Tourist tents
The most widespread kind of marching equipment is the tent. She should have the minimal dimensions, mass and cost, easily to be established(installed), provide comfortable conditions, to be idle time in manufacturing.To destination them section into types: hunting, marching, family and for a camping.
The tent of the first type 1-2 persons is calculated by capacity for short-term hikes. She is small in the sizes, has the minimal mass (counting upon one person) and provides reliable protection against a rain. The hiking tent is intended for the sports travel which are passing(are taking place), as a rule, in enough complex(difficult) conditions. She should protect reliably from a rain, a wind, a cold, easily to be established(installed) in complex(difficult) meteorological conditions, to provide good enough conditions of dwelling in a long hike, to have the minimal dimensions and mass.
The family tent is calculated on free enough housing 2-4 person, has additional elements in the designs doing(making) it(her) with more comfortable: a luggage carrier, L-shaped racks, etc. Tourists use this tent in simple hikes; thus some weight gain of equipment does not play an essential role.
The tent for a camping the most convenient, comfortable, but has a complex(difficult) design, the greater(big) mass, is difficult in the equipment(installation). It(her) apply in the motorized kinds of tourism, at carrying out of meetings and competitions.
The design of tent and materials applied to its(her) manufacturing substantially depend on a season (years(summer) and winter) and district of travel (a wood zone, open-spaces, steppe, tundra and mountain district). For a wood zone any tents approach(suit). For travel on steppe and tundra it is expedient to choose tents which can resist to strong winds, protect from the sun and a cold. In this case the sizes of tents are not limited.
Fig. 1. The scheme(plan) of prismatic tents: and - odnoskatnyh; - dvuhskatnyh type "small house"
Demands to tents for mountain travel are most complex(difficult) and inconsistent. They should protect reliably from a rain and snows at impossibility to provide the good extension(spreading device) (the slope, a rough platform), to resist strong winds, to protect from cold, to be established(installed) in complex(difficult) meteorological conditions, to provide an opportunity of cooking in inclement weather, not leaving from tent.
Many qualities of tents: the windproof, the specific charge of a material, convenience of the equipment(installation) depend on their form: prismatic, pyramidal, hemispherical, cylindrical. In tab. 1 the basic characteristics of tents of the various form are resulted(brought). Prismatic odnoskatnye tents are simple and convenient in raskroe, are easily stretched(easily dragged out) between trees, but not so well resist to winds, therefore more approach(suit) for hikes on forest land (fig. 1,).
Prismatic dvuhskatnye tents - "Pamirka", "poludatka", "Moskvichka" have simple and rational open, good obitaemost, are simple enough in the equipment(installation) and are universal in application (fig. 1,).
Pyramidal, and especially cylindrical and hemispherical tents possess a good windproof, are simple in the equipment(installation), therefore find application on polar expeditions(dispatches) where these qualities are very important. However tourists apply their century hikes seldom. It speaks that such tents for mass tourism do not produce(make), and open them it is combined(complex;difficult).
From this group it is expedient to apply to base camps and winter complex(difficult) travel tent chetyrehskatnye (fig. 2), and also various modifications trehskatnyh tents (ðèñ.3).
Tent tents possess good obitaemostju, for their equipment(installation) only one rack is required, as a rule. However in connection with small height of an input(entrance) in them it is difficult to provide good ventilation in a hot season. An essential disadvantage is also that the awning for these tents is combined(complex;difficult) enough in manufacturing: it(him) sew under the form of tent. And the last - the rack which establish(install) in the center, considerably worsens obitaemost camp dwelling.
