Specific details for implementing the invention

[0024] A body-detachable portable chair according to the present invention will be described in detail below with reference to the attached drawings.

[0026] [Example 1-1] The present invention relates to a body-detachable portable chair, comprising: a buttock support member (10) having one surface in contact with the buttocks of a user and supporting the buttocks of a user; a first frame (100) having a portion connected to the buttock support member (10) and two portions each located on the back of the user's thigh; a second frame member (200) including a second frame (210) having an upper end hinged to the lower front of the first frame (100) and having a space formed inside; and a third frame (300) having an upper end hinged to the lower rear of the first frame (100) and inserted into the second frame (210) to move inside the second frame (210) according to the user's posture. It includes a third frame support member (310) that is installed inside the second frame (210) in a direction crossing the second frame (210) and supports the third frame (300) by contacting the bottom of the third frame (300) according to the user's posture to restrict the movement of the third frame (300).

[0027] [Example 1-2] The present invention relates to a body-removable portable chair, wherein in Example 1-1, the buttock support (10) is plate-shaped.

[0028] [Examples 1-3] The present invention relates to a body-removable portable chair, wherein in Example 1-1, the buttock support (10) includes a curved surface that is bent outward in correspondence with the user's buttocks.

[0029] [Examples 1-4] The present invention relates to a body-removable portable chair, wherein in Example 1-1, two buttock support portions (10) are individually spaced apart at a certain distance.

[0030] [Examples 1-5] The present invention relates to a body-removable portable chair, wherein in Example 1-1, one buttock support (10) is in contact with and supports the user's buttocks.

[0031] [Examples 1-6] The present invention relates to a body-removable portable chair. In Example 1-1, the buttock support (10) comprises a plate (10) and a cushion (12) formed on the surface of the plate (10) and in contact with the buttocks of the user.

[0032] The present invention relates to a portable chair that is worn on the body to support a sitting posture whenever and wherever necessary. More specifically, it relates to a body-detachable portable chair for agricultural use that is securely fixed to the user's lower body so as not to interfere with walking, while stably distributing and supporting body weight when seated to prevent musculoskeletal disorders.

[0033] In agricultural fields, it is common to have to work for long periods while squatting. Existing portable chairs or wheeled work chairs have the disadvantage of requiring manual movement during transport or being inconvenient to use on uneven ground. Additionally, chairs that simply hang from the buttocks wobble while walking, hindering mobility, and cause pressure on specific body parts when used for extended periods.

[0034] The present invention aims to provide a portable chair that allows a farmer to walk or work freely while wearing it, and provides sturdy support by adjusting the frame to the user's posture without any separate operation when seated. In particular, the present invention relates to a body-detachable portable chair that can secure an adjustment function tailored to the user's body type (leg length) and stability that prevents slipping even on slopes or dirt floors.

[0035] The body-removable portable chair according to the present invention includes a buttock support (10), a first frame (100), a second frame (200), a third frame (300), and a third frame support (310).

[0036] One side of the buttock support (10) is in contact with the user's buttocks and supports the user's buttocks.

[0037] The buttock support (10) may be formed in a plate shape. However, in order to support the user's buttocks, the buttock support (10) may not be formed with a horizontal flat surface, but may be configured to include a curved surface that is bent outward to correspond to the user's buttocks.

[0038] The buttock support (10) may be implemented in such a way that two are spaced apart at a certain distance from each other in correspondence with the user's buttocks, or formed as one to support both buttocks of the user.

[0039] The buttock support (10) can be manufactured from a single material having a certain degree of rigidity. For example, the buttock support (10) can be manufactured from synthetic resin.

[0040] As another example, the buttock support (10) may include a plate (10) and a cushion (12).

[0041] The plate (10) is manufactured from a material having a certain degree of rigidity, and the cushion part (12) can be manufactured from a general cushion. In the case of an embodiment in which the cushion part (12) includes the plate (10) and the cushion part (12), when a user uses the body-detachable portable chair according to the present invention, there is an effect of supporting the user's buttocks more comfortably.

[0042] The first frame (100) has a shape that extends to one side.

