The invention relates to a holding device for articles of fireworks, in particular for skyrockets. However, the holding device may be configured for virtually any other variants of pyrotechnic articles, such as bomb tubes and pyrotechnic pinwheels (also known as whirligigs or spinners).
It is common practice to launch skyrockets or bomb tubes from auxiliary devices, for example by means of free-standing glass bottles or glass bottles held in crates or from street gullies. In the absence of such makeshift devices, skyrockets are also launched from the hand or are stuck into lawns or snow piles for this purpose. Furthermore, pyrotechnic pinwheels are attached to house walls and trees and are burned down while held in this fashion.
All of these methods are susceptible to malfunctions and faults. In particular, they may present a risk for the individuals executing these actions and for bystanders. For example, glass bottles used for this purpose are easily blown over due to their small base or may topple over due to uneven weight distribution of the articles of fireworks or may lack stability due to adverse ground conditions. For this reason, one frequently reads reports of damage to humans, animals, objects, and trees after fireworks are lit. There is statistical evidence of the fire risk due to uncontrolled or incorrectly used articles of fireworks.
Based on this prior art, it is the object of the invention to create a holding device for articles of fireworks, in particular for skyrockets, that reduces the risk of injury when lighting fireworks and can be manufactured easily and inexpensively.
The invention achieves this object by means of the characteristics of claim 1. Further embodiments of the invention are revealed in the dependent claims.
The holding device according to the invention comprises an engagement part, which in turn is configured for receiving an article of firework to be lit and/or which is connectable or connected to a top part, whereby the top part is configured for receiving an article of firework to be lit. The engagement part according to the invention is configured for mounting the entire holding device on the top side of a sufficiently stable carrier device. In the context of the present specification, “sufficiently stable” is to be understood in the sense that the carrier device must be configured such that it is capable of absorbing the forces occurring during the lighting of the fuse and during the lighting and setting off the article of firework, without the carrier device tilting together with the holding device mounted therein. This mitigates the risk induced by fireworks for individuals in the proximity. In particular, the articles of fireworks that are to be held for burning may be skyrockets, bomb tubes or pyrotechnic pinwheels.
According to an embodiment of the invention, the carrier device may comprise a plurality of parallel, interconnected, vertically oriented tubes whose end faces form the top side of the carrier device. Such a carrier device may be manufactured specifically for the holding device according to the invention.
According to the invention, a fired base body of a firework battery may be used as a carrier device for the holding device, and/or the engagement part of the holding device may be configured such that the engagement part of the holding device can be inserted into the vertically oriented tubes of a base body of a burned-out firework battery, thereby securing the holding device in the carrier device in a sufficiently stable manner.
According to a preferred embodiment, the engagement part comprises a support flange for resting on the top side of the carrier device in the mounted state of the holding device on the carrier device, wherein at least one holding means is provided on a bottom side of the support flange, the means being configured to engage with at least one recess in the top side of the carrier device. The support flange is configured such that its preferably at least sectionally planar bottom side rests on the top side of the carrier device. The at least one holding means thereby engages with at least one recess in the top side of the carrier device, such that the holding device is secured against tilting.
According to an embodiment of the invention, the at least one holding means is configured in a clip-like manner, wherein the at least one holding means comprises at least one clip having two resiliently flexible arms abutting against a respective inner wall of the at least one recess in the mounted state and applying a force thereto, wherein the two force vectors preferably have components directed in opposite directions.
For example, the at least one holding means may be configured such that it engages with two immediately adjacent tubes of the carrier device.
Hereby, the two arms of a holding means embodied as a clip may be configured and arranged such that they apply a force onto inner walls, facing each other, of two immediately adjacent tubes.
As a matter of course, the at least one holding means may also be configured in any other manner that allows to suitably secure the engagement part in the carrier device. For example, a mandrel extending downwards may be provided, on the outer wall of which a plurality of, for example three, spring-like arms are arranged. The mandrel may then engage with a recess, for example with a tube interior.
