Description
~284971 SUPPORT FOR A SPARE WHEEL OF A MOTOR VEHICLE
BACKGROUND OF THE INVENTION
This invention relates to a support device for the spare wheel of a motor vehicle and particularlY but not exclusively for a motor vehicle of the type having a tail gate which can pivot about a horizontal axis to be raised and lowexed for cargo access.
Various designs of device for this purpose have been provided, for example, in U.S. Patents 4,312,620;
4,483,468; 3,362,597; 2,819,004; 3,387,754; 3,610,658.
In addition, some designs have been put on the market and have been shown in various magazines.
However, generally, these designs require modi-fications to the basic vehicle including drilling holes in body parts, cutting parts of a bumper away and mount-ing a device, for example, on the bumper.
Various recent designs of a vehicle are avail-able and often these include a support for a license plate which is positioned centrally of the bumper and slightly below the bumper which is also the location of a towing bracket which forms part of the vehicle.
It is highly undesirable in any eguipment mounted on a vehicle after manufacture that any holes be drilled in the vehicle or the modifications made since ' :, ~
.~. ~ , .
:
~284971 these modifications will form the basis for corrosion and may cause distortion or other damage to the vehlcle.
It is also highly desirable that a device of this type provides a highly attractive appearance so as not to detract from the design of the original vehicle, particularly bearing in mind the high cost of vehicles in the current market conditions.
Current vehicles such as the GMC Jimmy Range and similar vehicles such as the Blazer and Bronco have an area set aside inside the rear of the vehicle for receiving a spare wheel. However, this spare wheel can significantly reduce the cargo area since the spare wheel is mounted on top of the flat floor plate which defines the rear of the vehicle and in many cases defines the flat area with the folded down rear seats. Many users, therefore, often prefer to carry the spare wheel outside the vehicle on the roof, attached to the front or attach-ed to a specially provided carrier at the rear of the vehicle. None of the devices currently available is entirely satisfactory since they do not provide the required attractive appearance and in many case can cause damage to the vehicle structure when attached as a retro-fit.

SUMMARY OF THE INVENTION
It is one object of the invention, therefore, to provide an improved attachment device for mounting the spare wheel of a vehicle rearwardly of the vehicle.
According to a first aspect of the invention, therefore, there is provided a support device for a spare wheel of a motor vehicle comprising a box member includ-ing two upstanding sides a transverse top, a transverse bottom, a hingedly mounted front cover movable from an open position exposing an interior of the box member to a closed position covering the box member and defining a front face thereof, a latch portion extending upwardly from the box member, a support member having a pair of sides each pivotally mounted on a respective side of the box member so as to be movable substantially through 90 from a lowered position to a raised support position, said support member defining a cradle portion and an upstanding plate portion with the cradle having side members each arranged adjacent respective one of the sides of the box member and arranged such that said upstanding portion and cradle portion can receive and support a spare wheel and tire of the vehicle and a vertically slidable latch mounted on said upstanding portion and slidable to a position engaging a side of said latch portion to retain said support member in said 12~4971 raised position.
According to a second aspect of the invention, there is provided in a motor vehicle including a rear bumper, a bracket mounted on the vehicle beneath said rear bumper, an improvement comprising a carrier for a spare wheel for the motor vehicle comprising an attach-ment member mounted on said bracket beneath said bumper, a support member having a cradle and an upwardly project-ing attachment portion mounted on said support member for pivotal movement about a horizontal axis from a lowered position to an upright raised position, said support member being shaped to extend from said attachment member upwardly around and over said bumper and including a latch portion movable from a raised position vertically downwardly behind said bumper to engage said attachment member.
The device has the advantage, therefore, that it provides a box device which can be mounted upon the tow bar underneath the bumper with a locking front cover which allows only the user to access the attachment bolts to prevent theft. The device can be readily pivoted on the attachment box with sides mounted on pivot pins projecting outwardly from the sides of the box. The support which carries the wheel includes sides which ..
:- ~ ' .' P2~34971 include a cut-out extending around the bumper and project to a position slightly forwardly of the bumper, that is between the bumper and the vehicle so that a latch member can extend into that position and latch against the attachment box so the whole unit is held on the frame of the vehicle and is separated from the bumper to prevent any vibration or damage to the bumper.
