Description

  The present invention relates to a support device for a thin display device in which extruded members (pulling members) having various cross-sectional shapes are connected via a connecting member to improve the installation property and handling property of the thin display device.

  With the increase in size of liquid crystal display devices and plasma display devices, thin display devices are widely used in general households. In these thin display devices, although the devices themselves are becoming larger and thinner, the stands and supporting legs that support them are not fully utilizing the installation properties of the thin display devices. For example, in a flat-screen television receiver having a large display screen of about 42 inches or 50 inches, it is common to support the lower part of the main body with a support leg and install the support leg on a TV stand (stand). It is. However, as the size of the thin television receiver increases, it is necessary to increase the bottom area of the support leg portion that supports the thin television receiver from the viewpoint of preventing the fall. In particular, in order to prevent overturning in the front-rear direction, it is necessary to increase the length of the support leg in the front-rear direction in proportion to the size of the display screen. Accordingly, the stand that supports the support leg from below also needs a large area in the front-rear direction in order to support the large support leg.

  For this reason, in a flat-screen television receiver, a TV stand with an installation surface that is not different from a conventional TV stand of a CRT television receiver in the installed state even if the folding angle and the depth of the main body can be reduced. Had to be adopted and did not benefit from the thinness.

  These flat-screen television receivers are the ones that can be most thinned when mounted on a wall, but because they are still heavy, they can only be installed on walls with a solid structure, Moreover, it cannot be said that it is an effective installation structure.

  On the other hand, some conventional television stands (stands) have a double arm provided on the television stand so that the television can be accommodated or swiveled in various directions. In addition, there are some furniture that has a double arm mechanism in the gap furniture so that the TV can be pulled out and rotated in various directions or stored in the gap furniture. Furthermore, a technique is also disclosed in which an arm mechanism is attached to a wall surface to support a television and turn or be stored in the wall surface.

  Further, conventional TV stands are mainly provided with a structure similar to that of furniture, or with a structure in which rod-like members are connected with bolts or the like. In the field of architecture, a technique is disclosed in which a structure with various specifications can be easily installed by removably connecting an extruded member (drawing member) such as an aluminum material with a connecting member.

  A thin display device having a large display screen typified by a thin television receiver tends to fall because the overall height is larger than that of the display screen. In order to prevent such a thin display device from falling, it is necessary to increase the size of the support leg and the stand that support the main body, and accordingly, the installation area of the support leg and the stand increases. On the other hand, in order to make use of the installation property of the thin display device, it is desirable to reduce the installation space, but there is a problem that reducing the installation space for the large screen is not sufficient for safety measures. In addition, a large display screen can take a posture with visibility when in use, and it is effective to be stored compactly when not in use. However, in the conventional example, regarding a small display device, there is a proposal to rotate or store it in various directions via an arm mechanism, but such an arm mechanism is heavy and large. There is a structural problem when applying to a thin display device.

  In particular, in the prior art provided with these movable TV holding mechanisms, the structure of the pivotable arm mechanism itself is disclosed, but the wall structure and the TV stand that support it are not structurally strong. Or, installation is not disclosed. Moreover, it has a special specification structure and cannot be said to be versatile.

The movable support 190 includes a movable support 190 and a mounting mechanism 200 that is pivotally attached to the movable support 190 and supports the television receiver 10.

  In this embodiment, a pair of struts that are held in a vertical posture in the longitudinal direction Y are connected by an arm portion 170, one strut is a fixed strut portion 110 via a base portion 150, and the other strut is a lower end portion. It is possible to turn around the fixed column 110 via the free wheel 193 provided on the vehicle. In addition, an attachment mechanism 200 that supports the television receiver 10 in a vertical posture is attached to the movable column 190 so as to be able to turn. In other words, this embodiment is provided with a movable shaft P2 that turns around the fixed shaft P1, and further has a structure in which the television receiver 10 in a vertical posture can be turned around the movable shaft P2. .

  That is, the fixed column 110 is formed of an extruded member having a circular cross-section that is held in a vertical posture in the longitudinal direction Y. Specifically, the fixed strut 110 includes a pair of main fixed struts 111A constituting the main body, an arm attachment 112A attached between the pair of main fixed struts 111A, and the arm attachment 112A. A rotation connecting portion 107 that rotatably connects the main fixed support 111A is configured.

