Description

Lifting cabinet

The present invention relates to a lift cabinet disposed above a kitchen appliance.

In the galley, since there is a space in the upper part of the conditioning equipment such as a kitchen, there are many cases where the hanging cabinet is placed above the kitchenware. In the kitchen, various utensils such as bowls, plates, cups, and the like, utensils such as pots and pans, and seasonings such as salt and pepper are used. Therefore, these food utensils, conditioning instruments, seasonings, and the like are accommodated in the above-mentioned wall cabinet.

Moreover, with the diversification of lifestyles and eating habits, the above-mentioned food utensils, conditioning equipment, seasonings, and the like tend to increase. With the aging of today, there is also a demand for excellence and convenience in the use of the above-mentioned wall cabinets.

Thus, there is generally provided a lift cabinet that uses manual or electric power to lift a rack located above. For example, the lift cabinet is provided with a lifter (for example, Japanese Patent Document 1), and after opening the door panel disposed in front of the cabinet, the swing arm is used to support the storage rack provided in the cabinet and simultaneously pulled down to The lower side (for example, Japanese Patent Document 2), the kitchen cabinet, and the lifter that can be vertically moved up and down from the kitchen cabinet (for example, Japanese Patent Laid-Open No. 3).

In the structure described in Japanese Patent Laid-Open Publication No. 1, the lifting device becomes large and large, and the lifting device is seen from the outside. Institutions, so there will be problems that are difficult to enhance aesthetics. On the other hand, in the structure described in Japanese Patent Laid-Open No. 2, since the storage rack that is pulled down is rotated downward toward the conditioner, the conditioning work becomes troublesome, and it is necessary to frequently pick up and place the storage rack, which is a problem that is troublesome. Therefore, in recent years, as described in Japanese Patent Laid-Open No. 3, a structure having a lifting frame that can be vertically moved up and down from a kitchen cabinet is often used.

However, in the structure in which the vertical direction is raised and lowered, in order to expose the entire surface of the lifting frame, it is necessary to lower the entire lifting frame to the lower side of the kitchen cabinet below the kitchen cabinet. In other words, it becomes only a half-height hanging cabinet among the spaces used in the cabinets above the kitchen to the ceiling. In addition, since the driving mechanism for lifting and lowering must be installed in the kitchen cabinet, the volume change of the lifting frame is small. Furthermore, the height of the general household ceiling is generally about 2.3 m, and the height of the kitchen utensil is about 85 cm. It is even more necessary to leave a storage room on the kitchen cabinet and a height for placing small items. Moreover, if less than half of the height of the remaining upper space is the height of the lifting frame, the volume of the upper lifting frame can be said to be insufficient.

Therefore, since the past, a switch has been disclosed in which the front door piece of the kitchen cabinet and the up and down movement of the lifting frame are linked together, and in the state of descending the lifting frame, the upper end of the lifting frame is located above the lower end of the kitchen cabinet (for example, Japan). Patent Document 4). According to this configuration, since the height can be increased from the position where the front door piece is staggered, the height of the lifting frame can be increased, and the lifting frame having a large volume can be provided in the upper space of a limited height.

[Patent Document 1] Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. [Patent Document 3] JP-A-2006-000677 [Patent Document 4] JP-A-2006-340756

However, in the structure described in Patent Document 4, since the lower end of the door piece is a structure that is rotationally opened, the front open space is small. Therefore, in particular, the upper section of the crane has a problem that it is difficult to take a large item such as a pan or a storage box. Although it is also considered to open the door piece larger, in order to greatly open the door piece in front of the wall cabinet, the front plate is pressed against the head, which has the feeling of giving a sense of oppression.

Accordingly, an object of the present invention is to provide a lift cabinet that shortens the stroke of the lower lift frame and increases the volume while keeping the pressure feeling with the operation of the door to a minimum.

