Abstract
A cage-type animal trap with two opposed animal access openings that can operate in a one-door-opening configuration or a two-door-opening configuration. The trap has an over-center set mechanism for holding one or both doors open to allow access through the corresponding trap access openings. The set mechanism includes a pivotally mounted set lever coupled to the doors of the trap by an actuating member. A bait pedal is movably mounted inside the trap with a trip rod and link assembly secured to the pedal and to the set mechanism so that when an animal enters the trap, the weight of the animal moves the pedal, causing the trip rod and link assembly to actuate the set mechanism. Upon actuation, the set lever pivots past its over-center position to allow movement of the actuating member which enables one of the doors to move from an opened position to a closed position when the trap is operating in a one-door-opening configuration, and both of the doors to move from the opened position to the closed position when the trap is operating in the two-door-opening configuration.

Embodiment
In the process of the preferred embodiment that description the present invention illustrates in the accompanying drawings, use the particular technology term in order to reach clearly purpose.Yet the particular technology term of described selection is not to mean limitation of the invention, is understandable that, each particular element comprises all technically can operate the equivalent substitution form of finishing similar effect in a similar manner.
As shown in Figure 1, simple gate cage trapper of the present invention totally by Reference numeral 10 expressions, comprises the box-like cage with elongated bottom 12 and respective tops 14 and opposing sidewalls 16 and 18, preferably is shaped and folding processing by single of gauze.Sidewall extends the plane that is parallel to each other substantially to form between the longitudinal edge 24,26 at the longitudinal edge 20,22 of bottom 12 and top 14.Bottom and top also are parallel to each other substantially.The trapper rear portion is by rear wall 28 closures, and described rear wall is fixed on bottom 12, top 14 and the sidewall 16,18 by Connection Element 30.
In embodiments of the invention as shown in Figure 1, bottom 12, top 14 and sidewall 16,18 comprise wire element 32,34, this wire element welds the hole 36 with the formation essentially rectangular on its crosspoint, and this sidewall is crooked up and down in the mode at cardinal principle right angle from bottom and top respectively.Rectangular opening 36 is about 1 " square (1 " square).
Alternatively, basket structure can comprise bottom and two upwardly extending sidewalls, and the elongated cover plate or top 40 (referring to the accompanying drawing 12-14) that are preferably formed by pressing metal plates are installed on this sidewall.Rectangular top is made up of a metallic plate substantially, and this metal plate shape becomes the edge with bending on the respective metal silk of trapper main body.Such cage trapper has been disclosed in copending application U.S.No.11/097, in 195 (also having transferred the assignee of this application), is incorporated herein it in full.
For animal is remained in the inclosure, trapper cage door mechanism is provided, represent with Reference numeral 44 that totally it comprises the elongated cage door of preferably being made by metallic plate 46.The top of cage door 46 is connected the top pivotly by bent projection thing 48.The end of the installation cage door of trapper is called front end herein, and the end of contiguous rear wall is called the rear end.
Cage door locked plate 50 horizontal location, and fixing along the lower limb 52 of cage door face board.Selectively be, if lockplate 50 with compacting or other method moulding on the cage door, then it can be used as the integral part of cage door 46.U-shape lock is decided wire yoke bar 60 and is had bottom 62, when the cage door is in the closed position, and the bight that these 62 wedge jails, bottom are limited by the outer surface 54 of the top edge 64 of cage door locked plate 50 and cage door, as shown in Figure 1.The end 66 of this yoke bar rotatably is connected with sidewall 16,18 by cage hingen flap 70 with 68, and is held element 72 and keeps.
As the zoomed-in view that is mounted of accompanying drawing 1A and accompanying drawing 2 separately shown in, provide torque wire spring 74, in a downward direction towards cage door bias voltage yoke bar 60.One end of yoke bar 60 inserts the centre bore 73 of torsionspring circle 75, and an arm 71 of torsionspring engages yoke bar 60, another arm 77 deflections and engage top 14 of torsionspring.By this structure, spring 74 is pressed to the cage door with the yoke bar.
