Definitions

  • the invention further relates to a door with an opening system.
  • the invention further relates to a trolley with at least one door.
  • Carts that are used, for example, at trade fairs, in canteen kitchens or the like for storing and transporting goods often have doors that are used to close off a corresponding storage space in the cart.
  • they have a locking mechanism that is accessible from the outside.
  • an interior opening device is also provided, so that in the event of the door being accidentally closed, a person trapped in the storage space of the car can open the locked door from the inside.
  • the security lock is opened from the outside by entering a PIN.
  • the disadvantage here is the complex operation, because the PIN has to be entered each time to open the door.
  • the construction shown is also complicated and expensive, in particular due to the power supply for the electromechanical actuating element.
  • An object of the present invention is therefore to specify an opening system, a door with an opening system and a trolley with a door, which have a simpler and cheaper construction and provide greater flexibility with regard to securing the doors.
  • the present invention achieves the above objects with a door having an opening system according to any one of claims 1-13, in particular wherein the door is openable about a vertical axis.
  • the present invention solves the above objects in a trolley with at least one door according to claim 14.
  • a passive self-locking is to be understood in particular as a resistance caused by friction and/or gravity against slipping or twisting of two bodies lying against one another.
  • Active self-locking means in particular a force or a resistance to slipping or twisting of two bodies lying against one another by means of one or more force-providing elements.
  • a force-providing element is to be understood, for example, as a mechanical pressure and/or tension element, for example one or more springs.
  • the opening system can be designed purely mechanically and therefore simply and inexpensively. Another advantage is the ease of use of the opening system, especially from inside a storage room of a trolley. Another advantage is that the self-locking of the locking device enables a simple or easy locking of a door or the like. Likewise, a closed door remains securely locked by means of the opening system due to the self-locking effect when forces act in the opening direction of the door from inside a storage room, for example due to objects sliding in the storage room.
  • a lock is arranged to lock the door, the lock being able to be brought into a first open position and into a second closed position, it being possible for the door to be opened in the first position by means of the locking device and in the second Position the door is closed, and the closed position of the lock can be bypassed by means of the unlocking device, so that the locking device can be brought into the open position by means of the unlocking device.
  • the advantage of this is that the door can be locked as a whole and access from the outside can be restricted to the inside.
  • the unlocking element is designed to be horizontally movable, preferably as a button. A particularly easy-to-use unlocking element is thus provided.
  • the unlocking element is designed to be active and/or passively luminous. This improves the findability and operability of the unlocking element in the dark.
  • the unlocking element can be arranged flush with a surface of the door. The advantage of this is that no additional space has to be provided for the push button inside the storage space of a trolley.
  • the locking device has a linkage with at least one closure element arranged to be vertically displaceable.
  • the at least one closure element has, on its one upper side, a particularly T-shaped Projection and / or a hook.
  • the unlocking device is designed to convert a horizontal movement into a vertical movement for actuating the locking device. This ensures in a simple manner that the locking device can be actuated by means of the unlocking element.
  • the unlocking device comprises an element which has a surface which rises along the horizontal direction and which can be brought into sliding contact with at least one corresponding surface of the locking device.
  • the locking device comprises a spring device for providing the predeterminable force.
  • the locking device comprises at least one receiving element for the actuating element, so that the actuating element interacts at least partially with the locking device in order to provide the closed position of the locking device.
  • the at least one receiving element comprises a beveled surface which corresponds to a beveled surface of the actuating element, the surfaces being arranged in relation to one another such that they support the self-locking of the locking device.
  • this supports the self-locking of the locking device, ie the effect of the self-locking is increased, but at the same time a simple opening by means of the unlocking device is ensured.
  • the beveled surfaces are arranged at an angle of between 10 degrees and 45 degrees with respect to the vertical, in particular between 15 degrees and 35 degrees, preferably between 20 degrees and 30 degrees.
  • this provides support for the self-locking of the locking device in a simple manner, and on the other hand, opening by means of the unlocking device is possible without too much effort.
  • the locking device has a blocking element which is designed with the linkage to block the movement of the linkage in a first direction and which is designed to be flexible, in particular resilient, in a second direction, in particular perpendicular to the first direction .
  • An element can thus be provided which, on the one hand, prevents unlocking with a lock from the outside, but at the same time can bypass the lock when the unlocking element is actuated, so that the door can be opened in the closed position despite the lock.
  • the unlocking device comprises a spring arrangement with at least one spring which is designed to mechanically bring the locking device to open the door into its first position by means of a definable force.
  • the spring arrangement has a plurality of springs with which a force can be provided in different directions, in particular in a vertical and a horizontal direction. This increases the flexibility in the arrangement and actuation of the unlocking device.
  • the spring arrangement has a latching mechanism.
  • the advantage of this is a defined and at the same time reliable actuation of the unlocking device.
  • the latching mechanism has a release element, in particular arranged with limited rotation, which can be brought into positive engagement with a push-up element arranged perpendicular to the axis of rotation of the release element, the push-up element being mechanically connected to the locking device for opening the door in its first position interacts.
  • a reliable latching of the push-up element is made possible.
  • the term “push-up element” is to be understood in the broadest sense and refers, in particular in the description, preferably in the claims, to any element that is arranged to be displaceable in at least one direction. In particular, the direction is not limited to the vertical direction.
