Description
Background of the Invention
1. Field of the Invention
This invention relates to an equipment support structure, and more particularly to an equipment support structure of the type which includes a damper spring for offsetting load applied from an equipment to a damper.
2. Description of Related Art
Generally, in equipment such as precision machinery, for example, a player for playing back a record medium or the like, it is highly desirable to minimize or substantially prevent transmission of external vibration to the equipment. For example, when a compact disc (CD) player which has been recently widely sold, has applied thereto external vibration during the playing-back of a compact. disc, a failure in reproducing a part of a signal stored on the compact disc due to skipping or the like occurs in reading-out of data. For this reason, in the installation of a compact disc player of the vehicle mounted type which is adapted to be mounted on a vehicle capable of generating vibration, equipment support structure is used which is constructed so as to support the player on a mount provided on the side of a vehicle through a damper means which exhibits vibration absorbing ability. The equipment support structure is adapted to cause the damper means to absorb vibration generated from the vehicle to prevent it from being transmitted to the player, resulting in ensuring positive playing-back of the compact disc and protection of both player and compact disc.
Also, such an equipment support structure typically includes a damper spring arranged between the equipment and the mount. The damper spring is engaged at both ends thereof with the center of gravity of the equipment and the mount, respectively, to thereby cancel load applied from the equipment to the damper means. This prevents the load of the equipment from acting directly on the damper means, to thereby prevent deformation of the damper means. Also, the damper spring serves to hold the damper means at a proper position due to its urging force, to thereby prevent the damper means from being exhausted to a degree sufficient to cause the vibration absorbing ability of the damper means to be biased.
Conventionally, as a mount through which the equipment is mounted on the vehicle or the like, an upright or vertical type mount, a horizontal type mount and the like are selectively used depending on a mounting space. Thus, the posture or position of installation or setting of the equipment depends upon the mount used. In order to cause the damper spring to cancel load of the equipment acting on the damper means, it is required to constantly vertically arrange or orientate the damper spring. Therefore, when one type mount is replaced with another type mount, it is required to vary the position of setting of the damper spring. This is generally carried out through a highly troublesome procedure of detaching the damper spring from the one mount, varying the direction of setting of the damper spring and then attaching it to the other mount.
Also, such replacement is manually carried out. However, because the damper spring must be constructed so as to exhibit an urging force sufficiently large to cancel load of the equipment, the handling of the damper spring by manual operation is very troublesome, resulting in operation efficiency being substantially deteriorated.
Summary of the Invention
The present invention has been made in view of the foregoing disadvantages of the prior art.
Accordingly, it is an object of the present invention to provide an equipment support structure which is capable of being readily accommodated to various equipment setting positions or postures.
It is another object of the present invention to provide an equipment support structure which is capable of permitting the vertical arrangement or orientation of a damper spring to be readily carried out irrespective of the posture or setting of an equipment.
It is a further object of the present invention to provide an equipment support structure which is capable of accomplishing the above-described objects with a simple construction.
In accordance with the present invention, an equipment support structure is provided. The equipment support structure includes a damper means through which equipment is mounted on a mount, a damper spring for offsetting any load of the equipment applied to the damper means, and a link pivotally mounted on one of the mount and equipment so as to be pivotally moved depending upon the position or setting of the equipment. The damper spring is arranged between the link and the other of the mount and equipment so as to be pivotally moved in association with the pivotal movement of the link.

Detailed Description of the Preferred Embodiments
Now, an equipment support mechanism according to the present invention will be described hereinafter with reference to the accompanying drawings.
FIGS. 1 to 3 show an embodiment of an equipment support mechanism according to the present invention, which is adapted to be variably arranged between a position shown in FIGS. 1 and 2 for supporting an equipment of the upright type and that shown in FIG. 3 for supporting equipment of the horizontal type. More particularly, the equipment support mechanism of the illustrated embodiment is constructed so as to support thereon both an equipment of the upright type of which the longitudinal axis extends in the vertical direction and equipment of the horizontal type of which the longitudinal axis extends in the horizontal direction.
