Description

The present invention relates to an assembly toy.

Conventionally, toys include those that involve assembling block parts or specific structures, or disassembling and reassembling them, or disassembling and storing them. In toys of this type and other block assembly items, it is important that the assembled parts can be easily and securely joined and disassembled. One example of a structure that allows for easy joining and disassembly is one in which parts fit together (for example, Patent Document 1).

The structure described in Patent Document 1, for example, in the block assembly structure of a house model, discloses a structure in which the roof, pillars, and other partition parts can be connected and disassembled by fitting mating grooves with mating protruding strips or mating protruding parts.

Japanese Utility Model Application Publication No. 61-68280

In Patent Document 1, the strength of the connection between the mating groove and the mating protrusion depends on the dimensional accuracy of the mating groove and the mating protrusion. In other words, high dimensional accuracy is necessary for concave-convex mating, since the connection strength and ease of disassembly are determined by the dimensional accuracy. In particular, when manufacturing parts from synthetic resin, the dimensions must be set and the mold manufacturing dimensions adjusted taking into account the properties and characteristics of the resin used, making dimensional adjustment extremely difficult.

Generally, in construction toys, for example, in structures where a horizontal part is connected to the surface of a wall part and other objects can be placed on the horizontal part for play, the horizontal part needs to be firmly connected and is also desired to be easily disassembled.

The objective of the present invention is to provide an assembly toy that can be securely assembled and easily disassembled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a construction toy according to one embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a partially cutaway perspective view showing the external appearance of the construction toy, FIG. 2 is a plan view showing a wall member 2, and FIG.

As shown in FIG. 1, the construction toy 1 is made of synthetic resin with a certain thickness, and includes a wall member 2 with both ends slightly bent so that it can be placed vertically, and a floor plate member 3 that is connected to the wall member 2 in a direction perpendicular to the wall member 2 and can be detached in the direction perpendicular to the wall member 2. For example, the construction toy 1 can be used as a vehicle model base where vehicle models and other models can be placed on the floor plate member 3 and played with.

The floor plate member 3 is attached to the wall member 2 in the height direction, for example, at the middle level as shown in FIG. 1, but can also be attached freely to the lower or upper end sides of the wall member 2, as described below. The free end side of the floor plate member 3 (the side opposite to the side connected to the wall member 2) is also equipped with a structure that allows a ramp or the like (not shown) to be connected. Therefore, the vehicle model on the floor plate member 3 can be played with by lowering it down using the ramp or climbing up the ramp.

As shown in Figure 2, the wall member 2 has a structure in which, for example, both ends are bent forward at an appropriate angle (hereinafter, the side where the floor plate member 3 is attached is referred to as the "front") as described above. This bent structure is convenient because it can stand on its own when standing vertically. In addition, the connecting structure for attaching the floor plate member 3 is provided at the upper and lower end portions and the center portion of the front of the wall member 2.

The connecting structure has two different configurations: a joint locking portion 10 and an uneven holding portion 20. The joint locking portion 10 is composed of a clamping portion 12 (see FIG. 2) provided on the wall member 2 and a clamped portion 11 (see FIG. 3) provided on the floor plate member 3. The uneven holding portion 20 is composed of a recess 22 (see FIG. 2) provided on the wall member 2 and a protrusion 21 (see FIG. 3) provided on the floor plate member 3.
For example, as shown in Figure 2, the wall member 2 is provided with adjacent alternating clamping portions 12 that are provided on the floor plate member 3 and can clamp the clamped portion 11, and recesses 22 that are provided on the floor plate member 3 and allow the insertion of protrusions 21.

Although the wall member 2 is shown as a single plate in the figure, it can be disassembled and reassembled at the dividing line 1c in the center of the left and right sides, and other wall members can be attached to both left and right ends.