The at least one holding means may also be embodied as a slightly tapered mandrel, whose diameter in the region underneath the support flange substantially corresponds to the inner diameter of a corresponding recess in the or to the inner diameter of a tube of the carrier device. This variant may be advantageous if the holding device according to the invention is sold together with a firework battery that is used as a carrier device for the holding device after lighting and setting it off. This entire arrangement may then be used for lighting and setting off further articles of fireworks.
According to an embodiment of the invention, the engagement part may comprise a receptacle for an article of firework, in particular for a bomb tube or a pyrotechnic pinwheel. In such an embodiment, the holding device according to the invention does not need an additional part, in particular any top part.
The receptacle may, for example, consist of a mandrel or pin extending vertically upwards, onto which a pyrotechnic pinwheel may be stuck. The pyrotechnic pinwheel may then rotate about the extension formed by the mandrel or pin. The mandrel or pin may also be releasably connected to the remaining engagement part, such that it may be attached as needed.
The receptacle may also consist of a circumferential wall that forms, together with the bottom formed underneath by the top side of the engagement part, a receiving space for receiving a bomb tube. Of course, instead of a circumferential wall, a plurality of upwardly protruding extensions may also be provided, between which the receiving space for a bomb tube is formed in turn. In both cases, the bomb tube may be secured with its longitudinal axis perpendicular to the bottom of the engagement part, such that there is no risk of the bomb tube tipping over when it is lit and the lit article of firework endangering or even injuring people in the vicinity.
According to another embodiment of the invention, the holding device comprises a top part, wherein the top part is connected to the engagement part or is connectable to the engagement part without tools or wherein the top part and the engagement part are connectable by means of a connecting part without tools, preferably releasably. This results in the advantage of a smaller packing volume. When in use, the holding device may be assembled quickly and easily. The releasable connection of the individual parts may also be achieved by means of snap-lock connections, such that a disintegration of the holding device during use is safely avoided.
The connecting part may have a rod-like or tube-like shape and preferably consist of a plurality of elements that can be connected without tools. In particular for holding skyrockets, the connecting part has to be long enough such that the top part of the holding device is at such a height that the guide stick of the skyrocket does not stand up on the ground or on the top side of the carrier device and thereby the skyrocket is not held securely in the holding device.
In particular, the top part may comprise a receptacle for receiving one or more skyrockets. The receptacle for each skyrocket may comprise a tubular receiving part for the guide stick of the respective skyrocket, wherein the tubular receiving part preferably has an inner cross section such that a top part of the skyrocket abuts against the upper end face of the tubular receiving part in the inserted state of the skyrocket.
According to an embodiment, the tubular receiving part may have an upwardly, preferably conically, widening shape, wherein the conical widening is preferably dimensioned such that the upper end of the wall of the tubular receiving part prevents a fuse of an inserted skyrocket from abutting against the outer wall of the tubular receiving part. This facilitates lighting the fuse.
On the outer wall of the tubular receiving part, a windscreen device may be provided, which creates a wind-screened region, where the fuse of a skyrocket inserted into the tubular receiving part engages. This may facilitate lighting the fuse under windy conditions.
In an embodiment of the invention, the windscreen device may comprise one or two walls that are preferably pivotable about an axis parallel to the longitudinal axis of the tubular receiving part. These may abut against the outer periphery of the respective tubular receiving part during transport of the holding device and/or the top part and may be pivoted and/or bent outwards for use.
The invention is explained hereinafter in more detail by means of the exemplary embodiments illustrated in the figures, in which:
As shown in
Instead of such a burned-out firework battery, any other device that ensures corresponding stability and comprises one or more suitable recesses on its top surface for receiving and securing the engagement part, as described below, may be used. The use of a burned-out firework battery has the advantage, that further use is found for such a waste product in terms of sustainability. It is not necessary to manufacture and purchase a separate carrier device specifically for this purpose.
The holding device 100 comprises an engagement part 112 in its lower region and a top part 114 in its upper region. As illustrated in
The top part 114 and the engagement part 112 may also be directly connected to each other in an integral manner or connected via a connecting part 116 integrally connected thereto. The releasable connection of the top part 114 and the engagement part 112 (either directly with each other or via a respective releasably connected connecting part 116) has the advantage of a lower packing volume for transport.
