Description

The invention relates to the field of equipment for children's playgrounds, in particular to rocking-balancers.

Known design according to the patent for utility model No. 43777, application No. 2004128595/20, 09/29/2004.

The rocking chair-balancer contains a support frame, a seat frame made of glued board and plywood composition, the seat is made with a back and a hand holder.

Shockproof elements in the form of rings of multilayer rubber are introduced into the design, and the seat frame itself is connected to the swing axis, which is installed in the support frame through rolling bearings.

The product is mass-produced by ZAO KSIL under No. 4102 - rocking chair-balancer ( see www.ksil.ru - product catalog).

The undoubted advantage is the simplicity of the design, the presence of rolling bearings on the axis and the introduction of shockproof elements to the design.

A disadvantage of the known design is the presence of numerous bolted joints at the steel-wood contacts, especially in the center of the seat frame.

Due to the elastic deformation, the crushing of wooden surfaces occurs and the bolted joints become loose.

Shockproof elements in the form of rings of multilayer rubber are not effective and not durable.

The process of compressing the rings to contact with the opposite inner walls practically does not create damping resistance, and with direct contact of thin walls with full compression of the rings, a clearly pronounced impact of the seat on the surface of the platform occurs.

In addition, the complete cyclic compression of the rings creates destructive kinks on the sides of the rings, especially in winter (cold!) Time and the rings break in the places of kinks and any meaning in their presence is lost.

Rockers IO-1.405.01 are even more doubtful from the point of view of safety; ИО-1.4.05.00 manufactured by ROMANA (see www.romana.ru "catalog of outdoor equipment in 2014).

These rocking chairs are equipped with hard metal brackets under the seat, limiting the contact of the seat with the floor covering.

But, as practice shows, such staples gradually penetrate even the asphalt surface, and in the case of a sandy surface of the site, they simply pierce the sand.

But the main drawback is that they have insufficient gaming appeal and functionality.

The fact is that comfortable use of the swing is possible only when the masses of the children sitting on the seats are the same, and it is almost impossible to achieve such a coincidence.

It is difficult to provide assistance from the outside:

- For an adult with sufficient effort, standing bent over a rocking chair located at a height of 0.4 - 0.6 m is extremely inconvenient, especially bending all the way to the ground.

- For the child, the efforts developed by him are not enough and also inconvenient.

The aim of the development is to create a rocking-balancer design, which would provide for effective and reliable damping of shock loads with high comfortable conditions and gaming attractiveness.

The specified goal is achieved as follows.

Structurally, the rocking chair is designed so that the third child or an adult sitting on the side of the rocking chair helps to swing, while the third child does not need to exert force, but only use its own weight to compensate for the difference in masses of the children sitting on the rocking chair, and for active their rocking.

At the same time, the shockproof element provides effective shock damping and eliminates damage to the surface of the site.

The implementation of this goal is ensured by the designs disclosed hereinafter in the description and on the presented drawings, which are the subject of the claims.

In FIG. 1, a side view schematically shows an embodiment of a rocker with a low frame.

In FIG. 2, a side view schematically shows an embodiment of a rocking chair with a high frame.

In FIG. 3, a top view schematically shows a rocking device with additional chairs on the sides.

In FIG. 4, a side view schematically shows the likely optimal position of the side chairs relative to the center of swing.

In FIG. 5, a rear view of the seat shows a shockproof insertion device on elastic rings with a cone-shaped elastic buffer.

In FIG. 6, a side view shows a shockproof insertion device on elastic rings with a cone-shaped elastic buffer.

In FIG. 7, a side view schematically shows the state of the shockproof insert in a compressed state.

In FIG. 8, a side view shows rocking chairs with visors above the seats.

In FIG. 9, a side view shows rockers with a movable canopy.

Rv is the force applied vertically;

n is the maximum distance from the seat cushion to the lower extreme point of the position of the handle;

h is the maximum distance from the seat cushion to the upper extreme point of the position of the handle;

c is the limit distance from the back of the seat to the nearest point on the position of the handle;

and - the greatest distance from the axis of swing to the support foot inside the frame;

b - distance from the axis of swing to the center of the seat;

l is the distance from the swing axis to the center of the chair;

ϕ is the angle of inclination of the shockproof insert;

This goal is achieved by the fact that the crossbar of the swing 1 is made composite (Fig. 1), consisting in the middle of a closed frame 1.1, based in the center on the swing axis 1.2.

Extenders 1.3, 1.4 are attached to the outer edges with seats 2 attached to the edges.

Bearing swing bearings axis 1.3 are mounted on a support frame 3.

At the same time, extension cords can be either single-profile 1.3 (conditionally shown on the right) or multi-profile 1.4 (conditionally shown on the left), creating a different visual effect.

Children on a swing 4 can swing both independently and with the help of a third child 5.