The bottom 76 of cage door locked plate 50 comprises the hole (not shown) that receives lanyard assembly one end, and this lanyard assembly totally adopts Reference numeral 78 to represent, as shown in Figure 3.Lanyard assembly 78 comprises stay cord 80, and this stay cord passes the hole of plate 50, and prevents to be drawn out by the stopper 82 on the cage door link that is fixed on stay cord.From stopper 82, stay cord 80 passes the below of the bottom 62 of yoke bar 60, and the edge is upward to the outer surface 54 through cage door 46, with top of crossing support wire 84 and the top that arrives top 14.The end of the stay cord relative with cage door link has the eyelet 86 that is connected on the stay cord, to be used to connect following setting bar.
See attached Figure 4 and 5 for details, the overall center set mechanism of Reference numeral 90 expressions that adopts is installed on the top at top 14, and comprise by edge thrust 94 and be fixed on set mechanism flat board 92 on the longitudinal edge 24,26 at top 14 that thrust 94 bendings of described edge are to be looped around the corresponding site of gauze.The setting shaft bar 96 of horizontal expansion is installed on dull and stereotyped 92.This support 96 comprises two upwardly extending arms 98,99, and each arm 98,99 is respectively adjacent to the two ends of support, and each arm 98,99 all has substantially circular hole 100 and passes from it.
Roughly each end of the setting bar 102 of U type is connected on the arm 98,99 of support 96 pivotly, moves to forward facing position on the opposite side that is in support from the position backward on the side that is in support thereby can turn over less times greater than the angles of 180 degree.A preferred embodiment of setting bar as shown in Figure 6.As hereinafter be about to discuss like that, trapper also operably designs the setting bar that moves less than in 180 scopes of spending to have, so that the motion of described bar from a side of support to opposite side is unnecessary.
Particularly, it should be understood by one skilled in the art that to construct set other structure that bar moves in less or bigger angular range.Generally speaking, the size of required angular movement depend on the cage door from closed condition to opening required stay cord stroke, and be connected to radial distance between the point on the setting bar setting rod axis and stay cord.Especially, the required angle that must pass through of described setting bar is that desired location when the cage door is opened and cage door are closed so that stay cord poor between the point on the setting throw of lever during tensioning no longer.Can effect not arranged above the stroke after the described angle, but only increase the slackness of stay cord the further motion of cage door.See that from practical point of view slackness to a certain degree is useful,, thereby can reduce the required dimensional accuracy of part because it increases manufacturing tolerance.Preferably, pulling rope length is than 1 inch of the about length of required minimum length.What certainly can understand is, uses long more stay cord, and stay cord just has big more slackness in the position that the cage door is closed.
In fact, the disclosed structures that the setting bar moves about 180 degree are desirable, in view of the minimum setting bar radius of this geometry permission, i.e. minimum radial distance between the stay cord tie point of setting on rod axis and the setting bar.Can almost flatly lean against on the top in view of set bar under unbuckled state, disclosed setting bar structure also allows minimum trapper section.Yet, set this angular movement of bar and do not require that stay cord is tensioned through corresponding distance.On the contrary, stay cord be tightened up and in fact control " effectively " scope of the stay cord stroke of cage door motion can be more much smaller than the total kilometres of setting bar.
Be convenient to manually move setting bar 102 by the setting bar handle 104 that is installed on the bar.Handle 104 has central channel 105 and embedded groove 106, and this central channel 105 is used to receive the yoke portion of U type bar 102, and this embedded groove 106 is used to hold the bar that connects stay cord 80 and connects terminal eyelet (eyelet) 86.By making bar pass eyelet 86, thereby lanyard assembly is connected on the bar.Then, handle is installed on the bar and is fixing by screw etc.Under the constraint of the groove 106 in handle 104, therefore stay cord 80 is prevented from sliding along bar.When the cage door is opened, to close at the spring of the cage door that torsionspring 74 provides under the acting in conjunction of bias voltage and cage door own wt, lanyard assembly is tightened.
