Abstract

A socket handle (100) is described comprising: a handle body (120) extending along a central axis (110) with two opposite ends along the central axis, wherein a holding mechanism (130) is arranged at one end (121) of the two opposite ends (121, 122) or in a region of the handle body (120) which is closer to one end (121) than to the opposite end (122) of the two opposite ends (121, 122), which is designed to be positively engaged during assembly or disassembly in or on a socket (10) in order to enable the socket handle (100) to hold and / or rotate the socket (10) during assembly or disassembly.

Description

[0001] The present invention relates to a socket handle, in particular one which facilitates the installation or removal of a socket.

[0002] When installing electrical sockets in a building under construction, the electrician must push the socket into a wall box and rotate it so that it is horizontal to the ground, which is usually checked using a spirit level. Finally, the electrician must screw the socket to the wall box; these screws are also called appliance screws. In this context, the term "screws" is used interchangeably with "appliance screws," but it refers to both. "Appliance screw" and "screw" are used synonymously.

[0003] Fig. Figure 24 shows a socket 10 known from the prior art, which is to be mounted in a wall box 20. The device screws 30 may already be installed in the wall box. In addition, cables 40 are already connected to the socket 10. Fig. Figure 25 shows a socket known from the prior art after installation, in which the device screws 30 are tightened. The socket 10 comprises a sheet metal 12 extending in one plane, which is usually magnetic and rests against a wall after the socket 10 is installed.

[0004] The problem here is that the metal casing of the socket is very thin, making it difficult to grip. The socket has to be pushed and twisted into the wall box against the resistance of the cables inside. This is often very tedious because the socket is so hard to hold.

[0005] Furthermore, there's the problem that the installer only has one hand available to hold the socket in position while tightening the screw, as the other hand is needed for the actual tightening. Holding the socket in position can sometimes be very difficult. The problem here is that the cables essentially act like a spring. This spring is compressed and twisted when the socket is pushed / turned into position, thus acting like a torsional spring and a linear spring, both pushing the socket outwards and twisting it. After inserting and aligning the socket 10, the installer can use a spirit level 50 that can be attached to the socket 10 to check the desired alignment of the socket. Fig. Figure 26 shows a socket 10 known from the prior art, with a spirit level 50 attached. When tightening the screws, the installer must keep one eye on the spirit level 50 and the other eye on the screwdriver. Here, the terms screwdriver and screw-on screwdriver are used synonymously. Overall, installing a socket is a complex and time-consuming process.

[0006] DE 20 2011 104 234 U1 discloses an installation aid for mounting electrical installation devices. DE 100 33 598 C1 discloses a device for mounting flush-mounted switches and sockets. US 2014 / 0 345 427 A1 discloses a device for mounting mounting plate frames for electrical devices.

[0007] One object of the present invention is therefore to provide a socket handle which facilitates the installation or removal of a socket.

[0008] This problem is solved by a socket handle according to claim 1.

[0009] According to the proposal, the socket handle comprises a handle body extending along a central axis with two opposite ends along the central axis, wherein a retaining mechanism is arranged at one end of the two opposite ends or in a region of the handle body which is closer to one end than to the opposite end of the two opposite ends, the retaining mechanism being designed to be positively engaged during assembly or disassembly in or on a socket in order to enable the socket handle to hold and / or rotate the socket during assembly or disassembly, wherein the retaining mechanism is shaped such that the retaining mechanism positively engages the socket from the outside and inside when the socket handle is attached to the socket.Furthermore, the socket handle can include a spirit level, particularly a digital one, or be connectable to one. Additionally, the socket handle can incorporate an electric screwdriver, which automatically locates the socket's mounting screws and automatically tightens them during installation and loosens them during removal. The electric screwdriver's geometry is designed to match the dimensions of a standard electrical socket.

[0010] The socket handle, used alone or with a spirit level and / or electric screwdriver, facilitates the installation and removal of the socket, thus saving time. Ultimately, this also saves costs, as less labor is required from an installer. A socket handle is proposed that can be securely attached to the socket. This makes it easier to grip and rotate the socket.

[0011] It is understood that individual aspects described in relation to the socket handle can also be implemented as procedural steps for using the socket handle. Possible procedures are discussed in the following image description. Further details are discussed within the context of the following image description.

