Description

[0001] The invention relates to a tool from the construction industry, in particular a hand tool for installing flush-mounted boxes in masonry.

[0002] Various tools for installing flush-mounted electrical boxes are known from the current state of the art. These tools are generally not universal but are only suitable for specific box types, either for single boxes or specific multiple combinations, for example, 2, 3, 4, or 5 boxes in a row. A further disadvantage is that attaching the box(es) to the tool is complicated and time-consuming. Subsequently, not only is precise positioning and alignment of the box(es) in the masonry difficult due to the design and function of the tools, but also, and especially, removing the box(es) or the tool without unintentionally displacing the box(es). In addition, adapting to different plaster thicknesses is often only possible to a limited extent. These disadvantages mean that installing flush-mounted electrical boxes with existing tools is error-prone, time-consuming, and inconvenient.

[0003] One object of the present invention is therefore to provide an improved, readily usable installation aid for inserting and aligning flush-mounted boxes in a masonry wall.

[0004] This problem is solved by a junction box inserter according to claim 1. The junction box inserter for flush-mounted boxes, suitable for both single boxes and multiple boxes, comprises a holding device for holding one or more flush-mounted boxes, wherein the holding device has a number of holding elements that can be brought into an operative connection, in particular an engagement, with the flush-mounted box(es). The junction box inserter also comprises an actuating device for preferably simultaneously releasing the operative connection of the holding elements, in particular for releasing the engagement, preferably with a single actuating path, with a single movement and / or in a single operation.

[0005] The junction box setter is flexibly adaptable to different arrangements of flush-mounted boxes, both single boxes and various multi-box combinations, and therefore offers significantly greater versatility compared to conventional junction box setters. It is universally applicable to all common flush-mounted boxes and combinations, including special boxes such as dual-chamber boxes (network boxes). This significantly expands its range of applications compared to existing tools.

[0006] Attaching the junction box(es) to the junction box setter is straightforward, requiring only one movement and taking only a short time. The setter's design and functionality not only allow for precise and secure positioning and alignment of the junction box(es) in the masonry, but also ensure that the junction box(es) remain in the desired position even after removal of the tool.

[0007] Furthermore, the can setter according to the invention allows for quick and easy adaptation to different plaster thicknesses.

[0008] In summary, the socket setter enables the error-free, quick, and convenient installation of flush-mounted sockets. The invention ensures simple, reliable, and precise alignment of the sockets, meeting the requirements of various construction and renovation situations.

[0009] Advantageous embodiments of the invention are specified in the dependent claims or can be seen from the following description and / or the accompanying figures.

[0010] According to one embodiment of the invention, the functional connection formed by the retaining elements of the retaining device with the flush-mounted boxes is a force-fit and / or form-fit, releasable connection, in particular a plug-in, clamp, snap or latch connection.

[0011] According to one embodiment of the invention, the can setter comprises a distance adjustment device for one or more of these retaining elements, which distance adjustment device is designed to adjust the lateral distance of the retaining elements.

[0012] The retaining elements are preferably held in bearings described in more detail below. To adjust the lateral distance of the retaining elements, these bearings are designed to be positionally adjustable, in particular such that the bearings, preferably individually and independently of one another, are arranged to be linearly displaceable on a rail system of the base body of the can inserter.

[0013] According to one embodiment of the invention, the actuating device is designed to preferably simultaneously release the operative connection of the retaining elements regardless of the lateral distance of the retaining elements.

[0014] According to one embodiment of the invention, the actuating device is configured such that the retaining elements are held in a mounting position when the actuating device is not actuated. In this mounting position, a number of flush-mounted boxes can be attached to the retaining elements of the mounting device of the box setter, such that the flush-mounted boxes can be inserted into a wall opening in masonry using the box setter and aligned there to reach their final mounting position. According to this embodiment, the flush-mounted boxes are simply attached to the box setter and held in place on it.

[0015] According to one embodiment of the invention, the retaining elements are mounted in an axially displaceable manner and the actuating device is designed such that the retaining elements can be moved from their mounting position into an axially displaced actuating position different from the mounting position, in which actuating position the operative connection of the retaining elements is released.

[0016] By releasing the operative connection, preferably simultaneously, the flush-mounted boxes previously held by the box installer are immediately released without altering their previously set position or orientation. In other words, releasing the operative connection has no effect whatsoever on the previously achieved final mounting position of the box(es). This represents a particularly advantageous improvement compared to conventional box-installing tools.

