Description
A tool for prising apart a joint
This invention relates to a tool for prising apart a right-angled joint formed by pinning a first length of wood into a recess in the end of a second length of wood, and, in particular, to a tool for prising apart a joint of a beehive frame.
A variety of tools can be employed for the task of prising apart a right-angled joint formed by pinning a first length of wood into a recess in the end of a second length of wood. Thus, a combination of tools such as a hammer, a screwdriver, a pliers, and a pincers can be employed for the purpose.
Where the right-angled joint is formed as part of a British
Standard beehive frame, it is important that the joint is disassembled by a beekeeper in such a way that the components of the frame are not damaged, as they are intended to be reused. As part of the disassembly of the frames the beekeeper endeavours to save the waste beeswax as he cleans the parts of the frame. This cleaning includes the removal of any wax and foundation from the grooves on the inside of the side bars.
Thus, when using the above combination of tools, care must be taken so as not to damage the frame, and therefore, the disassembly of the frame cannot be rushed. Furthermore, when there are a large number of frames to be disassembled, the work can be time-consuming.
It is an object of the present invention to overcome the disadvantages associated with the disassembly of a right-angled joint as hereinbefore described.
Thus, the invention provides a tool for prising apart a right-angled joint formed by pinning a first length of wood into a recess in the end of a second length of wood, which tool comprises a first arm and a second arm, each arm having a handle at a handle end thereof and a jointengaging member at the other ends thereof, the arms being pivotally connected together at a point between the handle ends and the other ends, the joint-engaging members being movable between a spaced-apart configuration and a closed configuration as the handles are closed, with the joint-engaging member on the first arm extending beyond the jointengaging member on the second arm and with the joint-engaging members being displaced laterally one from the other, such that, in use, the first length of wood is engaged by the joint-engaging member on the first arm and the end of the second length of wood is engaged by the joint-engaging member on the second arm, with the joint-engaging members in the spaced-apart configuration, and with the joint being prised apart as the joint-engaging members are moved to the closed configuration.
An advantage of the tool according to the invention is that the right-angled joint is taken apart by simply addressing the joint with the tool and closing the handles thereof. The bringing together of the tool handles causes the first length of wood to be prised out of the recess in the second length of wood in a steady movement. This steady separation of the joint results in little or no damage to the first and second lengths of wood.
In one embodiment of the invention, the first length of wood is an end bar of a British Standard beehive frame and the second length of wood is a side bar of the beehive frame.
An advantage of the use of the tool in accordance with the invention, where the right-angled joint is between the side bar and the end bar of a beehive frame, is that such frames are dismantled and rebuilt a number of times during their life, and thus, minimal damage to the frame components is important, as well as the speed and ease of the dismantling operation.
Preferably, the joint-engaging member on the first arm has two parallel engaging pieces which are spaced apart, such that, in the closed configuration, the engaging pieces are positioned to each side of the joint-engaging member on the second arm.
An advantage of this arrangement is that the tool can be used from either side of the frame, with one or other of the engaging pieces engaging the end bar. As the frame has two end bars attached at each end thereof to a side bar, there are four right-angled joints to be prised apart and each of these joints can be prised apart by orientating the tool in the appropriate direction.
Further, preferably, the two parallel engaging pieces are spaced apart such that the narrow width of the side bar is a snug fit therebetween.
An advantage of this arrangement is that the side bar can be located between the two engaging pieces, which assists in preventing a turning motion as the handles are closed to prize apart the end bar from the side bar.
In a further embodiment of the invention, each engaging piece has a joint-engaging side and an opposing side from which a pin extends.
An advantage of the pin extending from the engaging piece is that it can be employed to remove any wax and foundation from the grooves on the inside of the side bars.
In a further embodiment of the invention, a V-shaped pin extractor is positioned on the end of the joint-engaging member on the second arm.
An advantage of the V-shaped pin extractor is that the same tool can be used to prise apart the joint and to remove pins from the separated lengths of wood.
The invention will be further illustrated by the following description of an embodiment thereof, given by way of example only with reference to the accompanying drawings in which:
Fig. 1 is a perspective view from above and to one side of a tool for prising apart a right-angled joint formed by pinning a first length of wood into a recess in the end of a second length of wood in accordance with the invention;
Fig. 2 is a plan view from above of the tool of Fig. 1;
Fig. 3 is a view of the tool of Fig. 1 in a spaced-apart configuration and engaged with a right-angled joint between an end bar and a side bar of a British Standard beehive frame; and
Fig.4 is a view of the tool of Fig. 1 in a closed configuration with the right-angled joint prised apart.
Referring to Fig. 1, there is illustrated generally at 10, a tool, in accordance with the invention, for prising apart a right-angled joint formed by pinning a first length of wood into a recess in the end of a second length of wood, which tool 10 comprises a first arm 11 and a second arm 12, each arm 11,12 having a handle 13 at a handle end 14 thereof and a joint-engaging member 15, 16 at the other ends 17, 18, respectively thereof.
The arms 11, 12 are pivotally connected together at a point 19 between the handle ends 14 and the other ends 17, 18, the joint-engaging members 15, 16 being movable between a spaced-apart configuration and a closed configuration as the handles 14 are closed.
The joint-engaging member 15 on the first arm 11 extends beyond the joint-engaging member 16 on the second arm 12, with the jointengaging members 15, 16 being displaced laterally one from the other.
In use, the first length of wood is engaged by the joint-engaging member 15 on the first arm 11 and the end of the second length of wood is engaged by the joint-engaging member 16 on the second arm 12, with the joint-engaging members 15, 16 in the spaced-apart configuration, and with the joint being prised apart as the joint-engaging members 15, 16 are moved to the closed configuration.
In this embodiment of the invention, the tool 10 is dimensioned for prising apart a right angled joint formed between the first length of wood which is an end bar of a British Standard beehive frame and the second length of wood which is a side bar of the beehive frame.
The joint-engaging member 15 has two parallel engaging pieces 20, 21, which are spaced apart, such that, in the closed configuration, the engaging pieces 20, 21 are positioned to each side of the joint-engaging member 16 on the second arm 12. The two parallel engaging pieces 20, 21 are spaced apart such that the narrow width of the side bar of the beehive frame is a snug fit therebetween.
The engaging piece 20 has a joint-engaging side 22 and an opposing side 23, from which a pin 24 extends. Similarly, engaging piece 21 has a joint-engaging side 25 and an opposing side 26, from which a pin 27 extends. The pins 24, 27 can be employed, in use, to remove any wax and foundation from grooves on the inside of the side bars.
A V-shaped pin extractor 28 is positioned on end 29 of the jointengaging member 16 on the second arm 12.
Referring to Fig. 2, a plan view from above of the tool 10 is illustrated. The tool 10 is in the closed configuration and the engaging pieces 20, 21 are positioned to each side of the engaging member 16.
Referring to Fig. 3, the tool 10 is illustrated in a spaced-apart configuration and is engaged with a right-angled joint, shown generally at 30, the joint 30 being between an end bar 31 and a side bar 32 of a British Standard beehive frame, shown generally at 33. The end bar 31 is pinned into a recess 34 in the side bar 32. The second side bar of the frame 33 has been removed for clarity. The joint-engaging member 16 is resting on end 35 of the side bar 32 and the joint-engaging side 22 of the engaging piece 20 is contacting inner surface 36 of the end bar 31.
The pin 24 on the engaging piece 20 can be used to clean out a groove 37 on inner surface 38 of the side bar 32. The groove 37 is used for retaining foundation within the frame 33.
