Detailed Description

Example 1

As shown in fig. 1, 2 and 3, it shows a first embodiment of the present invention of a bouncing roller skate convenient for quick switching, which comprises a skate body 1 provided with a springboard device 3 and a roller device 2, wherein the springboard device 3 is movably hinged with the skate body 1 by a rotating shaft 302 crossing a sole, and the roller device 2 is movably hinged with the skate body 1 by a supporting bracket 203 connected to the sole. The bouncing roller skate of the embodiment is also provided with a switching mechanism, and the switching mechanism comprises a first switching mechanism and a second switching mechanism, wherein the first switching mechanism can adjust the bouncing roller skate into a bouncing state, and the second switching mechanism can adjust the bouncing roller skate into a rolling state.

In this embodiment, the first switching mechanism may also be a linkage switching mechanism, that is, it can simultaneously retract the pulley part device 2 when the bouncing roller skate is adjusted to the bouncing state; the second switching mechanism may be a link switching mechanism that can simultaneously store the bouncer 3 when the bouncing roller skate is adjusted to the roller state.

The bouncing roller skate of the embodiment also comprises a resetting device 12 which can close the bouncing board device 3 and the pulley part device 2 completely and retract the bouncing board device and the pulley part device into a common shoe state.

Please note that the non-linked switching mechanism can only switch between the bounce mode and the normal shoe mode, or between the roller skating mode and the normal shoe mode.

Specifically, in this embodiment, the elastic member 301 of the springboard device 3 has a V-shaped elastic member sleeved into a shoe, an upper portion of the elastic member is an annular strip capable of being movably sleeved into the shoe body 1, a lower portion of the elastic member is provided with a through groove 305 corresponding to the pulley 201, and a bottom surface of the lower portion of the elastic member can be bonded with a sole plastic pad with anti-skid threads; the elastic member 301 is provided at a front portion facing the shoe body 1A rotating shaft 302 transversely penetrates through two sides of the sole, and a torsion spring 303 is also sleeved on the rotating shaft 302; the first control inhaul cable 4 penetrates through the connecting holes 306 on the two sides of the rear part of the annular noose and can be controlled to move downwards; two movable clamping seats 6 are respectively fixed on the sole and the upper at the two sides of the heel and comprise a clamping seat frame 601, an internal horizontal guide rail 602,Movable rack603 and a spring 604, wherein the movable rack 603 is connected with the second branch linkage cable 501 and the reset cable 12, and can respectively control unlocking; all the pull cables can be embedded in corresponding pipelines (pull rings or handles are exposed at the two sides of the back of the upper), and can change the direction through the pipelines or the pulleys; correspondingly, the movable clamping seat 6 is provided with two triangular lugs 304.

The pulley part device 2 is erected on a supporting support 203 by a front pulley 201 and a rear pulley 201 through a wheel shaft 202, two grooves 101 larger than the pulleys 201 are arranged at the lower part of the sole of the shoe body 1, 2 lifting rods 205 are respectively arranged inside each groove 101, one end of each lifting rod 205 is fixedly arranged at the lower part of the sole at one side of each groove 101 through a torsion spring rotating shaft 204, the middle of each lifting rod is hinged on the supporting support 203, a lug 206 is arranged at the other end of each lifting rod and connected with a second control cable 5, and the lug 206 is clamped on a small movable clamping seat 7; the number of the small movable clamping seats 7 is 4, the structure of the small movable clamping seats is basically the same as that of the large movable clamping seat 6, and the small movable clamping seats comprise a small clamping seat frame 701, a small horizontal guide rail 702 inside the small clamping seat frame, a small movable rack 703 and a small spring 704; the small movable rack 703 is connected with the first branch line linkage cable 401 to control unlocking.

The elastic piece 301 of the first control cable 4, which can pull the control springboard device 3, moves downwards, and meanwhile, the other section of first branch line linkage cable 401 is branched out to pull the control small movable clamping seat 7 to unlock, so that the bump 206 is separated from the clamping force of the small rack 703, and the pulley 201 of the pulley device 2 rises under the elastic action of the torsion spring rotating shaft 204 and is hidden in the groove 101; because the two sections of the stay cables have different pulling distances and amplitudes, the first branch line linkage stay cable 401 for pulling the unlocking small movable clamping seat 7 is lengthened or has elastic telescopic property to increase proper length, so that the stay cable which can not only pull and unlock but also can not interfere the other section of the stay cable for pulling and controlling the springboard device 3 and has larger downward movement amplitude of the plate is preferably used as the stay cable with the section of ー, and thus, the exposed stay cable can be pulled out and contracted back to the inside of the pipeline under the action of elastic force.

