Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skate, and more particularly to a skate having a shoe member made of waist leather connected to a shell rotatably provided on a support frame for holding one or more wheels. The present invention relates to a brake device suitable for application.

[0002]

2. Description of the Prior Art In recent years, the known roller skates may have consisted of a shoe body joined to a support holding two sets of wheels in parallel, or Although it may have consisted of a shoe body coupled to a support frame holding one or more linearly arranged wheels, there was a problem with braking the wheels to adjust the speed of the skates.

It is well known to use normally rubber blocks or pads arranged on the toe or heel of the shoe body. In that case, the user applies the brake by pushing the shoe body forward or backward and bringing the free end of the pad or block into contact with the ground.

However, the above solution is not optimal. Because the above is
This requires that the shoe body (and therefore the frame connected to it) be rotated in the direction of the toes or heels, which leads to loss of balance and a fall.

Further, as well known, US Pat. No. 1,40
There is 2,010. It discloses roller skates with a user's leg provided with a band which can be tightly clamped at the upper part of the ankle and to which a rod is connected. The rod wraps around the rear of the user's leg and their ends are connected to a lever mechanism connected to a flap projecting from the wheel support frame so as to exert a lateral effect on the leg at the ankle portion. The parts are bent until they are joined. The lever mechanism projects from the rear portion of the frame and is connected to a plate formed at a lower portion of the frame so as to substantially follow a partial curve of a wheel facing the frame.

However, this solution does not eliminate the drawbacks. Firstly, a relative moment is generated between the band and the leg during exercise, and a comfortable feeling of use cannot be obtained. Furthermore, the plate is constantly moved each time the user bends his leg backward beyond a predetermined angle, and it is difficult and practically impossible to change such a state. Further, although the shape of the user's leg is different for each person, since the length of the rod is the same, the brake is operated at different rotation angles. Further, since the rod is located at the ankle portion, it is pressing there, which may cause discomfort or an impact leading to an accident. In addition, there is considerable wear on the wheels.

As a solution to some of the above drawbacks,
There is US Pat. No. 4,275,895. This discloses a braking device for a skate having two pairs of wheels in parallel with each other, the braking device acting on the rear wheels. The brake is constituted by a flap connected to the shoe body in the rear position. A blade is connected to the flap in a rearward position, and the blade is rotatably mounted on the support frame of the shoe body. The blade includes a cross member having a pair of C-shaped members formed at its side ends at its free end. This member follows the rearward rotation imparted to the flap so as to abut the rotating surface of the wheel, and abuts the opposing rear wheel.

However, this solution also has the following drawbacks. It is structurally complex and therefore difficult to commercialize. Further, it is necessary to provide a spring for returning the flap to a position where the C-shaped member does not come into contact with the wheel, which promotes structural complexity. Further, due to the structural shape of the brake, the pair of Cs, whether the rearward rotation imparted to the flaps is minimal, or even unintentional The letter-shaped member comes into contact with the wheel, which causes unnecessary braking action, which tends to cause loss of balance and lack of balance. Then, the contact of the C-shaped member with the rolling surface of the wheel leads to rapid wear of the wheel, resulting in poor rotation, which requires regular wheel replacement.

US Pat. No. 4,300,781 is also known. This relates to a braking device for a skate having a pair of wheels parallel to each other. The braking device further comprises a brake constituted by blades mounted pivotably about an axis across the rear end of a support frame for the shoe body. A plurality of pads facing the rolling surfaces of the pair of wheels are coupled to the ends of the blade.

This brake uses a cable capable of rotating the blade against a spring attached to a support for holding a pair of front wheels, and the pad serves as a rolling surface of the pair of rear wheels. Actuated to contact. The cable can be driven by a plurality of ring means or handle means attached to the band. Further, the band can be attached to a user's leg by a temporary connecting means.

However, this solution has serious drawbacks. First, the user has to make an unreasonable movement to activate the brake, which may lead to imbalance during exercise. Furthermore, the band may come off the leg while the ring is being pulled,
Braking operation is hindered. In any case, in particular, the legs are rhythmically moved laterally outward to evenly balance the movements of the legs and arms, but there are loose cables that can be inadvertently caught during the race. .

