Claw-like holding part (holding claw) for a drilling, wall or standing bracket for attaching radiators and the like.

The invention relates to a claw-like holding part or holding claw for a drilling, wall or standing console for fastening radiators or the like, whereby the console is provided with a lower holder fastened to a vertical fastening surface, preferably a vertical rail, and an upper holder mounted on a horizontal support arm section of a support arm in an adjustable and, if necessary, lockable manner, whereby the upper holder has at its free end the claw-like holding part and, for example, a U-profile section extending therefrom and enclosing the horizontal support arm section, in the U-web of which an elongated hole is arranged through which a screw passes, whereby the claw-like holding part of the upper holder is mounted in such a way and is provided with such a starting slope that the claw-like holding part of the upper holder can be automatically moved away from the support arm against a counterforce by a radiator or the like moving towards it.

"Such a holding claw is in connection with a

Wall bracket already known from the German utility model G 87 485.2.

In the known arrangement, the holding claw gives way by the entire support arm section tilting about an imaginary axis, which means that the effective angle of the bevel of the claw-like holding part, which is gripped by a radiator bracket, for example, changes with respect to the gripping edge when it is swiveled up. The slope of this bevel therefore becomes steeper as the tilt angle increases and therefore increases the pressure force to be applied by the radiator and at the same time the frictional moment. It can happen that the slope becomes so great when it is pushed up that the arrangement jams and the locking process is prevented. A further disadvantage is the complexity of this design, which not only affects reliability but also makes assembly more difficult.

The object of the invention is to improve the known holding bracket in such a way that it functions more reliably, in particular during the assembly process there is no change in the angle of the slope attached to the radiator or the like, on the other hand the construction is simplified and thus the manufacturing costs are reduced, and in addition the assembly is to be made even easier.

The problem is solved in that the claw-like holding part is preferably displaceably mounted in a preferably U-shaped formation of the horizontal support arm section in such a way that its movement represents a translational movement running perpendicular to the support arm, and that the counterforce is generated by a spring or elastic flag emanating from the claw-like holding part.

This measure ensures that no tipping moment

occurs, but only a translation movement takes place, whereby the desired constant angular alignment of the bevel with respect to the edge of the retaining tab or the like is achieved, provided that this bevel is designed in a straight line. A further advantage is that the support arm section itself remains stationary during the assembly process and its construction can therefore be significantly simpler than is the case with the prior art. Instead, only a holder mounted in it, designed as a plastic part according to claim 2, slides upwards, which has the further advantage that various embodiments are possible that are not possible with the prior art.

According to claim 2, at least the upper holder is a plastic part which is slidably received in a U-shaped metal or plastic part extending from the support arm.

According to claim 3, the counterforce can be formed by a plastic flag which extends in one piece from the plastic part and whose free end rests against the inner web wall of the U-shaped part. This represents a particularly simple and inexpensive embodiment which also has the advantage that it simultaneously forms a soundproofing device.

According to yet another embodiment, claim 4, the plastic tab is placed over a longer curved area of the inner web wall of the U-shaped part, which allows a longer movement path and a largely constant counterforce during the pivoting process and the pushing back of the plastic part by the radiator or its fastening tab or the like.

The free end of the U-shaped part can have a front or

Form a recess, a nose or a wedge which locks into a recess or projection formed by the plastic part sliding in the U-shaped part when the plastic part has reached a position by sliding in the direction of the spring force in which the claw opening of the plastic part grips the seam area and the tab area of a radiator or the edge of another object to be fastened.

It is advantageous if the recess has the shape of a keyhole, whereby the projection locks into the expanded part of the keyhole when the plastic part sliding in the U-shaped part has reached a holding position. However, it is particularly advantageous if, according to yet another embodiment, the locking projection or recess is pressed or held in the locking position by the material thickness of the seam, edge or the like that has penetrated into the claw openings.

This is particularly advantageous because the locking mechanism cannot be removed by unauthorized persons. This is only possible when the entire bracket is removed from the console, for example by unscrewing it. This means that a tool is required to release the locking mechanism.

There is no need for any (possibly subsequent) screwing to lock it in place, as is still necessary with the current state of the art.

