IMPROVEMENT IN STANDS FOR SIGNS AND SIMILAR OBJECTS

Abstract: A sign stand comprises a mast (4) which in one end thereof is connected to a container (6) and in the opposite end thereof supports a sign (5) or the like. At a relatively short distance from the end which supports the container (6) the mast (4) is pivotally connected to a support assembly (1, 2) in such a manner that it can be swung up from a substantially horizontal position to a vertical position. This pivoting movement is effected by introducing preferably water into the container and the weight of the water contributes to keep the mast in said vertical position and to withstand forces caused by for instance wind pressure on the sign (5). The mast is easily lowered by removing the water from the container.

Description: IMPROVEMENT IN STANDS FOR SIGNS AND SIMILAR OBJECTS In connection with stands and other high objects such as masts one desired object is the possibil ity of erecting the stand by means of a simple and inexpensive equipment and another desired object is the possibility of aπschoring the stand or mast rela¬ tive to for instance the ground-level plan in such a manner that it can resist the stresses which wind and other things can exert upon the stand. Frequently it is also desired to rapidly lower the stand and pro- bably move i . Stands for signs frequently are 8-10 meters high. The signs can have a considerable area and the stesses which a sign stand has to withstand as a consequence of for example wind thus can be considerable. Sign stands of conventional design do not meet these requirements but are heavy and difficult to transport and for erec ing or low¬ ering them an equipment which is expensive, slow acting and diffi¬ cult to transport is necessary. Thus the main object of the invention has been to overcome the in- conveniences which are connected with conventional stands and to provide a stand which fulfills the objects referred to. In order to accomplish this and other objects the invention has the characteristics of the patent claims. The accompanying drawing illustrates an exemplary embodiment of the invention and more specifically. Fig. 1 is a diagrammatical side view of a sign stand according to the invention in an erected position while OMPI Fig. 2 is a similar view of the sign stand of fig. 1 but in a low¬ ered position. Fig. 3 finally, is an end view of the sign stand in question. The sign stand illustrated in the drawing comprises a member 1 which is intended for ground contact and which in the illustrated embodiment has the shape of a rectangular frame. From the long sides of the latter there extends braces 2 which at the upper por¬ tion thereof are mutually connected and between theirselves support a horizontal shaft 3» about which a mast k is pivotally mounted. In the embodiment as shown said mast comprises two mutually para¬ llel! elongated elements which at the upper end between theirselves support a sign 5 and the mast is pivotally mounted in such a manner that it may be swung down from the position shown in fig. 1 to the posi ion shown in fig. 2. The mas.t supports In the part thereof which according -to fig. 1 is located beneath the pivot shaft 3 a container 6 which has a cer¬ tain minimum volume. The numeral 7 designates the suspension point of the container. The sign stand now described is transported to the chosen si e and can at this occasion either be assembled or have the parts thereof completely or partly disassembled. When it Is desired to install the stand the support is placed at the desired place and the mast with the container secured thereto is mounted upon the pivot shaft 3 in those cases when the sign stand is not already assembled. By pumping water into the container 6 the mast k is successively erec¬ ted. The container however has such a capacity that a further amount of water may be pumped into it after the mast has reached its verti¬ cal position. In this manner- the sign stand will be able to take up the stresses for which the assembly can be exposed. Owing to the fact that the mast k is not firmly clamped but simply performs a swinging or tilting movement when overloaded for instance by in¬ fluence of eddy-winds on the sign 5 it is further accomplished that it may be dimensioned considerably weaker than otherwise. Raising "BURE OMPI and lowering occurs compared to conventional methods very rapidly and since water normally is available at the site the transports will be more simple and cheap than in conventional methods where the parts of the sign stand, which may be very heavy, have to be transported to the site. It is further obvious that it is very easy to lower the sign stand since it is then only necessary to remove the water which has beein introduced into the container. Raising as well as lowering takes place under fully controllable conditions with successive and for the workers safe movements. Although water in most instances will be the most appropiate medium to introduce into the container any medium giving the same effect may of course be used. OMPI

Claims: CLAIMS 1. Improvement in stands for signs and the like, c h a r a c t e r - I z e d in that it includes an elongated element such as a mast (4), which tn one end thereof is capable of supporting a sign (5) or the like and which adjacent to its opposite end is pivotally connected to a support (1,2) and near to said opposite end has a container (6) which is provided to contain such an amount of a stuff that the container after the introduction of a specific amount of said stuff may raise the mast (4) from a substantially horizontal position (fig.2) to a substantially vertical position (fig.1). 2. Improvement according to claim 1, c h a r a c t e r i z e d in that the container (6) has such a capacity that the weight of the stuff introduced therein is sufficient for withstanding the forces caused by for instance wind forces which act upon the stand. 3. Improvement according to claim !, c h a r a c t e r i z e d in that the stuff consists of water and that arrangements are made for pumping water into respectively pump water out of the container (6) for raising respectively lowering of the mast (k) . k. Improvement according to claim 1, c h a r a c t e r i z e d in that the support consists of a relatively elongated part (1) which may be applied towards the ground level and from which extends two at a distance from each other located upwardly directed parts (2) which support between themselves a horizontal shaft (3) about which the mast (4) is pivotally mounted.
