Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shelf device, and more particularly to a shelf device that can change the front and back and vertical positions of food storage shelves, containers, cupboards, or storage shelves such as kitchens and warehouses provided in a refrigerator storage room.
[0002]
[Prior art]
In recent years, for example, refrigerators and kitchen storage shelves tend to have a larger storage capacity along with the diversification of eating habits, and particularly in household refrigerators, the class with storage capacity exceeding 400 liters has become mainstream. The outer height dimension is about 180 cm, and the width dimension and the depth dimension tend to increase.
[0003]
Along with this, the storage capacity of each storage room such as a refrigerated room and a vegetable room has also been expanded. However, as shown in FIG. A refrigerator compartment 52 having a large article storage capacity is arranged, and a vegetable compartment 53 and a freezer compartment 54 are arranged below it. The refrigerator compartment 52 is closed openably by a door 56 pivotally supported on one side of the front opening thereof, and the vegetable compartment 53 and the freezer compartment 54 are doors for convenience of taking in and out the stored items. It is a drawer type with a container attached to the storage room side.
[0004]
The refrigerating chamber 52 is provided with mounting shelves 55 that divide the room into a plurality of upper and lower stages, and are configured to store and store food stocks on the respective mounting shelves.
[0005]
However, as described above, since the refrigerator main body height is about 180 cm and the refrigerator compartment 52 is arranged at the upper part of the main body, the bottom position of the uppermost shelf 55 in the refrigerator compartment is about 160 cm from the floor surface. Since the dimensions are deep, it is not only difficult for a person with a short height to store and take out food from the uppermost shelf 55, but it is also difficult to check the storage state. It was a very difficult space to use.
[0006]
[Problems to be solved by the invention]
In order to solve the above problems, the applicant invented a shelf apparatus that moves the uppermost shelf forward and then moves it downward (Japanese Patent Application No. 2002-214422), but places a certain amount of food on the shelf container. Then, the shelf container stops at the lowest point, and if the user forgets to return the shelf container to the original position and closes the door, the shelf container collides with the door or door pocket and A large load is applied to the support shaft portion that supports the shaft.
[0007]
In particular, when a heavy food product is placed only in front of the shelf container, the front of the shelf container will be inclined downward, and if it collides with a door or door pocket at this time Since the front part of the shelf container is further stressed downward, there is a problem in that a large load is applied to the support shaft part and it is damaged.
[0008]
The present invention has been made in consideration of the above points, and a shelf device that suppresses a load applied to a support shaft portion even when a strong impact is applied from the front when the shelf container is stopped at a lower position , and the shelf device. The refrigerator provided is provided.
[0009]
[Means for Solving the Problems]
The invention of claim 1 includes a fixed rail, which is disposed at a predetermined height position of the housing part side walls, and a movable rail for moving the fixed rail in the horizontal direction, the movable rail and the times at shaft support provided on one end portion A front arm that is pivotally supported, a rear arm that is pivotally supported by the movable rail at a pivotal support provided at one end, and an action provided at the other end of each of the front and rear arms A shelf support that is pivotally attached at a point and connects between the front arm and the rear arm on both sides, and a shelf container placed on the shelf support, the shelf container being positioned behind the storage portion by the movable rail Between the front position and the front position, and by moving the front arm and the rear arm, it is possible to move up and down between the front position and the lower position, and the shelf container is in the lower position. The forearm shaft support and the shelf A straight line connecting the front end of the container with a crossing angle of 10 degrees or more downward with respect to a straight line connecting the pivot point of the front arm and the operating point of the front arm, and the pivot point of the rear arm A straight line connecting the front end portion of the shelf container is arranged with an intersecting angle of 10 degrees or more downward with respect to a straight line connecting the axial support portion of the rear arm and the action point of the rear arm, and the shelf container The bottom surface is inclined upward toward the front.
[0011]
According to the configuration of the present invention, when a strong impact is received from the front when the shelf container is stopped at the lower position , the shelf container rises upward, specifically, the front part of the shelf container. Then, the load directly received by the shaft portion can be released in the upward direction, so that the load applied to the support shaft portion can be suppressed and breakage can be prevented.
[0012]
The invention of claim 2 is characterized in that the front end surface of the shelf container has an arc shape, and when receiving an impact from the front, the front surface portion 6a of the shelf container 6 has an arc shape. When it collides with the door pocket 13 or the beat portion 12a, the force can be applied so that the front end of the shelf container 6 is directed upward, and the impact is absorbed by a curved surface. And the damage to the door pocket 13 or the beat portion 12a can be prevented.
