Description




BACKGROUND




In commercial construction, as well as in home improvement, ladders are frequently used to scale structures such as buildings. Repeated upward, downward and lateral movement of users may, at times, cause the ladder to slip or move. Such movement could potentially damage the structure or nearby property. More importantly, this sort of movement could cause the user to fall, resulting in serious injury. A device for securing a ladder, thereby preventing its movement, may therefore be desirable.




In securing a ladder, it is also important that the securing device be adaptable to a wide range of structures. For example, in some circumstances, it is preferable to fasten the securing device to the structure with a screw or nut and bolt assembly. However, in some circumstances, less invasive means of securing would be preferred. A device for securing a ladder that is adaptable to a wide range of structures, may therefore be desirable.




Another important consideration when using a ladder is the impact of the ladder on the structure. For example, when the structure being scaled is a building having rain-insulation devices, such as flashing drip-edges and gutters, these features can be significantly damaged by the placement of the ladder thereupon. A device that may minimize the impact of the ladder on the structure would therefore be desirable.




A number of prior patents disclose devices for securing ladders either to the ground, or to a nearby structure, thus preventing movement during use. Examples of these patents, each of which is incorporated by reference for its supporting teachings, are as follows:




U.S. Pat. No. 5,012,895 to Santos discloses adjustable extensions for enhancing the safety of a ladder. These extensions can be attached to the bottom ends of the side rails of the ladder so as effectively to adjust the lengths of such rails so that the ladder will not lean to either side, regardless of any difference in heights of the ground or support areas under such rails. Also, coupling cables couple the ladder to the wall of the building against which the ladder leans. The coupling cables connect the midpart of the ladder to a horizontal wall cable which is attached along and parallel to the wall of the building. The top of the ladder is stabilized against rolling to either the left or right and so that it can be positioned stably against irregular supports, such as windows, eaves, pitched roofs, pipes, etc., by means of stabilizing bars connected to its top and suitably shaped to mate with the irregular supports, and by extension arms which project out from the top of the ladder. Hand holds are attached to the extension arms.




U.S. Design Patent No. Des. 307,384 discloses an ornamental design for a ladder hook.




U.S. Pat. No. 4,765,439 to Kresmery discloses a device for retaining the upper end of a ladder to a building parapet wall or the like to securely, temporarily hold the ladder. The device is provided with a frame which is temporarily attached to the ladder and projects outwardly therefrom to extend over the building parapet wall. A clamp is attachable to the frame in various positions to entrap the parapet wall between the clamp and the ladder preventing a relative movement thereof.




U.S. Pat. No. 4,678,061 to Jordan, et al. discloses a ladder roof brace which includes adjustable means of engaging the rungs of a ladder, means of bearing against both sides of a roof over a ridge and means of engaging a gutter.




U.S. Pat. No. 2,685,957 to Schlesinger discloses a conveyor assembly for converting a ladder having side rails and rungs into a conveyor frame, a bucket guide, brackets and spring strips.




U.S. Pat. No. 1,252,224 to Bittner discloses a ladder support having a shank provided at its ends with oppositely disposed hooks which lie at the opposite sides of the shank, a clip adjustably mounted on the shank, means for securing the clip and a prong mounted on one end portion of the shank.




While the foregoing patents disclose improvements in the area of ladder safety, none of these patents disclose a ladder securing device that prevents movement of the ladder, which is also adaptable to a wide range of structures and minimizes the impact of the ladder on the structure.




SUMMARY OF THE ILLUSTRATED EMBODIMENT OF THE INVENTION




There is therefore provided a safety device, for securing a ladder to more than one structure type. The device includes a base, having one or more connection holes, designed to secure the safety device to a first structure type through the connection holes. The device also includes a securing section, coupled to the base section, designed to secure the safety device to a second structure type.




