The present invention relates to a device for easily tensioning cords attached between two anchor points.
In the present specification, including the appended claims, the term "cord" is intended to encompass threads and strings of any diameter, ropes of small, intermediate and large diameters, belts and the like.
2. Brief description of the prior art:
Everybody has already experienced the difficulty of tensioning a rope extending between two anchor points. Moreover, when one succeeds in installing the rope with the desired tension therein, the knots and/or mechanical fasteners used to attach the ends of the rope to the respective anchor points often loosen to reduce the tension in the cable. The rope itself may also lengthen under tension to further reduce the tension in the rope.
Also, it is often required to tension a rope already installed between two anchor points. In the prior art, such a tensioning operation has required detaching one end of the rope from the corresponding anchor point. Then, the above discussed situation is repeated.
Major difficulties are also met when it is required to interconnect end to end and tension two lengths of rope each having one end tied to a respective anchor point.
OBJECTS OF THE INVENTION
An object of the present invention is therefore to provide a device capable of tensioning a cord installed between two anchor points.
Another object of the present invention is to provide a cord tensioning device capable of both attaching end to end two lengths of cord and tensioning the resulting cord.
A further object of the invention is to provide a cord tensioning device that is easy to use and whose operation does not require physical strength.

More specifically, in accordance with the present invention, there is provided a cord tensioning device comprising:
a cord winding reel member to be mounted on a cord to be tensioned and to be rotated about an axis of rotation generally perpendicular to the cord for winding a section of that cord onto the reel member and thereby tension this cord; and a hook member connected to and extending transversely from the reel member for hooking the tensioned cord and thereby prevent the reel member and cord section to unwind.
Accordingly, the cord is tensioned by winding a section thereof on the reel member and that tension is maintained by hooking the hook member to the tensioned cord.
According to a preferred embodiment of the cord tensioning device, the reel member comprises first and second laterally spaced apart and generally parallel elongate elements on which the section of cord is wound, and the spacing between these first and second elongate elements define an aperture through which the cord is inserted prior to winding of a section thereof.
Accordingto anotherpreferredembodiment, the cord tensioning device includes two hook members comprising respectively a third elongate element extending radially from one end of the first elongate element and having a free end curved to hook the tensioned cord, and a fourth elongate element extending radially from one end of the second elongate element and having a free end curved to hook the tensioned cord. Preferably, the third and fourth elongate elements are radial and diametrically opposed.
The third and fourth elongate elements may comprise handle means for facilitating manual rotation of the reel member for winding the cord section and for subsequently hooking the hook members to the tensioned cord.
lS
When the cord to be tensioned is formed of two lengths of cord to be attached end to end and tensioned, the respective adjacent ends of the cord lengths are inserted in the spacing between the first and second laterally spaced apart and generally parallel elongate elements before winding a section of the resulting cord.
The objects, advantages and other features of the present invention will become more apparent upon reading of the following non restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures 1 and 2 of the appended drawings, a first embodiment 10 of the cord tensioning device according to the invention is illustrated.
The device 10 comprises a metallic rod 11 and a circular metallic plate member 12. The plate 30member 12 is welded at 13 to a central section 14 of the rod 11. At a first end of central section 14, the metallic rod 11 is bent at 90 (see 15) to form a first elongate element 16 generally perpendicular to 21~781S
the plate member 12. In the same manner, at the second end of the central section 14, the metallic rod 11 is bent at 90 (see 17) to form a second elongate element 18 laterally spaced apart and generally parallel to elongate element 16. As it will be described in the following description, the laterally spaced apart and generally parallel elongate elements 16 and 18 form a reel member 20 rotatable about an axis of rotation 19 to wind a section of cord to be tensioned.
