Abstract

The invention discloses a safe swing which relates to the field of child toys and particularly relates to the field of swings. For most of rope-connected swings, only one rope is arranged, once an accident occurs, the consequence is very serious. In order to enhance the safe performance of the swing, the safe swing is designed. According to a technical scheme, a fixed pulley is fixed to a transverse bar; two swing ropes are sleeved in grooves of the fixed pulley; each swing rope is tied with a knot below the fixed pulley; a transverse plate of the swing is improved to be a chair; the two swing ropes are changed to four sections after bypassing the fixed pulley; the four sections of swing ropes are connected to four corners of the chair; and cotton tape holes are formed in the upper ends in the left and right directions of the chair. The safe swing has the following beneficial effects that the fixed pulley of the transverse bar is beneficial to friction reduction, the swing ropes are fixed below the fixed pulley, and the relative movement of the fixed pulley and the ropes is reduced, so that the friction is reduced; the two ropes are fixed so as to be changed to four ropes; and the fixing role of the cotton tape holes to the ropes is beneficial to reduction of impact to the chair.

Description

A kind of safer swing

Technical field

The present invention relates to toy for children field, particularly swing.

Background technology

Swing generally only has a fixing point, the swing that most of rope connects, and every one end only has a rope, swing generally swings higher, breaks, greatly may cause and land if rope occurs in high-altitude, light then abrade, heavy then badly bruised from flogging, fractured bone, even threat to life.

Most of swing adopts more sturdy rope, swing is generally outdoor toy, rope is subject to the corrosion brought of exposing to the sun and rain, be subject to waving the frictionally damage brought, cannot be known for sure the abrasion condition of rope, and can only change rope by rule of thumb, who can not ensure its absolute safety, once meet accident, its consequence is suitable serious.

Summary of the invention

For strengthening the security performance of swing, the present invention designs a kind of safer swing.

The technical scheme that the present invention realizes goal of the invention employing is: a kind of safer swing, comprise support bar, cross bar, swing rope, fixed pulley and chair, it is characterized in that: cross bar is fixed a fixed pulley, two swing rope slings are in the groove of fixed pulley, two swing ropes are made a call to a knot and are fixed or bundle fixing below fixed pulley, guarantee the close contact of swing rope and fixed pulley; The transverse slat of swing is improved to a chair, four sections are become after fixed pulley walked around by two swing ropes, four sections of swing ropes are connected respectively to four angles of chair, in the upper end of the left and right directions of chair, cloth is with holes to be connected two of the left side sections of swing ropes and fixes with swing rope, another cloth is with holes to be connected two of the right sections of swing ropes and fixes with swing rope, and cloth is with holes to be stretched out for arm.

The invention has the beneficial effects as follows: it is come by the rolling of ball that the fixed pulley of cross bar rotates, and rolling friction is little, is conducive to reducing the damage rubbing and bring; Two swing rope slings are in the groove of fixed pulley, and swing rope makes a call to one below fixed pulley, and knot is fixing or binding is fixing, fixedly guarantees the close contact of swing rope and fixed pulley, reduces the translation between fixed pulley and rope, thus reduce friction; Fix and two ropes are become independently four, after a broke wherein, also have three ropes to use, can effectively strengthen its security performance; The transverse slat of swing is improved to a chair, is conducive to the comfortableness of swing; Become four after fixed pulley walked around by two swing ropes, four swing ropes are connected to four angles of chair, are conducive to the stability ensureing chair; There is cloth with holes in the upper end of the left and right directions of chair, cloth is with holes to be stretched out for arm, hand catches the rope of upper end, wherein a rope is as resolutely fallen, and relies on the strength of arm and hand, can reduce the injury that may bring health, strengthen its security performance, if a broke of cloth upper end with holes falls, the cloth fixation to rope with holes, is conducive to reducing the impact to seat.

Detailed description of the invention

A kind of safer swing, identical with common swing is, there is support bar 1, cross bar 2, swing rope 4, connected by connecting rod 8 in bottom between the support bar 1 of between support bar 1 and both sides, to strengthen its firm performance, be with common swing difference: cross bar 2 is fixed a fixed pulley 3, swing rope 4 is enclosed within the groove of fixed pulley 3, swing rope 4 is improved to two ropes by a rope of common swing, a knot made a call to by swing rope 4 below fixed pulley 3, be called fixed knot 5, fixed knot 5 also can be that binding is fixing, the transverse slat of swing is improved to a chair 7, four sections are become after fixed pulley walked around by two swing ropes 4, four sections of swing ropes are connected to four angles of chair 7, in the upper end of the left and right directions of chair, two of the left side sections of ropes connect and fix with rope by a cloth with holes 6, two of the right sections of ropes connect and fix with rope by another cloth with holes 6, cloth with holes 6 stretches out for arm.
