   L'objet de la présente invention est relatif à un système de ver- rouillage ou blocage des éléments d'un mât télescopique d'antenne ou autre; spécialement   à   un verrouillage automatique interne des éléments.- 
En règle générale le blooage des éléments que constituent un mât télescopique d'antenne, s'effectue soit au moyen de vis de pression, colliers de serrage ou clapets   à   ressort; tous les systèmes, actuellement connus, se trouvent   à   l'extérieur des tubes; il en résulte des difficultés;

   perte de temps et danger au montage des dits   mâts.-   
Le but de la présente invention est de remédier à ces   inconvé-   nients. - 
Conformément   à   l'invention, ce système consiste en un double ver- rou pouvant être logé dans le bas de chaque tube, fixé   dans   une position dé- terminée, dans le but de constituer un blocage automatique et instantané des éléments entre-eux, sans qu'il soit nécessaire de visser ou serrero- 
Ce verrou étant, par exemple, constitué par deux cales en acier en forme de V pivotant sur un axe et actionné par   un   ressort afin de les maintenir en placez- 
Le verrou, maintenu en place dans les ouvertures prévues à cet effet dans le tube, garde un ressort bandé;

   ledit ressort ne se   détend   pour éjecter les cales, que,une fois les ouvertures libérées.- 
D'autres détails et particularités'ressortiront de la description   ci-dessous,   donné à titre d'exemple non limitatifs et avec références aux dessins annexés, en coupe verticale axiale.- 
Le verrou représenté   à   la figure I, comporte les deux cales 1 et 2, pivotant sur un axe 3, les deux cales sont éjectées par le ressort 14.

   The object of the present invention relates to a system for locking or blocking the elements of a telescopic antenna mast or the like; especially to an internal automatic locking of the elements.
As a general rule, the blocking of the elements that constitute a telescopic antenna mast is carried out either by means of pressure screws, clamps or spring valves; all the systems, currently known, are located outside the tubes; difficulties arise;

   loss of time and danger when assembling said masts.
The aim of the present invention is to remedy these drawbacks. -
According to the invention, this system consists of a double lock which can be housed in the bottom of each tube, fixed in a determined position, with the aim of constituting an automatic and instantaneous locking of the elements between them, without whether it is necessary to screw or tighten
This lock being, for example, constituted by two V-shaped steel wedges pivoting on an axis and actuated by a spring in order to keep them in place.
The lock, held in place in the openings provided for this purpose in the tube, keeps a spring loaded;

   said spring only relaxes to eject the wedges, once the openings have been released.
Other details and features will emerge from the description below, given by way of nonlimiting example and with reference to the accompanying drawings, in axial vertical section.
The lock shown in Figure I, comprises the two wedges 1 and 2, pivoting on an axis 3, the two wedges are ejected by the spring 14.

Claims

FIG. III shows a lock folded back in its tube 1, engaged in the passage holes 2 - 3, the tube 4 keeps the wedges in place. - FIG. II shows a movable section of the mast with its lock in the guard position. Two cells 1 and 2 are provided on the tube 4 to receive the wedges, maintaining the elements in a determined position. - It should be understood that the invention is in no way limited to the embodiment above and that many modifications, shape or model, could be made to it, without departing from the scope of the present patent application.

1. Internal lock for antenna masts, characterized in that it is located inside the sliding elements. 2. Lock according to claim 1, characterized in that it consists of one or more metal wedges, ejected outwards by means of a spring, in order to constitute an automatic lock for masts. antenna .- 3. Lock according to either of the preceding claims, characterized in that the wedges are ejected from the inside to the outside and kept in the guard position, by the upper tube. <Desc / Clms Page number 2> 4. Internal lock for antenna masts, as described above and shown in the accompanying drawings.
