are connected to each other.

Prior to the connection, the coil springs 100 are placed in the spaces 101a and 101b between the skirt portion 76 and the connecting portion 78 of the covering member 70, respectively. This coil spring 1
One end of 00 is connected to each pin 91 and also to coil spring 100.
The other ends of the coil springs 100 bias each pin 91 in a direction perpendicular to its axis. The spring receiver 102 is an adjustment knob 104
The notch 103 is engaged with a guide 108 that is screwed into a screw 106 fixed to the connector 78 and protrudes from the connecting portion 78, and is held unrotatable.

As a result, when the adjustment knob 104 is turned, the spring receiver 102
moves forward and backward, the compressive force exerted on the pin 91 of the coil spring 100 changes, and the force for attaching and detaching the mast by the pair of pins can be changed. A retaining ring 105 is attached to the screw 106 to restrict movement of the screw 106 in the axial direction.

At the lower end of the base 30 of the mast 12, as shown in FIG.
A pin 110 is attached by a washer 112 and a retaining ring 114 and projects downward. This pin 110 has a groove 116 extending all the way around its tip. When the pin 110 is inserted into the hole 79 provided in the connection part of the mast step 18, the tip of the pin 110 pushes apart the pair of rollers 92 of the mast step 18, and when the rollers 92 fit into the grooves i16 of the hinge 110, the mast 12 The base 30 of will be fixed to the mast step 18.

The long means 20 includes a pawl 120 that can engage and disengage the teeth 34 of the step guide 16, a spring 122 that biases the pawl 120 toward the teeth 34 to engage the teeth 34, and a spring 122 that biases the pawl 120 toward the teeth 34 to engage the teeth 34. An operating member 124 is provided that resists and causes the claw 120 to separate from the tooth. In the illustrated example, one locking means 20 is provided before and after the mast step 18 at intervals. As described later,
The two opening and closing means 20 differ from each other in the arrangement of the claws 120.

As shown in FIGS. 7 and 8, the claw 120 has a pair of engaging portions 126 and a connecting portion 128 that connects the inner connecting portion 126.
Provide for both. The retaining portion 126 has two flat surfaces 130 and 131 at different levels on its upper side, and an inclined surface 132 extending over the inner flat surface. As shown in FIG. 3, the pair of engaging parts 126 are located on both sides of the holding part 72 of the mast step 18 and
It is provided at a spacing S3 opposite to the teeth 34 provided at 8. Insert the claw 120 into the window 90 of the holding part 72 of the mast step 18 so that the inner flat surfaces 130 and 131 of the engaging part 126 are vertical, and position the pair of engaging parts 126 on both sides of the holding part 72, respectively. , Turn the entire unit to make the inner surface horizontal, and make it look like this! The claw 120 is used at 'i. Claw 12
0 can move the window 90 of the holding part 72 downwards by 2'. When placing the claws 120 in the first and second spaces 84, 85 provided at intervals before and after the mast step 18, the directions of the claws in one space and the claws in the other space are reversed. . As a result, when one pawl 120 is released from the teeth 34, the other pawl 120 can only move the mast step 18 in one direction, either forward or rearward.

In the illustrated example, the spring 122 is a coil spring, and its lower end is locked in a recess 134 of the holding portion 72 of the mast stay 18, and its two wheels are locked in the pawl 120. This spring is a compression spring that biases the pawl 120 toward the tooth 34. When the pawl 120 is biased by the spring 122, the pawl 120 engages the tooth groove 33 of the tooth 34, as shown in phantom in FIG.
A flat surface 13'0 and an inclined surface 132 are located within the flat surface 1
r+i 131 has a size to abut the tooth root surface, and the vertical surface 133 engages the tooth.

In the illustrated example, the operating member 124 is a pedal, and includes a sliding portion 136 and a foot rest portion 138 that are slidably inserted into a first space 84 (second space 85) provided in the holding portion 68 of the mast step 18. and has. The sliding part 136 is inserted into the space and applied to the claw 120, and the screw 140 is screwed in from below the claw 120 to connect the operating member 124 and the claw 120. As a result, the vertical movement distance of the operating member 124 is limited to the vertical length of the window of the holding portion 72 of the mast step 18.

As mentioned above, since the pawl 120 is biased toward the tooth 34 by the spring 122, the operating member 124 is biased upwardly. Then, the operating member 124 is
When pressed down against the spring force of 22, the pawl 120 is lowered together with the operating member 124, and the pawl 120 is released from the teeth 34. To this end, the spacing S1 between the teeth 34 of the step guide 16 and the locking portion 44 is set to a size such that the claw 120 comes off from the teeth 34 when the claw 120 takes the lower limit position.

The holding part 72 of the mast step 18 is attached to the step guide 1.
The mast step 18 is inserted into the step guide 16 through the notches 48 and 49 of the mast 12, and the pin 110 of the base 30 of the mast 12 is supported, and the board 11 is ready for use. When changing the position of the mast 12, for example, to the left in FIG. ), the user operates the operating member 124 of the long means 20 located at the rear to release the locking claw 12.0 from the south 34. Then, when the mast 12 is pushed forward, the claw 120 of the front locking means 20 is engaged with the tooth 34, but a downward force is exerted from the south 34 to the claw 120 due to the action of the inclined surface 132, and this The force overcomes the spring force of the spring 122,
The pawl 120 is pushed down under the teeth 34 and moves the mast step 18 forward. However, since the vertical surface 133 of the pawl 120 of the forward locking means 20 engages the teeth 34, the mast step 18 cannot be moved rearwardly. In this way, with two long means,
By releasing the pawl 120 of one locking means from the tooth 34 and keeping the pawl 120 of the other locking means engaged with the tooth 34, the mast step 18 is advanced by a plurality of tooth pitches, each time Since the pawl 120 engages the teeth, it is possible to prevent the mast step 18 from moving too much.

Contrary to the above, when changing the position of the mast 12 toward the rear, the front opening 1. The operating member 124 of the locking means 20 is operated to release the claw 120 of this locking means from the teeth 34.

When the step guide is provided with a plurality of downward facing teeth, as in the above example, sand and other foreign matter will not accumulate in the grooves of the teeth, so that the teeth and mouth 1. A good engagement state can always be maintained with the claw of the lifting means, and the movement and fixation of the mast step can be ensured.

Moreover, it is possible to prevent the teeth and the claws of the locking means from becoming thick, thereby increasing durability.

According to the present invention, the device for supporting the mast on the board allows the mast to be attached and detached, and the force for attachment and detachment can be adjusted, so that the mast can be removed from the port during transportation. Furthermore, by increasing the attachment/detachment force during sailing, it is possible to prevent the mast from coming off, and when suspending sailing, the mast can be quickly removed from the board by weakening the attachment/detachment force.
