- the working area 39 is essentially defined by a hook length between a free end of the hook 33 and a closed end of the hook 33, wherein the release takes place in one direction only. The latter would be the case if the diver 17 or the hip belt 40 in Fig. 8a would move so far to the right that the eyelet 34 would slide off the free end of the hook 33. In a movement of the hip belt 40 to the left, however, no transfer to the released state 38 would
- Fig. 8b shows the reverse case where the hook 33 at
- Hip belt 40 is fixed and the eyelet 34 at the
- Air supply line 19 wherein the same applies to Fig. 8a said.
- the hook 33 (FIG. 8 a) or the eyelet 34 (FIG. 8 b) can be displaced along the air duct 19 before the hook 33 (FIG. 8 a) or the hook 33 (FIG The eyelet 34 ( Figure 8b) is fixed to the air duct 19.
- FIGS. 8a and 8b where release takes place only in the case of a sufficiently large displacement in exactly one specific direction
- Air supply line 19 is attached to the support device or the hip belt 40.
- Sliding element can be formed as a rail 35 and the second displacement element as a profile body 36 or vice versa, wherein the profile body 36 can be pushed at both ends of the rail 35 on this.
- FIG. 8c shows a case in which the first
- Sliding element is designed as a profile body 36 and the second displacement element as a rail 35, but has the
- Rail 35 at one end to a stop 50, so that again results in a situation analogous to the embodiments of FIGS. 8a and 8b.
- the profile body 36 can be pushed onto the rail 35 due to its geometry complementary to the rail geometry to produce the connected state 37, but only at that - free - end of the rail 35, which is not provided with the stop 50.
- In the connected state 37 of the profile body 36 can then be moved along the entire course of the rail 35 without the connected state 37 is released. That the course of the rail 35 defines the work area 39.
- a solution of the profile body 36 of the rail 35 is therefore only by sufficiently large displacement in one direction
- Fig. 8d shows the reverse case, where the profile body 36 is fixed to the hip belt 40 and the rail 35 with stop 50 on the air supply line 19, wherein the same applies to the Fig. 8c said.
- the profile body 36 (FIG. 8 c) or the rail 35 (Fig. 8d) along the air duct 19 can be moved accordingly before the profile body 36 (Fig. 8c) or the rail 35 (Fig. 8d) is fixed to the air duct 19.
- Fig. 9a shows an example of a rail 35 and a
- the rail 35 has a negative profile in the form of a recess in the
- State 37 is the profile body 36 in engagement with the
- Rail 35 Due to the complementary geometries of the rail 35 and the profile body 36 of the profile body 36 can be moved in the connected state 37 only along the course of the rail 35, but not approximately perpendicular to the course of the rail 35.
- the rail 35 has two free ends here - Without stop 50 - on, so a transfer from the connected
- Fig. 9b shows a completely analogous embodiment, but in which the rail 35 has a positive profile with a substantially T-shaped cross-section and the profile body 36 has a negative profile with a substantially U-shaped cross-section with mutually facing ends of the legs of the U-shape , The profile body 36 can be pushed laterally on the rail 35 - at both free ends - to produce the connected state 37. Again, due to the complementary geometries of the rail 35 and the
- Profile body 36 of the profile body 36 in the connected state 37 are displaced only along the course of the rail 35, but not approximately perpendicular to the profile of the rail 35. A transfer from the connected state 37 in the released state 38 is possible by sufficiently large displacement of the profile body 36 along the rail 35 in two opposite directions.
- Air supply line 19 is not optimal in view of a rapid separation of the air supply line 19 from the port 44 in emergency situations, since the port 44 is sometimes not easily accessible to the diver 17. Furthermore, this can
- Arrangement of the terminal 44 sometimes cause that when forward swimming under water 22 via the air supply line 19 tensile forces are introduced, trying to turn the diver 17 from an optimal horizontal position to an upright position.
- Fig. 2 shows a schematic partially cutaway
- Embodiment of a diving device 1 according to the invention in which this problem does not occur, since the terminal 44 of the air supply line 19 is disposed in the region 10 of the interior end 7 on the housing 3. Accordingly, the air drawn in through the air supply line 19 must flow from the port 44, i. from the region 10 of the interior end 7, at least up to that region of the interior 4 can flow, which in the region 21 of the maximum height 18, preferably in the region 9 of the
- Interior start 6 is to be able to be compressed there. This is made possible by an air channel 20, the fluidic connection of the air supply line 19 and the
- Terminal 44 in the region 21 of the maximum height 18 and in the area 9 of the interior beginning 6 in the interior. 4
- the air passage 20 is such
- Channel limiting wall 31 is formed, which also also forms the terminal 44.
- the air duct 20 is only partially formed by the channel boundary wall 31, namely on the one hand by the housing 3 and on the other hand by the channel boundary wall 31.
- Housing wall also forms the connection 44.
- the channel boundary wall 31 forms a continuation of the housing wall and thus limits the interior space 4, ie, the air duct 20 is at least partially disposed outside of the interior 20 here.
- 4 shows a variant in which the air duct 20 is completely formed by the housing 3 or the housing wall. The same applies to the connection 44.
- the air duct 20 is indeed disposed within said cross-section of the housing 3, but outside of the inner space 4.
- the flexible part 11 comes not only to rest on the inner wall 13, but also on the channel boundary wall 31 when the flexible member 11 is pressed into the interior 4.
