Embodiment 1 FIG.
1-4 is a figure explaining the structure of the shelf apparatus of the refrigerator which concerns on Embodiment 1 of this invention, FIG. 5 is a figure which illustrates notionally engagement of a rotation tray and a locking member, FIG. 8 is a diagram for explaining the method of assembling the shelf device, FIGS. 9 to 13 are diagrams for explaining the operation thereof, and FIG. 14 is a diagram for explaining the case where the front and rear movable shelf shown in FIG. FIG.

  In the figure, the refrigerator shelf device is arranged in a vertical direction with respect to a rail 1 formed of a resin material having a good sliding property such as a polyacetal resin fixed symmetrically in an inner box of the refrigerator not shown. The front / rear movable shelf 2 having a shaft hole 21 that is constrained in movement and movable in the front-rear direction and penetrates in the vertical direction near the center, and a shaft hole that is rotatably provided on the upper surface of the front / rear movable shelf 2. The rotating tray 3 provided with an engaging portion 31 (FIG. 2) below the position corresponding to 21 and the engaging portion 31 of the rotating tray 3 are locked through the shaft hole 21 from the lower side of the front and rear movable shelf 2. Thus, the rotating tray 3 is composed of a locking member 4 that holds the rotating tray 3 with respect to the front and rear movable shelf 2 so as to be rotatable about the shaft hole 21.

  The front / rear movable shelf 2 is formed using a highly transparent resin material, and a front end flange 22 serving as a design component and a reinforcing structure for improving appearance in appearance is formed at the front end portion thereof. A reinforcing sheet metal can also be installed in the front end flange 22 portion. The front / back movable range of the front / rear movable shelf 2 is a side wall step of a protruding portion 1a provided on the side wall of the rail 1 installed before and after the rail 1 and a rail sliding portion 23 installed at both left and right ends of the front / rear movable shelf 2. It is regulated by the portion 23a. The engagement method between the front and rear movable shelf 2 and the rail 1 and the attachment and detachment structure of the front and rear movable shelf 2 are not particularly limited to the above examples, and conventional conventional techniques and known techniques are appropriately used. be able to.

  The rotating tray 3 is made of a highly transparent resin. Of the four surrounding sides, the two front and rear sides are straight lines parallel to each other, the two left and right sides are formed in an arc shape, the upper surface is substantially flat, and the surrounding four sides are upward. It is formed in a dish shape or a basin shape with a protruding edge 3a. The engaging portion 31 provided below the central portion of the rotating tray 3 includes a rotating shaft 31a formed of a protruding cylindrical portion, and a pair protruding symmetrically outward in the radial direction from the protruding end portion of the rotating shaft 31a. The engaging piece 31b. In this example, two notches 21a for allowing the engagement pieces 31b to pass through are provided symmetrically on the inner periphery of the shaft hole 21 at a position of 180 degrees.

  The locking member 4 is formed into a circular and thin lid shape using a resin material having good sliding properties such as polyacetal resin, nylon resin, and the like. 3) for receiving an engagement piece 31b formed with an outer diameter that can slide smoothly with respect to the inner peripheral surface of the shaft hole 21 and an inner diameter that is larger than the outer diameter of the rotary shaft 31a. An arcuate engagement body 41 having a notch 41a is projected. The projecting portion of the engaging body 41 on the outer diameter side of the base portion constitutes a flange-shaped retaining portion 42 having a diameter larger than that of the shaft hole 21. A pair of locking portions 43 that are engaged with the engaging pieces 31b by snap fitting are formed symmetrically at a position of 180 degrees on the circumference at the coupling portion between the engaging body 41 and the retaining portion 42.

