EP1790810A2 - A door stop integrable in a door panel - Google Patents

Abstract

The stopper has a door stopper plunger (2) with a plunger base (3) and an actuating mechanism, which has a hand operatable actuating body (6), a connecting unit (8) and a spring (4). The connecting unit couples the body with the plunger, and the spring pretensions the plunger or the base downward. The plunger is selectively movable and lockable in a raised resting position, and brought into a lowered operating position, in which the plunger bar is pressed under prestressing against a ground. An independent claim is included for a door leaf with a door stopper.

Description

The invention relates to an integrable in a door leaf doorstop or door arrester.

Known doorstops, as they have found entry into the practice, are placed on the door leaf and mounted on it are designed for foot control and have a usually provided with a ratchet mechanism, with the foot depressible in the stop position door stopper and a likewise operable with the foot release lever. Known doorstops are therefore robust and accordingly bulky. They have a visually disturbing effect and are therefore used almost exclusively on front doors and similar doors, but not on room doors or terrace or balcony doors in living rooms.

However, a need for doorstops on doors, patio doors and balcony doors would already exist, because often you want such doors, for example, for ventilation purposes, completely or partially open, without the risk that wind or draft hits the door in question or strikes and collisions causing damage to the door or door handle with furniture or other furnishings or the wall, causing damage or glass breakage to the door or furnishings or wall. Because of the strong optical interference of Türstoppem on such doors doorstops are not in demand and are in an adapted form also practically not available, and manages with unsuitable and visually disruptive means such as placed under the door wooden wedges or cords or chains for attaching the door on the wall, the latter allowing no locking of the door in an only partially open position.

However, attempts have been made to form doorstops integrated in door panels. For example, the German utility model describes this DE 1 780 520 from 1958 a doorstop, which is to be integrated into the rebate area of the door leaf and is coupled to the door handle. This doorstop has a provided with a brake rubber, biased by a compression spring downwards doorstop, which is coupled via a guided in Türblattfalz linkage with an outside of Scblosskasten arranged, connected to the square shaft of the doorknob lever. Upon depression of the door latch, the doorstop is lifted against the spring force and the door can be moved, and when you release the door handle, the doorstop occurs in each case action and locks the door in their respective position. However, this known proposal is unsuitable for several reasons. On the one hand, the arrangement of the linkage and connected to the square shaft lever laterally outside the lock box is not practical, since then next to the lock case in the door leaf must remain free, so that the lock box can not sit as stable in the door leaf, as the Case is when it is inserted into a just in its width corresponding Schlitzeinfräsung. On the other hand, this known proposal is unusable handling technology, since the door can only be moved while holding the door handle, which is impractical.

Another but also practice-remote proposal for a Türplattenintegrierten doorstop is from the German utility model DE 1805 041 known from 1960, where in turn provided with a brake rubber Türstopperstempel biased by a compression spring down and connected to a guided in Türblattfalz linkage, which ends up in a arranged on both sides of the lock box forklift. The actuation takes place via the doorstop, wherein upon depression of the latch, the doorstop is lifted over the linkage by means of a connected to the square shaft of the doorknob lifting arm and then engages a spring-loaded pawl in the lifted forklift, so that the doorstop in the raised position remains and the Door can be moved. To release the door stopper, the pawl must be moved upwards, whereby the pawl is disengaged from the lifting fork. However, the arrangement is such that even a slight and accidental lifting of the door handle pulls the release of the door stopper and the immediate blocking of the door, but the real problem is the arrangement of the actuating mechanism on both sides of the lock case with the result that on the one hand, the space for installation in a standard door is usually not sufficient and a thicker door leaf would be required, and that on the other hand, the lock box needed in its receiving opening in the door leaf on both sides free space for receiving the doorstop mechanism, so that the lock case can no longer be stably housed in the door leaf and only hangs on the strike plate, so would be mounted completely unstable.

Next is from the DE 1 968 078 a proposal is known in which a means of a compression spring biased in the opening direction door stopper can be depressed by an accommodated in the door lock mechanism cam lever by raising the door handle. However, this does not seem feasible with conventional door locks. Finally, out of the DE 1 947 291 a proposal is known in which a biased by a spring downwardly biased doorstop is connected via a steel cable with a lever which in turn is arranged laterally outside of the lock case and actuated by the doorknob.

All these known proposals bear the needs for using a conventional lock case, the stable installation of the lock case in the door, and practical handling is not sufficient account, so that it is hardly surprising that these proposals have found no input into practice.

The object of the invention is therefore to provide an integrable in the door panel and also easy to retrofit doorstop, which is easy to handle, on the door leaf is virtually invisible and allows the use of commercial lock boxes and door fittings.

This object is achieved according to the invention by the door stopper specified in claim 1. Advantageous Ausfühmngsformen and embodiments of the invention are specified in the dependent claims.

