Abstract

A tent of the type in which the sides slope unbrokenly from the ridgepole too the ground, and whereof the ends have the form of an A without the crossbar, is modified to counter the effects of wind, or wind and rain, on the side walls thereof when pitched by mounting on the ridgepole (10) centrally of its length a support (16) of wishbone shape which is disposed symmetricaily about that plane which contains the ridgepole axis and is normal to the ground when the tent is pitched and whereof the limbs (20, 21) bear on the inner surfaces of the side walls of the tent, or of the side of the outer skin when the tent is double-skinned, and confer on the side walls of the tent or of the outer skin an outwards curvature most pronounced centrally of the side walls and shallowing in each direction towards the respective end of the tent. When the tent is double-skinned, i.e. has a fly-sheet, the limbs (20, 21) of the wishbone-shaped support (10) exert resilient pressure on the sides of the fly-sheet, and connectors fitted to the outer surfaces of the side walls of the inner skin are hooked on to the lower ends of the limbs (20, 21).

Description

SPECIFICATION Improvements in or relating to ridge tents This invention relates to ridge tents ofthetype in which the sides slope unbrokenly from the ridgepole to the ground, the ends, usually closed by flaps, having the form of an Awithoutthe crossbar, for which reason this type of ridge tent is also known as an Atent. A ridge tent ofthe type stated may be fitted with a fly-sheet which is a piece of canvas pitched outside and over the ridge ofthetent as extra protection from the sun, rain, etc.

In windy conditions, a side wall of a pitched ridge tent of the type stated may be blown inwardly and present to the wind a concavity which catches the wind and may result in the tent being blown down if the wind is of sufficient stength. If tent is fitted with a fly-sheet, the latter may be blown inwards into contact with the inner tent and cause leakage in windy and wet conditions.

With a view to countering the effects of wind, or of wind and rain, a guy has been fitted to each side wall of the tent substantially midway of both the width and slope of the side wall and secured at ground level by a tent-peg, the guy being then at an angle of 30 or thereabouts to the gound. As a consequence, the slope of the side wall where the guy is secured thereto is of similar character to a dog-leg which gradual increase of the dog-leg included angle in each direction towards the ends ofthe tent.

Disadvantages of such sidewall guys are that extra pegging points have to be found therefor, considerable strain is exerted on the side walls ofthe tent where the guys are attached thereto and the tent fabric may be torn, and the guys present a hazard to movement of people outside the tent, one certain result of anyone trip ping over a guy being, of course, momentary aggravation of the aforementioned strain exerted on the respective side wall.

The object of the present invention is to provide an alternative to the guys, which fulfils the function ofthe guys without being subject to the disadvantages of the latter.

In accordance with the present invention, the ridge-pole of a pitched ridge tent ofthe type stated carries centrally of its length a support of wish bone shape disposed symmetrically aboutthe vertical plane containing the axis of the ridgepole and conferring on the tent side walls orfly-sheet an outwards curvature most pronounced centrally of the side walls and shallowing in each direction towards the respective end ofthetent.

Also in accordance with the invention, a ridge tent of the type stated is modified to counterthe effects of wind, orwind and rain, on the side wallsthereofwhen pitched by mounting on the ridgepole centrally of its length a support ofwishbone shape disposed symmetrically about that plane which contains the ridgepole axis and is normal to the ground when the tent is pitched.

An embodiment ofthe invention will now be described, by way of example, with reference to the accompanying diagrammatic drawings, in which: Fig. 1 illustrates the inwards curvature of a side wall of a ridge tent ofthe type stated as a result of wind blowing towards that side wall; Fig. 2 is a transverse sectional view of a ridge tent of the type stated with guys attached to the side wall thereof; Fig. 3 is a transverse sectional view of a ridge tent of the type stated in accordance with the present invention; Fig. 4 is a perspective view illustrating on a larger scale the support ofwishbone shape ofthetent of Fig.

3;and Fig. 5 is a view similarto Fig. 3 but illustrating a double-skinned ridge tent of the type stated, i.e. one fitted with a fly-sheet.

Referringfirstlyto Fig. 1 the ridgetentofthetype stated includes a ridgepole 10 and side walls 11 and 12. Atent-peg is denoted 13 and the sidewall 11 is curved inwardly as a result of wind blowing in the direction of the arrow A.

In Fig. 2 a guy 14 is fitted to each ofthe side walls 11 and 12 of the tent substantially midway both ofthe width and slope ofthe respective side wall, each guy 14 subtending an included angle of about30 when secured to the ground by a tent-peg 15.

In Fig. 3, the ridgepole 10 carries centrally of its length a support 16 of wish bone shape disposed symmetrically aboutthe vertical plane containing the axis ofthe ridge pole 10. The support 16 confers on each ofthe side walls 11 and 12 ofthe tent an outwards curvature most pronounced centrally of the side walls and shallowing in each direction towards the respective end ofthetent.

The support 16 is illustrated in more detail in Fig. 4. It comprises a central yoke 17 whereofthe arched cavity is spanned by a plate 18 having a hole 19 therethrough midway of its width. The yoke 17 and plate 18 with the hole 19 may be a plastics moulding. Two resilient legs or rods 20 and 21 extend from the yoke 17, one from each ofthe end faces of the yoke, and continue the camber of the limbs of the yoke.

The yoke 17 has an opening centrally of its length through which the ridgepole 10 and the yoke is made fast with the ridgepole midway along the length of the latter. When the tent is pitched, the legs or rods 20 and 21 exert resilient pressure from within on the side walls 11 and 12 and prevent blowing inwards ofthe sidewalls in windy conditions.

In Figs. 5,the legs or rods 20 and 21 are between the two skins ofthe tent and exert resilient pressure on the sides 22 and 23 ofthe fly-sheet. Connectors 24 and 25 are fitted to the outer surfaces ofthe side walls 11 and 22 and are hooked on the lower ends ofthe legs or rods 20 and 21. These connectors 24 and 25 both maintain a set spacing between the two skins and pull the walls 11 and 12 ofthe inner skin outwardly, thus increasing the space inside the tent. The hole 19 in the plate 18 ofthe support 16 can be used to help in the suspension of the inner skin.

In a modification patches incorporating sleeves for reception ofthe lower ends ofthe legs or rods 20 and 21 are fitted in the appropriate positions on the inner sufaces ofthe side walls 11 and 12 of a single-skinned tent, or ofthe sides 22 and 23 of a double-skinned tent.

The patches prevent rubbing ofthe legs or rods 20 and 21 on the respective walls. Anchor points may be attached to the outer surfaces of the walls 11 and 12, or 22 and 23, directly opposite the patches. In the event of winds of excessive strength, storm guys could be attached to these anchor points.