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the best mode known to the applicant and of the preferred typical embodiment of the principles of the present invention, in which:

DETAILED DESCRIPTION
In Figure 1 there is shown the rear of a motor vehicle generally indicated at 10 which includes a tail gate 11 of the type which can be pivoted about a horizon-tal axis at a lower edge of the tail gate so as to be raised and lowered for cargo access. Furthermore, the rear of the vehicle includes a conventional bumper 12 formed of a folded sheet metal material and in the parti-cular style of vehicle concerned, that is GMC Jimmy, there is a central recessed portion 13 of the bumper at which the bumper is reduced approximately to one-half of its depth at a portion of the order of 15 inches wide at the central section.
Beneath the bumper is provided a frame member 14 which carries a horizontal flange 15 reinforced by upturned portions 16. The horizontal flange forms part - ' '; ' :' --~' ~21~971 of a tow bar bracket indicated at 17. These parts of the vehicle as described above are conventional and the details can be found by inspection of any similar vehicle.
Normally, the spare wheel for the vehicle is carried inside the cargo compartment and is a significant restriction to normal use of that cargo compartment.
The present invention therefore provides the following device which is mounted on the vehicle without the necessity for extra drilled holes or other modifica-tions to the vehicle and which firmly and rigidly sup-ports the spare wheel on the outside of the vehicle immediately rearwardly of the tail gate.
Thus, the device comprises a box member 18 which has sides 19, a top 20 and a base 21 thus defining a rectangular box shape. A rear plate 22 closes the rear of the box and provides structural strength. A front plate 23 is hingedly coupled at 24 to the bottom 21 so that it can pivot about a horizontal axis from a lowered position shown in Figure 1 to a raised position shown in Figure 2. A conventional lock arrangement 25 enables the front plate 23 to be locked in place in the closed posi-tion by a key-operated lock, the key indicated at 26.
The dimensions of the box and therefore the front plate ~2~34971 23 are such that they will just receive a conventional license plate indicated at 27 in Figure 2.
It will be appreciated that the license plate is normally mounted to the vehicle behind the box member 18 and thus must be removed from the vehicle before the box member is attached and then re-attached to the front cover plate 23 by way of the bolts indicated at 28.
The box member 18 is attached to the vehicle by four bolts. Two of the bolts indicated at 29 pass through openings in the bottom 21 of the box and through the flange 15 as best shown in Figure 3. The openings in the flange 15 are normally provided on the vehicle for attachment to a towing bracket and in this case are used to mount the box 18 without the necessity for any modifi-cation to the vehicle. The bolts ar~ passed from the outside of the vehicle underneath the flange 15 into the box 18 and have screwed thereon nuts 30 which hold the box in place rigidly upon the flange 15. The nuts are of the type which lock onto the bolt and thus prevent the bolts from being unscrewed from the exterior of the box.
The nuts are inaccessible behind the locked cover plate 23 thus providing security for mounting of the box 18 on the vehicle.
In addition, the box 18 is attached to the 12~497~L
vehicle bY bolts 31 which pass through openings in the sides 19 of the box and through conventional or pre-existing openings provided in sides 32 of the central recess 13. The bolts have a short threaded portion at the remote end which receives a nut 33 so as to clamp the bolt to the sides 32 of the bumper. Inner parts of the bolts 31 act as bearing pins for pivotal movement of sides 34 of a support member generally indicated at 35 for receiving the spare wheel. The bolts 31 again are only accessible from inside the locked box member thus providing security for the attachment of the support member 35 to the box member.
The support member comprises the sides 34 together with a rear wall 35 and a front upstanding member generally indicated at 36. These cooperate to form an open top cradle section upon which the tire of the spare wheel can rest with the dimension front to rear of the cradle being sufficient to receive the lower portion of the tire within the cradle so that the tire rests on the upper edges of the sides 34.
The sides 34 as best shown in Figure 5 have a lower edge which is inclined upwardly and outwardly. An inner edge indicated at 37 is also inclined upwardly and outwardly and then curves around the bumper 12 to a posi-. .
