BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to accessories for swimming pools and spas, and in particular relates to steps for use by animals to exit a body of water.
2. Discussion of Related Art
Traditionally, pools have built-in steps or ladders secured to the edge of the pool to assist humans entering and exiting the pool. Some pools have human scaled steps molded into the shallow end and a climb out shelf built into the deep end. These are all designed for use by human beings and are built to a corresponding scale. Existing pools, particularly in private homes, may not have a means for entering and exiting the pool that is easily used by animals. For example, animals cannot climb ladders; Small animals that enter the pool either on purpose or by accident have difficulty exiting the pool due to the relative deepness of human scale steps and climb out shelves.
Devices exist as an inadequate remedy to this dilemma. For example, U.S. Pat. No. 6,643,879 to Davis is a plastic ramp with no side walls that is attached by ropes to the surface of the pool deck and floats in the water at an angle. However, when the animal gets on a ramp to exit the pool, the weight of the animal will force the floating end farther into the water thus increasing the angle of the ramp making it more difficult and stressful for the animal to exit the pool. It is also difficult for the animal to maintain its balance, which can cause the animal to fall back into the water via the open sides. Thus, exhaustion and fear can cause the animal to resist using the device and drown.
Similarly, spas, or hot tubs, have deep steps on the inside of the tub with a scale that is difficult or impossible for small animals to navigate. Animals may enter a spa of this type and not be able to climb out. They circle the spa swimming frantically until they die. Adding a ramp or pool steps would not solve this problem as they would not fit within a typical spa to provide a means of escape for a small animal.
Thus, there is a need for a device that can be easily added to a pool or spa that can enable animals to safely and confidently exit pools or spas.
BRIEF SUMMARY OF THE INVENTIONAspects of embodiments of the invention relate to providing a stable structure that can be secured to a pool or spa edge to provide easy exit for animals.
Another aspect of embodiments of the invention relates to providing a structure that is compatible with a water setting and can be used in a pool or spa.
An additional aspect of embodiments of the invention relates to providing a structure that is quick and simple to remove from the water in a pool or spa for maintenance, cleaning or water sports.
This invention is directed to a stair assembly for mounting to a pool edge. The assembly includes a hanging platform having a mounting plate designed to be supported on a generally horizontal surface of the pool edge and a step support plate extending generally perpendicular to the mounting plate configured to hang from the pool edge. Steps extend outwardly from the step support plate, with each step being defined by a riser and a tread. Each tread extends outwardly to a position horizontally offset from an adjacent step. A connector is supported by the mounting plate for connecting the mounting plate to the pool edge. A stop mechanism may be provided to abut the pool edge to restrict movement of the step support plate in a horizontal direction.
The invention is further directed to a stair assembly for connection to an edge of a body of water that allows animals to exit the water. The assembly includes an angled platform configured to rest on the edge of the body of water and to hang over the edge toward the water. A connector is associated with the angled platform to secure the angled platform to the edge of the body of water. A support wall extends from the angled platform that supports a plurality of steps. A stop mechanism is associated with the support wall to limit movement of the support wall with respect to the edge of the body of water when the animal climbs onto a step.
The invention is also directed to a method of using a stair assembly to provide egress to an animal in a body of water, including first providing a stair assembly that includes a mounting section having a ledge that is configured to rest on a pool edge and a step section. The step section includes a side wall with at least one tread extending from the side wall at a level lower than the ledge of the mounting section. The method includes mounting the stair assembly on the edge of the pool by securing the ledge to the side of the pool such that the at least one tread is at or beneath the surface of the body of water. Finally, the method includes training a pet to use the stair assembly to exit the body of water, including enticing the pet toward the tread and encouraging the pet to climb from the water to the pool edge using the stair assembly, and repeating until the pet uses the stair assembly without assistance or encouragement.
These and other aspects of the invention will become apparent when taken in conjunction with the detailed description and appended drawings.

In the drawings, like reference numerals indicate corresponding parts in the different figures.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSThis invention is directed to an accessory that is usable in a body of water, especially a contained body of water that has side walls. For ease of reference, the body of water referred to herein is generically termed a “pool.” However, it should be understood that the term “pool” is intended to encompass various types of aquatic structures, including swimming pools, spas, hot tubs, whirlpools, soaking tubs, and even man-made shore lines (retaining walls.) The invention could also be used with any ledge adjacent a body of water, such as on a boat or a dock.