[0043] The first frame (100) can be manufactured from various types of materials, for example, the first frame (100) can be manufactured including at least one of metal and synthetic resin.

[0044] The angle of the first frame (100) can be changed according to the user's posture.

[0045] The second frame part (200) includes a second frame (210) in which the upper end is hinge-connected to the lower front end of the first frame (100) and a space is formed inside.

[0046] The angle between the first frame (100) and the second frame (210) can differ depending on the user's movement.

[0047] The third frame (300) is hinged at its upper end to the lower rear end of the first frame (100) and is inserted into the interior of the second frame (210), moving along the interior of the second frame (210) according to the user's posture. For example, when the user squats to sit, the third frame (300) moves downward along the interior of the second frame (210), and conversely, when the user stands, the third frame (300) moves upward along the interior of the second frame (210).

[0048] The third frame support (310) is installed inside the second frame (210) in a direction that crosses the second frame (210), and comes into contact with the bottom of the third frame (300) according to the user's posture, thereby restricting the movement of the third frame (300) inside the second frame (210). That is, the third frame support (310) comes into contact with the bottom of the third frame (300), thereby fixing the angle between the first frame (100) and the second frame (210), and allowing the user to sit on the buttock support (10).

[0049] The bottom of the second frame part (200) is in contact with the ground and supports the user's load.

[0050] The first frame (100), the second frame (210) of the second frame part (200), the third frame (300), and the third frame support part (310) described above are formed as a set, and when referred to as a set, two sets may be spaced apart in the width direction of the user's body.

[0052] [Example 2-1] The present invention relates to a body-removable portable chair, and in Example 1-1, includes a waist band portion (500) connected to the buttock support portion (10) and wrapped around and secured to the user's waist.

[0053] [Example 2-2] The present invention relates to a body-removable portable chair, wherein in Example 2-1, the waist band portion (500) comprises: a waist band (510) that wraps around the user's waist; and a connecting band (520) having one end connected to the waist band (510) and the other end hinge-connected to the buttock support portion (10).

[0054] [Example 2-3] The present invention relates to a body-removable portable chair. In Example 2-2, a waist loop (511) is formed at one end of the waist band (510) to which the other end of the waist band (510) is attached, a first waist fixing member (512) is formed at the other end of the waist band (510), and a second waist fixing member (513) is formed at the middle end of the waist band (510) to which the first waist fixing member (512) is attached.

[0055] [Example 2-4] The present invention relates to a body-detachable portable chair. In Example 2-1, the buttock support (10) includes a connecting member formed by a through hole, and the connecting band (520) is hinge-coupled to the connecting member.

[0056] [Example 2-5] The present invention relates to a body-detachable portable chair. In Example 2-1, the buttock support (10) has a groove formed at its end and holes formed through both sides of the groove, a pin is inserted into the holes, and the other end of the connecting band (520) is wrapped around the pin exposed through the groove, and the other end of the connecting band (520) is hinge-coupled to the buttock support (10).

[0057] The body-removable portable chair according to the present invention may further include a waist band portion (500).

[0058] The waist band (500) is connected to the buttock support (10) and wraps around and secures the user's waist, thereby having the effect of allowing the user to use the body-detachable portable chair according to the present invention more stably.

[0059] The waist band portion (500) is connected to the buttock support portion (10) and is located above the buttock support portion (10), and includes a waist band (510) and a connecting band (520).

[0060] The waistband (510) is a band that wraps around the user's waist.

[0061] The waistband (510) can be implemented in the form of a single strap. A waist loop (511) may be formed at one end of the waistband (510), and a first waist fixing member (512) may be formed at the other end of the waistband (510). In the present invention, the first waist fixing member (512) may be a female Velcro. A second waist fixing member (513) may be formed at the middle of the other end of the waistband (510) as a male Velcro that is coupled to the first waist fixing member (512). That is, the user can wear the waistband (510) by passing the other end of the waistband (510) through the waist loop (511) and then pulling to attach the first waist fixing member (512) and the second waist fixing member (513) to each other.

[0062] One end of the connecting band (520) is connected to the waist band (510), and the other end is hinge-connected to the buttock support (10). The connecting band (520) can also be implemented in the form of a strap.

