Problems to be solved by the utility model

However, even if some structures are integrated, the volume of such exercise equipment is still too large, and even if the exercise equipment is put into an ordinary household with ease, it takes up too much room. In particular, home-use exercise equipment is not as high as gym-use exercise equipment, and when the exercise equipment is not needed, it is required to be placed in a place that does not interfere with the overall environment of the home, for which ordinary households often cannot prepare dedicated storage space, and exercise equipment is often quite ill-suited to other home decorations and furniture, and there is a problem of wasted space and unsightly appearance even if the exercise equipment is stored barely.

In addition, in the pedal portion on which the exerciser steps, there is a need to use pedals having different friction coefficients according to the exercise program or the requirement of the exerciser, and in particular, since the pedals are very frequently used components, maintenance such as cleaning and the like are required to be frequently performed, and replacement is required to be performed, but the pedals of the conventional exercise apparatus are not detachably mounted on the exercise apparatus, and maintenance of the pedals is difficult and replacement thereof is impossible.

In addition, as the digital exercise equipment is put into ordinary families for use, the requirements of people on the appearance of the exercise equipment are also higher and higher, but the structure of the digital exercise equipment at the present stage is already molded and solidified, so how to reform the integral structure of the exercise equipment so that the integral structure of the exercise equipment can be improved in terms of performance and appearance is also an important subject.

Therefore, an object of the present utility model is to provide a rack for exercise equipment and exercise equipment having the same, which are suitable for use in a room of an ordinary home, are compact, can be stored in a small volume when not in use, thereby being capable of reducing the occupied space of the home, and also being convenient for maintenance and replacement of parts, and are more attractive in appearance.

As shown in fig. 1 and 2, in one embodiment of the present utility model, the exercise apparatus F mainly includes: a frame H having a main body portion 1 and a chassis portion 2; a motor provided in the interior or the rear surface of the main body 1 (for example, the side facing away from the reader in fig. 5, the right side in fig. 6); a wire spool connected with the motor and wound with a rope; a pulley block for guiding the rope to the outside of the main body 1; a handle portion (grip portion) connected to a rope led to the outside of the main body portion 1. In addition, in one example, a decorative surface, a mirror surface, a touch display screen, or the like may be provided on the front surface (i.e., the front surface, for example, the reader-side in fig. 5, the left side in fig. 6) of the main body portion 1, and a panel portion 11 described later may be provided, for example.

In addition, in other examples of the present utility model, the panel portion 11 may be a general plate material such as a general plastic plate or a high-hardness plastic or decorative plate, etc., in view of the cost of the material. However, by providing the panel portion 11 as a display panel or an operation panel (e.g., a liquid crystal display, a touch panel, a touch display, etc.), or a structure in which a display screen and an operation screen are provided on a plate material, it is possible to more facilitate the user of the exercise apparatus F to exchange an item to be exercised, read and input exercise data, control exercise conditions in real time, and the touch display screen or the like to display exercise course videos, play entertainment programs, or the like, for example. In addition to the above functions, the panel portion 11 may be formed as a mirror surface or a mirror surface display device with a display operation function, so that the user of the exercise device can observe and operate his or her exercise motion at any time. If the panel portion is formed in the shape of a mirror or a mirror display, the entire body-building apparatus F is formed in the shape of a mirror in the folded state (storage state) described later as shown in fig. 4, and the body-building apparatus F can be used as a mirror or a display device, and thus, even in a state where the body-building apparatus is not energized, the body-building apparatus F can be temporarily used as a mirror, for example, a fitting mirror, so that the body-building apparatus is not in a condition of being put into a normal house, and the overall beauty of a room is not impaired. In one example, the panel portion may be set to have the same height as the main body portion, but may be set to have different heights and sizes, and is not particularly limited thereto, and for example, in the case of setting the panel portion as an electronic device such as a display, the panel portion may be provided locally on the front surface of the main body portion (that is, not the entire front surface of the main body portion but only a small-sized panel portion) in consideration of the cost of the device or the like.

