Description

The present invention relates to a device for fixing a roof box to a cross bar provided on a roof of a vehicle.

Conventionally, there are many structures for fixing a roof box to a crossbar provided on the roof of the vehicle, but in recent years, the shape and size of the crossbar provided on the roof of the vehicle, which is to be fixed to the roof box, are different. There is a tendency to diversify, and compatibility (general versatility) with various types of crossbars is required.

In addition, the increase in the number of roof boxes with large luggage storage capacity in the left-right direction (the same direction as the left-right direction of the vehicle) and the increase in vehicles with high vehicle height due to the increase in minivan type vehicles The fixing work is difficult.

As shown in FIG. 14, a conventional structure for fixing a roof box to a general crossbar is a substantially U-shaped arm member 140 having a contact portion with the lower surface of the crossbar 2 and having screw portions at both ends. And a hole provided in the roof box bottom 1 through which the arm member 140 can be inserted, and nuts 141 for tightening screw portions provided at both ends of the arm member.

However, in the above-described prior art, the roof box 1 is fixed by lifting the arm member 140 from below the bottom of the roof box at a position where the substantially central portion of the arm member 140 and the lower surface of the crossbar 2 can be in contact with each other. It is necessary to fasten and fix the threaded portion from the inside of the roof box 1 with the nut 141 while maintaining the state where the threaded portion is projected from the hole provided at the bottom of the roof box to the inner surface of the roof box 1. Usually, the roof box 1 is fixed to the crossbar 2 at four positions (left front, right front, left rear, right rear) in the left and right direction and the front and rear direction of the roof box (the same direction as the front and rear direction of the vehicle). In a left and right open roof box 1, an arm member can be used to fix the opposite side of the opening side (right side for left opening and left side for right opening) by one person. In order to lift 40 and maintain the threaded portions at both ends of the arm member protruding from the inner surface of the roof box, it is necessary to devise such as temporarily fixing the arm member 140 to the crossbar 2 with an adhesive tape or the like, Further, when the operator's body touches the roof box 1 during the above work, the position of the roof box 1 moves with respect to the cross bar 2, so that the adhesive tape of the arm member 140 is peeled off from the cross bar 2, and the vehicle In some cases, the arm member 140 falls on the roof and scratches the roof.

Even when the adhesive tape of the arm member 140 is not peeled off from the cross bar 2, the arm member 140 is lifted from below the bottom of the roof box between the bottom of the roof box 1 and the roof, The operation of tightening the threaded portion with the nut 141 from the inside of the roof box 1 while maintaining the state in which the portion protrudes from the hole provided in the bottom of the roof box 1 to the inner surface of the roof box 1 Slipped and scratched the roof of the vehicle.

US Pat. No. 6,918,521 and Japanese Translation of PCT International Publication No. 2008-506585 are known as conventional techniques for solving the above-mentioned problems, and these techniques involve the crossbar 2 at a position below the bottom of the roof box 1. It comprises a clamping device having a clamping claw that can be tightened and an operation unit that moves the clamping claw.

In the above-mentioned US Pat. No. 6,918,521, as shown in FIG. 15, one clamping claw 142 is provided for one clamping device 143, and an opening through which the crossbar 2 can be taken in and out is one side of the clamping device. When the roof box 1 is fixed to the cross bar 2, the clamp device 143 is disposed in advance at a position avoiding an appropriate position, so that the roof box 1 is cross-bar. 2, while the roof box 1 is sufficiently lifted, the clamp device 143 having the opening is moved laterally to a state where the crossbar 2 can be taken in and out, and the bottom 145 of the clamp device main body is moved. Then, after the space surrounded by the clamp claws 142 is moved to the position of the crossbar 2, it is arranged at the inner position of the roof box 1. The clamp claw 142 needs to be in the closed position by the operation of the operation part of the clamp claw, and the work of fixing the roof box 1 to the cross bar 2 is not easy.

