In addition, the lifting rail 44 can extend upward through the mounting portion bracket 46 when extending.

[0288] Figure 14 It is a cross-sectional perspective view of a board mounted on the drawer body.

[0289] As shown in the figure, in the state where the lifting shaft 43 and the lifting rail 44 are installed, the drawer body can be formed by installing an outer panel 391, an inner panel 392, and an inner panel 395 on the drawer body 38 The appearance of 38 inside and outside.

[0290] In detail, the exterior of the left and right sides that can be exposed when the drawer door 30 is drawn out can be completely shielded by the outer panel 391. That is, the pull-out/introduction rail 33, which is at least a part of the drawer side device 42 arranged on the side surface of the drawer body 38, and the drawer side shaft 47, etc., are arranged on the outer side surface of the drawer body 38 All the components are shielded by the outer panel 391. The outer panel 391 is configured to have a metallic texture, so as to visually provide a neater and high-end appearance.

[0291] In addition, the inner panel 392 and the inner panel 395 form a space inside the drawer 32 that can be seen when the drawer door 30 is drawn out, thereby providing the drawer 32 with a sense of integration. Appearance.

[0292] Through the installation of the plurality of plates 391, 392, 395, the appearance and inner side of the drawer portion 32 will have a metallic texture visually. Although the lower surface, rear surface and front surface of the drawer portion 32 that are not exposed to the outside, and the front surface combined with the door portion 31, there are no additional panels for exterior decoration, but the part exposed to the outside is actually The upper part is covered by the plates 391, 392, and 395.

[0293] In particular, it may be provided that the mounting portion 383 can be exposed through the side opening 394 when the inner side plate 392 is mounted. That is, in the state where the inner side plate 392 is installed, the lifting shaft 43 and the lifting rail 44 inside the mounting portion 383 can be exposed, and the remaining part can be shielded by the inner side plate 392. After that, the supporting member 35 and the connecting bracket 45 can be combined with or separated from the shaft holder 48 and the lifting rail 44 through the exposed side opening 394.

[0294] In addition, the upper end of the inner plate 392 can be formed to be bent outward, and the bent upper end can cover the upper ends of the two sides of the drawer body 38 and the mounting bracket 46 and interact with the upper end of the outer plate 391. Connect to form an appearance.

[0295] The lifting plate 351 that substantially supports food or containers in the supporting member 35 may be located on the bottom surface inside the drawer body 38. In addition, the lower ends of the mounting portion 383 and the side opening 394 are located above the lifting plate 351, thereby making it easier to install and maintain the lifting shaft 43 and the lifting rail 44. In addition, the upper ends of the mounting portion 383 and the side opening 394 extend to the upper end of the side of the drawer body 38, so that the stroke of the supporting member 35 can be used to the maximum.

[0296] Figure 15 It is a cross-sectional perspective view of a connecting bracket installed on the drawer body.

[0297] As shown in the figure, the lower end of the connecting bracket 45 is fixed to the supporting member 35, and the outer side surface can be combined with the shaft holder 48 and the supporting member 35. Therefore, the lifting plate 351 or the lifting frame 352 can be connected to the shaft holder 48 and the connecting bracket 45 by the connecting bracket 45. At this time, on the basis of the plate-shaped connecting bracket 45, the supporting member 35 and the connecting bracket 45, the shaft holder 48, the lifting rail 44 and the connecting bracket 45 are respectively located The opposite sides are combined.

[0298] When the supporting member 35, the shaft holder 48, and the lifting rail 44 are combined with the connecting bracket 45, if the lifting shaft 43 rotates, the shaft holder 48 can be connected to the connecting bracket 45 The carriage 45 moves in the up and down direction together. In addition, the connecting bracket 45 can be guided in the vertical direction by the elevating rail 44 arranged in the center, and the supporting member 35 can be moved up and down in a stable state without tilting.

[0299] At this time, if the shaft holder 48 moves upward along with the lift shaft 43, as the lift rail 44 extends, the connecting bracket 45 can also move upward together and can be lifted upward. The supporting member 35. Conversely, if the shaft holder 48 moves downward along with the lift shaft 43, the lift rail 44 shrinks, the connecting bracket 45 moves downward together with the lift rail 44, and the support member 35 Move toward the bottom surface inside the drawer body 38.