[0013] Individual aspects of the invention described herein are set forth below. Fig. 1 to 13 and 15 to 23 and Fig. 27 and Fig. 28 described. In the present application, identical reference numerals refer to identical or equivalent elements, and it is not necessary for all reference numerals to be repeated in all drawings. Fig. Figures 14 and 24 to 26 show a socket outlet and wall box known from the prior art, a type of handle such as could also be used in front of the proposed socket handle, and a spirit level to enable a direct comparison with the socket handle according to the invention.

[0014] Fig. Figure 1 shows a socket holder handle 100 according to the invention in a socket 10 with a spirit level 50. Fig. Figure 2 shows an underside of the socket handle 100, wherein a holding mechanism 130 has four magnets 140 and two opposing edges 133 (protrusions 133).

[0015] Fig. Figure 3 shows a schematic side view of the socket handle 100 in a socket 10 during the installation of the socket 10 in a wall box 20. As the Fig. As can be seen, for example, in Figure 3, the handle body 120 extends along a central axis 110 and has two opposite ends 121, 122 along the central axis 110. A retaining mechanism 130 is arranged at one end 121 of the two opposite ends 121, 122, or in a region of the handle body 120 that is closer to one end 121 than to the opposite end 122 of the two opposite ends 121, 122. The retaining mechanism 130 is designed to be positively engaged during assembly or disassembly in or on a socket 10, in order to allow the socket handle 100 to hold and / or rotate the socket 10 during assembly or disassembly. There are several possible configurations for the socket handle 100 and the clamping of the socket 10. Fig. Figures 3 to 7 each show an example of a clamping connection. The clamping connection between socket handle 100 and socket 10 includes clamping from the inside and / or from the outside, which will be discussed in detail later. Furthermore, the socket is as shown in Fig. Figures 3 to 6 show only "passively clamped" connections, i.e., via a positive-locking connection. Socket 10 can also be actively clamped via an actuator 150, as shown in Fig. 7 is shown.

[0016] Preferably, the holding mechanism 130 extends from the handle body 120 at an angle of less than 90 degrees to the central axis 110 (not shown) or perpendicular to the central axis 110. A perpendicular extension of the holding mechanism 130 is, for example, in the Fig. 3 to 6 can be seen. The holding mechanism 130 has a holding mechanism. The end 131 is located opposite the handle body 120. In other words, when extending vertically, the end of the retaining mechanism 131 is perpendicular to the central axis 110. Conversely, when extending at an angle of less than 90 degrees, the end of the retaining mechanism 131 is also at an angle of less than 90 degrees to the central axis 110.

[0017] Fig. Figures 3 to 7 each show a schematic side view of the socket handle 100 with different versions of the holding mechanism 130. In the Fig. Figures 3 to 7 each show the socket handle 100 with a socket 10 to show how the socket handle 100 grips into or onto the socket.

[0018] Preferably, the retaining mechanism end 131 is shaped such that the retaining mechanism 130 positively engages a metal surface 12 of the socket 10 from the outside when the socket handle 100 is attached to the socket 10, as is the case, for example, in Fig. 3, Fig. 4 and Fig. 5 can be seen. As in Fig. As can be seen in Figure 5, the clamping between the handle 100 and the socket 10 is achieved solely by an external clamp. The holding mechanism 130 can, for example, have two opposing edges 133 (protrusions 1330) which serve to clamp the metal surface 12 of the socket 10. This is, for example, in Fig. 2 shown. Fig. Figures 3 to 5 each show the edges 133 (protrusions 133) in a side view.

[0019] In Fig. Figure 6 shows, for example, that the retaining mechanism 130 comprises a portion of the handle body 120 extending along the central axis 110, wherein this portion of the handle body 120 is dimensioned such that it is positively engaged from the inside with the socket 10 when the socket handle 100 is attached to the socket 10. In other words, the portion of the handle body 120 associated with the retaining mechanism 130 engages with the socket 10. The clamping between the handle 100 and the socket 100 is achieved solely by internal clamping.

