Description

  The present invention relates to an assembly member and a system comprising such an assembly member. In particular, the assembly member is suitable as a toy assembly member or a toy building block (block), or a toy assembly member or a child assembly kit including a plurality of toy building blocks (blocks). Is suitable.

  Children's wooden blocks have been known for a long time. Corresponding wooden assembly kits usually consist of a number of basic geometric shapes (eg cubes, prisms, spheres, cuboids or cylinders, etc.). In addition, assembly kits are also known in which the columns or seams are provided with holes and can be connected to each other via bolts or screws.

  Aside from children's wooden blocks, generally connected to each other in various styles to build fences, walls, garden edges, furniture, partition walls, movable partition walls, flower beds, plant planters in various configurations Possible assembly members are known and these assembly members can be glued together, screwed together or fastened together, for example.

  The purpose of the present invention is to be creative and flexible, for example, in gardening, furniture making, construction of fences, construction of walls or construction of trade show stands and also when used as toy assembly parts, It is to provide an assembly member that can realize the possibility of new shapes and modeling.

  In particular, this assembly member is suitable as a toy assembly member and as a part of a system or assembly kit with such a toy assembly member, because this assembly member is Harmoniously and comfortably in the hands, driving children into creative play and construction, and using them relatively stably, but at the same time relatively mobile with respect to each other This is because a structure (a wall, a bridge, a tower, or a model other than this) can be modeled.

  Therefore, the assembly member according to the present invention is not only suitable for the construction of rigid straight structures or structures having a right angle, but is very flexible in the construction, and connects a plurality of assembly members. After being put together, the structure can still be movable.

  The invention relates to an assembly member according to claim 1 and to a system or assembly kit according to claim 13 comprising a plurality of such assembly members, in particular a plurality of such assembly members for children. Further advantageous configurations of the invention are the subject matter of the dependent claims.

  The assembly member according to the invention is arranged such that when two or more such assembly members are placed side by side, they are harmoniously put together and joined together, and the first or second circle of the assembly member. It is characterized in that the plate area engages in the concave arch of the transition area. The radius of curvature of the transition region is equal to, or at least approximately coincides with, the radius of the first or second disc region, and the first disc region and the second disc region are , Or at least approximately contact so that when the paired assembly members are offset and placed side by side, one assembly member is on one side of the biconcave transition region of the other assembly member And inserted into the concave arch without a seam or at least substantially without a seam, on which side the second assembly member is connected to the first assembly member and, in an ideal case, one of the biconcave transition regions. Along one side, it touches across the entire outer boundary of the transition region.

  The assembly member according to the present invention can be further constructed with an assembly member that is shaped to be equal or different, or when these are joined together to form a wide range of angles between the individual assembly members. In particular, there is the advantage that angles of less than 90 ° and up to 60 ° are allowed or possible. For example, a wall shaped from this type of assembly does not have holes or gaps made at angles below this. Thus, for example, a continuous wall having a buildable angle of less than 90 degrees and up to 60 degrees can be made.

  Especially with the use of so-called “duplexes” and without the need for special angled stones (blocks) or curved stones (blocks), a very wide range of angles (even acute angles) (60 ° Walls with ˜300 °) can be shaped. Nevertheless, this type of wall has a continuous wall surface. These walls therefore allow very versatile shaping, allow very easy construction (and again disassembly), and the bolt-hole system ensures good basic stability .

In a preferred embodiment, the transition region of both concave, in the portion where connecting straight line connecting the first center point M ₁ and the second center point M ₂ traverses the transition region of both concave, narrowing to a point, As a result, the first disc region and the second disc region are in contact at this point, or the biconcave transition region is at least narrow at this point, for example, with a width of about 0, depending on the size of the assembly member. Only 2 to 1.5 mm.