In order to solve the above problems, a representative structure of the elevating wall cabinet according to the present invention includes a kitchen cabinet having a bottom surface and an open front surface, and a lifting frame supported by the kitchen cabinet, and is disposed above the kitchenware. The lifting type hanging cabinet is characterized in that: a door piece disposed on the upper side of the kitchen cabinet and above, and a lower door piece disposed in front of the kitchen cabinet and below, the lower door piece is transferred to the lower end of the upper door piece, Rise in a way along its surface.

According to the above configuration, it is possible to provide a shortening of the stroke of the descending crane, and to increase the volume while staying in the pressure with the action of the door. At the minimum lift cabinet.

An upper guide portion and a lower guide portion are respectively disposed on both side edges of the lower door piece, and upper guides for guiding the upper guided portion and lower guides for guiding the lower guided portion are respectively disposed on both side walls of the cabinet. The upper guide and the lower guide may further include an inclined portion that is guided toward the front of the kitchen cabinet as the upper guided portion or the lower guided portion moves upward from the stop position, and the inclined portion that is continuous toward the inclined portion A straight line that is guided in the vertical direction.

According to the above configuration, the lower door piece can be moved upward, and the inclined portion first moves toward the front of the kitchen cabinet, and then rises along the front side of the upper door piece. Thereby, the lower door piece is transferred to the lower end of the upper door piece to rise along the surface thereof.

The inclination with respect to the straight line of the lead is preferably that the inclined portion of the upper guide is larger than the inclined portion of the lower guide. Thereby, the upper end of the lower door piece is moved to the front of the kitchen cabinet more than the lower end, and can be smoothly transferred to the lower end of the upper door piece.

In the foregoing upper guide member or lower guide member, when the horizontal distance from the stop position of the upper side guided portion or the lower side guided portion to the straight portion is the extension width, the extension width of the upper guide member is longer than the extension width of the lower guide member. should. Thereby, the lower door piece is raised with a more inclined state in which the upper end thereof is more prominent. Therefore, it is possible to ensure the expansion to the maximum space on the user's head, and it is possible to prevent a feeling of pressure due to the lower door piece.

Further, it is also possible to configure a traction portion that pulls the lower door piece and raises it, and the lower door piece is lowered by its own weight by releasing the traction by the traction portion. Although it is also considered to use a motor, a gear, or the like, the above-described rail guide and the structure of the guided portion can be used to reduce the traction and the use of the self-weight. In order to carry out the lifting operation, the driving mechanism is simplified.

The traction portion may be formed by a pulley and a cable body that suspends the lifting frame and the lower door piece at both ends via a pulley, and the lower door piece is pulled by the load when the lifting frame is lowered. Thereby, since the lift frame and the lower door piece are mechanically interlocked, the driving force for raising and lowering the lower door piece can be supplied by the drive source of the lift frame.

According to the present invention, it is possible to provide a lift cabinet that shortens the stroke of the descending crane and increases the volume while keeping the pressure feeling with the operation of the door to a minimum.

[Best form for implementing the invention]

Hereinafter, the best mode for carrying out the invention will be described in detail with reference to the drawings. In the detailed description and the drawings, the components that have the same functional structure are denoted by the same reference numerals, and the description thereof will not be repeated. In addition, the dimensions, materials, other specific numerical values, and the like shown in the following embodiments are merely examples for facilitating the understanding of the present invention, and are not intended to limit the present invention, particularly in the case of a prior setting.

In the present embodiment, the lifting frame of the kitchen lift cabinet (hereinafter referred to as "hanger") is interlocked with the lower door piece before the lifting of the lifting frame, so that the two devices move toward each other in the reverse direction. Thus, although not lengthened The descending stroke of the frame fully ensures the open space in front. Further, the lower door piece has a feature that it is transferred to the lower end of the upper door piece as it rises, and rises along the surface thereof. Here, in order to facilitate the understanding of the present embodiment, first, the arrangement and driving mechanism of the wall cabinet will be described, and the features of the embodiment will be described in detail.

