[0003] At this time, the exercise bike comprises a support frame disposed on the floor surface, a guide tube provided to extend upward from the support frame, a support bar movably coupled to the guide tube, a saddle provided at the top of the support bar, a rotating shaft provided to penetrate both sides of the support frame, and pedals provided at both ends of the rotating shaft.

Specific details for implementing the invention

[0023] The present invention will be described in detail below with reference to the attached exemplary drawings.

[0026] And, the support bar (3) is configured in a square tube shape that is inserted into the interior of the guide tube (2), and is coupled so that the support bar (3) does not rotate while moving up and down inside the guide tube (2).

[0027] Additionally, a fixing member (2a) is provided on one side of the upper part of the guide tube (2) to be coupled to the support bar (3) and fixed so that the support bar (3) does not move up and down, thereby adjusting the height of the saddle (4) by raising and lowering the support bar (3) in the up and down direction, and by fixing the support bar (3) using the fixing member (2a), the height of the saddle (4) can be freely adjusted.

[0028] Furthermore, the left-right reciprocating structure of the exercise bike saddle according to the present invention is identical to that of the prior art, comprising: a support member (10) provided on the lower side of the saddle (4) to support the saddle (4); a reciprocating support means (20) provided on the upper side of the support bar (3) to support the support member (10) so that it slides laterally; a drive shaft (30) rotatably coupled inside the guide tube (2) and connected to the rotation shaft (5) so that it rotates in conjunction with the rotation shaft (5) when the rotation shaft (5) rotates; and a reciprocating drive means (A) connecting the drive shaft (30) and the support member (10) so that when the drive shaft (30) rotates, the support member (10) and the saddle (4) slide laterally.

[0029] And, according to the present invention, the reciprocating support means (20) is composed of a support bracket (21) provided to extend in the front-rear direction at the top of the support bar (3) as shown in FIGS. 4 to 8, front-rear guide members (22, 23) respectively provided on the front-rear upper surface of the support bracket (21), and front-rear slide members (24, 25) slidably coupled to the front-rear guide members (22, 23) in the lateral direction.

[0030] The support bracket (21) is configured in a triangular plate shape that widens toward the rear, and a connecting part (21a) is formed concavely upward in the center of the lower side to which the upper end of the support bar (3) is connected, and a through hole (21b) through which the drive shaft (30) passes is formed in the center of the connecting part (21a).

[0031] In addition, front and rear extension parts (21c, 21d) with upper surfaces that are horizontal are provided at the front and rear ends of the support bracket (21).

[0032] The above front and rear guide members (22, 23) utilize LM guides or various other types of sliding bushes that are coupled to extend laterally to the front and rear ends of the support bracket (21).

[0033] At this time, the front and rear guide members (22, 23) are fixed to the front and rear extension parts (21c, 21d) so that their upper surfaces are horizontal.

[0034] The above front and rear slide members (24, 25) are configured in a block shape with a shorter lateral width compared to the front and rear guide members (22, 23), and are coupled to the upper side of the front and rear guide members (22, 23) such that their upper surfaces are horizontal, so that they slide laterally along the front and rear guide members (22, 23).

[0035] The above support member (10) is composed of a support plate (11) provided to be inclined downward toward the rear, a fixing plate (12) provided on the upper part of the support plate (11) and coupled to the lower side of the saddle (4), an upper guide (13) provided to extend in the front-rear direction on the lower side of the support plate (11), a front support member (14) extending upward from the upper surface of the front slide member (24) and having its upper end fixed to the front end of the support plate (11), and a rear support member (15) fixed to the upper surface of the rear slide member (25) and having its upper end fixed to the rear end of the support plate (11).

[0036] The support plate (11) is provided with a hinge member (11a) on its upper surface that supports the fixed plate (12) so that it can rotate laterally, and a pair of cushioning springs (11b) that support both sides of the rear lower surface of the fixed plate (12).

[0037] The above fixing plate (12) is fixed to the lower side of the saddle (4) with a fixing bolt, and while connected to the hinge member (11a), both sides of the rear end are supported by the cushioning spring (11b) so that they rotate elastically in the lateral direction, thereby supporting the saddle (4) to rotate elastically in the lateral direction when the user steps on the pedal (6) while sitting on the saddle (4).

