The present invention is directed toward a securing device that is attached to a ladder, and more specifically, a securing device that extends from a ladder to secure the ladder to a support structure to prevent slippage of the ladder during use.
Use of ladders in the field can present certain dangers where the ladder is not properly secured to a particular structure or on a particular terrain. Where a ladder is placed on a slope, the ladder can slip away from a support structure while the person is on the ladder. This is particularly true of tall ladders and extension ladders. Other dangers can include a ladder falling away from the support structure, where a ladder may be positioned in close proximity to the support structure.
According to an aspect of the present disclosure, a ladder securing device includes a housing that has a rotating interface configured to attach to a portion of a ladder. The housing is rotationally operable between an attaching position and a bypass position. A reel is disposed within the housing, and includes a strap that is selectively extendable to a plurality of extended positions. The reel biases the strap to a coiled position around a spool of the reel and within the housing. A retainer is attached to an end of the strap, and is configured to attach to one of the ladder and the housing in a securing position that secures the ladder to an adjacent support structure.
According to another aspect of the present disclosure, a ladder includes a base section. A fly section slidably operates relative to the base section to define a desired height of an engaging end of the fly section. A housing has a rotating interface configured to attach to a portion of the base section. The housing is rotationally operable between an attaching position and a bypass position. The housing in the bypass position is positioned within a storage space defined between adjacent rungs and opposing side rails of the base section. A reel is disposed within the housing, and includes a strap that is selectively extendable to a plurality of extended positions. The reel biases the strap to a coiled position around a spool of the reel and within the housing. A retainer is attached to an end of the strap, and is configured to attach to one of the base section and the housing in a securing position that secures the ladder to an adjacent support structure. The securing position is further defined by the strap being rotationally secured in a desired extended position of the plurality of extended positions.
According to yet another aspect of the present disclosure, a method for securing an extension ladder to an adjacent support structure includes the steps of operating a fly section of the extension ladder relative to a base section of the extension ladder to define a desired length, positioning the ladder against a support structure, rotating a housing for a ladder securing device from a bypass position to an attaching position, extending a strap from a coiled position within the housing to a desired extended position to be encircled around the structure, attaching a retaining of the strap in the desired extended position to the base section, retracting the strap to eliminate slack in the strap encircling the support structure, activating a reel lock that secures a rotational position of the reel of the housing and secures the strap in the desired extended position, disengaging the reel lock to allow the reel to bias the strap back to a coiled position within the housing, and rotating the housing from the attaching position to the bypass position.
These and other aspects, objects, and features of the present invention will be understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

As required, detailed embodiments of the present disclosure are disclosed herein;
however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to a detailed design; some schematics may be exaggerated or minimized to show function overview. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the concepts as oriented in
The present illustrated embodiments reside primarily in combinations of method steps and apparatus components related to a ladder securing apparatus that maintains the position of a ladder with respect to a support substrate. Accordingly, the apparatus components and method steps have been represented, where appropriate, by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. Further, like numerals in the description and drawings represent like elements.
As used herein, the term “and/or,” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items, can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
In this document, relational terms, such as first and second, top and bottom, and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
As used herein, the term “about” means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. When the term “about” is used in describing a value or an end-point of a range, the disclosure should be understood to include the specific value or end-point referred to. Whether or not a numerical value or end-point of a range in the specification recites “about,” the numerical value or end-point of a range is intended to include two embodiments: one modified by “about,” and one not modified by “about.” It will be further understood that the end-points of each of the ranges are significant both in relation to the other end-point, and independently of the other end-point.
The terms “substantial,” “substantially,” and variations thereof as used herein are intended to note that a described feature is equal or approximately equal to a value or description. For example, a “substantially planar” surface is intended to denote a surface that is planar or approximately planar. Moreover, “substantially” is intended to denote that two values are equal or approximately equal. In some embodiments, “substantially” may denote values within about 10% of each other, such as within about 5% of each other, or within about 2% of each other.
As used herein the terms “the,” “a,” or “an,” mean “at least one,” and should not be limited to “only one” unless explicitly indicated to the contrary. Thus, for example, reference to “a component” includes embodiments having two or more such components unless the context clearly indicates otherwise.

