Description
I
A CATAPULT
This invention relates to a catapult.
Known catapults comprise a handle, a pair of arms, a pouch and elastic material connecting the pouch to the arms. Often the elastic material twists and requires untwisting before the catapult can be used. This is irritating to users.
It is an aim of the present invention to obviate or reduce the above mentioned problem.
Accordingly, in one non-limiting of the present invention there is provided a catapult comprising a handle, a pair of arms, a pouch, and elastic material connecting the pouch to the arms, and the catapult being such that the elastic material is connected to the pouch by rotatable connecting means.
With the catapult of the present invention, the rotatable connecting means operates to prevent twisting of the elastic material. The catapult is thus always ready for use. This can be especially advantageous in situations where the catapult is needed to operate quickly, for example in fishing competitions where the catapult is used to fire bait into a fishing area in order to attract fish to the fishing area.
The catapult may be one in which the rotatable connecting means is a first peg on a first end of the elastic material adjacent the pouch, a second peg on a second end of the elastic material adjacent the pouch, a first aperture which is in the pouch and in which the first peg rotates, and a second aperture which is in the pouch and in which the second peg rotates.
The first peg may have a first end which is positioned inside the first end of the elastic material, and the second peg may have a first end which is positioned inside the second end of the elastic material. The first ends of the first and second pegs may be retained in their first and second ends of the elastic material by friction and/or an adhesive. Other means may be employed for retaining the first ends of the first and second pegs in their respective first and second ends of the elastic material.
The catapult may be one in which the pouch comprises first and second lugs, and in which the first lug has the first aperture and the second lug has the second aperture.
The pouch may include a pull member for use in pulling the pouch away from the arms for firing of the catapult. The pull member may be a teat formation. Other formations for the pull member may be employed.
The pouch will usually be made of a flexible material. Other materials may however be employed. When the pouch is made of a flexible material, then the flexible material may be a net material, or a continuous surface material.
The catapult may be one in which the elastic material is secured to the arms by a non-adjustable securing means. The length of the elastic material from the ends of the arms to the pouch is then non-adjustable.
Alternatively, the catapult may be one in which the elastic material is secured to the arms by adjustably securing means. The length of the elastic material from ends of the arms to the pouch is then adjustable.
Alternatively, the securing means may be an adjustable securing means, whereby the length of the elastic material from ends of the arms to the pouch is able to be adjusted in order to vary the firing distance of the catapult.
When the securing means is an adjustable securing means, then the catapult may be such that: (i) the elastics material extends along the arms and inside the arms, and (ii) the adjustable securing means comprises a slot which extends along each one of the arms and which has an open mouth extending along a side of the arm which faces a user during firing of the catapult, a plurality of securing formations along the length of the slot, and a securing member which is attached to an end portion of the elastic material and which is locatable in a chosen one of the securing formations and thereby to adjust the length of the elastic material.
The securing formations may be pairs of notches, with one notch of each pair being in one edge of the slot, the other notch of each pair being in the other edge of the slot, and the two notches being opposite each other.
Other securing formations may be employed.
The securing member may be a peg which is locatable in a chosen one of the pair of notches. Other types of securing member may be employed.
The securing formations may include a hole for each pair of the notches, and a pin on the peg, the hole being in a side of the arm opposite the open mouth of the slot, and the pin being locatable in the hole. Other auxiliary securing formations may be employed.
The catapult may include at least one clip for each arm, the clip being such that it fits around the arm and closes the open mouth of the slot and thereby retains the elastic material in the arm. The clip preferably locates in a groove in the arm.
The elastic material will usually be in two separate portions, with one portion extending from one of the arms to the pouch, and the other portion extending from the other one of the arms to the pouch. If desired however the elastic material may be a single piece of elastic material, for example with a centre portion of the elastic material being housed in the handle.
The catapult may include hand grip formations on the handle. The hand grip formations may be a plurality of spaced apart ribs.
