Abstract

A system for fixing stays 10 to cycle mudguards 2 uses two separate items 5 that are fixed by mechanical means to either or both of the inside or outside surface of the mudguard near to the opposite edges of the mudguard. The part of the item 5 which connects to the stays 10 can be designed in such a manner to receive a stay of any construction. Any method of fixing the stay to this part of the item can be incorporated. The part of the item that comes into contact with the mudguard surface is shaped to the contour of the mudguard and the other part of the item can be angled so that it lines up with the stay. <IMAGE>

Description

IMPROVED SYSTEM FOR FIXING STAYS TO MUDGUARDS This invention relates to an improved system for fixing stays to cycle mudguards.

Fixed bridges as applied to cycle mud guards are a well known item used for securing the metal stays to the sides of the mudguard section. A typical cross section of a cycle mudguard fitted with a conventional fixed bridge is shown in figure 1. As can be seen from this cross section the fixed bridge is secured to the mudguard section by two rivets normally positioned at the centre of the mudguard section. The fact that these bridges are secured at the centre of the mudguard section means that any flexibility in the metal bridge itself is transferred to the stays thus giving the stays less rigidity at the point where they are fixed to the bridge.

According to the present invention there is provided two plastic parts fitted to each edge of the mudguard section. Each part being secured by a rivet or other mechanical means close to the edge of the mudguard section. This means that the stay will be held in a more rigid state. Although this design can apply to stays which are fixed by a draw bolt arrangement it is very suitable for the fixing of parallel stays since a self tapping screw can be used to secure the special stay retaining clip to the plastic part.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1. shows the application of a conventional fixed bridge where the two rivets secure the bridge at the centre of the mudguard section.

Figure 2. shows the application of two plastic or metal parts fixed by rivets or other suitable means to the mudguard section so that the two parts can receive a self tapping screw which in turn fixes the stays to the parts. The part which comes into contact with the surface of the mudguard can be designed to follow the contour of the surface of the mudguard.

Figure 3. shows the application of the two plastics or metal parts fitted to each edge of the cycle mudguard where the part incorporates a spigot which snaps into a hole in the mudguard. The drawings show two typical applications one where the spigot fits from the outside of the mudguard and the other where the spigot fits from the inside of the mudguard.

Figure 4. shows the use of the plastics or metal parts when used with conventional draw bolts.

Figure 5. shows the use of the plastic or metal parts, where the parts snap over a rib which is formed at the edge of the mudguard.

Referring to the drawing figure 1. it can be seen that the the conventional metal bridge 3. is secured by two rivets 1. to the mudguard 2. This method of securing the fixed bridge to the mudguard section is traditional but the rigidity of the bridge is reduced when the rivets are positioned along the centre line of the mudguard section. The rigidity is dependant upon the thickness of the material used for the bridge.

Figure 2. shows the application of the two plastic or metal parts 5. fixed to the mudguard section 2. by rivets 4. This construction produces a more rigid arrangement since the rivets are nearer to the edge of the mudguard section.

The part 5. is ideally suited to plastics but could be made of a suitable metal.

One advantage of producing the part 5. in plastic is that it will receive a self tapping screw thus eliminating the need for threading the hole to receive a conventional set screw.

Figure 3. shows the application of the plastic part 8. where the spigot 7. fits into the hole in the mudguard 2. from the inside surface of the mudguard.

The plastic part 8. can also be of a different design where the application of the spigot 7. fits into the hole in the mudguard from the outside surface of the mudguard.

Figure 4. shows a similar arrangement to that in figure 2 but where the part 5 is designed to receive a draw bolt assembly 9. which secure the stay 10 as shown.

Figure 5. shows a method of securing the part 13 to the mudguard by using a rib 11. at the edge of the mudguard 2. The rib would secure the part 13 laterally and a small amount of adhesive 14 would secure the part 13 longitudinally. Again the part 13 could be designed to receive either a draw bolt to retain a single stay or the self tapping screw to retain a parallel stay.

Claims

1. An improved system for fixing stays to mudguards where two plastic or metal parts are fixed to either the inside or outside surface near the edge of the mudguard section so that stays can be fixed to these parts on either side of the mudguard section following one of the conventional methods. The two plastic or metal items are shaped so that part of the item follows the profile of the surface near the edge of the mudguard section and that the other part of the item is designed to receive a stay of any practical design. The two items can be fixed on the outside or inside surface of the mudguard by rivets or other mechanical means.

2. An improved system for fixing stays to mud guards as claimed in Claim 1.

where the items are fixed to both the inside and outside surfaces of the mudguard by any mechanical means.

3. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part of the item that receives the stay is designed to receive a draw bolt arrangement.

4. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part of the item that receives the stays is designed to receive a self tapping screw and a stay retaining part.

5. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part of the item that receives the stay is designed in such a way as to receive and secure a stay which has been grooved along its length to locate the stay longitudinally along its length.

6. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part of the item that receives the stay incorporates an integral clip arrangement to secure the stay in a longitudunal pre set position.

7. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part of the item that receives the stay incorporates a threaded form that can receive a threaded stay so that the stay can be positively located longitudinally.

8. An improved system for fixing stays to mudguards as claimed in Claim 1.

where the part that fits to the mudguard snaps over a rib or groove at the edge of the mudguard. The item will in this instance have legs that will fit over both surfaces of the mudguard. The item can be retained longitudinally along the length of the mudguard by the use of adhesive or some mechanical means.
