Description

  The present invention relates to a (real-run type) exercise assisting device capable of performing an operation as close as possible to an actual operation.

Conventionally, an exercise assisting device is known (see Patent Document 1).
The exercise assisting device includes a platform that a user steps on, a main body that supports the platform from below, and a holder that is disposed above the main body. An exercise assisting device for holding a user's trunk having a center of gravity in front of a position where the user steps on the trapezoid, wherein the user holding the trunk moves the center of gravity forward while stepping on the step on the trapezoid. At this time, the trapezoid is moved up and down with respect to the main body and the holding body is moved back and forth with respect to the main body, thereby restricting the user from leaning forward.
Further, in Patent Document 1, the trapezoidal body and the holding body are pivotally connected and pivotably supported on the main body so that the vertical swinging of the trapezoidal body can be changed to the longitudinal swinging of the holding body. There is also disclosed a link body that is converted to restrict the user from leaning forward.

<Trapezoid 2>
As shown in FIGS. 1, 2, and 8 to 10, the trapezoid 2 is used by a user U, and includes a table shaft 12 that pivotally supports the trapezoid 2 on a main body 3 so as to be vertically swingable. Have.
The trapezoidal body 2 may have any configuration as long as the user U can step on the trapezoidal body 2. For example, the trapezoidal body 2 includes a base frame 20 long before and after, and a tread surface member 21 provided on the base frame 20. It does not matter.

Among the sizes of the trapezoidal body 2, the front-rear length of the tread surface member 21 in the trapezoidal body 2 is not particularly limited. In this state, the thickness may be 600 mm or more and 2100 mm or less, preferably 700 mm or more and 1900 mm or less, more preferably 800 mm or more and 1700 mm or less (1121.6 mm or the like).
Further, among the sizes of the trapezoidal body 2, the vertical position (height position) of the rear end of the tread surface member 21 from the upper surface of the main body 3 in the trapezoidal body 2 is not particularly limited. In the attached state (the state in which the tread surface 2a is inclined forward), the distance may be 100 mm or more and 300 mm or less, preferably 110 mm or more and 260 mm or less, more preferably 120 mm or more and 220 mm or less (164.6 mm or the like).

<Tab spindle 12>
As shown in FIGS. 1, 2, 8, and 9, the base shaft 12 pivotally supports the base body 2 so as to be vertically swingable with respect to the main body 3. It is attached across the front end and the front end of the main body 3.
The trapezoid 12 may have any configuration as long as it supports the trapezoid 2 so that it can swing up and down with respect to the main body 3. For example, a configuration using a hinge 12 ′ may be used.

The hinge 12 ′ serving as the base shaft 12 includes a pair of blades 12 a ′, a pair of bearings 12 b ′ provided on the pair of blades 12 a ′, and a shaft inserted through the pair of bearings 12 b ′. 12c '.
In such a hinge 12 ′, one blade 12 a ′ is attached to the lower surface of the front end of the trapezoidal body 2 (the lower surface of the front connecting member 23 a described later), and the other blade 12 a ′ is connected to the front end of the main body 3. It is attached to the upper surface (shaft support 31).

The hinge 12 ′ is attached to the trapezoidal body 2 and the main body 3 in a state where the pair of blades 12 a ′ are folded so that the bearing 12 b ′ is located inside, and the hinge 12 ′ is attached to the hinge 12 ′. Or, a bonding member such as a double-sided tape or an adhesive).
The number of such hinges 12 ′ is not particularly limited. For example, with respect to one exercise assist device 1, the axial direction (the direction of the trapezoid 12) of the shaft portion 12 c ′ is In the case where a plurality of hinges 12 ′ (for example, three) having a predetermined left-right length (predetermined width) are provided in a direction substantially parallel to the left-right direction of the body 2 or the main body 3), or one exercise assist device 1 In contrast, the left-right length (width) is such that the axial direction of the shaft portion 12c '(the direction of the trapezoidal shaft 12) is substantially parallel to the left-right direction of the exercise assisting device 1 (the trapezoidal body 2 or the main body 3). Alternatively, one hinge 12 ′ having a length (width) substantially the same as or slightly shorter than the left and right length (width) of the exercise assisting device 1 (the trapezoid 2 or the main body 3) may be provided.