At their end opposite to the plate member 12, the elongate elements 16 and 18 are respectively bent at 90 (see 21 and 22) to form third 23 and fourth 24 radial and diametrically opposed elongate elements. The free end 25 of elongate element 23 is curved in a direction comprising axial and circumferential components to form a first hook member for hooking the tensioned cord and thereby prevent the reel member 20 and cord section to unwind. In the same manner, the free end 26 of elongate element 24 is curved in a direction comprising axial and circumferential components to form a second hook member for hooking the tensioned cord and thereby contribute to prevent the reel member 20 and cord section to unwind. As can be seen in Figures 1 and 2, the circumferential components of the directions of curvature of the free ends 25 and 26 are opposite.
The second embodiment 30 of Figures 3 and 4 comprises the same circular plate member 12, the same elongate elements 16, 18, 23 and 24, and the same curved free ends 25 and 26 as the first embodiment of 21~781~
.
Figures 1 and 2. However, the cord tensioning device 30 of Figures 3 and 4 further comprises two asymmetric inverted V-shaped handles 27 and 28 to facilitate manual rotation of the reel member 20 about the axis 19 and for subsequently hooking the curved free ends 25 and 26 to the tensioned cord.
Referring to Figures 5 and 6, the third embodiment 40 of the cord tensioning device according to the invention comprises a metallic rod 29 and a circular metallic plate member 31. The plate member 31 is welded at 32 to a central section 33 of the rod 29. At a first end of central section 33, the metallic rod 29 is bent at 90 (see 34) to form a first elongate element 35 generally perpendicular to the plate member 31. In the same manner, at the second end of the central section 33, the metallic rod 29 is bent at 90 (see 36) to form a second elongate element 37 laterally spaced apart and generally parallel to elongate element 35. As it will be described in the following description, the laterally spaced apart and generally parallel elongate elements 35 and 37 form a reel member 38 rotatable about the axis of rotation 19 to wind a section of cord to be tensioned.
At their end opposite to the plate member 31, the elongate elements 35 and 37 are respectively bent at 90 (see 39 and 41) to form third 42 and fourth 43 radial and diametrically opposed elongate elements. The free end 44 of elongate element 42 is curved in a plane perpendicular to the axis 19 to form a first hook member for hooking the tensioned cord and 214781~
thereby prevent the reel member 38 and cord section to unwind. In the same manner, the free end 45 of the elongate element 43 is curved in the same plane as free end 44 but in an opposite direction to form a second hook member for hooking the tensioned cord and thereby contribute to prevent the reel member 38 and cord section to unwind.
The third embodiment 40 of Figures 5 and 6 further comprises a first metallic ring member 46 welded to the elongate element 42 and a second metallic ring member 47 welded to the elongate element 43, ring members 46 and 47 lying in a common plane parallel to the axis of rotation 19. Ring members 46 and 47 form handles to facilitate manual rotation of the reel member 38 about the axis 19 and for subsequently hooking the curved free ends 44 and 45 to the tensioned cord.
The fourth embodiment 50 of Figures 7 and 8 comprises the same circular plate member 31 and the same elongate elements 35 and 37 as the third embodiment of Figures 5 and 6. However, the elongate elements 42 and 43 are longer and bent over 360 to form loops 48 and 49, respectively, defining handles to facilitate manual rotation of the reel member 38 about the axis 19 and for subsequently hooking the curved free ends 44 and 45 to the tensioned cord.
Also, the curved free ends 44 and 45 of the device of Figures 7 and 8 are longer than those of the device of Figures 6 and 7 to better hook the tensioned cord.
21~7815 In the embodiment 50, the loops 48 and 49 are welded at their base 59 and 61, respectively, to make the cord tensioning device more rigid.
The fifth embodiment 60 of Figures 9 and 10 is identical to the fourth embodiment of Figures 7 and 8 but is provided with an additional arm 51 curved as shown in Figures 9 and 10 and having a proximate end welded inside the loop 48 at the level of the elongate element 42 and a distal end defining a hook 62. The curved free end (forming a hook) 44 have a first angular position about the axis of rotation 19 for hooking the tensioned cord after the reel member has rotated over a first angle (at least one half of a turn) while the hook 62 has a second angular position about the axis of rotation 19 for hooking the tensioned cord after the reel member 38 has rotated over a second angle smaller than the first angle.