  The engaging portion 43 has a recess 43a in which the engaging piece 31b of the rotating tray 3 received in the notch 41a enters in the direction of arrow B in FIG. 3, and the vicinity of the inlet 43b of the recess 43a is engaged. It is formed in a convex shape (detailed illustration omitted) for giving a predetermined resistance to the piece 31b. On the other hand, on the other surface C (FIG. 4) opposite to the rotation tray 3 of the locking member 4, a grip portion 44 for gripping at the time of engagement / disengagement with respect to the engagement portion 31 is recessed upward from the surface C side. And is formed so that the dimension in the height direction of the locking member 4 is as small as possible.

  When the rotating tray 3 is rotatably fixed to the front and rear movable shelf 2 by the locking member 4, the locking member 4 is rotated with respect to the rotating tray 3 in the direction opposite to the arrow D as shown in FIG. Thus, the engaging piece 31b of the rotating tray 3 enters the locking portion 43 relatively in the direction of arrow D and is fixed. 5A schematically shows a state before fixing, and FIG. 5B schematically shows a state where fixing is completed.

  The engaging piece 31b once locked to the locking portion 43 by the snap fit is restrained from moving in the direction of releasing the engagement by the convex shape near the inlet portion 43b of the locking portion 43. It is possible to prevent the locking member 4 from falling off due to friction or vibration during the rotating operation. Further, when the locking member 4 is removed from the rotating tray 3, the locking member 4 is rotated in a direction opposite to that when the locking member 4 is fixed with a force exceeding the binding force in the rotational direction due to the convex shape near the inlet portion 43b. Thus, the engagement between the locking portion 43 and the engagement piece 31b is easily released. For this reason, the rotating tray 3 can be attached to and removed from the front and rear movable shelf 2 with one touch, and tools and complicated work are not required. In addition, on the other surface C, as shown in FIG. 4, characters indicating the engagement / disengagement direction are engraved together with arrows.

  6 to 8 are views for explaining a process in which the rotating tray 3 is placed on the front / rear movable shelf 2 and is rotatably fixed by the locking member 4. First, as shown in FIG. 6, the rotary tray 3 is disposed above the front and rear movable shelf 2, and on the front and rear movable shelf 2 so that the rotary shaft 31 a of the rotary tray 3 enters the shaft hole 21 of the front and rear movable shelf 2. Place it in the direction of the arrow in the figure. At that time, the engaging piece 31 b is fitted so as to pass through the notch 21 a of the shaft hole 21. Next, as shown in FIG. 7, the locking member 4 is locked from the lower side of the front and rear movable shelf 2 to the engaging portion 31 of the rotating tray 3 that has entered the shaft hole 21 by snap fitting, so that the rotating tray 3 is held to the front and rear movable shelf 2 so as to be rotatable about the shaft hole 21. FIG. 8 shows a state where the rotation tray 3 has been fixed.

  As shown in FIG. 8, the locking member 4 constituting the shelf device is such that the bottom surface of the front and rear movable shelf 2 is formed only by a flange-shaped retaining portion 42 protruding downward from the lower surface of the front and rear movable shelf 2. The part is generally flat. Of course, the lower end of the locking member 4 can be positioned higher than the lower end of the front end flange 22 of the front and rear movable shelf 2 when viewed from the front of the refrigerator. It is also easy to fit the direction dimension within the thickness of the front end flange 22 of the front and rear movable shelf 2. Further, in this example, the rotating tray 3 is configured to be the same as or slightly larger than the depth dimension of the front and rear movable shelf 2 as shown in FIGS. It is not limited to. Moreover, when using the shelf apparatus of this invention for a refrigerator, it cannot be overemphasized that 1 step | paragraph may be used and multiple steps | paragraphs may be used.

  Next, the operation of the first embodiment configured as described above will be described with reference to FIGS. In addition, these figures have shown typically an example in which the shelf apparatus of Embodiment 1 was installed in the refrigerator compartment, and also the food group 5 was mounted in the rotation tray 3. FIG. FIG. 9 shows that the front and rear movable shelves 2 are pushed into the inner side of the refrigerator inner box (not shown), and the rotating tray 3 is in a normal refrigerated position where two parallel sides are located at the front and rear. A relatively tall food group 5a such as a soft drink or the like is placed on the near side, and a relatively short food 5b such as a margarine or miso container is housed in the back side of the cabinet. The state is called “original position”.