The device may optionally include a support, removably coupled to the base, designed to engage a front edge of a gutter, to prevent structural damage to the gutter when the ladder rests on the gutter. The device may also include a removable bracket portion, having one or more bracket connection holes, perpendicularly oriented to, and coupled to, the base, and designed to secure the safety device to a third structure type, through the bracket connection holes, when the support engages the front edge of the gutter.




A method of securing a ladder to a structure is also provided. In this method a securing device is provided. The securing device has a base, having one or more connection holes thereon, designed to secure the device to a first structure type; a hooking section, coupled to the base, designed to secure the device to a second structure type; and a buckle, rotatably coupled to the base.




It is determined whether the structure is the first or second structure type, and if the structure is the first structure type, the base is attached thereto. Alternatively, if the structure is the second structure type, the hooking section is attached thereto. A strap is coupled between the buckle and a ladder rung. Thus, the ladder is secured to the structure.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT(S)




Referring generally to

FIGS. 1-3

, there is shown a safety device


10


for securing a ladder to a structure


52


; Generally, the device


10


includes a base


11


. Coupled to the base


11


through common connection holes


25


(


a


)-(


c


) are support section


14


and bracket portion


16


. Also coupled to the base


11


is a securing section


12


and a buckle


20


.




The base


11


, securing section


12


, and bracket


16


are each designed to secure a ladder


45


(

FIG. 3

) to a structure


52


(

FIG. 3

) under at least three sets of circumstances. Specifically, the bracket


16


is well suited for securing a ladder


45


to a structure having rain gutters


37


. The base


11


can be used to secure a ladder


45


to a structure


52


having water insulating materials


40


, such as flashing. The securing section


12


is well suited to secure a ladder


45


to a structure


52


having a hookable edge


52


(


a


) (FIG.


6


), and where it may be desirable to avoid screwing or nailing the device


10


to the structure


52


.




With respect to the base


11


, as depicted in

FIG. 4

, the base


11


can be inserted underneath water insulating material such as flashing


40


. Through the connection holes


25


, one or more connectors


50


fastens the base


11


to the structure


52


. The device


10


is fastened by screws


50


driven through the flashing


40


, through the connection holes


25


, and into an underlying wood support


53


.




Once the device


10


is secured to the structure


52


, a strap


48


, coupled to the buckle


20


, may then be attached to a rung


47


on a ladder


45


(FIG.


3


). It is noted that, rather than creating new holes in the water insulating materials (e.g. the metal flashing


40


), the existing holes, already securing these materials to the structure


52


, can be utilized. In this manner, the ladder


45


can be secured to the structure


52


without significantly damaging the water insulating materials


40


. Moreover, the base


11


can include multiple connection holes


25


, thus better accommodating potentially diverse locations of existing holes in the water insulation


40


.




As can also be seen in

FIG. 4

, the drip edge


42


of the flashing


40


may be tucked in the space


43


between the base


11


and the securing section


12


. This configuration provides the added advantage of protecting the drip edge


42


from structural damage caused by a ladder


45


resting against it. The width of the space


43


can be adjusted to accommodate drip edges


42


of various sizes.




It is noted that while

FIG. 4

shows the present invention being utilized with a wood


53


and concrete


55


structure, the device


10


can be used with numerous structure types of various materials, including all concrete or all wood structures. It would be apparent to one skilled in the art that depending on the structure material, different types of connectors


50


would need to be used. For example, for an all concrete structure, concrete screws would be used.




In the embodiment shown in

FIGS. 1-6

, the securing section


12


is substantially hook shaped. This configuration allows the securing section


12


to engage a structure


52


by “hooking” it. For example, in

FIG. 6

is shown a second type of structure


52


having a hookable edge


52


(


a


). The securing section


12


closely engages the edge


52


(


a


), thereby securing the device


10


to the structure


52


.




Once the device


10


is secured to the structure


52


, a strap


48


may then be coupled between the buckle


20


and a ladder rung


47


, thereby securing the ladder


45


to the structure


52


.




