Attachable ladder stability device

[0001] The present invention relates to ladders, and more particularly, to ladder attachments that stabilize leaning ladders.

[0002] Applicant is not aware of any attachable ladder stability device having the novel features of the present invention.

[0003] The invention consists of a first arm assembly, a first foot assembly, and a second arm assembly, and a second foot assembly. The device also includes a tether assembly, a first telescopic assembly, and a second telescopic assembly.

[0004] The first arm assembly includes a first arm upper bar and a first arm lower bar, while the second arm assembly includes a second arm upper bar and a second arm lower bar. Both arm assemblies can be mounted onto a ladder assembly, which includes ladder rails, ladder direct rung-to-rail connections, and ladder rungs. The ladder rungs are hollow and have the ladder direct rung-to-rail connections at respective ends.

[0005] The first arm assembly and the second arm assembly attach to the ladder assembly. A first ladder rung secures the first arm upper bar and the second arm upper bar, while a second ladder rung secures the first arm lower bar and the second arm lower bar. The first arm upper bar and the second arm upper bar are inserted into a first ladder direct rung-to-rail connection, and the first arm lower bar and the second arm lower bar are inserted into a second ladder direct rung-to-rail connection.

[0006] The tether assembly further secures the first arm assembly and the second arm assembly to the ladder assembly. The tether assembly includes a tether connection, a tether safety pin, and a tether tension arm, and connects the first arm assembly and the second arm assembly. The first arm assembly includes a first arm through hole, and the second arm assembly includes a second arm through hole to attach the tether assembly.

[0007] The first arm assembly and the second arm assembly can also mount onto a roof, which includes a roof upper surface and a roof side wall. The first foot assembly and the second foot assembly interface with the roof upper surface. Each foot assembly includes a foot pad and can pivot on its respective arm assembly to interface with angles defined by the roof upper surface.

[0008] The roof assembly includes a gutter base and a gutter front wall, which define a channel cavity, whereby, the first telescopic assembly and the second telescopic assembly are secured by the channel cavity. The first telescopic assembly and the second telescopic assembly each include a telescopic hollow post, telescopic through holes, and a telescopic adjustable support that allows them to adjust to lengths. The first telescopic assembly and the second telescopic assembly extend downward to the gutter front wall and the gutter base. They work in conjunction with the first foot assembly and the second foot assembly, to support in opposing directions to stabilize and prevent the ladder assembly from sliding backward or moving in longitudinal or horizontal directions.

[0009] It is therefore one of the main objects of the present invention to provide a stability device that stabilizes a ladder assembly.

[0010] It is another object of this invention to provide a stability device that secures to a ladder assembly.

[0011] It is another object of this invention to provide a stability device that can interface with variable structures and surfaces to provide stability for a ladder assembly.

[0012] It is another object of this invention to provide a stability device that is quick and easy to install.

[0013] It is another object of this invention to provide a stability device that is quick and easy to uninstall.

[0014] It is another object of this invention to provide a stability device that is volumetrically efficient for carrying, transporting, and storage.

[0015] It is another object of this invention to provide a stability device that can be readily assembled and disassembled without the need of any tools.

[0016] It is another object of this invention to provide a stability device which is of a durable and reliable construction.

[0017] It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.

Ladder rungs 126 are hollow and comprise ladder direct rung-to-rail connections 124 at respective ends. First arm assembly 30 and second arm assembly 30′ attach to ladder assembly 120. First ladder rung 126 secures first arm upper bar 34 and second arm upper bar 34′, and second ladder rung 126 secures first arm lower bar 54 and second arm lower bar 54′, whereby first arm upper bar 34 and second arm upper bar 34′ are inserted into first ladder direct rung-to-rail connections 124, and first arm lower bar 54 and second arm lower bar 54′ are inserted into second ladder direct rung-to-rail connections 124. In a preferred embodiment, the first ladder direct rung-to-rail connections 124 and second ladder direct rung-to-rail connections 124 are adjacent to one another without any other ladder direct rung-to-rail connections in between them.

[0036] In one embodiment, roof assembly 150 comprises roof upper surface 152, roof side wall 154, and roof support wall 156. In use, first foot assembly 60 and second foot assembly 60′ interface with roof upper surface 150, whereby first foot assembly 60 and second foot assembly 60′ pivot to adjust to various roof upper surface 152 angles.

[0037] In another embodiment, roof assembly 150 may also comprise a gutter system having gutter side wall 158, gutter front wall 160, gutter base 162, and channel cavity 164. If roof assembly 150 also comprises the gutter system having gutter side wall 158, gutter front wall 160, and gutter base 162, first telescopic assembly 90 and second telescopic assembly 90′ interface with gutter front wall 160 and gutter base 162. Gutter front wall 160 and gutter base 162 define channel cavity 164, whereby first telescopic assembly 90 and second telescopic assembly 90′ are secured. First telescopic assembly 90 and second telescopic assembly 90′ vary in length. First telescopic assembly 90 and second telescopic assembly 90′ extend downward towards gutter front wall 160 and gutter base 162 and lock in place when first push button 104 and second push button 104′ protrude from first through hole 98 and second through hole 98′, respectively. First telescopic assembly 90 and second telescopic assembly 90′, in conjunction with first foot assembly 60 and second foot assembly 60′, support in opposing directions to prevent ladder assembly 120 from sliding backward or moving in longitudinal and lateral directions. First and second telescopic arm assemblies, 90 and 90′, adjust in length to interface with various gutter sizes and designs.

[0038] In a preferred embodiment, first and second arm assemblies 30 and 30′, respectively, are installed on an extension ladder. More specifically, first and second arm assemblies 30 and 30′ are installed on the part of an extension ladder that extends.
