Description

Load-bearing frame with height-adjustable member

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

[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] Korean Patent Publication No. 2022-0075603 discloses a conventional massage device. This massage device includes an auxiliary member that supports the user's lower body, and a lifting / lowering member that adjusts the height of the auxiliary member.

[0007] However, these massage devices have limitations in miniaturizing and reducing weight as they are equipped with a motor or cylinder that provides driving force to adjust the height of the auxiliary part.

[0008] That is, when storing, the load-bearing area decreases, making storage easier, and when using, the load-bearing area increases, improving convenience of use while stably supporting the user's body weight. There is a need to develop technology that can be miniaturized and lightweight.

[0010] (Patent Document 2) Korean Patent Publication No. 2022-0075603 (published on June 8, 2022)

[0011] 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 improves the convenience of use while increasing the load-bearing area during use, and can stably support the user's body load, and is miniaturized and lightweight.

[0012] 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.

[0013] 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, and a load-bearing frame is provided in which a height-adjusting member is provided in the auxiliary portion so that the height of the auxiliary portion is lowered by using the load of the auxiliary portion when the use state is switched from the first state to the second state.

[0014] At this time, the height adjustment member may include a rotating bracket that rotates in one direction so that the height of the auxiliary part is lowered when a load is applied to the auxiliary part.

[0015] At this time, the height adjustment member further includes a fixed bracket connected to the auxiliary part, and the rotation bracket can be rotatably connected to the fixed bracket.

[0016] At this time, the fixed bracket may be provided with a rotation shaft so that the rotation bracket can rotate, and the rotation bracket may be provided with a through hole through which the rotation shaft passes.

[0017] At this time, the fixed bracket may be provided with a support plate that supports the rotating bracket that rotates in one direction.

[0018] At this time, the above-mentioned rotating bracket may be provided with a contact plate supported by the above-mentioned support plate.

[0019] At this time, the height adjustment member is provided with a contact point that contacts the ground in the first state, and the center of rotation of the rotation bracket can be positioned at a first distance in the longitudinal direction from the vertically above the contact point.

[0020] At this time, the above-mentioned rotation bracket can be rotated in the other direction so that the height of the auxiliary part increases when the use state is switched from the second state to the first state.

[0021] At this time, in the second state, the center of gravity of the rotation bracket may be spaced apart from the rotation center of the rotation bracket by a second distance in the longitudinal direction.

[0022] At this time, the above-mentioned rotary bracket may be provided with an extension rib that is supported in contact with the ground in the second state.

[0023] At this time, the height adjustment member may be provided with an auxiliary roller that is supported in contact with the ground in the second state.

[0024] At this time, the height adjustment member may be provided with an elastic member that applies elastic force so that the rotation bracket rotates in the other direction when the use state is switched from the second state to the first state.

[0025] At this time, one side of the elastic member is connected to the auxiliary part, the other side of the elastic member is connected to the rotation bracket, and the elastic member can be elastically deformed in the process of the rotation bracket rotating in one direction when the use state is changed from the first state to the second state.

[0026] 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 a thermal effect can be provided to the user through the heating member provided on the second support surface even in the storage state, and when in use, the load-bearing area is increased, improving the convenience of use, and the auxiliary part is provided with a height adjustment member so that the user's body load can also be stably supported, and since this height adjustment member adjusts the height of the auxiliary part using the load of the auxiliary part, a separate driving member that provides a driving force is not required, making miniaturization and weight reduction possible.

[0027] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

[0037] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts irrelevant to the description are omitted in the drawings, and the same reference numerals designate identical or similar components throughout the specification.

[0038] The words and terms used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, but should be interpreted in a way that is consistent with the technical idea of ​​the present invention, in accordance with the principles by which the inventor can define terms and concepts in order to best explain his or her invention.

[0039] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings correspond to a preferred embodiment of the present invention, and do not represent all of the technical ideas of the present invention, so there may be various equivalents and modified examples that can replace the configuration at the time of filing of the present invention.

[0040] In this specification, terms such as “include” or “have” are intended to describe the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0041] Fig. 1 is a side view illustrating a state in which a load-bearing frame according to one embodiment of the present invention is arranged in a first state, and Fig. 2 is a side view illustrating a state in which a load-bearing frame according to one embodiment of the present invention is arranged in a second state. Here, the X direction is the length direction, the Y direction is the width direction, and the Z direction is the height direction. In order to clearly explain the present invention, parts that are not related to the explanation are omitted from the drawings.

[0042] 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).

[0043] 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).

