[0001] The present invention relates to a lacing cleat for a laced fastening comprising
a first and a second cheek which are disposed side by side and between which a channel
is defined. It is known to make footwear with a laced fastening in which the lace
is guided through suitable cleats. The surfaces of known cleats offer a certain friction
to the sliding of the lace, making it very difficult to fasten the lace of the fastening
with the desired force.
[0002] A primary object of the present invention is to provide lacing cleats which are designed
structurally and functionally to offer less friction to the sliding of the lace.
[0003] Another object of the invention is to provide a cleat which can restrain the lace
once it is engaged in the channel. A further object is to provide a cleat which, whilst
achieving the advantages set out above, can be produced at low cost.
[0004] One of the chief objects of the invention is to provide a cleat which is particularly
strong and permits both conventional lacing and lacing with a purchase effect, and
which is suitable for clamping the lace.
[0005] These and other objects described in detail below are achieved by a lacing cleat
formed in accordance with the following claims.
[0006] The characteristics and advantages of the invention will become clearer from the
following detailed description of two preferred embodiments thereof, given by way
of non-limiting example, with reference to the appended drawings, in which:
Figures 1 and 2 are a plan view and a longitudinal section, respectively, of a first
embodiment of the lacing cleat according to the invention,
Figures 3 and 4 are views of a second embodiment of the lacing cleat according to
the invention, corresponding to Figures 1 and 2, respectively,
Figure 5 shows a possible use of the cleats of the preceding drawings.
[0007] In Figures 1 and 2, a first embodiment of a lacing cleat formed in accordance with
the present invention is generally indicated 1. The cleat 1 comprises an attachment
plate 2 through which one or more holes 3 extend and by which the cleat is attached
to a respective flap 3a, 3b of a footwear upper (Figure 5) by means of rivets 3c or
the like.
[0008] The plate 2 is extended to form a first and a second cheek 4, 5 which jointly define
a channel 6 closed by an end portion 7 and open at the opposite end, that is, at an
opening 9.
[0009] A cylindrical, pin-like appendage 10 extends between the cheeks 4, 5 and is preferably
formed by drawing of the central region of the first cheek 4 towards the second cheek
5.
[0010] The appendage 10 has a tubular shape, open at both axial ends, and preferably opens
beyond the second cheek 5 in the region of a hole 10a thereof, without, however, any
mechanical connection between the end of the appendage 10 and the second cheek.
[0011] The surface of the end 7 of the channel 6 and the opposite surface of the appendage
10 define, respectively, a second and a first lacing surface on which a lace 11 can
be guided for sliding as described further below.
[0012] A narrow section is formed at the opening 9 of the channel 6 and is defined by the
two cheeks 4, 5 which have, respectively, a projection 13 and a lip 14 facing one
another and projecting towards the interior of the channel 6 in order to restrict
its opening. This narrow section constitutes a restraining means for holding the lace
11 against the first lacing surface of the appendage 10 once it is engaged in the
cleat 1.
[0013] It should be pointed out that, since the cheeks 4, 5 are connected to one another
solely at the end 7 of the channel 6, they have a limited ability to move apart resiliently
which, together with the resilient deformability of the lace, allows the latter to
pass through the opening 9 of the channel 6 in order to be engaged in the cleat 1
where it remains held until it is forced out of the channel. Once the lace is arranged
for lacing, it therefore remains in its position of engagement in the cleats until
it is deliberately removed.
[0014] Finally, it should be noted that the second cheek 5 has a plurality of reinforcing
ribs 15 projecting in relief towards the inside of the channel 6, towards the other
cheek 4. The ribs 15 extend approximately radially relative to the axis of the appendage
10.
[0015] With reference now to Figures 3 and 4, a second embodiment of the cleat formed in
accordance with the present invention is indicated 20. Details similar to those of
the previous embodiment are labelled with the same reference numerals.
[0016] Unlike the cleat 1, the cleat 20 has a pulley 21 mounted idly on the appendage 10
which, in this embodiment, constitutes the pin of the pulley. The first lacing surface
is therefore defined on the race 22 of the pulley 21. The sliding friction between
the lace and the cleat is thus transformed into rolling friction, further improving
the ability of the lace to slide.
[0017] It should be noted that, in the embodiment 20, there is a single hole 3 in the attachment
plate 2. The cleat is thus mounted on the corresponding flap of the upper by a single
rivet 3c, permitting limited orientation of the cleat under load. It should be understood
that both of the embodiments proposed may be provided with attachment plates with
one or more holes according to need.
[0018] In normal use, a lace 11 is engaged in the cleat 1 or 20 through the opening 9 so
as to bear in sliding contact on the first lacing surface defined on the appendage
10 or on the race of the pulley 21, respectively. If it is desired to achieve a greater
tightening load for a given tension applied to the ends of the lace and, at the same
time, a clamping of the lace, in terms of greater resistance offered to the release
of the lacing, the lace 11 can be passed through the lacing cleats in the manner shown
in Figure 5. Typically, this solution is implemented in the pairs of cleats which
enclose the instep of the foot. The lace coming from the lower portion or toe of the
footwear is first inserted against the end surface 7 of the channel 6 of one of the
cleats 20 and is then passed over the appendage 10 or pulley 21 of the opposite cleat
20. A connection with purchase is thus achieved between the cleats and amplifies the
tightening and clamping force, or opposes the release of the lace under load. The
invention thus achieves the purposes and advantages indicated.
