Description

Movable heat-insulation storage

The present invention relates to a movable and movable heat-insulating storage.

First, the whole cold rolling box (cold roll box) as a portable heat insulation storage will be described. The cold rolling box storage body 1 is composed of a heat insulating box 2 and a machine room 3 on the upper side of the heat insulating box 2. The heat insulating box 2 is composed of an inner box 6 made of stainless steel or the like, an outer box 7 made of stainless steel or the like, and a heat insulating material 8 made of foamed urethane or the like injected between the inner box 6 and the outer box 7. The heat-insulating box 2 thus constructed has a storage chamber 10 formed therein and an opening formed in one surface thereof. In the specification, the side where the opening is formed is set as a front side. The front opening of the heat insulating box 2 is closed openably and closably by a front door 12 which is a pair of right and left heat insulating doors. A condenser, a blower for the condenser, a compressor, and the like, which are not shown, are provided in the machine room 3 above the storage body 1, and a pipe (not shown) as an evaporator is provided on the inner surface of the inner box 6, thereby constituting a refrigerator.

A cold storage material 14 is disposed on the inner surface of the storage chamber 10, and the cold storage material 14 is cooled by a refrigerator. The cool storage material 14 which becomes a low temperature is used to cool the storage chamber 10. The four corners of the lower side of the storage body 1 are provided with movable wheels 16, 17 which can freely rotate, the pair of front and rear wheels 16 on the right side are caster wheels, and the other wheels are mounted so as to be rotatable in the horizontal direction with the vertical rotation shaft as an axis, so that the direction of the wheels can be changed. On the other hand, the left front and rear wheels 17 are fixed wheels, which are not provided with vertical rotation shafts, that is, are fixed so that the direction of the wheels cannot be changed.

And recesses 21 are formed on both sides of the left and right side surfaces of the heat-insulating box 2. Each concave portion 21 is provided with a carrying handle 22, and when the cold rolling box is manually moved, the handle 22 is held by hand and a pushing force or a pulling force is applied to the cold rolling box to move the cold rolling box.

And in distribution centers, food factories, etc., the power supply line 24 of the cold rolling box is connected to a power supply. Then, the refrigerator in the machine chamber 3 operates to cool the cold storage material 14. When the cooling of the cool storage material 14 is completed, the commercial products and the like are stored in the storage chamber 10, and the power supply line 24 is removed from the power supply. In addition, in a state where the storage chamber 10 is cooled by the cold storage material 14, the cold rolling box can be moved to another place, for example, a loading/unloading place from a sorting work place. Further, the cold rolling box may be loaded on a truck or the like, and the product may be transported while being cooled or kept cold.

However, the cold rolling box may be moved by a pulling device such as a tractor, and a connecting pin for connecting the cold rolling box to the tractor may be provided. Next, this connecting pin will be described.

The bottom of the outer box 7 is formed by a base 31 having a substantially rectangular shape when viewed from above, and an end of the base 31 is substantially erected over the entire periphery thereof to form an erected portion 32. The lower end portions of the side plates 34 of the outer box 7 are fixed to the inner or outer surfaces of the right and left and rear upright portions 32 of the base 31, and the lower end of the door frame 36 of the front door 12 is fixed to the front upright portion 32 of the base 31.

A coupling pin 38 as a coupling portion is attached to a substantially central lower surface of the right end of the base 31, and the coupling pin 38 projects downward from the lower surface of the base 31. The coupling member of the tractor is detachably engaged with the coupling pin 38. And the connecting member of the tractor is connected to the connecting pin 38, the cold rolling box can be pulled by the tractor and moved.

And the cold rolling box is provided with a connecting device for connecting with the adjacent cold rolling box. This connection device is explained below. The connecting device is composed of a connecting rod R and a locking projection P engaged with the connecting rod R.

First, the connecting rod R is explained.

The connecting rod R has a substantially V-shape, and is provided with hinge portions 41 at both ends of an end portion on the mounting side, respectively, and stop members 42 for restricting the rotation of the connecting rod R with respect to the hinge portions 41 are formed at both ends of the connecting rod R. On the other hand, an engagement hole 43 as an engagement portion is formed at the top of the end portion on the connection portion side of the connection rod R. The hinge portion 41 of the connecting rod R is attached to the right end of the base 31, and a pair of attaching recesses 44 are formed in the base 31. The connecting pin 38 is disposed substantially at the midpoint between the pair of mounting recesses 44.

