Abstract

PURPOSE:To reduce an inertial force of impact by interposing an elastic support member between a bracket fixed to a CRT unit and a housing accommodating them. CONSTITUTION:A structure wherein a CRT unit 22 and each of brackets 26, 28 and 30 formed integrally therewith are supported with dampers 38 interposed in relation to a housing is provided, and thereby the CRT unit is protected surely from vibration or an impact force. The mass of the CRT unit and each of the brackets 26, 28 and 30 are smaller, in particular, by that of the housing 40 than conventional ones. According to this constitution, vibration and an inertial force of impact are smaller than ones in the case when the housing 40 is supported with an elastic support member interposed in relation to a first hull bracket 46 and a second hull bracket 50, and absorption of the vibration and the inertial force by the dampers 38 is facilitated.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a CRT unit mounting structure, and particularly to a CRT unit mounting structure for a basic structure, for example, a vibrating structure such as a ship or a vehicle.
This relates to the structure for mounting the T unit.

[Conventional technology] CRT units installed in conventional ships and vehicles are
The T unit is housed and fixed in a housing via a bracket or the like, and the entire housing is attached to the hull of a ship or the like.

Here, the CRT is protected from the vibration and impact force from these ships and vehicles.
In order to protect the unit, a buffer member such as an elastic support member is provided between the housing and the basic structure such as the hull.

[Problems to be Solved by the Invention] However, in this structure in which a buffer member is provided between the housing and the hull, there is a problem in that if the housing is firmly fixed to the hull, the buffer function deteriorates.
In addition, the mass of the housing increases as the parts that need to be protected from vibration and impact force increase, and the impact inertia increases, resulting in C
There is a problem in that the RT unit itself cannot be sufficiently protected.

The present invention has been made in order to eliminate these drawbacks of the prior art, and its purpose is to reliably protect the CRT unit from vibrations and impact forces, and to firmly fix it to the hull or vehicle. The purpose of the present invention is to provide a CRT unit mounting structure that allows for

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a CRT unit in which a CRT unit is housed in a housing via a bracket fixed to the CRT unit, and the housing is attached to a basic structure. In the mounting structure, an elastic support member is interposed between the bracket and the housing.

[Function] In this way, by interposing the elastic support member between the bracket fixed to the C and RT unit and the housing that houses the CRT unit, only the CRT unit and bracket are the objects to be protected from vibration. Since the mass of the CRT unit is reduced and vibration or impact inertia is reduced, the protection function of the CRT unit is increased.

[Example] The present invention will be explained below based on embodiments shown in the drawings.

First, FIG. 1 shows the appearance of an example in which a CRT unit is mounted on a small boat. This boat 10 is equipped with an outboard motor 14 on a stern board 12, and the outboard motor 14 is operated by operating a handle 16 in the driver's seat.
Steering 4 left and right. A CRT unit 22 is installed on the dash board in front of the driver's seat to convert and display signals from the radar antenna 18 and Loran C information receiving antenna 20. Further, fish school information from a fish school detection sensor 24 provided on the stern board 12 can also be displayed as an image on the CRT unit 22.

2 and 3, a first embodiment of the present invention is shown. A first bracket 26 is fixed to the outer periphery of the screen portion (the left side portion in FIG. 2) of the CRT unit 22.
The bracket 26 is fixed to a third bracket 30 via a second bracket 28 at its seventh rank.

31 and 32 are mounting screws, respectively. As shown in FIG. 2, the third bracket 30 is formed into a substantially U-shape and is arranged to surround the CRT unit 22 and the substrate 34 of the CRT unit 22, except for the screen portion. The board 34 is attached to the third bracket 3 by the mounting screw 33.
Fixed to 0.

Collars 36 are attached to two locations on both sides of the third bracket 30 so as to protrude outward, and the collars 36 are attached to the third bracket 30 at their flange portions.
It is fixed to the inner surface by welding etc. 3 each color
On the outer periphery of the shaft portion of 6, there is a damper 3 as a rigid support member.
8 is installed. A groove 39 is formed on the outer periphery of the central portion of each damper 38, and a housing 40, 40, which is divided into two parts, is mounted so as to sandwich this groove 39 from below L. When the housings 40.40 are assembled together, the housings 40.40 have a cylindrical shape with a bottom, with the screen portion of the CRT unit 22 open.
40 are fixed to each other by a plurality of bolts 42 and nuts 43.

The housing 40 that accommodates the CRT unit in this manner has a substantially U-shape and is fixed to a first hull bracket 46 fixed to an opening of the hull 44 via a mounting bolt 48 or the like. Furthermore, this housing 40 has a second hull bracket 5 having an abbreviated shape as shown in FIG.
It is also fixed to the hull 44 by 0.

Note that 52 is a transparent acrylic plate placed in front of the screen portion of the CRT unit 22, and 54 is a frame that covers this acrylic plate 52 and the front end of the opening of the housing 40.

According to the embodiment having the above configuration, the CRT unit 2
2 and each bracket integrated into the housing 40
The structure is such that the CRT unit 22 is supported through a damper 38, and the CRT unit 22 is reliably protected from vibration or impact force. In particular, the mass of the CRT unit 22 and each bracket is smaller than that of the conventional housing 40, and therefore the housing 40 is smaller than the mass of the first hull racket.
6 or the second hull bracket 50 via an elastic support member, the vibration and impact inertia force is smaller, and the vibration and impact force can be easily absorbed by the damper 38.

Also, C is already inside the housing 40 via the damper 38.
Since the structure supports the RT unit 22, such a mounting structure can be assembled within the manufacturing factory.
The reliability of the support structure is further improved compared to when it is installed on the market. Further, the housing 40 is connected to the hull 44.
It can also be firmly fixed to the base, making the overall mounting structure strong.

4 and 5, another embodiment of the present invention is shown, which differs from the previous embodiment in that the CRT unit 22 includes a portion of each bracket 26, 28, 30. A front damper 60 is interposed between the screen portion and the housing 40 so as to overlap almost the entire periphery, and even at a position near the rear end, the outer periphery of the third bracket 30 and the inner periphery of the housing 40 are connected. This is because a rear damper 62 is interposed between them.

This embodiment can also achieve the same effects as described above, and can also seal the gap between the outer periphery of the screen portion of the -CRT unit 22 and the opening of the hull 44 with the front damper 60. This has the effect of preventing water from entering through the opening of 44.

[Effects] As explained above, according to the present invention, since the elastic support member is interposed between the bracket fixed to the CRT unit and the housing housing them, the CRT unit itself is protected from vibration and impact force. becomes more certain, and C
This has the effect of reducing the impact inertia force on the RT unit.
