Liquid crystal device with an isotropic shock mounting and gasket
First Claim
1. A shock-resistant assembly, comprising:
- a generally planar apparatus having a plurality of edges;
a resilient gasket extending around and receiving the edges of said apparatus;
a carrier for said apparatus into which the apparatus with attached gasket is placed, said carrier having a plurality of projections extending outwardly therefrom;
a bezel into which said apparatus, said gasket and said carrier are placed; and
a shock member mounted on each projection and engaging a surface on the interior of a housing into which said assembly is placed, to absorb a shock of sudden impact.

Abstract
An isotropic shock mounting to prevent damage to electronic components such as a display mounted in a hand-held signature capture terminal includes a shock gasket which extends around the edges of the display, a carrier in which the display is disposed, a formed metal bezel within which the carrier fits having a cut-out portion through which the display can be viewed, and a plurality of shock grommets positioned at the corners of the carrier to coact with the interior of the housing of the hand-held terminal. This arrangement provides for torsional and beam strength, elastic support of the display, strain relief for TAB and PCB connections, and controlled isotropic deceleration in case of an impact resulting from a fall of the hand-held terminal.

24. A method for assembling a shock-resistant assembly for use in a product having a housing, said assembly including an apparatus to be protected, a resilient gasket dimensioned to fit around the periphery of the apparatus, a bezel into which the apparatus is positioned, a carrier for supporting the apparatus and having a plurality of projections, and a plurality of shock members which can be positioned on said projections for minimizing impact shocks to the apparatus, comprising the following steps:
-
(a) placing the gasket around the periphery of the apparatus; (b) locating the assembly and gasket in the carrier; (c) positioning the assembled gasket, apparatus and carrier within the bezel, with the projections extending outside the bezel; (d) providing retaining means to retain the assembled gasket, apparatus and carrier within the bezel so that the gasket is compressed between the gasket and the carrier; (e) mounting a shock member on each of the carrier projections; and (f) placing the assembled bezel, gasket, apparatus and carrier in the housing of the product so that the shock members engage the interior of the housing of the product. - View Dependent Claims (25, 26)