[0038] The upper guide (13) uses an LM guide provided to extend in the front-rear direction at the center of the lower side of the support plate (11).

[0039] The above-mentioned front support member (14) is configured with a first fixing part (14a) that extends in the front-rear direction and is fixed to the upper surface of the front slide member (24), a first extension part (14b) that extends upward from the front end of the first fixing part (14a), a second extension part (14c) that extends upwardly inclined from the upper end of the first extension part (14b), and a second fixing part (14d) that extends backward from the upper end of the second extension part (14c) in a manner parallel to the support plate (11) and is fixed to the upper surface of the front end of the support plate (11).

[0040] The rear support member (15) is configured to extend laterally and is composed of a fixing part (15a) fixed to the upper surface of the rear slide member (25), a vertical part (15b) extending upward from both ends of the fixing part (15a), and an extension part (15c) extending in an adjacent direction from the upper end of the vertical part (15b) and fixed to the lower surface of the support plate (11).

[0041] The above drive shaft (30) is configured in the shape of a hexagonal rod with a pointed top end and is rotatably coupled to the inside of the guide tube (2) so as to be parallel to the guide tube (2), and the lower end is connected to the rotation shaft (5) by a bevel gear.

[0042] The above reciprocating drive means (A) is composed of a rotating tube body (40) which is rotatably coupled inside the support bar (3) and whose lower end is coupled to the drive shaft (30), a rotating arm (50) which extends in the front-rear direction and whose front end is coupled to the upper end of the rotating tube body (40) and rotates together with the drive shaft (30), and a slide block (60) which is rotatably coupled to the rotating arm (50) and slidably coupled to the upper guide (13) in the front-rear direction.

[0043] As shown in FIGS. 3 and FIGS. 9, the above-mentioned rotating tube body (40) is composed of a circular tube body extending in the vertical direction, and a blocking plate (41) is provided at the bottom, and a hole (41a) is formed in the central part of the blocking plate (41) to which the drive shaft (30) is coupled.

[0044] The hole (41a) is formed in a hexagon corresponding to the drive shaft (30), so that when the drive shaft (30) is rotated while coupled to the hole (41a), the rotating tube (40) rotates together.

[0045] As illustrated in FIGS. 10 and 11, the above-described pivoting arm (50) comprises: an arm body (51) that extends in the front-rear direction and has an opening (51a) formed in the central part extending in the front-rear direction to penetrate the upper and lower surfaces, and front-rear communication holes (51b, 51c) formed on the front and rear surfaces that are connected to the opening (51a); a screw shaft (52) that is coupled to penetrate the front-rear communication holes (51b, 51c) of the arm body (51) and has a head part (52a) formed at the front end; a support block (53) that is coupled to the middle part of the screw shaft (52) to be positioned inside the opening (51a) and has the slide block (60) rotatably coupled to the upper surface, and a through hole (53a) formed to penetrate the front and rear surfaces through which the screw shaft (52) passes, and between the head part (52a) of the screw shaft (52) and the front surface of the arm body (51). It is composed of a pressure spring (54) that is coupled to the outer side of the screw shaft (52) to be positioned and presses the screw shaft (52) forward.

[0046] The above screw shaft (52) has a hexagonal wrench groove (52c) formed in the head portion (52a) to allow a hexagonal wrench to be attached.

[0047] When the screw shaft (52) is screw-coupled to the through hole (53a) of the support block (53) and rotates in the forward and reverse directions, the support block (53) slides in the forward and backward directions along the opening (51a).

[0048] Additionally, a plurality of coupling grooves (51d) are concavely formed on the front surface of the opening (51a) and located around the rear end of the front communication hole (51b), and a protruding piece (52b) that is coupled to the coupling grooves (51d) is formed on the outer surface of the middle portion of the screw shaft (52).

[0049] The above coupling grooves (51d) are composed of four and are formed at a 90-degree angle apart from the rear end of the front communication hole (51b).

[0050] The above protruding piece (52b) consists of one piece.

