Description

Introduction

[0001] The invention relates to the field of toys. More precisely, the invention relates to a toy set with a small pack size for playing in and with, for example, sand, soil, gravel or water. State of the art and disadvantages

[0002] Sand toy sets have been known for a long time. They are designed for toddlers to play in and with sand and typically include a bucket, a sieve, and other small parts such as a rake, a shovel, sand molds, or even a watering can, which, depending on the design, is suitable for pouring sand or water. Therefore, such sets are also suitable for playing with gravel, soil, or water, which is why the term "toy set" or simply "set" will be used below.

[0003] Such a set is known, for example, from German patent application DE 17 58 561 U. According to this proposal, the sieve also serves as a lid for the bucket, which in turn is designed to hold the small parts. To prevent longer small parts (rakes, shovels) from further increasing the already considerable overall height of the bucket, the sieve has separate openings for the handles of these small parts, which can protrude accordingly. However, this ultimately also leads to an increase in the overall height of the set.

[0004] To attach the lid to the top of the bucket, the printed document suggests separate locking elements, which, however, complicate the construction and increase its cost, and – depending on the specific design – may also pose a certain risk of injury, especially for small children.

[0005] Patent DE 40 17 349 C1 therefore proposes replacing the locking mechanisms with a simple handle, which can be detachably attached to the top edge of the bucket by at least one of its two ends. If both ends are attached to the outer top edge of the bucket, it can also be carried using the handle. In particular, the handle is dimensioned so that it can encompass a watering can serving as a lid for the bucket, holding it securely in place. This protects small items stored in the bucket from loss, and also makes attaching the watering can to the bucket easy, even for small children. However, the overall height of the set remains considerable.Furthermore, the bucket naturally has a relatively large volume; while this is desirable for its intended purpose, it also means that a bucket completely filled with small parts will only rarely be offered. The user will then hardly notice if one of the small parts is lost due to unintentional misplacing, which happens frequently, however, since the bucket will still have a certain residual level after the game has ended, roughly corresponding to the original fill level.

[0006] Publication FR 1072064 A discloses a sand toy set comprising a rigid bucket, a sieve that can be inserted into the top, and several small parts (rake, shovel, molds). These are placed on top of the sieve or inserted into designated tubular guides in the sieve, protruding well above the bucket.

[0007] A foldable bucket with a matching lid is known from publication WO 94 / 24002. While this bucket can be folded to save space, naturally this leaves no interior space for additional items, which would then have to be transported separately.

[0008] Document US 2015251808 A1 discloses a toy set for children which has all the technical features set out in the preamble of claim 1. Problem of the invention and solution

[0009] The invention is therefore based on the objective of providing a toy set that avoids the disadvantages of the prior art.

[0010] According to the manufacturer, the toy set should have a small pack size when folded and be easy to store. It should also be highly secure against loss due to misplacing the components.

[0011] The problem is solved by a toy set according to claim 1. Advantageous embodiments can be found in the dependent subclaims, the following description, and the figures. Description

[0012] The invention relates to a toy set or, in short, a "set" of the type described above, which is designed and intended to be used by children for playing in and with, for example, sand, soil, gravel, but also water.

[0013] The set includes a bucket, a lid covering the top edge of the bucket, and several small parts designed to be stored inside the bucket. These small parts are designed, for example, for digging and shaping sand.

[0014] The lid (in a top view) preferably has a profile that roughly corresponds to that of the bucket or slightly exceeds it (for example, by 1 cm), so that the lid can neither fall into the bucket nor protrude unnecessarily far beyond its sides. The lid's primary function is to contain the small parts transported inside the bucket; therefore, it is neither necessary nor excluded that the lid must be (essentially) airtight or watertight.

[0015] The small parts are preferably small enough to fit inside the bucket when covered by the lid. It is conceivable, though less preferred, that at least one small part protrudes from the bucket, the area between the bucket and the lid, or from the lid itself at a designated location. A small part can also consist of several individual parts that are, for example, nested together, hooked together, connected by a hinge, or otherwise joined or connected. It is also conceivable that an individual part can be connected to different other individual parts, for example, a handle with different tools. Furthermore, a small part can also be extendable (telescopic), particularly its handle area.

