Abstract

The present invention provides a kind of exercise equipment and a pedal assembly thereof. The pedal assembly is mounted, one the left side and one for the right side, to the portions of the exercise equipment that guide the feet of a user to carry out reciprocal motion. Each pedal assembly has a support face that allows a single foot of the user to step thereon. The support face, in entirety, exhibits a shape that extends horizontally in the width direction but is gradually bulged from two opposite ends toward the center area in the length direction. The center area functions to support a middle section of sole between toe end and heel end. The support face, when bearing the weight of the user, can still maintain the aforementioned shape as a whole. As such, in each position along the foot movement path, at least the center area of the support face of the pedal will continuously support at least the middle section of sole to avoid load concentration at toe or heel.

Description

Sports equipment and pedal components for sports equipment

The present invention relates to sports equipment, and more particularly to a sports apparatus for reversing movement of a user's feet with two left and right pedals, and a pedal assembly for the aforementioned sports equipment.

In the field of sports equipment, there are many sports equipments that can guide the user's feet with the left and right pedals, and the most typical ones should be called a bicycle, except for the bicycles that most people are familiar with. A common feature of such sports equipment is that it has left and right positions that can maintain relative motion, as disclosed in U.S. Patent Nos. 5,540,637, 5,685,804, 6,689,019. The two pedals are used for the user to step on the foot and apply force. Each pedal supports the user's sole to circulate along a fixed, adjustable or elliptical closed trajectory that can change with the force applied. Guide the user's legs to perform actions like walking or running.

When the pedal of the aforementioned elliptical exercise machine performs a cyclic motion, the longitudinal direction of the pedal (refer to the direction of connection corresponding to the tip end of the user's foot and the heel end) with respect to the ground is generally cyclically changed in the same cycle. For example, most of the current elliptical exercise machines are designed such that when the pedal moves to the bottom of the closed trajectory, the support surface (substantially a plane) of the pedal for the user to step on is substantially horizontal, and as the pedal gradually becomes Ascending, the aforementioned support surface will gradually slant forward, and when the pedal is lowered from the top of the closed trajectory, the support surface will gradually become horizontal. The designer of the elliptical exercise machine usually appropriately sets the angle change of the pedal support surface during the entire movement stroke based on ergonomics, so that the user can perform the leg movement naturally and comfortably.

However, the angle of the pedal support surface predetermined by the designer is, at best, theoretically suitable for most people's angles. However, in reality, different users may be involved in the circulation of the foot due to factors such as body shape, posture, and habits. There will be (or want to have) a slightly larger or slightly smaller foot angle. That is to say, the angle of the predetermined support surface of the pedal at a certain position on the closed trajectory or a certain section may be generally appropriate and comfortable for the user A, but appears to the user B as the back end. Low, the slope is too small, and at the same time, for the user C, the back end is too high and the slope is too large. Since the conventional pedal supporting surface is substantially a flat surface, in the above situation, the rear end portion of the user's sole (usually referred to as the sole, the same below) will float more or less from the supporting surface, and only The front end portion of the sole of the foot is pressed downward against the support surface, or the front end portion of the sole of the foot is supported by the support surface, so that the foot load is concentrated on the tip of the foot; otherwise, the user C may feel that the step is gradually thicker. On the wedge, because the sole of the foot wants to step down, it tends to press the support surface at the rear end of the sole, or tend to be pushed up by the support to push the rear end of the sole of the foot, so that the foot load is concentrated on the heel end. . What is more, the same user may feel that the support surface slope is too small in a certain position or section in the same pedal stroke, and the support surface inclination is too large in another position or section. In short, the pedal structure and action of the conventional elliptical exercise machine basically cannot satisfy the foot comfort of all users in the entire pedal stroke at the same time.

In view of the above problems, U.S. Patent No. 7,300,387 discloses a pedal structure suitable for an elliptical exercise machine. The main feature is that each pedal pivotally pivots its bottom center through a pivot corresponding to the left and right axial directions for guiding the pedal. On the support rod for the cyclic movement, in other words, even if the support rod is not moved (that is, the pedal stops at a certain position on the closed track), the length direction of the pedal can still be deflected relative to the support rod and the ground, whereby the user When the leg is moved, any position of the pedal on the closed trajectory can be deflected to a suitable angle in response to the user's current foot force. Another conventional method of similar technical idea is to connect the front and rear ends of the bottom of the pedal with the elastic body on the support rod so that the pedal support surface can be tilted forward or backward relative to the support rod at any time. However, the above two schemes may cause the foot support to be unstable due to the deflection/tilt resistance of the pedal, or the deflection/tilt resistance is too high, so that the foot must exert extra force, which becomes a burden on the user's foot. .

