut each other. In one embodiment, sternal webbings width W3 is the same as webbing width W1 for first webbings 130. In other embodiments, sternal webbing width W3 is less than or greater than webbing width W1, such as for specialty pouches for small items.

In use, first webbings 130, second webbings 140, and sternal webbings 150 may be used to configure garment 100 for attachment of accessories and pouches in optimal locations and orientations for workers who use hand tools. When garment 100 includes one or more regions with horizontal webbings, inclined webbings, inclined webbings at various angles α, and sternal webbings, and when tool holders 200 include straps 230 configured for use with such webbings, a worker has many, many options available for a tool vest or other garment 100 with a customizable arrangement of removable accessories, such as tool holders 200. Of course, garment 100 can be used with other known accessory pouches, and attachments compatible with MOLLE/PALS webbing. When attaching a pouch or accessory to garment 100 using first webbings 130, the pouch or accessory is inclined with its opening in a “cross-draw” orientation and facing upwards an inwards at an angle defined by the webbings. The user then has improved access to the inclined pouch, which improves efficiency and reduces the frequency of dropped tools. When integrally combined with a harness 304, garment 100 becomes a safe and effective way to hold tools in addition to addressing fall prevention.
Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
