Description

The present invention relates to a device for preventing the closing of a door according to the preamble of claim 1 and a system of such a device and a door.

A device for preventing the closing of a door is used, inter alia, the terminal protection. It is to be prevented that the door is closed when, for example, a child's hand is in a gap between the door and the door frame.

Devices for preventing the closing of a door are known from the prior art. DE 20 2006 017 037 U1 shows a device in which a blocking means is secured in a lock side upper corner of the door frame. The blocking means may assume a release position and a blocking position. In the release position closing of the door is possible, whereas in the blocking position closing of the door is prevented by the door abutting the blocking means.

In the device according to DE 20 2006 017 037 U1 When the door is opened, the blocking means is automatically moved to the blocking position.

A disadvantage is in particular that the device must be mounted in the upper corner of the door frame, so that it is difficult or impossible to reach for small people to operate the unlocking function. In addition, the device can only be used for either right-hand or left-hand doors according to the relevant DIN standard. This increases the production costs.

In contrast, the present invention has for its object to provide a device which can be attached at any height to a door on both the right and left side, and to provide a system with such a device.

This object is achieved by the devices according to claims 1, 5 and 6 and the system according to claim 14. Embodiments of the invention are indicated in the dependent claims.

The device comprises a blocking means and an actuating means. The blocking means is adapted to be attached to the door. This can be done directly or indirectly. For example, another component of the device may be attached to the door so that the blocking means is not directly but indirectly attached to the door. In this case, it is possible that a space is arranged between the door and the blocking means. In the attached state, the blocking means can be moved between a blocking position and a release position. The movement is triggered by an actuation of the actuating means. When the blocking means is attached to the door, it blocks the closing of the door in the blocking position. In the release position it is possible to close the door.
The fact that the blocking agent is attached to the door, the device can be mounted at any height. For example, it is possible to mount the device at a height so that a small adult person can reach the actuating means, whereas for a child this is not possible.

In the blocking position, the blocking means may be designed to abut against a door frame and / or on a component arranged on the door frame. It does not matter if the Main closing edge of the door frame is on the right or left. Thus, the device can be used for both variants.

The device should be designed in particular as a terminal protection. This may in particular mean that the device prevents a human hand, for example a child, from becoming trapped between the door and the door frame, which can lead to injuries. The device may differ from known devices in particular in that the blocking means is arranged on the door so that when slamming the door a sufficiently large gap between the door and the door frame remains so that a human hand is not injured when the blocking means in the blocking position is.

According to claim 1, the blocking means in the mounted state on the door, in particular in the blocking position, pivotable about a pivot axis. If the blocking means abuts against the door frame because it is in the blocking position and the door has been moved towards the door frame, the pivotability ensures that the blocking means is first slightly pivoted and then supported on the door. In this way, the forces that occur are forwarded to the door via the blocking means, without the door and / or the device being damaged.

Otherwise, these forces would be passed through the attachment point of the device to the door, whereby the attachment point would be heavily mechanically stressed and would break out of the door after some of these operations.

The pivoting is thus ensured that the device reliably even after several locking operations the door is attached and not overly mechanically stressed.

According to one embodiment of the invention, the pivot axis of the blocking means may extend parallel to a pivot axis of the door.

According to one embodiment of the invention, the device may comprise a first return means which applies a restoring torque to the blocking means. In this way, the device can be used again and again without intervention by a user in the manner according to the invention.

According to one embodiment of the invention, the restoring torque in the door-mounted state of the blocking means may counteract pivotal movement of the blocking means towards the door. Thus, if the blocking means abuts against the door frame, the blocking means is pivoted against the return torque. If no forces or only small forces act on the blocking agent, the blocking agent is pivoted by the restoring torque back to the starting position.

According to one embodiment of the invention, the first return means may be formed as a spring, in particular as a torsion spring.

According to one embodiment of the invention, a clearance between the blocking means and the door may be present in the door-mounted state of the blocking means. This clearance allows pivoting of the blocking means about the pivot axis when the blocking means abuts the door frame. In the pivoted state, the blocking agent through the door supported and forces are passed from the blocking agent directly to the door, whereby the attachment of the device is protected at the door.

