Definitions

  • the invention relates to a hygiene-optimized door system for sanitary rooms and toilet cubicles, in particular for semi-public and public sanitary and toilet facilities.
  • a particularly critical area with regard to the risk of virus transmission through contaminated or virus-infected contact surfaces is semi-public or public sanitary and toilet facilities, since their use inevitably requires a large number of hand contacts, which are not up-to-date from a hygienic point of view and are also considered extremely by the users of these facilities uncomfortable but unavoidable.
  • a typical sanitary facility includes an anteroom with washbasins, which is entered through a door and from which you can reach the cabin space through a second door, from which the respective individual cabin, i.e. the actual purpose of use, is entered via another door.
  • a total of twelve hand contacts are required to operate the handles and two more hand contacts when using the cabin lock. This cumbersome sequence of movements and the large number of hand contacts are no longer hygienically acceptable.
  • the object of the invention is therefore to optimize semi-public and public toilet facilities and sanitary cubicles in particular from the point of view of hygiene and to enable their use with as little hand contact as possible and to simplify the sequence of movements during use.
  • the invention shows two alternative ways, one alternative being based on the use of a specially designed swing door and the other alternative being based on the use of an angled door.
  • the first variant defined in claims 1 to 6, which is also suitable in particular for a corona-compliant renovation of existing toilet facilities, is characterized in that the swing door is installed at an acute angle with respect to the longitudinal axis of the cabin in such a way that the functional gap opposite the opaque joint gap defines a line of sight directed into the adjoining interior wall of the cabin and preventing a view into the interior of the cabin.
  • each of the two open vertical longitudinal gaps is specifically modified in such a way that it is no longer possible to look into the cabin and the view from the inside to the outside is also blocked, which promotes the emotional security of the respective user.
  • the opaqueness of swing doors made possible by the invention makes the swing door ideal for use in toilet cubicles, which in particular achieves the advantages that the movement sequence when entering or leaving a toilet cubicle is significantly easier that the swing door can optionally be opened with the shoulder, the upper arm, the hip or the foot, i.e. without hand contact, and that a large operating element of a bolt can be provided for locking the cabin, which can optionally be operated with the wrist or the forearm, the in turn means contact-free, can be operated.
  • the second variant of the solution according to the invention uses a two-wing angled door with a wing made of a material that is preferably transparent over the entire surface and a wing made of opaque material, with the transparent wing closing the sanitary room when it is not in use and the opaque wing being opened by pivoting the transparent wing when entering the sanitary room the closed position corresponding to the occupied state is transferred and operating elements for moving the angled door are provided on the inner surfaces of both wings facing one another.
  • control elements in the form of vertically running push elements provides a vertical latch which, depending on the selected length, can be the shoulder, hip or foot can be operated comfortably and easily, thus making it possible to avoid any hand contact.
  • activation by a rollator or the footrest of a rollator if an accessible cabin is provided.
  • the locking element is automatically locked and the cabin door is closed, and releasing the lock again only requires a simple push actuation of the vertical latch, which is necessary in any case to leave the cabin.
  • FIG. 1 shows two toilet cubicles 11 arranged in mirror image, which are provided with swing doors 12 designed and arranged according to the invention.
  • the swing doors 12 are attached to frame parts 16 on the articulated side by means of conventional swing door fittings 15 .
  • the free vertical narrow side of the respective door lies opposite the associated frame part 17 and together with this forms a functional gap.
  • the longitudinal axis of the cabin running in the direction of the depth of the cabin is identified by 13 .
  • the swing door plane does not run perpendicularly to the longitudinal direction 13 of the cabin, contrary to the usual installation, but at an acute angle, which is preferably in the range of ⁇ 15 degrees.
  • the frame parts 16, 17 adjoining or interacting with the swinging door 12 are arranged obliquely, ie running at the angle mentioned to the longitudinal axis of the cabin, resulting in a sloping front for each cabin.
  • a continuous hinge band serving as a cover 22 can at the same time be designed in such a way that it limits the movement of the swinging door in both opening directions and thus prevents the swinging hinges from being swung over.
  • each swing door 12 relative to the longitudinal axis 13 of the cabin means that a function gap, for example about 3 mm wide, is formed between the swing door 12 and the associated frame part 13 .
  • This functional gap leads to the formation of a line of sight 21 which is directed towards the adjacent side wall 20, ie at most a short part of the front cabin wall 20 is visible, whereas it is not possible to see into the depths of the cabin when the door is closed.
  • the view from the inside to the outside i.e. parallel to the longitudinal axis 13 of the cabin, is also blocked by the inclined position or 15-degree position of the swing door 12 when closed, which promotes the emotional security of the user.
  • This function can be optimized by increasing the 15-degree angle and increasing the wall thickness of the door leaf and door frame, or by partially reinforcing only the functional gap.
  • the required opacity of the cabin is thus guaranteed without any impairment of the function of the swing door 12.
  • the partial perspective view 3 once again illustrates the principle according to the invention of realizing the opaqueness of the cabin on the functional gap side without the use of any additional components that impair the functionality of the swing door 12.