In addition to the aforementioned elliptical exercise machine, another type of indoor exercise equipment capable of providing similarly similar leg movements, such as those disclosed in U.S. Patent No. 7,568,999 and U.S. Patent No. 7,594,877, are also incorporated herein by reference. The two feet step on the station, but each pedal performs a reciprocating motion including up and down and front-rear displacement along a reciprocating trajectory of a straight line or an arc, thereby guiding the user's feet to perform forced leg raising and pressing motion. Most of the pedal support surfaces of such sports equipment maintain the same angle (e.g., horizontal) throughout the reciprocating stroke. The design also requires the user's sole to be guided by the pedal at a corresponding angle to form a predetermined aforementioned leg motion. The aforementioned comfort problems due to the difference between the ideal foot angle and the actual pedal angle are also present in such sports equipment.

In view of the above problems, the main object of the present invention is to provide a sports equipment capable of providing a user with two feet on the left and right pedals and guiding the lead portion to perform a repetitive motion in a cyclic or reciprocating manner, and allowing the user to The left and right feet of the left foot and the right foot can simultaneously obtain the support for the balanced balance of the pedals at various points in the movement stroke, and the feet are relatively comfortable.

Another object of the present invention is to provide a pedal assembly for the aforementioned sports equipment that can stably and securely support the sole of the user at each position in the reverse motion to make the foot more comfortable.

In order to achieve the above main object, the sports equipment provided by the present invention comprises a frame body and two left and right pedals. The frame body is disposed on the ground, and the left and right pedals are supported on the frame body, and can be along the frame body. A predetermined or free motion trajectory includes a repetitive motion of front and rear and up and down displacement, and the left and right pedals are mutually restrained and moved in the forward and backward directions in the up and down direction, and at the same time, each pedal is in any position on the motion trajectory. There is a corresponding fixed angle, which is not deflected at this position; the main feature is that the support surface of each pedal generally has a shape that extends straight in the width direction but gradually bulges from the opposite ends to the central portion in the longitudinal direction. The central portion is for supporting an intermediate portion between the tip end and the heel end of the user's sole. Further, the pedal is structured such that the support surface maintains the aforementioned shape as a whole when subjected to the user's weight.

In order to achieve the above other object, the pedal assembly provided by the present invention is used for assembling a portion of the foot device for guiding the user's foot to perform a repetitive motion, and the pedal assembly is provided for the user to step on the support surface substantially in the width direction. a shape extending straight but extending gradually from the opposite ends to the central portion in the longitudinal direction, the central portion for supporting an intermediate portion between the tip end of the foot of the user and the heel end, and further, the structure of the pedal assembly The support surface can maintain the aforementioned shape as a whole while being subjected to the user's weight.

According to the above technical means of the present invention, during the movement of the leg, the middle portion of the user's sole can always be supported by the central region of the pedal supporting surface, and at the same time, the entire area of the sole or the sole of the foot will depend on the angle of the foot and the pedal. The relationship between the angles and the center of gravity, slightly forward or backward abuts on the support surface, so the feet can simultaneously obtain the balanced and stable support of the pedals at various points in the movement stroke.

Referring to Figures 1 and 2, the sports equipment provided by a preferred embodiment of the present invention basically belongs to the elliptical exercise machine described above, and its major structure and actuation principle are all known techniques. The following is only a brief description: the structure mainly includes a body (10) disposed on the ground, a crank mechanism (20) disposed at the front end of the frame body (10), and two left and right swing arms (30) connected to the crank mechanism (20) and the frame body (10) The left and right support rods (40) between the rear end rails (12), the left and right two links (50) coupled to the two swing arms (30) and the two support rods (40), and respectively The left and right pedals (60) are fixed to the rear ends of the two connecting rods (50); more specifically, the front ends of the respective supporting rods (40) are guided by the cranks (22) for circular motion, and then The end can be guided by the guide rail (12) to reciprocate back and forth, and the front end of each link (50) can be guided by the bottom end of the swing arm (30) for swinging back and forth, a predetermined portion near the rear end and the corresponding support A predetermined portion of the rod (40) is pivotally connected; thereby, the pedal (60) fixed to the rear end of the connecting rod (50) can perform a cycle including front and rear and up and down displacement along a substantially elliptical closed path (T) (Note: the closed trajectory (T) in the figure is a schematic trajectory of the front end portion of the pedal (60)), and the left and right cranks (22) based on the crank mechanism (20) are maintained at 180 degrees, and the foregoing The two pedals (60) are mutually restrained to move in the forward and backward and up and down directions and maintain a substantially relative position on the aforementioned closed trajectory (T); at the same time, the angle of the pedal (60) relative to the ground is in the aforementioned cyclic motion. The corresponding cyclic changes.

