Description
- This application is a continuation application of U.S. Application Ser. No. 11/122,286 filed May 4, 2005, which claims priority to U.S. Provisional Application Ser. No. 60/567,956 filed May 4, 2004, the entire disclosures of which are incorporated herein by reference.
- The present invention relates to a case for holding tools, and, more specifically, to a case adapted for use with a ladder.
- A desirable tool case serves several functions, for example, providing a location for tools to be stored and easily located when they are needed. Tools are often needed when a user is performing tasks in elevated positions on a ladder. As such, certain devices have been developed for supporting tools and/or other articles upon a ladder. However, these devices often fail to serve the functions expected from desirable tool cases. Also, such known devices often do not allow tools to be easily organized and readily accessed and/or have very limited storage capacity.
- Additionally, such known devices are often unstable when placed upon a ladder and/or are difficult to use in locations away from a ladder. For example, U.S. Pat. No. 4,356,854 describes a pouch having a flexible skirt, which may hang around the top of a step ladder. When the flexible pouch is positioned on the ladder, the weight of articles in its pockets, particularly the side pockets that hang with the flexible skirt around the top of the ladder, stabilize the pouch on the ladder. As such, the stability of the pouch on the ladder is dependent upon having tools of a particular weight positioned in particular pockets of the pouch; such stability could be jeopardized if a weighty tool were removed from the pocket and used. Additionally, the flexible pouch collapses when positioned on other surfaces, such as a table-top or a floor, making it difficult to use in locations away from the ladder.
- Furthermore, certain known devices are often of a design that is cumbersome to manufacture, to store and to use. For example, U.S. Pat. No. 5,901,998 describes a tool carrier that is made from a strong lightweight material, such as plastic, having a recess formed in a bottom surface and various cavities molded through an upper surface, shaped to hold particular tools. In this regard, the tool carrier has a molded, rigid construction that can be cumbersome to manufacture, store and maneuver. Additionally, the tool carrier's molded cavities are designed to hold particular tools; once formed, these cavities are not appropriate for holding other tools that may be useful or desirable in certain situations.
- As such, there is a need in the art for a device that satisfactorily addresses the above-mentioned problems associated with known devices designed for supporting tools and/or other articles upon a ladder.
- The present invention addresses the above-identified problems, and others, by providing a tool case, which is adapted to engage a ladder, provides ample storage capacity, allows for tools to be easily organized and readily accessed, has a beneficial multi-piece construction, and allows for efficient use upon a ladder, as well as in locations away from a ladder.
- The tool case of the present invention is constructed from a substantially rigid skeleton made, for example, from a molded polymer or a metal. Furthermore, the tool case may include flexible elements. For example, an embodiment of the tool case has a rigid skeleton that is covered with durable fabric material. The tool case may also or alternatively include a casing associated with the skeleton, which is made from a flexible material, such as a polymer or metal sheet that provides a stable surface, but may be flexed. An embodiment of the tool case includes a casing that is positioned substantially adjacent to and is joined to the skeleton.
- Generally, the skeleton has a substantially horizontal bottom surface and at least one substantially vertical surface extending from the horizontal bottom surface, which together 15 define a cavity for receiving a top portion of a ladder. A single continuous vertical surface extending from the horizontal bottom surface may be provided, or multiple vertical surfaces may be provided, as long as the one or more vertical surfaces and the horizontal bottom surface define a cavity capable of receiving a top portion of a ladder.
- Additionally, the skeleton has a substantially horizontal top surface and at least one substantially vertical surface extending from the horizontal top surface, which together define a compartment for holding tools. A single continuous vertical surface extending from the horizontal top surface may be provided, or multiple vertical surfaces may be provided, as long as the one or more vertical surfaces and the top surface define a compartment capable of holding tools. In any event, the accessible surfaces of the skeleton are provided with various means for holding and organizing tools and accessories, for example, pockets, straps or brackets.
- In an embodiment of the tool case, the substantially horizontal top surface and the substantially horizontal bottom surface are provided on a single component, a base having a top surface and a bottom surface. Additionally, in the embodiment of the tool case, the vertical surfaces extending from the horizontal top surface and the vertical surfaces extending from the horizontal bottom surface are provided by four side walls having upper portions extending upwardly from the base, and lower portions extending downwardly from the base. Thus, the base, together with the upper portions of the side walls define a compartment for holding tools, while the base, together with the lower portions of the side walls define a cavity capable of receiving a top portion of a ladder.

