Description

load-bearing frame

[0001] The present invention relates to a frame, and more particularly, to a load-bearing frame.

[0002] A variety of frame types are commonly used to support loads. Examples include office desks and computer desks, as well as heated massage devices equipped with heated massage modules that allow users to lie down and use them.

[0003] These office desks, computer desks, and thermal massage devices improve user convenience as their load-bearing area increases. However, as the load-bearing area increases, the area occupied by the desk or thermal massage device also increases, making storage difficult and reducing space efficiency.

[0004] Korean Patent Publication No. 2022-0023098 discloses a computer desk for PC rooms equipped with a conventional sliding auxiliary table. This computer desk features a sliding auxiliary table that can be moved in and out according to the user's needs, thereby enhancing user convenience.

[0005] However, these auxiliary tables move along the step guide rails provided on the stand, and when the auxiliary table is pulled out, the load applied to the auxiliary table is supported only by these step guide rails, so it is difficult to place heavy objects on them, and there is a limitation that only light objects such as keyboards can be placed on them.

[0006] In other words, there is a need to develop a technology that can facilitate storage by reducing the load-bearing area during storage, and improve convenience of use by increasing the load-bearing area during use, while also stably supporting the user's body load.

[0007] (Patent Document 1) Korean Patent Publication No. 2022-0023098 (published on March 2, 2022)

[0008] The present invention is intended to solve the above problems, and the purpose of the present invention is to provide a load-bearing frame that is easy to store while reducing the load-bearing area during storage, and that is convenient to use while increasing the load-bearing area during use, while stably supporting the user's body load.

[0009] The tasks 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 to which the present invention pertains from the description below.

[0010] According to one aspect of the present invention, a load-bearing frame capable of switching between a first state in which a first support surface and a second support surface that support a load are arranged in a height direction and a second state in which the first support surface and the second support surface are arranged in a length direction is provided, wherein the load-bearing frame includes a main body portion provided with the first support surface, and an auxiliary portion movable in the length direction of the main body portion and provided with the second support surface, wherein the auxiliary portion is provided with a main support roller connected to the main body portion and an auxiliary support rail supported by the main body portion.

[0011] At this time, the auxiliary support rail may be provided with a first-first auxiliary guide section that moves the auxiliary part downward so that the auxiliary part, which is spaced apart from the ground, is settled on the ground during the process of moving the auxiliary part in the longitudinal direction to switch the use state of the auxiliary part.

[0012] At this time, a first downward slope may be formed along the height direction on the second support surface so that the auxiliary part moves downward during the process of moving in the longitudinal direction.

[0013] At this time, a first upward slope can be formed along the height direction in the first-first auxiliary guide section.

[0014] At this time, the auxiliary support rail may be provided with a 1-2 auxiliary guide section extending from the 1-1 auxiliary guide section.

[0015] At this time, a second downward slope can be formed along the height direction in the first-second auxiliary guide section.

[0016] At this time, the second downward slope may be configured to have a predetermined angle so that the first downward slope of the second support surface moves in a state where the auxiliary part is fixed on the ground and the auxiliary part moves further in the longitudinal direction.

[0017] At this time, the main body may be provided with a main support rail that provides a movement path of the auxiliary part and an auxiliary support roller that supports the load of the auxiliary part.

[0018] At this time, the main support rail is provided with a first main guide section arranged horizontally in the longitudinal direction, and the length of the first main guide section can be formed to be equal to the sum of the length of the first-1 auxiliary guide section and the length of the first-2 auxiliary guide section.

[0019] At this time, the main support rail may be provided with a second main guide section in which a third downward slope is formed so that the main support roller moves downward when the use state is switched from the second state to the first state, and the auxiliary support rail may be provided with a second auxiliary guide section so that the second support surface is arranged parallel to the ground when the main support roller moves downward along the second main guide section.

[0020] At this time, the main support rail may be provided with a third main guide section in which a fourth downward slope is formed so that the main support roller moves downward when the use state is switched from the first state to the second state, and the auxiliary support rail may be provided with a third auxiliary guide section so that the second support surface is extended in the longitudinal direction of the first support surface when the main support roller moves downward along the third main guide section.

