Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a skating shoe, and more particularly to a braking device suitable for application to a skating shoe having a shoe member made of quarter leather connected to a shell provided on a support frame holding one or more wheels. .

[0002]

2. Description of the Related Art In recent years, known roller skates may be constituted by a shoe body coupled to a support holding two sets of wheels parallel to each other, or Although constituted by a shoe body coupled to a support frame holding one or more linearly arranged wheels, there have been problems with braking the wheels to adjust the speed of the skate.

[0003] It is well known to use blocks or pads, usually made of rubber, arranged on the toe or heel of the shoe body. In such a case, the user protrudes the shoe body forward or backward, and the brake is activated by bringing the free end of the pad or block into contact with the ground.

[0004] However, the above solution is not optimal. Because the above ones give the user
This requires rotating the shoe body (and thus the frame connected to it) in the direction of the toe or heel, which leads to loss of balance and a fall.

[0005] Further, as well known, US Pat.
There is 2,010. This discloses a roller skate in which a band is provided on the user's leg which can be tightened tightly on the ankle and to which a rod is connected. The rods wrap the back of a user's leg and have their ends connected to a lever mechanism connected to a flap protruding from the wheel support frame so as to laterally affect the leg at the ankle. The parts are bent until they are joined. The lever mechanism protrudes from a rear portion of the frame and is connected to a plate formed at a lower portion of the frame and substantially along a partial curve of a wheel facing the lower portion.

However, this solution does not solve the disadvantage. First, a relative moment is generated between the band and the leg during exercise, and a comfortable use feeling cannot be obtained. Moreover, the plate is constantly being moved each time the user bends the leg backwards beyond a certain angle, and it is difficult and practically impossible to change such a state. In addition, since the lengths of the rods are the same regardless of the shape of the user's legs, the brakes are operated at different rotation angles. Furthermore, since the rod is located in the ankle part, it presses there, which may cause discomfort or an impact that may lead to an accident. In addition, considerable wear of the wheels is also seen.

To solve some of the above disadvantages,
There is U.S. Pat. No. 4,275,895. This discloses a braking device for a skate with two sets of wheels parallel to each other, acting on the rear wheels. The brake is constituted by a flap connected to the shoe body in a rearward position. A blade is connected to the flap in a rearward position and the blade is rotatably mounted on a support frame of the shoe body. The blade has at its free end a transverse member having a pair of C-shaped members formed at side ends. This member comes into contact with the rear wheel facing the rear wheel following the rearward rotation applied to the flap so as to contact the rotating surface of the wheel.

[0008] However, this solution also has the following disadvantages. It is structurally complex and therefore difficult to industrialize. Also, a spring must be provided to return the flap to a position where the C-shaped member does not contact the wheel, which contributes to structural complexity. Further, due to the structural shape of the brake, even if the rearward rotation imparted to the flap is minimal or due to undesired movement, the paired C The letter-shaped member comes into contact with the wheel, which causes unnecessary braking operation, which tends to cause loss of balance and lack of proportion. And, the contact of the C-shaped member with the rolling surface of the wheel causes abrupt wear of the wheel, resulting in poor rotation, and requires frequent replacement of the wheel.

[0009] US Patent 4,300,781 is also known. This relates to a braking device for skates having a pair of wheels parallel to each other. The brake device further comprises a brake constituted by a blade rotatably mounted about an axis transverse to the rear end of the support frame for the shoe body. Then, a plurality of pads facing the rolling surfaces of the pair of wheels are coupled to the end of the blade.

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

However, this solution has significant disadvantages. First, the user must perform excessive movements to activate the brake, which may cause loss of balance during exercise. Further, the band may come off the leg while the ring is being pulled,
Braking operation is disturbed. In any case, in particular, there are loose cables that rhythmically move the legs laterally outward to evenly balance the movement of the feet and arms, which can inadvertently get caught during the race. .

It is therefore an object of the present invention to provide a brake device for a skate shoe which is extremely simple in construction and easy to industrialize, thereby eliminating the above-mentioned disadvantages of the conventional brake device. Among the above objects, what is important is to provide a brake device that can be operated when needed by a user. Another important object is to provide a braking device that can be quickly and easily released by a user. Another important objective is to provide a device that allows the user to preset the operating state of the brakes as he wishes, whether for the shape of the legs or for any type of exercise.
Another object is to provide a device that can protect the rolling surface of the wheel from wear. Yet another object is to provide a device having the above-described features that is reliable, safe to use and inexpensive to manufacture, and can be applied to known skates.