As seen in

FIG. 3

, a support


14


can also be removably coupled to the base


11


. The support


14


is designed to engage a front edge


38


of a rain gutter


37


, to prevent structural damage to the gutter


37


when the ladder


45


rests on the gutter


37


. The support


14


can be coupled to the base


11


through a common connection hole


25


(


a


)-(


c


). In

FIG. 3

, this connection is made by a nut and bolt assembly


24


.




In one embodiment, connection hole


25


(


c


) is slotted. Thus, the support


14


is slidably coupled to the base


11


. The slidable coupling allows the support


14


to be positioned backwards or forwards depending on the width of the gutter


37


, or the gutter's position relative to the structure


52


. In other words, if the gutter


37


is unusually wide, or if it is positioned a distance away from the structure


52


, the nut and bolt coupling


24


can be loosened, and the support


14


slid forward relative to the base


11


. In this manner, the front end


15


of the support


14


can closely engage the front edge


38


of a wide variety of gutter


37


configurations.




As best seen in

FIG. 3

, when the support


14


is used, the device


10


can be attached to the structure


52


by a removable bracket


16


. In one embodiment, the removable bracket


16


is coupled to the base


11


and support


14


through common connection holes


25


(


a


)-(


c


). The bracket portion


16


has a perpendicular orientation relative to the base


11


. The bracket


16


has one or more bracket connection holes


26


(

FIGS. 1-2

) through which the device


10


can be secured to a third structure type having rain gutters


37


. The bracket


16


is primarily needed when the support


14


is being used to prevent gutter


37


damage caused by the ladder


45


.




The buckle


20


, as noted above, can be rotatably coupled to the base


11


. Typically, a strap


48


is attached to the buckle


20


. The strap


48


is also coupled to a rung


47


on a ladder


45


. The straps


48


could be fastened by any conventional means. For example, in

FIGS. 1-6

, the straps are shown as having strap buckles


49


.




In

FIGS. 1-4

and


6


, a separator


18


is shown coupled between the base


11


and securing section


12


. In this embodiment, the separator


18


is coupled to the base


11


and securing section


12


by a welded screw


22


through common connection holes


28


(


a


)-(


c


). The separator


18


provides, among other advantages, a means to secure the buckle


20


to the base


11


. It is noted that, in other embodiments, additional separators


18


can be used.





FIG. 5

illustrates the operation of the device


10


on a structure


52


having a rain gutter


37


. As is evident from the figure, the bracket portion


16


is secured to the structure


52


through bracket connection holes


26


. A strap


48


then couples the ladder rung


47


to the buckle


20


, which, along with the bracket


16


, is coupled to the base


11


.




Variations of the Invention




In

FIGS. 1-4

and


6


, the hooking end


44


of the securing section


12


is a rounded protrusion. However, it is noted that several configurations could accomplish the “hooking” action, and are considered to be within the scope of the present invention. For example, rather than being rounded, the hooking end


44


could be an angled protrusion.




It is also noted that the end


15


of the support


14


could also be configured in a variety of ways. In the embodiments shown in

FIGS. 1-3

, the end


15


is substantially hook-shaped. However, the end


15


could simply terminate without the hook. Additionally, the end


15


could include a ball, or other enlargement, that would aid in snug engagement of the gutter's edge


38


. Numerous other configurations would be apparent to one skilled in the art.




It is also noted that, in

FIGS. 1-4

and


6


, the base


11


and securing section


12


are shown as one continuous piece of material, separated by a bend in the material. However, it is not necessary that the base


11


and securing section be forged from the same piece. For example, in one embodiment, the base


11


is one piece and the securing portion


12


is welded thereto. Numerous other means of coupling the base


11


to the securing section


12


would be apparent to one skilled in the art.




In

FIGS. 1-4

and


6


, the buckle


20


is shown situated in the bend between the base


11


and the securing section


12


. However, the buckle


20


could be coupled to the base


11


in any number of ways that would be apparent to one skilled in the art.




Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiments of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function, manner of operation, assembly, and use may be made without departing from the principles and concepts set forth herein.