For example, as shown in
FIG. 1 , an illustrated embodiment of thetool case 10 may be positioned on the top of astep ladder 100. - The tool case of the present invention is constructed from a substantially rigid skeleton made, for example, from a molded polymer or a metal. Furthermore, the tool case may include flexible elements. For example, in the illustrated embodiment, the
tool case 10 has a rigid skeleton that is covered with durable fabric material, such as a heavy nylon; however, it may be constructed from a variety of materials including PP webbing, various natural or synthetic cloths or leather. The tool case may also or alternatively include a casing associated with the skeleton, which is made from a flexible material, such as a polymer or metal sheet that provides a stable surface, but may be flexed. In the illustrated embodiment, thetool case 10 includes a casing that is positioned substantially adjacent to and is joined to the skeleton, as will be described below. - Generally, the skeleton has a substantially horizontal bottom surface and at least one substantially vertical surface extending from the horizontal bottom surface, which together define a cavity for receiving a top portion of a ladder. A single continuous vertical surface extending from the horizontal bottom surface may be provided, or multiple vertical surfaces may be provided, as long as the one or more vertical surfaces and the horizontal bottom surface define a cavity capable of receiving a top portion of a ladder.
- Additionally, the skeleton has a substantially horizontal top surface and at least one substantially vertical surface extending from the horizontal top surface, which together define a compartment for holding tools. A single continuous vertical surface extending from the horizontal top surface may be provided, or multiple vertical surfaces may be provided, as long as the one or more vertical surfaces and the top surface define a compartment capable of holding tools. In any event, the accessible surfaces of the skeleton are provided with various means for holding and organizing tools and accessories, for example, pockets, straps or brackets.
- In the illustrated embodiment of the
tool case 10, as described with reference toFIGS. 2-4 , the substantially horizontal top surface and the substantially horizontal bottom surface are provided on a single component, abase 12 having atop surface 12 a and abottom surface 12 b. Additionally, in the illustrated embodiment, the vertical surfaces extending from the horizontal top surface and the vertical surfaces extending from the horizontal bottom surface are provided by fourside walls upper portions base 12, andlower portions base 12. Thus, thebase 12, together with theupper portions side walls compartment 22 for holding tools, while thebase 12, together with thelower portions side walls cavity 24 capable of receiving a top portion of a ladder. Although thecompartment 22 of the illustrated embodiment is not subdivided, it is contemplated that it could be divided into multiple sub-compartments. - In addition to the
compartment 22, thetool case 10 may include a variety of holding mechanisms for securing and organizing tools and accessories. For example, with reference toFIG. 5 , secured to an outside surface of afirst sidewall 14 of thetool case 10 is a pair ofopen pockets FIGS. 2 and 6 , secured to an outside surface of asecond sidewall 16 of the embodiment is a pair ofpouches pouches pouches - Still referring to
FIGS. 2 and 6 , also secured to thesecond sidewall 16 of thetool case 10 is a strap andclasp combination 30, which may be clipped onto various items for securing the items to thetool case 10. Abracket 32 is also provided on thesecond sidewall 16 for securing additional items to thetool case 10. - Referring now to
FIGS. 2 and 7 , secured to an outside surface of athird sidewall 18 of thetool case 10 are another pair ofopen pockets - With reference to
FIGS. 7 and 8 , apocket 34 is provided on an outside surface of afourth wall 20, whichpocket 34 may be selectively closed using aclip 35. - With reference to FIGS. 2 and 5-8, a pair of
straps second wall 16 and thefourth wall 20 for securing items to thetool case 10 using hook-and-loop fastening material. - Finally, with reference to
FIG. 9 , a zip-closure compartment 36 is provided on an inside surface of thesecond wall 16. - Of course, the foregoing are merely examples of some of the holding mechanisms that may be used for securing and organizing tools and accessories of various shapes and sizes and any such mechanisms may be incorporated into the tool case without departing from the spirit and scope of the present invention.
- As mentioned above, it is contemplated that the tool case could also include a casing made from a flexible material, such as a polymer or metal sheet that provides a stable surface, but may be flexed. The casing may be positioned substantially adjacent to the horizontal bottom surface and the vertical surface defining the cavity. As such, a space may be defined between the horizontal bottom surface and the vertical surface defining the cavity.