Further, in one example of the present utility model, as shown in fig. 2, a motor and a spool are provided on the back surface of the main body portion 1, and a rope on the spool is connected to an exercise unit such as a grip portion or a handle portion for a user to grip via an index such as a pulley or a pulley block. However, the motor and the spool may be provided in the main body 1 as needed, and this is not particularly limited.

In addition, in one example of the present utility model, as shown in fig. 2, only one motor is used by designing the pulley block in consideration of the volume of the whole machine, and the single-head rope discharging of the single motor is converted into the double-head rope discharging of the handle end, but the present utility model is not limited thereto, and a double motor or other structures may be used as required.

For convenience of explanation, in the present utility model, the exercise apparatus F (frame H) in the state shown in fig. 5 to 7 is taken as an example, and the side of the exercise apparatus F facing the user (i.e., the side of the panel portion 11 facing the user) is referred to as "front side or front side" (the side facing the reader in fig. 5, the left side in fig. 6), and the opposite side of the "front side" is referred to as "back side or reverse side" (the opposite side of the panel portion 11 in fig. 5, i.e., the right side in fig. 6). Further, the left hand side when the user faces the exercise apparatus F is referred to as "left side" (left side in the front view of fig. 5), and the right hand side when the user faces the exercise apparatus F is referred to as "right side" (right side in the front view of fig. 5). In the state shown in fig. 5, the vertical direction is sometimes referred to as "the height direction of the exercise machine", and the horizontal direction is sometimes referred to as "the width direction of the exercise machine". In the state shown in fig. 6, the left-right direction is also sometimes referred to as "thickness direction of exercise equipment" or "depth direction of exercise equipment" or "front-rear direction of exercise equipment". In the present utility model, these descriptions of directions and orientations are merely provided for convenience in explaining the relative positional relationship between the respective components of the exercise apparatus F of the present utility model, and if the posture of the exercise apparatus F is changed, the term indicating the orientation is naturally changed accordingly.

In addition, as the resistance transmission mechanism, a planetary differential gear, a bevel gear set, or any other mechanism capable of transmitting resistance may be used, and there is no particular limitation in this regard as long as resistance generated by a motor as a resistance source can be transmitted to the spool. As shown in fig. 2, the spool may be directly attached to the motor as a resistance source without providing a resistance transmission mechanism, and this is not particularly limited.

In addition, in one embodiment of the present utility model, the frame H is capable of being converted between a collapsed state and an expanded state. Specifically, as shown in fig. 1 to 4, the main body portion 1 of the frame H is vertically disposed (e.g., perpendicular to the bottom surface or the horizontal surface), the chassis portion 2 of the frame H is rotatably connected to the main body portion 1 by a rotation shaft or a hinge or the like, and when the chassis portion 2 is rotated to a state parallel to the main body portion 1 (e.g., as shown in fig. 4 and 8 to 10, the chassis portion 2 at this time is also in a vertical state (e.g., perpendicular to the bottom surface or the horizontal surface)), this state is referred to as a "folded state (this state is also sometimes referred to as a" stored state "of the exercise apparatus F); when the chassis section 2 is rotated to a state perpendicular to the main body section 1 (for example, as shown in fig. 3 and 5 to 7, the chassis section 2 is placed horizontally on the ground), this state is referred to as "unfolded state" (this state is also sometimes referred to as "operating state" of the exercise apparatus F). Here, terms such as "vertical", "parallel", and the like do not strictly refer to absolute vertical and parallel in a geometric sense, and may be slightly offset by a certain angle, as long as they are substantially vertical or horizontal. In addition, in another embodiment of the present utility model, the frame H may be capable of being switched between the cross-folded state and the unfolded state. In this other embodiment, the unfolded state is the same as the above embodiment, and the cross folded state means that the side of the frame H crosses the vertically placed main body. This will be described in detail later.

