Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile roof carrier for loading a load such as a ski or a snowboard on an automobile roof.

[0002]

2. Description of the Related Art An example of a roof carrier for an automobile is disclosed in Japanese Patent Application Laid-Open No. 3-262748. This is such that a clamp device (loading means) for holding a ski plate is fixed to both ends of a beam extending in a vehicle width direction on a roof with screws. In this clamp device, a support base which is raised by being connected to a beam, and a clamp rotatably supported on an upper end of the base are provided. Each is sandwiched by two sheets from the left and right.

[0003]

In the above-mentioned roof carrier, since the loading means is fixed on the roof, it is necessary to extend a hand on the roof to load and unload the luggage. There is a problem, especially for cars with a high vehicle height.

[0004] On the other hand, the present applicant first supports the loading means on a support member on the roof by a parallel link mechanism, so that the loading means is positioned above the roof and at a vehicle body side position lower than the roof. (Japanese Patent Application Nos. Hei 8-201407 and Hei 9-5)
No. 2764). According to this, when the loading means is lowered from the roof to the vehicle body side position,
Removal work can be performed.

[0005] However, if the loading means is installed upright above the roof, the vehicle height will increase accordingly, and it will not be possible to use the vehicle if the vehicle height is limited in a parking lot or the like. Therefore, in consideration of this point, it is preferable that the loading means can be supported on the roof in such a state that the loading means is laid down as much as possible. However, in this case, there are the following problems.

In other words, if the loading means has a supporting posture that stands substantially upright on the roof, the parallel link is set to an upright position along the loading means on the roof, so that the loading means is attached to the side of the vehicle body. By applying force to it, it can be lowered with a light force using its own weight. However, in the case where the loading means takes a supporting posture such that it falls down on the roof, the parallel link also takes a posture lying down on the roof. Therefore, in order to lower the loading means from above the roof, it becomes necessary to apply a force for temporarily raising the loading means on the roof. When the skis are not loaded on the loading means, this is not a problem, but when the entirety including the loading means becomes heavy as in the case of loading a lot of skis, a relatively large force is required for the lifting. I need.

[0007]

SUMMARY OF THE INVENTION Accordingly, in the present invention, the above-mentioned link mechanism is used to raise and lower the loading means, and the loading means can be raised and lowered by a predetermined angle on the roof. Is solved.

[0008] The present invention provides a loading means for holding a load,
An automotive roof carrier comprising a bracket for supporting the loading means at an end of a roof of a vehicle body, wherein the loading means is disposed inside and outside in a positional relationship with respect to the vehicle body when the loading means is positioned above the roof, and A pair of links, one end of which is rotatably connected to the loading means and the other end of which is rotatably connected to the bracket, wherein the loading means is positioned above the roof and at a side of the vehicle body lower than the roof. And one of the pair of links is mounted on the bracket so that the loading means stands up and down at a predetermined angle with the loading means positioned above the roof. Alternatively, it is connected to the loading means so as to be relatively movable.

[0009] That is, in the four-bar linkage, one degree of freedom is given to one pair (connection point) so that the loading means can be raised and lowered on the roof. Accordingly, the vehicle height can be reduced by setting the loading means on the roof so that the vehicle height can be lowered, and if the loading means is erected on the roof, the weight of the loading means can be effectively used to generate a relatively light force. Can be lowered to the side of the vehicle. No significant required force is required to raise the loading means on the roof.

[0010] Any of the four connecting points at both ends of the two links may be configured to be relatively movable, and the relative movement may be performed by providing a long hole on the link side and loading on the loading means side. The engagement position of the long hole may be shifted with respect to the fixing pin on the bracket side, or a long hole is provided on the loading means side or the bracket side, and the pin on the link side is moved by the long hole. It may be. Further, a long groove may be formed instead of the long hole, and the pin may be engaged with the long groove.

Here, the pair of links have the same length, the outer link of which is rotatably connected to the bracket at one point, and a pin provided on the inner link of the pair of links. When the loading means is positioned at the roof upper position, the outer link is slidably slidable in a long hole formed in the bracket so as to stand up and down at a predetermined angle around the bracket side connection point of the outer link and Preferably, it is rotatably engaged.

In this case, the loading means slides up and down at a predetermined angle about the bracket-side connection point of the outer link as the pin of the inner link slides in the long hole of the bracket.

[0013]

Therefore, according to the first aspect of the present invention, one of the pair of links for moving the loading means between the upper position of the roof and the side position of the vehicle body lower than the roof is replaced with one of the links. The loading means is connected to a bracket or a loading means on the roof so as to be relatively movable so that the loading means stands up and down at a predetermined angle in a state positioned above the roof. The vehicle height can be lowered by supporting it in the lying down position, and by raising it on the roof, the weight of the loading means can be effectively used to lower it to the side of the vehicle with relatively light force. be able to.