[0300] Figure 16 It is a partial perspective view showing a state where a side cover is attached to the drawer body.

[0301] in Figure 15 In the state shown, the connecting bracket 45 can be combined with the side cover 353. The side cover 353 may be formed to not only cover the connecting bracket 45 but also to cover both the mounting portion 383 and the side opening 394.

[0302] The side cover 353 may also be combined with the side end of the lifting frame 352 or the lifting plate 351. Therefore, the support member 35 can be moved in the vertical direction together when the support member 35 is lifted and the lift rail 44 is drawn/introduced, and the lift shaft 43, the lift rail 44, and the connecting bracket that constitute the drawer side device 42 can be prevented. The frame 45 is exposed.

[0303] In addition, an upper end shielding portion 353d formed by bending outward is formed at the upper end of the lifting side cover 353. The upper end shielding portion 353d can not only shield the inner side surface of the drawer portion 32, but also shield the drawer portion. A part of the upper end of 32 can also shield the upper end of the mounting bracket 46 or the lifting rail 44 that can be exposed to the upper end from above.

[0304] In addition, the side cover 353 is formed to cover the connecting bracket 45 to prevent the connecting bracket 45 from being exposed. Also, the side cover 353 may be formed of the same material as the inner side plate 392.

[0305] That is, in the state where the side cover 353 is attached, not only the connecting bracket 45 is not exposed, but the lifting shaft and the lifting rails that are shielded by the connecting bracket 45 are also not exposed. Therefore, the inner side surface of the drawer portion 32 may be formed by the side cover 353 and the inner side plate 392.

[0306] The side cover 353 can be formed by injection molding of plastic material as required, or a cover plate 354 formed of a metal material similar to the inner plate 392 or a cover plate 354 formed of a metal material on the side cover 353 can be attached to the outer side of the side cover 353. The outer surface is coated with a metallic texture.

[0307] Since the side cover 353 is connected to the connecting bracket 45, it can be raised and lowered together when the support member 35 is raised and lowered. Even when the support member 35 is raised and lowered, the connecting bracket 45 The concealed components will not be exposed to the outside, and the unity of the appearance is still maintained.

[0308] Hereinafter, with reference to the drawings, the drawing/introducing and lifting state of the drawer door 3 of the refrigerator 1 of the embodiment of the present invention having the above-mentioned structure will be described in detail.

[0309] Figure 17 It is a perspective view of a state where the drawer door is closed.

[0310] As shown in the figure, the revolving door 20 and the drawer door 30 of the refrigerator 1 are kept closed when food is stored. In this state, the user can store food by drawing out/introducing the drawer door 30.

[0311] A plurality of the drawer doors 30 can be arranged above and below, and can be drawn out and opened by the user's operation. At this time, the user's operation may be to touch the operating part 301 provided on the front surface of the revolving door 20 or the drawer door 30, or it may be an input based on the opening operation of the operating device 302 provided at the lower end of the drawer door 30 . Furthermore, it may be configured such that the operating portion 301 and the operating device 302 individually control the drawing/introducing of the drawer door 30 and the lifting of the supporting member 35 respectively. Of course, the user can also grab the handle of the drawer door 30 to open it.

[0312] In addition, although the case where the drawer door 30 located at the bottom of the drawer doors 30 arranged on the upper and lower sides is opened and raised and lowered is described as an example, the upper and lower drawer doors 30 can be performed in the same manner. Lead out / lead in and lift.

[0313] Figure 18 It is a perspective view of a state where the drawer door is completely opened. Figure 19 Is with Figure 18 A cross-sectional view of the drawer door in the same state.

[0314] As shown in the figure, the drawer door 30 is drawn forward as the user performs the drawing operation of the drawer door 30. The drawer door 30 may be drawn out as the lead-in/out rail 33 extends.

[0315] In addition, it can be configured that the drawer door 30 is drawn out/introduced by the drive of the extracting/introducing motor 14 instead of being opened by the user directly pulling it. The extraction/introduction rack 34 provided on the bottom surface of the drawer door 30 can be combined with a pinion 141 that is provided on the box body 10 and rotates when the extraction/introduction motor 14 is driven, so that the drawer door 30 can follow It is led out/introduced by the driving of the extraction/introduction motor 14.

