Description

stair exercise equipment

[0001] The present invention relates to exercise equipment, and more particularly, to a stair-type exercise equipment that utilizes a step unit that forms an endless track and rotates in a circular motion to provide both efficient aerobic exercise and the effect of strengthening lower body muscles.

[0002] In general, a treadmill is composed of a first roller driven by a motor, a second roller positioned opposite the first roller, an endless belt connected to the first and second rollers to form an endless track, and a driving motor that rotates the first roller.

[0003] In this type of treadmill, the belt moves in an endless orbit as the first roller rotates, and the user runs on the belt.

[0004] However, when exercising on a treadmill, the amount of exercise was not large, so the effect was only seen if you exercised for more than an hour.

[0005] Additionally, since the treadmill only allows for aerobic exercise, separate exercise equipment had to be used to perform anaerobic exercise.

[0006] Meanwhile, the most effective leg exercise is known to be climbing stairs. This type of stair climbing combines aerobic and anaerobic exercise, making it a time-efficient lower body workout.

[0007] Accordingly, recently, many devices that allow step-type exercise have been developed, but in the case of existing step-type exercise devices, the devices were very complex or it was difficult to determine the exercise state due to the structure.

[0008] The present invention has been devised to solve the problems of the above-described prior art, and its purpose is to provide a stair-type exercise machine having a combination of compact components but an overall durable structure.

[0009] In addition, the purpose of the present invention is to provide a stair-type exercise device that facilitates the understanding of the amount of exercise and exercise state, and also increases the interest in exercise.

[0010] The tasks of one embodiment of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0011] In order to achieve the above object, the present invention provides a stair-type exercise device including: a main body unit formed to have a predetermined upward inclination angle toward the front; a handle unit provided on the front upper side of the main body unit; a first rotation shaft rotatably installed at the front upper end of the main body unit and a second rotation shaft installed at the rear lower end of the main body unit; a power transmission unit including a pair of chain parts connected to both ends of the first and second rotation shafts and rotating in an endless track; a plurality of step units, one side of which is continuously installed along the movement direction of the power transmission unit and rotates together when the power transmission unit rotates; and a resistance supply unit connected to the first rotation shaft and supplying a predetermined resistance to the power transmission unit.

[0012] Here, the step unit may include a foot plate having a support surface formed to support the user's feet and having both ends rotatably connected to the pair of chain parts, and a pair of rotary rod parts having one end rotatably connected to the lower rear portion of the foot plate and the other end rotatably connected to the pair of chain parts.

[0013] In addition, the handle unit may include an upper support frame installed parallel to the longitudinal direction of the main frame on the upper side of the main frame, two or more upper and lower frames provided at predetermined intervals upward along the longitudinal direction of the upper support frame, and a handle frame that is fixed and connects the upper ends of the upper and lower frames but has the same inclination angle as the main frame.

[0014] According to a stair exercise device according to one embodiment of one embodiment of the present invention configured as described above, the stair exercise device can be used stably by forming a compact configuration while achieving an overall durable arrangement and connection state between components, thereby reducing the failure rate and achieving high product reliability.

[0015] In addition, by applying a control module to the handle unit, it is possible to easily determine the amount of exercise and the state of exercise during stair climbing, and by providing the person exercising with various screens through the control module depending on the situation, it is possible to increase the interest in exercising.

[0038] The above main frame (111) may be formed in the form of a board having a predetermined thickness and area.

[0039] And, it is preferable that each of the above frames (112, 114, 116) be made of a metal material having a predetermined rigidity.

[0040] Next, the handle unit (120) includes a pair of upper support frames (121) installed parallel to each other along the longitudinal direction of the main frame (111) on top of each main frame (111), two or more upper and lower frames (122) provided at predetermined intervals upward along the longitudinal direction of each upper support frame (121), a handle frame (123) that connects and is fixed to the upper ends of the upper and lower frames (122) but has the same inclination angle as the main frame (111), and a transverse frame (124) that connects the front ends of the handle frames (123) on both sides.

[0041] As shown, an operation module (128) is provided in the upper central portion of the cross frame (124).