Further, since the clamp pawl 142 has a cantilever structure, the clamp pawl 142 is inevitably long, and there is a disadvantage that the mechanical parts are enlarged to increase the cost in order to obtain sufficient strength.

In Japanese translations of PCT publication No. 2008-506585, as shown in FIG. 16, a pair of clamp claws 146 are arranged in the vehicle front-rear direction with respect to one clamp device 144, and the roof box 1 is crossed. When fixing to the bar 2, the clamp device 144 is moved downward from the bottom inner surface of the roof box 1 at an appropriate position on the floor of the roof box 1, and the pair of clamp claws 146 and the lower surface 145 of the clamp device main body 144 are attached to the roof. Arranged at the appropriate position of the roof box in the state exposed from the lower surface of the box 1, and moved on the roof of the vehicle while lifting the roof box 1 with the clamp pawl 146 in the open position, When the clamp device 144 is at a proper position, the roof box 1 is lowered to lower the clamp device main body 144. 145 rides on the crossbar 2 and turns the rotary knob 147 for operation disposed at the inner position of the roof box 1 of the clamp device 144 to tighten the clamp pawl 146 in the closed position direction, thereby clamping the clamp device main body 144. The roof box 1 is fixed to the crossbar 2 by the lower surface 145 and the pair of clamp claws 146.

However, the opening / closing means of the clamp claw 146 of the clamp device 144 moves the up-and-down direction by the rotation of the operating element, and the contact that is movable in the up-and-down direction and comes into contact with the inner end of the clamp claw 146. 4 is arranged in the roof box 1 because the clamping device 144 becomes larger in the vertical direction and the clamping device 144 becomes an obstacle when storing a large load inside the roof box 1. When loading a load whose dimensions in the front-rear direction and the left-right direction are larger than the distance between the front-rear direction and the left-right direction of the rotary knob 147 of the clamp device 144, the upper end of the rotary knob 147 to the top surface of the roux box 1 is loaded. Only loads thinner than the distance can be loaded, and the top of the rotary knob 1447 to the top of the roux box 1 If for stacking thicker baggage than the distance had narrow baggage you can only load drawbacks width than the gap in the longitudinal direction and the lateral direction of the rotation knob 147.

In general, four clamping devices 3 are used for the table. The clamp device 3 is provided with a pair of front and rear clamp claws 4a and 4b that open and close in a direction coinciding with the front and rear direction of the vehicle when the roof box 1 is fixed to the cross bar 2. The clamp claws 4a and 4b Abutting portions 41a and 41b with opposite hook-shaped crossbars 2 whose surfaces are covered with an elastic material are provided on the surfaces facing each other, and the upper portions of the clamp claws 4a and 4b are disposed in the clamp body 5, Further, opening and closing means for the clamp claws 4 a and 4 b are disposed in the clamp body 5, and a contact portion 51 with the bottom inner surface 11 of the roof box 1 is provided on the lower surface of the clamp body 5. Note that the abutting portion 51 with the bottom inner surface 11 of the roof box 1 does not necessarily require the clamp body 5 to directly abut against the bottom inner surface 11 of the roof box 1, and the clamp body 5 may be connected to the roof box 1 via another component. You may contact | abut with the bottom part inner surface 11.

In the clamp body 5, the opening / closing means can change the distance between the restricting means for restricting the distance between the upper portions of the clamp claws 4a and 4b and the contact portions 41a and 41b of the clamp claws with the cross bar. It has a movable mechanism.

The restricting means includes a block 61 arranged to be movable in the front-rear direction within the clamp body 5, and the upper portion of the front clamp claw 4 a has a contact portion 42 a with the front end of the block 61. The upper part of the rear clamp claw 4b is formed with a contact part 42b with the rear end of the block 61, so that the front clamp claw contact part 42a and the rear clamp claw 4b are formed. The clamp pawl abutment portions 42b each act as a fulcrum of the distance regulating portion, and the distance between the pair of clamp pawl abutment portions 42a-42b is configured not to be smaller than the width of the block 61.