The right side surface, i.e., the outer side surface and the lower surface of the mounting recess 44 are opened, and the hinge portion 41 of the connecting rod R is fitted into the mounting recess 44 and locked by a screw. The rotation shaft 41a of the hinge portion 41 is substantially horizontal and extends in the front-rear direction. In this way, the end portion of the connecting rod R on the attachment side is provided on the base 31 via the hinge portion 41 so as to be vertically rotatable, and is further rotatable between a storage rotational position disposed along the right side surface of the heat insulating box 2 and a protruding rotational position at which the stop member 42 of the connecting rod R abuts against the hinge portion 41. In this accommodating pivotal position, the coupling rod R extends substantially in the vertical direction, and when the coupling rod R is pivoted by about 95 ° from the accommodating pivotal position, the coupling rod R becomes a projecting pivotal position, and has an angle of about horizontal, more specifically, about 5 ° downward with respect to the horizontal line, and further, the tip portion of the coupling rod R on the coupling portion side is slightly inclined downward with respect to the attachment portion side of the coupling rod R. And the link R is not rotatable in the horizontal direction with respect to the base 31.

The coupling rod R at the accommodating pivotal position is held on the right side surface of the heat insulation box 2 by the holding member 51. The holding member 51 is attached to the right side surface of the heat insulating box 2 by a rivet or the like, and is constituted by a guide member 53 and a slide member 54 which is guided by the guide member 53 and slides, and guide portions 53a of the guide member 53 are formed in left and right side portions, respectively, and the guide portions 53a extend in the vertical direction, and form a guide space with the heat insulating box 2. In the space introduced here, both end pieces 54a of the slide member 54 are fitted so that the slide member 54 can move in the vertical direction along the side surface of the heat insulating box 2. The center of the slide member 54 is formed in a box shape having a lower side and an opening on the heat insulating box 2 side. The slide member 54 is movable between a coupling rod holding position where the slide member 54 slides downward as shown in fig. 4a so that the lower opening of the slide member 54 is fitted into the end portion on the coupling portion side, which is the front end portion of the coupling rod R, to be engaged with the front end portion of the coupling rod R, and a release position where the slide member slides upward as shown in fig. 4b so as to release the engagement with the front end portion of the coupling rod R. A circular opening 56 having a diameter of about 20mm is formed in the outer surface of the slide member 54. The slide member 54 can be slid by being hooked with a finger to the opening 56 as a hooking portion.

Next, the locking protrusion P will be described.

The locking projection P serving as the locking portion is attached to the left end of the base 31, i.e., the side opposite to the side where the link R is provided. A recess 61 for the locking projection P is formed substantially at the center of the left end of the base 31. The left side surface, i.e., the outer side surface and the lower surface of the recess 61 for the locking projection P are open, and the mounting member 63 for the locking projection P is mounted on the lower surface of the base 31 by a screw or the like with respect to the recess 61 for the locking projection P. The center portion of the mounting member 63 of the locking projection P is recessed downward from both end portions thereof, a locking projection P mounting space is formed between the recess 61 for the locking projection P and the mounting member 63 of the locking projection P, and the locking projection P is fixed to the upper surface of the mounting member 63 so as to project upward.

