The pressure reducer 2 is attached to the support plate 1 of the breathing apparatus and is connected to the cylinder valve 5 of the steel cylinder 6 via a high-pressure nozzle 3 and a connecting handwheel 4. The protective device? is attached to the Haschenhals8 by means of a stable screwable clamp 8 α . The protective device is designed in the form of a deflector bracket or a bumper rail 9, the end 10 of which merges into the bottle jacket 11 at the transition point 12 in an aligned manner. The other end 13 of the deflector bar or the bumper rail 9 protrudes beyond the height of the handwheel 14 of the flask valve S - as seen in the direction of its axis. The deflector bar or bumper rail 9 is provided with a stop surface 15 adapted to the bottle shoulder, so that as little space as possible remains at the transition from the bottle shoulder to the Abweisebügel9 or that the Abweisebügel9 rests against the bottle shoulder at this point or in the event of a shock - ^ Äbügel 9 can continue to be provided with a ver _ _{der adwcu * = e,} which can also have a ^strong " ⁿ 8 ^s " PPf _{17 trai} , _eB , with which the stop is n cne »β ^ bottle valve housing protection ^ ^ _{a still larger} e

ι 2 are attached and on both sides in arches to the claims: Flascheaventil or the pressure reducer are passed. The brackets are then at their top 1. Protective device for the bottle valve bent back to the support frame and with its end of pressurized gas cylinders for breathing apparatus, with 5 ends attached to this. The well-known Schutzbübei the protective device from a bottle gel protrudes relatively far laterally over the neck attached bumper or bumper bar advises out, so that the device wearer while working - exists that partially encompasses the cylinder valve, especially when putting down the device - characterized in that it frequently hits, even if this is not done to protect the protective device (7) with one of the curvature of the cylinder valve, the pressure reducer or the like Bottle shoulder adapted stop surface (IS) would be necessary. Since the protective bars and with one of the outer surfaces of the bottle must absorb moderately large bottle weight, tilgehäuses (5) adapted stop surface (17) they must be very stable and therefore heavy is provided. to be executed; this increases the weight of the 2.

To the neck of the bottle 3. Protection device according to claim 1 and 2, the one bottle is a bottle shut-off valve attached thereby characterized in that the outer surface stigt, which is also the bottle shut-off valve for the the protective device (7) is on the surface-side other compressed gas cylinder and with their cylinder gem End in alignment with the lateral surface (11) of the neck is connected via a pressure line. The bei-gas cylinder transforms. 35 the bottle necks are connected by a clamp 4. Protection device according to claim 1 to 3, the pressure connecting the two bottles thereby marked that the protective device gas line and the cylinder valve, but not device with a breakthrough (18) to form the handwheel protects (British patent a handle is provided. 1 103 235). 30 The invention is based on the object of a to train such protective device so that they Space-saving and lightweight and that it is still stable enough to work properly The invention relates to a protective device for granting protection. the cylinder valve of pressurized gas cylinders for breathing 35 The invention consists in that the protective devices, wherein the protection device from a direction with one of the curvature of the bottle shoulder bumper rail attached to the bottle neck or adapted stop surface for support against the consists of a bracket that partially connects the cylinder valve with the shoulder of the cylinder and with one of the outer surfaces of the encompasses. Bottle valve housing adapted stop surface There are support devices for two or more 40 to support against the cylinder valve housing. Pressurized gas cylinders for being carried on the back can be seen. Respiratory protection equipment known. The Tragvor- As a result of the training according to the invention is located direction with one in the gap between the protection device and the bottle shoulder the pressurized gas cylinders lying close to one another and the cylinder valve housing, is therefore neat, closed frame, on which 45 is supported several times and securely, so that it is space-saving the bottles and, if necessary, the fittings are designed to be fortifying, light and resistant are stigt. The outer boundary surface of the frame can. mens coincides with the levels that the coats The protective device according to the invention is touch the pressurized gas cylinders. The frame ratio is small and therefore only has one Men in the area of the cylinder valves further highlighted 50 low weight. The one from the guard pulled as this and preferably has the form of intercepted impacts are directly on the sta- of a spur. The spur-shaped part of the bile surface is transferred. The frame can be provided with a reinforcing piece. According to a further embodiment of the invention. The spur-shaped part or the device consists of a bumper rail or a reinforcement piece inserted in it can be used to fasten a deflector bar that partially overlaps the face of the hand latch of the bottle valves or for fastening the and with one of the stop bottle connections diei .en. This known supporting surface is provided with reinforcing ribs. The seal, which serves as a protective device, is only created for protection against impacts acting in the axial direction of devices with two or more pressurized gas cylinders on the cylinder valve,
reversible (German patent specification 1 027 517). 60 According to a further embodiment of the invention There are also support devices for the outer surface of the protective device Compressed air breathing apparatus known that only with a ren surface-side end in alignment in the jacket compressed gas cylinder are equipped. Thereby, the area of the pressurized gas cylinder is passed over. This will Riaschen valve of the pressurized gas cylinder of the pressure reduction a smooth, step-free outer surface of the Vorrer attached to which the device carrier reaches via a fall 65 direction. hose is connected. In these devices, the protective device according to the invention can it is known to continue the support frame with two protective bars with an opening to form one provided, which be provided on the side edges of the wire plate handle.