According to claim 5, the device comprises a second return means, which is adapted to exert a restoring force on the blocking means when the blocking means is in the release position. The restoring force acting on the blocking means is directed in the direction of the blocking position.

The restoring force ensures that the blocking means is in the blocking position when no other force is exerted on the blocking means, for example triggered by an actuation of the actuating means. So as soon as the door is opened and the actuating means is not actuated, the blocking means is automatically moved to the blocking position. The protective function of the device is thus triggered automatically when opening the door.

When the door is closed, the blocking means may be held in the release position by the door frame or by a component disposed on the door frame.

According to one embodiment of the invention, the blocking means may be adapted to prevent the closing of the door by abutting in the blocking position on a door frame or on a component arranged on the door frame.

According to claim 6, the blocking means may comprise a projection. This projection is advantageous because it can prevent a child from inserting their fingers into the small gap between the door frame and door when the door is not opened wide enough for the blocking means to reach the blocking position. If the Thus, the door is only opened so far that the projection no longer touches the door frame, the blocking means is moved by the second return means slightly in the direction of the blocking position, so that even in this state, a jamming of the fingers is prevented.

According to one embodiment of the invention, the projection may extend in the direction of the door frame when the blocking means in the door-mounted state with the door closed in the release position.

According to one embodiment of the invention, the projection may be arranged in the attached to the door state on a door facing the end portion of the blocking means.

According to one embodiment of the invention, the device may comprise a translationally movable means, which is translationally movable by the actuating means and by the second return means. The blocking means may be attached to the movable means. The blocking means can thus be moved together with the movable means. The translationally movable means may be, for example, a slider or a linear slide.

According to one embodiment of the invention, the actuating means may be rotatable. Upon rotation of the actuating means, the movable means can be moved translationally. For this purpose, the device may for example comprise a coupling means, which converts the rotational movement of the actuating means in the translational movement of the movable means.

According to one embodiment of the invention, the actuating means may be guided in a slot eccentric exhibit. The eccentric is configured to convert a rotational movement of the actuating means into a linear movement of the movable means.

According to one embodiment of the invention, the device may comprise at least a first stop, which limits a rotational range of the actuating means in a first direction of rotation.

According to one embodiment of the invention, the device may comprise a second stop which limits the range of rotation of the actuating means in a second direction of rotation, which is opposite to the first direction of rotation.

It is also possible that the device has one or two stops for the movable means, which are designed to restrict the range of movement of the movable means.

By restricting the range of rotation, the translational movement of the movable means can be restricted so that it is not moved too far. If the blocking means protrudes too far, undesirably large lever forces can occur if the blocking means strikes the door frame or the component arranged on the door frame.

According to one embodiment of the invention, the device may comprise a first spacing means for attachment to the door. The first spacer means may be elastic or provided with a damper mechanism. By the elastic attachment or the damping mechanism forces can be cushioned or damped, which occur when the blocking means strikes the door frame or on the door frame arranged component.

According to one embodiment of the invention, the actuating means can be arranged on a first side of the door. The device may also comprise a further actuating means which can be arranged on a second side of the door opposite the first side. For example, the first side may be the hinge side, also called the opening side, while the second side is the opposite hinge side, also called the closing side. Thus, a movement of the blocking agent can be triggered from both sides.

According to one embodiment of the invention, the blocking means may comprise a lubricant, for example a roller, which is adapted to slide along a door frame when the door is opened. This is particularly advantageous to protect the door frame. When the door is closed, the restoring force presses the blocking means in the direction of the door frame. When the door is opened, the sliding of the lubricant prevents damage.

If a roller is used as the lubricant, it can roll along the door frame when the door is opened. As a result, damage is avoided.

According to one embodiment of the invention, the roller may be arranged on a leg which extends in a direction which is not parallel to the direction of movement of the movable means. In addition, the leg may be resilient or provided with a damping system. By this embodiment of the leg forces can be cushioned or damped, which occur when the blocking means strikes the door frame or on the door frame arranged component.

