Definitions

  • the invention relates to a device for locking doors according to the preamble of claim 1.
  • Uninvited peddlers or potential thieves not infrequently try to surprise the apartment owner by putting their foot between the door and the door frame after opening a small gap in the door and entering the apartment in a flash. The apartment owner is then usually so annoyed that he can no longer effectively counter the uninvited visitor or close the door. Older people in particular are often helplessly exposed to the group of people mentioned
  • a disadvantage of this door barrier is that it is visible to the uninvited visitor. In addition, it is not a major obstacle, because a firm push or jostling ___ often enough to tear the chain out of its attachment.
  • a door stop which has a wedge-shaped element which slides under the edge of the door when the door is opened, and thus a further one Opening prevented (US-A-1 035 264).
  • This door stop has two parts, one of which is screwed to the door, while the other part is inserted into the first part when not in use. In operation, the second and wedge-shaped part is removed from the first part and pivoted through 90 degrees about an axis of rotation. The connection between the two parts is maintained by means of a special guide cone even when the door with the first part shifts when opened relative to the second part lying on the floor.
  • the production of this known door stopper is very complex since it consists of several geometrically complicated parts.
  • a first part is also arranged in the lower region of the door and a second part is folded out of the first part so that it lies on the floor and functions as a locking wedge (US-A-1 297 189) .
  • This door stopper is complicated, u. a. because it needs a connecting element between the two parts, which at a relative
  • a relatively simple door stop wedge is also known (DE-U-9 311 237).
  • This door stop wedge has a run-up surface for the lower edge of a door leaf and a spring leaf with which it rests on the floor. When the door leaf opens, this spring leaf is compressed and acts as a wedge that prevents the door from opening further.
  • the disadvantage here is that the door stop wedge is not attached to the door, so that it must be deposited in another place. If the door is to be locked in a flash because an uninvited and intrusive visitor is to be kept away, it is hardly possible to quickly get the stopper from the other place and push it under the door.
  • a two-part door stopper is also known, one part of which is connected to a door, the other part of which is wedge-shaped and can be pushed under the door (US Pat. No. 2,798,755).
  • the connection between the two parts takes place here by means of a thin surface plate which is bent at an obtuse angle and which can be pivoted about an axis against the force of a leaf spring.
  • the wedge-shaped part lying on the floor does not require any devices for guiding guide brackets or the like, this multi-part door stopper is nevertheless constructed in a very complicated manner.
  • the wedge-shaped part is far from that and is disturbing.
  • the invention is therefore based on the object of creating a very simply constructed device according to the preamble of patent claim 1, which is also visually appealing.
  • the advantage achieved by the invention is, in particular, that the natural position of a foot of the apartment owner when opening a door is sufficient to prepare the door lock to a certain extent, pushing the door in by a certain amount triggers the lock.
  • the device according to the invention does not have to be screwed onto the door leaf or door frame. It is sufficient to attach them to the back of the door using a double-sided adhesive film. This also makes it easy to remove the device from the door if this should become necessary due to a move or the like.
  • Another advantage of the device according to the invention is that it is simple and inexpensive to manufacture.
  • FIG. 1 shows a door with a device according to the invention
  • Figure 2 is a perspective view of a portion of the door with the device according to the invention.
  • Fig. 3 is a side view of a door leaf with an inventive
  • FIG. 4 shows a view according to FIG. 3, but with the lock activated;
  • FIG. 5 shows a sectional view AA according to FIG. 3;
  • 6 shows a variant of the device according to FIG. 1, which is suitable for doors which are at a very large distance from the floor;
  • 7 shows a further variant, which has an additional latching;
  • FIG. 8 shows the device according to FIG. 7 in a latching position, with a force acting on the device in the horizontal direction;
  • 9 shows the device according to FIG. 7 with additional spiral springs;
  • FIG. 10 shows the device according to FIG. 8, with a force acting vertically in order to achieve a latching;
  • FIG. 11 shows a section BB according to FIG. 7;
  • Fig. 12 is an assembly aid made of cardboard, which can be supplied together with the device according to the invention.
  • a wall 1 and a floor 2 are indicated in FIG. 1, a door frame 3 with a door leaf 4 being located in the wall.
  • the door leaf 4 has a handle 5 and a lock 6 with a key 7.
  • the exterior or the stairwell is marked with 8.
  • a device 10 according to the invention is shown on the inside of the door leaf 4 in the lower region and in the vicinity of the door rebate 9. If a visitor presses the door leaf from the outside inwards - which is indicated by the arrow 11 - and is approximately in the position 12 the tip of a shoe of the apartment owner, not shown, the door is blocked by the device 10 against further opening because the shoe exerts a force on the
  • Exercises device 10 and thereby activated.
  • the apartment owner who opens the door 4 a gap would stand with his right foot between the door frame 3 and the door leaf 4, while his left foot would be close behind the device 10. This left foot would be the "activation foot”.
  • FIG. 2 shows the device 10 according to the invention for locking a door in more detail, specifically in connection with a door leaf 13 which can be rotated counterclockwise, which is indicated by an arrow 14.
