Description

Exercise bicycle and its handle height adjustment device and seat height adjustment device

The present invention relates to an exercise bicycle capable of adjusting handle height or seat height according to the user's body shape, and a handle height adjustment device and a seat height adjustment device thereof.

Generally speaking, exercise bikes are used as indoor exercise equipment for strengthening muscles. With an exercise bike, you can exercise by rotating the wheels through the pedaling action. Such exercise bikes can be classified into spinning bicycles capable of performing rotational motion and indoor bicycles having forwardly rotating pedals like bicycles.

Due to its feature of pedaling for fitness, the spinning bicycle adopts a non-freewheel structure, while the indoor bicycle adopts a freewheel structure.

The non-freewheel structure used in spinning bicycles transmits power to the wheels when the pedals are rotated in both forward and reverse directions, causing the wheels to rotate.

In addition, the freewheel structure used in indoor bicycles only transmits power to the wheels when the pedals are rotated in the forward direction. However, when the pedal is stopped or rotated in reverse, no power is transmitted to the wheels.

In addition, Korean Patent Publication No. 2017-0111669 (published on October 12, 2017, invention name: pop-up bicycle handle) discloses a structure that adjusts the height of the handle by rotating a lever. On pop-up bicycles, the height of the handlebars can be adjusted hydraulically when the driver operates a lever while driving. However, since such a handlebar height adjustment device requires a separate hydraulic drive device, the weight of the pop-up bicycle is significantly increased and the manufacturing cost may be increased.

Korean Public Patent Publication No. 2019-0073955 (published on June 27, 2019, invention name: bicycle frame) discloses a method for adjusting the height of a bicycle seat by installing a first clamp and a second clamp on the upper and lower sides of the seat tube. device. After adjusting the height of the seat tube, tighten the bolts and nuts to the first clamp and the second clamp. As the bolts and nuts are tightened, the height of the saddle is fixed by compressing the seat tube against the seat tube. However, since a separate tool must be used in order to tighten the bolts and nuts, the height of the saddle cannot be adjusted without this tool. Furthermore, when the first clamp and the second clamp are loosened through the bolts and nuts, the height of the seat tube and saddle may change.

The exercise bicycle according to the embodiment of the present invention will be described below.

FIG. 1 is a perspective view schematically showing the exercise bicycle of the present invention; and FIG. 2 is a side view schematically showing the internal structure of the exercise bicycle of FIG. 1 .

Referring to FIGS. 1 and 2 , the exercise bicycle 1 according to the embodiment of the present invention can adjust the height of the handle 143 or the height of the seat 153 according to the user's body shape. The exercise bicycle 1 includes: a frame part 120; a spacer part 125; a faucet 140; a seat shell part 126; a seat tube 150; a faucet locking part 200; and a seat tube locking part 300.

The base 113 is installed on the lower side of the frame part 120 to support the frame part 120 . The base part 113 may be formed in the shape of a rectangular plate connected to the lower side of the frame part 120 . Such base 113 may be formed in various shapes.

The frame part 120 supports the drive shaft part 133 and the rotation shaft part 160. Such frame portion 120 can be formed into various structures according to the load distribution and structure of the exercise bicycle 1 .

The housing 110 is installed to cover the outside of the frame part 120 . A frame part 120, a flywheel 170, a braking device 135 (not shown), etc. are installed inside the housing 110. The housing 110 may be formed such that the front and rear sides are rounded, and both sides in the left and right directions have a flat plate shape. Circular disc hole portions 111 are formed on both sides of the housing 110 .

The rotating disk 131 is mounted in the disk hole 111 . The rotating disk 131 is formed in the shape of a circular plate. The housing 110 and the rotating disk 131 shield the frame part 120, the flywheel 170, the brake device 135, etc. from the outside. Thus, access to users, young children, and companion animals can be prevented to eliminate the possibility of injury. In addition, external foreign matter can be prevented from adhering to components such as the frame portion 120, the flywheel 170, the brake device 135, and the like. Such a housing 110 forms the appearance of the exercise bicycle 1 .

The center portion of the rotating disk 131 is connected to both sides of the drive shaft portion 133 . The pedals 130 are respectively connected to the peripheral portions of each rotating disk 131 . The pedal 130 of one rotary disk 131 and the pedal 130 of the other rotary disk 131 are arranged on both sides of the drive shaft portion 133 in the diameter direction (an angle of 180°). When the user steps on the pedal 130 , the rotating disk 131 rotates around the drive shaft 133 .