[0016] The set according to the invention is characterized in that the bucket is designed as a collapsible bucket, wherein even in the folded and covered state of the bucket the small parts can be accommodated in it without the height of the set resulting from the folded and covered bucket and lid increasing again.

[0017] A collapsible bucket of the type according to the invention is a container which has at least one flexible area or at least one flexible element circumferentially in its outer surface, wherein the outer surface typically tapers from the opening towards the bottom. The flexible area or flexible element allows the smaller wall segment to be pushed / folded into the space within the next larger wall segment, whereby the flexible area or flexible element reduces the angle between the two wall segments from, for example, 180 degrees (unfolded position, smooth wall transition) to almost 0 degrees (folded position, sharp bend in the wall transition). Preferably, the bucket has the shape of an inverted truncated cone or pyramid. The tapering is dimensioned such that the individual wall segments do not obstruct (block) each other when pushed together, but can be laid against one another.

[0018] Furthermore, even when the bucket is folded and covered with the lid, at least one small part can be stored inside. Therefore, the overall height of the set remains low despite the small part(s) being stored inside the bucket.

[0019] According to the invention, at least one of the small parts is adapted to the internal geometry of the interior space created when the bucket is folded and covered with the lid. This means that the small part is shaped and dimensioned so that it utilizes the interior space without protruding beyond it. This ensures that the bucket can contain the small part even when folded and covered, without expanding its folded shape. Preferably, all small parts are shaped and dimensioned accordingly.

[0020] Additionally, at least one of the small parts is adapted to the geometry of at least one other small part. This means that one small part takes into account the geometry of one or more other small parts, which are then preferably to be inserted into the interior in a specific position in order to optimally utilize the available space without interfering with each other.

[0021] At least one small part is designed to fit both the volume defined by the inner walls of the folded and covered bucket, and the other small part(s) located inside.

[0022] The invention thus avoids the disadvantages known from the prior art.

[0023] By using a collapsible bucket, the overall height of the set is significantly reduced when stored (bucket folded). Compared to a conventional toy bucket in known toy sets, which typically has a height of 20 to 40 cm (or 5 to 10 cm in some cases) and a diameter of 15 to 35 cm (or 5 to 10 cm in some cases), the collapsible bucket according to the invention, when folded, has a height of typically only a few centimeters (e.g., 3 to 8 cm), while the diameter remains large. When extended and ready for play, however, it has a height comparable to conventional toy buckets (e.g., 20 to 40 cm).

[0024] At the same time, the ability according to the invention to accommodate the at least one small part into the interior of the folded bucket ensures that, despite the low overall height achieved in the stowed state, no small part is lost or separated, i.e. . The sand must be carried outside the interior, between the bucket and the lid. This has the further advantage that small parts, typically contaminated with sand, do not scatter it unintentionally, at least when the bucket is upright, as any sand that falls inside remains until the set is used again. Another important advantage is that, despite the small parts inside, the set is significantly lower in height than conventional sets, which is beneficial for transport, storage, and shipping.

[0025] The lid on the bucket ensures that no small parts can be lost when the set is not in use.

[0026] Various embodiments of the invention are described in more detail below.

[0027] According to a preferred embodiment, the set comprises a plurality of small parts which are of identical, but preferably at least partially different, type.

[0028] In a further embodiment, one of the small parts can be inserted into the folded bucket in such a way that its tip and handle end rest against or on opposite, and preferably inner, points on the upper edge of the bucket. This means that the small part has a length approximately equal to the diameter of the bucket at its upper edge, allowing the small part to be as long as possible. Because it rests against the bucket, its position is also fixed; that is, it cannot be accidentally positioned so that it protrudes into the bucket, making it impossible to fold and / or cover it. Incorrect positioning is thus easily recognizable.

[0029] Preferably, the bucket has at least one recess or indentation in the area of ​​its upper edge, into which the tip or handle end of one of the small parts can be received. Thus, the bucket provides a kind of marker that facilitates the correct insertion and positioning of the respective small part. Furthermore, the overall height of the set is reduced by the depth of the recess or indentation (measured along the set's height). Particularly preferably, the bucket has corresponding recesses for both the tip and the handle end.

