Abstract
A safety handle for the bicycle has two handle members, spaced apart, with hand-grip members at their upper ends and attached at formations at their lower ends.
The attachment formations are formed in lower members which are releasably attached to the remainder of the handle members. This permits easy removal and reattachment of the main portion of the handle. Cross members provide for variably controlling the spacing of the handles, and the height of the handle is also adjustable. A
further, adjustable, support member for each handle member extends to a suitable frame member to provide variation in the inclination of the handles.

Description
SAFETY HANDLE FOR ATTACHMENT TO BICYCLES
FIELD OF INVENTION
This invention relates to a safety handle for attachment to a bicycle, such as for providing training for a young rider or to provide safety for handicapped riders.
BACKGROUND OF THE INVENTION
Handles for attachment to bicycles are well known but suffer from various disadvantages. For example, US patent 4,917,398 (Pinto) has a handle extending up from the rear axle. While split at its lower portion, it becomes a single member above the rear wheel with a single handle. Once attached the handle is more or less permanently attached, as the axle nuts must be removed to remove the handle.
Thus the handle is not readily removable. Also a single handle does not provide full control.
US patent no. 5,259,638, (Krauss et al) provides a single handle which is attached at a rear support near the seat and provides limited control. US patent, 5,407,222 (Harrison) has a looped handle attached at a lower end to the bicycle rear axle semi-permanently, with an adjustable support member extending to the seat attachment. Again, the handle is not readily removable. US patent 5,564,726 (Heam et al) is a single handle attached to a rear frame member adjacent to the seat position. This gives limited control and again is not readily removed and reattached. US patent 5,683,093 (Hayes) is a single handle having a split base for attachment to the rear axle and a support member for attachment to the seat fitter. Again, removal and re-attachment is not readily carried out.
Control is limited.
SUMMARY OF THE INVENTION
The present invention provides a safety handle which has spaced apart hand grips to give improved control with two spaced hand members in the attachment positions at their lower ends for attachment to the rear wheel axle of a bicycle. The spacing of the handle members, with the hand grips, is adjustable. The handle members, have upper and lower sections, with the upper sections readily detached from the lower sections.
Thus the main part of the handle assembly can easily be removed and replaced, only the lower sections being more permanently attached. The inclination that the handle renders to the bicycle, can also be adjusted. Accordingly, in the present invention there is provided a safety handle which has two spaced apart handle members with attachments at portions at their lower ends, the attachment portions have means for attachment to the rear axle of a bicycle. The spacing of the handle members is adjustable and the handle members grip portions of their upper ends.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be more readily understood by the following description, in conjunction with the accompanying drawings, in which;
Figure 1 is a front view of an assembled handle, one of the handle members shown in vertical cross section for part of its length;
Figure 2 is an exploded view of one handle member of Figure 1, showing the various items;
Figure 3 is a slightly enlarged view of the attachment of the handle member to a bicycle frame;
Figure 4 is a side view of the handle member attached to a bicycle frame; and Figure 5 is an end view of the handle member attached to a bicycle frame.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As seen in Figure 1, a handle, in accordance with the present invention, comprises two handle members 10 and 12 spaced apart in a generally parallel arrangement. At their lower ends 14 and 16 are formations 18 and 20 for attachment to a bicycle axle. Hand grips 22 and 24 are provided at the upper ends of the members. Cross members and 28 maintain the spaced relationship of the handle members, and also provide adjustment of the spacing. Two adjustable connectors 30, only one of which is seen in Figure 3, enables the angle of the handle members to be adjusted.
Figure 2 illustrates more clearly the various items comprising a handle member. The handle member shown in Figure 2 is the left hand handle member 10 of Figure 1.
The handle member 12 is of the same form, merely reversed. The handle member 10 comprises a number of items which are assembled together. Starting at the lower end, a mounting bracket on member 40 has the lower end 14 with the formation 18.
The formation 18, in the example, is a hole extending through a flattened-end portion, the hole sized to fit on the bicycle axle rod. The member 40 is hollow, but is reinforced by an inner member 42 to provide extra strength.
An insert 44 slides into the member 40, and is fastened in place by a bolt nut, not shown, passing through holes 46 and 48 in member 40 and insert 44 respectively. A
main body member 50 slides over the insert 44 and is fastened through the insert by bolt and nut, not shown, passing through holes 52 and 54. At the upper end, a hand grip member 56 has a stem portion 58 which slides into the main body member 50, and is retained in position by bolt and nut (not shown) through hole 60 in the member 54 and one of the several holes 62 in the stem portion 58. From the stem portion 58, the handle member extends sideways, at 64 and then curves round, up and inwards to provide a projection portion 66. In the assembled handle the two portions 66 would face towards each other. Before the handle portions are finally assembled, a joining member 70 is positioned over the portions 66. The joining member 70 overlaps the portions 66 sufficiently to allow for the varying of the spacing of the handle members.
Preferably a foam cover is provided for the covering of the joining member and the upper part of the hand grip members. To provide this, a length of foam tube is positioned on each hand grip member, initially extending to the stem portion, as seen in dotted outline at 72 in Figure 1. After assembly of the handle, the foam members are moved towards each other, over the joining member 70 as seen in cross-section in Figure 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As seen in Figure 1, a handle, in accordance with the present invention, comprises two handle members 10 and 12 spaced apart in a generally parallel arrangement. At their lower ends 14 and 16 are formations 18 and 20 for attachment to a bicycle axle. Hand grips 22 and 24 are provided at the upper ends of the members. Cross members and 28 maintain the spaced relationship of the handle members, and also provide adjustment of the spacing. Two adjustable connectors 30, only one of which is seen in Figure 3, enables the angle of the handle members to be adjusted.