In addition, as shown in fig. 1 and 2 and fig. 7, in the unfolded state of the frame H (in the operating state of the exercise apparatus F), a pedal portion 21 for use by an exerciser may be laid on the base frame portion 2. By laying the pedal portion 21 so that an exerciser can stand on the pedal portion 21 for training, the exerciser and the exercise apparatus at this time can be regarded as a whole, and the force between the exerciser and the exercise apparatus becomes an internal force, so that even if the exerciser applies an excessive force, the machine can be kept stable without toppling.

In the present utility model, the step portion 21 may be formed of a single piece of material (integral structure) or may be formed of a plurality of pieces of material (separate structure). The material of the pedal portion 21 is not limited, and it is preferable to use an anti-slip material or the like in view of safety of the exerciser.

In one embodiment of the present utility model, the bottom frame portion 2 is formed of a substantially rectangular pedal portion 21 and a substantially コ -shaped (or U-shaped) outer frame 22 having one end open provided around the periphery of the pedal portion 21, and the pedal portion 21 is detachable with respect to the outer frame 22. By designing in this way, it is possible to facilitate cleaning and replacement of the pedal portion 21 that is often used, to prepare different pedal portions 21 (for example, requirements for friction force, requirements for surface texture of pedal portions, and the like) for different training items, and to make the thickness of the folded exercise apparatus in the thickness direction thinner as a whole (for reasons that the thickness can be made thinner, as described later), to facilitate storage and placement of the exercise apparatus F. The rectangular shape, the コ shape (or U-shape) and the like are only examples, and other shapes are also possible.

In addition, as shown in fig. 1 and 3, the frame H further includes a locking mechanism 3, and when the frame H is in the unfolded state, the locking mechanism 3 can lock the chassis section 2 so that the chassis section 2 cannot rotate relative to the main body section 1, thereby locking the whole of the frame H in the unfolded state (the operating state of the exercise apparatus F).

As for the lock mechanism 3 of the frame H, referring to fig. 1, 3, and 11 to 14, in the present utility model, the lock mechanism 3 is mainly composed of a first lock 31 and a second lock 32. Specifically, the lock mechanism 3 includes a first lock 31 provided in the main body 1 and a second lock 32 provided in the chassis 2 and lockable to the first lock 31. Here, the positions of the first locking piece 31 and the second locking piece 32 in the present embodiment are merely illustrative, and the present utility model is not limited to this, and for example, the second locking piece 32 may be provided to the main body portion 1 and the first locking piece 31 may be provided to the chassis portion 2, so long as the first locking piece 31 and the second locking piece 32 are provided to the main body portion 1 and the chassis portion 2, respectively, and the both can be locked to each other.

In the utility model, by arranging the locking mechanism 3, when the frame H is in the unfolded state, the locking mechanism 3 can be used for locking the underframe part 2 so that the underframe part 2 can not rotate relative to the main body part 1, thereby the whole frame H and even the body-building equipment F can be kept stable, the safety of an exerciser is ensured, and good use experience can be brought to the exerciser.

More specifically, as shown in fig. 11 to 14, the first lock member 31 includes a lock lever 311, and the lock lever 311 is rotatable about one end. The manner in which the lock lever 311 can rotate is not particularly limited, and for example, the lock lever 311 may be rotated by a screw-coupling method described later, or may be freely rotated by a pin or the like, as long as the lock lever 311 can rotate about one end.

For a specific manner in which the second locking member 32 is used to lock with the first locking member 31, for example, a lock piece that can engage with the lock lever 311 may be provided in the second locking member 32. As an example of the lock piece, for example, a wedge 321 may be used as the lock piece, that is, a wedge 321 that can be engaged with the lock lever 311 may be provided in the second lock piece 32. At this time, in a state where the underframe 3 is horizontally placed on the ground (horizontal plane) (i.e., in an expanded state of the frame H), the wedge 321 has a wedge surface 322 inclined with respect to the horizontal plane (the end of the wedge surface 322 in this state having a high height is sometimes referred to as a high end of the wedge surface, and the end having a low height is sometimes referred to as a low end of the wedge surface).

