Abstract

(57) [Summary] [Purpose] A safety device has been added so that the operating lever for unlocking the tiltable roll bar of a sports-type passenger car does not operate easily. [Structure] A holder-4 fixed to the mounting plate 1,
A safety member 10 having a knob 8 at one end and an abutment wall 9 at the other end is slidably fitted in the holder-4, and provided on an operation lever 12 pivotally supported by the holder-4. The stopper 15 is normally constituted by a member that abuts against the abutment wall 9 provided on the safety member 9 to prevent the operation lever 12 from rotating.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a roll-over type roll bar that can be tilted and stored in a Targa top type sports type passenger car that is provided with a roll bar for preventing a passenger from crashing into the ground when the passenger car capsizes. The present invention relates to the improvement of the operation lever for unlocking the lock device for fixing the lock device at each position when it is standing upright or stored in a tilted position.

[0002]

[Prior art]

 Conventionally, almost no Targa top type passenger car has a tilted roll bar, but in recent years a roll bar that can be tilted and stored has been installed, and a passenger car with a structure that combines both Targa top type and load star type. The lock device for fixing the roll bar in the upright position or the tilted storage position is released through the control cable, for example, in Japanese Utility Model Laid-Open No. 63-195075. The operation lever with a simple structure as shown in No. is attached near the console box so that the roll bar can be unlocked.

[0003]

[Problems to be solved by the device]

 However, the operation lever having a simple structure as described above does not have a safety mechanism, and if the operation lever is accidentally touched during driving, the roll lever may be tilted, which is extremely dangerous. When the lock is released and the hand is released from the operating lever, an unpleasant impact sound may be emitted when the safety member comes into contact with the side wall by the urging force of the spring.

[0004]

[Means for Solving the Problems]

 The operation lever for releasing the lock of the roll bar of the present invention is (a) a mounting plate provided with a pair of locking holes for locking the end of the control cable and a plurality of mounting holes. And (b) is substantially U-shaped, has a pair of guide pins that are fixed to the mounting plate with the opening facing upward, and that are sandwiched between the side walls of the mounting plate. And a pair of guide pipes through which the pair of guide pins can be inserted are provided and are slidably held in the holder by the guide pipes. A safety member that is provided with a knob on the other end and has an abutment wall on the other end, and is pressed by a spring toward one of the side walls; and (d) a pair that is rotatably supported by the connecting hole. Connecting arms, and control cables near the tip of each connecting arm. The operation lever is provided with an engaging hole for engaging the cable end member, and an operating lever provided with a stopper that normally abuts against the abutting wall to prevent rotation. Has been done. Further, it is preferable to interpose a sleeve made of synthetic resin between the guide pipe and the guide pin, and to provide a shock absorbing portion having a tip end portion on the side contacting with the side wall in a scoop shape.

[0005]

[Action]

 In the normal state, even if an attempt is made to operate the operating lever, the stopper provided on the operating lever is in contact with the contact wall provided on the safety member, so that the rotation is prevented. When attempting to rotate the operation lever, first, the safety member is slid against the biasing force of the spring to release the contact of the stopper with the contact wall, whereby the operation lever can be rotated. The inner cable of the control cable engaged with the cable end member engaging hole is pulled to release the lock mechanism of the roll bar. Further, by interposing a sleeve provided with a shock-absorbing portion with a tip in the shape of a scoop between the guide pipe and the guide pin, after operating the operating lever, the side wall is automatically abutted by the urging force of the spring. The impact of the safety member can be mitigated.

【Example】

 Next, the unlocking operation lever of the roll bar of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing a partially disassembled state showing an embodiment of an unlocking operation lever of a roll bar according to the present invention, and FIG. 2 shows an assembled state in FIG. FIG. 3 is a partially cutaway perspective view, and FIG. 3 is a partially cutaway plan view in FIG. 2.

In FIGS. 1 to 3, reference numeral 1 denotes a mounting plate having a pair of locking holes 2 and a mounting hole 3, and the mounting plate 1 has a substantially U-shape. The holder-4 is fixed with the opening portion facing upward. A pair of guide pins 5a and 5b are provided on the side walls 4a and 4b of the holder-4, and a pair of connecting holes 6 are further formed.

A safety member 10 having a knob 8 at one end, an abutment wall 9 at the other end, and a pair of guide pipes 7a, 7b through which the pair of guide pins 5a, 5b can be inserted. Is biased and pressed by the spring 11 toward the side wall 4b of the holder-4. An operation lever 12 has a pair of connecting arms 13 projecting downward in FIG. 1, and an engaging hole 14 for engaging the rope end member 17 is provided in the vicinity of the tip end thereof. ing. An operation lever 12 is rotatably supported by a pair of connecting holes 6 formed in the holder 4 via the connecting arm 13. Further, a stopper 15 is provided at an appropriate position in the middle of the pair of connecting arms 13 so as to normally abut the abutment wall 9 and prevent the operation lever 12 from rotating.

The operation lever 12 for releasing the lock of the roll bar having the above-mentioned structure is normally provided with a stopper 15 provided on the operation lever 12 even if the operation lever 12 is operated in the direction of the arrow A in FIG. Since it contacts the contact wall 9 provided on the safety member 10, it does not rotate. In order to unlock the roll bar, first, the safety member 10 is slid in the direction of D arrow as shown by the broken line in FIG. 2 against the biasing force of the spring 11 in the direction of C arrow by the knob 8. By making a state in which 15 does not contact the contact wall 9, the operation lever 12 can rotate in the direction of the arrow A, and the inner cable of the control cable engaged with the engaging hole 14 is sewn. Release the lock mechanism by pulling.

Further, as shown in FIG. 3, sleeves 16a and 16b made of synthetic resin are inserted into the gaps between the guide pipes 7a and 7b and the guide pins 5a and 5b, and the tip on the side wall 4b side is formed into a scoop shape. By adopting the structure in which the buffer portions 16c and 16d are provided, as shown in FIG. 2, when the operation lever 12 is operated in the direction of arrow A to release the lock mechanism and then returned in the direction of arrow B, Even if the safety member 10 automatically returns in the direction of the arrow C by the biasing force of the spring 11 and comes into contact with the side wall 4b, the impact can be mitigated.

[0012]

[Effect of device]

 The operation lever for unlocking the roll bar of the present invention is extremely safe because the operation lever does not operate easily by incorporating the safety member, and is issued after the operation lever is operated. There is no unpleasant sound of the safety member colliding with the side wall.
