Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic opening / closing roof for a small-sized or medium-sized freight vehicle such as a freight vehicle, particularly a refrigerated vehicle or a refrigerated vehicle.

[0002]

[Prior art]

 Conventionally, there has been a roof in which a top plate on both sides and side members connected to the top plate can be opened and closed like wings on both sides along an axis provided in the front-rear direction at the center of the roof.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned conventional roof is wide open to the left and right sides and opens upward, it is inconvenient to load and unload loads in a narrow space. When I was loading and unloading, I had to bend my hips, so the work efficiency was poor and it was easy to cause back pain. Also, in refrigerating vehicles, refrigeration vehicles, etc., a large amount of cold air escapes each time they are loaded and unloaded, thus reducing the refrigeration capacity. In addition, there are drawbacks such as poor waterproofness and airtightness. In view of the above problems, the present invention has made it possible to easily load and unload loads in a narrow space and to facilitate loading and unloading work in a luggage compartment with a low roof. In cold storage vehicles and refrigerated vehicles, we will reduce the loss of cold air due to the opening and closing of the roof, and also provide a roof for freight vehicles that is highly waterproof and airtight and that can be easily opened and closed. To do.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, the roof is formed of a pair of left and right roof panels that are divided into two parts at the center in the front-rear direction, and the outer ends of both roof panels are hinged to the tops of the left and right side walls of the vehicle body. The inner edge has a waterproof edge that overlaps when closed, and a cylinder is provided on the front side wall of the vehicle body.A pair of arms are attached to the upper end of the cylinder rod, and the tips of each arm are paired with the above-mentioned pair of arms. The roof panels are connected to the front and back surfaces of both roof panels so that they can be opened and closed vertically. Further, an elastic support member such as a gas damper that constantly pushes up the rear side portions of the left and right roof panels is provided on the upper rear side of both side walls.

[0005]

[Action]

 The operation of the present invention will be described. When the cylinder 17 is operated and the cylinder rod 19 is extended, the arms 21 and 22 are raised, and the left and right roof panels 5 and 6 are moved upward with the hinges 7 and 8 as fulcrums. It can be rotated to open it to the vertical state, and when the cylinder rod 19 is contracted, the roof panels 5 and 6 rotate downward and descend to the horizontal state, and the waterproof edges 13 and 14 overlap to seal the upper part of the vehicle body. To do. Thus, the gas dampers 27 and 28 act so as to push up the rear ends of the roof panels 5 and 6 at all times, so that the roof panels are smoothly twisted when opening and closing.

[0006]

【Example】

 An embodiment of the present invention will now be described with reference to the accompanying drawings. Reference numeral 1 denotes a vehicle body of a van type vehicle such as a refrigerating vehicle or a refrigerating vehicle. Reference numerals 2 and 3 denote left and right side walls of the vehicle body. Reference numerals 5 and 6 denote a pair of left and right roof panels each having a shape divided into two along the center of the roof in the front-rear direction. Outer ends 9 and 10 of the roof side walls 2 and 3 are provided by waterproof long hinges 7 and 8. The inner edges 11 and 12 are provided with waterproof edges 13 and 14 that overlap when closed. Reference numerals 15 and 16 denote waterproof rubber seals. Reference numeral 17 denotes an electric cylinder vertically provided in a central portion inside a front side wall 18 of the vehicle body 1. An arm mounting plate 20 is provided on an upper end portion of a cylinder rod 19 of the electric cylinder, and both end portions of the mounting plate 20 and the roof described above. Arms 21 and 22 are connected to the rear bases of the panels 5 and 6, respectively. Reference numerals 23 and 24 denote pivotally attached portions at both ends of the arm, and 25 denotes a guide rail of the cylinder rod 19, and a stopper 35 for stopping the cylinder rod 19 at a fixed position is provided at an upper end portion thereof. When the motor 26 of the cylinder 17 is rotated, the cylinder rod 19 and the arms 21 and 22 move up and down along the guide rails 25, and accordingly, the roof panels 5 and 6 can be opened and closed. There is. When opening and closing the roof, one arm 22 is formed slightly longer than the other arm 21 so that one roof panel 6 opens slightly ahead of the other roof panel 5 and closes with a slight delay. The waterproof edges 13 and 14 are overlapped and can be opened and closed smoothly. Further, 27 and 28 are gas dampers mounted along the vehicle body frame 29 at the rear of the left and right side walls 2 and 3 to assist the smooth opening and closing of the roof panel, and the lower end portions 30 and 31 thereof are rotated. The upper end portions 32 and 33 are pivotally attached to the rear end portions of the back surfaces of the roof panels 5 and 6 so that the rear end portions of the roof panels 5 and 6 are constantly pushed upward by elastic force. ing. Although the electric cylinder 17 is used to open and close the roof panels 5 and 6 in the above example, a hydraulic cylinder may be used instead. In the case of the electric cylinder 17, the roof panel can be stopped at any opening / closing angle. Further, instead of the gas damper 27, another elastic supporting member can be used. 34 indicates a rear door that opens and closes to the left and right.

[0007]

[Effect of device]

 According to the structure of claim 1, since the left and right roof panels can be opened and closed vertically on the left and right side walls around the hinges, unlike the conventional wing-like opening and closing, there is no protrusion on both sides. It is easy and safe to load and unload loads even in tight spaces. Further, when the roof is opened, the waist is not bent when loading and unloading the cargo in the luggage compartment, so that the work can be performed efficiently and the back pain can be prevented. Furthermore, with the roof open, heavy items and contaminated items that are difficult to handle by hand can be loaded and unloaded from above by cranes or suspension rails. Thus, in the cold storage vehicle, the freezer vehicle, etc. according to the present invention, the roof panel only rotates up and down to open and close the roof, so that the escape of cold air associated with loading and unloading work can be minimized, so the cooling capacity is There is no loss. Since the top plate according to the present invention can be easily loaded with a heat insulating material, it can be easily configured as a refrigerating vehicle or a cold storage vehicle. Furthermore, since the roof of the present invention can enhance the airtightness of the luggage compartment, it is easy to protect the luggage from rain and dust and is hygienic, and the smell is less likely to leak to the surroundings even if odorous substances are loaded. is there. With the configuration according to claim 2, there is no fear of twisting the left and right roof panels when the roof is opened and closed, and smooth operation is easy.