[0020] In Fig. 3 and Fig. Figure 4 shows, for example, that the retaining mechanism 130 is preferably shaped such that it engages the socket 10 from the outside and from the inside in a form-fitting manner when the socket handle 100 is attached to the socket 10. In other words, the area of ​​the handle body 120 associated with the retaining mechanism 130 engages the socket 10, while the retaining mechanism 130 clamps or grips the socket from the outside with its retaining mechanism end 131.

[0021] As in Fig. As shown in Figure 7, the socket handle 100 or the holding mechanism 130 preferably comprises at least one magnet 140 to create a releasable magnetic connection between the socket handle 100 and a metal housing of the socket 10 when the socket handle 100 is attached to the socket 10. The metal housing of the socket 10 is usually magnetic. More preferably, the socket handle 100 or the holding mechanism 130 may comprise four magnets 140 so that the four magnets 140 are attached to the hatched surfaces 200 (as shown in Figure 7). Fig. (as shown in 8) form a detachable magnetic contact connection with socket 10.

[0022] Preferably, the socket handle 100 includes an actuator 150 to actively couple the socket handle 10 to the socket 10 in a form-fitting manner; in particular, the actuator 150 extends along the central axis 110. The actuator 150 can, for example, be a pneumatic device configured to press at least one pair of jaws 152 against the side walls of the metal housing of the socket when the socket handle 100 engages in and / or against the socket 10. Preferably, the actuator 150 is coupled to the at least one pair of jaws 152, which, when the socket handle 100 engages in and / or against the socket 10, are configured to clamp the socket 10 from the inside and / or outside. Fig. Figure 7 shows the socket handle 100 with the actuator 150 and two pairs of jaws 152. One pair of jaws 152 clamps from the inside (inner jaws 152a) and the other pair of jaws 152 clamps from the outside (outer jaws 152b). The actuator 150 is designed to press the inner jaws 150a outwards against an inner wall of the socket 10. Alternatively or additionally, the pair of outer jaws 152b can be pulled inwards by the actuator 150 to clamp an outer wall of the socket 10. In other words, one pair of jaws 152, 152a, 152b or two pairs of jaws 152, 152a, 152b can each be controlled by one actuator or by several actuators 150, so that only one outer clamping, only one inner clamping, or both an inner and an outer clamping occurs.Actuator 150 could be configured as a linear actuator, driven by an electric motor. Actuator 150 could incorporate or be made of a shape memory alloy. The shape memory alloy could be thermally activated and / or configured as a magnetic shape memory alloy. The actuator could incorporate a magnet or be configured as a magnetic actuator.

[0023] Preferably, the socket handle 100 is coupled to or includes a spirit level 50, wherein the spirit level 50 and the socket handle 100 are detachably connected to a socket 10, and the spirit level 50 is designed to visually indicate a desired orientation of the socket 10. The desired orientation of the socket 10 preferably runs parallel to a region of the earth's surface above which the socket is to be mounted on a wall. For example, Fig. 1 and Fig. 9. The proposed socket handle 100 is used with a spirit level 50. The spirit level 50 can be integrated into the socket handle or can be connected to it as an external element. As an analog spirit level, it indicates the desired alignment visually only.

[0024] Preferably, a digital spirit level 50 is used to indicate the desired alignment of the socket 10 both audibly and visually. When using a digital spirit level, the installer also receives an audible signal when the desired alignment of the socket has been achieved. The digital spirit level 50 indicates the inclination not only visually but also via an audible signal. This allows the installer to focus entirely on the screw and determine the direction of rotation by the sound. In such a case, the installer can then concentrate, for example, on positioning the device screws.

[0025] Preferably, the socket handle 100 includes an integrated electric screwdriver 160, which is designed to automatically tighten at least one device screw 30 of the socket 10 during installation or to loosen it during disassembly. Fig. Figure 12 shows a schematic side view of the socket handle 100 with an electric screwdriver during the installation of a socket. Fig. Figure 9 shows a schematic diagram of an electric screwdriver. The electric screwdriver 160 is rotatable about an axis of rotation which runs parallel to the central axis 110. According to Fig. 12 and Fig. The electric screwdriver has two bits (166) as shown in section 9.