It has proven to be particularly advantageous in terms of construction if the run-on slope is formed by a bridge member, the bridge pillar of which starts from the plastic part which slides in the U-shaped part and forms the claw opening and which bridges the free leg of the O-shaped part.

The recess or projection used for locking can also be arranged on this bridge part.

According to yet another development, the claw opening is delimited on its inner end surface by a partial circle that extends over more than 180°, preferably over 210 to 270°, so that a keyhole shape is obtained. The keyhole can form a conical extension at its open end in order to facilitate the insertion of the seam or the like.

The invention is explained in more detail below using embodiments shown in the drawings.

Fig. 1 shows a side view of a console 10

for the

Fastening a radiator 12, the console consisting of a vertical rail 14 with a lower holder 16 for receiving a retaining tab 18 fastened to the radiator 12 and an upper holder 20 which is adjustable and, if necessary, lockable on a horizontal support arm section 22 of a support arm or support bracket 21 fastened to the rail 14, the upper holder 20 having a claw-like holding part 34 at its free end and a U-profile section 24 extending therefrom which encompasses the horizontal support arm section 22, in the U-web 25 of which, see also Fig. 2, an elongated hole 27 is arranged through which a screw 26 passes.

The claw-like holding part 34 of the upper holder 20 is, as will be described in more detail, mounted in such a way that it can be moved and is provided with such a starting slope 52 that the heating element 12 with, for example, a circumferential seam 28, or as here, with an upper fastening part, such as a holding tab 118, presses this holding part 34 against a counterforce in the direction of the arrow 32 and thus away from the support arm section 22 by striking an edge 38 of this holding tab 118 against this inclined surface 52 of the claw-like holding part 34. The counterforce is generated by a projection or flag 30 extending from the claw-like holding part 34, see also Fig. 3 and 4, in that this flag, consisting of relatively thin material molded in one piece with the part 34, deforms in a suitable manner when the part 34 is moved in the direction of the counterforce. A design as shown in Fig. 2 is particularly useful. The claw-like holding part 34 is mounted in a U-shaped formation 36 of the horizontal support arm section 22 or of a component 25 attached to this support arm section 22 in such a way that it can be moved parallel to the legs 50, 54 of this U-shaped formation, whereby the flag 30 is pushed into the U-shaped part by the inner web wall against which it rests.

is bent into an approximately circular shape, thereby creating the counterforce. The plastic material from which the flag 30 is made is so flexible that the flag tries to bend itself straight again. This leads to a counterforce that tries to push the claw-like holding part 34 downwards out of the position shown in Fig. 2, i.e. against the direction of the arrow 32 according to Fig. 1. This leads to the edge 38 of a holding tab 118 or the like initially pushing the claw-like holding part 34 upwards within the U-shaped formation 36 when it strikes the inclined surface 52 until the edge passes the end of the inclined surface or the front surface into the open end of the recess or claw opening or slot 42, whereupon the counterforce of the flag 30 causes the claw-like holding part 34 to be displaced against the direction of the arrow 32 and thus the edge 28 is received in the recess or slot 42.

The U-shaped formation 36 can, see for example Fig. 6, be formed in one piece with the U-profile section 24 and either consist of a metal, for example represent a stamped part made of sheet steel, or be injection-molded from plastic.

The U-shaped formation can be provided with guide devices in the area where the claw-like holding part 34 or (according to Fig. 6) 134 is to slide. However, it can also be guided, for example, within a corresponding groove 46, as can be seen in Fig. 5 in the claw-like holding part 134 shown there.

Alternatively, or in order to improve the guidance even further, the claw-like holding part or 134, starting from the upper end of the run-on slope 52, can form a bridge part 46 according to Fig. 2 or 146 according to Fig. on the opposite side, the bridge pillars 48 or 148 of which, which are supported by the

··

claw-like holding part 34 or 134 or are integral with it, hold the bridge part 46 or 146 in such a way that the free leg 50 of the U-shaped formation 36 is guided and enclosed by the bridge pillars 48, 148, by the bridge part 46, 146 and by the area of the claw-like holding part 34, 134 opposite the bridge part 46, 146.