  The main fixed support 111A and the arm attachment 112A have the same circular cross-sectional shape, as shown in the lower right outlet, and the cross-sectional shape is formed with a circular through hole 106 in the center. It is composed of an extruded member formed of aluminum or a light metal material in which a fitting slit 101 is formed along the longitudinal direction Y so as to form a positional relationship of 90 degrees around the periphery.

  The rotation connecting portion 107 has a structure including a pair of disks 107a and a rotating shaft rod 107b penetrating the pair of disks 107a. The arm attachment portion 112A is disposed between the pair of disks 107a, and the upper and lower ends thereof are arranged. It inserts into the through hole 106 of the upper and lower main fixed support 111A. Thereby, while connecting a pair of main fixed support | pillar part 111A and the arm attachment part 112 as one support | pillar, the arm attachment part 112 can be turned on the fixed axis P1 of this support | pillar.

  The base portion 150 includes a floor surface fixture 160 attached to the lower end portion of the main fixed column portion 111A and a ceiling surface fixture 161 attached to the upper end portion of the main fixed column portion 111A. The floor fixture 160 includes a non-slip member at the lower part of the thin disk part, and a projection (not shown) that is inserted into and attached to the lower end part of the main fixing column part 111A is provided on the upper surface thereof. In addition, the ceiling surface fixture 161 is provided with a projection (not shown) that is inserted into and attached to the upper end of the main fixed support 111A at the lower part of the thin disk part. The floor surface fixture 160 and the ceiling surface fixture 161 can adjust the length between the floor surface fixture 160 and the ceiling surface fixture 161 through a screw mechanism provided on the protrusion.

  According to the structure of the base portion 150 provided at both ends of the fixed support 110, an extruded member having a length close to the height of the ceiling surface is prepared for the fixed support 110, and through a screw mechanism, By extending so as to adjust the length between the floor surface fixture 160 and the ceiling surface fixture 161, the fixed column 110 can be fixed at an arbitrary position in the room. Here, if necessary, if the ceiling surface fixture 161 and the ceiling surface are screwed together, the fixed support 110A can be more reliably fixed.

  The arm portion 170 is composed of two rod-like extruded members having the same structure. Each of the pair of arm portions 170 includes an arm main body 171 and a pair of connecting devices 210 attached to both ends of the arm main body 171 in the longitudinal direction.

  The movable strut portion 190 rotatably connects the main movable strut 191 and the rotating strut 192 made of an extrusion-molded member having the same cross-sectional shape as the main fixed strut portion 110, and the main movable strut 191 and the rotating strut 192. The connecting shaft portion 108 and a universal wheel 193 attached to the lower end portion of the main movable column 191 are included. The main movable column 191 and the rotating column 192 have the same structure as the main fixed column 111 and the arm mounting unit 112 of the column 110, and the difference is the length in the longitudinal direction Y.

  Here, one end of the arm portion 170 is attached to the fitting slit 101 of the main movable column 191, and the connecting device 210 provided in the attachment mechanism unit 200 is attached to the fitting slit 101 of the rotating column 192. Thereby, the attachment mechanism part 200 can be swung with respect to the arm part 170 centering on the movable axis P2 which is an axial center of the main movable support column 191 and the rotation support column 192.

  The attachment mechanism part 200 includes an attachment main body part 250 provided with a coupling device 210 and a monitor holding part 251 attached to the attachment main body part 250 for supporting the television receiver 10.

  One of the major features of this embodiment is that the main structural member of the support device 100 is formed by an extruded member connected by a connecting device 210, and a thin display device (television receiver) is formed on the extruded member. The attachment mechanism 200 that supports the display screen 21 of the machine 10) in parallel is attached.

  That is, conventionally, in an exhibition facility or a simple building facility in an exhibition hall, a method of easily installing a three-dimensional structure by connecting rod-shaped extruded members with a connecting device is known (for example, Patent Documents). 3). These are formed by forming an extrusion molded member having a fitting slit 101 in the extrusion direction and a connecting device having a pair of fitting portions fitted into the fitting slit in accordance with a predetermined standard. They can be easily connected together and assembled into a predetermined structure, or can be easily disassembled.

  The inventors of the present invention have come up with the idea of applying the standard system adopted in this building facility to the television receiver system 1. That is, the present inventors have conceived a structure in which the extrusion molding member and the coupling device 210 form a skeleton of the support device 100. Extrusion molded members made of aluminum materials or light metals are widely used in various shapes. By adopting this standard method, various support devices 100 can be made inexpensive and light. In addition, it is possible to firmly support a large display device (television receiver 10) that is heavy while having a compact skeleton structure.