The catapult of the present invention may be moulded from a plastics material. Any suitable and appropriate plastics material may be used. Any suitable and appropriate elastic material may be used.
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows a first catapult of the invention; Figure 2 is top plan view of the pouch and part of the elastic material of the catapult shown in Figure 1. with Figure 2 illustrating the connection of the elastic material to the pouch by rotatable connecting means; Figure 3 is a perspective view from the front and one side of parts of the catapult as shown in Figure 2; Figure 4 is a perspective view from the rear and one side of parts of the catapult as shown in Figure 2; Figure 5 is a front view of parts of the catapult as shown in Figure 2; Figure 6 shows a second catapult of the present invention; Figure 7 is an enlarged view from the front and one side of an arm part of the catapult shown in Figure 6; Figure 8 is a view like Figure 7 and shows the operation of adjustable securing means; Figure 9 is a view like Figure 8 but from the rear and shows the operation of the adjustable securing means just prior to location in position; and Figure 10 is a view like Figure 9 but shows the adjustable securing means fully located in position.
Referring to Figures 1 -5, there is shown a first catapult 2 comprising a handle 4, a pair of arms 6 and a pouch 8. Elastic material 10 connects the pouch 8 to the arms 6. The catapult 2 is such that the elastic material 10 is connected to the pouch 8 by rotatable connecting means 12.
The rotatable connecting means 12 comprises a first peg 14 in a first end 16 of the elastic material 10 adjacent the pouch 8. The rotatable connecting means 12 also comprises a second peg 18 in a second end 20 of the elastic material 10 adjacent the pouch 8.
The rotatable connecting means 12 also comprises a first aperture 22 which is in the pouch 8 and in which the first peg 14 rotates. A second aperture 24 is in the pouch 8. The second peg 18 rotates in the second aperture 24.
The first peg 14 has a first end 26 which is positioned inside the first end 16 of the elastic material 10. The second peg 18 has a first end 28 which is positioned inside the second end 20 of the elastic material 10. Thus the elastic material 10 is secured to the first and second pegs 14, 18, with the first and second pegs 14, 18 also being rotatably located in their respect first and second apertures 22, 24.
The first and second pegs 14, 16 each has an enlarged diameter portion 30 against which the first and second ends 16, 20 of the elastic material 10 abuts. The first and second pegs 14, 18 each has a reduced diameter portion 32 which is positioned in its first or second aperture 22. 24 and which rotates in that aperture. The first and second pegs 14, 18 each has a further enlarged diameter portion 34 which forms with the enlarged diameter portion 30 a pair of abutment members which retain the first and second pegs 14. 18 in their respective first and second apertures 22, 24, and such that the reduced diameter portion 32 of each peg 14, 18 is able to rotate in its aperture 22. 24. The enlarged diameter portion 34 is larger than the enlarged diameter portion 30. The enlarged diameter portion 30 abuts against the end 16 or 18 of the elastic material 10.
The pouch 8 has a first lug 36 and a second lug 38. The first lug 36 has the first aperture 22. The second lug 38 has the second aperture 24. The enlarged diameter portion 34 abuts against the lugs 36 or 38.
The pouch 8 includes a pull member 40 for use in pulling the pouch 8 away from the arms 6 for firing of the catapult 2. The pull member 40 has a body part4l and a teat part 43.
The catapult 2 is one in which the elastic material 10 is secured to the arms 6 by non-adjustable securing means 42. The length of the elastic material 10 from the ends 16, 20 of the arms 6 to the pouch 8 is thus fixed and non-adjustable. The elastic material 10 is in two separate portions lOa and lob. Each separate portion extends from its end of its arm 6 to the pouch 8.
The pouch 8 is made of a flexible material. The flexible material is a net material but it could alternatively be a continuous faced material. The material of the pouch 8 is secured to a rim 44 which may be made of rubber or a flexible plastics material, and which contains the first and second lugs 36, 38.
The catapult 2 is advantageous in that the elastic material 10 does not tend to twist, for example in a bag along with other equipment prior to use, or immediately after firing of the elastic material 10 recoils.
