Abstract

PROBLEM TO BE SOLVED: To prevent a braking face from being worn ununiformly by constituting an inline roller skate in such a state that a brake pad is guided so as to be slid on a load bearing structure along an axis crossing at approximately right angles with the brake face. SOLUTION: A load bearing structural body 10 is provided with a plurality of projecting parts 11 having recessed parts 12. Recessed parts 14 and projecting parts 15 guided by the projecting parts 11 and the recessed parts 12 are formed in a slider 13. A hole 20 for storing a ring nut 21 is formed in the load bearing structural body 10 and the ring nut 21 can be rotated from the outside. When the ring nut 21 is rotated counterclockwise to adjust the position of the brake pad 9 (hereinafter called a pad), the slider 13 is slid parallel along the axis X and the distance from the ground to the pad 9 is reduced. The inclination of the brake face 9a to the ground is held in a fixed state during adjusting of the pad 9. As a result, the abrasion of the pad 9 becomes uniform so that the braking capacity can be secured and held at all times.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An inline roller skate according to an embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the inline roller skate 1 of the present embodiment includes a wheel carrier 2 extending in one direction, and the wheel carrier 2 has two side portions 3 arranged in parallel. 4 (see FIGS. 1 and 4). A plurality of wheels 5a to 5d having a plurality of axes arranged in parallel with each other are rotatably supported between the two side portions 3 and 4 in a state where they are aligned with each other.

A shell 6 is attached to the wheel carrier 2 at a position facing the plurality of wheels 5a to 5d, and a cuff 7 is articulated to the shell 6 via a pin 6a.

The inline roller skate 1 is equipped with a brake 8 having a brake pad 9 (hereinafter, referred to as a pad). The brake 8 has a box-shaped load bearing structure 10.

The load bearing structure 10 is provided with a plurality of projections 11 having recesses 12 formed therebetween (see FIG. 2), and the sliders 13 are formed by the projections 11 and the recesses 12. Guide means for guiding is configured. The slider 13 has a recess 14 at a position corresponding to the protrusion 11, and a protrusion 15 at a position corresponding to the recess 12 (see FIG. 2).

According to such a connection structure, the slider 1
Numeral 3 is guided in the load bearing structure 10 so as to be slidable along the X axis in the figure.

The load bearing structure 10 is fixed to the wheel carrier 2 by a three-point connecting device.

The three-point connecting device has two arms 16, 17
And an appendage 18 having a hole. The three-point connecting device includes a wheel 5 via two arms 16 and 17.
Each hole 19 which is articulated about the axis of d and is formed on each of the side parts 3 and 4 via the appendage 18 (see FIG. 1)
Is attached to the wheel carrier 2.

The load bearing structure 10 has a hole 20 for accommodating the annular nut 21, and a portion of the load bearing structure 10 from the outside of the load bearing structure 10 to the annular nut 21 through the hole 20. It can be accessed (contacted) in a specific way.

A center hole is formed in the annular nut 21. The center hole is formed in the first portion 2 having a regular polygonal cross section.
2 and a second part 23 having a smaller diameter than the first part 22 and a circular cross section.
Are communicated with each other via a shoulder 24.

In the first portion 22 of the central hole, the head 25 of the screw 26 is completely fitted and accommodated adjacent to the shoulder 24. And the head 25 of the screw 26 is thus
Is completely fitted into the first portion 22, so that the screw 26 rotates with the rotation of the annular nut 21.

The screw 26 is screwed into a female threaded nut 27. The nut 27 has a pair of grooves 28, 29 defined by C-shaped portions 30, 31 of the slider 13, respectively. And is restrained.

The slider 13 has a C-shaped portion 30,
The lips 32, 33 are respectively provided at positions opposing the base 31. The lips 32, 33 are formed in grooves 34 formed in the T-shaped mounting portion 36 of the pad 9 by interlocking connection. , 35 are removably engaged with each other.

Groove 3 between lips 32, 33 and pad 9
A flat U-shaped anti-vibration element 40 is inserted in each of the reference numerals 4 and 35. The anti-vibration element 40 is formed of an elastic cushioning material, and is an element for attenuating the vibration generated in the pad 9 during braking. Functions as an element for attenuating vibration transmitted to the foot.

The surface 9a formed in the direction perpendicular to the axis X is formed on the opposite surface of the pad 9 on the side opposite to the side on which the mounting portion 36 is provided, and brakes the inline roller skate 1. It is provided for pressing against the ground at the time. Therefore, in the following description, the surface 9a is referred to as a braking surface.

In such a configuration, the annular nut 21
When the screw 26 in the nut 27 is twisted, the slider 13 slides together with its pad 9 in the axial direction relative to the load bearing structure 10 along an axis X perpendicular to the braking surface 9a. The position of the pad 9 with respect to the ground indicated by the plane P can be adjusted according to the skater's unique requirements. For example, adjustment can be made to compensate for the progress of the wear amount of the pad 9.

The connection between the male screw and the female screw selected between the screw 26 and the nut 27 is irreversible.
Only by rotating the screw 26 can the screw 26 and the nut 27 be relatively rotated. On the other hand, for example, the translational movement of the nut 27 due to the load acting on the slider 13 when the pad 9 is pressed against the ground P locks the screw 26 and the nut 27 and prevents the screw 26 from rotating.

FIG. 3 shows a state in which the brake 8 is in the first adjustment position. Note that the first adjustment position is a state where the pad 9 is as far away from the plane P as possible with respect to the load bearing structure 10.

In the state shown in FIG.
When the annular nut 21 is rotated so as to remove from the screw 26, the slider 13 slides in parallel along the axis X,
As a result, the distance from the plane P to the pad 9 decreases until the distance becomes minimum (see FIG. 4). During the adjustment movement of the pad 9, the inclination of the braking surface 9a with respect to the plane P is always kept constant.
As a result, the wear of the pad 9 becomes uniform, so that the pad 9
This has the advantage that the braking capacity can always be secured and maintained even if the tire is worn.

Further, according to such adjustment of the pad 9, it is possible to always keep the distance and the inclination angle of the braking surface 9a with respect to the ground P constant according to the progress of the wear amount of the pad 9. . As a result, when the skater lifts the toe of the inline roller skate 1 during braking, the lifting angle can always be set to the same angle, or set to a desired angle equal to a state where the pad 9 is not worn, for example. It becomes possible.