The movable mechanism includes the regulating means, a guide groove 55 formed in a front side portion of the side wall portion 54 formed between the front end portion 52 and the rear end portion 53 of the clamp body 5, and the side wall portion. 54 has a hole 56 formed in the rear portion, and a hole 43a is formed at a position between the contact portion 41a of the front clamp claw 4a and the upper contact portion 42a. A hole 43b is formed at a position between the contact part 41b of the claw 4b and the upper contact part 42b. The hole 43a formed in the front clamp claw 4a is formed on the side wall part 54 of the clamp body 5 by the shaft part 44a. The hole 43b formed in the rear clamp claw 4b is supported by the guide groove 55 so as to be rotatable and movable in the front-rear direction, and the hole 56b of the side wall 54 of the clamp body 5 is formed by the shaft 44b.

The bolt insertion hole 57 formed in the rear end portion 53 of the clamp body 5 and the bolt 81 inserted through the bolt insertion hole 57 and screwed into the nut 72 are used to reduce the distance from the bolt insertion hole 57 to the nut 72. Adjustable movable operating means.

In the above-described configuration, the pair of clamp claws 4a and 4b rotate in a direction in which the contact portions 41a and 41b with the crossbar are separated from each other, with the shaft portions 44a and 44b supporting the holes 43a and 43b as rotation axes. In this manner, springs 45a and 45b (which may use an existing biasing means other than the spring) are arranged. The rotational force generated by the biasing means is configured to act on the pair of clamp claws 4a and 4b with substantially the same force (however, the direction of the biasing rotation is opposite).

The movable operating means includes the bolt 81, a shaft portion 86 in which a screw portion 82 of the bolt 81 can be inserted, and a hole 85 in which a bolt head portion 83 is difficult to be inserted is formed in the center portion, and the shaft portion 86. A lever 9 that is pivotally supported, and a square hole 91 that is capable of transmitting a rotational force to the bolt 8 by engaging with a corner section 84 formed between the head portion 83 and the screw portion 82 of the bolt is formed inside. The minimum inner diameter of the hole 85 formed in the shaft portion 86 is such that the bolt 81 does not rotate even when the lever 9 is rotated in the axial direction of the bolt 8. It is comprised larger than the largest outer diameter of the part located in the said hole.

The lever 9 is in a position where the lever 9 stands upright from the state in which the inner side surface 93 of the operation portion formed by extending from the shaft support position of the lever 9 overlaps the upper portion 58 of the clamp body 5 by the shaft portion 86. The outer surface 94 of the operating portion of the lever 9 is configured to be rotatable to a position facing the bottom inner surface 11 of the roof box 1, and the outer peripheral end of the shaft support position by the shaft portion 86 of the lever 9 is further configured. A contact surface 95 that indirectly contacts the surface around the bolt insertion hole 57 formed in the rear end portion 53 of the clamp body 5 via the knob 92 is formed on the portion. The distance from the center position to the contact surface 95 is more when the lever 9 is in the upright state than at the position where the outer surface 94 of the operating portion of the lever 9 and the bottom inner surface 11 of the roof box 1 face each other. Big, further Lever 9 is constructed as an inner surface 93 of the operating portion of the lever than the distance in the upright position is greater in the State of the distance overlapping the top 58 of the clamp body 5.

Since the present embodiment is configured as described above, when the distance L from the bolt insertion hole 57 provided in the rear end portion 53 of the clamp body 5 to the nut 72 of the link member 7 is reduced, the hole of the front clamp claw 4a is formed. The support position of the shaft portion 44a of 43a moves in the direction of the rear clamp claw 4b along the guide groove 55 of the clamp body 5, and the contact portion 42a on the upper portion of the front clamp claw is moved to the front side of the block 61 along with the operation. The block 61 is moved in the rearward direction in contact with the other end. The rear end of the block 61 moves the abutting portion 42b on the upper portion of the rear clamp claw backward, so that the rear clamp claw 4b is placed on the rear portion of the side wall 53 of the clamp body 5. The abutting portion 41b of the clamp claw rotates and moves in the direction approaching the front clamp claw 4a with the pivotal support position with the formed support hole 56 as the center.