That is, an object of the present invention is to provide a brake device for skates that is extremely simple in structure and easy to industrialize, thereby eliminating the above-mentioned drawbacks of the conventional type brake device. Of the above objectives, what is important is to provide a braking device that can be activated by the user when needed. Another important object is to provide a braking device that can be released quickly and easily by the user. Another important object is to provide a device which allows the user to preset the operating state of the brakes to his or her desires, whether for leg shape or for any type of movement.
Another object is to provide a device which can protect the rolling surfaces of the wheels from wear. Yet another object is to obtain a device having the above-mentioned characteristics that it is reliable in use, safe, inexpensive to manufacture and can be applied to known skates.

These objects, and others that will become apparent hereafter, are achieved by the braking device described in the claims.

[0014]

Other features and advantages of the present invention will become apparent from the detailed description of the preferred embodiment depicted in the accompanying drawings (not limited to the same).

In the drawings, reference numeral 1 indicates a braking device used especially for the skates indicated by reference numeral 2.
This skate has a shoe body 3 made of a waist leather 4 which is connected to a shell 5 and which wraps around the rear side portion of the user's leg.
A frame 6 is mounted below the shell,
The frame carries one or more wheels, generally designated 7, which are arranged in a straight line relative to each other. A tightening lever for tightening the waist leather 4 and the shell 5 may be appropriately provided.

This braking device includes a first rod member 8 connected to the waist leather 4 and the braking mechanism 10, respectively.
And a second rod member 9. The brake mechanism 10 is connected to the frame 6 so as to be capable of reciprocating (swinging), or is rotatably attached to one axle of the wheels 7.

The first rod member 8 and the second rod member 9 are provided with first and second means capable of adjusting their working lengths. The first means is composed of a cylinder 11 having a thread formed therein, which is screwed to the threaded rod portion of the first bush 12. This first bush allows the waist shaft 4 to
It is rotatably attached near the outer edge 14 of the lower surface in the rear part of the. The other screw rod portion projects from the axial center of the shaft 15. In this case, the assembly thus combined constitutes the first rod member 8.

The first rod member is internally hollow and has a first sleeve 16 having one end having an opening through which the shaft 15 can pass and the other end having a screw formed therein.
It is slidably connected inside.

A corresponding screw is formed at one end of the second sleeve 17, and the one end is screwed to the end portion where the screw is formed inside. The sleeve 17 is hollow inside and is firmly connected to the second rod member.

More specifically, the second sleeve 17 is provided with a screw rod portion 18 on the side opposite to the end portion screwed to the first sleeve 16. The threaded rod portion 18 projects toward the brake mechanism 10 along the central axis and is screwed to a second means capable of adjusting the operating length of the second rod member 9. The second means is composed of a second bush, and the second bush has a mounting portion in which screws to be screwed with each other are formed along a central axis, and the second bush is rotated to the support 21 by the second shaft 20. It is movably attached. The support 21 constitutes the brake mechanism 10, and both ends of the wing-shaped extending portion thereof are rotatably attached to the frame 6 on one shaft of the wheel 7. And, at least one pad 22 that comes into contact with the ground is attached under the support 21.

The shaft 15 corresponds to the first sleeve 1
A head 23 is provided inside the unit 6. The head 23 has a substantially T-shape, and the second sleeve 1
The inside of 7 is opposed to the tab 24 protruding on the central axis thereof. The tab 24 acts as a stopper at the time of compression of the spring 26 that presses the brake mechanism 21 downward when the head 23 presses the tab 24.

A first elastic member 25 is provided coaxially with the shaft 15. The first elastic member 25 is preferably composed of a spring interposed between the open end of the first sleeve 16 and the wing body of the head 23 of the shaft. In addition, the second elastic member 26 has the tab 24.
It is installed coaxially with. The second elastic member 26 is
It is interposed between the base of the second sleeve 17 and the wing body of the head 23 of the shaft 15.

The apparatus further comprises at least one third
The elastic member 27 is provided. The third elastic member 27 is
It is constituted by a spring interposed between the frame 6 or the shell 5 and the wing body of the support 21 of the brake mechanism 10. In addition, the holding means 28
It is formed by a portion that protrudes laterally from the frame 6 and is raised by one step.

This braking device is used as follows. First, the first, second, and third elastic members have elastic constants that can support the brake mechanism 10 so that the pad 22 does not come into contact with the ground in the natural length. Therefore, the user can adjust the position of the brake mechanism by operating the first rod member 8 and the second rod member 9. For that purpose, their positions with respect to the cylinder 11 and the second bush 19 may be changed. Also, the user can change the preload of the springs 25 and 26 by tightening or loosening the first sleeve 16 and the second sleeve 17 to each other.