  • the release element can be brought from a starting position into a deflected position and can be returned to its starting position by means of at least one of the springs. A reliable return of the release element is thus provided.
  • the release element can be brought into positive engagement with the push-up element in its starting position.
  • the push-up element is in its initial position in positive engagement with the release element, so that the movement of the push-up element in the initial position of the release element is restricted by the latter.
  • the push-up element is arranged to be displaceable between an initial position and a release position, the push-up element being able to be held in its initial position by means of the release element.
  • the push-up element can be brought manually from its release position into its starting position by a user.
  • the advantage of this is that there is no need for complex reset mechanisms after the opening system has been triggered.
  • figure 1 shows an opening system in the upper part of a door according to an embodiment of the present invention
  • figure 2 shows an opening system in the lower part of a door according to an embodiment of the present invention
  • figure 3 the opening system of the figures 1 and 2 in the area of the lock and the unlocking element looking outwards from the inside of the door
  • figure 4 the opening system of the figure 3 in the area of the lock and the unlocking element viewed at an angle from the outside.
  • the door 2 has an inside 2b and an outside 2a.
  • the door 2 includes it a locking device 3, which has a vertical locking element 8a in the door 2 of a linkage 8 in the form of a flat steel element.
  • the closure element 8a protrudes from the inside of the door 2 and is provided there with a T-shaped projection 9, which is designed to run in the horizontal direction A.
  • This serves to interact with a projection 13 running obliquely in the vertical direction on an edge, for example of a carriage, in order to be able to hold the door 2 in its closed position and thus be able to provide self-locking.
  • an actuating element 4 is arranged in the door 2 and is accessible from the outside, which interacts with the linkage 8 to actuate the closure element 8a.
  • the actuating element 4 is designed here in the form of a slide that can be displaced to a limited extent in the vertical direction. If the slide is pushed upwards, the closure element 8a is lifted and the projection 9 no longer engages in the projection 13, so that the door 2 can be opened.
  • the linkage 8 can be locked in its closed position by means of a lock 7 in the door 2 that is accessible from the outside, with the actuating element 4 also being able to be locked here.
  • an unlocking device 5 is arranged in the door 2, which has a pushbutton 6 as an unlocking element, which is accessible from the inside 2b of the door 2 and can be moved horizontally.
  • the push button 6 By pressing the push button 6, the lock 7 is bridged on the one hand and the closure element 8a is simultaneously raised on the other hand, so that the two projections 9, 13 no longer engage and the door 2 can be opened.
  • the push button 6 has a beveled surface 10 on the inside of the door, which interacts with a corresponding surface 11 of the locking device 3 .
  • a blocking element 15 is also connected directly or indirectly via the linkage 8 to the closure element 8a.
  • the blocking element 15 is designed as a spring plate and interacts with the lock 7 in such a way that the lock 7 in its closed position holds the blocking element 15 and ultimately also the closure element 8a in its closed position.
  • a closing element 7a of the lock 7 acts on the blocking element 15 in the vertical direction from above, which causes a vertical movement of the Blocking element 15 upwards and thus prevents the closure element 8a connected thereto.
  • the push button 6 can be arranged in a depression 18 on the inside 2b of the door 2 so that it is arranged flush with the inner surface of the door 2 .
  • the push button 6 In order to open the door 2 from the inside 2b of the door, the push button 6 is pressed.
  • the beveled surface 10 of the push button inside 2b of the door 2 first hits the locking element 15, which is resilient in the axial direction.
  • the locking element 15 is thereby axially displaced or pushed away, so that the locking element 15 is no longer moved upwards by the closing element 7a with regard to its vertical movement is blocked.
  • the push button 6 With its beveled surface 10, the push button 6 now engages in a corresponding surface 11 of the locking device 3, here in a sliding element 16 connected to the closure element 8a.
  • the axial movement of the push button 6 causes the surfaces 10, 11 to slide past one another, so that the axial Movement of the push button 6 leads to a vertical movement of the sliding element 16, which ultimately leads to a vertical movement of the closure element 8a and thus to a movement of the closure element 8a from its closed position to its open position or position.
  • the door 2 can then be opened.
  • the locking device 3 is designed to be self-locking.
  • a spring 12 is connected to the linkage 8 in such a way that it holds the locking element 8a in its closed position with a predetermined force: The linkage 8 is thus pressed downwards by the spring 12 .

  • FIG. 8 shows in detail the engagement of the closure element 8a with corresponding elements arranged on the frame opposite the door 2, for example on the storage space of a car to be closed off by the door.
  • the closure element 8a protrudes from the interior 2b of the door 2 and has a T-shaped hook or projection 9 .
  • a double projection 13 is arranged correspondingly, so that the base of the T-shaped hook 9 reaches through the two partial projections 13 and is held in a non-positive manner on the partial projections 13 by the legs arranged perpendicular thereto. This represents the closed setting or position of the door 2.
  • the two projections 13 have beveled surfaces 13a which correspond to correspondingly beveled surfaces 9a on the two legs.
  • the beveled surfaces 9a, 13a are oriented in such a way that when the respective surfaces 9a, 13a slide on or against one another, the closure element 8a is pressed into its closed position due to gravity and/or the spring 12. To open the closure element 8a, it is lifted and the surfaces 9a, 13a slide past one another until the highest point 17 in the vertical direction is reached, at which the closure element 8a is no longer in engagement with the double projection or the partial projections 13.