The base section 64 of the extension ladder 12 can include various feet 70 or anti-slip features that can be used to secure the ladder 12 to a substrate, such as the ground 60. While these anti-slip features are useful on stable substrates, such as concrete, structural floors, and other level surfaces, these feet 70 may have difficulty in securing the ladder 12 within open terrain, gravel and other non-paved surfaced or other non-finished surfaces. Accordingly, the securing device 10 is attached to the ladder 12, typically within the base section 64, for securing the ladder 12 to the adjacent support structure 14 to address possible slippage of the ladder 12 away from the adjacent support structure 14 or falling of the ladder 12 away from the adjacent support structure 14.
The securing device 10 is attached to a side rail 38 of the base section 64 for a ladder 12 using a bracket 90 that can be attached via the fasteners, welding, or other similar securing mechanism or method and can fixedly secure the bracket 90 to the side rail 38. The housing 16 is attached to the bracket 90 via the rotating interface 18, such as a hinge, that allows the housing 16 to move between the attaching position 20 and the bypass position 22. The rotating interface 18 can also include an articulating mechanism that selectively biases the housing 16 at least toward the bypass position 22 and, in certain aspects of the device, the attaching position 20. This articulating mechanism can also be used to selectively and temporarily secure the housing 16 in the attaching position 20 and the bypass position 22. The housing 16 in the bypass position 22 is typically oriented and positioned within a storage space 92 that is defined between adjacent rungs 40 of the base section 64 and opposing side rails 38 of the base section 64 for the extension ladder 12. When in use, the securing device 10 for the ladder 12 can be rotated from the bypass position 22 to the attaching position 20. In this manner, the housing 16 is rotated to extend outward from the storage space 92 that is defined between the adjacent rungs 40 and side rails 38 for the base section 64 of the ladder 12. In addition, the attaching position 20 orients the housing 16 to extend from the storage space 92. In certain aspects of the device, such as particularly long extension ladders 12, each of the base section 64 and the fly section 62 can include a dedicated securing device 10. These securing devices 10 can be used to provide multiple layers of support for securing the ladder 12 to the support structure 14.
As exemplified in
As exemplified, in
Where the ladder 12 is placed on a slope, certain slippage may occur when the securing device 10 is engaged with the support structure 14 in a securing position 112. This slippage, due to the presence of the securing device 10, can be limited to a small range of slippage. As the ladder 12 slides away from the support structure 14, the retainer 34, the strap 26 and the housing 16 of the securing device 10 limits the outward movement 114 of the base section 64 away from the support structure 14. Accordingly, the base section 64 of the ladder 12 can only move a small distance from the support structure 14. At this point, the strap 26 is made even more taught and the ladder 12 is made secure to prevent further slippage or other outward movement 114 away from the support structure 14.

A reel lock or other locking mechanism 80 can be used to secure the reel 24 and the strap 26 in a particular extended position 100. The reel lock that maintains the position of the reel 24 and prevents further outward extension of the strap 26 can be automatically engaged via a tensioning mechanism or an internal actuator. The reel lock can also be manually engaged by the user to secure the position of the reel 24 and the strap 26 relative to the housing 16, the support structure 14 and the remainder of the ladder 12. After use of the ladder 12 is completed, the reel lock can be disengaged, and the strap 26 can be retracted back into the housing 16 and around the reel 24 using the biasing mechanism 28 contained within the housing 16. The housing 16 can then be rotated from the attaching position 20 back to the bypass position 22 and the ladder 12 can be retracted back to its original compact state.

According to various aspects of the device, the strap 26 is typically made of a vinyl or nylon fabric that is generally inelastic or substantially inelastic. The strap 26 is sturdy to account for the tension-type retaining force 110 that may be experienced when the securing device 10 is in use for securing the ladder 12 to the support structure 14. Also, the material of the strap 26 is be sturdy to withstand scratching, friction, and other abuse-type loads experienced when the strap 26 is extended and retracted from the housing 16 and also when the strap 26 is in use.
According to various aspects of the device, use of the securing device 10 for the ladder 12 can provide for an additional safety feature of the ladder 12 when used in the field. The securing device 10 is attached to the ladder 12 and is conveniently accessible for use in many conditions. The securing device 10 can be used in connection with a support structure 14, such as a utility pole, that the strap 26 can extend around to attach to the side rail 38 of the ladder 12. It is also contemplated that the securing device 10 can be used in connection with other support structures 14 that the strap 26 may not be able to extend around. The retainer 34 can include any one of various shapes that can be used to attach to larger support structures 14, such as walls, large posts and other structures. Where a larger support structure 14 is present, the retainer 34 can be used to attach directly to the support structure 14.
In addition, use of a ladder 12 in the field typically requires one or more people at the base of the ladder 12 to monitor the ladder 12 and prevent the ladder 12 from sliding or falling away from the support structure 14. Use of the securing device 10 can, in certain conditions, be used by a single person. When the ladder 12 is secured to the support structure 14 using the strap 26 of the securing device 10, the ladder 12 is prevented or substantially prevented from sliding away from the support structure 14. Accordingly, a single individual can use the ladder 12, in conjunction with the support device, when in the field. Typically, at least one other person will be present when using the ladder 12 as an additional layer of safety when using the ladder 12 in the field. The securing device 10 provides a primary safety feature to prevent the ladder 12 from sliding away from the support structure 14 while a person is on the ladder 12.

Utilizing the various aspects of the device, the securing device 10 for the ladder 12 can be used in the field to prevent slippage of the ladder 12 away from a support structure 14 or unintentional rotation or falling of the ladder 12 away from the support structure 14. The securing device 10 can provide users of the ladder 12 with peace of mind and confidence that the ladder 12 will be secured against the support structure 14.
