Description

Inverted exercise equipment with improved function {UPSIDE DOWN EXERCISE EQUIPMENT WITH IMPROVED FUNCTION}

The present invention relates to an inverted exercise device, and more specifically, to an inverted exercise device that can maximize the efficiency of muscle relaxation and spine correction function in the process of reversing the user from an upright state to a hanging state upside down.

As modern society becomes industrialized and urbanized and transportation methods develop, not only is the time spent walking or moving gradually decreasing, but the amount of exercise is also gradually decreasing due to lack of time and space to exercise. This lack of exercise not only causes muscle aging and stiffness, makes people feel easily fatigued, but is also a major cause of adult diseases.

Since humans are animals that walk upright, abnormalities in the neck, waist, or back, that is, diseases related to spinal discs, can commonly occur. The spine is largely composed of cervical vertebrae (7 in the neck region), thoracic vertebrae (12 in the chest region), lumbar vertebrae (5 in the waist region), 1 sacrum, and 3 to 6 coccyxes. At this time, the disc exists between bones and absorbs shock. It is a cartilage that acts as a cushion to absorb blood and is a type of joint. It is composed of a gel-type nucleus pulposus composed of about 80% water and a fibrous annulus fibrosus that surrounds and protects the nucleus pulposus.

Because various central nerves pass through the spine, it is considered a very important organ. The intervertebral discs that make up the spine relieve the impact on the body, and are surrounded by strong ligamentous tissue that prevents them from being easily pushed out, allowing the spine to perform its function by distributing and absorbing weight.

Recently, as the time spent sitting on a chair increases, many cases of disc disease in the lumbar or cervical region are occurring, and the number of cases complaining of pain due to this is rapidly increasing.

Severe intervertebral disc herniation is treated through surgical methods, while ordinary pain is resolved through physical correction. The physical techniques include treatment techniques such as manual therapy, which corrects body parts by applying a certain amount of pressure.

Meanwhile, devices that allow people to hang upside down to maintain spinal health on their own are also becoming popular. The so-called 'upside-down' exercise device allows a person to hang by flipping up and down while supporting their feet on a footrest. With this inverted device, cartilage tissue damaged by weight pressure can be restored, it has the effect of straightening the back that is bent due to bad posture to increase height, and it can correct the body shape beautifully by retracting the belly that protrudes due to abdominal obesity. It is expected to have various effects, including treatment of cold hands and feet.

Korean Patent Publication No. 10-2012-0054775 discloses an inversion for waist correction, and Figure 1 is a perspective view of it.

Looking specifically, the bed 11 was installed in the center of the bracket fixing device 10, and an ankle fixing device 14 was provided at the bottom of the bed 11 to allow the user to hang upside down.

In the case of the above technology, in order to improve the conventional inversion, a pelvic fixation device (13) and an upper body fixation device (12) are installed separately at the waist, so that when the bed (11) is inverted, the entire force of the body weight is not applied to the ankle, but only a part of it is applied. Since a large portion of the body weight is held by the pelvic fixation device 13, it has the effect of distributing the force applied to the ankle.

In the case of the conventional inversion device, unlike multi-purpose exercise equipment, its use is limited because it cannot perform additional exercises other than simple hanging. As with the above technology, only minor improvements have been made, such as distributing weight or increasing convenience somewhat by electricizing rotation.

This is fundamentally because the conventional inversion device relies only on the action of gravity caused by the user's body weight, so it has limitations that make it difficult to apply additional exercise techniques or massage techniques.

Technology development is requested to improve the stretching and correction functions of these inverted devices, which have been distributed without significant changes, in a more active and efficient manner.

Accordingly, the present invention was created to solve the above problems, and its purpose is to provide an inverted exercise device with improved structure and function to maximize the effects of stretching and correction.

The present invention includes a support frame 200, a pivoting base 300 connected to the support frame so as to be able to rotate up and down, a hanger 400 connected to the pivoting base to support the user's feet, and a support for the user's upper body. and provides an inverted exercise device including a sliding bed (100) that is connected to the rotating base so that it can move up and down.

The sliding bed may perform a function of pulling the user's upper body by moving upward with respect to the rotating base in an inverted state in which the rotating base is rotated upward.

In addition, the pivoting base may include a body portion 310, an extension frame 301 extending below the guide portion and coupled to the hanger portion, and a guide portion 320 formed in the body portion.

