Abstract

Hook for laces of footwear, characterized in that it is made up of a first and second elements (1, 2) having coaxial portions (13, 20) and engaged to each other, the first element (1) intended to be fixed to the vamp of a shoe, while the second (2) is pivotable about the common axis (b) of the coaxial portions: the coaxial portions (13, 20) of said elements (1, 2) delimiting, in cooperation with each other, a bore (4) for the passage of a lace which results either fully closed or open on one side, depending on the mutual angular position of the two elements (1, 2).

Description

The hook of lace-guiding

The invention relates to the hook of shoestring, the hook of a kind of lace-guiding on the shoes of wearing especially for anti-accident.

As you know, those are having the footwear of wearing in the unexpected dangerous situation working environment must have special feature, blocked by certain of the motor vehicle in the working environment, carriage or other airborne load comprising a pin as if the operator, perhaps poisonous or high-temp liquid leak dangerous the time, must the back take place or carry out middle disengagement in accident as quickly as possible.

The hook that main purpose of the present invention provides a kind of practicality, safety, low cost and can easily undo shoelaces, thus can take off footwear soon.

Just can reach this target according to the present invention, promptly adopt such conception of species: produce a kind of device with the disclosed characteristic of claim 1, further feature of the present invention is set in the dependent claims.

From the advantage of the present invention's generation be, in case of emergency, can undo shoelaces the easiest, the soonest and safely, can guarantee the suitable degree of tightness of shoestring under normal circumstances simultaneously.And, according to shoestring hook of the present invention, to make easily, cost is low, and is still very reliable after long-time the use.

Behind the specification and the accompanying drawing as embodiments of the invention below reading, any one those skilled in the art all can be understood these and other advantage of the present invention and feature well, but can not think to have limited significance, wherein:

Fig. 1 be according to the present invention under the situation of closing the preceding lateral perspective view of hook;

Fig. 2 is the bottom perspective view of hook shown in Figure 1;

Fig. 3 is the side view of hook shown in Figure 1; And

Fig. 4 is the sectional view of the second parts front portion.

Its basic structure is dwindled, and with reference to accompanying drawing, shoe hook of the present invention is made up of first and second (1,2) parts.First parts (1) are installed on the predetermined point on the vamp (3).For example, available rivet of above-mentioned first parts (1) or similar thing pass aperture (10) and are installed on the vamp (3), and this aperture that is to say in corresponding place, same first parts (1) back, corresponding to the part of exposing, there is a surface (12) to contact with vamp (3).Above-mentioned first parts (1) also have a previous section (13), and its profile is hook shape substantially, that is to say, is a circular shape, and its extension angle is greater than 180 °.The circular arc concave surface is towards above-mentioned surface (12).For example, the available extrusion process of above-mentioned first parts (1) is made into a monoblock.

Second parts (2) of this hook also have a previous section (20) and aft section (21).It makes a moulded parts with resembling nylon 66 such plastics.The previous section (20) of above-mentioned second parts (2) has crooked profile, that is to say, and be a circular arc, its extension angle is greater than 180 °.The concave surface of the previous section (20) of second parts (2) is towards the axle of the longitudinal extension of aft section (21).Be provided with an otch (22) in the corresponding bonding pad (200) of the front-back of second parts (2) part (20,21), its width (a) just in time equates with the width of first parts (1) previous sections (13).

In fact, from the side, each of above-mentioned two parts (1,2) all resembles the shape of a question mark.

The overall diameter of second parts (2) previous sections (20) is identical with the interior diameter of first parts (1) previous sections (13), like this, wants fine introduction as following, and these two parts can slide mutually.

When the appropriate section (11) that leans against first parts (1) when the aft section (21) of second parts (2) goes up, as shown in figures 1 and 3, two previous sections (13 of these two parts, 20) separately concave surface mutually to the time, just define a transverse holes (4), the axle in hole (4) is designated as (b) in Fig. 3, the shoestring (not shown) passes the footwear that just can fasten in it on pin.

The aft section (21) of second parts (2) is mentioned shown in Fig. 3 arrow (U), so just can obtain result as shown in Figure 2, previous section (20) is done corresponding rotation around axle (b) just makes a side of endoporus (4) open, this side just in time is exactly to go up that side of hook towards vamp (3), shoestring just can be deviate from from hook like this, has unclamped shoestring.

For two side, advantageously, the previous section (20) of second parts (2) has an outstanding seamed edge (23), between with the dual-side of a part (20), form a groove (24), when second parts (2) when above-mentioned axle (b) rotates, more slightly frictional force ground is gone up at the inner surface (130) of first parts (1) and is slided, thereby makes stability of rotation.

Also advantageously, as shown in Figure 4, each side in (20) two sides of second parts (2) previous section will converge to groove (24), and this groove is limited by above-mentioned seamed edge (23).

In addition, the aft section (21) of second parts (2) is longer than the corresponding part (11) of first parts (1), thus second parts just give prominence to towards the back, thereby a finger that need only a hand just can carry out above-mentioned rotation at an easy rate.Perhaps, the aft section (21) of second parts (2) is shorter than the corresponding part (11) of first parts (1), without holding the back, holds its both sides with two fingers of a hand and gets final product.

Two parts (1,2) are installed as follows:

Second parts (2) are placed on first parts (1), the previous section (20) of the corresponding side of such second parts is located in a side of the previous section (13) of first parts (1), the bonding pad (200) that the forward and backward part of first parts (2) is coupled together will be positioned between the two ends (131,132) of first parts front arc part (13).Then, some pressure a little on second parts (2), it is pushed to first parts, thereby make above-mentioned side camber, that is to say, make relevant edge (23) bending, at first in the direction of groove (24), then in the opposite direction, the inner surface of such first parts (1) previous sections (13) will contact with the groove (24) of second parts.

At last, by the end (131) of first parts (1) previous sections (13) is passed the otch (22) of second parts (2), thereby second parts (2) are rotated around above-mentioned axle (b).

In a word, according to the present invention, the shoestring hook is by two parts (1,2) form, they have same shaft portion (13,20) and are bonded with each other, first parts (1) will be fixed on the vamp, and second parts (2) can rotate around the total axle (b) with shaft portion: the same shaft portion (13,20) of above-mentioned parts (1,2) is cooperated with each other, limit the hole (4) that a shoestring passes through, according to the mutual angle position of two parts (1,2), this hole (4) are closed fully or are opened in a side.

Above introduction the safety operation and the simple structure of the hook of suggestion summarily have been described, this hook has only two members to form, and does not show or without any need for auxiliary part, as is used for the thing of inner pin that connects and so on.
