Abstract
A protective device made of plastic, which is intended as an instrument housing for a measuring instrument. In order to ensure sufficient shock protection, which assures that the protective device is not damaged by hard shocks, the protective device is assembled from a core which is made of thermoplastic material and at least in sections encloses the housing, and a sheathing, which is made particularly of rubber elastic material.
Claims29
In combination, a measuring instrument housing and a protective device for the measuring instrument housing surrounding the measuring instrument housing,
- the measuring instrument housing comprising a hollow housing body which is constructed and arranged for receiving therein a measuring device, and having an outer surface, a predetermined length and a longitudinal axis, and
- the protective device form-fittingly held by the housing, and comprising:
- a core which is made of thermoplastic material externally surrounding the measuring instrument hollow housing body in sections which are spaced to expose the outer surface of the measuring instrument housing between the sections, the core being fixed to the measuring instrument housing and protecting the measuring instrument housing against shocks, and
- a sheathing surrounding the core and protecting the core against abrasion and penetration by sharp objects,
- wherein the sheathing is at least one material selected from the group consisting of a rubber elastic material, a natural rubber, a thermoplastic elastomer, an ethylene-propylene-diene rubber, and a foil or fabric laminated onto the core;
- and
- wherein the sheathing is held in place between the core and sections of the instrument housing.
In combination, a measuring instrument housing and a protective device for the measuring instrument housing surrounding the measuring instrument housing,
- the measuring instrument housing comprising a hollow housing body which is constructed and arranged for receiving therein a measuring device, and having an outer surface, a predetermined length and a longitudinal axis, the hollow housing body comprising in sections along an outer surface thereof, outwardly facing open channels, each of said channels having a length substantially equal to the predetermined length of the housing body and a longitudinal axis corresponding to the longitudinal axis of the hollow housing body, and
- the protective device form-fittingly held by the measuring instrument housing, and comprising:
- a core which is made of thermoplastic material externally surrounding the measuring instrument housing in sections which are spaced to expose the outer surface of the housing between the sections, the core protecting the measuring instrument housing against shocks, and
- a sheathing surrounding the core and protecting the core against abrasion and penetration by sharp objects,
- a section of the protective device being form-fittingly held in each of the channels, and extending outwardly therefrom
- wherein the sheathing is at least one material selected from the group consisting of a rubber elastic material, a natural rubber, a thermoplastic elastomer, an ethylene-propylene-diene rubber, and a foil or fabric laminated onto the core.
In combination, a measuring instrument housing and a protective device for the measuring instrument housing surrounding the measuring instrument housing,
- the measuring instrument housing comprising a hollow housing body which is constructed and arranged for receiving therein a measuring device, and having an outer surface, a predetermined length and a longitudinal axis, and
- the protective device form-fittingly held by the housing, and comprising:
- a core which is made of thermoplastic material externally surrounding the measuring instrument hollow housing body in sections which are spaced to expose the outer surface of the measuring instrument housing between the sections, the core being attached to the measuring instrument housing and protecting the measuring instrument housing against shocks, and
- a sheathing surrounding the core and protecting the core against abrasion and penetration by sharp objects,
- wherein the sheathing is at least one material selected from the group consisting of a rubber elastic material, a natural rubber, a thermoplastic elastomer, an ethylene-propylene-diene rubber, and a foil or fabric laminated onto the core,
- wherein the core comprises arms which originate from a frame with cylindrical sections, which in sections are form-fittingly received by hollow cylindrical sections, which each has one longitudinal slot, of the instrument housing.
In combination, a measuring instrument housing and a protective device for the measuring instrument housing surrounding the measuring instrument housing,
- the measuring instrument housing comprising a hollow housing body which is constructed and arranged for receiving therein a measuring device, and having an outer surface, a predetermined length and a longitudinal axis, and
- the protective device form-fittingly held by the housing, and comprising:
- a core which is made of thermoplastic material externally surrounding the measuring instrument hollow housing body in sections which are spaced to expose the outer surface of the measuring instrument housing between the sections, the core being attached to the measuring instrument housing and protecting the measuring instrument housing against shocks, and
- a sheathing surrounding the core and protecting the core against abrasion and penetration by sharp objects,
- wherein the sheathing is at least one material selected from the group consisting of a rubber elastic material, a natural rubber, a thermoplastic elastomer, an ethylene-propylene-diene rubber, and a foil or fabric laminated onto the core,
- wherein the core has a framework in the shape of a rectangular prism with longitudinal and cross arms;
- and
- wherein sections of the core are connected by connecting elements which extend through the longitudinal arms of the core.
