Abstract
The invention relates to a winder device and in particular a winder device for winding straps, rope, cable and similar materials; the winder device comprising a rotatable spool that in use receives the strap for winding, the spool being rotatable by a winder means.
Description
Winding device
Field of the Invention
The invention relates to a winder device and in particular a winder device for use for
winding straps, rope, cable, and similar materials.
Background
Many applications use a strap, rope, cable, and other similar material as a means of
securement or tensioning. Generally the material is re-useable. Once used the securement
material is generally wound up for storage, though more often than not this is not the case
in practice as this process frustrates many operators.
The most common method of winding up such securement materials is by hand. However
there are also a number of winding devices available but these appear to have limited use
due to limitations specific to each device.
Common winding devices wind straps (and similar materials) onto a spool like structure
and may also be used to house the strap whilst not in use. Typically one end of the strap
may be anchored to a fixed point within the spool like structure prior to winding.
Alternatively, one end of the strap may be fixed to an anchor point to enable the strap to
be tensioned during winding.
In the case of a truck, the winder may typically be anchored to the deck or gunnel. The
unanchored end of the strap is fed through the winder’s spool and tensioned until it is held
reasonably taut so winding can begin. Thus it can be difficult and time consuming to wind
a length of strap using many of the devices currently available.
Alternatively the winder device may be fixed to some other platform or hand held. Often
when the strap is removed from such devices there is insufficient room at the centre of the
wound up material to tie off as is traditional in many industries, for example the trucking
industry.

DETAILED DESCRIPTION
Referring to the figures, there is illustrated a reusable winder device according to the
invention, indicated generally by the reference numeral 1. The winder device 1 is suitable
for use in winding a strap 23.
The strap 23 could be any type of strap, strop, rope or other flexible elongate member that
is suitable for supporting the load or similar tensioning situation. The strap 23 will
typically, although not always, have a widthwise dimension that is larger than its depth
dimension.
The winder device 1 comprises a spool 6, winder drive arm 3, and drive pawl 17.
A spool 6 is fixed to one end of the winder drive arm 3 via an aperture 8 in the spool 6.
3447305-2
As shown in Figure 3 the aperture 8 may typically, though not always, be countersunk in
order that the top of the fixing 13 is flush with the surface 12 of the spool 6. A washer 23
may be used to assist the fixing 13.
As shown in Figure 2 the spool 6 is rotatable relative to the winder drive arm 3 about a
rotation axis RA. The spool 6 has angled gears16 that are suitable for driving by a drive
pawl 17 in one direction, but which enable the drive pawl to pass over the gears in the
opposite direction.
As shown in Figure 5, the outer surface 2 of the spool 6 will typically, though not always,
have a frustoconical shape having a slight taper in favour of the outside of the spool 6 and
having a smooth external finish to assist in removal of the strap from the spool of the
winder device 1.
A slot 5a 5b is for receipt of part of a strap 23 to be wound, as will be described below.
The spool 6 may also contain a lip 14 which assists the operator with aligning the strap 23
when initiating operation of the winder device 1.
With reference to Figure 4, a winder drive arm 3 contains a transverse member 4
connecting the handle 11 and the plate 21 (as best seen in Figure 5).
The handle 11 has four sides 9a, 9b, 9c, 9d. The sides of the handle 11 may be open 9a or
closed 9b in nature. Likewise within the handle 9 may be solid, hollow, or a combination.
The handle 11 may also contain support structures 22 when the handle 11 is not solid.
At the top of the handle 11 is an eyelet 10 capable of housing a clip or similar connection
means used for carrying or storage of the winder device 1.
As can be seen from Figure 7, the winder device 1 contains a drive pawl 17. The drive pawl
17 contains ratcheting tines 18 such that when the winding device 1 is in operation, the
tines engage with the spool gears 16 so as to rotate the spool 6 in a clockwise direction
3447305-2
rotatable relative to the winder drive arm 3. In this embodiment the drive pawl 17 contains
a square shaped aperture 19.
Figure 8 shows a protruding square section 20 on the underside of the drive wind arm 3
which houses the drive pawl 17 via the drive pawl aperture 19.
Figure 10 shows the drive pawl 17 housed against the underside of the winder drive arm 3.
The winder device 1 will now be described in use.
The winder device 1 is generally hand operated. The operator begins by inserting part of
the strap 23 into slots 5a or 5b as can be seen in Figure 11, then with the assistance of the
operator’s hand, aligns the strap 23 so it is flush with the lip 14 on the spool 6.
With the operator’s other hand, the operator initiates winding of the strap 23 by rotating
the winder drive arm 3 back and forth such that it allows the ratcheting tines 18 to engage
with the spool gears16 when the winder drive arm 3 is moved in a clockwise direction, and
as such moving the spool 6 in a clockwise direction allowing the winder device 1 to wind
additional strap 23 around the spool 6.
Figure 12 shows the strap 23 wound on to the spool 6.
Once winding is complete the operator can remove the strap 23 from the winder device 1
by sliding it away from the spool lip 14 along the frustoconical surface 2.
Once removed from the winder device 1, the wound strap 23 has an internal aperture the
same size as the diameter of the spool 6 which can be used by the operator to tie off the
strap 23 by threading an end section of the strap 23 through the aperture and back over the
wound strap 23.
The above describes preferred embodiments of the present invention, and modifications
can be made thereto without departing from the scope of the invention.
3447305-2
For example, in an alternative configuration the winder drive arm 3 may be replaced with
an electric drill having an attachment which inserts into an aperture in the centre on the top
of the spool 15, therefore replacing the hand ratcheting function of the winder device.
In another example the drive pawl 17 may be inserted onto the underside of the spool 6 in
such a way that the ratcheting tines 18 are engaged with the spool gears 6 in an anti-
clockwise direction.
In another example the spool 6 is fixed to the winder drive arm 3 via a grooved slot
without the need for fixings 13.