[0316] With regard to the lead-in distance of the drawer door 30, it can be drawn at least as far as the front space S1 inside the drawer portion 32 is completely exposed to the outside. Therefore, in this state, it is possible to prevent the support member 35 from being disturbed by the doors 20 and 30 or the box 10 arranged above.

[0317] At this time, the lead-in/out distance of the drawer door 30 can be realized by the lead-in/out detection device 15 arranged on the box body 10 and/or the drawer door 30. The extraction/introduction detection device 15 may be constituted by a detection sensor for detecting a magnet 389, so as to be able to detect the state that the drawer door 30 is fully drawn out or fully closed.

[0318] For example, as shown in the figure, a magnet 389 may be provided at the bottom of the drawer portion 32 and a detection sensor may be provided on the box body 10. The extraction/introduction detection device 15 may be arranged at a position corresponding to the position of the magnet 389 in a state where the drawer door 30 is closed and the position of the magnet 389 in a state where the drawer door 30 is fully drawn out. In this way, the withdrawal/introduction state of the drawer door 30 can be judged by the withdrawal/introduction detection device 15.

[0319] In addition, it is also possible to detect the withdrawal/introduction of the drawer door 30 by setting switches on the fully drawn-in position and the fully drawn-out position of the drawer door 30 as required, and also calculate the lead-in/out motor 14 The number of revolutions or a sensor for measuring the distance between the back of the door portion 31 and the front end of the box body 10 detects the lead-in/out of the drawer door 30.

[0320] In a state where the drawer door 30 is completely drawn out, the supporting member 35 can be raised by driving the lifting motor 411. The supporting member 35 can be operated while ensuring that the food or container 36 placed on the supporting member 35 can be lifted and lowered safely after the drawer door 30 is fully drawn out.

[0321] That is, when the drawer door 30 is drawn out and the front space is completely exposed to the outside, the supporting member 35 rises, thereby preventing the container 36 or the stored food placed on the supporting member 35 from being blocked by other doors. 20, 30 or box 10 interference.

[0322] The supporting member 35 may start to rise after confirming that the drawer door 30 is completely drawn out. In addition, it may also be provided that the support member 35 starts to rise after a set time has elapsed after confirming the drawing of the drawer door 30 to ensure the safety of the user and prevent damage to the stored food.

[0323] Of course, after the drawer door 30 is drawn out, the user can also directly input the rising of the supporting member 35 by operating the operating portion 301. That is, the user may operate the operation part 301 for drawing out the drawer door 30, or may operate the operation part 301 again for the raising and lowering of the support member 35. In addition, the user can manually introduce/extract the drawer door 30, and after pulling out the drawer door 30, by operating the operating portion 301 to lift the supporting member 35.

[0324] Picture 20 It is a perspective view of a state where the drawer door is fully raised. Figure 21 Is with Picture 20 A cross-sectional view of the drawer door in the same state.

[0325] With Figure 18 with Figure 19 In the same state, that is, in a state where the drawer door 30 is drawn out, the support member 35 can be raised and lowered. The supporting member 35 can be raised and lowered by the action of the lifting motor 411, and the supporting member 35 can be received in a state where the door side device of the door portion 31 and the drawer side device 42 of the drawer portion 32 are combined with each other. Power and lift.

[0326] In more detail, if the lifting motor 411 operates, the door shafts 413 on both sides connected to the lifting motor 411 rotate, and then the first gear 414 and the second gear 414 connected to the door shaft 413 are rotated. The gear 415 rotates.

[0327] The rotation force of the door side device 41 can be transmitted to the drawer side device 42 via the door connection member 416 and the drawer connection member 471 connected to each other. Therefore, the rotational force transmitted from the door side device 41 causes the drawer side shaft 47 and the drawer side gear 472 at the ends of the drawer side shaft 47 to rotate.

[0328] The drawer-side gear 472 and the shaft gear 434 may transmit rotational force in a state of being connected to each other, and the rotational force of the drawer-side shaft 47 will cause the lifting shaft 43 to rotate. By the rotation of the lift shaft 43, the shaft holder 48 moves upward along the lift shaft 43.