The falling-off prevention member 71 is swingably attached to the lower surface of the recess 61 for the locking projection P. The swing shaft of the drop-off prevention member 71 is located on the inner side (right side in fig. 12) above the locking projection P. The falling-off prevention member 71 includes: a handle 72 bent in an * shape for operating the falling off prevention member 71, a pair of mounting members for swingably supporting the handle 72, and a falling off prevention portion 74 provided to hang down from the handle 72. A handle mounting hole 73a is formed in the pair of mounting members 73 for inserting the handle 72 into this handle mounting hole 73 a. The mounting member 73 is fixed to the lower surface of the recess 61 for the locking projection P by a screw or the like. In this way, the falling-off prevention member 71 is swingably attached to the base 31, and the central portion of the handle 72, which is the swing shaft of the falling-off prevention member 71, extends in the substantially front-rear direction and the substantially horizontal direction of the heat-insulating box 2. The drop-off preventing portion 74 as a hanging portion is formed in a substantially rectangular plate shape, and is fixed to the handle 72 by welding, bonding, or the like at an upper end portion of an outer side surface of the drop-off preventing portion 74, and the drop-off preventing portion 74 of the drop-off preventing member 71 is swingable in the left-right direction, i.e., the inward-outward direction, about the handle 72. The shake-able range of the fall-off prevention member 71 is between a position where the lower end of the fall-off prevention portion 74 abuts on the locking projection P and a position where the fall-off prevention portion 74 abuts on the base 31. In the slip-off prevention position shown by the solid line in fig. 12, the coupling rod R engaged with the locking protrusion P is prevented from being disengaged from the locking protrusion P, while in the release allowing position shown by the two-dot dashed line in fig. 12, the coupling rod R is allowed to be disengaged from the locking protrusion P.

In order to prevent damage to the side plates 34 of the outer box 7, the heat insulator 8 inside the heat insulating box 2, and the like when an article collides with the storage main body 1, each of the four corners of the storage main body 1 is reinforced by a reinforcing plate 81, and aluminum bumpers 83 and 84 are attached along the peripheral edges of the upper end portion (i.e., the upper portion of the machine room 3) and the lower end portion (i.e., the lower portion of the heat insulating box 2) of the storage main body 1. The protruding amount of the bumpers 83 and 84 is substantially the same as or larger than the protruding amount of the link R to be housed. The bumpers 83 and 84 are provided substantially all around the storage body 1, and the lower bumper 84 is not provided at the attachment points of the connecting rod R and the locking projection P.

As shown in fig. 4a, when the cold rolling box configured as described above is connected to an adjacent cold rolling box, the connecting rod R held at the accommodating rotational position needs to be rotated to the projecting rotational position via the slide member 54. Therefore, the slide member 54 at the coupling rod holding position is slid upward and moved to the release position, and the engagement between the slide member 54 and the coupling rod R is released. Then, the link R is rotated to the projecting rotational position, and the state shown by the two-dot chain line in fig. 12 is achieved. In fig. 10 and 12, the cold rolling boxes are moved closer to each other, the tip ends of the connecting rods R are brought into contact with the falling-off prevention portions 74 of the falling-off prevention members 71, the cold rolling boxes are moved closer to each other, and the falling-off prevention portions 74 are pushed into the inside, that is, the inner side, by the tip ends of the connecting rods R, whereby the falling-off prevention members 71 are rotated counterclockwise in fig. 12. The engaging hole 43 of the connecting rod R is fitted into and engaged with the engaging protrusion P. When the engagement is performed, the tip of the link R moves to the lower side without abutting against the fall-off prevention member 71. Then, the drop-off prevention member 71 rotates clockwise by its own weight to be the drop-off prevention position shown in fig. 10c, and the lower end of the drop-off prevention portion 74 of the drop-off prevention member 71 faces the upper surface of the distal end portion of the link R, thereby preventing the link R from moving upward. This connects the cold rolling boxes to each other. As described above, the connecting pin 38 connecting the tractor to the first cold-rolled tank can pull the connected cold-rolled tanks at once.

When the connected cold rolling box is to be separated, the drop-off preventing member 71 is turned counterclockwise in fig. 12 in the release direction by the handle 72 to be a release allowing position, and then the engaging hole 43 of the connecting rod R and the engaging protrusion P are released by lifting the connecting rod R. Then, the link R is rotated to the accommodating rotational position, the slide member 54 of the holding member 51 slides downward, and the link R is held at the accommodating rotational position by the slide member 54.

As described above, in the present embodiment, the caster, the connecting pin and the connecting rod as the connecting member are provided on either the right side or the left side of the storage main body 1, and the fixed wheel and the falling-off prevention member as the locking member are provided on the other side of the right side or the left side of the storage main body 1. Therefore, the direction can be smoothly changed by the caster when the cold rolling box is pulled. The rear part of the cold rolling box is not shaken to the left and right of the advancing direction by the fixed wheel, so the cold rolling box can walk in a stable state.