The drive shaft portion 133 is provided to penetrate the center portion of the drive wheel (not shown). The driving wheel 135 and the rotating shaft part 160 are connected through a power transmission part (not shown) such as a belt or a chain. When the user steps on the pedal 130, the rotating disk 131 rotates. As the rotating disk 131 rotates, the driving shaft part 133 and the rotating shaft part 160 rotate. Since the rotating disk 131 covers the disk hole 111, even if the rotating disk 131 is rotated by stepping on the pedal 130, injuries to the user or young children can be prevented. In addition, the rotating disk 131 can shield the driving shaft portion 133, the driving wheel 135, and the like so that the internal components of the exercise bicycle 1 are not visible from the outside. Therefore, it is possible to prevent children, pets, or parts of the body from entering the inside of the housing 110 .

On the front side of the housing 110, the spacer portion 125 extends upward. The spacer part 125 is supported by the frame part 120 . The spacer portion 125 is formed to be hollow inside so that the faucet 140 (stem) is coupled to the spacer portion 125 . Faucet 140 includes a faucet post 141 height-adjustablely coupled to spacer portion 125 . The display unit 144 may be disposed above the faucet 140 . The display section 144 can output exercise information such as the speed of the exercise bicycle 1, rotation load, and the like. The faucet 140 is height-adjustable coupled to the spacer portion 125 . The handle 143 is connected to the upper side of the faucet 140 .

The upper side of the spacer part 125 is disposed further forward than the lower side, so that the spacer part 125 is disposed obliquely in the up-down direction. Therefore, as the height of the faucet 140 is raised, the handle 143 moves away from the front side. Therefore, as the height of the user increases, the height of the handle 143 and the distance in the front-to-back direction can be appropriately adjusted according to the height of the user by adjusting the height of the handle 143 .

The seat shell portion 126 is installed inside the housing 110 . The seat shell portion 126 may be mounted to penetrate the interior of the housing 110 . The seat shell part 126 may be provided so as to be inclined in the up-and-down direction of the housing 110 . The seat shell part 126 is provided between the drive shaft part 133 and the rotation shaft part 160. Such seat shell portion 126 can be formed in various shapes such as a polygonal tube or a circular tube.

The seat tube 150 is height-adjustable coupled to the interior of the seat shell portion 126 . The upper end of the seat tube 150 is provided on the rear side relative to the lower end thereof and is provided inclined in the up-down direction. The seat 153 is installed on the upper side of the seat tube 150 . The seat tube 150 is height-adjustable mounted inside the seat shell portion 126 . The cross section of the seat tube 150 can be formed in various shapes according to the shape of the seat shell portion 126 .

Since the seat tube 150 and the seat shell portion 126 are inclined in the up-down direction, the seat 153 moves away from the handle 143 as the height of the seat tube 150 increases. Therefore, as the height of the user increases, the height of the seat 153 and the handle 143 and the distance in the front-to-back direction can be appropriately adjusted according to the height of the user by increasing the height of the seat tube 150 .

Flywheel 170 is shaft-coupled to rotating shaft portion 160 . The rotation shaft 160 is coupled to the rotation center of the flywheel 170 , and the rotation shaft 160 and the flywheel 170 are connected via a one-way bearing (not shown). The one-way bearing is arranged concentrically with the rotation shaft portion 160 and the flywheel 170 . In addition, the rotating shaft portion 160 and the flywheel 170 can be restricted or released through a clutch gear module (not shown). The clutch gear module is also disposed concentrically with the rotating shaft portion 160 and the flywheel 170 . The flywheel 170 rotates in freewheel mode and non-freewheel mode.

The flywheel mode refers to an operation mode in which the flywheel 170 rotates due to the restricting force of the one-way bearing when the rotating shaft portion 160 rotates in the forward direction, and does not rotate when the rotating shaft portion 160 rotates in the reverse direction. In the flywheel mode, when the rotating shaft part 160 rotates in the reverse direction, the rotating shaft part 160 idles on the flywheel 170 .

The non-flywheel mode refers to an operation mode in which flywheel 170 rotates regardless of whether rotation shaft portion 160 rotates forward or reverse. In the non-flywheel mode, the rotating shaft portion 160 and the flywheel 170 are locked to each other through the clutch gear module and rotate together.

The stator 180 is installed in the frame part 120 to adjust the rotation load of the flywheel 170 by applying magnetic force to the flywheel 170 . The stator 180 is an electromagnet in which a coil 182 is wound around an iron core 181 . As power is applied to coil 182, magnetic force is generated in stator 180. The magnetic strength of the stator 180 can be adjusted by adjusting the current applied to the coil 182 of the stator 180 .