[0329] At this time, the shaft holder 48 moves upward together with the connection bracket 45 in a state coupled to the connection bracket 45, and the support member 35 coupled to the connection bracket 45 also moves upward together. At this time, the lifting rail 44 at the center of the connecting bracket 45 extends upward and guides the lifting of the supporting member 35 so that it does not incline and rises stably.

[0330] In addition, the side covers 353 on both sides of the supporting member 35 shield the connecting bracket 45, the mounting portion 383, and the internal components of the mounting portion 383 to prevent these components from being exposed, and also prevent the food stuff inside. In or in.

[0331] In addition, the supporting member 35 is raised at a sufficient height to allow easy access to the food or container placed on the supporting member 35, thereby enabling the user to easily lift the food or container.

[0332] The rising height of the supporting member 35 can reach the point where the shaft holder 48 is located at the upper end of the lifting shaft 43. Moreover, when the lifting of the supporting member 35 ends, the lifting motor 411 stops driving.

[0333] If the raising end signal of the supporting member 35 is input, the driving of the lifting motor 411 is stopped. For this purpose, a height detecting device 16 capable of detecting the position of the supporting member 35 may be provided. The height detecting device 16 is provided on the door portion 31 and can be provided at a height corresponding to the maximum rising position of the support member 35 and the lowest falling position of the support member 35.

[0334] The height detection device 16 may be constituted by a detection sensor for detecting the magnet 355, and it can be determined whether the raising of the supporting member 35 is finished by detecting the magnet 355 provided on the supporting member 35. In addition, the height detecting device 16 may be configured as a switch structure, and the switch may be turned on when the support member 35 is raised to the highest position. In addition, the height detection device 16 may also be installed on the lifting rail 44 or the lifting shaft 43 and detect the highest position where the support member 35 rises. In addition, it may be determined whether the rise of the supporting member 35 is the highest based on the fluctuation of the load applied to the lifting motor 411.

[0335] In addition, when the supporting member 35 is raised to the highest position, the lifting motor 411 stops. In this state, although the support member 35 is located inside the drawer portion 32, the food or container 36 placed on the support member 35 may be located higher than the upper side of the opening of the drawer portion 32 Location, users can easily access. In particular, there is no need to excessively bend over in order to lift the container 36, so safe and convenient operation can be realized.

[0336] After the user's food storage operation is completed, the user can lower the support member 35 by operating the operating portion 301. The lowering of the supporting member 35 can be realized by the reverse rotation of the lifting motor 411, and can be completed slowly by the process opposite to the process described above.

[0337] And, if the support member 35 is finished descending, it becomes as Figure 18 or Figure 19 In the state, the end of the lowering of the supporting member 35 can be completed by the height detecting device 16. In order to detect the magnet provided on the supporting member 35 when the supporting member 35 is at the lowest position, the height detecting device 16 may be further provided at the corresponding position. Therefore, if the end of the lowering of the supporting member 35 is detected, the lifting motor 411 will stop.

[0338] Also, the drawer door 30 may be introduced after the lifting motor 411 stops. At this time, the drawer door 30 can be closed by a user's operation, or can be closed by the drive of the lead-in/out motor 14. If the drawer door 30 is completely closed, it can become as Figure 17 The same state.

[0339] In addition, the present invention may have various other embodiments in addition to the above-mentioned embodiments.

Therefore, through the shaft insertion port 552, not only the installation and separation of the drawer-side mounting portion 383 can be confirmed, but also the combined state of the drawer-side gear 523 and the shaft gear 572 can be confirmed, and the housing can be prevented. The body 55 interferes with the actions of the drawer side gear 523 and the shaft gear 572.

[0393] The drawer side shaft 52 may be composed of a drawer shaft 521 having a predetermined length, a drawer connecting member 522 provided at the front end of the drawer shaft 521, and a drawer side gear 523 provided at the rear end of the drawer shaft 521. The drawer connecting member 522 may be combined with the door connecting member 416 when the door portion 31 and the drawer portion 32 are combined, and the drawer side gear 523 may be combined with the shaft gear 572. In addition, the drawer side shaft 52 may be fixedly mounted on the drawer body 38 through a pair of shaft fixing members 524.

[0394] The connecting bracket 54 may be composed of a rail coupling portion 541 combined with the lifting device 51 and a supporting member coupling portion 542 combined with the supporting member 35.