Further, as shown in fig. 12, when the frame H is in the unfolded state in which the chassis section 2 is perpendicular to the main body section 1 and horizontally placed on the ground, the lock lever 311 can be rotated to a position where it abuts against the wedge surface 322 of the wedge 321 (counterclockwise rotation as shown by an arrow in fig. 12) and can be moved along the wedge surface 322 of the wedge 321 from the lower end of the wedge surface 322 to the upper end of the wedge surface 322 with further rotation of the lock lever 311, and engagement between the lock lever 311 and the wedge 321 is achieved by the wedge structure, whereby mutual locking of the first locking piece 31 with respect to the second locking piece 32 can be achieved, and the frame H can be maintained in the unfolded state for exercise by the exerciser.

Here, the lower end and the upper end of the wedge surface 322 refer to the structural height of the wedge 321. Specifically, as shown in fig. 6, when the chassis section 2 is placed vertically to the main body section 1 and horizontally on the ground, the left side of the wedge surface 322 of the wedge 321 is a high end, and the right side of the wedge surface 322 of the wedge 321 is a low end, that is, the wedge surface 322 is a slope inclined to be high and low on the left side with respect to the horizontal plane in the view shown in fig. 6. By providing this, in the process that the lock lever 311 is moved from the lower end of the wedge surface 322 to the upper end of the wedge surface 322 along the wedge surface 322, the lock lever 311 applies a downward pressing force to the wedge surface 322 (the wedge 321) to engage the lock lever 311 with the wedge 321, and thus the first locking piece 31 and the second locking piece 32 can be locked to each other. That is, in the present utility model, the main body portion 1 and the chassis portion 2 can be locked by a simple wedge structure, and the chassis H can be locked in the unfolded state.

When the lock between the main body 1 and the chassis 2 is released to allow the chassis H to be converted into the folded state, the lock lever 311 is rotated in the opposite direction. Specifically, as shown in fig. 13, by rotating the lock lever 311 clockwise to move from the upper end of the wedge surface 322 to the lower end of the wedge surface 322, the lock lever 311 can be released from the pressing engagement with the wedge block 321, and by further rotating the lock lever 311 clockwise to a position not interfering with the chassis 2 (for example, rotating the lock lever 311 to a position substantially parallel to the side of the chassis 2 in fig. 13), the mutual locking between the main body 1 and the chassis 2 can be achieved. At this time, the chassis section 2 is rotatable with respect to the main body section 1, and when the frame H is required to be folded, the chassis section 2 is required to be rotated upward in fig. 3.

By the locking mechanism of the present utility model, the transition between the folded state and the unfolded state of the chassis H can be achieved with a simple structure, and by providing the wedge structure, a large pressing force (locking force) can be obtained in a simple manner, without providing additional locking members and without worrying about occurrence of unstable locking. Further, since the locking mechanism adopts a wedge structure of the lock lever and the wedge, both the locking operation and the unlocking operation of the lock lever 311 are one-way operations (for example, as shown in fig. 12 and 13, the lock lever 311 is operated counterclockwise when locking and the lock lever 311 is operated clockwise when unlocking), so that erroneous operations can be prevented, safety is improved, and the exerciser can firmly lock the frame H in the unfolded state with a small force.

As an example of the installation lock lever 311 of the present utility model, as shown in fig. 14, the first lock member 31 may further have a rotatable shaft 312, and an L-shaped lock handle S may be formed by connecting one end of the shaft 312 to one end of the lock lever 311. The lock lever 311 and the shaft 312 may be integrally formed, that is, may integrally form an L-shaped locking handle S. In the present utility model, as shown in fig. 11, the other end of the shaft 312 is fitted into the fitting hole 313 provided in the main body 1, whereby the lock lever 311 can be rotatably provided in the main body 1 by a simple structure, and the lock lever 311 and the shaft 312 at this time can be unlocked and locked as a locking handle S as a whole.

