DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 is a perspective view showing an embodiment of a container $pparatus for an object t~o be dropped (hereunder referred to as a drop object) according to the a present icrrention. This ao~ainer apparatus houses therein a drop object ~rrhich functions as a paint marker or s hydrographic conditions measuring device or the like, to be dapped by a ~~ansport airplane such as an e~ircraft dying in the air to a water surface of sea, Iake or the like, or fro land or the like, The container apparatus comprises a container main body 't, main body coupling means 2, main body releasing means 3, an automatic extending cable 4, and a plumb bob 5.
In FtG. ~ , the ~ntainer main body 1 houses therein a drop object which exhibits a predeterrt~ined function, to be dropped by the xransport airplane 'not shown in the frgures), and is formed from thick paper, plastic or metal or the like in the st~rape of a ~riinder with a circular or polygons! cross~sectioh. The container main body i is just di~ded vertically into two portions (1 a and 7 b), and as shown in FIG, 3, one ends (upper ends) of the t~rvo portions at one end section of the container main body 1 are connected by a hinge 6 and the other ends (lower ends) at the apposite end s~tion of the container main body 1 are able to be deooupled from each other to both sides, as indicated by the arrows A and B. Speciily, as shovm in FiC. 1; the shape of the c~ntainsr main body 1 is a circular cylinder witft an outer diameter of approximately 120mm and a total length of approximately 1 QOamm, for example;
and one of division lines 7 between the vertically divided main body members 1 a and 1 b is shown on the side wail of the container main body 1.
The main body coupling means 2 is provided at the opposite end section near the bottom of the container main body 1. This main body coupling means 2 couples the other ends of the two porlaons of the container main body 1 to prevQnt the other ends from being decoupled, and as an examples consists of a tape member wound around the outer peripheral surface of the opposite end section of the container main body 1. specifically. an adhesive tape with a width of approximately 100mm and a length of appro~cirna'tety 22bmm is wound around the outer peripheral surface of the apposite end section.of the container main body 1. ~rdingly, it is possible with a simple ntate~al to couple the other ends at the opposite end section Qf the container main body 7 to prevent the other ends firom being decoupted. This main body coupling means Z consisting of the tape member can bye cut with a card type member as described befnw.
The main body releasing means $ are attached to opposite side waif portions of the container main body 1. The main body releasing means 3 release the coupling " CA 02424446 2003-04-04 of the main body coupling means 2, thereby deaoupling fhe other ends at the opposite end section of the container main body 1, and as art ex2rr~ple, consists of a cord type memE~er,v~hich is connected to the automatic extending cable ~, described below to cut the tape member serving as the main ~dy coupling means 2 by the e~ctensiQn of the aufomatic extending cable ~4. Specifically; a type of line known as °'sflken gut", ~nrhich is a strong fine used in fishing, can be used for the cord type member serving,as the main body releasing means 3. This cord type member (3'j is not limited do the silken gut mentioned above, and a line made of ynthetic fibers or metal or the like may also ire used. By using such members, it is possible with a simple construction to retea$e the coupling by the main body coupling means 2, thereby decoupling the other ends at the opposite end section of the carrtainer main body '( .
Then, as shown in FIG. i and FIG. 2, the" cord type member (a) is arranged in an elongated loop shape in a manner to loop around the inside and outside of the container main body 1, along each of the division lines 7 on the opposite side well portions of the container main body "1, and also to loop around the lowver edge of the tape memfaer (Zj at a Iflwer end portion thereof, and to be connscted to the automatic extending cable 4 described below at ~n upper end portion thereof.
Accordingly, the cord type member (3) is pulled upward due to the extension of the autorrtatic extending cable 4 to cut through the tape member (2). At this time, it becomes possible to facilitate the arcing if a tape easy to be cut is used as the tape member (2), 2nd incision is made at the lower edge of the tape member (2), to loop around the incision with the lower end portion of the looped cord type member (~.
The automatic extending cable 4 is connected to the one end section (upper end section) of ~e container main body 1. This automatic exr~ending cable 4 is for operating the main body releasing means 3, and extends from the upper end section of the container main body 1 to be attached to the transport airplane (not shown in the figures). The automatic extending cable 4 consists of, for example, a flexible rope member A rfng B tn be hooked onto a part of the aircraft or the like serving as the transport airpls.ne is attached to an end portion of tile rope member.
plccordingly, if the entire container apparatus is dropped into the air while this ring 8 is hooked onto the part of the aircraft or the lifte, then the automatic e~ctending cerble 4 vn'il exteryd automatically, thereby operating the main body releasing means 3.
' CA 02424446 2003-04-04 b /~ plumb bob S~is in~:orporated in the inside of the container main,body 1.