[0013]
The invention of claim 3 is characterized in that the shelf device is arranged on the uppermost shelf of the refrigerator, and in particular, in the refrigerator, the user forgets to return the shelf container to the original position. When the door is closed, it is predicted that the shelf container and the door will collide with each other. Therefore, by suppressing the load on the shaft that occurs in such a case, the shelf device can be prevented from being damaged, and the reliability of the refrigerator can be improved. Can be held.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a perspective view showing the uppermost part of the refrigerating room 2 disposed in the upper part of the refrigerator main body 1. This refrigerating room and a storage room such as a freezing room (not shown) are provided inside the outer box via a heat insulating material. The inner box is formed.
[0015]
The refrigerator compartment 2 is arranged at the uppermost part of the refrigerator compartment body 1 in the same manner as in the prior art, and has a configuration in which cool air generated by a cooler (not shown) provided on the back side is introduced into the room by a fan and cooled. The storage shelf 5 is divided into a plurality of storage units to form a storage space for refrigerated food.
[0016]
6 is a shelf container installed over the entire width of the uppermost part in the refrigerator compartment 2, and slides in the fixed rail 7 horizontally disposed over the left and right side walls of the inner box 4 in the depth direction. The details are supported by the front arm 9 and the rear arm 10 shown in FIG. 5, which are pivotally supported on the base surface of the movable rail 8, and the shelf support 11 shown in FIG.
[0017]
Hereinafter, the descent means for moving the shelf container 6 back and forth and up and down will be described in detail. As shown in FIG. 3, which is a state in which the shelf mechanism portion is viewed from the inside of FIG. 2, the fixed rail 7 is disposed at a predetermined height position above the refrigerator compartment 2 in the depth direction, The depth of the container 6 is about half of the depth dimension of the refrigerator compartment 2 because the inner pocket portion 13 of the door 12 at the front opening of the refrigerator compartment protrudes to the indoor side due to the recent increase in storage capacity when the door is closed. Is set.
[0018]
As shown in FIG. 4, in the fixed rail 7 having a U-shaped cross section, a movable rail 8 that slides in the horizontal direction is provided by two pulleys 8a (see FIG. 14) attached to the outer upper side. The arm 9 and the rear arm 10 are separated from each other on the lower inner side of the base surface of the movable rail 8, and the lower portions thereof are pivotally supported so as to be pivotable. The rack supports 11 are held so as to be movable in parallel with the rotation of the front and rear arms by being pivotally attached at 9a and 10a.
[0019]
As shown in FIG. 6, the action points 9a and 10 are located about 15 degrees behind the vertical upper portions of the shaft support portions 9b and 10b, and when they are turned forward, they are once raised and then turned downward. Yes.
[0020]
As can be understood from FIG. 7 showing the disassembled state of each shelf functional component, between the shelf supports 11 located on the both side walls of the refrigerator compartment, the details will be described later, but slightly tilted upward toward the front. The shelf holder 15 having the shelf mounting surface is fixed by screws, and the shelf container 6 is stored by the reinforcing frame 16 made of metal wire fixed to the shelf support 11 together with the shelf holder 15 and arranged in a frame shape in the front. Form a placement section, place the shelf container 6, move on the fixed rail 7 in the front-rear direction, and maintain a substantially horizontal state by the front and rear arms 9, 10 and, strictly speaking, tilted upward toward the front It is arranged so that it can rotate up and down.
[0021]
On the upper part of the movable rail 8, the rotation of the front and rear arms 9, 10 is controlled, and when the movable rail 8 moves to the front position of the fixed rail 7, the front and rear arms 9, 10 are allowed to rotate. The stopper 17 is pivotally supported rotatably by moving the shelf support 11 together with the front and rear arms so that the shelf container 6 placed on the shelf support and the shelf support 15 can move downward.
[0022]
As a result of the rotation of the stopper 17, as shown in FIG. 9, which is a perspective view of the shelf container 6 in the forward descending state, and FIG. 1, which is a side view thereof, the protruding portion 17 c And the horizontal movement of the movable rail 8 to the rear is prevented so that the shelf container 6 does not slide directly backward from the lower position. This is also in order to prevent contact with food on shelves located behind when similarly to the above shelf container 6 moves backward directly from the lower position.
[0023]
Although the protrusion 17c acts as described above, the provision of the pulley 17d at the protrusion allows smooth sliding when contacting the upper surface of the fixed rail 7.
