Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet for mounting kitchen appliances such as a built-in stove mainly incorporated in a system kitchen.

[0002]

2. Description of the Related Art When incorporating a built-in type range into a system kitchen, the range is stored in a mounting cabinet and is inserted into the space under the countertop of the system kitchen, and the range is lifted up in the mounting cabinet. This is done by fastening the range to the lower surface of the suspension frame that is attached to the opening formed in the counter top.

As such a conventional mounting cabinet, for example, the one described in Japanese Utility Model Laid-Open No. 1-112315 is known. This mounting cabinet is constructed by suspending a pair of front and rear springs on each of the left and right sides of a box-shaped cabinet body, and suspending a mounting frame that is vertically assembled to each pair of springs. ing. Then, at the time of shipment, the range is placed so as to straddle the left and right placing frames, and in this state, the placing frame is pushed down against a spring to a predetermined lower end position and temporarily fixed by an appropriate stopper member. And support the range stably. Then, when this is incorporated into the system kitchen, the stopper member is removed, and the range is lifted up by using the biasing force of the spring.

[0004]

In the conventional mounting cabinet described above, the range is supported by a pair of left and right springs, a total of four springs. However, the biasing force of these springs with respect to the center of gravity of the range is applied. It is difficult to balance, the range tilts when lifting up and hits the hanging frame,
It may be difficult to connect the range to the suspension frame.

When the range is lifted up, the spring contracts by the same length as the lifted amount. For this reason, the biasing force of the spring becomes weak, and there is a problem that a desired biasing force cannot be obtained at the rising end position where it abuts the suspension frame. On the other hand, to eliminate this, use an extremely long spring,
It is necessary to use a spring with a strong biasing force. The use of a long spring is not preferable because the height of the cabinet body is restricted, and the use of a strong spring causes the spring to urge too much at the lower end position, and the range vibrates when the stopper member is removed. There was a risk that it could rise and collide with the suspension frame, damaging the stove.

The present invention makes it possible to vertically move the kitchen utensil in a horizontal position and to suppress the decrease of the biasing force of the spring due to the lift-up of the kitchen utensil as much as possible. Its purpose is to provide a mounting cabinet for kitchen appliances.

[0007]

In order to achieve the above object, the present invention provides a cabinet main body, and an X-shaped link mechanism which is provided in the cabinet main body and supports a kitchen appliance so as to be able to move up and down.
An urging means for urging the kitchen utensil upward through an X-shaped link mechanism, and the urging means is constituted by a spring long in the vertical direction, and is hung on the cabinet body at its upper end and at the lower end by X. It is characterized in that it is connected to at least one of a pair of links intersecting with the X-shape that constitutes the shape link mechanism.

[0008]

The kitchen appliance is supported by the X-shaped link mechanism and is moved up and down in the cabinet body while being urged upward by the urging means. Therefore, when the kitchen appliance is moved up and down, it maintains a horizontal posture by the action of the X-shaped link mechanism. It will be translated in the vertical direction and will not tilt. Further, if the biasing means is composed of a spring which is long in the vertical direction and is connected to at least one of the pair of links forming the X-shaped link mechanism at the lower end, the amount of movement (movement amount) of the kitchen appliance is higher than that of the kitchen appliance. The amount of vertical movement of a point on the link separated from the kitchen appliance becomes small. For this reason, the rate of decrease in the biasing force of the spring that accompanies the vertical movement of the kitchen utensil decreases, and even if the biasing force of the spring at the lower end position of the kitchen utensil is not set too strongly, the required biasing force at the rising end position can be obtained. Obtainable.

Although a pair of springs may be provided and the lower end of each spring may be connected to each of the pair of links of the X-shaped link mechanism, the number of springs may be reduced and the X-shaped link mechanism may operate smoothly. For this purpose, it is desirable to connect the lower end of the spring to the intersection of the pair of links.

First, in order to facilitate understanding of the subsequent structural description of the mounting cabinet, a method of using the mounting cabinet and the like will be briefly described with reference to FIG. The mounting cabinet 1 is a device for incorporating a built-in range R having a considerable weight into a so-called installation space S for the range of the system kitchen K, and is installed in the installation space S together with the range R.

The range R is composed of a stove C at the top and an oven O at the bottom, and is stored in the mounting cabinet 1 in a state where the main body is exposed at the time of shipping and is transported in this state. In the field, in this state, it is inserted into the space below the countertop T of the system kitchen K that constitutes the installation space S. Then, the range R is lifted up to a desired mounting position in the mounting cabinet 1, and the range R is attached to the hanging frame M attached to the opening Ta for the stove C formed in the countertop T at the portion of the stove C. Secure with screws.