[0026] The electric screwdriver 160 is integrated into the socket handle 100 and is designed to automatically tighten the screw during installation as soon as the socket reaches the desired position, i.e., is straight, meaning horizontal above a piece of ground. This can be achieved using the digital spirit level 50. As soon as the digital spirit level 50 registers that the socket 10 is straight, the electric screwdriver 10 is automatically activated and tightens the screw.

[0027] Preferably, the spirit level 50 or the digital spirit level 50 is coupled to the electric screwdriver 160 integrated into the socket handle 100, wherein the spirit level 50 or the digital spirit level 50 is configured to detect the desired orientation of the socket 10 in order to subsequently transmit a command to the integrated electric screwdriver 160, wherein the integrated electric screwdriver 160 is configured to execute the command, the command comprising automatically tightening the at least one device screw 30 of the socket 10 during installation or automatically loosening it during disassembly. The desired orientation of the socket 10 preferably runs parallel to a region of the earth's surface above which the socket is to be mounted on a wall.The electric screwdriver 160 is coupled to, or includes, a control unit configured to receive a command from the spirit level 50 or the digital spirit level 50 indicating that the socket 10 has reached the desired orientation. Upon receiving this command, the control unit is configured to transmit a further command to the electric screwdriver to automatically tighten at least one device screw 30 of the socket 10 during assembly or automatically loosen it during disassembly. In other words, the command triggered by the spirit level initiates the action of the electric screwdriver 160 to automatically tighten at least one device screw 30 of the socket 10 during assembly or automatically loosen it during disassembly.

[0028] Preferably, the integrated electric screwdriver 160 has a motor 162 or (as, for example, in Fig. (as shown in Figures 19 to 21) a motor 162 and a gearbox 164, wherein the motor 162 or the motor 162 and the gearbox 164 are rotatably arranged in the socket handle 100, whereby the electric screwdriver 160 is rotatably mounted in the socket handle 100. The electric screwdriver 160 is rotatably mounted in the handle body 120. For this purpose, a rotating part of the electric screwdriver 160 is arranged spaced apart from the handle body 120 within the handle body 120. In other words, the handle body 120 has a cavity 350 in which the electric screwdriver 160 is mounted and can be rotated about the central axis 110. The central axis 110 is a rotational axis for the electric screwdriver 160, as is the case, for example, in Fig. Figure 21 shows the part of the screwdriver 160 marked with reference numeral 400, which is rotatably mounted in the socket handle 100 so that the electric screwdriver 160 can be turned towards the screw 30 while the socket handle 100 and the clamp remain in position to hold the socket 10 in the desired position, a horizontal position above the ground.

[0029] Fig. Figure 10 shows a mounted socket 10 with misaligned (angled) screws 30. In Fig. Figure 11 shows that the screws 30 must move on a "circle" with a circumference of 168. In other words, if the electric screwdriver 160 is implemented to be rotatable about the central axis 110, it can be rotated to the screws 30. Therefore, the proposed electric screwdriver 160 is implemented so that it can be rotated about the central axis 110. This allows the bits 166 of the electric screwdriver 160 to be rotated into the correct position. For example, Figure 11 shows... Fig. 12 shown socket 10 with socket handle 100 and electric screwdriver 160, which is rotatable around the central axis 110.

[0030] Preferably the integrated electric screwdriver 160 has one bit 166 or two bits 166 which are arranged on a circular circumference 168, in particular evenly distributed. Fig. Figure 11 shows a schematic top view of a wall box, with a circle having a circumference of 168. The central axis 110 is indicated by a dot at the center of the circle, or rather, at the center of the circumference 168. The circumference 168 defines a trajectory along which the bit 166 or bits 166 of the electric screwdriver 160 can move to locate the screws of a socket or wall box 20. This trajectory lies in a plane perpendicular to the central axis 110 of the socket handle 100 or the electric screwdriver 160.