  In the state where the tall food group 5a is placed in front of the short food 5b as shown in FIG. 9, when it is desired to take out the short food 5b, as shown in FIG. If the rotating tray 3 is simply pulled out along the rail 1, the distance between the short food 5b and the user is reduced, so that the short food 5b can be easily taken out, but the short food 5b is still taken out. The tall food group 5a obstructs the route, and the tall food group 5a hides the short food 5b so that it is difficult for the user to visually recognize. In the past, the tall food group 5a is shifted left and right. Or after taking out the tall food group 5a, it was necessary to take out the short food 5b.

  In the shelf apparatus according to the first embodiment, the front / rear movable shelf 2 is free to move back and forth with respect to the rail 1, and the left and right sides of the rotating tray 3 are formed in an arc shape. The shaft hole 21 can be freely rotated around the rotation center. Therefore, in the state where the food group 5 is placed on the above-described shelf device, when the user wants to take out the food 5b having a short back on the back side, the user holds the front left end portion of the rotating tray 3 in front, for example. By pulling, the forward movement of the front / rear movable shelf 2 and the rotating tray 3 and the rotation of the rotating tray 3 counterclockwise by 90 degrees are linked, and one action is performed until the forward rotating state shown in FIG. You can move with. For this reason, the ease of taking out and the visibility of the short food 5b which has been hindered by the tall food group 5a is greatly improved.

  Next, when the shelf device is stored after the user takes out the short food 5b or places another short food 5c (FIG. 12), the shelf device shown in FIG. Of course, as shown in FIG. 12, the tall food group 5a is on the back side and the short food product 5c (5b) is on the near side as shown in FIG. After completing the rotation by 90 degrees and 180 degrees from the initial position, the front and rear movable shelf 2 can be moved as shown in FIG. For this reason, the user does not have to arrange food in consideration of the frequency and height of use, so not only the convenience as a food storage device is improved, but also the refrigerator innermost space where the expiration date tends to approach The food stored in the refrigerator can be easily refrigerated while being rearranged in the front space in the refrigerator, and the effect of reducing loss due to expiration of the food's shelf life can be achieved.

  In addition, when the rotation tray 3 is fixed by the locking member 4 at the shaft hole 21 portion of the front and rear movable shelf 2, the retaining portion 42 is restricted from moving upward by the shaft hole 21, so that the rotation tray 3 is It is seated vertically with respect to the front and rear movable shelf 2. Therefore, during the rotating operation of the shelf device, for example, as shown in FIG. 11, when the rotating tray 3 protrudes greatly from the front / rear movable shelf 2, it is caused by the fall of an object from the upper portion of the shelf device or the push-up from the lower portion of the shelf device. Even when a load is applied to the rotating tray 3, the rotating tray 3 does not come off from the front and rear movable shelf 2 or drop off. Moreover, since the grip part 44 which a user hold | grips is formed so that it may dent upward from the bottom face of the securing part 42, the height of the locking member 4 is not increased. Further, by forming the locking member 4 with a resin having good slidability, it is possible to suppress wear of the rotating shaft portion during the rotating operation of the shelf device.

  On the other hand, FIG. 14 shows an example in which the rotating tray 3 of FIG. In this case, after removing the locking member 4 and removing the rotating tray 3, the removed locking member 4 is turned upside down, and the locking member 4 inverted from the shaft hole 21 of the front and rear movable shelf 2 is mounted from above. To do. Since the front end flange 22 is provided at the front end of the front and rear movable shelf 2, the front and rear movable shelf 2 can secure rigidity as a shelf for storing food even if the rotating tray 3 is removed.