During setting and triping, bar 102 has " eccentric (over-center) " action, thus center set mechanism 90 can be reliably, operation repeatedly.As shown in Figure 7, the pivot axis 122 of setting bar 102 and the tension force vector of stay cord 80 define free travel zone 126 and symmetrical substantially zone 128 together, and in described symmetrical region 128, stroke is braked device 129 and limits.Separately the line (power at this line medium pulling rope is passed through pivot axis) in these two zones is represented balancing plane 130.
Limit 2 points that have of the direction of wire-pulling force or vector: near the stay cord fulcrum 132 of trapper front above the cage door, and stay cord is connected to the stay cord point of contact of setting on the bar 102 134.Because the location of the stay cord fulcrum 132 of close cage door can not change, the direction of wire-pulling force only changes along with the angle of setting bar.If stay cord point of contact 134 is in free travel zone 126, bar can freely-movable, and wire-pulling force impels bar to rotate, and allows the cage door to close.If stay cord point of contact 134 is in restriction stroke zone 128, wire-pulling force impels equally to be set bar and rotates, but in the opposite direction, and only turns to it and run into brake device 129.The result is, when setting bar 102 when " the cage door is closed " position is drawn by the free travel zone, the power bias voltage of stay cord is directed to the direction of closing trapper.When the motion of setting bar continues and through overbalance or equilibrium point, that is, during " off-centre " plane, the power bias voltage of stay cord 80 is directed setting bar against brake device 129 with pulling, open or set condition thereby trapper remained on, shown in accompanying drawing 7 and 8.In described set condition, the axis of stay cord 80 is in the below of pivot axis line 122, and trapper is stable, if so that slightly shake its set mechanism 90 of can not triping.According to preferred embodiment, brake device is combined in to be set in the bar handle 104, and described handle directly contact with dull and stereotyped 92 surface, setting up the bias voltage under the open mode, thereby does not need upward independent brake device 129 of flat board.
When center set mechanism 90 activated, bar 102 upwards motion in restriction stroke zone 128 was away from brake device 129.When stay cord axis the time, reach the eccentric point or the plane 130 of balance, and set mechanism is in poised state, as shown in Figure 9 by pivot axis line 122.Continue motion when setting bar, set mechanism enters sets the unbuckled state that bar can free-running operation.In described free travel zone 126, the stay cord axis is in the top of pivot axis line 122, as shown in Figure 10.
The bias voltage size of open mode determines by open mode bias voltage offset distance 138, and as shown in Figure 7, described offset distance is when setting bar and brake device offset, the minimum range of the vertical survey between the force vector of pivot axis 122 and stay cord 80.As described before, the force vector of stay cord is limited with the point 134 that stay cord is connected with the setting bar by the stay cord fulcrum 132 near the cage door.
Open mode bias voltage offset distance 138 has two functions.The first, it launches (selffiring) automatically by opposing provides a kind of stable set condition, and the second, it has produced and has started the required moment of torsion of set mechanism.Therefore, the power of triping or the moment of torsion of triping can be adjusted by the position of adjusting brake device, and the described moment of torsion of triping equals the product of wire-pulling force and open mode bias voltage offset distance.The brake device position of setting the wire-pulling force vector is more near pivot axis 122, and the required power of triping is just more little, and the brake device position of setting the wire-pulling force vector is more away from pivot axis 122, and the required power of triping is just big more.Equally, the moment of torsion of triping also can be by raising or reducing pivot axis and adjust, and such mode can correspondingly increase or reduce open mode bias voltage offset distance equally.
The set mechanism 90 of triping is by providing enough big moment of torsion to realize to overcome the moment of torsion of triping to setting bar 102.According to the present invention, reduce owing to when mechanism trips, open bias voltage (open-bias) moment of torsion, thereby unclamp when mechanism when the direction of triping moves becomes easier.Help the conversion of set condition and unbuckled state like this.
