Abstract

RADIATOR MOUNTING

Abstract of the Disclosure A radiator mounting for holding a radiator on a wall has a plate supportable with a wall plug and a clamping piece which can be braced by a screw towards each other and in the process from various directions against tubes or fins of the radiator. The clamping piece comprises two side members connected by a bridge.
The screw extends through a hole in the bridge, there being a spreader arranged on the screw between the side members such that when the screw is tightened, the side members spread outwards away from each other up against the tubes or fins of the radiator. To make the spread-ing action more effective, the spreader has a through hole for the screw, as well as a longitudinal slot in its central plane between the two side members, so that as the head of the screw is drawn into the spreader when the screw is tightened, the spreader is forced apart.

Description

~ ~ 56~72 Specification ~; adiator mountin~

The invention relates ts a radiator mounting com~ri~ing a plate which ls supportable with or attachablP to a wall plug and a screw extending through the plate and through a clamping piece, said clamping piece having two spreadable side members connected by a bridge, between said side members there being a spreader arra~ged on th~ screw such that when the screw is tightened, the side members spread outwards away ~rom each other up against adjacent radiator tubes or fins. Such ~ radlator mounting is k~own ~rom German patent 2 632 119.

In an embodiment of the known radiator mountlng, the screw of the countersunk kind has a truncated-cone head~ which penetrates between said side members when th~ ~crew is tightened and ser~es as a spreader. In this embodiment, the attainable spread of the s~de members depe~ds on the diameter o~ the screw head. Thi~
~0 diameter mu~ be sel~cted to be o~ maxlmum pos~ible 9ize~ SQ
tha~ said side m2mbers can be ~pread as ~ar apart as po~ible ~, betw~en r~dia~or tub~s; on ~e other han~, howev~r, the diameter o~ ~he h~ad must be small enough to enable the radiator mounting ~ill to be inserted be-tween radiator tubes which ~re clo~e ~Og~ther.

y~, ' The ob je ct o~ the lnYention i~ to deve:lop the radiator mountlng of the earlier-mentioned type in such a manner that it can still be lnserted be-tween radlator tubes which are close together and yet also enables the ~ld side members to be ~pread d~pendably between radiator tubes which are consid~rably further apart.

This object is achieved in the invention by means of a spreader having a through hole, in which the screw can be moved longitud-inally, as well as a longitudinal slot in it~ central plane 1Q between the side members at the end away from the plate, said - spreader being caused to spread when the screw is tightened as the screw head penetrates into the spreader~

In the unspread condition 7 the spreader need not be thicker than the diameter of the screw head and can even be narrower.
The screw head, which is preferably conical, does not act direct-ly on the sid~ members ~hen the screw is tightened but penetrates into the spreader, causing the latter to spread out and press the side members apart. In the process, the spreader c~n attain a thickness considerably greater than its original thickness and than the diameter of the screw head.

In a preferred embodiment of the invention, the through hole in the spreader has a conical enlargement matching -the head of the screw at its end away from the plate. ~his confipuration makes it easier to introduce the head of the screw illtO the spreader a~d prevents excessive pressures per u~it area.

I~ the side members, as in the subject matter of the patent, h~ve a U-section in a cross cut -through the screw, it is an ~dvantage i~ in accordance wi-th a developmeIlt of ~he invention~
~th~ spreader ~l~S a rectangular cro~s section ma-tchin~ the U scctl~
of: the $ide members~ I~ thi~ way, the spreader is guided dependably between ~atd side members, on -the one hand, and stiffens them particularly ~f~ectivelyt on the o~ther hand.

1 1S6~7 2 - 2a -Thus, according to one aspect of this invention there is provided a radiator mounting comprising a plate which is supportable with or attachable to a wall plug, a clamping piece and a screw extending through the plate and through the clamping piece, said clamping piece having two spreadable side members connected by a bridge, between said side members there being a spreader arranged on the screw such that when the screw is tightened, the side mem-bers spread outwards away from each other up against adjacent radia~or tubes or ~ins, characterized in that the spreader has a through hole, in which the screw can be moved longitudinallyl as well as a longitudinal slot in its cen-tral plane between the two side members at the end away from the plate, said spreader being caused to spread when the screw is tightened as the head of the screw penetrates into the spreader.

