Further, casters 23 are provided at the four corners of the bottom surface of the bottom portion 21d. Further, as shown in FIG. 4, the cooling chamber Rc is partitioned into a front portion and a rear portion via a partition net 24, the front portion is configured as a tray storage chamber Rcf, and the rear portion is configured as a machine chamber Rcm. A blower fan 25 and a cooler (heat exchanger) 26 are disposed in Rcm. Thus, when the blower fan 25 is operated, the cold air is blown in the horizontal direction along the left wall surface Mp and the right wall surface Mq of the interior S along the path indicated by the dotted arrows Fp and Fq, and also in the vertical direction. Cool air blow along the inner wall surface is performed. In addition, other apparatus parts (not shown), such as a compressor, are arrange | positioned at the back surface of the refrigerator case 21. FIG. The tray housing chamber Rcf, which is a rectangular parallelepiped space, includes the rack device 1 according to the present embodiment.

  Next, the configuration of the rack apparatus 1 according to the present embodiment will be specifically described with reference to FIGS.

  The rack apparatus 1 includes a plurality of hook portions 3 attached to the left and right wall surfaces Mp, Mq of the inside S of the refrigerator Mc. That is, as shown in FIG. 1 (a), the hook portions 3 are attached at four locations on the front and back and top and bottom of the left wall surface Mp (left and right and top and bottom in FIG. 1 (a)). Attach to the four locations in the same way. Accordingly, the hook portions 3 are attached to the left and right total eight places. FIG. 3 shows the overall shape of the hook portion 3. As a basic configuration (shape), the hook portion 3 includes a holding portion 3s that holds the rack portion 2p or 2q, and a bolt portion 3b that is integrally formed at one end of the holding portion 3s. The hook portion 3 can be attached to a predetermined position on the left wall surface Mp or the right wall surface Mq using the bolt portion 3b.

  The hook portion 3 is provided with holding position changing means 4. In this case, as a specific configuration (shape), the holding portion 3s is formed integrally with the round rod-shaped first holding portion 3sa from which the above-described bolt portion 3b protrudes from one end and the other end of the first holding portion 3sa. A large-diameter disk-shaped first stopper portion 3ca, a second holding portion 3sb integrally formed on the tip surface of the first stopper portion 3ca, and a second stopper portion 3cb integrally formed on the tip of the second holding portion 3sb Constitute. That is, since the second holding portion 3sb and the second stopper portion 3cb have the same shape as the first holding portion 3sa and the first stopper portion 3ca, the combined shape of the first holding portion 3sa and the first stopper portion 3ca is left as it is. What is necessary is just to comprise in the shape added to the front end surface of 1st stopper part 3ca. Thereby, the specific shape of the holding part 3s having the first holding part 3sa, the first stopper part 3ca, the second holding part 3sb, and the second stopper part 3cb constitutes the holding position changing means 4, and the first holding part It functions as a plurality of holding positions Xa and Xb where the positions of 3sa and the second holding portion 3sb are different.

  Therefore, the holding position changing means 4 has a function of changing the holding position X with respect to the left wall surface Mp (right side surface Mq) of the holding portion 3s holding the rack portion 2p (2q), and in particular, this holding position. The form of the changing means 4 constitutes a holding position selection mechanism 11 that can be changed by selecting a plurality of different holding positions Xa and Xb. If such a holding position selection mechanism 11 is used as a form of the holding position changing means 4, there is an advantage that the required holding positions Xa and Xb can be changed accurately, easily and quickly.

  The rack apparatus 1 includes a pair of left and right rack portions 2p and 2q. As shown in FIGS. 1 and 4, each rack portion 2p, 2q includes six vertical frames fv arranged in the vertical direction and seven horizontal frames fh arranged in the horizontal direction with respect to the vertical frames fv. Are provided with rack body parts 2pm and 2qm which are configured symmetrically in the vertical direction. In this case, the two inner frames of the vertical frames fv... Serve as guide frames that prevent the horizontal swing of the trays Ta. The horizontal frames fh ... are formed in a U-shape in plan view, and the five horizontal frames fh ... except for the uppermost and lowermost horizontal frames fh ... support trays Ta ..., Tb ... 2ps ..., 2qs ... Therefore, the tray support portions 2ps..., 2qs... Are arranged in five stages (a plurality of stages) and can support five trays Ta (or Tb...).

  On the other hand, as shown in FIG. 1A, four latch members 5p are attached to the rack body 2pm. In this case, the respective retaining members 5p are attached to the upper position and the lower position of the vertical frames fv disposed at the front and rear ends, respectively. Specifically, the hook members 5p formed in a C shape are prepared and fixed to the vertical frames fv by welding or the like. As a result, a total of four latching portions 5p... Are respectively attached to the front and rear and upper and lower (left and right and upper and lower in FIG. 1A) positions of the rack body 2pm. It corresponds to the position of the two hook portions 3. Further, at this time, the latching members 5p are provided at a vertically asymmetric position of the rack main body 2pm. That is, as shown in FIG. 1 (a), the distance Lu between the upper end of the rack body 2pm and the upper latching member 5p, and the interval between the lower end of the rack body 2pm and the lower latching member 5p. The interval Ld is selected so that Lu> Ld. Thus, since the latching member 5p is formed in a C shape, the latching part 5pf by the upper curved part and the latching part 5ps by the lower curved part which are opposite to each other are configured. Is done. Therefore, by reversing the top and bottom of the rack body 2pm, it is possible to select the upper hooks 5pf or the lower hooks 5ps to be hooked on the hooks 3.