Forward accompanying drawing 11 to, release gear 120 comprises trip rod and link assembly, and shown in Reference numeral 142, this assembly can be dynamically connected with the bait pedal 144 that movably is installed on the bottom 12, thereby described bait pedal is arranged in the zone of besieging animal.Trip rod and link assembly 142 have connecting rod element 146, and this connecting rod element 146 and general reference numeral are that 148 trip rod movably is connected.Trip rod 148 has roughly L type structure, and this structure has first elongated member 150 and second arm 152, and this first elongated member 150 roughly aligns with connecting rod element 146, and this arm 152 engages along the general horizontal direction extension and with the top 154 of pedal 144.If desired, the free end of second arm can remain in the sidewall 18 by the keeper 153 that is fit to.
Joint between connecting rod element 146 and trip rod 148, total shown in Reference numeral 156, be formed between the connection ring portion 158,160 of two elements.Similarly, also be that the ring portion 157,159 that is connected by two elements realizes at connecting rod element 146 and joint between the lever arm 116.Also can use other joint design, as long as they can provide the abundant exercise degree of freedom between trip rod and the connecting rod and between connecting rod element and lever arm, to realize setting the eccentric action and the caved in linkage as shown in Figure 1 (collapsible linkage) of bar 102.
Bait pedal 144 usefulness act on the power input position of center set mechanism 90.The bottom margin 162 of pedal 144 is the bottoms that rotatably are fixed on cage by crooked crimping 164, and described crooked crimping 164 is evenly spaced apart and around an one metal wire bending of gauze along bottom margin 162.The top 154 of pedal 144 is fixed on the trip rod.
When animal entered the animal inclosure, the weight of animal applied downward pressure to the top 154 of bait pedal 144, facilitated pedal to pivot along its bottom margin 162.The ring portion 159 that is connected that described motion facilitates trip rod and link assembly 142 will set bar 102 pulls down the enough distances of action spot, and starts the rotation of setting bar with the pulling force of abundance.Along with under the effect of the deadweight of torsionspring 74 and cage door 46, to set bar 102 is drawn to this support from the rear side of setting shaft bar 96 front side by the tightening force of stay cord transmission, surpass balancing plane 130 in case set the bar rotation, set bar and reach free travel zone 126.Described motion allows cage door 46 to move to the closed position from open position, thereby animal is captured in the animal inclosure.
Handle 166 preferably approximately is installed on the set mechanism flat board 92 at the trapper center, and along its length longitudinal extension.Groove 106 in the handle 104 has skew with respect to the center of setting bar 102, so stay cord 80 is settled along a side of handle 166.
In order under its cage door closing state trapper 10 to be set, trapper at first is placed on ground or the stayed surface.Catch handle 104, and it 14 is lifted from the top, setting bar 102 pivots backward from its forward facing position, pass through equalization point up to it, on described equalization point, in response to the power that applies by the stay cord bias voltage by torsionspring 74, this handle can easily move with as required with the upper face or brake device 129 adjacency of the flat board 92 at bar rear positions place.The reverse of bar causes stay cord 80 to be pulled on direction backward, thereby makes cage door 46 be set in load situation to rotation and with the cage door upward in thrust 48 upper edges.After finishing described process with a hand, trapper has been set and has been finished, and waits entering of animal and triggers trapper.
In order to lure that animal enters trapper into, suitable bait is inserted into the inside of the pedal 144 in the trapper.When animal entered trapper and sets foot on pedal 144, pedal was rotated down, thereby facilitated trip rod and link assembly 142 traction trip rod downwards.Thereby pull down extension arm 116, crank arm portion 115 and the ring portion 159 of setting bar 102, like this, the shape of given setting bar impels bar rotation and U type parts upwards to lift.In case cross balancing plane, the deadweight of torsionspring and cage door 46 facilitates the cage door to be rotated down, thereby closes inner space 70 rapidly, with animal trap in cage 10.
In the process that cage door 46 is rotated down, the yoke bar 60 of biased downward, promotion by torsionspring 74, upwards be pressed on the upper face 54 of cage door 46, when the cage door was in the closed position, this yoke bar was placed on the corner that the outer surface 54 of the top edge 64 of cage door locked plate 50 and cage door 45 limited.Under these conditions, if animal attempts to open the cage door, the bottom 62 compressing cage door locked plates 50 of yoke bar rotate up the cage door to stop animal.