[0031] Fig. Figure 9 shows a schematic diagram of an electric screwdriver 160. The electric screwdriver 160 comprises the motor 162 and the gearbox 164. Each bit 166 is connected to the motor 162 via at least two deflections 170, in particular wherein a slip clutch 172 can be arranged between each pair of deflections 170 to prevent the respective screw 30 (not shown in Figure 9) from slipping. Fig. 9) is tightened too much. Alternatively or additionally, a measuring device is arranged in the socket handle 100 to detect the motor speed, in particular, where the motor 162 may be designed to switch off if a motor speed limit is undershot. For this purpose, the control unit can receive the detected motor speed and compare it with a stored motor speed limit. If the motor speed limit is undershot, the control unit can issue a further command to the motor 162, after which the motor 162 switches off. In general, if the screw is tightened, the motor 162 rotates very slowly or not at all. Therefore, falling below a minimum speed, which may be defined by the motor speed limit, is equivalent to the screw being tightened.A slip clutch or cut-off device as described above is useful, but not essential. If the motor is weak enough, its torque will not be sufficient to damage the screw or the wall socket. In such a case, a slip clutch and / or cut-off device would not be necessary.

[0032] Preferred are the deflection gears 170, the motor 162 and the associated bit 166, or the deflection gears 170, the motor 162, the associated bit 166 and the slip clutch 172 (as in Fig. (9 shown) are each mechanically coupled to one another via at least one shaft 176 in order to transmit a drive signal from the motor 162 to the corresponding bit 166. As shown in Fig. As can be seen in Figure 9, the deflections 170, the motor 162, the two associated bits 166, and the slip clutches 172 are functionally coupled to one another via a total of seven shafts 176. If the electric screwdriver 160 were equipped with only a single bit 166, the deflections 170, the motor 162, the associated bit 166, and the slip clutches 172 would, for example, be functionally coupled to one another via a total of four shafts 176.

[0033] Fig. Figure 18 shows a schematic side view of the socket handle 100 with electric screwdriver 160 with housing, the housing being defined by the socket holder body 120. Fig. Figure 19 shows a schematic side view of the socket handle 100 with electric screwdriver 160 without housing, i.e., without socket retaining body 120. Preferably, each deflection 170 is formed by a worm gear or by a pair of bevel gears. Two pairs of ball gears are, for example, in the Fig. 18 and Fig. 19 can be seen.

[0034] Fig. 18 and Fig. Figures 19 each show the electric screwdriver 160 with two bits 166, which are arranged diametrically opposite each other on the circumference 168. The circumference 168 is an imaginary circumference. In the side view according to Fig. 18 and Fig. The bits 166 are arranged to the left and right of the central axis 110. The holding mechanism extends around the central axis with a plate 205 on which a projection 210 is arranged (compare with description to Fig. 22 and Fig. 22). Fig. Figure 22 shows a perspective view of the holding mechanism 130 with its plate 205 and the projection 210, which allows clamping from the inside. The ends of the plate 205 have a structure suitable for clamping the socket 10 from the outside.

[0035] Preferably, the motor 162 of the integrated electric screwdriver 160 is rotatable around the central axis 110, whereby the bit (166) or bits 166, which is / are arranged on the circular circumference 168, can be arranged to the screws 30 in a socket 10 to be mounted. Fig. Figure 11 shows the circumference of a circle 168, which is depicted on a wall box 20. When installing the socket 10, the screws 30 are to be inserted into the screw holes 60, where the screw holes 66 are holes in the socket 10 and holes in the wall box, i.e., wall box holes 22. Since the wall box holes 22 and the screw holes 60 lie on the circumference of a circle 168, on which the bits 166 or the bit 166 of the electric screwdriver 160 are also arranged, the wall box holes 22 can be easily and quickly located using the proposed socket handle 100 or with the electric screwdriver 160 in the socket handle 100.

[0036] Fig. Figure 15 shows a socket handle 100 with at least one push button 180 for the wall box 20 without a device screw 30. The device screw 30 is inserted here into the bit 166 of the electric screwdriver 160.