When in use, the user steps on the left and right pedals (60) and can hold the grips (32) on the top left and right swing arms (30) as needed. The pedal (60) (and the grip) moves along its predetermined trajectory such that the foot is guided by the pedal (60) to circulate along the aforementioned closed trajectory (T) and cyclically changes the angle of the foot with the pedal angle. During the process, the position of the user's body and center of gravity in the front and rear axial and left and right axial directions will be substantially maintained between the left pedal (60) and the right pedal (60), so that the left and right pedals (60) will continue to be used. The weight of the person.

As shown in Fig. 3, each of the pedals (60) has a front end (62) and a rear end (64) opposite to each other, and an inner side (66) and an outer side (68) opposite to the left and right, the foregoing front and rear two The connecting line of the end (62) (64) defines a longitudinal direction (L), and the connecting line of the inner and outer sides (66) (68) defines a width direction (W) perpendicular to the longitudinal direction (L). Like most conventional elliptical exercise machines, the length direction (L) of each pedal (60) in this embodiment with respect to the ground will cyclically change with the same cycle as the aforementioned cyclic motion, and the width direction (W) is It is fixed and maintains the left and right axial directions corresponding to the frame body (10).

Please refer to Figures 4 to 6 again. Each pedal (60) is mainly composed of a main part (70), a bottom pad (80) and a surface layer (90). The main part (70) is shot by plastic. Formed, locked on a metal plate (52) inside the rear end of the connecting rod (50), having a flat plate portion (72) pressed against the top side of the aforementioned plate (52), and surrounding the flat plate portion (72) a low wall portion (74) on the left and right sides and the front side, the top surface of the flat plate portion (72) is substantially rectangular, and the long axis and the short axis thereof correspond to the longitudinal direction (L) and the width direction, respectively. (W). The bottom pad (80) is injection molded by rubber, has a main body portion (82) superposed on the top side of the flat plate portion (72), and a plurality of lower portions (84) of the main body portion (82) pass down through the flat plate portion ( 72) and the pallet (52) is provided with a perforated columnar portion (86), and the bottom end of each columnar portion (86) is embedded on the bottom side of the pallet (52) so that the bottom mat (80) can be positioned at the main On the piece (70). The outer edge contour of the main body portion (82) of the bottom pad (80) corresponds to the top surface shape of the flat plate portion (72) of the main member (70), and the bottom surface (84) substantially forms a plane to abut the flat portion (72) Top surface. On the other hand, the top surface (88) of the main body portion (82) as a whole extends straight in the aforementioned width direction (W) (in this embodiment, equal to horizontal extension) but in the aforementioned longitudinal direction (L) by relative two The shape that gradually bulges toward the central area. The foregoing skin layer (90) is also injection molded by rubber, completely covered and glued on the arched top surface (88) of the bottom pad (80), and the surface (92) correspondingly presents a straight extension in the width direction (W) but The shape in the longitudinal direction (L) is gradually arched from the opposite ends to the central region. The inner surface (96) of the surface layer (90) and the top surface (88) of the bottom pad (80) are respectively formed with a plurality of concave grooves and ridges (not labeled) which are fitted to each other to reduce the slippage of the surface layer (90). may.

