Description of the invention: [Technical field to which the invention pertains] The present invention relates to a binder. [Prior Art] Previously, there have been a large number of binders which are provided with a plurality of fixing rings on one side of one of the elongated plastic substrates, and are disposed on the other side by the shaft The member is supported by a plurality of movable rings that are rotatable and freely openable and closable with the fixed ring, and a sheet (10) in which the insertion holes of the respective rings corresponding to the respective rings are provided in advance are detachably fitted in the rings. The above-mentioned binders have the following binders and the like, as described in Japanese Patent No. 3749893 (Patent Document No.), which is attached to Fig. 24 of the present specification and No. 4〇〇 in Fig. 25, and is attached to the shaft member. The human metal wire _ / 08' is used to twist the first half ring element 404 which is self-fixed by the half ring element 402 of the 35-shaped engagement means 4〇5. When the hand & operative is disengaged, the shaft member 4 () 6 is rotated to drive the opening action. K Le% However, in the binder thus constructed, in addition to the different elastic components such as the meal force or length, the armor must be prepared for the more complicated structural parts of the binder. And the base does not detach from the soil material to assemble the above-mentioned elastic cyanine member and does not damage the effect of the spring. Therefore, the manufacturing time is too low. The following door 1 g * 4 has a problem in terms of cost, and also causes a problem, that is, in order to improve the coil b Phase gold eyebrows, ht > red-μ The durability of the related components and the use of the friend's attribute of the shaft member will cause heavy rust. Also, the metal spring waste 200909236 discards the labor and time of the classification. Moreover, the technology of No. 3749983 exists in the case of the Shangjiang I patent (4) w. When the long right is opened, the half ring is suddenly opened, causing the loosened loose leaf. On the other hand, as described in the special paragraph (0024) of Japanese Patent Laid-Open No. 407672 (Patent Document 2), there is a binder which has a low protrusion on the outer circumference of the shaft body. The inner circumference of the sleeve portion "the sliding portion corresponding to the low protrusion corresponding to the low protrusion, and the rotation action of the low protrusion has a moderate feeling by the contact action of the low protrusion: the low two is only used to stop the rotation of the shaft body The brake is used - 〇〇 32) "The load can be taken out or placed in a paper at a given position (the paragraph method S does not have sufficient braking force to be stationary at a predetermined position, and no/can replace the opening and closing action of the promotion ring) In the case of the above-mentioned Japanese Patent No. 3775217 (Patent Document 3) (0022), it is described that the ring is prevented from falling off when the half ring element is closed. The direction of the direction = the resilience force causes the fishing-shaped engagement means to be locked, and on the other hand, the resilience force promotes the opening operation when the hook-shaped engagement means is opened by twisting. [Patent Document 1] 374% of the patent Publication No. 93 [Patent Document 2] The specification of the patent No. 34,767, [patent document 3], the specification of the patent No. 3775217, the content of the invention, the technique of the document 1 must use a metal spring, which is a component and time for disposal, and a movable ring When opened, according to the technique of Patent Document No. 200909236, the ring-long sub-substantial opening is greatly opened during the opening operation of the ring, so there is a problem that the loose-leaf accidentally falls off. On the other hand, the technique of Patent Document 2 is due to the effect of low protrusion. In the middle of the half-length, there is a very small simple, < gap, which can be taken out or placed in the loose-leaf, but the elasticity of the shaft is not utilized but the friction is used, so the stability at the position is poor. 3 technology, miscellaneous 7 Although it can take out or put a loose leaf in a small gap, but there is no means to stop the movable ring with a small opening, so there is a problem that the opening angle is unstable and the loose leaf is scattered. Therefore, the object of the present invention is to provide a binder to solve the above problems of the first moon 丨 product, and to witness the first one and the 5 liter folder is made of plastic. The movable ring is opened in two stages, ^ to prevent the loosening of the loose leaf, and the insertion of a small number of loose-leaf pages + the opening of the younger brother, and the widening of the insertable calendar According to the present invention, there is provided a folder having a problem of the prior art as described above, which has the following configuration. That is, the present invention provides a binder 10, 100 including a plate-like base body 16' is disposed along the second solid (four) 14; and the support shaft 