Description:
AN ITEM CARRYING BRACKET FOR USE IN RETAINING AN ITEM ON A MOTOR VEHICLE

Technical Field

This disclosure relates in general to item carrying arrangements for vehicles.

Background to the Disclosure

Sometimes it is desirable to transport an item on the outside of a motor vehicle. The item may be too bulky to fit inside the vehicle, or it may be desired to use available storage space within the vehicle for other purposes. An item carrying arrangement can be used which is affixed to the vehicle and is adapted to hold or restrain the item.

In order to carry an elongate item, such as a shovel or other tool, it has been tried to use item carrying devices in the form of brackets. The brackets have a fixed jaw which is affixed to a vehicle, or a roof rack of a vehicle and a moveable jaw is hingedly attached to the fixed jaw. The item is held in the bracket by closing the jaws around the item. Usually, a pair of brackets is used at spaced apart locations along the vehicle or roof rack.

It has been tried to dampen the movement of the moveable jaw of these brackets by providing some type of friction to the movement of the jaw. It has been tried to apply friction by positioning one or more deformable washers between the jaws at the hinge joint and tightening a hinge pin at the hinge joint to create some preload force in the deformable washers to generate a frictional force which must be overcome to open or close the brackets. However, it has been found that the washers may wear quite quickly, and the preload force is lost, making the movement of the brackets loose.

There remains a need for improved item carrying arrangements for vehicles. Summary of the Disclosure

In a first aspect the present disclosure provides an item carrying bracket for use in retaining an item on a motor vehicle including: first and second bracket members; the bracket members are joined at a hinge and can rotate with respect to one another between a closed condition and an open condition; in the open condition an item to be carried may be introduced between the bracket members; in the closed condition the bracket members surround and retain the item; and the bracket includes a dampening mechanism which dampens the movement of the bracket members from the closed condition to the open condition; and wherein the resistance of the damping mechanism progressively increases as the bracket moves towards the open condition.

The dampening mechanism may include planar surfaces provided on the first or second hinge members, the planes of the surfaces may be angled with respect to the hinge axis; when in the closed condition the planes of the surfaces may be substantially parallel to one another, and as the bracket moves from the closed condition towards the open condition the surfaces may cause interference to dampen the movement of the bracket members.

The at least one compressible washer may be located between the surfaces.

The hinge may include a hinge pin, and the hinge pin may be tightened or loosened to adjust the amount of dampening applied to the movement of the bracket members.

Detailed Description of Embodiments

Referring to figures 1 and 2, an item carrying bracket 10 is shown for use in retaining an item on a motor vehicle. Bracket 10 includes a first bracket member in the form of moveable jaw 20 which is rotatably joined to fixed jaw 30 by way of hinge 40.

The jaws 20 and 30 can rotate with respect to one another between a closed condition shown in figure 1 and an open condition shown in figure 2 as indicated by arrow A in figure 2. The moveable jaw 20 rotates by 100 degrees to reach the open condition which is defined by a hard stop provided by the abutment of the two jaws in the region indicated by arrow B. When in the open condition, an item to be retained be introduced between the jaws 20, 30 and when in the closed condition, the jaws 20, 30 surround and support the item.

Referring to figures 3 and 4 hinge 40 includes a hinge pin in the form of a hinge bolt 42 which passes through jaw 20 and also through apertures provided in two upstanding ribs 36, 37 which are located inside jaw 30. Hinge bolt 42 has a threaded end region which is received inside nut 44. Two circular compressible washers 46, 47 are retained on the hinge bolt 42 in regions between the ribs 36, 37 and jaw 20. Bracket 10 includes a dampening mechanism which dampens the movement of the bracket members from the closed condition to the open condition which includes two opposed planar surfaces 28, 38 of the jaws face each other. The surfaces 28, 38 are planar in the region of the washer 47 and are angled with respect to the hinge axis. They are offset at an angle from a line orthogonal to the hinge axis by 2 degrees. The angular offset of the surfaces gives rise to compression of the washer 47 which creates the dampening effect of the dampening mechanism.

Referring now to figures 5A and 5B, the offset angles of the surfaces are illustrated in exaggerated form to better explain the operation of the concept of the dampening mechanism. In figure 5A, the bracket is in the closed condition. The surfaces 28, 38 are parallel to one another. In figure 5B, the bracket is in the open condition. The relative rotation of the surfaces 28, 38 in means they are no longer parallel to one another. They are now offset by about 2 degrees. This causes compression of the resilient washer 47 in the region indicated by the solid arrows in the figure. The compression of the washer causes friction between the surfaces 28, 38 and the washer. This creates a drag which dampens the movement of the bracket.

It can be seen that, as the hinge moves from the closed condition to the open condition the effective relative offset of the angles of the faces 28, 38 progressively increases. This has two effects. Firstly, this progressively increases the dampening force as the hinge moves towards the open condition. Secondly, the onset of the dampening force can be controlled to occur at a particular degree of angular opening of the jaw.

The angle of onset of the dampening force, and the amount of dampening force, is controlled by a user by adjusting the effective width of the hinge bolt 42. This is achieved by inserting an Allen key into the formation 46 in the end of the hinge bolt and rotating the bolt 42 with respect to the nut 44. Tightening the hinge bolt pinches the hinge assembly together, reducing the width of the space occupied by the compressible washers. This causes the frictional dampening force to be greater at a smaller degree of opening of the jaws. Also, the frictional force at the position of maximum jaw opening is increased.

Referring again to figure 1, bracket includes a latching mechanism. A spring- loaded detent inside jaw 20 engages with a formation in jaw 30 when the bracket is put into the closed condition. The detent of the latching mechanism is released by depressing button 22.