[0021] At this time, in the first state, the second support surface is arranged on the first support surface at a second separation distance, the main support roller moves downward along the third main guide section at a second separation distance when the use state is switched from the first state to the second state, and the second support surface can move downward by the second separation distance when the main support roller moves downward along the third main guide section.

[0022] At this time, the slope of the third main guidance section and the slope of the third auxiliary guidance section can be formed to be the same.

[0023] According to the above configuration, the load-bearing frame according to one aspect of the present invention can be used in a switching state between a first state in which the first support surface and the second support surface that support the load are arranged in the height direction and a second state in which the first support surface and the second support surface are arranged in the length direction, so that the load-bearing area is reduced during storage, making storage easy, and the thermal massage module arranged under the first support surface of the main body can be stably protected, and even in the storage state, a thermal effect can be provided to the user through the heating member provided on the second support surface, and when in use, the load-bearing area is increased, improving the convenience of use, and the auxiliary part is provided with a main support roller that moves along the main body part and an auxiliary support rail supported by the main body part, so that the user's body load can also be stably supported.

[0038] FIG. 1 is a perspective view illustrating a state in which a load-bearing frame according to an embodiment of the present invention is arranged in a first state, FIG. 2 is a cross-sectional view of a load-bearing frame according to an embodiment of the present invention, wherein a first support surface and a second support surface are arranged in the first state, FIG. 3 is a perspective view illustrating a main body provided in a load-bearing frame according to an embodiment of the present invention, FIG. 4 is a perspective view illustrating a state in which a load-bearing frame according to an embodiment of the present invention is arranged in a second state, FIG. 5 is a cross-sectional view of a load-bearing frame according to an embodiment of the present invention, wherein a first support surface and a second support surface are arranged in the second state, and FIG. 6 is a perspective view of an auxiliary part provided in a load-bearing frame according to an embodiment of the present invention. Here, the X direction is a length direction, the Y direction is a width direction, and the Z direction is a height direction. In order to clearly describe the present invention, parts that are not related to the description are omitted from the drawings.

[0039] A load-bearing frame (10) according to one embodiment of the present invention can be switched between a first state (S1) in which a first support surface (11) and a second support surface (12) supporting a load are arranged in a height direction (Z), and a second state (S2) in which the first support surface (11) and the second support surface (12) are arranged in a length direction (X).

[0040] This load-bearing frame (10), as shown in FIGS. 1 and 2, includes a main body (100) having a first support surface (11), and an auxiliary body (200) that is movable in the longitudinal direction (X) of the main body (100) and has a second support surface (12).

[0041] At this time, as illustrated in FIG. 3, the main body (100) is provided with a main support rail (110) that provides a movement path of the auxiliary body (200) and an auxiliary support roller (120) that supports the load of the auxiliary body (200). As illustrated in FIGS. 4 to 6, the auxiliary body (200) is provided with a main support roller (210) that is connected to the main body (100) and an auxiliary support rail (220) that is supported by the main body (100). The main support roller (210) may be arranged to move along the main support rail (110) provided in the main body (100), and the auxiliary support rail (220) may be supported by the auxiliary support roller (120) provided in the main body (100).

[0042] A thermal massage module capable of providing thermal massage may be installed at the lower portion of the first support surface (11) of the main body (100). The thermal massage module may include a pressing portion equipped with a pressing member to pressurize a user, a driving portion equipped with a driving motor member that provides a driving force to adjust the height direction position of the pressing member, a transport portion equipped with a transport motor member that provides a driving force to move the body portion along the longitudinal direction, and a control portion that controls the operation of each portion.

[0043] The pressure member provided in this thermal massage module can massage the spine while moving in the longitudinal direction (X) along the user's spine, and can provide a massage effect at an appropriate temperature depending on the massaged location by heating or cooling the pressure member using the current supplied through the control unit.

[0044] At this time, the pressurized member may be configured to provide the user with a thermal steaming and massage effect by using not only high-temperature heat but also far-infrared rays.

[0045] The pressurizing member may be formed in a roller shape, but is not limited thereto, and various shapes and structures are possible as long as the pressurizing member is configured to rotate while moving in the longitudinal direction (X).

