Abstract
This system is a flexible bags mounting and dispensing system which has two equal length substantially parallel arms hingedly mounted together at their front end by a cross member. A flexible bag can be mounted to the arms through tubes or pipings provided at the edge portion of its opening. The bag can be opened for filling operation by pulling the middle section of the arms away from each other, and the mounted bag can be kept in a closed condition by operating the middle section of the arms back to their substantially parallel condition.
Description
~ ~3~
This invention relates to a bags mounting and dispensing system, and more particularly relates to a mounting and dis-pensing system for flexible bags such as plastic bags used for containing groceries, garbage and the like.
Flexible bags have a wide variety of uses. Nor-mally the bags are provided in a stack in a folded manner or in a tied bundle so that a bag can be removed from the stack or bundle one at a time. Alternatively, the bags are supplied in a continuous roll with a score line provided between suc-cessive bags such that one bag at a time can be pulled off from the roll for use. In use, the bag must be expanded and its opening must be maintained în an opened state so as to facilitate its filling. For relatively small size bags such as groceries bags a simple bracket can be used to maintain the bag in an opened state for filling it with groceries. However, for larger bags such as a garbage bag or storage bag, it has been problematic to provide a simple bracket to maîntain it in the opened position for filling purposes. Furthermore, the bracket can not be used for maintaining the bag also in a closed position for storage purposes such that the material stored in the bag is safely sealed therein. Also, it has been always difficult for a user in finding the bag of a correct size to fit properly in the bracket or container; more commonly people would use bags from their everyday shopping, with some being too small, or too big, or very thin, or not strong enough to serve the purpose. And with the environment being at risk, there is a definite need for the use of only recyclable and biodegradable bags, which is not normally the case for shopping bags. Yet another problem with conventional bags is in closing the bag when it is filled and it is 3~
required to be replaced. It is extremely difficult to tie the top edges of a filled bag or to use a string to wrap around the bag since there is not enough bag material left unfilled to be pulled together. This is because people normally have the tendency of not replacing the filled bag unless it is very full, thus not leaving any room at the top of the bag for tying. With all of the above mentioned issues in mind, the system disclosed herein was developed, solving all the problems of finding the correct bag, mounting it, maintaining it in an open state, temporarily closing the opening whenever it is desirable, closing the bag to be removed, tying the bag,and simultaneously finding a replacement bag after the filled bag is removed.
It is a prîncipal object of the present invention to provide a mounting and dispensing system which greatly facilitates the mounting of a flexible bag and it may be operative for maintaining a flexible bag in the opened position for filling operation as well as in a closed position for storage purposes and in the case of storing a material with obnoxious odour, the odour will be inhibited from emitting into the atmosphere.
It is another object of the present invention to provide a mounting and dispensing system which greatly facilitates the closîng or tying of a filled bag.
It is another object of the present invention to provide a mounting and dispensing system which readily provides a plurality of bags for easy access for use, and providing a continuous supply of bags.
It is another object of the present invention to provide a mounting and dispensing system which readily provides a ~0s35~
plurality of bags that are recyclable and bio-degradable.
It is another object of the present învention to provide a mounting and dispensing system which readîly provides a replacement bag that is already mounted and ready to be used as soon as the current bag is removed.
It is another object of the present invention to provide a mounting and dispensing system which serves as a convenient mounting means for a plurality of flexible bags for easy access for use.
It is another object of the present invention to provide a mounting and dispensing system for flexible plastic bags which is simple in structure and easy to operate.
The principal requirement of the mounting and dispensing system is to have arms that are substantially parallel to each other in the closed position to facilitate the mounting and removal of a flexible bag on and along the arms, as well as operative sideways outwardly away from each other in their middle portion to maintain a flexible bag in the opened position for filling operation.
In an exemplary embodiment, the flexible bags mounting and dispensing system primarily comprises a right articulated arm member and a left articulated arm member mutually parallel to each other and are equal in length. Each of the articulated arm member has three section members, namely a front section member, a middle section member and a rear section member. The front section member has a rear end hingedly coupled to the front end of the middle section member. The other end of the middle section member is hingedly coupled to the front end of the rear section member. The rear end portion of the rear section member has a free end portion operative for mounting - ,~ o~s~
the system in a cantilever manner on a vertical mounting wall.
The flexible bags have mounting pipings or loops provided on their opening edge portion such that the bags can be threadingly mounted on the rear section member of the articulated arms. A bag can be pulled over the front section member and the middle section member for use.