For even better guidance, the claw-like holding part 34 or 134 can grip the other U-leg 54 of the U-shaped formation 36 with projections 56, 156, see Fig. 4 or Fig. 5, which also extend from the claw-like holding part 34 or 134. If these projections are made relatively wide, as can be seen in Fig. 5, for example, and if the elongated counter surface behind them is taken into account, a very good guide is obtained, which reliably prevents the claw-like holding part 34 or 134 from tilting and thus prevents stiffness when moving the holding part 34, 134 within the U-shaped formation.

One leg of the U-shaped formation, be it the free leg 50 or the other leg 54 of the U-shaped formation 36 attached to the U-profile web 24, can form a projection or recess, nose or wedge, not shown, which is inserted into a recess or projection formed by the claw-shaped holding part 34, 134, see for example the projection 60 in Fig. 4, when the holding part 34 slides in the direction of the counterforce to a position in which the claw opening of the holding part 34 grips the area of the seam 28 of a panel radiator or the upper edge 38 of a tab 118, see Fig. 1, or the edge of another object to be fastened. The recess, into which the projection designated 60 in Fig. 4, for example, runs, can have a keyhole shape. Alternatively, the locking projection or recess can be pressed into the locking position by the material thickness of the seam, edge or similar that has penetrated the claw opening.

or held. For example, the projection 60 shown in Fig. 4 could have the shape of a movable pin that extends into the lumen of the slot 42 with a curved or wedge-shaped front surface and can be pressed outwards there by the penetrating part of, for example, a fastening tab and thus penetrate into a corresponding recess in the U-shaped formation 36 and lock the entire arrangement.

Another locking option is shown in Fig. 7 and Fig. 8, where by inserting a bolt, a piece of pipe, a screw, a plastic pin 62 between the flag 130 resting on the inner web wall of the U-shaped formation 36 and the surface 64 of the claw-like holding part 34 or 134, it is prevented that the claw-like holding part 34, 134 can be moved upwards again from its position in which it is surrounded by the holding tab 118 or the like.

According to Fig. 9, for example, side walls 66 extend from the claw-like holding part 34, which slidably accommodate the U-shaped formation 36 and the flag 30 between them and which have an opening 68 for receiving a locking pin 162 or also a locking screw 162, as can be seen, for example, in Fig. 10, which shows yet another embodiment of a console according to the invention.

Alternatively, the web part of the U-shaped formation 36 can also have a threaded hole 70 into which a locking screw 72 can be screwed from above, which can protrude through a suitably arranged slot or opening (not shown) in the flag 30 and, in its locking position, rests against the surface 64 (Fig. 6) of the claw-like holding part and holds it in position after mounting, for example, a radiator, thus preventing the holding part 34 from being accidentally pushed up. This too

Alternative is indicated in Fig. 10.

In Fig. 10, a U-profile wall rail 114 is provided, in which one leg of a support bracket 74 is inserted into its upper end and mounted on the inner web wall of the U-profile of the wall rail 114, e.g. by means of a screw 76 that is screwed into a threaded hole in the leg 121 or a nut behind it. An elongated hole 78 for a wall rail fastening screw provided above the fastening screw 76 is also arranged in the leg 121. Another elongated hole for another wall rail fastening screw can be seen at 80. The lower end of the rail carries a support bracket 82, one leg 84 of which is attached to the rail 114 by means of a screw 86 via an elongated hole 88 in such a way that it can be moved axially to a limited extent (in order to adapt to the distance between corresponding fastening points of the radiator shown in Fig. 1, for example), and the other leg 90 of which forms a recess for receiving the lower fastening point - if necessary with the interposition of a sound-insulating plastic part 94 of the radiator.

The legs of the rail profile are bent outwards according to the embodiments shown in Fig. and 11 (hat profile) in order to reduce the surface pressure on the wall plane.

Fig. 11 shows a lower holder 182, the shape of which is similar to that of Fig. 1, but as in the embodiment according to Fig. 10, allows a certain axial adjustment using an - not visible - elongated hole 88 in the rail 114 and a fastening screw 86.

There are radiators, see e.g. Fig. 12, that do not have a fastening tab as shown in Fig. 1 at 18,

- 12 -

118 can be seen. However, wall mounting is also possible, provided a special adapter 90 is provided, as can be seen in Fig. 14A and 14B.

