Description

[Detailed description of the invention] This invention relates to a swing that has been improved with emphasis on ensuring the safety of children on board.

Generally, the range of swing of a swing is not regulated, so if the swing is made too large, there is a risk that children riding on the swing may fall, resulting in great danger.

Therefore, in order to avoid such a situation, in the case of a swing that has a swinging bench configuration on which multiple children can sit and sit facing each other, a swing with a seat suspension rod and a foot suspended from the lower end of the rod is used. The swinging angle formed with the footrest is set by installing a horizontal pipe at the lower end of the above-mentioned suspension rod, which abuts against or separates from the upper surface of the swinging end of the footrest when the swing swings. The swing range is regulated by

However, with such means, there is a major problem in that when the swing swings, the child's feet are likely to get caught between the horizontal pipe at the lower end of the hanging rod and the footrest. Furthermore, if the swing range of the swing is restricted by colliding the horizontal pipe with the footrest as described above, the shock at the time of collision, that is, when the swing stops instantaneously at the end of the swing stroke, will be reduced. This makes the ride uncomfortable, and the shock of the horizontal pipe causes the so-called swing, such as a footrest, to be destroyed at an early stage. As a structure for regulating the swing range of such a swing, for example, in the children's swing of U.S. Pat. There is a known configuration in which the spring is provided facing inward so that the spring directly collides with the suspension rod of the swing controller.

However, in the above configuration, since the pivoting motion of the hanging rod is directly received by the spring and the range of swinging (pivoting) is restricted, the holding piece and spring must be made large, and the hanging rod and spring are Since the gap between them is large, there is a risk of your hand getting caught if you are holding the hanging rod while standing up.

This device was devised to solve the above problems all at once, and its purpose is to allow users, such as infants, to safely and smoothly move the swing without getting caught in the damper, even if they grasp the upper part of the hanging rod. To provide a swing which improves safety and ride comfort by regulating the swinging (pivoting) range and inevitably assisting the swinging force of the swing.

A preferred embodiment of this invention will be described below with reference to the drawings. In the swing shown in FIG. 1, the swing support structure 1 has the illustrated configuration in which the upper ends of four poles 1a are integrally connected by a horizontal beam 1b having a planar rectangular frame shape.

Four suspension rods 3 are swingably suspended from parallel horizontal beams 1b via brackets 2 at the upper end of such a swing support structure 1.

The bracket 2 has two bracket pieces 2a and 2b that sandwich the horizontal beam 1b from above and below.
The bracket pieces 2a and 2b are attached to the horizontal beam 1b by tightening bolts V and nuts N at both ends thereof, and are fixed to the horizontal beam 1b with screws B for preventing rotation. There is. The bolts V, V are fixed on both sides of the bracket pieces 2a, 2b with their heads protruding downward,
In this embodiment, the heads of the bolts V, V are used as abutting portions for abutting against a damper member 8, which will be described later. Further, the bracket 2 has a horizontal pin P for connecting the hanging rod in its hanging portion, and the upper end eye portion 5 of the hanging rod 3 is rotatably fitted and held in this horizontal pin.

A damper holding piece 6 is integrally formed on the upper end eye portion 5 of the hanging rod 3 and extends to a spaced position below the tightening bolt V of the bracket 2.

A bottomed cylindrical damper holding tube 7 is vertically provided on the damper holding piece 6 and communicates with a through hole formed in the damper holding piece 6, and a damper member 8 is attached to this.

The damper member 8 includes a coil-shaped spring 9 that is fitted and held in a damper holding cylinder 7 and protrudes from an opening at its upper end, and a stopper piece that loosely passes through the spring and the center of the damper holding cylinder 7 and has a stopper piece at the lower end. 11 and an elevating rod 10 having a pressure receiving piece 12 at the upper end, this elevating rod has a spring 9
The structure is such that it is always biased upward. In the damper member 8, when the hanging rod 3 is in the vertical position, the pressure receiving piece 12 at the upper end touches the bracket 2.
The clamping bolt V is held in a spaced position below the clamping bolt V, and when the hanging rod 3 swings, the pressure receiving piece 12 collides with the lower end of the clamping bolt V to restrict the swinging range of the hanging rod. There is.

A seat body 13 and a footrest 14 spaced apart below the seat body 13 are suspended from the lower side of the suspension rod 3 in the same manner as before.

Next, the operation of the swing configured as described above will be explained. When the swing of the swing swings, when the swing of the hanging rod 3 that swings around the horizontal pin P of the bracket 2 reaches a predetermined magnitude, the pressure receiving piece 12 of the damper member 8 located on the side in the swing direction responds to this swing. the bracket tightening bolt V at the position shown. The spring 9 is compressed by the collision. Therefore, the swinging range of the suspension rod 3 is gradually restricted by the buffering action of the spring 9, and there is no possibility of a large shock occurring due to this restriction. Moreover, when the hanging rod 3 swings in the opposite direction from the swinging restriction position by the damper member 8, that is, from the swinging stroke end, the hanging rod 3 is moved in the swinging direction by the repulsive force of the compressed spring 9. energized. Therefore, the hanging rod 3, that is, the swing swings smoothly with a small forced rocking force, making the swing ideal for infants and the like.

Of course, this invention can be applied to a single-seater swing without changing the gist of the invention.

As described above, this invention exhibits the following excellent effects.

(1) The swing range of the swing can be regulated without any shock. Furthermore, since the damper member that regulates the swinging is provided at the upper end of the suspension rod, there is no fear that children riding the vehicle will get their feet caught, ensuring safety and ensuring a comfortable ride. It also gets better.

(2) The damper member is provided upward at the upper end of the hanging rod and faces the abutting protrusion of the upper end cross beam, so even if an infant or guardian holds the hanging rod of the swing, the damper member will not move. There is no risk of a hand getting caught between the member and the abutting protrusion, resulting in extremely high safety.

(3) Furthermore, the damper member assists the swinging of the hanging rod in the opposite direction from the end of the swinging stroke by the repulsive force of the spring, so that a child or the like can easily and smoothly swing the swing with a light force.

Note that the swing according to this invention may have a structure in which only the seat plate is suspended by two hanging rods, and can be implemented with various modifications without changing the gist.