  However, in the standard system adopted in the building facility, since it is only applied to a simple structure such as a building or an exhibition facility, it is visually recognized like a thin display device (television receiver 10). A mechanism for supporting a heavy member while providing an outer shape of a large plate material having a large directivity is not prepared.

  Therefore, the present inventors have conceived an attachment mechanism portion 200 that supports the display screen 21 of the thin display device (television receiver 10) in parallel with the column portion 110 that is an extruded member. According to this attachment mechanism part 200, the thin display device (television receiver 10) can be compactly attached to the column part 110 while maintaining its visibility.

  Here, a schematic structure of the connecting device 210 having a known structure adopted in this embodiment is shown in the upper outlet of FIG. In other words, the coupling device 210 of this embodiment has a structure including a pair of fitting members 213 that are swingably supported via the fixing pins 212 in the coupling device main body 211. One end of the fitting member 213 is exposed from the coupling device main body 211, and the exposed tip end includes a protruding portion 214 that protrudes in a direction facing each other. The pair of fitting members 213 have their swinging range controlled by the screw member 215 so that the protruding portion 214 at the tip end of the fixing pin 212 is widened or narrowed in the protruding direction with the fixing pin 212 as the rotation axis. Is done. On the other hand, the fitting slit 101 is formed by a pair of slit end portions 102 being narrower than the slit interior 103.

  According to this structure, when the pair of protrusions 214 are inserted into the fitting slit 101 in a state where the pair of protrusions 214 are narrowed and the pair of protrusions 214 are expanded via the screw member 215, the pair of expanded protrusions 214 is expanded. And the slit interior 103 are fitted. Further, if the pair of projecting portions 214 are narrowed via the screw member 215, the pair of projecting portions 214 and the slit interior 103 can be disconnected. In this embodiment, a structure is adopted in which the coupling device main body 211 is inserted and attached to the end of the extruded member. Therefore, if the connecting device 210 provided at one end of the extruded member is fitted into the fitting slit 101 formed on the side surface of the extruded member, the two extruded members are firmly connected, and this connection is It can be released easily.

  In addition, one of the major features of this embodiment is that the television receiver 10 supported by the movable support column 190 is pivotally supported by the fixed support column 110 via the arm unit 170, so that a heavy object is obtained. The television receiver 10 is stably supported and the installation position can be changed.

  In other words, in this embodiment, the arm mounting portion 112 is rotatably attached to the main fixed support column portion 111 supported in a posture perpendicular to the base portion 150 in the same vertical posture (parallel posture). Thereby, in this embodiment, the fixed support | pillar part 110 provided with the rotation mechanism is comprised by one simple extrusion molding member. And since this simple fixed support | pillar part 110 is equipped with the structure where the movable support | pillar part 190 comprised with the same simple one extrusion molding member is connected via the arm part 170 of a horizontal attitude | position, it is movable. The part to do becomes a skeletal simple structure. For this reason, the movable support | pillar part 190 which supports the heavy television receiver 10 can be rotated without a sense of incongruity.

  In addition, one of the major features of this embodiment is that the attachment mechanism 200 is attached to the movable column 190 that is attached to be rotatable. That is, in this embodiment, a fixed shaft P1 and a movable shaft P2 that are two rotation shafts are provided at both ends of the arm portion 170, the movable shaft P2 is turned through the fixed shaft P1, and further, the movable shaft P2 is connected. Thus, since the thin television receiver can be turned in the horizontal direction, the viewing angle of the television receiver 10 can be freely changed.

  Also, one of the great features of this embodiment is that the main fixed support 110 is fixed to the floor and ceiling via the base 150 constituted by the floor fixture 160 and the ceiling fixture 161. It is in.

  In other words, in this embodiment, if there is a space where the fixed column part 110 has a ceiling surface, the fixed column part 110 can be freely installed between the ceiling surface and the floor surface. In addition, since the fixed support 110 can be installed in the form of a pole with a familiar extruded member such as a partition wall, its presence is easily harmonized with the furniture in the room.

  One of the major features of this embodiment is that the entire support device 100 has a simple and compact skeleton structure made of extruded members.

  That is, the conventional stand has a structure in which a plate material is attached to a strong skeleton, or a combination of four support columns and a glass plate material, or a structure including a support column and a large base plate that supports the support column. Is the mainstream. The support device 100 according to the present embodiment is significantly different from the structure of these conventional stands, and has a structure constituted by a combination of extruded members.

