Description

  The present invention relates to a handle such as a door, and in particular, the handle can be used for unlocking a door of an automobile and opening the door at the same time, and the door is erroneously opened in the event of an accident. The present invention relates to a lever handle provided with a safety device that is automatically made according to an acceleration force to prevent this from occurring.

  EP 1 556 569 in the name of the same applicant as the present application discloses a handle provided with a lever which can be rotated in a frame fixed to a door of a vehicle. The lever is mechanically coupled to a rocker that can rotate within the frame when the lever is pulled to unlock the door. The swing body is provided with a shoulder portion, and the shoulder portion is suitable for being restrained by a stopper piece of a fixing member having a pendulum provided with an inertia mass body. For this reason, the stopper piece restrains the shoulder while a strong oscillation is caused to the pendulum by the inertial force that pushes the inertial mass acting on the inertial mass. With this configuration, since the inertial force that pushes the lever acts on the lever while the automobile is undergoing a side collision, the handle is accidentally opened, and thus the door cannot be opened.

  However, this known handle fixing member does not always work accurately. This is because the pendulum may return to its normal position during a car crash, for example, when the acceleration acting on the inertial mass changes suddenly or the pendulum rebounds. . In other words, it is not always possible to synchronize the action of the inertial mass with the movement of the lever and / or to keep the pendulum in a position to fix the handle for a sufficient time.

  The object of the present invention is therefore to provide a handle which does not have the above-mentioned drawbacks. This object is achieved by a handle whose main features are disclosed in claim 1 and whose other features are disclosed in subsequent claims.

  Due to the influence of the magnetic member and / or the ferromagnetic member provided on the steering wheel according to the present invention, the stopper piece is attracted toward the shoulder while the pendulum is swinging. Stays in a fixed position until it is finished. Thereafter, since the elastic means acts on the rocking body and acts on the same pendulum, the shoulder is returned to the initial position. With this configuration, the handle is always locked during the collision, and is automatically unlocked when the collision ends.

  According to a particular form of the invention, the magnetic member and / or the ferromagnetic member described above preferably comprises a permanent magnet and a metal member fixed to the stopper piece and fixed to the shoulder or vice versa. It may be. For this reason, known handles can also easily be provided with the device according to the invention.

  Further advantages and features of the handle according to the invention will also become apparent to those skilled in the art from the following detailed and non-limiting description of embodiments of the invention with reference to the accompanying drawings. .

Figure 3 shows a longitudinal section of the handle in the normal position. Fig. 2 shows a cross-sectional view of the handle of Fig. 1 along the plane II-II. Fig. 5 shows a longitudinal section of the handle in the collision position. Fig. 4 shows a cross-sectional view along the plane IV-IV of the handle of Fig. 3;

  1 and 2, it can be seen that the handle according to the invention comprises, in a known manner, a frame 1 suitable for being fixed, for example, on the back side of the outer surface of an automobile door 2. The frame 1 is provided with a transverse pin 3 that acts as a fulcrum. And the extension part 4 by the shaping | molding of the lever 5 can rotate centering | focusing on the crossing pin 3, and the lever 5 is suitable for being pulled outside in the direction of arrow 6 in order to open the door 2. ing. Therefore, the lever 5 rotates around the first axis 7 that is substantially parallel to the rotation axis of the door 2. An attachment portion 8 is provided at the other end of the lever 5, and the attachment portion 8 protrudes into the frame 1 and includes a recess 9, and a tongue 10 is rotatably engaged with the recess 9. The tongue 10 protrudes from one side surface of the oscillating body 11, and the oscillating body 11 can rotate within the frame 1 about a second shaft 12 that is substantially perpendicular to the shaft 7. According to this configuration, the lever 5 is mechanically coupled to the rocking body 11, so that when the lever 5 is pulled, the rocking body 11 rotates about the shaft 12. A coil spring 13 is arranged on the rocking body 11 so as to be coaxial. The oscillating body 11 is returned to the original position together with the lever 5 by the coil spring 13 when the lever 5 is not pulled any more. The swinging body 11 is further connected to a lock release mechanism (not shown) of the door 2, so that the door 2 can be opened by further pulling the lever 5. The above-described connection is performed using, for example, a cable (not shown) that is pulled by the rocking body 11 while the rocking body 11 is rotating.