[0044] 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 pressure unit having a pressure member for applying pressure to a user, a drive unit having a drive motor member for providing a driving force to adjust the height direction position of the pressure member, a transport unit having a transport motor member for providing a driving force to move the body unit along the longitudinal direction, and a control unit for controlling the operation of each unit.

[0045] 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.

[0046] 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.

[0047] 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).

[0048] 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.

[0049] 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).

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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. To this end, the auxiliary part (200) is provided with a height adjustment member (210) that uses the load of the auxiliary part (200) to lower the height of the auxiliary part (200) when the use state is switched from the first state (S1) to the second state (S2).

[0056] 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.

[0057] 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 even in the storage state, a thermal effect can be provided to the user through the heating member provided in the second support surface (12), and when in use, the load-bearing area is increased, improving the convenience of use, and the auxiliary part (200) is provided with a height adjustment member (210) so that the user's body load can be stably supported, and in particular, this height adjustment member (210) uses the load of the auxiliary part (200). Since the height of the auxiliary part (200) is adjusted, a separate driving part that provides driving force is not required, enabling miniaturization and weight reduction.

[0058] FIG. 3 is a side view showing a state in which a height adjustment member provided in a load-supporting frame according to one embodiment of the present invention is arranged in a first state, FIG. 4 is a side view showing a state in which a height adjustment member provided in a load-supporting frame according to one embodiment of the present invention is arranged in a second state, FIG. 5 is a perspective view of a height adjustment member provided in a load-supporting frame according to one embodiment of the present invention, FIG. 6 is an enlarged side view of a height adjustment member provided in a load-supporting frame according to one embodiment of the present invention, and FIG. 7 is an exploded perspective view of a height adjustment member provided in a load-supporting frame according to one embodiment of the present invention.

[0059] As shown in FIGS. 3 and 4, the height adjustment member (210) may include a rotation bracket (211) that rotates in one direction (a) so that the height of the auxiliary part (200) is lowered when a load is applied to the auxiliary part (200).

[0060] The first support surface (11) provided in the main body (100) is arranged at a predetermined height from the ground (g) in the height direction (Z) through a separate frame member, and the second support surface (12) provided in the auxiliary part (200) can also be arranged at a predetermined height from the ground (g) in the height direction (Z) through a separate leg member. With this configuration, the user can use the load-bearing frame without bending his / her back too much, thereby improving the convenience of use.

[0061] However, 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 convenience of the user that the first support surface (11) and the second support surface (12) are arranged horizontally.

[0062] 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 as illustrated in FIGS. 3 and 4, when the load of the auxiliary part (200) is applied to the height adjustment member (210) in the process of switching the use state from the first state (S1) to the second state (S2), the rotation bracket (211) rotates in one direction (a) and the height of the auxiliary part (200) is lowered, so that the first support surface (11) and the second support surface (12) are arranged horizontally in the second state (S2), thereby improving the convenience of use. In addition, since the height adjustment member (210) adjusts the height of the auxiliary part (200) by using the load of the auxiliary part (200), a separate driving part that provides driving force is not required, thereby enabling miniaturization and lightweighting.

[0063] As shown in FIGS. 5 to 7, the height adjustment member (210) further includes a fixed bracket (212) connected to the auxiliary part (200), and the rotation bracket (211) can be rotatably connected to the fixed bracket (212).

[0064] In a state where the fixed bracket (212) is connected to the auxiliary part (200), the rotation bracket (211) is rotatably connected to the fixed bracket (212). A fixed plate (212a) may be provided on one side and the other side in the longitudinal direction (X) so that the fixed bracket (212) is connected to the auxiliary part (200).

[0065] That is, since the fixed bracket (212) is stably fixed to the auxiliary part (200) and the rotation bracket (211) is rotatably connected to the fixed bracket (212), the rotation bracket (211) can stably rotate when the use state is switched from the first state (S1) to the second state (S2), thereby improving structural stability.

[0066] As shown in Fig. 7, the fixed bracket (212) may be provided with a rotation shaft (212b) so that the rotation bracket (211) can rotate, and the rotation bracket (211) may be provided with a through hole (211a) through which the rotation shaft (212b) is disposed.

[0067] Such a fixed bracket (212) may be provided with a connecting plate (212c) to which a rotation shaft (212b) is connected. Accordingly, the rotation shaft (212b) may be fixed to the connecting plate (212c) while penetrating the through hole (211a) of the rotation bracket (211). In addition, the rotation shaft (212b) may be provided with a bush (bs) to ensure smooth rotation of the rotation bracket (211).

[0068] As the rotary shaft (212b) is provided in this way, the rotary bracket (211) can rotate stably, and since the rotary shaft (212b) is fixed to the fixed bracket (212) while penetrating the through hole (211a) of the rotary bracket (211), structural stability is improved.

