DETAILED DESCRIPTION

[0026] Referring now to FIG. 1, a clamping device, generally designated 10 is provided for securing a ladder 12 to a structure 14. As is known in the art, the ladder 12 includes a first rail 16, a second rail 18, and a plurality of vertically spaced, parallel rungs 20 secured to the rails 16 and 18. As illustrated, the structure 14 includes a gutter 22 and fascia boards 24. However, the clamping device 10 is configured for securing the ladder 12 to a broad variety of structures 16, including, but not limited to, walls and structures made of wood or brick.

[0027] The clamping device 10 is provided with a housing 26. The housing 26 includes a first, ladder end 28, and a second, building end 30, best seen in FIG. 2. As shown in FIG. 3, the housing 26 defines an internal cavity 32. Disposed in the internal cavity 32, a housing track 34 is formed by two parallel, vertically spaced ribs 36.

[0028] Referring now to FIGS. 2 and 3, the clamping device 10 includes a clamp 40, which is partially enclosed in the internal cavity 32 of the housing 26. The clamp 40 includes a clamp housing end 42 disposed in the internal cavity 32 of the housing 26, and an opposing clamp grip end 44 that extends from the housing 26 at the ladder end 28. The clamp 40 is designed such that it laterally reciprocates along the vertically spaced ribs 36 that form the housing track 34. To allow for this reciprocation, the clamp 40 includes a clamp track 46 defined by an upper surface 48 and a lower surface 50 of the clamp 40 that extend from the housing end 42 to the grip end 44. The clamp track 50 engages with the housing track 34 such that the clamp 40 laterally reciprocates along a longitudinal axis 52 defined by the clamp 40.

[0029] The clamping device 10 is further provided with a fascia wedge 60 disposed at the grip end 44 of the clamp 40 for releasable attachment to the structure 14. The fascia wedge 60 generally extends perpendicularly from the longitudinal axis 52 of the clamp 40. In order to create a strong connection between the clamping device 10 and the structure 14, the fascia wedge 60 includes an upper wedge surface 62 having a first gripping surface 64 and a lower wedge surface 66 having a second gripping surface 68. As shown in FIG. 2, the second gripping surface 68 of the fascia wedge 60 directly contacts an outer surface of the structure 14. Optionally, the first gripping surface 64 of the fascia wedge 60 is positioned such that it is in contact with the gutter 22, as shown in FIG. 2. The first gripping surface 64 is also preferably positioned such that it is in contact with an inner surface of the facia board 24, or any other suitable surface on the structure 14.

[0030] A fascia wedge opening 70, best seen in FIG. 3, is formed on the fascia wedge 60 and extends from the upper wedge surface 65 to the lower wedge surface 68. The fascia wedge opening 70 is formed in the fascia wedge 60 so that a fastener 72, preferably a threaded fastener, may optionally be driven into the structure 14 through the fascia wedge 60 to provide strengthen the connection between the fascia wedge 60 and the structure 14. When the first gripping surface 64 of the fascia wedge 60 is not in contact with any surface of the structure 14, the fastener 72 is particularly useful in creating a strong connection between the fascia wedge 60 and the structure 14.

[0031] In order for the clamping device 10 to releasably engage with the ladder 12, a ladder hook 74 is disposed at and extends proximate to the ladder end 28 of the housing 26. As seen in FIG. 1, the ladder hook 74 is configured to secure around the first rail 16 of the ladder 12. The ladder hook 74 is provided with a first end 76, best seen in FIG. 3, disposed within the housing 26, a second hooked end 78, and an intermediate portion 80 extending the between the first end 76 and the second hooked end 78 of the ladder hook 74. In order to accommodate ladders 12 of different sizes, the ladder hook 74 is adjustable laterally such that the intermediate portion 80 slides into the housing 26 at an oblique angle relative to the axis 52. When a ladder hook release tab 82 is actuated by a user, the ladder hook release tab 82 is moved to a depressed position and the ladder hook 74 is laterally adjusted such that the intermediate portion 80 slides relative to housing 26 until the ladder hook 74 is in the desired position. The ladder hook release tab 82 is biased to a locked position, as shown in FIG. 3, by a ladder hook biasing element 83. When the ladder hook release tab 82 is in the locked position, the ladder hook 74 cannot be moved laterally.

[0032] Additionally, the ladder hook 74 is rotatably adjustable such that it rotates about an axis concentric with the intermediate portion 80 of the ladder hook 74.

[0033] In addition to being adjustable laterally and rotatably as described above, the ladder hook 40 also include a ladder hook adjustment mechanism 84, as shown in FIG. 4. The ladder adjustment mechanism 84 allows the clamping device 10 to accommodate ladders 12 of varying rail thicknesses. In FIG. 4, the ladder adjustment mechanism 84 locks into and is adjustable between slit indentations 86 on the second hooked end 78 of ladder hook 74. However, alternative ladder adjustment mechanisms 84 are contemplated, such as a threaded mechanism, tether, or elastic member, among others. As best seen in FIG. 4, the first rail 16 and the second rail 18 may each be formed of multiple rails. This rail configuration is known in the art, for example with sliding extension ladders. As shown in FIG. 4, the clamping device 10 is compatible with such sliding extension ladders and is also compatible with a number of different types of ladders.

