Description

Movable wall

description

The invention relates to a portable wall, which consists of individual Tür¬ or wall elements that serve to lock a building or part of the building. In this case, such portable walls are shifted from their lined-up arrangement into a parking position on the side or into a so-called train station during the usually prevailing business hours. The door or wall elements are suspended from a running rail attached to the ceiling. The individual door or wall elements can be made of all-glass door leaves with a profile serving for fastening in the upper area and serving for locking in the lower area, or they can also be used as framed elements. Glass panes are then preferably located within the framed elements.

DE 40 41 925 describes a movable, hanging wall consisting of individual elements. The individual elements are stored by so-called carriages, which are present twice on each individual element. The carriage is fastened to a profile attached in the upper area of the element. These carriages are guided within a running track attached to the ceiling. The ceiling rails are constructed so that the carriages are located within the rails so that they are not visible to the user. In this case, lateral guide rollers on the carriage take over an exact guidance, and in addition to the guide rollers there are also idler rollers.

Such a portable wall has become known, for example, from the 'DORMA HSW-R' documentation. These sliding glass fronts are used for this. Safely protect shop windows and entrances to shops and restaurants and conservatories against drafts and rain. The individual elements become within a parking position into which the sliding sashes can be inserted in a space-saving and inconspicuous manner spent for the period when the entrance front should be free. The sliding sashes are not guided in the floor, which prevents tripping edges and dirt traps in the floor. Locks, locks and other accessories can be found within a profile that occurs in the area near the floor and is fastened to the individual element. The locking is carried out manually, ie there are sockets for locks or striking plates for locks or for the bolt lock in the floor, into which by pressing a button on each retracted wing - after business hours - these are brought back into their lined up position Elements are securely attached. This type of determination is very complex because each wing must be fixed.

A locking system for individual doors that are automatically locked via a locking bolt has become known from US 3,143,760. The locking bolt embedded in the upper frame of a door works together with a rotatably mounted lever system which is spring-loaded. On the lever system there is an actuating lever protruding from the area of the door frame, which at the same time as the door moves into the closed position can at the same time latch the bolt into a hole in the door leaf. After the locking bolt has snapped into a socket located in the door wing, the door wing is locked.

The object of the invention is to automate the locking of the individual displaceable elements, which is very expensive to operate manually.

The object is achieved in that when at least two door and / or wall elements meet, they are locked in the floor by a positive lock. This is possible because there is a locking device with a plunger then connected in each case in the lower base profile on one end face. The plunger automatically actuates a locking bolt when a wing front side hits another wing front side, which is pressed into a ground sleeve embedded in the floor. The locking bolt is through a spring element is loaded in such a way that when the plunger is not actuated, the locking bolt is retracted within the locking device and thus within the wing. Thus, if the locking bolt is not actuated, it is automatically pulled out of the ground sleeve.

A locking bolt is mounted vertically in a bore within a locking device. This locking bolt is spring-loaded, so that it is retracted by a plunger within the locking device when not actuated. A horizontally working plunger with connected control plate interacts with this locking bolt. The control plate is horizontally slidable in a pocket within the locking device. In the non-actuated state, the tappet protrudes from the locking device and thus from the wing. There is an opening within the locking device in the same axis as the locking bolt moves, through which a guide pin passes. This guide pin also penetrates through the control plate, namely through a control slope in the form of an opening.

Due to the horizontal movement of the ram, i.e. the plunger is pressed into the wing, the coupling pin and the control bevels of the control plate also force the locking pin out of the locking device and thus out of the wing, which leads to the locking pin penetrating into the ground sleeve located inside the floor , ie When the locking bolt is locked in the floor in a ground sleeve, the guide pin reaches its lowest point within the vertical opening and also the control bevel.

When two wing edges meet by moving, the plunger is thus first immersed in a bore in the impinging wing and then, due to the forced movement, press the locking bolt out of the locking device and at the same time the plunger is pressed into the locking device. Due to the dimensional coordination, however, the tappet remains out of the locking device by an amount, namely the depth of the bore of the adjacent wing out and at the same time achieves a locking of the two clashing wings with each other