[0046] In addition, if the pressurized member is formed of a material such as ceramic, the massage effect can be improved as far infrared rays are generated during the use of the massage module. However, it is not necessarily limited to such materials, and it is also possible to form it of other materials as long as it can provide a massage effect by transmitting heat to the user's body.

[0047] Additionally, the transport unit may be equipped with a transport motor member that moves the pressure member in the user's longitudinal direction (X). Additionally, the transport unit may be equipped with a transport member that reciprocates the pressure member in the longitudinal direction (X).

[0048] The transfer motor member is provided with a transfer shaft member that rotates when current is supplied, and the transfer member is connected to the transfer shaft member and transmits rotational force according to the rotation of the transfer shaft member to move the pressure member.

[0049] The transfer member is connected to the pressure member and is used to transfer the pressure member in one or the other direction along the user's longitudinal direction (X) depending on the forward or reverse rotation of the transfer motor member.

[0050] The transport member may be selectively used as a transport belt, transport chain, or transport rope, but is not limited thereto, and various means of transporting an object using the driving force of the transport motor member, such as a lead screw or a rack and pinion, may be used.

[0051] In addition, the driving unit is provided with a driving motor member that provides driving force so that the height direction (Z) position of the pressing member is adjusted, and the control unit controls the operation of the driving motor member to adjust the height direction (Z) position of the pressing member, thereby adjusting the degree to which the pressing member presses the user.

[0052] At this time, when the load-bearing frame (10) is in the first state (S1), the second support surface (12) must be arranged above the first support surface (11) in the height direction (Z). This configuration protects the thermal massage module installed on the lower side of the first support surface (11) of the main body (100) in the first state (S1), and allows the user to sit on the second support surface (12) of the auxiliary part (200) and feel the thermal effect when the heating member installed in the auxiliary part (200) is exposed to the outside in the first state (S1). In addition, when the first support surface (11) and the second support surface (12) are arranged in the height direction (Z), the longitudinal length of the load-bearing frame (10) is reduced, thereby improving the ease of storage.

[0053] In addition, when the load-bearing frame (10) is in the second state (S2), the first support surface (11) and the second support surface (12) are arranged in the longitudinal direction (X), thereby increasing the area that can support the user's body, thereby improving the convenience of use.

[0054] In this state, the user's upper body is placed on the first support surface (11) of the main body (100) to receive a thermal massage through the thermal massage module, and the user's lower body is placed on the second support surface (12) of the auxiliary body (200) to provide a thermal effect to the lower body during the thermal massage process.

[0055] That is, the load-bearing frame (10) according to one embodiment of the present invention can be used in a first state (S1) in which the first support surface (11) and the second support surface (12) supporting the load are arranged in the height direction (Z) and a second state (S2) in which the first support surface (11) and the second support surface (12) are arranged in the length direction (X), so that the load-bearing area is reduced during storage, making storage easy, and the thermal massage module arranged under the first support surface (11) of the main body (100) can be stably protected, and a thermal effect can be provided to the user through the heating member provided on the second support surface (12) even in the storage state, and when used, the load-bearing area is increased, improving the convenience of use, and the auxiliary part (200) is provided with a main support roller (210) connected to the main body (100) and an auxiliary support rail (220) supported by the main body (100), so that the user's body load can also be stably supported. It works.

[0056] FIG. 7 is a cross-sectional view of an auxiliary part provided in a load-bearing frame according to one embodiment of the present invention, and FIGS. 8 to 10 are cross-sectional views illustrating a process in which a load-bearing frame according to one embodiment of the present invention is switched from a first state to a second state in use. FIG. 8 is a drawing illustrating a state in which an auxiliary support roller is arranged in a first auxiliary guide section of an auxiliary support rail, FIG. 9 is a drawing illustrating a state in which an auxiliary support roller is arranged at a boundary between a first auxiliary guide section and a first auxiliary guide section of an auxiliary support rail, and FIG. 10 is a drawing illustrating a state in which an auxiliary support roller is arranged at a boundary between a first auxiliary guide section and a third auxiliary guide section of an auxiliary support rail.