[0034] Referring again to FIGS. 1-3, a user operates the clamping device 10 and applies clamping force with an actuator 88, which is provided with a handle 90. The handle 90 has a stationary grip portion 92 and a lever 94, both disposed on the housing 26. The lever 94 is pivotably attached to the housing 26 and is movable between a rest position, as shown in FIG. 2, and a retracted position. The lever 94 pivots about pivot point 95 on housing 26, which is located above the upper surface 48 of clamp track 46. When a user operates the clamping device 10 and moves the lever 94 from the rest position to the retracted position, a biasing element 96 pushes the lever 94 back towards the rest position. The biasing element 96 is a spring or any other suitable mechanism for biasing the lever 94 to the rest position. The lever 94 also includes a clamp opening 98, which is described in greater detail below. When the clamping device 10 is actuated, the actuator 88 allows for lateral movement of the clamp 40 and the fascia wedge 60 relative to housing 26.

[0035] During operation, a user employs the lever 94 to actuate the movement of the clamp 40 towards the first ladder end 28 of the housing 26. The clamp 40 is disposed within and engages with the clamp opening 98 of the lever 94. As such, the clamp opening 98 is dimensioned so that as the lever 94 is actuated from its rest position to its retracted position, an inner surface 100 of the clamp opening 98 comes into contact with and engages the lower surface 50 of the clamp 40. As the lever 94 is actuated, this engagement between the inner surface 100 of the clamp opening 98 and the lower surface 50 slides the clamp 40 towards the first ladder end 28 of the housing 26. This movement draws the fascia wedge 60 towards the ladder hook 74, creating a clamping force that acts on the ladder 12. This clamping force secures the ladder 12 to the structure 14. The lever 94 is actuated repeatedly by the user until sufficient clamping force is acting to secure the ladder 12 to the structure 14.

[0036] Once a user is finished using clamping device 10, a clamp track release tab 102 allows for the clamp 40 to be slid away from the ladder end 28 of the housing 26. The clamp track release tab 102 has a release tab opening 104 and is pivotally disposed on the housing 26 proximate the second building end 30. The clamp track 46 is slidably disposed within a release tab opening 104 and engages with an inner surface 106 of the release tab opening 104. The clamp track release tab 102 pivots from an oblique position, as shown in FIG. 3, to a normal position, in which the clamp track release tab 102 is perpendicular to the axis 52. When the clamp track release tab 102 is in the oblique position, the inner surface 106 of the release tab opening 104 is in contact with the clamp track 46 such that the clamp 40 is prevented from moving away from the ladder end 28 of the housing 26. This allows for a user to gradually increase the clamping force acting on the ladder 12 by repeatedly actuating the lever 94 without the clamp 40 sliding away from the ladder end 28 of the housing 26. When the clamp track release tab 102 is actuated by the user into the normal position, the inner surface of the release tab opening 104 is no longer in contact with the clamp track 46, and the clamp 40 may be freely moved away from the ladder end 28 of the housing 26. A similar biasing member such as the biasing element 96 is used to bias the clamp track release tab 102 from the normal position to the oblique position.

[0037] The clamping device 10 is further provided with a gutter hook 108, which abuts against the gutter 22 of the structure 14 to provide additional stability. The gutter hook 108 is fixed to the housing 26 and pivots between a deployed position, as shown in FIG. 2, and a retracted position, as shown in FIG. 6. In the deployed position, the gutter hook 108 extends from the housing 26 at an oblique angle relative to the axis 52 defined by the clamp 40, as seen in FIG. 3. In the retracted position, the gutter hook 108 is pivoted from the deployed position such that the gutter hook 80 rests against the housing 26 and is substantially parallel to the axis 52 defined by the clamp 40. As best seen in FIG. 2, the engagement surface 110 of the gutter hook 108 is indented to strengthen the engagement between the gutter 22 and the clamping device 10. The clamping device 10 provides sufficient clamping force to secure the ladder 12 to the structure 14 regardless of whether the gutter hook 108 is in the deployed or retracted position.

[0038] Referring now to FIGS. 5 and 6, the clamping device 10 is further shown with the clamp 40 in both the extended and retracted position, as well as the gutter hook 108 in both the deployed position and retracted position. FIG. 6 shows the clamping device 10 with the clamp 40 in the retracted position and the gutter hook 108 and the ladder hook 74 in the retracted position. With the clamping device 10 in this position shown in FIG. 6, the clamping device is more compact and better suited for transportation and storage when not in use.

[0039] While a particular embodiment of the present ladder fascia clamp and lock has been described herein, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