As the rotational load of flywheel 170 (magnetic strength of stator 180) increases, the pedaling force of pedal 130 increases, and as the rotational load of flywheel 170 (magnetic strength of stator 180) decreases, the pedaling force of pedal 130 decreases. decrease. Therefore, by adjusting the magnetic strength of the stator 180, the rotation load of the flywheel 170 can be adjusted to adjust the user's pedaling force.

On the other hand, in the exercise bicycle 1 according to the present invention, the flywheel 170 may be provided on the rear side or the front side with respect to the drive shaft portion 133 . The shapes of the frame portion 120 and the housing 110 change depending on the mounting position of the flywheel 170 . In addition, the positions of the drive shaft part 133 and the rotation shaft part 160 also change.

FIG. 3 is a cross-sectional view schematically showing the faucet locking part of the exercise bicycle of FIG. 1 ; FIG. 4 is an exploded perspective view schematically showing the faucet locking part of the exercise bicycle of FIG. 3 ; FIG. 5 is a schematic diagram 3 is a cross-sectional view of a state in which the faucet locking part adjusts the height of the faucet column; and FIG. 6 is a cross-sectional view schematically showing a state in which the faucet locking part of FIG. 3 fixes the position of the faucet column.

Referring to Figures 3 to 6, the exercise bicycle 1 of the present invention includes a handle height adjustment device. The handle height adjustment device includes: a spacer part 125; a faucet 140; and a faucet locking part 200.

The faucet 140 is height-adjustable coupled to the spacer portion 125 . The faucet post 141 is connected to the underside of the faucet 140 . The first locking portion 142 is formed on the faucet column 141 . The first locking portion 142 may be a plurality of first locking holes arranged along the length direction of the faucet column 141 . In addition, the first locking portion 142 may be a plurality of first locking grooves or first locking platforms arranged along the length direction of the faucet column 141 . Such first locking portion 142 can take various forms as long as it is restricted by the faucet locking portion 200 and fixed in position.

Faucet post cover 145 is coupled to the interior of spacer portion 125 . The faucet pillar cover 145 is disposed parallel to the length direction of the spacer portion 125 . The faucet pillar cover 145 may be formed in the shape of a rectangular plate to cover the rear side of the spacer part 125 . The first through hole portion 146 and the second through hole portion 147 may be formed in the faucet pillar cover 145 .

The faucet locking part 200 is inserted into the first locking part 142 to fix the position of the faucet 140 and pressurizes the faucet 140 to press the faucet 140 against the spacer part 125 . Since the faucet locking part 200 is inserted into the first locking part 142 of the faucet 140 to pressurize the faucet 140 when restricting it, even if an external force or impact is applied to the faucet 140, the restricting force and the pressing force of the faucet locking part 200 can be prevented from being destroyed. Lift. Therefore, it is possible to prevent the adjusted height of the faucet 140 from changing.

In addition, even if the insertion restriction force of the faucet lock part 200 is released, if the faucet lock part 200 pressurizes the faucet 140, the height-adjusted state of the faucet can be maintained as it is. Even if the pressing force of the faucet lock part 200 is released, if the faucet lock part 200 maintains the insertion restriction force of the faucet 140, the faucet 140 can maintain the height-adjusted state. In this way, as long as the faucet lock part 200 acts on the faucet 140 with either the restricting force or the pressing force, the height of the faucet 140 can be prevented from changing.

The structure in which the faucet locking part 200 applies both the restricting force and the pressurizing force to the faucet 140 can adopt various forms. An example of the faucet locking part 200 is described below.

The faucet locking part 200 includes: a faucet locking lever 210; a faucet pushing part 220; and a faucet restricting part 230.

The faucet locking lever 210 is rotatably mounted on the spacer portion 125 . For example, the faucet locking lever 210 may be hingedly coupled to both sides of the first through-hole portion 146 in the faucet column cover 145 . The faucet locking lever 210 is exposed to the outside.

The faucet pushing part 220 is connected to the faucet locking lever 210 and moves to press the faucet 140 toward the spacer part 125 when the faucet locking lever 210 rotates. The faucet pushing part 220 is movably inserted into the first through hole part 146 of the faucet pillar cover 145. The faucet pushing part 220 includes: a pushing slide block 221 inserted into the first through hole part 146; and a pushing plate part 222 connected to the pushing slide block 221 to compress the faucet column 141. The pushing slider 221 is pressurized by the faucet locking rod 210, and the pushing plate portion 222 presses the faucet column 141. The pushing plate portion 222 may be formed into a flat plate shape to increase the pushing rod and pressing area. The faucet pushing part 220 pressurizes the faucet 140 to press the faucet 140 against the spacer part 125 . Therefore, it is possible to prevent the faucet 140 from changing its position in the up-down direction. In addition, the faucet 140 is pressed by the spacer part 125, so that the faucet 140 can be prevented from moving in the spacer part 125 when the exercise bicycle 1 is running.

