Abstract

A quick-release arrangement for a hand-held device (30) comprising a belt clip (10) and an engagement element (20), wherein the belt clip is adapted to fit on a user'"'"'s belt or waistband, the engagement element is attachable to a hand-held device, and the belt clip has a retaining portion (17, 18) shaped to slidably accept the engagement element to a limit point and to form an interference fit with the engagement element at said limit point.

Claims

1. A quick-release arrangement for a hand tool comprising a belt clip and an engagement element, wherein:

the belt clip is adapted to fit on a user'"'"'s belt or waistband;

the engagement element is attachable to a hand tool; and

the belt clip has a retaining portion, the retaining portion comprising a U-shaped retaining lip and a U-shaped channel located behind the retaining lip to slidably accept the engagement element to a limit point and the retaining portion shaped to form an interference fit with the engagement element at said limit point, wherein the limit point is defined by a closed bottom end of the U-shaped channel, and wherein the engagement element is separated from the retaining portion by an upward movement in a direction opposite from that in which it is inserted into the U-shaped channel, wherein the interference fit is provided by resilient co-operation between a tooth and a recess and the retaining portion includes an elongate release lever having a pivot at one end and a handle at the other end, the tooth and recess being located intermediate the two ends of the release lever and the handle being accessible to a user and manually operable to displace the release lever about the pivot and in a direction away from the engagement element for separation of the tooth and the recess to allow removal of the engagement element; and

wherein the retaining portion and the engagement element are shaped to allow the engagement element to rotate slidably with respect to the retaining portion and maintain the interference fit between them.

2. A quick-release arrangement according to claim 1, wherein the engagement element has a mushroom-shaped cross section.

3. A quick-release arrangement according to claim 1, wherein the tooth is on the release lever and is shaped so as to allow a push fit of the engagement element on insertion to the belt clip.

4. A quick-release arrangement according to claim 1, wherein the engagement element is removable from and engageable with the retaining portion substantially in any angular orientation in the plane of slidable engagement to which the engagement element is rotatable, when engaged with the retaining portion.

5. The quick-release arrangement according to claim 1, wherein the limit point lies below the retaining lip.

6. A hand tool comprising a quick-release arrangement according to claim 1.

7. A hand tool according to claim 6, wherein the tool is a tape measure.

8. A quick-release arrangement for a hand tool comprising a belt clip and an engagement element, wherein:

the belt clip is adapted to fit on a user'"'"'s belt or waistband;

the engagement element is attachable to a hand tool; and

the belt clip has a retaining portion, the retaining portion comprising a U-shaped retaining lip and a U-shaped channel located behind the retaining lip to slidably accept the engagement element to a limit point and the retaining portion shaped to form an interference fit with the engagement element at said limit point, wherein the interference fit is provided by resilient co-operation between a tooth and a recess and the retaining portion includes an elongate release lever having a pivot at one end, and a handle at the other end that extends above the belt clip, the tooth and recess being located intermediate the two ends of the release lever and the handle being accessible to a user and manually operable to displace the release lever about the pivot and in a direction away from the engagement element for separation of the tooth and the recess to allow removal of the engagement element.

9. The quick-release arrangement according to claim 8, wherein the retaining portion and the engagement element are shaped to allow the engagement element to rotate slidably with respect to the retaining portion and maintain the interference fit between them.

10. The quick-release arrangement according to claim 8, wherein the limit point is defined by a closed bottom end of the U-shaped channel, and wherein the engagement element is separated from the retaining portion by an upward movement in a direction opposite from that in which it is inserted into the U-shaped channel.

11. The quick-release arrangement according to claim 8, wherein the limit point lies below the retaining lip.

12. A hand tool comprising a quick-release arrangement according to claim 8.

13. The hand tool according to claim 12, wherein the tool is a tape measure.