The door stopper according to the invention is designed as a doorstop and can be integrated in the rebate area of a door in the door leaf, so that it is completely invisible with its entire mechanism from both sides of the door leaf and therefore does not affect the door visually. The door stopper according to the invention makes it possible to fix the partially opened door in any desired position and regardless of any unevenness of the floor lying in the pivoting range of the door.

The doorstop according to the invention is, as I said, designed as Türantstopper and is similar to the known Türkantriegeln actuated, which is installed as an installation unit in the door rabbet down or up and has an actuatable by means of a pivot lever rigid latch which engages in an opening at the bottom or on the door frame to lock the door in its closed position. The Türantstopper invention can be used as well as conventional Türkantriegel with its own housing directly completely into a corresponding Falzaussparung the door panel. In this case, for more comfortable operation, without the user has to bend over, the actuating lever relatively high up in the door rebate, for example, be housed directly below a lock case. For this purpose, either a control lever, the Türstopperstempel and an extending therebetween connecting member common, extending over the corresponding height housing be provided, or operating unit and Türstopperstempeleinheit can be separated from each other installed in the door rebate and connected by a running in a channel within the Türfalzes connecting member be.

The door stopper according to the invention can also simultaneously perform the function of conventional Türkantriegel in which he can intervene in the closed position of the door in an existing there ground socket or bottom opening.

Figure 1 shows to illustrate the installation of the door stopper according to the invention in a perspective view of a door leaf TB, where you see on the door leaf only the door handle with the fitting. In the fold you can see the door lock, and in the lower area can be seen from the built into a cutout of the door leaf in the Türfalz doorstop TS only the cover plate with the operating lever (it is the embodiment described below with reference to Figures 2 to 4). Moreover, the doorstop is completely invisible, and especially from both sides of the door leaf forth from the doorstop is nothing to see.

Figures 2 to 4 show a first embodiment of the door stopper, in each case in a sectional view, so that the mechanism is clearly visible. FIG. 2 shows the doorstop in the direction of the cover plate (ie on the door rebate), and FIGS. 3 and 4 show the doorstop in a side view, specifically FIG Figure 4 in working position (door stopper lowered).

The doorstop has a housing 1 made of sheet metal, a Stopperstempel 2, a Stopperfuß 3 made of non-slip material such as hard rubber, a compression spring 4 and a punch screw 5. The stamp foot 3 is screwed with a screw, as shown, in the stamp 2 from below and thus optionally position variable. The stamping screw 5 is screwed from above into the stamp 2 and thus also optionally adjustable. The head of the punch screw 5 serves as a driver when lifting or holding the stamp in the inoperative position of the door stopper. An actuating lever 6 is rotatable about an axis 7 and formed as a double-armed lever whose longer lever arm forms the actuating handle and whose shorter lever arm is hinged at the upper end of a flat spring 8, whose lower end is bent and forms a disc 9. This disc 9 forms the upper abutment for the compression spring 4, which is supported with its lower end on the punch 2.

Figure 3 shows the doorstop in the inoperative position, wherein the actuating lever 6 is pivoted downward, so that the articulation of the flat spring on the actuating lever is located above the axis 7 and the disc 9 engages under the head of the plunger screw 5 and this and this over Holding the stamp 2 with the stamping foot 3 in a raised inoperative position. In Figure 4, the actuating lever 6 is pivoted upwardly, whereby the flat spring 8 is pressed down, so that the punch 2 can lower with the Stempelfuß 3 to the investment of the Stempelfußes 3 to the ground. The geometry is chosen so that when the Stempelfuß 3 is seated on the ground, there is still a certain amount of play between the head of the punch screw 5 and the disc 9, so that the stamp a certain höhenmäßiges movement clearance to compensate for uneven floors in the swivel range of Door has. The compression spring 4 is under bias (even with ineffective position of the door stopper) to press the stamp foot 3 against the ground.

In the illustrated embodiment according to the figures 2 to 4, the spring acts on the stamp 2. It thus biases the entire punch 2 together with the stamp foot 3 down. Deviating from this, it is of course also possible to form the stamping foot 3 movable by a certain distance relative to the punch 2, for example telescopically, and to arrange a compression spring between the stamping foot and punch. The flat spring or a similar link could then be connected directly to the stamp.

FIGS. 5 to 7 show a second embodiment of the door stopper according to the invention, FIG. 5 showing a side view in the rest position, that is to say with the door stopper raised, FIG. 6 a side view in the working position (door stopper die lowered), and Figure 7 shows a view of only the actuating lever area. The doorstop in turn has a housing 1, a Türstopperstempel 2 with a stamp foot 3 and a compression spring 4 and an actuating lever 6 which is pivotable about an axis 7. However, the housing 1 accommodates only the punch 2 and the compression spring 4, while the operating lever 6 is housed in a separate housing 11, which can be arranged at a greater distance, so for example directly under the door lock, in the door rebate and thus in a grip favorable position than in the first embodiment described.