As shown in FIGS. 1 and 2, the mounting cabinet 1 includes a frame-shaped box-shaped cabinet main body 2 and a pair of mounting frames 3 and 3 which are vertically movable on both left and right sides of the cabinet main body 2. , A pair of left and right X links 4 and 4 which are connected to the mounting frame 3 from below and constitute an X-shaped link mechanism.
And a pair of left and right springs 5 and 5 for urging the placing frame 3 upward. The range R is placed so as to straddle the placing frames 3 and 3, and the urging force of the springs 5 and 5 is set. Is lifted up by.

The cabinet main body 2 includes a pair of side frames 11 and 11 provided on both left and right sides, an upper girder 12 connecting the side frames 11 and 11 at a rear upper end portion thereof, and the side frames 11 and 11 respectively at front and rear lower end portions thereof. It is composed of a front girder 13 and a rear girder 14 which are connected with each other. Each side frame 11 is composed of a pair of columns 15 and 15 standing up and down, and an upper beam 16 and a lower beam 17 that connect the pair of columns 15 and 15 at upper and lower ends, respectively. As shown in FIGS. 3 and 5, the pair of columns 15 and 15 of the side frame 11 are made of "C" type channel material, and the channel grooves are assembled so as to face each other. The upper ends of the respective channel grooves are open, and the mounting frame 3 is engaged with the channel grooves of the columns 15 and 15 so as to be inserted from above and slidable in the vertical direction.

The upper beam 16 is made of a plate material and is assembled so as not to close the upper ends of the channel grooves of the columns 15. A hook hole 16a to which the upper end of the spring 5 is attached is formed in the middle lower portion of each upper beam 16, and each spring 5 is suspended downward from this hook hole 16a. On the other hand, the lower beam 17 is made of a "C" type channel material, and is assembled with the channel groove facing upward.
A guide hole 17a for the X link 4 is formed in the front portion of the side surface of the lower beam 17, and a shaft hole 17b for the X link 4 is formed in the rear portion. A moving shaft 18 and a fixed shaft 19 that connect the lower beam 17 and the X link 4 are attached to the guide hole 17a and the shaft hole 17b so as to be inserted therethrough. Is
Rollers 20, 20 are rotatably supported. That is, the moving shaft 18 and the fixed shaft 19 also serve as a connecting member that connects the lower end of the X link 4 to the cabinet body 2 and a support shaft of the roller 20. The mounting cabinet 1 can be easily moved on the floor surface in a factory or a site by the rollers 20.

As shown in FIGS. 4 and 5, each mounting frame 3 is composed of a rectangular frame body composed of an upper frame 21, a lower frame 22 and front and rear vertical frames 23, 23. A channel-shaped rail portion 23a that is received in the channel groove of each of the columns 15 is integrally formed on the frame 23, and the mounting frame 3 is attached to the rail portion 23.
At a, it is slidably engaged with the side frame 11 of the cabinet body 2 in the vertical direction. In the range R, the stove C is placed on the upper frame 21 of the placing frame 3 and the oven O is placed on the lower frame 22 of the placing frame 3, and these are fixed by screws and integrated with each other in an integrated state. (See FIG. 1). Upper frame 21
Is made of a plate material having an L-shaped cross section, and one side of the vertical frame 2 projects to the inside of the cabinet body 2.
It is attached to 3,23. And this upper frame 21
The stove C of the range R is placed on the overhanging portion of.

The lower frame 22 is constructed by stacking a support plate 24 and a connecting plate 25, both of which have an L-shaped cross section. One side of the support plate 24 projects to the inside of the cabinet body 2, and the oven O of the range R is placed on this portion. On the other hand, the connecting plate 25 is formed with a front connecting piece 26 and a rear connecting piece 27, which are formed by cutting and bending two sides downward in a U-shaped cross section at two front and rear portions. The upper ends are connected. The side surface of the front connecting piece 26 has a guide hole 1 for the lower beam 17.
A guide hole 26a of the same shape corresponding to 7a is formed, and the moving shaft 28 is attached so as to pass through the guide hole 26a. Similarly, a shaft hole 27a corresponding to the shaft hole 17b of the lower beam 17 is formed on the side surface of the rear connecting piece 27,
A fixed shaft 29 is attached to the shaft hole 27a.

