Description

and 80813

The present invention relates to a means for marking the center of installed electrical switch boxes on a plate or panel on which a wall containing electrical or electrical switch boxes is to be coated.

Such marking of the center of a switch box on a plate or panel is now done as follows: from the place where the electrical switch box is placed on the wall, the height and width up to the center are measured. The dimensions are transferred to a plate, which then usually lies on the floor. A hole is then drilled for the switch box, after which the plate is hung on the wall, the switch box being fitted in the drilled hole, to nail the plate thereby. This means a very laborious and time consuming way of working.

Alternatively, proceed as follows: The seal box on the switch box, which is removed for installation, has four spikes that are brushed with toner, such as a marker.

The plate is placed against the wall and pressed against the switch box. This leaves four dots of toner on the spike cover spike. The plate is then taken down and placed on the floor. Opposite points are connected by lines so that a cross is formed. The point of intersection of these two lines then marks the center of the switch box. With this in mind, a hole is drilled in the plate for the switch box, and the ladle can then be hung on the wall again for nailing. This alternative way of working is at least as complex and time consuming as the former.

According to the present invention, it is an object to provide a special tool for use in the marking operation in question, so that the marking can take place quickly and very accurately.

The tool according to the invention is characterized by the features set forth in the claims.

The structural design of the tool and its use are explained below in connection with a preferred embodiment.

An application example of a marking device according to the invention is shown in the drawings, in which Figure 1 shows the device in a plan view from above in an imaginary operating situation; Fig. 2 shows the device according to Fig. 1 in a side view, seen in the direction of arrows II-II in Fig. 1; and Figure 3 shows a side view of the ring part of the device as a separately replaceable part.

The tool shown in the drawings for marking the center of mounted electrical switch boxes on the plates or panels on which the wall containing the switch box or boxes is to be coated comprises a slightly flexible, substantially loop-like main part 1. The free ends of the loop 1 have two cooperating marking members, namely an annular end 2 and a spike-like marking member 3, the tip 3 of which is located in the center of the ring head 2.

The diameter of the ring head 2 is adapted to the diameters of the electrical switch boxes, the center of which must be marked on the plate or panel on which the wall is to be coated, so that the ring 2 can be threaded on top of the switch box. Since the diameters of such electrical switch boxes have several different dimensions, it is most practical to arrange the ring head 2 as a separate part (see Fig. 3) and keep the rings 2 in different dimensions than to use several devices with different ring end diameters, although this possibility is conceivable.

According to Fig. 3, a fastening plate 4 with edge notches 5 is formed in the ring part 2, which fastening plate is intended to be inserted into the sleeve part 6 formed at the end of the tool loop 1, the sleeve part 6 is formed for this purpose. notch 5. The resilient latch member 8 in the loop 1 confirms that the ring part 2, 4 remains securely in place, but allows the ring part to be replaced by another ring part.

The annotation tool is used as follows:

The plate on which the wall containing the electrical switch box is to be coated is fastened, for example, with two pins at the top directly to the wall. The tool 1 is then threaded into the area of the switch box installed from the side of the plate so that the foot provided with the loop part 2 of the loop comes into the inner surface of the plate and the foot of the loop provided with the spike marking member 3 comes into the outer surface of the plate. The ring part 2 is then threaded onto the electric switch box, after which the center of the switch box is marked on the plates by hitting the end 3 'of the marking member 3. As mentioned, the tip 3 of the marking member remains exactly in the center of the ring 2. A hole is then drilled for the electrical switch box without removing the plate from the wall, after which the plate is pressed against the wall for nailing.

Claims (2)

1. A tool for marking the midpoint of mounted electrical junction boxes on a plate or panel, characterized in that the implement is formed with an elongated, elongated, preferably somewhat resilient body (1), each free end of which is provided with two cooperating markings. means, namely a ring (2) and a suitable spike-shaped marking means (3), the tip of which is located at the center of the ring, while the inner circumference of the ring (2) is adapted to the outer circumference of the junction box, the center of which is to be marked on the plate or panel , so that the ring can be threaded onto the junction box while the plate / panel hangs between the two legs of the jaw (1), whereby the center of the junction box can be marked by the tip of the marking member (3) in the plate / panel. Gear according to claim 1, characterized in that the ring (2) is interchangeable on the main part (1).
