DE202013006650U1 - Drilling jig for the subsequent creation of hollow wall box rows - Google Patents

Abstract

Aluminum body with four horizontally arranged hardened steel bushes at a distance of 71 mm and two spirit levels for alignment. (horizontally or vertically)

Description

State of the art

In Trockenbausysthem so-called hollow wall boxes are used to accommodate switching devices for electrical installation. Currently, the cavity wall openings are marked by scale, water balance, pencil and eye size and drilled freehand with a can cutter. Since the center distance from box to box is exactly 71 mm in the case of several cavity wall boxes arranged against each other, in practice this mounting principle is associated with great inaccuracy. It is even more difficult if already can openings are available and more doses should be queued. (horizontal or vertical) There is a high probability of poor execution, requiring follow-up work. This ultimately complicates the exact insertion of the switching devices.

problem

The protection specified in claim 1 to 4 invention is based on the problem to provide a cost-effective and easy to handle mechanical device that ensures a precisely fitting and time-saving repositioning of Hohlwandgerätedosen.

solution

According to the invention, this problem is solved by the features specified in the claims.

Achieved benefits

By the invention, a mechanical solution is offered, which guarantees a quick and accurate positioning positioning commercial hollow wall boxes with little effort and simple, technical means and thus eliminates mainly the quality defects of known Einbringvarianten.

embodiment

The invention will be explained below using an exemplary embodiment.

5 the overall structure with attached centering disc

According to the 1 - 5 the principle solution according to the invention for accurately fitting repositioning of hollow wall boxes is shown such that a teaching body ( 1 ) four drill bushes ( 2 ) and a centering pin ( 3 ) contains. Next are laterally for Justierzwecken two bubble level dragonflies ( 4 ) appropriate. A centering disc ( 5 ) or a centering star ( 6 ) are optionally aufzustecken on the centering pin.

Claims (4)

Aluminum body with four horizontally arranged hardened steel bushes at a distance of 71 mm and two spirit levels for alignment. (horizontally or vertically) Steel centering pin arranged 71 mm to the right or left of the drill bushes for insertion into an existing centering hole to subsequently drill up to four further centering holes for the can mill at an exact distance of 71 mm horizontally or vertically. A centering disc made of Plexiglas with a diameter of 68.5 mm and a thickness of 6 mm, with a center hole of 6.5 mm for insertion onto the centering pin and inserted into an existing can hole, followed by up to four further centering holes for the can milling cutter at an exact distance of Drill 71 mm horizontally or vertically. A centering star made of Plexiglas with a diameter of 64.5 mm and a thickness of 6 mm with a center hole of 6.5 mm for mounting on the centering pin and for insertion into an already inserted cavity wall socket, followed by up to four further centering holes for the can milling cutter at the exact distance 71 mm horizontally or vertically.