  Further, the rack portion 2p (rack main body portion 2pm) is provided with a reverse display portion 6m by markings indicating the top and bottom of the rack portion 2p. 1A shows a state where the rack portion 2p is held at the upper position, and FIG. 1B shows a state where the rack portion 2p is held at the lower position. In this case, when FIG. 1A is the standard position, as shown in FIG. 1A and FIG. 2, the reverse display portion 6m by marking is applied to a part or the whole of the horizontal frame fh positioned at the lowermost portion, specifically Specifically, it is colored by applying a paint using a relatively conspicuous color such as yellow or sticking a seal.

  The one rack portion 2p has been described above, but the other rack portion 2q is configured in the same manner as the one rack portion 2p. Therefore, one rack portion 2p... Is prepared, one is used as the rack portion 2p, and the other is used as the rack portion 2q. In the other rack part 2q, 2qs ... is a tray support part, 5q ... is a latching member, 5qf ... and 5qs ... are a latching part using an upper curved part in the latching member 5q ... and a lower curved part. The used latching part is shown. Moreover, each rack part 2p, 2q, and also the hook part 3 ... mentioned above can each be formed with the material which did not generate | occur | produce rust easily, or the material which performed the antirust process, specifically, a metal material or a plastic material etc. it can.

  Next, the usage method (function) of the rack apparatus 1 which concerns on this embodiment is demonstrated with reference to FIGS.

  First, the hook portions 3 are attached to the left wall surface Mp and the right side surface Mq of the inside S of the refrigerator Mc. In this case, the bolt portions 3b of the hook portions 3 are used to be attached to the four positions on the left wall surface Mp in the front and back and up and down directions (up and down and left and right in FIG. 1A), and the four positions on the right wall surface Mq. Are also installed in the same way.

  Then, a pair of rack portions 2p, 2q is prepared, and the holding members 3s of the corresponding hook portions 3 ... attached to the left wall surface Mp are attached to the respective latching members 5p ... attached to the four locations of the one rack portion 2p. The hook members 5q attached to the four positions of the other rack portion 2q may be hooked to the holding portions 3s of the corresponding hook portions 3 attached to the right wall surface Mq. As described above, the rack portions 2p and 2q can be attached to the left and right wall surfaces Mp and Mq very easily.

  At this time, the rack portions 2p and 2q can be mounted by selecting two different holding positions Xa and Xb in the holding position changing means 4 (holding position selection mechanism 11). That is, as shown in FIG. 4, when the wide trays Ta ... are accommodated in the rack accommodating chamber Rcf, each of the rack portions 2p, 2q is shown in the enlarged extraction diagram of FIG. 2 and the phantom lines in FIG. The latching portions 5pf, 5qf,... Are latched on the first holding portions 3sa. In this case, since the holding position Xa is selected, the interval between the left and right tray support portions 2ps... And 2qs. On the other hand, when the trays Tb... Having a narrow width are accommodated in the rack accommodating chamber Rcf, as shown by the enlarged extraction diagram in FIG. 2 and the solid line in FIG. 4, the latching portions 5pf of the rack portions 2p and 2q. .., 5qf are hooked on the second holding portions 3sb. In this case, since the holding position Xb is selected, the interval between the left and right tray support portions 2ps... And 2qs. In FIG. 5, an arrow Fio indicates the direction in which the trays Ta..., Tb.

  In this way, the rack device 1 is attached to the left and right wall surfaces Mp, Mq, and a plurality of hook portions 3 that hold the rack portions 2p, 2q by the holding portions 3s, and a holding portion 3s that holds the rack portions 2p, 2q. If the holding position changing means 4 that can change the holding positions X with respect to the left and right wall surfaces Mp, Mq are provided, the interval between the left and right rack portions 2p and 2q can be changed. Therefore, at least a plurality of types of trays Ta,..., Tb, having different sizes (width dimensions) can be used, and the versatility is excellent. In addition, since the holding position changing means 4 can be provided only by improving the hook portions 3 attached to the left and right wall surfaces Mp, Mq, it can be implemented very easily with a relatively simple configuration. Therefore, it is excellent in low cost, and the occupied space associated with the holding position changing means 4 is hardly expanded, so that unnecessary enlargement can be avoided. The holding position changing means 4... Increases the protruding length of the hook portions 3. As a result, the apparent dead space is widened. However, as shown by the dotted arrows Fp and Fq in FIG. Flows into the rack housing chamber Rcf along the left and right wall surfaces Mp, Mq, and the spread between the left and right wall surfaces Mp, Mq and the rack portions 2p, 2q improves the uniformity of the cooling area and further the cooling efficiency. The apparent spread of dead space is not necessarily a disadvantage.