22 is further provided with a shaft, and the second side edge portion 18 of the '/σ base body is disposed in the base shaft The groove 20 is freely bendable and rotatable, and is rotatably supported by the bearing portion 24 of the base body. The two portions on the side of the portion are exposed to the external search portion 28' through the notch portion 26 of the base portion. Two movable rings 3G and a movable ring 3G which are formed in a closed loop are formed on the outer circumference of each large diameter portion, and the front end portion is respectively engaged with the elastic deformation of the support shaft and the movable ring to be engaged with each other. The hook-shaped engaging means 32, the support shaft 22 has a circumference The front cams 34, 34, 104 and the rear cams %, 136, 1〇2 are protruded in the radial direction, and the base 16 has the i-th locking portions 40, 140, 108 of the front cam contact when the support shaft 22 rotates. And the second locking portions 42, 142, and 106 that are in contact with the rear cam, when the movable ring is engaged with the fixed ring, the front cams 34, 134, and 104 are in contact with each other! The locking portions 4〇, 140, 108 generate a reaction force with the torsion Μ and the first f 帛1 reaction force on the fulcrum 22, and the 胄i reaction force acts when the fixed ring and the movable ring are in a closed loop state. In the direction in which the movable ring is opened, the engagement force between the two hook-shaped engaging means is enhanced. On the other hand, after the engagement of the two hook-shaped engaging means is released, the first reaction force causes the movable ring to automatically open from the fixed ring. , △ in the movable ring of the above two hook-shaped engagement means has been separated! When the rear cams 36, 136, and 1 are engaged with the second locking portions 42, 142, and 106, the further opening of the movable ring is restricted to form between the movable ring end and the front end of the fixed ring. The gap between the flaps can be taken out or placed in the gap of the flap, and when the second loop of the support shaft 22 is applied to the movable ring, the force generated in the opening direction of the reaction force is as follows: 136, 102 overcome the second locking portion 4 幵 > I l 丄 、 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 〇〇 , , , , , , , , , , , 、 、 、 、 、 、 、 °卩 Further separation. Thus, according to the present invention, the open state of the second-order 200909236 segment can be realized. In the middle of the page, in order to open the ring from the closed state, the two fishing-shaped snapping means are separated from each other in the direction of pushing the dust. On the outer side of the axis of the handgrip, Jiang _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ . % is pushed to the other side so that the two cams are automatically turned into the first position because the front cam is subjected to the first action from the j-th locking portion, so that the position of the portion can be maintained and the second cam is difficult to contact the second cam. It is in the first open state. In order to make the movable ring burst, the upper open/open state leads to the second J shape in the open direction. Does the force move the force in the opening direction beyond the 箆? When β is pressed from m to the right, the cam will move beyond the second card I* ϋβ A in the open state. (4) The second locking portion is in the second aspect: when the ring is to be closed, the finger is pushed to the second: after the self-card opening state is closed with respect to the fixing ring, the front cam: the second pressure I:: And the first reaction force generated, which can be pressed, can be pressed to make the hook-like engagement means & In the lower state, the locking action can be maintained to some extent, and the force is applied by hand: d * is closed from the second open state to the first open state, and the movable portion of the stop 2 is pushed in the direction of the fixed ring, the rear cam When the second bayonet is pressed against the reaction force generated by the second bayonet (not necessarily the same as the second counter 200909236), the rear cam passes over the second locking portion, and the movable ring is in the first open state. In a preferred embodiment, the bearing portion 24 is provided at both end portions of the support shaft support groove 20, and the support shaft support groove 2 has a sufficient width to allow the support shaft 22 to be sufficiently curved so that the rear cam can be The operation of the second locking portion is performed. By adjusting the height of the rear cam protruding from the radial direction of the fulcrum, the minimum opening degree of the movable ring with respect to the fixed ring in the second open state can be arbitrarily set. In another embodiment, the base body includes at least one of the support shaft fall prevention projections 48 projecting from the lower side of the support shaft 22 in the support shaft support groove 2'. The intention is to always support the fulcrum without depending on the angle of rotation of the fulcrum. Since the fulcrum fall prevention projection must be integrally