In addition to the hinge 12 ′, the platform 12 may be attached to the front end of the base 2 in a penetrating manner and may be supported by a bearing provided on the upper surface of the front end of the main body 3.
The trapezoid 12 causes the trapezoidal body 2 to make a circular motion around the trapezoid 12. However, even if it says a circular motion, the rocking angle of the trapezoidal body 2 is very limited, and at the same time, for example, the front-back length of a base frame 20 to be described later approaches the front-back length of the main body 3. By setting the length as long as possible, the movement of the trapezoid 2 can be approximated to a linear movement along the vertical direction, and it can be said that this movement distance is the amount of depression of the trapezoid 2.

<Table frame 20>
As shown in FIGS. 1, 2, and 8, the base frame 20 includes left and right base frames 22 that extend in the front-rear direction, a connecting member 23 that connects the left and right base frames 22, and a left and right base frame 22. And a face plate member 24 attached to the tread surface member 21.
The left and right pedestal frames 22 in the pedestal frame 20 are L-shaped in cross section, have a shorter front-rear length than the main body 3, and are attached to the lower surface (back surface) of a tread surface member 21, which will be described later, by screws or the like. , An adhesive such as a double-sided tape or an adhesive).

As described above, since the left and right base frames 22 have an L-shaped cross section (the long sides of the two plate members are substantially orthogonal to each other), the left and right base frames 22 stand a predetermined distance downward from the lower surface of the tread surface member 21. (One of the two plate members is attached substantially along the lower surface of the tread member 21, and the other of the two plate members is attached in a state of standing upright from the lower surface of the tread member 21. Is).
In the present invention, "standing downward" means not only standing vertically and downward, but also standing vertically and in addition to standing vertically ( Further, even if there is a slight vertical standing portion, it is sufficient that the vertical standing portion (further the horizontal direction) is smaller than the vertical standing portion.

There are a plurality of (for example, three) connecting members 23 in the base frame 20, and a front connecting member 23 a connecting the front end positions closest to the base shaft 12 in the left and right base frames 22 in order from the front, A middle connecting member 23b connecting the intermediate positions in the front-rear direction of the frame 22 and a rear connecting member 23c connecting the rear end portions of the left and right base frames 22 may be used.
The front connecting member 23a is formed of one member having a substantially L-shaped cross section, has a shorter left and right length (narrower width) than the tread surface member 21 described later, and is provided at the front end of the lower surface of the tread surface member 21. , Screws or the like (or a sticking member such as a double-sided tape or an adhesive).
Further, the front connecting member 23a also has an L-shaped cross section, and thus is mounted so as to stand up from the lower surface of the tread surface member 21 by a predetermined distance.

The middle connecting member 23b is composed of two members having a substantially L-shaped cross section similar to the front connecting member 23a and a member having a substantially U-shaped cross section (a groove having a square cross section). The two members have a shorter left and right length (narrower width) than the member 21, and these two members are attached at an intermediate position in the front-rear direction on the lower surface of the tread surface member 21 with an attachment member such as a screw (or a sticking member such as a double-sided tape or an adhesive member). Agent).
The upper end of the table spring member 18 and the like of the table adjustment unit 13 described below abuts on the middle connecting member 23b, and the upper end of the slide cushion member 14a described below abuts depending on the sliding position of the slide member 14. However, for example, a member having a substantially L-shaped cross section and a member having a substantially U-shaped cross section (a groove having a square cross section) are partially cut out, or the cutout causes The tip of the base spring member 18 may be configured to enter the inside of these members, or the open side of the member having a substantially U-shaped cross section in the middle connecting member 23b may be the tread surface member 21 side. The upper end of the slide cushion member 14a of the slide member 14 may be attached to the lower surface of the tread surface member 21 so that the upper end of the slide cushion member 14a of the slide member 14 contacts the lower surface (back surface) of the member having a substantially U-shaped cross section. .
Also, of the middle connecting member 23b, the member having the L-shaped cross section is also mounted so as to stand up from the lower surface of the tread surface member 21 by a predetermined distance, and the member having the substantially U-shaped cross section is also provided by the thickness thereof. Thus, it can be said that the tread surface member 21 is attached so as to stand up from the lower surface of the tread surface member 21 by a predetermined distance.

The rear connecting member 23c is also composed of a member having a substantially L-shaped cross section and a member having a substantially U-shaped cross section (a groove having a square cross section), and has a shorter left and right length than the tread surface member 21 described later. (Narrower width), and these two members are attached to the rear end portion of the lower surface of the tread surface member 21 (slightly forward from the rear end) by an attachment member such as a screw (or a sticking member such as a double-sided tape or an adhesive member). Agent).
Unlike the middle connecting member 23b, the rear connecting member 23c is attached to the lower surface of the tread surface member 21 so that the open side of the member having a substantially U-shaped cross section is the rear side, and the substantially U-shaped cross section is provided. The mold member stands downward (slightly rearward downward) from the lower surface of the tread surface member 21.
Also, among the rear connecting members 23c, the member having the L-shaped cross section is also mounted so as to stand up from the lower surface of the tread surface member 21 by a predetermined distance, and the member having the substantially U-shaped cross section is used. It can be said that the member is mounted so as to be erected (for example, twice or more higher) than the erected height of the member.

