Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a mobile hoisting and cooling container for a truck box type cargo box that can be installed on a truck box type cargo box and can accurately respond to loads that require temperature control of frozen foods.

[0002]

[Prior art]

 Conventionally, this kind of thing is as follows. Only fixed curtains were hung on the inside of each door of the truck bed.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. 1) It is difficult for the worker to pass through the curtain when the operator holds the luggage. 2) When the load is small, the temperature inside the cargo bed changes greatly due to the reduction of the cold storage (and heat storage) effect of the load itself. 3) The worker is working in the temperature control range and is exposed to a low temperature (or high temperature) work environment.

The present application has been made in view of such problems of the conventional technique, and an object of the present application is to provide the following things. 1) A method in which a radio wave transmitter carried by a worker is used to detect the hoisting operation, and when it approaches, it hoists and when it separates, it lowers. 2) By moving the entire winding curtain in the front-back direction, the temperature control volume is increased or decreased to facilitate temperature control. 3) Work outside the temperature control range is reduced, and the work environment can be improved.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the case of the present application, the left and right rails 3 and 4 are attached in the front-rear direction above the inner surfaces of the left and right side walls 2B of the box-shaped platform of the truck, and the left and right rails 3 and 4 are moved back and forth by a manually operated motor 10. A movable moving hardware 5, 6 is provided, and a winding curtain drum 7 that rotates in the front-rear direction is automatically supported by a motor 8 that is automatically or manually operated. The winding curtain drum 7 is made of transparent vinyl. A sheet 9A cut into a predetermined width, and a cooling curtain 9 formed by hanging a suitable number of single cooling curtains 9C configured by mounting round bar-shaped weights 9B at the lower end of the sheet 9A in a parallel state are attached. It is a mobile hoisting cooler carten for truck box type cargo bed. Further, in this case, the operation of the motor 8 senses the radio wave oscillation carried by the worker, and when approaching, the winding curtain drum 7 rotates in the winding direction of the cold insulation curtain 9, and when it goes away, the winding curtain drum 7 is moved. The cold insulation curtain 9 can be configured to rotate in the downward direction.

【Example】

 Examples will be described with reference to the drawings. Reference numeral 1 is a mobile hoisting and cooling curtain for the truck box type cargo bed of the present invention. Reference numeral 2 is a well-known truck box-shaped carrier, which comprises a floor surface 2A, left and right side walls 2B, a front wall 2C, a ceiling 2D, and a door portion 2E. Reference numerals 3 and 4 denote left and right rails attached in the front-rear direction above the inner surfaces of the left and right side walls 2B. Numerals 5 and 6 are left and right moving metal parts which are mounted on left and right rails so as to be movable back and forth. A winding curtain drum 7 is rotatably supported between these moving metal parts 5 and 6. Wheels 5A and 6A project outward from these moving hardware and roll inside the left and right rails 3 and 4.

The winding curtain drum 7 is moved by a motor 10 that is manually operated. A motor 8 for rotating the winding curtain drum 7 is connected to the left end of the left and right ends of the winding curtain drum 7. A sheet 9A made by cutting a transparent vinyl into a predetermined width and a round bar-shaped weight 9B at the lower end of the sheet 9A are attached to the winding curtain drum 7 and an appropriate number of cooling curtain single bodies 9C are hung in parallel. The cold insulation curtain 9 is attached.

As a result, by rotating the winding curtain drum 7 by the operation of the motor 8, the cold insulation curtain 9 can be lowered to the vicinity of the floor surface 2A or can be wound around the winding curtain drum 7 and raised. . In this case, the motor 8 can be operated by manually operating the switch.

Further, the operation of the motor 8 detects radio wave oscillation from a transmitter carried by an operator, and when approaching, the winding curtain drum 7 rotates in the winding direction of the cold insulation curtain, and when the motor 8 is separated, the winding curtain drum 7 rotates. The drum 7 can be configured to rotate in the downward direction of the cold insulation curtain. In this case, the radio wave is transmitted from the transmitter (not shown) carried by the operator via the receiver 11 attached to the side wall 2B of the box-shaped carrier 2.

Reference numeral 12 is a well-known right tail lamp portion, and an automatic manual changeover switch 12A and a manual switch 12B are provided in this portion. Referring to FIG. 6, both ends of the motor 10 are connected to the wire 13A stretched in an endless shape of the pulley 13 arranged at the upper four corners of the box-shaped carrier 2 and the left and right moving hardware 5, 6 are connected. Are connected. This proposal can also be used for buildings that require temperature control (factory, warehouse, etc.).

The operation will be described. 1) Move the entire cold insulation curtain back and forth according to the amount of cargo to increase or decrease the temperature control range. 2) The operation of rolling up the cold insulation curtain senses the radio wave oscillation from the transmitter carried by the worker, and rolls up when approaching and descends when leaving. Of course, it can be done manually.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. 1) Since the temperature control range can be increased or decreased, temperature control becomes easier and at the same time the temperature control cost is reduced. 2) Since the entire cold insulation curtain is moved back and forth by a manually operated motor, it is possible to maintain cargo and ensure worker safety. 3) In the operation of rolling up the cold insulation curtain, the operator senses the radio wave oscillation from the transmitter, and when it approaches, it rolls up, and when it separates, it lowers it. You can load and unload luggage without leaving it.
