Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a footrest device for a vehicle on which an occupant sitting on a seat rests his / her foot.

[Conventional technology]

It is well known in the art to provide a footrest device in a vehicle compartment so that an occupant can take a comfortable posture. Such a foot rest device is roughly classified into two types, one is a leg rest on which an occupant's leg is placed, and the other is a foot portion below the ankle, that is, a foot rest.

[Problems to be solved by the device]

Conventionally, the legrest and the footrest are separately configured, and these are assembled at predetermined positions in the vehicle compartment when the vehicle is manufactured. As a result, the leg rest and the foot rest are bulky, and the work of assembling them into the vehicle body is very complicated.

In addition, since the conventional footrest has a constant posture when used, the position at which the occupant places his / her foot on the footrest is always unchanged. However, the occupant's physique and preferences for stretching the legs are not constant, and the most preferable position at which the occupant places his / her foot on the footrest usually varies depending on the occupant. Therefore, the conventional footrest cannot give the best feeling of rest to all the occupants, and it is inevitable that the footrest is slightly unusable.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks and provide a footrest device for a vehicle in which a legrest and a footrest are integrally configured.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a main link pivotally supported by a vehicle body between a storage position and a use position,
A legrest supported by the main link, a footrest rotatably supported by the main link between a storage position and a use position, and a rotation range of the footrest with respect to the main link are adjusted. A footrest device for a vehicle is proposed, which comprises a footrest rotation range adjusting means for changing the use position of the vehicle.

At that time, it is advantageous to provide a spring for urging the main link toward the storage device and a spring force adjusting means for adjusting the urging force of the spring.

It is rotatably supported. On the other hand, the left support pin 7 is rotatable with respect to the base bracket 6,
However, it is fitted so as not to rotate relative to the main link 8, and the central slit 34 formed in the support pin 7 is
The center end 36 of the spiral spring 35 is engaged with the outer end 37 of the spiral spring 35, and the outer end 37 of the spiral spring 35 is locked to the base bracket 6 side as described later in detail. No spiral spring is attached to the right base bracket 6.

The spiral spring 35 described above constitutes an example of a spring that biases the main link 8 toward the storage device shown in FIG.

In addition, leaf springs are placed near the long holes 13, 13a of each main link 8, 8a.
38 and 38a are fixed.

The operation of the footrest device 1 configured as described above is as follows.

When the footrest device 1 is not used, the respective elements are stored in the space below the cabinet 5 in a folded state as shown in FIG. At this time, the striker 39 (see also FIG. 3) fixed to the core member 21 of the footrest 20 engages with the locking groove 41 of the hook 40 rotatably supported by the bottom plate of the cabinet 5 via the pin 42. The footrest device 1
Is stored and held in the state shown in FIG.

The hook 40 is given a turning tendency around the pin 42 in the clockwise direction in FIG. 4 by a torsion coil spring (not shown), and a hook (not shown) causes the hook 40 to rotate in a clockwise direction more than the position shown in FIG. It is prevented from rotating in the direction. This hook 40 also has a tube 43
One end of a wire 44 slidably inserted in the wire 44 is locked, the wire 44 extends to an operation lever 45 rotatably supported by the cabinet 5, and the other end of the wire 44 is locked by the lever 45. ing.

When using the footrest device 1, the rear seat 3 (first
An occupant seated on the drawing pulls the operation lever 41 in the direction of arrow C. This pulls the wire 44 in the direction of the arrow D, and the hook
40 rotates counterclockwise around the pin 42 against the spring force and the striker 39 disengages from the hook 40. Therefore, the footrest device 1 is rotated clockwise by its own weight in FIG. More specifically, Spiral Spring 35
The main links 8, 8a integrated by the connecting rod 14 rotate clockwise around the axis of the support pins 7, 7a from the storage device against the urging force of. Main link at this time
Between the 8 and 8a and the support plates 22 and 22a, the washer as described above is used.
Since a predetermined frictional force is applied by 25, 25a, 26, 26a, both support plates 22, 22a and the footrests fixed to them
20 rotates together with the main links 8 and 8a. That is, the footrest 20 rotates with respect to the main links 8 and 8a while being stored in the storage device. Also regulated links 10,10a
Also pivots clockwise about the pivot pin 9, 9a, but the pivot pin 9, 9a, which is the pivot center, and the support pin 7, 7a, which is the pivot center of the main links 8, 8a, move vertically. Since the positions are deviated, the guide rollers 12, 12a located on the tip side of the restriction links 10, 10a move upward in the elongated holes 13, 13a together with the slide pins 11, 11a.