[0017] According to one embodiment of the invention, the retaining elements are mounted in bearings so as to be axially displaceable. These bearings also serve as axial guides for the retaining elements, thus preventing tilting or jamming of the retaining elements.

[0018] According to one embodiment of the invention, the actuating device is designed such that the retaining elements can automatically return from their actuating position to their mounting position when the actuation ceases.

[0019] The automatic return preferably occurs due to a spring load on the holding elements, which spring load is caused by one or more spring elements of the actuating device acting on the holding elements.

[0020] Once the retaining elements are back in their mounting position, the next flush-mounted box or multi-gang box can be immediately placed on the box setter. No additional preparation steps, such as resetting the box setter for another box, are necessary.

[0021] According to one embodiment of the invention, the actuating device has a handle for actuating the actuating device. This handle is preferably integrated into a handle of the can setter such that the handle can be actuated without releasing the handle.

[0022] Preferably, the can inserter has a single, centrally located handle. The advantageously ergonomically designed handle includes a push button, preferably integrated into the handle, for actuating an operating device. The push button is preferably arranged such that it can be actuated while the handle is being held, i.e., without releasing the handle. No repositioning of the grip or additional actions are required to operate the handle.

[0023] According to one embodiment of the invention, the handle is designed as a push button and integrated into the grip of the handle. The push button is arranged in and integrated into the grip of the handle. Preferably, the push button is guided in a push button guide within the handle, so that tilting or jamming is prevented.

[0024] According to one embodiment of the invention, the actuating device can be operated manually, as described above. Alternatively, the actuating device can be operated by a motor, preferably an electric motor. The push button integrated into the handle of the can inserter is then preferably a push button switch for switching the electric motor drive of the actuating device. As an alternative to a push button switch, another type of switch for switching the electric motor drive of the actuating device can also be arranged at a suitable location on the can inserter.

[0025] According to one embodiment of the invention, the box setter comprises a stop, wherein the holding device is designed to hold the number of flush-mounted boxes in a stop position, in which stop position the flush-mounted boxes attached to the holding elements strike the stop of the box setter, particularly when inserting the flush-mounted boxes into the wall opening of the masonry.

[0026] According to one embodiment of the invention, the junction box setter comprises a positioning device for positioning one or more flush-mounted boxes in the stop position, wherein the positioning device has a number of positioning elements, the positioning elements holding the flush-mounted box(es) in the stop position when the holding elements of the holding device are brought into operative contact with the flush-mounted box(es) and / or when the flush-mounted boxes are inserted into the wall opening of the masonry. The positioning elements are designed such that they limit the movement of the flush-mounted box(es) transversely to the stop.

[0027] Preferably, several, preferably four, positioning elements are provided centrally at the stop, projecting from the stop, and are designed and arranged such that, in the stop position, they are positioned directly adjacent to an outer edge and / or an inner edge of the flush-mounted box(es), both in the case of a single box and in the case of multiple boxes. When using two retaining pins, the positioning elements are preferably arranged centrally between them.

[0028] The positioning aid for the flush-mounted box(es) achieved in this way supports the mounting of the boxes based on the push-on mechanism and prevents the flush-mounted box(es) from being pushed out of place when inserting and / or pressing the flush-mounted box(es) into the wall opening.

[0029] According to an alternative embodiment of the invention, the positioning device is designed as a fixing device for fixing one or more flush-mounted boxes in the stop position, wherein the fixing device has a number of fixing elements, wherein the fixing elements automatically enter into an operative connection with the flush-mounted box(es) when the retaining elements of the holding device are brought into operative connection with the flush-mounted box(es) and / or when the flush-mounted boxes are inserted into the wall opening of the masonry, and wherein the operative connection of the fixing elements is automatically released when the operative connection of the retaining elements is released.Preferably, the fixing elements protruding from the stop are designed and arranged in such a way that, both in the case of a single box and in the case of a multiple combination, a holding coupling of the fixing elements with the flush-mounted box(es) can be established by the fixing elements engaging the outer edge and / or the inner edge of the flush-mounted box(es) in order to fix the flush-mounted box(es) by forming a force-fit and / or form-fit connection, in particular a clamping connection, between at least two of these fixing elements.

[0030] According to one embodiment of the invention, the positioning elements of the positioning device or the fixing elements of the fixing device are not designed to be fixed in position or rigid, but rather – in the same or a similar way as the holding elements of the holding device – are movable in position, either together with the holding elements or separately from them, from a mounting position in which they limit the movement of the flush-mounted boxes transversely to the stop, to an operating position in which they do not fulfill any movement-limiting or positioning-assist function.

