Abstract

The utility model relates to a safe vertebra sleeve with pull ropes, composed of two half vertebra sleeves. The lower part of every half vertebra sleeve is embedded with a magnet, the upper part of every half vertebra sleeve is provided for every pull rope to penetrate a knot, two half vertebra sleeves are combined together, and two half vertebra sleeves are combined into a whole vertebra sleeve by the magnetic force. When outside force acts on two pull ropes, the vertebra sleeve is split into two half vertebra sleeves, and in this way, the asphyxiation danger possibly happen after an infant put the head into two pull ropes.

Description

Safety curtain cord appurtenance

The utility model relates to stay cord vertebra cover, refers in particular to be used to control the stay cord vertebra cover that curtain, curtain etc. open and close.

The stay cord tail end that is used in curtain, curtain, blind window traditionally all has a vertebra cover (10) as depicted in figs. 1 and 2, the structure of tow line (14) that it is made up of body (12) and bifilar stay cord (16), body (12) is a ducted body, in have living space (18) hold the knot of two stay cords (16).This kind vertebra cover is made with use all very convenient, but potential hazards are arranged in use, be that general family all is seated in the window limit to infanette, child sees novel thing and all can grab and play, even two stay cords (16) are opened be enclosed within on the neck, and then cause child's death by suffocation, so for the family that baby or child are arranged, traditional vertebra cover is a kind of product of potential danger.

The purpose of this utility model is the major defect at above-mentioned vertebra cover, a kind of safe stay cord vertebra cover is proposed, this vertebra cover is made up of two parts, during normal the use is an integral body, when the people separates the application of force to two strands of stay cords, the vertebra cover can be divided into two automatically, has exempted above-mentioned child and has been inserted in the danger that is suffocated behind two strands.

The technical solution of the utility model is that original whole vertebra cover is divided into two and half vertebra covers, per one stay cord of half vertebra cover control, and in the vertebra cover, permanent magnet is installed, when using at ordinary times, two blocks of magnet in the two and half vertebras covers inhale mutually form as a whole, but when in two strands when stressed, the stressed separation of magnet, two and half vertebras cover also and then separates, and has avoided danger.

Details are as follows in conjunction with the accompanying drawings in detailed description of the present utility model, wherein:

Fig. 1 is traditional integral vertebra cover schematic perspective view;

Fig. 2 is the structure cutaway view of whole vertebra cover;

Fig. 3 is the schematic perspective view of safe stay cord vertebra cover;

Fig. 4 is that two and half vertebras cover separates schematic diagram;

Fig. 5 is the exploded view of safe stay cord vertebra cover;

Fig. 6 is added with the safe stay cord vertebra cover schematic diagram that joggle closes;

Fig. 7 is the decomposing schematic representation of Fig. 6.

Fig. 1 and Fig. 2 are present widely used stay cord vertebra cover (10), there is a space (18) centre of the body (12) of this vertebra cover, be used to hold the knot of two strands of stay cords (16), two strands of stay cords (16) are stretched out by vertebra cover top circular hole forms a structure of tow line (14).Show and as seen,, be easy to be inserted in rope sling, cause the danger of death by suffocation just as hanging oneself if the child is inserted in head between two strands of stay cords (16).

By Fig. 3,4,5 as seen, and the design's safe stay cord vertebra cover (20) is made of one half vertebras cover and magnetic element (22).Each half vertebra cover all has one and half vertebra shape bodies (21), the interior bottom of body (21) utilizes the elasticity lug (24) of being located at plane opening (23) edge to be embedded with magnet (22), top is a space (26) that can hold one stay cord (27) knot, two and half vertebras are linked in a time-out, and the plane opening (23) of two and half vertebras cover is because the effect of magnetic force becomes a whole vertebra cover (20) as shown in Figure 3.If applying external force (when the neck that the child is arranged accidentally is enclosed between two strands) between two strands of stay cords, then vertebra cover (20) can separate two and half vertebra covers as shown in Figure 4 voluntarily, has eliminated hazards.

Fig. 6 and Fig. 7 are to put at above-mentioned safe stay cord vertebra to increase a pair of joggle and close, make like this two and half vertebras cover in conjunction with convenient effectively.The vertebra cover (30) that has the tenon combination, form by two and half vertebras cover, the bottom of the opening (39) of the body (31) of each half vertebra cover is provided with the magnet (35) of elasticity lug (34) setting-in, upper space (38) pierces into the knotting of aperture (36) back except that being used to hold stay cord (37), one tenon (32) and a blind mortise (33) also are housed, and the corresponding coupling of tenon of two and half vertebras cover with the blind mortise position, when two and half vertebras cover is inhaled together owing to the effect of magnet (35), because the effect of a pair of tenon and blind mortise makes two openings (39) can correctly close the position.But when making, must design tenon quite shortly, except having positioning action, must not hinder at stressed latter two half vertebra of stay cord and overlap rapid separating, otherwise can influence the design's security.

Therefore the design's vertebra cover compares with traditional vertebra cover, eliminated the careless labour contractor of child and stretched into issuable danger behind two strands of stay cords, therefore is perfectly safe.

Claims

1, a kind of safe stay cord vertebra cover is characterized by this vertebra cover and is made up of the body of two and half vertebras cover, and the interior bottom of this body is embedded with magnet, and top is the space that holds one stay cord knot, the two halves vertebra is linked in the vertebra cover that becomes as a whole shape together.

2,, it is characterized by in the body of half vertebra cover and establish a pair of tenon combination of forming by blind mortise and tenon by the described safe stay cord vertebra cover of claim 1.

3,, it is characterized by on the limit of half vertebra cover and offer the elasticity lug with setting-in magnet by the described safe stay cord vertebra cover of claim 1.
