Description
. I 2097~38 I~IG (~b~ LIFI
The present invention relates to lifts and especially to lifts suitable for big game animals.
Various lifts have been proposed for supporting big game animals for skinning or for loading into vehicles. Some of the known hoists are mounted on vehicles.
This means that they can not be used independently as is sometimes required. Other known lifts are relatively complex devices that are difficult to assemble. It is common with the known lifts to suspend the animal using a cable, an arrangement that does not provide a stable support for skinning and dressing.
The present invention aims the provision of a novel lift that overcomes or ameliorates various difficulties with the prior art.
According to the present invention there is provided a game lift comprising:
a tripod base including a main beam and two legs;
lifting arm means pivotally mounted on the tripod for pivotal movement about a substantially horizontal axis;
a winch mounted on the tripod base; and a cable wound on the winch and connected to the lifting arm means such that winding the cable on the winch will raise the lifting arm means about the pivot.
In use, an animal is supported on the lifting arm and the lifting arm is pivoted upwardly to raise the animal. This eliminates the suspension of the animal using the cable as is common with the prior art. The tripod base is preferably collapsible. This may be accomplished by seating the upper ends of the legs in sockets mounted on~the main beam of the tripod. The lifting arm means may preferably be detached from the tripod base by pulling a pivot pin connecting the two.
The lifting arm means is preferably an assembly constituted by a lift arm, a ~ ~ ' '`.. . ' '`

-2- 2097~38 thrust bar removably mounted on the lift arm to project upwardly from the lift arm near the pivot and a tension link joining the thrust bar and the lift arm. With this arrangement, the cable from the winch is led to a pulley at the free end of the thrust arm and then back to a dead end on the tripod base, preferably on the main beam adjacent the winch. To avoid the need to re-thread the cable through the pulley on the thrust bar whenever the lift is set up, the thrust bar may be mounted in a stored position on the main beam by appropriate fittings, for example a socket to receive one end of the main beam and a bracket to engage the bracket for the tension link. A single or double game hanger may be removably mounted on the end of the lift arm.
An embodiment of the present invention will be described in the following by way of example.
In the accompanying drawings which illustrate the exemplary embodiment of the present invention:
Figure 1 is a view of the hoist assembled and in use;
Figure 2 illustrates the components of the lift disassembled;
Figure 3 is a detail view showing the assembly of the legs and the lift arm to the main beam; - ;
Figure 4 is detail showing the storage position of the thrust bar on the main beam and the assembly of the thrust bar on the lift arm;
Figure S is an isometric showing the installation of the tension link;
Figure 6 is an isometric view showing an optional double lift assembly; and Figure 7 is a view along line 7-7 of Figure 6.
Referring to the accompanying drawings Figure 1 illustrates a lift 10 according to the present invention. This includes a tripod base 12 with a lift assembly 14 pivotally mounted on the base. The lift assembly includes a lift arm 16, a thrust bar 18 2097~38 projecting upwardly from the lift arm and a tension link 20 joining the thrust bar and the lift arm adjacent their ends remote from the pivotal connection to the tripod base. At the outer end of the thrust bar is a pulley 22 around which is wrapped a cable 24. The cable leads to the pulley from a winch 26 mounted on the tripod base. From the pulley, the cable leads to a dead end 28 adjacent the winch on the tripod base.
At the outer end of the lift arm 16 is a transverse game support 30 that suspends a game animal when the hoist is in use.
The tripod base 12 of the hoist includes a main beam 32. This has a bottom end 34 that extends away from the main length of the beam at an obtuse angle so that in use the bottom ends of section 34 will be generally horizontal. A pin 36 projects upwardly from the bottom end section 34 adjacent its free end. The pin is used to engage a hold-down for the lift. This may be a hitch ball opening in a vehicle bumper, a tie-down ring on a truck bed, or any other hold-down that may be available.
Part way along the main beam 32 is a winch bracket 38. This supports a winch base 40 at an appropriate orientation on the main beam. The base carries a winch drum 42, a hand crank 44 and a drive train coupling the crank to the drum so that turning the hand crank will drive the drum. The base also carries a lock 46 for locl~ng the winch against rotation.
