Abstract

A protector for the shank of a screw 18 comprises a tube resiliently provided with portions for engaging the shank. The tube may be of concertina form (Figure 1) or have axial ribs 34 (Figure 4). The tube may be made from PVC, silicone, polyethylene or rubber. <IMAGE>

Description

A PROTECTOR FOR A SCREW OR THE LIKE The invention relates to a protector for a screw or the like.
A known protector for a screw or the like comprises a simple plain cylindrical tube made from resilient material such as thermoplastic rubber which is pushed onto the threaded shank of a screw or stud to protect it. A given protector will only fit one particular diameter of screw or stud. Also, the known protector may be difficult to remove.
According to the invention there is provided a protector for a screw or the like comprising a tube to lie over the shank of a screw or the like, and portions to contact the shank of a screw or the like, said portions being resiliently provided to be capable of resilient outwards movement.
As the portions are capable to resilient outwards movement, the protector of the invention can protect screws or the like of different shank diameters.
Also, as a protector is in contact with the screw or the like at particular portions rather than the entirety of its inner surface, it is easier to remove.
The surface of the tube is preferably continuous circumferentially. Complete cover for the shank of the screw or the like is therefore provided.
Preferably, the tube is resilient to permit outwards movement of the portions. Preferably, the portions are capable of resilient outwards movement over at least lmm and most preferably between 2mm and 4mm. By providing a movement capability of at least lmm it is ensured that the protector will be able to protect a range of screw diameters and a suitably large range of diameters can be covered by a protector with portions that can move 2mm to 4mm.
The portions may be spaced over the length of the tube but preferably each portion extends over the length of the tube. Conveniently, the tube may include a longitudinal rotational axis of symmetry.
In a preferred embodiment, the tube comprises at least one inwards fold and the inner surface of the or each fold comprises a said portion. In this way, opening out of the or a fold will enable a screw or the like of larger diameter to be received in the tube and the resilience of the material of the fold will retain the protector. The tube may comprise a plurality of equally spaced inwards folds. The tube may be in concertina form. Suitably, there may be more than four folds and in a preferred embodiment there are eight folds. The or each inwards fold may be smoothly rounded in profile. Where the tube is in concertina form, the connection of one fold to the next may also be smoothly rounded. Preferably, the or each fold is at least imm deep and may be 2mm deep.Suitably, the or each fold may be of uniform thickness which may be imam. Where the tube is in concertina form the entire tube may be of uniform thickness.
In an alternative embodiment, at least one projection may project inwardly from the tube and the inner surface of the or each projection may comprise a said portion. The or each projection may be resiliently deformable. The or each projection may comprise an axial rib.
The protector may be made from any suitable material and may be made from PVC, silicone, LDPE or thermoplastic rubber.
Two embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which: Fig. 1 is an end view of the protector of the first embodiment; Fig. 2 is a side view of the protector of Fig. 1; Fig. 3 is a side view of the protector of Fig. 1 on a stud; and, Fig. 4 is a perspective view of the second embodiment of the protector.
The protector 10 of the first embodiment comprises a tube 12 of uniform cross-section along its axial length. The tube 12 is also of uniform thickness and in transverse cross-section has a generally sinusoidal form comprising eight inwards folds 14 equi-spaced around the tube 12 and connected to form a continuous concertina shape. The inner surface 16 at the trough of each fold 14 comprises the aforesaid "portion11.
Fig. 3 shows the protector 10 on a screw 18. The shank 20 of the screw is received in the tube 12 such that the screw threads 22 of the screw 18 contact the portions 16 and partially open out the inwards folds 14. The shank 20 of the screw is entirely covered by the protector 10 and it will be seen that the protector could receive screws with shanks of smaller or larger diameter in which case the folds 14 would be opened out to a lesser or greater extent. Suitably, the minimum internal diameter of the tube 12 may be 6.Smm and the maximum external diameter 9.5mm. The wall thickness of the tube may be lmm. The tube may be made from PVC, silicone, LDPE or TPR, for example.
Fig. 4 shows the second embodiment in which the protector 30 comprises a cylindrical tube 32 provided on the interior surface with four equi-spaced inwardly projecting rectangular ribs 34. The inner surfaces 36 of the ribs 34 comprise the aforesaid portionsn.
In use, the shank of a screw is introduced into the tube 32 and the ribs 34 will deform resiliently to an extent depending upon the diameter of the screw shank.
In this way a number of different screw diameters can be accommodated. The protector may be made from PVC, silicone, LDPE or TPR, for example.
The protectors 10 and 30 of the two embodiments may be made by extrusion.