[0395] The rail coupling portion 541 forms an upper portion of the connecting bracket 54 and can be coupled with the block holder 56 exposed to the outside of the lifting device 51. The block holder 56 may be firmly coupled with the rail coupling portion 541 by a coupling member like a screw.

[0396] The supporting member coupling portion 542 is formed at the lower end of the rail coupling portion 541 and can be coupled with both ends of the supporting member 35. The supporting member coupling portion 542 is formed to have a width greater than the lateral width of the rail coupling portion 541 so as to stably support both ends of the supporting member 35.

[0397] The supporting member coupling portion 542 can be bent multiple times to form a coupling groove 542a opening upward, and both ends of the supporting member 35 can be installed in the coupling groove 542a. In detail, the lifting frame 352 can be inserted into the coupling groove 542a, and inserted into the connecting bracket mounting portion 351b through the rail coupling portion 541, so that the supporting member 35 and the connecting bracket 54 are coupled To not swim.

[0398] The supporting member 35 is a structure that is installed from above the coupling groove 542a to the bottom, so that it can be mounted on the connecting bracket 54 without a coupling member like screws, and can be installed inside the drawer body 38. Has a strong and stable bonding structure. Therefore, the lifting device 51 can be easily separated when the maintenance of the lifting device 51 is required, and there is an advantage that the supporting member 35 can be easily separated when the lifting function is not used.

[0399] Hereinafter, the structure of the lifting device will be described in detail with reference to the drawings.

[0400] Figure 29 It is an exploded perspective view of the elevating device, which is a main component of the drawer side device, viewed from one direction. Figure 30 It is an exploded perspective view of the structure of the lifting device viewed from another direction. Figure 31 It is a cross-sectional perspective view showing a cross section of the lifting device.

[0401] As shown in the figure, the lifting device 51 may be formed by the housing 55. In addition, a space for accommodating the lifting shaft 57 and the block holder 56 is formed inside the housing 55, and the inner side of the opening can be shielded by the rail cover 59.

[0402] The housing 55 may include the central part 553 and side parts 554. The central portion 553 may be formed at a position corresponding to the lifting shaft 57, and at least a part of the lifting shaft 57 can be accommodated in the central portion 553. And, it can be installed in the first installation part 383.

[0403] The side portions 554 are formed to extend in a stepped manner on both sides of the central portion 553 and are formed to be mountable to the second mounting portion 383. The side portions 554 can be bent vertically to form the two side surfaces of the casing 55 after the two side ends of the central portion 553 extend to both sides, and the two side ends of the casing 55 face again The inside is bent.

[0404] Therefore, by the side portion 554, a space for accommodating the lifting shaft 57 and the block holder 56 can be formed inside the housing 55. In addition, the two ends of the side portion 554 are bent in opposite directions to form a housing opening 551 therebetween. The housing opening 551 is formed to have a lateral width greater than the diameter of the lifting shaft 57, thereby facilitating the installation of the lifting shaft 57, and is formed to be smaller than the width of the block holder 56, thereby preventing The block holder 56 is disengaged through the housing opening 551. The housing opening 551 can be shielded by the track cover 59.

[0405] The lifting shaft 57 can be accommodated inside the casing 55 and can be located at the central part 553. In addition, a thread 571 is formed on the outer peripheral surface of the lifting shaft 57 so that the lifting block 567 can move in the vertical direction along with the lifting shaft 57 when the lifting shaft 57 rotates.

[0406] The lifting block 567 may include: a block 567a formed with a block through hole 567b for penetrating the lifting shaft 57; and a block coupling portion 567d extending from the block 567a to both sides. The block 567a is formed in a cylindrical shape, and the block through opening 567b can be formed through the center of the block 567a in the vertical direction. A thread corresponding to the thread 571 is formed on the inner peripheral surface of the block through hole 567b. Therefore, when the lifting shaft 57 rotates, the lifting block 567 can move in the up and down direction as the thread 571 moves. mobile.

[0407] In addition, a block fastening opening 567c may be formed on the upper surface of the lifting block 567. The block fastening opening 567c is formed on both sides with the block penetration opening 567b as the center, and is formed to be able to fasten a screw 567f so that the lifting block 567 can be combined with the block holder 56 and moved together.