[0024]
As shown in FIG. 5 and FIG. 10 which is an assembly drawing thereof, a spiral spring 20 is attached to the shaft support portion 10 b of the rear arm 10. The spiral spring 20 is obtained by spirally winding a leaf spring. The slit 19a provided on the support shaft 19 is used to lock the center portion thereof, and the end portion 20a on the outer periphery of the spring is used as a flange portion for lowering the rear arm. By screwing to 10c, the direction which returns with respect to the rotation of the rear arm 10 to the front, ie, the rear arm, is urged to rotate upward and backward.
[0025]
The spiral spring 20 suppresses the descending speed due to the weight of the shelf container mechanism when the user rotates the shelf container 6 forward and downward, and conversely with respect to the shelf container 6 when raised to the rear upper part. It acts to reduce the load for lifting by applying a lifting force.
[0026]
In this example, as a result of a questionnaire survey on the giving force for raising and lowering operations for general women, the allowable giving force for lowering is set to about 30 N in a no-load state where food is not placed on a shelf, The ascending force is adjusted so as to be an allowable value of about 30 N in a state where a load of 3 kg which is a normal maximum loading amount is placed. Therefore, when a normal load is placed , Within the allowable value of 30N or less.
[0027]
Also, if you are placed over 1kg groceries is configured to fix at a lower position without giving applying force downwardly. For this reason, food can be taken in and out with both hands, and convenience is improved.
[0028]
The spring can be used as a normal coil spring. However, the spiral spring 20 can be used as a coil spring even if the rear arm 10 rotates about 110 to 115 degrees from the upper rear part to the front lowering part. The metal springs do not rub against each other and cause wear or noise.
[0029]
A spring cover 21 that covers the spiral spring 20 shown in FIG. 7 is attached to the inside of the front and rear arms 9, 10 to which the spiral spring 20 is attached. The spring cover 21 covers the spiral spring 20 that will be exposed to the outer surface when the shelf container 6 is moved downward and an oil damper, which will be described later, to improve the outer surface design, and the user holds his / her fingers between the spring portion and the like. It protects against accidental damage.
[0030]
The shelf support 11 for connecting and fixing the front and rear arms 9 and 10 is provided on the inner surface side through the spring cover 21. As described above, the shelf support 15 is fixed between the lower surfaces of both sides of the shelf support 11 with screws. In addition, the reinforcing frame 16 is fastened together, and the lower rear ends of the rear arms 10 on both sides are connected by a rear frame 22 as shown in FIG. A storage holding portion for the container 6 is formed.
[0031]
The shelf container 6 is disposed between the shelf support mechanism portions in the above state, the lower edge of the front end is fitted into the reinforcing frame 16, the bottom surface is supported by the shelf receiver 15, and the upper edge portion is supported by the shelf fixture 23. 11 is detachably locked to the upper surface of the body. As shown in FIGS. 7 and 12, the shelf fixture 23 is a through-hole formed by attaching a shaft 23a to a support portion 11a formed in a notch at the upper end of the shelf support 11 and drilled below the support portion. The upper peripheral edge of the shelf container 6 is locked and held by a locking projection 23b that engages with 11b.
[0032]
As shown in FIG. 13, in the state where the shelf container 6 is pulled out and lowered, the straight line connecting the lower position of the front end of the shelf container 6 and the action points 9a and 10a of the front and rear arms 9 and 10 is With respect to each straight line connecting the pivot points 9b, 10b and each action point, they are arranged with crossing angles A and B of 10 degrees or more downward.
[0033]
With this arrangement, for example, when the shelf container 6 on which a load of about 10 kg is placed is in the lower position and the handle is lifted in the direction of the arrow with the handle at the front end, Only the front side is lifted and the back does not rise, and the situation in which the stopper cannot be moved backward by the contact of the protrusion 17c of the stopper with the fixed rail 7 can be avoided, and the upward biasing force of the spiral spring 20 can be avoided. In addition, the shelf container 6 can be raised smoothly with a relatively light force.
[0034]
Of course, as the crossing angles A and B are larger and the positions of the action points 10a and 10b of the front and rear arms are more forward, the lifting effect becomes larger. However, the shelf container 6 is improved by extending forward and expanding the width dimension. A storage volume is also required, and as a result of the experiment, it was confirmed that it was effective if it was at the above angle or more.
