[Technical field to which the invention belongs]

 In this invention, the connection between the rear unloading part of the container provided in the truck that transports frozen goods, refrigerated goods, heat insulation goods, etc. excluding products stored at room temperature and the cargo handling frontage of the warehouse is cut off from the outside air The present invention relates to a dock shelter comprising a pair of left and right side pads disposed on both left and right sides of the cargo handling frontage and a head pad disposed between upper portions of the pair of left and right side pads.

[0002]

[Prior art]

 The dock shelter shown in FIGS. 4 and 5 is generally used. It is composed of a pair of left and right side pads 20, 20 fixed to the left and right sides of the cargo handling frontage 1 of the warehouse, and a head pad 21 disposed above these side pads 20, 20. By connecting the rear unloading part 6A of the container 6 provided in the truck 5 and the cargo handling frontage 1 of the warehouse with these members 20, 20, 21 in a state of being shut off from the outside air, the inside of the warehouse is opened. In order to prevent air from leaking to the outside and to prevent outside air from entering the warehouse, it is necessary to keep the warehouse at a predetermined temperature and to prevent insects and dust from entering from outside. I have. In some cases, the height of the container of the truck varies depending on the truck. Conventionally, the head pad 21 is configured to be vertically movable, so that the vertical position of the head pad 21 is adjusted according to the height of the container. I can do it. As shown in FIG. 4, the head pad 21 is moved up and down by wire ropes 23 and 24 having one end connected to the left and right ends on the back side of the head pad 21, and the other end of the wire ropes 23 and 24. Is connected to a weight balance counterweight 28 via three pulleys 25, 26, and 27, so that the head pad 21 can be held at an arbitrary vertical position. The head pad 21 can be lowered by pulling down the lowering operation rope 29 hanging down from the head pad 21, and the ascending operation rope 30 hanging down from the counter weight 28 can be pulled down. By pulling downward, the head pad 21 can be raised. In FIG. 4, reference numeral 22 denotes a bottom pad, and reference numeral 31 denotes a guide rail for guiding the head pad 21 so as to be movable up and down. Has been established.

[0003]

[Problems to be solved by the invention]

 According to the above configuration, since the large and heavy head pad 21 must be moved up and down, there is a disadvantage that the entire dock shelter becomes a large-scale device. Further, the head pad 21 is made of an elastic material so as to be able to absorb the impact force when the rear end of the truck container comes into contact with the head pad 21 that cannot move in the front-rear direction. Depending on the size of the head pad 21, the head pad 21 may be deformed and become unusable. In order to avoid deformation of the head pad 21, an iron plate 32, which is a metal plate, is attached to the rear surface (rear surface) of the head pad 21 as shown in FIG. Although the deformation of the head pad 21 is avoided by using the iron plate 32, the weight of the iron plate 32 is increased and the dock shelter is not only enlarged, but also the iron plate 32 on the rear surface of the head pad 21 which is lowered. When unloading or loading workers accidentally hit the head, or the mast of a forklift was mistakenly brought into contact with the vehicle, injuries occurred or the head pad 21 was damaged. In addition, troubles such as the dropping of the head pad 21 and the falling of the counterweight 28 occurred. Also, when the head pad 21 is lowered, the head pad 21 cannot move up and down due to the pressing force from the container of the truck. Therefore, the position of the head pad 21 with respect to the container is changed again. In such a case, the truck must be moved, and the work of adjusting the head pad 21 up and down is troublesome.

