DESCRIPTION OF EMBODIMENTS

[0019] Referring to the drawings and first to FIGS. 1 and 2, there is shown a first wrench holder 10 for holding and carrying a set of wrenches. The wrench holder 10 includes a frame 12 and a coil spring 14. The frame 12 is a generally loop-shaped quadrilateral in this example and includes four sides 16, 18, 20 and 22. The spring 14 is coiled about one of the sides of the frame 12 which in this example is the side 22. The spring 14 in this example is generally cylindrical with a plurality of spaced-apart coils, for example, adjacent coils 15a, 15b, 15c and 15d. The coils 15a, 15b, 15c and 15d in this example are similar in size to each other and are evenly spaced-apart from one another. However, the coils 15a, 15b, 15c and 15d of the spring 14 may abut each other in other examples. The sides 16, 18, 20 and 22 of the frame 12 are substantially straight in this example and are joined by rounded corner portions 17, 19 and 21. The frame 12 may be formed from a single piece of suitable material such as metal or plastic. The frame 12 is tapered in this example such that the sides 18 and 22 slope between the sides 16 and 20. The sides 18 and 22 accordingly extend between the sides 16 and 20 in non-parallel relation to each other and converge towards the side 20. The side 16 has a length which is greater than that of the side 20 in this example.

[0020] As best shown in FIG. 2, there may be a space 24 in the side 22 of the frame 12 which results in the frame having spaced-apart end portions 26 and 28 of the sides 16 and 22, respectively. The frame 12 is tubular in this example and has a hollow cross-section which allows the end portion 26 to receive a first end 30 of the spring 14. The first end 30 of the spring 14 is press fitted into the side 16 of the frame 12 to restrict movement of the first end 30 of the spring 14 relative to the end portion 26 of the frame 12. A second end 32 of the spring 14, which is best shown in FIG. 1, is hook-like and engages the end portion 28 of the frame 12. The second end 32 of the spring 14 translates or moves axially along the side 22 of the frame 12 as the spring 14 stretches and compresses. The first end 30 of the spring 14 remains substantially stationary relative to the frame 12 and, in particular, to the side 16 of the frame 12, as the second end 32 of the spring 14 moves axially along the side 22 of the frame 12.

[0021] Referring now to FIG. 3, the wrench holder 10 is shown holding a set of wrenches 34 which includes wrenches 36a, 36b and 36c. Handles of the wrenches are inserted between the adjacent coils 15a, 15b, 15c and 15d of the spring 14 as shown for respective handles 38a, 38b and 38c of the wrenches 36a, 36b and 36c. Respective open jaws 40a, 40b and 40c of the wrenches 36a, 36b and 36c are also fitted over the side 18 of the frame 12 as best shown in FIG. 4. The restoring force of the spring 14, i.e. the force exerted when the spring is stretched and which brings the spring back towards its equilibrium length, holds the wrenches 36a, 36b and 36c in position when their respective handles 38a, 38b and 38c are inserted between the coils 15a, 15b, 15c and 15d of the spring 14. Furthermore, the side 18 of the frame 12 is received by and engages the open jaws 40a, 40b and 40c of the wrenches 36a, 36b and 36c to restrict outward rotation of the wrenches 36a, 36b and 36c relative to the wrench holder 10 when their respective handles 38a, 38b and 38c are inserted between the coils 15a, 15b, 15c and 15d of the spring 14. In particular, the side 18 limits the degree of permissible rotation of the wrenches relative to a longitudinal axis 100 of the frame 12 once the wrenches are inserted between the coils of the spring 14. The spring 14 and the side 18 of the frame 12 accordingly work in combination to securely hold the wrenches.

[0022] The resilience of the spring 14 allows the spring to stretch to accommodate wrenches of different thicknesses. The restoring force of the spring 14 means that wrenches having handles of varying thicknesses are still securely retained between its coils 15a, 15b, 15c and 15d. However, even when the spring 14 is at its equilibrium length, the coils 15a, 15b, 15c and 15d of the spring 14 are spaced-apart at a distance that allows wrenches having thinner handles to still be sufficiently retained between the coils 15a, 15b, 15c and 15d.

[0023] The restoring force of the spring 14 also means that wrenches are securely retained between its coils 15a, 15b, 15c and 15d when any number of wrenches between the maximum and the minimum number of wrenches capable of being retained by the spring 14 is inserted between the coils 15a, 15b, 15c and 15d of the spring 14. The wrench holder 10 can therefore hold as many or as few wrenches as needed by a user.

