This invention pertains generally to a safety device for protecting a pool ladder from unintended use by a small child, and more particularly to a dual purpose safety device for preventing small children from climbing a ladder used to access an aboveground pool and for use as an emergency rescue flotation device.
Aboveground swimming pools pose a significant threat to small children and toddlers that cannot swim. These pools frequently employ a ladder that is set up against or attached to the side of the pool for use in gaining access to the pool. These ladders are easily accessible by children. Toddlers and other small children are typically able to climb the ladder and enter the pool even without adult assistance. As the pools are semi-permanent, this creates a significant hazard for small children. If the pool owner does not immediately remove the ladder after use, it remains as a temptation for children to climb. Additionally, neighborhood children could easily find their way into the pool and accidently drown.
Consequently, there exists a need for a safety device designed to prevent a child from easily accessing and climbing the ladder of an aboveground swimming pool. The present invention discloses a device for ensuring that toddlers and other small children are unable to easily climb the ladder, thereby restricting the child's access to the pool. The safety device is also useful as an emergency flotation device in the event that anyone using the pool begins to struggle or drown.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed invention. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one aspect thereof, comprises a safety device designed for use in preventing unsupervised toddlers and small children from easily climbing an aboveground pool ladder. The safety device comprises a body portion capable of flotation and an attachment portion. The attachment portion is typically a pair of hook elements extending out of a top of the body portion. The pair of hook elements are used to engage a rung on the above ground pool ladder so that the body portion restricts access to a plurality of lower rungs, thereby preventing a child from easily climbing the ladder once the safety device is in place.
Furthermore, in the preferred embodiment of the invention, the pair of hook elements are adjustable so that the safety device can accommodate different sized ladders. A first side rail and a second side rail extend rearward from the body portion to help keep the safety device centered on the ladder. Additionally, in the event of a water emergency, the safety device is useable as an emergency flotation device for rescue. The safety device extends the reach of a rescuer from a safe position without the need to enter the water during the rescue.
To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative of the various ways in which the principles disclosed herein can be practiced and all aspects and equivalents thereof are intended to be within the scope of the claimed subject matter. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter.
The present invention discloses a safety device for preventing small children from inadvertently entering an aboveground pool via an above ground pool ladder. The safety device comprises a body portion, typically made from molded plastic allowing the safety device to float. To limit access to the aboveground pool ladder, an attachment portion allows the safety device to hang from a rung of the aboveground pool ladder so that the body portion substantially covers a plurality of lower rungs, thereby restricting access to the pool via the ladder while the safety device is in place. Furthermore, in the event of a water emergency, the safety device is useable as an emergency flotation device that extends the reach of a rescuer from a safe position outside of the pool.
Unless built into a deck, access to an aboveground pool is normally by means of an aboveground pool ladder 20. The aboveground pool ladder 20 typically comprises a pair of rails 30 and a plurality of rungs 40. The pair of rails 30 hang or extend over a rim of the above ground pool to assist in entry and egress.
Referring initially to the drawings,
Generally, the body portion 102 is substantially rectangular in shape with rounded edges. However, any shape that may protect the aboveground pool ladder 30 may be used, such as an embodiment where the body portion 102 is generally ovoid or shaped like a surfboard. When rectangular in shape, the body portion 102 typically is approximately between 1/8th and one inch in thickness. Generally the body portion 102 is approximately between 30 and 42 inches in length and approximately between 14 and 20 inches in width. However the dimensions of the body portion 102 are chosen to correspond to the dimensions of the aboveground pool ladder 20 so they may vary depending on the dimensions required. For example, to fit a common generic aboveground pool ladder, the body portion 102 would be approximately 36 inches in length and approximately 18 inches in width. These dimensions would allow several of the plurality of rungs 40 to be protected across an entire width of the aboveground pool ladder 20.
The body portion 102 comprises a first side rail element 104 and a second side rail element 108. As illustrated in
As illustrated in
The body element 102 further comprises a top 112 of the body portion 102 and a bottom 118. The bottom 118 may rest on the ground or may be elevated above ground level depending on the preference of the user. The attachment portion 124 extends from or out of the top 112 of the body portion 102 and engages one or more of the plurality of rungs 40, thereby allowing the body portion 102 to cover more than one of the lower plurality of rungs 40. The attachment portion 124 generally comprises a first hook element 126 and a second hook element 128. Both the first hook element 126 and the second hook element 128 each comprise a cane or hook shaped shaft constructed of plastic or metal. The cane or hook shaped shaft may be embedded or otherwise affixed to the top 112 of the body portion 102, or may be attached to the back 122 of the body portion 102. For example, the first hook element 126 and the second hook element 128 may be permanently molded into the top 112 of the body portion 102 so that the safety device 100 remains consistently at a fixed length.
Alternatively, the first hook element 126 and the second hook element 128 may be slidably adjustable. The body portion 102 may further comprise a first channel 114 and a second channel 116 embedded within the body portion 102 extending inward from the top 112 of the body portion 102. The first channel 114 and the second channel 116 may be smooth bore plastic tubes, screw threaded plastic tubes, bore holes, free space, and the like. The embodiment illustrated in
The first hook element 126 and the second hook element 128 are generally slideably adjustable within the first channel 114 and the second channel 116 so that a user may easily change the overall length of the safety device 100. For example, the body portion 102 may substantially restrict access to at least a lower two of the plurality of rungs 40 while the first hook element 126 and the second hook element 128 engage a top rung of the aboveground pool ladder 20 holding the safety device 100 in position. However, the first hook element 126 and the second hook element 128 are each fixable at a plurality of positions within the first channel 114 and the second channel 116 so that the safety device 100 may be usable on a variety of different sized ladders. The first hook element 126 and the second hook element 128 may frictionally engage the first channel 114 and the second channel 116. Alternatively a plurality of position fixing elements 130 as seen in
When in use the first hook element 126 and the second hook element 128 typically face rearwardly toward the aboveground pool extending over and engaging one of the plurality of rungs 40, The first hook element 126 and the second hook element 128 may comprise safety or snap back hooks so that the first hook element 126 and the second hook element 128 can pivot about an axis when not in use. Additionally, the entire attachment portion 124 may be removable. As such, the first hook element 126 and the second hook element 128 may be completely detached and removed from the first channel 114 and the second channel 116. For example, as the body portion 102 floats on water, the safety device 100 may be used without the first hook element 126 and the second hook element 128 as a floating toy or rescue device.