[0051] Accordingly, normally, the screw shaft (52) slides forward by the pressure spring (54), and accordingly, the protruding piece (52b) is coupled to the coupling groove (51d) so that the screw shaft (52) is fixed so that it does not rotate.

[0052] And, as shown in FIG. 12, when a user presses the screw shaft (52) backward by attaching a hexagonal wrench to the wrench groove (52c) of the screw shaft (52) or pushes the screw shaft (52) backward by hand, the screw shaft (52) slides backward and the protruding piece (52b) is disengaged from the coupling groove (51d), thereby releasing the fixation of the screw shaft (52). Accordingly, the user can rotate the screw shaft (52) to adjust the position of the support block (53) and the slide block (60) in the forward and backward directions.

[0053] The above slide block (60) is rotatably coupled to the upper surface of the support block (53) by a rotation axis provided on the lower side.

[0054] Accordingly, when the user steps on the pedal (6) while sitting on the saddle (4) to rotate the rotation shaft (5), the drive shaft (30) rotates, thereby rotating the rotating tube body (40) and the rotating arm (50) of the reciprocating drive means (A).

[0055] At this time, the pivot arm (50) is provided with a slide block (60) coupled to the upper guide (13) of the support (10), so that when the pivot arm (50) is rotated, the slide block (60) moves back and forth along the upper guide (13) while drawing a circular trajectory, and pushes the support (10) laterally so that the support (10) slides back and forth in the left and right directions while being supported by the reciprocating support means (20).

[0056] Additionally, the user can adjust the position of the support block (53) and the slide block (60) in the forward and backward directions by rotating the screw shaft (52), thereby adjusting the width of the saddle (4) reciprocating in the lateral direction when the pivot arm (50) is rotated.

[0057] For example, as shown in FIG. 13, when the pivot arm (50) is rotated while the support block (53) and the slide block (60) are retracted to the rearmost position, the saddle (4) reciprocates laterally with a width of L1.

[0058] Then, when the pivot arm (50) is rotated while the support block (53) and the slide block (60) are slid forward, the saddle (4) reciprocates laterally with a width of L2, which is narrower than L1.

[0059] According to the left-right reciprocating structure of the exercise bike saddle configured in this manner, the reciprocating support means (20) is composed of a support bracket (21) provided to extend in the front-rear direction at the top of the support bar (3), front-rear guide members (22, 23) respectively provided on the front-rear upper surface of the support bracket (21), and front-rear slide members (24, 25) coupled to the front-rear guide members (22, 23) so as to be slidable in the lateral direction, and the support member (10) is fixed to the front-rear slide members (24, 25).

[0060] Accordingly, the load applied to the saddle (4) is distributed and applied to the front and rear slide members (24, 25) and front and rear guide members (22, 23) through the support member (10), thereby improving the durability of the reciprocating support means (20) and having the advantage of not requiring frequent maintenance.

[0061] At this time, front and rear extension members (21c, 21d) with upper surfaces that are horizontal are provided at the front and rear ends of the support plate (11), and the front and rear guide members (22, 23) are fixed to the front and rear extension members (21c, 21d) with upper surfaces that are horizontal, so that the load is vertically transmitted to the front and rear guide members (22, 23) through the front and rear slide members (24, 25).

[0062] Therefore, since no twisting occurs in the front and rear guide members (22, 23), there is an advantage in that the durability of the front and rear guide members (22, 23) is further improved.

[0063] In addition, the support member (10) is composed of a support plate (11) that is inclined downward toward the rear, a fixing plate (12) that is provided on the upper part of the support plate (11) and coupled to the lower side of the saddle (4), an upper guide (13) that is provided to extend in the front-rear direction on the lower side of the support plate (11), a front support member (14) that extends upward from the upper surface of the front slide member (24) and has its upper end fixed to the front end of the support plate (11), and a rear support member (15) that is fixed to the upper surface of the rear slide member (25) and has its upper end fixed to the rear end of the support plate (11), so that the fixing plate (12) is stably fixed to the front-rear slide members (24, 25), thus having the advantage of being stably fixed to the front-rear slide members (24, 25).

