Description

There are countless holding devices known from the state of the art with which almost anything can be attached to any location, but I am not aware of any such device that makes it possible to place an object at a height of, for example, 10 meters using, for example, an extendable telescopic extension in seconds, to position and fix it there in one direction, and to remove it from the same device, whereby the objects attached to the holder insert can be supplied with electrical current through the sliding contacts in the holder insert, base support and housing.

The disadvantage of known devices is that if it is necessary, for example, to replace objects from time to time, service them or position them in a different direction, and they are possibly installed in an exposed location, they sometimes have to be dismantled and then reassembled using heavy equipment such as cherry pickers or ladders and tools. The disadvantage is that they take much longer and are expensive; cherry pickers have to be purchased or rented. Ladders pose a higher risk of accidents and usually require a second person to secure them, which in turn incurs costs.

These disadvantages are eliminated by the invention of a device mentioned in the introduction to the description, which makes it possible to place, position and fix a holder insert from a distance. The individual parts which, when combined, result in a functional device are listed below.

Fig.2 describes the housing. It is pushed vertically from above onto the pre-assembled base support (Fig.4) as far as it will go, and you can hear and feel the spring hook tab on the base support (Fig.4.5, 4.9) snapping into place in the spring hook tab seat of the housing (Fig.2.8). When the spring hook tab snaps into place in the seat, the housing is locked vertically upwards, while it is locked or held downwards by the design of the housing and base support shape. Conversely, the housing can be unlocked and removed vertically upwards by pressing with a finger on the spring hook tab (Fig.4.5) through the opening hatch to unlock the spring hook tab (Fig.2.17). The housing can accommodate the holder insert for holding cantilever profiles (Fig.3) and hold it in position in one of the predefined directions. In this position, the holder insert (Fig.3) can also be loaded radially and axially. It is therefore possible to place the holder insert for holding boom profiles (Fig.3) in the housing (Fig.2), to position it in a predefined direction by turning it in the housing and to lock the holder insert in that position. The holder insert can be removed from the housing again by turning it further into a removal position (Fig.2.13). The pin (Fig.2.1) protruding vertically downwards in the housing makes it possible to accommodate the spiral spring part (Fig.8) in a chamber in the holder insert (Fig.3.8), which means that the entire holding device can be kept compact and every millimeter of the entire construction and the individual components is used optimally. If the spring part had been housed in the housing and not in the holder insert, it would have been much more generous and the shaft of the holder insert, where the chamber for the spiral spring is now housed (Fig.3.8), would be empty or solid material, and in any case not shorter, because all components as they are now constructed have been optimally matched to one another in terms of material thickness, diameter and length, with the main focus being on statics. The pin (Fig.2.1) is rounded at its end. This rounding supports the self-centering guided immersion in the inlet opening of the closure cap (Fig.6.8), whereby it should be noted at this point that the play between the outer shell of the inserted holder insert and the inner shell of the housing is so small, i.e. in the range of less than a millimeter, that the main centering has already taken place by inserting the holder insert into the housing. This rounding on the pin is rather secondary to ensure absolutely smooth, sliding and non-jamming insertion and to keep the spiral spring part centered in its chamber through its centering recess (Fig.8.1). Furthermore, the rounding of the pin, which resembles a hemisphere, serves in the centering recess, which is similar to a

Fig.4 describes the base support; it is attached to its intended location, such as to a pipe (Fig.27.14) and then serves as a holder or holding device for the housing (Fig.27.2). Of course, instead of the base support, one could also add through holes for fastening screws or side recesses and passages for hose clamps to the front of the housing. However, attaching the housing Fig.27.2 using the base support Fig.27.4 has a few significant advantages over attaching it directly through the housing using screws or hose clamps. The biggest advantage is that the housing, when used with the base support, can be unlocked by pressing the spring hook tab Fig.4.5 and can be removed within seconds without tools. This means that the housing can be removed if necessary and the base support can be left in its attachment location. Thanks to its flat design, it is hardly noticeable from a distance. Another advantage is that the circumferential profile Fig.4.8 on the base support, which engages the profile of the housing Fig.2.2, can absorb the resulting weight forces over a larger area and in a more distributed manner than would be the case with hose clamps, for example. Hose clamps for outdoor use, usually V2A, could cause corrosion on the less noble metal with a galvanized pipe and acid rain, and there are also many fastening points where hose clamps are not suitable, such as on a house facade. Fastening using screws through the housing has the disadvantage compared to the base support version that the housing can only be removed with a corresponding amount of effort and a tool. Furthermore, the housing would have to be constructed much more generously in order to accommodate the screws and screw heads. The