[0013] These and other objects which will become apparent hereinafter are achieved by the brake device as claimed.

[0014]

BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the present invention will become apparent from the detailed description of a preferred embodiment thereof, taken in conjunction with, but not limited to, the accompanying drawings.

In the drawings, reference numeral 1 designates a brake device used particularly for the skating shoes indicated by reference numeral 2.
This skate shoe has a shoe body 3 consisting of a quarter 4 connected to a shell 5 and wrapping around the rear side of the leg of the user.
A frame 6 is attached below the shell,
The frame supports one or more wheels, preferably indicated by reference numeral 7, arranged linearly with respect to each other. A tightening lever for tightening the quarter 4 and a shell 5 may be appropriately provided.

The brake device comprises a first rod member 8 connected to the quarter 4 and the brake mechanism 10, respectively.
And a second rod member 9. The brake mechanism 10 is connected to the frame 6 so as to be able to reciprocate (oscillate), 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 operation length. The first means comprises a cylinder 11 having a thread formed therein, which is screwed to a threaded rod portion of a first bush 12. The first bush is fixed by the first shaft 13 to the quarter 4.
Is mounted rotatably in the vicinity of the lower surface outer edge 14 in the rear portion of the lower surface. The other threaded rod projects from the center of the shaft 15. In this case, the assembly combined in this way constitutes the first rod member 8.

The first rod member is a first sleeve 16 which is hollow inside and has one end having an opening through which the shaft 15 can pass and the other end having a thread formed inside.
Are 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 having a screw formed therein. The sleeve 17 is hollow inside and is firmly connected to the second rod member.

More specifically, the second sleeve 17 has a threaded rod portion 18 on the side opposite to the end screwed to the first sleeve 16. The threaded rod portion 18 protrudes along the central axis toward the brake mechanism 10 and is screwed to second means capable of adjusting the operating length of the second rod member 9. The second means is constituted by a second bush. The second bush has a mounting portion in which screws to be screwed together are formed along the central axis, and is turned to the support 21 by the second shaft 20. It is movably mounted. The support 21 constitutes the brake mechanism 10, and both ends of the wing-shaped extension portion are rotatably attached to the frame 6 on one axis of the wheels 7. At least one pad 22 that contacts the ground is mounted below the support 21.

The shaft 15 is connected to the first sleeve 1
6, a head 23 is provided. The head 23 has a substantially T-shape, and the second sleeve 1
Inside 7, it faces a tab 24 protruding on its central axis. The tab 24 functions as a stopper for compressing a 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 constituted by a spring interposed between the open end of the first sleeve 16 and the wing of the head 23 of the shaft. Further, the second elastic member 26 is connected to the tab 24.
And coaxially. This second elastic member 26
It is interposed between the base of the second sleeve 17 and the wing of the head 23 of the shaft 15.

The device may further comprise at least one third
An elastic member 27 is provided. This third elastic member 27
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. Further, the holding means 28
It is formed by a portion that is raised one step from the frame 6 to the side.

The brake device is used as follows. First, the first, second, and third elastic members have an elastic constant in a natural length that can support the brake mechanism 10 so that the pad 22 does not contact the ground. Therefore, the user can adjust the position of the brake mechanism by operating the first rod member 8 and the second rod member 9. To do so, the position of both members with respect to the cylinder 11 and the second bush 19 may be changed. The user can also 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 activated even if the quarter 4 rotates backward. Thereby, free vibration (oscillation) of the quarter 4 when the brake operation is not performed is enabled.

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

After these adjustments have been made, the user applies a rearward rotation of the rear quarter leather at a preset angle and performs a brake operation. Making these adjustments also compensates for wear of the pad 22.

As described above, according to the present invention, a brake device that allows a user to adjust the preset angle of the backward rotation given to the quarters is obtained, and the intended object is achieved.
This is achieved by adjusting the first and / or second rod members to a length suitable for use with respect to the support 21 and the quarter 4. Further, the assembly and disassembly of the brake mechanism 10 are both simple so as to obtain a device that is structurally simple and easy to industrialize. The device can also be applied to conventional skate shoes.

