  The present invention relates to an elevating shelf including a box-shaped cabinet whose rear surface is fixedly installed on a wall surface and at least opened downward, and a hanging shelf body attached to the cabinet so as to move up and down linearly.

  2. Description of the Related Art Conventionally, as a kind of a hanging shelf installed above a kitchen, a so-called lifting shelf in which a hanging shelf body is raised and lowered is provided. There are two types of lifting shelves: manual type and electric type. As a manual type, for example, Patent Literature 1 proposes an elevating shelf including a hanging shelf body that moves up and down in a straight line.

Japanese Patent No. 4801454

  In the lifting shelf, the hanging shelf body is housed in a cabinet installed on the wall surface when not in use, and is pulled out of the cabinet when in use. That is, the use position and the storage position are determined such that the hanging shelf body is positioned above (inside the cabinet) when stored (when not in use) and positioned below (outside the cabinet) when used. When the user's hand moves away from the handle arm when the suspension rack body is in the midway position, the suspension rack body is usually lowered to the use position by the weight of the suspension rack body. In addition, the suspension rack body is often provided with a spring that pulls upward to reduce the weight of the stored items. However, when the stored items are small, the suspension rack body may rise to the storage position.

  However, there is a request to keep the hanging shelf body in the midway position. For example, it is considered that the user-friendliness is improved because the working space can be secured if the hanging shelf body is slightly raised from the lower end when it is accommodated in the hanging shelf body one after another while washing dishes and the like.

  Further, when the user releases his / her hand, if the hanging shelf body is lowered by gravity or lifted by a spring, there is a possibility that momentum may be applied depending on the weight of the contents. Then, there is a possibility that an impact sound may be generated at the lower end or upper end of the movement of the hanging shelf body, or the contents may fall down.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a lifting shelf that can stop the suspension shelf main body at a midway position, prevent a sudden rise or a sudden drop of the suspension shelf main body, and enhance user-friendliness. .

  In order to solve the above problems, a typical structure of a lifting shelf according to the present invention includes a box-shaped cabinet whose back is fixedly installed on a wall surface and at least opened downward, and a tip attached to the cabinet bulges toward the front. Left and right arm members that can swing up and down along an arcuate locus, a hanging shelf body attached to the cabinet to move up and down in a straight line, and an arm that is slidable in the longitudinal direction on the left and right side plates of the hanging shelf body A swing column connected to the member, and a lock mechanism that restricts the vertical movement of the hanging shelf body by restricting the movement of the swing column at a midway position.

  In the above configuration, when the swinging column slides back and forth, the left and right arm members rotate along an arcuate locus along with the movement of the swinging column, and the suspension rack body moves up and down in conjunction with the swinging column. To do. At this time, by providing a lock mechanism that restricts the movement of the swinging column in the front-rear direction at a midway position, the vertical movement of the hanging rack body can be restricted at a position other than the use position and the storage position. . Therefore, the suspension rack body can be stopped at a midway position, and sudden rise and sudden drop of the suspension rack body can be suitably prevented, so that it is possible to improve the convenience for the user.

  A rail member that is disposed outside the side surface of the suspension rack body and extends in the depth direction of the suspension rack body, a handle arm that extends in the width direction of the suspension rack body, and a lower part of the swing column. A connecting member to be connected, and a pulley disposed on the inner surface of the connecting member and traveling on the rail member, and swinging when the pulley travels on the rail member when the handle arm is gripped and operated. The column is slidable in the front-rear direction, and the lock mechanism includes a lock arm arranged along with the handle arm, a claw interlocking with the lock arm, and a locking hole provided in the suspension rack body. When the handle is separated from the handle arm, the claw is locked in the locking hole and is in a locked state.

  According to such a configuration, the swinging column and the suspension rack body can be moved up and down by gripping and operating the handle arm. Then, the lock mechanism is released by gripping the lock arm together with the handle arm, and when the gripped hand is released, the lock mechanism is activated and the lifting and lowering of the suspension rack body is stopped. Therefore, it is possible to operate and release the lock mechanism with a simple operation.

  The lock arm may be longer than the width of the hanging shelf body. In other words, the lock arm is approximately the same length as the handle arm. Thereby, since both the lock arm and the handle arm can be held at any position in the width direction of the elevating shelf, the operability can be improved.

  A plurality of the locking holes may be arranged on the movement trajectory of the claw. According to this configuration, since the handle arm can be fixed at a plurality of positions, the height at which the suspension rack body is stopped can be arbitrarily selected, and the convenience is improved.

  ADVANTAGE OF THE INVENTION According to this invention, the lifting shelf main body can be stopped in the middle position, the raising / lowering shelf which raised the user's convenience can be provided by preventing the sudden rise and sudden fall of a hanging shelf main body.

FIG. 3 is a diagram for explaining the operation when the hanging shelf body 200 is raised and lowered. In order to facilitate understanding, in FIGS. 2 and 3, the cover 220 a (see FIG. 1) fitted to the outside of the connecting member 230 is not shown. In addition, since the lifting shelf 100 has a bilaterally symmetric configuration, the following description mainly illustrates the configuration on the right side of the lifting shelf 100.

