Shower belt drowning prevention device

Abstract

The present invention relates to a drowning prevention device for use in the shower employing an autonomous, gravity-based mechanism. In one example, the drowning prevention device comprises a harness comprising a belt and a lanyard. In a fall situation, the body weight of a user wearing the belt of the drowning prevention device directs the force to the lanyard which pulls an attached cable connected to the shower's valve arm, closing the valve arm and stopping water flow.

Claims

DETAILED DESCRIPTION OF THE INVENTION

(18) FIG. 1 shows an embodiment of the belt and lanyard element of the present invention. Shown in FIG. 1 is a belt (100) to be worn by the user. Belt (100) is designed to fit around the user. Belt (100) is connected to a lanyard (103) with a hoop (101) attached to a first end of the lanyard (103) by passing the belt through hoop (101) as shown in FIG. 1. The belt may be made of any material(s) recognizable by those skilled in the art as being of suitable strength and water durability for the intended use and environment, such as nylon, polypropylene, and the like.

(19) At the second end of lanyard (103), which second end is away from belt (100) and hoop (101), is attached a lanyard connection cable (104) with two ends. The first end of the lanyard connection cable (104) is attached to the second end of lanyard (103) and the second end of the lanyard connection cable (104) is connected to a nipple (105). The lanyard (103) further comprises one or more quick release clasps (102) to make connecting and disconnecting from the device easy for the user.

(20) The nipple (105) at the second end of the lanyard connection cable (104) connects the lanyard connection cable, lanyard, belt and, ultimately, the user, to a slide release rod (106) and slide release tube (110), as described in further detail below.

(21) Slide release tube (110) has two ends. It is open at the first end. The slide release tube (110) contains a slide release rod (106) which moves freely slidable within slide release tube (110) through the first end of the slide release tube. As shown in FIGS. 2D and 2E, the diameter of the slide release rod (106) is very close to the inside diameter of the slide release tube (110), such that the slide release rod (106) is freely slidable within the slide release tube (110), but the nipple (105) is held in place in the seat (106a) while the seat (106a) is within the slide release tube (110) due to the position of the inside wall of the slide release tube (110).

(22) The first end of slide release rod (106) has a cut out called a seat (106a), within which nipple (105) sits. As shown in FIG. 2B, the seat (106a) is cut to the same diameter as the nipple (105). The nipple (105) when resting in the seat (106a) is the same diameter (118) as the slide release rod (106).

(23) As shown in FIG. 2C, the slide release rod (106) may have a channel (119) running longitudinally from the seat (106a) to the end of the slide release rod (106) to allow the lanyard connecting cable (104) to sit within this channel and along the slide release rod (106) and not obstruct free movement of the slide release rod (106) within the slide release tube (110). When the slide release rod (106) is within the slide release tube (110), the nipple (105) is held in the seat (106a) of the slide release rod (106) by the inside of the slide release tube (110) as noted above. This design allows the slide release rod (106) to be pulled to the first open end of the slide release tube (110). When the seat (106a) is pulled out of the first end of the slide release tube (110), the nipple (105) is no longer held in the seat (106a) and disconnects from the slide release rod (106), as shown in FIG. 2E.

(24) A first end of an activation cable (107) runs through the cable housing (109) freely and attaches to the second end of the slide release rod (106) held in place by cable set screws (108).

(25) The cable housing (109) and activation cable (107) then pass through the cable guide (112). The cable housing (109) is contained within a channel in a cable guide (112) by a cover plate (113) that is removably attachable to the cable guide (112). This holds the housing firmly while allowing free movement of the activation cable (107) within. It will be appreciated that, in some embodiments, the cable guide (112) may be mounted on the surface closer to the side of the shower which the user enters.

(26) The cable housing (109) then attaches to the water valve cable perch (114) as shown in FIG. 4. The water valve cable perch (114) is attached to the water feed pipe of the shower and sits between the water supply and the shower head. The water valve cable perch (114) sits on the back of water valve (115). The second end of the activation cable (107) attaches to water valve control arm (116). A guide edge on the valve perch (114) may be used to make accurate positioning on the water valve (115).

(27) In the event of a fall by the user, the pulling force on the lanyard (103) by the belt (100) worn by the user slides the slide release rod (106) in the slide release tube (110) thereby pulling the activation cable (107) and closing the water valve arm (116) which closes water valve (115) and prevents water flow from the water supply to the shower head. Once passed through its movement, the first end of the rod (106) slides to the first open end of the slide release tube (110) and lanyard (103) connecting nipple (105) is released.

(28) FIG. 7 is a schematic diagram showing the present invention attached to a user in a shower setting. The belt (100) is worn around the waist of the user, the lanyard connection strap (103) is connected to the slide release rod as described above, which is inside slide release tube (110) which passes through the cable guide (112). The cable housing (109) is held firmly by cover plate (113) allowing the activation cable (107) free movement. Certain elements are not shown in FIG. 7, including the cover (113), and clasps (102), though they are described elsewhere. The cable housing (109) and activation cable (107) run up the wall to join the water valve cable perch (114) which is fixed to the back of water valve (115) which is connected to water feed pipe. The cable housing (109) sits in the perch (114) and the activation cable (107) attaches to the water valve control arm (116). In this configuration, the system is active.

(29) FIG. 8 shows a representation depicting the present invention after a fall by the user. The slide release rod (106) has gone through its movement. The water valve is in the closed position and the lanyard (103) has disconnected.

(30) It is an object of the present invention that it be easily installed by a qualified contractor or a person of some skill in installations of this sort.

(31) It will be appreciated that, in certain embodiments, the choice of cable guide used will relate to the shower stall type.

(32) In certain embodiments in which a fiberglass shower stall is be fitted, it will be appreciated that a cable guide may be preferred.

(33) In certain embodiments involving installation on older homes, it will be appreciated that a cable bar may be used.

(34) In certain embodiments, such as, for example, installation in a rental apartment or house where permanent installations may not be desirable or possible, it will be appreciated that one or more cable guides may be recommended.

(35) It will be appreciated that this invention may have applications in hotels, group homes, retirement homes and hospitals, among other institutions.

(36) The said device is reusable and it will be appreciated that it can be adjusted to suit any height.