This plumb bob S is for adjusting a trajectory followed by the entire conta~irrer apparatus 9 housing therein the dn~p object, constructed as described above. after being dropped by tfre transport airplane. Gne or a plurality of weights is provided at predety mined (ocatia~ns inside the container main body ~i , acxording to need, for example at tfie upper end section, yr in the middle of the main k~ody 1. As a result, it becomes possible to adjust the weight, center of grauity, and momer~ of inertia of the entire container main body 7 hoc~sing therein the drop object to conform the dropping property of the transport airplane. In the oe~se where the plumb i~ob 5 is unnecessary, depend;ng on the ~weEgfit or center of gravity or the like of the entire container main body 1 housing therein the drop object, the plumb bob 5 needs not be provided.
Next, the use and operation of the container apparatus 8 oonatructed in this manner are described with reference to FIG. 1 to FIG. 3. First, in FIG, t and FIG. 2, the lower ends of the main body members 1 a and 1 b which are fiormed by just dividing the container main body 1 vertically into two are placed in a state in which they can tie opened, these lower ends of the main body members 1 a and 1 b are opened oufv!vards to the left acrd right, and the drop object whieh exhibits the function xs. the point marker or the hydrographic conditions mea.$uring device or the like, is housed in the container main body 1.
Subsequently, the lower ends of he main body members 1 a and 1 b are closed, acrd as shown in FIG. 'I and FIG. 2, the tape memf~er serving as the main body coupling means 2 is wound around thg outer peripheral surface of the opposite end section, thereby coupling the lower ends of the main body members 1 a and 1 b of the container main body 1 and preventing it from b~ing opened. At this time, as si,ovm iv F'fG. 2, tMe cord type merrcber searing as the main body releasing means ~
is arranged in a to p shape in a matter to loop around the outside and the inside of the tape member (2j in a loop, and is connected to the automatic extending cable 4 at the upper end poirGon thereof. The drop objedc is thereby housed in the container main body 1.
Next, the container apparatus 9 housing therein the drop object as described aborre, is loaded onto the aircraft serving as the transport airplane. The air~aft c~,nying the container apparatus 9 housing lt~e drop object then flies to a position a predetermined land area or sea area, and upon reaching a point of salvage or search practice, for example, an operator on the aircraft: hooks the ring 8~ of the autiomatic extending cable 4 onto a part of the sirrraft, opens a door or hatnh and , drops tire entire container apparatus 9 into the air. Tha~ container apparatus housing therein the drop object then falls freel~l, and felto~rvs a subsTatttially uniform trajectory after being drppped by the transport airplane, due to the cylindrical container shape and trte plumb bobs 5 and the (ifce°
In this state, the automatic extending cable 4, the ring 8 of x~rhhich is hooked onto the part of the aircraft, gxtgnds automaticaJty to a predetermined length, and upon reaching the foil Length; the auts~matic extending cable 4 pulls the cord type member (3'), thereby cutting the tape mernE~er 2 with the cord type , member (3j.
Consequently, the coupling at the opposite end section of the container main body 1 is released, and as shown in FtG: 3, an ait pressure during the falling causes ~ehe main body memt7ers ~ a and 1 b tv rotate about the hinge B tv be opened, as indicated by the arrows A and B. As a result, a drop object 10 housed in the corrt-airrer main body 1 is released, and then falls as indicated by the arrornr C.
Subsequently, the drop object 1o tells freely, or felts using a paracf-~uce or the like, and (ands on the land or water surtace of the predeterm(ned (and area or eea area, to exhibit the function as thg point marker or the hydrographie oonditi4ns me4suring device, or the like.
FIGS. 4 is an explanatory diagram showing another embodiment of the main body coupling means 2 and ifie main body releasing means 3. F1C,. 4 shotrvs a configuration of the bottom face of the container main body 1 shown in FtG. ~f , and in this embodiment; as a m in body reupiing means 2', there is used a thread type member which draws together and ties the main body members 1 a and 1 b trvhich a~
formed by just di~riding the containQr vertically into ~t~rvo, and which (s melted to be broken at a predetermined heating temperature, and as a main body releesin~
means 3', there is used a heating member which in activated by oho extension of the autorrratic extending cable 4, and melts to brake the main body coup((ng means a°.
A strong line used in fishing known as °'silk guts can be used for the thread type member serving as the main body coupling means 2°. Furthermote, opposing hooks 't 1 which face inward are mounted et 'the lower ends of the main body members 't a and 1 b of the container main body 1, and the thread type member (2'~ is wound fyetween these hooks 11 a plurality of times, and ~gi~tened so as ~to draw the main body members 1 a and 1 b together. Moreover, it is possible to adjust a distance bet~reen the hooks t 1 by fuming screws 12 used to mourn the hooks 11, by a screwd~rsrer, therjeby adjusting the tightness of this tf~read type member (2~.
Furthermore, provided 'ti~at thethread type rrrember (2~ is melted to be broken at the pre;ier~m,ined heating r~mperature, the thread Type member (2') is not limited to the silk gut mentioned above, and a line made of a synthetic fiber or a metal or the lilac may also be used: Accordingly, it: ig possible with a simple material. to couple the other ends at the opposite end section of tl~ oontafner maim body 1 so as to prevent them from being decoupled.
