Description

Anyone including a child, an elderly person, or a person who performs rehabilitation by using a plurality of block pieces and fitting or detaching the convex part of the block piece to or from a concave part of another block piece The present invention relates to an assembly block for play that can be enjoyed and assembled.

  The assembly block for play is formed in a structure that allows a plurality of block pieces to be fitted and removed, and generally, the projections of the block pieces are fitted into the depressions of the other block pieces to obtain the desired shape as a whole. It is used by the method of combining so that it may become, or combining the block pieces of the same color or different colors.

Therefore, the mounting position and dimensions of one or more protrusions in one block piece and the installation position and dimensions of one or more recesses are precisely constructed so that the block pieces can be fitted together. In general, a block piece made of a solid plastic by a manufacturing method using a mold such as injection molding is employed. Recently, a method of forming a member constituting a block piece with a foam of a synthetic resin having high elasticity has been used with emphasis on safety and the like.
Japanese Patent Laid-Open No. 06-190154

  However, in the case of a block piece made of a synthetic resin foam with an emphasis on safety etc. The convex member is immersed in the concave portion of the base material on the lower end surface, and the life of the block piece itself is relatively short.

  Furthermore, the block piece made of solid plastic has a hard surface and a low elasticity, so that the touch is bad. Moreover, even if it is a synthetic resin foam, a skin layer (a dense and hard coating layer on the surface of the foamed synthetic resin formed by melting and cooling by heating) can be performed by heat-treating the base material and the convex member. It is generated, or bubbles on the surface of the member are crushed and hardened by the pressure at the time of punching with the blade, and the touch is not good.

  The present invention has been made in order to solve the above-described problems. Even a block piece made of a synthetic resin foam is durable, has a good touch, and is suitable for children, the elderly, or rehabilitation. It provides an assembly block for play that anyone can enjoy and assemble.

  A first means of the present invention is an assembly block for play made of a foam material of a closed cell synthetic resin, and a block provided with a stop member and a fitting member for supporting a convex member on the upper surface of the base material It is in the configuration of pieces.

  The second means of the present invention is an assembly block for play made of a foam material of a closed cell synthetic resin, and at least after the base material, the stopper member, and the fitting member are fixed to each other, the base material In addition, there is a block piece manufacturing method in which side surfaces of the stopper member and the fitting member are cut so that the side surfaces are the same surface.

  An assembly block for play made of a foam material of closed-cell synthetic resin, comprising a stopper member and a fitting member for supporting the convex member on the upper surface of the base material. It is possible to obtain a block piece in which the member does not immerse in the concave portion of the base material on the lower end surface and has a high breaking strength in the horizontal direction, and can be used repeatedly over a long period of time.

  An assembly block for play made of a foam material of closed cell synthetic resin, wherein at least a side surface of each member is formed in a step of forming a side surface of the block piece applied after joining the base material, the stopper member and the fitting member. Since the manufacturing method is to make the same surface by cutting the surface, there is no step between the side surfaces of the respective members, and the cutting process prevents bubbles on the surface from collapsing, and it is touched by hand when using the assembly block for play. There is no sense of incongruity, and it can be finished into a block piece that is rich in elasticity and easy to touch.

Embodiments of the present invention will be described below with reference to FIGS. In each figure, the same code | symbol shall represent the same or the same kind of member, and added a to the end of the code | symbol in the member in the middle of a process.

One example of this embodiment is shown in FIG. 1, but in this figure, a block piece in the case where there are two pairs of convex portions and concave portions will be described as an example. The block piece 7 is composed of a base material 1, an impact member 2, a fitting member 3, and a convex member 4, all of which are made of a closed cell synthetic resin foam. The base material 1 has a through hole composed of two cylindrical spaces penetrating in a direction perpendicular to the upper surface. Further, the lower surface of the stopper member 2 having no through-hole is fixed to the entire upper surface thereof, and the upper surface of the stopper member 2 is fitted with a through-hole formed of two cylindrical spaces penetrating therethrough. The lower surface of the member 3 is fixed over the entire surface. The two convex members 4 and 4 are fixed in contact with the upper surface of the stopper member 2 through the through holes of the fitting member 3.

  In addition, the structure provided with the stopper member 2 is the pressing force applied to the upper surface of the convex member that is generated when the convex part of the block piece is inserted into the concave part of another block piece or when the block piece is stepped on, for example. This is to prevent the convex member from entering the through hole of the base material. Furthermore, the reason why the fitting member 3 is provided is to support the side surface of the portion where the convex member is inserted and to increase the breaking strength in the horizontal direction.

In addition, the synthetic resin foam is used as a material because it is highly elastic and safer even if used by children, elderly people, rehabilitation persons, etc. This is because the protrusions of the block piece and the recesses of the other block pieces can be easily fitted and removed by the elasticity. Furthermore, since the foam is made of closed cells, there is no water absorption, and it can float and play in water, and dirt does not penetrate into the block piece and can be easily washed with water.

