Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a belt end fixing device provided in a buckle for fixing the end of a belt.

<Prior art> As a belt end fixing device for such a buckle, a pair of opposing pieces each having a needle on opposing surfaces protruding from one end of the buckle to pierce the end of the belt is used. Japanese Utility Model Publication No. 52-14120 discloses a type in which a cylindrical slider is fitted on the outside of the belt, and the needles of each opposing piece are used to stab and fix the ends of the belt from the front and back.

<Problem to be solved by the invention> The above fixing device fixes the belt by stabbing the belt from the front and back with the needles of the pair of opposing pieces, which causes holes in the belt from being punctured by the needles, causing damage and damage between the opposing pieces. If a strong force is applied to the belt to try to pull it out, there is a risk that the belt will tear at the point where the needle pierced it and come out from between the opposing pieces. Furthermore, the end of the belt
When initially inserting the needle between a pair of opposing pieces up to the base of the opposing pieces, it is difficult to insert because the needle gets in the way.

<Means for solving the problem> Therefore, the present invention is capable of fixing the end of the belt strongly without causing scratches such as needle pricking on the belt, and furthermore, it is easy to insert the end of the belt for fixation. It was developed in such a way that it can be easily done without any obstacles, and as a belt end fixing device for the buckle, the end of the belt can be inserted into one end of the buckle body molded from plastic. A hollow cylindrical frame is provided protrudingly provided, and a cylindrical slider having a hollow portion that fits outside the cylindrical frame via a connection portion that is easily torn apart is protruded from the tip of the cylindrical frame. , one of the two wide surfaces facing the two flat surfaces of the end of the belt inserted into the hollow hole has an inner surface flush with the inner surface of the wide surface, and an outer surface with an uphill slope toward the buckle body. has a cam surface of
A tongue-shaped elastic blade whose width is narrower than the width of the belt is provided through a U-shaped cut-off hole, and an opening with a shape and size corresponding to the elastic blade is provided on the other wide side. shall be.

<Example> An illustrated embodiment of the present invention will be described below.

15 is a buckle body made of plastic having a removable connector, which is removably connected to another main body to which a belt is separately attached;
It may be a buckle such as a stability belt for securing the body to an aircraft seat.

A substrate 16 integrally projects from one end of the buckle body 15. On one side of the substrate 16, guide protrusions 17, 17A are provided along both sides, and a stopper protrusion 18 is protruded along the boundary with the main body 15, and a depression 16 is surrounded on three sides by these three protrusions. ′
has been formed.

The guide protrusions 17, 17 are provided with protrusions 19, 19A that protrude opposite each other, and the recesses 1
At the center of the bottom of the belt 6', an engaging protrusion 20 having a width narrower than the end 9 of the belt to be fixed is provided. The circumferential side surface 21 of this engagement protrusion 20 is inclined, so that in this embodiment the engagement protrusion 20 has a pyramidal shape. Although the upper surface of the engagement protrusion 20 is flat, parallel jagged or granular protrusions may be provided so as to bite into the end of the belt.

23 is a cover plate made of plastic that has the same shape and size as the depression 16' on the board, and has a thickness similar to that of the depression 16'.
thinner than the depth of

In this embodiment, the cover plate 23 has at least one string-like body (in this embodiment, two string-like bodies 24, 2
4A), it is formed in a connected state with the substrate 16, but it is also possible to form it in a connected state with one or several tearable connecting parts, and then tear the connecting parts later.

The cover plate 23 has an opening 25 in the center with a size and shape corresponding to the engaging protrusion 20, and cutouts 26, 26A corresponding to the protrusions 19, 19A are provided on both sides.

To fix the end part 9 of the belt, pass the end part 9 between the string-like bodies 24, 24A, and attach the guide protrusion 17, 1
7A and the stopper protrusion 18 into the recess 16' of the base plate 16. Then, the cover plate 23 is placed on the end 9 of the belt so as to overlap the recess 16', the opening 25 is made to face the engagement protrusion 20, and the notch 26 is made to face the protrusion 19. Press the plate 23 towards the recess 16'. As a result, the notches 26, 26A are replaced by the protrusions 19, 19A.
The end portion 9 of the belt is pushed into the opening 25 by the engaging protrusion 20, deformed in both the longitudinal direction and the width direction (see FIGS. 10 and 11), and then fixed.

<Effect of the invention> According to the invention, the depression 1 of the substrate surrounded on three sides
Since the end 9 of the belt is fitted into 6', the end of the belt can be fitted into the recess without any hindrance.

Then, the end of the belt can be easily fixed by simply placing the cover plate 23 on the end of the belt, overlapping it with the recess, and pressing it toward the recess in this state. Since it only deforms in both directions, the belt will not be damaged, and even if the belt is pulled, it will not come off the buckle body.
