Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking brake lever for switching between braking and non-braking by raising and lowering an operation lever (hereinafter, a brake lever unless otherwise specified in the text means a parking brake lever).

[0002]

2. Description of the Related Art At present, many parking brake levers are provided with a push button protruding from the tip of the operation lever as a special operation mechanism for releasing braking. For example, Japanese Utility Model Laid-Open No. 59-018647, "Automobile Parking Brake Apparatus," is a device for improving the pitch between ratchet teeth (locking teeth). There are buttons shown. Braking state B
When the push button is pushed in, the pole is rotated in the direction of releasing from the ratchet teeth via the rod, and the release state D
It moves to. The switching from the braking state B to the release state D using such a push button is the same for a retractable parking brake lever which has been seen recently.

[0003]

The conventional brake lever of the type in which the state changes from the braking state B to the release state D only when the push button is pressed, has a fear that the release state D is unexpectedly brought about unless the push button is pressed. There is no safety. However, if the push button is pressed and released immediately, it returns to the braking state B again. To return from the release state D to the non-braking state A, hold down the push button until the operation lever falls down to some extent. Operability is inconvenient.

In the operation to reach the release state D, the operating lever of the brake lever in the braking state B must be slightly lifted, and the push button must be pressed in a state where the engagement between the pawl and the ratchet teeth is loosened. . This means that the driver cannot be brought into the release state D unless the two operations of raising the operation lever and pressing the push button are properly performed in the procedure of raising and pressing. Actually, since the above-mentioned procedure is performed almost simultaneously, the presence of the push button causes a problem that the brake lever cannot be released well for a person who does not drive much or an elderly person.

[0005] Therefore, in order to eliminate the push button from the brake lever, a new brake lever structure has been studied. Specifically, in the procedure of raising the operating lever from the non-braking state A to the braking state B, raising the operating lever again to the releasing state D, and returning from the releasing state D to the non-braking state A by tilting the operating lever. We considered a structure that could be operated.

[0006]

As a result of the study, a parking brake lever that switches between braking and non-braking by raising and lowering the operating lever is changed from a non-braking state A to a braking state B by raising the operating lever. The operating lever released in B is slightly retracted by the pullback by the braking force to be in the releasable state C, the operating lever is again raised from the releasable state C to the releasing state D, and the operating lever is released from the releasing state D to the non-releasing state. A brake lever operated in a procedure for returning to the braking state A, provided with a turnover spring that urges the pole in the direction of engagement with or release from the ratchet teeth with respect to the pole, and the operation lever released in the braking state B If the turnover spring falls slightly due to the pull back by the braking force, the turnover spring changes its posture from the initial state and A parking brake lever to the release state C to urge the Le in the releasing direction from the ratchet teeth. In the releasable state C according to the present invention, although the pawl is urged in the releasing direction from the ratchet teeth, the pawl and the ratchet teeth are still in a strong engagement state, and the pawl and the ratchet are raised by raising the operation lever. It means the state immediately before the engagement with the teeth is released.

More specifically, first, the bias of the turnover spring is indirectly exerted on the pole.
The operating lever includes a pressing lever, a spring for urging the pawl in the direction of engagement with the ratchet teeth, and a turnover spring provided between the pressing lever and the operating lever. A pole which is attached to a pole rotating shaft via a long hole extending in a substantially tilting direction and maintains engagement with the ratchet teeth when the operation lever released in the braking state B slightly falls back by the pullback by the braking force. Is displaced relative to the operating lever within the range of the long hole, and pushes and rotates the pressing lever, and the thought line connecting the pressing and rotating axis of the pressing lever and the connection point of the turnover spring to the operating lever turns over. Beyond the connection point of the spring to the pressing lever, the turnover spring urges the pawl in the direction of releasing from the ratchet teeth via the pressing lever, and can be released. There is a brake lever as a state C.

More specifically, a ratchet plate fixed to a vehicle body, an operation lever having an operation tilting axis on the ratchet plate, a pole mounted on a pole rotation shaft provided on the operation lever through a long hole, and a ratchet A spring for urging the pole against the teeth in the direction of engagement, a pressing lever capable of pressing the pole in the direction of releasing from the ratchet teeth, and an operation lever released in the braking state B slightly fall back by the braking force. And (1) a brake lever configured to change the biasing direction to the release direction and press the pressing lever. In this configuration, the biasing direction of the turnover spring with respect to the pressing lever is changed. The idea line (operation idea line) that separates the biasing direction of the turnover spring is a line that connects the pressing rotation axis of the pressing lever and the connection point (operation connection point) of the turnover spring to the operation lever.