[0031] According to one embodiment of the invention, the holding device has at least two, preferably exactly two, parallel-aligned holding pins as holding elements for holding one or more flush-mounted boxes.

[0032] According to one embodiment of the invention, the retaining pins for holding the number of flush-mounted boxes are designed in such a way that they can be inserted into fastening openings, in particular screw bosses, of these flush-mounted boxes.

[0033] Preferably, the junction box setter is suitable for all flush-mounted boxes standardized according to DIN 49073. Flush-mounted boxes according to this standard have standardized mounting distances (60 mm), with the mounting holes having an M3.5 mm thread. Preferably, the junction box setter is designed to match the dimensions of the flush-mounted boxes specified by the aforementioned standard with regard to the adjustable lateral distances of the mounting elements and the dimensions of the mounting elements, in particular the diameter of the mounting pins. Compliance with this standard then ensures standardized installation and the possibility of handling multiple combinations with the junction box setter.

[0034] According to one embodiment of the invention, the retaining pins are axially coupled and the actuating device is designed for the synchronous axial retraction of the retaining pins from the mounting openings of the flush-mounted boxes while maintaining the lateral distance of the retaining pins.

[0035] According to one embodiment of the invention, the distance adjustment device comprises a device for individually or jointly displacing the retaining pins linearly transversely to the pin axis.

[0036] The lateral spacing of the retaining pins is preferably adjustable so that the pin spacing corresponds (by standards) to the spacing of a number of mounting holes in the flush-mounted boxes. Particularly precise adjustment of such a well-defined lateral spacing of the retaining pins is achieved by using ball detents or alternative locking mechanisms in the spacing adjustment device to secure the positions of the adjustable bearings of the retaining pins.

[0037] According to one embodiment of the invention, the actuating device is designed such that the operative connection of the retaining elements can only be released if the bearings which are linearly displaceable on the rail system of the base body of the can setter are in their predefined positions, which are ensured by ball detents or alternative locking mechanisms and correspond to precisely defined lateral distances of the retaining pins.

[0038] According to one embodiment of the invention, the distance adjustment device can be operated manually. Alternatively, the distance adjustment device can be operated by a motor, preferably an electric motor, wherein a switch for switching the electric motor drive of the distance adjustment device is provided at a suitable location on the can inserter.

[0039] According to one embodiment of the invention, the can setter comprises a number of spacers for placing the can setter on the masonry.

[0040] The spacers preferably have particularly large (wide) bearing surfaces to ensure secure support even in wide wall chases and uneven masonry. This reliably prevents the bearing surfaces from slipping into installation or electrical chases, or similar features.

[0041] According to one embodiment of the invention, the box setter comprises an adjustment device for adjusting the working distance of the box setter to the masonry for different plaster thicknesses, preferably from 0 mm to at least 20 mm, in particular such that both a surface-mounted installation and a flush-mounted installation of the flush-mounted boxes is possible, wherein the adjustment device is designed to adjust the distance of the bearing surfaces of the spacers relative to the stop.

[0042] The ability to adapt the socket setter to different plaster thicknesses, including flush installations from 0 mm, is particularly advantageous for renovations or conversions of old buildings.

[0043] According to one embodiment of the invention, the adjustment device comprises guides for the spacers, in particular with guide grooves or rails as guide elements. Preferably, two spacers are provided, each attached to the end of the can inserter, wherein each of these spacers is guided in two spaced-apart guides, in particular such that an accidental skewed arrangement of a spacer is precluded by design due to the double guide.

[0044] Preferably, the spacers are fixed to the guide elements with screws so that they cannot be pushed out of place when the flush-mounted boxes are inserted into the masonry.

[0045] Preferably, the spacers are detachably connected to the base of the can inserter so that they can be easily replaced if damaged. In a particularly simple case, the spacers can simply be removed from the guides of the adjustment mechanism once the screws are loosened.

[0046] Particularly precise adjustment of the working distance is achieved by the fact that the adjustment device includes ball detents or alternative locking mechanisms to provide defined distances, which, with screws loosened and defined adjustment distances maintained, serve to precisely adjust the spacers in the guides.

[0047] According to one embodiment of the invention, the adjustment device can be operated manually, as described above. Alternatively, the adjustment device can be operated by a motor, preferably an electric motor, wherein a switch for switching the electric motor drive of the adjustment device is provided at a suitable location on the can inserter.