The second control cable 5 can pull the lifting rod 206 and the pulley 201 of the control pulley device 2 to move downwards, and meanwhile, the other branched second branch line linkage cable 501 can synchronously pull the control movable clamping seat 6 to unlock, so that the triangular convex block 304 loses the clamping force of the rack 603, and the springboard device 3 springs upwards and tightly adheres to the lower surface of the sole under the elastic action of the torsion spring 303; because the pulling distances and amplitudes of the two sections of cables are different, the second branch linkage cable 501 for pulling the unlocking movable clamping seat 6 is lengthened or has elastic telescopic property to increase the appropriate length, so that the cable which can be pulled for unlocking and cannot interfere the pulley 201 of the other section of pulling pulley device 2 to move downwards with a larger amplitude can be pulled, preferably, the ー sections of cables are designed to be elastic, and the exposed cables can be pulled out and retracted into the pipeline under the action of elastic force.

The reset inhaul cable 12 can independently pull and unlock the movable clamping seat 6 or the small movable clamping seat 7, so that the triangular convex block 304 or the convex block 206 is separated from the clamping force of the rack, and a common shoe state is formed.

In addition, in order to more conveniently and rapidly switch the modes, an auxiliary control member 11 (as shown in fig. 19) is further arranged in the embodiment, a sleeve 1101 is used for sleeving and hanging the auxiliary control member at a position close to a knee, the left through hole pipe 1102 and the right through hole pipe 1103 are respectively sleeved on the two sides of a thigh of the auxiliary control member, an auxiliary first cable 1104 and an auxiliary second cable 1105 are arranged at the lower part of the auxiliary control member, a hanging buckle is arranged at the lower part of the auxiliary first cable and can be connected with a pull ring of the first control cable, a hanging buckle is arranged at the lower part of the auxiliary second cable and can be connected with a pull ring of the second control cable, and a hanging buckle is arranged at the lower part of the auxiliary reset cable and can be connected with a pull ring of the reset cable.

The following will describe the operation and switching principle of the bouncing roller skate of the present embodiment, which is convenient and fast to switch, by taking the linkage switching mechanism as an example:

1. in a common shoe mode, the pulley 201 of the pulley part device 2 is upwards contracted and hidden in the lower groove 101 of the shoe body 1 under the elastic force of the torsion spring rotating shaft 204, the lower surface of the pulley 201 is level with the sole, the plate of the springboard device 3 is under the elastic force of the torsion spring 303, the elastic piece 301 is upwards closed to the sole part, and the plastic surface of sole patterns and the part at the front end of the sole are bonded under the elastic piece 301 and are simultaneously and directly contacted with the ground;

2. when the common shoe mode is switched to the bounce mode, a hand points to an upper hook pull ring to drive a first control cable 4, the first control cable 4 drives the bounce board device 3 through a pipeline or a turning wheel (at the moment, although a movable rack on the small movable clamping seat 7 is pulled at the same time, the first control cable does not play a role), the elasticity of a torsion spring 303 is overcome, pressure is applied downwards to pop out an elastic part 301, meanwhile, a triangular lug 304 moves downwards along a one-way rack 603 and is clamped at the lowest part of the movable clamping seat 6, and an elastic bounce shoe mode is formed, so that when walking or running, the gravity of a body forms an upward reaction force through the elastic part of the bounce board device 3, and the walking or running can be quicker and more labor-saving;

3. when the bounce mode is switched to the pulley mode, a finger is used for hooking and pulling the pull ring upwards to drive the second control cable 5, the second control cable 5 drives the pulley device 2 through a pipeline or a turning wheel, and the lifting rod 205 overcomes the elasticity of the torsion spring rotating shaft 204 to apply downward pressure to drive the support supporting piece 203 to extend out of the pulley 201 downwards; meanwhile, the second control cable 5 also synchronously controls the second branch line linkage cable 501 to pull the movable rack 603 on the movable clamping seat 6 to move towards the rear part of the shoe, so that the clamping force limitation on the triangular bump 304 is immediately released, the springboard device 3 springs upwards under the elastic force of the torsion spring 303 and tightly adheres to the underside of the sole, and the pulley 201 at the moment downwards crosses the through groove 305 exposing the springboard to form a roller skating mode, so that when walking or running, if the road condition is good (such as plane or downhill), the walking or running can be very fast and more labor-saving under the action of inertia;