According to one embodiment of the invention, the device may comprise a second spacing means. The second spacing means may be arrangeable on the door frame such that the blocking means abuts the second spacing means in the blocking position when closing the door. By using the second spacer means, the gap between the door and the door frame can be increased, so that the risk of jamming is reduced.

According to one embodiment of the invention, the second spacing means may be at least partially elastic or provided with a damping element. For example, the second spacing means consist of two components, of which only one is elastic or provided with a damping element. As a result, forces can be cushioned or damped, which occur when the blocking means strikes the door frame or on the component arranged on the door frame.

According to one embodiment of the invention, the device may comprise a locking means. The blocking means can engage in the blocking position at the stop on the door frame or on the second spacer means on the locking means. The locking means may be formed, for example, as a mechanical trap. The latching means prevents unwanted springing back of the door after an abutment of the blocking means on the door frame or on the second spacer means
The system according to claim 14 comprises a door and a device according to an embodiment of the invention. The device is attached to the door.

According to one embodiment of the invention, the blocking means may be disposed on a mating hinge side of the door.

According to one embodiment of the invention, the door may have a recess. The device may be partially disposed in the recess. At least the blocking means projects out of the recess in the blocking position.

According to one embodiment of the invention, the system may comprise a door frame. On the door frame, a holding means may be arranged, which holds the blocking means with the door closed in the release position. This is particularly advantageous in flush closing doors.

The device 100 comprises an actuating means (in Figures 1A and 1B not shown) and a blocking means 102. By a rotation of the actuating means, the blocking means 102 between an in Figure 1A shown release position and a in FIG. 1B shown blocking position to be moved. In the blocking position, the distance between the blocking means 102 and the actuating means is greater than in the release position. In the blocking position, the blocking means 102 prevents the closing of a door by striking the door frame or a component arranged on the door frame. In the release position, the door is closed.

In addition, the device 100 comprises a guided in a slot 104 eccentric 103 which is connected to the actuating means. By this mechanism, the rotational movement of the actuating means in a translational movement of a translational movable By means of 105 implemented. On the movable means 105, the blocking means 102 is arranged. The rotational movement of the actuating means is limited by two stops 106.

The movable means 105 is connected to return means 107 which exert a restoring force on the blocking means 102 via the movable means 105 when the blocking means 102 is in the release position. The return means 107 may be, for example, gas springs. The restoring force is directed towards the blocking position, so that the blocking means 102 is automatically moved to the blocking position when the actuating means is not actuated and the door is opened. This mechanism ensures that the device reliably prevents the door from closing.

In FIG. 2 It is shown that the movable means 105 has a leg 200 on which the blocking means 102 is arranged. The leg 200 is resilient or provided with a damping system, so that forces are absorbed or damped, which occur when the blocking means 102 abuts against a door frame or on a door frame arranged component.

The blocking means 102 is designed as a roller which is designed to roll along the door frame when the door is opened. When the door is closed, the restoring force of the return means 107 presses the blocking means 102 against the door frame. The fact that the roller rolls on the door frame, damage to the door frame is prevented.

In the FIG. 3B The device 300 shown has an alternative blocking means with a stabilizing element 301 and a elastic or damping element 302 on. The elastic or damping element 302 is connected to the stabilizing element 301. The elastic element 302 absorbs or dampens forces when it strikes a door frame or a component arranged on the door frame.

At the in FIG. 3C In the illustrated device 303, the blocking means is designed as an elastic or damping element 304.

In FIG. 4 the actuating means 400 is shown, which is connected by a recess 402 of a cover 401 with the mechanism of the device, so that a rotation of the actuating means 400 is converted into a translational movement of the movable means 105.

The device 100 also includes a first spacer 403 having a recess 404 for attaching the device to a door. The first spacer means 403 may be formed elastically or provided with a damping element, so that occurring forces are cushioned or damped. Through the recess 404, the mechanism of the device 100 can be connected to a further actuating means on the other side of the door, so that an actuation of both sides of the door is possible.

It is also in FIG. 4 a bolt 405 is shown about which the leg 200 is pivotable. When a force acting on the leg 200 of this can give something and swing around the bolt 405.

