Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a handrail for a ship, and more particularly to an automatic tilting handrail for a movable deck.

2. Description of the Related Art Conventionally, handrails have been provided around the decks of ships for safety.However, when the decks are not in use, these are installed on the upper part of the deck below the hull fixing part. A movable deck that can be stored in is also known. However, in such a movable deck, the handrails installed around the movable deck interfere with the storage of the deck, so it is necessary to remove it from the deck before storing the deck. Become. For this reason, as a handrail for such a movable deck, it is generally performed so that it can be attached to and detached from the deck.

An example of this type of conventional detachable handrail will now be described with reference to the drawing as shown in FIG. 10 of the accompanying drawings.

That is, FIG. 10 shows one kind of handrail of this kind. This handrail has several handrail post sockets 1 arranged around the deck D at predetermined intervals. And the number of detachable handrail posts 2 corresponding to the handrail post socket 1, each detachable handrail post 2 being
At its lower end, it is detachably attached vertically to each of the handrail post sockets 1 installed on the deck 1 by appropriate means. In addition, a rope receiver 3 having a circular cross section is fixedly attached to each of the detachable handrail columns 2 at a predetermined height in several stages, and each of the detachable handrail columns 2 corresponds thereto. A handrail is formed by arranging the handrail rope 4 in the rope receiver 3 of height, for example. Then, the moving deck D having the handrail having such a configuration is
When it is stored in the upper part, the movable deck D can be stored for the first time after removing each removable handrail post 2 from the respective handrail post socket 1 in advance. On the contrary, when the movable deck D in the retracted state is lowered and installed at a predetermined position, each detachable handrail post 2 is provided for the handrail post installed on the deck D after the installation. By mounting it on the socket 1, it is necessary to place the handrail. However, since the attachment / detachment of the detachable handrail post 2 must be performed manually, the work is very complicated and time-consuming.

For this reason, an automatic tilting handrail has already been proposed in order to automatically perform the complicated and time-consuming work required for attaching and detaching the handrail post 2 in a short time.

Now, a typical example is shown in FIG. That is, in this handrail, each handrail post 5 is attached to the deck D at the lower end thereof so that it cannot be turned outside the hull but is turnable inside the hull, and several adjacent handrail posts 5 are provided. For each, this handrail pillar 5
At a position directly above the ship, a tilting link 6 is rotatably attached to the fixed part of the hull at the upper end, and a handrail post 5 is rotatably attached to the lower end of the tilting link 6 at its upper end. I am doing it. In this way,
Every few handrail pillars 5 are connected to the fixed part of the hull via the hoisting link 6, so that each handrail pillar 5
Will be maintained upright.

Then, when the movable deck D having the handrail having such a structure is raised to the upper storage position represented by the chain line as D'in FIG. In the handrail post 5 rotatably connected to the pedestal, since the tilting link 6 gyrates in the direction of the arrow Z about the rotatably connecting portion of the upper end portion of the handrail pillar 5 to the fixed portion of the hull, At the lower end, it turns with respect to the deck D, and is housed under the fixed part of the hull together with the raising / lowering link 6 as shown by the chain line in the figure. The handrail pillars 5 are connected to each other via the handrail 7,
Other railing posts will also be stowed at the same time. Further, when lowering the deck D'in the retracted state to the position of the deck D in the lower set position, it is obvious that the handrail is set upright again.

Compared to the handrails described earlier, this automatic tilting handrail simplifies the work and reduces the work time because the work is performed automatically when the moving deck is stored or installed in the set position. There is a certain thing that can be shortened. However, in this automatic tilting handrail, the moving deck D has the lowest set position (D),
It cannot be used for a movable deck whose height is adjustable, which is set and installed at an intermediate position between the storage position (D ').

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, the conventionally known manually attachable / detachable handrail requires attachment / detachment work when it is used as a moving deck, when the deck is stored and when it is installed at the set position. Similarly, there is also a problem that a conventionally known automatic tilting handrail cannot be used for a height-adjustable moving deck that is set to an intermediate position. is there.

In view of the above, the present invention finds out that the above-mentioned problems in the conventionally known ones are solved, solves the problems in the conventionally known ones, and the height can be adjusted. The object is to obtain an automatic tilting handrail that can be used for a moving deck.

Means for Solving the Problem The present invention is characterized in that, in order to solve the problem, the handrail can be automatically raised and lowered by utilizing the elevating operation of a movable deck.

In the handrail for use, a handrail (50) has an end handrail post (10) and an adjacent end handrail post (10) whose lower end portions are rotatably connected to each other on the moving deck (D).
It consists of several intermediate handrail posts (11) placed between the two, and the end handrail post (10) has a moving deck (D) when the moving deck (D) is in the lowest set position. ), An upper link (23) whose upper end is pivotally connected to a fixed part of the hull, an intermediate link (25) whose upper end is pivotally connected to its lower end, and its lower end. And the lower link (21) that receives the movable body relative to each other form a lower link (21) of the handrail upright link (20) that is arranged in a substantially vertical state. ) Is the moving deck (D) at the bottom set position
Is initially movable relative to the intermediate link (25) during the ascending to the retracted position after passing through the intermediate set position. It is characterized by an automatic tilting handrail in which the upper link (23) is pushed up integrally with the (25) and is swung with respect to the fixed portion of the hull.