[0064] In particular, the front support member (14) is configured to extend in the front-rear direction and includes a first fixing part (14a) fixed to the upper surface of the front slide member (24), a first extension part (14b) extended upward from the front end of the fixing part, a second extension part (14c) extended upwardly inclined from the upper end of the first extension part (14b), and a second fixing part (14d) extended backward from the upper end of the second extension part (14c) to be parallel to the support plate (11) and fixed to the upper surface of the front end of the support plate (11); and the rear support member (15) is configured to extend in the lateral direction and is configured to include a fixing part fixed to the upper surface of the rear slide member (25), a vertical part (3b) extended upward from both ends of the fixing part, and an extension part extended in an adjacent direction from the upper end of the vertical part (3b) and fixed to the lower surface of the support plate (11). There is an advantage in that sufficient space can be secured for the rotating arm (50) to rotate.

[0065] In addition, the above-mentioned pivot arm (50) is normally fixed so that the protruding piece (52b) of the screw shaft (52) is coupled to the coupling groove (51d) of the arm body (51) so that the screw shaft (52) does not rotate, and the screw shaft (52) can be pushed backward to release the coupling between the protruding piece (52b) and the coupling groove (51d), and the screw shaft (52) can be rotated to slide in the forward and backward directions of the support block (53) and the slide block (60) to adjust the position.

[0066] Therefore, there is an advantage in that the screw shaft (52) rotates on its own due to an impact that occurs during use, thereby preventing the position of the support block (53) and the slide block (60) from changing.

[0067] And, the support bar (3) is connected so as not to rotate while moving up and down inside the guide tube (2), and the rotating tube (40) is composed of a circular tube, and a blocking plate (41) with a hexagonal hole (41a) formed in the center is provided at the bottom, and the drive shaft (30) is formed in a hexagonal rod shape with a pointed top that corresponds to the hole (41a).

[0068] Therefore, when the support bar (3) and the saddle (4) are separated to store or maintain the exercise bike and then reattached to the guide tube (2), the drive shaft (30) is easily connected to the hole (41a) of the blocking plate (41), which has the advantage of making it easy to connect the support bar (3).

[0069] In the above-described embodiment, the front and rear guide members (22, 23) utilize LM guides, and the front and rear slide members (24, 25) are configured in a block shape with a shorter lateral width compared to the front and rear guide members (22, 23), and are coupled to the upper side of the front and rear guide members (22, 23) such that the upper surface is horizontal; however, as shown in FIG. 14, it is also possible to configure the front and rear guide members (22, 23) in a short block shape and configure the front and rear slide members (24, 25) as LM guides.

[0070] Also, although the guide tube (2) and support bar (3) are exemplified as being configured in a square tube shape, the guide tube (2) and support bar (3) can be configured in an elliptical shape or various other shapes.

[0071] Additionally, although the above coupling groove (51d) is exemplified as being composed of 4, the number of the above coupling groove (51d) can be varied.

[0072] Additionally, although the screw shaft (52) provided in the above-mentioned pivot arm (50) is exemplified as being able to manually rotate the user to adjust the position of the support block (53) and thereby adjust the width of the saddle (4) reciprocating laterally when the above-mentioned pivot arm (50) is rotated, it can be configured to automatically adjust the width of the saddle (4) reciprocating laterally when the above-mentioned pivot arm (50) is rotated by connecting a separate motor to the above-mentioned screw shaft (52) and using a remote control connected to the motor to rotate the motor in forward and reverse directions to automatically rotate the screw shaft (52).

[0073] FIGS. 15 to 17 illustrate a second embodiment according to the present invention, wherein the pivot arm (50) is extended in the front-rear direction, and the arm body (55) has an opening (55a) formed in the central part that extends in the front-rear direction and penetrates the upper and lower surfaces, and an extension hole (55b) formed on one side that extends in the front-rear direction and penetrates the inner and outer sides; the guide bar (56) is provided to extend in the front-rear direction inside the opening (55a) of the arm body (55), and on one side, a plurality of coupling grooves (56a) are formed to be spaced apart from each other in the front-rear direction; the support block (57) has a through hole (57a) formed to penetrate the front-rear surface through which the guide bar (56) passes, is slidably coupled to the outer side of the guide bar (56) in the front-rear direction, and the slide block (60) is rotatably coupled to the upper surface, and one end is coupled to one side of the support block (57), and the other end is through the extension hole (55b). It consists of a fixing rod (58) that extends outwardly from the arm body (55) and is elastically coupled to the coupling groove (56a).