Referring to
Steps formed as a series of treads 20 and 22 extend from the side wall 18. Of course, any number of steps, including just one, can be provided. As is conventional, each step is formed of a tread and a riser. The treads 20 and 22 can have a traction surface 24 provided thereon to avoid slipping during use. If desired, perforations or other means to allow water to pass through the step unit can be provided to avoid air locks beneath the step section 16 and prevent it from floating. In the design shown in
Preferably, the stair assembly 10 is formed from a durable material that can withstand sun, water, and chemical exposure. Injection molded plastics would be suitable for this assembly. For example, the stair assembly 10 may be formed of a UV stable material such as PVC (polyvinyl chloride). Other suitable materials include ABS, PET, RPET, and PP/SciOx, for example. Preferably, the material will be resistant to commonly used pool chemicals, such as chlorine and bromine. Also, the material should be heavy so that it tends to sink and remain submerged with respect to the water line W. So, the specific gravity of the selected material should be greater than 1.0. The treads can offer a solid or textured surface, if desired. The assembly, particularly the steps, can also be formed with a series of open ribs or holes to provide strength and offer drainage, if desired. Of course, any structural support and/or drainage structure, especially those known in the field of injection molding, can be used.
The mounting section 14 is formed as a plate that fits on the edge of the pool or spa. In this embodiment, the step support section 18 is formed as two plates connected by a hinge 26. While any known hinge 26 can be used, preferably the hinge 26 is formed as a flexible strip of material that can be adhesively secured to both plates and create a durable secure connection.
The hinge 26 allows the step section 16 to be positioned in three different positions. The “in-use” position, as seen in
A connector 28 is secured to the bottom surface of the mounting section 14. The connector 28 preferably includes an adhesive layer that securely attaches the mounting section 14 to the edge 12. The adhesive layer 28 can be a pressure sensitive adhesive strip, for example. Of course, other types of connectors can be used, including hook and loop fasteners, such as Velcro, or a bolt, pin or keyed connector. The adhesive layer 28 can be applied during installation or, preferably, be supplied with the stair assembly 10. A release sheet 30 is provided to cover the adhesive layer 28 prior to installation. The release sheet 30 is secured over the adhesive layer 28 and folded over itself, as seen in
As seen in
If the stair assembly 10 is not precisely positioned on the surface, the hinge 26 will accommodate any misplacement by allowing the step section 16 to hang and swing from the mounting section 14. Thus, it is not necessary to precisely position the unit to realize an effective installation.
As seen in
Steps 36 are formed as a series of treads having a successively deeper step to form stairs. In this case, the steps 36 are connected to the step section 35 via slots 37 and threaded fasteners 38 to allow adjustment of the height of the steps 36. As seen in
The connector 52 is provided to attach the mounting plate 44 to the edge 12. In this case, the connector 52 is a hook and loop fastener, as seen in
The interlocking mounting plate 70 is seen in detail in
First portion 72 has a pair of fingers 78 that extend outwardly and define grooves 80, as seen in
In use, the stair assembly 10 is installed on a pool or spa and made available to a pet for egress from the water in the in-use position. For swimming pools, the stair assembly should be placed at the farthest point from any existing steps. If the pool has corners, the stair assembly should be placed as close to the corner as possible since pets tend to follow the walls of the pool to escape. The area where the stair assembly is located should be clear of any obstructions that might prevent the pet from accessing the steps. For spas, the stair assembly should be placed in a location that provides the pet with an unobstructed safe landing area.
This invention also includes the steps of training the pet to recognize and use the stair assembly as a pet would not normally know that the stair assembly can be used to escape from the interior of the pool or spa. Training the pet involves the following steps.
After the stair assembly is properly attached to the pool edge, such as the pool deck, place the pet in the pool facing the stair assembly and within easy swimming distance. It is best to start a few feet away. Someone then stands over the stair assembly and calls the pet with a favorite treat. Some pets will need help initially, but most pets will swim to the stair assembly and climb up to receive the treat. This exercise should be repeated with the distance between the pet and the steps extended each time until the pet tires or easily exits the pool. Repeat this exercise several days in a row. When the pet appears confident when using the stair assembly, place the pet in the water and determine if the pet can exit without the treat inducement or encouragement from a person. Most pets will learn to use the stair assembly by the third time and by day three are comfortable exiting the body of water using the stair assembly.
Obviously, the stair assembly can be made any size. The steps could be molded in various shapes to accommodate certain standard pool or spa designs or alternatively could be custom designed to accommodate special pools or particular intended applications.
Any of the connectors described herein can be used with any of the step, ledge or side wall designs described herein. Also, the various assemblies may be used with or without the support legs.
Various modifications can be made in my invention as described herein, and many different embodiments of the device and method can be made while remaining within the spirit and scope of the invention as defined in the claims without departing from such spirit and scope. It is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
