CN2218469Y - Anti-obstacle slide fastener button - Google Patents

Abstract

The utility model discloses an anti-obstacle slide fastener button, which is composed of an upper button sheet (1), a lower button sheet (2), an upright post (3), a pull ring (4), and an anti-obstacle upper baffle plate (5) and an anti-obstacle lower baffle plate (6) which are respectively arranged on the upper button sheet and the lower button sheet. The front end faces of the upper baffle plate and the lower baffle plate which are arranged on the slide fastener button are made into a saddle structure which is concave downwards along the middle shaft line of the slide fastener button. When a slide fastener is used, the saddle structure of the baffle plates can make obstacle objects baffled effectively at the outer side of the tooth slits of the slide fastener, such as clothes, the soft sides of ornaments, etc.

Description

Anti-obstacle slide fastener

The invention belongs to fastening connector, the especially clothing of daily goods, the case and bag based article slide fastener of slide fastener.

For solving the slide fastener goods in use easily by the problem of flexible foreign matter jam, Chinese patent CN94227206.4 discloses a kind of anti-obstacle slide fastener, on cramp up and down, be provided with the convex push pedal and snap in the slide fastener seam to stop flexible foreign matter, solved stuck issue to a large extent, but because the convex push pedal is in promoting the foreign matter process, there is cross component force, causes its anti-obstacle effect to be subjected to some influences.

The purpose of this utility model is that anti-obstacle slide fastener is further improved, and makes it to have more good antifouling function.

The purpose of this utility model is to realize by following means.

By on cramp, down cramp, column, draw ring and place cramp respectively and following cramp on anti-obstacle overhead gage and the anti-obstacle slide fastener formed of lower baffle plate on, the front end face of overhead gage and lower baffle plate is the shape of a saddle structure recessed down along the slide fastener axis.

After having adopted structure as above, when the slide fastener drawing runs into foreign matter, because the thrust of shape of a saddle end face structure is made power, foreign matter is suffered consistent with slide fastener pulling direction with joint efforts, do not have cross component force to exist, make foreign matter be pushed to the place ahead, prevented the possibility of foreign matter jam up hill and dale with the motion of cuff link.

Description of drawings is as follows:

Fig. 1 is the utility model embodiment stereogram.

Fig. 2 is A-A cutaway view of Fig. 1.

Fig. 3 is another example stereogram of the present utility model.

Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.

In Fig. 1 and Fig. 2,1 is last cramp, and 2 are following cramp, 3 is column, 4 is draw ring, and anti-obstacle overhead gage 5 and lower baffle plate 6 combine as a whole with last cramp and following cramp in fact respectively, and the front end face of overhead gage and lower baffle plate is the shape of a saddle structure 7 recessed down along the slide fastener axis.Can see that in Fig. 2 descending most of column 3 and shape of a saddle structure has a segment distance 9 between the recess 8, column does not reach foreign matter like this, has more effectively prevented jam.

The shape of a saddle curvature of last lower baffle plate can equate, also can be unequal, and the embodiment situation that Fig. 3 represents when being unequal.

For preventing that foreign matter from forming jam from getting in sprocket and the cuff link chamber between the slit of cramp dual-side up and down, can manufacture and design the side of going up cramp the curved button limit (10) that folds down cramp.

Claims (4)

1, a kind of anti-obstacle slide fastener, by last cramp (1), down cramp (2), column (3), draw ring (4) and place cramp respectively and following cramp on anti-obstacle overhead gage (5) and lower baffle plate (6) form, it is characterized in that the front end face of overhead gage and lower baffle plate is the shape of a saddle structure (7) recessed down along the slide fastener axis.

2, the slide fastener according to claim 1 is characterized in that, descending most of described column (3) and shape of a saddle structure (7) has a distance (9) between the recess (8).

3, the slide fastener according to claim 1 is characterized in that, the saddle-shaped curvature of described overhead gage (1) and lower baffle plate (2) can equate, also can be unequal.

4, the slide fastener according to claim 1 is characterized in that the side of last cramp (1) is the curved button limit (10) that folds down cramp.