Further solutions to the problem then exist that the locking bolt is loaded either by a spring element to the effect that, in the absence of the plunger, the bolt is automatically pulled out of the base sleeve. In addition to the mere use of a spring element, can also be used in conjunction with a lever system, with a spring attached to it, for better power transmission, the bolts are pulled out of the sleeve during un-locking. In an embodiment of the inventive idea, however, it is also possible to dispense entirely with the use of spring elements, in the form that one displaceable element, on each side a plunger with a positive guide and on the opposite side the corresponding locking device is present, the plunger, which has a fork-shaped recess and runs from top to bottom, strikes a wing, so is automatically over a n pin, which is located on the locking bolt, takes the locking bolt with it and prints it downwards out of the base profile strip, and slides it into the sleeve located in the base. The forked, oblique course of the driver thus holds the locking bolt in the locking position. If a displaceable wall element is pushed back into the parking position with the driver, the driver moves out of the adjacent skirting board of the next wall element at the same time due to the shape of the locking bolt automatically pulled out of the locking position, ie pulled out of the base sleeve. So that the locking bolt is now fixed in this position within the baseboard, a laterally attached retaining pin loaded by a ball can hold the locking bolt within a circumferential groove to be engaged. The release force can be adjusted via the retaining pin

A locking device constructed in this way is able to automatically lock sliding wall elements invisibly to one another and at the same time securely lock them in the floor area. This eliminates the otherwise manually operated locking member, which is a huge relief for people. In the case of the object according to the invention, it is also not necessary to use an additional tool for locking the individual door or wall elements to one another.

The invention is explained in more detail with reference to several possible schematically illustrated exemplary embodiments. It shows:

A movable wall in principle is shown in Figure 1. A running rail 1 is fastened to a ceiling 41 of a building in a non-positive and positive manner. Within the running track there is a suspension, which consists in the fact that devices, not shown, are present on the supporting profiles 4 of the individual wings 2, which make it possible to move the individual elements of the wing 2. To simplify the description in the following, only wings will be mentioned, but in principle it is possible to produce such movable wall elements from any suitable material, in particular glass. It is irrelevant whether it is framed or unframed individual elements. In the area near the floor, the wings 2 are provided with a base profile 5. The first wing of the relocatable wall, namely wing 42, is secured by a lock 30 set in front of a wall 29. The adjoining wings 2 are each locked to one another and also at the same time in the base 3 by means of a locking device. This takes place in such a way that the individual wings 2 are brought into the movement direction 19, and when two wings 2 meet, locking occurs simultaneously with one another and with the floor.

FIG. 2 shows the locking device according to the invention, in the locked state, where the locking pin 21 is located within the base sleeve 25, which is located in the floor 3 and has a blind bore 26, and the end of which is connected to the floor 3 via a fastening 27 is firmly connected. For better insertion of the locking bolt 21 there is a chamfer 24 at its exiting end

The Verπegelungsvorπchtung 6 consists essentially of a base body 7, in which there is a vertical bore 10, into which a slide bearing 23 has been pressed for better guidance of the Verπegelungsbolzens 21. The locking bolt 21 has a larger diameter in the interior of the base body 7 in addition to its emerging diameter. This is necessary so that the locking bolt can also be brought into a rest position by a spring 14. The spring 14 is supported in the basic body 7 in the bore 10 on one end of the bore 32 and on the other hand against a shoulder 31 which is located on the locking bolt 21. At the end of the locking bolt 21, a guide pin 12 is inserted in this in a force-fitting and positive manner. The length of the guide pin 12 is such that it extends beyond the diameter of the locking bolt 21. The ends of the guide pin 12 protruding from the locking bolt 21 are displaceable in an opening 13 which is located vertically within the base body 7. In addition, at the end of the locking bolt 21 there is a recess, not shown. Within this recess there is a control plate 22 which can be displaced horizontally within the base body 7. The control plate 22 interacts with a plunger 11, which is also vertically displaceable and protrudes from the wing 2. The plunger 11 is non-positively and positively connected to the control plate 22. Inside the control plate 22 there is a control bevel 28 which is designed as a breakthrough. The guide pin 12 also penetrates through these control bevels 28 and thus causes a vertical displacement of the locking bolt 21 with the help of the control bevels 28 when the plunger 11 is actuated in the horizontal direction. Both the control bevel 28 and the opening 13 are dimensionally sufficient coordinated with one another so that clean horizontal sliding within the pocket 20 and also within the locking bolt 21 of the control plate 22 is possible.

The tappet 11 has at its end emerging from the wing a head 18, at the end of which there is a chamfer 17 which, for better immersion of the impinging second wing, dips into a bore or recess 16 in a cover plate 15. By immersing the head 18 in the adjacent wing a locking of the colliding wings is effected with each other. If the wings are moved further in the direction of movement 19, the locking bolts 21 penetrate into the base sleeve 25 due to the positive guidance via the control bevels 28 and thus simultaneously lock the wings in the base area.

The entire locking device 6 is fastened by means of fastenings 8 on an end face of a wing 2. The side closure forms a cover plate 9 through which the plunger 11 penetrates.