Fig. 1 is a perspective view showing the positional relationship between the system kitchenware and the wall cabinet of the embodiment. The system kitchenware 100 is centered on the fire (heating) or water required for conditioning, and the conditioning apparatus is disposed in each storage tank in accordance with the size thereof. Although the wall cabinet 110 is disposed above the system kitchen appliance 100, the door cannot be opened and closed, and the storage portion is lowered to the height of the eyes of the kitchen user, and the hand is extended to the front to receive or take out the stored object.

The system kitchenware 100 is composed of three parts of the water tank 130, the conditioning space 140, and the oven 150. In such a system kitchenware 100, the wall cabinet 110 is fixedly supported by the wall 500 above the area corresponding to the width of the water tank 130 and the conditioning space 140. On the other hand, above the oven 150 for treating the flame, adjacent to the wall cabinet 110, the range hood 160 is fixedly supported by the wall 500 in the same manner as the wall cabinet.

The wall cabinet 110 includes a kitchen cabinet 107 that is open below, and a lifting frame 180 that moves up and down the kitchen cabinet 170 toward the inside and outside of the kitchen cabinet 170. The lifting frame 180 has a storage portion, and most of the front surface is open, and can take the contents of the food container or the kitchen.

Further, a front door piece 172 and a lower door piece 174 are disposed in front of the kitchen cabinet 170. When the lifting frame 180 is lowered below the kitchen cabinet 170, the lower door piece 174 moves upward together with the lower door piece 174. Therefore, the lifting frame 180 The upper end will be lower than the lower end of the kitchen cabinet 170, and the open front of the lifting frame 180 will appear in front of the user's eyes. With such a configuration, the movable range of the crane frame 180 can be narrowed, the time for the lifting operation can be shortened, or the size of the height direction of the wall cabinet 110 can be increased to increase the volume. Hereinafter, a description will be given of a drive mechanism for causing the lift frame 180 to interlock with the lower door piece 174.

(drive mechanism of the lifting frame)

Fig. 2 is a view showing a drive mechanism of the lift frame 180. Here, the lifting operation of the lifting frame 180 is mainly explained, and the front side of the hanging cabinet 110 is observed. Further, for the sake of easy understanding, the illustration of the lower door piece 174 is omitted in FIG.

First, the two wide cable bodies 200 are wound from the drive pulley 192 in the horizontal direction by the rotation of the drive motor 190. The wide cable body 200 is steered in a vertical direction by a diverting pulley 210 fixedly disposed in the vicinity of the side plates of the kitchen cabinet 170 as a fixed pulley, and the winding end portions are respectively fixed to the lifting frame 180 as a movable pulley. The function of the lifting pulley 212 is fixed above the kitchen cabinet 170. Therefore, the lifting and lowering of the crane frame 180 can be performed by rotationally driving the drive motor 190. Here, the cable body is not limited to a rope, but also includes a belt body.

As a result, if the lifting frame 180 is lowered, the accommodating portion 220 appears from the back surface of the lower door piece 174 (not shown).

(Drive mechanism of the lower door piece)

Figure 3 is a view showing the lower door piece 174 interlocked with the lifting frame 180. Diagram of the drive mechanism (traction). Such a third figure is to view the wall cabinet 110 from the side. Here, the lower door piece 174 is further moved up and down in conjunction with the lifting frame 180 shown in FIG.

Fig. 3(a) shows a state in which the lift frame 180 is housed in the kitchen cabinet 170. A lower door pulley 250 that is a fixed pulley is fixedly disposed between the lift frame 180 and the lower door piece 174. The lower door piece is connected to the two reels (the first reel 252 and the second reel 254) by the pulley 250, and the shafts are equally rotatably pivotally supported. Further, the first wire body 260 that suspends the crane frame 180 is wound around the first reel 252, and the second wire body 262 that suspends the lower door piece 174 is wound around the second reel 254.

