Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device U for a car deck.
This invention relates to a device for locking a deck at a predetermined level.

The temporary deck consists of a temporary deck that is suspended from a storage position that is secured to the underside of the deck at a predetermined height inside the hold. In order to maintain a fixed car deck at a predetermined level, the top layer of the car deck is connected from the hull deck to each car deck below the second layer.・Detsuki is an advanced car・
Previously, σ was suspended from a deck using a link of a predetermined length.
) is the first row. Each link is articulated at the center of its length 14B and is constructed so that it can be folded when the car deck is assembled together at storage position i+ on the lower deck level. . In the case of a multi-layer car deck, the links that are attached to the upper car deck are large in size with joints (I7), which increases the weight of the entire car deck and reduces manufacturing costs. Inflate. The present invention
The aim is to eliminate such problems that occur in the mechanism that keeps the deck at a predetermined level.

The object of the present invention is to provide a simple and inexpensive structure in which the car deck is automatically locked to a vertical wall such as a bulkhead or support column at a predetermined height when lowered into a hold from a storage position on the underside of the deck. The objective is to obtain a locking device manufactured in Hongji.

According to the present invention, it is preferable to provide one way at a position facing a vertical wall such as a bulkhead or a column, and an end face parallel to the vertical wall, from a storage position at the lower surface level of the deck to a storage position at the lower surface level of the deck. A locking metal fitting used for a car deck that moves up and down between a predetermined distance down and a use position, the slender pin being placed perpendicular to the end face and attached to the end face so as to be slidable in the axial direction. Place one end of the member on the car deck and the opposite end on the pin ill material, then apply a pressing force to the pin member in a direction that causes the pin member to protrude from the end face, and the car deck is completed! There is provided a locking fitting for a car deck characterized by comprising a spring member which pushes the pin member into a recess provided in the vertical wall when the fixing level is reached.

Now, to explain the embodiments of the apparatus of the present invention with reference to the drawings, the following is an explanation.

Referring to FIG.
2 car decks 21 that have descended to a predetermined level within 3

When each car deck 21 r 22 descends from the storage position 24 and reaches a predetermined level, an inventive device is used to hold each car deck 21 r 22 at its respective level. Locking device] 0 (・ro.

As shown in FIG. 3, the car decks 21 and 22 to which the locking device of the present invention] 0 is installed are placed in advance in a position facing the vertical wall 3 of the bulkhead or column, and parallel to this 2t, IQt or 2'.
It has a closing end surface 9 and has a length of 2"L.

The locking device 10 is attached to the car decks 21 and 22.

Pin member 1 made of bar material and left end pin member 1 (τ connected right 9i #j p bolt 12 pin 2 web) IB
The first spring member 2 is composed of fC and a broken spring member 2. The pin member 1 is slidably fitted into the sleeve 8 which is horizontally bent over the end surface 9 and the web IIA, and has a downward protrusion 5t on the lower surface of the left side. 'I am prepared. The spring member 2 has a coil shape and has a flange 25 attached to the right 4M.
The bolt 12 is welded to the right side of the flange 25. An adjusting nut 1 screwed into the bolt 12
3 is the left % of the web IB, ll K is placed, and the bolt 12 is locked to the right 1 dll K protruding part of the web IIB.
Nut 14 is inserted. Therefore, the adjusting nut 13
By appropriately adjusting the position of the flange 25 on the bolt 12 and then tightening the lock nut 12, the flange 25 can be placed in a desired position and the pressing force of the spring can be adjusted. Inner tube member 18 into which the left end portion of the coil spring 2 is fitted
A connects the left side 4 of the coil spring 2 by welding the left gVL. The outer tube member 18B is a coil
It is fitted into the outer side of the spring 2, the right side of which is in contact with the flange 25, and the left end of which is inserted into the outer side of the inner tube member 18A. Therefore, inner tube member] 8A
The outer member 18B forms a telescopic casing 18 that expands and contracts in sync with the coil spring 2.

The vertical wall 3 has a recess 4 at a position facing the end surface 9 of the car deck 2] and 23. It is growing. The recess 4 has several horizontal plates 6 at its lower end, a liner 7 is attached to the upper surface of the horizontal plate 6, and a pin member protrudes from the end surface 9 of the car deck 2, 22. The length l of the liner 7 is smaller than the length L of the horizontal plate 6, and the left side 11 of the liner 7,