[0063] Due to the relative positional difference between the waist band (510) and the buttock support (10), the connecting band (520) is inevitably extended in the upward and downward directions. The upper end of the connecting band (520) can be joined to the waist band (510) by a predetermined means, such as a thread, and the lower end can be joined to a connecting member formed on the buttock support (10).

[0064] The connecting member is a member located on the side of a hole formed through the buttock support (10), and the lower end of the connecting band (520) wraps around the connecting member to connect the buttock support (10) and the waist band (510) to each other.

[0065] However, when the connecting band (520) is hinge-connected to the connecting member, stress due to the user's movement is applied to the connecting member. As previously described, since the buttock support (10) is generally formed of synthetic resin, problems such as breakage may occur in the connecting member, which is also formed of synthetic resin, due to the stress applied to the connecting member. To resolve this, a groove is formed in the buttock support (10) instead of a hole, and holes may be formed through both sides of the groove of the buttock support (10). A pin is inserted into the hole, and a loop formed at the other end of the connecting band (520) is wrapped around the pin exposed in the groove, thereby allowing the connecting band (520) and the buttock support (10) to be hinge-connected to each other. The pin may be formed of a metal with relatively high rigidity. This method allows the user to separate the waist band (500) and the buttock support (10) by pulling out the pin in an emergency, so it has the effect of being easier to handle in an emergency situation compared to the embodiment using the connecting member described above. However, since the pin may be pulled out in an unintended situation, when the pin is used, a stopper may be additionally provided as a separate safety device that is inserted into the pin to prevent the pin from coming off.

[0067] [Example 3-1] The present invention relates to a body-detachable portable chair, wherein in Example 1-1, the second frame part (200) includes a second length adjustment frame (220) which is inserted into the second frame (210) and has its lower end exposed to the lower side of the second frame (210) so as to be movable along the second frame (210).

[0068] [Example 3-2] The present invention relates to a body-removable portable chair, wherein in Example 3-1, the second frame (210) has a plurality of length adjustment grooves (211) formed spaced apart and penetrating in an extended direction, and the second frame part (200) is inserted into or protrudes from the second length adjustment frame (220), and when protruded, is inserted into the length adjustment groove (211) to fix the position of the second length adjustment frame (220), and includes a position fixing part (230).

[0069] [Example 3-3] The present invention relates to a body-detachable portable chair, wherein in Example 3-2, the second frame part (200) includes an elastic part (240) positioned between the position fixing part (230) and the second length adjustment frame (220) to push the position fixing part (230) into the length adjustment groove (211).

[0070] In the present invention, the second frame part (200) is described in detail.

[0071] As previously explained, the second frame section (200) includes a second frame (210). In addition, the second frame section (200) may further include a second length adjustment frame (220).

[0072] The second length adjustment frame (220) can be inserted into the second frame (210) and configured to be movable along the second frame (210). The second length adjustment frame (220) can be exposed to the lower part of the second frame (210) where an internal space is formed.

[0073] The second length adjustment frame (220) itself is intended to vary the length of the second frame part (200) itself according to the user's leg length.

[0074] Even if the second length adjustment frame (220) is inserted into the second frame (210) and moves, its position must be fixed when the user uses it.

[0075] To this end, a plurality of length adjustment grooves (211) are formed spaced apart and penetratingly in the extended direction of the second frame (210), and the second frame part (200) may further include a position fixing part (230) that is inserted into or protrudes from the second length adjustment frame (220), and is inserted into the length adjustment groove (211) when protruded to fix the position of the second length adjustment frame (220).

[0076] A groove may be formed in a part of the second length adjustment frame (220), and a position fixing part (230) may be inserted into the groove so as to move inward along the groove or protrude outward. Since the position fixing part (230) must move only within the groove, the inner end of the position fixing part (230) is formed with a wider cross-sectional area than other parts, and the outer end of the groove may be formed with a step in a direction that narrows the area of ​​the groove so that the inner end of the position fixing part catches.

[0077] The user can adjust the length of the entire second frame part (200) by changing the position of the position fixing part (230) located in the length adjustment groove (211) by inserting and removing the position fixing part (230) through the length adjustment groove (211) according to their own leg length.