The above detailed (1) brake lever operates in the following procedure. In the non-braking state A, the operating lever tilts until it is regulated (the amount of tilting of the operating lever is normally regulated by a stopper or the like), and (i) the operating lever is raised from the non-braking state A, and In the braking state B, in which the pole locked on the pole rotation shaft is engaged with the ratchet teeth, (ii) the operating lever released in the braking state B slightly falls back by the braking force and engages with the ratchet teeth. The pole fixed in position is displaced relatively upward so that the operation tilt axis is locked at the lower edge of the long hole, pushes and rotates the pressing lever, and connects the turnover spring to the connecting point (press connecting (Point) exceeds the operation concept line, and the turnover spring pushes the pressing lever in the releasing direction of the pawl with respect to the ratchet teeth so that the engagement between the pawl and the ratchet teeth is maintained, so that the releasing state C is reached. When the bar is raised, the engagement between the pawl and the ratchet teeth is weakened, and the pressing of the pressing lever prevails, and the pawl enters a released state D in which the pawl is separated from the ratchet teeth. When returning to the state A, the pressing lever is pressed by the ratchet plate, the pressing connecting point exceeds the operation plan line, the biasing direction of the turnover spring is removed from the releasing direction of the pole, and the pole operates autonomously by the action of the spring. It is pushed down and locked on the pole rotating shaft again by the upper edge of the long hole. In this configuration, since the pawl is separately biased by a spring in the engagement direction, it is not necessary to turn the turnover spring in the engagement direction when the bias of the turnover spring is changed from the release direction.

[0010] Next, to directly apply the bias of the turnover spring to the pole, (2) a turnover spring provided between the operation lever and the pole is provided, and the pole is substantially tilted in the tilting direction of the operation lever. When the operating lever released in the braking state B falls slightly due to the retraction by the braking force, the pawl maintaining the engagement with the ratchet teeth is attached to the pole rotating shaft through the elongated hole extending through the elongated hole. Relative to the operating lever within the range, the connecting point of the turnover spring to the pole exceeds the thought line connecting the pole rotation axis and the connecting point of the turnover spring to the operating lever, and the turnover spring is There is a brake lever which urges in a release direction from the ratchet teeth to be in a releaseable state C.

More specifically, a ratchet plate fixed to a vehicle body, an operation lever having an operation tilting axis on the ratchet plate, a pole mounted on a pole rotation shaft provided on the operation lever through an elongated hole, and a brake Up to the state, the pole is urged in the engaging direction with respect to the ratchet teeth, and when the operation lever is slightly tilted in the braking state, a turnover spring that changes the bias to the releasing direction with respect to the ratchet teeth, and when returning to the non-braking state (2) A brake lever having a configuration comprising a guide rail on which the pawl slides. In this configuration, the biasing direction of the turnover spring with respect to the pole is changed. The idea line (operation idea line) that separates the biasing direction of the turnover spring is a line that connects the pole rotation axis and the connection point (operation connection point) of the turnover spring to the operation lever.

The detailed (2) brake lever operates in the following procedure. In the non-braking state A, the operating lever tilts until it is regulated (the amount of tilting of the operating lever is normally regulated by a stopper or the like), and (i) the operating lever is raised from the non-braking state A, and In the braking state B, in which the pole locked on the pole rotation shaft is engaged with the ratchet teeth, (ii) the operating lever released in the braking state B slightly falls back by the braking force and engages with the ratchet teeth. The pole fixed in position is displaced relatively upward so that it is locked to the pole rotation axis at the lower edge of the long hole, and the connection point (pole connection point) of the turnover spring to the pole exceeds the operation plan line. ,
The turnover spring urges the pole in the release direction with respect to the ratchet teeth to the extent that the engagement between the pawl and the ratchet teeth is maintained, so that the pawl can be released. (Iii) When the operating lever is again raised, the pawl and the ratchet teeth are disengaged. The engagement is weakened, the bias is overcome, and the pole enters the release state D in which the pole is separated from the ratchet teeth. (Iv) When the operating lever is tilted down in the release state D to return to the non-braking state A, the pole follows the guide rail. When the posture is changed, the pole connection point exceeds the operation plan line, the biasing direction of the turnover spring is returned to the engaging direction of the pole, and the pole is again engaged with the pole rotating shaft by the upper edge of the long hole. It is relatively displaced downward so as to stop, and is again locked on the pole rotating shaft by the upper edge of the long hole.

