Abstract

The present invention relates to a device fixed to the ground, making it possible to damp and stop the movement of the doors. The device in the form of a cap, consists of a part (A) which, when struck by a door leaf, slides on a part (B) fixed to the ground by screws or bolts (C) and ( E). Once contact with the door is complete, part (A) returns to its initial position, by the effect of a spring (G), giving the impression of forming with part (B) a one-piece cap. . This device as it is designed, given its shape and height (2cm max), is particularly suitable for braking and stopping door leaves in the general housing sector by avoiding the risk to be a goal for people's feet.

Description

The present invention relates to a device, placed on the ground,

  to dampen and stop the movement of doors

  at the opening, without constituting an obstacle for people.

  Frequently used devices allow, on the one hand, to serve as simple stops for doors placed on the floor, in which case they constitute an obstacle for the feet, and can thus cause people to fall. which, these devices on the ground are placed against the walls. Their role is then to avoid that the handles of the doors, when the latter are in movement, are in contact with the walls. On the other hand, they make it possible to brake, d '' stop the doors and bring them back to the closed position.This is the case with door closers generally placed in the upper part of the doors. The door being held only in the upper part, there is a 15. risk of leaf deformation especially. on metal doors of large height and width. Indeed, opening a door requires the application of a force

of pushed on the leaf.

  When the door in rotation, on the hinges, in the direction of opening, is stopped at its upper part on which the braking force is exerted, there is created a reaction force opposite to that of the thrust La lower part which does not undergo such efforts, tends to continue its course in the direction of opening, driven by part of the initial thrust force Contrary forces thus created are exerted on the upper and lower parts of the leaf and result in the deformation of the leaf, the bottom and the top no longer being aligned on the same axis. The advantage of this device is to remedy the

  disadvantages listed above.

  By its shape (a cap without projecting element) and its height (2cm max), the device can be placed on a passage, without risk of constituting an obstacle for the feet of people. Associated with traditional door closers, it can brake and

  35. stop the doors by limiting the risk of deformation.

in the operating principle.

  - Figure 10 shows a top view of a second variant of the

device relating to form.

  - Figure 11 shows in profile view, the same second variant of

  15. device relating to form.

  Indeed, the cap-shaped device consists of a part (A) which, when struck by a door leaf, slides on a part (B) fixed to the ground by screws or bolts (C) and ( E). Once the contact with the door is finished, the part (A) returns to its initial position, by the effect of a spring 20. (G), giving the impression of forming with the part (B), a cap in a

single piece.

  The translation of the part (A) on the part (B) is carried out in the following way: -the part (B) comprises a machined hopper in the shape of a dovetail in which slides a part (D), also machined in the same 25. shape and integral with the part (A). The workpiece hopper (B) and the workpiece (D) can be machined so that the workpiece (A) slides on the workpiece (B), without it being possible to lift the workpiece (A), a once the device is mounted. (see fig 9) -the part (D) is connected to the part (F), integral with the part (B), by a

30. spring (G).

  -when a thrust is exerted from left to right on the part (A) (see fig 6), it is driven to the right while opposing a resistance force through the spring (G) which tends. When this force is intense, the part (A) in its translation is stopped using the part

  35. (D) which abuts on the part (B) fixed to the ground.

  - when the intensity of the force exerted on the part (A) is less than the return force of the spring (G), the part (A) slides in the opposite direction

  to return to its initial position by abutting on the part (C).

  The advantage of the translation of the part (A) is threefold: 5. -when it is struck by the leaf of a door, it brakes it through

of the spring (G).

  -the part (C) constitutes a major obstacle to the door leaf. When the part (A) is driven out, it uncovers the part (C) against

which the door abuts.

  10. - depending on the power of the spring force, the part (A) can impulse in

  back, a movement of the door in the closing direction.

  The shape of the pieces (A) and (B) can be declined in a variant (see figlO and 11) by stretching opposite, one from the other, the two

  hemispheres of the base cap.

  15. The dimensions of all the parts that make up the device are not

not limiting.

  As an indication, at the base the piece (B) has an approximate diameter of 12cm.

  The maximum height of the entire device remains less than 2 cm.

  This device, as it is designed, is particularly suitable for braking and 20. for stopping door leaves in the field of housing in general, in

  eliminating the risk of constituting a stop for people's feet.

Claims (2)

CLAIMS -1) Cap-shaped device with a maximum height of 2cm fixed to the ground, allowing, without risk of constituting a stop for the feet of people, to dampen and stop the movement of the doors upon opening, and initiate the closing movement, characterized 5.in that it consists of a part (A), which by moving on a part (B), under the effect of the force exerted by the leaf of a door, opposes a force created by the tension of a spring (G) fixed on a part (D) integral with the part (A), and on a part (F) integral with the part (B).   10. - 2) Device according to claim 1, characterized in that the part (B), fixed to the ground, by screws or bolts (C) and (E) comprises a machined hopper in the form of a dovetail, in which slides a male part (D), also machined in dovetail. 15. -3) Device according to claim 2, characterized in that the part (D) is integral with the part (A) which it slides   when a push is exerted on the latter.   -4) Device according to any one of claims   previous, characterized in that a spring (G) fixed on the part (D) 20. and on the part (F), itself integral with the part (B), brakes, by tightening, the translation of the part (A) which dampens and stops the leaf door.   -5) Device according to claim 4, characterized in that the spring, which relaxes, giving off a force opposite to the thrust, 25. when the door closes, slides, in the opposite direction, the part (A) which returns to its original position by stumbling on the piece (C).   -6) Device according to one of claims 1, 3, 4 and 5   characterized in that in the rest position it has a shape 30. cap without roughness.