[0069] As shown in FIGS. 6 and 7, the fixed bracket (212) may be provided with a support plate (212d) that supports a rotation bracket (211) that rotates in one direction (a).

[0070] That is, in the process of switching the use state from the first state (S1) to the second state (S2), the rotation bracket (211) rotates in one direction (a) and the height of the auxiliary part (200) is lowered, and when the use state switch to the second state (S2) is completed, the support plate (212d) supports the rotation bracket (211) and is configured so that the rotation bracket (211) no longer rotates.

[0071] By configuring it in this way, even if a user's load is applied to the auxiliary part (200) in the second state (S2), the rotation bracket (211) no longer rotates, thereby enabling stable support.

[0072] As illustrated in FIGS. 6 and 7, the rotation bracket (211) may be provided with a contact plate (211b) supported by a support plate (212d). When the transition to the second state (S2) is completed, the rotation bracket (211) is configured to no longer rotate while the contact plate (211b) is supported by the support plate (212d).

[0073] At this time, the contact plate (211b) may be in surface contact with the support plate (212d) so that the auxiliary part (200) can stably support the user's load. For example, the rotation bracket (211) may include a pair of unit rotation brackets that are arranged to face each other along the width direction (Y), and the contact plate (211b) may be configured to connect the pair of unit rotation brackets, and this configuration improves the structural stability of the rotation bracket (211).

[0074] Additionally, the main roller (MR) to be described later can be rotatably connected while being placed between a pair of unit rotation brackets.

[0075] In addition, the connecting plate (212c) provided on the fixed bracket (212) may include a pair of unit connecting plates that are arranged opposite each other along the width direction (Y), and each unit rotating bracket may be rotatably connected to each unit connecting plate.

[0076] As illustrated in FIG. 3, the height adjustment member (210) is provided with a contact point (C) that contacts the ground (g) in a first state (S1), and the rotation center (O) of the rotation bracket (211) can be spaced apart from the vertically above the contact point (C) by a first distance (d1) in the longitudinal direction (X).

[0077] That is, in the first state (S1), the height adjustment member (210) is provided with a contact point (C) that contacts the ground (g), and the rotation center (O) of the rotation bracket (211) is positioned at a first separation distance (d1) in the longitudinal direction (X) from the vertically above the contact point (C), so that when the load of the auxiliary part (200) is applied, the repulsive force of the ground (g) is applied to the contact point (C), and thus a moment having a magnitude corresponding to the product of the repulsive force of the ground (g) and the first separation distance (d1) is generated, and through this moment, the rotation bracket (211) rotates in one direction (a), thereby lowering the height of the auxiliary part (200).

[0078] Accordingly, a separate driving unit that provides driving force to adjust the height of the auxiliary unit (200) is not required, enabling miniaturization and weight reduction.

[0079] At this time, the rotation bracket (211) may be equipped with a main roller (MR), and in this case, the contact point (C) may be arranged at a portion where the main roller (MR) contacts the ground (g). This main roller (MR) reduces frictional resistance with the ground (g) so that the auxiliary part (200) can easily move during the process of switching the use state from the first state (S1) to the second state (S2). In addition, the main roller (MR) may be arranged to contact the ground (g) so that the auxiliary part (200) can easily move during the process of switching the use state from the second state (S2) to the first state (S1). The main roller (MR) may be rotatably connected while being arranged between a pair of unit rotation brackets described above. In addition, the rotation bracket (211) may be equipped with a main shaft (MS) so that the main roller (MR) can rotate. In addition, the height adjustment member (210) may be provided with a cover (CV) that covers the joint portion of the rotation bracket (211) and the main roller (MR).

[0080] As shown in FIGS. 3 and 4, the rotation bracket (211) can rotate in the other direction (b) so that the height of the auxiliary part (200) increases when the use state is switched from the second state (S2) to the first state (S1).

[0081] As described above, when the load of the auxiliary part (200) is applied to the height adjustment member (210) in the process of switching the use state from the first state (S1) to the second state (S2), the rotation bracket (211) rotates in one direction (a) so that the height of the auxiliary part (200) is lowered, and thus, when the use state is switched from the second state (S2) to the first state (S1), the rotation bracket (211) rotates in the other direction (b) so that the height of the auxiliary part (200) is raised.

[0082] As illustrated in FIG. 4, in the second state (S2), the center of gravity (K) of the rotation bracket (211) can be spaced apart from the rotation center (O) of the rotation bracket (211) by a second distance (d2) in the longitudinal direction (X).