According to the invention, a top part 114 does not necessarily have to be connected to the engagement part 112. Rather, the engagement part 112 may already be configured on its top face for holding and securing an article of firework, for example a bomb tube or a pyrotechnic pinwheel. With such variants, not discussed in detail herein, where the holding device merely comprises one correspondingly configured engagement part, an extension vertically extending upwards may be provided at the top of the engagement part, in particular at the top of the support flange of the engagement part described below, on top of which extension an article of firework in form of a pyrotechnic pinwheel may be inserted. This pyrotechnic pinwheel is then rotatably held for burning. In addition, the extension may be configured for connecting with a rod-like connecting part (see above) or with a correspondingly configured top part.
According to a further embodiment, not shown, at its top side, in particular at the top side of the support flange, the engagement part 112 may comprise means for holding and securing, respectively, a bomb tube. This may be a circumferential vertical wall, in the interior of which the bomb tube may be received at least with its lower part. Thereby, the bomb tube is secured against toppling over when it is being burned off. Instead of a circumferential wall, extensions vertically extending upwards may be provided.
As can be seen from
The engagement part 112 comprises a support flange 122, as already mentioned above. This support flange, at least in its outer circumferential regions at its underside, may have a planar support surface that rests on top of the carrier device 102 and secures the entire holding device 100 against toppling over. The top of the carrier device 102 may, as shown in
The engagement part 112 is visible in an enlarged perspective view of
As already mentioned above, the engagement part 112, in particular the extension 124 and, if applicable, the reinforcements 126 may be configured such that they already form a holding device 100 for an article of firework, for example a pyrotechnic pinwheel. For example, in case of the variant of the engagement part 112 shown in
In a further variant that is not illustrated, the engagement part 122 may be configured such that at least one holding means for a bomb tube is provided on the top side of the support flange 122, which may also comprise a leg support with a slightly larger diameter than the actual bomb tube. These holding means may, for example, be configured as a closed wall, such that a cup-like receptacle for the bomb tube is formed together with the top side of the support flange 122.
Of course, instead of a closed wall vertical extensions, for example in the form of relatively thin walls, may also be provided, which form a (non-closed) space in between, where the bomb tube may be inserted, whereby a bomb tube inserted between the extensions is secured against toppling over by the extensions substantially extending vertically upwards.
As can further be seen from
The at least one holding means 128 may be embodied as a clip 130 with two resiliently flexible arms 130a. These two flexible arms 130a may be configured such that they contact each other in the initial state in at least one vertical location on the faces facing each other. At their underside, the two arms 130a may comprise ends 130b that are bent away from each other below the lowest contact point (when viewed in the vertical direction), such that an insertion region 130c is formed between the two ends 130b. As explained below, this insertion region 130c may serve to sleeve the clip 130 with the two arms 130a onto a vertical wall in one or more recesses in the top side of the carrier device 102. The clip 130 or the holding means 128 may, as described above, be made of a cold-resistant material that remains sufficiently flexible in the cold, for example of metal or of a cold-resistant, flexible plastic.
As can be seen in
The holding means 128, in particular the clip 130, may also be formed such that both arms 130a only enclose a single wall of a tube 106 in the mounted state. For this purpose, the arms 130a may be dimensioned such that they are able to engage with corresponding gaps between two adjacent tubes 106.
The arms 130a may also be configured such that they do not abut against each other in the initial state, but rather are spaced apart with a predefined distance. In such a configuration, the arms 130a may engage with different tubes 106 or also with gaps between the tubes 106, whereby the distance between the arms 103a in the mounted state is not defined by two immediately adjacent walls (in contact with each other), but rather by the thickness of two walls and a distance therebetween.
The at least one holding means 128 may also be configured in another suitable manner to secure the holding device, in particular the engagement part 112, in a recess in the top side of the carrier device 102. For example, the at least one holding means 128 may also be configured as a conical extension or mandrel extending vertically downward, which engages with the circular cylindrical opening of a tube 106 of a carrier device 102, as illustrated in
Such an embodiment may be particularly advantageous, when the holding device 100 is sold together with a firework battery. The mandrel, in particular its outer diameter, may then be adapted to the respective inner diameter of the firework battery. After it has been burned, this firework battery may then be used together with the respective holding device to safely light further articles of fireworks.