Adjacent the winch bracket 38, also mounted on the main beam 32 is a hook -; - ~ -48 that serves as the dead end 48 for the end of the cable. ~ -Spaced along the top side of the main beam are a socket 50 which engages ~ ~-the end of the thrust bar 18 and a hook 52 that engages a link bracket 54 on the thrust bar -as will be described more fully in the following. -At the free end of the main beam 32 is a leg support assembly 56. This includes two square tuba 58 joined by a similar cross tube 60 into an equilateral triangle ol~oi ?.~ :~
4 2097~38 configuration. The bottom ends of the tubes 58 are open to serve as sockets for the ends of the legs. At the top of the legs support assembly are two side pivot lugs 62 and a center lug 64. The side lugs 62 have aligned bores 66. The center lug 64 has a through bore 68 that is aligned with the bores 66. Fastened to the leg support assembly by a chain 70 is a pivot pin 72 dimensioned to fit through the bores 66 and 68. The pin has a large square head 74 that carries a ring 76 so that the pin can be set and pulled readily by hand.
The two legs 78 are square sections with reduced ends 80 that fit slideably into the socket ends of the tubes 58. A shoulder 82 on the end of the leg abuts the end of the associated tube 58 when the leg is fully seated.
At the lower end of each leg is a foot plate 84 that supports the leg, especially on soft ground.
At its inner end the lift arm 16 has an enlarged head separated into two pivot lugs 86. Each lug has a through bore 88 that aligns with the bore 66s and 68 in the leg support assembly 56 when the lugs 86 are fitted between the lug 64 and the respective lugs 62. Insertion of the pin 72 through a11 of the bores links the lift arm to the tripod base.
A thrust bar socket 90 is carried on the upper side of the lift arm near the inner end carrying the pivot lugs 86. Near the opposite, outer end, the lift arm is fitted with a tension link bracket 92, which is illustrated most particularly in Figure 5. This bracket includes two side plates 94 projecting to the top of the lift ann and an end plate 96 supported by the side plates and having a U-shaped notch 98. At the free end of the lift arm is a fixed hook 100.
The thrust bar 18 is another square tube with a reduced size end 102 to fit into the socket 90 on the lift arm. The link bracket 54 mounted near the opposite end of the thrust bar includes two side plates 104 and an end plate 106 with a U-shaped notch 108. At the outer end of the thrust bar 18 are two parallel support plates 110 that receive ic~ "..... .. . .
-s -the pulley 22 between them. The pulley is held in place using a through pin 112.As illustrated particularly in Figure 5, the tension link 20 has a square end plate 114 that fits into the link bracket 54 behind the end of plate 106, with the round body of the link fitting into the notch 108. Near the end plate 114, the leg has an obtuse angled bend 116. At the end opposite end plate 114 is a similar end plate 118 that engages the link bracket 92 on the lift arm, with the body of the link fitting into the notch 98.
The game support 30 is a square tube 120 with a ring 122 mounted on the top, at the center. The ring 122 fits on the hook 142 at the end of the lift arm. At opposite ends of the tube 120 are rings 124 that engage eyes on the ends of respective hooks 126. The hooks point outwardly and are used for hooking to the legs of a game animal so that the tube 120 acts as a spread bar.
An optional double game support attachment 28 is illustrated in Figures 6 and 7. This is attachment includes a downwardly open channel 130 with a pair of lugs 132 at the innermost end of the channel, projecting from the flanges. A cross bar 134 joins the lugs. Adjacent this inner end of the channel, the channel web 136 is removed to provide an opening 138. Spaced slightly from the outer end of the channel is a cross plate 139 extending across the two flanges of the channel. Across the end of the channel is a square tube 140 carrying two hooks 142. Each of the hooks 142 may be used to support a game support 30 as described above. The attachment is mounted on the lift arm by passing the lift arm through the opening 138, and lowering the cross plate 139 into the hook 100 at the end of the lift arm.
The lift is transported disassembled as shown in Figure 2. This assembly can be bundled into a fairly small package consisting of five main pieces plus the game support. To assemble the hoist, the legs are first inserted into the leg support as illustrated by arrows A and B at Pigure 3. The li~t arm is then connected to the leg support as shown -6- 2097~38 by arrow C in Figure 3, and the pin 72 is inserted. The thrust bar is then removed from the main beam as shown in Figure 4. This involves slackening the cable so that the end of the thrust bar can be disengaged from the socket 50 and the link bracket S4 can be disengaged from the hook 52. The reduced end of the thrust bar is then inserted into the socket 90 on the lift arm as shown by the arrow F in Figure 4. The tension link 20 is then installed as shown by the arrows G in Figure 5. This completes the basic assembly except for the mounting of the game support 30 on the end of the lift arrn. As will be observed, this is a simple process that can be carried out by a single person using no tools and a minimum of effort.
