Definitions

  • the invention relates to a device for a lavatory ring on a lavatory bowl, having a means for applying and displacing a protective cover on the lavatory ring, said lavatory ring having a horseshoe shape with the two end legs thereof being inserted through respective openings in a housing containing both a storage supply and a receiver for the protective cover, at least one of said end legs being attached in the housing.
  • the covering material or the protective cover is not formed as a finished stocking or hose.
  • the starting material is a web-formed cover material folded in the longitudinal direction and pulled out from a supply roll at one end of the seat. There the material is caused to envelop the body of the seat.
  • the seat has a slit for guiding the material, which is provided along the edges with a bead to be slid into the slit, and both ends of the seat are attached to and spaced apart from the lavatory bowl.
  • a receiving roll which takes up the used material while simultaneously drawing out new material from the supply roll.
  • the primary intent of devices of the aforementioned type is to safeguard personal hygiene as effectively as possible, particularly in connection with toilets outside the more protected milieu of private households.
  • Devices of the type forming the basis of the invention have been widely acclaimed in practice, and effective servicing systems have been developed to care for the devices and to ensure the execution of the tasks that would naturally be associated with their use, namely, the maintenance of the apparatus, supplying of protective covering, and cleaning of the apparatus and its surroundings.
  • the protective cover device is equipped with a knife, i.e, regardless of whether the protective cover is a plastic hose or stocking, or is formed from a blank that is folded together, it is common for the housing to be made capable of swinging upward, thus forming a hinge for the pivotal movement of the lavatory ring.
  • This type of upward swinging of the housing is undesirable for several reasons.
  • One reason is that a fixed mounting of the housing will provide a simpler and more convenient embodiment.
  • a second reason relates to the fact that in its upward swung state, the opening of the housing will be directed substantially vertically upward. This is undesirable for reasons of hygiene.
  • urine can easily hit the underside of the lavatory ring and the protective cover there and penetrate in through the opening in the housing. This will make the cleaning process more difficult.
  • the end legs of the lavatory ring be hinged outside the respective opening, for upward swinging from the lavatory bowl.
  • the housing should comprise a slide-snap mechanism for engagement with two attachment members connected with the lavatory bowl.
  • the attachment of the housing by means of such a slide-snap mechanism permits cleaning personnel to unfasten the housing and lift it up in a simple manner, thereby to gain access to the underside and back side of the housing.
  • the protective covering employed is a consumer article; and it is therefore also a purpose of the invention to propose measures that will conserve on the amount of protective covering used. It practice it has been shown that the mechanisms used to advance the protective covering are activated not only once, but often two or more times: for example, on completing his visit to the toilet, the user causes a new protective covering* to be advanced, whereafter a new user —just to be certain -- will activate the mechanism to bring out new protective covering; and it is also very common for a person to advance an excess of protective covering in order to be completely certain that the used portion disappears into the receiving unit.
  • the protective covering have markers, placed at intervals in the longitudinal direction thereof, to indicate the length of covering to be advanced. These marks will be observed by the user and will indicate sufficient advancement of protective covering, although this will not per se solve the problem of double activation.
  • the end legs of the lavatory ring may be hinged outside their respective openings by means of genuine hinges, i.e., hinge devices comprising hinge wings and hinge pins.
  • the hinges may also be formed, however, according to the invention, by sections of attenuated material in the end legs, when said end legs are constructed of a material conducive to this, for example, a suitable plastic material.
  • the lavatory ring is subjected to considerable load stress. It is therefore proposed, according to the invention, that the attached end leg comprise a metal element, formed of steel, for example, which serves as a hinge wing in the end leg hinge and is securely attached to the housing. As needed, there may advantageously be employed, in known manner, a knife member to cut up the protective cover at the receiving end thereof.
  • the protective cover passes off the lavatory ring and over into a receiver, where it is usually wound up onto a receiving spool.
  • means are provided at the protective cover receiving end to cause the protective cover to be spread out and laid flat on its transition into the receiver. This ensures an advantageous flattening of the protective cover prior to its being wound up, so that the volume available on the receiving spool need not be very much greater than the volume required by the storage roll, due to the expedience of winding up a flattened material.
  • the horseshoe shaped lavatory seat is preferably made of plastic and formed as a light, but strong element, which gives full performance under load (on use) because it rests upon the lavatory bowl.
  • the seat In unloaded state, however, the seat will be somewhat flexible — also in the plane of the seat —as a result of the light design and also as a result of the unilateral mounting.
  • the apparatus be provided with a safety catch for the free end leg, between the lavatory bowl and the lavatory ring.
  • the safety catch will provide the adjacent end leg of the seat with the necessary safeguarding against displacements.