[0048] To assist in the correct alignment of the flush-mounted box(es) during insertion and alignment to reach its final mounting position, the box setter according to one embodiment of the invention includes a number of spirit levels and / or alignment or centering marks.

[0049] Precise alignment of the junction box setter is ensured by spirit levels arranged in different orientation planes, regardless of the direction in which the setter is held. Preferably, the junction box setter has four spirit levels attached at suitable locations, arranged in pairwise orthogonal orientation planes; preferably, one spirit level is attached to each side of the setter. This allows for simple and correct horizontal and vertical alignment of the junction box setter, and thus of the flush-mounted box(es), regardless of how the setter is held or its position. This is advantageous compared to known tools with a spirit level attached to only one side.

[0050] Several alignment or centering marks, preferably in the form of centering tips, preferably in pairs, can be advantageously used to position the flush-mounted box(es) precisely on the desired or marked axis. It has proven particularly effective to attach the alignment or centering marks to the two bearings of the retaining pins, especially to those bearing parts that are slidably guided on the base of the box inserter.

[0051] While the retaining elements, in particular the retaining pins, as well as the other components of the box installer that absorb forces when holding the flush-mounted boxes, especially rail and guide elements, are preferably made of steel or a similar, particularly rigid material so that they cannot be bent or broken when the box installer is used on the construction site, the spacers and other components that do not perform force-absorbing functions, such as elements of the dirt-sensitive parts of the box installer, are preferably made of plastic to save weight. This applies in particular to parts of the box installer's housing that protects the holding and operating device from dirt.

[0052] An embodiment of the invention is explained in more detail below with reference to the drawings. These show: Fig. 1 a can setter with holding elements that are in a mounting position (side view), Fig. 2 the can setter from Fig. 1 in a perspective view diagonally from below showing a multiple combination of three flush-mounted boxes, before establishing a functional connection, Fig. 3 a can setter with retaining elements which are in an actuating position, so that the actuating position is released (side view), Fig. 4 the can setter Fig. 3 in a perspective view obliquely from below, Fig. 5 the can setter Fig. 2 in a perspective view obliquely from above, with the casing partially removed to illustrate the internal construction, Fig. 6 a box setter, the holding elements of which are designed to establish an effective connection with a single flush-mounted box, Fig.7 a box setter whose holding elements are designed to create an effective connection with a multiple combination of five flush-mounted boxes.

[0053] All figures do not show the invention to scale, only schematically and with its essential components. Identical reference numerals correspond to elements with the same or comparable function.

[0054] The socket setter 1 for flush-mounted sockets 2 has an essentially H-shaped form, with an elongated base body 10, on which a handle 12 is attached in the middle.

[0055] A holding device 3 of the box setter 1, which serves to hold the flush-mounted boxes 2, comprises two bearings 8 attached to the base body 10 with holding pins 4.

[0056] The lateral distance 7 of the retaining pins 4 can be manually adjusted using a distance adjustment device 6. For this purpose, the distance adjustment device comprises a rail system with two guide rails 9, along which the bearings 8 can be individually moved. Each bearing 8 is guided on both guide rails 9 as well as on stop rails 27 of the base body 10 of the junction box inserter 1. Ball detents (not shown) are installed in the bearings 8, which engage in designated detent recesses (not shown) in the rails 9 to position the bearings 8 so that the retaining pins 4 have predefined lateral distances from each other, corresponding to the distances between the screw bosses 17 of the flush-mounted box(es) 2 to be held. This allows the positions of the retaining pins 4 to be adapted to the respective dimensions of single boxes and multiple combinations consisting of interconnected single boxes, fixing them stably and with repeatable accuracy.

[0057] The bearings 8 with the retaining pins 4 are designed such that flush-mounted boxes 2 of different designs and combinations can be securely held by simply pushing them into place. The retaining pins 4 are inserted into the screw bosses 17 of the flush-mounted box(es) 2. The flush-mounted boxes 2 then rest with their box edges 26 against a stop 14 of the box inserter 1. The stop 14 is formed by a pair of stop rails 27, which extend essentially over the entire length of the box inserter and form part of the H-shaped web of the base body 10. Another part of the stop 14 is formed by the undersides 28 of the bearings 8. For this purpose, these undersides 28 run in a plane with the stop rails 27. By attaching the flush-mounted boxes 2 to the retaining pins 4, the boxes 2 are held securely, since the dimensions of the retaining pins 4 are appropriately matched to the dimensions of the screw bosses 17.Manual or additional screwing of the flush-mounted box(es) 2 to the box setter 1 is not required.