[0042] The power transmission unit (130) includes a first rotation shaft (131) rotatably installed at a front end of a main frame (111) forming the main body unit (110), a second rotation shaft (132) rotatably installed at a rear end of the main frame (111) forming the main body unit (110), a pair of first gear parts (133) axially coupled to both ends of the first rotation shaft (131), a pair of second gear parts (134) axially coupled to both ends of the second rotation shaft (132), and a pair of chain parts (135) installed in a form that connects the first gear part (133) and the second gear part (134) and rotates in an endless track manner.

[0043] In addition, the step unit (140) is installed continuously at predetermined distances along the movement path of the chain portion (135) forming the power transmission unit (130), and is configured to rotate together when the chain portion (135) rotates, but not interfere with adjacent step units (140).

[0044] To this end, the step unit (140) includes a footrest (141) in which both sides of the lower front portion are rotatably connected to the pair of chain portions (135) based on the chain portion (135) located at the top in a state in which a support surface for supporting the user's feet is formed and a chain portion (135) that rotates in an endless track manner is installed, and a pair of rotational rod portions (142) in which one end is rotatably connected to the lower rear portion of the footrest (141) and the lower end is rotatably connected to the pair of chain portions (135) respectively.

[0045] Here, as illustrated, in the chain section (135), auxiliary support shafts (143) are installed at predetermined intervals in a manner that crosses a pair of chain sections (135), and it is preferable that the other end of the rotational rod section (142) of each footrest section (141) is installed rotatably on each auxiliary support shaft (143).

[0046] In addition, the chain section (135) is provided with a separate installation member (148) for rotatably installing the front end of the footrest section (141) and the auxiliary support shaft (143) forming the step unit (140), and the footrest section (141) and the auxiliary support shaft (143) are rotatably installed on the installation member (148) by applying various known methods.

[0047]

[0048] The above resistance supply unit serves to supply a predetermined resistance to the power transmission unit (130).

[0049] The above resistance supply unit is composed of a resistance generation unit (150) and a resistance transmission unit (160), wherein the resistance generation unit (150) is installed to protrude outwardly from the front of the right main frame (111) and includes an installation frame (151) having an axial through hole (152), a shaft portion (153) that is rotatably installed while penetrating the axial through hole (152), a motor portion (154) that is connected to one side of the shaft portion (153), and a brake portion (159) and a first pulley portion (155) that are rotatably connected to the other side of the shaft portion (153).

[0050] The above installation frame (151) is configured to be joined to the front side of the main frame (111) by a joining method according to a known technology, and the shaft portion (153) is installed to be rotatable in a direction perpendicular to the longitudinal direction of the main frame (111).

[0051] When the above shaft part (153) is installed in the shaft through hole (152) of the above installation frame (151), a bearing member, etc. may be additionally applied.

[0052] In addition, the resistance generating unit (150) includes a third rotational axis (158) that is installed rotatably across the pair of main frames (111) in the area between the first rotational axis (131) and the second rotational axis (132), a second pulley part (156) that is fixed to the other side of the third rotational axis (158) outside the main frame (111), and a rotational belt part (157) that connects the first pulley part (155) and the second pulley part (156).

[0053] In addition, the resistance transmission unit (160) includes a first transmission gear (161) that is axially coupled to one side of the first rotation shaft (131), a second transmission gear (162) that is axially coupled to one side of the third rotation shaft, and a transmission belt portion (163) that connects the first transmission gear (161) and the second transmission gear (162).

[0054] According to one embodiment of the present invention, a stair-type exercise device (1) configured as described above, when a user climbs up while holding the handle frame (123) and stepping on the footrest (141) of the step unit (140), the chain portion (135) rotates in an endless track manner due to the user's own weight and the force applied by the user's feet.

[0055] At this time, the first transmission gear (161) rotates, and the rotational power of the first transmission gear (161) is transmitted to the second transmission gear (162) through the transmission belt part (163), and the second transmission gear (162) rotates the third rotation shaft (158) while rotating the second pulley part (156).

[0056] And, as the second pulley part (156) rotates, the first pulley part (155) rotates through the rotary belt part (157), and a predetermined resistance force is generated through the motor part (154), thereby generating a motion effect.

[0057] The above motor unit (154) can be configured in various known forms, such as electric, hydraulic, or wind pressure, and since this is obvious to those skilled in the art, a detailed description of this part is omitted.