As described above, when each element rotates clockwise due to its own weight,
Since the support pin 7 to which the outer end 37 of the spiral spring 35 is locked also rotates together with the main link 8, the spiral spring 35 is deformed so that its diameter is reduced, that is, the spring force is strengthened. Then, as shown in FIG. 5, when the slide pins 11, 11a come close to the free ends of the leaf springs 38, 38a, the weight of the footrest device 1 and the spring force of the spiral spring 35, that is, the main link. 8,8a
Is just balanced with the urging force that tries to return it to the storage device, and the footrest device 1 stops in the state shown in FIG. In this way, the footrest device 1 is rotated while applying its own weight and the spring force of the spiral spring 35, so that it can be operated quietly and smoothly.

Next, the occupant places his foot or hand on the tip of the footrest 20 and pushes it down. Then, first, the main link 8,8a
The footrest 20 and the footrest 20 rotate slightly clockwise together, and the slide pins 11 and 11a come into contact with the free ends of the leaf springs 38 and 38a. Push down the footrest 20 further and slide 1
1,11a tries to get over the free ends of the leaf springs 38,38a, but the main link 8,8a and the support plate are stronger than the force required for this.
Since the spring constant of the leaf springs 38, 38a and the frictional force are set so that the above-mentioned frictional force acting between the leaf springs 38, 22, 22a becomes smaller, The support plates 22 and 22a and the footrest 20 rotate clockwise around the pins 23 and 23a with respect to the main links 8 and 8a without overcoming the free end of the 38a. At this time, the sliders 32, 32a, which are integrated with the footrest 20, are replaced by the main links 8, 8a.
It moves downward while sliding in the guide holes 33, 33a. Then, as shown in FIG. 6, the sliders 32, 32a are inserted into the guide holes 33, 3
The support plates 22 and 22a and the footrest 20 stop rotating with respect to the main links 8 and 8a when they hit the lower end of 3a. The position of the footrest 20 at this time is its use position.

When the footrest 20 is further pressed in the above-mentioned state, the main links 8 and 8a rotate together with the footrest 20 around the support pins 7 and 7a in a slightly clockwise direction, and the slide pins 11 and 11a at the upper ends of the restriction links 10 and 10a move. While overcoming the free ends of the leaf springs 38, 38a while elastically deforming them, the leaf springs 38, 38a and the slide pins 11, 11a engage with each other as shown in FIG.
The pins 11 and 11a (to be exact, the guide rollers 12 and 12a) have the long holes 1
The ends of the 3,13a come into contact with each other, and the main links 8,8a stop at their use positions.

A force toward the storage device shown in FIG. 4 acts on the main links 8 and 8a by the spiral spring 35. However, by engaging the slide pins 11 and 11a with the leaf springs 38 and 38a as described above, The main links 8 and 8a can be locked in their use positions. Without leaf springs 38 and 38a,
The main links 8 and 8a may move up and down due to the action of the spiral spring 35 and its own weight.
By pressing the slide pins 11, 11a by the 8, 38a, the occurrence of such a problem is prevented.

As described above, the footrest 20 is fixedly fixed in the use position as shown by the solid line in FIG.
Place your foot on the footrest 20
You can put it on and take a comfortable posture.

Further, when the main links 8 and 8a are brought to their use positions as described above, the leg rest 15 occupies the position shown by the solid line (or broken line) in FIGS.
It is held in this position by the first stoppers 46, 46a protruding from the 8, 8a. The occupant should keep the leg rest 15 in this state.
In addition, the feet can be placed as shown by the solid line in FIG. Alternatively, the leg rest 15 is rotated clockwise around the pins 19 and 19a, and the main links 8 and 8a are rotated.
The second stoppers 47, 47a projecting from the above can be held at the position shown by the chain double-dashed line in FIGS. 1 and 6 and the legs can be placed on it to assume a comfortable posture.

In addition to the proper number of washers, a wave washer 48 (Fig. 3) is fitted between the pins 19 and 19a and the mounting brackets 18 and 18a, so that the leg rest 15 is rattled when the vehicle is running. Can be prevented.