[0078] However, even if the user inserts the position fixing part (230) into the second length adjustment frame (220) through the length adjustment groove (211), it may be difficult to take the position fixing part (230) out of the second length adjustment frame (220). To solve this problem, the second frame part (200) may further include an elastic part (240).

[0079] The elastic part (240) is positioned between the position fixing part (230) and the second length adjustment frame (220), and when the position fixing part (230) is inserted into the second length adjustment frame (220) by an external force (user), it is compressed, and when the external force is released, it pushes the position fixing part (230) into the length adjustment groove (211).

[0080] The elastic part (240) may be a spring, but the present invention is not limited to the shape of the elastic part (240) as a spring, and the elastic part (240) may be implemented with other types of elastic materials.

[0081] Even if the position fixing part (230) is pushed outward from the second length adjustment frame (220) by the elastic part (240), the inner end of the position fixing part (230) is formed wider than the cross-sectional area of ​​the groove formed in the second length adjustment frame (220), so that the position fixing part (230) does not come out of the groove.

[0083] [Example 4-1] The present invention relates to a body-removable portable chair, and in Example 1-1, includes a leg band portion (600) connected to the second frame (210) and wrapping around and securing the user's leg.

[0084] [Example 4-2] The present invention relates to a body-detachable portable chair, wherein in Example 4-1, the leg band portion (600) comprises: a leg band having one end connected to the surface of the second frame (210); a leg hook formed on the surface of the second frame (210) to which the other end of the leg band is hooked; a first leg fixing member formed on the other end of the leg band; and a second leg fixing member formed on the middle of the leg band to be attached to the first leg fixing member.

[0085] [Example 4-3] The present invention relates to a body-detachable portable chair, wherein in Example 4-2, one of the first leg fixing member and the second leg fixing member includes a female Velcro, and the other includes a male Velcro.

[0086] The body-detachable portable chair according to the present invention may further include a leg band portion (600).

[0087] The leg band portion (600) is connected to the second frame (210) and serves to wrap around and secure the user's leg. The body-detachable portable chair according to the present invention allows the user to use the body-detachable portable chair according to the present invention more stably through the leg band portion (600).

[0088] The leg band portion (600) includes a leg band, a leg loop, a first leg fixing member, and a second leg fixing member.

[0089] The leg band is implemented in the form of a strap and can be manufactured from a material that is elastic or non-elastic. The leg band wraps around the user's legs, specifically the user's thighs.

[0090] The leg loop is formed on the surface of the second frame (210) and is the part where the other end of the leg band wrapped around the user's leg is attached. The leg loop can be made of a material having a certain degree of strength or more, such as synthetic resin or metal.

[0091] The first leg fixing member is formed at the other end of the leg band, and the second leg fixing member is formed at the middle of the leg band. The other end of the leg band is hooked onto the leg loop, and in this state, the first leg fixing member and the second leg fixing member are joined together so that tension of a certain degree or more can be maintained in the leg band.

[0092] When the first leg fixing member and the second leg fixing member are combined, any form can be realized; for example, one of the first leg fixing member and the second leg fixing member can be realized in the form of a female Velcro and the other in the form of a male Velcro.

[0094] [Example 5-1] The present invention relates to a body-detachable portable chair, and in Example 1-1, includes a friction force enhancing part (700) formed at the bottom of the second frame part (200) to contact the ground and improve friction with the ground.

[0095] [Example 5-2] The present invention relates to a body-removable portable chair, wherein in Example 5-1, the lower surface of the friction force enhancing part (700) is manufactured by including at least one of rubber, silicone, and synthetic resin.

[0096] [Example 5-3] The present invention relates to a body-removable portable chair, wherein in Example 5-1, the friction force enhancing part (700) includes a protrusion (710) formed to protrude downward.

[0097] As previously described, the portable chair according to the present invention has a second frame part (200) in contact with the ground to support the user's weight. Since the second frame part (200) itself is in the form of a frame, a frictional force of a certain degree or more is required between the bottom of the second frame part (200) and the ground in order to prevent the user from slipping while using the chair. To improve the frictional force between the bottom of the second frame part (200) and the ground, the body-detachable portable chair according to the present invention may further include a frictional force enhancing part (700).