Since the hinge portion 41 of the coupling rod R is attached to the attachment recess 44 formed in the base 31, it does not protrude below the storage body 1, and therefore, when the coupling member of the tractor is coupled to the coupling pin 38, the hinge portion 41 of the coupling rod R does not get out of the way.

The protruding amount of the connecting rod R at the storage pivot position is smaller than the protruding amounts of the bumpers 83 and 84, and even if the cold roll box is tightly attached to the inner surface of the cargo compartment of the truck, the connecting rod R does not abut on the inner surface of the cargo compartment. Therefore, the bumpers 83 and 84 can prevent the inner surface of the cargo compartment from pressing the heat insulator via the connecting rod R and the side wall of the outer box 7. As a result, the impact force from the outside is less likely to be applied to the heat insulating material 8 by the connecting rod R or the like, and damage to the heat insulating material 8 is reduced.

As shown in fig. 11b, the upper outer side (left side in fig. 11) of the falling-off prevention portion 74 of the falling-off prevention member 71 is fixed to a handle as a swing shaft of the falling-off prevention member 71. In other words, the separation preventing portion 74 extends in the tangential direction of the swing shaft of the separation preventing member 71. Therefore, when an external force is applied to the separation preventing member 71 by the balance between the weight G of the separation preventing portion 74 and the weight of the handle 72, the lower end is inclined outward. As a result, the connecting rod R fitted to the locking projection P moves upward, and the falling off prevention member 71 biased upward from the connecting rod R rotates clockwise. Then, the lower end of the drop-off prevention portion 74 abuts against the locking projection P, rotation of the drop-off prevention member 71 is prevented, and the connecting rod R is prevented from moving upward, so that the connecting rod R does not come off from the locking projection P.

In fig. 11a, the upper end surface of the drop-off prevention portion 74 is fixed to a handle 74 as a swing shaft. In other words, the falling-off prevention portion 74 extends in the radial direction with respect to the swing shaft of the falling-off prevention member 71. Then, the weight G of the falling-off preventive portion 74 and the weight of the handle 72 are balanced, so that the lower end is inclined inward when an external force is applied to the falling-off preventive member 71. Therefore, when the connecting rod R fitted to the locking protrusion P is about to move up and down, the falling-off prevention member 71 biased upward from the connecting rod R rotates in the counterclockwise direction, i.e., the release direction. Thus, since the falling-off prevention member 71 is rotated in the release direction, the connecting rod R is allowed to move upward, and the connecting rod R is disengaged from the locking protrusion P.

In the embodiment, since the opening 56 as the hooking portion is provided in the sliding member 54, the operator can slide the sliding member 54 easily even with a military glove. And because the hooking part is formed by the opening, the hooking part does not protrude to the outside, and the collision from external articles and the like is reduced. As a result, the sliding member 54 reduces the impact applied from the outside to the heat insulation box 2.

While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention as defined in the claims.

(1) In the embodiment, the opening formed in the heat insulating box 2 is formed in the front surface, but the opening may be formed in the front surface and the rear surface of the heat insulating box 2.

(2) In the embodiment, the portable heat-insulating storage is a cold rolling box, but may be a portable warm storage.

(3) In the embodiment, the slide member 54 slides in the vertical direction, but if it slides along the side surface of the heat insulation box 2, the direction thereof can be changed as appropriate. For example, it may be moved in the lateral direction. However, when the slide member 54 is moved downward and the coupling rod R is held at the accommodating rotational position, even if vertical vibration is applied to the cold rolling box, the slide member 54 is prevented from moving upward by its own weight, and the holding state can be reliably maintained.

(4) In the embodiment, the hooking portion of the slide member 54 is constituted by the opening 56, but may be constituted by a recess and a projection. However, if the opening is formed, the protrusion does not protrude, and therefore the opening does not interfere with the vehicle.

(5) In the embodiment, the handle 72 of the fall-off prevention member 71 includes: the operation portion and the swing shaft are formed of one member as a function of the operation portion for operating the drop-off prevention member 71 and as a function of the swing shaft for swinging the drop-off prevention member 71, but the swing shaft and the operation portion may be formed of different members.

