Spacer for spacing a tool from a tool stand
A spacer ( 1 ) for spacing a tool such as a drill motor from a tool stand such as a drill stand, the spacer ( 1 ) comprising a spacer body ( 2 ) and a locking member ( 3 ), the spacer body ( 2 ) having first ( 4 ) and second ( 5 ) opposing faces, the locking member ( 3 ) extending from a first end ( 6 ) thereof adjacent to the first face ( 4 ) to a second end ( 7 ) thereof adjacent to the second face ( 5 ), the locking member ( 3 ) being able to slide relative to the spacer body( 2 ) along a direction from the first end ( 6 ) to the second end ( 7 ), the first end ( 6 ) and the second end ( 7 ) each being provided with at least one locking surface( 10, 11 ), wherein the spacer ( 1 ) is arranged such that at application of a locking force each locking surface ( 10, 11 ) of one of the first and second ends ( 6, 7 ) transmits the locking force to each locking surface ( 10,11 ) of the other of the first and second ends ( 6, 7 ).
1. A spacer for spacing a tool from a tool stand, the spacer comprising a spacer body and a locking member, the spacer body having first and second opposing faces, the locking member extending from a first end thereof adjacent to the first face to a second end thereof adjacent to the second face, the locking member being configured to slide relative to the spacer body along a direction from the first end to the second end when the tool and the tool stand are in an attached state, the first end and the second end each being provided with at least one locking surface, wherein the spacer is arranged such that at application of a locking force each locking surface of one of the first and second ends transmits the locking force to each locking surface of the other of the first and second ends.
2. The spacer of claim 1 , wherein each of the locking surfaces is elongate so as to have a length in a direction non-parallel to the direction from the first end to the second end.
3. The spacer of claim 1 , wherein the first and second ends are complementary, such that the first end of one spacer can receive or be received within the second end of another spacer by running over one another along their lengths in a lengthwise direction.
4. A spacer for spacing a tool from a tool stand, the spacer comprising a spacer body and a locking member, the spacer body having first and second opposing faces, the locking member extending from a first end thereof adjacent to the first face to a second end thereof adjacent to the second face, the locking member being able to slide relative to the spacer body along a direction from the first end to the second end, the first end and the second end each being provided with at least one locking surface, wherein the spacer is arranged such that at application of a locking force each locking surface of one of the first and second ends transmits the locking force to each locking surface of the other of the first and second ends,
wherein the first and second ends are complementary, such that the first end of one spacer can receive or be received within the second end of another spacer by running over one another along their lengths in a lengthwise direction, and
wherein the first and second ends each have at least one corresponding tab nose and recess along their lengths, such that as the first and second ends are run over one another along their lengths, each corresponding tab nose and recess engaging one another at a given relative position of the locking surfaces.
5. The spacer of claim 4 , wherein the at least one corresponding tab nose has at least one tab edge and the at least one recess has at least one recess edge, such that when the tab nose and the recess engage one another a sliding motion in at least one lengthwise direction is prohibited by at least one tab edge meeting one recess edge.
6. The spacer of claim 4 , wherein the spacer comprises at least one biasing member, which acts to bias the locking member relative to the spacer body, so as to bias the at least one tab nose and recess into engagement once the relative position is reached.
7. The spacer of claim 3 , wherein one of the first and second ends is provided with a stop, which prevents movement of the first and seconds ends relative to one another past the stop.
8. The spacer of claim 1 , wherein the tool stand extends along a direction substantially parallel to a direction of extension of the locking member and the direction from the first end to the second end along which the locking member slides relative to the spacer body.