formed at the time of molding, it is formed in the axial direction of the bearing portion and/or the axial direction of the two large diameter portions so that the fulcrum can be barely fitted. In still another embodiment, the first locking portion 4A and the second locking portion 42 are formed on the side of the groove 2〇 side of the side wall portion 44 of the second side edge portion 18 of the base body, and the side wall portion 44 The inner side portion constitutes the i-th locking portion 4, and the inner surface portion extending upward from the inner edge end of the inner side portion of the side wall portion 44 constitutes the second locking portion 42 (described in FIGS. 3 to 7) . In the other embodiment, the first locking portion 14A and the second locking portion 142 are formed on the surface of the reinforcing rib 46 provided on the inner side of the groove 20, and the inner portion of the reinforcing rib 46 constitutes the first locking portion. In the portion 14A, the inner surface portion extending downward from the edge end of the groove portion side of the reinforcing rib 46 constitutes the second locking portion 142 (described in Figs. 8 to 11). 10 200909236 _ The front cam 104 is disposed on both sides of the intermediate position of the fulcrum and close to each position of the large diameter portion 28, and the intermediate position of the rear cam 1 〇 2 in the fulcrum is in the circle of the fulcrum; It is provided in a state of being separated from the front cam described above (described in FIGS. 13 to 22). In the present invention, it is preferable that the binder is entirely made of plastic. The leaflet of the present invention is composed of two parts and can be easily separated, thereby facilitating resource recovery. As a general rule, the support shaft 22 and the movable ring 3 are made of a highly resilient tree, and the base body is made of a resin having high shape stability and high rigidity. The movable ring 3G is made of polycarbonate, and the base body is made of interesting resin. The effect of the moon has been condensed to some extent above, and it can not only solve the problem of manufacturing time and cost related to the previous product, but also effectively solve the problems of weight correlation, birth record, classification, etc. It can provide a spring force that can effectively promote the engagement state of the semi-ring element and the opening and closing action, and then the 'movable ring can be opened in two stages, and can provide a full-plastic open-sheet binder that is opened in two stages, even if the leaflet is inserted or removed. The file operation: The force generated by the accidental page will not be easily separated, but will stop at the first open state. [Embodiment] A third embodiment of the present invention will be described with reference to Figs. 1 to 7 . =1 The whole of the binder of the present invention is indicated by the number 1G.

The elastic deformation of the movable member 30 is engaged with each other to maintain the closed loop state. One of the hook-shaped engagement means is a hook, and the other hook-shaped engagement means is a hook hole. Embodiment 1 The support shaft 22 of the binder of the first embodiment has a triangular convex portion 38 at a position intermediate the longitudinal direction thereof, and the triangular cam 38 has a cam 34 and is separated in the circumferential direction and extends in the radial direction. Rear cam % (the front is "front" when the movable ring 30 is opened, and the latter is "rear"). On the other hand, the base 16 has a configuration in which the front cam Μ and the rear cam 36 are rotated when the fulcrum 22 is rotated. The i-th locking portion Μ and the second locking portion 42 that are in contact with each other at the movable position. The front cam 34 and the rear cam 36 are provided at an intermediate position in the longitudinal direction of the support shaft 22, the first locking portion 4G and the second locking portion. The portion 42 is formed on the second side edge portion 18 of the base body 16, for example, the side wall portion protruding as shown in FIG. 12: 12 200909236 The inner side of the bucket 〜w only constitutes the first locking portion 40 40, from the inner side portion The inner surface portion of the side wall portion extending upward from the edge end constitutes the second locking portion 42. When the movable ring 30 and the fixed ring 14 are engaged with each other, the front cam (four) is in contact with the position when it is closed as shown in FIG. 4! The locking portion 4〇. In the white (four) state, the movable ring 3 is moved into the step (four) when the I: part The card is combined with each other...the card is combined with each other as shown in Fig. 5 =:, day ''The support shaft 22 to be reluctantly rotated is bent from the original central axis to the arrow L:: shown in FIG. 5 via the cam portion of the front cam 22 The predetermined distance is 1, so the reaction force of the torsion is dispersed in the fulcrum by the reaction force of the two forces. By:: the force of the reluctance is moderated, and the torsion can be improved (hereinafter, referred to as the "threshold! reaction force") The effectiveness of the action.