  • the safety catch may have many different embodiments, but a simple and preferred design is one where the safety catch has the form of a ring member projecting out from the housing, adapted for engagement with a pin or stud on the underside of the free end leg. Another preferred embodiment involves the mounting within the housing of a pin or stud capable of passing clear through the free end leg.
  • the safety catch may be designed for safety engagement with the hinged end leg termination of the free end leg.
  • the housing may advantageously include a slide-snap mechanism for engagement with two attachment members connected to the lavatory bowl.
  • a device according to the invention which may also, as mentioned, have independent inventive merit, may advantageously include attachment members each having a locking groove on the underside thereof, to receive and engage with a T-head on a bolt fastened to the lavatory bowl, and having on the top side thereof a snap head eccentrically positioned relative to the locking groove.

  • Figure 8 shows a lavatory ring with a section of the housing removed, permitting a view of an attach ⁇ ment mechanism employed
  • Figure 9 shows a section as indicated by the section line in Fig. 8.
  • Figures 10 and 11 show an attachment member viewed from above and from the underside
  • Figure 12 shows a T-head for an attachment bolt
  • Figure 13 shows a section of a modified hinge embodiment
  • Figure 14 shows a flattening device according to the inven ⁇ tion.
  • a lavatory bowl 1 with a seat ring 2.
  • a housing 4 On lavatory bowl 1 at the rear edge thereof is mounted a housing 4.
  • the housing has two openings 5 and 6 into which the two end legs 7 and 8 of the horseshoe shaped lavatory ring 2 are inserted.
  • each end leg 7,8 is hinge-divided with the aid of respective hinges 9,10, allowing ring 2 to be swung up as shown in Fig. 4.
  • the outermost end sections of each end leg 7,8 are inserted from their respective hinge 9,10 through openings 5 and 6, respecti ⁇ vely, as shown in more detail in Fig. 3, where the upper half section 4' of the housing has been lifted up to show the inside of the housing.
  • One terminating end section 7' rests within housing 4, while the other terminating end section 8' is securely fastened inside the housing and is formed, in the transitional area for attachment flange 11, as a knife 12 for cutting the protective cover, not shown.
  • the protective cover emerges from a storage roll, not shown, in the left-hand half of housing 4 in Fig. 3, is fed onto the ring's terminating end section 7' , over hinge 9 and further along leg 7 and around the ring to leg 8, over hinge 10 and the terminating end section 8', where the stocking formed protective cover is split with the aid of knife 12 and passes over onto a receiving roll, not shown, situated in the right-hand chamber of housing 4 in Fig. 3.
  • hinges 9 and 10 will form break points where urine spill on the underside of ring 2 will run off and preferably down into lavatory bowl 1. Urine spill is thus prevented from penetrat ⁇ ing in through openings 5,6. These openings would be substan ⁇ tially vertical, in conformity with the upraised ring position in Fig. 4, if the housing were hinged to the lavatory bowl and thus functioned as a swing-up hinge device for the lavatory ring.
  • the horseshoe shaped lavatory seat (the seat ring) is prefer ⁇ ably constructed of plastic and formed, as shown, as a light, but strong member, which will perform to full effect under load (when used) because it then rests on the lavatory bowl.
  • seat ring 2 In unloaded state, however, seat ring 2 will be somewhat flexible, also in the plane of the seat, as a result of the unilateral attachment at 11. Particularly when swung up or down the free seat ring end 7,7' will be somewhat loose and could have a tendency to slide out of the provided opening 5 in housing 4.
  • a safety catch 15 for the free end leg 7,7' is built in between the upper edge of the lavatory bowl and the free end leg 7,7' of the seat ring. The placement of safety catch 15 is shown in Fig. 5.
  • the safety catch 15 is formed and situated so as to provide the seat's end leg 7 with lateral support when loaded, to ensure that the end leg does not undergo displacement in its longitudinal direction, to secure the terminating hinged end section 7' (hinge flap) projecting in through opening 5 in housing 4, and also to contribute toward lifting seat slightly when not loaded, so that the seat or lavatory ring will "float" above lavatory bowl 1.
  • the safety catch 15 is formed as a ring or loop, which engages with a locking pin or stud 16 on th underside of end leg termination 7'.
  • Locking pin 16 is shaped in such a way as to avoid creating any significant resistance for the advancement of the protective cover when the seat ring is in unloaded state.
  • the size of opening 5 in housing 4, i.e., the height of the opening, is adapted so as to prevent the hinge flap or the terminating end section 7' from being able to swing up and clear locking pin 16. Such upward swinging and clearance can occur only when the top portion 4' of the housing is lifted up.
  • FIG. 6 A variant of the safety catch is shown in Fig. 6.
