In Figures 1 to 3, there is shown in 1 a vertical amount of a towel radiator, of the type comprising a number of bars horizontally heated, for example of oblong section as shown in 2 in Figures 1 and 2.

The amount 1 is for example a tubular extruded aluminum profile to two longitudinal compartments, namely a first compartment 3 in communication with each heating bar 2 by an orifice 4. The heating bars 2 is provided for example by a heat transfer fluid generated by an appropriate device, in the known manner, circulating in the leads 3 and in the bars 2.

The heating of the bars 2 can also be provided by cables or heating cords arranged in the bars and in one or the other uprights 1, or radiating films arranged inside bars against the front inner wall of the latter.

The second compartment 5 is connected to an air generation system hot or cold drying (not shown).

For example hot air is sent into compartment 5 at a end from a turbine drawing ambient air, heated by a electrical resistance.

On the outer side of the upright 1, opposite compartment 5, is conformed along the entire length of the amount a slide defined by two wings in return 6 constituting two guide grooves of a slide 7 on which is fixed at one end of a drying tubular bar 8, of section oblong (Figure 1) and provided with 9 air outlet orifices directed downwards.

The slider 7 has a general shape of rectangular platinum with a peripheral flanged edge 7a extended on the lateral flanks by a return outside 10 cooperating with the grooves of the wings of the slideway 6.

The end of the towel bar 8 passes through the platen of the slide 7 by an oblong orifice and opens into the compartment 5 of the amount 1 by a slot 11 formed in the outer face of the profile and running over the entire height of said amount.

Between the slider 7, the slider 6 and the amount 1 is arranged a sealing device constituted by an annular seal 12 of elastomer 12 rectangular shape (Figure 1). The seal 12 is arranged under the plate of the slider 7 and bordered laterally by the peripheral fallen edge 7a and by two upper and lower side walls 7b and 7c (FIG. 3) of the slider 7.

The interior of compartment 5 is lined with a flexible waterproof sheath 13 elastomer, open facing the slot 11 through the intermediaries two edges facing and overlapping each said sheath, respectively 13a and 13b.

These two edges 13a, 13b deviate locally under the pressure of the end 8a of the bar 8 which protrudes into the compartment 5.

As can be seen in Figures 2 and 3, the seal 12 has a reduced section flattened in its part (Figure 2) interposed between the tube 8 and the flanks 7a, 7b, 7c of the slider 7, while it has a section circular section (FIG. 3) in its part interposed between the tube 8, the slider 7 and the edges 13a, 13b overlapping the sheath 13 on either side of the tube 8. This is done around the opening made locally by the end 8a of the drying bar by spreading the edges 13a, 13b, a seal practically avoiding air, necessarily overpressure inside the sheath 13, does not escape outside at the junction between slider 7 and slide 6. Outside the area where the slide 7, the slot 11 of the amount is closed by the mutual recovery two edges 13a, 13b pressed against each other by the internal pressure of the air.

The slider 7 is extended in the lower part by a plate 11 carrying a knurled knob 15 screwed into the plate and provided at the end of its threaded rod of a clamping shoe 16 cooperating with the bottom of the slide formed by the external face of the profile-upright 1.

The button 15 serves essentially to block the slide 7 at the location desired along the amount 1.

The drying bar 8 is fixed at one end only to a 7 single running slide along one of the amounts of the towel rail, the other end of the bar being free and closed, be attached to both ends, in the same way, on the two identical the device.

The bar 8 is easily movable by hand by sliding the slides 7 in their slide. As the slider 7 moves, the end 8a of the bar moves the air passage opening between the upright 1 and the bar 8, the facing lips formed by the edges 13a, 13b of the split sheath 13 closing themselves by overlap on either side of said end 8a.

All bars 8 are in communication with the interior of amounts 1, but can alternatively, especially in the case where the bars 8 have a circular section, provide them with shutter valves if you do not want to not that this or that drying bar is in use.

It should be noted that the extruded profiles constituting the amounts 1 define a slide 6 open at both ends, thus allowing the setting up or removing drying bars 8, at will.

In order to allow insertion or extraction of bars 8, the said ends of the uprights are provided with movable or removable means ensuring both the necessary sealing and the passage of the sliders 7.

Figures 2 and 3 are diagrammatically arrows the circulation of the drying air, hot or cold, inside the upright 1 and the bar 8.

Figures 5 to 7 illustrate an alternative embodiment of the slide applied to a profile-amount of the same type as that of Figures 1 to 3.

According to this variant, the means (15, 16) for locking in position 7 'slide, also identical to those of Figure 3, are arranged laterally at the height of the towel bar 8 ', here constituted by a circular section tube, which bar thus masks the control knob 15.

The plate of the slider 7 'has a different shape for this purpose, wider and lower, and occupies virtually the entire width of the profile 1. The wings 6 defining the guide grooves of the slide 7 'are located to the right of the edges of the profile, the button 15 moving next to the first compartment 3 internal to the amount.

The penetration of the end 8'a of the tube 8 'into the slider 7' then in the second compartment 5 of the amount 1 is done in the same way, in view of the two overlapping lips (13a, 13b) of the internal split sheath 13.

The annular seal 12 'has a circular section constant and a suitable shape (Figure 4) to the section of the tube 8 'and covering the entire area where there is an opening between the edges 13a, 13b due at the presence of the tube 8 '.

Figures 7 and 8 illustrate another variant in which the flank external of the profile-upright 1 'is provided with place in place of orifices 17 closed permanently by internal valves 18 with elastic return by springs 19, arranged in the second compartment 5 of the amount.

The slider 7 "is a simple plate with side edges slide in grooves formed by wings 6 identical to those of the figure 5.

Laterally, at the height of the connection of the circular section tube 8 'to the plate of the slider 7 "and facing the compartment 3 is arranged a blocking means of the latter consisting of a button 15 and a pad 16, similar to those of Figures 3 and 5.

Next to the compartment 5, the plate of the slider 7 "is connected at the end of the tube 8 'which is thus likely to be just opposite of an orifice 17 as illustrated in FIG.

In this position, the valve 18 facing the tube 8 'is brought into opening position by the action of a control button 20, screwed on the slider plate 7 ", under the tube 8 ', and whose threaded rod spreads the valve 15 from its seat (Figure 8).

It should be noted that the button 20 allows at will to put into operation or not the drying bar 8 'and therefore to select on the radiator the one or more bars that we want to use.

Arrows in Figures 7 and 8 indicate the air circulation of drying, the compartment 5 of the amount 1 to the tube 8 '.

In general, slides, slides and uprights tubular conveying the drying air can be made from different way especially depending on the configuration of the device Towel.

This can indeed include a housing in which is arranged a heating system, in particular by radiation, and on any of the flanks, or both are reported tubular uprights air distributors drying machines equipped with slides and slide bars according to the present invention.

The blocking means in position of the sliders can be constituted by other means, for example a quarter-turn cam, mounted on the slide and cooperating with a portion of the slide.

The invention applies to devices towel rail towel bars of any morphology, square, rectangular, round, oblong, pyramidal, etc.

Moreover, the slides extend over all or part of the height of the heater and consist of profiles or plates of pre-formed metal that can be attached to the frame or housing of apparatus by any means, mechanical, chemical, adhesive, etc ... appropriate.