In addition, the sliding bed preferably includes a support plate portion 110 disposed to face the body portion, and a guide spacer 120 that protrudes toward the rear of the support plate portion and moves along the guide portion.

On the other hand, the sliding bed has a first locking part 111 disposed above the support plate and hooked to the upper part of the body, and a second locking part 112 disposed below the support plate and hooked to the lower part of the body. It may be provided with a side plate portion 113 disposed to cover the side of the body portion.

The guide portion may have an inclination that protrudes rearward toward the top in the clearance space of the body portion.

The guide spacer allows the body part and the support plate part to form a first gap d1 in a standby state in which the sliding bed is disposed at the lower limit with respect to the rotating base, and in the inverted state, the sliding bed follows the guide part with respect to the rotating base to move up and down. While moving rearward during the sliding movement, the body portion and the support plate portion may form a second gap d2 smaller than the first gap.

In addition, the sliding bed may further include a functionalization unit 150 made of one or more of a vibrating device, a heating device, and an air expansion member.

By the configuration of the present invention described above, the effect of stretching and correction can be dramatically improved because it improves the conventional simple inversion device and has a sliding structure capable of upward and downward traction to relax the spine. there is.

In addition, since forward and backward movement can be done in parallel with upward and downward movement, there is an effect of changing the body during the inversion process and further diversifying the forces acting on the body.

In addition, by being able to configure functional parts such as vibration, heat, and expansion, the purpose of improving physical health can be flexibly adapted to the needs of various users.

Hereinafter, an inverted exercise device with improved functionality according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

In the following description, when a part is said to be 'connected' to another part, this includes not only the case where it is directly connected, but also the case where it is connected with another part or device in between. Additionally, when a part is said to 'include' a certain component, this does not mean that other components are excluded, but that it can further include other components, unless specifically stated to the contrary.

The present invention basically provides an inverted bed with improved functionality, including a support frame, a pivoting base connected to the support frame so as to be able to rotate up and down, and a sliding bed that is coupled to the pivoting base and adheres closely to the upper body, but is capable of sliding up and down. Exercise equipment is provided.

In the present invention, an inversion exercise device for a user to stand on his or her head by rotating in a roughly upright leaning state will be described. However, for commonly used configurations, known inversion devices that are commonly used can be applied.

In addition, the inverted exercise device with improved functions of the present invention can perform selected functions such as stretching, correction, exercise, and massage, and the user's purpose of use will not limit the concept of the present invention.

Figure 2 is a front view of an inverted exercise device with improved functionality according to the present invention.

In the description of the present invention, the rotating base 300 and the sliding bed 100 can be rotated up and down with respect to the support frame 200, and hereinafter, the state in which the user can sit in an approximately upright state is referred to as a standby state or a downward rotation state. , The state of hanging upside down with the top and bottom reversed is defined as an inversion state or an upward rotation state.

In addition, in the case of vertical direction, unless otherwise explained, the explanation will be unified based on the above-mentioned standby state.

The support frame 200 refers to a structure that supports the overall structure and is fixed to some extent on the floor. It supports the load of the rotating base 300, which can be rotated up and down, and can respond to changes in load and moments. If there is a structure, various known shapes may be selected.

In an embodiment of the present invention, the support frame 200 has a shape that widens front and rear as it goes toward the bottom, and the front support portion 210 and the rear support portion (220 in FIG. 3) branch from the rotation axis portion.

In the present invention, the support frame 200 and the rotating base 300 may be made of metal, preferably aluminum or stainless steel, so as to have basic rigidity. However, the material is optional.

The rotation base 300 is connected to the rotation axis of the support frame 200 so that it can be rotated up and down, and a hook 400 that can catch the instep is disposed on the lower side. The hook 400 may be coupled to an extension frame so as to be connected to the upper side supporting the back plate. This hook 400 may be made of a cushioning material such as rubber or sponge to secure an area in contact with the instep and support the load.

In addition, it would be desirable for the hook unit 400 to have a structure that adjusts the distance in the front and rear directions so that it can accommodate different foot sizes for each person. Known techniques may be applied in relation to the hanging portion 400.

The extension frame of the support frame 200 or the portion of the hook 400 may be configured with a front stopper 211 so that the lower limit angle rotated downward can be limited. This front stopper 211 sets a limit for downward rotation when a person is standing and supports the load.