Since the lower end of the member having a substantially U-shaped cross section is engaged with a body stopper 38 of the main body 3 described later, the lower end of the member having a substantially U-shaped cross section can be said to be the platform stopper 25.
The upper surface of the lower end portion of the platform stopper 25 contacts the lower surface of the main body stopper 38 of the main body 3 when the platform 2 swings upward by a predetermined angle, and the movable range of the platform 2 (the platform 2 The top position).

That is, it can be said that the uppermost position of the trapezoidal body 2 can be adjusted by changing the standing height (vertical length) of the platform stopper 25.
The left and right lengths of the connecting members 23a to 23c described above, that is, the distance between the left and right base frames 22 may be equal to or slightly larger than the shoulder width of the user U.

The face plate member 24 in the base frame 20 is a single plate member attached to the left and right outer surfaces of the left and right base frames 22 and the rear surface of the tread surface member 21 described later. Cover the side and rear surfaces of the As a result, the base frame 22, the connecting members 23a to 23c of the base frame 20, the base stopper 25, the substantially rectangular frame 26 described later, the base adjustment part 13, and the like cannot be seen from the left, right, outside and rear.
The face plate member 24 is attached to the left and right base frames 22 by an attachment member such as a screw, and the tread surface member 21 has a substantially L-shaped cross section (or a substantially U-shaped cross section) in the left-right direction. The mounting member is attached to the rear surface (lower surface) of the tread surface member 21 with a screw or the like via a connecting member having a predetermined length.

Also, it can be said that the bent portion at the lower end of the rear face plate 36a is sunk below the lower surface of the above-described rear connecting member 35d (abuts on the lower surface of the rear connecting member 35d).

The notch in the center in the left-right direction of the upper side of the rear plate 36a has a substantially rectangular shape with a predetermined depth and a predetermined width (a predetermined left and right length) in a rear view. The lower left and right corners are further cut downward in a substantially U-shape (see FIG. 10).
By such a notch, an adjustment lever 17 of the platform adjustment unit 13 described later can be locked at both ends of the notch.

The guide member 36b of the rear surface member 36 has a plate member that has a crank shape in cross section (a type in which two substantially L-shaped cross sections are combined) and is long on the left and right, and a substantially rectangular plate material that has a predetermined thickness and is long on the left and right. These two plate members are mounted on the upper end of the rear plate 36a by a mounting member such as a screw in a state where an uncut portion (left and right outer portions of the upper end) is sandwiched from the front and rear at the upper end of the rear plate 36a. Attached to.
As a result, a gap having a predetermined vertical width is formed in which the adjustment lever 17 of the base adjustment unit 13 described later can swing right and left and can be locked at both ends of the notch (see FIG. 10).

As described above, since the guide member 36b can be retrofitted to the rear plate 36a, the base adjustment unit 13 is attached to the middle connection member 35c or the rear connection member 35d of the main body frame 30, and the adjustment lever 17 is provided. Is inserted into the notch of the rear plate 36a, and then the guide member 36b is attached to the rear plate 36a, so that the adjustment lever 17 of the base adjustment unit 13 is passed through a gap of a predetermined vertical width formed in the rear member 36. I can do it.
The attachment pieces 37 of the main body frame 30 project downward from a middle part in the front-rear direction (slightly rearward from the center) in the left and right outer surfaces of the left and right main body frames 34 in a substantially rectangular shape that is long in the front-rear direction.

<Slide member 14>
As shown in FIGS. 8 and 10 to 14, the slide member 14 of the platform adjustment unit 13 is disposed below the platform 2 and is in contact with the lower surface of the platform 2 (in particular, the platform described above). The lower surface (rear surface) of the middle connecting member 23b and the lower surface (rear surface) of the tread surface member 21 in the base frame 20 of the shape body 2 and the contact position between the lower surface (rear surface) and the slide cushion member 14a described later) can be changed.
The shape of the slide member 14 is also not particularly limited. For example, the slide member 14 is a substantially rectangular plate material in plan view, and the left and right ends thereof are respectively at right angles from the left and right ends by a predetermined distance in a substantially right angle in front view. The bent section may be substantially U-shaped.

