a ~ 7 Curtain rail and method of it~ manufacture.

he lnvention relates to a curtnin ri~11 con~istir.g o~ a proile provided wlth a sllt for allowing pa~sage eO
,~ curtaln hanglng device~, and next to ~aid s~t a space f~r receiving slldlng or rolling parts of the curtaln hanginq devicen.

Such curtain rai1s are known in many embodimont~.

The 6hapq o~ the profile i9 dependent on the curtain lo hanging devices u~ed. Snid devloes may bc prov~dcd with ~:
rollinq part6 ln thG ~hape of running wheels, often -~ :~
referred to as runners, or with 61iding devices, often made of synthetic material.

15 Further~ore, there are curta~n hanging d~vice~ that are to ::
be inserted at the end ~lde of the rail, in no way being allowed passaqe through the alit, and c~lrtain hangins device~ that can be inserted through the sllt. Of the .~ - :
latter kind there exist two main variant~, i.e. those that . -:
are reoillent whon pa~ed throug~ the ~lit, and the e~bodi~ont which prov.;des that thc curtAin hanging devicee can be lnserted into the elit in one position only and, a~tcr havlny been turned, ucually at a right angle, obtain the operatlng positIon whicn preYentc pa~sage throuqh the '-~
sllt.

lt is not unu~u~l that at the part which extrudeY the sli.t, ourtain hanging device~ are fitted with a restraining or ~toyplng part that prevents the hanginq device fro~
enterlng the 61it too deeply, as a result of which it n~ay take an uncontrolled position, which m~y lead to lrrequ1aritie~
Tho way a curtain iFi drawn alon~ a curta1n rall often conei~t~ o~ grabhin~ the cu~taln lt~el~ or else t~e curtal.n cord. In that ca~e the force exerted on the curtain i~
often not parallel to the curtain ~uIface, tran~ver~e :. '~ ..".,' : ' ' . ' ` '.

forces belng exerted instead.

8~metlmel- n oure:aln hanglng d~vlc~ b~comQs out of allgnment, as a result of which it gets more or le9~ stuck.
~he aforementioned efrects nay give cause rOr ~riction when the various types of curtain h~nging devicee are u~ed. ~nce frictlon ha~ occurred, it ~ay lead to the first hanglng device taklng a wrong positlon, re~ulting ln an increa6e of 10 the resistlng force already experienced. Due to the ;~
re6i~ting force and the norm~l reactlon thereto, belng tugging, not only the curtain oan be damaged, like a hanging devlce tecomlng dl6engaged, but abra6ion of the rail may also occur, ln particular abra~lon of a possible coat of varnish. In ~ractlce thls ~hortens the life of the rail, because r-palntinq with ~ mechanlcally ~uf~iclently ~trong paint i~ very dirflcult, in whiCh case it should be ~ept in mlnd that the original coat of varnish often is obtsined by applylng powdor, for lnstance by mean~ of ~:;
electrostatlc spraying, followed by heating the rail carrying the coat of powdor untll the latter i~ burned in, areatlng a tightly ~ealed layer.

The lnventlon alms at elloinating the aforementioned disadvantage~ Or friction, lncluding the abra~ton mentioned above, or at any rate at reduclng them.

duty' cases, such as a hea~y curtain th~ f4r7quently has to .~
~ be drawn. 210~

The invention i~ particularly of use when, in a way known per se, the profile wall ad~acent to t~e slit has been rounded off and has been slightly bent inward. In that case the weight of the curtain will be entirely on the rounded edges adjacent to the sl.it, thus on a small surface.
It has been ob6erved that also in that case a polyvinyl layer ~s highly abrasion-resl~tant and friction reducing.

.
A curtain rail is preferably provided with reinforcing - ~.
ribs. When, however, 9uch ribs come into contact with the : curtain hanging device~, this may easily lead to abrasion . 15 and thereafter to increas~ng friction. In applying the invention this disadvantage is reduced to a high degree.
further embodiment of the invention accordingly provides that the profile has inward stick~ng ribs acro~s the slit that are positioned in the wldth direction beside the slit.
An effective method of ~an~ufacturing a curtain rail in accordance with the invention i9 con~tituted in that the :~ .
r~il i8 vertically immorsed into thin liquid thermoplastic .
synthetic material, li~te~ out of the liquid, made to drlp dry at or approximately at the temperature of the liguid and ie cooled down aft-rward~. :
.
In practice this can be effected by hanging the rail lengthwise in a deep container fllled with liquid thermoplastic 6ynth~tic materIal and 6ub~equently by withdrawing it relatively 510wly. The part that has ~ust left the liquid is sti.ll warm and is therefore capable of ~ :
dripping dry ~atlsfActorily. When the entire rail has been Ilifted out of the liquid, only the bottom part is left to 35 drip dry, wherea~ the upper part has already cooled down. m- -~...
A rail thus coated wit~ polyvlnyl chloride has a layer of ~aid synthetic material that ls 80 thin (in quantities of .:~
tenths of millimetres) that little material i5 used, which ':

r~- ~ 2 ~ 1~ 2 1 ~ 7 limlts the cost aB well. These cost are certainly low compared to the cost of the finishlng procesB ~ which i~
us~ally carried out prlor to Applying the ~o~ ln accordance with the invention. For a rail made of alu~inum -the finishing consi6ts of hardening the str~ngpressed rail, degreasing it, chromatizing it ~s a protection again6t oxidation and to prevent depo61t in moist surroundings, applying a powder coating at the inside and outside of the rail by ~eans of electroetatic spraying and muffling it.
Such a ~uffled layer may be smooth, but considerably less 80 than, for instance, a layer of~polyvinyl chloride. -~

The invention will hereinafter be further explained, -reference being ~ade tot t~e drawing where: -fig. 1 shows a cross section of a curtain rail according to the invention; and fig. 2 schematically showc the layering structure thereof.

In fig. 1 a cross section of a curtain r~il is shown with a body 1 and upright legs 2. The legs are bent inward at their ends and thus form f langes 3 which have a bending and thlckening 4 at their endc ad~acent to the sl$t 8, which form supporting ridges 5 at the inside of the profile.
Reinforcing ribs 6 reinforce the body 1, in which case it 25 is irrelevant whether they come lnto contact with runners ~ ~
or ~liding devices that are not drawn, because said ribs ~ -are coated with a protecting, friction reducing ~ayer. The thlckenings 7 between the body 1 and the legs 2 likewise serve a~ r~inforce~ent.

In fig. 2 the aluminum of the rail is lndicated by 9, the chromatized ~ilm by 10, the muffled layer by 11 and the layer according to the invention by 12. For the sake of clarity lo and 12 are proportionally drawn too wide.