Based on the illustrated state, the rotation base 300 is rotated upward at the rotation axis of the support frame 200 and is placed in an upside-down position. Here, upside-down inversion refers to a case where the hanger 400 is disposed relatively above the sliding bed 100. In the description of the present invention, upright does not necessarily mean a state perpendicular to the floor, and a state rotated to the lower limit of the maximum angle with respect to the support frame 200 may be considered an upright state.

In the present invention, the rotating base 300 does not directly contact the upper body, and the sliding bed 100 is interposed between the rotating base 300 and the body to provide close contact and friction with the upper body. The sliding bed 100 is arranged to be able to move up and down and/or back and forth with respect to the rotating base 300, and such movement will be described later.

Based on the illustrated state, the sliding bed 100 is coupled to the pivoting base 300 so that it can slide upward or longitudinally with respect to the pivoting base 300. In the process of rotating upward so that the hanger 400 moves upward, when the sliding bed 100 slides relatively upward, the upper body moves upward (lower side in an inverted state) based on the fixed position of the hanger 400. A further pulling function can be performed, and thus the stretching effect in the vertical direction can be maximized.

Regarding the rotational drive in the vertical direction, in one embodiment, it may be performed by the user's force, and in this case, a predetermined grip portion may be formed on the support frame 200.

In another embodiment, a predetermined controller and a motor may be provided to automatically rotate the rotating base 300 with respect to the support frame 200 using control power at the rotation axis. For this purpose, the rotation drive unit 230 may rotate the rotation axis. It may be configured in the area.

Figure 3 is a side view of an inverted exercise device with improved functionality of the present invention.

According to one embodiment of the present invention, the support frame 200 has a front support part 210 and a rear support part 220 respectively supporting the front and rear structures, and this structure allows the load during the rotation of the pivot base 300 to be applied. It can be dispersed. However, the structure of the support frame 200 is not limited to the form shown.

The depicted state represents a waiting state in which the user enters and settles or is stored, and the limit of downward rotation at the front stopper 211 can be determined as described above. Additionally, an upward stopper (not shown) that can set a limit of upward rotation may be provided on the upper side of the support frame 200 or the rear support portion 220 side.

A rotation drive unit 230 is formed at the rotation axis portion, so that the rotation angle and/or rotation speed can be controlled by inputting a predetermined control power. However, the present invention does not exclude manual rotation.

The rotating base 300 includes an extension frame 301 on the lower side so that the hanging portion 400 can be placed at an appropriate position, and may preferably be in the form of a single round bar or square bar.

Additionally, a member capable of supporting the sliding bed 100 from the rear is disposed on the upper side of the extension frame 301. Let us look in detail at the structure for supporting the movement of the sliding bed 100.

Figure 4 is an exploded view for explaining an embodiment of the rotating base and sliding bed in the inverted exercise device with improved functions of the present invention.

The rotation base 300 is connected to the rotation axis and rotates, and may be largely composed of a body portion 310 for supporting the upper structure and an extension frame 301 for connecting the lower hanging portion 400.

The body portion 310 may have an overall square plate shape, but the shape is optional. Since this body portion 310 mainly serves the function of supporting the load during rotation while guiding the up-down and/or forward-backward movement of the sliding bed 100, it may also be considered in some cases to be in the form of a rail.

The body portion 310 constitutes a guide portion 320 to guide the up-down and forward-backward movement of the sliding bed 100. The structure and function of the guide unit 320 will be described later.

The sliding bed 100 may be shaped to surround at least a portion of the edge of the body 310, and since it supports the back of the upper body, the front surface is preferably flat.

In the illustrated example, the front side of the rotating base 300 and the rear side of the sliding bed 100 are shown together.

The sliding bed 100 may include a support plate portion 110 that forms a support surface, and side plate portions 113 on both sides that can surround the side edges of the body portion 310 of the pivoting base 300. The side plate portion 113 is in close contact with or adjacent to a corner portion of the body portion 310 and can perform a guiding function when moving in the vertical direction and at the same time protect the internal components. Note that the side plate portion 113 may have the advantage of preventing contaminants from entering the interior and improving aesthetics.

Additionally, locking portions that can be hooked to the upper and lower sides of the body portion 310 may be formed on the upper and lower sides of the support plate portion 110, respectively. These locking parts may perform the function of determining the upper and lower limits of the sliding movement when the sliding bed 100 moves up and down with respect to the rotating base 300.

