The lower part and upper part are joined to one another on at least one side using a closure device comprising a resilient snap hook, which is collapsibly attached to one pan and a latching element corresponding to the snap hook on the other part, the latching element being an integral component of the other part. The closure device preferably does not extend beyond the external contour of the apparatus housing to allow a plurality of warning lights to be mounted, transported and erected directly next to one another in a space-saving manner. <IMAGE>
Description
WARNING LIGHT
FOR VISUALLY SAFEGUARDING SOURCES OF DANGER
The invention relates to a warning light for visually safeguarding sources of danger, for example building sites on roads and the like, essentially comprising an optical part for single-sided or multi-sided radiation of light and an apparatus housing for the common accommodation of a current source and an electronic switch arrangement, on which the optical part can be fixed, and which comprises a housing lower part and a housing upper part which can be joined to one another on at least one side by means of a closure device.
Warning lights of this type, which are usually transportable, have an apparatus housing, wherein a current source, preferably dry batteries, are accommodated in the lower part of the housing. An electrical or electronic switch arrangement is situated in the upper part of the housing and is provided to release electronic flashes or to produce a steady light. The optical part, which has at least one Fresnel disc or a reflector disc, is arranged on the upper part of the housing.
The apparatus housing is designed to have two parts, as mentioned, in order to be able to charge or recharge the current sources. The upper part of the housing and the lower part of the housing are usually screwed to one another. This has the disadvantage that an additional tool is necessary and a considerable manual effort has to be made to separate the two parts of the housing from one another or to join them to one another. Other closure devices have therefore been developed which comprise threaded pins on one housing part and provide tommy screws or tommy nuts or knob handles on the other housing part, which should make more or less complex releasing of the two housing parts possible.Closure devices of this type have the disadvantage that they project beyond the external contour of the apparatus housing of the warning light and are impeded by closure devices of a warning light arranged next to it. If in each case one closure device is arranged on at least two opposing sides of the apparatus housing, several warning lights cannot be arranged directly next to one another in a space-saving manner.
It is therefore the object of the present invention to provide a warning light for visually safeguarding sources of danger, in which the housing parts of the apparatus housing can be joined to one another in simple manner, the connection being designed so that it does not project beyond the external contour of the apparatus housing in the locked state, so that a space-saving, direct arrangement of several warning lights next to one another is possible.
The object is achieved in accordance with the invention, in that the closure device comprises a snap hook, which is collapsibly attached to one housing part, and a latching element corresponding to the snap hook in the other housing part, the latching element being an integral component of the housing part.
The closure device preferably closes flush with the apparatus housing in the locked state.
The snap hook has a bead projection directed towards the apparatus housing at its one end and is pivotably mounted in the housing part at its other end.
The latching element corresponding to the snap hook in the corresponding housing part has a trough-like depression for locking reception of the bead projection of the snap hook.
In a preferred embodiment, the bead projection of the snap hook has a preferably virtually circular cross-section, which essentially corresponds to the cross-section of the trough-like depression of the latching element.
In a further preferred embodiment of the invention, the snap hook is arranged on the housing lower part and the latching element is arranged on the housing upper part.
Furthermore, the novel warning light may have one closure device on each of at least two opposing sides of the apparatus housing.
Rapid release or joining-together of the two housing parts is possible as a result of this invention, since the bead projection is pressed over the upper edge of the trough shape of the latching element, the bead projection of the snap hook being resiliently flexible in a certain manner so that it can latch into the trough shape of the latching element or can be released from it. A secure attachment and easy and rapid handling of the closure device is thus ensured.
Since the closure device closes with the external contour of the apparatus housing in the locked state and does not project beyond it, a plurality of warning lights may be mounted, transported and erected directly next to one another in a space-saving manner.
The invention will be illustrated in more detail below with reference to the associated drawings. The drawings show in
Figure 1: the front side of a warning light having a closure device of a first embodiment in sectional view;
Figure 2: a side view of the warning light according to Figure 1;
Figure 3: a partial sectional view of the apparatus housing in a second embodiment.
The main parts of the warning light 1 comprise an optical part 3 and an apparatus housing 5. The optical part has several reflector discs or Fresnel discs 7 and a carrying handle 9. The conventional flash lamps or filament lamps are situated in the optical part 3.
The apparatus housing 5 essentially comprises the housing upper part 11 and the housing lower part 13. The electronic switch arrangement not shown is accommodated in the housing upper part 11, whereas the current sources not shown are situated in the housing lower part.
The two embodiments according to Figures 1 to 3 each have a closure device 15, which is dealt with in more detail below, on two opposing sides of the apparatus housing 5.
The closure device 15 essentially comprises a snap hook 17 and a latching element 19 corresponding thereto. The snap hook 17 is pivotably joined to the housing lower part 13 at its lower end at the point 21, and can be swung away from the latching element 19 to separate the two housing parts from one another, or are swung inwards to join the two housing parts to one another.
The snap hook 17 has a bead projection 23, which is designed to be resilient, at its end lying opposite the pivoting point 21. The latching element 19 has a trough-like depression 25 corresponding to the bead projection 23, the front edge of the troughlike depression 25 being disposed higher by a small amount than the lower edge of the bead projection 23.
The bead projection 23 of the snap hook 17 can be forced into engagement with the trough-like depression 25 of the latching element 19 such that the bead projection 23 is moved over the front edge of the trough-like depression 25. This is made possible due to its resilient design.
According to a first embodiment according to Figures 1 and 2, the bead projection 23 is situated directly on the end of the snap hook 17 lying opposite the pivoting point 21. In the second embodiment according to Figure 3, the bead projection 23 projects laterally towards the latching element 19. In both embodiments the bead projection 23 of the snap hook 17 lies in the corresponding trough-like depression 25 of the latching element 19 in the locked state. In the'same manner the snap hook 17 is disengaged from the latching element 19 by swinging it away towards the outside, so that the bead projection 23 of the snap hook 17 must overcome the front edge of the trough-like depression 25 of the latching element 19.
Simple handling of the warning light is ensured as a result of this invention.
