Abstract

A caliper gauge for measuring the thickness of a pane of glass without having to remove the pane from its housing or frame, having sufficient dimensions to be used on modern standard frames, including double glazed units. The caliper comprises a sliding rule which has measurement markings on both sides. The caliper has a reflection device which can calculate the individual thicknesses of glass panes, along with the overall thickness, in double glazed units. The reflection device is used by observing reflections of different size shapes (squares) and seeing which ones just touch when viewed from a specific angle. The caliper body comprises a sloped portion used to hold the reflection gauge at 45 degrees to the glass when in use (see figs 1-4).

Description

I
Glass Gauge This invention relates to a device for measuring the thickness of single and double pane glass.
When a person, usually a professional glazier, wishes to replace a pane of glass they have to obtain accurate dimensions, including the glass thickness. Using conventional tools to measure the thickness can prove difficult, inaccurate and sometimes impossible without removing the installed glass from its frame typically modem units are double glazed and housed in robust UPVC units. Having to remove the glass is time consuming and sometimes dangerous. Conventional tools have limitations not only to the type of units but also in the circumstances that they are used in, including but not withstanding dark locations, awkward locations where the user might be up a ladder and other challenging locations. To overcome this we have invented a gauge for measuring glass thickness accurately which can be used on modem standard frames in any location without having to remove the glass from its housing or frame.
* The inventions dimensions cover all types of standard doors and windows * The invention can be used ambidextrously * The invention has only one moving part for accuracy * The invention can be used by a user with impairments or physical injuries * The invention uses a calibrated glazing scale to avoid inaccurate readings * The invention has a scalloped area on both sides to identify the correct thickness * The invention has ball point tips to measure accurately even at an angle * The invention is made from engineering-grade plastic for strength and rigidity * The invention has an ergonomically designed, double sided ruler for easy storage * The invention has a special notch so the rule cannot slide out of the gauge * The invention has a reflection device to gauge single pane thickness on double paned units * The invention has a platform to enable the user to hold the gauge at exactly 45 degree angle as the reflection device requires * The invention has a built-in border to protect the reflection device from damage * The invention has a channel section for strength, rigidity, grip and to reduce weight The invention will now be described solely by way of example and with reference to accompanying drawings in which: * Drawing 1: shows a 3D view of the invention shown in locked position', highlighting different components * Drawing 2: shows a close-up 3D view of the invention, highlighting the area where the rule and cover plate are fixed in place.
* Drawing 3: shows the rule close-up in a top and side view, detailing the notch and grip.
* Drawing 4: shows a close-up of the gauge, detailing the design which allows the ruler to slide in and out and the scalloped design.
* Drawing 5: shows the gauge being used to measure around a window! door frame.
* Drawing 6: shows all the components which, when assembled, constitute the invention * Drawing 7: shows cross-sections through the invention identifying the channel section used, including area of important 45 degree angle used in the reflection device * Drawing 8: shows a close up of the ball point joint for total accuracy * Drawing 9: shows the scale and graduations used on the rule * Drawing 10: shows the dimensions of the invention * Drawing 11: shows the reflection device and how to use it In Drawing 1, the invention is shown assembled and in its locked' position its separate components include; the rule, fig 1, the reflection device, fig 2 and the cover plate, fig 3. It is designed to fit around modem standard frames to measure the thickness of installed glass without having to remove it. The rule, Drawing 3, which has a specially developed calibrated scale Drawing 9, is fixed in place using a number of screws clamping the cover plate tightly in place. This design, as detailed in Drawing 2, then allows the rule to slide out of the gauge enabling the user to place the gauge around the intended frame which houses the glass. The rule has a notch, Drawing 3 -fig 1, so as to stop it falling out of the gauge during use. The rule has an ergonomically-designed serrated handle to allow more grip in sliding the rule out of the gauge, Drawing 3 -fig 2. Once the whole gauge is past the bulky frame the rule can then be slid back until both points touch the glass, Drawing 5. This will then allow the user to read the specially designed calibrated scale on the rule using the special scalloped area, Drawing 4-fig 1, which will show the total thickness in millimetres (the rule can be changed if damaged or a different scale is required). The two points that touch the glass have been deliberately rounded to create a ball-point effect, Drawing 8, which means the user can measure accurately even when the gauge is not perpendicular to the glass.
Unlike conventional tools, the invention has an aperture wide enough to fit around modem standard frames and has enough depth to reach the glass to enable a measurement, see Drawing 10. Also, the rule has a printed calibrated scale, Drawing 9, on both sides to enable an ambidextrous user or even to be used upside down, depending on bow the window or door is hinged, these can vary vastly.
Once the measurement has been taken, to remove the gauge simply slide out the rule, remove the gauge from around the frame and slide the rule back into its locked position where the rule fits into the design of the gauge for easy storage as there are no protruding angles, Drawing 1.
Unlike conventional tools the gauge has a reflective device which will determine how thick a single pane of glass is in a double glazed unit, Drawing 6-fig 1. Hold the gauge flat against the glass where the gauge protrudes at a 45 degree angle, Drawing 1 -fig 4 and Drawing 7-fig 2 shows the cross-section. If you look down the angle created by the gauge once it is properly in place, Drawing 11 -fig 1, you will see the reflection in the glass. The box that just touches edges with its own reflection indicates the thickness of the single pane for example in Drawing 11 -fig 2 it is 4mm thick and in Drawing 11 -fig 4 it is 10mm thick.
The reflection device has been housed within a slightly raised area to stop damage and also to enable the user to be in the right position for the reflection device to work successfully, Drawing 11-fig 3.
If you are measuring double glazed glass panels you first fmd out the overall thickness as Drawing 5 shows and then measure the panes on both sides to give you the exact measurements. E.g. Total measurement 18mm = 4mm pane outside + 4mm pane inside with a 10mm spacer-bar.
