Abstract
ABSTRACT OF THE DISCLOSURE:
Improved buckle in particular a sliding buckle which principally consists of a clasp, a transverse connection extending through the clasp, and a toothing installed along one side of the buckle on the front transverse part of the clasp. The toothing is situated on top of a flange protruding out of the surface of the buckle whereby the teeth thus formed show a triangular form in a perpendicular longitudinal section with regard to the buckle, of which one flank stands perpendicular on the surface of the buckle, while a second flank is slanting and extends from the perpendicular flank to the opening of the clasp.

Description
~L3~7879 The present invention relates to an i.mproved buckle, more especially A sliding buckle.
In particular the invention has a buckle as object which enables a very efficient clamping of a belt extremity, for example of a band.
According to the present invention, there is provided an improved buckle which principally consists of a clasp having an opening and comprising a front transverse part in front o~ the opening; a transverse connection extending through the opening of the clasp; and a first toothing installed along one cide of the buckle on a flange protruding out of the sur~ace o~ the buckle and provided on the ~ront transverse part oE the clasp, characterised in that said fir~t toothing is situated on top o~ the flange, whereby teeth o~ 6aid fir6-t toothing show a triangular ~orm in a perpendicular longitudinal section with regard to the buckle, each tooth having one flank which stands perpendicular on the surface of the buckle and a second flank which is slanting and extends f rom the perpendicular flan~ to the opening of the clasp.
This buckle permits that the free extremity of a belt can be guided over 270 degrees around the transverse connection consequently to pass between the clasp and the rising part of the belt.
Through the tightening of the belt the advantageous effect develops that the free extremity i5 pressed against the aforementioned toothing by means of the rising part of the belt through which the force with which the belt is clamped in the buckle i5 notably increased.
: ' . , , ........... ', ~ , :
. '~ ' , . ~ - 2 -~327879 According to a preferred embodiment, one or more further toothings are also installed on the transverse connection, which extends straight through the buckle, in com~ination with the aforementioned toothing, such to still greater c~unt~ract the release of the tightene~ be:Lt in the buckle.
In order to show better the characteristics according to the present invention, some preferred embo~iments are described hereafter, as examples and without any restrictive character, with reference to the enclosed drawings, in which:
figure 1 shows the buckle accordiny to the invention;
figure 2 shows a cross-section accord.ing to line II-II in figure 1;
figure 3 shows a cross-section according to line III-III in figure 2;
figure 4 shows a variant;
figure 5 shows a vi~w according to arrow F5 in figure 4;
fiyure 6 shows another variant;
fi~ure 7 shows a cross-section according to line VII-VII in figure ~.
As shown in igures 1 and 2 the buckle 1 principally consists of a preferably practically rectangular clas~.) 2 which is connected close to one extremity 3 with a belt 4, a transverse connection 5 extending through the clasp ~, and a toothing 8 installed along at least one side 6 of the buckle 2 on the front transverse part 7 of 'che clasp 2.
The buckle permits that the Eree extremity 9 of the belt 4 is guided over 270 degrees around the transverse connection 5, consequently to pass between the front transverse part 7 and the rising part 10 of the belt 4.
With the tightening of the belt 4 by pulling on the freQ
extremity 9, the latter is, ~y means of the part 1 n .. ..
:~327879 pressed with force Oll the toothing 8 such that apart from the normal frictional resistance which exists in the buckle, an extra .resistance force is offered ~y the tootl1ing 8 acting on the free extremity 9. The optimum .lampinc3 effect is obtained when the toothing 8 is precisely next to the inner edge 11 of ~he clasp 2. In order still to increase the effect the toothin~ 8 is preferably situated 0l1 top of a flange 12 protruding out of t.he surface of the buckle 1, all of which as shown in figures 2 and 3.
As still visible in figure 3 the toothing 8 ~referably consists of a series o pointed teeth 13.
As ~shown in figure 2 these teeth 13 disE)lay a triangular form in a perpendicular longitudinal section with regard to the buckle, whereby one flank 14 stands ~rpendicular on the surface of the buckle 1, while a second flank 15 is slanting and extends from the perpendicular flank 14 to the opening 16 of the clasp 2. By this it is achieved that the belt 4 easily slides over the toothing 8 when this is tightened, but can with difficulty move in the opposlte manner due to the teeth 13 operating as barbs in this case.
. . .
As shown in figures 4 and 5 a second toothin~ 17 Call also be provided on the transverse connection 5, in combination with the aforelnentioned toothing 8. The toothing 17 preferable con3is.s o~ teeth 18 which extend out of the aforementioned opening 16.
In the most pref~rred embodiment, a~cording to figures 6 and 7 use is also niade oE a third toothing 19 in addition to the aforementioned toothings 8 and 17 which like the toothing 17 is installed on the transverse connection 5.
It is found on the side 20 of the buckle 1 which is situated opposite to the aforementioned side ~ where the toothing 8 is found. The second and third toothings 17 and 19 are preferably situated next to one same edge 21 of the transverse connection 5.
,, : , , , . ~
. ~ 4 ~ 1327~79 The ~uckle according to the invention also offers the advantage that it can simply be manufactured of plastic, such as an injection moulding. This also of~ers the advantage that the buckle 1 can be permanently moulded to the belt 4 by means of a suitabl~ extension 22, as visible in figures 1 and 2.
The buckle 1 permits particularly yood tighter.ing possibilities when use is made o a belt 4 consisting of a woven band, for example of synthetic fibre, 3uch as nylon.
It i~ clear that the toothing 8 can also be installed along both sides 6 and 20 of the buckle 1. Such offers the advantage that when attaching the belt specific attention need not be paid to by which side the free extremity 9 mu~l. first be guided through tlle buckle 2.
As visible in the figures 2, 4 and 6 the parts o~ the buckle opening 16 situated along both sides of the transverse connection 5 are preferably produced widened in the direction of their extremities along which the belt is introduced, such to facilitate putting the belt 4 into the clasp 2.
The present invention is in no way restricted to the embodiments described as examples and shown in the drawings, but such improved buckle may be developed m all kinds of forms and dimensions, without departing rom the scope of the present invention.