(6) In the embodiment, the caster is provided on one of the right side and the left side of the cold rolling box, but the caster may be a caster that can be switched to a fixed wheel.

(7) In the embodiment, the hinge portion 41 is provided in the connecting rod R, but if the connecting rod R is rotatably attached to the heat insulating box 2, the structure of the hinge mechanism can be appropriately changed.

(8) In the embodiment, the engaging portion of the connecting rod R is the engaging hole 43, and the locking portion that locks the connecting rod R is constituted by the locking protrusion P. For example. The engaging portion may be a projection and the engaging portion may be a hole. However, it is preferable that the engaging portion of the connecting rod P is an engaging hole and there is no protruding portion in the connecting rod R, so that the collision of the article with the connecting rod R can be reduced.

(9) In the embodiment, the rocking shaft of the drop-off preventing member 71 is rotatably attached to the heat-insulating box body 2, and the drop-off preventing portion 74 is fixedly attached to the rocking shaft, but the rocking shaft of the drop-off preventing member 71 may be fixedly attached to the heat-insulating box body 2, and the drop-off preventing portion 74 may be rotatably attached to the rocking shaft.

According to the present invention, since the coupling rod is rotatably attached to either the left side or the right side of the storage body and the locking portion is attached to the other side of the left side or the right side of the storage body, the movable heat-insulated storages are connected to each other by engaging the coupling rod with the locking portion of the adjacent movable heat-insulated storage. If the movable heat-insulating storage rooms are connected with each other in this way, a plurality of movable heat-insulating storage rooms can be pulled at a time, thereby improving the moving efficiency. And the heat insulation door is connected to the left or right side toward the heat insulation door, so that the opening of the heat insulation door is not hindered even if the movable heat insulation storages are connected to each other. As a result, the commodities in the movable heat-insulating storage can be taken out or accommodated without releasing the connecting rod, thereby improving the efficiency of the taking out and accommodating operations of the commodities.

And the connecting rod can rotate between a receiving rotating position along the side surface of the storage body and a protruding rotating position protruding from the storage body, so when the movable heat-insulation storages are not connected, the connecting rod is positioned at the receiving rotating position and can be received, thereby reducing the obstruction of the connecting rod. When an article collides with the link at the storage pivot position, the heat insulating material of the storage main body is damaged by the impact applied thereto via the link, and the heat insulating effect is remarkably reduced. In particular, since the bumper is provided at the upper portion of the storage body, when the portable heat-insulating storage is mounted on a truck or the like, even if the storage body is shaken in the left and right direction due to the shake of the truck or the like, the collision of the adjacent portable heat-insulating storage or the like with the link at the storage pivot position can be reduced.

In addition, the connecting rod and the locking part are mounted on the base of the outer box. Therefore, although a substantially horizontal force is often applied to the connecting rod when the adjacent portable heat-insulating storages are connected to each other, if the connecting rod is attached to the base as described above, the substantially horizontal force applied by the connecting rod can be dispersed throughout the entire base arranged substantially horizontally, and thus the force can be prevented from being applied to the heat-insulating material arranged on the base, and the heat-insulating material can be prevented from being damaged. In addition, because the periphery of the base on which the connecting rod is mounted is provided with a standing part, the side plate of the outer box can be conveniently fixed on the standing part.

Further, if the slide member holding the link at the receiving and rotating position is attached to be slidable along the side surface of the heat insulating box, the slide member as the member holding the link is slid along the side surface of the storage main body, so that it is possible to reduce a large projection to the outside. Therefore, the collision of the article or the like against the slide member is reduced. As a result, the impact applied to the heat insulating box can be reduced by the slide member, and damage to the heat insulating material of the heat insulating box can be prevented. And the damage of the adjacent movable heat insulation storage caused by the member for holding the connecting rod can be reduced.

Further, when the side surface of the drop-off prevention member outside the upper end portion of the drop-off portion is attached to the swing shaft, the drop-off portion is inclined outward toward the lower side due to its own weight. Therefore, even if the connecting rod is applied to the hanging part from the lower side in order to move to the upper side, the hanging part is rarely moved to the inner side, and the locking between the connecting rod and the locking part can be prevented from being released.