In addition, in one embodiment of the present utility model, a screw portion 314 that can be screwed in and out with respect to the mounting hole 313 is further provided at the other end (lower end of fig. 11) of the shaft 312. At this time, a screw capable of engaging with the screw portion 314 is provided in the mounting hole 313. Alternatively, the shaft 312 may be integrally formed as a threaded rod.

In addition, regarding the relationship between the screwing in/out of the screw portion 314 of the shaft 312 with respect to the mounting hole 313 and the rotation of the lock lever 311, it is further possible to make the following by adjustment: when the lock lever 311 moves along the wedge surface 322 of the wedge 321 from the lower end of the wedge surface 322 to the upper end of the wedge surface 322, the screw portion 314 of the shaft 312 moves in the direction of screwing into the mounting hole 313; when the lock lever 311 moves along the wedge surface 322 of the wedge 321 from the high end of the wedge surface 322 to the low end of the wedge surface 322, the threaded portion 314 of the shaft 312 moves in a direction of screwing out the mounting hole 313.

By thus providing the relationship between the screwing in/out of the screw portion 314 with respect to the mounting hole 313 and the rotation of the lock lever 311, as shown in fig. 12, when the lock lever 311 is rotated counterclockwise to move the lock lever 311 along the wedge surface 322 of the wedge 321 from the lower end of the wedge surface 322 to the upper end of the wedge surface 322, since the screw portion 314 of the shaft 312 is moved toward the direction of screwing in the mounting hole 313, an exerciser can press the wedge block 321 by the shaft 312 with a small force, and can lock the main body portion 1 and the base frame portion 2 in the expanded state more firmly, so that the frame H can be held in the expanded state more stably.

In another embodiment of the present utility model, a coil spring which is always kept in a stretched state may be provided around the shaft 312 between the connection end of the lock lever 311 and the shaft 312 and the bottom surface of the mounting hole 313, instead of providing a screw portion in the lock lever 311. By providing the coil spring in this way, in the locked state of the main body portion 1 and the chassis portion 2, since the coil spring is always kept in the stretched state, the lock lever 311 is always pulled downward by the coil spring, so that the lock lever 311 can be always kept pressing down the wedge 321, so that the lock lever 311 can be always brought into close contact with the fixture surface when the lock lever 311 is not operated, locking in the unfolded state can be automatically achieved, and locking of the main body portion 1 and the chassis portion 2 in the unfolded state can be made more firm. Further, a coil spring which is always kept in a stretched state may be provided between the bottom end of the lock lever 311 and the bottom surface of the mounting hole 313, as long as the coil spring is always kept in a stretched state so as to be able to pull the lock lever 311 downward.

In another embodiment of the lock block of the present utility model, instead of providing the wedge block in the second lock piece 32, an engagement block capable of engaging with the lock lever 311 may be provided in the second lock piece 32, and a substantially horizontal abutment surface capable of abutting with the lock lever 311 may be provided on the surface of the engagement block. That is, the engagement block is used as the lock block of the present utility model, and the abutment surface of the engagement block is not inclined like the wedge surface of the wedge but is kept horizontal. In this case, the engagement block may be provided with a locking groove or the like into which the lock lever 311 can be fitted. By this arrangement, when the chassis H is in the unfolded state in which the chassis portion 2 is perpendicular to the main body portion 1 and is placed horizontally on the ground, the lock lever 311 can be rotated to a position where it abuts against the surface of the engagement block, and can be engaged with the engagement block by being fitted into the engagement groove with further rotation of the lock lever 311, whereby the main body portion 1 and the chassis portion 2 can be locked in the unfolded state. In addition, in order to facilitate the lock lever 311 to be better engaged into the engagement groove of the engagement block, the lock lever 311 may be set to have elasticity. In addition, a coil spring that is always kept in a stretched state may be provided between the connection end of the lock lever 311 and the shaft 312 or between the bottom end of the lock lever 311 and the bottom surface of the mounting hole 313. At this time, since the abutment surface is substantially horizontal and has no level difference, compared with the case where the beveled wedge is provided, the exercise apparatus can be locked and unlocked from both directions (clockwise or counterclockwise), and the exerciser can operate more conveniently.