[0037] Preferably, the socket handle 100 comprises at least one probe 180 for locating a screw hole 60 or a screw 30 in a wall box 20. In particular, the at least one probe 180 is a mechanical probe 180 or an optical probe 180 with an image recognition unit (not shown). Fig. Figure 22 shows a perspective view of the socket handle 100 with a view of the probe 180 for locating a screw. The probe 180 is conical in shape (as in Fig. (as shown in Figure 22), the probe 180 has a circular hole 182 in its center, which corresponds at least to the size of a screw head to accommodate the screw head. The probe 180, with its conical shape, is therefore a cone. The cone ensures that the screw 30 slides towards the center, to the hole 182 of the probe 180. The screwdriver bit 166 is located there. As the screw 30 slides towards the center, the electric screwdriver 160 is automatically rotated because the sliding screw exerts a force on the electric screwdriver. In other words, the electric screwdriver 160 is thereby pushed into the correct position. In other words, the sliding screw exerts a force on the probe 180 via the inner side wall of the conical probe 180.The probe 180 is connected to the rotatably mounted electric screwdriver 160, thus transferring the force to the rotatably mounted electric screwdriver 160. This causes the electric screwdriver 160 to rotate. The rotation stops when the screw slides into the small upper hole of the probe 180, where the screwdriver bit 166 is also located. The electric screwdriver 160 has then rotated far enough that the screwdriver bit 166 of the electric screwdriver 160 is positioned directly above the screw head in the wall box.

[0038] The diameter of the lower part of the conical probe 180 is larger than the diameter of the screw head. This ensures that the probe can easily be fitted over the screw head once it has located the screw head. How Fig. As can be further seen from Figure 22, the socket handle 100 has two push buttons. It is conceivable that the socket handle 100 has only a single push button 180. The number of push buttons 180 can correspond to the number of bits 166 of the socket handle 100 with electric screwdriver 160. The push button serves to turn the electric screwdriver 160 over the screw.

[0039] Fig. It can further be seen from Figure 22 that an area near the probe 180, which extends perpendicularly to the central axis 110 as a plate 205, has a protrusion 210. The protrusion 210 has a contour shaped such that it can engage positively in a socket 10. The protrusion 210 corresponds to an example of the holding mechanism 130 with positive locking from the inside as described herein. The internal locking is also described in Fig. 3, Fig. 4, Fig. 6, Fig. 12 and Fig. Figure 15 shows a schematic representation. Plate 205 corresponds to an example of the holding mechanism 130 with positive-locking clamping from the outside. The clamping from the outside is also shown in Fig. 3, Fig. 4, Fig. 5, Fig. 12 and Fig. 15 can be seen schematically.

[0040] Preferably, each bit 166 is coupled to a probe 180, in particular via a spring 184. Fig. Figure 19 shows, for example, the coupling between the bit 166 and the probe 180 via the spring 184. The probe 180 has the circular hole 182 through which the bit 166 can grip a screw head held by the probe 180 and tighten it during assembly. The spring 184 can also serve as a guide when tightening the screw, being compressible along a line parallel to the central axis 110 during tightening.

[0041] Preferably, the socket handle 100 includes a clamping device 190 to manually bring the electric screwdriver 160 into contact with the socket 10 during installation or removal. It should be noted that the length of the screw protruding from the wall box decreases as the screw is tightened. This means the electric screwdriver must be repositioned to maintain contact with the screw head. Therefore, pressure must be continuously applied to the clamping device while tightening the screw. The clamping device is, for example, located in Fig. 19 and in Fig. Figure 20 shows the clamping device 190, which is coupled or connected to the electric screwdriver 160 in the socket handle 100 via a further spring 184. The spring 184 of the clamping device 190 serves to press the electric screwdriver 160 towards the wall socket with a small force. This force is sufficient for the screwdriver bit 166 to make contact with the screw head.

[0042] This force is insufficient for tightening the screw. In other words, to position the electric screwdriver 160, the technician does not need to press on the pressure device (as the spring force is sufficient). However, as soon as the electric screwdriver 160 is activated by the (electronic) spirit level 50, the technician must press on the pressure device 190, as more pressure is now required.

[0043] Several shapes are possible for the socket handle 100. A cylindrical shape for the socket handle 100 is preferred, as can be seen in most of the figures in the application. It is important that the handle offers a good grip and that there is sufficient space for the electric screwdriver 160, if necessary. Fig. Figure 23 shows a possible alternative to the cylindrical shape. Fig. Figure 23 shows a possible form of a socket handle as a "cross handle". It must be noted that the electric screwdriver 100 must be placed under the cross handle.

[0044] When using the 100 socket grab handle, two initial situations must be distinguished. Initial situation

[0045] Sometimes the device screws 30 are already in the wall box 20 (see Fig. 13a). Then, push the socket 10 over the round holes of the socket 10 over the screws 30 ( Fig. 13b) and then turns them straight in the elongated holes of socket 10 ( Fig. 13c).