When the cord to be tensioned is not sufficiently loose to allow the reel member 38 to rotate over 180 and enable the curved free ends 44 and 45 to hook the tensioned cord, the hook 62 can then be used to hook the cord and thereby prevent the reel member 38 to unwind. As hooking of the tensioned cord with the hook 62 requires a smaller angle of rotation about axis 19 in direction 52, the tension in the cord is smaller to prevent damage, in particular to a cord of small diameter.
Operation of the cord tensioning device in accordance with the present invention will now be described with reference to Figures lla-lld and 12a-12d, using the embodiment of Figures 5 and 6. It will 214781~
be apparent to those of ordinary skill in the art that the same explanations apply to the other embodiments illustrated in Figures 1-4 and 7-10.
To tension a cord 53 of which the two ends are attached to respective anchor points (not shown), the first step (Figure lla) consists of inserting the cord 53 in the aperture 54 defined by the spacing between the elongate elements 35 and 37. Of course, the cord 53 is inserted in the aperture 54 through the open end 55 of the reel member 38. As illustrated in Figure lla, the cord 53 is then generally perpendicular to the axis of rotation 19.
I5 The cord tensioning device 40 is then manipulated through the handles 46 and 47 to rotate the reel member 38 about the axis of rotation 19 (Figure llb) in direction 56 (Figure 6) to wind a section of cord 53 in order to tension that cord 53 (Figure llc). It is therefore important that the handles 46 and 47 be positioned on the side of the elongate elements 42 and 43 opposite to the elements 35 and 37 to prevent mutual interference of the handles and cord upon rotation of the device 40 about axis 19. The tensioned cord 53 is then hooked (Figure lld) to the curved free ends 44 and 45 to prevent the reel member 38 and accordingly the cord section to unwind. The cord 53 is then tensioned.
The example of Figures 12a-12d will demonstrate that the cord tensioning device according to the invention is capable of attaching end to end two lengths of cord while tensioning the cord formed by these two cord lengths.
Figures 12a-12d illustrate two lengths of cord 57 and 58 having respective opposite ends (not shown) attached to corresponding anchor points (not shown). The first step (Figure 12a) consists of inserting the adjacent ends 59 and 61 of the lengths of cord 57 and 58 in the aperture 54 defined by the spacing between the elongate elements 35 and 37. As illustrated in Figure 12a, the cord lengths 57 and 58 are then generally perpendicular to the axis of rotation 19.
The cord tensioning device 40 is then manipulated through the handles 46 and 47 to rotate the reel member 38 about the axis of rotation 19 in direction 56 (Figure 6) to wind a sections of the cord lengths 57 and 58 (Figures 12b and 12c) in order to tension the resulting cord. The tensioned cord lengths 57 and 58 are then hooked (Figure 12d) to the curved free ends 44 and 45, respectively, to prevent the reel member 38 and accordingly the wound cord section to unwind. The cord is then tensioned.
Cord tensioning devices in accordance with the present invention are advantageously made of steel, painted or anodized to resist to bad weather conditions.
Cord tensioning devices according to the invention can be used at home, at work and to do sports, for example to anchor planes, boats, tents, etc. and to secure goods on truck decks, etc.
Of course, any size of cord tensioning device can be manufactured to meet with the diameter of the cord and the requirements of each particular application.
As evidenced in the foregoing description, operation of the tensioning device in accordance with the present invention enables fast and secure tensioning, loosening, attaching and/or detaching of cords. Tensioned cords will not loosen without manual operation of the tensioning device. Also, the tensioning device will not wear, cut or otherwise damage the cords.
Although the present invention has been described hereinabove by way of preferred embodiments thereof, these embodiments can be modified at will, within the scope of the appended claims, without departing from the spirit and nature of the subject invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures 1 and 2 of the appended drawings, a first embodiment 10 of the cord tensioning device according to the invention is illustrated.