[0035]
As shown in FIG. 1, the bottom surface of the shelf container 6 is provided with a predetermined angle, for example, an inclination angle C of 2 ° to 6 ° with respect to the horizontal line at the bottom end of the bottom surface. If the door pocket 13 or the beat portion 12a collides with the front surface portion 6a of the shelf container 6 when the door 12 is closed at the lower position of the shelf container 6 or at a stop position in the middle thereof, the front surface portion 6a is It rises in the direction of the arrow. Moreover, if the predetermined angle is an inclination of about 3 degrees to 6 degrees, the food item does not slide out to the back side in the cabinet due to the friction between the placed food and the placing surface, and the user's appearance There is no sense of tilting. Furthermore, since the front of the shelf container 6 is inclined, when the shelf container 6 is moved downward, it is possible to prevent the placed food product from jumping forward.
[0036]
The front surface portion 6a of the shelf container 6 has an arc shape. This is because when the shelf container 6 collides with the door pocket 13 or the beat portion 12a, the shelf container 6 receives an impact on the curved surface, so that the impact can be absorbed and relaxed, and the front end of the shelf container 6 is more upward. A force can be applied so that the door is directed, and damage to the door pocket 13 or the beat portion 12a can be prevented.
[0037]
On the other hand, an oil damper 25 is fixed to the outer surface side of the rear arm 10 as a buffer for stopping the lowering of the shelf container 6, and when the shelf container 6 after moving forward reaches the maximum lowered position, FIG. As shown in FIGS. 14 and 1 showing the state of 12 viewed from the outside, as the rear arm 10 rotates, the rubber bush at the tip of the oil damper 25 flexibly contacts the upper end of the movable arm 8 and rotates. Like to stop.
[0038]
The oil damper 25 is a cylinder in which oil is sealed. However, the oil damper 25 may be an air damper and reduces the impact and impact sound when the shelf container 6 is stopped.
[0039]
As is clear from the above-described configuration, in this embodiment, the rack mechanism units such as the front and rear arms 9, 10, the rack support 11, the rack holder 15, and the stopper 17 are fulcrums and functions with respect to the fixed rail 7 and movable rail 8. In consideration of the point and rotation-related mechanism portion, not only when the shelf container 6 is in the normal rear position, but also when the shelf container 6 is moved downward to the front, the shelf container 6 in the lower projection space at the normal rear position. The mechanism does not protrude downward from the bottom. With this configuration, even when the shelf container 6 is moved downward, the shelf mechanism portion hardly protrudes downward, and thus does not adversely affect the food placed on the shelf below or touch it down. .
[0040]
The shelf mechanism part configured as described above is arranged by inserting the movable rail 8 portion into the U-shaped structure of the fixed rail 7 from the front, and then the front opening of the fixed rail 7 is set to the front stopper 7a. It is arrange | positioned in the refrigerator compartment 2 by sealing with.
[0041]
Next, the operation of the present invention will be described. When the normal shelf container 6 is placed in the closed state in the refrigerator compartment 2 (the state shown in FIG. 2), the movable rail 8 is at the innermost part in the fixed rail 7, and the front and rear arms 9, 10 are also raised. In the installed state, it is located at the rear part of the movable rail 8, and the shelf container 6 is located and held at the rear position of the uppermost stage in the room.
[0042]
When the shelf container 6 is moved downward for storing the food 26 or taking out the placed food, if the user grips the front end of the shelf container 6 and pulls it forward, the movable rail 8 is fixed to the fixed rail 7 by the pulley 8a. It slides in and moves forward by about 2/3 of the depth dimension while being supported by the pulley 8a (state of FIG. 8).
[0043]
In this state, the arc-shaped stopper 17 attached to the movable rail 8 is prevented from rotating because the protrusion 17c is located on the upper surface of the fixed rail 7, and the guide pin 18 can move in the link groove 17a. Therefore, the rear arm 10 does not rotate and the shelf container 6 does not move downward.
[0044]
When the movable rail 8 reaches the front position and the protrusion 17c of the stopper 17 is disengaged from the front end of the fixed rail 7, the front arm 9 and the rear arm 10 can be rotated together with the rotation of the stopper 17. At this time, the guide pin 18 fixed to the rear arm 10 is in the horizontal portion of the link groove 17a, and the action point of the arm initially works upward with respect to the forward pulling force. Therefore, since the shelf container 6 has moved forward, the storage item 26 may be stored and taken out in this state.
[0045]
In order to further improve the storage workability, when the shelf container is moved forward and downward, the front end edge of the shelf container 6 is continuously held and pulled down obliquely downward.