Specifically, the first locking portion 111 formed on the upper side of the support plate portion 110 is bent rearward and/or lower from the top of the support plate portion 110 and is located at the upper edge of the body portion 310. Can be wrapped on the upper and rear sides.

In addition, the second locking portion 112 formed on the lower side of the support plate portion 110 is bent in a rearward and/or upper direction from the bottom of the support plate portion 110 and wraps the lower portion of the body portion 310. You can.

Here, since the extension frame 301 connected to the hook 400 is coupled to the lower side of the body portion 310, it is preferable that a locking end 311 be added to lock the second locking portion 112. The locking end 311 may have a predetermined gap with the extension frame 301 so that the second locking portion 112 can surround it. For this purpose, a part of the locking end 311 may be spaced forward with respect to the extension frame 301 extending downward to the body portion 310, or may be disconnected from the extension frame 301.

The distance (h2) between the ceiling portion of the first engaging portion 111 and the bottom portion of the second engaging portion 112 substantially corresponds to the height of the support plate portion 110, which is the height of the body portion 310. higher than (h1). The difference between the height h2 of the support plate 110 and the height h1 of the body 310 may mean an operating distance that the sliding bed 100 can move with respect to the rotating base 300.

Meanwhile, the distance from the rear of the support plate 110 to the inner surface of the locking portion is substantially larger than the thickness of the body 310, and this is related to the distance at which the sliding bed 100 can be moved in the forward and backward directions. In the description of the present invention, the front-back direction refers to the direction in which the body portion 310 and the support plate portion 110 are spaced apart and come closer.

A guide spacer 120 is disposed on the rear side of the support plate portion 110 in a manner that protrudes rearward, corresponding to the guide portion 320. The guide spacer 120 has a first function of guiding up and down sliding movement while moving along the guide part 320, a second function of guiding forward and backward movement, and a space between the body part 310 and the support plate part 110. A third function of controlling the spacing can be performed, and the movement of the sliding bed 100 will be discussed in more detail in the description of FIG. 5.

In addition, the sliding bed 100 may further include a functionalization unit 150 on the rear side, and various massage or stretching devices may be applied in addition to inversion movement and sliding movement.

In a first embodiment, the functionalization unit 150 may be made of a vibration device, and vibration may be transmitted to the front of the support plate unit 110 according to a control signal from a predetermined controller to provide a massage effect by vibration. .

In a second embodiment, the functionalization unit 150 may be composed of a heating device, and may operate a heating or cooling function according to a control signal from a controller to provide a predetermined temperature to a selected body part.

In a third embodiment, the functionalization unit 150 may be made of an air expansion member, and may be expanded or contracted by the operation of a predetermined controller and an air compressor to provide a massage function. When applying such an air expansion member, it will be possible to dramatically improve the spinal correction ability by rising from the user's neck or waist area and pulling it while hanging upside down. Note that the effect of traction and correction can be maximized when the application of such an air expansion member and the sliding movement of the sliding bed 100 are combined with an inverted exercise device.

Additionally, a deceleration unit 330 capable of controlling the speed of sliding movement of the sliding bed 100 may be further applied to the rotating base 300. The deceleration unit 330 is a known movement-resistant device or member such as a damper, friction value, or gear, and is applied at a predetermined time difference or at a slow speed when the rotating base 300 is reversed and rotated according to the degree of resistance. It may be possible to perform the function of pulling the upper half down.

Additionally, the body portion 310 may further include a predetermined elastic restoration device so that the sliding bed 100 can be restored to its set height. For example, downward restoring force may be provided so that the support plate portion 110 can move upward (based on the standby state) relative to the body portion 310 only when the user's load is applied. This elastic restoration device may also be considered to be formed integrally with the reduction unit 330.

Additionally, it may be considered that the body portion 310 and the sliding bed 100 further include a sliding drive device (not shown) to automatically and actively perform sliding movement in the up-down direction and/or forward-backward direction. . For example, various linear movement drive control devices such as a robot arm, rack and pinion, ball shaft and nut, and chain driven by a predetermined controller control signal may be applied.

The above embodiments can be applied additionally or interchangeably.

Figure 5 is a side view for explaining the operation of the inverted exercise device with improved functions of the present invention.