The device 10 comprises a metallic rod 11 and a circular metallic plate member 12. The plate 30member 12 is welded at 13 to a central section 14 of the rod 11. At a first end of central section 14, the metallic rod 11 is bent at 90 (see 15) to form a first elongate element 16 generally perpendicular to 21~781S
the plate member 12. In the same manner, at the second end of the central section 14, the metallic rod 11 is bent at 90 (see 17) to form a second elongate element 18 laterally spaced apart and generally parallel to elongate element 16. As it will be described in the following description, the laterally spaced apart and generally parallel elongate elements 16 and 18 form a reel member 20 rotatable about an axis of rotation 19 to wind a section of cord to be tensioned.
At their end opposite to the plate member 12, the elongate elements 16 and 18 are respectively bent at 90 (see 21 and 22) to form third 23 and fourth 24 radial and diametrically opposed elongate elements. The free end 25 of elongate element 23 is curved in a direction comprising axial and circumferential components to form a first hook member for hooking the tensioned cord and thereby prevent the reel member 20 and cord section to unwind. In the same manner, the free end 26 of elongate element 24 is curved in a direction comprising axial and circumferential components to form a second hook member for hooking the tensioned cord and thereby contribute to prevent the reel member 20 and cord section to unwind. As can be seen in Figures 1 and 2, the circumferential components of the directions of curvature of the free ends 25 and 26 are opposite.
The second embodiment 30 of Figures 3 and 4 comprises the same circular plate member 12, the same elongate elements 16, 18, 23 and 24, and the same curved free ends 25 and 26 as the first embodiment of 21~781~
.
Figures 1 and 2. However, the cord tensioning device 30 of Figures 3 and 4 further comprises two asymmetric inverted V-shaped handles 27 and 28 to facilitate manual rotation of the reel member 20 about the axis 19 and for subsequently hooking the curved free ends 25 and 26 to the tensioned cord.
Referring to Figures 5 and 6, the third embodiment 40 of the cord tensioning device according to the invention comprises a metallic rod 29 and a circular metallic plate member 31. The plate member 31 is welded at 32 to a central section 33 of the rod 29. At a first end of central section 33, the metallic rod 29 is bent at 90 (see 34) to form a first elongate element 35 generally perpendicular to the plate member 31. In the same manner, at the second end of the central section 33, the metallic rod 29 is bent at 90 (see 36) to form a second elongate element 37 laterally spaced apart and generally parallel to elongate element 35. As it will be described in the following description, the laterally spaced apart and generally parallel elongate elements 35 and 37 form a reel member 38 rotatable about the axis of rotation 19 to wind a section of cord to be tensioned.
At their end opposite to the plate member 31, the elongate elements 35 and 37 are respectively bent at 90 (see 39 and 41) to form third 42 and fourth 43 radial and diametrically opposed elongate elements. The free end 44 of elongate element 42 is curved in a plane perpendicular to the axis 19 to form a first hook member for hooking the tensioned cord and 214781~
thereby prevent the reel member 38 and cord section to unwind. In the same manner, the free end 45 of the elongate element 43 is curved in the same plane as free end 44 but in an opposite direction to form a second hook member for hooking the tensioned cord and thereby contribute to prevent the reel member 38 and cord section to unwind.
The third embodiment 40 of Figures 5 and 6 further comprises a first metallic ring member 46 welded to the elongate element 42 and a second metallic ring member 47 welded to the elongate element 43, ring members 46 and 47 lying in a common plane parallel to the axis of rotation 19. Ring members 46 and 47 form handles to facilitate manual rotation of the reel member 38 about the axis 19 and for subsequently hooking the curved free ends 44 and 45 to the tensioned cord.
The fourth embodiment 50 of Figures 7 and 8 comprises the same circular plate member 31 and the same elongate elements 35 and 37 as the third embodiment of Figures 5 and 6. However, the elongate elements 42 and 43 are longer and bent over 360 to form loops 48 and 49, respectively, defining handles to facilitate manual rotation of the reel member 38 about the axis 19 and for subsequently hooking the curved free ends 44 and 45 to the tensioned cord.
Also, the curved free ends 44 and 45 of the device of Figures 7 and 8 are longer than those of the device of Figures 6 and 7 to better hook the tensioned cord.
