Description

[Detailed Description of the Invention] The present invention relates to an improvement of a mount device for installing navigational instruments and the like on a ship.

Ship navigational instruments and electronic equipment, such as receivers, recorders,
When installing meter displays, etc. on a tabletop inside a ship, it is necessary to securely fix them in consideration of the vibrations and sway of the ship. It is normal to remove it.

Therefore, when installing these devices, there are contradictory requirements: they must be securely fixed against vibrations, and they must also be easy to remove.

Although various proposals have been made for such gantry devices, none of them fully satisfies the above requirements.

It is desirable to operate from the front, especially in a narrow ship, but it has been impossible to suppress vibrations in all directions by tightening only from the front.

The present invention solves the above-mentioned drawbacks, and aims to provide an instrument that can be attached and detached by simply operating from the front, and can be fixed without loosening in all directions, and has a simple structure and is inexpensive.

The drawings will be explained below.

Figure 1 is a side view of the device of the present invention. 1 is the housing for navigational instruments such as the receiver, recorder, meter display device, etc.; 2 and 4
2 is a fixture provided on the bottom side of the casing 1, and 2 is a fixing plate provided on the front side of the bottom side of the casing 1, in which a mounting hole 3 for a screw 8 is bored.

Further, 4 is a fixed leg provided at the rear position on the bottom side of the housing 1, and as shown in Fig. 2, it has a short neck 4' on the bottom side, and the lower part extends to both sides. It has an inclined surface portion 4''.

Reference numeral 5 designates a pedestal, as shown in Fig. 3, which is constructed by bending the front and rear sides of a metal band-shaped plate. A front fixed seat part 5' is provided, and a tapped hole 8 is provided at a position corresponding to the mounting hole 3 of this front fixed seat part 5'.
The rear part of this board is folded forward and bent down to form a rear fixed seat part 5'', and a V-shaped notch 7 is provided on the front edge side of this rear fixed seat part 5'' at a position corresponding to the fixed leg 4. It is.

This pedestal 5 is fixed to a tabletop (not shown) by an appropriate method.

In the pedestal device of the present invention having the above configuration, the casing 1 is inserted onto the pedestal 5 from the front in the direction of the arrow as shown in FIG. After that, the screws 8 are inserted into the mounting holes 3 provided in the fixing plate 2 of the casing 1, and fixed through the tapped holes 6 provided in the front portion 5' of the pedestal 5.

Note that 9 is a washer. Since the length of the neck 4' of the fixed leg 4 is shorter than the thickness of the plate material of the rear fixed seat 5'', the surface extending across both sides of the inclined surface 4'' is on the back side of the V-shaped notch 7. is pressed against both lower corners of the narrowed part at the same time, and the thick part at the back of the notch 7 is held down by the wedge action between the bottom side of the housing 1 and the inclined surface part 4'', so that the It is fixed at the same time and can be fixed extremely reliably.

Also, the gap 10 between the 5' part of the frame and the fixing plate 2 is filled with a screw 8.
This eliminates the problem when tightened, and further strengthens the degree of the wedge-shaped connection.

Note that the housing can be removed by simply removing the screws 8.

The above explanation is for the case where the housing 1 is fixed at an angle, but
Naturally, in order to fix this horizontally, the length of the 5' portion of the frame should be shortened.

As explained above, the present invention not only allows extremely reliable fixing of the casing, but also has a simple configuration and can be provided at low cost, so it is effective as a mount device for marine instruments and the like.