In this state, the degree of opening and closing of the leaflet is slightly opened between the fixing ring U and the movable ring 30. Further, if it is specified that the front cam 34 and the i-th locking portion 4 are simultaneously contacted, The position and the position where the rear cam 36 is in contact with the inner surface of the side wall portion 44, that is, the second locking portion 42. The first open state of the movable ring can be a fixed position. Thereafter, the movable ring 3 is opened with a finger. Thereafter, the rear cam 36 and the support shaft 22- are rotated, and the support shaft 22 is bent at a predetermined distance U in the direction indicated by the arrow LL in FIG. 6 and slides on the second locking portion 42, with the reaction caused by the bending. The force (hereinafter referred to as the "second reaction force") pushes the second locking portion 42. During this period, since the second reaction force is a spring force that can be rotated in the closing direction, the second bad element immediately returns to the state shown in Fig. 4 after the hand is released. Then, as shown in Fig. 6, when the top of the rear cam % comes into contact with the second locking portion 42, the second reaction force does not exert the rotational force at this position. Then, after the force of the second reaction force exceeding the opening direction is reluctantly applied to the movable jaw 3 with the finger, the top of the rear cam 36 exceeds the second locking portion 42, and the movable ring 30 is as shown in FIG. 7a and FIG. Does not move to the second open state. Furthermore, the round: the angle of the front and rear of the 2 card can depend on the radius of the rear cam! Arbitrarily set the size. The reason why the angle can be set in this way is that the central portion of the 'the center portion is free from the support of the support shaft, and is curved from the large towel. In this state, the leaflet can be inserted into the ring in a state in which a plurality of sheets are overlapped.

The same applies to the above embodiments. As described above, according to the present invention, when the movable ring is opened from the closed state, the intermediate 胄i open state and the second open state of the second open state can be performed, so that the two can be utilized. Any of the states - open state. Further, since there is no such thing as the patent document 1, the sub-ring is not smashed. Khan Embodiment 2 In Fig. 8 to Fig. 2, a second embodiment of the present invention is exemplified. In the second embodiment, the front cam 134 and the rear cam 136 are formed in the opposite direction of the support shaft 22 from the first embodiment. Further, the first locking portion uo and the second locking portion 142' are composed of the second side edge portion 18 of the base body 16 and the reinforcing ribs 46 that are closer to the inner side than the support shaft 22, and are formed from the reinforcing ribs. The inner side portion observed on the groove side constitutes the i-th locking portion 14A, and the inner surface portion from which the edge portion of the inner side portion is extendable constitutes the second locking portion M2. Similarly to the first embodiment, when the movable ring 3A and the fixed ring 14 are engaged with each other, the front cam i34 contacts the i-th locking portion H0 at a position before closing as shown in Fig. 8 . When the movable ring 3 is further rotated from this state and the engaging means 32 of the respective distal end portions are engaged with each other in the closed loop state shown in FIG. 9, the support shaft 22 to be reluctantly rotated is connected to the first by the front cam 134. The locking portion 40 applies a pressing force and is twisted with a reaction force. At the same time, the cam portion of the fulcrum 22 is bent in the direction of the arrow L shown in Fig. 9 by a predetermined distance 15 200909236 from i', and the twist is reversely dispersed. Thereby, the force which is reluctant with the wide portion as the reaction force of the bending is obtained in the same manner as in the first embodiment, and the structural effect on the fulcrum 2216 is added. i and improve the first reaction force of the twisting 1 brother reaction 1 々 牵 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 々 The direction of the state, so that the ring elements are stronger and not swaying, and the closed-loop state can be stably maintained even if the closed-loop state is subjected to a certain degree of external force. ... In other respects, the shovel 1 pushes each other at the same time. Similarly, by using the thumb and the index finger to move the % 30, 3 〇, etc., the card