21~7815 In the embodiment 50, the loops 48 and 49 are welded at their base 59 and 61, respectively, to make the cord tensioning device more rigid.
The fifth embodiment 60 of Figures 9 and 10 is identical to the fourth embodiment of Figures 7 and 8 but is provided with an additional arm 51 curved as shown in Figures 9 and 10 and having a proximate end welded inside the loop 48 at the level of the elongate element 42 and a distal end defining a hook 62. The curved free end (forming a hook) 44 have a first angular position about the axis of rotation 19 for hooking the tensioned cord after the reel member has rotated over a first angle (at least one half of a turn) while the hook 62 has a second angular position about the axis of rotation 19 for hooking the tensioned cord after the reel member 38 has rotated over a second angle smaller than the first angle.
When the cord to be tensioned is not sufficiently loose to allow the reel member 38 to rotate over 180 and enable the curved free ends 44 and 45 to hook the tensioned cord, the hook 62 can then be used to hook the cord and thereby prevent the reel member 38 to unwind. As hooking of the tensioned cord with the hook 62 requires a smaller angle of rotation about axis 19 in direction 52, the tension in the cord is smaller to prevent damage, in particular to a cord of small diameter.
Operation of the cord tensioning device in accordance with the present invention will now be described with reference to Figures lla-lld and 12a-12d, using the embodiment of Figures 5 and 6. It will 214781~
be apparent to those of ordinary skill in the art that the same explanations apply to the other embodiments illustrated in Figures 1-4 and 7-10.
To tension a cord 53 of which the two ends are attached to respective anchor points (not shown), the first step (Figure lla) consists of inserting the cord 53 in the aperture 54 defined by the spacing between the elongate elements 35 and 37. Of course, the cord 53 is inserted in the aperture 54 through the open end 55 of the reel member 38. As illustrated in Figure lla, the cord 53 is then generally perpendicular to the axis of rotation 19.
I5 The cord tensioning device 40 is then manipulated through the handles 46 and 47 to rotate the reel member 38 about the axis of rotation 19 (Figure llb) in direction 56 (Figure 6) to wind a section of cord 53 in order to tension that cord 53 (Figure llc). It is therefore important that the handles 46 and 47 be positioned on the side of the elongate elements 42 and 43 opposite to the elements 35 and 37 to prevent mutual interference of the handles and cord upon rotation of the device 40 about axis 19. The tensioned cord 53 is then hooked (Figure lld) to the curved free ends 44 and 45 to prevent the reel member 38 and accordingly the cord section to unwind. The cord 53 is then tensioned.
The example of Figures 12a-12d will demonstrate that the cord tensioning device according to the invention is capable of attaching end to end two lengths of cord while tensioning the cord formed by these two cord lengths.
Figures 12a-12d illustrate two lengths of cord 57 and 58 having respective opposite ends (not shown) attached to corresponding anchor points (not shown). The first step (Figure 12a) consists of inserting the adjacent ends 59 and 61 of the lengths of cord 57 and 58 in the aperture 54 defined by the spacing between the elongate elements 35 and 37. As illustrated in Figure 12a, the cord lengths 57 and 58 are then generally perpendicular to the axis of rotation 19.
The cord tensioning device 40 is then manipulated through the handles 46 and 47 to rotate the reel member 38 about the axis of rotation 19 in direction 56 (Figure 6) to wind a sections of the cord lengths 57 and 58 (Figures 12b and 12c) in order to tension the resulting cord. The tensioned cord lengths 57 and 58 are then hooked (Figure 12d) to the curved free ends 44 and 45, respectively, to prevent the reel member 38 and accordingly the wound cord section to unwind. The cord is then tensioned.
Cord tensioning devices in accordance with the present invention are advantageously made of steel, painted or anodized to resist to bad weather conditions.
Cord tensioning devices according to the invention can be used at home, at work and to do sports, for example to anchor planes, boats, tents, etc. and to secure goods on truck decks, etc.
Of course, any size of cord tensioning device can be manufactured to meet with the diameter of the cord and the requirements of each particular application.
