Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for connecting end blocks in a block toy.

As a type of block toy, blocks that serve as units are sequentially connected in a straight line using connectors such as hinges, and changing patterns are obtained according to the relative movement between adjacent blocks that are connected to each other. There are things to play with.

To make this kind of block toy even more interesting,
It is important to increase the number of patterns of change by increasing the degree of freedom of the connections. This is particularly important for connecting an end block located at an end, such as the beginning or end, with an adjacent block. I mean,
This is because the end block needs to respond to all changes in the subsequent intermediate block.

An object of the present invention is to increase the degree of freedom in connecting an end block and an adjacent block.

Other objects of the invention will become apparent from the following description and the accompanying drawings.

In this invention, the degree of freedom of the connection is increased as a whole by the following three features.

In other words, the end block can be rotated around the support shaft by a support shaft that stands upright on one side of the end block, and the end block and the adjacent block are connected by a hinge. It is made swingable, and also because of the swinging action of the hinge and the rotating action of the intermediate plate that has a specific relationship with the support shaft.
One side of an end block can be aligned with different sides of adjacent blocks.

Further, in the present invention, the end blocks are moved stepwise or intermittently, or a sound is generated when such movements are made, thereby making the end blocks even more interesting.

Hereinafter, the content of the present invention will be made clear by describing embodiments shown in the drawings.

As shown in FIG. 1, a block toy 1- includes an end block 2 having an inclined surface 2a on two parts and having a different shape from the others, a block 3 adjacent thereto, and one or two parts following the block 3. ”2 and other blocks 4.

The blocks 3 and 4 have an internal hollow columnar block body 53.
54, and side plates 63 and 64 rotatably attached to the end face portions thereof. Each block 3 like this,
4 is a hinge 7 fixed to the outer peripheral portion of the side plates 63 and 64;
It is possible to swing around the center O as a fulcrum. Therefore, each block 3, 4 performs a two-dimensional, three-dimensional relative movement due to the swinging action of the hinge 7, and also a three-dimensional movement due to the rotational action of the side plates 63, 64 that are integral with the hinge 7. It can also make movements.

On the other hand, the end block 2 is also swingably connected to the block 3 by a similar hinge 70.

The hinge 70 has a shaft 9 attached to an intermediate plate 8, which will be described later.
and a bearing 11 side attached to the fixed plate 10 on the block 3 side (see Figures 1 and 2). As shown in FIG. 3, the shaft 9 has a shaft portion 9 having a regular octagonal cross section.
0, while the bearing 11 supporting the shaft 9 has a surface 11-1 and a notch 112 running in the axial direction, which fits the shape of the shaft part 90. The latter bearing 1-1 is made of an elastic material such as plastic, so that the shaft 9 changes intermittently in stages around the bearing 11. Such movements are extremely effective in evoking the feeling of joints or robot-like movements.

Next, the end block 2 is rotatably provided with a support shaft 1-2. The support shaft 1-2 stands upright on the back surface 2b of the end block 24-, and its bottom side is connected to the end block 24-.
The inside and the top side are located on the outside, respectively.

The bottom end of the support shaft 1-2 has a regular octagonal cross section, and a portion 121 having a regular octagonal cross section is supported by a bearing 1.3. Regarding the support structure of that part,
Figure 4 makes this clear. As shown in FIG. 4, the bearing 13 includes a base portion 131 and two pieces 132 standing up from the base portion 131.
, 133, the inner peripheral surfaces of which are connected to the support shaft 12.
It is adapted to the shape of the side portion 121. Upper end of each two pieces 132, 133 1-320.1-3
30 is bent inward. Bent upper end 1320
．． 1330 is approximately the same height as the support shaft 12, and since there is an opening 1-4 between the upper ends 1320 and 1330 and the bearing 13 itself is made of an elastic material, the portion 1-21- of the support shaft 12 is rotatable inside the bearing 13. Moreover, in this case, the portion 121 of the support shaft 12
Since - is a regular octagon, the support shaft 1-2 rotates intermittently in stages around the circumference, and during the rotation, the upper ends 1320, 13
30 generates a clicking sound by hitting the portion 1-21- of the support shaft 12, that is, the upper end portion 1-320.1.330 functions as a hitting piece. In addition, the depression 13 in the center between the three pieces 132 and 133
4 facilitates elastic deformation of the Evas 132, 1.33. Also, the bearing 13 can be obtained as a plastic molded product like many other parts, but
Support shaft] - To smooth the rotation of 3, support shaft] -
2 or the bearing ]-3 is preferably made of a low-friction material.

Incidentally, a metal support pin 15 is provided on the top side of the support shaft 12 so as to be orthogonal to the support shaft 1-2, and the intermediate plate 8 is supported on the support pin 1-5. ing. As shown in FIG. 2, the intermediate plate 8 is provided with a notch 80 that is open in the radial direction, and is configured to be rotatable around the support pins 1-5.

Here, the support pin 15 is set parallel to the axis of the hinge 70. Thereby, the intermediate plate 8, despite the presence of the end blocks 2.

270° (end surface 31 of block 3
- from the position to the position of the end face 32). Accordingly, the end block 2 is in the state Y shown by the dashed line ~
It can take the state of X.

Moreover, since the end block 2 itself is rotatable around the support shaft 12, the orientation of the end block 2 around the support shaft 1-2 can be freely selected in each state. In addition, the male member 1-22 at the top tip of the support shaft] 2 is
In this state, it fits into a female member (not shown) provided on each end surface 32.3] side.

As can be seen from the above description, according to the present invention, an excellent effect can be obtained in that the degree of freedom of connection between the end block 2 and the block 3 adjacent thereto can be greatly increased.