  As shown in FIG. 2A, swing columns 222a and 222b are attached to the left and right side plates 210 and 212 of the hanging shelf body 200 so as to be slidable in the front-rear direction. A connecting member 230 that connects the handle arm 220 extending in the width direction of the suspension rack body 200 and the swing columns 222a and 222b is attached to the lower part of the swing columns 222a and 222b. A handle arm 220 is attached to the lower end of the connecting member 230. When the user grips the handle arm 220 and operates it in the front-rear direction, the swinging pillars 222a and 222b move in the front-rear direction in conjunction with the handle arm 220. To do. The hanging shelf body 200 does not move in the front-rear direction.

  On the other hand, as shown in FIG. 1, a link mechanism 300 is attached to the inner surface of the side wall of the cabinet 110 (the right side is not shown in FIG. 1). As shown in FIG. 2B, the link mechanism 300 of this embodiment includes a first arm 312, a second arm 314, a third arm 316, and a fourth arm 318.

  The first arm 312 is an arm member that can swing up and down along an arcuate trajectory in which the tip bulges forward, and has one end connected to the upper end of the swing column 222a. On the other hand, the other end of the first arm 312 is connected to the base plate 302 and supported by the side wall of the cabinet 110 via the other end. The second arm 314 is a parallel arm that moves in parallel with the first arm 312, and one end is connected to the swing column 222 a and the other end is connected to the base plate 302 in the same manner as the first arm 312. That is, a parallelogram truss structure is formed by the base plate 302, the swing column 222 a, the first arm 312, and the second arm 314.

  The third arm 316 has one end connected to the first arm 312 and the other end connected to the fourth arm 318. The fourth arm 318 has one end connected to the third arm 316 and the other end connected to a spiral spring 320 accommodated in the base plate 302. As a result, the first arm 312 is connected to the spiral spring 320 via the third arm 316 and the fourth arm 318. The third arm 316 is connected to the outside of the axis of the first arm 312 and is pulled to rotate the first arm 312 upward. Therefore, the load on the hanging shelf body 200 and the stored items can be reduced, and the operation when the user houses the hanging shelf body 200 can be assisted.

  FIG. 3A illustrates a state in which the hanging shelf main body 200 is accommodated in the cabinet 110. As shown in FIG. 3A, in the state where the hanging shelf main body 200 is accommodated in the cabinet 110, the first arm 312 and the second arm 314 are in a position rotated upward. The first arm 312 is restricted from rotating forward by the urging force of the spiral spring 320 connected via the third arm 316 and the fourth arm 318.

  When the user grasps the handle arm 220 and pulls it forward from the state shown in FIG. 3A, the swing is connected to the handle arm 220 via the connecting member 230 as shown in FIG. The pillar 222a moves forward. Thereby, the 1st arm 312 and the 2nd arm 314 rotate toward the front, and the hanging shelf main body 200 descends.

  When the handle arm 220 is further pulled forward from the state shown in FIG. 3B, the first arm 312 and the second arm 314 are further rotated forward. When the first arm 312 passes the horizontal position, the handle arm 220 moves rearward as shown in FIG. Then, as shown in FIG. 3 (d), the first arm 312 and the second arm 314 are rotated rearward so that the swing column 222 a and the hanging rack body 200 are further lowered, and the hanging rack body 200 is moved outside the cabinet 110. It will be pulled out.

  As described above, in the lifting shelf 100 of this embodiment, the swinging column 222a slides in the front-rear direction by gripping the handle arm 220 and sliding it in the front-rear direction. As the swing column 222a moves in the front-rear direction, the arm members (the first arm 312 and the second arm 314) rotate while drawing an arcuate locus, and the suspension rack body 200 moves up and down in conjunction with the movement. To do. In this manner, the suspension rack body 200 can be lifted and lowered by the sliding movement of the handle arm 220 and thus the swing column 222a. For this reason, the storage thing accommodated in the hanging shelf main body 200 can be taken out easily, and it becomes possible to improve a user's convenience.

As shown in FIGS. 5A and 5B, the cross section of the first rail member 250 is a substantially U-shape that opens toward the outside in the width direction of the suspension rack body 200, A pulley 232 (to be described later) of the connecting member 230 is disposed inside the running groove 252 inside the door. An insertion groove 254 is formed inside the running groove 252 of the first rail member 250, and the second rail member 260 is inserted through the insertion groove 254.

  As shown in FIG. 5A, the second rail member 260 has the same length as the first rail member 250. When the second rail member 260 is attached to the insertion groove 254 of the first rail member 250, a plurality of locking holes 262 are arranged in the first rail member 250. Thereby, the latching hole 262 is provided in the hanging shelf main body 200.

  On the other hand, a pulley 232 is disposed on the connecting member 230 on the surface (inner surface) on the side facing the hanging shelf body 200. As the pulley 232 travels in the travel groove 252 of the first rail member 250 as shown in FIG. 5B, the swing column 222a can slide in the front-rear direction. Further, the connecting member 230 is formed with a through hole 234 through which a claw 412 formed in the lock member 410 described later is passed.

