Definitions
- the invention relates to a device for preventing closing or locking of mutually movable first and second parts, such as door and door frames, which can be locked or locked by means of a latch which engages in a receptacle and can be unlocked by means of a key.
- a key is required with which the bolt which is latched into a latch is adjusted, thereby releasing the door.
- the key is forgotten in the area that can be locked by the door and the door closes unintentionally, it can no longer be opened from the outside. Rather, an attempt must be made to open the door again with a replacement key to be obtained or by requesting an emergency service.
- BESTATIGUNGSKOPIE The present invention is based on the problem of developing a device of the type mentioned at the outset in such a way that it is ensured that the parts which are movable relative to one another can only be locked if a user directly uses the key required for locking.
- the problem is essentially solved by the fact that one of the parts starts with a locking device with a locking element that can be adjusted between the parts, that the locking element is in a first position when the first and second parts are closed, and releases movement of the movable part and at in an open position of the movable part is adjusted to a second position and prevents the movable part from closing and that when the key interacts with the locking device, the adjustable locking element can be reset from its second position to the first position.
- a locking device which enables the movable part to be opened, which for the sake of simplicity is referred to below as the door.
- the locking element of the locking device automatically lies between the door and the part receiving it, which is referred to below as the door frame, to such an extent that the door can no longer fall into the lock. This means that it is no longer possible to accidentally close the door. Rather, the locking element must be moved back in a controlled manner from its second position that keeps the door open to the first position that releases the door. This requires the key required for the door, which is used to move the locking element back from its second position to the first position.
- the locking element itself can be pivoted about a first axis that runs in a fixed manner in the locking device or its housing, and is articulated in a second axis with an articulated arrangement on which the key acts.
- the locking device is simultaneously moved from its second to its first position.
- the joint arrangement itself comprises in particular two lever or link elements, one (the first) of the lever or link elements being pivotable about a third axis running fixed in the locking device or its housing, the lever or link elements being articulated to one another in a common fourth axis and the further (second) lever or link element in turn is then articulated in the second axis to the locking element.
- This hinge arrangement enables the locking element, which can also be referred to as a locking bolt, to be pivoted securely, so that it can be pivoted from its first position in which the door is released to the second position in which the door is locked before being locked.
- the key itself preferably acts on the joint arrangement in the region of the fourth axis connecting the lever elements, so that no great forces have to be applied to ensure the desired pivoting.
- the lever or link elements can be pivoted into a position in the housing of the locking device due to gravity such that the locking element is in its second position. This ensures, when the door is open, that the locking element prevents the door from closing, with the result that The key must first be inserted into the locking device or the housing in order to pivot the lever or link elements and thus the locking element so that the door can be closed.
- the part from which the locking device does not originate is another element, which can be designed as a magnet. If the blocking element is then made of a suitable material that can be attracted by the magnet, then when a relative movement takes place between the magnet and the blocking element, the latter is pulled out of its first position. It is particularly provided that the magnet and the locking device or the housing extend from the door. The magnet preferably starts from the edge which extends perpendicular to the plane spanned by the door and projects beyond the frame.
- This external force acting on the locking element ensures that when the locking element is in the first position, the locking element can remain in this position. This means that the door can be locked from the outside without the key having to intervene in the locking device at this moment.
- the housing of the locking device has an opening which can be penetrated by the locking element and lever and which is aligned with the further element such as the magnet.
- FIGS. 1 and 2 show a detailed view of a locking device shown in FIGS. 1 and 2,
- FIG. 4 shows the locking device according to FIG. 3 in the locking position
- Fig. 5 shows the locking device according to Fig. 3 and 4 in the non-locking position.
- a device is explained with the aid of a door 12 which can be pivoted into a door frame 10, with which an undesired closing or locking of the door 12 is prevented.
- a locking device 14 is provided which, in the exemplary embodiment, is fastened to the door frame 10, specifically to the inner surface 16 thereof, which points toward the interior of an area, such as space, to be blocked off by the door 12.
- the locking device 14 has a housing 18 with a cover 20.
- a hinge arrangement which is referred to below as a tilt joint 22, is pivotably arranged.
- the tilting joint 22 consists of two links 24, 26, which can also be referred to as lever elements and which are connected in an articulated manner via an axis 28.
- One of the links - link 24 in the exemplary embodiment - can be pivoted about an axis 30 which is arranged in a fixed manner in the housing 18.
- the axes 28, 30 each run in an end region of the link 24 or lever mentioned.
- the other link 26 has at its free end region an axis 32, in which a locking bolt 34 or locking element is articulated, which, on the one hand, can be pivoted about an axis 36 which is stationary in the housing 18.
- the axis 36 extends below the pivot axis 32 running in the central region of the locking bolt 34 and in particular the latter also below the fixed axis 30 of the tilting joint 22 and the axis 28 which connects the links 24, 26 in an articulated manner and is adjustable within the housing 18 in the manner described below.
- the locking bolt 34 can be pivoted with its end region 38 remote from the fixed axis 36 in dependence on the position of the tilting joint 22 in such a way that the region 38 either prevents the door 12 from closing (FIG. 2) or else enables it to be closed (FIG. 1).
- the section 38 of the locking bolt 34 can be pivoted out of the housing 18 to such an extent that it extends between the door frame 10 and the projecting edge 40 of the door 12.
- the axis 28 which connects the links 24, 26 in an articulated manner runs below a straight line on which the fixed axis 30 of the tilting joint 22 and the axis 32 in which the spermatic gland 34 is connected to the tilting joint 22 lie is. If a force now acts on the locking bolt 34 from the outside, the locking bolt 34 cannot be pressed into the housing 14, since the tilt joint 24 or the links 24, 26 rest on an abutment 42 within the housing 18 in the region of the axis 28. However, in order to be able to pivot the locking bolt 34 into the housing 18, the tilt joint 22, i. H. whose axis 28 in the exemplary embodiment is moved upward, that is to say away from the abutment 42.
- a zero position must be overcome in principle for pivoting into the second position; otherwise the key would have to be in the slot 64 when the door 12 was closed.
- a force acts on the locking bolt 38 when the door 12 is opened, which force is caused in the exemplary embodiment by a magnet 46.
- the magnet 46 or an element having the same effect extends from the peripheral edge 40 of the door 12 and is aligned with the locking bolt 38 or the opening of the housing 18 through which the locking bolt 38 passes. If the locking bar 34 is made of a material that can be attracted by the magnet 46, then when the magnet 46 is moved away from the door frame 10, the locking bar 38 is automatically pulled outward so that it moves into its position locking the door 12 (FIG 4) arrives. If necessary, the axes 28, 30, 32, 36 can be aligned with the movement of the magnet 46 in such a way that the desired smooth movement of the pivoting of the locking bolt 38 is ensured. Detached from this, the axes 28, 30, 32, 36 should run parallel to one another and perpendicular or approximately perpendicular to the plane spanned by the frame 10.