  • the pin or stud 38 is formed in housing 4. Stud 38 is rounded off so as to offer little resistance to the protective cover, and is designed to grip like a hook clear through an opening 37 in the end leg.
  • the seat ring is preferably made of plastic, and this enables the hinges to be formed, as shown in Fig. 2, as attenuated sections as indicated by areas ',10' in Fig. 2.
  • the end leg termination 8' has on the underside thereof a small locking pin or stud 19 adapted to snap into a corresponding hole 20 in member 17, so that end leg termination 8' is held securely in place and hides the actual hinge wing 17, 18 which is construc ⁇ ted of, for example, steel.
  • Fig. 7 the device according to the invention is shown with the appurtenant protective cover 21.
  • This protective cover is provided at uniform intervals in the longitudinal direction thereof with length markers, here in the form of small, printed hearts 22,23. These markers serve as length indications that tell the user that a sufficient length of new and unused protective covering has been advanced over the seat ring 2.
  • the protective cover is rolled forward or advanced by means of appropriate mechanisms, so that the small marker heart 22 advances to the place where marker heart 23 is situated in Fig. 7. A new marker heart will then appear where marker heart 22 is situated in Fig. 7.
  • Figs. 8-12 are shown details associated with a slide-snap mechanism that may be used to advantage for securing housing 4 to the lavatory bowl 1.
  • Such an attachment mechanism is favorable for several reasons. First, it permits easy attachment and dismounting of the housing.
  • the mechanism is such that it may be adapted without further modification to possible spacing differences between the two attachment bolts generally used to fasten a seat, or in this case, a housing to the lavatory bowl.
  • the slide-snap mechanism shown comprises a slide member 24 displaceably disposed in housing 4, one end of said slide plate being actuated by a spring 25, which works against an end wall of housing 4, while the other end of said slide plate projects out to form an operating lever 26.
  • the slide plate has two openings 27, 28 (see Fig. 9). These openings 27, 28 are designed to freely receive a respective locking or snap head 29, 30 formed on the upper side of a respective attachment member 31 (Figs. 9, 10 and 11). As shown in Fig. 9, a locking connection will be established when slide plate 24 is slid to the right in Fig. 8 under the influence of spring 25. This locking effect may be reversed by exerting a pressure on the slide plate's operating lever 26, thereby moving plate 24 toward the left in Fig. 8 and in Fig. 9, so that head 29 is thereby brought into full alignment with the adjacent opening 27 and may pass freely therethrough.
  • the attachment members are in the form of respective round discs, as shown in Figs. 10 and 11; see also Fig. 9.
  • Attach ⁇ ment member 31 is provided on the underside thereof (Fig. 11) with an undercut locking groove 32, and on the top side thereof the attachment member has the previously mentioned locking head 29.
  • the undercut locking groove 32 is designed for engagement with a T-head 33 formed on a bolt 34 that replaces the conventional attachment bolt found on lavatory bowls, for attachment of the seat ring.
  • the eccentric positioning of the locking head or snap head 29 relative to locking groove 32 permits an adjustment to all relevant bolt spacings, i.e., the distance between the attachment bolts 34, with self-locking effect.
  • attachment members 31 are put in position on the respective T- heads 33 and said attachment members are twisted such that snap heads 29 attain the correct spacing, i.e., a spacing corre ⁇ sponding to the distance between holes 27 and 28 in slide plate
  • Fig. 13 there is shown a modified embodiment of the attachment area for seat ring 2.
  • End leg termination 8" is here constructed of plastic, as an integral part of housing 4, and covers metal insert 17', which has the same function as metal member 17 in Fig. 5.
  • end leg termination 8" is in reality a part of housing 4 and not a part of the actual seat ring 2, but in other respects the hinging, etc., functions in the same manner as described above.
  • end leg termination 8" has a widened area 35 in the plane of the seat ring.
  • This widened area 35 serves as a wing projection serving to spread out and flatten the protective cover (not shown) at the transition to the receiver, here envisaged as a receiving spool in the right- hand chamber of the housing shown in Fig. 13.
  • a knife 36 is indicated in Fig. 13, for cutting up the hose-like protective cover.
  • This knife 36 is in the form of a separate knife member built into the plastic material in termination 8", but it may also be a part of the reinforcement/hinge wing member 17' that is either underlying or embedded in the plastic. It may be particularly advantageous to have, as shown in the section in Fig. 14, a press member 39 within the housing to press down on the protective cover, so that it is flattened prior to spooling, thereby preventing the cover from wrapping onto receiving spool 40 in * multiple layers.
  • the press member is in the form of a plate and projects down, as shown, from the upper part of housing 4 to press against protective cover 41 where the latter passes off end leg 8'.
