Abstract

A door stopper arrangement comprises a stop (6), limiting the opening angle of the door (1), window, or similar. The stop (6) is arranged on the wall and/or the floor (5) and can be retracted into the wall and/or the floor (5).

Description

The invention relates to a doorstop arrangement of the claim 1 corresponding type.

If doors hit obstacles when opening (for example, wall projections and the like), experience has shown that damage may occur to the door frames, door leaves or door hinges. To counteract such damage, in addition to designs in the band area, which are not advantageous because of the unfavorable lever arm high forces, at a greater distance from the pivot axis on the floor or the wall so-called doorstops (door buffers or stops) are provided so attached be that they are on reaching the maximum possible opening angle of the door leaf to avoid damage to the lock side of the wing and thus limit the opening movement of the wing.

However, such doorstops are also not free of disadvantages, for example, they represent a risk of tripping when they are on the floor. In an arrangement on the wall, it can also come to a "hanging" of passing people. In addition, when attaching such a door stopper on the floor or on the wall whose appearance is disturbed.

The object of the invention is therefore to provide a doorstop, which is effective only when opening the door, but otherwise poses no danger and does not affect the visual impression of the mounting surface.

This object is achieved by the reproduced in claim 1 invention.

Characterized in that the doorstop arrangement comprises a the opening angle of the door, the window or the like limiting stop, wherein the stop is disposed on the wall or the floor, the stop in the wall and / or the floor is retractable and thereby approximately flush with the Completing the surface of the wall and / or the floor, it is possible, on the one hand to ban the risk of stumbling and / or the risk of getting stuck by the outstanding stop or at least restrict and not affect the appearance of the mounting surface too strong.

The stop is automatically moved by means of movement from the retracted position to a retracted position as soon as a wing of the door, the window or the like when opening a certain opening angle, in particular a maximum opening angle exceeds.

Thus, with the door closed, the stop is in. Floor or wall recessed and protrudes out of the wall or floor only after opening the door sash. Therefore, with the door closed, there is no or only a very small elevation in the floor or the wall, which does not represent a danger location such as a trip.

Furthermore, the appearance of the floor covering or the wall paneling is not or only slightly affected by the retractable stop. It is conceivable in this context that the stop has the same surface structure and color of the bottom or wall to which it is attached.

From US-A-3 563 586 a gettungsgemäße doorstop assembly is known in which a locking pin can be electrically extended wherein the switch is disposed on the wall. There is a risk that the operation of the door stopper arrangement is omitted and the door is left to itself.

Preferably, the stop is arranged in a housing, which is embedded in the wall and / or the floor and thereby conveniently ends approximately flush with this. Thus, it is also prevented that the housing is a source of danger. Further, parts of the moving means may be arranged in the housing.

Thus, the penetration of water, dirt and the like is prevented in the housing, which would otherwise cause a malfunction of the stop itself or the movement means for moving the stop, the housing is provided with sealing means.

Preferably, the stop is in its extended position by electrical, electro-mechanical, hydraulic, pneumatic, mechanical moving means or the like or a combination of these movable. The movement of the doorstop can thus be done by all known types of drives.

The triggering elements preferably comprise mechanical means and / or sensors, in particular optical, mechanical or magnetic sensors, rotary encoders, sliding contacts, radio remote controls or the like. Thus, the greatest possible flexibility of the arrangement of the stop with respect to the door or the door size and also a trouble-free function is ensured and an adaptation to the individual circumstances of the respective door possible.

It is favorable when the triggering elements are at least partially integrated in corresponding band arrangements for doors, windows or the like. Also, the triggering elements at least partially integrated in the closing mocharlisms of the doors, windows or the like.

Further features, details and advantages of the present invention will become apparent from the following description. Show it:

In Figs. 1 and 2, as a whole with 100 designated door stopper arrangement is shown with the door closed, whereas in Figs. 3 and 4 corresponding views are shown with the door open.

The door 1 consists of a door frame 12 and a door leaf 3, which are arranged in a corresponding outbreak in the masonry 2. The door leaf 3 is hingedly connected to the door frame 12 via a band assembly 4, movably connected to a hinge axis S. In front of the masonry, somewhat laterally offset to the left from the door 1 in its opening direction, there is a doorstop 15 which consists of a housing 7 recessed into the floor 5, a housing cover 13 terminating approximately flush with the floor and the actual stop 6. The door stopper 15 or its housing 7 is offset so far to the left laterally in the opening direction of the door leaf 3, that the stop 6 limits the maximum opening angle 8 of the door leaf 3.

In Figs. 1 and 2, the stop 6 is sunk in the sunk in the bottom housing 7 of the door stopper 15. The housing cover 13 is sloping flat to the sides, so that this is no danger spot despite a small survey against the bottom 5. Furthermore, its collection is less than the gap between the door leaf 3 and the bottom 5, so that the door 3 can pivot when opening on the housing cover 13 away and meets the stop 6.

If, as shown in FIGS. 3 and 4, the door leaf is opened about the pivot axis S of the belt arrangement 4 beyond a maximum opening angle 8, then the stop 6 of the doorstop 15 is lifted from the housing 7 sunk in the ground by means of movement 9 moved out, wherein the movement of triggering means 10 is triggered. The stopper 6 then limits the opening of the door leaf 3, so that in the example shown, the band assembly 4 does not hit the masonry 2 and is damaged.

The movement means may comprise electrical, electromechanical, hydraulic, pneumatic, mechanical means of movement or the like, or a combination thereof. Conceivable z. B. electric motors or Hubkolbenanordnungen.

In the illustrated, simplest case, the movement means comprise a spindle 9 located in the housing 7, on which the stopper 6 is turned on, wherein it is arranged in the housing 7 rotation safe, so that a rotational movement of the spindle 9 causes a vertical movement of the stopper 6. The spindle 9 is connected via a, by means of "dash-dot-dot" line indicated Bowden cable 11 with a not shown, lying in the belt assembly 4 device 10, in which the Bowden cable is coupled to the movement of the door leaf 3.

If the door is thus opened, the spindle 9 is rotated by means of the Bowden cable 11 and the stopper 6 is moved upwards. When closing the door leaf 3, the Bowden cable 11 moves in the reverse direction and the spindle 9 thus also turns the other way round, so that the stop 6 is sunk in the housing 7 in the bottom 5 again.
In this simplest case shown, the movement of the stopper 6 out of the housing 7 with the not shown, lying in the band assembly 4 means 10, in which the Bowden cable is coupled to the movement of the door leaf 3, causes. It can be z. B. act to a pulley arrangement which acts directly on the Bowden cable 11.

However, there may also be other single independent triggering elements, which may be, for example, sensors of all kinds, exceeding the maximum opening angle of the wing the movement means for moving the stop 6 trigger. Furthermore, rotary encoder or sliding contacts for triggering the movement means are conceivable. So z. Example, the use of a micro switch is possible, which is actuated upon reaching the maximum opening angle and thereby, for example, an arranged in the housing 7 electric motor for moving the stopper 6 controls. Analog would also be a pneumatic or hydraulic line instead of the illustrated Bowden cable 11 can be used. The hydraulic fluid would be pumped by the movement of the door leaf 3 in the housing 7 to raise the stop 6 there by means of a piston. Many other embodiments are conceivable.

If a direct connection of the triggering elements with the door stopper 15 is not possible or not desired, their connection can be carried out, for example via a radio remote control, ultrasound, infrared or the like.
