Definitions

  • the present invention relates to an arrangement for handling and temporarily storing waste in a flexible tube or hose, comprising hose-closure devices which when closed squeeze the hose sealingly together so that the hose part that is located beneath the closure devices will form a sealed container, downfeed devices which function to feed the hose successively past the closure devices, and means for operating the downfeed means and the closure means, wherein the operating means are constructed to prevent activation of the downfeed means unless the closure means are located in or simulta ⁇ neously moved to an open position.
  • the invention is primarily intended for use with dry toilets although it can, of course, be used in conjunction with other apparatus in which waste or the like is deposited intermittently in a hose or tube.
  • the operating means includes a manoeuvering shaft which is common to both the closure devices and the downfeed means.
  • the manoeuvering shaft is reciprocatingly pivotable between a starting position, an intermediate position and a final position, wherein the downfeed means are arranged to be activated solely by rotation of the manoeuvering shaft in one direc- tion.
  • the mechanism which manoeuvers the closure devices is designed so that movement of the closure devices between their respective closed and open states is achieved by rotating the manoeuvering shaft between said starting position and said intermediate position, and the shaft is arranged to be rotated to the starting position automatically in the absence of external loads or forces.
  • the hose downfeed means have the form of two pairs of downfeed wheels, wherein the two wheels of each wheel pair are mounted in the same plane with their peripheries adjacent one another and with a part of the hose held firmly in the nip between the wheels of each pair, and a pendulum arm is provided for rotating the manoeuvering shaft. In its closed state, the closure device is pressed against a counter-pressure surface or anvil surface.
  • Fig. 1 is a partially cut-away side view of a dry toilet which includes an embodiment of an inventive device
  • Fig. 2 is a horizontal sectional view of the toilet shown in Figure 1;
  • Figs. 3-5 are partially cut-away side views of a bottom part of the toilet shown in Figures 1 and 2, and show the inven- tive arrangement in a starting position, an intermediate position and a final position respectively, and also show a manoeuvering shaft forming part of the arrangement;
  • Figs. 6 and 7 are side views of one embodiment of a dry toilet and show respectively the toilet in a storage state and a use state;
  • Fig. 8 is a perspective view of the telescopically collaps ⁇ ible casing of the toilet shown in Figures 6 and 7;
  • Fig. 9 illustrates a toilet insert fitted in a casing according to Figure 8.
  • the dry toilet illustrated in Figures 1-5 includes a casing 1 which carries conventionally a toilet seat and seat cover
  • a funnel-shaped toilet insert 3 having a comparatively large upper opening and a lower smaller opening is fitted between the toilet seat and an inventive hose-closing and hose-feeding mechanism 4.
  • a hose 5 of flexible material e.g. flexible plastic material, extends over the edge of the upper insert opening and passes down through the bottom insert opening and the mechanism 4 and into a storage space (not shown). As shown in Figure 1, that part of the hose 5 which lies outwardly of the toilet insert 3 is folded to a bellows- like configuration.
  • the hose-feeding and hose-closing mechanism includes two pairs of downfeed wheels 6, 7 and 8, 9 which are mounted diametrically opposite one another and outwardly of an imaginary vertical downward extension of the edges of the bottom insert opening.
  • the wheels 6, 7 and 8, 9 of each wheel pair are located in the same vertical planes sequentially of one another, and the peripheries of the wheels of each wheel pair are at least almost in abutment with one another.
  • the mutually opposing wheels 6, 8 and 7, 9 of the two wheel pairs are mutually connected by a respective common shaft 10 and 11 respectively.
  • a gear wheel 12 is connected to the shaft 10 through the medium of an appropriate freewheel clutch, such that the gear wheel 12 is able to rotate freely in relation to the shaft 10 in an anti ⁇ clockwise direction as seen in the Figures.
  • the teeth of the gear wheel 12 mesh with teeth on an arcuate toothed link 14.
  • the link 14 is non-rotatably mounted on a manoeuvering shaft 15. As the manoeuvering shaft is rotated in an anti-clockwise direction (as seen in the Figures), the gear wheel 12 will turn the shaft 10 and therewith the wheels 6 and 8 in a clockwise direction, whereas clockwise rotation of the manoeuvering shaft will have no affect on the shaft 10.
  • the manoeuvering shaft 15 also functions to manoeuver a flap 16 through the medium of a link mechanism, between a closed position in which the right side-edge of the flap ( Figures 1 and 3) lies against a sealing strip 17, as shown in said Figures, and an open position in which the right side-edge is distanced from the bottom insert opening, as shown in Figures 4 and 5.
  • the free end of a pivotal arm 18, 19 is pivotally attached to each end of the flap side-edge. As will best be seen from Figures 1 and 4-5, the arm 18 is pivotal about a pivot point 20.
  • a pull spring 21 extends between a triangular link 22, one of which is fixedly mounted on the manoeuvering shaft 15, and a pin 23 which projects out from the arm 18 and which is located at a much shorter distance from the pivot pin 20 of the arm than from the end that is connected to the flap.
  • the arm 18 will swing from the position shown in Figure 1 to the position shown in Figure 4.
  • One end of a pressure arm 24 is pivotally connected to the triangular link 22 at the same point as the spring 21, while its opposite end-part is slidably supported by the pin 23 on the arm 18 through the medium of a slot 25 provided at the end of the pressure arm 24.
  • the triangular link 22 is biassed towards its position shown in Figure 1 by means of a spring 26.
  • the arm 19 opposite the arm 18 is actuated by a similar link mechanism as that described above with reference to the arm 18, and the arms 18 and 19 will therefore swing synchro ⁇ nously as the manoeuvering shaft 15 is rotated.