In the brake lever of the present invention, the releasable state C is realized using a slight tilt of the operation lever due to the retraction of the braking force without using a special release mechanism (push button or the like). Since such a retraction of the braking force can be seen in any braking mechanism, the present invention relates to a retractable parking brake lever (an operation lever for connecting a brake cable and an operation lever dedicated to operation are connected in a bending relationship). Brake lever). In this case, if the configuration of the present invention is realized in the operation lever, a configuration for tilting the operation lever can be provided independently.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are partially cutaway side views showing the operation procedure of the above-mentioned (1) parking brake lever of the present invention. FIG. 1 is a non-braking state A (initial state), and FIG. , FIG. 3 shows a releasable state C,
FIG. 4 shows the release state D, and FIG. 5 shows the state immediately before the non-braking state A.

A basic brake lever according to the present invention switches between braking and non-braking by raising and lowering an operating lever 2 connected to a brake cable 1 (represented by a center line, the same applies hereinafter). A series of operations from the non-braking state A to the non-braking state A via the braking state B is the same as the conventional operation, but a slight operation by pulling back the braking force without operating a special release mechanism such as a push button. It is characterized in that a state in which the engagement between the pawl 3 and the ratchet teeth 4 can be released by the lever 2 falling down, that is, a releasable state C is created. Thus, the brake lever of the present invention has the appearance of a single lever without a push button for performing the releasing operation.

As shown in FIG. 1, the brake lever ((1)) of this embodiment has a ratchet plate 5 fixed to the vehicle body.
And an operating lever 2 having an operating tilting shaft 6 on a ratchet plate 5, a pole 3 mounted on a pole rotating shaft 7 of the operating lever 2 through an elongated hole 21, and engaging the pawl 3 with ratchet teeth 4. And a pressing lever 9 capable of pressing the pawl 3 in a releasing direction from the ratchet teeth 4.
And a turnover spring 10 for urging the pressing lever by changing the urging direction to the releasing direction when the operating lever 2 released in the braking state B slightly falls due to the retraction by the braking force. In addition, in an actual product, a stopper for restricting the tilt of the operation lever 2 in the non-braking state A is provided.

The ratchet plate 5 has a pole 3
And the pressing lever 9 whose posture has been changed above the ratchet teeth 4 when returning to the non-braking state A.
push. The support portion 11 is fixed to the vehicle body by, for example, bolting. In this example, a switch that is pressed in the non-braking state A and is released by the rotation of the operation lever 2 in order to further display on the operation panel whether or not the braking state B is present.
12 is attached to the ratchet plate 5.

The operation lever 2 is pivotally mounted on an operation tilting shaft 6 provided behind the ratchet plate 5, and the brake cable 1
Are linked. By raising the operation lever 2 (see the arrow in FIG. 2), the brake cable 1 is pulled to perform braking. In addition, the operating lever 2 is provided with a pressing projection 13 for the switch 12, a pole rotating shaft 7 on which the pawl 3 is mounted, and a pressing rotating shaft 14 of the pressing lever 9. Further, a pole receiving portion 15 for regulating the amount of rotation of the pole 3 when biased in the release direction is formed. The pressing lever 9 has a return portion 16 at the upper end inscribed in the upper edge of the operating lever 2 and can be displaced following the operating lever 2. A pole pressing portion 17 is provided at the lower end of the pressing lever 9, and a pressing connection point 18 with the turnover spring 10 is provided near the pole pressing portion 17.