The slide member 14 having a substantially rectangular shape in a plan view has a front-end center portion in the left-right direction cut out in a substantially U-shape. Due to this cut-out, even if the slide member 14 is at the foremost position, it will be described later. There is no contact with the lever shaft 16 (see FIG. 12).
At the middle part in the front-rear direction at the left and right ends of the slide member 14, slide cushion members 14a that abut against the lower surface of the tread surface member 21 (particularly, the middle connecting member 23b, etc.) are provided upright.

Depending on the slide position of the slide member 14, the upper end of the slide cushion member 14a is actually the lower surface of the middle connecting member 23b in the base frame 20 or the lower surface of the tread surface member 21, depending on the slide position of the slide member 14. Then, the contact position between the upper end of the slide cushion member 14a and the lower surface of the trapezoidal body 2 is changed (changed).
By changing the contact position, the vertical swing width of the trapezoid 2 is adjusted. More specifically, as described above, the width of the trapezoid 2 actually swinging (the trapezoid 2 Swings to adjust the range reached from the uppermost position to the lowermost position, and the force required to swing the trapezoidal body 2 (the user U moves the trapezoidal body 2 (stepping The force (user U steps on the trapezoidal body 2 (the tread surface 2a)) required to adjust the stepping force of the surface 2a) or to swing the trapezoidal body 2 further downward from a predetermined swing position. It can be said that the adjustment of force, difficulty of stepping on, etc. is also adjusted.

The vertical position of the slide cushion member 14a means the front and rear positions of the table spring member 18 and the table cushion member 19, which will be described later, when the slide member 14 is at the frontmost position (the table frame in the above-described table body 2). It may be substantially the same as the lower surface (back surface) of the middle connecting member 23b in the frame 20 (the position where the upper end of the slide cushion member 14a abuts) (see FIGS. 11, 12, and 14). The standing front-back position may be a position where the upper end of the slide cushion member 14a abuts on the lower surface (back surface) of the tread surface member 21 in the base 2 when the slide member 14 is at the last position. .
The shape of the slide cushion member 14a is not particularly limited as long as its upper end is in contact with the lower surface of the trapezoidal body 2 (the lower surface of the middle connecting member 23b or the lower surface of the tread surface member 21). It may be substantially cylindrical or substantially cylindrical, and its material is not particularly limited as long as it has cushioning properties.For example, a urethane resin having a predetermined hardness or a rubber material may be used. good.

The height at which the slide cushion member 14a is erected is not particularly limited either. When the base 2 is at the uppermost position (when the upper surface of the base stopper 25 and the lower surface of the main body stopper 38 are in contact with each other). Also, when the slide member 14 is at the foremost position, the height at which the upper end of the slide cushion member 14a contacts the lower surface of the middle connecting member 23b in the base frame 20 of the base body 2 (in other words, The vertical height may be higher than the distance from the lower surface of the middle connecting member 23b to the upper surface of the slide member 14 when the trapezoidal body 2 is at the uppermost position.
Since the slide cushion member 14a has such an upright height, the first step feeling of the user U is softened (or the user U steps on the trapezoid 2 (the step surface 2a)). From the beginning, an upward biasing force acts on the trapezoidal body 2).

A pin guide hole 14b of a predetermined length that is oblique and slightly curved (curved) is provided in a substantially central portion in the left-right direction in the rear half portion of the slide member 14. Is slidably inserted along the length direction.

It can be said that, while being inserted so that the relative position can be changed, the telescopic guide shaft 6A3 is inserted into the elastic cushion member 6A6 so that the relative position can be freely changed with respect to the elastic cushion member 6A6.

When the holding member 4 is moved forward by applying a forward force to the holding member 4 (the front moving state of the holding member 4), the expansion / contraction guide shaft 6 </ b> A <b> 6 moves the expansion / contraction guide shaft 6 </ b> A <b> 3 inside the cylindrical member of the expansion / contraction guide 6 </ b> A <b> 2. Is moved forward (sliding), and the rear stopper 6A5 comes closer to the guide support plate 6A1 (that is, the later-described elastic portion 7 contracts), so that the elastic cushion member 6A6 moves forward together with the rear stopper 6A5. Finally, the front end of the elastic cushion member 6A6 comes into contact with the rear surface of the guide support plate 6A1.
At this time, the elastic cushion member 6A6 reduces (reduces) the impact that abuts (collides) with the guide support plate 6A1.
The stretchable cushion member 6A6 may be made of any material as long as it can reduce (reduce) the impact that has come into contact with (collide with) the guide support plate 6A1.
