Abstract

A rest support for irradiation units, primarily so-called solaria, intended for a person preferably lying on one's back, comprising a pane (3) or the like, which at least to its greater part is transparent and intended to be transilluminated from below by at least one radiation source (4), and on which said person is intended to rest. The rest support is especially characterized in that said pane (3) comprises two longitudinal edge portions (5) of preferably plane cross-section, one portion on each longitudinal side, which portions are intended to be substantially horizontal and to serve as support for said person's arms, and a portion (6) of substantially V-shaped cross-section, which is formed by two portions (8) slightly inclined downwards from the respective edge portion (5) to the longitudinal central line (7) of the pane (3), which portions are intended to serve as support for said person's head, back etc., and that in connection to said central line (7) a longitudinal depression (9) is located, which is intended for said person's spine column.

Description

Rest support for irradiation Units

This invention relates to a rest support for irradiatien units, primarily so-called solaria, intended for a pers¬ on preferably lying on one's back, comprising a transpar- ent pane or the like, which is intended to be transillum- inated from below by at least one radiation source, and on which said person is intended to rest.

Known rest supports c «omprising a plane horizontal pane have considerable disadvantages. A person lying on one's back on a known support and holding the arms slightly outward from the body, for example, lies relatively un¬ comfortable, and at the same time the chest and the sides of the arms are subjected to relatively little radiation.

The present invention relates to a rest support, which is designed ergonomically, extremely comfortable and formed for optimum irradiation under in other respects definite conditions.

The present invention, thus, relates to a rest support for irradiation units, primarily so-called solaria, intended for a person preferably lying on one's back, and comprising a pane or the like, which at least to its greatest part is transparent and intended to be transilluminated from below by at least one radiation source, and on which pane said person is intended to rest.

The invention is especially characterized in that said pane comprises two longitudinal edge portions of pref¬ erably plane cross-section, one portion on each longit¬ udinal side, which portions are intended to be subst- antially horizontal and to serve as support for the arms of said person, and a portion of substantially V-shaped cross-section, which is formed by two portions slightly inclined from the respective edge portion to the long- itudinal central, line_c_f the pane, which portions are intended to serve as support for the head, back etc. of said person, and that in connection to said central line a longitudinal depression is located, which is intended for said person's spine column.

The invention is described in the following with ref¬ erence to an embodiment thereof and to the accompany¬ ing drawing, in which Fig. 1 is a. vertical transverse section through a very schematically shown first embod- iment of a rest support according to the invention,

Fig. 2 is a perspective view of a pane at a rest support according to Fig. 1, ^'Fig. 3 shows the pane substant¬ ially according to Fig. 2, seen toward an end surface, and Fig. is a vertical transverse section through a very schematically shown second embodiment of a rest support according to the invention.

In Fig. 1 the rumeral 1 designates a person lying on one's back, for which person the rest support 2 accord¬ ing to the invention is intended. The numeral 3 design- ates a transparent pane or the like, which is intended to be transilluminated from below by at least one, but preferably a plurality of radiation sources 4, and on which the person 1 is intended to rest.

The said pane 3 comprises two longitudinal edge porti- ons 5 of preferably plane cross-section, one portion on each longitudinal side, which portions are intended to be substantially horizontal and to serve as support for the arms of said person 1, and a portion 6 of substantially V-shaped cross-section, which is formed by means of two portions 8 slightly inclined downwards from the respective edge portion 5 to the longitudinal central line- 7 of the pane 3 and intended to serve as support for said persαnέ*. head, back etc., as shown in Fig. 1. The numeral 9 designates a longitudinal depression in connection to said central line 7, which depression is intended for said person's 1 spine column.

According to preferred embodiments, the pane 3 is form- 5 ed in one piece of transparent material, for example plexiglass, as shown in Figs. 2 and 3*>

According to preferred embodiments, radiation sources are provided in the form of longitudinal tubes 4, Figs. . 1 and 4, which are located in connection to the lower

¹⁰ surface 3' of the pane 3, and the majority, preferably all, of the tubes 4,4', which join said edge portions 5 at least at the transition from the edge portion 5 to

^• the V-shaped portion 6, are located at a higher level than preferably all remaining tubes 4,4". At the e bod-

15 i ent according to Fig. 4, thus, all tubes 4' arranged under the portions 5 are located at a common level, which is higher than the common level, at which the tubes 4" arranged under the V-shaped portion β are located.

20 At the embodiments shown in Figs. 1-3 of the pane 3, the pane terminates at the outer edge 10 of each edge portion 5 with a downward bent longitudinal flange 11 or the like, which overlaps portions 12 comprised in the support and carrying the pane 3, as shown schemat-

25 ically in Fig. 1. The cleaning of the pane and support is hereby facilitated.

The mode of operation of the arrangement according to the invention substantially should have beσome apparent from the aforesaid. The horizontal edge portions 5

"\ 30 provide the person 1 with a support for holding the arms comfortably in the way desired even during long periods, at the same time as the person does not_. have to rest on the spine column, and a.o. due to the high location of the radiation sources 4' at the edge portions 5 opt- imum utilization of the radiation sources for irradi¬ ation is achieved. This applies, of course, especially to the side portions of the body and arms.

As should have become apparent from above, essential advantages compared with prior art are brought about by the invention with very simple means.

The invention has been described above with reference to embodiments. More embodiments, of course, and minor alterations can be imagined without thereby abandoning the invention idea. Certain deviations, for example, from the location of the radiation sources as suggested above can be made. It also is possible to imagine deviations from the stated cross-sectional shape of the pane 3 where it is not entirely necessary, such as at the intended foot end of the rest support.

According to a preferred embodiment, the rest support is designed substantially according to the Swedish patent (patent application i /&9..-/ ) where means 13 are provided for directly and/or indirectly determining the operation temperature of at least one radiation source 4, and means (not shown) for comparing values thus scanned, constituting actual values, with a predetermined nominal value or nominal value interval and adjusting the capacity of at least existing fans 14 for cooling the radiation sources of the rest support and said pane 3 by forced air cooling, so that a pre¬ determined relation between actual value and nominal value or nominal value interval is obtained.

It is, of course, possible to imagine embodiments where certain or all radiation sources are of a kind different of the longitudinal tubes shown here.

At the embodiment of panes 3 shown in the Figures, the depression 9 does not extend all the way out to the respective end surface of the pane. Embodiments, how- ever, can be imagined where the depression extends from one end surface to the other.

The invention, thus, must not be regarded restricted to the embodiments set forth above, but can be varied 5 ithin the scope of the attached claims.