Each X-link 4 has a pivot 3 forming an intersection.
1 and a first link 32 and a second link 33 that are rotatably connected to each other in an "X" shape around this pivot 31. The lower frame 22 of the mounting frame 3 has an upper end portion. And is connected to the lower beam 17 of the cabinet body 2 at the lower end. The first link 32 is made of a “C” type channel material, and the second link 33 is made of a “C” type channel material which is slightly narrower than the first link 32. The back surface of the middle portion of the first link 32 is cut out, and the second link 3 is cut in this portion.
Both links 32 and 33 are connected in an "X" shape so that 3 is inserted (see FIG. 2).

The upper ends of the first and second links 32, 33 are pivotally and slidably attached to the guide holes 26a of the lower frame 22 of the mounting frame 3 via the moving shafts 28 so that the second links 33 can pivot. The first link 32 is rotatably supported by the shaft hole 27a of the lower frame 22 via the fixed shaft 29. Similarly, at the lower ends of the first and second links 32 and 33, the first link 32 pivotally and slidably supports the guide beam 17a of the lower beam 17 of the cabinet body 2 through the moving shaft 18. The second link 33 is rotatably supported by the shaft hole 17b of the lower beam 17 via the fixed shaft 19.

As a result, the first and second links 32,
When 33 opens and closes (rotates) around the pivot 31, the moving shafts 18 and 28 slide horizontally,
The lower frame 22 of the mounting frame 3 is moved vertically with respect to the lower beam 17 of the cabinet body 2 while maintaining the parallel state.
Therefore, the range R mounted on the mounting frame 3 is vertically moved up and down while maintaining the horizontal posture. In this case, the connecting portion of the first and second links 32, 33 by the pivot 31 is located at an intermediate position in the longitudinal direction of each of the links 32, 33, and with respect to the vertical movement amount of the mounting frame 3. The amount of vertical movement of the pivot 31 is half that amount. With this in mind, the lower end of the spring 5 is attached to the pivot 31.

Each of the springs 5 is composed of a relatively long coil spring, and is hooked at the upper end to the hook hole 16a of the upper beam 16 of the cabinet body 2, and at the lower end is a pivot that constitutes the intersection of the X-links 4. It is hooked on the outer end of 31 (see FIG. 7). As a result, the mounting frame 3 is biased upward via the X link 4. That is, the mounting frame 3
The range R mounted on is elastically supported by springs 5 and 5 suspended from upper beams 16 and 16, and is biased upward. The biasing force of the spring 5 in this case is set so that the range R can be raised to a desired mounting position where the range R is assembled to the system kitchen K at the rising end position of the mounting frame 3 where the biasing force and the weight of the range R are balanced. Has been done.

On the other hand, when the range R is shipped, the mounting frame 3 is pressed against the spring 5 to a desired lower end position and temporarily fixed, and the range R is fixed.
I am trying to store it stably. The temporary fixing is performed by the restraint means 6 incorporated inside the upper end of each X link 4 (see FIG. 2). The spring 5 is attached when the mounting frame 3 is incorporated into the side frame 11 of the cabinet body 2. That is, the X-link 4 is attached to the mounting frame 3 in advance, and in this state, the mounting frame 3 is inserted into the cabinet body 2 from above until the distance between the hook hole 16a and the pivot 31 does not exceed the free length of the spring 5. Then, both ends of the spring are attached to the hook hole 6a and the pivot 31. When the spring 5 is attached, the lower end of the X-link 4 is the lower beam 17
The mounting frame 3 is pushed down to a position where the X-link 4 is attached to the lower beam 17. In this case, when the upper frame 21 of the mounting frame 3 is completely inserted into the side frame 11, for example, a pin is screwed through a hole provided in the upper end of the front surface of the support column 15 to mount the upper frame 21 from the upper end of the side frame 11. It is advisable to prevent the mounting frame 3 from coming off.

As shown in FIGS. 6 and 7, the restraint means 6
Is configured by utilizing the connecting portion between the upper end of the second link 33 and the lower frame 22 of the mounting frame 3, that is, the moving shaft 28. The moving shaft 28 inserted into the guide hole 26a of the front connecting piece 26 of the lower frame 22 is composed of a head portion 28a and a shaft portion 28b, and the tip of the shaft portion 28b projects to the inside of the cabinet body 2. The manual lever 42 is horizontally attached to the projecting portion of the moving shaft 28 via the penetrating pin 41 to form the restraint means 6. The lever 42 is rotatably supported by the penetrating pin 41 at the base portion 43, and is rotated between an unrestrained position by an opening operation and a restricted position by a closing operation. In the unrestrained position, the base 4 of the lever 42
The third contact surface 43a contacts the side surface of the front connecting piece 26, and the second contact surface 43b of the base portion 43 contacts the side surface of the front connecting piece 26 at the restrained position. 43a, 43
The front connecting piece 26 is sandwiched between b and the head portion 28a of the moving shaft 28.