4. when the pulley mode is switched to the bounce mode, like the operation of switching the common shoe mode to the bounce mode, the difference is that when the first control cable 4 pulls the bounce device 3 to form the bounce mode, the first branch line linkage cable 401 is synchronously controlled to pull the movable rack 703 on the small movable clamping seat 7 to move, the clamping force limit on the lug 206 is immediately released, the pulley 201 of the pulley part device 2 is quickly contracted upwards and hidden in the lower groove 101 of the shoe body 1 under the elastic force of the torsion spring rotating shaft 204, and the lower surface of the pulley 201 is level with the sole to form the bounce mode;

5. when the bounce mode needs to be switched to the common shoe mode, the reset inhaul cable 12 is pulled to pull the movable rack on the movable clamping seat 6 to move towards the rear part of the shoe, the clamping force limit on the triangular convex block 304 is immediately separated, and the bounce plate device 3 bounces upwards under the elastic action of the torsion spring 303 and is tightly attached to the lower surface of the sole; in addition, if the mode needs to be switched from the pulley mode to the ordinary shoe mode, the reset cable 12 needs to be connected to the small movable rack 703 on the small movable clamping seat 7.

In order to switch the mode more quickly and conveniently, the auxiliary control member 11 additionally arranged can be connected, so that the operation is quickly and conveniently carried out in a non-stop motion state, the waist bending is not needed, and only the fingers of two hands are used for pulling the pull ring of the auxiliary control member 11 close to the knee.

The arrangement and application of the mutual linkage mechanism of the embodiment are described in detail above.

Although the interlocking switching mechanism is described above, the present embodiment may employ an un-interlocking switching mechanism, except that the first branch wire interlocking cable 401 and the second branch wire interlocking cable 501 are not provided, and the reset cable 12 is directly connected in its entirety. Therefore, the mode can be switched between the bounce mode and the common shoe mode only, or between the roller skating mode and the common shoe mode only. Although the shoe body 1 is provided with the pulley part device 2 and the springboard device 3 at the same time, a non-linkage switching mechanism can be adopted only by switching one mode with a common shoe; if the bouncing mode and the roller-skating mode need to be switched to be used, the first control cable 4 or the second control cable 5 is pulled after the reset cable 12 is indirectly pulled to be reset to be in a common shoe state, so that two different settings can only be alternately used, and mutual interference or influence cannot be caused.

One section of the first control cable 4 can pull the elastic member 301 of the control springboard device 3 to move downwards to spring out the movable sole 13, and meanwhile, the ー th branch line linkage cable 401 is branched out to pull the control bolt 605 to unlock the hook 208, so that the pulley device 3 can be quickly turned upwards to two sides of the upper hung on the sole under the torsion action of the torsion spring hinge 105, and the ー th branch line linkage cable 401 pulling the unlocking movable bolt 605 is preferably an elastic cable due to different pulling distances and amplitudes of the two sections of cables.

The second control cable 5 can pull the support holder 203 through a pipeline to control the pulley devices 3 on two sides to be turned over and folded to enable the pulley 201 to be fixed in a vertical state downwards, meanwhile, the branched second branch line linkage cable 501 can synchronously pull and control the pawls 803 on the movable clamping blocks 8 to be unlocked, so that the racks 802 remove the clamping force of the pawls 803, the springboard device 3 upwards drives the movable soles 13 to bounce and tightly attach to the lower surfaces of the soles under the action of the elasticity of the torsion spring 302, and the second branch line linkage cable 501 pulling and unlocking the pawls 803 on the movable clamping blocks 8 is preferably an elastic cable due to the fact that the pulling distance and the pulling amplitude of the two sections of cables are different.

The reset cable 12 can independently pull the unlocking movable bolt 605 or the movable block device 8 to unlock, so that the pulley part device 2 is separated from the clamping force of the bolt 605 or the pawl 803 of the springboard device 3 is separated from the rack 802, and a common shoe state is formed.