on the movable ring side 32 is detached from the engaging means 32 on the side of the fixed ring side, and the movable ring 3 〇 ^ 卩 1 described the reaction force On the other hand, the position in which the second locking portion 40 is in contact with the position of the slanting portion...the second locking portion 42 is not stopped in the first open state. The extent to which the insertable leaflet is opened slightly between the retaining ring 14 and the movable ring 30. Thereafter, after the movable ring 30 is further opened, the rear cam 136 and the support shaft 22 are rotated 'to make the support shaft 22 Juice diagram 0 arrow LL is not in the direction of the bend: Liu In the state of the second locking member, the second reaction force is pressed against the second locking member 142. During this period, the second reaction force acts to close the movable ring 3 in the closing direction. The action of the yellowing force 'so the movable ring 3 () immediately after releasing the hand is immediately in the state shown in Fig. 8. A to 16 200909236 Then, as shown in Fig. 10, when the top of the rear cam 136 is in contact with the second locking portion 142 At this position, the second reaction force no longer exerts the rotational force. Then, after the force of the second reaction force exceeding the opening direction is reluctantly applied to the movable ring 3 with the finger, the top of the rear cam 136 exceeds the The locking portion 142 is moved to the second open state as shown in Fig. 1A. Each of the above-described embodiments of the present invention further has the following pivoting prevention projections. As shown in Figs. 1 and 2, the base 16 is supported. The shaft support groove 2A is provided at a position away from each side of the triangular cam 38 of the support shaft 22, and a position of each of the bearings 24 is provided with a first branch protruding toward the inner side of the support shaft support groove 2 The shaft fall prevention protrusion 48 is disposed at each side away from the triangular cam 38 The first fulcrum fall prevention protrusions 48 and the ith fulcrum fall prevention protrusions 48 provided at the positions of the respective bearing cymbals 24 are disposed opposite to each other but can be arranged in the same direction. Since the diameter of the branch #22 is far The diameter of the support shaft 20 is smaller than that of the support shaft 20. Therefore, if the support shaft 22 is pushed into the support shaft 20, the first s shaft fall prevention projection 48 is elastically deformed from the opposite wall. The support shaft 48 is supported by the protrusion 48 and can be prevented from falling off. Further, the j-th shaft fall prevention protrusion 5G can be provided in each large diameter portion 突 of the support shaft 22 of the movable ring 3〇. In the range of the rotation of the movable ring, the portion in the circumferential direction of the lower side is formed into an arc shape. The second support shaft fall prevention protrusion & 5' reduces the distance between the support shaft 22 and the splint backing paper (not shown) at the position of the large diameter portion 28 when the loose leaf is attached to the backing paper of the splint. Therefore, even if the movable ring 306 is pushed in the range of the rotation, the pressure is pushed to the side of the splint side, and the support shaft 22 does not fall off. Further, 'as shown in Fig. 12 and Fig. 23, the long-circle U knows' can also be used for the μ-supporting off-prevention protrusions 52, 1 by the third 仂罟6* and the side of each large-diameter portion 28. The branching prevention protrusion 52 is fixed to the support shaft 52, and is fixed to the inner wall 54 of the support shaft support groove 2 on the support shaft 22 before the support shaft is disengaged, and 14 is fixed to cause the support shaft to fall off. Preventive effect, I double stay, and the bad cause of the support shaft 22 with the reaction force (hereinafter, referred to as the twist of the additional addendum), the knife is used for a long time, and the reaction force is also present in the π + „ There is a function that when the movable ring 30 and the solid ring 14 are in the closed loop state, the first reaction force that has been clarified is promoted by the mouth—and acts on the movable ring 3〇 to strengthen the closed state. Furthermore, the inner wall 54 which is the contact of the protrusion of the 5th axis of the 5th brother can be inserted into the support shaft 2〇 as shown in FIG. The formed bearing portion 56 is provided. Embodiment 3 3 Embodiments The following description of the present invention will be made with reference to Figs. 13 to 22 .