[0058] The junction box setter 1 with the attached flush-mounted boxes 2 can then be inserted into the desired wall cavities (not shown) using suitable fastening material (not shown) and aligned as usual. The flush-mounted boxes 2 can be positioned particularly quickly and easily on the desired and marked axis using the centering tips 25 attached to the bearings 8 on both sides. Spirit levels 24, located on all four sides of the base body 10, are used to align the junction box setter 1.

[0059] A positioning device 15 with four positioning elements 16 in the form of circular segment-shaped ribs arranged centrally on the stop 14 and projecting from the stop 14 ensures that the flush-mounted boxes 2 cannot be deformed by inserted fasteners when being inserted into the masonry. This is achieved by arranging the positioning elements 16 directly adjacent to the outer edge and / or the inner edge of the flush-mounted box(es) 2 in order to limit any movement of the flush-mounted box(es) 2 transversely to the stop 14 between at least two of these positioning elements 16, regardless of how many flush-mounted boxes 2 are held by the box installer 1.

[0060] Once the flush-mounted boxes 2 have reached their final mounting position, the box installer 1 must be able to release them. The flush-mounted box(es) 2 are released by an actuating device 5 integrated into the base body 10, which is actuated by a push button 11 integrated into the handle 13 of the handle 12 of the box installer 1.

[0061] The actuating device 5 comprises one or more spring elements (not shown) acting on the retaining pins 4. The actuating device 5 acts simultaneously on both bearings 8, regardless of their position. When actuated, the retaining pins 4 are retracted synchronously against the spring force of the spring elements in the bearings 8, so that the retaining pins 4 disengage from the screw bosses 17 and the flush-mounted boxes 2 are released. The previously set position and orientation are fully maintained, so that the flush-mounted box(es) 2 are not unintentionally moved or rotated when released.

[0062] When the push button 11 is actuated, the guide rails 9 are moved upwards away from the stop 14 via a suitable transmission mechanism located within the handle 12. This causes the first bearing elements 30, which are engaged on the rails 9 and carry the retaining pins 4, to also move upwards. This means that the retaining pins 4 move out of the screw bosses 17 along their pin axes 18, while the second bearing elements 31, which are guided on the base body 10, specifically on the stop rails 27, and on which the centering tips 25 are attached, remain in their position. Releasing the retaining pins 4 from the flush-mounted boxes 2 is accomplished with a single actuation, a single movement, and in a single operation.

[0063] Movement of the guide rails 9 with the first bearing elements 30 guided thereon, in order to release the operative connection of the retaining pins 4, is not possible if the first bearing elements 30 are not precisely engaged on the rails 9. This is because only in these predefined positions do recesses 32 provided in the housing 29 of the base body 10, spaced at the intervals corresponding to the detents, allow the first bearing elements 30 to move upwards away from the stop 14. If the bearing elements 8 are not precisely in the predefined positions along the guide rail 9, the base body 10 acts as a lock for the actuating device 5.

[0064] After the functional connection is released and the flush-mounted box(es) are thereby freed, the box inserter 1 should be returned to its ready-to-use initial state. This is achieved simply by releasing the push button 11. Upon releasing the push button 11, the actuating device 5 is automatically reset, so that the retaining pins 4 are moved into their mounting position and new flush-mounted boxes 2 can be attached. The automatic return of the push button 11 and the retaining pins 4, along with the transmission mechanism, occurs due to the spring tension exerted on the actuating device 5 by the spring elements.

[0065] At both ends, the junction box setter 1 has adjustable spacers 19, which together with the base body 10 form the aforementioned H-shape. The spacers 19 have particularly large contact surfaces 20, which reliably prevent slippage into masonry or electrical chases.

[0066] With the aid of an adjustment device 21, the distance 22 of the bearing surfaces 20 of the spacers 19 relative to the stop 14 can be adjusted incrementally to different plaster thicknesses, starting at 0 mm. For this purpose, the adjustment device 21 includes guides 23 for the spacers 19. The spacers 19 can be easily adjusted to the correct plaster distances by means of ball detents (not shown) also provided in the guides 23.

[0067] The design of the base body is ergonomic, allowing the user to comfortably hold the can setter 1 with one hand using the handle 12. The locking pins 4 can be operated without repositioning the hand holding the handle by simply pressing the push button 11 upwards into the handle 13.