  However, the assembly according to the invention has the advantage that 100% geometric accuracy in production is not necessary at all. Rather, when used as a toy assembly, multiple assembly members with reasonable manufacturing tolerances and slight play are joined, preferably without the use of remarkable forces, even for children. It is even more convenient because they can be bent together, can be easily bent with respect to each other, and can be placed up and down without tilting and without any significant pressing force. As a result, the “double set” can be placed on the “double set” or “triple set” with a little play, and the two “one set” can be placed side by side with a little play. The two “two pairs” arranged in a row can be smoothly connected or bridged by using the “two pairs” or “three sets” placed on one row. Can be done.

  For this purpose, the assembly according to the invention is preferably ground slightly after production, or the edges are rounded and the bolts and / or the openings of the recesses or holes are chamfered. Thereby, especially when a child plays, an assembly member can be easily joined together now.

  Overall, the assembly according to the present invention is harmoniously and pleasantly familiar, and in an embodiment using a solid material such as, for example, beech, it is of high value and has an environmental protection effect. However, metals such as aluminum, glass, plastic, ceramic, gypsum or concrete are also suitable as materials for the assembly members. The assembly according to the invention can also be colored, for example it can be applied with a primary color lacquer, a transparent lacquer, or it can be implemented with natural wood.

  With the assembly according to the invention, children can be creative using only a few types of assembly, or even using only a single type of assembly, for example in the form of “duplex”. Can be driven to play and construction. By using this type of assembly member as an assembly member for toys, walls, bridges, houses, snakes, row-like structures, square or round towers, or other structures can be formed, and these structures Objects are grouped relatively stably up and down via bolts and recesses or holes, but at the same time are relatively movable with respect to each other, and thus construction of straight structures or right-angle structures Not only is it possible, but also rounded or bent structures, or structures that can be deformed after assembly.

In some embodiments of the invention, the first, second and third center points (M ₁ , M ₂ , M ₃ ) are in line. This gives a straight assembly in the form of a straight “triplet”, as shown in FIGS.

In another embodiment of the present invention, the connecting straight line connecting the first center point and the second center point (M ₁ .M ₂ ) includes the second center point and the third center point (M ₁ .M ₃ ). It is perpendicular to the connecting straight line. As a result, an assembly member in the form of an L-shape or a right-angle “triplet” is obtained.

In a preferred embodiment of the present invention, the assembly member is axisymmetric with respect to a connecting line segment connecting the first center point (M ₁ ) and the second center point (M ₂ ), and the first center point ( M ₁ ) and the second bisector connecting the second center point (M ₂ ) are axially symmetric.

In an embodiment of the present invention, the assembly member is axisymmetric with respect to a connecting line segment connecting the first center point (M ₁ ) and the third center point (M ₃ ), and the assembly member has the first center point. The vertical bisector of the connecting line segment connecting (M ₁ ) and the third center point (M ₃ ) is axisymmetric.

  Of course, the above-mentioned concept or principle of construction of the assembly member according to the present invention can be extended to more complex assembly members within the framework of the present invention. In combination, for example, a straight “quadruple”, an isosceles L shaped “quadruple”, a straight “five”, 4: 1 or 2: 3, etc. This is done by combining with a “quintuple”. Besides this, naturally, it is also possible to make a cross-shaped assembly member, for example, an assembly member in the form of two straight “triples” intersecting at the center, a T-shaped assembly member, and Many other forms are possible.

  A basic and simple assembly that implements the concept according to the invention is a “duplex” as illustrated in FIGS.

  Finally, a “single set” (ie, a disc with substantially one bolt and one recess or hole, as shown in FIGS. 3a-3d) can also be used, for example, as a keystone. As such, it has also proved useful in that it can be used to build towers or convex walls for decoration purposes.

  The diameter of the recess and the diameter of the bolt are preferably each in the range of 20% to 40% of the diameter of each disc, in particular about 30%.

  The first region disc and the second region disc, preferably also the transition region, each preferably have a height h at least approximately equal.

  In the case of a “triple” or more complex assembly, a first region disc, a second region disc, a third region disc, and preferably also a transition region and a further transition region are preferred. Are at least approximately equal in height h.