[0098] The friction force enhancing part (700) is formed at the bottom of the second frame part (200) and comes into contact with the ground to enhance friction with the ground.

[0099] The friction enhancement part (700) can be implemented in various forms at the bottom of the second frame part (200).

[0100] For example, the friction enhancement part (700) is made of an elastic material and is formed separately from the second frame part (200) at the bottom of the second frame part (200) to enhance friction with the ground so that the user does not slip when using the portable chair according to the present invention.

[0101] As another example, the friction force enhancing part (700) is implemented in the form of a protrusion formed to protrude downward at the bottom of the second length adjustment frame (220) included in the second frame part (200), so that the user can likewise prevent slipping when using the portable chair according to the present invention.

[0103] [Example 6-1] The present invention relates to a body-detachable portable chair, and in Example 1-1, comprises: a fourth frame part (400) having one end hinge-connected to the lower end of the second frame part (200); and a foot-wearing part (800) connected to the other end of the fourth frame part (400) and worn on the user's foot.

[0104] [Example 6-2] The present invention relates to a body-removable portable chair, wherein in Example 6-1, the fourth frame part (400) comprises: a fourth-1 frame (410) having one end hinge-connected to the lower end of the second frame part (200); and a fourth-2 frame (420) slidably connected to the fourth-1 frame (410) and configured to be movable along the fourth-1 frame (410).

[0105] [Example 6-3] The present invention relates to a body-removable portable chair. In Example 6-2, the 4-1 frame (410) has a sliding groove formed along the direction of extension, and the other end of the 4-2 frame (420) has a sliding member formed that is inserted into the sliding groove and moves along the sliding groove.

[0106] [Example 6-4] The present invention relates to a body-removable portable chair, wherein in Example 6-2, one end of the 4-2 frame (420) is hinge-connected to the foot-mounting part (800).

[0107] The body-detachable portable chair according to the present invention may further include a fourth frame part (400) and a foot-mounting part (800).

[0108] The fourth frame part (400) and the foot wearing part (800) are parts that connect the lower part of the second frame part (200) to the user's foot.

[0109] One end of the fourth frame part (400) is hinge-connected to the lower end of the second frame part (200), and the other end is connected to the foot-wearing part (800).

[0110] A portion of the foot-wearing part (800) is connected to the other end of the fourth frame part (400) and is worn on the user's foot.

[0111] In the present invention, the reason the fourth frame part (400) and the foot attachment part (800) connect the lower part of the second frame part (200) to the user's foot is to allow the user of the portable chair according to the present invention to walk more conveniently when walking without using the chair. If the second frame part (200) and the user's foot are not connected, the second frame part (200) itself will dangle behind the user's leg, which would interfere with the user's walking. Furthermore, when the user takes a seated position to use the portable chair according to the present invention, the lower part of the second frame part (200) must be spaced a certain distance from the user's heel in order to sit stably.

[0112] The fourth frame section (400) may include the fourth-1 frame (410) and the fourth-2 frame (420).

[0113] One end of the 4-1 frame (410) is hinged to the bottom of the 2-frame section (200). The hinge connection of one end of the 4-1 frame (410) to the bottom of the 2-frame section (200) is intended to allow the 2-frame section (200) and the 4-frame section (400) to move freely according to the user's movement.

[0114] The 4-2 frame (420) is slidably coupled with the 4-1 frame (410) and configured to move along the 4-1 frame (410). That is, by adjusting the sliding distance between the 4-1 frame (410) and the 4-2 frame (420), it is possible to adjust the entire length of the 4th frame section (400).

[0115] For the 4-1 frame (410) and the 4-2 frame (420) to be slidably coupled to each other, a sliding groove or space may be formed in one of the two frames, and a sliding member inserted into the sliding groove may be formed in the other frame. In this embodiment, a sliding groove may be formed in the 4-1 frame (410), and a sliding member inserted into the sliding groove may be formed in the 4-2 frame (420).

