摘要:
A battery powered lamp unit in the form of an electric lamp integral with a compartment to contain at least one electric battery to power the lamp, or electrical circuit whereby the lamp is powered by the battery, and a tubular supporting container having an open end into which the electric lamp is insertable for support thereby with the container surrounding the compartment and the lamp projecting beyond the open end. Engageable elements on the unit and interior of the tubular container are arranged such that the elements engage one with another some distance within the container from the open end when the unit is inserted so as to prevent removal of the unit. The interengaged elements can be unlocked by a key which can be inserted into the tubular container.
摘要:
A base to maintain an element in an upstanding state, the base comprising a container formed of moulded plastics material and having mounted thereon or being arranged to be engaged by an element to be maintained upstanding above the base. The container has a lower part to stand on a floor or ground surface, and an upper covering wall forming at least one upwardly open recess or tray. The base has a shape enabling it to stand stably and to increase the stability or resistance to upset the base so as to maintain said element upstanding when the base is in use, the base can be ballasted by liquid, slurry, particulate or lumpy material introduced into the interior of the container through an access opening leading thereinto and/or by ballast loaded into the tray.

@ Disclosed is a method of supporting a road traffic sign post (20) in which a lower sleeve portion (22) of the post (20) is embedded in the ground and secured therein by concrete (23), an interference fit tubular adaptor (1, 11) is driven into the sleeve (22) to provide a predetermined length of adaptor extending from the sleeve and the upper post portion (21) driven into the projecting portion (3, 13) of the adaptor (1, 11) so that the upper end of the sleeve and lower end of the post are in an abutting relationship. The adaptor (1, 11) is required to be weaker than the upper portion (21) of the post (20) in order that it will fracture or bend along a line between the abutting ends of the upper portion (21) and sleeve (20) in event of being hit, by for example, a car. The adaptor (1, 11) may have an outwardly directed flange (4,14) to determine the extent of penetration into the sleeve (22) and post (21), and outwardly directed chevrons (15, 16) at the ends to provide «lead-in» portions. The impact strength of the adaptor (1, 11) is predetermined by controlling its wall thickness or providing lines of weakness such as a groove or lines of holes (7).
摘要:
A road edge marker comprising a reflector support divided into two aligned portions joined together by means of a hinge which allows the two portions to shift in case of collision. The hinge consists of sleeves fixed to said portions, connected to one another by an elastic member, such as a spring or a caoutchouc tube, which brings them back to their original position.

Mit der Erfindung wird ein Verkehrszeichenträger beschrieben, der ein Trägerrohr für ein Verkehrszeichen o.dgl. aufweist, das über eine Zwischenhülse mit einer fest im Boden verankerten Aufnahme (Rohr- oder Massivstück) zusammengesteckt ist. Die Zwischenhülse besteht aus zwei ineinanderliegenden vorzugsweise konischen Rohren, von denen das außere Rohr etwa in der Mitte seiner Länge als Wellrohr ausgebildet ist. Bei kleineren Verbiegungen läßt sich das Verkehrszeichen ohne weiteres wieder aufrichten, ohne daß die Funktion beeinträchtigt ist. Bei einer starken Beschädigung wirkt das äußere Wellrohr als eine Art Fang riemen und verhindert das Abreißen an der Sollbruchstelle. Durch die Erfindung ist es möglich, beschädigte Verkehrszei chen einfach auszutauschen bzw. gegebenenfalls ohne Er neuerung von Teilen wieder instandzusetzen.
摘要:
L'invention a pour objet des dispositifs d'accouplement élastique pour assembler bout à bout coaxialement deux tubes. Un dispositif selon l'invention comporte une pièce (3) portant un embout mâle (3a) qui est fixée à l'extrémité d'un premier tube (1a) et une deuxième pièce (4) portant une portée femelle (4a) qui est fixée à une extrémité d'un deuxième tube (1b). Les deux pièces sont traversées par un alésage axial (3b, 4b) à travers lequel passe un câble (5) portant deux bouts de tige filetée (6,7) sur lesquelles sont engagés deux disques perforés (12 et 13) prenant appui chacune sur un ressort (10, 11) qui est mis en tension par le serrage d'un écrou (14,15). Une application est la construction de supports tubu laires verticaux exposés aux chocs de véhicules, notamment de barrières de parkings privés.