[0058] According to a stair exercise device according to one embodiment of one embodiment of the present invention configured as described above, the stair exercise device can be used stably by forming a compact configuration while achieving an overall durable arrangement and connection state between components, thereby reducing the failure rate and achieving high product reliability.

[0059] In addition, by applying a sensor capable of detecting speed to the first rotation axis, etc., and applying a display-type operation module to the handle unit, it is possible to easily determine the amount of exercise and the state of exercise during stair climbing, and by providing various screens to the person exercising through the operation module according to the situation, it is possible to increase the interest in exercising.

[0060]

[0061] Fig. 7 is a perspective view showing the oil supply unit installed, Fig. 8 is an exploded perspective view of the oil supply unit, and Fig. 9 is a combined perspective view of the oil supply unit.

[0062] As shown, according to the present embodiment, an oil supply unit (190) for supplying oil to the chain section (135) is provided.

[0063] The above oil supply unit (190) includes an oil rotation shaft (191) that is rotatably installed on a main frame (111), a tubular impregnation part (192) that is coupled to cover and enclose a portion of the other end of the oil rotation shaft (191), and a brush module (196) that covers and encloses the outside of the impregnation part (192).

[0064] The above impregnation part (192) may be made of a natural or sponge material so as to be in an oil-impregnated state, and may be formed in a form in which a superabsorbent resin is included inside and outside to absorb oil and discharge the absorbed oil when a predetermined pressure is applied.

[0065] In addition, at least two impregnation pieces (192a) having a predetermined length are provided at one end of the impregnation section (192), and it is preferable that the impregnation pieces (192a) are made of cloth.

[0066] Meanwhile, the brush module (196) includes a covering member (193) that is fixed by covering the outside of the impregnation member (192) in a fitting manner while the impregnation member (192a) is exposed to the outside, and a brush member (194) that is provided on the outer surface of the covering member (193).

[0067] Here, the covering member (193) and the brush member (194) are made of a synthetic resin material that has a predetermined rigidity and is capable of bending, and the covering member (193) is provided with a plurality of through holes (195) that penetrate the inside and outside at positions that do not overlap with the positions where the brush member (194) is installed.

[0068] In addition, the oil supply unit (190) includes a box portion (198) in the shape of a square box with an open top and an internal receiving portion formed therein, and sponge portions (199) provided on both sides of the internal receiving portion of the box portion (198).

[0069] Such an oil supply unit (190) is installed so that the brush portion (194) comes into contact with the chain portion (135) and, when the chain portion (135) rotates, the brush portion (194) also rotates about the oil rotation axis (191), and the impregnation piece (192a) intermittently comes into contact with the oil contained inside the box portion (198) due to its own weight. When the chain portion (135) rotates, the oil moves to the impregnation portion (192) through the impregnation piece (192a) and is stored while rotating about the oil rotation axis (191), and is then discharged to the outside through the passage hole (195).

[0070] In addition, the discharged oil is supplied to the chain section (135), and the brush section (194) can supply oil and clean the chain section (135).

[0071] In addition, the oil applied to the brush portion (194) through the sponge portions (199) on both sides of the box portion (198) can be smoothly absorbed into the sponge portion (199) and then re-supplied to the inside of the box portion (198).

[0072] Meanwhile, although not shown in detail, the brush parts (194) are arranged in a plurality of rows at predetermined angles along the circumferential direction of the covering tube (193), and the brush parts (194) arranged in the same row based on the longitudinal direction of the covering tube (193) may be arranged so that each row has different stiffness.

[0073] That is, when the chain part (135) rotates, the brush parts (194) that come into contact with each other have different rigidities for each row based on the longitudinal direction of the capping part (193). Therefore, when the brush parts (194) with strong rigidity come into contact with the chain part (135), the oil rotation shaft (191) is smoothly rotated when the chain part (135) rotates, and oil is supplied to the chain part (135). Alternatively, when the brush parts (194) with weak rigidity that is easy to bend come into contact with the chain part (135), the brush parts (194) are bent when the chain part (135) rotates, and the contact with the chain part (135) is maintained for a long time. This can be used to clean the chain part (135) by removing foreign substances.

[0074]

[0075] Those skilled in the art will appreciate that the above-described embodiments of the present invention can be implemented in other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, the above-described embodiments should be understood as illustrative in all respects and not restrictive. The scope of the present invention is indicated by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included within the scope of the present invention.