For convenience of explanation, the body portion 310 of the rotating base 300 disposed inside the sliding bed 100 is shown in perspective.

Figure 5(a) shows an upright and downward rotation state, and Figure 5(b) shows an inverted upward rotation state.

In (a) of FIG. 5, the user is in a waiting state before being seated or in a state of preparation while leaning on his back, and the sliding bed 100 is moved downward with respect to the pivoting base 300. Referring to FIG. 4, the first locking portion 111 of the sliding bed 100 is caught on the top of the body portion 310 and is connected to the lower side, more precisely, the lower end of the locking end 311 of the body portion 310 and the first locking portion 111 of the sliding bed 100. There is a separation space between the bottom surfaces of the two locking portions 112. This separation space will function as an operating distance (ℓ) by which the sliding bed 100 can be moved up and down, as will be described later.

As described above, the side plate portion 113 of the sliding bed 100 is disposed surrounding the side surface of the body portion 310, and the side plate portion 113 can perform a guide function for vertical sliding movement.

At this time, the end of the guide spacer 120 is in close contact with the front side of the body portion 310, and this guide spacer 120 determines the gap between the support plate portion 110 and the body portion 310. The end of the guide spacer 120 may contact the surface of the body portion 310 or the lower portion of the guide portion 320. In the upright state, the gap is defined as the first gap d1. In some cases, the first gap d1 may be set by the side plate portion 113 surrounding the body portion 310 from the rear side.

As shown in the illustrated embodiment, the guide portion 320 is inclined rearward so that the guide spacer 120 can follow it. This guide portion 320 is configured in the clearance space 321 into which the guide spacer 120 can be inserted and moved, and may preferably be formed by cutting and bending the plate of the body portion 310 toward the rear. As shown in the example, based on the standby state, the slope becomes more biased toward the rear as it moves upward. Accordingly, when the sliding bed 100 moves upward, the guide spacer 120 follows the guide portion 320 It moves to the rear and the gap decreases.

Figure 5(b) shows an inverted state in which the pivot base 300 is rotated at the pivot axis. Here, the definitions for up and down and forward and backward directions should be unified and used based on the atmospheric condition.

In a state where it is completely rotated upward, the rotation base 300 is caught by a rear stopper (not shown) provided on the rear support portion 220 and is flipped upside down. At this time, the sliding bed 100 moves upward with respect to the rotating base 300 due to the user's load and/or the self-weight of the sliding bed 100. As shown, the second locking portion 112 is caught by the locking end 311 of the body portion 310 to determine the limit of upward movement. Due to this condition, a gap equal to the operating distance (ℓ) occurs between the upper end of the body portion 310 and the first locking portion 111.

Meanwhile, the guide spacer 120 simultaneously moves rearward during the upward movement along the front surface of the guide portion 320, thereby forming a second gap d2 having a distance smaller than the first gap d1.

When the sliding bed 100 is rotated upward and reversed by the operation of the sliding bed 100, the sliding bed 100 seats the upper body and moves downward with friction, so it moves downward (based on the inverted state) with respect to the hanger 400 that fixes the foot. ), which acts as a force that pulls the upper body further.

In addition, as described above, in the case of the upside-down movement, it does not move completely perpendicular to the ground but is upright and inverted by forming a predetermined angle, so it is formed completely straight from the hanger 400 to the sliding bed 100. If the sliding bed 100 moves further rearward than in the previous case, the waist may bend further rearward. In other words, in this case, the upper body is closer to being upright in the direction of gravity than the lower body.

Through the above operation, the stretching effect can be maximized by pulling the upper body further away from the feet and at the same time allowing the lower back to be further extended.

When the above-described functionalization unit 150 operates along with the stretching and traction correction, the optimal effect can be achieved according to each purpose.

The inverted exercise device with the improved function according to the present invention as described above improves the conventional inverted and rotated inverted device and has a sliding structure capable of upward and downward traction to relax the spine, thereby providing the effect of stretching and correction. can be improved dramatically.

In addition, because forward and backward movement can occur in parallel with upward and downward movement, the force on the body during the inversion process can be further diversified.

In addition, the purpose of improving physical health can be flexibly adapted to the needs of various users by allowing the configuration of functionalization units such as vibration, heat, and expansion.

In the above, the present invention has been described in detail based on examples and accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the content described in the claims described later.