  • the distance between the door leaf 13 and the floor 2 is denoted by a.
  • the device 10 has a web 15, 16 which is glued to the inside of the door leaf with a double-sided adhesive film or the like.
  • the web 15, 16 is optically divided into two halves 15 and 16 by a stiffening rib 28; it merges into a U-shaped part with two parallel legs 17, 18, a leg 19 perpendicular thereto and a curved leg 20. All of these legs 17, 18,
  • 19, 20 consist of an elastic material, preferably plastic, and together form a unit.
  • the leg 18 forms the underside of a wedge 33, which is provided with an inclined surface 21, a stabilizing web 22 and a stop lug 23.
  • the Knock nose 23 is to a certain extent the continuation of a rear web 29 which runs parallel to web 22.
  • an upward slope 25 is provided, the slope of which corresponds to the slope of the wedge 33.
  • the legs 17, 19, 20 of the device 10 which are preferably made of an elastic plastic, bend and the oblique surface 21 abuts the slope 25. Since this slope 25 is rigid and therefore as
  • Guide element for the wedge 33 acts, the surface 21 and with it the leg 18 of the wedge 33 is pressed down.
  • the disk 24 made of rubber thereby presses firmly in the direction of arrow 27 on the floor.
  • the device 10 abuts the shoe tip 31 of the apartment owner in a short time. As a result, the tip 32 of the wedge 33 comes under the bevel 25 and is pressed down by it.
  • the device 10 looks as it is shown in FIG. 4, ie the webs 17, 20, 19 are deformed, and the wedge 33 is located with its tip 32 or its front area under the door leaf 13.
  • the rubber washer 24 now adheres firmly to the base 2 and causes the wedge 33 and therefore the door leaf 13 to no longer be able to be moved inwards.
  • a further push against the door leaf 13 in the direction of arrow 30 thus remains unsuccessful, ie the door cannot be pressed inwards and thus opened.
  • the door leaf 13 is raised by the wedge 33 and the bevel 25 when the force 30 acts.
  • the lifting of the door leaf is normally limited by the door frame. If there is no such limitation, the lifting of the door leaf 13 is ended at the latest when the bevel 25 abuts the stop 23. This stop 23 thus prevents the bevel 25 from being pushed over the wedge 33 and between the webs 29 and 19 hang
  • Fig. 5 shows a section A-A (Fig. 3) through the device 20. It can be seen here that the wedge 33 has two intersecting stiffening webs which are divided into partial stiffening webs 22, 36 and 34, 35, respectively.
  • FIG. 6 shows a device similar to that in FIG. 3, but with an additional element 40 with which a possibly very large distance between the lower edge of a door and the floor can be reduced.
  • This element 40 preferably has a plastic or rubber profile 41 which is pushed into a corresponding guide groove 42 which is provided at the lower end of the web 28.
  • the shape of the profile 41 can be adapted to the respective conditions. It is only important that this profile 41 can be inserted into the guide groove 42.
  • FIG. 7 shows a variant of the device shown in FIGS. 2 and 3.
  • the rubber pad 24 is pulled up around the edge 45, which brings about better adhesion stability of the rubber pad on the leg 18.
  • a web 51 is provided which carries a projecting part 52.
  • a further web 53 with barbs 54 to 58 is provided, which can engage with the projecting part 52 of the web 51.
  • FIG. 8 shows how the device 10 latches when a force is exerted on the device 10 in the horizontal direction with the foot 31.
  • This force causes the leg 19 to bend in the region 20, as a result of which the leg 17 comes into an inclined position.
  • the web 53 with the barbs 54 to 57 thus moves downward, and the lowermost barb 57 engages under the part 52, so that the device remains in the position shown.
  • the additional latching is particularly advantageous if the door - for example when going into the basement - is to be left open a little without being closed by a draft. As a result, the door can be locked in any open position relative to the floor.
  • the device according to FIG. 9 essentially corresponds to the device according to FIG. 7. However, additional spiral springs 60, 61 are provided, which are supported with their ends in projections 62, 63 and 64, 65, respectively. The elasticity of the device 10 can be increased by these additional springs 60, 61.
  • FIG. 10 shows the same device 10 as FIG. 8. However, it illustrates that a vertical force also leads to locking.
  • the owner's shoe 31 presses in the direction of arrow 70.
  • Arrow 69 shows the direction of movement of the web 53 indicated
  • FIG. 11 shows a section B-B through the device 10 according to FIG. 7.
  • the projecting part 52 can be seen here, which is gripped by a barb 57.
  • This barb is arranged on the web 53, which in turn is attached to the plate 68 or is a part thereof.
  • a mounting element 70 is shown in FIG. 12, which preferably consists of cardboard and five parts connected to one another.
  • 71 denotes a square base part, which has a trapezoidal flap 72 to 75 on its four sides. These flaps 72 to 75 are folded upward in the illustration in FIG. 12. If you turn the element 70 by 180 degrees, its tip reaches the
  • the assembly element 70 is sold together with the device 10 in a box, so that the buyer does not need any special assembly aid.