12~97'1 tion on the forward side of the bumper. Thus, the sidesdefine a cut-out which can wrap around the bumper in the raised position as shown in Figure 5.
The upright portion as best shown in Figure 3, includes a first portion which is tapered inwardly as indicated at 38 from the width of the cradle down to a narrower width portion indicated at 39. The tapered portion is defined by a pair of side rails 40 which are covered by a sheet thus defining effectively a closed section providing a smooth pleasing appearance. The portion 39 is defined by two rails 41 which extend from :; --~ an upper end indicated at 42 through the lower inclined section to connect to upper ends of the rails 40. Three transverse rails 43 interconnect the side rails 41 to form a complete rectangular structure which is generally . .
thlnner than its width, defining a substantially flat plate. A sheet metal surface is provided on the outer side of the rails 41 as indicated at 44 in Figure 1. The sheet metal plate leaves a first hole 45 in the upright portion. A handle is provided by two transverse rails 46, 47 and two inclined rails 48 which expose an opening 49 therebetween, the handle having a width substantially equal to the transverse width of the upright portion 39.
The handle as best shown in Figure 4 carries a ;
~2~4971 pair of actuating rods 50 which are arranged for sliding movement along the rails 41 on the inside thereof upon manual force being applied to the handle in either an upward or downward direction as required.
A central rod 51 attached again to the handle rail 47 extends through an opening in the upper rail 43 and includes a transverse opening for receiving a lock 5lA which can lock the handle in the lowered position.
: At a lower end of the actuating rods 50 there .: is carried a transverse plate 52 which is attached to each of the rods 50 at a respective end so as to be mov-able upwardly and downwardly therewith, within slots defined in an inner face of the rails 41. The upward extent of the slots limits the upward movement of the plate 52 to the position illustrated in Figure 4 in which the lower edge of the plate lies flush with the underside of a lowermost transverse rail 53.
When the handle is lowered, the plate 52 is actuated by the rods 50 to take up the position illus-trated in Figure 3. It will be noted that the plate 52 has on opposed faces, hard rubber covers 54 which provide ~ surface layers on the plate for engaging adjacent mem-bers. Specifically, a front face of one of the layers 54 engages an upstanding latch plaee 55 which is attached to , ' : - - ' ' ~2~3497~
the upper face of the box member at an intermediate posi-tion thereon and, as shown in Figure 5, extends upwardly therefrom to a position immediately rearward of the bump-er section 12.
In the position shown in Figure 3, therefore, the support member is latched into place by the plate 52 and cover 54 so that it is held against pivotal movement about the pins 31, by engagement between the plate 52 and the upstanding latch plate 55. There is no engagement between the support member and the bumper and no strain applied to the bodywork of the vehicle at any point since the full support of the device is provided by the frame of the vehicle through the flange 15.
The spare wheel is attached to the support mem-ber by sitting in the cradle and by a bolt 56 passing through the spare wheel and through an opening 57 in the plate 44. A lock 58 can be applied to the bolt to pro-vide security of attachment of the spare wheel to the support member.
A pair of springs 60 are coupled at transverse-ly spaced positions so that one end of the spring is attached to a front upper edge of the box 18 and an opposed end of the spring is attached to a front flange 61 of the cradle. As shown in Figure 5, the spring is in .
~28497~
relaxed condition in a raised position of the support and in the lowered position shown in Figure 2 the spring is extended also thus the spring provides a return force tending to lift the wheel and support into the raised position thus providing a manual assist.
If it is required to remove the support and spare wheel from the vehicle for preferred storage inside the vehicle, for example for greater security or at a time when extra storage area is not required, it is a simple matter to remove the cradle and support from the box member simply by opening the front cover 23 of the box member 18 and removing the bolts 31 which are thus available inside the box member. In addition the springs 60 can be simply unlatched from the loop members provided on the box member and the flange 61 and stored internally of the vehicle. The wheel, cradle and upright support can thus be simply retracted from the box member and inserted into the vehicle for storage.
The positioning of the box member and support centrally of the vehicle at the recess in the bumper ensures that the weight of the spare wheel is mounted centrally of the vehicle to avoid unbalancing the vehicle.