As shown in FIG. 3, the floor plate member 3 is composed of three members, for example, a central floor plate 3a, a left floor plate 3b, and a right floor plate 3c. The aforementioned connecting structure that connects to the wall member 2 is provided on one end side of each floor plate. That is, clamped portions 11 that can be connected to the clamping portions 12 of the wall member 2 and convex portions 21 that can be inserted and engaged with the concave portions 22 of the wall member 2 are provided alternately on one end portion 3t of the floor plate member 3.

The connecting structure of the floor plate member 3 will be described below with reference to Figures 4 and 5. Note that Figure 4 is an enlarged perspective view of one end 3t of the floor plate member 3, and Figure 5 is an enlarged plan view of one end 3t of the floor plate member 3.

As shown in Figs. 4 and 5, the clamped portion 11 of the floor plate member 3 is configured to extend outward from one end 3t. More specifically, the clamped portion 11 is a plate-shaped member having a width W1 that is approximately equal to the thickness of the floor plate member 3. The clamped portion 11 has a tip portion 11e that is thicker than the thickness t1 of the protruding base portion 11b (so that the width t2 of the tip portion 11e indicated in Fig. 4 satisfies t2>t1). The protruding portion 21 provided adjacent to the clamped portion 11 is configured, for example, in a trapezoidal shape. The protruding height H2 of this protruding portion 21 is equal to or greater than the protruding height H1 of the clamped portion 11.

The following description will be given with reference to Figures 6 and 7. Note that Figure 6 is an enlarged perspective view of the main part of the wall member 2, and Figure 7 is a cross-sectional view of the main part in the thickness direction of the wall member 2.

As shown in Figures 6 and 7, the clamping portion 12 of the wall member 2 has a pair of plate-shaped elastic pieces 12p, 12p provided inside the recessed portion 5. The pair of elastic pieces 12p, 12p extend in parallel from the bottom of the recessed portion 5 toward the opening side. The pair of elastic pieces 12p, 12p have protruding tip portions 12e, 12e whose tips protrude toward the opposing sides. Therefore, the clamping portion 12 has an insertion space 12sp that is wide at the back when viewed from the opening side of the recessed portion 5. The clamped portion 11, which has a thick tip, is inserted into this insertion space 12sp, so that the clamped portion 11 is engaged with the clamping portion 12.

The protruding height H3 of the pair of elastic pieces 12p, 12p is configured to be equal to or smaller than the depth H4 of the recessed portion 5. In other words, the pair of elastic pieces 12p, 12p are arranged so that their tips do not protrude from the recessed portion 5.

As shown in FIG. 7, the pair of elastic pieces 12p, 12p are formed on either side of an opening 12h that penetrates the back side of the wall member 2. The structure in which the pair of elastic pieces 12p, 12p are formed at a position that sandwiches this opening 12h makes it possible to easily form the protruding tip 12e without forcibly removing the mold after resin injection when the elastic piece 12p is injection molded in a molding die by utilizing the structure of this opening 12h. This makes it possible to greatly protrude the protruding tip 12e of the elastic piece 12p without complicating the molding die.

The recess 22 of the wall member 2 is formed in a trapezoidal recess shape adjacent to the clamping portion 12, into which the protrusion 21 of the floor plate member 3 is inserted and engaged.

The following description will be given with reference to Figures 8 and 9. Figure 8 is a schematic explanatory diagram showing the joining operation of the wall member 2 and the floor plate member 3, and Figure 9 is a schematic cross-sectional view showing the joined state of the wall member 2 and the floor plate member 3.

In the connecting structure configured as described above, for example, as shown in FIG. 8, the clamped portion 11 of the floor plate member 3 is operated so as to be pushed into the clamping portion 12 of the wall member 2.
At this time, the left and right positioning is determined visually, but the positional relationship between the convex portion 21 and the concave portion 22 serves as a rough guide, and in the initial stage of the pushing operation, the inclined surface 21s of the convex portion 21 and the inclined surface 22s of the concave portion 22 have a guide function in the left and right direction due to their contact.