According to the second aspect of the present invention, the pair of links have the same length, and the outer link of the links is rotatably connected to the bracket at one point, and A pin provided on the inner link is formed on the bracket such that the loading means is positioned upright on the roof at a predetermined angle around the bracket-side connection point of the outer link. The sliding means is slidably and rotatably engaged with the elongated hole, so that the loading means can be raised and lowered on the roof with a simple configuration in which the elongated hole is formed in the bracket.

As shown in FIG. 8, the slide plate 61 is supported by a connecting plate 68 extending between the front ends of the link bases 42, 42 of the carrier lower 8 so as to be movable back and forth. Further, a tension coil spring 69 is stretched between the hinge pin 51 (for the carrier upper 9) and the slide plate 61 extending between the rear ends of the link bases 42, 42, and the slider 35 is moved by the spring 69. It is biased to move backward. The meaning of this bias will be described later. The connection plate 68 is connected to the first lock member 6.
By contacting the base of the slider 5, it serves as a stopper for preventing the slider 35 from moving more than a certain amount rearward regardless of the bias.

The slide knob 62 has a pair of knobs 71, 71 projecting upward from the left and right front ends thereof, and has a hook-shaped second lock member 72 projecting downward from the lower surface thereof. Both ends of a horizontal pin 74 passing through a long hole 73 in the front-rear direction on the left and right sides of the front end of the carrier lower 8 are coupled to the knobs 71, 71.
2 is supported by the horizontal pin 74 so as to be movable back and forth. Therefore, the slider 35 as a whole is supported by the connecting plate 68 and the horizontal pin 74 so as to be able to move back and forth.

(First Lock Member 65 and Second Lock Member 72) The first lock member 65 is
The loading means 7 is held by the support member 5, that is, held on the roof, by the projection at the front end engaging with the connecting plate 25 b at the rear end from below. On the other hand, the second
The lock member 72 holds the loading means 7 on the support member 5, that is, holds it on the roof by engaging the protrusion at the front end with the connection plate 25 a at the front end of the support bracket 16 from below. The urging by the tension coil spring 69 urges the slider 35 in a direction in which the lock members 65 and 72 engage with the connection plates 25b and 25a. Further, as is clear from the above, the connecting plates 25a, 25a,
25b functions as a lock member that constitutes the lock means.

The positional relationship between the two lock members 65 and 72 will be described. The first lock member 65 and the connecting plate 25b are connected to the support member 5 of the link mechanism 6 when the loading means 7 is held on the roof. Behind the pivot point of
In other words, it is located on the side where the pivot point of the carrier lower 8 exists,
Sway of the loading means around the pivot point on the support member 5 side is prevented. On the other hand, the second lock member 72 and the connection plate 25
In the same state, a is located forward of the pivot point of the link mechanism 6 on the carrier lower 8 side, that is, on the side where the pivot point of the support member 5 exists, and is centered on the pivot point of the carrier lower 8 side. Prevent shaking of the loading means.

When the lower surfaces of the protrusions of the lock members 65 and 72 abut against the connection plates 25b and 25a, the slider 35 is moved rearward against the bias of the tension coil spring 69. Is formed on the inclined surface that guides.

(Elevating / lowering urging means of the loading means 7) A torsion coil spring 75 is fitted to the carrier support pin 32 of the second link 27 of the link mechanism 6. When the loading means 7 is held on the roof, both ends of the torsion coil spring 75 are connected to the connecting plate 29 of the second link 27 and the link bases 42 and 4 of the carrier lower 8.
The loading means 7 is urged to move from the roof to the side of the vehicle body by engaging with the connecting plate 76 extending between the rear ends of the two. The urging force becomes weaker as the loading means 7 moves away from the roof.
As shown in FIG. 0, when the loading means 7 is lowered to some extent, the connection plates 29 at both ends of the torsion coil spring 75,
76 is substantially disengaged and its biasing force is zero.

The connecting bar 34 at the center of the second link 27
And the pivot pin 32 of the first link 26 on the carrier lower 8 side.
And a tension coil spring 77 is stretched. The tension coil spring 77 urges the loading means 7 to rise when the loading means 7 is at the side position of the vehicle body. The urging force becomes weaker as the loading means 7 moves away from the lateral position of the vehicle body.

Accordingly, when the loading means 7 is located on the roof, the urging force of the torsion coil spring 75 is larger than the urging force of the tension coil spring 77, so that the first
When the lock by the lock member 65 and the second lock member 72 is released, the stacking means 7 automatically starts lowering. When the loading means 7 is lowered to some extent, the urging force of the torsion coil spring 75 becomes zero, while the tension coil spring 77
As a result, the loading means 7 does not suddenly descend to the side of the vehicle body, but stops descending halfway.