For this purpose, the equipment support structure of the illustrated embodiment includes at least one damper 10 acting as a vibration absorbing element. In the illustrated embodiment, two such dampers 10 are provided on both vertical ends of each of both sides 12 of a piece of equipment 14 to be supported by the equipment support structure, to thereby prevent vibration from being transmitting to the equipment 14. The dampers 10 each are engaged with or connected to a damper plate 16 through a pin 18 mounted on the damper plate 16 so as to extend therefrom toward the equipment 14. The damper plate 16 is mounted on a mount (not shown) provided on the side of a vehicle or the like and formed at the central portion thereof with a guide 20. In the illustrated embodiment, the guide 20 comprises an arcuate aperture so as to extend over an angular range of 90.degree..
The equipment support structure of the illustrated embodiment also includes a link or damper link 22 pivotally arranged so as to extend on both sides of the damper plate 16 through the aperture 20 of the damper plate 16, so that it may be pivotally moved at the distal end 24 thereof about the proximal end 26 thereof over the angular range of 90 degrees through the arcuate aperture 20. Thus, the arcuate aperture 20 serves as a guide for pivotally moving the damper link 22 therethrough. In the illustrated embodiment, the damper link 22 is mounted at the proximal end 26 thereof on the damper plate 16, and the proximal end 26 of the damper link 22 is positioned outside the damper plate 16 and the distal end 24 is positioned inside the plate 16.
Further, the equipment support structure of the embodiment includes a damper spring 28 arranged between the damper plate 16 and the dampers 10 in a manner to extend vertically or perpendicular to a direction of load of the equipment 14 applied to the dampers 10. The damper spring 28 is so arranged that its proximal end 30 is mounted on the equipment 14 so as to be positioned at substantially the center of gravity of the equipment 14. In the illustrated embodiment, the proximal end 30 of the damper spring 28 is engagedly held on a hook 32 mounted on the equipment 14. Also, the damper spring 28 is operatively connected at the distal end 34 thereof to the distal end 24 of the damper link 22, resulting in being pivotally moved about the proximal end 30 in association with the pivotal movement of the damper link 22. The damper spring 28 constructed as described above functions to cancel load applied from the equipment 14 to the dampers 10 and constantly hold the dampers 10 at an appropriate position relative to the damper plate 16.
Further, in the illustrated embodiment, the arcuate aperture 20 of the damper plate 16 is provided at each end thereof with a stopper 36, against which the damper link 22, when reaching each end of the stroke of pivotal movement thereof is engagedly abutted, resulting in being held at the stroke end. Thus, the stoppers 36 serves as a lock means for regulating the pivotal movement of the link 22.
As described above, the damper link 22 and damper spring 28 are engaged with each other through the respective distal ends 24 and 34, so that the damper spring 28 may be pivotally moved in association with the pivotal movement of the damper link 22. In illustrated embodiment, the damper link 22 is so positioned that its proximal end 26 about which the link is pivotally moved is deviated toward the distal ends 24 and 34 of the link 22 and spring 28 from the proximal end 30 of the damper spring 28 about which the damper spring 28 is pivotally moved. Such construction causes the stroke of pivotal movement of the distal end 24 of the damper link 22 to be reduced or shortened as compared with that of the distal end 34 of the damper spring 28. This results in an urging force applied from the damper spring 28 to the damper link 22 when the damper link 22 is abutted at the distal end 24 against the stopper 36 being directed toward the stopper 36, so that the holding of the damper link 22 on the stopper 36 may be positively carried out.
Now, the manner of operation of the equipment support structure of the illustrated embodiment will be described hereinafter with reference to FIGS. 1 to 3.
When the equipment support structure which is arranged so as to support the equipment 10 of an upright type as shown in FIGS. 1 and 2 is to be used for supporting an equipment 10 of the horizontal type as shown in FIG. 3, the damper link 22 is pivotally moved manually or using a suitable means such as a screw driver or the like to a position shown in FIG. 3, leading to pivotal movement of the damper spring 28 in association with the pivotal movement of the damper link 22. This causes the damper link 22 to be abuttedly engaged with the stopper 36, resulting in the damper spring being held in the vertical direction as shown in FIG. 3. At this time, the elastic force of the damper spring 28 is directed in a direction toward the stopper 36, to thereby urge the damper link 22 in the direction of pivotal movement thereof, because the proximal end 26 of the damper link 22 and the proximal end 30 of the damper spring 28 are deviated from each other. Also, when the proximal end 26 of the damper link 22 is abutted against the stopper 36, the elastic force of the damper spring 28 is applied to the damper link 22, leading to a secure holding of the damper link 22 on the stopper 36.