In other embodiments of the present utility model, for example, as shown in fig. 11, a lock protrusion 315 may be provided at a portion of the lock lever 311 that abuts against the wedge surface 322, and a lock hole 323 capable of locking with the lock protrusion 315 may be provided on a surface of the wedge surface 322. By providing the locking protrusion 315 and the locking hole 323, when the locking protrusion 315 of the lock lever 311 reaches the locking hole 323 as the lock lever 311 rotates, the locking protrusion 315 can be automatically and accurately fitted into the locking hole 323, so that locking can be more accurately performed, and since the locking protrusion 315 is less likely to slide out of the locking hole 323, locking of the main body portion 1 and the chassis portion 2 in the unfolded state can be more firmly performed. In addition, when the engagement block is provided instead of the wedge, a locking hole may be provided in the engagement groove of the engagement block.

Further, regarding the specific structure of the underframe portion 2, in one embodiment of the present utility model, for example, as shown in fig. 1 to 7, the underframe portion 2 is formed of a substantially rectangular pedal portion 21 and a substantially コ -shaped (or U-shaped) outer frame 22 provided around the periphery of the pedal portion 21 and having one end open. The chassis section 2 further has a hollow portion 23 for mounting the pedal section 21. Specifically, the middle portion of the chassis section 2 is hollowed out, and the remaining portion forms the outer frame 22, and the hollowed-out portion becomes the hollow portion 23. In other words, the outer frame 22 is a frame body in which the middle portion is hollowed out, and the hollow portion 23 is surrounded by the outer frame 22, and is used as an installation space for installing the pedal portion 21. Furthermore, it is possible to provide a device for the treatment of a disease. The pedal portion 21 is detachable from the outer frame 22.

The main body 1 is preferably constituted by a rectangular panel 11 and a base 12 provided below the panel 11, but the present utility model is not limited to this, and the base 12 may not be provided. In the illustrated embodiment, the open end of the generally コ -shaped housing 22 is rotatably connected to the base 12 (referring to fig. 3, the left end of the generally コ -shaped housing 22 is pivotally or hingeably connected to the base 12). In one embodiment, the first locking member 31 is provided on the base 12 and the second locking member 32 is provided on the outer frame 22, but the present utility model is not limited thereto, and the first locking member 31 may be provided on the outer frame 22 and the second locking member 32 may be provided on the base 12.

By making the step part 21 detachable from the outer frame 22, in a state where the step part 21 is detached and in a folded state of the frame H, as shown in fig. 4, the hollow part 23 of the chassis part 2 is not shielded by the step part 21, so that the panel part 11 of the main body part 1 can be exposed through the hollow part 23, and the exercise apparatus can be temporarily used as a mirror even in a non-energized state, so that the exercise apparatus is not seen as a normal house because the exterior (front) is in a mirror state, for example, and the overall aesthetic appearance of the room is not spoiled as compared with a normal house apparatus.

The above description is only one embodiment of the present utility model, and in other embodiments of the present utility model, the area of the hollow portion 23 (the area where the pedal portion is laid/the area where the middle of the chassis portion is hollowed out) may be further made not smaller than the area of the panel portion 11 so as to be able to cover the panel portion entirely. By providing such a configuration, when the chassis H is in the folded state in a state where the pedal portion 21 is detached from the outer frame 22, the panel portion 11 can be completely exposed through the hollow space of the hollow portion 23 when viewed from the front. Here, the larger area of one than the other means that the area of one is large enough to cover the other, for example, in the case where both the hollow portion 23 and the panel portion 11 are rectangular, the area of the hollow portion 23 is not smaller than the area of the panel portion 11 means that neither the length nor the width of the hollow portion 23 is smaller than the length and the width of the panel portion 11.