Since various modifications can be made in my '~
~ ' :
9~1 invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

DETAILED DESCRIPTION
In Figure 1 there is shown the rear of a motor vehicle generally indicated at 10 which includes a tail gate 11 of the type which can be pivoted about a horizon-tal axis at a lower edge of the tail gate so as to be raised and lowered for cargo access. Furthermore, the rear of the vehicle includes a conventional bumper 12 formed of a folded sheet metal material and in the parti-cular style of vehicle concerned, that is GMC Jimmy, there is a central recessed portion 13 of the bumper at which the bumper is reduced approximately to one-half of its depth at a portion of the order of 15 inches wide at the central section.
Beneath the bumper is provided a frame member 14 which carries a horizontal flange 15 reinforced by upturned portions 16. The horizontal flange forms part - ' '; ' :' --~' ~21~971 of a tow bar bracket indicated at 17. These parts of the vehicle as described above are conventional and the details can be found by inspection of any similar vehicle.
Normally, the spare wheel for the vehicle is carried inside the cargo compartment and is a significant restriction to normal use of that cargo compartment.
The present invention therefore provides the following device which is mounted on the vehicle without the necessity for extra drilled holes or other modifica-tions to the vehicle and which firmly and rigidly sup-ports the spare wheel on the outside of the vehicle immediately rearwardly of the tail gate.
Thus, the device comprises a box member 18 which has sides 19, a top 20 and a base 21 thus defining a rectangular box shape. A rear plate 22 closes the rear of the box and provides structural strength. A front plate 23 is hingedly coupled at 24 to the bottom 21 so that it can pivot about a horizontal axis from a lowered position shown in Figure 1 to a raised position shown in Figure 2. A conventional lock arrangement 25 enables the front plate 23 to be locked in place in the closed posi-tion by a key-operated lock, the key indicated at 26.
The dimensions of the box and therefore the front plate ~2~34971 23 are such that they will just receive a conventional license plate indicated at 27 in Figure 2.
It will be appreciated that the license plate is normally mounted to the vehicle behind the box member 18 and thus must be removed from the vehicle before the box member is attached and then re-attached to the front cover plate 23 by way of the bolts indicated at 28.
The box member 18 is attached to the vehicle by four bolts. Two of the bolts indicated at 29 pass through openings in the bottom 21 of the box and through the flange 15 as best shown in Figure 3. The openings in the flange 15 are normally provided on the vehicle for attachment to a towing bracket and in this case are used to mount the box 18 without the necessity for any modifi-cation to the vehicle. The bolts ar~ passed from the outside of the vehicle underneath the flange 15 into the box 18 and have screwed thereon nuts 30 which hold the box in place rigidly upon the flange 15. The nuts are of the type which lock onto the bolt and thus prevent the bolts from being unscrewed from the exterior of the box.
The nuts are inaccessible behind the locked cover plate 23 thus providing security for mounting of the box 18 on the vehicle.
In addition, the box 18 is attached to the 12~497~L
vehicle bY bolts 31 which pass through openings in the sides 19 of the box and through conventional or pre-existing openings provided in sides 32 of the central recess 13. The bolts have a short threaded portion at the remote end which receives a nut 33 so as to clamp the bolt to the sides 32 of the bumper. Inner parts of the bolts 31 act as bearing pins for pivotal movement of sides 34 of a support member generally indicated at 35 for receiving the spare wheel. The bolts 31 again are only accessible from inside the locked box member thus providing security for the attachment of the support member 35 to the box member.
The support member comprises the sides 34 together with a rear wall 35 and a front upstanding member generally indicated at 36. These cooperate to form an open top cradle section upon which the tire of the spare wheel can rest with the dimension front to rear of the cradle being sufficient to receive the lower portion of the tire within the cradle so that the tire rests on the upper edges of the sides 34.
The sides 34 as best shown in Figure 5 have a lower edge which is inclined upwardly and outwardly. An inner edge indicated at 37 is also inclined upwardly and outwardly and then curves around the bumper 12 to a posi-. .