[0074] The above guide bar (56) is configured in the shape of a square bar.

[0075] The through hole (57a) of the support block (57) is configured in the shape of a square hole corresponding to the guide bar (56), so that the support block (57) is coupled to the outside of the guide bar (56) so that it can slide but cannot rotate.

[0076] At this time, a communication hole (57b) is formed on one side of the support block (57) and opens to the through hole (57a), and the fixing rod (58) is connected to the communication hole (57b).

[0077] And, a spring (58b) that presses the fixed rod (58) inward is connected to the fixed rod (58).

[0078] To this end, the opening (57c) of the outer end of the communication hole (57b) is configured to be narrow, and a flange portion (58a) is formed in the middle part of the fixing rod (58).

[0079] And, the spring (58b) uses a compression coil spring that is coupled to the outside of the fixing rod (58) so that the front end is in close contact with the flange part (58a) and the rear end is inserted into the inside of the communication hole (57b).

[0080] Accordingly, normally, the fixed rod (58) advances by the spring (58b) and the tip of the fixed rod (58) is coupled to the coupling groove (56a) of the guide bar (56), thereby fixing the support block (57) and the slide block (60).

[0081] And, as illustrated in FIG. 17, when a user pulls the fixed rod (58) outward with their hand, the fixedness of the support block (57) and the slide block (60) is released, and by pushing the fixed rod (58) in the forward and backward directions to adjust the position of the support block (57) and the slide block (60), the width of the lateral reciprocating motion of the saddle (4) and the support (10) can be adjusted when the pivot arm (50) is rotated.

[0082] The left-right reciprocating structure of the exercise bike saddle configured in this way allows the user to adjust the position of the support block (57) and the slide block (60) by holding the fixed rod (58) with their hand, and thus has the advantage of making it easier to adjust the position of the support block (57) and the slide block (60) compared to the first embodiment described above, in which the position of the support block (53) and the slide block (60) is adjusted by rotating the screw shaft (52).

[0083] In the present embodiment, the guide bar (56) is exemplified as being configured in the shape of a square bar, but the shape of the guide bar (56) can be configured in a round bar or various other shapes.

[0084] FIGS. 18 to 20 illustrate a third embodiment according to the present invention, wherein the pivoting arm (50) is configured in the same manner as the second embodiment described above.

[0085] And, on one side of the circumference of the support block (57), a support tube (57d) connected to the communication hole (57b) is provided, and the fixing rod (58) is slidably coupled inside the support tube (57d).

[0086] At this time, a connecting hole (57e) is formed on one side of the support tube (57d) to penetrate the inner and outer surfaces, and a rack gear row (58c) corresponding to the connecting hole (57e) is formed on one side of the fixing rod (58) to extend in the front and rear directions.

[0087] And, a pinion gear (59) is coupled to the above connecting hole (57e) so as to be rotatable in the forward and backward directions, with the circumference engaging with the above rack gear row (58c) and one side having a lever (59a) extended outwardly.

[0088] At this time, the pinion gear (59) is positioned so that the lever (59a) extends laterally while the fixed rod (58) is coupled to the coupling groove (56a) of the guide bar (56).

[0089] Accordingly, under normal circumstances, the fixing rod (58) is coupled to the coupling groove (56a) of the guide bar (56) by the elasticity of the spring (58b), thereby fixing the support block (57) and the slide block (60) so that they do not move.

[0090] And, as illustrated in FIG. 20, when the user pushes the lever (59a) forward with their hand to rotate the pinion gear (59), the fixing rod (58) is retracted outward to release the fixation of the support block (57), and the user can adjust the position of the support block (57) by holding the lever (59a) and the support tube (57d) and pushing the support block (57) sideways.

[0091] According to the left-right reciprocating structure of the exercise bike saddle configured in this way, a support tube (57d) is provided on one side of the support block (57), and the fixing rod (58) is provided inside the support tube (57d), so that when the user rotates the lever (59a), the support tube (57d) moves back and forth.