Unlike the planar support surface of a sports equipment such as a conventional elliptical exercise machine, the pedal (60) of the present invention is an arched surface (92) of the aforementioned surface layer (90) for the user to step on and in the longitudinal direction. The central region on (L) supports the intermediate portion between the tip of the foot of the user's sole and the end of the heel. In terms of size, the length of the connecting line between the front and rear ends of the aforementioned surface (hereinafter referred to as the supporting surface) (92) is between 300 and 400 mm, and at the same time, the most arched portion of the supporting surface (92) to the aforementioned connecting line The height is between 13 and 34 mm. Wherein, the most arched portion of the support surface (92) is still lower than the low wall portion (74) of the aforementioned main member (70). In this embodiment, the support surface (92) integrally forms a convex curved surface with a constant curvature. When viewed from the side (as shown in FIG. 5), the support surface (92) exhibits an arc from the front end to the rear end as a whole. An arc between 18 and 38 degrees.

Further, in the above composition, the hardness of the surface layer (90) which is the same as the rubber material is lower than the hardness of the bottom pad (80), specifically, the material of the bottom pad (80) is styrene-butadiene rubber (SBR) and polybutylene. A synthetic rubber (BR) having a hardness of 60 to 70° or 65±5° ShoTe A; a surface layer (90) of isoprene rubber (IR) having a hardness of 50 to 60° or 55±5 ° Shore A, and the average thickness is significantly less than the average thickness of the body portion (82) of the bottom pad (80). With the pedal structure, the user has a better tactile feel when stepping on the station, and when the pedal (60) is subjected to the weight of the user, the aforementioned support surface (92) can maintain the aforementioned shape as a whole without causing specific Deformation.

In the present invention, the underpad may be set to a higher rubber hardness or made of a harder material (e.g., plastic) to provide a more solid arched top surface to support the flexible surface layer. Of course, the pedal in the present invention may not have the aforementioned surface layer. For example, the arched top surface of the bottom pad may be directly used as a supporting surface, or the plastic main body may be directly formed into an arch supporting surface.

By the shape of the support surface, when the user uses the above-mentioned sports equipment, at any position on the closed track (T), if the user's foot angle matches the pedal angle at the position, that is, the foot tip The connecting line with the heel end is substantially parallel to the longitudinal direction (L) of the pedal (60), and most of the area centered on the center of the sole or the sole of the foot is offset from most of the area of the supporting surface (92) centered on the central area. Connected, and the center of gravity falls substantially at the center of the support surface (92); if the angle of the foot is somewhat different from the angle of the pedal, the middle portion of the user's sole is still supported by the central portion of the arched support surface (92), Most of the area of the front or back of the sole will abut the support surface (92) slightly or slightly behind the center of gravity. As the cyclic motion progresses, the relationship between the pedal angle and the angle of the foot may continuously change, but the contact area of the user's sole and the supporting surface (92) may remain unchanged through the moderate arching shape of the aforementioned supporting surface (92). Or the change is very small, only the center of gravity of the foot is slightly displaced back and forth. In this way, the user's feet can simultaneously obtain the balanced and stable support of the pedal (60) at various points in the exercise stroke, and the foot load can be dispersed, and is not concentrated on the toe or the heel, which is more comfortable.

The pedal supporting surface (92) in this embodiment (ignoring the slip-proof or decorative protrusions and recesses scattered on the surface) integrally forms a convex curved surface which is gradually arched from the front and rear ends toward the central portion. The curvature must be within an appropriate range to allow the user's foot to maintain a large area against the support surface (92) during movement, while at the same time conforming to the angular relationship between the foot and the pedal, the center of gravity is naturally displaced back and forth. . If the aforementioned curvature is too small (ie, the arch is not obvious), the above functions will not be effective, and the result may be similar to the conventional planar support surface; if the aforementioned curvature is too large (ie, the arch is obvious), the foot load may be concentrated. In the middle of the sole of the foot. At normal pedal lengths, the aforementioned curvature is preferably between 18 and 38 degrees.

Referring to FIG. 5, from another point of view, the support surface (92) has a front front support region (93), a rear rear support region (94), and a front support region. (93) a central support region (95) between the rear end support region (94) for supporting a front end portion, a rear end portion of the sole of the user, and an intermediate portion between the front end portion and the rear end portion, wherein The connecting line of the front and rear ends of the central supporting area (95) is substantially parallel to the longitudinal direction (L), and the rear end of the front end supporting area (93) abuts the front end of the central supporting area (95), and the front end supporting area ( 93) The connecting lines of the front and rear ends are gradually inclined from the back to the front, the front end of the rear end supporting area (94) is adjacent to the rear end of the central supporting area (95), and the front end supporting area (94) is front and rear. The connecting line at the two ends is gradually lowered from the direction of the journey.