[0030] In another embodiment, one of the small parts has a longitudinal recess on its back side, into which the handle of another small part can be at least partially inserted. For example, the first small part could be a shovel, which has a recess on the back of the actual tool part that extends from the tip towards its handle. The handle, for example, of a rake aligned parallel to the tool's longitudinal axis, can be partially or completely inserted into this recess. This provides, on the one hand, a guide for the desired, space-saving, and correct folding of the small parts; on the other hand, it reduces the height of the folded small parts as measured according to the definition above, which in turn results in an even lower overall height of the set.

[0031] The predetermined optimal "assembly" of the set for space-saving storage offers a further advantage: If a small part is not installed in its designated place, this is immediately noticeable. Consequently, a user will immediately search for the missing part in order to complete the set. Thus, the set according to the invention also exhibits a high degree of security against loss due to accidentally leaving components behind, similar to a puzzle where a single missing piece only becomes apparent when it is assembled into a complete picture.

[0032] For example, the set includes a shovel, with the bucket having a first recess for the tip of the shovel and a second, opposite recess for the handle. Therefore, the shovel is automatically inserted in the correct position when the set is assembled, and the overall height of the set is not increased. If the shovel were inserted incorrectly, this could, for example, result in the lid and bucket no longer fitting together; a faulty assembly would therefore be immediately noticeable.

[0033] In a preferred embodiment, the set includes a rake. The rake has a curvature at its tooth-bearing tip that corresponds to the curvature of the inner upper edge of the bucket, so that when the rake is placed in the bucket, its outer surface rests against the inner surface of the bucket. In this way, the rake can be as long as possible without extending beyond the circumference of the bucket. Furthermore, its position is fixed such that its longitudinal axis essentially intersects the longitudinal axis of the bucket (which then has a round cross-section).

[0034] In another embodiment, the rake has an even number of teeth, resulting in a central gap between the teeth. The handle of another small part, such as a shovel, can be inserted into this gap. The handles of the rake and the other small part, each with its own handle, are then parallel to each other when the rake is placed or inserted onto the other small part in such a way that the longitudinal axis of the handle of the other small part runs through the aforementioned gap.

[0035] Preferably, the height of the tines on the rake corresponds to the distance between the bottom of the folded bucket and the inside of the lid covering the bucket. This means that the height of the teeth is dimensioned so that the rake, when folded, fits precisely into the space between the bottom of the bucket and the lid, thus allowing the rake to have the greatest possible tine height and also permitting the set to be stored according to the invention.

[0036] In another embodiment, the lid is designed as a sieve or a watering can. It then serves not only to prevent the contents of the bucket from spilling, but also as an additional toy. The openings in a sieve can be relatively large without posing a risk of small parts falling out of the bucket. A watering can, to fulfill its purpose, already has a closed bottom, the outside of which faces the inside of the bucket.

[0037] It is also possible that the set includes a multi-part lid, for example a sieve onto which a watering can is placed. Both together, by definition, constitute a lid within the meaning of the invention.

[0038] In another embodiment, the bucket has laterally projecting protrusions at its upper edge for attaching a handle. The handle is thus connected to these protrusions, for example, by being pushed on, screwed on, or tied to them. For this purpose, the handle has corresponding holes at both ends. The protrusions are an integral part of the bucket.

[0039] In another embodiment, the bucket has holes in the area of ​​its upper edge for receiving projections of a handle. In this embodiment, the projections are part of the handle and are located at its ends. They can be inserted into correspondingly provided holes to attach the handle to the bucket, in which they are preferably mounted to rotate freely.

[0040] Both of the aforementioned embodiments are essentially equivalent; the following explains how the lid interacts with the projections belonging to the bucket or the handle.

[0041] Accordingly, the lid, analogous to the projections, provides recesses to allow the projections to pass through. Without these recesses (recesses in the lid wall towards the bottom), the lid wall would rest directly on the projections and, while it could cover the bucket, it would not be able to securely close it by enclosing it. The recesses in the lid thus provide space for the projections of the bucket or handle. Depending on the design, there may be, for example, two projections and at least two recesses positioned at the corresponding location on the lid, but more recesses are also conceivable, such as four, six, or eight.

[0042] It should be added that the bucket may also include further projections, which are likewise arranged at the aforementioned upper edge and follow the pattern of the recesses. Such additional projections can, for example, serve as stops for the handle, preventing it from tipping down too far.