The faucet restricting part 230 is connected to the faucet pushing part 220 to move together with the faucet pushing part 220, and is inserted into the first locking part 142 to fix the position of the faucet 140. The faucet regulating part 230 is installed in the second through-hole part 147 of the faucet column cover 145. The faucet restricting part 230 may be provided on the upper side or the lower side of the faucet pushing part 220. As the faucet locking lever 210 rotates, the faucet restricting part 230 and the faucet pushing part 220 move together, so the faucet restricting part 230 is inserted into the first locking part 142 to prevent the position of the faucet 140 from changing, and the faucet pushing part 220 pushes the faucet 140 The spacer part 125 is pressed to prevent the faucet 140 from moving.

As described above, when the faucet locking lever 210 rotates, the faucet pushing part 220 and the faucet restricting part 230 double prevent the position of the faucet 140 from changing, so that the adjusted height of the handle 143 can be constantly maintained. Therefore, the user can exercise in a posture that matches their body shape or interests.

A hinge coupling portion 211 is formed in the faucet locking lever 210 to allow a faucet hinge pin (not shown) to pass therethrough. The hinge coupling part 211 is provided to correspond to the faucet pushing part 220 located on one side of the faucet locking lever 210 .

A pressurizing cam 213 may be convexly formed in the hinge coupling part 211 to pressurize and depressurize the faucet pushing part 220 when the faucet locking lever 210 rotates. The pressurizing cam 213 is formed to protrude from the end of the hinge coupling part 211 toward the faucet pushing part 220 . The rotation locus of the pressure cam 213 is arranged outside the rotation radius of the hinge coupling portion 211 . Therefore, when the faucet locking lever 210 is closed downward, the pressurizing cam 213 pressurizes the faucet pushing part 220 so that the faucet pushing part 220 presses the faucet column 141 against the spacer part 125 . In addition, when the faucet lock lever 210 is opened to the upper side, the pressurizing cam 213 rotates to disengage from the faucet pushing part 220 so that the faucet pushing part 220 is not pressurized.

The push lock part may also include: a first link part 235; and a second link part 236.

The first link part 235 is connected to the faucet locking lever 210 and the faucet pushing part 220 . A pair of first link parts 235 are coupled to both sides of the faucet locking lever 210 and the faucet pushing part 220 in parallel. The pair of first link parts 235 is connected to both sides of the first fixed shaft part 233a. Thus, when the faucet locking lever 210 rotates, the first link portion 235 and the faucet pushing portion 220 can move to pressurize or relieve pressure on the faucet post 141.

The second link part 236 is connected to the faucet pushing part 220 and the faucet restricting part 230 so that the faucet pushing part 220 and the faucet restricting part 230 move together. A pair of second link parts 236 are coupled to both sides of the faucet pushing part 220 and the faucet restricting part 230 in parallel. The pair of second link portions 236 are connected to both sides of the second fixed shaft portion 232 . The second link portion 236 is fixed on both sides of the faucet restriction portion 230 to move together with the faucet restriction portion 230 . Therefore, the faucet pushing part 220 and the faucet restricting part 230 move together through the second link part 236.

The first link part 235 may be arranged parallel to the moving direction of the faucet pushing part 220 (the direction perpendicular to the height adjustment direction of the faucet 140). The second link portion 236 may be arranged parallel to the height adjustment direction of the faucet 140 . At this time, the first link part 235 and the second link part 236 may be arranged perpendicularly or nearly perpendicularly to each other.

Referring to Figures 7 to 9, the exercise bicycle 1 of the present invention includes a seat height adjustment device. The seat height adjustment device includes: a seat shell portion 126; a seat tube 150; and a seat tube locking portion 300.

The seat tube 150 is height-adjustable coupled to the seat shell portion 126 . The second locking portion 152 is formed on the seat tube 150 . The second locking portion 152 may be a plurality of second locking holes arranged along the length direction of the seat tube 150 . In addition, the second locking portion 152 may be a plurality of second locking grooves or second locking platforms arranged along the length direction of the seat tube 150 . Such second locking portion 152 can take various forms as long as it is restricted by the seat tube locking portion 300 and fixed in position.

The seat tube cover 155 is mounted on the upper side of the housing 110 . Seat post cover 155 may form part of housing 110 . The seat tube 150 is installed to penetrate the seat tube cover 155 . The seat tube cover 155 may be formed in the shape of a rectangular plate to cover a portion of the upper side of the housing 110 . The seat tube 156 may be formed on the seat tube cover 155 .