[0004] In view of the above situation, the present invention seeks to solve the problem by not only avoiding the increase in the size of the device, and being advantageous in terms of safety, but also adjusting the hanging of the hanging curtain according to the height of the container. Another object of the present invention is to provide a dock shelter that can easily and quickly perform the above-mentioned steps.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention shuts off the open air between the rear unloading part of the container provided on the truck that transports frozen goods, refrigerated goods, heat insulation goods, etc. and the cargo handling frontage of the warehouse. A dock shelter comprising a pair of left and right side pads arranged on both left and right sides of the cargo handling frontage to connect in a state, and a head pad arranged between upper portions of the pair of left and right side pads, A hanging curtain is mounted on the upper surface of the head pad and configured to descend through a through hole formed in the head pad. Therefore, the hanging curtain can be adjusted to the height of the truck container by being guided by the through holes and descending. Even if the trailing end of the container of the truck comes into contact with the hanging curtain, the hanging force can be moved backward to absorb the impact force caused by the contact. In addition, since the hanging pad does not move up and down, the hanging curtain moves up and down, so that not only can the head pad and the mast of the forklift be hard to reach, but also the head pad can be positioned. By using a soft material, it is possible to avoid the occurrence of troubles such as injury to the operator, damage to the mast of the forklift, or damage to the head pad even if the contact is made. . Further, even if the head of the worker or the mast of the forklift comes in contact with the hanging curtain, there is no occurrence of trouble such as injury to the worker, damage to the mast of the forklift, or damage to the head pad as described above. . Further, the vertical position of the hanging curtain can be adjusted without moving the truck positioned at a predetermined position for unloading (loading).

A curtain roll capable of winding the hanging curtain is mounted on an upper surface of the head pad, and the hanging curtain can be moved up and down by rotating the curtain roll. That is, by rotating the curtain roll in one direction, it can be raised by winding up the unwound curtain roll, and by rotating the curtain roll in the opposite direction to the above-mentioned direction, the wound curtain roll can be rotated. It can be lowered by feeding out. The configuration in which the curtain roll is operated by a manual force is advantageous in cost.

The head pad includes a first elastic body located outside and a second elastic body disposed inside the first elastic body and having a softer property than the first elastic body. By doing so, the impact force coming into contact with the head pad can be reliably absorbed in two stages.

[0008]

[Embodiment of the invention]

 FIG. 1 and FIG. 2 show a dock shelter of a hanging curtain movable type. This dock shelter is distributed over a pair of left and right side pads 2 and 2 disposed on the left and right sides of a cargo handling frontage 1 formed in the warehouse shown in FIG. The provided head pad 3 and the hanging curtain M are main constituent members. By means of the four members 2, 2, 3 and M, the space between the rear unloading section 6A of the container 6 provided on the truck 5 for transporting frozen goods, refrigerated goods, heat insulation goods and the like and the cargo handling frontage 1 of the warehouse. The connection can be made in a state of being cut off from the outside air. S shown in FIG. 3 is a shutter for closing the cargo handling frontage 1.

Like that. The head pad 3 can also be made of a soft material in the same manner as described above. However, as shown in FIGS. 2 and 3, the head pad 3 is located on the outside and is made of a soft material such as soft urethane foam or soft rubber. And a second elastic body 3 such as a sponge, which is provided inside the first elastic body 3A and has a softer property than the first elastic body 3A. By using two layers, there is an advantage that the impact force contacting the head pad 3 can be reliably absorbed in two stages.

As shown in FIGS. 1 and 2, the hanging curtain M has a curtain roll 7 that can be wound up and attached to an upper surface of a rear end (an intermediate portion or a front end) of the head pad 3. The banner M can be moved up and down by rotating the roll 7. One end of the hanging curtain M is inserted downward from above into a vertically extending through hole 3C formed on the front end side of the head pad 3, and the hanging curtain M is guided vertically through the through hole 3C. Have to be able to. As shown in FIG. 3, when the truck 5 is backed, the rear surface of the container 6 is in contact with the front surface of the banner M. Numeral 8 shown in FIG. 2 is a cover for covering the upper side of the curtain roll 7 to be wound. A cover for covering a portion of the hanging curtain M exposed on the upper surface of the head pad 3 may be attached.

The hanging curtain M is provided with a holding mechanism (not shown) that is urged toward the winding side by a coil spring (not shown) and can be held at an arbitrary pulling position where the pulling operation is performed. Accordingly, by pulling the lower end of the hanging curtain M and operating it downward, the hanging curtain M can be positioned at a predetermined lowering position, and then released from the hanging curtain M, the position can be held at the pulled position. When the hanging curtain M is to be lifted, the holding by the holding mechanism is released by pulling downward once, then raised to a predetermined position, then slightly pulled downward again from that position, and then released. Position can be held. The banner M may be moved up and down by another configuration. Here, the cost can be reduced by employing a configuration in which the banner M is moved up and down by a manual operation force.