Here, since the first cable body 260 and the second cable body 262 that respectively suspend the lift frame 180 and the lower door piece 174 are mutually reversely wound with respect to the reel, once the lift frame 180 or the lower door piece 174 is If one side rises, the other side will move together and fall because of its own weight.

Fig. 3(b) shows a state in which the crane 180 is taken out (dropped) from the cabinet 170. When the lift frame 180 is guided by the guide rail 264 and descends, the first cable body 260 pulls the first spool 252, and the second spool 254 coupled to the first spool 252 rotates only the first spool 252 around the rotation shaft 256. The same amount of angle. Then, the connecting portion 266 and the lower door piece 174 which are connected to the second cable body 262 are raised by the winding tension of the second reel 254. Therefore, since the lower door piece 174 rises in accordance with the lowering of the lift frame 180, and the sum of the movement amounts becomes the open space of the lift frame 180, the open space in front of the lift frame 180 can be sufficiently ensured without lengthening the down travel.

At this time, since the load of the lift frame 180 and the lower door piece 174 will rotate Since the shafts 256 are biased against each other in the center, the tensions for rotating the first reel 252 and the second reel 254 are offset each other, and the load for moving and maintaining the lifting frame 180 and the lower door piece 174 at an arbitrary position can be reduced. It can save energy and reduce costs.

Further, when the pulley 250 for the door piece is viewed in the third drawing, it is understood that the diameters of the winding portions of the first reel 252 and the second reel 254 are not the same. With such a configuration, the lift stroke ratio of the lift frame 180 and the lower door piece 174 can be arbitrarily set in accordance with the use of the wall cabinet 110.

In particular, in FIG. 3, the diameter of the second reel 254 around which the cable body that suspends the lower door piece 174 is wound is smaller than the diameter of the first reel 252 in which the cable body around which the suspension frame 180 is wound. As shown in Fig. 3, the wall cabinet 110 is assumed to have a certain amount of space that can be occupied below, and is not provided above. Therefore, although the lifting frame 180 can lower its height H1, it can only rise about half the length H2 of the lifting frame until the lower door piece overlaps the upper door piece. The ratio of the diameter of the second reel 254 corresponding to such a lower door piece 174 to the diameter of the first reel 252 corresponding to the lift frame can be, for example, H ₂ /H ₁ , H ₁ =450 mm, and H ₂ =200 mm. The diameter ratio is 4/9. In this manner, the diameter of the second reel 254 is smaller than that of the first reel 252, and the above-described stroke difference can be realized without using another special mechanism.

(combined from the drive motor)

As described above, the lift frame 180 is lifted and lowered with the drive motor 190 as a power source, and the lower door piece is lifted by the lift frame 180 as an indirect power source. drop. With such a configuration, the lifting and lowering of both the lift frame 180 and the lower door piece 174 can be controlled by one power source (drive motor).

Fig. 4 is an explanatory view of a comparison of a drive mechanism using the drive motor 190 and a drive mechanism using the lift frame 180. Here, the mechanism for transmitting power to the lift frame 180 by the drive motor 190 is independent of the mechanism for transmitting power to the lower door piece 174 by the lift frame 180, and the direction of transmission of each power can be restricted to the surface direction. For example, since the mechanism for transmitting power to the crane 180 by the drive motor 190 can only be achieved by the steering on the YZ plane, the communication mechanism can be realized by the combination of the cable body and the pulley. Similarly, the mechanism for transmitting power to the lower door piece 174 by the lifting frame 180 can only be achieved by the combination of the cable body and the pulley on the ZX surface.