  • the locking unit 14 provided between the swinging door 2 and the frame part 17 can be designed as a simple slide bolt which can be actuated easily with the back of the hand or the fist or the forearm without making contact with the palm of the hand.
  • the information as to whether the car is "occupied” or “free” is - as usual - signaled with a display field in the locking unit in red or green, clearly visible to every waiting user.
  • the emergency opening is in the red field through a vertical "penny slot". This means that the bolt can be pushed back from the outside in an emergency and the swing door is free.
  • the pivoting angles of the swinging doors 12 of adjacent cubicles are limited either by a hinge or by fixed stops such that the doors always remain at a distance when both cubicles are vacated at the same time.
  • the sloping or 15-degree position of the swing doors reduces the maximum open door position in front of the cabin front by around 30%. In practice it is This aspect is even more advantageous because the swing door does not have to be opened all the way to exit the cabin.
  • the door designed according to the invention can optionally consist partially of frosted glass.
  • Frosted glass elements are not transparent, but allow the user to be seen from the outside in the vicinity of the door when they are about to unlock the door and leave the cabin. This represents a further advantage for systems with high frequency.
  • the swing door is attached to the associated frame part by means of swing fittings 15 with pivot points lying outside the plane of the door, and the joint gap 18 is designed to be opaque through the use of V-shaped profile parts 23, 24 that dip into one another without touching, which are attached to the front of the door 12 and are attached to the frame part 16.
  • the movement of the swinging door 12 is in no way influenced or impaired by this type of opaque closure of the joint gap, because the convex projection 23 and the concave recess 24 never come into contact with the two pivoting directions of the door 12, but ensure in the closed Position of the swing door 12 always the required opacity.
  • This solution is particularly - but by no means exclusively - suitable for swing doors with larger hinges and external pivot points, as shown in the illustration. So is the opacity too with a relatively wide hinge gap, for example 10 mm, can be achieved easily and without stress or wear.
  • a flat light module can also be placed on the cabins in such a way that the doors are illuminated on the outside and the cabin on the inside.
  • This module can be used to integrate the swing door stops outwards into this element and thus connect them to the cabin structure.
  • Movement-limiting stops for the swing doors are preferably provided on the wall side in the interior of the cabin and can also be designed as a hanging element for items of clothing.
  • the necessary external stops can also be provided on the front of the car and are indispensable in the case of two adjacent swing doors, since they must prevent the adjacent swing doors from colliding when they are opened at the same time.
  • FIG. 6 shows in a schematic representation the basic principle of a toilet facility comprising two sanitary rooms and equipped with angled doors, with both rooms being shown in the free, ie unused state.
  • angle doors 10 each consist of an opaque wing 8 (privacy wing) and a transparent wing 9 (transparency wing). On their insides, i. H. The sides of the angled door 10 facing one another are provided with actuating elements in the form of push elements, which will be explained in detail in connection with the associated locks.
  • the present invention makes it possible to increase the value and operability of the respective system optimize and to implement an automatic locking system that is automatically unlocked or opened by a simple push movement when leaving the sanitary room.
  • FIG. 7 shows a schematic partial representation of the use of vertical latches according to the invention, which can extend like a rod in different dimensions up to the entire height of the car door.
  • This vertical latch 1, 1' whose height, as mentioned, can be freely selected depending on the existing requirements, represents the logical solution for an operating option without hand contact.
  • the clear wing 9 does not require a locking mechanism.
  • This leaf only has to be fixed in the closed position with a standard door lock.
  • the latch is in the door lock as usual and engages in the striker plate on the frame.
  • the lock associated with the transparent wing has an emergency operating lever on the inside of the door, which can be designed as a simple, fold-out handle. This is used to allow the door to be closed and reopened from the inside when cleaning the inside of the transparent leaf. This also rules out the possibility that a person could be unintentionally locked behind the glass door.
  • Entering the cabin closed by the transparency wing 9 requires the user to actively move the transparency wing, who can then enter the cabin directly, in the course of which entering the room the opaque wing or privacy wing 8 opens the cabin behind the user closes and the lock of the privacy wing engages automatically. After closing the door, the closing element is thus automatically locked and the cabin door is locked, ie an additional lock is not required or omitted.
  • the latch or spring-loaded catch 6 is arranged in the door frame 7 and the mechanical locking element 2 is fastened to the impermeable wing 8 . Accordingly, there is a reciprocal design or mirrored arrangement of the elements, as they are otherwise provided in the conventional locking architecture.
  • the lock associated with the transparent wing 9 is of conventional design and accordingly the strike plate in the door frame has a cut-out for the case of this lock associated with the transparent wing 9, while in the area below the frame-side latch of the impermeable wing 8 associated lock is provided.
  • a recess is provided as a free space on the lock of the transparent wing so that the latch on the frame side does not interfere with the closing of the transparency wing 9.
  • the mechanical locking element 2 is designed in such a way that when the transparent wing moves due to a short push movement to enter the cabin and due to this movement the impermeable wing 8 comes to the closed position, the lock automatically engages because the pivoting locking element 4 is always in the closed position without operating the vertical latch. It is therefore not necessary to operate an additional locking unit.
  • a supporting locking mechanism can be provided for both directions of movement, which can also ensure a safe end position of both wings.