[0057] For example, as illustrated in FIG. 2, the auxiliary part (200) may be provided with a leg member (230) that is spaced apart from the ground (g) by a first distance (d1) in a first state (S1) and is placed in a fixed position on the ground (g) in a second state (S2).

[0058] That is, the first support surface (11) provided in the main body (100) is arranged at a predetermined height from the ground (g) along the height direction (Z) through the frame member (130) described later, and the second support surface (12) provided in the auxiliary part (200) can be arranged at a predetermined height from the ground (g) along the height direction (Z) through the leg member (230). With this configuration, the user can use the load-bearing frame without bending his / her back too much, thereby improving the convenience of use.

[0059] As shown in FIGS. 7 to 9, the auxiliary support rail (220) may be provided with a first-first auxiliary guide section (221a) that moves the auxiliary part (200) downward so that the auxiliary part (200) spaced apart from the ground (g) is settled on the ground (g) during the process of moving the auxiliary part (200) in the longitudinal direction (X) to switch the use state of the auxiliary part (200).

[0060] That is, when the use state is changed from the first state (S1) in which the first support surface (11) and the second support surface (12) supporting the load are arranged in the height direction (Z) to the second state (S2) in which the first support surface (11) and the second support surface (12) are arranged in the length direction (X), it is important for the user convenience that the first support surface (11) and the second support surface (12) are arranged horizontally. That is, when the use state is switched from the first state (S1) to the second state (S2), the height direction (Z) position of the second support surface (12) provided in the auxiliary part (200) must be adjusted, and if the first-first auxiliary guide section (221a) is provided in the auxiliary support rail (220), in the first state (S1), the auxiliary part (200) is spaced from the ground (g), but in the second state, the auxiliary part (200) is settled on the ground (g), so the height direction (Z) position of the second support surface (12) can be easily adjusted.

[0061] In particular, the height direction (Z) position of the second support surface (12) can be adjusted even without a separate configuration (height adjustment member, etc.) for adjusting the height direction (Z) position of the auxiliary part (200), so that the configuration of the load-bearing frame can be simplified.

[0062] This 1-1 auxiliary guidance section (221a) can form the 1st auxiliary guidance section (221) together with the 1-2 auxiliary guidance section (221b) described later.

[0063] As shown in FIGS. 7 to 9, as the auxiliary part (200) moves in the longitudinal direction (X), a first downward slope (θD1) can be formed on the second support surface (12) along the height direction (Z) so that the auxiliary part (200) moves downward in the process of the first-first auxiliary guide section (221a) being supported by the auxiliary support roller (120).

[0064] That is, as described above, even if a separate configuration for adjusting the height direction (Z) position of the auxiliary part (200) is not provided, in the process of the auxiliary part (200) moving in the longitudinal direction (X) to switch the use state of the load-bearing frame (10), the first downward slope (θD1) is formed on the second support surface (12) through the first-first auxiliary guide section (221a), and the height direction (Z) position is gradually lowered, and through this process, the second support surface (12) can be arranged horizontally with the first support surface (11).

[0065] In addition, this first-first auxiliary guide section (221a) allows the auxiliary part (200) to move to the upper part of the main body (100) while being separated from the ground (g) when the use state is switched from the second state (S2) to the first state (S1).

[0066] As described above, the auxiliary part (200) may be provided with a leg member (230) that is spaced apart from the ground (g) by a first distance (d1) in the first state (S1) and is placed in a fixed position on the ground (g) in the second state (S2). When the leg member (230) is provided in the auxiliary part (200) in this way, the leg member (230) is spaced apart from the ground (g) in the first state (S1), but the leg member (230) can be placed in a fixed position on the ground (g) in the second state, and when the first-first auxiliary guide section (221a) is provided in the auxiliary support rail (220), the position in the height direction (Z) of the second support surface (12) can be easily adjusted in the process of the auxiliary part (200) moving in the longitudinal direction (X).

[0067] In particular, the height direction (Z) position of the second support surface (12) can be adjusted even without a separate configuration (height adjustment member, etc.) for adjusting the height direction (Z) position of the leg member (230), so that the configuration of the load-bearing frame can be simplified.