With the above configuration, the lower door piece 174 can be pulled upward by the load at the time of the lowering of the lift frame 180. Since the lifting frame 180 and the lower door piece 174 are mechanically interlocked as described above, the driving force for raising and lowering the lower door piece 174 can be supplied by the driving source of the lifting frame 180. Further, since the lower door piece 174 cannot directly receive power from the drive motor 190, the lower door piece 174 is also stopped in conjunction with the case where the lift frame 180 cannot be lifted or lowered due to any accident. Therefore, instead of the lift frame 180, only the lower door piece 174 will act, and secondary damage will not occur.

(the guiding mechanism of the lower door piece)

Next, the guiding mechanism and action of the lower door piece will be described. Fig. 5 is a view for explaining a guiding mechanism of the lower door piece.

Fig. 5(a) is an exploded view showing the guiding mechanism. In the lower door piece 174 A door drive unit 176 for attaching the lower door piece 174 is attached to the joint portion 266 on the back side of the both side edges. The connecting portion 266 is provided with an upper roller 268 as an upper guided portion and a lower roller 270 as a lower guided portion. Further, a hanging portion 272 for attaching the second cable body 262 is provided at the upper end of the coupling portion 266. Guide assemblies 280 are provided on each of the two side walls of the cabinet 170. The guide member 280 is provided with an upper guide 282 for guiding the upper roller 268 and a lower guide 284 for guiding the lower roller 270. Further, the guide unit 280 is provided with a housing mechanism 390 which will be described later.

Large diameter portions 282a and 284a are formed at the lower ends of the upper guide 282 and the lower guide 284, respectively, and the heads of the upper roller 268 and the lower roller 270 can be inserted. Further, each of the guide members is provided with the inclined portions 282b, 284b which are moved upward from the stop position (substantially lower end position) of the upper roller 268 or the lower roller 270, and are guided toward the front of the kitchen cabinet 170, and are connected to The inclined portions 282b and 284b are substantially straight portions 282c and 284c that are guided in the vertical direction.

The upper guide 282 and the lower guide 284 are formed in the above shape, so that as the lower door 174 moves upward, the lower door 174 moves to the front of the kitchen cabinet by the inclined portions 282b and 284b, and then the straight portion 282c and 284c rise along the front side of the upper door piece 172. Thereby, the lower door piece 174 is transferred to the lower end of the upper door piece 172 to rise along the surface thereof.

Fig. 5(b) is an assembled view of the guiding mechanism. The upper roller 268 and the lower roller 270 are slidably fitted to the upper guide 282 and the lower guide 284. The second wire body 262 is suspended from the hanging portion 272 of the joint portion 266, thereby stopping the lower door piece 174. From the stop position, the second cable body pulls the connecting portion 266 upward, whereby the upper roller 268 and the lower roller 270 It will be guided by the upper guide 282 and the lower guide 284, while the lower door 174 will rise.

Fig. 6 is a view for explaining the operation of the lower door piece, and the operation of the lower door piece will be described with reference to the shape of the guide of Fig. 5(b).

Fig. 6(a) shows the state in the stop position. From this state, the second cable body 262 is pulled, whereby the lower door piece 174 starts to operate. At this time, as shown in FIG. 5(b), the inclination with respect to the straight line of the lead is such that the inclined portion 282b of the upper guide 282 is larger than the inclined portion 284b of the lower guide 284. Thereby, as shown in Fig. 6(b), the upper end of the lower door piece 174 starts moving toward the front of the kitchen cabinet more than the lower end. Further, as shown in Fig. 6(c), when the upper end of the lower door piece 174 is moved forward more than the lower end of the upper door piece 172, up to the upper roller 268 and the lower roller 270 to the straight portions 282c, 284c, such as As shown in Figure 6(d), it starts to rise. When the upper ends of the straight portions 282c and 284c are raised, as shown in Fig. 6(e), the upper side of the lower door piece 174 and the lower side of the upper door piece 172 are overlapped.