Fig. 5 describes the positioning mandrel. Its shaft (Fig.5.2) is inserted or driven into the front end of an extension profile which has a through hole (Fig.13.1) and is additionally fixed there against axial tension and radial twisting using a bolt (Fig.11). With the extension profile (Fig.13) and attached positioning mandrel (Fig.5), it is possible to place the holder insert (Fig.3) in the housing (Fig.2) from a distance, to position it there or to remove it from the housing. The positioning mandrel transfers the radial and axial forces exerted by the user due to its special shape, which engages with the counter shape of the holder insert with only a small amount of play and a clamping-locking function. Since the holder insert can only be turned into the removal position and then removed using the positioning mandrel provided for this purpose, the mandrel could also be given the additional function of a key (theft protection). The geometry of the mandrel (Fig.5.5, 5.7, 5.6) as well as that of the counter-form in the holder insert were designed exclusively with conical curves and a funnel-shaped opening (Fig.3.7), which makes it possible to thread it from a distance. The radial position of the extension profile with positioning mandrel can be in any position from 0-360° when inserted into the holder insert. The positioning mandrel including the extension profile automatically aligns itself to the counter-form when inserted into the holder insert thanks to the slanted, almost pointed surfaces (Fig.5.5, 5.7). Once the mandrel tip (Fig.5.7) has been threaded into the funnel of the holder insert (Fig.3.7), the positioning mandrel with the extension profile can be pushed axially and radially practically blindly into the counter-mold (Fig.3.12) until it stops and the tips (Fig.5.1) click into place, in order to then position the holder insert or remove it from the housing. The lower end of the positioning mandrel shaft (Fig.5.2) is slightly touched (Fig.5.9), which makes it easier to attach to the extension profile. In order to achieve the best possible and permanently firm fit, the mandrel is driven into the respective extension profile using a soft-face hammer until it stops (Fig.5.11), whereby the webs (Fig.5.8) are larger by a factor of x than the nominal inner diameter of the

As can be seen in Fig.6, the closure cap is part of the holder insert for holding boom profiles (Fig.3), and has been fully integrated into the design. Due to the design, the holder insert (Fig.3) was constructed in two parts, so it is possible to insert a spiral spring (Fig.8) into the chamber (Fig.3.8) and then press the closure cap on to hold it in a pre-tensioned state. After inserting the spiral spring (Fig.8) into the chamber provided for it (Fig.3.8) in the holder insert (Fig.3), it is automatically held centrally by the seat (Fig.3.9) and the already small gap that exists between the spiral spring and the cylindrical cavity (Fig.3.8). The closure cap is then placed with its inner dome (Fig.4.9) on the dome-shaped head of the spiral spring (Fig.8.2) and pushed against the spring force of the spiral spring (Fig.8) in an axial direction towards the holder insert.

Fig.7 describes the push button which is required to unlock the boom profile (Fig.12) and remove it from its holder (Fig.3.25). The push button is part of the locking mechanism which consists of three basic components which must be built into the holder insert or plugged in for the locking and unlocking to work. 1. The locking part with the locking pin (Fig.10), 2. the shaped spring part (Fig.9), and 3. the push button (Fig.7) for triggering the unlocking. Once the locking part (Fig.10) and shaped spring part (Fig.9) are placed in the space provided in the holder insert (Fig.3.26), the push button (Fig.7) can be inserted. This is done by positioning it and pressing it in as far as it will go. Once the spring tabs have engaged, the push button can no longer be removed without breaking off the spring tabs (Fig.7.1). The push button is pushed in against the spring force of the shaped spring part (Fig.9) until it stops (Fig./7.6) (Fig.3.17). The resulting stroke movement is transmitted through the push button shaft (Fig./.4) and the contact points (Fig.7.7/, 7.8) to the movable locking part with locking pin (Fig.10.3) pre-tensioned by the shaped spring part. The locking part can move back the required stroke against the spring force of the shaped spring part (Fig.9) and

Fig.8 describes the spiral spring part, which has the task of holding and locking the holder insert (Fig.3) with its tabs (Fig.3.20) in the holding seat recesses (Fig.2.5) of the tabs (Fig.2.6) in the housing (Fig.2) radially and axially in position against a spring force. This is achieved by engaging the holder insert holding tabs (Fig.3.20) in the housing holding seat tabs (Fig.2.6), whereby the side cheeks (Fig.2.4) prevent the holder from turning radially in the housing and the holding seat recesses (Fig.2.5) push the holder insert axially downwards in the housing so that the holder insert is held in the housing. The holder insert can, however, be pushed upwards in an axial direction against the spring force in order to push the holding tabs (Fig.3.20) lower edge (Fig.3.5) over