When retracting the footrest device 1, first, the leg rest
Fold 15 to the position shown by the solid line in FIG. 6 and then rotate the footrest 20 counterclockwise to raise it. At this time, since the engaging force between the slide pins 11 and 11a and the leaf springs 38 and 38a is larger than the frictional force acting between the main links 8 and 8a and the supporting plates 22 and 22a, they are engaged. As it is, that is, with the main links 8 and 8a held in the use position shown in FIG. 6, only the support plates 22 and 22a and the footrest 20 rotate counterclockwise with respect to the main links 8 and 8a. Then, as shown in FIG. 7, the main links 8 and 8a and the support plates 22 and 22a are
The footrest 20 stops when the stop claws 49, 49a; 50, 50a protruding from each other come into contact with each other. That is, when the footrest 20 is stored in the storage device, the footrest 20 stops with respect to the main links 8 and 8a. When the footrest 20 is further lifted, the main links 8 and 8a rotate together with the footrest 20 around the support pins 7 and 7a in the counterclockwise direction in FIG. Rotate counterclockwise around to disengage the slide pins 11 and 11a from the leaf springs 38 and 38a,
Finally, the main links 8 and 8a rotate to the storage position shown in FIG. At this time, striker 39 of footrest 20
Rotates the hook 40 slightly in the counterclockwise direction and then engages with the hook 40, and the entire footrest device 1 is stored in the position shown in FIG.

In the footrest device 1 illustrated above, the footrest 20 and the legrest 15 are integrally assembled, and the whole of the footrest device 1 forms one unit. Can be easily assembled to the vehicle body.

By the way, as described above, if the use position of the footrest 20 is always constant, the usability becomes poor. Therefore, in the footrest device 1 illustrated, the footrest 20
It is configured such that the use position of can be switched from the position shown by the solid line in FIGS. 1 and 6 to the position shown by the alternate long and short dash line. Specifically, as described above, two supporting plates 22, 22a, that is, first and second positioning holes 27, 27a, 28, 28a, respectively, are formed, and adjusting screws 29, 29a is selectively inserted.

In order to switch the use position of the footrest 20, the knob portion 52 of the adjusting screw 29 shown in FIG. 8 is grasped and the screw 29 is turned, and the screw portion 53 of the screw is engaged with the screw member 31. , The adjusting screw 29 is moved to the right in the figure as shown in FIG. When the adjusting screw 29 is rotated, the guide hole 33
The non-rotatably fitted slider 32 and the non-rotatable female screw member 31 do not rotate together.
29 can be surely moved in the direction of coming out of the female screw member 31. As a result, the large diameter boss portion 30 of the adjusting screw 29 is disengaged from the first positioning hole 27, and the small diameter screw portion 53 is positioned in the hole 27. At this time, the pin 55 protruding from the screw portion 53 hits the female screw member 31, and the adjusting screw 29 is pushed by the female screw member 31.
It does not come off. Next, the adjusting screw 29 is lowered downward together with the female screw member 31, the slider 32, the E ring 51 and the like,
The small-diameter screw portion 53 is passed through the narrow transition portion 54 between the first and second positioning holes 27 and 28 and moved to the second positioning hole 28 side. Next, the knob portion 52 is rotated, and the screw portion 53 is screwed into the female screw member 31 again and tightened, and the boss portion 30 is fitted into the second positioning hole 28 without rattling, and the adjusting screw 29
Is fixed to the female screw member 31.

The same operation is performed on the adjustment screw 29a on the right side.

As described above, with the adjusting screws 29, 29a fitted in the second positioning holes 28, 28a, the main link 8,
8a and the footrest 20 are brought into the use position, the sliders 32, 32a stop by hitting the lower ends of the guide holes 33, 33a as shown in FIG. 2 Since it is fitted in the positioning holes 28, 28a, both positioning holes
28, 28a; 27, 27a, that is, the angle θ (FIG. 3) about the threaded pins 23, 23a,
The support plates 22 and 22a and the footrest 20 stop at the use position shown by the alternate long and short dash line above the use position shown by the solid line in FIGS. 1 and 6. Therefore, the occupant can put his / her foot on the footrest 20 located at a slightly higher position as shown by the alternate long and short dash line in FIG.

