Drilling and installation tool for flush-mounted device boxes and hollow wall device boxes
The BMSS-1 tool addresses the inefficiency of traditional device box installation by enabling quick and precise alignment and secure mounting of electrical devices in walls using core milling and threaded pins, reducing installation time and simplifying the process across different wall conditions.

AI Technical Summary
Existing electrical and electronic devices require precise horizontal, vertical, and axial alignment during installation, necessitating multiple steps and tools for correct depth and curvature, which is time-consuming and inefficient.
The BMSS-1 tool allows for direct core milling of holes for device boxes with built-in spirit levels, using cylindrical threaded pins for secure and easy installation, eliminating the need for drilling, screws, and tools, and enabling installation in both finished and unfinished walls.
Reduces installation time from 1.5 to 12 seconds per device box, allowing for precise and efficient installation of multiple boxes without imprecision or tools, suitable for various wall types.

Abstract
Description
State of the art
[0001] Sockets, switches, control actuators, thermostats and other electrical and electronic devices can only be permanently installed in accordance with standards if the corresponding switch boxes have previously been installed exactly horizontally, vertically, at the correct depth, without axial inclination and without curvature inwards or outwards.
[0002] Currently, the classic installation of device boxes takes place in several steps: measuring (meter rule) the position in a wall, marking the drill holes, milling holes, installing the device boxes, aligning the device boxes vertically, horizontally and axially with a spirit level or laser and ensuring the correct installation depth. innovation
[0003] Instead of the usual several steps of marking the position and the correct distances of the device boxes, milling the holes in the supporting wall (solid or hollow wall), finally connecting the device boxes to the wall with plaster, construction foam or mineral plaster and then checking their position again with the spirit level and aligning them so that the device boxes do not protrude too deeply into the wall or protrude too far from the wall, which would make the subsequent installation of the devices difficult or impossible, the use of the powder-coated drilling and installation tool BMSS-1 ( Fig. 1 Pos.1) involves several work steps that significantly impact the preparation and installation time. While the installation of flush-mounted device boxes in a wall usually takes between 1.5 and 2 minutes, the BMSS-1 reduces this time to 10 to 12 seconds. How it works
[0004] The BMS5-1 is positioned at the appropriate point on the wall, with the built-in spirit levels ( Fig. 1 Pos.6) are precisely aligned and the holes for the device boxes are core milled ( Fig. 1 Pos.4) directly through the BMS5-1. After milling the wall holes, the device boxes are connected to each other and placed on the cylindrical threaded pins of the BMS5-1 ( Fig. 2 Pos.7). The threaded pins ensure that the device boxes are secure, yet easy to remove. They can no longer move, tip, or bend. The assembly is then inserted into the wall holes already filled with mortar, plaster, or construction foam, and any cables and wires already installed are threaded through the cable entry holes ( Fig. 1 Pos.5) with the spirit levels of the BMSS-1 ( Fig. 1 (item 6) and then gently pull the BMSS-1 out. That's it. The assembly stays firmly in place in the wall until the mortar dries. No drilling, no screws, no dowels, no tools required. Instead of just one device box, or a connected device box assembly, 9-10 can be installed in the same amount of time with the BMS5-1.
[0005] The BMS5-1 is designed so that device boxes can be installed in both unfinished walls without plaster and in finished plastered walls ( Fig. 4), or in plasterboard walls. The alignment and mounting holes of the BMS5-1 are provided for the installation of device boxes in plasterboard walls ( Fig.1 Pos. 3). Removable threaded pins, which can be screwed into either the inside or outside of the profile, ensure flexible handling for both plastered and unfinished walls, as well as plasterboard walls. With the invention of the BMS5-1, imprecise, time-consuming work is no longer possible!

Claims
[1] The drilling and assembly tool BMS5-1 can be used for all 3 wall construction types (plastered solid wall, raw solid wall, drywall). characterized by The powder-coated aluminum profile (item 1) - 2 mm thick - can be used with both the flat side (for use on plastered walls and drywall) and the right-angled side (for a raw wall without cladding). The height of the angled legs is 12 mm and corresponds to the usual applied mineral plaster thickness. The device boxes installed in this way protrude 12 mm from the wall and, once the plastering work is completed, sit flush with the plaster. [2] The BMS5-1 drilling and assembly tool is suitable for all device boxes with a DIN mounting dimension of 68mm and 72mm. characterized by that the distances between the cylindrical threaded pins (pos.7) are 60mm and the connection distance is 11mm and the leg dimension of the centering holes (pos.3) is 62mm and exactly 6mm in size. [3] The BMS5-1 drilling and assembly tool can be used flexibly for a number of 1 to 7 device sockets. characterized by The appropriate number of cylindrical threaded pins (item 7) can be screwed into the designated threaded holes without tools, regardless of the number of device boxes to be installed. The special design of the stainless steel threaded pins allows the BMSS-1 drilling and assembly tool to be used universally and independently of other devices and tools. [4] The use of a spirit level or a leveling laser is not required. characterized by that two precision spirit levels are already integrated into the BMS5-1 drilling and assembly tool.