As best seen in figure 6, bracket 10 also includes a locking mechanism which includes a key operated lock barrel 24. The lock barrel can be put in into a locked condition to prevent the button 22 from being depressed to release the latching mechanism.

The jaws are formed from cast aluminium. The pin 54 and hinge pin 42 and nut 44 may be formed from steel.

Examples of item carrying arrangements incorporating brackets 10 will now be described with reference to stowing a hi lift jack on a vehicle. A hi lift jack is a piece of equipment used on offroad/overlanding/touring vehicles. Its purpose is a mechanical vehicle jack/lift. Being mechanical makes it a reliable component for agricultural use or offroad vehicle in remote areas. Its travel range compared to a traditional car jack/lift also is advantageous. The hi lift jack is a large item which is inconvenient to cany inside vehicles.

Referring again to figures 1 and 2, bracket 10 is fitted with a removable insert which is provided in two halves 50, 52. The two halves are push fitted into their respective jaws 20, 30. The insert is configured to make bracket 10 suitable for stowing a hi lift jack. The insert halves are formed from an elastomeric material and are shaped so that when in the closed condition the insert halves form a dog bone shaped aperture 57 which conforms around the leg of the jack, and a circular aperture 58 which confirms around the handle of the jack. A pin 54 is provided in insert half 50 which engages with one of a series of holes provided on the leg of the jack.

Referring to figures 6 and 7, two of brackets 10 are shown in a side mount configuration to retain a hi lift jack 110 in relation to a vehicle. The brackets 10 are attached to a roof rack 100 of the vehicle at spaced apart locations along the length of a side region of the roof rack 100.

In order to stow the hi lift jack the brackets 10 are moved by the user into their open conditions. The hi lift jack is then rested on the two jaws 20 of the brackets so that the pins 54 of the inserts (pin 54 best seen in figure 7) each engage with one of a series of holes 112 provided along the length of the jack 110. The handle of the jack lies in the half circular recess 56 of insert half 50. The moveable jaws 20 are then lifted using one hand under each jaw 20 to rotate the jaws and jack 110 in unison to close the brackets 10 by engaging the latches of the brackets to arrive at the configuration shown in figure 8. The elastomeric material of the insert becomes slightly compressed in the regions of the apertures 57, 58 around the leg and handle of the jack to snugly clamp around the jack to retain the jack in place. The hi lift jack is now retained for carrying on the vehicle. The brackets 10 can optionally be locked to prevent unauthorised removal of the jack.

In order to release the jack, the latch buttons 22 of the brackets are depressed to release their respective latching mechanisms and the jaws 20 are pulled open in a downwards direction. The brackets 10 open against the damping action of the compressible washers. This slows the opening movement of the brackets which would otherwise open quite suddenly under the weight of jack 110 which can weigh of the order of 14-16kg. Opening the brackets without dampening would otherwise present a hazard/danger to the user or vehicle when opened. In addition, when the bracket is near to the fully open position, the dampening action prevents jaw 20 from contacting the hard stops with high impact. With the brackets open, the jack 110 can be removed. The brackets 10 may then be returned to their closed conditions.

As explained above, the amount of friction force and the opening angle at which dampening is applied can be adjusted by adjusting the hinge pin. Therefore, the brackets can be adjusted to suit jacks which are lighter or heavier, or can be adjusted to be used with other accessories of different weights. The hinge pin can also be adjusted to increase the friction force to compensate for wear in the compressible washers over time.

Referring now to figures 10 and 11, use of the brackets in a top mount configuration is shown. This arrangement differs from the arrangement of figures 6 to 8 in that the fixed lower jaw 30 is mounted in a horizontal, rather than a vertical, orientation. Also, the insert halves 50, 52 are swapped over within the jaws so that the pin 54 is located in the fixed jaw 30. In this configuration, in order to stow the jack, the brackets 10 are firstly put into their open configurations. The brackets are opened in an upwards direction by raising both of the moveable jaws in turn by hand against the dampening action of the brackets. The dampening action retains the moveable jaw 20 of the bracket in the open condition. This allows a user to have both hands free to lift the jack up and rest it on the two fixed jaws 30 to engage the jack with the pins 54. The moveable jaws 20 may then be closed by rotating them in a downwards direction to their latching positions. Removal of the jack 110 is achieved by reversing this procedure.

The dampening action therefore provides both a safety feature to prevent sudden opening of the bracket as well as improving ease of use in providing a smooth opening action and holding the brackets open when in a top mount configuration.

The bracket 10 may be reconfigured for use with other types of items by using a different insert in the bracket. Referring to figure 11, an alternative insert is shown in the bracket formed from halves 150 and 151. The insert is formed from resilient elastomeric material and is shaped to provide a diamond shaped aperture 152. This insert can be used for stowing differently shaped items such as shovels, rods or other items.

It can be seen that embodiments have at least one of the following advantages:

• The dampening action provides a controlled opening operation of the bracket in a downward direction when the bracket is retaining a heavy item improving safety of operation.

• The progressive dampening action can prevent the hinge hitting its fully open stops in a sudden manner, improving comfort of operation.

• The dampening action allows the moveable jaws of the brackets to be held open when used in an upwardly opening direction. This allows both hands to be used to lift the item to be retained into the brackets.

• The progressive increase in the dampening force generated by the angular offset surfaces is not immediately lost if the resilient washers wear over time. Instead, the angle of the onset of the friction force changes.

• Replaceable inserts allow brackets to be used to retain a variety of differently shaped items.