Child 5 becomes feet on the lower side inside the frame 1, which is the base for the legs, and holds with his hands either on the upper side of the frame, or on the side and, shifting his center of gravity to one or the other foot, helps not only compensate for the difference in weight 4 children sitting on the seats, but also swing comfortably at the maximum possible amplitude.

Perhaps the device on the frame of special grips 1.5, providing a comfortable grip with your hands.

Since the shoulder "a" of the application of additional force created by the child 5 is much smaller than the shoulder "b" from the axis 1.2 to the center 2, this force will not create dangerous power loads, and special shockproof inserts 6 attached to the seats from the bottom will absorb shock loads.

To increase the diversity of the game component, the crossbar 1 (Fig. 2) can be made high, where the child 5 can not only stand holding the sides of the frame, but also hang on his hands, holding the upper side of the frame 1. Inside the frame itself, the child 5 can not only standing, but also sitting on the underside of the frame.

The functionality and attractiveness of rocking chairs can be expanded through the comfortable involvement and participation of parents in children's entertainment.

To do this, on the side of the rocking chairs, on opposite sides of the extension cords, chairs 7 or benches 8 are installed symmetrically on a separate base (Fig. 3), while adults sitting on seats 7 or benches 8 can use vertical force exerted on the arms 9 mounted on extension cords 1.3 (on the right in FIG. 3) or directly to the elements of multidisciplinary extension cords (on the left in Fig. 3) swing the children sitting on the rocking chairs.

At the same time, chairs or benches do not restrict children from using frame 1.1 at the same time.

A comfortable distance "l" of the location of the chairs 7 or benches 8 from the swing axis 1.2, at which it is physiologically convenient to swing with a vertical force, is the distance at which the lower point of the handle 9 relative to the cushion of the chair 7 will be at a distance "n" less than or equal to 300 mm, and the top - the distance "h" is not more than 350 mm.

Effective shock insert 6 is arranged as follows. On the mounting plate 10 (Fig. 5 and 6) along the edges of the upper fastening elements 11 are fixed elastic rings 12, as an option from segments of multilayer rubber-fabric hoses for pumping liquids.

From the bottom to the rings 12 with the lower fastening elements 13, a support plate 14 is attached, between the rings 12 at least one elastic buffer 15 is installed at one end fixed on the mounting plate 10.

It is preferable to use a buffer 15 of a conical shape made of rubber.

The device operates as follows.

Using the mounting plate 10, the shockproof insert is fixed under the seat 2 so that the plane of the support plate 14 is at a certain angle ϕ to the longitudinal axis of the crossbar in a horizontal position.

The initial installation angle ϕ, depending on the height of the swing axis and the length of the crossbar, is selected so that at the moment of contact of the base plate with the surface of the pad, it is parallel to the surface of the pad.

The support plate 14, having a large contact area, can drastically reduce the specific pressure on the platform, and the buffer 15, in particular rubber, cone-shaped, abutting the support plate 14, perceives the impact force with a smooth increase in resistance and prevents dangerous bends of the retaining rings 12 (Fig. 7).

The area of the base plate 14 can be selected such that even at sites where sand is used as a shockproof coating, it will not sink into the sand.

In this case, the elastic rings 12 perform the function of positioning the plate 14 relative to the surface of the pad and the buffer, and the U-shaped bracket 16, rigidly connected to the supporting plate 14, which is rigidly connected to the support plate 14, on the one hand increases the rigidity of the plate 14, and on the other, eliminates the possibility of the buffer skew fifteen.

An additional shock-absorbing and anti-noise element may be a layer of elastic material 17 fixed to the sole of the support plate 14.

As a buffer, various springs or a pneumatic damper device containing suction valves and throttling holes can be used.

Such dampers can be diversified by installing in them various devices that make musical sounds.

Rocking chairs can be made more comfortable by installing height-adjustable swivel chairs.

This will allow those sitting to choose a comfortable position both in relation to the child sitting in the middle seat, and in relation to the partner sitting in the opposite chair.

The presence of modern ultralight and durable materials can allow you to create a rocking chair with various visual effects and enhanced functionality.

For this, for example, (Fig. 8) above the seats 2 or extension cord 1.3, solar plastic or canvas visors 17 can be fixed, and the visors can be mounted folding on the hinge 18.

The original visual effect can be created by installing on the frame (Fig. 9) a one-piece canopy 19 made of a plastic profile or linen stretched on a frame.

Thus, the proposed solution to the design of the rocking-balancer allows you to:

- increase safety due to the installation of effective shockproof inserts and eliminate the negative impact of rocking elements on the coverage of sites;

- to provide increased gaming attractiveness due to the active gaming complicity of other children in entertainment on rocking chairs;

- initiate a constructive and comfortable involvement of adults in the games and leisure of their children, increase motivation in favor of family leisure;

- implement a variety of forms of design solutions.