[0068] As illustrated in Fig. 7, a first upward slope (θU1) can be formed along the height direction (Z) in the first-first auxiliary guide section (221a).

[0069] That is, since the first upward slope (θU1) is formed while the first-first auxiliary guide section (221a) is supported by the auxiliary support roller (120) whose height direction (Z) position is fixed, the height of the second support surface (12) decreases as the auxiliary part (200) moves in the longitudinal direction (X), and through this, the second support surface (12) can be arranged horizontally with the first support surface (11).

[0070] At this time, the first upward slope (θU1) of the 1-1 auxiliary guide section (221a) can be formed at an angle that allows the height of the second support surface (12) to be quickly adjusted without causing interference with the first support surface (11) of the main body (100) during the process of the auxiliary part (200) moving in the longitudinal direction (X).

[0071] As illustrated in FIGS. 7 and 10, the auxiliary support rail (220) may be provided with a 1-2 auxiliary guide section (221b) extending from the 1-1 auxiliary guide section (221a), and this 1-2 auxiliary guide section (221b) may be extended from the 1-1 auxiliary guide section (221a) so that when the auxiliary member (200) moves further in the longitudinal direction (X) while the leg member (230) is secured to the ground (g), the first downward slope (θD1) of the second support surface (12) is maintained constant.

[0072] That is, when the auxiliary part (200) moves in the longitudinal direction (X) through the 1-1 auxiliary guide section (221a) of the auxiliary support rail (220) and the leg member (230) is settled on the ground (g), the first downward slope (θD1) of the second support surface (12) of the auxiliary part (200) is fixed to a constant state, and in this state, the auxiliary part (200) moves further in the longitudinal direction (X) through the 1-2 auxiliary guide section (221b) of the auxiliary support rail (220) so that interference between the auxiliary part (200) and the first support surface (11) does not occur.

[0073] FIG. 11 is a side view illustrating a main support rail provided in a load-bearing frame according to one embodiment of the present invention.

[0074] At this time, as illustrated in FIG. 3, the main body (100) may be provided with a main support rail (110) that provides a movement path of the auxiliary part (200) and an auxiliary support roller (120) that supports the load of the auxiliary part (200), and as illustrated in FIG. 11, the main support rail (110) may be provided with a first main guide section (111) that is horizontally arranged in the longitudinal direction (X). In addition, as illustrated in FIG. 7, the length (LM) of the first main guide section (111) may be formed to be equal to the sum of the length (L1) of the 1-1 auxiliary guide section (221a) and the length (L2) of the 1-2 auxiliary guide section (221b). By configuring it in this way, not only can the auxiliary part (200) move smoothly in the longitudinal direction (X), but also the leg member (230) can be smoothly settled on the ground (g) during the process of moving the auxiliary part (200) in the longitudinal direction (X).

[0075] As illustrated in Fig. 7, a second downward slope (θD2) may be formed along the height direction (Z) in the first-second auxiliary guide section (221b). This second downward slope (θD2) may be configured to have a predetermined angle so that when the auxiliary part (200) is further moved in the longitudinal direction (X) while the auxiliary part (200) is settled on the ground (g), the first downward slope (θD1) of the second support surface (12) moves in a state in which it is constantly maintained. That is, as described above, when the auxiliary part (200) moves in the longitudinal direction (X) through the 1-1 auxiliary guide section (221a) of the auxiliary support rail (220) and the leg member (230) is settled on the ground (g), the first downward slope (θD1) of the second support surface (12) of the auxiliary part (200) is constantly fixed, and in this state, the auxiliary part (200) moves further in the longitudinal direction (X) through the 1-2 auxiliary guide section (221b) of the auxiliary support rail (220), thereby preventing interference between the auxiliary part (200) and the first support surface (11).

[0076] In order to ensure that the first downward slope (θD1) of the second support surface (12) of the auxiliary part (200) is constantly fixed during the process of the auxiliary part (200) moving further in the longitudinal direction (X), a second downward slope (θD2) is formed in the 1-2 auxiliary guide section (221b). This second downward slope (θD2) is an angle formed based on the second support surface (12) of the auxiliary part (200), and during the process of the auxiliary part (200) moving further in the longitudinal direction (X), the 1-2 auxiliary guide section (221b) is arranged parallel to the ground (g), thereby enabling additional movement of the auxiliary part (200) in the longitudinal direction (X) while the first downward slope (θD1) of the second support surface (12) is constantly fixed.