By means of all variants of the holding means 128 described above, if configured and dimensioned appropriately, it can be ensured that the support flange 122 rests with its bottom side on the top side of the holding device and that the engagement part 112 and/or the entire holding device 100, respectively, is secured against toppling over or inadvertent release from the carrier device 102.
The top part is configured as a hollow cylinder in this embodiment of a holding device 100, as also shown in
All of these embodiments offer the advantage that, as shown in
The windscreen means 132 may, as can be seen from
The walls 132a may be made of a flame resistant material, for example of a fireproof plastic or of metal, for example a metal film. The walls 132a may be attached with a vertical portion to the outer wall of the top part 114 below the widening portion 114a, for example by gluing. In an initial state (state at the time of sale), the walls 132a may rest on the outer periphery of the top part 114. In this initial state, the walls 132a may also overlap. For the transition to the operative state, the walls 132a may be pivoted or bent outwards, respectively, until a suitably large gap 134 is present between the outer regions of the walls 132a. To this end, the walls 132a may comprise centered tabs 132b, for example. The tabs 132b may be grasped for unfolding the walls 132a from the initial state and pulled outward in a substantially radial direction with respect to the longitudinal axis of the top part 114.
The inner sides of the windscreen vanes and/or the peripheral surface of the outer wall of the top part 114 therebetween (or the receiving part 240 in case of the second embodiment described below) may have a bright (for example, white or yellow) surface. This allows better visibility of the fuse in a dark environment. The corresponding surfaces may, for example, be luminescent.
As can be seen from
The tubular receiving parts 240 are interconnected via a head plate 242 of the top part 214. The tubular receiving parts 240 extend (when viewed in the assembled state) vertically from the head plate 242 downwards.
As shown in
Each receiving part 240 may have a widening portion in its upper region, as previously described for the holding device 100. Likewise, each receiving part 240 may also comprise the windscreen means 132 described above.
Of course, it is possible to provide any other number of receiving parts 240 for the top part 214 instead of three receiving parts 240. It is also possible to provide, instead of the engagement part 244, a further receiving part 240 configured, as in the first embodiment, to receive the guide stick of a skyrocket and connected to the connecting part 116 in its lower region, whereby the guide stick also engages with the connecting part.
Alternatively or additionally, in an additional embodiment, not shown, the top part may be configured for setting off different types of articles of fireworks. For example, a head plate (such as in the second embodiment of
In the first embodiment described above, the engagement part 112 with the extension 124 extending upward may also serve to secure a bomb tube or any other article of firework, when a corresponding recess is provided at its underside, with which the extension 124 may engage.
In general, the holding device ensures a start or launch angle of substantially 90° with respect to Earth's horizon, as specified by the manufacturers of articles of fireworks shot into the air. The device acts as a tilt protection. It is dimensioned such that tilting or bending by the forces that occur when lighting the corresponding articles of fireworks is avoided, even at higher wind loads.
The clip of the engagement part 112 described above may comprise interconnected arms 130a in an initial state (before first use). For example, the arms 130a may be connected via a link or a small plate that may have a predetermined breaking point. When attaching the engagement part 112 with the clip 130 onto the carrier device 102 (in particular a firework battery), the link or small plate must be disconnected. The holding device reaches its desired end position only after separation of this tangible resistance. The link or the small plate may be configured such that during separation, a sound is generated in addition to the tangible resistance, signaling the operator that the holding device (after the last minor distance to the stop of the support flange 122) is connected securely and correctly to the carrier device.
It is also possible to provide the holding device with a linkage that may be configured above the top side of the support flange 122. This allows varying the firing angle. The linkage may also be configured or arranged such that it enables a rotation of the part of the holding device located above. Thereby, the articles of fireworks may be launched in different directions. Furthermore, this allows compensating gradients of the surface on which the carrier device 102 is located.