  Hereinafter, the television receiver system 1A according to the first embodiment will be described with reference to FIGS. 2 to 4 are explanatory views of the coupling device 210, FIGS. 5 and 6 are external views of the support device 100, FIG. 7 is an explanatory view of the mounting mechanism 200, and FIG. 9 is a use state diagram showing another installation state diagram, and FIG. 10 is a perspective view showing another application example of the attachment mechanism portion.

  First, the connecting device will be described in detail with reference to FIGS. As described above, a standard method for connecting extruded members using the connecting device 210 is widely known. This extrusion molding member uses a unit that is unified according to the same standard by including a fitting slit 101 in which the inner size of the slit interior 103 and the distance Q1 between the slit end portions 102 are formed with the same dimensions. The fitting slit 101 employs a known coupling device 210 including a pair of fitting members 213 that can be fitted into the fitting slit 101. Here, a known connecting device 210 according to one embodiment shown in FIGS. 1 and 2 and a connecting device 210a having the other structure shown in FIGS. 3 and 4 will be specifically described for reference. . In this embodiment, any of the coupling devices 210 and 210a can be used, and a coupling device having another structure that is widely used in the market can also be employed.

  Here, FIG. 2 is a cross-sectional view showing a connecting structure of the connecting device and the fitting slit, and FIG. 2A is a cross-sectional view showing a state in which the connecting device is inserted into the fitting slit, and FIG. It is sectional drawing which shows the state connected. 3 is a structural view of another connecting device, FIG. 3A is a sectional view, FIG. 3B is a plan view of one fitting member, and FIG. 3C is the other fitting member. FIG. FIG. 4 is a cross-sectional view showing a connecting structure of another connecting device and a fitting slit. FIG. 4A is a cross-sectional view showing a state in which the connecting device is inserted into the fitting slit, and FIG. It is sectional drawing which shows the state which carried out.

  First, with reference to FIG. 1 and FIG. 2, the connection structure of the connection apparatus 210 and the fitting slit 101 is demonstrated. 1 and 2, as described above, the coupling device 210 has a pair of fixed members so that the pair of fitting members 213 exposes the pair of protrusions 214 formed at the distal ends thereof from the coupling device main body 211. It is attached to the coupling device main body 211 via a pin 212. The pair of fitting members 213 are provided adjacent to each other so that their longitudinal directions are parallel to each other, and are attached to each other by a fixing pin 212 provided near the center so as to be swingable. A spring member 216 is provided on the end side facing the protrusion 214, and is always set to narrow the pair of protrusions 214 as shown in FIG.

  The pair of narrowed protrusions 214 is set to a size that passes through the slit between the slit end portions 102 of the fitting slit 101. Therefore, as shown in FIG. 2B from the state of FIG. 2A, the pair of protrusions 214 can be accommodated in the slit interior 103.

  One fitting member 213 has a screw member 215 attached between the fixing pin 212 and the protruding portion 214. The screw member 215 can be rotated by inserting a screwdriver or the like through an opening 217 provided in the coupling device main body 211. The tip of the screw member 215 is in contact with another fitting member 213, and by rotating the screw member 215, the tip of the screw member 215 protrudes, and the distance between the pair of projecting portions 214. Can be spread. That is, when the distance between the pair of projecting portions 214 is increased via the screw member 215, as shown in FIG. 2B, the pair of projecting portions 214 projecting in opposite directions and the slit projecting facing each other. The both ends 102 can be fitted.

  In this fitting state, if the screw member 215 is rotated in the reverse direction and loosened, the distance between the pair of protrusions 214 is reduced, so the state shown in FIG. 2B to the state shown in FIG. Can be.

  Next, FIGS. 3 and 4 show another connecting device 210a. The connecting device 210 in FIG. 2 employs a pair of fitting members 213 arranged in parallel, but the connecting device used in the present invention is not limited to this structure, and has the same effect. Anything that has 3 and 4 show other application examples.

  In FIG. 3, one fitting member 213a and the other fitting member 213b of the coupling device 210a intersect at the center in the longitudinal direction, and the coupling device main body 211 is rocked via the fixing pin 212 at the intersected position. It is mounted movably. One end of each of the fitting members 213a and 213b is provided with a protrusion 214 in an opposing direction and is exposed from the coupling device main body 211.

  One fitting member 213a has a cross opening 218 formed in the center, and the other end of the other fitting member 213b is formed so as to pass through the cross opening 218. Then, the other end of the other fitting member 213 b crosses through the cross opening 218 and is attached rotatably by the fixing pin 212.