The following will describe the operation and switching principle of the bouncing roller skate of the present embodiment, which is convenient and fast to switch, by taking the linkage switching mechanism as an example:

1. in a common shoe mode, the pulley part device 2 is integrally hung on two sides of the upper of the shoe body 1 under the torsion action of the torsion spring hinge 105, and the pulleys 201 are all upward; under the action of the elasticity of the torsion spring 303, the three plates of the elastic member 301 of the springboard device 3 drive the movable sole 13 forward and upward to close the lower surface of the sole part, and the plastic surface of the sole pattern bonded on the lower surface of the movable sole directly contacts the ground;

2. when the common shoe mode is switched to the bounce mode, a hand points to the upward hook pull ring to drive the first control cable 4, the first control cable 4 drives the springboard device 3 through the rack 802 on the movable block device 8 (at this time, although the bolt 605 on the fixing piece 104 is pulled at the same time, the bolt does not play a role), overcomes the elasticity of the torsion spring 303 to pull the 3 elastic pieces 301 downwards and drive the movable sole 13 to pop out downwards, meanwhile, the pawl 803 on the movable block device 8 clamps the limiting one-way rack 802, so that the 3 elastic pieces 301 cannot move forwards, and under the limiting action of the upper limiting block 14 and the lower limiting block 15, an elastic springing shoe mode is formed;

3. when the bounce mode is switched to the pulley mode, a finger is used for hooking and pulling the pull ring upwards to drive the second control cable 5, the second control cable 5 passes through a pipeline or a turning wheel and pulls the pulley device 2 through the fixing piece 104, the pulley device 2 overcomes the elasticity of the torsion spring hinge 105 and turns over downwards by 180 degrees, so that the pulley 201 is vertically placed downwards, furthermore, the hook 208 on the supporting piece 203 is inserted into the notch of the fixing piece 104, the pin 605 clamps the hook 208 under the elastic action of the spring 604, meanwhile, the second branch line linkage cable 501 also synchronously controls and pulls the pawl 803 on the movable clamping block 8 to be separated from the clamping force limit of the rack 802, and the bounce plate device 3 drives the movable sole 13 upwards forwards to bounce and tightly attach to the underside of the sole under the elastic action of the torsion spring 303, so as to form a stable wheel slip mode;

4. when the pulley mode is switched to the bounce mode, like the operation of switching the common shoe mode to the bounce mode, the difference is that when the first control cable 4 pulls the bounce device 3 to form the bounce mode, the ー th branch linkage cable 401 synchronously controls the pulling of the bolt 605 on the fixing part 104 to move at the same time, the clamping force limit on the clamping hook 208 is immediately released, and the pulley parts 2 on the two sides are integrally turned up and hung on the two sides of the upper under the torsion action of the torsion spring hinge 105, so that the bounce mode is formed;

5. when the bounce mode is switched to the common shoe mode, as long as the reset inhaul cable 12 is pulled, the pawl 803 on the movable clamping block 8 is pulled to be separated from the clamping limit of the movable rack 802 to the shoe, and the bounce plate device 3 drives the movable sole 13 to bounce forwards and upwards and tightly attach to the underside of the sole under the action of the elasticity of the torsion spring 303; in addition, if it is desired to switch directly from the pulley mode to the normal shoe mode, the return cable 12 is also connected to the latch 605 on the anchor 104 to control the return.

As in embodiment 1, the pulley unit 2 and the springboard unit 3 of embodiments 2 to 6 can be switched to the non-linked state by using a non-linked switching mechanism.

The aspects of the embodiments described above can be combined with or replaced by each other without mutual exclusion, and the connection can be reinforced by a metal plate or a metal frame strip built in the inner or bottom part according to the condition of the sole (such as rubber); in the use process, the same mode can be switched to the two shoes at any time according to different conditions, and various different modes of the two shoes can be switched rapidly at any time, such as: one shoe is switched into a pulley mode on a flat road surface, and the other shoe is switched into a bounce mode, so that one side of the bounce provides forward power for pedaling the foot on the ground, and the other side of the bounce slides forwards quickly by using the power and inertia, thereby saving labor and increasing the pleasure; sometimes, when both feet slide in a pulley mode, emergency braking action is needed, at the moment, the inhaul cable can be quickly pulled to switch one shoe into a bouncing mode in time, and then the inhaul cable is contacted with the ground to press down, so that powerful braking action is formed; or the mode is quickly switched to the common shoe mode, so that more powerful braking action is formed; the convenient, quick, free switching of multiple mode can avoid appearing unexpected improvement security, also can deal with all road conditions and scenes and make appropriate switching mode, and such a shoes are multi-purpose not only has increased the enjoyment of motion and amusement, also can regard as light laborsaving quick instrument of riding instead of walk at ordinary times to use.

Although the present invention has been described in terms of the above embodiments, it should be understood that equivalent modifications made in accordance with the present invention by those of ordinary skill in the art are intended to be included within the scope of the present invention without departing from the scope of the present invention.