Fig. 7 is a view for explaining the locus of the lower door piece 174, the joint portion 266, the upper roller 268, and the lower roller 270. Referring to Fig. 7, it is understood that the upper end of the lower door piece 174 is transferred to the lower end of the upper door piece 172, and the lower door piece 174 is raised along the surface of the upper piece 172.

After the upper roller 268 and the lower roller 270 reach the straight portions 282c and 284c, the posture (inclination angle) of the lower door piece 174 is kept unchanged. Here, as shown in Fig. 5(b), the horizontal distance from the stop position of the roller 268 above the upper guide 282 to the straight portion 282c is the extension width w1, and the stop position of the roller 270 from the lower guide 284. Horizontal distance to the straight portion 284c To stretch the width w2. Further, in the present embodiment, the pull-out width w1 of the upper guide is set longer than the pull-out width w2 of the lower guide.

Thereby, the lower door piece 174 is raised in a state where the upper end is pulled out more and pulled out to the front of the kitchen cabinet, and the posture is maintained during the stop period. Thereby, it is possible to ensure a space that is expanded to the maximum extent on the user's head, and it is possible to prevent a feeling of pressure due to the lower door piece.

When the lower door piece 174 is closed, that is, when the lifting frame 180 is raised, the lower door piece 174 is reversed by the rising process shown in FIG. 6 and is stored below the upper door piece 172. At this time, by the action of the housing mechanism 390, it is finally closed.

The structure and operation of the housing mechanism 390 will be described. As shown in Fig. 5(a), the housing mechanism 390 includes an arm 390a that is provided at an upper portion of the guide unit 280 and that is rotatably supported by the intermediate portion at the guide unit 280, and a roller that is disposed at one end of the arm. The sub-390b and the spring 390c (pushing means) for pushing the bouncing roller 390b toward the inside of the cabinet. On the other hand, the connecting portion 266 is provided with a housing guide 266a for moving the roller 390b of the housing mechanism 390. The accommodation guide 266a has a groove shape having a U-shaped cross section, and the roller 390b abuts against the side wall thereof, whereby the elastic connection portion 266 can be pushed toward the inside of the kitchen cabinet.

When the lower door piece 174 is raised as described above, as shown in Fig. 6, since the roller 390b abuts against the side wall of the accommodating guide 266a, the accommodating mechanism 390 rotates against the urging force of the spring 390c. Further, when the upper roller 268 and the lower roller 270 are in the straight portion, since the pushing force of the housing mechanism 390 is substantially orthogonal to the direction of the guide groove, there is no obstruction of the lifting force. Hey. Further, when the lower door piece 174 is closed, in particular, when the upper roller 268 and the lower roller 270 are positioned at the inclined portions 282b and 284b, the spring force of the spring 390c of the housing mechanism 390 acts on the direction in which the lower door piece 174 is accommodated.

Here, it is assumed that since the lower door piece 174 is closed only by its own weight, and the upper roller 268 and the lower roller 270 are formed in the inclined portions 282b and 284b, a force is formed, and the force in the direction of accommodation is weakened. Therefore, the lower door piece 174 does not close at the end, and the movement ends when the upper door piece 172 is slightly floated. However, since the storage mechanism 390 having the above-described structure is provided, the upper end of the coupling portion 266 is particularly pushed toward the inside of the kitchen cabinet 170, so that the lower door piece 174 can be reliably received under the upper door piece 172.

As described above, the wall cabinet 110 of the present embodiment can sufficiently ensure the front open space without lengthening the lowering stroke of the lift frame 180, shorten the stroke of the lower lift frame, and increase the volume. In addition, the lower door piece will be transferred to the lower end of the upper door piece and rise along the surface thereof, thereby being able to increase the use of the kitchen lift cabinet with the pressure of the door action being kept to a minimum. Convenience.

Hereinabove, the description has been made with reference to the drawings and the preferred embodiments of the invention, but the invention is of course not limited to such examples. It is to be understood that those skilled in the art will recognize that various modifications and changes can be made without departing from the scope of the invention.
