DETAILED DESCRIPTION OF THE INVENTION

(7) 1: Device Against Drowning in Bathroom TubsManual Version

(8) FIG. 1 is a schematic diagram of a bath plug device according to a preferred embodiment of the present invention. According to FIG. 1, a cone 20 is used attached to the top of the bath plug 10, at least one pedal-like unit 30 (preferably two units as shown in FIG. 1) to the left and/or to the right of the cone 20 are attached, covering more or less the whole span of the bath tub. The user is supposed to have his feet not on the side of the cone, but closer to his own body, preferably by lifting his knees slightly.

(9) Once the user becomes unconscious, the body moves down along the bath tub, the feet pushing against the pedals 30 or the cone 20 itself. This moves the cone 20 away from the user and lifts the bath plug 10, allowing the water to flow out. In one embodiment, the bath plug device has an overall density which is slightly below the density of water (e.g. by choice of material of the bath plug formed cavities in the plug that contain air) such that the bath plug device starts to float as soon it is detached from the pipe. Thus, the bath plug 10 will not return to a pipe closing state once it is detached such that drain off of the bath tub water is not disturbed.

(10) With the lowering of the water level, the chance of survival increases dramatically. It is then only a matter of the speed of the water flowing out and the time needed for the bath tub to drain. This can be calculated by the diameter of the pipe and the water level.

(11) 2: Bathroom Tub DrowningElectric Version

(12) In an electric version, the cone 20 is placed on top of the draining pipe. However, the bath plug 10 resides in the cone 20, forming an assembly 31, the assembly 31 being connected with a fixed wire 40 to either an electric motor 50 or a compressed air tube 70 and a tilt sensor 60, e.g. a girometer fixed inside the assembly 31, which in turn are wirelessly connected to a bath security switch and/or a house server providing safety services like software that may trigger an alert at official services (a call center, police, ambulance, fire department etc.). On the side of the cone 20, between the plug 10 and the motor or tube, the cone 20 has an opening. In the fully retracted mode, the plug is above the opening.

(13) Once the bathroom switch is pressed, this information is transmitted to the assembly 31, causing the electric motor 50 or compressed air tube 70 to lift the plug over the opening. This causes water to enter the cone 20 and flow through the now-open drain pipe, thus lowering the water level.

(14) The pedals 30 described earlier can potentially be attached to the electric embodiment of the bath plug 10/cone 20 assembly 31, as well.

(15) If the cone 20 is pressed down, the embedded girometer can trigger the upward movement of the motor 50 or tube 70, and send a distress signal to the bathroom security switch and/or the house server such that further safety services are informed. E.g. a call center operator may first be allowed to communicate to the user in the bathroom and, if the user does not react, pictures or even a video signals may be transmitted to the operator. However, other safety means, like informing neighbors, residents of the home, or nearby relatives (first responders), may be triggered in addition or as an alternative. Such information may be provided via software on mobile phones of the respective first responders. Such measures (i.e. who should be informed in what case) may be selected by the user beforehand.

(16) 3: Shower Fall Prevention

(17) FIG. 2 is a schematic diagram of a shower fall prevention device according to a first preferred embodiment of the present invention. FIG. 3 is a perspective view diagram of a shower fall prevention device according to the first preferred embodiment of the present invention. The present invention has been made to give ease of movement. Normally, the structure does not require contact with the skin.

(18) Hardware

(19) A rod 100, preferably made from iron or stainless steel, described is fixed to the ceiling near the center of the shower ceiling either by a strong rubber band (not shown) with very little leeway or preferablyfor user comfortby an extendable and retractable belt 110 is rolled up in a box 112 similar to a safety belt retraction unit. If the unit is attached to a bath room, it will be placed on the ceiling, vertically aligned to where the person usually stands while showering.

(20) To the left side of the rod 100, a handle 200 is attached. An solid part 300 is bent down from the handle 200, then backwards in a half circle, then up again, from there in a straight or slightly curved line (indicated in FIG. 3) to the right side, where it bends down again in a half circle. The solid part 300 is fixed to the rod 100 at or near the middle of the straight or slightly curved part.

(21) Said straight or slightly curved part is extendable and retractable, e.g. by a telescopic mechanism in the rod, as an example but not limited to a expansion plug telescopic rod or other suitable detent mechanisms. The solid part 300 is bent up again, then to the left to about one half of the full width of the unit. At that point a small, soft cushion 400 is placed; in a preferred version of the unit, this cushion 400 can be moved upwards and to the side and may be locked in a position by a suitable locking mechanism. The cushion 400 is provided to prevent injuries of face and head of a user slipping in the shower and falling forward towards the shower wall (not shown).

(22) For more comfort the rod 300 can have a full cushion (not shown) placed around the whole area, in particular where the armpits would fall. In an alternative version, shower walls can be covered with a delta-shaped cushion (not shown), in which the long side of the triangle is attached to the wall, the shortest side under the longer side of the cushion triangle.

(23) FIG. 4 is a schematic diagram of a shower fall prevention device according to a second preferred embodiment of the present invention. Basically, the embodiment of FIG. 4 corresponds to the embodiment shown in FIGS. 2 and 3. The difference between said embodiments is the manner in which the rod 100 of FIG. 4 is fixed. Rod 101 does not have a fixing to a flexible member like in FIGS. 2 and 3 (belt 112) but instead comprises one or more solid rods 100 fixed to fixing points somewhere in the shower. E.g. rod 100 may be fixed directly to a shower tub or to walls surrounding the shower. Number and stability of rods 100 are chosen such that the device provides enough stability to support a falling person. Care should be taken to not place the rods 100 such that the user is hindered at entering and leaving the shower.

(24) Method of Use

(25) The user enters the shower and moves his body through the opening in front of the fall prevention unit, so that the straight or slightly bent part is close to his back, running from shoulder to shoulder. He puts his left arm through the left part, his left armpit over the unit's left half circle; his left hand grabs the handle 200 on his left side. He then stretches his right arm over the right half circle. He moves the unit on the back below his shoulders and extends or retracts the unit to a comfortable width, then places the soft cushion 400 in front and near his head.

(26) Once the user has put on the solid part of the mechanism, he or she may move freely inside the shower, only obeying that the left and right curves stay below the shoulders.

(27) Functionality

(28) In the case of a fall, the body of the user moves downward and/or forward. The forward movement is stopped on the left side by the solid piece with the handle 200 and in the middle by the cushion 400 near the face; this cushion stabilizes the head in the case in the case of a severe fall. The person slides down, having the fall stopped when the armpit falls in the downward half circles.

(29) Then, the fall is stopped either by the rubber band (not shown) or by the lock of within the belt retraction unit 112.

(30) The cushion on the wall (described above; not shown) would in severe cases cushion the back of the head against the wall; by placing the second-longest side on top, the head can slide down over the cushion, not having to move over a top or bottom step, which might cause additional head injuries.

(31) Connection to a Home Security Unit

(32) In a preferred version of the invention, a switch with a wireless connection and battery is attached to the belt 110 or the retraction unit 112. Once the impact is transmitted to the rubber band or the retraction unit locks, the switch sends a signal to either the remote server directly or to the bathroom switch unit, which uses this signal as if the alarm has been triggered.

(33) The switch can also be integrated into the cushion 400 so that a strong push against the cushion triggers the alarm.