  Further, by removing the rotating tray 3, food can be placed in the four corner space portions formed on the outer sides of the left and right arc-shaped sides of the rotating tray 3, so that the effective shelf area is increased. Moreover, since the locking member 4 is attached to the shaft hole 21, it is possible to prevent liquid dripping from the shaft hole 21 to the lower side of the shelf device when the food placed on the front and rear movable shelf 2 falls. In addition, a ring-shaped packing or the like may be inserted between the peripheral edge portion of the shaft hole 21 and the locking member 4, and the shaft hole 21 and the locking member 4 may be fastened by, for example, a snap fit.

  As described above, Embodiment 1 includes a rail 1 provided symmetrically in a refrigerator inner box, and a movable front and rear shelf that is restrained from moving in the vertical direction with respect to the rail 1 and that can be moved back and forth. 2, the rotating tray 3 that is freely rotated at a shaft hole 21 portion that is one rotating shaft with respect to the front and rear movable shelf 2, and the same thickness as the front end flange 22 provided at the front end of the front and rear movable shelf 2. The locking member 4 includes a locking member 4 that is fixed to the engaging portion 31 of the rotating tray 3 with a single touch and is restrained in the vertical direction with respect to the front and rear movable shelf 2 that rotatably supports the rotating tray 3.

  According to the first embodiment configured as described above, the rotating tray 3 does not easily fall from the front and rear movable shelf 2, and thus safety can be improved. In addition, the locking member 4 has a lid shape with a large diameter and a small thickness, and is fitted and fixed to the rotating tray 3 by snap fit. Since it is possible to remove the rotating tray 3 with one touch, it is easy to attach and detach the rotating tray 3. For this reason, it is easy to clean the dust, dirt, etc. that have entered the gaps between the component parts. In addition, since the locking member 4 protrudes below the front and rear movable shelf 2 only by the thickness of the retaining portion 42, it is easy to make the overall height dimension thinner than the height dimension of the front end flange 22 part, Not only is the appearance of the shelf device clear, but also food that is high enough to be stored below the shelf device does not come into contact with the retaining portion 42 of the locking member 4 during the rotation operation, preventing the food from falling over the shelf device due to the rotation operation. it can.

  Further, since a resin material with good slidability is used as the locking member 4, wear of the rotating shaft portion is suppressed, wear powder is not generated, the inside of the refrigerator can be kept clean, and abnormal noise during rotation operation Can be prevented. Moreover, it has the effect that it can be used also as a storage shelf with a large effective shelf area only by removing the rotation tray 3 without adding components. Further, since the grip portion 44 for gripping the locking member 4 is formed in a concave shape upward from the bottom surface of the locking member 4, the locking member 4 is arranged with respect to the entire height of the shelf device. The included rotation support part does not protrude downward. For this reason, the appearance is clean and the food stored in the space below the shelf device is in contact with the food stored in the lower part of the shelf device, and the food does not fall down.

  The increase of the sliding part of the rotation tray 3 and the front-and-back movable shelf 2 is prevented, and generation | occurrence | production of the abnormal noise and wear powder during rotation operation is suppressed. Further, even when the user wants to eliminate the rotation function and expand the storage space, after removing the rotation tray 3, the front and rear movable shelf 2 has an area obtained by removing the retaining portion 42 from the projected area of the locking member 4. Since there is only a hole, sufficient strength is ensured, and by placing the locking member upside down, it has a function to prevent dripping when food falls down, and has an unprecedented remarkable effect It is.

Embodiment 2. FIG.
FIGS. 15 and 16 are perspective views for explaining a refrigerator shelf device according to Embodiment 2 of the present invention. FIG. 15 shows a case where a rotating tray is used, and FIG. This is a case where the upper and lower sides are inverted. In FIG. 15, lock levers 6 (6A, 6B) that also serve as functions for easily recognizing the completion position of the rotational movement of the design component and the rotating tray 3 are symmetrically provided at the left and right ends of the front end flange 22 of the front and rear movable shelf 2. Is provided. The lock lever 6 is formed of resin, and is installed at the front end portion of the front and rear movable shelf 2 so as to be slidable independently in the left and right directions indicated by arrows E with respect to the front and rear movable shelf 2. When both of the lock levers 6 are slid in the central direction, the lock lever 6 enters the rotation trajectory of the rotation tray 3, and the rotation tray 3 is locked in both clockwise and counterclockwise rotations.

