Crystal mount shock absorber

Claim 2

A shock absorber for a planar crystal connected by electrodes to a base, and including a cover secured to the base encapsulating the crystal the shock absorber comprising: a flexible tubing positioned between said cover and said crystal, surrounding said crystal with spacing in between so that said crystal is free to vibrate in response to electrical signals applied thereto, the shape of the flexible tubing being such that it urges against the inner walls of the cover at a plurality of locations and provides portions therebetween that function as cushions to limit the movement of the crystal in a direction transverse to the plane of the crystal, the cross-sectional shape of said flexible tubing in a direction normal to the axis of the tubing being in the form of an ellipse with the major axis extending along the planar surface of the crystal.

Claim 3

A shock absorber as defined in claim 1 wherein: said flexible tubing engages said cover along the minor axis of the ellipse with the portion between the major and minor axis functioning as said cushions.

Claim 4

A shock absorber as defined in claim 2 wherein: said flexible tubing is formed with apertures along the opposite ends defined by the major axis.

Claim 5

A shock absorber for a planar crystal having electrodes secured to opposite planar surfaces and mounted to a substantially oval base through a pair of electrodes connected to the electrodes on said crystal and including a cover having a substantially oval shape secured to said base for encapsulating said crystal, said shock absorber comprising: an elongated flexible tubing having a substantially ellipsoid shape, said tubing being positioned in said cover so that said tubing resiliently urges against the inner sides of the cover at a plurality of locations and surrounds the crystal so that the major axis of the ellipsoid lies along the plane of the crystal and with spacing between the crystal and the tubing so that the crystal is free to move in response to electrical signals applied to the electrodes, the portions of the tubing between said locations are free to act as cushions to limit the movement of the crystal in response to acceleration and deceleration forces applied to the crystal in a direction transverse the plane of the crystal, and the tubular sides of the tubing adjacent the major axis of the ellipsoid are formed with apertures to avoid contact with said pair of electrodes.

Claim 6

A shock absorber for a planar crystal having electrodes secured to opposite planar surfaces and mounted to a substantially oval base through a pair of electrodes connected to the electrodes on said crystal and including a cover having a substantially oval shape secured to said base for encapsulating said crystal, said shock absorber comprising: an elongated flexible tubing having a substantially ellipsoid shape, said tubing being positioned in said cover so that said tubing resiliently urges against the inner sides of the cover at a plurality of locations and surrounds the crystal so that the major axis of the ellipsoid lies along the plane of the crystal and with spacing between the crystal and the tubing so that the crystal is free to move in response to electrical signals applied to the electrodes, the portions of the tubing between said locations are free to act as cushions to limit the movement of the crystal in response to acceleration and deceleration forces applied to the crystal in a direction transverse the plane of the crystal, and the tubular sides of the tubing adjacent the major axis of the ellipsoid are formed with apertures to avoid contact with said pair of electrodes.

Claim 7

A shock absorber as defined in claim 4 wherein: said tubing is prestressed so that said tubing provides an expanding force against the inner sides of said cover along the minor axis of the ellipsoid.

Claim 8

A shock absorber for a planar crystal connected by electrodes to a base, and including a cover secured to the base encapsulating the crystal, the shock absorber comprising: a flexible tubing initially of a shape such that it has a cross-sectional dimension larger than a cross-sectional dimension of the interior of said cover and being deformed from its initial shape so as to be insertable into said cover, and being inserted into said cover so as to surround said crystal, with prestressing created by the deforming of said tubing causing said tubing to be urged into contact with the inner side walls of said cover which face the planar surfaces of said crystal, said tubing being spaced apart from said crystal so that said crystal is free to vibrate in response to electrical signals applied thereto, and portions of said flexible tubing not urged into contact with the interior side walls of said cover cushioning and limiting the movement of said crystal in a direction transverse to the plane of the crystal.

Claim 9

A shock absorber for a planar crystal connected by electrodes to a base, and including a cover secured to the base encapsulating the crystal, the shock absorber comprising: a flexible tubing initially of a shape such that it has a cross-sectional dimension larger than a cross-sectional dimension of the interior of said cover and being deformed from its initial shape so as to be insertable into said cover, and being inserted into said cover so as to surround said crystal, with prestressing created by the deforming of said tubing causing said tubing to be urged into contact with the inner side walls of said cover which face the planar surfaces of said crystal, said tubing being spaced apart from said crystal so that said crystal is free to vibrate in response to electrical signals applied thereto, and portions of said flexible tubing not urged into contact with the interior side walls of said cover cushioning and limiting the movement of said crystal in a direction transverse to the plane of the crystal.

Claim 10

A shock absorber as defined in claim 6, wherein the cross-sectional shape of said flexible tubing in its inserted position within said cover, in a direction normal to the axis of the tubing, is in the form of an ellipse with the major axis of the ellipse extending along the planar surface of the crystal.

Claim 11

A shock absorber as defined in claim 7, wherein said flexible tubing engages said cover along the minor axis of the ellipse with the portion between the major and minor axis functioning as said cushions.

Claim 12

A shock absorber as defined in claim 8, wherein said flexible tubing is provided with apertures along the opposite ends defined by the major axis thereof, through which apertures edges of said crystal extend while remaining spaced apart from the flexible tubing itself.