A nichroms Wire having a suitable resistance can be used as the heating member serving as the main body releasing means ~', for example. Then, the heating member t~') is wound onto a part of the thread type member (2') wound between the hootcs 11, as shown in FtCi. 4, and power is supplied tQ this heating member (3') from a battery (not shown in the figure] via a lead wire 13. In FIG. 4, reference nurnera! 14 denotes a hook cover provided In the vicinity of the hooks 11, which also serves as a bottom plate of the container main body ~
FIG. 5 is a circuit diagra:rn showing a heating control circuit for heating the heeding member serving as the main body releasing means 3'. This heating control circuit comprises a battery E, a heating member (3~ formed from nichrome wire, a time oontroffer 15, s main switch 16, a test switch 17 for battery testing, and a battery test tamp (such es a light emitting diode) 1$:
The time controller 15 controls a period of time until the thread type member (,2'~ serving as the main body coupling means is fieated and melted to be broken by the heating member (3'), and cnmp~ris~es a resfsto~r which gives a predetermined delay time, and v~hich may be a variable resistor. Furthermore, the main switch 16 svvicches me ON/OFF of the power supply w the hea~ng member (3~ from the battery E, and a switching member thereof is acti~ra'ted by the exzensfon of the automatic extending cable 4 shown in FIC. 1 and FfC, 2, to tum the main switch i a Ot~/OFF. In other ~nrords, the main switch 15 is normally OFF, but turns ON by the extension of the automatic extending cable ~4 attached o the transport airplane.
~lexct is a ~desortption of the operations of the main body coupling means ~' ~d the main body releasing means 3' shown in FIG. 4 and FfG. 5.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 is a perspective view showing an embodiment of a container $pparatus for an object t~o be dropped (hereunder referred to as a drop object) according to the a present icrrention. This ao~ainer apparatus houses therein a drop object ~rrhich functions as a paint marker or s hydrographic conditions measuring device or the like, to be dapped by a ~~ansport airplane such as an e~ircraft dying in the air to a water surface of sea, Iake or the like, or fro land or the like, The container apparatus comprises a container main body 't, main body coupling means 2, main body releasing means 3, an automatic extending cable 4, and a plumb bob 5.
In FtG. ~ , the ~ntainer main body 1 houses therein a drop object which exhibits a predeterrt~ined function, to be dropped by the xransport airplane 'not shown in the frgures), and is formed from thick paper, plastic or metal or the like in the st~rape of a ~riinder with a circular or polygons! cross~sectioh. The container main body i is just di~ded vertically into two portions (1 a and 7 b), and as shown in FIG, 3, one ends (upper ends) of the t~rvo portions at one end section of the container main body 1 are connected by a hinge 6 and the other ends (lower ends) at the apposite end s~tion of the container main body 1 are able to be deooupled from each other to both sides, as indicated by the arrows A and B. Speciily, as shovm in FiC. 1; the shape of the c~ntainsr main body 1 is a circular cylinder witft an outer diameter of approximately 120mm and a total length of approximately 1 QOamm, for example;
and one of division lines 7 between the vertically divided main body members 1 a and 1 b is shown on the side wail of the container main body 1.
The main body coupling means 2 is provided at the opposite end section near the bottom of the container main body 1. This main body coupling means 2 couples the other ends of the two porlaons of the container main body 1 to prevQnt the other ends from being decoupled, and as an examples consists of a tape member wound around the outer peripheral surface of the opposite end section of the container main body 1. specifically. an adhesive tape with a width of approximately 100mm and a length of appro~cirna'tety 22bmm is wound around the outer peripheral surface of the apposite end section.of the container main body 1. ~rdingly, it is possible with a simple ntate~al to couple the other ends at the opposite end section Qf the container main body 7 to prevent the other ends firom being decoupted. This main body coupling means Z consisting of the tape member can bye cut with a card type member as described befnw.
The main body releasing means $ are attached to opposite side waif portions of the container main body 1. The main body releasing means 3 release the coupling " CA 02424446 2003-04-04 of the main body coupling means 2, thereby deaoupling fhe other ends at the opposite end section of the container main body 1, and as art ex2rr~ple, consists of a cord type memE~er,v~hich is connected to the automatic extending cable ~, described below to cut the tape member serving as the main ~dy coupling means 2 by the e~ctensiQn of the aufomatic extending cable ~4. Specifically; a type of line known as °'sflken gut", ~nrhich is a strong fine used in fishing, can be used for the cord type member serving,as the main body releasing means 3. This cord type member (3'j is not limited do the silken gut mentioned above, and a line made of ynthetic fibers or metal or the like may also ire used. By using such members, it is possible with a simple construction to retea$e the coupling by the main body coupling means 2, thereby decoupling the other ends at the opposite end section of the carrtainer main body '( .