[0092] Accordingly, since the user can slide the support block (57) in the forward and backward directions while holding the support tube (57d) with the lever (59a) rotated, it is easier to release the fixation of the support block (57) compared to the second embodiment described above, in which the user can move the support block (57) forward and backward by pushing the fixation rod (58) while pulling the fixation rod (58). Furthermore, since the fixation rod (58) is protected by the support tube (57d), there is an advantage in that the fixation rod (58) can be prevented from being damaged when the user moves the support block (57) forward and backward.

[0093] FIG. 21 illustrates a fourth embodiment according to the present invention, wherein the guide tube (2) is provided to be inclined upward toward the rear.

[0094] And, the support bar (3) is composed of an inclined portion (3a) that extends upwardly toward the rear and is slidably coupled to the guide tube (2), and a vertical portion (3b) that extends upward from the top of the inclined portion (3a).

[0095] Additionally, the rotating tube (40) is composed of a lower tube (42) which is rotatably coupled to the interior of the inclined portion (3a) and whose lower end is coupled to the drive shaft (30), and an upper tube (43) which is rotatably coupled to the interior of the vertical portion (3b), whose lower end is dynamically connected to the lower tube (42) and whose upper end is coupled to the rotating arm (50).

[0096] At this time, the lower tube (42) and the upper tube (43) are interconnected by a bevel gear (44) provided at an adjacent end, so that when the lower tube (42) is rotated, the upper tube (43) is configured to rotate in the same direction.

[0097] And, the support bracket (21) is coupled to extend horizontally to the upper end of the vertical portion (3b) of the support bar (3), and the front and rear guide members (22, 23) are provided so that their upper surfaces are horizontal on the upper surfaces of the front and rear ends of the support bracket (21).

[0098] According to the left-right reciprocating structure of the exercise bike saddle configured in this manner, since the upper end of the support bar (3) is extended in a vertical direction, unlike the previously described embodiment in which the upper end of the support bar (3) is positioned at an angle, the support bracket (21) and the rotational driving means can be positioned horizontally, and it becomes easy to position the front and rear guide members (22, 23) horizontally at the same height on the upper surface of the front and rear ends of the support bracket (21).

[0099] Accordingly, the load applied to the saddle (4) is stably transmitted to the front and rear guide members (22, 23), which has the advantage of improving the durability of the front and rear guide members (22, 23).

[0100] In the present embodiment, the lower tube (42) and the upper tube (43) are shown to be interconnected by a bevel gear, but the lower tube (42) and the upper tube (43) may be configured to be interconnected using a universal joint or a ball joint.

[0101] FIG. 22 illustrates a fifth embodiment according to the present invention, wherein the guide tube (2) is provided to extend vertically behind the rotation axis (5).

[0102] And, the drive shaft (30) is drivenly connected to the rotation shaft (5) by a connecting shaft (31) that extends in the front and rear directions.

[0103] The above connecting shaft (31) is equipped with bevel gears at its front and rear ends, and the front and rear ends are respectively connected to the rotation shaft (5) and the drive shaft (30) through the bevel gears.

[0104] And, the support bracket (21) is coupled to extend horizontally to the upper end of the vertical portion (3b) of the support bar (3), and the front and rear guide members (22, 23) are provided so that their upper surfaces are horizontal on the upper surfaces of the front and rear ends of the support bracket (21).

[0105] According to the left-right reciprocating structure of the exercise bike saddle configured in this way, since the support bar (3) is extended vertically, unlike the previously described embodiment in which the upper end of the support bar (3) is positioned at an angle, the support bracket (21) and the rotational driving means can be positioned horizontally, and it becomes easy to position the front and rear guide members (22, 23) horizontally at the same height on the upper surface of the front and rear ends of the support bracket (21).

[0106] In particular, unlike the aforementioned fourth embodiment in which only the upper portions of the guide tube (2) and the rotating tube (40) are arranged vertically, the entire guide tube (2) and the rotating tube (40) are arranged vertically, so there is an advantage of a simple structure and improved strength.