[0408] In addition, the block coupling portion 567d extends from the center of the block 567a to both sides, and a block groove 567e extending in the vertical direction may be formed at the extended end of the block coupling portion 567d. The block grooves 567e on the left and right sides may be combined with the block holder 56 so that the lifting block 567 and the block holder 56 are further firmly combined.

[0409] The block holder 56 can be raised and lowered together inside the housing 55 by being coupled with the elevating block 567, and has a part that is exposed to the outside of the housing 55 and can be coupled to the connecting bracket 54 structure.

[0410] In detail, the block holder 56 may be composed of an inner portion 56a housed in the housing 55 and an outer portion 56b exposed to the outside of the housing 55. In addition, the block holder 56 is hollow inside, so that a space 560 can be formed. Especially in the lower part of the block holder 56, more specifically, at the lower part of the inner portion 56a, a space 560 may be formed for accommodating the lifting block. 567's block storage 564. The block accommodating part 564 is opened backward and downward, and may be formed to communicate with the hollow. Therefore, the lifting block 567 can be inserted and installed from the lower direction of the inner portion 56 a upward, and is located inside the block accommodating portion 564.

[0411] Above the block accommodating portion 564, that is, at the center of the inner portion 56a, a shaft penetration portion 562 penetrating in the vertical direction may be formed. The lifting shaft 57 passes through the inner side of the shaft penetration portion 562. At this time, the thread 571 of the lifting shaft 57 will not be combined with the inner peripheral surface of the shaft penetration portion 562, and the lifting shaft 57 will not The inner surface of the shaft penetration portion 562 is in contact with each other. In addition, in a state where the lifting block 567 is located inside the block accommodating portion 564, the centers of the shaft penetration portion 562 and the block penetration opening 567b are located on the same extension line.

[0412] On both sides of the outer side surface of the shaft through portion 562, a holder fastening portion 565 for fastening a block groove 567e may be formed, and the block groove 567e is used to couple the lifting block 567 and the block holder 56. The holder fastening portion 565 is located at a position corresponding to the block fastening opening 567c, and when the lifting block 567 and the block holder 56 are combined, they can be arranged in the vertical direction with each other. Therefore, the block groove 567e can be fastened to the holder fastening portion 565 by penetrating the block fastening opening 567c, and the lifting block 567 and the block holder 56 can be fixed integrally.

[0413] On both sides of the shaft penetration portion 562, side extension portions 563 extending laterally may be formed. The side extension portion 563 extends laterally from the shaft penetration portion 562 and can extend along the side portion 554 to two side surfaces of the housing 55. In addition, it can be bent along the shape of the inner surface of the side portion 554 and extend to the housing opening 551. That is, the side extension portion 563 can be bent and formed to correspond to the shape of the inner side surface of the side portion 554.

[0414] In addition, a bearing mounting portion 383 may be formed on the side extension portion 563 facing the side surface of the housing 55. The bearing mounting portion 383 may be formed to be recessed inward, and the plurality of bearings 568b may be continuously arranged in the vertical direction. A plurality of the bearings 568b can be installed in a rotatable state through the positioner 568a, and the positioner 568a can be fixed on the bearing installation portion 383. The bearing 568b and the positioner 568a may be referred to as rolling members. The rolling member is not limited to the structure of the bearing 568b and the positioner 568a. Other structures that can roll between the block holder 56 and the housing opening 551 are can.

[0415] A plurality of the bearings 568b are sandwiched between the inner side surface of the housing 55 and the side extension portion 563, and are respectively connected to the housing 55 and the side extension portion 563 and capable of rolling. In addition, the bearing 568b may be arranged in the bearing mounting portion 383 on both sides. Therefore, the block holder 56 can be smoothly raised and lowered on the inside of the housing 55, and especially maintains the state of contact with the inner surface of the housing 55 during the lifting process, so that it does not swim and can be stable and smooth. Land lift. In addition, a recess is formed on the inner surface of the side portion 554 that is in contact with the bearing 568b at a position facing the bearing mounting portion 383, so that relatively stable rolling of the bearing 568b can be achieved.

[0416] In addition, the outer portion 56b may extend to be able to pass through the housing opening 551 on both sides of the side extension portion 563. In addition, it is formed protrudingly through the housing opening 551 so that the outer portion 56 b is combined with the connecting bracket 54.

