Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for vibration-proofly supporting a vibration-isolated support object on a vibrating body in the X-, Y-, and Z-axis directions of a rectangular coordinate axis system.

Conventional technology Conventionally, in order to provide vibration-isolated support for a device to be protected from vibration, such as a computer, on a vibrating body such as a car, the following steps have been taken: 1. Remove the vibration-isolated support from the vibrating body. 2. The support body to be vibration-isolated shall be in the shape of a cube or rectangular parallelepiped, and the vibrating body shall be supported by a similar cube or rectangular parallelepiped shape but supported by rubber, coil springs, leaf springs, air springs, etc. A space slightly larger than that of the vibration-isolating support is formed, and the vibration-isolated support is loosely housed inside this space of the vibrating body, and the outer peripheral surface of the vibration-isolated support and the vibrating body are A method such as installing a buffer body in each of the six gaps between the side wall or the top wall and the bottom wall of the space or the side wall or the top wall facing each other is a method. It has been adopted.

Problems to be Solved by the Invention However, in these conventionally known methods, the spring member that supports the weight of the vibration-isolated support also serves as a buffer member, and therefore it is difficult to fully exhibit the vibration-isolating effect. This would require the use of a spring member with a low spring constant, which would increase the vibration amplitude and make handling difficult. To overcome this difficulty, it is necessary to add elements to provide vibration damping.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a novel vibration isolation support device that can reduce the vibration amplitude without adding a member for damping vibration while using a spring with a low spring constant. , that is its purpose.

Z of anti-vibration support 1
This device is characterized by a vibration-proof support device that supports an upper surface 4 ₆ and a bottom surface 4 ₅ facing each other in the axial direction so as to surround each other.

Effect Since the present invention has the above-described configuration, the self-weight of the vibration-isolated support 1 is supported by the spring member 5 having a sufficiently low spring constant, and the X, Y, and Y axes are Similarly, a spring member 7 made of a rubber net or the like having a low spring constant can suppress vibration in three directions.
It can be buffered by U and 7L.

Embodiments Hereinafter, the present invention will be described in detail based on FIGS. 1 and 2 of the accompanying drawings showing embodiments thereof.

As shown in the figure, for example,
A vibration-isolated support 1 having a cubic or rectangular parallelepiped shape having four circumferential sides and one top and bottom surface in the Y and Z-axis directions is attached to the vibrating body 2 for vibration isolation. In order to support the vibration-isolated support 1 on the vibrating body 2,
A space 3 is formed which has the shape of a cube or rectangular parallelepiped that is almost the same as that, but whose dimensions are generally slightly larger than that, and this space 3 is divided into four side walls 3 ₁ to 3 ₄ and bottom wall 3 ₅
The vibration-isolated support 1 is placed inside this space 3, and its four perpendicular circumferential surfaces 4 ₁ to 4 ₄ and bottom surface 4 ₅ form a space formed in the vibrating body 2. 3 and the bottom wall 3 ₅ , respectively, and are arranged parallel _to each other and at approximately equal intervals therefrom. Then, the dead weight of the support 1 to be vibration-isolated is the bottom surface 4 ₅ and
The vibrating body 2 is supported by several spring members 5 having a sufficiently low spring constant in the Z-axis direction, which are disposed between the vibrating body 2 and the bottom wall ₃₅ of the space 3. , In order to buffer the vibration-isolated support 1 from vibration input from the vibrating body 2 with a sufficiently low spring constant, a pair of opposing side walls bounding a space 3 formed in the vibrating body 2, That is, 3 ₁ and 3 ₃ and 3 ₂ and 3 ₃
In addition, each of the side surfaces 4 ₁ to 4 is located at a position whose dimensions are slightly smaller than the height and width dimensions of the opposing sides 4 1 and 4 ₃ and 4 ₂ and 4 ₄ of the vibration-isolated support ₁ , respectively.
4 Each _{4 hooks 6 symmetrically about the center of 4}
are attached in two rows in the length direction of the vibration-isolated support 1, and are attached in two rows in the upper and lower rows on the opposing side walls 3 ₁ and 3 ₃ and 3 ₂ and 3 ₄ of the space 3 of the vibrating body 2. The upper rubber net or rubber string group 7U consisting of two orthogonal sets of strands 7 ₁ and 7 ₂ and two orthogonal sets of strands 7
Rubber nets or rubber string groups 7L consisting of ₃ and 7 ₄ are installed so as to cover the top surface 4 ₆ and bottom surface 4 ₅ of the vibration-isolated support 1, respectively. In addition, the rubber nets or rubber string groups 7 above and below these
The spring constants of U and 7L are set so that they can smoothly follow vibration displacement in the X, Y, and Z axis directions, and provide high frequency isolation and high vibration damping properties.
The spring should be selected to be sufficiently low in the Y and Z axis directions, or should have a predetermined spring constant in each axis direction.

In addition, these rubber nets or rubber string groups 7
It goes without saying that the U, 7L arrangement is not limited to that shown in the drawings, and that other arrangements can be made as necessary to provide separate predetermined damping in each axial direction. It is.

Since the present invention has the above-described configuration, the dead weight of the vibration-isolated support 1 is supported by the spring member 5 having a sufficiently low spring constant in the Z-axis direction, and its X , Y and Z axis directions can be damped by the rubber net or the rubber string groups 7U and 7L.

Effects of the Invention Since the present invention has the above-described structure and operation, the self-weight of the vibration-isolated support is supported by its own support spring member, and the weight of the object is supported in the X, Y, and Z axis directions. This provides an excellent effect in that the vibration amplitude can be attenuated in the Z-axis direction by a rubber net or a group of rubber strings as buffer spring members arranged in the ±directions thereof. Therefore, the present invention provides an optimal vibration-isolating support device for supporting, for example, a computer mounted on an automobile while isolating it from the vibrations of the automobile.
