(54) Title: A LATRINE DEVICE FOR FIELD USE
(57) Abstract: A latrine device for field use comprising a plate (I) with a drainage hole (7) which is placed over a latrine hole (2) or trench dug in the ground. The plate has foot supporting areas (30) on each side of the drainage hole.
A LATRINE DEVICE FOR FIELD USE
The present invention relates to a latrine device for field use, in particular for temporary aid purposes.
In connection with the accommodation of victims of catastrophes of nature and war acts in camps, which often hold a very big number of people and which may be very primitively established in respect of sanitary conditions, bad sanitary conditions without access to water constitute a considerable health risk and often entail epidemics also on account of bad nutrition and inadequate access to medicine and medical attention.
Particularly such bad sanitary conditions present 15 especially in case of bigger reception camps the risk of a considerable number of victims.
Various embodiments of latrines are known from US Patents Nos. 1,575,131, 1,574,339, 3,410,092, and 3,203,007, which describe primitive portable latrines in connection with foldable tents suited for camping, military exercises and the like. These latrines are, however, space demanding even when stowed and are, therefore, less suited for use in connection with war acts, catastrophes of nature, etc., where a big number in a relatively short time is to be transported to often remote places. Due to the often impassable country this transport is normally carried out by air plane, and low weight in combination with good stack ability is in this connection an important property, which distinguishes the latrine device according to the invention from the prior art.
The object of the present invention is to present a solution which under the circumstances constitutes an improvement for use in places, where it is not possible to establish water flushing toilets or to deliver and erect more effective chemical closets.
The latrine device according to the invention is with a view to this characteristic in comprising, for use as lower horizontal fastening tubes for the shielding enclosure, said vertical and horizontal tubes being mutually connected by means of splicing sleeves. Such tubes may be made from plastics and with standard dimensions, which makes them both cheap in manufacture and low in weight. Additionally, the detachable supporting frame for the shielding enclosure makes it possible to transport the second embodiment of the invention comparatively easy in considerable numbers even to places, which can only be reached by air plane.
The shielding enclosure may according to the invention advantageously be made from reinforced plastic foil with embedded eyelets for connection with fastening members for fastening the enclosure to the supporting frame.
Apart from functioning as a visual shielding from other persons, such tarpaulins, which are a relatively cheap standard article, used i.e. to a great extent for the covering of scaffolds, give a fair protection against the weather.
The invention will be described in detail in the following with reference to the drawing, in which
Fig. 1 is a plane view of a simple embodiment of the invention,
Fig. 2 is a sectional view along the line of Fig. 1,
Fig. 3 is a plane view of a lid for the covering of a drainage hole in the embodiment shown in Fig. 1,
Fig. 4 is a sectional view along the line in Fig. 3,
Fig. 5 is a perspective view of a second embodiment of a latrine device according to the invention,
Fig. 6 is a vertical sectional view of the second embodiment,
Figs. 7 and 8 are examples of fastening members for connection of a shielding enclosure with the supporting frame for the latrine device according to the second embodiment of the invention shown in Figs. 5 and 6 in consideration of the user be provided with a rib contouring 5 with a treading or foot plate 6 placed around said drainage hole 7.
A further supporting of the plate 2 according to the second embodiment can be attained by means of separate crossbeams 8, for instance of wood, which in connection with the erection is placed under the plate 1 between opposite walls of the pendent skirt 3.
According to the second embodiment of the invention shown in Figs. 5 and 6 the plate 1 is connected with a supporting frame for a shielding enclosure for the formation of a latrine cabin, and the plate 1 is in this second embodiment provided with flanged sockets 9 extending from the four corners of the generally rectangular plate 1. For the above-mentioned stacking reasons it is preferable that the diameter of the flanged sockets 9 is tapering, i.e. the end part having smaller diameter than the part integral with the plate 1, whereby the flanged sockets on stacked plates may come to rest in each other. With a view to fastening to the ground the plate 1 may in connection with the pendent skirt 3 be provided with a horizontal circumferential edge flange 4.
Moreover, the plate 1 is provided with a passage 24 for a vent tube 25, which from the dugout latrine hole 2 is passed up through the cabin with an outlet opening situated above the upper edge of the shielding enclosure. The vent tube 25 may advantageously be made from heat-absorbing material, for instance black or dark plastic, whereby a chimney effect improving the venting from the latrine hole 2 is attained and consequently a reduction of obnoxious smells in the cabin itself.
The supporting frame may be a tube frame made in a manner known per se from plastic tubes in standard dimensions and comprising vertical corner tubes 10 fitting on the flanged sockets 9 and lower and upper horizontal fastening tubes 11, 12 connected with the vertical corner the eyelets 22 substantially facing each other.
The simple construction of the latrine device according to the preferred embodiment and the complete detachability of the latrine device according to the second embodiment makes it possible to easily transport a considerable number of latrines with or without supporting frame as stacked plates and demounted supporting frames even with a limited transport capacity to remote and isolated areas.
The erection of the latrine may be performed easily and quickly also by unskilled persons, and the latrines may likewise easily be moved, when the capacity of the latrine in question is fully exhausted.
According to requirement a considerable number of cabins 26 may as shown in Fig. 9 be erected side by side and in several rows, for each of which a common latrine trench has been dug.
8. A latrine device according to claim 6, characterized in that the supporting frame is provided with vertical corner tubes for connection with said flanged sockets and upper and lower horizontal
5 fastening tubes for the shielding enclosure, said vertical and horizontal tubes being mutually connected by means of splicing sleeves.
9. A latrine device according to any of the preceding claims, characterized in that the shielding enclosure is made from reinforced plastic foil with embedded eyelets for connection with fastening members for fastening the enclosure to the supporting frame.
10. A latrine device according to claims 8 and 9, characterized in that said fastening members
15 comprise plug-like members mounted in said eyelets and with a head abutting the outer sides of the enclosure and at the inner side a protruding side portion in connection with a resilient loop for surrounding the fastening tubes.
11. A latrine device according to claims 8 and 9, characterized in that the enclosure is passed around the upper fastening tubes and provided with two rows of eyelets, which, when passed around the tubes, are brought into a position substantially opposite one another for mutual connection by means of a connecting member.
12. A latrine device according to claim 10, characterized in that said connecting member is a substantially H-shaped anchor, the transverse leg of which is inclined relative to the legs which at the mounting are brought to abut against one side of each of the eyelet's facing each others.