In this series of operations, the distance between the upper abutting portions 42a-42b of the pair of clamp claws 4a, 4b does not change, but the shaft portion 44a inserted through the hole 43a of the front clamp claw 4a serves as the clamp. Since the distance between the holes 43a-43b of the respective clamp claws is reduced by moving in the guide groove 55 formed in the side wall portion 54 of the body 5 in the rear direction, the shaft by the shaft portion 44a also in the front clamp claws 4a. The abutting portion 41a of the clamp claw rotates and moves in the direction approaching the rear clamp claw 4b with the support position (hole 43a) as the center. The force applied by the contact with the block 61 acts equally on the contact portions 42a and 42b of the pair of clamp claws, and the pair of clamp claws 4a and 4b is moved by the springs 45a and 45b. Since the contact portions 41a and 41b with the cross bar 2 are urged away from each other with the same force, the pair of clamp claws have the same rotation angle (with respect to the operation of the movable operation means). The direction of rotation is opposite to each other.

Since the present embodiment is configured as described above, as shown in FIG. 3, the lever 9 has an outer surface 94 of the operation portion of the lever 9 centered on the shaft support position by the shaft portion 86, and the bottom inner surface 11 of the roof box 1. 4 through a position where the lever 9 is upright as shown in FIG. 4, until the inner side surface 93 of the operation portion of the lever 9 overlaps the upper portion 58 of the clamp body 5 as shown in FIG. By rotating, the distance from the pivot support position by the shaft portion 86 of the lever to the contact surface 95 with the knob at the outer peripheral end portion becomes the maximum, so that the rear end portion 53 of the clamp body 5 is relatively. The distance from the formed bolt insertion hole 57 to the nut 72 of the link member 7 is reduced, and the contact portions 41a and 41b of the pair of clamp claws 4a and 4b with the cross bar 2 are closed as described above. Work in the direction

Note that the clamp 92 is adjusted by adjusting the screwing position between the bolt 81 and the nut 72 of the link member 7 by first rotating the knob 92 during the operation of fixing the roof box 1 to the crossbar 2. Once an appropriate fixing state of the roof box and the crossbar by the clamp device is set once in a state in which the lever is rotated until the operation portion of the lever 9 overlaps with the upper portion 58 of the body 5, When the roof box 1 is attached or detached, the operation can be easily performed only by the above-described rotation operation of the lever 9. It should be noted that the pivotable range of the lever 9 by the shaft portion 86 is not limited to the present embodiment, and can be freely set as necessary. In use, the front and rear direction of the clamping device may be opposite to that of the embodiment.

A modification of the first embodiment is shown in FIG. In this embodiment, the configuration other than the movable operation means is the same as that of the first embodiment, and the movable operation means of this embodiment includes a bolt 81 screwed with a nut 72 fixed to the link member 7, and the bolt 81. The shaft portion 87 is provided in a direction orthogonal to the axial direction, and the lever 9 is pivotally supported by the shaft portion 87. In this embodiment, the head portion 83 of the bolt 81 itself constitutes a shaft portion 87 extending in the left-right direction. However, a shaft portion is formed by inserting a pin or the like of another component into a hole provided in the bolt 81. May be.

The lever 9 is in a position where the lever 9 stands upright from the state in which the inner surface 93 of the operation portion formed by extending from the shaft support position of the lever 9 overlaps the upper portion 58 of the clamp body 5 by the shaft portion 87. The outer surface 94 of the operating portion of the lever 9 is configured to be rotatable to a position facing the bottom inner surface 11 of the roof box 1, and the outer peripheral end portion of the pivot support position by the shaft portion 87 of the lever 9. A contact surface 95 is formed in contact with the surface around the bolt insertion hole 57 formed in the rear end portion 53 of the clamp body 5.