  On the other hand, a screw member 215 is attached to the other fitting member 213b. As in the embodiment of FIG. 2, the screw member 215 can be rotated through an opening 217 formed in the coupling device main body 211, and its tip can be projected to one fitting member 213a.

  In FIG. 4A, even in the coupling device 210a, the pair of protrusions 214 can be inserted into the slit interior 103 through the slit both ends 102 with the pair of protrusions 214 narrowed. If the screw member 215 is rotated from the state shown in FIG. 4A and the tip end thereof is protruded, the other end sides of the fitting members 213a and 213b expand, and accordingly, the fixing member 212 is opposed to the fixing pin 212. The distance between the pair of protrusions 214 on the side can also be increased. That is, when the distance between the pair of projecting portions 214 is increased via the screw member 215, as shown in FIG. 4B, the pair of projecting portions 214 projecting in opposite directions and the slit projecting facing each other. The both ends 102 can be fitted.

  According to the connecting device 210a, the distance Q3 from the fixing pin 212 to the screw member 215 can be easily made longer than the distance Q2 from the fixing pin 212 to the protruding portion 214. Therefore, the screw member 215 is rotated by the lever principle. The force to be rotated can be rotated with a weak force.

  Thus, in this embodiment, a pair of protrusions 214 are inserted into the fitting slits 101 formed according to a unified standard, such as the connecting device 210 and the connecting device 210a described in FIG. 2 and FIG. Thus, any connecting device 210 having a structure for expanding this can be applied.

  That is, a television stand (stand) for installing a television receiver in a corner has been widely used. However, in the case of a cathode-ray tube type television receiver, the rear part is narrow, so the corner space of the corner could be used effectively. However, in the case of a thin television receiver, the corner space of the corner is It becomes dead space. In particular, when the display screen is enlarged, there is a problem that this dead space is increased. On the other hand, a conventional corner-type television stand or the like has a structure in which a television receiver is simply installed on the upper surface thereof, and thus cannot solve the above problem.

  However, in this embodiment, the column part 110 is installed at the corner portion of the corner, the arm part 170 can be turned with respect to the column part 110, and the television receiver 10 can be moved with respect to the tip of the arm part 170.

The television receiver 10 attached to the attachment mechanism part 200 can be set in a posture orthogonal to the arm part 170.

  As shown in FIG. 13, in the fixed support column 110 of this embodiment, the main fixed support column 111 and the arm mounting unit 112 are rotatably mounted on the same fixed axis P1. As described above, the main fixed support column 111 and the arm mounting portion 112 of this embodiment include the plurality of fitting slits 101 formed along the longitudinal direction Y, so that the fitting slit of the arm mounting portion 112 is provided. The arm portion 170 can be pivotably attached at any position of the length H3 of 101. Moreover, in this embodiment, since the fixed support | pillar part 110 and the movable support | pillar part 190 are formed with the same extrusion molding member, if the thing from which the main movable support | pillar part 191 of the movable support | pillar part 190 differs in length is prepared. The height of the television receiver 10 can be changed without changing other members.

  The attachment mechanism unit 200 includes an attachment main body 221 provided with the coupling device 210 and a monitor holding part 252 attached to the attachment main body 221. The mounting main body 221 has a flat appearance in the left-right direction having a depth dimension larger than the left-right dimension and a height dimension larger than the depth dimension. On the other hand, the monitor holding unit 252 has a structure in which the display screen 11 of the television receiver 10 is held in a vertical posture. Since this structure has been described with reference to FIG.

  Next, an installation method of the television receiver system 1 employing the “corner type” support device 100 will be described with reference to FIG. FIG. 14 is an installation state diagram of the television receiver system.

It is installed on the floor at an angle of 90 degrees. The arm portion 170 is pivotably attached to the fixed support 110 so as to extend toward the room. Therefore, this arm part 170 can turn in the range of 90 degrees.

  The television receiver 10 is attached to the tip of the arm unit 170 through the movable support column 190. Therefore, in the use state A in which the arm unit 170 is located at the center of the corner, it is possible to take a posture in which the television receiver 10 is directly opposed to the center of the room. If it is in the state of use state A, it can be installed like a conventional television receiver installed in a corner. In the state of use state A, the weight of the television receiver 10 is supported by the movable support column 190, and the posture thereof supports the fixed support column 110 connected through the pair of arm units 170. Since it is supported by the base part 150, it is not necessary to attach it to a wall surface or the like.

