Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hold ramp, and more particularly to a hold ramp that is installed from one deck to a lower deck in a ship's hold to form a ramp for automobiles.

A hypothetical deck called a car deck that is suspended from the upper deck inside the ship's hold is stored on the lower surface of the upper deck when not in use, and the lamp inside the hold that is attached to this virtual deck is also stored on the lower surface of the upper deck when not in use. Stored. Previous devices for raising and lowering this type of inboard ramp between storage and use positions consisted of winding wires attached to each end of the inboard ramp adjacent to the temporary deck and opposite end. to take 2
A stand-alone jigger winch is installed on the underside of the upper deck. When raising and lowering this lamp in the hold between the storage position and the use position, in order to synchronize the operation of the two winches, it is necessary to control the amount of oil distributed to each winch and to detect the horizontal position of the lamp. Not only does it require a lot of manipulation, which makes handling troublesome, but it also increases manufacturing costs. The present invention aims to solve this type of problem that occurs with previous devices for raising and lowering cargo lamps.

The purpose of this invention is to provide a lamp with an economical lifting device that has a simple structure and can significantly reduce manufacturing costs to raise and lower the lamp between the storage position on the underside of the upper deck and the usage position suspended in the hold. It's about getting.

The above object of the present invention is to provide stoppers 3A and 3B installed in the middle of the height, and vertical tracks 6A and 6B installed on the upper part of the stoppers, and to install the vertical tracks 6A and 6B separately at predetermined intervals in a hold. a pair of struts 2A, 2B, and a carriage 4A, 4B equipped with horizontal arms 7A, 7B that are mounted on the track of each strut so as to be able to rise and fall and extend perpendicularly to a plane defined by both struts, respectively; A pair of horizontal arms 7A, 7B
a lamp plate 1 consisting of a rectangular flat plate disposed between the two, having a rotating shaft supported at both ends by the carriage attached to one side, and a locking protrusion that engages with each horizontal arm attached to the side edge, and the lamp plate; This is achieved by the interior lamp of the present invention, which is equipped with a winch 11 that pulls upward a wire 12, one end of which is tied to a predetermined point on the lamp plate on the opposite side of the rotation axis with respect to the center of gravity of the lamp. be done.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a conventional device 20 for raising and lowering the cargo ramp 25. The device 20 moves the cargo ramp 25 from the operating position installed between the car deck 30 and the lower deck 27 to the same level as the car deck 30. It is configured such that it can be raised to a storage position facing the lower surface of the upper deck 26 through an intermediate position placed on the upper deck 26, and conversely can be lowered from the storage position to an intermediate position and then to a use position. The lifting device 20 includes a pair of supports 2A and 2B that are installed adjacent to the left end of the car deck 30 and spaced apart from each other by a predetermined distance. Each strut 2A, 2B is provided with a stopper 3A, 3B installed at a predetermined height, and a track 6 is provided above each stopper.
It is equipped with A and 6B. Trucks or carriages 4A and 4B can be moved up and down, respectively, onto tracks 6A and 6B.
The vehicle is equipped with wheels 5A and 5B that are mounted on the vehicle and roll along these tracks. Rectangular flat lamp 2
5 has a rotating shaft 8 attached to its right end, both ends of which are rotatably supported by the carriages 4A, 4B. A wire 23 with one end connected to a position adjacent to the left end of the lamp board 25 is guided upward to pulleys 28A and 28B attached to the lower surface of the upper deck 26.
to the first jigger winch 21, to which the opposite end is connected. Another wire 24 with one end connected to the right end of the lamp board 25 is guided upward to pulleys 28C and 28D on the lower surface of the upper deck 26.
to a second jigger winch 22 to which the opposite end is connected. The first jigger winch 21 tilts the lamp plate 25 from the inclined use position to the horizontal intermediate position and further raises it to the retracted position, while the second jigger winch 22 moves the lamp plate 25 between the intermediate position and the retracted position. It is exclusively used for lifting and lowering. In the conventional device 20, two jigger winches 21 and 22 must be operated in synchrony to raise and lower the lamp plate 25 between the storage position and the intermediate position. As mentioned above, the cost of manufacturing the lamp increases due to the installation of two winches 21 and 22 and the provision of a control mechanism for synchronizing the operation of both winches.

Figures 2, 3 and 4 show the device 10 of the present invention, including struts 2A, 2B, stoppers 3A, 3B,
The configurations of the orbits 6A, 6B and the rotation axis 8 are the same as in FIG. 1. In the device 10 of the present invention, each carriage 4A, 4B has a horizontal arm 7A, 7B of a predetermined length extending toward the end opposite to the rotation axis 8 of the lamp plate 1 placed in a horizontal position. We are prepared. As shown in FIG. 4, a pair of horizontal shafts 7A, 7
B is placed on both sides of the lamp plate 1 to hold it in place, and is provided with protrusions 13A and 13B at positions facing the side edge portions of the lamp plate 1, respectively. Further, the side edge portions of the lamp plate 1 are provided with the protrusions 13A and 13B.
It is provided with locking protrusions 9A and 9B that engage with each of the locking projections 9A and 9B. As shown in FIG. 3, when the lamp plate 1 is in the horizontal position, the locking protrusion 9A engages with the lower surface of the protrusion 13A on the horizontal arm 7A, but when the lamp plate 1 is tilted (dotted chain line position) The locking projection 9A separates from the projection 13A of the horizontal arm 7A.

As shown in FIG. 2, a wire 12 with one end connected to a predetermined point M adjacent to the left end of the lamp board 1 is led upward and hung from pulleys 14A and 14B attached to the lower surface of the upper deck 26. It is led to a jigger winch 11 and the opposite end is connected to it. The device 10 of the present invention uses only one winch 11 installed at the upper left end of the lamp plate 1 to not only tilt the lamp plate 1 between the use position and the intermediate position, but also tilt the lamp plate 1 between the use position and the intermediate position. It can be raised and lowered between a storage position and an intermediate position.

As shown above, according to the present invention, the conventional winch dedicated to raising and lowering the interior lamp is omitted, and a single winch can be used to not only tilt the lamp plate but also to raise and lower it in a horizontal state. The manufacturing cost of the interior lamp can be significantly reduced.
Another advantage of the present invention is that the means adopted to omit the winch for lifting and lowering is extremely simple and can be implemented at low cost.
