A plurality of convex bodies 13 are arranged at equal intervals on the surface of the substrate 11, and small cylindrical bodies (beads) 15 are attached to the convex bodies 13. Hereinafter, the weld bead toy 1 will be described in detail.
The main body 3 is a member formed by integral molding with a synthetic resin, and is formed as an outer shell body having a space with a depth of about 1 to 2 cm having a substantially rectangular opening on the upper surface. A plate-like intermediate plate 17 is detachably attached to the opening of the main body 3 so as to substantially block the opening. A predetermined storage space is formed by the inner portion of the main body 3 and the intermediate plate 17 so that articles such as the small cylindrical body 15 can be stored.

A bearing 19 is provided at one end edge of the outer body that forms the opening of the main body 3, and a lid 5 made of a transparent synthetic resin material is rotatably attached to the bearing 19. It has been.
The lid 5 has a top plate 21 having substantially the same shape as the opening of the main body 3, and a peripheral wall formed so that the edge of the outer body forming the opening of the main body 3 abuts the edge. 23 is formed around the top plate 21. As an optimal example, the lid 5 is made of a transparent material.
A locking member 25 for locking the closed lid 5 is provided on the edge of the main body 3 opposite to the edge on which the bearing 19 is provided. The locking member 25 has a hook-shaped locking portion 27 at the tip, and by engaging the locking portion 27 with a locked portion 29 provided on the lid 5, the lid 5 is opened. The operation is restricted.
A handle 31 is provided in the vicinity of the locking member 25 of the main body 3, and the welded bead toy 1 can be carried by holding the handle 31.

A holding portion 9 for holding the substrate 11 is provided on the surface of the intermediate plate 17 provided so as to substantially block the opening of the main body portion 3. The holding portion 9 is formed as a substantially rectangular ridge provided so as to substantially surround the outer shape of the substrate 11. By placing the substrate 11 in the ridge, movement in the front-rear and left-right directions is regulated (see FIG. 2).
In addition, a notch 33 is provided in a part of two opposite sides of the substantially rectangular ridge, and a substantially circular recess 35 is provided on the surface of the intermediate plate 17 at the same position as the notch 33. It has been. The concave portion 35 is formed as a portion for facilitating gripping of the substrate 11 with a fingertip in order to easily take out the substrate 11 placed in the holding portion 9.

The substrate 11 is formed by integral molding of a synthetic resin having a relatively high melting temperature, such as an ABS resin. As shown in FIG. 3, the substrate 11 has a plurality of convex bodies on the surface of a rectangular plate. 13 is provided with a plurality of projections at equal intervals in the front-rear and left-right directions. In the present embodiment, the convex body 13 is formed in a columnar or conical shape having a diameter slightly smaller than the inner diameter of the small cylindrical body 15, and has a height lower than that of the small cylindrical body 15. As an optimal example, it is formed at a height of about half the length of the small cylindrical body.
Further, four engaging portions 37 a and four engaged portions 37 b for connecting to other substrates 11 are provided on the peripheral edge portion of the substrate 11. The substrate 11 can be connected by engaging the engaging portion 37a and the engaged portion 37b, and the small cylindrical body 15 can be arranged by increasing the surface area of the portion where the convex body 13 is provided. The area of the part to be can be increased (see FIG. 4).

The small cylinder 15 is a cylindrical body formed of a synthetic resin having a melting temperature lower than that of the substrate 11 such as polyethylene. The inner diameter of the small cylindrical body 15 is formed to be substantially the same as or slightly larger than the diameter of the convex body 13. Specifically, the small cylindrical body 15 has a diameter of approximately 3.5 mm and an inner diameter of approximately 1.5 mm, and the convex body has a diameter of approximately 1.3 mm at the root maximum diameter portion. Yes.
The convex bodies 13 on the substrate 11 are arranged at intervals such that when the small cylinders 15 are mounted on the convex bodies 13, the adjacent small cylinders 15 are arranged so close that they do not interfere with each other. Yes. Specifically, it arranges so that the space | interval of the adjacent convex bodies 13 may be set to about 3.5-4.5 mm. By setting such an interval, when the upper surface portion is melted and pressed, the small cylinders expand toward the periphery so that adjacent small cylinders can be welded together.
Further, as will be described below, the distance from the upper surface of the substrate 11 to the back surface of the lid 5 is formed to be slightly longer than the entire length of the small cylinder 15, and the small cylinder mounted on the substrate 11. The upper end of the body 15 is regulated by the back surface of the lid body 5 to prevent it from coming out of the convex body 13.

The relationship between the substrate 11 and the lid 5 will be described. When the small cylinder 15 is placed on the substrate 11 and the lid 5 is closed, the lid 5 is located between the back surface of the lid 5 and the upper end surface of the small cylinder 15 as shown in the sectional view of FIG. A slight gap is formed on the surface. Even if the welding bead toy 1 is handled violently with the small cylindrical body 15 mounted, the gap has a dimensional relationship such that the small cylindrical body 15 does not fall out of the substrate 11 unless the lid 5 is opened. Is formed.
Specifically, the total length of the small cylindrical body 15 is approximately 6 mm, and the distance between the substrate 11 and the back surface of the lid 5 is approximately 6.2 to 6.5 mm. Further, the height of the convex body 13 is formed to be approximately 2 to 3 mm from the upper surface of the substrate 11. Therefore, the distance between the back surface of the closed lid 5 and the upper end surface of the small cylindrical body 15 is about 0.2 to 0.5 mm, and the height of the convex body 13 is about 2 to 3 mm. Even if the body 15 moves up and down due to vibration or the like (limited to a range of about 0.2 to 0.5 mm), it does not fall out of the convex body 13.
As can be seen from the above, in order to prevent the small cylinder 15 mounted on the substrate 11 from falling off the substrate 11, the minimum condition is that the back surface of the lid 5 and the small cylinder 15 It is necessary that the distance from the end face is set smaller than the height of the convex body 13.
Further, since it is necessary to melt the upper portion of the small cylindrical body 15 by contacting an iron or the like, the height of the convex body 13 is lower than the height of the small cylindrical body 15 in anticipation of the melting portion of the small cylindrical body 15. Is set. In the present embodiment, when the diameter of the small cylindrical body, the ridges 13 and the like have the above dimensions, as an optimal example, the height of the convex body 13 is approximately half of the total length (approximately 6 mm) of the small cylindrical body 15. It is set so that it may become the size (approximately 3 mm).

