Abstract

The invention concerns a device for winding up a strap, for example a tightening strap. It comprises an elongate member (1) which at one end forms a handle (2) and which at its opposite end has a guide device for the strap (6) which is to be wound up. Approximately at its middle the member (1) has a crank (7) with an attachment device for the strap (6). The guide device may advantageously consist of two parallel guide pins (4, 5) extending at substantially right angles from said member (1), and the attachment device for the strap (6) can consist of two mutually parallel crank pins (8, 9) which are connected to the crank (7).

Description

A DEVICE FOR WINDING UP A STRAP
The present invention refers to a device for winding up a strap.
In conveying goods on a truck it is customary to secure the goods with tightening straps which are fastened to hooks on each side of the platform of the truck and thereafter are tightened by a strap
tightening device. The strap tightening devices are usually lever structures, and a plurality of known types exist.
The tightening straps generally consist of two parts, one of which is a fairly long strap whereas the other one is a considerably shorter strap. The strap tightening devices can consist of two parts which are fastened one at each end of the long and short
tightening strap parts, respectively, and which may be interconnected for tightening the two parts of the tightening straps. The free ends of the tightening straps are fastened to the platform of the truck in the mentioned manner by means of a hook.
After the conveyance has been completed, the tightening straps are retained until the next occasion of use. The short tightening strap part does not cause any difficulties in this regard because it can easily be wound up. Contrary thereto, the long tightening strap part can cause difficulties, for example if the tightening strap has been used in unfavorable weather conditions, such as in snow and/or ice, in addition whereto sand and gravel may have become attached to the strap. In such case it becomes unpleasant to nandle the strap to roll it up, which furthermore may be difficult if the strap is partly frozen stiff.
The present invention has the object of
providing a device by means of which a tightening strap can be rolled together in simple manner and without it being unpleasant to handle the strap so that the strap is ready to be used again on the next occasion of use. The means by which this is achieved are disclosed in the accompanying claims.
The invention will be described more
specifically in the following with reference to the accompanying drawings, in which Figure 1 shows a perspective view of a strap winding device in
accordance with the invention viewed from one side, Figure 2 shows a perspective view of the strap winding device in accordance with the invention viewed from the other side, Figure 3 shows a side view of part of the strap winding device in accordance with the invention, Figure 4 shows an alternative embodiment of the strap winding device in accordance with the invention produced in aluminum by means of extrusion technology, Figure 5 illustrates the possibility of producing the alternative embodiment in accordance with Figure 4 in two parts, which may be appropriate from the manufacturing viewpoint, Figure 6 shows the two parts which are illustrated in Figure 5 taken apart, and Figure 7 shows part of the embodiment in accordance with Claim 5 on a larger scale to
illustrate interconnecting the two parts of the embodiment. The same reference designations have been used in the various figures wherever possible.
The strap winder in accordance with the
invention consists of an elongate member 1 , for example of a metal plate, such as is shown in Figure 1 , or for instance in the shape of a tube. One end 2 of the plate forms a handle and may for instance be provided with a rubber covering 3 so that it is pleasant to hold the handle 2 even in winter
conditions. At the opposite end of the handle 2, the plate 1 is provided with two parallel guide pins 4 and 5 having approximately the same lengths as the width of the strap (6 in Figure 3) which is to be wound up. Guide pins 4 and 5 are disposed at a mutual distance which is slightly greater than the thickness of strap 6. They may be embodied in different ways, for example as stationary pins or as rotatable pins. If desired the pins can be provided with a friction reducing material located on the surface, such as teflon. They can also be embodied with individual rotative sheaths on the outside of a stationary pin. The intention is that they are to serve as guides for the strap when winding up the latter. In order that strap 6 shall not fasten to the end 14 of plate 1 said end is slightly bent.
For convenient handling the member or plate 1 in the embodiment illustrated in Figures 1-3 forms an angle approximately at its middle and thus comprises two portions lying in the same plane, but
alternatively the member can be completely straight.
Approximately at the middle of plate 1 in the lengthwise direction thereof a crank 7 with a handle 13 is positioned on the opposite side as compared to the above-mentioned guide pins. Crank 7 is mounted in plate 1 , and on the opposite side of the plate to the crank two parallel crank pins 8 and 9 are secured to a disc 10 which is fastened to the shaft (not shown) of crank 7 and which therefore rotates when the crank is turned so as to carry along crank pins 8 and 9 in the rotational movements. In the illustrated case the crank pins are flat and oblique with an appropriate slant so that, as is illustrated in Figure 3, one end of a strap 6 can be placed between them and will begin to be wound up when the crank is turned. For
convenient attachment the crank device may be embodied such that when the crank depends straight downwards the crank pins are vertical. Between crank 7 and plate 1 and between disc 10 and plate 1 plastic washers 11 and 12, respectively, are disposed in the relevant case so that cranking can be readily performed. The drawing shows two crank pins, but it should be pointed out that a plurality thereof can exist, for example three or four. It would also be possible to have a slit larger or smaller cylinder or some other
configuration to secure the strap end instead of the illustrated crank pins.
The mode of operation of the strap winder should be obvious from the description given above, namely that strap 6 is introduced between guide pins 4 and 5 at the free end of plate 1 and the other end of strap 6 is simultaneously placed between the two flattened crank pins 8 and 9 (they can also be circular or have an arbitary profile) and the handle of the windup plate is held while cranking so that strap 6 will be wound up on crank pins 8 and 9. In this manner it is not necessary to touch the strap other than when placing it between the crank pins in the beginning of the operational phase, and thus one avoids handling the strap when it is wet or icy or sandy, etc.
The embodiment shown in Figure 4 illustrates another structure of the body of the subject of invention which is produced of aluminum by means of extrusion technology. The body has a handle 15 at one end, the crank shaft is intended to be introduced into the hole 16, and the guide pins are intended to be introduced into the holes 17 and 18.
From the viewpoint of manufacture it may be appropriate to divide the body into two parts as is indicated in Figure 1, wherein one part is designated 19 and the other is designated 20. The two parts are shown separated from each other in Figure 6. An example of connecting the two parts 19 and 20 together is illustrated in detail in Figure 7. The intention is that a looking pin is to be urged into hole 22.
The invention is not restricted to the
embodiments described above and shown in the drawings, and a substantial number of modifications can be made within the scope of the invention. Thus, for example the above-mentioned flattened crank pins may be completely round, oval or of arbitrary shape.
Furthermore, the member 1 can consist of other
material than metal, for example plastic or wood, and in addition the guide pins can be oval or can have an arbitrary other shape. Therefore, the illustrated embodiments only show an example of the invention and its mode of utilisation. A plurality of other areas of use can also be contemplated.
