Abstract

Claims (43)

1 . A plate for a dumbbell or barbell, the plate comprising a body, the body comprising:

at least two primary weight portions extending in a direction radially out from a plate axis passing through a centre point of the plate, the at least two primary weight portions forming at least part of a total weight of the plate; and

two or more additional weight portions removably connectable to the body, such that connecting and disconnecting the two or more additional weight portions incrementally varies the total weight of the plate, the body further comprising:

for each of the two or more additional weight portions, a void arranged to receive the respective additional weight portion, the void defined by the at least two primary weight portions;

wherein the at least two primary weight portions are spaced from each other around the plate axis, each void formed in a space between two of the at least two primary weight portions.

2 . The plate as claimed in claim 1 , comprising a latching mechanism to removably connect the two or more additional weight portions to the body, the latching mechanism comprising:

one or more catch members, and a corresponding passage to receive of the one or more catch members, each of the one or more catch members and the corresponding passage forming a latching point, the plate optionally comprising biasing means to urge the one or more catch members to remain in the corresponding passage.

3 . The plate as claimed in claim 2 , wherein the one or more catch members move into and out of the corresponding passage in a first direction into the corresponding passage, the first direction being perpendicular to the plate axis.

4 . The plate as claimed in claim 3 , wherein the corresponding passage is larger than the one or more catch members in a direction perpendicular to the first direction, to accommodate relative movement of the two or more additional weight portions and the at least two primary weight portions.

5 . The plate as claimed in claim 2 , comprising handles arranged to actuate the one or more catch members, the handles formed on a radially outer edge of the two or more additional weight portions or the at least two primary weight portions.

6 . The plate as claimed in claim 5 , wherein the handles are formed in recesses extending radially inwards from the radially outer edge of the two or more additional weight portions or the at least two primary weight portions.

7 . The plate is claimed in claim 2 , wherein the one or more catch members are provided in a hollow section formed in a primary weight portion of the at least two primary weight portions or an additional weight portion of the two or more additional weight portions, and projects out of an opening to engage the corresponding passage, and wherein the primary weight portion of the two or more additional weight portions having the one or more catch members also comprises solid sections to provide weight.

8 . The plate as claimed in claim 2 , further comprising locating means arranged to locate the two or more additional weight portions relative to the at least two primary weight portions, the locating means comprising a shoulder extending from one of the at least two primary weight portions and the two or more additional weight portions, and a socket for receiving the shoulder in the other of the primary weight portion and the additional weight portion.

9 . The plate as claimed in claim 1 , wherein the body comprises:

a mounting portion defining a passage extending around the plate axis, for mounting the plate on a dumbbell bar or barbell bar, the at least two primary weight portions extending radially out from the mounting portion.

10 . The plate as claimed in claim 9 , wherein a radially inner rim of each of the two or more additional weight portions abuts the mounting portion.

11 . The plate as claimed in claim 1 wherein:

each primary weight portion of the at least two primary weight portions comprises a pair of opposing sidewalls each having a length extending radially out from the plate axis; and

for each void, a first radially extending edge of the void is formed by a sidewall of the pair of opposing sidewalls of a first primary weight portion of the at least two primary weight portions, and a second radially extending edge of the void is formed by a sidewall of the pair of opposing sidewalls of a second primary weight portion of the at least two primary weight portions, the second primary weight portion of the at least two primary weight portions adjacent to and spaced from the first primary weight portion of the at least two primary weight portions.

12 . The plate as claimed in claim 11 , wherein:

each void has a width measured around the plate axis, between the first radially extending edge and the second radially extending edge of the void;

each primary weight portion of the at least two primary weight portions has a width measured around the plate axis, between the pair of opposing sidewalls of the primary weight portion;

the voids have the same width as each other; and

the at least two primary weight portions have the same width as each other.

13 . The plate as claimed in claim 1 , wherein the two or more additional weight portions are arranged to be removably connectable to the body by latching points formed, at least in part, in the at least two primary weight portions.

14 . The plate as claimed in claim 1 , wherein each additional weight portion of the two or more additional weight portions comprises a pair of opposing sidewalls; and wherein each additional weight portion of the two or more additional weight portions is removably connectable to the at least two primary weight portions at both sidewalls of the pair of opposing sidewalls.

15 . The plate as claimed in claim 1 , wherein the at least two primary weight portions comprise only primary weight portions arranged on opposing sides of the plate axis, and the voids to receive the two or more additional weight portions are arranged on the opposing sides of the plate axis, between the primary weight portions.

16 . The plate as claimed in claim 1 , wherein each void is open to a radially outer rim of the body to allow the two or more additional weight portions to be removed and inserted in a radial direction.

17 . The plate as claimed in claim 1 , wherein the two or more addtional weight portions and the at least two primary weight portions are evenly distributed around the plate axis.

18 . A dumbbell or barbell kit comprising:

one or more pairs of plates, each plate in a pair having an equal weight to the other plate, wherein each plate comprises a body, the body comprising:

at least two primary weight portions extending in a direction radially out from a plate axis passing through a centre point of the plate, the at least two primary weight portions forming at least part of a total weight of the plate; and

two or more additional weight portions removably connectable to the body, such that connecting and disconnecting the two or more additional weight portions incrementally varies the total weight of the plate, the body further comprising:

for each of the two or more additional weight portions, a void arranged to receive the respective additional weight portion, the void defined by the at least two primary weight portions;

wherein the at least two primary weight portions are spaced from each other around the plate axis, each void formed in a space between two of the at least two primary weight portions; and

a bar for mounting the one or more pairs of plates on, wherein the plate axis of each plate extends along the bar when the plate is mounted on the bar.

19 . The dumbbell or barbell kit as claimed in claim 18 , comprising:

the one or more pairs of plates comprising at least two pairs of plates, each plate in a pair of plates being the same weight, and different pairs of plates having different weights from other pairs,

wherein:

each plate of the one or more pairs of plates has a thickness along the plate axis and a radius extending from the plate axis;

all plates of the at least two pairs of plates have the same radius; and

different pairs of plates have different thicknesses.

20 . The dumbbell or barbell kit as claimed in claim 18 , wherein the body of the each plate comprises: a mounting portion defining a passage extending around the plate axis, for mounting the plate on a dumbbell bar or barbell bar, the at least two primary weight portions extending radially out from the mounting portion, wherein a projection extends radially into the passage of the mounting portion, wherein the projection is discontinuous around the plate axis and is configured to engage a corresponding groove in the dumbbell bar or barbell bar such that engagement of the projection and groove prevents rotation of the plate around the axis.