2 shows the positional relationship between the through hole of the base material 1, the through hole of the fitting member 3, and the substantially cylindrical convex member 4. The inner diameter r1 of the through hole of the base material 1 and the fitting member 3 are shown in FIG. The inner diameter r2 of the through hole and the outer diameter r3 of the substantially cylindrical column of the convex member 4 have substantially the same dimensions, and each of the through hole of the base material 1, the fitting member 3 and the convex member 4 that are opposed to each other with the stopper member 2 interposed therebetween. Are centered on a common x-axis. Further, the protruding amount 11 of the convex member 4 from the upper surface of the fitting member 3 is the same as or smaller than the depth 12 of the base member 1.

  Here, the reason why the inner diameter r2 of the through hole of the fitting member and the outer diameter r3 of the substantially cylindrical column of the convex member are set to be substantially the same size is that the diameter of the convex member 4 and the fitting member 3 are matched and supported. In order to increase the breaking strength in the horizontal direction, the inner diameter r1 of the through hole of the substrate 1 and the outer diameter r3 of the substantially cylindrical column of the convex member are set to have substantially the same size. This is to prevent the convex portion from being easily dropped from the concave portion due to its own weight or the like. Moreover, the through-hole of the base material 1, the through-hole of the fitting member 3, and the central axis of the convex member are formed on a common x-axis so that the shape is adjusted when the block pieces are assembled. It is to do. Furthermore, the protrusion amount l1 is set to be equal to or smaller than the depth l2, and when the block pieces are assembled, the upper surface of the fitting member 3 and the lower surface of the base material 1 of the other block piece come into contact with each other stably. This is because the shape of the block pieces is adjusted while being supported. In addition, the periphery of the upper surface of the convex member 4 is good also as a structure chamfered so that it may be easy to insert in the through-hole of the base material 1 of another block piece.

  Next, the manufacturing method of the block piece in this invention is demonstrated. For example, heat is applied from a raw material made of a foamed material such as polyethylene resin, polypropylene resin, ethylene vinyl acetate copolymer (EVA) resin to a foamed material that becomes a base material, a stopper member, a fitting member, or a convex member with a blade or the like. Cut out in no way. The horizontal dimensions of the base material 1a, the stopper member 2a, and the fitting member 3a cut out at this time are slightly larger than the horizontal dimensions of the base material 1, the stopper member 2, and the fitting member 3 that finally become block pieces. Keep it. Further, a through hole having a radius r1 is passed through the base 1a and a through hole having a radius r2 is passed through the fitting member 3a with a cylindrical blade or the like. In addition, it is good also as a manufacturing method which performs the said cutting-out process and the process of forming the said through-hole simultaneously.

  Next, the upper surface of the stopper member 2a and the lower surface of the fitting member 3a are bonded with, for example, an adhesive that does not generate harmful substances so that the side surfaces of the respective members are substantially aligned with each other. The upper member 5 is formed by bonding the lower surface of the convex member 4 to the upper surface of the stopper member 2 with the adhesive or the like.

  By the way, the joining method of the base material 1 and the upper member 5a will be described. As shown in FIG. 3, the lower surface of the stopper member 2a of the upper member 5a inserted into the upper mold A having a hole capable of positioning and holding the convex portion and the through hole of the base material can be positioned and held. The upper surface of the substrate 1a attached to the lower mold B having a columnar convex portion is bonded with the adhesive. At this time, the central axis of the hole of the upper mold A and the central axis of the corresponding convex part of the lower mold B are set in advance so as to be on the common y axis, and the upper mold A is guided by guide means (not shown). And the lower die B are brought close to each other to bond the lower surface of the stopper member 2a and the upper surface of the base material 1a. Therefore, the central axis of the through hole of the base material 1a coincides with the central axis of the substantially cylindrical shape of the convex member 4.

  On the other hand, the side surface of the block piece 7a in which the upper member 5a and the base material 1a are bonded is fixed to a jig or the like (not shown) and is fitted to the side surface of the base material 1a and the side surface of the stopper member 2a as shown in FIG. The side surface of the member 3a is cut with one blade so as to be the same surface. In this embodiment, as shown in the figure, a side surface of the block piece 7 as a finished product is formed using a cutting machine having a cylindrical rotary cutting blade. In addition, as this cutting machine, you may use the sliding cutting machine provided with the rotary cutting blade which slides on the type | mold of the same shape as the side surface of the block piece 7, for example.

  Here, the side surface of the block piece 7a is formed by cutting with a single blade so that the steps of the side surfaces of the base member 1, the stopper member 2 and the fitting member 3 are eliminated, and the side surfaces of the respective members are the same. For example, other known cutting methods such as a saw blade may be used as long as the side surfaces of the respective members can be made the same surface and the foam bubbles are not easily crushed. I do not care.

  By the way, the reason why the side surfaces of the base member 1, the stopper member 2 and the fitting member 3 are the same surface is to eliminate the uncomfortable feeling when touched by hand when using the assembly block for play. The reason why the cutting process is used in the formation of is that the air bubbles on the side surface of the block piece are not crushed and the elasticity is high and the touch is improved.

Depending on the purpose of use, the base material 1, the stopper member 2, the fitting member 3, and the convex member 4 in one block piece may be the same color or different colors. Similarly, a plurality of block pieces can be the same color or different colors.

  Moreover, although the block piece which has two sets of convex parts and a recessed part was demonstrated in the present Example, even if it is a block piece which has one set or three or more sets of convex parts and recessed parts, it is manufactured by the same method, and the same There is an effect.