[0077] As illustrated in Fig. 11, the main support rail (110) is provided with a second main guide section (112) having a third downward slope (θD3) formed therein so that the main support roller (210) moves downward when the use state is switched from the second state (S2) to the first state (S1). With this configuration, when the switch to the first state (S1) is completed, the main support roller (210) moves downward along the second main guide section (112), so that the second state (S2) can be stably maintained without being arbitrarily released.

[0078] Additionally, as illustrated in FIG. 7, the auxiliary support rail (220) may be provided with a second auxiliary guide section (222) so that the second support surface (12) is arranged parallel to the ground (g) when the main support roller (210) moves downward along the second main guide section (112).

[0079] For example, this second auxiliary guide section (222) can be arranged parallel to the ground (g), and when the second auxiliary guide section (222) is provided, the second support surface (12) is arranged parallel to the ground (g), so that the user can sit on the second support surface (12) in the first state (S1) and feel the thermal effect while using the load-bearing frame (10).

[0080] As shown in Fig. 11, the second main guide section (112) may be provided with a main prevention protrusion (112a) to prevent the main support roller (210) from being arbitrarily detached.

[0081] In this way, when the main prevention protrusion (112a) is provided, even if an arbitrary external force is applied in the first state (S1), the first state (S1) is not arbitrarily released, and in order for the user to switch the usage state to the second state (S2), only when an external force is applied that causes the main support roller (210) to move beyond the main prevention protrusion (112a), the usage state can be switched from the first state (S1) to the second state (S2), thereby enabling stable use.

[0082] As shown in Fig. 7, the second auxiliary guide section (222) may be provided with an auxiliary prevention protrusion (222a) to prevent the auxiliary support roller (120) from being arbitrarily detached.

[0083] As described above, the second main guide section (112) is provided with a main prevention protrusion (112a) to prevent the main support roller (210) from being accidentally detached, and the second auxiliary guide section (222) is also provided with an auxiliary prevention protrusion (222a) to prevent the auxiliary support roller (120) from being accidentally detached. That is, even if an arbitrary external force is applied in the first state (S1), the first state (S1) is not arbitrarily released, and in order for the user to switch the usage state to the second state (S2), the main support roller (210) must move beyond the main prevention protrusion (112a) and the auxiliary support roller (120) must move beyond the auxiliary prevention protrusion (222a) only when an external force is applied, thereby allowing the usage state to be switched from the first state (S1) to the second state (S2), thereby enabling stable usage.

[0084] As illustrated in FIG. 11, the main support rail (110) may be provided with a third main guide section (113) in which a fourth downward slope (θD4) is formed so that the main support roller (210) moves downward when the use state is switched from the first state (S1) to the second state (S2), and the auxiliary support rail (220) may be provided with a third auxiliary guide section (223) so that the second support surface (12) is extended in the longitudinal direction (X) of the first support surface (11) when the main support roller (210) moves downward along the third main guide section (113).

[0085] That is, in order to enable stable use in the second state (S2), the second support surface (12) needs to be extended in the longitudinal direction (X) from the first support surface (11), and for this purpose, the main support rail (110) is provided with a third main guide section (113) having a fourth downward slope (θD4). That is, when the main support roller (210) of the auxiliary part (200) passes through the third main guide section (113), the height of the auxiliary part (200) is lowered. At this time, in order for the height of the auxiliary part (200) to be lowered, a section in which the height of the auxiliary part (200) can be lowered is also required in the auxiliary support rail (220) supported by the auxiliary support roller (120). As described above, when the third auxiliary guide section (223) is provided, interference by the auxiliary support roller (120) is prevented when the height of the auxiliary part (200) is lowered while the main support roller (210) passes through the third main guide section (113), so that the height of the auxiliary part (200) is smoothly lowered, and the second support surface (12) can be extended and arranged in the longitudinal direction (X) of the first support surface (11) in the second state (S2).