  The front and rear movable shelf 2 is detachably engaged with a rail 1 (not shown), and is configured to be able to engage with the rail 1 even when the top and bottom are reversed and the back surface is directed upward. Has been. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  In the second embodiment configured as described above, even if a design part or a functional part such as the lock lever 6 is added to the front / rear movable shelf 2, the same effects as those of the first embodiment can be obtained. When only the front and rear movable shelf 2 is used with the rotating tray 3 removed, the front and rear movable shelf 2 can be turned upside down and the back side can be used if desired. In that case, the convex part 2b of the upper corner part on the near side of the front / rear movable shelf 2 moves to the lower side as it is turned upside down, and the four corners of the front / rear movable shelf 2 have the same effective area as in the first embodiment. Therefore, it can be widely used as a storage shelf. The lock position and lock method may be changed as appropriate.

Embodiment 3 FIG.
FIG. 17: is sectional drawing which shows the principal part of the shelf apparatus of the refrigerator which concerns on Embodiment 3 of this invention. The drawing shows a state in which the locking member 4A is locked to the engaging portion 31 of the rotating tray 3 from below the front and rear movable shelf 2 by snap fitting. In the drawing, the upper surface 4a of the grip portion 44 of the locking member 4A and the central back surface 3b of the engaging portion 31 of the rotating tray 3 are in close contact with each other. Other configurations are the same as those of the first embodiment.

  According to the third embodiment configured as described above, since the locking member 4A and the center back surface 3b of the engaging portion 31 of the rotating tray 3 are in surface contact with each other, high bending rigidity is obtained, for example, rotation Even when a concentrated load is applied in the vicinity of the center of the tray 3, it is possible to suppress the deformation and the deflection angle of the rotating shaft portion of the shelf device, and to prevent the rotation operation failure due to the deformation of the shelf device and the breakage due to insufficient strength. In general, the storage shelf of the refrigerator is subject to creep deformation due to a long-term food storage load and permanent deformation near the center of the shelf, but by attaching the locking member 4A formed as described above. The deformation of the rotating tray 3 can be corrected, and the rotation operation failure due to the deformation of the shelf device can be prevented even during long-term use. Moreover, even if a heavy stored item is placed, the deformation of the rotating tray 3 is suppressed by the upper surface 4a of the locking member 4 coming into contact with the rotating tray 3. For this reason, generation | occurrence | production of the noise and abrasion powder during rotation operation can be suppressed.

  In the first to third embodiments, the case where the outer peripheral surface of the engagement body 41 provided on the locking member 4 slides on the inner peripheral surface of the shaft hole 21 of the front and rear movable shelf 2 has been described. However, the configuration is not necessarily limited thereto, and for example, the outer peripheral surface of the rotating shaft 31 a of the rotating tray 3 may be configured to slide on the inner peripheral surface of the shaft hole 21. In that case, in order to reduce friction due to sliding, for example, a ring member (not shown) made of a resin material having good slidability such as polyacetal resin on the inner peripheral surface of the shaft hole 21 or the outer peripheral surface of the rotating shaft 31a. You may wear. In this case, the engagement structure between the locking member 4 and the engaging portion 31 of the rotating tray 3 is the same as the embodiment, for example, by providing the engaging piece 31b on the axial center side of the rotating shaft 31a. Can be obtained. Further, the engagement structure and engagement method between the engagement portion 31 and the locking member 4 are merely examples. For example, the locking member 4 is reliably prevented from falling off by using a ratchet claw or a latch mechanism at the engagement portion. It goes without saying that modifications and changes can be made as appropriate.