More specifically, the machine is switched between a folded state in which the chassis section 2 is parallel to the main body section 1 and an unfolded state in which the chassis section 2 is perpendicular to the main body section 1 and is placed horizontally on the ground by rotation of the chassis section 2, and may be such that the whole of the outer frame 22 is positioned in front of the main body section 1 when viewed from the side in the folded state; or in a folded state, at least a part of the main body portion 1 is located in the hollow portion 23 when viewed from the side; or in a folded state, the front surface of the outer frame 22 is flush with the front surface of the panel part 11 in the same vertical plane as viewed from the side; or in a folded state, the whole of the outer frame 22 is located behind the main body 1 when viewed from the side. That is, since the panel portion 11 can be seen through the hollow portion 23 entirely when viewed from the front, the outer frame 22 does not interfere with the panel portion 11, i.e., a person standing in front of the exercise apparatus F does not interfere with the panel portion 11, and the outer frame 22 surrounds the periphery of the panel portion 11 as if it were a mirror frame (the inner peripheral surface of the outer frame 22 may be a predetermined distance from the panel portion 11), regardless of whether the outer frame 22 is positioned in front of the main body portion 1, the outer frame 22 overlaps the main body portion 1, or the outer frame 22 is positioned behind the main body portion 1. At this time, by providing the panel part 11 as a decorative plate or a touch display panel or a display panel in the storage state of the exercise apparatus, since the content of the panel part 11 can be displayed entirely, the exercise apparatus F is more beautiful as a whole, can be placed in the living space of an ordinary household without being excessively in contact with surrounding furniture appliances or the like, and also can play a role in beautifying the home environment, especially when the panel part 11 is provided as a touch display panel or a display panel, even if the exercise apparatus F is held up by hand, it can be used as a display screen in the energized state, and does not cause shielding to the screen.

In a preferred embodiment, the connecting shaft (for example, hinge shaft) between the main body 1 and the chassis 2 is positioned on the same general line as the side edge of the panel 11 in the vertical direction in a side view (see fig. 6), and the arrangement is such that the main body 1 in the folded state is positioned just inside the hollow portion 23 and at least a part of the main body 1 in the side view overlaps the outer frame 22 (see fig. 4 and 6), that is, at least a part of the main body 1 is positioned inside the hollow portion 23 when viewed from the side in the folded state. At this time, the front surface of the outer frame 22 is further flush with the front surface of the panel portion 1 and is positioned in the same vertical plane, so that when the frame H is in the folded state, the front surface of the outer frame 22 (actually, the bottom surface of the outer frame 22 in the unfolded state, which is in contact with the bottom surface, of the frame H) and the front surface of the panel portion 11 are positioned substantially in the same vertical plane when viewed from the front, and the outer frame 22 of the frame H in the folded state and the panel portion 11 are visually brought into a substantially integrated state (when viewed from the side, there is no difference in height between the outer frame 22 and the panel portion 11), whereby the thickness of the exercise apparatus after folding in the thickness direction can be made thinner and more beautiful as a whole.

In addition, by providing the step portion 21 so as to be detachable from the outer frame 22 in this way, the exposure of the ground contact portion in the unfolded state can be reduced, and the whole body of the exercise apparatus F can be more beautiful in the housed state. Specifically, the outer frame 22 and the pedal portion 21 are usually required to be laid on the ground, and in view of factors such as friction and safety, special treatments such as anti-slip treatment are usually required to be performed on the portions of the outer frame 22 and the pedal portion 21 that contact the ground, and special members or the like are sometimes required to be provided on the surfaces that contact the ground, so that these portions that contact the ground are often not compatible with the beauty, and when the frame is in the folded state, these surfaces that originally contact the ground are exposed to the front of the user, which may seriously affect the beauty of the exercise apparatus in the stored state. Further, in order to avoid the need to shorten the length of the step portion in the stored state without blocking the panel portion, a sufficient length of the step portion may not be ensured, and if the step portion is made sufficiently long, the overall size of the exercise apparatus further increases, and even the exercise apparatus may not be stored in a room of an ordinary household. In this regard, the present utility model is capable of making the whole body of the exercise apparatus more beautiful by providing the pedal portion 21 to be detachable with respect to the outer frame 22 so that only the portion of the outer frame 22 that contacts the ground is exposed to face the user in the housed state of the exercise apparatus, and the outer frame 22 is present in a manner similar to a "mirror frame" so as not to draw much attention of people, and the outer frame 22 occupies only a small portion of the front face of the exercise apparatus in the housed state.