The adapter 90 basically has the shape of a double hook in cross-section, whereby the upper hook 91 can be hung over an upper sheet metal edge or seam 93 of the radiator plate 94 that then becomes free when the radiator cover 92 is removed, as shown in Fig. 12 and 14A. A crank 95 adapts the adapter to the radiator plate cross-section. The radiator cover 92 is then put back on, which now holds the adapter(s) 90 in the position shown in Fig. 12. The recessed area 96 of the front end of the lower hook 97 now forms a stop 99 as a replacement for the upper edge 38 of the retaining tab 118 that can be seen in Fig. 1.

The heating element 112 according to Fig. 12 can now be placed with its lower sheet metal edge or seam 193 in the receiving slot of the lower holder 16 according to Fig. 1, 82 according to Fig. 10 and 116 according to Fig. 11. It is then pivoted onto the upper holder as described in Fig. 1 until the edge 96 of the adapter 90 strikes the bevel 52 and pushes the claw-like holding part 34 upwards until the edge 96 engages in the recess 42. If the edge 96 does not strike the bevel 52 correctly, the lower 82 or upper receiving part can be moved axially in the rail direction, for example according to Fig. 10 after loosening the screw 86 or 76, until a suitable impact is ensured. If necessary, an adapter with a different dimension E (Fig. 14A) can also be selected.

A sideways slipping out of the upper (or lower) bracket from the edge 38 is prevented with a tab 118 (or 18)' according to 'Fig. 1 by the kinks that lead to the radiator. With the adapter according to Fig. 14A or B

the edge 99 (formed by the end of the depression 96) serves the same purpose.

By adjusting the distance of the recess 42 from the rail 14 or 114 or the wall plane (by means of the slot 27 according to Fig. 1 or 127 according to Fig. 10), the retaining bracket can be aligned in the assembly position with the edge 96 of the adapter and thus the radiator can be aligned with the wall plane 98.

The adapter 190 shown in Fig. 13A and 13B is designed so that it can be hooked into the cover grid 92 according to Fig. 16. For this purpose, the upper hook area 191 has a larger clear width and the hook end is provided with notches 98 which accommodate the crossbars 113 of the grid 92. The crank 195 is modified and less strong. This adapter is intended for the case that the cover grid 92 is not to be dismantled for the installation of the adapter 190.

Fig. 15A-, 15B show a further adapter 290, which is used if the radiator 212 has, instead of the tabs 18, 118 according to Fig. 1, simple tabs 101 welded onto the outer sheet provided with elongated depressions 100 (e.g. water channels). The space 102 remaining below the tab 101 due to the depression 100 can be used to accommodate the hook 291 of the adapter 290. The width B of the hook 291 corresponds to (or is slightly less than) the width B1 of the depression 100, and the gap width S or the distance of the plane 103 from the plane 104 is selected so that the material thickness of the tab 101 can be accommodated.

The adapter 290 can thus be hung over the flap 101 and then the upper holder of a wall bracket can be "clipped" onto this adapter 290, as shown in Fig. 10, for example.

It is clear that instead of a U-shaped wall rail shown in Fig. 1, 10 or 11, one with an angle profile can also be used, in which one leg of the angle profile rests on the wall and the other leg is directed vertically away from the wall. Upper and lower holding parts 82 and 74 as shown in Fig. 10 can extend from this leg directed away, whether they are integral with the leg or attached to it by means of a screw.

Instead of a wall rail attached to a wall, the standpipe of a stand bracket attached to the floor can also be used to attach the upper and lower brackets (similar to the wall rail in Fig. 10).

The "click" function of the upper bracket or clamp according to the invention can also be used to attach pipe clamps. Radiator covers or radiation shields can also be attached in the same way.

The following should also be mentioned: The dimension A between the upper edge 38 of the upper fastening tab 118 of the radiator 12 (Fig. 1) and the lower edge 138 of the lower fastening tab 18 is referred to in the heating industry as the "α dimension" and is used in general to identify such radiators, regardless of whether fastening tabs 18 are provided according to Fig. 1 or welded tabs 101 according to Fig. 12.

If an adapter according to Fig. 15A, B is now used, this α dimension does not change because the edge 296 is at approximately the same height as the upper end of the slot S. The tab 101 received by the slot S then lies with its upper edge 104 at the same height as the edge 296 of the adapter 290 plugged onto the tab 101.
