The present invention relates to a safety device for stairways.
As is known, stairways or steps facilitate permitting persons to ascend or descend levels of a building. Occasionally, it is necessary to warn or alert persons of the stairways or steps to prevent tripping or falling or of other hazards. Signage or devices are often employed to provide warnings. However, the known devices are not reusable and cannot be adapted to stairways or stairs with varying surfaces. For example, it may be difficult to employ a warning device or signage on stairway surfaces that are carpeted or concrete. Additionally, the known warning devices typically get worn or damaged or can get dirty and are not easily cleaned or replaced without damaging the underlying surface. Therefore, it can be expensive to provide different or replacement warning devices for varying surfaces as well as maintain a cleanliness of the devices. Additionally, it is especially difficult for persons with impaired depth perception to properly see the stairways or warning devices.

The following detailed description and appended drawings describe and illustrate various embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner. In respect of the methods disclosed, the steps presented are exemplary in nature, and thus, the order of the steps is not necessary or critical.
The first layer 14 may be formed from any suitable material such as paper, a polymeric material, a metal, a composite material, or the like. The first layer 14 includes visual indicia 18 on a surface 15 thereof to alert those with depth perception issues of a hazard. The indicia 18 could be bright colors 21 (as indicated by the diagonal lines), numbering 20, lettering 22, symbols 24, surface features 26 such as protrusions or etching or indentations, or other indicia as desired to assist persons with minimized or impaired depth perception. The indicia 18 provides visual stimuli for the persons with the impaired depth perception.
The second layer 16 is formed from a polyurethane material. For example, the polyurethane is a polyurethane gel elastomer having a tacky or sticky feel when contacted by a user. As described herein, the polyurethane gel elastomer is a class of very soft, according to the Durometer scale, casting resin material such as the polyurethane gel elastomer manufactured by Northstar Polymers of Minneapolis, Minn. Although, other polyurethane materials can be employed as desired. The polyurethane gel elastomer is a material that is washable and reusable. As used herein, washable means capable of being cleaned with liquids or cleaning chemicals without deterioration and without losing the tactile properties that facilitate removable adhesion of the device 10 to the structure 100. Reusable means capable of use and adaptable for use in in different locations or environments and removable for use from one location to another location without damage or wear.
The second layer 16 may include an attachment means 28 disposed on at least a portion of a surface 17 thereof configured for removable attachment to the structure 100. For example, the attachment means 28 can be an adhesive applied to a material (not shown) with the material disposed on the surface 17. In other examples, the attachment means 28 can be a hook and loop system, a plurality of pins or hooks, a malleable material configured to adhere to surfaces of the structure 100 or any other attachment means as desired. The second layer 16 can be monolithically formed with the first layer 14 or separately formed from the first layer 14 and attached thereto by attachment means such as an adhesive, hook and loop system, rivets, or any other attachment means configured to attach the first layer 14 to the second layer 16. Whether the attachment means 28 covers an entirety of the surface 17 or a portion thereof, the attachment means 28 may be adapted to be removably coupled or adhered to the surface 17 of the second layer 16. In this way, the attachment means 28 may be removed from the device 10 during a cleaning thereof or for replacement with a new attachment means 28. It is understood that the device 10 will function as intended and anticipated herein with or without the attachment means 28.
As shown, the safety device 10 is substantially rectangular. However, it is understood the safety device 10 can be any shape as desired. The safety device 10 can be folded or bent along an edge line 30 disposed intermediate opposing sides 32 of the safety device. The edge line 30 facilitates folding or bending of the safety device 10 for a pair of surfaces that are non-planar with respect to each other.
The safety device 10 is configured to be used on any type of surface including carpet, hardwood, vinyl, tile, concrete, compositions thereof, or any other type of surface commonly employed with structures. As a result, the safety device 10 can be removably adhered to one surface and then moved from that surface to and removably adhered to another another without compromising the integrity or purpose thereof.
The safety device 10 is shown coupled to the stairwell 200 according to various examples. According to one example, as shown with respect to the first step 1, the safety device 10 is coupled to a horizontal surface 220 of the first step 1, wherein the indicia 18 is exposed to alert persons of the steps and potential hazards, such as tripping or falling hazards. The horizontal surface 220 of the first step is carpet. The safety device 10 extends along a length of the first step 1. According to another example, as shown with respect to the second step 2, the safety device 10 is coupled to the horizontal surface 220 of the second step 2 similar to the safety device coupled to the first step 1. However, according to this example, the safety device does not extend the length of the second step 2 and is positioned intermediate ends of the second step 2. The horizontal surface 220 of the second step 2 is vinyl.
According to another example, as shown with respect to step 3, the safety device 10 is bent along the edge line 30 and coupled to the third step 3. The edge line 30 is aligned with the edge of the third step 3, wherein a first portion of the safety device 10 extends along the horizontal surface 220 of the third step and a second portion of the safety device 10 extends along a vertical surface 230. The indicia 18 is exposed to alert persons of the steps and hazards such as tripping or falling hazards. The horizontal surface 220 and the vertical surface 230 of the third step 3 is hardwood. The safety device 10 extends along a length of the third step 3. In yet another example, as shown with respect to the fourth step 4, the safety device 10 is coupled to the fourth step 4 similar to the safety device 10 coupled to the third step 3. However, in this example the safety device 10 does not extend the length of the fourth step 4 and is positioned intermediate ends of the fourth step 4. The horizontal surface 220 and the vertical surface 230 of the fourth step 4 is tile.
The structure 100 can also be a floor 300. The safety device 10 is removably adhered to the floor 300 by the second layer 16 and/or the attachment means 28, if present, wherein the indicia 18 is exposed to alert persons of the steps and/or hazards such as tripping or falling hazards. The floor 300 is concrete in the example. As mentioned hereinabove, the safety device 10 can be attached any type of surface as desired and not limited to carpet, vinyl, hardwood, tile, or concrete.
Advantageously, the safety device 10 can be used on any surface and can be reused and washed and still efficiently attach to the structure 100 such as a stairwell or floor or any other type of structure. Furthermore, the safety device can be removed and transferred to another structure or reattached to same structure after being washed due to the material used to form the second layer 16 maintaining its tackiness even after washing. Due to the material used to form the safety device 10, which is reusable and washable, the safety device 10 can be suitable for environments with sanitary requirements such as a hospital, school, and nursing home or any other environment with sanitary requirements. The safety device 10 is durable which results in minimal wear. The safety device 10 also efficiently conveys warnings to those with impaired depth perception.
From the foregoing description, one ordinarily skilled in the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, can make various changes and modifications to the invention to adapt it to various usages and conditions.
