Definitions

  • the invention initially relates to a fastening device for additional sanitary components on a contact surface, such as a wall, with a holding device and a device for generating a negative pressure, the holding device forming a base which has a valve and a contact surface-side vacuum chamber, and the device for generating the negative pressure is provided with a vacuum cylinder, which forms a sealing surface on the side facing the holding device, and in which a suction piston is guided with a sealing element facing the holding device, the vacuum cylinder forming a pull-out lock on the side facing away from the holding device.
  • Such a fastening device known from the prior art, which can be documented in printed form, is for example in FIG DE 20 2017 100 097 U1 disclosed. Since the vacuum is generated in several stages, holes in the vacuum cylinder that are close to the pull-out lock are passed over for the venting process so that the suction process can then be repeated.
  • the object of the invention is therefore to create an alternative solution which is ergonomically advantageous to handle and has a simple structure.
  • the solution according to the invention has the essential advantage that the suction piston is locked in its maximum starting position on the vacuum cylinder and can be released from the holding device by means of a large lever arm and reduced expenditure of force.
  • the valve is closed suddenly and the vacuum chamber is sealed by it.
  • the pull-out lock it is also possible for the pull-out lock to form four recesses for receiving one rib each.
  • the suction piston forms a sealing element with two annular recesses facing the holding device, a piston sealing ring being arranged in each of the two annular recesses of the sealing element and serving to hermetically seal the suction piston against the vacuum cylinder.
  • an ergonomic piston handle is arranged on the end of the suction piston.
  • the advantage of this method according to the invention consists in particular in the simplified handling and the reduction of the force required by means of a large lever arm when removing the device for generating the negative pressure from the holding device in order to trigger the venting process of the vacuum cylinder and then to repeat the suction process.
  • the fastening device is designated as a whole by the reference number 10.
  • the Fig. 1 shows the fastening device 10 according to the invention for additional sanitary components.
  • the fastening device 10 has a holding device 11 and a device for generating a negative pressure 12.
  • the holding device 11 consists of a circular section 13 and an L-shaped section 14, this end having a rectangular fastening opening 15 which is provided with a guide groove 16.
  • the fastening opening 15 serves to receive a functional component B, which is designed here as a hook part 17 and is provided with an extension piece 18 which has a guide rib 19.
  • the guide rib 19 interacts positively with the guide groove 16.
  • the hook part 17 is then fastened to the holding device 11 by means of a screw 20.
  • the hook part 17 is used, for example, to hang towels, bathrobes or clothes hooks. It is also conceivable here that the functional component B is designed as a ring-shaped towel holder, toilet roll holder, toothbrush cup holder or as a sanitary shelf for hygiene articles such as shampoos or shower gels. However, other forms and possible uses are also conceivable.
  • the holding device 11 On the side facing the contact surface W, the holding device 11 forms a cavity which has the function of a vacuum chamber K and into which a sealing ring 22 is inserted in order to seal the vacuum chamber K from the contact surface W.
  • the circular section 13 From the side facing away from the contact surface W, the circular section 13 forms a projection S which is provided with a central bore 21 which is in communication with the vacuum chamber K.
  • a one-piece valve 23 which consists of a ball seal 24 and a pin 25, which are fixed by a conical spring 26 and an elastic disc 27.
  • the valve 23 suddenly seals the vacuum chamber K as soon as the device for generating a vacuum 12 is detached from the holding device 11.
  • a multi-stage, elastic sealing ring 28 is arranged on the circular section 13. This consists of a disk E and a dome-like extension D, which forms two spaced-apart sealing rings R and is used for the sealing arrangement of the device for generating the negative pressure 12.
  • the elastic sealing ring 28 is arranged on the projection S when it is abutted on the circular portion 13. 21.
  • the device for generating the negative pressure 12 consists of a negative pressure cylinder 29 and a suction piston 30.
  • the vacuum cylinder 29 On the side facing the holding device 11, the vacuum cylinder 29 forms a sealing component A, which is provided with a sealing surface 33 and a sealing ring (not shown) resting on the inner circumferential surface.
  • the sealing surface is located 33 on the disk E of the sealing ring 28 and the sealing ring (not shown) of the vacuum cylinder 29 is jammed between the sealing rings R which are spaced apart.
  • the vacuum cylinder 29 On the side facing away from the holding device 11, the vacuum cylinder 29 has a pull-out lock 31, which forms part of the cylinder cross-section and has four recesses 32.
  • the suction piston 30 forms ribs 34 which are arranged at 90 ° in the longitudinal direction and which are positively guided in the recesses 32 of the lock 31.
  • the suction piston 30 also has a multi-stage sealing element 35 on the side facing the holding device 11, which forms three sealing disks C with spaced-apart recesses 36 arranged between them, which each serve to receive a piston sealing ring 37.
  • This multi-stage sealing element 35 serves to hermetically seal the suction piston 30 on the vacuum cylinder 29.
  • a free space F is formed, which in detail in the Figures 5b and 6b is shown and its function will be explained later.
  • the suction piston 30 On the side facing away from the holding device 11, the suction piston 30 forms a fastening extension 38 on which a piston handle 39 is arranged.
  • a cover cap 40 which, after the holding device 11 has been fastened to the contact surface W, serves to cover the elastic sealing ring 28 and the extension D in a visually attractive manner.
  • the Figures 2 to 6 show the pressing and suction process of the device for generating a negative pressure 12 on the holding device 11 for producing the negative pressure in the negative pressure chamber K.
  • FIG. 2 the holding device 11 with arranged hook part 17 and the device for generating a negative pressure 12 before it is deposited on the holding device 11, which is illustrated by the arrow direction P.
  • the suction piston 30 is in the minimum Pull-out position within the vacuum cylinder 29, the recesses 32 of the pull-out lock 31 of the vacuum cylinder 29 interacting with the ribs 34 of the suction piston 29.
  • the device for generating a negative pressure 12 is pressed against the disk E of the sealing ring 28 in the direction of arrow P by means of the sealing surface 33, the suction piston 30 still being in the minimum starting position.
  • FIG 5a shows the suction piston 30 in its maximum, unlocked pulled-out position.
  • the forced guidance of the ribs 34 in the recesses 32 is canceled and the free space F can be clearly seen ( Figure 5b ).
  • the vacuum is now completely generated in the vacuum cylinder 29 and the vacuum chamber K (not shown).
  • the suction piston 30 is shown in the maximum, locked, extended position.
  • the removal of the forced guidance of the ribs 34 in the recesses 32 enables the rotary displacement of the suction piston 30 by means of the piston handle 39 in the vacuum cylinder 29.
  • the Figure 6b shows the locking of the suction piston 30 in the vacuum cylinder 29.
  • the ribs 34 are clamped on the outside 41 of the vacuum cylinder 29, whereby the suction piston 30 is fixed on the vacuum cylinder 29 in the maximum extended position.
  • FIG. 7 the venting process of the fastening device 10 is shown.
  • the device for generating the negative pressure 12 is through a pivoting movement (see arrow direction P) is levered off the elastic sealing ring 28 of the holding device 11, whereby ambient air suddenly flows into the vacuum cylinder 29 and the vacuum in the vacuum cylinder 29 is canceled.
  • the valve 23 is closed abruptly at the same time and the vacuum chamber K is thus sealed. The suction process can now be repeated.