[0043] Preferably, the recesses comprise inclined planes on which the lid can slide along the bucket by contacting the projections and rotating about its longitudinal axis. This means that when the lid is placed on the bucket, the lid will slide along the ramps by the interaction of the projections (e.g., .The lid rotates (pins) along the angled recesses (sliding tracks), similar to a cam mechanism, and—provided sufficient gentle pressure is applied toward the bucket—continues to move toward it. The angled recesses thus serve as tracks along which the lid slides on the projections. The rotation ends when the projections contact the ends of the angled sections (near the bottom of the lid). In this position, the lid is seated as far as possible on the bucket. The contour of the angled sections can be wavy or, for example, sawtooth-shaped (symmetrical or asymmetrical).

[0044] It is particularly preferred that the area extending beyond the top edge of the bucket has elastic claws pointing towards the top edge of the bucket, located on points of the lid wall positioned between the recesses. These claws allow the lid to be self-retainingly attached to the top edge of the bucket, which then forms a corresponding collar. It is understood that the claws and / or the material surrounding them must possess a certain degree of elasticity to enable the necessary snapping action. Alternatively or additionally, the top edge of the bucket can also exhibit a certain degree of elasticity, at least in the corresponding areas of the collar. At least two opposing claws should be present. However, it is also possible to provide such claws at some or all of the points.

[0045] Preferably, the recesses also serve as grips, making it easier to lift the lid off the bucket.

[0046] In another embodiment, the bucket and / or at least one of the small parts have markings for the correct sequential assembly of the set. Such markings, which can be numbers or symbols for the respective small parts, facilitate the correct assembly of the set, thus allowing it to be carried out more quickly.

[0047] In a preferred embodiment, the set consists at least partially of a material from the group of bio-based plastics, such as, in particular, bio-PET (polyethylene terephthalate derived from renewable sources) or bio-PVC (polyvinyl chloride derived from renewable sources). The advantage of a set consisting partially or entirely of such a material lies in the favorable CO2 balance during the production of the plastic-based toy.

[0048] According to another preferred embodiment, the set consists at least partially of biodegradable plastics such as PLA (polylactic acid) or PHA (polyhydroxyalkanoate). A set made partially or entirely of this material offers the advantage that it can be disposed of at the end of its service life without any adverse environmental impact. A further advantage is that accidentally lost and misplaced small parts also decompose completely in the medium term, thus preventing the risk of environmental pollution from harmful microplastics. Preferably, the material is selected such that the set, under normal use, i.e., . If it is not exposed to moisture for more than a few hours and is stored dry after use, it will not decompose. Character description

[0049] The invention is explained below using figures as examples. Figure 1a schematic cross-section through an unfolded collapsible bucket; Figure 2 the same collapsible bucket, but in its folded state; Figure 3 a perspective exploded view of an embodiment of the set according to the invention; Figure 4 the set of Fig. 3 in the compound state; Figure 5 the same set in a side view; and Figure 6 the same set in a section view.

[0050] In the Figure 1 Figure 1 shows a schematic cross-section through an unfolded collapsible bucket 10. This bucket comprises three elements: a substantially rigid (cross-hatched) base element 16 with bucket bottom 14, an equally rigid top element 17 with top edge 11, and a flexible element 18 (dotted) arranged between them. By applying compressive forces F in the direction of the thick arrows, the top element 17 and the base element 14 are pushed together. ( Figure 2 );The flexible element 18 reverses itself. As can be seen immediately, the height of bucket 10 has been reduced to approximately one third.

[0051] The process is of course reversible; by pulling on the appropriate points, bucket 10 is unfolded again, so that it once again fits in Fig. 1 takes on the shown form.

[0052] Figure 3 Figure 1 shows a perspective exploded view of an embodiment of the set according to the invention. This set comprises a folded bucket 10, a lid 20, and several small parts 31, 32, 33, 34, and 35. In this case, small part 31 is a shovel, small part 32 is a rake, small part 33 is an ice cream scoop, and small parts 34 and 35 are ice cream cones, each preferably made of plastic.

[0053] How Figure 4 and Figure 6As shown, even when the bucket 10 is folded and covered with the lid 20, all small parts 31, 32, 33, 34, 35 can be accommodated in the interior 12, which extends between the bottom of the bucket 14 and the inside 21 of the lid 20.