When the user wanted to discharge the animal of trapping, the user can follow with setting the similar program of trapper.Originally, the motion backward of handle 104 tension operation stay cord 80, because this stay cord passes below the bottom 62 of locking yoke bar 60, so this stay cord facilitates this yoke bar 60 upwards to lift, this yoke bar breaks away from the top of cage door locked plate under the promotion of stay cord 80.In view of the above, by handle 104 being lifted overbalance point from the top and being made that setting bar 102 moves to rear positions, the people who is positioned at the trapper rear discharges the animal of traping.
As used herein, term " trip rod and link assembly " is defined as to has the most widely implication and can comprise stay cord or other trigger mechanisms, thereby can be used for traction setting bar 102 when pedal 144 is rotated down when.In addition, those skilled in the art understand that trip rod can form single-piece with connecting rod, for example can be by the mode of casting.The bait pedal also can constitute one with bar.Can interact with animal other release gears of (for example pull) can substitute pedal 144 and constitute the part of frizzen.
According to the present invention, second embodiment with trapper of center set mechanism is described in the accompanying drawing 12, and accompanying drawing 12 has been showed the setting bar 170 under " setting " state.Pivot axis is limited by 172,174 of two positions on the up-right support 173, and this support 173 is fixed on the top 40, and the stay cord 80 of tensioning simultaneously 178 draws and sets bar 170 in the position.Setting bar 170 is the plane basically, and it is connected on the bait pedal 180 by combined type (collapsible) linkage 182 that can cave in.When the bait pedal was rotated down, described linkage pulled down the portion of cranking arm 181, set bar 170 with rotation and crossed eccentric position, thereby can close trapper cage door in the mode that the front has been described.Trapper is set by identical mode.
The 3rd embodiment of center set mechanism of the present invention is described in the accompanying drawing 13.As shown in the figure, present embodiment uses the monoblock type trip rod of revising 184 and has longitudinal extension handle 188 compactnesses mounted thereto and sets bar 186.Set bar 186 and have integrated ring portion 185 and hook portion 187.This ring portion 185 is held the end 183 of wire rack mount 181, and this support 181 is fixed on the metallic plate top 240.This end 183 can rotate in ring portion 185 also as the rotating shaft of setting bar 186.
When setting bar 186 lifts with the setting trapper from cage door closed position when, the hook portion 187 that departs from by terminal 183 rotating shafts that limit begins rotation from them in the position of trip rod back, then this hook portion is by the top 189 of the trip rod of the either side of their contact lower concave parts 191 and the path of trip rod 184 being lifted the desired location of 240 tops to the top.On desired location, trip rod supports the bait pedal 180 above the trapper bottom.When masterpiece was used on the bait pedal 180, trip rod pulled down hook portion 187, provided moment of torsion via the offset distance of hook portion and rotating shaft to setting bar 186, overcame the open mode bias voltage and triped (startup) trapper.Distance between ring portion and the top is greater than the length of hook portion, and therefore hook portion can not be subjected to the obstruction at top when setting bar and rotate.Set the motion that bar continues self, hook portion and trip rod break away from, and allow the lower concave part of trip rod to return once more to be resisted against on the top.
As shown in Figure 14, in the 4th embodiment, the monoblock type trip rod 184 and the wire rack mount 181 of the modification of the embodiment in accompanying drawing 13 are used to set bar 190, and this setting bar directly is connected with trip rod, thereby setting bar and trip rod combine always.Yet when having only trapper to set, " knee " portion 192 that sets bar just can be bonded together with the end 183 of wire rack mount 181.Particularly, from the position of triping that the cage door is closed, set bar 190 and be pulled rearward, thereby the end 183 of knee 192 and wire rack mount 181 is bonded together.In case be bonded together, the setting bar will adopt with the same mode of other embodiment and rotate to the center set position, as shown in Figure 14.