Fig.9 describes the shaped spring part which has the task of providing sufficient spring force for locking the boom profile and sufficient compression of the spring for the unlocking stroke in a limited space (Fig.3.26). After the locking part (Fig.10) has been inserted into the holder insert, the shaped spring part is inserted with the springy part (Fig.9.6) first and the curve (Fig.9.4) of the round surface in the recess (Fig.3.26) until it clicks into place. When it clicks into place, the short tab with a recess (Fig.9.2) which is tautly springy due to the material recess (Fig.9.3) is pushed over the curve of the axis of the locking part (Fig.10.1). The locking part and shaped spring part are now held firmly in position and can only be removed with the help of tools. For this purpose, a metal pin bent 90° at the front end can be threaded into the hole (Fig.9.1) and the shaped spring part can be pulled out. The shaped spring part is already sufficiently pre-compressed when inserted, whereby the highest point of the shaped spring (Fig.9.6), which is at the level of the locking pin (Fig.10.3), presses the locking part against the flat side of the recess (Fig.3.26). The locking pin now remains in its recess with sufficient spring pre-tension (Fig.3.14). This recess relieves the locking part enormously and the short projection of the pin which engages in the hole of the boom profile (Fig.12.2) can absorb very high axial forces, whereby the radial forces are additionally or mainly absorbed by the shape of the profile (Fig.12.1) and the counter-shape of the holder itself (Fig.3.29). The force generated by the spring

Fig.10 describes the movable locking part with the locking pin (Fig.10.3). It allows the boom profile (Fig.12) to be held in position radially and axially in the receiving opening of the holder insert (Fig.3.25) and to be locked or unlocked for the removal of the boom profile. The locking part (Fig.10) is part of the locking mechanism, which consists of 3 (with the holder insert body 4) basic components that must be installed or plugged into the holder insert after production so that the locking and unlocking functions work. 1. the locking part with the locking pin (Fig.10), 2. the shaped spring part (Fig.9) and 3. the push button for releasing the lock (Fig.7). The locking part (Fig.10) is pushed with the pin first into the recess for the locking part and shaped spring part (Fig.3.26), with the curve on the underside of the locking part (Fig.10.5) facing the curve in the recess for the locking part and shaped spring part (Fig.3.26). In the existing example, it is even the case that, similar to a coding, the locking part cannot be inserted into the recess (Fig.3.26) the other way round. This is partly due to the low overall height that made this design necessary. When fully pushed in, the locking part with the pin (Fig.10.3) clicks or falls into the recess in the holder insert (Fig.3.14). The shaped spring part (Fig.9) and then the push button (Fig.7) can now be inserted. Basically, all parts of the quick-change holder were designed so that assembly takes place without tools by inserting and clipping in. The highest point of the shaped spring (Fig.9.6) now presses the locking part against the flat side of the holder insert, at the level of the locking pin (Fig.10.3), the one with the recess for the stabilizing web and the pin hole (Fig.3.14), so that the pin now locks the hole with a pre-tensioned spring and prevents radial and axial movement of the boom profile. Due to the one-sided bevelled construction of the pin, the boom profile can be inserted without pressing the push button. The bevelled design of the pin allows the boom profile to be pushed against the spring force when inserting the pin.

Fig.11 describes the bolt; it is used to fix the positioning mandrel in the extension profile. Of course, you could attach a thread to the positioning mandrel and extension profile and in this way create a positive connection, or using adhesive. In any case, the easiest way is to drill a through hole in the extension profile. In series production, use an appropriate drilling template. The bolt and the hole in the positioning mandrel (Fig.5.10) can be manufactured additively without any noticeable additional effort. The diameter of the bolt is only minimally smaller than the recess on the shaft of the positioning mandrel (Fig.5.10), and is clamped by the webs (Fig.5.3) in the hole in the positioning mandrel. The bolt is driven into the recess using a hammer. The bolt is adapted to the radius of the extension profile at both ends and is fully rounded off with it.

Fig.12 Describes the boom profile which is inserted with the recess for the locking pin (Fig.12.2) first into the holder insert receptacle (Fig.3.25) until the locking pin (Fig.10.3) engages in the recess of the extension profile (Fig.12.2) and the boom profile is locked axially against tension and radially against twisting. The boom profile has at least one recess (Fig.12.2) at the level of the recess for the locking pin in the holder insert (Fig.3.14). The boom profile can be made from various materials, with aluminum, GRP, carbon or stainless steel being ideal for this application due to their stability and weather resistance if the holding device is to be used outdoors. The boom profile can be round, oval, triangular, square, polygonal or customer-specific; the holder insert and the profile holder in the holder insert can be adapted to the boom profile. Likewise, the recesses in the boom profile (Fig.12.2), in the holder insert (Fig.3.14) and the locking pin itself (Fig.10.3) can be round, oval, square or have a different shape. A round boom profile with an internal or external thread on the base is also conceivable, either directly on the profile or inserted into the profile, whereby instead of the locking mechanism (push button, locking part, shaped spring part) there is a corresponding counter thread inside the holder insert holder. The web in the profile (Fig.12.3) is intended as a coding for a round profile so that you do not have to search for the recess for the locking pin (Fig.12.2), since the tube can only be inserted in one position. Furthermore, depending on the design of the web, it also provides additional stabilization for the boom profile. The web takes over the radial locking in the counter form in the holder insert (Fig.3.29) and relieves the