Referring now to Figures 6 -10, there is shown a second catapult 102 of the present invention. The catapult 102 is like the catapult 2 in that the catapult 102 has a handle 104, a pair of arms 106, a pouch 108, elastic material 110 and rotatable connecting means 12 which the same as the rotatable connecting means 12 in the catapult 2. The catapult 102 is different in that it has a different frame formed by the handle 104 and the arms 106, and the catapult 102 also has securing means 112. The securing means 112 secures the elastic material 110 to the arms 6 such that the length of the elastic material from ends 114 of the arms 106 to the pouch 108 is able to be adjusted in order to vary the firing distance of the catapult 102.
The catapult 102 is such that the elastic material 110 extends along the arms 106 and inside the arms 106.
The catapult 102 is also such that the securing means comprises a slot 16 which extends along each one of the arms 106. Each slot 116 has an open mouth 18 extending along a side 120 of the arms 106 which faces a user during firing of the catapult 102. The securing means 112 also comprises a plurality of securing formations 122 along the length of the slot 116. The securing means 112 further comprises a securing member 124 which is attached to an end portion 126 of the elastic material 110. The securing member 124 locates in a chosen one of the securing formations 122 and thereby to adjust the length of the elastic material 110.
The securing formations 122 are pairs of notches 128. One of the notches 128 of each pair of notches 128 is in one edge 130 of the slot 116.
The other notch 128 of each pair of notches 128 is in the other edge 132 of the slot 116. The two notches 128 are opposite each other.
The securing member 124 is a peg which locates in a chosen pair of the notches 128.
The securing formations 122 include a hole 134 for each pair of notches 128. The securing formations 122 also include a pin 136 on the peg.
The hole 134 is in a side of the arm 106 opposite the open mouth 118 of the slot 116. The pin 136 locates in the hole 134 of the chosen pair of notches 128.
The catapult 102 includes a clip 138 for each arm 106. The clip 138 is such that it fits around the arm 106 and closes the open mouth 118 of the slot 116 and thereby retains the elastic material 110 in the arm 106. The clip 138 locates in a groove 140 in the arm 106.
The elastic material 110 is in two separate portions llOa and 11Db.
One portion 11 Oa extends from one of the arms 106 to the pouch 108. The other portion 11Db extends from the other one of the arms 106 to the pouch 108.
The pouch 108 includes a pull member 142 for use in pulling the pouch 108 away from the arms 106 for firing of the catapult 102. The pull member 142 comprises a body part 144 which is attached to the pouch 108, and a grip part 146 which is gripped between the user's forefinger and thumb.
The pouch 108 is made of a flexible material. More specifically, the pouch 108 is made of a net material.
The elastic material 110 connects to the pouch 108 by the rotatable connecting means 112 as mentioned above.
The handle 104 has hand grip formations in the form of spaced apart ribs 160. The ribs 160 are on both sides of the handle 104.
The handle 104 and the arms 106 form a frame of the catapult. The frame is able to be moulded in a plastics material. The elastic material 110 may be any suitable and appropriate elastic material. The pouch 108 is made from a net plastics material. The pull member 142 may also be made of a plastics material. The catapult 102 can thus be easily manufactured, and also such that it is light and uses a minimum of plastics material. This enables the catapult 102 to be manufactured in a cost effective manner which compares favourably with comparable known catapults. The catapult 102 is for use by anglers in firing bait from the pouch 108 to different distances. The longer the length of elastic material 102 between the arms 106 and the pouch 108, the longer is the firing distance of the catapult 102. The catapult 102 is able to be used to fire bait to different distances to attract fish to the areas where the bait is fired. Any suitable and appropriate bait may be employed including maggots, bread and boilies.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, other types of rotatable connecting means 12 may be employed. The shape of the catapult frame formed by the handle and the arms may be different from those shown. Other types of pouch 8, 108 may be employed. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention.