The turnover spring 10 which is a feature of the present invention is provided between an operation connection point 19 on the lower edge of the operation lever 2 and a pressing connection point 18 of the pressing lever 9. In the non-braking state A, the pressing connection point 18 is located, for example, to the right in FIG. 1 with respect to the operation design line 20, and the pressing lever 9 is urged away from the pawl 3. However, when the operating lever 2 released in the braking state B slightly falls due to the retraction by the braking force (see FIG. 3), the pole 3 is engaged with the ratchet teeth 4 and is fixed in position. Displaced relatively upward so as to lock the pole rotating shaft 7 at the lower edge of the hole 21 and push and rotate the rotation arousing arm 22 of the pressing lever 9 so that the operation design line 20 exceeds the pressing connecting point 18 As a result, the urging direction of the pressing lever 9 switches to the releasing direction of the pawl 3. When the urging direction returns to the non-braking state A, the return portion 16 of the pressing lever 9 is switched by being pushed by the front edge of the ratchet plate 5 and the pressing connecting point 18 straddling the operation design line 20 again. The lever 9 is urged in a direction different from the release direction of the pawl 3 (in this example, substantially coincides with the engaging direction, but the pressing lever 9 itself is separated from the pawl 3).

Next, the operation procedure will be described with reference to FIGS. In the non-braking state A, as shown in FIG. 1, the operation lever 2 is in a state of being tilted until regulated by a stopper or the like. In this non-braking state A, the pole 3 is apart from the ratchet teeth 4. Further, the pressing lever 9 is urged by the turnover spring 10 in a direction in which the pole pressing portion 17 does not press the pawl 3, the return portion 16 is regulated by the upper edge of the operating lever 2, and the rotation provoking arm 22 is particularly Is not pressed (in FIG. 1, the pivoting arm 22 is the pole 3
Appears to be in contact with
It is preferable that there is a gap). In the non-braking state A, since the pressing protrusion 13 of the operation lever 2 presses the switch 12, there is no lighting of a lamp or the like indicating the braking state B in the driver's seat.

When the operation lever 2 is lifted from the non-braking state A by hand, as shown in FIG.
Is caused around the operation tilt axis 6. Then, when the pressing protrusion 13 is separated from the switch 12, a lamp indicating the braking state B is lit on the driver's seat. When the operating lever 2 is further raised, the pole rotating shaft 7 approaches the ratchet teeth 4, and the pawl 3 urged by the spring 8 starts engaging with the ratchet teeth 4. Adjustment of the positional relationship between the components and the length of the brake cable so as to obtain a necessary and sufficient braking force is the same as in the prior art.

When the hand is released from the operating lever 2 in the braking state B, as shown in FIG. 3, the operating lever 2 is pulled within the play allowable in design due to the pulling of the brake cable 1 caused by the braking force and the like. Fall slightly. This operation lever 2
, The pole 3 engaged with the ratchet teeth 4 is relatively displaced upward so as to lock the pole rotating shaft 7 at the lower edge of the long hole 21, and the operation plan line 20 of the turnover spring 10 is moved. As a result of exceeding the pressing connection point 18, the urging direction of the pressing lever 9 changes to the releasing direction of the pawl 3,
Begins to push pole 3. However, since the pressure by the pressing lever 9 is lower than the engagement between the pawl 3 and the ratchet teeth 4, the braking state B is not released, and the state becomes the releasing state D when the engagement is weakened (can be released. State C). As described above, since the engagement between the pawl 3 and the ratchet teeth 4 exceeds the biasing force of the turnover spring 10, the safety for preventing the release of the braking state B without re-initiating the operation lever 2 is assured. Is secured.

When the operating lever 2 is raised again, the engagement between the pawl 3 and the ratchet teeth 4 is weakened. As a result, the pressing of the pawl 3 by the pressing lever 9 is superior, and the pawl 3 is released from the ratchet teeth 4. Actually, the engagement between the pawl 3 and the ratchet teeth 4 is tight, so that the operation lever 2 is slightly increased, and as shown in FIG.
When the force is applied in the direction that causes the state, the state becomes the release state D. When the operation lever 2 is released from here, the operation lever 2 starts to tilt by pulling the brake cable 1 and returns to the non-braking state A (FIG. 1). At this stage, the pressing lever 9 is rotated by the bias of the turnover spring 10, and the return portion 16 is separated from the upper edge of the operation lever 2.

While the operating lever 2 is tilted from the release state D, the pressing lever 9 keeps pressing the pawl 3 in the releasing direction, and the biasing direction of the turnover spring 10 does not change. However, when approaching the non-braking state A, as shown in FIG. 5, the return portion 16 of the pressing lever 9 is pushed by the front edge of the ratchet plate 5 in a direction opposite to the biasing direction of the turnover spring 10. Then, the pressing lever 9 rotates.
As a result, the pressing connection point 18 again exceeds the operation plan line 20,
The biasing direction of the pressing lever 9 by the turnover spring 10 is switched. Then, the pressing lever 9 rotates until it is regulated by the upper edge of the operation lever 2 and is in the initial state (see FIG. 1).
And the operating lever 2 is tilted until it is regulated.