By fitting the adjusting screws 29, 29a into the first positioning holes 27, 27a again, the footrest 20 can be held in the use position shown by the solid line in FIGS. 1 and 6. In this way, the occupant can switch the use position of the footrest 20 according to his / her physical condition and taste, and can put his / her foot on the footrest 20 in the most comfortable posture.

In addition, the adjusting screw 29, 29a is set to one of the positioning holes 27, 27a; 28,
Even when fitted to 28a, when the footrest 20 is rotated upward as shown in FIG. 7 to store the footrest device 1, the stop claws 49, 49a and 50, 50a come into contact with each other. Since the footrest 20 stops against the main links 8 and 8a,
The stop position is always constant. Therefore, when the entire footrest device 1 is stored as shown in FIG. 4, the relative position of the footrest 20 with respect to the hook 40 is always constant, and the hook 40
The footrest 20 can be reliably locked by the.

In the above embodiment, two positioning holes are formed in each of the support plates 22 and 22a, but three or more positioning holes are provided to adjust these adjusting screws.
29 may be selectively fitted, and the use position of the footrest 20 may be switched in three or more steps.

As can be seen from the above description, in this example, the positioning holes 27, 27
The a, 28, 29a and the adjusting screws 29, 29a constitute a turning range adjusting means for adjusting the turning range of the footrest with respect to the main link and changing the use position of the footrest.

By the way, as described above, since the main links 8 and 8a are biased toward the retracted position by the spiral spring 35, the footrest device 1 can be gently rotated from the retracted state by its balance with its own weight. When the footrest device 1 is stowed from the state shown in FIG. 7,
It can be rotated easily with the help of spring force. However, the spring force of the spiral spring 35 and the self-weight of the footrest device 1 usually vary in size due to variations in manufacturing and assembly. At that time, if the spring force becomes too large or too small compared to its own weight, not only the operability deteriorates, but also when the footrest device 1 is operated from the state of FIG. 4 to the position of FIG. , The slide pins 11 and 11a stop at the front side more than the predetermined position, and conversely the pins 11 and 11a are leaf springs.
It may hit the 38, 38a hard and generate abnormal noise. Therefore, in this example, a spring force adjusting means for adjusting the urging force of the spiral spring illustrated in FIG. 10 and FIG. 11 is additionally provided, and is configured so that the self-weight and the spring force described above can be balanced. There is.

In FIGS. 10 and 11, the support pin 7 (not shown in FIG. 10) is attached to the base bracket 6 as described above, but an arcuate hole 56 centered on the axis of the pin 7 is formed. The spring locking member 58 is fixed by a screw 57 formed in the base bracket 6 and inserted through the hole 56 (the holes 56 and the screw 57 are not shown in FIGS. 4 to 7). ). Loosen the screw 57 to open the locking member 58.
Can be moved along 56.

As described above, the center end of the spiral spring 35
36 is locked in the slit 34 of the support pin 7, but its outer end 37 is locked in the spring locking member 58 as shown in FIG. In this way, the outer end 37 is locked to the base bracket 6 side.

On the other hand, the base bracket 6 is provided with a screw hole 59 in which a female screw is formed, and a fine adjustment screw 60 is screwed into the screw hole 59, the tip of which is in contact with the spring locking member 58, and
The screw 60 is fixed to the base bracket 6 by tightening lock nuts 61 and 62 screwed onto the screw 60. The fine adjustment screw 60 extends through a through hole (not shown) formed in the partition wall 2 shown in FIG.

When adjusting the spring force of the spiral spring 35, loosen the lock nuts 61 and 62 and the screw 57,
1 As shown in the figure, screwdriver 6
3 is engaged, and the fine adjustment screw 60 is rotated while the locking member 58 is pressed against the tip of the screw 60. By this, the locking member 58
Moves with the outer end 37 of the spiral spring 35 in the direction indicated by the arrow P or Q in FIG. If you move it in the P direction, the spring force of the spiral spring 35 will increase, and conversely Q
If you move it in the direction, the spring force will weaken. In this way, the spring force of the spiral spring 35 is set to a value that is well balanced with the weight of the footrest device 1, and then the screw 57 and the lock nuts 61 and 62 are tightened to make the spiral spring 35 against the base bracket 6. Fix the position of the outer end 37 of the.
In this way, the spring force of the spiral spring 35 can be adjusted and the footrest device 1 can be operated in an optimum state by a simple operation.