When both components are pushed in, the tip 11e of the clamped portion 11 enters the insertion space 12sp, pushing apart the space between the protruding tips 12e, 12e of the elastic pieces 12p, 12p. The locked state of the coupling locking portion 10 is maintained by the hooking of the protruding tips 12e of the pair of elastic pieces 12p, 12p with the tip 11e of the clamped portion 11, as shown in FIG. 9. This hooking state is achieved with a width W2 in the thickness direction of the floor plate member 3. More specifically, the hooking state of the clamped portion 11 and the clamping portion 12 is a line contact with a width approximately the thickness of the floor plate member 3, in other words, a line contact with a length in a direction perpendicular to the removal direction. This allows the coupling locking portion 10 to perform reliable locking.

Furthermore, the multiple convex portions 21 of the floorboard member 3 are fitted into and engaged with the concave portions 22. As a result, even if an external force F in the thickness direction of the floorboard member 3 acts on the floor surface 3s of the floorboard member 3, the wall surfaces of the concave and convex engagements can come into contact with each other, and even if a large external force F is applied, the floorboard member 3 can sufficiently withstand the application of the large external force F and maintain its connection angle.
In addition, the wall member 2 is provided with, for example, a trapezoidal auxiliary rib 2b (see Figure 9) in a position close to the front and back surfaces of the floor plate member 3, making it possible to provide auxiliary support for the floor plate member 3.
In this way, the wall member 2 and the floor plate member 3 are securely engaged by being clamped by the connecting and engaging portions 10, and are reinforced by the concave-convex engagement of the concave-convex retaining portions 20, so that they are detachably joined together.

The wall member 2 and floor plate member 3 of this embodiment are not particularly limited as long as they are made of synthetic resin, but can be made of, for example, methyl methacrylate acrylonitrile butadiene styrene (MABS) or polycarbonate (PC).

A modification of the above embodiment will be described with reference to FIGS.
FIG. 10 is a perspective view showing a clamped portion 11 in the modified example, and FIG. 11 is a schematic cross-sectional view showing the joined state of a wall member 2 and a floor plate member 3 in the modified example shown in FIG.

As shown in Figure 10, the clamped portion 11 of the floorboard member 3 in this modified example has the same configuration as that shown in Figure 4 with respect to the protruding base 11b and the tip 11e, but a roughly semicircular reinforcing piece 11u that is flush with the floor surface 3s of the floorboard member 3 is provided on one end side (the upper side in the figure) of the protruding base 11b and the tip 11e. In other words, the strength of the clamped portion 11 is increased by providing the reinforcing piece 11u perpendicular to the protruding base 11b and the tip 11e.

When the clamped portion 11 configured in this manner is engaged with the clamping portion 12, as shown in FIG. 11, the protruding tip 12e of the pair of elastic pieces 12p, 12p is hooked with the tip 11e of the clamped portion 11, as in the case shown in FIG. 9, but in addition to this, the upper end surface 11us of the reinforcing piece portion 11u faces the inner surface 5w of the recessed portion 5. Therefore, when an external force F is applied to the floor surface 3s of the floor board member 3, for example, in the thickness direction of the floor board member 3, the upper end surface 11us can come into contact with the inner surface 5w. This makes it possible to more reliably maintain the engaged state.

As described above, according to the assembly toy 1 of this embodiment, the wall member 2 and the floor plate member 3 are joined by the clamping of the joining locking portion 10 and the uneven engagement of the uneven holding portion 20, so that the joining locking portion 10 can maintain the locked state of both members, and because the locking portion of the joining locking portion 10 has a width in the thickness direction of the floor plate member 3, the engagement width of the locking portion can be increased. As a result, this contributes to increasing the engagement force. Furthermore, the uneven wall surfaces can come into contact with each other due to the uneven engagement of the uneven holding portion 20, and for example, when another toy or the like is placed on the floor plate member 3, the strength to maintain the intersection angle of the floor plate member 3 with respect to the wall member 2 is improved.