Since the seat tube locking part 300 is inserted into the second locking part 152 of the seat tube 150 to restrict and pressurize the seat tube 150, even if an external force or impact is applied to the seat tube 150, restriction of the seat tube locking part 300 can be prevented. force and pressurizing force are released. Therefore, it is possible to prevent the adjusted height of the seat tube 150 from changing.

Furthermore, even if the insertion restriction force of the seat tube locking portion 300 is released, if the seat tube locking portion 300 pressurizes the seat tube 150, the seat tube 150 can maintain its height-adjusted state. Even if the pressing force of the seat tube locking part 300 is released, as long as the seat tube locking part 300 maintains the insertion restriction force of the seat tube 150, the seat tube 150 can maintain its height-adjusted state. In this way, as long as the seat tube locking portion 300 acts on the seat tube 150 with either the restricting force or the pressurizing force, the height of the seat tube 150 can be prevented from changing.

The structure in which the seat tube locking portion 300 applies both the restricting force and the pressurizing force to the seat tube 150 can take various forms. An example of the seat tube locking portion 300 will be described below.

A pressing protrusion 311 may be formed on the seat tube locking lever 310 to press the seat tube pushing part 337 . The pressing protrusion 311 is formed to protrude from the seat tube locking lever 310 toward the seat tube pushing portion 337 . Therefore, when the seat tube locking lever 310 is closed horizontally, the pressing protrusion 311 pressurizes the seat tube pushing part 337 so that the seat tube pushing part 337 presses the seat tube 150 against the seat shell part 126 . In addition, when the seat tube locking lever 310 is opened upward, the pressing protrusion 311 rotates downward to disengage from the seat tube pushing part 337 so that the seat tube pushing part 337 is not pressurized. Such pressing protrusion 311 only presses the seat tube pushing part 337 to press the seat tube 150 against the seat shell part 126 when the locking lever of the seat 153 is closed.

The pulley portion 338 is installed on one side of the seat tube restriction portion 330 in the moving direction, and the wire portion 320 is connected to the seat tube restriction portion 330 through the pulley portion 338 . At this time, both sides of the pulley portion 338 are connected to the fixed bracket 322 , and the fixed bracket 322 is fixed to the housing 110 . Depending on the positions of the seat tube restricting portion 330 and the seat tube locking lever 310 or surrounding structures, the position and number of the pulley portions 338 can be variously changed.

The wire part 320 connects the seat tube locking lever 310 and the seat tube restricting part 330, and the pulley part 338 supports the wire part 320. As the seat tube locking lever 310 is rotated, the seat tube restricting part 330 can be inserted into the second locking part 152 or removed from the second locking part 152. The second locking part 152 comes off.

The seat tube restriction part 330 includes: a holding part 331; a fixed rod part; and a seat tube elastic member 335.

The holding part 331 is fixed to the seat shell part 126. The holding portion 331 may be formed in a cylindrical or polygonal cylindrical shape with the seat tube 150 side open. The holding part 331 is fastened to the seat shell part 126. The holding portion 331 is arranged to face the second locking portion 152 of the seat tube 150 .

The seat tube fixing rod part 332 is movably installed inside the retaining part 331 and inserted into the second locking part 152 to fix the position of the seat tube 150 . The seat tube fixing rod part 332 is inserted into the locking hole part 126a formed in the seat shell part 126. The seat tube fixing lever 332 is movable in a direction perpendicular to the height adjustment direction of the seat tube 150 .

The seat tube elastic member 335 exerts elastic force to press the seat tube fixing rod portion 332 toward the second locking portion 152 . The seat tube elastic member 335 exerts an elastic force toward the seat tube fixing lever portion 332 in the direction in which the seat tube fixing lever portion 332 is inserted into the second locking portion 152 . The coil 182 spring may be provided as the seat tube elastic member 335 . Therefore, when no external force is applied to the seat tube locking lever 310 , the seat tube elastic member 335 exerts an elastic force so that the seat tube fixing lever portion 332 does not fall off from the second locking portion 152 .

A stopper 333 may be formed on the outer surface of the seat tube fixing rod part 332 to limit the movement range of the seat tube fixing rod part 332. The stopper 333 may slidably contact the inner side of the holding part 331. When the seat tube fixing rod part 332 is inserted into the second locking part 152, the stopper 333 comes into contact with the outer surface of the locking hole part 126a. Therefore, the insertion depth of the seat tube fixing rod portion 332 into the second locking portion 152 can be limited.