The gap between the end of the tab 24 and the head 23 prevents the brake mechanism 10 from being immediately actuated even when the waist leather 4 rotates backward. As a result, the waist leather 4 can freely vibrate (swing) when the brake operation is not performed.

Further, the presence of the first elastic member allows the waist leather 4 to bend forward. Further, the second elastic member 26 is suitable for adjusting the inclined state of the waist leather because the third elastic member 23 has a high elastic constant.

Once these adjustments have been made, the user applies a rearward rotation of the preset angle to the rear waist leather and operates the brakes. Making these adjustments also compensates for wear on the pad 22.

As described above, according to the present invention, the brake device in which the user can adjust the preset angle of the backward rotation applied to the waist leather is obtained, and the intended purpose is achieved.
This is accomplished by adjusting the first and / or the second rod member to a length suitable for use with respect to the support 21 and the waist leather 4. Further, the brake mechanism 10 is both easy to assemble and disassemble so as to obtain a device which is structurally simple and easy to industrialize. The device can also be applied to conventional skates.

It is composed of 5. The shaft 115 has a threaded end that is slidable along the axial center inside the second sleeve 117. The second sleeve 117 is hollow and is firmly connected to the second rod member 109.

The corresponding threaded end of the third sleeve 129 is screwed onto the threaded end of the shaft 115. The first elastic member 125 is disposed inside the third sleeve 129. The elastic member 125 is composed of a spring, and the spring urges the brake mechanism 110 by contacting a mounting portion 130 formed along the axial center of the base of the second sleeve 117.

Guide means for guiding the expansion / contraction operation between the first rod member 108 and the second rod member 109 is coaxially projected with respect to the third sleeve 129. The guide means is a rod 13 slidable inside a hole 132 connected to the mounting portion 130.
It is composed of 1.

In the illustrated example, the present apparatus is provided with means for changing the distance between the support 121 and the pad 122. This means is constituted by a screw 133. The screw head 134 is embedded inside the pad 122, while the threaded rod portion is provided inside the support 121 and is screwed into a matching threaded nut 135.

Also in this structure, the pad 122 is also used.
A brake device capable of adjusting the rearward inclination of the waist leather 4 for bringing the vehicle into contact with the ground is obtained, and the intended purpose is achieved. Further, since the third elastic member 127 having an elastic constant larger than that of the first elastic member 125 is provided, it is possible to control the backward rotation of the waist leather by slightly relaxing the force during exercise. It is possible. Moreover, the position of the pad 122 can be adjusted by the screw 133 according to the wear state. A further effect of the present embodiment is that the rod 131 has the hole 1
Since it can slide freely inside 32, the forward rotation of the waist leather is not disturbed by the connection with the brake mechanism. Further, the frame 10
Holding means 128 is provided which projects from 6 and contacts the support 121.

FIG. 3 shows another embodiment. In this embodiment, the first rod member 208 is the second rod member 209.
It can be extended and slid freely. Second rod member 2
09 is coupled to a second sleeve 217 having a shaft 215 slidably provided therein. The shaft 2
15 has a third sleeve 229 inside the second sleeve 217, and the third sleeve 229 is the second sleeve.

This contact occurs only while the waist leather 304 is being rotated, based on the shape given to the rod member 309.

The user adjusts the working length of the rod member, that is, the tilt angle of the waist leather 304 required to apply the brakes, so as to adjust the rod member 3
It is possible to change the shape of 09. This adjustment ensures that the pad 317 contacts the ground 312 only when the angle imparted to the rearward rotation of the waist leather 304 exceeds the limit to avoid inadvertent braking.

When the user returns him to his normal skate position, at the same time, the end 311 of the rod member 309 rises, thus immediately moving the pad off the ground.

In this way, even in the case of this embodiment,
A brake device that allows the user to appropriately set the backward rotation angle of the waist leather is obtained, and the intended purpose of the present invention is achieved. This is accomplished by giving the rod member the desired shape and length.

Next, reference numeral 40 in FIGS.
The brake device indicated by 1 is particularly suitable for use with the skates indicated by reference numeral 402.

This skate has a shoe body 403 connected to a shell 405 and composed of a waist leather 404 surrounding the rear side surface of the user's leg. A frame 406 is connected to the lower portion of the shell and carries one or more wheels 407 which are preferably linearly arranged relative to each other.