[0024] Since the wrenches only engage the frame 12 at their respective open jaws, the wrench holder 10 can also accommodate wrenches of different lengths. The handles of the wrenches extend outwardly beyond the spring 14. Since the side 16 of the frame 12 is longer than the opposite side 20 in this example, the distance between the sides 18 and 22 is greater near the side 16 and decreases towards the side 20. Wrenches having shorter handles can therefore be inserted between the coils 15a, 15b, 15c and 15d of the spring 14 near the side 20 of the frame 12 where the distance between the sides 18 and 22 is smaller. This allows the open jaws of shorter wrenches to engage the side 18 of the frame 12 while the handles of the wrenches are retained between the coils 15a, 15b, 15c and 15d of the spring 14. Conversely, wrenches having longer handles can be inserted between the coils 15a, 15b, 15c and 15d of the spring 14 near the side 16 of the frame 12 where the distance between the sides 18 and 22 is greater.

[0025] The wrench holder 10 may include a strap 42, best shown in FIG. 3, for releasably attaching the wrench holder to, for example, a belt of a user to allow the user to carry and easily access the wrenches retained by the wrench holder during use. The wrench holder 10 may also be used in conjunction with a tool box to organize wrenches within the tool box. The wrench holder 10 may be transported in the tool box between locations and/or stored in the tool box when not in use. The wrench holder 10 may be colour-coded to further facilitate organization and ease of use of the wrenches. For example, a first one of the wrench holders may be used to hold wrenches of metric sizes and may be coded one colour, such as blue, and a second one of the wrench holders may be used to hold wrenches of imperial sizes and may be coded another colour, such as red. This allows a user to readily identify and select the desired measurement size of wrenches.

[0026] The order of the wrenches held in the wrench holder 10 shown in FIGS. 3 and 4 is intended to be an example only. It will be understood by a person skilled in the art that the wrenches can be inserted into the wrench holder 10 in different ways to arrange the wrenches in different orders.

[0027] Referring now to FIGS. 5 and 6, there is shown a wrench holder 210 for holding and carrying a set of wrenches. Like parts have like numbers and functions as the wrench holder 10 described above and shown in FIGS. 1 to 4 except in the 200 series. The wrench holder 210 is substantially the same as the wrench holder 10 described above and shown in FIGS. 1 to 4 with the exception that there is no space in the side 222 of the frame 212. The sides 216 and 222 of the frame 212 are joined by a corner portion 223 which is sharp in this example but may be rounded in other examples. A first end 250 of the spring 214 is hook-like and engages the side 222 of the frame 212 proximal to the side 216. The first end 250 of the spring 214 is secured to the side 222 of the frame 212 adjacent to the corner portion 223, for example, by being crimped onto the side 222. The second end 232 of the spring 214 is also hook-like and engages the side 222 of the frame 212 proximal to the corner portion 221. However, the second end 232 of the spring 214 translates or moves axially along the side 222 of the frame 212 as the spring 214 stretches and compresses to accommodate wrenches inserted between its coils. In contrast, the first end 250 of the spring 214 remains substantially stationary relative to the frame 212 and, in particular, to the side 216 of the frame 212, as the second end 232 of the spring 214 moves axially along the side 222 of the frame 212.

[0028] Referring now to FIGS. 7 and 8, there is shown a third wrench holder 310 for holding and carrying a set of wrenches. Like parts have like numbers and functions as the wrench holder 10 described above and shown in FIGS. 1 to 4 except in the 300 series. In this example, the wrench holder 310 comprises a frame 312 and a coil spring 314 which are unitary and are formed from a single member 313. The member 313 is a single length of metal wire in this example. An end coil 360 of the member 313 straightens and extends outwardly to form a first side 316 of the frame 312. The frame 312 is bent at corner portions 317, 319 and 321 to form the remaining sides 318, 320 and 322. The corner portions 317, 319 and 321 are rounded in this example while the sides 316, 318, 320 and 322 are substantially straight in this example. Accordingly, in this example, the frame 312 is a generally loop-shaped quadrilateral. The side 322 of the frame 312 extends through an interior space 362 of the spring 314 and an end portion 364 of the frame 312 is secured to the spring 314 adjacent to the end coil 360. The end portion 364 of the frame 312 may be crimped onto the end coil 360 to secure the end portion 364 to the spring 314.

[0029] A free end 332 of the spring 314 is hook-like and engages the side 322 of the frame 312. The end 332 of the spring 314 translates or moves axially along the side 322 of the frame 312 as the spring 314 stretches and compresses to accommodate wrenches inserted between its coils. Since the end coil 360 is integral with the side 316 of the frame 212 in this example, the end coil 360 remains substantially stationary relative to the frame 212 as the end 332 of the spring 314 moves axially along the side 322 of the frame 312.

[0030] It will be further understood by a person skilled in the art that many of the details provided above are by way of example only, and are not intended to limit the scope of the invention which is to be determined with reference to the following claims.