  • the manoeu ⁇ vering shaft 15 is rotated anti-clockwise by pressing down or tramping on a pedal arm 27 which is non-rotatably connect- ed to the manoeuvering shaft.
  • the hose-feeding and hose-closing mechanism 4 has the form of a module or unit which is attached to the toilet casing 1 with all component parts already fitted to the casing of the module, possibly with the exception of the pedal arm.
  • the hose 5 In the initial state, or starting state I of the toilet, the hose 5 is closed-off by virtue of a part of the hose being compressed or pinched between the left side-edge of the flap 16 and the sealing strip 17. Opposing side-parts of the hose 5 are held firmly in the nip between the downfeeding wheels 6, 7, see Figure 2 and Figures 8, 9 respectively. If it is desired to empty the toilet basin after using the toilet, i.e. to empty that part of the hose 5 which is located within the funnel-shaped insert 3, the pedal arm 27 is pushed down with the aid of a foot.
  • the extension of the flap is suitably so large in the direction of movement that the left side-edge (as seen in Figures 1 and Figures 3- 5) reaches a wall of the toilet casing 1 when the flap is in its open position.
  • the link 14 that actuates the gear wheel 12 is also rotated therewith causing the downfeed wheels to rotate so as to advance a small length of hose from the toilet basin.
  • Figure 5 shows the pedal arm moved to its final position III.
  • the pedal arm As the pedal arm is pushed down from the intermediate position II to the final position III, further rotation of the triangular links 22 and the toothed link 14 takes place.
  • This further rotation of the toothed link 14 causes a further portion of the hose 5 to be fed into the collecting space 28, while said further rotation of the triangular links causes the pressure link 24 to move further to the left, this movement being controlled by the pin 23 and the slot 25 and by an extension of the spring 21.
  • the flap 16 does not move when the pedal arm 27 is pressed down between the positions II and III.
  • the spring 21 When the pedal arm has reached the position II, the spring 21 has contracted to a relaxed state and the pressure arm 24 has moved relative to the pin 23 at the same time, so as to rest against the inner end of the slot 25 as shown in the Figures.
  • the spring 26 is solely responsible for movement of the pedal arm between the positions II and I. As the pedal arm moves, the pressure arm 24 is moved to the right and carries with it the pin 23, and therewith the arm 18, so as to move the flaps 16 from its open to its closed position.
  • the spring 26 is suitably biassed so that when the flap 16 is in its closed position, the flap will press against the strip 17 with a determined force.
  • the aforedescribed dry toilet has many advantages over earlier known toilets of a similar kind, particularly with regard to optimal use of the hose.
  • downfeed of the hose can be interrupted at any time without jeopardizing the hose-closing function, therewith enabling downfeed of the hose to be interrupted immediately the toilet basin is emptied.
  • the inventive toilet is that if an article should fasten between the closure flap 16 and the sealing strip 17 such as to prevent the flap from closing completely, neither the closure manoeuver nor the downfeed manoeuver will be blocked and all that happens is that the manoeuvering shaft and the manoeuvering mechanisms cannot return to their starting positions.
  • the arrangement is also operated manually. In combina ⁇ tion, the inventive toilet is therefore very reliable in operation.
  • FIGs 6-8 illustrate a second embodiment of a toilet casing l ' in accordance with the invention.
  • This casing comprises two telescopic parts 30, 31 which can be brought from a packaged state in which said parts are telescoped one into the other, as shown in Figure 7, to a position of use in which the parts are extended and fixed relative to one another, as shown in Figure 6.
  • the parts 30, 31 are fixed relative to one another in the use state of the toilet, with the aid of latch means 32 which are pivotally mounted to the casing part 30 and which swing automatically from a horizon ⁇ tal to a vertical position as the casing part 30 is lifted up from the casing part 31.
  • Figure 8 also illustrates a toilet insert 33-37 which is suitable for use in combination with the casing 1' and which is shown in a stow-away or storage state in Figure 8.
  • the insert of this embodiment is comprised of a wire ring 33, two U-shaped wire stirrups 34, 35 and two upstanding attachment plates 36, 37 which are attached to the casing part 31.
  • the legs 38, 39 and 40, 41 of respective U- shaped stirrups 34, 35 diverge slightly in relation to the base 42, 43 of respective U-shaped devices, said base having a V-shape with an obtuse angle between the legs of the V and also slopes outwards in relation to the plane of its associ ⁇ ated base 42, 43 at an angle , which is shown in Figure 9 for the leg 38.
  • the U-shaped devices 34, 35 are pivotally attached to the attachment plates 36, 37 so as to be able to swing between a storage position, shown in full lines in Figure 8, and in chain lines in Figure 9, and a use position shown in full lines in Figure 9.
  • the bases 42, 43 of the U-shaped devices rest on a false bottom 44 of the casing part 31.
  • the extremities of the legs 38-41 of the U-shaped devices are inclined to the remainder of the legs, so as to extend generally vertically in the use position and are received in downwardly facing sockets on the ring 33.
  • the distance between the upstanding ends of two mutually opposing legs 38, 40 and 39, 41 respec- tively is slightly less than the distance between the sockets on the ring 33 into which said ends shall be fitted, there ⁇ with making it necessary to bend the legs slightly upwards when fitting the legs onto the ring.
  • the closure device may have the form of a sealing strip instead of the flap 16, and the manoeuvering shaft 15 may be connected to the arcuate tooth link 14 such that the link will solely be actuated by rotation of the manoeuvering shaft between the positions II and III.
  • the spring 26 may also be replaced with a torsion spring which acts directly on the manoeuvering shaft. The invention is therefore restricted solely by the content of the following Claims.