The first rod member 108 is connected to the shaft 11
5. The shaft 115 has a threaded end formed inside the second sleeve 117 so as to be slidable along the axial center. The second sleeve 117 is hollow inside and is firmly connected to the second rod member 109.

The corresponding threaded end of the third sleeve 129 is screwed to the threaded end of the shaft 115. A first elastic member 125 is disposed inside the third sleeve 129. The elastic member 125 is configured by a spring, and the spring urges the brake mechanism 110 by abutting on a mounting portion 130 formed along the axis center at the base of the second sleeve 117.

A guide means for guiding the expansion and contraction operation between the first rod member 108 and the second rod member 109 projects coaxially 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.

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

Also in the case of this configuration, the pad 122
A brake device that can adjust the backward inclination of the quarter 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 quarter by, for example, slightly relaxing the force during exercise. It is possible. Further, the position of the pad 122 can be adjusted by the screw 133 according to the wear state. A further advantage of this embodiment is that the rod 131
Because it can slide freely inside 32, the forward rotation of the quarter is not impeded by the connection with the brake mechanism. Further, the frame 10
6 is provided with a holding means 128 projecting from the support 6 and contacting the support 121.

When the user returns him to the normal skating position, at the same time the end 311 of the rod member 309 rises, so that the pad immediately leaves the ground.

[0044] In this way, those of the present embodiment,
A brake device that allows the user to appropriately set the backward rotation angle of the quarter is obtained, and the intended object of the present invention is achieved. This is achieved by providing the rod member with the desired shape and length.

Next, in FIG. 6 to FIG.
The brake device indicated by 1 is particularly suitable for use in a skate shoe indicated by reference numeral 402.

The skate has a shoe body 403 connected to a shell 405 and composed of a quarter 404 surrounding the rear side surface of the user's leg. A frame 406 is connected to the lower portion of the shell and holds one or more wheels 407, preferably arranged linearly with respect to each other. A fastening lever 408 is attached to the quarter 404 and the shell 405.

In this manner, the user can selectively change the distance between the lower outer edge 525 of the quarter 507 and the support 514 of the pad 516. Therefore, the user can select the contact state between the pad 516 and the ground 517 according to the required angle of the backward inclination of the quarter 507 according to the detailed requirements regarding the physical shape, the type of skating, and the like. Thus, the brake can be effectively applied.

The brake device is very simple and safe to use. The third shaft 519
Can be locked in a preset position by tightening it with a lock nut 528, for example.
It goes without saying that the number of the mounting portions 520 is not limited to the above embodiment.

FIGS. 17 and 18 show another embodiment in which the means for adjusting the position of the quarter 607 and the second end 618 of the rod member 609 relative to each other is provided by a third shaft 619.

This brake support 714 also has a series of vertically arranged holes 718. These holes
The shaft 7 attached to the lower end of the rod member 709
19 is suitable for engagement. It is easily understood that the operation of this brake can be changed by disposing the shaft 719 in different holes 718. In FIG. 19, only two holes 718 are shown corresponding to two different brake positions, but it is needless to say that a number of holes may be provided as required.

FIG. 20 shows a skating shoe 802 with a brake device 801 with some modifications. This brake device 801 has a series of holes 818 formed at the lower end of a rod member 809.

As another modified example (not shown), a series of two sets of adjustment holes may be formed in each of the lower end of the rod member and the brake support.

It goes without saying that the materials constituting the individual members according to the present invention and their dimensions can be appropriately selected and viewed.

[0073]

As described above, according to the brake device of the present invention, by adjusting the rod member to a length suitable for use with respect to the support and the quarter, the backward rotation preset given to the quarter can be provided. The angle can be adjusted by the user. Further, by making these adjustments, wear of the pad can be prevented as much as possible.

Also, the distance between the pad and the ground can be adjusted so that the conditions necessary to obtain the braking action can be detected, and thus they can be determined by the physical characteristics of each person or the type of each skate. Alternatively, it is possible to detect according to the pad wear condition.

Further, it is possible to select an angle at which the backstrip is rotated backward beyond the angle after the pad starts to contact the ground, thereby keeping the brake state of the user constant at all times, and preventing accidental skating. Brake and pad wear can be prevented.

Further, since the structure is simple, the assembly and
Decomposition is easy and industrialization is easy. In addition, excellent effects such as being applicable to conventional skate shoes can be achieved.