1 1 5~07 2 An embodiment of the inventlon is explained on the basis of schematic drawings~ as follows:
Fig.1 Exploded view of the individual parts of a radiator mountlng in accordance with the invention, Fig~2 Vertical s~ction II-II in Fig.1, Fig.3 Two half-side sections in h~rizontal planes III-III
in Fig.2, Fig.4 Plan view of installed radiator mounting and Fig.5 Vertical section V-V in Fig~4.
The separately ~hown component~ in Fig.1 make up a radiator mounting 10 which, as shown in Fig.4, is for ~ixing between - two tubes 12 of a tubular radiator or likewise between two fi~s of not illustrated finned radiators of various sizes.
One component of the radiator mountlng 10 is a~plate 14, which i~ the illustrated example is a bent-to-shape ~heet m~tal ...-pressing.~*aturing a central hole 16. The central hole 16 is of circular shape with an overlapping square. Parallel to the horizontal edges of the square there is one crimp 18 acro3s the sheet metal above the hole 16 and one below it. At the e~ds oY
the crimps 18, the plate 14 has supporting surfaces 20 for the radiator tubes 12~ Just beyond the supporting sur~ace~ 20 on the outside, the plate 14 is stepped and a second pair of supporting surfaces 22 is formed ~or small radiator fins.

The radiator mo~ntlng 10 also has a clamping piece 26, which in ~he illustrated example ls basically a prls~-~haped piece o~ 5heet ~e~l With two slde m~mber~ 28 o~ rou~hly U~shaped 3Q cros~ ~ec~io~ eaoh ha~in~ a web ~0 and tWo le~ 32. The outside .
oI the web 30 o~ each side member 28 ~or~s a supporting surface 34 whi~h ha~ groove~ acros~ it and con~iti~u~es a :Erame Ior a central portion ~6 drawrl lnwards with an M-,shaped cro~s section.

3S The tWQ 5i~e member~ 28 are manu~actured as a single piece 1 15~07 _ 4 _ ~ oined by a bridge 40. As ~hown in Fig.1, the contour of the brldge 40 matches the ce~tral hole 16 in the plate 14 in ~uch a manner tha-t the bridge 40 can be pushed through the hole 169 as shown in Fig.4. The bridge 40 also features a central hole 42.

As shown in Figs 2 and 4~ a screw 44 wi th a conical head 46 at its end remote from the bridge 40 passes between the drawn-inwards, M-shaped cross-section central portions 36 o~
~o the side members 28. A keeper 48 ls inslsrted bshind the bridge 40, after it has been pushed through the central hole 16, in the space between the bridge 40 and the plate ~4, the r~ctangular shape o~ said keeper 48 in the illustra-ted example being such that the bridge 40 can be braced by the keeper 48 against the plate 14, i.e., is retained from being drawn back through the central hole 16. The keeper 48 has a hole 50, which is a threaded hole in the illustrated example. The screw 44 is screwed through this hole 50, passing beyond it through the hole 42 in the bridge 40, the latt~r hole being a through hole i~ the illustrated example.

A variant of what is shown can have hole 50 as a through hole and hole 42 as a threaded hole.
~,, Screw 44, which has a slot 52 in its head 46 and at :Lts other end for a screwdriver, passes through a spreader 60, which ~e~tures a through hole 62 for this purpose~ A~ show~ in Figs 1, 4 and 5~ the spreader 60 ha~ a wedge shaped cro~s ~ectlo~ and t~pers i~ the sam~ direc~ion as -the head 46 of ~he screw 44, namely tewards ~h~ pla~a 14, so that it c~n be drawn in between the ~ide members 8 whsn the ~crew 44 is -tighte~ed~ The through hcle 6~ in -the ~preader 60 ha~ a conlcal enlargement 6~ m~tching the head 46 of the ~crew 44 at its end remote from the pla-te 14.
~he spreader 60 al~o has a lon~itudiTlal slot 66 in lt~ cen-tral plane between the two side members 28 at the end awa~ from the plate 14.

115~;~7~' As shown in Fig.3, the side members 28 are ~nltially parallel.
However, when the screw 44 is tightenedD its head 46 draw~
the spreader 60 in between the side members 28, causing the latter to spread, as shown ln Fig.4. Owing to the resistance offered by the side members to the spreader 60 7 the screw 44 shifts within the spreader 60 when the former is further tight-enedJ so that the latter spreads in turn as the head 46 o~ the screw 44 penetrates further into it and the spreader 60 penetrates further between the drawn-inwards central portions ~6 of the side members 28. In this way, the side members 28 are forced part~cularly effectively apart and their supporting surfaces 34 are pressed firmly up against the tubes 12 of the radiator. The reaction forces thereby set up cause the supporting surfaces 22 of the plate 14 to be pressad against the tubes 12.
The firm connection created in this manner betwee~ the radiator mounting 10 and the radiator makes it possible to support the radiator by means of two or more radiator mountings 10 spaced suitably apart on a corresponding number of wall plugs 54, as shown in Fig.4. For this purpose 9 the wall plugs 54 can have a head 56 with a~ annular groove which engages with a flange 58 of the plate 14.