- The illustrated embodiment of the
tool case 10 includes such a casing, best shown inFIGS. 3 and 4 , which includes: asaddle 46 defining achannel 48; and a pair of generally “L”-shapedflaps - The casing allows for the
tool case 10 to be snuggly and stably mated with the upper portion of aladder 100. Thesaddle 46 is positioned within thecavity 24 and thechannel 48 is shaped to snuggly receive the top portion of a ladder. Afirst edge 56 of thesaddle 46 is joined to alower end 58 of oneflap 50 and asecond edge 60 of thesaddle 46 is joined to alower end 62 of theother flap 52. Upper ends 64, 66 of eachflap side walls space 68 remains between theskeleton casing saddle 46 and thebottom surface 12 b of thebase 12, a space remains between thesaddle 46 and thelower portions sidewalls side walls flaps space 68, along with the flexible nature of the casing material, provides certain benefits. - For example, the
space 68 and flexible nature of the casing material allows thetool case 10 to be snuggly positioned on top of ladders having upper portions that differ. For another example, because thesaddle 46 has the ability to move within thecavity 24, it can be readily guided around the top portion of a ladder. That is to say, thetool case 10 can brought into contact with theladder 100 such that it forms an angle with theplatform 140 before being rotated over the top portion of theladder 100 to a substantially horizontal orientation. - For yet another example, the
space 68 and flexible nature of the casing material allows thetool case 10 to move slightly while positioned on theladder 100, which movement provides a certain stability. That is to say, when a tool is accessed from thetool case 10, a force is exerted upon thetool case 10, which force is absorbed by thespace 68 and flexible nature of the casing material, such that the force is not transferred to the ladder, which transfer could cause the ladder to become unstable. - In any event, regardless of the particular components making up the skeleton and casing (in embodiments where a casing is provided), as mentioned above, it is contemplated that the tool case could be covered with fabric. In the illustrated embodiment, the skeleton and casing of the
tool case 10 are covered with fabric, with the holding mechanisms, including, for example, theopen pockets saddle 46 and theflaps - In the illustrated embodiment, the
tool case 10 additionally includes ahandle 40 that may be secured to thecase 10 to allow thecase 10 to be more easily carried. Thehandle 40 is secured to the inside surface of thesecond wall 16 and an inside surface of thethird wall 20 and has a rigid construction with a paddedgrip 70 for supplying a comfortable and slip-resistant area on thehandle 40 for grasping thetool case 10. - The illustrated embodiment of the
tool case 10 additionally includes a pair offlanges side walls flanges straps flanges side walls tool case 10 was forced against a wall, theflanges side walls flanges flanges flanges - The illustrated embodiment of the
tool case 10 may be used in the following manner. With reference toFIG. 1 , anexemplary ladder 100 that may be used with thetool case 10 includes a pair ofrails 110 with a plurality of substantiallyhorizontal steps 120 extending therebetween. The tops of therails 110 terminate at aplatform 140. Theplatform 140 has a pair of downwardly extendinglegs 130 pivotally attached thereto, which, along with therails 120, support theladder 100 while it is being used. - The
tool case 10 is designed to engage theladder 100 by lowering thetool case 10 onto theladder 100 such that the top portion of the ladder is contained within thechannel 48 defined by thesaddle 46 of the casing. In other embodiments that do not include a casing, the tool case may be lowered onto theladder 100 such that top portion of the ladder is contained within the cavity defined by the horizontal bottom surface and at least one vertical surface extending therefrom, such that the horizontal bottom surface rests on theplatform 140 of theladder 100. For example, with reference to the skeleton of the illustrated embodiment, thetool case 10 may be lowered onto theladder 100 such that the top portion of theladder 100 is contained within thecavity 24 defined by thebottom surface 12 b of thebase 12 and thelower portions side walls bottom surface 12 b rests on theplatform 140 of theladder 100. When thetool case 10 is so positioned, the portion of thewalls base 12 of thecase 10 surround theplatform 140, a top 5 portion of therails 110 and a top portion of thelegs 130. That is to say, thecavity 24 receives and retains a top portion of theladder 100, allowing thetool case 10 to engage theladder 100. - Although the terms horizontal and vertical sometime appear unmodified in this document; these terms are at all times to be understood as being modified by the term “substantially,” unless otherwise indicated.
- One of ordinary skill in the art will also recognize that additional embodiments are possible without departing from the teachings of the present invention or the scope of the claims which follow. This detailed description, and particularly the specific details of the exemplary embodiment disclosed therein, is given primarily for clarity of understanding, and no unnecessary limitations are to be understood therefrom, for modifications will become obvious to those skilled in the art upon reading this disclosure and may be made without departing from the spirit or scope of the claimed invention.