Furthermore, the link body 25 ₀ intermediate portion link 25 is inserted between the plate member 21 ₀ of opposed lower link 21, from its upper end, are extended a certain dimension downward, the body 25 ₀ On the outer surface of the lower end of the
A pair of plate-like spacers 25 ₁ having a certain thickness are fixed so as to face each other, and these spacers 25 ₁ enable the intermediate link 25 to smoothly slide inside the lower link 21. Has been done. Incidentally, the spacing between the plate member 21 ₀ pair constituting the lower link 21, the portion below the spacer 25 _first portion secured to the lower end of the intermediate portion link 25, the plate members 21 ₀ It is closed by the plate member 21 ₁ of the pair which is secured to the adjacent outer edges of the. Further, in the lower portion of the lower link 21, on the inner surface of the plate members 21 _0, plate-shaped stopper 27 for pushing up the middle portion link 25 is secured horizontally. Further, on the inner surface of each plate member 21 ₀ of the lower link 21, the body 25 ₀ of the stopper 28 of a pair in close proximity to the anchored spacer 25 ₁ in the lower part of the intermediate portion link 25 is fixed horizontally , when the lower link 21 is relatively raised with respect to the intermediate portion link 25, a stopper 25 that these stopper 28 secured to the lower link 21, is secured to the lower end portion of the link body 25 ₀ intermediate portion link 25 It comes in contact with the upper end of ₁ .

The automatic tilting handrail according to the present invention has the above-mentioned structure, and its operation will be described below.

When the movable deck D is set at the lowermost position as shown in FIGS. 1 to 5, the upper link 23, the intermediate link 25 and the lower link forming the handrail tilting link 20 are formed.
21 is a link connecting pin 22 that connects the upper link 23 to the upper fixed-side eye plate 30, and the main body 23 _{0 of the} upper link 23.
A lower link member 23 ₂ fixed to the link body 25 ₀ of a middle link 25 is pivotally connected to a link connecting pin 24 and a lower link 21 which are pivotable to an eye plate 16 fixed to a moving deck D. The center of each of the link connecting pins 17 connected to each other is placed on the same vertical center line XX, and the lower link 21 has its lower end portion on the moving deck D. Is connected to the eye plate 16 on the side through the link connecting pin 17, and the upper end is connected to the intermediate link.
By being connected to the upper fixed eye plate 30 via the link connecting pin 22 via the 25 and the upper link 23, this state can be firmly maintained. In this state, since the lower end of the end handrail post 10 or the lower link 21 is prevented from turning to the outside of the hull with respect to the moving deck D, the handrail 50
Will be installed safely.

Further, the intermediate handrail post 11 whose lower end portions are rotatably connected to the deck via the eye plate 15 also has the lower links 21 constituting the handrail upright link 20 via the handrails 13, that is, By being connected to the end handrail post 10, it is firmly maintained on the moving deck D.

When the moving deck D in the state of being set to the lowermost position is moved to a predetermined intermediate set position above it, as shown in FIGS. 6 and 7, as the moving deck D moves, The link 21 is guided by the intermediate link 25 and relatively rises.
When the stopper 27 for pushing up the intermediate link, which is fixed to the inside of the lower link of the intermediate link 21, hits the lower end of the intermediate link 25, the lower link 21 and the intermediate link
The relative movement with respect to 25 has stopped, and this state is also the position where the moving deck D has been raised to the intermediate set position D '(see FIGS. 6 and 7). Further, in this state, the handrail 50 is also raised to the intermediate position so that it can be easily analogized from FIG. 1, but in this case as well, the lower link 21 or the end handrail post 10, the intermediate handrail post is made. Since the handrail 11 and the handrail 13 are maintained in the original state with respect to the moving deck D ', the handrail 50 is reliably maintained even in this intermediate rising set position of the moving deck D'. .

Then, the movable deck D ', as shown by chain lines in the fourth and fifth figures, when to the raised to its stowed position D ", the intermediate portion link 25, the lower end of the link body 25 _0, lower Since the link 21 is in contact with the intermediate link pushing-up stopper 27, the intermediate link 25 and the lower link 21 simultaneously rise as the moving deck D ′ rises. A stopper 26 fixed to 25 for restricting the folding direction of the intermediate link 25 and the upper link 23 hits a lower plate member 23 ₂ fixed to the lower end of the main body 23 ₀ of the upper link 23. Therefore (see FIGS. 8 and 9), in the upper link 23, the center of the bent portion of the lower plate member 23 ₂ fixed to the lower end of the link body 23 ₀ is
Due to the fact that it is inside the hull rather than the vertical center line XX, which is the straight line connecting the centers of the link connecting pins 22, 24 above and below it, around the link connecting pin 22, an arrow is shown in FIG. It is turned in the direction indicated by X, and finally becomes the state shown by the chain line in the figure, and accordingly, the movable deck D ″ reaches the retracted state and the intermediate link 25 and the lower link 21
Similarly, as shown by the chain line in the figure, it also assumes a substantially horizontal state. In this case, it is obvious that each intermediate handrail post 11 also lies in the same plane as the lower link 21 by being connected to the lower link 21 via the handrail 13.

In this way, when the movable deck D is in the retracted state (D ″), the movable deck D ″ is surely held by the appropriate means on the fixed portion of the hull, and therefore the handrail 50 is also
It will be secured safely.

On the contrary, when the movable deck D ″ in the retracted state is installed at the intermediate set position or the lowest set position, the procedure is reversed according to the reverse procedure for retracting to the upper set position. It is clear that you will be told.

Effect of the Invention Since the present invention has the above-described structure and operation, when it is used as a handrail for a moving deck,
The handrail can be automatically tilted in accordance with the movement of the moving deck, and the moving deck is set not only at the re-lower limit set position but also at the lowest lower limit set position,
Even at an intermediate set position between the upper upper part and the retracted position, since it can be automatically and surely installed, even if compared to the conventionally known one-stage automatic tilting handrail, its effect is great. It's clear.
