Abstract

A dart board includes at least one flexible slot which includes at least two apertures for receiving the dart tips. A through hole is defined between the two apertures so as to expand the flexible slot and the dart tips having different sizes can be clamped by the flexible aperture. A guide plate is fixed to the retaining frame so as to guide the dart tips successfully stick on the dart board and activate the electronic film switches of the dart board. The size of the retaining frame can be reduced because of the fixed guide plate. The guide plate and the retaining frame are engaged by engaging members and engaging holes so that the guide plate can be easily replaced. The guide plate can be fixed to the retaining frame.

Claims

1. A dart board comprising:

at least one target block and each target block having at least one flexible slot which includes at least two flexible apertures which are adapted to receive the dart tips, a through hole defined between the at least two apertures, the flexible apertures clamping dart tips with different sizes.

2. The dart board as claimed in claim 1, wherein the target block has at least one protrusion to contact electronic film switches.

3. The dart board as claimed in claim 1, wherein a bottom plate is connected to an underside of the at least one flexible slot.

4. The dart board as claimed in claim 1 wherein the flexible slot communicates with the insertion apertures.

5. A dart board comprising:

at least one target block and each target block having at least one flexible aperture which includes at least one through hole, the flexible apertures clamping dart tips with different sizes.

6. The dart board as claimed in claim 5, wherein the target block has at least one protrusion to contact electronic film switches.

7. The dart board as claimed in claim 5 wherein each flexible aperture communicates with an insertion aperture.

8. A dart board comprising:

at least one remaining frame and at least one guide plate connected to at least one retaining frame and each guide plate comprising a plurality of guide apertures, the guide plate being fixed to the retaining frame.

9. The dart board as claimed in claim 8 wherein the retaining frame has at least one engaging hole and the at least one guide plate has an engaging member which is engaged with the engaging hole.

10. The dart board as claimed in claim 8 wherein the retaining frame and the at least one guide plate are an one-piece member.

11. The dart board as claimed in claim 8 wherein the target block has at least one engaging protrusion and the at least one guide plate has an engaging member which is engaged with the at least one engaging protrusion.

12. The dart board as claimed in claim 8 wherein the guide apertures are flexible apertures.

13. A dart board comprising:

at least one retaining frame and at least one guide plate connected to the at least one retaining frame and each guide plate comprising a plurality of guide apertures, the guide plate having extensions pushing against the backing so that the guide plate is fixed.