  As shown in FIG. 4, a lock member 410 is attached to the connecting member 230. In the present embodiment, the connecting member 230 and the lock member 410 are rotatably fixed by the fixing pin 402. A lock arm 420 disposed along with the handle arm 220 is connected to the lower end of the lock member 410. The lock member 410 has a claw 412 on the opposite side of the lock pin 420 with respect to the fixing pin 402. Therefore, when the lock arm 420 is moved, the claw 412 is also moved in conjunction with this movement. In the present embodiment, the lock mechanism 400 includes the claw 412, the locking hole 262, and the lock arm 420.

  6 and 7 are diagrams illustrating the operation of the lock mechanism 400. FIG. 6A and 6B are diagrams when the lock mechanism 400 is in a locked state, and FIGS. 6C and 6D are diagrams when the lock mechanism 400 is in a released state. FIGS. 6A and 6C show a state where the locking mechanism 400 is observed from the outside, and FIGS. 6B and 6D show a state where the locking mechanism 400 is observed from the inside. FIG. 7A is a cross-sectional view when the lock mechanism 400 is in a locked state, and FIG. 7B is a cross-sectional view when the lock mechanism 400 is in a released state.

  6A and 6B show a state where the user does not hold both the handle arm 220 and the lock arm 420. FIG. The lock member 410 is urged by the spring 414 with respect to the connecting member 230, and the handle arm 220 and the lock arm 420 are separated from each other if the lock member 410 is not gripped. In this state, as shown in FIG. 7A, the claw 412 of the lock member 410 is raised, the claw 412 is locked in the locking hole 262 of the rail member 240 (second rail member 260), and the lock mechanism 400 is It is locked.

  When the user grips both the handle arm 220 and the lock arm 420 from the above state, the handle arm 220 and the lock arm 420 are brought close to each other as shown in FIGS. As a result, as shown in FIG. 7B, the claw 412 of the lock member 410 is lowered, the claw 412 is released from the locking hole 262 of the rail member 240, and the locked state is released. Therefore, by grasping the lock arm 420 together with the handle arm 220, the swing column 222a can be slid in the front-rear direction, and the suspension rack body 200 can be moved up and down.

  At this time, even if the user's hand moves away from the handle arm 220 or the lock arm 420 while moving, the handle arm 220 and the lock arm 420 are separated by the urging force of the spring 414 as described above. The claw 412 of the member 410 is locked in the locking hole 262 of the rail member 240. Thereby, the lock mechanism 400 will be in a locked state and the raising / lowering of the hanging shelf main body 200 will stop. Therefore, the movement of the hanging shelf main body 200 can be restricted even at midway positions other than the use position and the storage position. By restricting the vertical movement of the hanging rack body 200 in this way, it is possible to work by stopping the hanging rack body at an intermediate position, and it is preferable to prevent sudden rise and drop of the hanging rack body 200 and to improve the user's convenience. It becomes possible to raise. In particular, when the suspension rack body 200 is moved up and down, the lock mechanism is released, so that the user does not have to be aware of the lock mechanism and can be handled easily.

  FIG. 8 is a detailed view of FIG. As shown in FIG. 5A, in the present embodiment, a plurality of locking holes 262 are formed in the longitudinal direction of the second rail member 260. Thereby, as shown in FIG. 8, a plurality of locking holes 262 are arranged on the movement locus of the claw 412 of the lock member 410. Accordingly, in the depth direction of the lifting / lowering shelf 100, the movement of the handle arm 220 and hence the swing column 222a can be restricted at a plurality of positions, and the user can arbitrarily select the lifting / lowering height of the hanging shelf main body 200. . Thereby, since the user can perform the work by stopping the movement of the hanging shelf main body 200 at a convenient height, the convenience can be improved.

  In this embodiment, as shown in FIG. 2A, the width of the lock arm 420 is longer than the width of the hanging shelf body 200. As a result, the width of the lock arm 420 is longer than that of the handle arm 220. Accordingly, since the lock arm 420 and the handle arm 220 can be held together at any position in the width direction of the lifting / lowering shelf 100, operability can be improved. In addition, since the widths of the lock arm 420 and the handle arm 220 are substantially the same, it is possible to enhance their unity and improve the appearance (aesthetics) of the lifting shelf 100.

  In the present embodiment, the lock mechanism 400 exemplifies a configuration including the claw 412 of the lock member 410 and the locking hole 262 of the rail member 240 (second rail member 260). However, the present invention is not limited to this. For example, a brake pad may be provided on the lock member 410, and the sliding movement of the swing column 222a and the lifting / lowering movement of the hanging rack body 200 may be regulated by contacting the brake pad and the rail member 240. As another means, it is possible to form a notch in the rail member 240 and to restrict the lifting and lowering of the hanging shelf main body 200 by hooking the lock member 410 to the notch.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