As will be noted from the above, in order to accommodate the equipment support structure of the illustrated embodiment to equipment of which setting angles are different by 90 degrees from each other, it is merely required to pivotally move the damper link by 90 degrees, resulting in the damper spring being constantly vertically held with respect to each of the equipments. Thus, it will be understood that the embodiment effectively eliminates, when the posture of setting of equipment support structure is to be varied, the troublesome operation of detaching the distal end of the damper spring from one mount, varying the angle of setting of the damper spring and then mounting the damper spring on another mount, as encountered with the prior art. Also, in the embodiment, the proximal end 26 of the damper link 22 is deviated from the proximal end 30 of the damper spring 28, so that the elastic force of the damper spring 28 causes the damper link 22 to be more securely held on the stopper 36.
FIGS. 4 to 7 show another embodiment of an equipment support structure according to the present invention, which is constructed in such a manner that the proximal end 26 of a damper link 22 is positioned on a line defined by connecting the proximal end 30 of a damper spring 28 and its distal end 34 to each other. In the illustrated embodiment, the proximal end 26 of the damper link 22 coincides with or is positioned on the proximal end 30 of the damper spring 28. Also, in the embodiment, a damper plate 16 is formed at the portion thereof between the proximal end 26 of the damper link 22 and an arcuate aperture 20 with an additional arcuate aperture 38 of a scaled-down shape similar to the aperture 20. In the aperture 38 is movably fitted a screw 40, which is tightened to hold the damper link 22 at a desired position, resulting in functioning as a lock means for regulating the pivotal movement of the damper link 22. For this purpose, the screw 40 may be inserted through the damper link 22 as shown in FIGS. 4 and 5.
The remaining part of the embodiment may be constructed in substantially the same manner as the embodiment shown in FIGS. 1 to 3.
In the embodiment of FIGS. 4 and 5 constructed as described above, when the screw 40 is released, the damper link 22 may be pivotally moved, resulting in the damper spring 28 being likewise pivotally moved. The proximal end 26 of the damper link 22 is positioned so as to coincide with the proximal end 30 of the damper spring 28, so that the equipment support structure of the embodiment may be varied from the position for supporting an equipment of the upright or vertical type shown in FIGS. 4 and 5 to an oblique position for supporting an equipment of the oblique type shown in FIG. 7 as well as a position for supporting an equipment of the horizontal type shown in FIG. 6. At each of the positions, the damper spring 28 is kept vertical. Thus, the structure of the embodiment permits the damper spring 28 to be constantly vertically set irrespective of the angle of installation or setting of an equipment.
In the embodiments described above, the equipment support structure is provided on the damper plate, however, the present invention is not limited to such construction. The link may be arranged on any one of the mount and equipment. For example, the link may be so arranged that the proximal end thereof is positioned at the center of gravity of the equipment and the damper spring may be provided on the side of the mount. Such arrangement likewise exhibits substantially the same function and advantage.
As can be seen from the foregoing, the present invention is constructed in the simple manner so that the link, which is pivotally moved depending upon the position of setting of an equipment, is pivotally mounted at the proximal end thereof on one of the equipment and mount for supporting the equipment through the damper means and the damper spring is arranged between the link and the other of the mount and equipment for offsetting any load applied from the equipment to the damper means. Such construction permits the angle of setting of the damper spring to be varied depending upon the particular equipment by merely pivotally moving the link to keep the damper spring vertical, resulting in the operation of varying the angle of setting of the damper spring being accomplished with high efficiency.
While preferred embodiments of the invention have been described with a certain degree of particularity with reference to the drawings, obvious modifications and variations are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