In addition, the present utility model is not limited to this, and for example, when an electronic device such as a touch panel or a liquid crystal display is used as the panel portion, the panel portion may be provided only in a part of the front surface of the main body portion in view of cost, for example, a small panel portion may be provided at an upper position of the front surface of the main body portion (the height of the panel portion is smaller than that of the main body portion), and in this case, the chassis portion may be provided such that the top end of the chassis portion and the bottom end of the panel portion are located at the same height when viewed from the side in a folded state, or the top end of the chassis portion is located further below the bottom end of the panel portion. That is, the length of the chassis section can be set to be short as compared with the previous embodiment. By the arrangement, the optimization of the appearance and the reduction of the volume are realized on the premise of reducing the cost of the exercise equipment.

In the above description, the case where the chassis H can be switched between the folded state in which the chassis section 2 (the outer frame 22) is parallel to the main body section 1 and the unfolded state in which the chassis section 2 (the outer frame 22) is perpendicular to the main body section 1 and horizontally placed on the ground by the rotation of the chassis section 2 has been described as an example, but the present utility model is not limited to this, and the chassis H may be switched between the cross folded state in which the outer frame 22 crosses the main body section 1 and the unfolded state in which the chassis section 2 (the outer frame 22) is perpendicular to the main body section 1 and horizontally placed on the ground by the rotation of the chassis section 2. Specifically, in this embodiment, the base 12 is provided below the main body 1 as well, and the outer frame 22 is rotatably attached to the base 12 as well, but the connection position of the outer frame 22 and the base 12 is located rearward of the connection position of the main body 1 and the base 12 when viewed from the side. In other words, the connection position of the outer frame 22 and the base 12 is located further rearward than the connection position of the main body portion 1 and the base 12 for the exerciser facing the exercise apparatus F (in the above embodiment, the connection position of the outer frame 22 and the base 12 is located further forward than the connection position of the main body portion 1 and the base 12 for the exerciser facing the exercise apparatus F, or the distance between them and the exerciser facing the exercise apparatus F is equal). At this time, the front surface of the main body 1 is also provided with the panel 11, and the frame H can be switched between a cross-folded state in which the outer frame 22 crosses the main body 1 by rotation of the chassis 2, and an unfolded state in which the chassis 2 is placed vertically to the main body 1 and horizontally on the ground, and in the cross-folded state, when viewed from the side, the side edge of the outer frame 22 crosses the vertically placed main body 1, and the tip of the outer frame 22 is located in front of the panel 11 (closer to the exerciser) or at the position where the tip of the panel 11 is located (approximately equal distance from the exerciser). By designing in this way, in the cross-folded state, since the front surface of the panel portion 11 is also not shielded (the step portion is detached from the outer frame 22), the panel portion 11 can be exposed toward the front as well, and the whole body of the exercise apparatus can be made more beautiful. In this case, as compared with the above-described embodiment, the whole (or most) of the panel portion 11 can be exposed forward without shielding as compared with the panel portion 11 having the same height, and the present embodiment can make the length of the portion of the outer frame in the expanded state for placing the pedal portion in the front-rear direction shorter, which is advantageous for users or exercise items requiring a low length of the pedal portion, and is advantageous for placement in a narrow space because the floor space of the equipment in the expanded state can be relatively reduced without reducing the height of the panel portion.

While the embodiments of the present utility model have been described, those skilled in the art can make various modifications and alterations to the embodiments of the present utility model without departing from the spirit and scope of the utility model.