[0083] That is, in order to switch the use state from the second state (S2) to the first state (S1), the height of the auxiliary part (200) must rise. This height rise of the auxiliary part (200) can be achieved through a separate rail structure while the auxiliary part (200) moves in the longitudinal direction (X), or can be achieved by the user directly lifting the auxiliary part (200).

[0084] At this time, when the height of the auxiliary part (200) rises, the rotation bracket (211) that has rotated in one direction (a) rotates in the other direction (b) due to gravity. That is, when gravity is applied to the center of gravity (K) of the rotation bracket (211), a moment having a size corresponding to the product of gravity and the second separation distance (d2) is generated, and through this moment, the rotation bracket (211) supports the auxiliary part (200) that has increased in height while rotating in the other direction (b).

[0085] Accordingly, a separate driving unit that provides driving force to adjust the height of the auxiliary unit (200) is not required, enabling miniaturization and weight reduction.

[0086] In addition, when a main roller (MR) is provided on the rotation bracket (211), the center of gravity (K) can be placed at a position adjacent to the main roller (MR), and the rotation bracket (211) can be easily rotated in another direction (b) using the load of the main roller (MR).

[0087] As illustrated in FIGS. 5 to 7, the rotation bracket (211) may be provided with an extension rib (211c) that is supported by making contact with the ground (g) in the second state (S2). As described above, in the second state (S2), a user's load is applied to the auxiliary part (200), and if the rotation bracket (211) is provided with an extension rib (211c), even when the user's load is applied, the extension rib (211c) is supported by making contact with the ground (g), thereby enabling stable load support.

[0088] At this time, as illustrated in FIGS. 5 to 7, the height adjustment member (210) may be provided with an auxiliary roller (SR) that is supported in contact with the ground (g) in the second state (S2). As described above, in the second state (S2), a user's load is applied to the auxiliary part (200), but if the height adjustment member (210) is provided with an auxiliary roller (SR), even if the user's load is applied, the auxiliary roller (SR) is supported in contact with the ground (g), thereby enabling stable load support and stable use of the auxiliary part (200) even in the second state (S2).

[0089] For example, the auxiliary roller (SR) may be arranged on an extension rib (211c), and further, the extension rib (211c) may be provided with an auxiliary shaft (SS) so that the auxiliary roller (SR) can rotate. The extension rib (211c) may include a pair of unit extension ribs that are arranged opposite to each other, and the auxiliary roller (SR) may be rotatably connected while being arranged between the pair of unit extension ribs. An auxiliary shaft (SS) may be connected between the pair of unit extension ribs so that the auxiliary roller (SR) can rotate.

[0090] However, the auxiliary roller (SR) is not necessarily limited to being placed on the rotation bracket (211), and may be placed at any other location as long as it can support the user's load while being supported in contact with the ground (g) in the second state (S2) while rotating together with the rotation bracket (211). As another example, the auxiliary roller (SR) may be placed on the cover (CV).

[0091] As shown in FIGS. 5 to 7, the height adjustment member (210) may be provided with an elastic member (220) that applies elastic force to the rotation bracket (211) to rotate in the other direction (b) when the use state is switched from the second state (S2) to the first state (S1).

[0092] As described above, in order to switch the use state from the second state (S2) to the first state (S1), the height of the auxiliary part (200) must rise, and this height increase of the auxiliary part (200) can be achieved through a separate rail structure while the auxiliary part (200) moves in the longitudinal direction (X), or can be achieved by the user directly lifting the auxiliary part (200), and when an elastic member (220) is provided, the height increase of the auxiliary part (200) can be easily achieved, and the transition from the second state (S2) to the first state (S1) can be smoothly achieved.

[0093] For example, the elastic member (220) may be a coil spring arranged to surround the rotary shaft (212b), but is not necessarily limited thereto, and any configuration may be used as long as it can provide elastic force to allow the rotary bracket (211) to rotate in the other direction (b) when the use state is switched from the second state (S2) to the first state (S1).

[0094] One side of the elastic member (220) is connected to the auxiliary part (200), and the other side of the elastic member (220) is connected to the rotation bracket (211), and the elastic member (220) can be elastically deformed in the process of the rotation bracket (211) rotating in one direction (a) when the use state is changed from the first state (S1) to the second state (S2).

[0095] As described above, the elastic member (220) provides elastic force so that the rotation bracket (211) rotates in the other direction (b) when the use state is switched from the second state (S2) to the first state (S1). To this end, the elastic member (220) is configured to be elastically deformed in the process of the rotation bracket (211) rotating in one direction (a) when the use state is switched from the first state (S1) to the second state (S2).
