Abstract

The hunting sightseeing facility comprises a triangular platform (10) articulated to a frame (20) provided with two ground support points and forming ladder access to the platform. There is a retractable leg (30) and a foldable safety rail (61-63).

Description

['entry of an animal and, opens it, to let out [animal.

  The invention relates to beaten lookouts used.

  for hunting big and medium game.

  The watchtowers of battered wind of small raised buildings from which a hunter poses can shoot the big game with shooting shooting (1 m for the wild boar / roe deer, 1.50 m for the deer). In the compulsory passage points of game, or in the areas it usually frequents, this wind of permanent or semi-permanent constructions, often in wood or tubular, rarely bricked. Elsewhere, we set up temporary watchtowers, which must combine robustness and stability with the possibility of movement. Thus the French request FR-A-2,754,293 describes a movable watchtower for hunting big game, constituted by a rigid metal frame crowned with a platform, on the spacers of the base of which is fixed. a three-point gripping structure to allow it to be lifted and moved by tractor. French request FR-A-2,783,400 discloses a towable traveling watchtower, consisting of a rigid platform frame, provided on one of its faces on the base side, with an axle and two wheels, and on the flat side. forma, of a retractable drawbar, the stability of the device once erected being ensured by stabilization pads. Less bulky wind foldable watchtowers, much lighter structures 2s, but also lacking much stability, which requires to support them to a support found on site, pole or tree. Such is the transportable watchtower intended to be pressed against a substantially cylindrical and vertical support of the European application so EP 1.143. 103, consists of a platform temporarily fixed to the chosen vertical support, a tree for example, and provided with a ladder with telescopic upright which allows access to it. Rigid temporary watchtowers require heavy resources for their movement and their installation; - - folding and therefore transportable watchtowers in a reduced volume known to prior art have the requirement against them

local support.

  The present invention remedies these drawbacks by proposing a totally foldable watchtower, very stable in its configuration of use, which can be carried out without difficulty in a version with variable height, foldable flat in a pattern with very small dimensions, and therefore easily

transportable and storable.

  The folding watchtower of the invention is composed, as shown in FIG. 1, of a triangular platform (10) resting through articulations (51-52), on the one hand on a frame ( 20) provided with at least two support points on the ground and forming a ladder for access to the platform - in the following, we will call this frame-ladder frame - and on the other hand on a retractable foot (30 ), and supplemented in the upper part of a railing (61 to 63) also foldable, ['assembly having various organs intended to subject it, tent in its folded position that

in its working position.

  The platform (10) consists of a triangular frame made, for example in the form of a welded iron frame in L, on which is adapted a floor (not shown) in thin sheet metal, in strong mesh or better in metal deployed, capable of properly supporting the weight of a man. One of its dimensions (11) is reserved for access; the ladder frame (20) is fixed to it. A spacer (14) connecting the side (11) to the top opposite this side, the anointing of the sides (12) and (13), serves both as a stiffener for the platform and as a support for the articulation (52) foot

retractable (30).

  The ladder frame (20) is formed by two hollow lateral uprights (21) connected by bars (22) fulfilling the function of ladder bars. The lower part is a crosspiece (23) which can be directly welded to the base of the uprights (21). We prefer a telescopic mounting: on the crosspiece (23) welded wind, with a spacing equal to that of the uprights (21), sliding bars with gentle friction inside said uprights (21) and positioned by holes - pins. Short feet (24) wind welded at the end

of the crosspiece (23).

  The ladder frame is articulated at the side (11) of the platform by the articulations (51) formed by strong

  hinges or better by a U iron with horizontal axis.

  The retractable foot (30) is a bar, preferably telescopic like the uprights (21). This foot (30) is connected to the tip (12-13) of the platform by means of a fixed part (52) welded on the inside face of the platform, preferably on the spacer (14 ), which separates it from the lower surface of the platform, the connection between this section, con and the base being on a horizontal axis which crosses this part. The piece (52), made for example in a trunk, one of iron in U. is of a length which, at the games necessary for the movements, is equal to the thickness of the ladder frame (20) increased by the thickness of the foot (30). We will understand the function and originality of this device when we describe

  2s further the folding movements of the device.

  The platform is fitted above a railing made up of upright trots; one of them, the upright (61), is erected on its end (1213-14) by means of a joint (54) consisting of a trunk, iron is welded in U at this end and provided with 'a horizontal axis; the other two, the uprights (62), wind articulated each to the two

  other angles by axes (53), and support two bars-

  rails (63) which are articulated on the uprights (62) by i 5 two axes (55) and which come to rest on the upright (61) or

  they are retained by cleats (56).

  Two compasses (41) and (42) connect the spacer (14) respectively to the ladder frame (upper bar (22)) and to the foot (30). In the deployed position, that is to say in watchtower function, the platform is placed on the base constituted by the ladder frame deployed by rotation around the joints

  (51) and the foot (30) deployed around its articulation (52).

  Stability on the ground is provided by the three-point support on the short feet (24) of the ladder frame and the retractable foot (30), ['the assembly being blocked by the opening of the compasses (41) and (42). The uprights (61) and (62) are raised, and the protective gallery is closed on the front, parallel

  at dimensions (12) and (13) by placing the bars horizontally-

  guardrails placed and stopped on the cleats (56).

  For folding back into the transport and storage position, the bars (63) are folded down along the uprights (62), and these uprights are themselves tilted along the sides 112) and (13) of the platform; the upright (61) is folded down on the platform along the spacer (14). Then, the compasses (41) and (42) being unlocked, the platform is folded down on the ladder frame by tilting around the articulations (51) while the foot (30) tilting around its articulation (52) passes to the through the ladder frame (20) between the first bar (22) and the crossbar (23) and is folded down along the outer face of the ladder frame, ensuring at the same time the closing and blocking of the folded device (see Figure 2) that can be ensured with a simple link tightening this foot (30) and the amount (61) of the railing now opposite. To ensure better sitting on soft ground, the ends of the short legs (24) and the retractable leg (30)

  can be fitted with fixed or removable pads.

  The watchtower of the invention is a light, solid structure, very stable even on the uneven ground; its reduced size in the folded position and its low weight make its transport very easy; it deploys and folds effortlessly in less than a minute; after use, it

  also organizes with great ease.

  It is understood that the invention relates to a foldable platform structure which was initially designed to respond to a problem of hunting equipment, but that any other use, in its form

  complete or without railing, remains of the field of the invention.

Example

  A watchtower as described above, was built on the model of a triangular platform

  equilateral 1 meter side, with access by a frame-

  fixed ladder width 0.80 m on a cross

  1.15 m fitted with 10 cm short legs at its ends.

  The telescopic arrangement of the feet allows the platform to be placed at least 1 m, maximum at 1.50 m from the ground, allowing a posed shooter to execute a firing shot in complete safety for the other hunters possessed as well as for touts. The railing measures 0.95 m. The three-point support on the ground ensures its stability, even on uneven ground. The object is very light, 25 kg in its realization in iron, 8 kg in its realization in aluminum. It can be transported without problem in any vehicle whose trunk accepts an object of 105 X 110 cm. Its size

  storage is very reduced (storage thickness = 11.5 cm).