  On the other hand, in this embodiment, since the arm part 170 can be turned, the arm part 170 can be turned to one wall surface side. However, when the arm unit 170 is turned, one side of the television receiver 10 hits the wall surface. However, in this embodiment, the television receiver 10 can be rotated at the tip of the arm portion 170 via the movable support column 190, so that the television receiver 10 is mounted as in the use state B indicated by a broken line. The posture can be parallel to the wall. In this usage state B, even the television receiver 10 having a large display screen can be stored along the wall.

The L-shaped support member 253 has an L-shaped structure including a vertical member and a horizontal member formed at the tip thereof. One end of the rotating shaft portion 254 is attached to the lower surface of the horizontal member. By attaching the other end of the rotating shaft portion 254 projecting downward through the through hole 106 of the main movable support column 191 and fixing it with the fixing portion 255, the attachment mechanism portion 200A is rotatably attached to the tip of the arm portion 170. Can do.

  According to this structure, the 2nd member 192 of 1st Embodiment can be reduced in size, and a number of parts can also be reduced. Therefore, this structure can be easily adopted in the first embodiment and the second embodiment.

  Next, another application example of the support device will be described with reference to FIG. Here, FIG. 16 is an external view for explaining another application example of the support device.

  First, as described above, the support device according to this embodiment has a structure in which a plurality of extrusion-molded members can be simply connected and connected via the connecting device 210 and can be easily disassembled. Furthermore, other devices and reinforcing members can be attached using the fitting slits 101 formed in the extruded member.

  FIG. 16A shows an external structure of the support device 100B in which the strength of the base portion 150 is enhanced by attaching the bottom surface 156 to the base portion 150 of the support device 100 according to the second embodiment. In this embodiment, a quarter-circular bottom plate 156 that connects the pair of leg members 151 is provided so as to maintain the angle of the pair of leg members 151.

FIG. According to this structure, it is possible to reduce the opening of the pair of leg members 151 from a right angle, and therefore it is possible to reduce the fixed support 110 from falling forward due to the weight of the television receiver 10. .

  Further, the support device 100C shown in FIG. 16B has a structure in which the main movable support column 191 is eliminated and the weight of the television receiver 10 is supported only by the support of the arm unit 170. Since this structure is achieved by shortening the main movable support column 191 of the second embodiment, the detailed structure is omitted. However, since the television receiver 10 is supported only by the support of the arm portion 170, one of the pair of arm portions 170 is supported in a horizontal posture, and the other one is a tip portion in the horizontal posture and an arm mounting portion. It is preferable to have a structure that is connected obliquely so as to connect 112. Further, when the bottom plate 156 of FIG. 16A is also adopted in the base portion 150, the strength can be further increased.

  Further, the support device 100 </ b> D shown in FIG. 16C has a structure in which the free wheel 193 of the main movable column 191 can be moved on the upper surface of the bottom plate 156. That is, in this embodiment, the weight of the television receiver 10 is supported by the free wheel 193. Therefore, if the floor on which the free wheel 193 moves is a hard floor, the weight of the television receiver 10 can be received.

  Therefore, in the embodiment of FIG. 16C, a structure is adopted in which the radius of the bottom plate 156 is made smaller than that of the arm portion and the universal wheel 193 supported by the intermediate portion of the arm portion is provided. That is, in the support device 100D according to the embodiment of FIG. 16C, the arm portion 170D includes a main arm portion 175 and a sub arm portion 176 that is shorter than the main arm portion. One end of the main arm portion 175 is attached to the arm attachment portion 112, and the other end is attached to the fitting slit 101 of the rotary column 192 described in the second embodiment. Also, a leg support 177 made of an extrusion molding member is prepared, and a free wheel 193 is attached to one end in the longitudinal direction, and the other end is attached to the fitting slit 101 on the bottom surface of the main arm 175. Then, the side surface (fitting slit 101) of the leg support column 177 and the arm attachment portion 112 are connected by the sub arm portion 176. In addition, the rotation shaft portion 254 of the attachment mechanism portion 200A is attached to the rotary column 192.

  According to the support device 100D, the same effects as those of the second embodiment can be obtained, and the free wheel 193 to which a load is applied can be received by the bottom plate 156. Further, since the leg column 177 supporting the universal wheel 193 is disposed so as to be recessed and movable, the presence of the leg column 177 can be reduced.