The idea according to the invention can be used both in the case of manually displaceable and automatically displaceable wall elements or sliding walls. It also guarantees that the individual elements are always locked to one another and to the floor when the elements face each other. Another locking in the unlocked state is shown in FIG. 4. Each of the wings 2 has a plunger 37 on one side of the base profile 5 and an opening 39 on the opposite side, behind which the locking device for locking the individual wings 2 is located. By immersing the plunger 37 in the opening 39 via the direction of movement 19, a locking of the two wings 2 meeting one another is achieved. The plunger 37 consists, for example, of a protruding part which at the same time has at least one contact surface 38 which bears against the end face of the base profile 5. Within the base profile 5 there is a fastening leg of the plunger 37, which is fastened invisibly within the base profile 5 by means of fastenings 35 in a non-positive and positive manner. On the opposite side there is a locking device within the base profile 5, which essentially consists of a holding piece 48 with a locking bolt 21 guided therein. The locking bolt 21 is guided in a vertically guided bore 47 in such a way that when it emerges from the base profile 5 it has the possibility of penetrating into a ground sleeve 25 embedded in the floor. In this case, the locking bolt 21 has a chamfer 24 on its front side for better immersion in a blind bore 26 in the base sleeve 25. The ground sleeve 25 is securely fixed in the floor 3 via a fastening 27. At the same time, a lever system consisting of the levers 42, 43 is connected to the locking bolt 21. The lever 43 is rotatably connected at one end to the locking bolt 21 and at the other end at a pivot point 45 to one end of the lever 42. The other end of the lever 42 is non-positively connected to a bracket 46 at a pivot point 44. At the same time, the lever 42 is provided with a spring 40 which holds the two levers in the rest position in such a way that the locking bolt is retracted within the base profile 5. The two levers 42, 43 have an angular position in such a way that the fulcrum 45 points to the opening 39 within the base profile 5. If the plunger 37 of the second wing 2 hits the levers 42, 43, a vertical force is exerted on the locking bolt 21 by the applied force from the horizontal direction, which causes the locking bolt 21 to be pressed out of the holding piece 48 and thus out the base profile 5 causes. This locking position can be seen in FIG. 5. The holding piece 48 is connected to the base profile 5 by means of fastenings 34 in a non-positive and positive manner.

In an embodiment of the concept according to the invention, a further type of interlocking with one another and in the base region of the wings 2 is reproduced in detail in FIGS. 6 and 7. As already described, there is a driver 51 on one side of the base profile 5 and a locking device on the opposite side of the same wing. The driver 51 is designed so that it is non-positively and positively connected to the base profile 5 within the base profile 5 via fastening 49. The emerging part of the driver 51 has a fork 52, which is characterized by such a course that the open end of the fork 52 is laterally above, and the course of the fork runs obliquely downwards. At the beginning of the fork 52 there are roundings 54. Furthermore, there is an inlet slope 53 which is located below the fork 52 on the driver 51.

The Verπegelungsvornchtung consists of a holding part 64 which is connected via fastenings 58 within the base profile 5 non-positively and positively. The holding part 64 also has a bore 65 in which a locking bolt 55 is displaced vertically. The Verπegelungs¬ bolt 55 has at its exiting end a chamfer 57, which allows a problem-free immersion in the ground sleeve located in the ground. So that the locking pin 55 can be held in this position, there is an adjustable holding pin 60 on the side. This holding pin has a spring-loaded ball at its front end, which engages in a circumferential groove 59 which is located in the locking pin 55. If the locking pin 55 is now pushed out of the base profile 5, the holding force present in the holding pin 60 is simultaneously released and the locking pin 55 can be pressed into the locking position. In the upper part of the locking pin 55 there is a driver pin 56 transversely to the locking pin 55. This driver pin 56 enables connection with the driver 51 and the fork 52 located therein is an automatic method of the locking bolt 55.

When the driver 51 strikes the wing 2 located in front of it, by immersing the driver 51 in an opening 61 in the wing 2, the two wings 2 meeting one another are locked. At the same time, the driver pin 56 comes into contact with the driver 51, which, due to the inclined fork 52 inside the driver 51, means that the locking bolt 55 is forced out of the base profile 5. This is particularly visible in FIG. 7, where both the wings 2 are locked to one another and in the floor 3. Due to the positive guidance via the fork 52, it is not necessary that the individual wings 2 have to be locked manually. Even when two wings 2 move apart, the locking bolt 55 is automatically pulled out of the base sleeve 25, which ensures unlocking in the base. If the displaced wing 2 is actuated further, the locking of the wings with respect to one another is also released at the same time.

The idea according to the invention can be used both in the case of manually displaceable and movable wall elements which can be moved automatically. It also guarantees that the individual elements are always locked to one another and to the floor.