Figure 2 illustrates more clearly the various items comprising a handle member. The handle member shown in Figure 2 is the left hand handle member 10 of Figure 1.
The handle member 12 is of the same form, merely reversed. The handle member 10 comprises a number of items which are assembled together. Starting at the lower end, a mounting bracket on member 40 has the lower end 14 with the formation 18.
The formation 18, in the example, is a hole extending through a flattened-end portion, the hole sized to fit on the bicycle axle rod. The member 40 is hollow, but is reinforced by an inner member 42 to provide extra strength.
An insert 44 slides into the member 40, and is fastened in place by a bolt nut, not shown, passing through holes 46 and 48 in member 40 and insert 44 respectively. A
main body member 50 slides over the insert 44 and is fastened through the insert by bolt and nut, not shown, passing through holes 52 and 54. At the upper end, a hand grip member 56 has a stem portion 58 which slides into the main body member 50, and is retained in position by bolt and nut (not shown) through hole 60 in the member 54 and one of the several holes 62 in the stem portion 58. From the stem portion 58, the handle member extends sideways, at 64 and then curves round, up and inwards to provide a projection portion 66. In the assembled handle the two portions 66 would face towards each other. Before the handle portions are finally assembled, a joining member 70 is positioned over the portions 66. The joining member 70 overlaps the portions 66 sufficiently to allow for the varying of the spacing of the handle members.
Preferably a foam cover is provided for the covering of the joining member and the upper part of the hand grip members. To provide this, a length of foam tube is positioned on each hand grip member, initially extending to the stem portion, as seen in dotted outline at 72 in Figure 1. After assembly of the handle, the foam members are moved towards each other, over the joining member 70 as seen in cross-section in Figure 1.
The handle members are held in a spaced relationship by means of the adjustable cross members 26 and 28. At one end, for example at the upper end, each cross member is attached to the body member 50 by, for example a bolt passing through a hole at the upper end of each cross member and passing through the holes 60.
At their lower ends, the cross members have elongated slots 82 through which pass bolts, or the like, which also pass through holes 54 of the body member 50 and hole 52 in the insert 44.
It will be appreciated that in alternate embodiments, the various components can be modified, individually or in combination such that hand grip member 56 can slide over main body 50, main body 50 can slide into insert 44, and insert 44 can slide over mounting member 40.
For attachment to a bicycle as seen in Figures 3, 4 and 5 an axle nut 84 is removed on one side of the rear wheel and a mounting member or bracket 40 is positioned on the axle rod and the nut replaced. The same actions are taken on the other side of the wheel. The brackets or mounting members 40 may be positioned on the bicycle independently, and then the rest of the handle assembled onto the brackets by sliding in the inserts 44. Altemafively, the handles can be completely assembled before attachment, in which case the axle nuts on each side should be preferably removed.
The cross members 26, 28 can be adjusted before or after attachment of the handle to the bicycle.
The inclination of the handle is maintained by the two adjustable connectors 30. One form of connector for example is a turn buckle, and is positioned between a frame member 86 of the bicycle and the mounting bracket or member 40 of a handle member. The connector is attached at one end 85 to a bracket 90 on the frame member 86 and at the other end 92 by a bolt or similar through hole 46 in the member 40. There is a connector 30 for each handle member 10 and 12.
Normally the mounting members or brackets are left permanently attached to the bicycle. The rest of the handle assembly is literally removed by removing the bolts or other which pass through the holes 46 and 48. While the rest of the bolts throughout the handle assembly are tightened up more or less permanently, conveniently the nuts 5 on bolts passing through the holes 46, 48 can be finger tight or other means such as the wing nut can be used.
The spaced grip portions, provide a large amount of control. Spaced handle members are more rigid and more controllable than a single handle. The grip portions also provide some protection if the bicycle does fall over in that the grip portions will hit the ground surface first. The height of the handle is adjustable both for the convenience of the person holding the handle and to adapt to different wheel sizes. The height adjustment is obtained by selecting which of the holes 62 a bolt passes through. The adjustability of the inclination of the handle also provides more comfort for the person holding the handle. The ability to easily remove the majority of the handle assembly, and to easily replace it provides a considerable advantage, particularly where some potential riders do not need assistance.
At their lower ends, the cross members have elongated slots 82 through which pass bolts, or the like, which also pass through holes 54 of the body member 50 and hole 52 in the insert 44.
It will be appreciated that in alternate embodiments, the various components can be modified, individually or in combination such that hand grip member 56 can slide over main body 50, main body 50 can slide into insert 44, and insert 44 can slide over mounting member 40.
For attachment to a bicycle as seen in Figures 3, 4 and 5 an axle nut 84 is removed on one side of the rear wheel and a mounting member or bracket 40 is positioned on the axle rod and the nut replaced. The same actions are taken on the other side of the wheel. The brackets or mounting members 40 may be positioned on the bicycle independently, and then the rest of the handle assembled onto the brackets by sliding in the inserts 44.