[0046] In this case, the electric screwdriver 160 should find the screw 30 and turn towards it (either automatically or manually) as soon as the socket handle 100 is placed on the socket 10.

[0047] This can be done, for example, using the mechanical probe 180. The electric screwdriver 160 is rotated until the probe 180 locates screw 30. Another possibility would be optical probing via image processing.

[0048] The proposed socket holder handle could, for example, be used to carry out the following procedure 270 for mounting a socket 10, as shown in Fig. Figure 27 shows: providing a wall box 20 in which appliance screws 30 are arranged (step 271); providing a socket to be mounted on the wall box 20 (step 272); positioning a socket handle 100 on and / or in the socket, wherein the socket handle 100 has an integrated electric screwdriver 160; (step 273) and subsequently arranging the socket 10 over the appliance screws so that the heads of the appliance screws 30 protrude through elongated holes in the socket 10; (step 274) locating the appliance screws using the electric screwdriver 160 (step 275); and tightening the appliance screws 30 using the screwdriver (step 276).

[0049] Furthermore, the procedure could be carried out using a digital spirit level 50, whereby a step of finding a desired orientation of the socket 10 could be performed before tightening. Second starting situation

[0050] Sometimes the device screw 30 is not yet inserted into the wall box 20, as shown in Fig. 14 can be seen.

[0051] In this case, the device screw 30 can either be screwed into the wall box 20 by hand, proceeding as in the first initial situation, or the device screw 30 can be attached to the electric screwdriver 160 and held in place by a holding device. The holding device must be designed so that it presses the screw onto the screwdriver bit 166 and holds it there in position.

[0052] Here too, the sensor 180 is used in Fig. The probing point A shown in section 14 is sought. The probing point corresponds to the screw hole and is defined by the housing for the screw hole (see Fig. 14, reference sign A). The screwdriver 160 must be positioned over the screw hole in the wall box 20. For this to happen, the probe 180 must locate the screw hole. This can be done using a mechanical probe, as exemplified by the wire 300 in Fig. 16 is shown. The probe 180 can reach through the socket 10 to locate the screw hole in the wall box 20 (as shown in Fig. 17 is shown).

[0053] Here too, the probe 180 can be mechanically designed or operate via image recognition. With image recognition, at least one camera or optical sensor is used to locate the probe point A.

[0054] The proposed socket holder could, for example, also be used to carry out the following procedure 280 for mounting a socket 10, as shown in Fig. 28 is shown: Provide a wall box 20 in which no device screws 30 are arranged (step 281); Providing a socket to be mounted 10 onto the wall box 20 (step 282); arranging device screws 30 onto bits 166 of an electric screwdriver 160 integrated into a socket handle 100 (step 283); Positioning the socket handle 100 on and / or in the socket; (step 284) and subsequent Position the socket 10 over the elongated holes of the socket 10; and (step 285) tighten the device screws 30 using the screwdriver (step 286).

[0055] Furthermore, this procedure could also be carried out with a digital spirit level 50, whereby a step of finding a desired orientation of the socket 10 could take place before tightening.

[0056] Although some aspects have been described in relation to a device or system, it is understood that these aspects also constitute a description of a corresponding method, so that a block or component of a device or system can also be understood as a corresponding method step or as a feature of a method step. For reasons of redundancy, a complete description of the present invention in the form of method steps is omitted here.

[0057] In the preceding detailed description, various features were sometimes grouped together in examples to streamline the disclosure. This type of disclosure should not be interpreted as indicating that the claimed examples have more features than are expressly stated in each claim. Rather, as the following claims reflect, the subject matter may consist of fewer than all the features of a single disclosed example. Consequently, the following claims are hereby incorporated into the detailed description, with each claim potentially representing a separate example.While each claim can stand as a separate example, it should be noted that, although dependent claims refer back to a specific combination with one or more other claims, other examples also include a combination of dependent claims with the subject matter of any other dependent claim, or a combination of any feature with other dependent or independent claims. Such combinations are included unless it is stated that a specific combination is not intended. Furthermore, it is intended that a combination of features of a claim with any other independent claim is also included, even if that claim is not directly dependent on the independent claim.