  The surfaces of the first region, the second region, possibly the third region, the transition region, and possibly the further transition region are preferably smooth and / or flat and / or the top bolts; In some cases, the recesses or holes on the lower surface are preferably chamfered or rounded. Thereby, the assembly member can be used comfortably and comfortably and can be used smoothly.

  In some embodiments of the invention, at least one, both or all central bolts are integrally formed with each disk. This eliminates adhesion or grout consolidation, but produces more waste during manufacture.

  In another embodiment of the invention, at least one, both or all central recesses are formed as through holes in each disc region. In this case, at least one, both or all bolts are then affixed to such a through-hole or, inter alia, inserted via press-fitting.

  The first radius r is preferably 10 to 30 mm, in particular 15 to 25 mm, for example about 20 mm, for a toy assembly. The height h of the disc region is preferably in the range of 15 to 25 mm, for example, about 20 mm in the toy assembly member.

  The central bolt and the central recess are preferably sized so that they can rotate smoothly and with little play when the bolt is engaged in the recess.

  The assembly in duplicative form (see FIGS. 1a-1d) generally has an outer profile similar to a bicycle chain link plate, with a short transition area and a radius of curvature selected according to the invention. Yes.

  This biconcave transition region or further biconcave transition region is generally very short in the direction connecting the center points of adjacent disc regions and the width in this direction in all embodiments of the invention. However, it should be emphasized that it is preferably 0 or nearly 0, so that adjacent disc regions are in contact, or in any case only a small distance away from each other.

  The modeling principle of the assembly member according to the present invention or the "one-piece" modeling principle is not only suitable for toy assembly members, but also for general assembly members such as wood, concrete or stone assembly members. For example, it can be used to provide furniture such as shelves, components for trade show stands, partitions, walls, fences, garden edges or curbs. For this purpose, the sizing of the assembly can be adapted accordingly, maintaining the above-mentioned proportions, and the appropriate material (for example concrete) can be selected for each use. In the case of use as a general assembly member of this kind, it is possible to completely or partially not provide bolts and / or recesses in the assembly member as required.

FIG. 1 b is a view of the assembly member 10 shown in FIG. 1 a as viewed from below. 1c is a side view of the assembly member 10 shown in FIG. 1a, and FIG. 1d is a perspective view of the assembly member 10 shown in FIG. 1a.

The assembly member 10 is a plan view, the first region 1 (which includes the center point _{M 1,} with a radius r, for example 21 mm, the height h is, for example, a disk shape of 20 mm), a second region 2 (which is a disc shape with a center point M ₂ and a radius r equal for example 21 mm and a height h equal for example 20 mm).

Regions 1 and 2 each have a round central recess or hole 14 or 14 'that passes through central points M ₁ or M ₂ and has a diameter of, for example, 15 mm, each of which has one round central bolt 13 · 13 'is inserted, in particular affixed or pushed in. These bolts 13, 13 ′ are in the first or second region 1, 2, in the holes 14, 14 ′, preferably each about half the height h or slightly less, or for example holes Extends from 30% to 40% of the depth of 14.14 'so that the holes 14.14' can enter and exit from the lower surface 12 of the assembly 10 to about half or remain unfilled. On the upper surface 11, beyond the surface of the first or second region 1 or 2, preferably to a height of less than or equal to h / 2 or a little less than this, or, for example, a height h of 25 % To 40%, ie the total length of the bolts 13, 13 ′ is preferably 55% to 100%, in particular 70% to 85% of the height h. The diameter of the bolts 13, 13 ′ preferably corresponds to the diameter of the holes 14, 14 ′, especially if the assembly member 10 is manufactured in one piece, or slightly more (especially for application). Smaller or slightly larger (especially to push in). Preferably the diameter of the bolts 13, 13 'is about 0.5 mm to 1 mm, or about 2% to 7% smaller than the diameter of the holes 14, 14', so that the bolts 13, 13 'can be used without difficulty. Engages in the holes 14, 14 'and can move slightly in it.