The distance between the second contact surface 43b and the penetrating pin 41 is somewhat longer than the distance between the first contact surface 43a and the penetrating pin 41, and the second contact surface 43b has the front connecting piece. When it is in contact with 26, a compression force that compresses the front connecting piece 26 is applied. On the other hand, the moving shaft 28
Is supported by the front connecting piece 26, the upper end of the second link 33 is sandwiched inside the front connecting piece 26, and the spacer 44 is sandwiched in the channel groove of the second link 33. Therefore, when the lever 42 is rotated to the restraining position, the rotational movement of the second link 33 is restrained by the frictional force generated by the compression force between the front connecting piece 26 and the spacer 44. When 42 is rotated to the non-restraint position, this constraint is released. Accordingly, the sliding of the mounting frame 3 can be appropriately restrained, the range R can be stably supported during transportation, and the range R assembled in the system kitchen K can be fixedly supported on the cabinet 1 side. It is like this.

Here, with reference to FIGS. 1 and 2, the assembling of the range R into the system kitchen K will be described step by step. In order to store the range R in the cabinet body 2 at the time of shipping, first, the levers 42 of the restraint means 6 are opened to the non-restrained position so that the mounting frame 3 can be slid. The stove C and the oven O are placed so as to straddle both the left and right placing frames 3 and 3, respectively, and they are screwed together and integrated. Next, the placing frame 3 is lowered against the spring 5, and the placing frame 3 is pushed down until the desired lowering end position is reached. In this state, both levers 42,
The range R is stably supported by closing 42 to the restraining position. Then, add accessories such as gas pipes and hoods to the range R
Attach to, pack and transport to the site. In this case, the procedure may be such that the placing frame 3 is pushed down to the descending end position against the spring 5 and temporarily fixed by the restraining means 6, and then the stove C and the oven O are placed.

In the field, after unpacking, the range R is inserted into the installation space S for the range of the system kitchen K together with the mounting cabinet 1. After the mounting cabinet 1 is inserted into the installation space S, the range R is pressed from above and both levers 42, 42 are opened. When the restraint of the mounting frame 3 is released, the range R is increased by energizing the spring 5. Then, the range R is screwed to the hanging frame M attached to the opening Ta of the countertop T at the stove C. Here, again, both levers 42, 4 of the restraint means 6 are
2 is operated to be closed so that the range R is supported by the mounting frame 3. Finally, the front decorative plate P is assembled to the system kitchen K, and the work is completed.

As described above, according to this embodiment, the range R is mounted on the mounting frame 3 connected to the X link 4 and is moved up and down. R can be raised and lowered in a horizontal position. Therefore, when the range R is stored in the cabinet body 2 or assembled in the system kitchen K, the range R does not tilt, and these operations can be performed extremely efficiently. At the same time, the mounting frame 3 does not tilt, and the side frame 11
It can be slid smoothly even if the fit with is weak.

The lower end of the spring 5 is connected to the pivot 3 of the X-link 4.
Since it is attached to No. 1, a uniform biasing force can be exerted by one spring 5 in the longitudinal direction of the mounting frame 3, and the range R can be lifted up in a well-balanced manner. Moreover, since the movement amount of the pivot 31 is half of the movement amount of the mounting frame 3, that is, the range R in the vertical direction,
The reduction rate of the biasing force of the spring 5 due to the vertical movement of the range R is suppressed, and even if the biasing force of the spring 5 is not set so strongly,
Further, even if the ascending / descending distance is long, the required biasing force can be obtained at the rising end position.

In this embodiment, the urging means is composed of one spring attached to the pivot of the X-link. However, a pair of springs are provided and the lower end of each spring is the first and the first of the X-link. The two links may be locked to the respective parts near the lower ends. Also, connect two or more X links up and down,
The lower end of the spring may be locked to the lower X link. By doing so, the rate of decrease in the biasing force of the spring is further suppressed.

[0029]

As described above, according to the present invention, since the kitchen utensil is supported by the X-shaped link mechanism so as to be able to move up and down, the kitchen utensil does not tilt when moving up and down, and the kitchen utensil can be installed in the system kitchen or the like. The kitchen appliances can be assembled smoothly. In addition, the spring that constitutes the urging unit is
Since it is connected to at least one of the links of the shaped link mechanism, it is possible to obtain the required urging force for lifting up the kitchen equipment without using a spring with a very strong urging force, thus improving workability. Has the effect that can.