[0086] As illustrated in FIG. 2, in the first state (S1), the second support surface (12) is positioned on the first support surface (11) at a second separation distance (d2), and as illustrated in FIG. 5, the main support roller (210) moves downward along the third main guide section (113) at a second separation distance (d2) when the use state is switched from the first state (S1) to the second state (S2), and the second support surface (12) can move downward by the second separation distance (d2) when the main support roller (210) moves downward along the third main guide section (113).

[0087] That is, while the auxiliary member (200) moves backward in the longitudinal direction (X), the main support roller (210) passes through the first main guide section (111), while the auxiliary support roller (120) supports the 1-1 auxiliary guide section (221a), the leg member (230) is settled on the ground (g), and while the auxiliary member (200) moves further while the leg member (230) is settled on the ground (g), the auxiliary support roller (120) supports the 1-2 auxiliary guide section (221b), so that the first downward slope (θD1) of the second support surface (12) is maintained constant, thereby preventing interference with the first support surface (11).

[0088] However, the rear of the auxiliary part (200) in the longitudinal direction (X), that is, the height of the front of the auxiliary part (200) in the longitudinal direction (X) while the leg member (230) is fixed on the ground (g), needs to be lowered, and for this purpose, in the first state (S1), when the second support surface (12) is positioned on the first support surface (11) at a distance of the second distance (d2), the main support roller (210) moves downward along the third main guide section (113) at the time of switching the use state from the first state (S1) to the second state (S2), and the second support surface (12) is also configured to move downward by the second distance (d2) when the main support roller (210) moves downward along the third main guide section (113), thereby smoothly lowering the front height of the auxiliary part (200) and the second support surface (12) is positioned at a distance of the first support surface (11) at the distance of the second distance (d2). It can be extended in the direction (X).

[0089] At this time, the second separation distance (d2) can be formed to be the same as the first separation distance (d1).

[0090] As illustrated in FIGS. 7 and 11, the slope of the third main guide section (113) and the slope of the third auxiliary guide section (223) can be formed to be the same. By configuring in this way, when the height of the auxiliary section (200) is lowered in the process of the main support roller (210) moving along the third main guide section (113), interference by the auxiliary support roller (120) can be prevented, and when the height of the auxiliary section (200) is lowered, the main support roller (210) is supported by the third main guide section (113) and at the same time, the auxiliary support roller (120) supports the third auxiliary guide section (223), thereby enabling stable movement of the auxiliary section (200).

[0091] As illustrated in FIG. 2, the main body (100) is provided with a frame member (130) supported on the ground (g), and the leg member (230) is provided with a wheel (231). In a first state (S1), the wheel (231) is arranged to be spaced apart from the ground (g) by a first distance (d1), and as illustrated in FIG. 5, in a second state (S2), the wheel (231) can be placed to be fixed on the ground (g).

[0092] This frame member (130) allows the first support surface (11) of the main body (100) to be placed at a predetermined height from the ground (g) along the height direction (Z), thereby enabling the user to use the load-bearing frame without having to bend the waist too much, thereby improving the convenience of use.

[0093] In this configuration, since the wheel (231) is positioned at a first distance (d1) from the ground (g) in the first state (S1), when the use state is switched to the second state (S2), the wheel (231) can be stably placed on the ground (g), and stable movement is possible by the wheel (231) while the leg member (230) is placed on the ground (g).

[0094] As described above, the load-bearing frame (10) according to one embodiment of the present invention can be used in a first state (S1) in which the first support surface (11) and the second support surface (12) supporting the load are arranged in the height direction (Z) and a second state (S2) in which the first support surface (11) and the second support surface (12) are arranged in the length direction (X), so that the load-bearing area is reduced during storage, making storage easy, and the thermal massage module arranged under the first support surface (11) of the main body (100) can be stably protected, and a thermal effect can be provided to the user through the heating member provided on the second support surface (12) even in the storage state, and when in use, the load-bearing area is increased, improving the convenience of use, and the auxiliary part (200) is provided with a main support roller (210) connected to the main body (100) and an auxiliary support rail (220) supported by the main body (100), so that the user's body load can be stably supported. You will be able to support it.

[0095] Although one embodiment of the present invention has been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