The effect of the slight pulling force is 0 ^, the moving clothes 30 is in the opening direction 'and acts on the direction of the engagement state of the reinforcing engaging means 32 (consisting of the hook holes formed by 19 and 200909236), thereby making the ring elements stronger. The grounds are locked to each other without shaking, and the closed loop state can be stably maintained even if the force is applied to a certain extent in the closed loop state. On the other hand, in the same manner as the embodiment of Fig. 1, the movable ring 30, 30 is bent in the direction of the arrow at the same time by the finger, so that the snap ring 3 of the engaging means 3 is immediately rebounded and automatically opened by the above-mentioned 丨& Further, the position of the cam 102 in contact with the i-th locking portion 1A8 by the cam 104 and the position where the second + I Μ 1 can be brought into contact with i can be turned on and off (see Fig. 19). In this state, the degree of opening and insertion of the leaflet is smallly opened between the fixing ring 14 and the movable member. With the branch = one? The movable ring 3 is pushed in; the opening and closing 'turns the support shaft 22 to a predetermined distance in the direction indicated by the arrow LL in FIG. 20, and the second lock is bent and the whip is produced. When the second locking portion (hereinafter referred to as the second reaction force) is pushed during this period, the second reaction force acts as a spring force that can be rotated in the closing direction, so that the hand is released. The garment element is automatically restored to the Fig. 18 or Fig. 17 and then 'the rear cam is as shown in Fig. 20: after the contact, the second latching portion is actuated at the position. Then, with the finger pair Movable ring 3〇: Strong ^ exerts the force of the second reaction force in the direction of the rotational force, the rear cam == over open loop locking portion (10), and the movable ring 30 exceeds the second open state as shown in the top of FIG. 21, ::2 Furthermore, the rear cam moves over the second card 2 and 2 to the second (depending on the radius of the slant #102). The angle can be arbitrarily set according to the dog size. For example, 20 200909236 The central portion of the fulcrum is free from the support of the fulcrum support groove, so that it can be bent greatly. In this state, the leaflet can be inserted and removed into the ring in a state in which a plurality of sheets are overlapped. As shown in Fig. 15, the position of each bearing portion and the axis of the two major diameter portions are provided in the support shaft groove 20 of the base body 16. The position of the direction ^ is toward the inside of the support shaft support groove 20, and the difference y1 & 1 protrudes toward the inner side of the support shaft 22, and the ith branch shaft fall prevention protrusion < 48. In this example, the first fulcrum is detached. The protrusions are prevented from being arranged to face each other but can also be arranged opposite to each other. Since the fulcrum 22 is much smaller than the diameter of the fulcrum support groove 2 ', the fulcrum 22 is reluctantly pushed into the fulcrum support groove 2 〇 Then, the first fulcrum fall prevention projection 48 and the opposing wall are elastically deformed. The fulcrum is easily fitted over the fulcrum support groove 20 and is prevented from falling off by the projections 48. Further, the first embodiment帛2 Embodiments and the binders of the third embodiment are all made of plastics. For example, the branch #22 is formed of a resilient resin such as a strong side and elastic, and other members are made of high rigidity such as Nasuozhi. The resin with high stability is formed. Further, the action of the closing direction of the movable ring and the embodiment 丨The actions described in the above are substantially the same. If the actions of the above-described embodiments 丨 to 3 are summarized, the following is as follows: In order to open the ring from the closed state, first use the finger to move the movable ring before: the two hook-shaped engaging means are mutually Pushing in the direction of disengagement. For example, as shown in Fig. 2, the hook-shaped engaging means for the fixing ring is disposed on the outer side in the axial direction of the binder, and the hook-shaped engaging means for the movable ring is set on the axis of the loose leaf. The inner side of the direction pushes the two movable rings in the direction of the other side, so that the movable ring fishing 21 200909236 card is detached from the μ-locking means of the ring. The moving self/cam receives the first reaction force from the first locking portion. % automatically becomes the first open) force, so can

The wheel passes over the "locking portion and moves to the second side. On the one hand, when the ring is to be closed, the movable ring is opened by the hand to open the state, and the movable ring is caused by the first locking portion; =, the fixed ring pushes 'to make the hook-like snapping means to lock each other and has the ith reaction force in the movable loop state, so the card Γ::= off: the front end has no sway, and Thus, the waiter is in a state of being stopped. Under certain degrees of external force, the card can be maintained, and the second open state is closed to the i-th open state: the finger is used to push the movable ring toward the fixed ring, the rear cam and the second card The stopper is engaged to counteract the reaction force generated (not necessarily the same as the second reaction force), and the money is pushed forward, and the rear cam passes the second locking portion to bring the movable ring into the first open state. The invention has been described with reference to the embodiments, but it should be understood that various modifications may be made within the scope of the invention.
