Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a rocking toy device having a seat configured using a child's joint.

[Conventional technology]

In particular, since safety must be fully considered in rocking play equipment intended for young children, it is necessary to assemble a rising side plate with a backrest for the seat of the play equipment. In this case, conventionally, a simple gazette plate is applied to the corner portion of the seat plate and the side plate and bolted to connect them. For example, a joint for an assembly shelf according to Utility Model Application Publication No. 58-52307 and a connection fitting for an assembly type enclosure according to Utility Model Application Publication No. 58-120305 disclose a joint for connecting plate pieces in a dogleg shape. There is. However, all of these joints are integrally molded at right angles and are bolted only on one side, so that the bolts do not penetrate the plate pieces, so the adhesion between the plate piece and the joint is weak, and costs are inevitably increased. be done. Furthermore, since it is a fixed molding, it is necessary to specially mold the joint when the plate pieces to be connected have different wall thicknesses, which results in poor versatility. Further, in the tilling claw attachment device for a power tiller according to Utility Model Publication No. 48-36885, a configuration is disclosed in which the tilling claw is provided with a hexagonal hole and a square shaft of a bolt is fitted into the tilling claw to fix the screw. However, if the nut is not tightened weakly, the tiller claw may become loose and the screw may come off, so it cannot be used as is for the joint of a rocking toy.

[Problem that the invention attempts to solve]

This invention was made to solve the above problems, and the main problem is that it is possible to form a seat by simply and reliably connecting the connected members at a predetermined angle, regardless of the wall thickness. We are here to provide you with the best rocking toy equipment possible.

[Means to solve the problem]

In order to achieve the above-mentioned problem, this invention provides a rocking play equipment in which a seat is formed by connecting a plate-shaped connected member to a swingably supported seat support via a joint, the joint comprising: (a) The bottom part is formed into a mountain-shaped curved surface bent at a predetermined angle, and has a pair of side walls extending from the bottom part parallel to each other and spaced apart from each other on both sides, one of which is located at an opposing position of the pair of side walls. A joint part is provided with a pair of bolt holes consisting of square holes, and (b) another joint part whose bottom is formed in the shape of a mountain at the same angle as this joint part is formed integrally with one sloped surface of the mountain shape. (c) fitting and aligning the ends of the plate-shaped connected members into each of the joint parts, and forming a square base part corresponding to the square hole in the middle part; A seat having a desired shape is formed by tightening bolts and connecting the connected members at a predetermined angle. We are taking technical measures.

[Effect]

The joint consists of two joint parts, and the joint parts can be selected according to the wall thickness of the members to be connected. An obtuse-angled, bifurcated joint can be formed by simply overlapping and fixing one of the inclined surfaces of the bottom of the selected joint. Using this joint, the members to be connected are fitted into the respective joint portions of the joint, and each is tightened with a bolt to form a seat of the rocking toy at a predetermined angle. At this time, the bolt engages its square part with the square hole of the joint part to restrain its rotation, and the connected members are tightly clamped between the both side walls of the joint part, and the seat is completed. Therefore, even if the seat support swings, it is safe because the joints reliably connect the members to be connected.

【Example】

Below, preferred embodiments of this invention will be described based on the drawings. The swinging play equipment illustrated in FIG. 1 includes a base 1 for stabilizing installation on an installation surface, and a chain 2 and a rubber-like elastic body 3 on the base as shown in FIG. The seat support 4 includes a seat support 4 held on the seat support 4, and a seat 5 held on the support. A handlebar 6 that stands up in front of the seat 5 is integrally fixed to the seat support 4. A footrest 7 is integrally provided at the lower end of the handlebar 6. On the other hand, the seat 5 has narrow projecting pieces 5 at both ends.
It is assembled by a seat plate 50 in which 0A and 50B are integrally formed, side plates 51 and 52 rising from both ends in an inverted V-shape, and a backrest plate 53 spanning between the rear portions of the side plates. More specifically, the seat support 4 and the side panels 5
Reference numerals 1 and 52 serve as members to be connected to each other, and engagement holes 51A and 52A are provided at opposing positions on the lower side of both side plates 51 and 52, into which the protruding pieces 50A and 50B of the seat plate 50 are fitted and supported. It has been established. The protruding pieces 50 of the seat plate 50 are inserted into the engagement holes 51A, 52A of the side plates 51, 52.
A, 50B are fitted into the seat support 4 and integrally connected to the seat support 4 via the joint 8. As shown in more detail in FIG. 5, this joint 8 consists of two joint parts 80 and 81, each of which has the same channel shape and extends at a predetermined connection angle. The bottoms of these joints 80 and 81 are mountain-shaped inclined surfaces 80a and 80b and 81a and 81b bent at a predetermined angle (obtuse angle).
It is formed as. The joint portions 80 and 81 are configured such that one of the inclined surfaces 80a and 81a are integrally connected to each other by means such as welding. Both joint parts 80 and 81 are integrally connected to each other at an obtuse angle. The inclined surfaces 80a, 80 are provided at the joint portion.
A pair of side wall portions 80s, 8 extend upward from the edges of b and 81a, 81b and are spaced parallel to each other on both sides.
0s and 81s, 81s are provided, and bolt holes 80c, 81s are provided at opposing positions of the pair of side walls.
0d, 81c, and 81d are provided. Among these bolt holes, one of the bolt holes 80c and 81c facing each other is a round hole, and the other bolt hole 80d and 81d is a square hole. In this way, one of the joint parts 80 is externally fitted and aligned with both ends of the upper plate part of the seat support body 4, and is tightened with the bolts 9 and nuts 10. Then, inside the other joint part 81, the side plate 51,
The lower end of 52 is fitted and aligned, and the bolt 1
1 and a nut 12. In this case, each bolt 9, 11 has a rectangular base portion 9A, 11A (only one of which is shown in FIG. 5) integrally connected to the head of each bolt. These corner portions 9A and 11A are connected to the joint portion 8.
It is fitted into and aligned with the square bolt holes 80d and 81d of No. 0 and 81. Therefore, the bolts 9 and 11 do not rotate together when the nuts 10 and 12 are tightened, and the bolts can be prevented from loosening or falling off after tightening. Note that during the above tightening, both side plates 51 and 52
It goes without saying that the protruding pieces 50A, 50B of the seat plate 50 are fitted and supported in the respective engagement holes 51A, 52A as described above. In addition, a backrest plate 53 that straddles between the two side plates 51 and 52 at the rear thereof is connected to the angle joint 1.
3 and is fastened by bolt tightening means.

[Effect of the idea]

As described above, according to this invention, since the bottom of the joint is formed in the shape of a mountain with the same angle, the joint is formed by combining the joint parts with a width that matches the plate thickness of the members to be connected, and is used to form the joint. Since the connecting members are connected,
Even when connecting members having various plate thicknesses, the joints can be used without preparing separate joints. In addition, the connected members are tightened to the joint by bolts, and the square base of the bolt is restrained in the square hole of the joint and does not rotate, so even if the connected members swing, the bolt will rotate. The tightened state can be maintained reliably without any problems.