6 to 10 are partially cutaway side views showing an operation procedure of a parking brake lever ((2)) according to another embodiment of the present invention. FIG. 6 shows a non-braking state A (initial state). ),
7 shows the braking state B, FIG. 8 shows the releasing state C, FIG. 9 shows the releasing state D, and FIG. 10 shows the state immediately before the non-braking state A. The brake lever of this embodiment has the same basic configuration as that of the above-described brake lever (FIGS. 1 to 5) except that the pole 3 is directly urged by a turnover spring 10. The following description focuses on the differences.

The brake lever ((2)) of this embodiment includes a ratchet plate 5 fixed to the vehicle body, an operation lever 2 having an operation tilting shaft 6 on the ratchet plate 5, and a pole rotation shaft 7 of the operation lever 2. The pole 3 attached through the slot 21 and the ratchet tooth 4 until the braking state is reached.
Is turned in the engaging direction, and when the operating lever 2 is slightly tilted in the braking state, the turnover spring 10 that changes the biasing to the releasing direction with respect to the ratchet teeth 4 is brought into sliding contact with the pawl 3 when returning to the non-braking state. It consists of a guide rail 23. Also in this example, a stopper for restricting the tilt of the operation lever 2 is provided.

From the non-braking state A (FIG. 6) to the braking state B (FIG. 7)
Is the same as the above example. The pole connection point 24 is beyond the operation plan line 20, and the pole 3 is urged toward the ratchet tooth 4 in the engagement direction. However, braking state B
When the operator releases his / her hand from the operation lever 2, as shown in FIG. 8, the released operation lever 2 slightly falls due to being pulled back by the braking force. As a result, the pole 3 is relatively displaced upward so as to lock the pole rotating shaft 7 at the lower edge of the long hole 21, and the pole connecting point 24 exceeds the operation plan line 20. Is biased in the release direction. In the releasable state C, since the engagement between the pawl 3 and the ratchet teeth 4 exceeds the bias by the turnover spring 10, the braking state B is not released, and the unexpected release of the braking state B is prevented. Safety is ensured.

When the operating lever 2 is raised again, the engagement between the pawl 3 and the ratchet teeth 4 is weakened. As a result, the bias of the pawl 3 by the turnover spring 10 is superior, and the pawl 3 is released from the ratchet teeth 4. Actually, since the engagement between the pawl 3 and the ratchet teeth 4 is tight, the operation lever 2 is slightly raised, and a force is applied in a direction to cause the operation lever 2 as shown in FIG. If you loosen the operation lever 2 from here,
The operation lever 2 starts to tilt due to the tension of the brake cable 1, and returns to the non-braking state A (FIG. 5).

While the operating lever 2 is tilted from the release state D, the biasing direction of the turnover spring 10 does not change, and the pawl 3 remains biased in the releasing direction. However, when approaching the non-braking state A, as shown in FIG. 10, the sliding portion 25 of the pole 3 slides on the guide rail 23 of the ratchet plate 5 and the pole 3 changes its posture. As a result, the biasing direction of the pole 3 by the turnover spring 10 is changed, and the pole 3 is again biased in the engaging direction. Then, the operation lever 2 is tilted until it is regulated, and returns to the non-braking state A.

[0030]

According to the present invention, switching between braking and release can be realized by only raising and lowering the operation lever of the parking brake lever. Moreover, there is no special operation for setting the release state C, and the operation of simply releasing the lever (falling slightly within the permissible range of play) and pulling up the operation lever quickly allows the braking and the release to be performed. Switching is possible. As described above, the brake lever of the present invention is a brake lever that does not have a push button for releasing the brake in appearance, and can provide a simple operation mode for switching between the braking and the release by simply raising and lowering the operation lever. Become.

The provision of a special operation mechanism (push button or the like) for performing the release operation reduces the number of components in the brake lever, improves the assemblability, and contributes to the reduction in manufacturing cost. The present invention has the effect of simplifying the appearance and operability while achieving such convenience, and further realizing cost reduction.