  The rocking body 11 is preferably provided with a cam surface 14 on which the tappet 15 can slide. The tappet 15 is disposed at one end of an arm of a fixed member that includes a pendulum 16 that rotates relative to the frame 1 or the main body integrated with the frame 1. Therefore, the pendulum 16 swings around a third shaft 17 that is substantially parallel to the shaft 7 about which the lever 5 rotates, when the oscillator 11 rotates about the shaft 12. An inertia mass body 18 is provided at the other end of the pendulum 16, and the inertia mass body 18 preferably has a flat shape and is arranged near the center of the frame 1. The spring means 19, in particular a coil spring arranged so that its longitudinal axis is substantially perpendicular to the axis 17 between the pendulum 16 and the frame 1, exerts a force on the pendulum 16, Press toward its normal position. This normal position is a position where the tappet 15 is urged and pressed against the cam surface 14 of the rocking body 11. The swinging body 11 is preferably provided with a shoulder portion 20, which is disposed at a distance from the cam surface 14 by a distance larger than the height of the tappet 15 of the pendulum 16. Therefore, the tappet 15 passes under the shoulder 20 without contacting the shoulder 20 when sliding on the cam surface 14. On the other hand, the tappet 15 acts as a stopper piece by stopping the shoulder portion 20, particularly when the pendulum 16 is separated from the cam surface 14 due to the swing of the pendulum 16, thereby preventing the swinging body 11 from rotating. In normal use, when the lever 5 is manually pulled in the direction of the arrow 6, the rocking body 11 rotates in the direction of the arrow 21, so that the tappet 15 moves over the cam surface 14 without interfering with the shoulder 20. Slide.

  According to the present invention, the tappet 15 and / or the shoulder portion 20 is provided with a magnetic member and / or a ferromagnetic member. In particular, the permanent magnet 22 is fixed to the shoulder portion 20, and the metal plate 23 is attached to the tappet 15. Is fixed. For this reason, when the tappet 15 restrains the shoulder portion 20, the magnetic member and / or the ferromagnetic member attracts the tappet 15 toward the shoulder portion 20.

  Referring to FIGS. 3 and 4, in the event of an accident, if the lever 5 is subjected to a thrust force that attempts to open it in the direction of arrow 6, the inertia mass 18 is also thrust the same. As a result, when the pendulum 16 overcomes the force of the elastic means 19, the pendulum 16 is swung so that the tappet 15 is moved in the direction of the arrow 24 and away from the cam surface 14. In the new position, the tappet 15 stops and fixes the shoulder 20 when the swinging body 11 is pulled by the lever 5 and starts to rotate, so that complete rotation of the swinging body 11 is prevented. Since the oscillating body 11 cannot rotate any more, the unlocking mechanism of the door 2 is not operated. For this reason, it is prevented that the door 2 is opened accidentally. At the same time, the tappet 15 is attracted toward the shoulder 20 due to the influence of the permanent magnet 22 and the metal plate 23, so that the pendulum 16 is kept at the position of the collision, that is, the state where the tappet 15 is pressed against the shoulder 20. To be kept. At the end of the collision, the lever 5 is no longer subjected to acceleration, so the lever 5 no longer applies moment to the rocking body 11 and the spring 13 can rotate the rocking body 11 slightly. Thereby, the permanent magnet 22 is moved in a direction away from the metal plate 23. The attractive force between the tappet 15 and the shoulder 20 increases so that the elastic means 19 can expand again. As a result, the tappet 15 is released from the shoulder 20 and the door 2 can be opened by pulling the lever 5.

  To the embodiments of the invention disclosed and exemplified above, possible modifications and / or additions within the scope of the invention may be made by those skilled in the art.