[0116] One end of the 4-2 frame (420) can be hinged to the foot attachment part (800), and this is also intended to allow the user to walk more freely while wearing the portable chair according to the present invention. A hook is formed on one end of the 4-2 frame (420), and a loop on which the hook is attached can be formed on the foot attachment part (800). However, in addition to the method described above, one end of the 4-2 frame (420) can be hinged to the foot attachment part (800) in various other ways.

[0118] [Example 7-1] The present invention relates to a body-removable portable chair. In Example 6-1, the foot-wearing part (800) comprises: a connecting auxiliary part (810) which is positioned at the heel portion when worn by a user and is hinge-connected to the other end of the fourth frame part (400); a first strap part (820) which is connected to the connecting auxiliary part (810) in the form of a loop and wraps around the user's heel and sole; and a second strap part (830) which is connected to the first strap part (820) and wraps around the user's instep.

[0119] In the present invention, the foot-wearing part (800) is specified.

[0120] The footwear part (800) includes a connecting auxiliary part (810), a first strap part (820), and a second strap part (830).

[0121] The connecting auxiliary part (810) can be manufactured from a material having a certain degree of rigidity or greater, and when a user wears the portable chair according to the present invention, it is located at the heel portion and is hinge-connected to the other end of the fourth frame part (400). As previously explained, the detailed configuration of the fourth frame part (400) to which the connecting auxiliary part (810) is hinge-connected is the fourth-2 frame (420).

[0122] The first strap portion (820) is in the form of a loop and is connected to the connecting auxiliary portion (810), and is worn in such a way that the loop wraps around the user's heel and sole.

[0123] The second strap portion (830) is connected to the first strap portion (820) and is implemented in a form that wraps around the user's instep. The second strap portion (830) is equipped with a separate loop and a device such as Velcro so that it can be fitted to the user's foot size.

[0125] [Example 8-1] The present invention relates to a body-detachable portable chair. In Example 1-1, the second frame (210) has a first angle adjustment hole formed at the front and a second angle adjustment hole (213) formed at the rear that is aligned in height with the first angle adjustment hole. The third frame support member (310) includes a step forming a first height (H1) and a second height (H2). Depending on the user's operation, it is inserted into the first angle adjustment hole or inserted into the second angle adjustment hole (213), so that the first height (H1) portion is positioned inside the second frame (210) and the first height (H1) portion comes into contact with the third frame (300) to support the third frame (300), or the second height (H2) portion is positioned inside the second frame (210) and the second height (H2) portion comes into contact with the third frame (300) and It supports the third frame (300) by contacting it.

[0126] The third frame (300) is inserted into the second frame (210) and supports the user's weight by coming into contact with the third frame support (310). However, if the third frame support (310) is fixed, the degree to which the third frame (300) descends is fixed, which may cause inconvenience to the user in using the portable chair according to the present invention.

[0127] To prevent such problems, in the present invention, a first angle adjustment hole and a second angle adjustment hole (213) are formed through the front and rear of the second frame (210), and a third frame support member (310) is formed in a shape having a step difference that forms a first height and a second height, and depending on the user's operation, the position in which the third frame (300) is supported can be changed by inserting it into the first angle adjustment hole or into the second angle adjustment hole (213) inside the second frame (210).

[0128] More specifically, the step having a first height and a second height can be positioned in the front and rear directions, and more specifically, the relatively higher first height can be positioned in the front and the relatively lower second height can be positioned in the rear. The third frame support (310) can be inserted into the first angle adjustment hole or the second angle adjustment hole (213) inside the second frame (210) according to the user's operation. For example, the user can press the third frame support (310) protruding into the first angle adjustment hole to move its position so that a part of the third frame support (310) protrudes into the second angle adjustment hole (213). In this case, the first height portion located in the front is positioned inside the second frame (210) to support the bottom of the third frame (300), and accordingly, the angle between the first frame (100) and the second frame (210) can be increased.

[0129] Conversely, the user can press the third frame support (310) protruding into the second angle adjustment hole (213) to move the position so that a part of the third frame support (310) protrudes into the first angle adjustment hole. In this case, the second height portion located at the rear is positioned inside the second frame (210) to support the bottom of the third frame (300), and accordingly, the angle between the first frame (100) and the second frame (210) can be reduced.