12~97'1 tion on the forward side of the bumper. Thus, the sidesdefine a cut-out which can wrap around the bumper in the raised position as shown in Figure 5.
The upright portion as best shown in Figure 3, includes a first portion which is tapered inwardly as indicated at 38 from the width of the cradle down to a narrower width portion indicated at 39. The tapered portion is defined by a pair of side rails 40 which are covered by a sheet thus defining effectively a closed section providing a smooth pleasing appearance. The portion 39 is defined by two rails 41 which extend from :; --~ an upper end indicated at 42 through the lower inclined section to connect to upper ends of the rails 40. Three transverse rails 43 interconnect the side rails 41 to form a complete rectangular structure which is generally . .
thlnner than its width, defining a substantially flat plate. A sheet metal surface is provided on the outer side of the rails 41 as indicated at 44 in Figure 1. The sheet metal plate leaves a first hole 45 in the upright portion. A handle is provided by two transverse rails 46, 47 and two inclined rails 48 which expose an opening 49 therebetween, the handle having a width substantially equal to the transverse width of the upright portion 39.
The handle as best shown in Figure 4 carries a ;
~2~4971 pair of actuating rods 50 which are arranged for sliding movement along the rails 41 on the inside thereof upon manual force being applied to the handle in either an upward or downward direction as required.
A central rod 51 attached again to the handle rail 47 extends through an opening in the upper rail 43 and includes a transverse opening for receiving a lock 5lA which can lock the handle in the lowered position.
: At a lower end of the actuating rods 50 there .: is carried a transverse plate 52 which is attached to each of the rods 50 at a respective end so as to be mov-able upwardly and downwardly therewith, within slots defined in an inner face of the rails 41. The upward extent of the slots limits the upward movement of the plate 52 to the position illustrated in Figure 4 in which the lower edge of the plate lies flush with the underside of a lowermost transverse rail 53.
When the handle is lowered, the plate 52 is actuated by the rods 50 to take up the position illus-trated in Figure 3. It will be noted that the plate 52 has on opposed faces, hard rubber covers 54 which provide ~ surface layers on the plate for engaging adjacent mem-bers. Specifically, a front face of one of the layers 54 engages an upstanding latch plaee 55 which is attached to , ' : - - ' ' ~2~3497~
the upper face of the box member at an intermediate posi-tion thereon and, as shown in Figure 5, extends upwardly therefrom to a position immediately rearward of the bump-er section 12.
In the position shown in Figure 3, therefore, the support member is latched into place by the plate 52 and cover 54 so that it is held against pivotal movement about the pins 31, by engagement between the plate 52 and the upstanding latch plate 55. There is no engagement between the support member and the bumper and no strain applied to the bodywork of the vehicle at any point since the full support of the device is provided by the frame of the vehicle through the flange 15.
The spare wheel is attached to the support mem-ber by sitting in the cradle and by a bolt 56 passing through the spare wheel and through an opening 57 in the plate 44. A lock 58 can be applied to the bolt to pro-vide security of attachment of the spare wheel to the support member.
A pair of springs 60 are coupled at transverse-ly spaced positions so that one end of the spring is attached to a front upper edge of the box 18 and an opposed end of the spring is attached to a front flange 61 of the cradle. As shown in Figure 5, the spring is in .

relaxed condition in a raised position of the support and in the lowered position shown in Figure 2 the spring is extended also thus the spring provides a return force tending to lift the wheel and support into the raised position thus providing a manual assist.
If it is required to remove the support and spare wheel from the vehicle for preferred storage inside the vehicle, for example for greater security or at a time when extra storage area is not required, it is a simple matter to remove the cradle and support from the box member simply by opening the front cover 23 of the box member 18 and removing the bolts 31 which are thus available inside the box member. In addition the springs 60 can be simply unlatched from the loop members provided on the box member and the flange 61 and stored internally of the vehicle. The wheel, cradle and upright support can thus be simply retracted from the box member and inserted into the vehicle for storage.
The positioning of the box member and support centrally of the vehicle at the recess in the bumper ensures that the weight of the spare wheel is mounted centrally of the vehicle to avoid unbalancing the vehicle.