[0417] The outer portion 56 b forms a bracket mounting portion 561 for coupling with the connecting bracket 54, and the bracket mounting portion 561 is located outside the housing opening 551. Therefore, even if it is lifted and lowered in a coupled state with the connecting bracket 54, it is possible to prevent the connecting bracket 54 from interfering with the housing 55 or the rail cover 59.

[0418] Both ends of the bracket installation portion 561 can extend vertically and are connected to the side extension portion 563 respectively. At this time, the thickness of the bracket mounting portion 561 is at least thinner than the width of the guide slit 511 so that the block holder 56 can move along the guide slit 511.

[0419] Inside the block holder 56, that is, inside the inner portion 56 a and the outer portion 56 b, a hollow space 560 is formed, and is formed so that the rail cover 59 can be accommodated inside the space 560. In addition, the block holder 56 can move up and down along the guide gap 511 formed by the rail cover 59 and the housing 55.

[0420] In addition, the bracket mounting portion 561 may extend downward from the outside of the housing 55. In a state where the block holder 56 is located at the lowest position, the bracket mounting portion 561 may be located at a lower position than the housing 55. At this time, the housing 55 is located above the lead-in/out rail 33, so that it can be installed so that there is no interference in the area under the lead-in/out rail 33 and the drawer flange 380. In addition, the bracket mounting portion 561 extends downward so as to pass through the lead-out/introduction rail 33, and is connected to the supporting member 35 located on the inner bottom surface of the drawer body 38 or to the supporting member 35. The connecting bracket 54 is combined.

[0421] In addition, the block holder 56 has a structure that extends laterally so that the side extension portion 563 can be accommodated inside the side portion 554, and also has a structure such that the outer portion 56b can pass through the housing The protruding or bending structure of the opening 551 will restrict the movement of the block holder 56 in the forward and backward directions or the left and right directions as the whole of the housing 55 moves up and down. Therefore, when the support member 35 is raised and lowered, even if a load is added to the block holder 56, the block holder 56 does not become detached, and can be stably moved up and down.

[0422] A block restriction protrusion 569 may be formed on both sides of the side extension portion 563 adjacent to the shaft penetration portion 562. The block restricting protrusion 569 may be formed on the side extension portion 563 long in the up and down direction, and may extend from the lower end to the upper end of the inner portion 56a. In addition, the block restricting protrusion 569 can be combined with the block grooves 567e on both sides of the lifting block 567. The block restricting protrusion 569 and the block groove 567e can be coupled by being inserted into each other when the elevating block 567 is moved from the lower direction of the block holder 56 upward and coupled, and as the elevating block 567 moves upward Movement will form an overall union. The lifting block 567 and the block holder 56 can be firmly coupled to each other by the combination of the block restricting protrusion 569 and the block groove 567e, and have a structure capable of lifting together. The block holder 56 has a structure that is combined with the lifting block 567 in the up and down direction, and thus can have a structure that can be easily formed by processing like extrusion as a whole.

[0423] That is, since the screw needs to be formed in a manner that moves along with the lifting shaft 57, the structure of the screw is complicated, and the lifting block 567 that requires abrasion resistance and lubrication performance can be molded by engineering plastic injection molding. In addition, when the supporting member 35 moves, the load is substantially increased, so that the lifting block 567 that requires high strength can be formed to have a structure that can be formed from a metal material by extrusion. The lifting block 567 and the block holder 56 formed of different materials in a manner matching each structure and environment can be integrally lifted and lowered inside the housing 55 by being combined with each other.

[0424] A lower spacer 586 for supporting the lifting shaft 57 in a rotatable manner may be provided under the lifting shaft 57. The lower protrusion 437 protruding at the lower end of the lifting shaft 57 can be inserted into the lower spacer 586. The lower spacer 586 may be formed into a bearing-like structure, so the lifting shaft 57 can rotate while being supported by the lower spacer 586.

[0425] The lower spacer 586 can be fixed and installed on the lower cap 585. The lower cap 585 is installed to cover the lower side of the opening of the casing 55 and forms the lower surface of the lifting device 51. A lower spacer mounting part 585a capable of inserting and installing the lower spacer 586 may be formed in the center of the lower cap 585. In addition, lower cap coupling portions 585c may be formed on both sides of the lower spacer mounting portion 585a.