On the other hand, when the loading means 7 is positioned at the side position of the vehicle body, the upward urging force of the tension coil spring 77 is acting. It will automatically rise to the position you set. To raise the loading means 7 on the roof,
What is necessary is just to push up the torsion coil spring 75 against the bias.

(Holding of Loading Means 7 at Side Position of Car Body) The loading means 7 is provided with the pawl 33 of the first link 26 and the slide plate 6 irrespective of the upward bias by the tension coil spring 77.
By the action of the abutment portion 66 and the engagement portion 67, it is held at the lateral position of the vehicle body. in this case,
A protrusion protruding to both sides is formed at the front of the slide plate 61, and the rear surface of the protrusion is
6 and a front side surface is formed on the engaging portion 67.

That is, when the loading means 7 moves to the side position of the vehicle body, the claw 33 of the second link 26 comes into contact with the abutment portion 66 during the movement. With the rotation of the claw 33, the abutment portion 66 moves the claw 3
3, whereby the slider 35 moves forward against the urging of the tension coil screw 69 as the urging means for locking.

When the loading means 7 moves to the position on the side of the vehicle body, the engagement between the claw 33 and the abutment 66 is released. Thereby, the slider 35 is connected to the tension coil spring 6 for locking.
9 moves backwards. This movement is prevented by the contact when the first lock member 65 hits the connection plate 68 of the link base 42. When the force for pulling the loading means 7 down to the side position of the vehicle body is released, the loading means 7 tends to rise by the urging force of the extension coil spring 77, and as a result, as shown in FIGS. Engages with the engaging portion 67. Due to this engagement, the first link 26 is prevented from rotating in the ascending direction, and the loading means 7 is held at the lateral position of the vehicle body irrespective of the upward bias by the extension coil spring 77. .

(Locking means) As shown in FIG. 8, a stopper member 48 provided at the front end of the carrier lower body 41 is provided with a slide knob 62 for operating the lock of the loading means 7 on the roof and the release thereof. A first stopper portion 81 for preventing movement in the release direction, and a second stopper portion 82 for preventing the lock operation member 56 for operating the lock of the carrier upper 9 with respect to the carrier lower 8 and releasing the lock operation member 56 in the release direction. And

In this embodiment, the moving direction when unlocking the slide knob 62 is forward, and the moving direction when unlocking the lock operating member 56 is rearward. And the rear end face of the lock portion 56a of the lock operation member 56 are arranged vertically. On the other hand, the stopper member 48 is provided between the lower portion of the slide knob 62 and the lock portion 56a of the lock operation member 56.
And is located at an intermediate position. The stopper member 48 has a locking position where the first stopper portion 81 contacts the lower front end surface of the slide knob 62 and the second stopper portion 82 contacts the locking portion rear end surface of the lock operation member 56. The key cylinder 49 is moved in the front-rear direction so that the levers 81 and 82 rotate 90 degrees between a lower front end surface of the slide knob 62 and a release position which does not interfere with the movement of the lock operation member 56 in the release direction. It is supported by the operating shaft.

Therefore, when the key 50 is inserted into the key cylinder 49 and the stopper member 48 is rotated to the above-mentioned locking position, the lock is released by pulling the slide knob 62 and the lock is released by pushing the lock operation member 56. The loading means 7 is blocked by the stoppers 81 and 82 and
And the carrier upper 9 cannot be removed together. Key 5 above
When the stopper member 48 is rotated by 90 degrees by the operation 0, the locked state is released, and the loading means 7 is lowered from the roof by operating the slide knob 62 or the lock operation member 56 and the carrier upper 9 is moved. Opening is possible.

(Relationship Between Tightening Screw 22 of Supporting Member 5 and Link Mechanism 6) Of the two screws for fastening the supporting member 5 to the beam 3 on the roof, the fastening screw 22 on the beam tip side is
The tightening screw 22 and the second link 27 of the link mechanism 6 are viewed through the notch at the center of both plates 25, 25.
When the loading means 7 is held on the roof, the second link 27 is positioned on an extension of the axis of the tightening screw 22, as shown in FIG.

Therefore, when the loading means 7 is lowered from above the roof, the tightening screw 22 is not hidden by the second link 27, so that the tightening and releasing operation can be performed from the notch. However, when the loading means 7 is held on the roof, the fastening screw 22 is hidden by the second link 27, and the release operation cannot be performed by a hexagon wrench or the like.

(Use of Roof Carrier) In order to fix the roof carrier 1 to the beam 3, the protrusions 17 a, 17 a at the one end of the coupling bracket 15 are removed with the clamping screw 21 with the knob at one end removed. On the top,
A hole formed by the projecting portions 17b, 17b at the other end, the connecting plate 19, and the tightening screw 22 is fitted from the end of the beam 3. Then, the both ends are connected to the beam 3 by tightening the beam 3 by narrowing the space between the protrusions 17a, 17a and the protrusions 17b, 17b at both ends by the tightening screws 21 and 22.