Next, the usage method etc. of the welding bead toy 1 demonstrated above are demonstrated. The user can form a predetermined picture or pattern by arranging a plurality of small cylindrical bodies 15 so as to be inserted into the convex bodies 13 with the substrate 11 mounted on the main body 3.
When the creation of a picture or pattern is incomplete, if the lid 5 is closed, the back surface of the lid 5 prevents the small cylinder 15 from falling off the substrate 11 and breaks the picture or pattern being created. It is now possible to save the state being created.
Further, since the lid 5 and the main body 3 are locked by the locking member 25 constituted by the locking portion 27 and the locked portion 29, the lid 5 is inadvertently opened and a picture being created. And it will not break the pattern.

  The picture or pattern created by the small cylinder 15 on the substrate 11 can be integrated by melting the small cylinder 15 with heat, welding them together, and connecting them. The welding is performed by placing a paper coated with paraffin, silicon, or the like on the small cylinder 15 and pressing an iron set at a low temperature from above to melt the upper portion of the small cylinder 15.

Next, a second embodiment according to the present invention will be described.
The embodiment is characterized in that it is constituted by a substrate and a lid that can cover the substrate as minimum components.
As in the above-described embodiment, the substrate is a plate-like member in which a plurality of convex bodies are arranged on the surface at equal intervals, and small cylindrical bodies (beads) are attached to the convex bodies. It is configured.
The lid is configured as a member to be attached to the substrate, and has a top plate that covers at least the top of the convex body formed on the substrate, and the upper end surface of the small cylinder attached by the back surface of the top plate Is regulated to prevent falling out. The distance between the back surface of the top plate of the lid and the top surface of the substrate is configured to be slightly longer than the entire length of the small cylindrical body as in the above-described embodiment. In addition, the dimensional values and the like of the substrate, the small cylindrical body, and the top plate (lid body) are applied to the present embodiment in the same manner as described in the above-described embodiment.

As an example, the case where the substrate is a square plate having a predetermined area will be further described. On the upper surface of the substrate, a plurality of conical convex bodies having a root portion with a diameter of about 1.3 mm and a height of about 3 mm are arranged in a matrix at intervals of about 4 mm. Further, an engaged portion for mounting the lid is provided on the side edge of the substrate. The engaged portion is formed as a concave portion that engages with an engaging portion (projection) of the lid described below.
The lid has a top plate that substantially covers at least the upper surface of the substrate, and is provided with an engaging portion that engages with the engaged portion of the substrate. The engaging portion is a protrusion formed near the end portion of the side wall having a predetermined width depending on the peripheral edge of the top plate, and the lid body is detachably fitted to the concave portion provided on the side edge of the substrate. It can be detachably attached to the substrate.
The lid attached to the substrate is fixedly held at a predetermined position with respect to the substrate by the side wall around the top plate. As an optimal example, as described above, the distance between the back surface of the top plate and the top surface of the substrate is set to be slightly longer (6.2 to 6.5 mm) than the total length (6 mm) of the small cylindrical body to be mounted. .

The method for engaging the substrate with the lid is not limited to the above example, and other methods may be used. For example, a bearing portion may be provided at one end of the substrate, and the lid body may be rotatably attached to the bearing portion.
In addition, a long groove is formed on the side edges of the two opposite sides of the substrate, the protrusion on the side wall of the lid is engaged with the long groove so as to slide, and the lid is mounted from the lateral direction of the substrate. Also good. In addition, the engagement method is not limited to one example as long as the distance between the substrate and the top plate can be maintained at a predetermined dimension value.

Further, as a third embodiment, a structure in which a plurality of substrates having the same configuration as that of both the above-described embodiments in the main part are stacked in a state where a small cylindrical body is mounted can be employed. For example, when a side wall having a predetermined height (for example, slightly longer than the entire length of the small cylindrical body) is provided on the side edge of the outer shape of the substrate and another substrate of the same shape is stacked on the side wall, It is possible to provide fitting portions that are fitted to each other in the direction, and to be detachably fitted and fixed in the fitting portion in a state where a plurality of substrates are overlapped.
By adopting such a structure, there is an effect that a plurality of pictures / patterns formed by the cylindrical body can be held. For the uppermost substrate, the substrate with the lid described in the second embodiment is used to prevent the small cylindrical body from falling off by the lid, and the second and subsequent substrates are stacked. The back side of the substrate has the same action as the top plate to prevent the small cylinder from falling off, while holding the multiple pictures and patterns while preventing the small cylindrical body from dropping off at the top and middle stages. Can be done.