  On the other hand, in the rack apparatus 1 according to the present embodiment, as shown in FIG. 1, when attaching the latching members 5p... 5q to the rack body 2pm, the tray support 2ps. , 2qs... Can be easily changed. That is, as shown in FIG. 1 (a), the interval Lu between the latch members 5p, 5q,... Arranged at the upper and upper positions of the rack body 2pm, and the lower and lower positions of the rack body 2pm. Since the interval Ld between the latching members 5p, 5q,... Is selected so as to satisfy the relationship Lu> Ld, when used in this state, the racks 2p, 2q are positioned at a higher position, as shown in FIG. As shown in FIG. 5, the interval Lsu between the ceiling position Xu of the rack housing chamber Rcf and the tray support portion 2ps at the uppermost portion is narrowed, and the interval Lsd between the bottom surface position Xd and the tray support portion 2ps at the lowermost portion is increased. Therefore, since the bottom tray support 2ps can be loaded from the bottom shallow tray to the bottom bottom tray Tp, it can be used as a standard height configuration.

  By the way, as shown in FIG. 1B, when the tray Tn having a shallow bottom is accommodated, a dead space is generated in the lower portion of the rack accommodating chamber Rcf at the standard height shown in FIG. End up. Therefore, in this case, the rack portions 2p and 2q shown in FIG. 1A can be turned upside down to be hooked on the hook portions 3. That is, as shown in FIG. 1B, the latching members 5p..., 5q... Arranged at the lower position are latched on the upper hooks 3. Can be hooked on the lower hooks 3. As a result, the interval Lsu between the ceiling position Xu of the rack housing chamber Rcf and the tray support portion 2ps at the uppermost portion is increased, and the interval Lsd between the bottom surface position Xd and the tray support portion 2ps at the lowermost portion is decreased. Accordingly, no dead space is generated in the lower portion of the rack storage chamber Rcf, and a wide space can be secured in the upper portion of the rack storage chamber Rcf. Therefore, the tray Tn disposed at the uppermost portion includes other trays Tn. The same thing can be put, or a high foodstuff or a big foodstuff can be carried if necessary.

  At this time, the inversion display portion 6m by marking provided on the rack main body portions 2pm, 2qm is located on the upper side and colored with a relatively conspicuous color such as yellow as shown in FIG. Therefore, the user can confirm at a glance that the rack portions 2p and 2q are inverted. That is, FIG. 1A shows the standard mode in which the reverse display portion 6m is positioned on the lower side and the rack portion 2p is held in the upper position, and FIG. 1B shows the reverse display portion 6m. .. Is positioned on the lower side, and it can be easily confirmed that the rack portion 2p is in the reverse mode for supporting the tray Tn with the shallow bottom held at the lower position, and the height position can be changed surely and smoothly. Can do.

  In addition, even when the positions of the reverse display portions 6m are different on the left and right, the state can be seen at a glance, so even if you forget to change one of the left and right rack portions 2p, 2q, The state can be confirmed, and the heights of the left and right rack portions 2p and 2q can always be matched. Therefore, when the trays Tp..., Tn... Are accommodated, there is an advantage that it is possible to surely avoid problems such as the trays Tp.

  Thus, in the rack apparatus 1 according to the present embodiment, at least two different engaging portions 5pf, 5ps,..., 5qf, which can be engaged with the hook portions 3 attached to the left and right wall surfaces Mp, Mq. , 5qs..., 5qs..., 5qf..., 5qs... Can be selected to change the heights Lsd. Since the rack portions 2p and 2q are provided, the height position of the rack portions 2p and 2q can be changed very easily and quickly. Therefore, even when a plurality of types of trays Tp..., Tn... With different depths are frequently used, the overall work efficiency can be dramatically increased. In addition, rack body portions 2pm and 2qm configured vertically symmetrically by a combination of a plurality of vertical frames fv and a plurality of horizontal frames fh are used for the rack portions 2p and 2q, and the rack body portions 2pm and 2qm are vertically asymmetric. Are provided with latching members 5p ..., 5q ... having at least two latching portions 5pf ..., 5ps ..., 5qf ..., 5qs ... in opposite directions, and the rack body portions 2pm, 2qm are turned upside down. Since the latching portions 5pf ..., 5ps ..., 5qf ..., 5qs ... of the latching members 5p ..., 5q ... can be selected, the front-rear direction (wall surface direction) position of the trays Tp ..., Tn ... is changed. And can be changed to any height position. In particular, the rack apparatus 1 according to the present embodiment is optimal for use in the storage M, particularly the illustrated cooling chamber Mc. In other words, if applied to a commercial quick cooler (blast chiller), it is possible to improve the convenience and convenience of the user in hotels, restaurants, etc. that use this type of quick cooler.