[0046]
As described above, with the rotation of the stopper 17, the front arm 9 and the rear arm 10 can be rotated downward, and the arms 9, 10 rotate downward with the shaft support portions 9b, 10b as fulcrums, By the shelf support 11 that connects and engages the respective action points 9a and 10a, the shelf support 11 and the shelf container 6 on the shelf support 15 are lowered to the front of the refrigerator main body opening one shelf below while maintaining the horizontal state. (State of FIG. 9).
[0047]
At this time, the shelf container 6 and the shelf holding mechanism have a considerable weight including the weight of the loaded food, but can be lowered with an appropriate load force by the upward biasing force of the spiral spring 20.
[0048]
In the middle of the lowering, the protrusion 17c of the stopper 17 is locked to the front end edge of the fixed rail 7 by the rotation of the guide pin 18 by the rear arm 10, and the user should hold the shelf container 6 in the back by any chance. Even if it is pushed to the side, it does not move backward due to the stopper action.
[0049]
When the shelf container 6 is further lowered, the rubber bush at the tip of the oil damper 25 fixed to the rear arm 10 comes into contact with the upper surface of the movable rail 8 moving forward, and absorbs the impact and generates noise. Without this, the shelf container 6 is prevented from further descending and held in place.
[0050]
When returning the shelf container 6 in the lower position to the front position , if the front end of the shelf container 6 is gripped and lifted obliquely upward in reverse to the lowering operation, the pivot point and action point of each arm 9, 10 described above, Further, the shelf container 6 can be raised only by applying a light force due to the relational dimension with the front end portion of the shelf container 6 and the biasing force of the spiral spring 20. In the middle of the ascent, the protrusion of the stopper 17 is engaged with the front end of the fixed rail 7, so that the movable rail 8 can be raised without being pushed inward, and the food placed on the lower shelf by the backward movement There is no such thing as contact.
[0051]
When the shelf container 6 is raised, the engagement between the projecting portion 17c and the fixed rail 7 is disengaged, so that the movable rail 8 can be slid backward, and the shelf container 6 can be stored in a predetermined rear position by being pushed in. .
[0052]
In the above and when the shelf container 6 is pulled out, a plurality of shelf mechanism parts are combined, and each has a movable structure. In this embodiment, as described above, the rear frame 22 connects the lower rear ends of the left and right rear arms 10 that are directly related to the holding of the shelf container 6 in the present embodiment. For this reason, it is possible to suppress the quick movement of the entire mechanism section as an assembly, and to perform a smooth movement action.
[0053]
On the other hand, even when the user closes the shelf container 6 and closes the door 12 as shown in FIG. 9, the front surface portion 6a of the shelf container 6 is inclined upward by a predetermined angle C. When colliding with the pocket 13 or the beat portion 12a, a force acts so that the front end of the shelf container 6 is directed upward. Therefore, compared with the case where the shelf container is not inclined, the load applied to the shaft support portions 9a and 10a of the arms 9 and 10 can be reduced, so that the shelf life of the shelf device can be kept high, The reliability of the refrigerator using this shelf device can be increased.
[0054]
In addition, since the front surface portion 6a of the shelf container 6 has an arc shape, it is possible to exert a force so that the front end of the shelf container 6 is directed upward when it collides with the door pocket 13 or the beat portion 12a. At the same time, by receiving the impact at the time of collision with a curved surface, the impact can be absorbed and relaxed, and damage to the door pocket 13 or the beat portion 12a can be prevented.
[0055]
In the above embodiment, when the configuration of the present invention is adopted as a shelf device in a household refrigerator, not only the shelf container is provided over the entire width of the refrigerator compartment, but also one or more of the refrigerator compartment over the width direction. You may classify | divide with a partition plate, attach the said shelf apparatus with respect to each, and you may enable it to move a shelf container up and down.
[0056]
In addition, although the said embodiment demonstrated by the example employ | adopted as the mounting shelf in a refrigerator, this invention is not limited to this, A general container, a sliding shelf of tableware, a kitchen storage apparatus, a warehouse, etc. Of course, it may be adopted as a shelf configuration. Further, the shelf container is not a container shape but may be a flat shelf similar to the mounting shelf in the lower side, and the adoption position may not be the uppermost stage.
[0058]
【The invention's effect】
Even when a strong impact is applied from the front when the shelf container is in the lower position , a shelf device that suppresses a load applied to the shaft support portion and a refrigerator including the shelf device can be obtained.