[0054] This is achieved by adapting the small parts 31, 32, 33, 34, 35 either to the internal geometry of the interior space 12 resulting when the bucket 10 is folded and covered with the lid 20, and / or by adapting them to the geometry of at least one other small part, i.e., to each other. In the illustrated embodiment, the adaptations are as follows (see figure). Fig. 3 ): The small part 31, designed as a shovel, can be inserted into the folded bucket 10 in such a way that its tip 31A and handle end 31B rest on opposite, inner points of the upper edge 11 of the bucket 10.

[0055] The bucket 10 provides a recess 13 in the area of ​​its upper edge 11, in which the handle end 31B of the shovel 31 can be received. The recess 13 also serves as a marker for the correct positioning of the shovel 31.

[0056] The shovel 31 has a longitudinal recess on the rear side 31D of the actual tool part (shovel), extending from the tip 31A towards its handle end 31B. The handle 32C of a rake 32, aligned parallel to the shovel with its longitudinal axis, can be partially inserted into this recess (see figure). Fig. 6 ).

[0057] The rake 32 has a curvature at its tooth-bearing tip 32A that corresponds to the curvature of the inner upper edge 11 of the bucket 10, so that when the rake 32 is placed in the bucket 10, the teeth rest against the inside of the bucket 10. Furthermore, the rake 32 has an even number of teeth, resulting in a central gap 32D between the teeth. The handle 31C of the shovel 31 can be inserted into this gap, allowing it to be of maximum length.

[0058] Furthermore, the height of the toothed tip 32A of the rake 32 corresponds to the distance between the bottom 14 of the folded bucket 10 and the inside 21 of the lid 20 covering the bucket 10, so that the rake 32 fits precisely into the space between the bottom 14 and the lid 20 when the bucket is folded. In this example, the unfolded wall elements of the bucket 10 slightly reduce the height. The teeth could also be longer by using a different shape.

[0059] The features described above mean that the overall height of the assembled set (with the bucket folded to 10) can be significantly lower, and that the absence of a single small part is immediately noticeable.

[0060] In the illustrated embodiment, the lid 20 is designed as a sieve and thus also provides a toy function. The openings of the sieve are so small that the retention function is not impaired.

[0061] To easily connect bucket 10 and lid 20, bucket 10 has these laterally projecting protrusions 15 in the area of ​​its upper edge 11 for attaching a handle 19 (beginning of which is indicated by a dashed line). ( Fig. 4 ). Alternatively, the projections 15 are located at the ends of the handle 19 and are part of it, and are inserted into corresponding holes in the bucket 10. ( Fig. 3 ).Similarly, the lid 20 provides recesses 22 to allow the projections 15 to pass through. In this case, there are two projections 15 and eight recesses 22. Thus, the lid 20 can be placed on the bucket 10 in eight different positions. The recesses 22 include slopes 22A. ( Fig. 5 ), The lid 20 can slide along the projections 15, rotating about its longitudinal axis L in the direction of the bucket 10. The inclined surfaces 22A of the recesses 22 thus serve as tracks along which they can slide on the projections 15. The rotation ends as soon as the projections 15 reach the end of the inclined surfaces 22A (near the bottom of the lid) (in the image, at the top; the horizontal area between the inclined surfaces 22A). The contour of the inclined surfaces 22A is undulating.

[0062] Furthermore, the area of ​​the lid 20 extending beyond the top edge 11 of the bucket 10 has elastic claws 23 pointing towards the top edge 11 of the bucket 10. ( Fig. 6 ). These are located at points on the lid wall arranged between the recesses 22. The lid 20 can be self-retainingly attached to the upper edge 11 of the bucket 10 by means of these claws 23. The upper edge of the bucket 10 has a corresponding collar that can be at least partially engaged by the claws 23. The claws 23 are designed to be elastic. Thus, after being placed in any position, the lid 20 is first set into a rotational movement, if necessary, which aligns it so that the projections 15 lie between the recesses 22, so that contact with the bucket 10 is then established and maintained by means of the claws 23.

[0063] The recesses 22 also serve as grip recesses, which make it easier to lift the lid 20 off the bucket 10. Reference symbol list