The compression spring 4, which acts on the upper end of the punch 2, is supported by the upper end on a cover plate 12 of the housing 1. The punch 2 is connected via a tension member, for example in the form of a steel cable 13, with the short rear lever arm of the actuating lever 6. In the exemplary embodiment, the steel cable 13 is guided in the lower region of the housing 11 via a guide roller 14 (or a guide pin), so that the tension member 13 or the steel cable between the punch 2 and the guide roller always has the same orientation.

Figure 5 shows, as I said, the rest position. In this, the operating lever 6 is pivoted downward and the pulling member 13 is pulled up so that the punch 2 is raised and the compression spring 4 is compressed. In this position, the axis of the tension member 13 extends forward (in the drawing left) of the actuating lever axis 7, so that is locked by the tension of the tension member 13 by the compression spring 4, the actuating lever 6 in its position. Figure 6 shows the working position in which the operating lever 6 is pivoted upwardly, whereby the pulling member 13 is lowered and therefore the compression spring 4 can press the punch 2 down and press against the ground. Also in this position, the actuating lever 6, as can be seen from the drawing, fixed by the train of the tension member 13. The compression spring 4 is dimensioned so that, even when the plunger 2 is seated with the Stempelfuß 3 on the ground, still generates enough biasing force to press the Stempelfuß 3 frictionally against the ground.

The embodiment of Figure 8 is similar to that of Figures 5 to 7, but in this embodiment, the tension member is deflected with its upper, connected to the operating lever 6 end portion via an upper guide roller 15 downwards. The Function is thus similar to the function of the embodiment of Figures 5 to 7, however, in the embodiment of Figure 8, the actuating lever 6 is always the same orientation as the Türstopperstempel 2, namely, with raised punch 2 upwards and lowered into the working position Stamp (not shown) down.

In Figure 8 it is also shown that a part of the tension member, namely the lower, connected to the punch 2 part, may be formed by a rod or a rod 16, while only the upper deflected part of the tension member is designed as a steel cable or the like ,

Figures 9 to 11 show a further embodiment, which also works with a tension member, but instead of an actuating lever, an actuating slide 17 is provided and the pulley principle is applied.

It is in turn a housing 1 is provided, in which the movable doorstop 2 is arranged with the stamp foot 3 and a compression spring 4. The compression spring 4 is supported at the top of a fixedly arranged in the housing 1 abutment 18 and presses with its lower end on the stamp 2. A tension member 13, for example in the form of a steel cable is fixed with its one end to a fixed point 19 in the housing 1 , runs from there first down, then is guided around a guide roller 20 which is connected via a shaft 21 fixed to the punch 2, and then led upwards, where it is mounted on the actuating slide 17. The slider 17 is provided in its lower end with a transverse, on both sides protruding pin 22, whose two ends is guided in both sides of the slider 17 in the housing 1 slide guides 23 formed. The slotted guides 23 have at their upper ends in each case a slightly obliquely downward forwardly extending notch, in which the pin 22 in the uppermost position of the slider (Figure 10) engages and in this position, the raised position, ie the rest position of the punch. 2 corresponds, is locked by the spring-loaded tension member 13.

To bring the doorstop in its working position, the slider is simply pressed with the thumb, whereby the pin 22 pushed backwards and slightly upwards out of the notches and in the vertically downwardly extending slot portion of the Slotted guides 23 passes, so that the slide 17 can move down and thereby the guide roller 19 can lower with the shaft 20 and the punch until the stamp foot 3 rests on the floor, wherein the compression spring 4 then generates a contact force. To bring the doorstop back to its rest position, the slider 21 is pushed upwards with the thumb or a finger until the pin 22 engages again in the indentations at the upper end of the slide guides 23. Because the pulley principle is applied by the tension member 13 is guided over the associated with the punch 2 guide roller 19, only half the force is required to lift the punch 2 in the rest position, although a corresponding slide path is necessary.

In the illustrated embodiment, the housing 1 receives both the punch and the slider. It is understood that the punch and the slide can be arranged at a greater distance from each other and housed in two separate housings, so that the slide is in a convenient position in the door rebate and does not have to bend to actuate the user.

Fig. 12 shows a section through the front portion of a door leaf with built-in door stopper according to the invention, which is also usable as Türkantriegel. In the bottom there is an opening formed by a bottom sleeve BH, into which the stamping foot 3 of the type of embodiment shown in FIGS. 2 to 4 formed door stopper engages in its lowered position. Thus, the doorstop according to the invention can also perform the function of a conventional Türkantriegels, and doors with conventional Türkantriegel can be retrofitted by replacing the Türkantriegelels against a Türantstopper according to the invention. It is understood that the Türstopperstempel has a sufficient path of movement, so that he lowered between a raised position in which the Stempelfuß 3 is lifted out of the bottom sleeve BH, and in which the door is free to move under the bias of its biasing spring into a working position is, in which the stamp foot engages either at the location of the bottom sleeve BH in this or outside the ground socket is supported on the ground and determines the door in the selected position.