In the Figures 6A and 6B It is shown that the device 100 can be actuated from both sides of the door 600 using the actuating means 400. The blocking means 102 is in the blocking position and strikes the door frame 601, thereby preventing the door 600 from being closed.

The FIGS. 7A and 7B differ from the representations in the Figures 6A and 6B in particular in that a second spacing means 700 is arranged on the door frame 601. When the blocking means 102 is in the blocking position, it hits the second spacing means 700. As a result, the door frame 601 is spared. In addition, the gap between the door 600 and the door frame 601 is increased, so that the risk of jamming is reduced.

In Figure 8A the device is out of the FIGS. 7A and 7B shown in a sectional view from above. In FIG. 8B At the second spacing means 700, an elastic or damping element 800 is arranged such that the blocking means 102 abuts against the elastic or damping element 800, which cushions occurring forces.

In FIG. 8C The device 100 has a locking means 801 arranged on the frame 601. When the blocking means 102 is in the blocking position and the door is closed, the blocking means 102 engages in the locking means 801, so that a spring-back of the door due to the stop of the blocking means 102 is prevented.

In FIG. 9 a door 900 is shown which is flush with the door frame 901. In such a door, the apparatus 100 may include a retaining means 902 which holds the blocking means 102 in the release position when the door 900 is closed. Thereby Opening the door 900 is facilitated because the actuating means 400 need not be actuated to move the blocking means 102 to the release position.

In the FIGS. 10 to 13 a further embodiment of the invention is shown. The device 1000 comprises a blocking means 1001 and two return means 107. A projection 1002 is arranged on the blocking means 1001. The blocking means 1001 can be moved in a translatory manner similar to the devices 100 and 300 described above and is intended as a clamp protection to prevent the closing of a door.

The projection 1002 is disposed on a door-facing end portion of the blocking means 1001 and extends toward the door frame when the blocking means 1001 is in the release position and the door is closed. The protrusion 1002 is slightly narrower than the remaining area of the blocking means 1001. Therefore, the protrusion 1002 can be used to already prevent the door from closing when the door is opened only a relatively small gap.

In Figure 11A the device 1000 is shown in the release position. If the device 1000 is mounted in this position on a door, the door can be easily opened and closed. FIG. 11B shows the same device 1000 in the blocking position, so that the closing of the door is prevented because the blocking means 1001 abuts the door frame when the door moves towards the door frame. FIG. 11C differs from FIG. 11B in that the blocking means 1001 has been pivoted about a pivot axis 1200, which will be explained in more detail below. The arrangement of the blocking means 1001 from FIG. 11B corresponds to the arrangement of the FIGS. 12A and 13A , The order of the blocking agent FIG. 11C corresponds to the arrangement of the Figures 12B and 13B ,

In the FIGS. 12A and 12B the pivot axis 1200 of the device 1000 is shown, about which the blocking means 1001 is pivotable. When mounted on the door state, the pivot axis 1200 is parallel to the pivot axis of the door. The blocking means 1001 is pivotable in a direction in which the door is in the door mounted state. Therefore, the blocking means 1001 is pivoted in the direction of the door when it strikes against the door frame. In this way, the device 1000 is supported on the door in the area of the blocking means 1001, so that the occurring forces are transmitted directly from the blocking means 1001 to the door. This prevents the entire forces occurring being transmitted via the fixed connection between the device 1000 and the door, whereby this connection would be exposed to high loads, so that after a certain number of blocking operations the device would break off from the door.

In addition, the device comprises a return means 1201, which exerts a torque on the blocking means 1001. This torque counteracts a deflection of the blocking means 1001 about the pivot axis 1200 in the direction of the door when mounted on the door state. After a blocking operation, the blocking means 1001 is in a similar position as in FIG Fig. 12B shown. The torque ensures that the blocking means 1001 after the blocking process back into the in Fig. 12A shown position is moved. The return means 1201 may be, for example, a torsion spring.

In the FIGS. 13A and 13B is the pivoting operation of the blocking means 1001 about the pivot axis 1200 also good detect. FIG. 13A is a sectional view along the section line AA Fig. 11B , FIG. 13B is a sectional view taken along the line BB Fig. 11C ,