In order to load the ski 91 shown in FIG. 13, the lock is released by operating the key 50 and the slide knob 62 is pulled forward. Thereby, the first
The engagement between the lock member 65 and the second lock member 72 and the connection plates 25b and 25a of the support bracket 16 is released.

Therefore, as shown in FIG. 5, if the lower end portion of the loading means 7 is held to cause this, the loading means 7 will be able to move the pivot pin 31 of the second link 27 to the length of the support bracket 16. With the movement of the hole 30 from the lower end to the upper end, the first link 26 is turned upright about the pivot pin 31 of the first link 26 as a fulcrum. When the loading means 7 is erected, if a force is applied to the upper end side of the center of gravity of the loading means 7, it can be erected with a relatively light force by the principle of leverage.

Thereafter, when the loading means 7 is pulled to the side of the vehicle body, the loading means 7 automatically starts descending by the urging of the torsion coil spring 75, and the torsion coil spring 7
The lowering is stopped at a position where the downward urging force of 5 and the upward urging force of the tension coil spring 77 are balanced. Therefore, the loading means 7
Is forcibly lowered to the side of the vehicle body. The raising / lowering operation of the loading means 7 is the same when a ski or the like is loaded, and a large force is not required.

When the loading means 7 is lowered to the side of the vehicle,
The pawl 33 of the first link 26 bites into the engaging portion 67 of the slide plate 61, and the loading means 7 is held at a position on the side of the vehicle body. When the lock operation member 56 of the carrier upper 9 is pressed, the lock portion 56a and the engagement pin 5 of the carrier lower 8 are pressed.
The carrier upper 9 is automatically opened by the urging of the torsion coil spring 52. Then, the positioning member 12 is raised and locked to the protruding member 11, and the protruding member 11 and the positioning member 12 are positioned and the ski 91 is loaded. When the carrier upper 9 is put on, the lock portion 56a of the lock operation member 56 is
9 is engaged. Thus, the ski 91 is sandwiched between the loading surface of the carrier lower 8 and the elastic body 54 of the carrier upper 9. In this case, two roof carriers 1 are arranged at front and rear portions of the roof 2 of the automobile as shown in FIG.

Next, at the side position of the vehicle body, the pawl 33 of the first link 26 and the slide plate 61 are pulled down by slightly lowering the loading means 7 slightly further.
Is released from the engagement with the engagement portion 67 and the slide knob 62 is pulled to avoid the engagement, the loading means 7 is driven by the tension coil spring 77 so that the torsion coil spring 75
Automatically attempts to ascend to a position where it is balanced with the downward biasing force. Therefore, if the loading means 7 is pushed up by using the rising urging force, it can be easily lifted to the roof.

If the loading means 7 is pressed against the support bracket 16 on the roof, the first and second locking members 65 and 72 are engaged with the connecting plates 25b and 25a, and the loading means 7 is mounted on the roof. It will be held on top.
If the lock operation member 56 and the slide knob 62 are locked so as not to be operated by the operation of the stopper member 48 by the key 50, the carrier upper 9 can be opened or the loading means 7 can be lowered. Disappears. When the loading means 7 is held on the roof, the fastening screw 22 is hidden by the second link 27. However, since the loading means 7 cannot be lowered as described above, the fastening screw 22 is The roof carrier 1 cannot be removed from the beam 3 even if it cannot be exposed and the other fastening screw 21 is removed.

While the vehicle is traveling, the traveling vibration is transmitted to the roof carrier 1. However, the loading means 7 is supported by the first lock member 65 and the second lock member 72.
6, the loading means 7 is prevented from swinging around any pivot point of the link mechanism 6.

As shown in FIG. 14, the operation for loading the snowboard 92 is basically the same as that for the ski 91. In this case, since the width is wider than the ski 91, the positioning member 12 is mounted. To be loaded. Therefore, as shown in FIG. 15, the snowboard 92 is placed on the elastic body 45 of the protruding member 11,
1 is formed so as to be elastically immersible, so that when one snowboard 92 is provided, it slightly sinks, and when two snowboards 92 are provided, it sinks further. However, in any case, the elastic reaction force of the projecting member 11 and the elastic body 54 of the carrier upper 9
And it will be held elastically.

In the above embodiment, the carrier upper 9 is pivotally supported on the carrier lower 8. However, the carrier upper 9 may be completely removed from the carrier lower 8.

The body of the carrier lower 8 and the carrier upper 9 is not limited to plastic, but may be made of aluminum or stainless steel.