In this way, in conventional connection structures that rely on the bonding strength of the recessed and protruding parts, the molding precision of the recessed and protruding parts must be high in order to achieve high bonding strength. However, in this embodiment, the retention of the two joined components is achieved by the elastic joint retaining part 10, so that the bonding strength can be ensured without increasing the molding precision of the recessed and protruding parts.

In addition, in the assembly toy 1 of this embodiment, the connecting locking parts 10 and the uneven holding parts 20 are provided alternately adjacent to each other, so that the locking force in the direction in which the wall member 2 and the floor plate member 3 come out (thickness direction of the wall member) and the force maintaining the connection angle (intersection angle of both members) between the wall member 2 and the floor plate member 3 can be made uniform over the entire connecting part. In addition, the uneven positional relationship of the uneven holding parts 20 serves as a marker for the installation position during assembly, improving ease of assembly.

In addition, in the construction toy 1 of this embodiment, the clamping portion 12 has a pair of plate-like elastic pieces 12p, 12p that face each other to form a wide insertion space 12sp, and the clamped portion 11 is composed of a plate-like member that can be inserted and engaged into the insertion space 12sp, so that the engagement between the clamped portion 11 and the clamping portion 12 is elastically engaged with a predetermined width in a direction perpendicular to the direction of the force in the removal direction. As a result, the locking function of the connecting locking portion 10 can be improved.

In addition, in the assembly toy 1 of this embodiment, the pair of elastic pieces 12p, 12p are provided within the recessed portion 5, and the tips of the elastic pieces 12p, 12p are arranged so as not to protrude from the recessed portion 5, so that the elastic pieces 12p, 12p are protected and are less likely to be damaged or broken.

In addition, in the assembly toy 1 of this embodiment, the pair of elastic pieces 12p, 12p are formed on either side of the opening 12h, so the amount of protrusion of the protruding tip 12e at the tip of the elastic piece 12p can be increased without complicating the mold structure. As a result, the amount of hooking of the elastic piece 12p with the clamped part 11 can be increased, making it easy to increase the locking force.

In addition, in the construction toy 1 of this embodiment, the clamped portion 11 is formed on the same side as the convex portion 21, and is formed to be equal to or lower than the protruding height H2 of the convex portion 21. This makes the clamped portion 11 less susceptible to damage or breakage.

In addition, in the assembly toy 1 of this embodiment, the combined shape of the convex portion 21 and the concave portion 22 of the concave-convex holding portion 20 is formed into a trapezoid, so that when assembling the wall member 2 and the floor plate member 3, visibility is good and it is easy to identify the combination position for installation. In addition, the trapezoidal inclined surfaces 21s, 22s of the convex portion 21 and the concave portion 22 can function as a guide for alignment during the connecting operation, improving the ease of assembly.

Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the structure of the connecting locking portion 10 is configured such that the clamping portion 12 is provided on the wall member 2 and the clamped portion 11 is provided on the floor plate member 3, but it may be configured conversely such that the clamped portion 11 is provided on the wall member 2 and the clamping portion 12 is provided on the floor plate member 3.

In addition, in the above embodiment, the structure of the uneven holding portion 20 is configured such that the wall member 2 has a recess 22 and the floor plate member 3 has a protrusion 21, but the opposite configuration may be used, in which the wall member 2 has a protrusion 21 and the floor plate member 3 has a recess 22.

In the above embodiment, the wall member 2 is provided with a trapezoidal auxiliary rib 2b as a rib structure facing the front and back surfaces of the floor plate member 3, but this is not limited thereto. For example, the contact portion of the wall member 2 facing the upper and lower edges of one end 3t of the floor plate member 3 may be a step structure. Also, a pattern or uneven structure of the wall member 2 may be used to form a rib structure facing the front and back surfaces of the floor plate member 3.

In addition, in the above embodiment, the clamping portion 12 is formed in the recessed portion 5 of the wall member 2, but if the clamping portion 12 is provided on the floor plate member 3 side, this recessed portion may be configured such that the recessed portion 5 is formed on one end portion 3t, or the clamping portion 12 may be configured to be provided between the protruding portions 21.
