According to the preferred embodiment, the board frame 10 comprises a plurality of concentric ribs 11 and radially extending rectilinear ribs 12 which are intersected with the concentric ribs 11 to form a plurality of receiving recesses 24 on the board frame 10.
The target blocks 20 are disposed at the receiving recesses 24 of the board frame 10 respectively. Each of the target blocks 20 comprises a block body 21, a predetermined amount of target materials 22, and a block panel 23.
The block body 21, which is preferably made of plastic, has a material compartment 211 and two openings 212 aligning with the material compartment 211. In particular, the material compartment 211 has an elongated structure that the two openings 212 are aligned with each other through the material compartment 211. Accordingly, the block bodies 21 can be configured with different sizes, shapes, and cross sections corresponding to the size and shape of the receiving recess 24.
The target materials 22 are made of sisals and filled within the material compartment 211 of the block body 21. Accordingly, the target materials 22 are long sisal raw material being compressed and formed in a bundle configuration to form an elongated sisal bar to pass through the block body 21. The sisal bar is then cut at the two openings 212 of the block body 21 for fitting the target material 22 in the material compartment 211 of the block body 21.
The block panel 23 is affixed to one of the openings 212 of the block body 21 to form a bottom panel of the respective block body 21 so as to retain bottom of the target materials 22 within the material compartment 211 of the block body 21.
As shown in
Alternatively, an edge of the block panel 23′ is foldably coupled with an edge of the respective block body 21′ at one of the openings 212′ thereof. In other words, the block panel 23′ is integrated with the block body 21′ edge-to-edge, wherein the block panel 23′ forms a cover panel before the target materials 22 are filled in the block body 21′. Therefore, after the target materials 22 filled within the material compartment 211′, the block panel 23′ is folded to couple with the block body 21′ and to close the respective opening 212′ thereof, as shown in
According to the preferred embodiment, each of the target blocks 20 further comprises an adhering element 24 to adhere the bottom of the target materials 22 to the block panel 23. In other words, the bottom of the target materials 22 is adhered to the block panel 23 to retain the target materials 22 within the material compartment 211.
Each of the target blocks 20 comprise a cushioning element 25 provided at the bottom of the target materials 22 to couple with the block panel 23. According to the preferred embodiment, the cushioning element 25 can be made of rubber or EVA foaming material to form the cushion bottom of the target materials 22. It is worth mentioning that the cushioning element 25 is provided at the inner side of the block panel 23, wherein the adhering element 24 can be applied to the cushioning element 25 such that the bottom of the target materials 22 can be affixed to the block panel 23 with cushioning effect.
As shown in
(1) Configure the target materials 22 in a bundle form to form the sisal bar.
(2) Guide the sisal bar to extend through one or more hollow block bodies 21.
(3) Cut the sisal bar at the two openings of each of the block bodies 21 for fitting the target materials 22 in the material compartment 211 of the block body 22.
(4) Affix the block panel 21 to one of the openings 212 of each block body 21 to form the target block 20.
(5) Couple the target blocks 20 on the board frame 10 to form the dartboard. In particular, the target blocks 20 are disposed at the receiving recesses 24 of the board frame 10 respectively.
According to the preferred embodiment, in the step (1), the target materials 22 are bundled by the following steps.
(1.1) Comb the long sisal raw materials used for the target materials, wherein bad sisal raw materials are picked and removed to ensure the quality of the target materials.
(1.2) Pack the raw materials by a hemp packing machine to compress and collect the raw materials in a bundle form so as to form the elongated sisal bar. It is worth mentioning that the amount of raw materials being bundled together is predetermined according to the cross sectional area of the block body 21. In other words, the cross section of the sisal bar should match with the cross section of the block body 21.
Accordingly, the tightness of the sisal bar impacts the dart shooting and pulling. If the sisal made target materials are too tight, the dart cannot be shot and pulled easily. It the sisal made target materials are too loose, the shot dart cannot station at the target block 20. The moderate sisal can make the dart shoot and pull easily. It can expand to fill in the hole that is shot by the dart when the dart is pulled out, such that no crevice will be formed after the dart is hit and removed from the target block. The raw materials being wrapped and packed can produce the target blocks 20 with proper tightness via the hemp packing machine for easy shooting and pulling.
In the step (2), the sisal bar is slidably passing through a plurality of the block bodies 21. Accordingly, the block bodies 21 are aligned with each other that the material compartments 211 of the block bodies 22 are aligned to from an elongated channel for the sisal bar passing therethrough. The numbers of block bodies 21 being aligned with each other depend on the length of the sisal bar.
In particular, the sisal bar is compressed that the cross section of the sisal bar is slightly smaller than the cross section of the block body 21. Therefore, after the sisal bar is guided to pass through the material compartment 211 of the block body 21, the sisal bar 21 will be expanded to bias against the inner wall of the material compartment 211 of the block body 21, so as to ensure the target materials 22 being fitted in the material compartment 211 of the block body 21.
As it is mentioned above, the sisal bar is slidably passing through two or more block bodies 21. When the sisal bar is cut in the step (3), the semi-product of the target block 20 is formed. Accordingly, a predetermined number of the semi-products can be formed at the same time to enhance the mass production of the target blocks 20. It is worth mentioning that the cross section of the block bodies 21 should be the same in order to enable the sisal bar passing therethrough.
In the step (4), the present invention further comprises the following steps.
(4.1) Apply the adhering element 24 to adhere the bottom of the target materials 22 to the block panel 23.
(4.2) Provide the cushioning element 25 at the bottom of the target materials to couple with the block panel.
(4.2) Affix the block panel 23 to the block body 21 to enclose the respective opening 212 thereof.
(4.3) Trim the deckle edge of each of the target blocks 20 to avoid the partial lengthy sisals from protruding.
(4.4) Apply different colors on each target block 20 (e.g. applying red color on the red target block 20) to distinguish the different scoring blocks 20.
Accordingly, the steps (4.1) and (4.2) can be formed in one single step of applying the adhering element 24 to the cushioning element 25 such that the bottom of the target materials 22 can be affixed to the block panel 23 with cushioning effect.