Of course, the pedal supporting surface in the present invention is not limited to a standard convex curved surface having a constant curvature. For example, the arch supporting surface may be a certain section (for example, the central supporting area) having a relatively small curvature and other intervals ( For example, the front end and the rear end support area have a relatively large curvature, or the support surface may be formed by a plurality of laterally extending strips or rectangular planes connected at different inclinations. In short, the whole is presented by the front. The shape of the latter two ends gradually bulging toward the central area.

In addition, the condition that the supporting surface is provided by the extremely hard structure is excluded. When the pedal in the present invention receives the weight of the user, the supporting surface is more or less deformed, but the above deformation does not specifically affect the overall shape of the supporting surface. . For example, suppose that the pedal has an arch-shaped supporting surface similar to a spring structure, and although it has a curved surface with a curvature within the aforementioned preferred range (18 to 38 degrees) before being stepped on, the flattening arc is less noticeable when stepped on. Such a curved surface (for example, 10 degrees or less) is difficult to exert the above-described effects of the present invention.

In the elliptical exercise machine provided by the embodiment, the user can adjust the long axial inclination of the closed trajectory (T) before use and during use, and the technical means are disclosed in Japanese Patent No. 7,654,936, mainly The rear end of the guide rail (12) is pivotally connected to the bottom of the frame body (10), and the front end of the guide rail (12) can be adjusted and positioned at different heights by electric or manual, by allowing the rear end of the support rod (40) to be inclined at different angles. The movement of the guide rail (12) is such that the closed trajectory (T) of the pedal (60) driven by the central portion of the support rod (40) also exhibits different inclinations to achieve the purpose of adjusting the difficulty of movement. Wherein, when the closed trajectory (T) changes, the angle of the pedal (60) relative to the ground may also slightly change, but based on the effectiveness of the pedal supporting surface (92) of the present invention, the user is under various motion trajectories. Get comfortable foot support.

A number of different types of elliptical motion machine configurations and techniques for adjusting the pedal trajectory are also disclosed in the prior U.S. Patent No. 7,654,936, which is equally applicable to the present invention. More broadly, the present invention is applicable to a variety of elliptical exercise machines or substantially similar sports equipment, including that the closed trajectory of the pedal is fixed, adjustable, or can be changed in response to the force (for example, as disclosed in Japanese Patent No. 6,689,019 technology). In addition, the present invention is also applicable to a sports apparatus in which a pedal is reciprocated in a straight line, an arc, or the like (for example, the type disclosed in Japanese Patent No. 7,568,999 and No. 7,594,877). Furthermore, the present invention does not exclude that the reverse motion of the pedal includes left and right displacement, and the width direction of the pedal does not completely correspond to the left and right axial directions. In summary, in the present invention, the exercise equipment performs leg movement through a left and right two pedals for a standing user, and the pedal may repeatedly move on various shaped or free closed or non-closed motion tracks, and left. The right second pedals are mutually restrained and move in opposite directions in the front, back, and up and down directions. At the same time, each pedal has a corresponding fixed angle at any position on the motion track.

For the elliptical exercise machine of the above embodiment, "the left and right pedals are mutually restrained and move in the reverse direction in the front and rear and the up and down direction", that is, for example, when the left pedal (60) is along the closed track (T) When moving backwards and backwards, the right pedal (60) is forced by the mechanism to move up and forward along the closed trajectory (T), and vice versa. Because the left and right pedals of such sports equipment are arranged in tandem during exercise, the center of gravity of the user is usually kept between the left and right pedals (unlike the use of a regular stepper). The center of gravity alternates between the two feet, so that the left and right pedals continue to share the weight of the user, and the left and right soles are properly supported by the arched support surface.

The pedal in the sports equipment provided by the present invention can also be designed to allow the user to select the structure of the shape of the support surface. For a simple example, imagine the arched bottom pad (80) of the pedal (60) in the previously disclosed embodiment (along with The surface layer (90) is assembled on the main part (70) in such a manner that it can be detachably mounted, so that the user can choose to mount the bottom pad (80) according to personal preference and step on the arched support surface. To move, or to remove the bottom pad (80), step on the planar support surface provided by the main part (70) or the arcuate support surface with less curvature to move. Of course, in order to achieve the above functions, the pedal assembly that can be detachably attached is not limited to the aforementioned form, and may be, for example, a shell plate having an arched surface.