The system is set up in such a way that when the arms are pushed towards each other, the system becomes in a closed state, where the arms form two parallel lines juxtaposed to each other. However, when the arms are pulled away from each other, they are no longer in parallel, and the system becomes an open state. The basic idea is that when the arms are in parallel, i.e., the system is in a closed state, a bag mounted on the arms through pipings provided on its opening edge portion can be pulled along the arms all the way until the end of the arms, thus providing an empty bag in a closed state mounted on the arms. With this system, it is therefore extremely easy to mount a bag onto the arms since all that is required is to slide the bag along the arms. Also, the problem of finding the correct type and size of bag to use is eliminated since the bags are readily available. For opening the bag in use, the middle portion of the arms are simply pulled away from each other or exerting a pushing force axially at their front ends. The expansion of the arms will cause the bag to open and to be ready for use. Whenever the bag is not being used, it can be !cept closed by simply pushing the arms towards each other, hence the parallel arms maintain the bag securely closed to protect its contents. Whenever the bag is filled or is required to be replaced, the arms are first operated to the parallel positions, then the filled bag -- ~ 0~35Z~) can be pulled along the parallel arms all the way untîl the pipings on îts opening edge are tîghtly squeezed. The system thus greatly facilitates the action of tying the filled bag.
After tying the bag, it can be removed by using a cutter provided at the end of the arms. As the filled bag is being pulled along the arms to be removed, the next bag is automatically pulled forwards onto the arms to become ready for use, since the bags are serially connected to each other.

l~ith reference to the drawings wherein like reference numerals indicate same parts in the several different views, the system of the present învention is shown in an exemplary embodiment which includes an articulated bracket 10 having two equal length articulated arms 11 and 12. The articulated arms 11 and 12 are normally positioned mutually parallel to each other and each comprises of three section members, namely, front section members 13, 14, middle section members 15, 16, and rear section members 17, 18 respectively. The front end of the front section members 13 and 14 are pivotally coupled together and preferably hingedly coupled to a short cross member 19 as best shown in Figures 2, 3 and 4. The rear end of the front section members 13 and 14 are respectively hingedly coupled to one end of the middle section rnembers 15 and 16 respectively to form pivotal operating joints 20 and 21. These joints preferably have a configuration similar to a tongue and groove joint in which a slot is formed at the end of one ~53gX) section while a tongue-like end extension section is formed in the other section. The extension section is pivotally fitted into the slot of the associated section and the two sect-ions are pivotally secured together by a pin 22. The other end of the middle section member 15 and 16 are respectively hingedly coupled to the front end of the rear section member 17 and 1~
with similar tongue and groove joints. The rear portion of the rear section memher 17 and 1~ are connected to a free end mounting section 23 which may be L-shaped as shown and operative for mounting the articulated bracket ln in a cantilever manner by being inserted removably into a sheath bracket provided on a mounting means such as a wall or a post.
The flexible bags for the present system have a reinfor-ced double layer edge portion around its opening forming tubings or pipings 24 and 25 along each half portion therein.
The bags may be joined together at their upper end portion such that the pipings 24 and 25 are continuous from bag to bag, so that the bags may be easily and simply mounted on the artlculated arms 11 and 12 by inserting the latter through the pipîngs 24 and 25 respectively and pulling the bags tight together to hang onto the rear section mernber therein. The side of each bag may also be connected to the si-de of the bas next to it by perforated lines. The perforated lines will make it easier to separate the bags from one another. The bags may be easily and simply mounted onto the articulated arms 11 and 12 by first disconnecting the bracket 10 from the mounting section 23, and then inserting the end of the rear section members 17 and 1,~ through the pipings 24 and 25 respectively and pulling the bags tishtly together to hang onto the rear section mernbers therein. The bracket 10 is then connected back ~tO53~
to the mountîng section 23 for mounting to the wall bracket.
When a bag needs to be used, the first bag from the front end of the rear section members is pulled along the artïculated arms to extend over the front and mîddle section members.
The articulated arms 11 and 12 normally maintain the opening of the bag for use in a closed condition. When it is required to fill the bag, the bag may be opened by pulling the operatlng joints 20 and 21 outwards away from each other so that the articulated arms 11 and 12 are extended in a diamond-shaped configuration as shown in Figure 3 to maintaîn the bag ln an opened condition. The bag may he closed again by simply returning the operating joints 20 and 21 towards each other until the articulated arms 11 and 12 are în the substantially parallel posLtîon again. Thus, the bag mounted on the articulated arms 11 and 12 may be used for temporary storage purposes until the bag is full then, if desired, it can he removed from the bracket. To remove a bag from the bracket, the bag is pulled towards the cross member 19 along the articulated arms all the way until the pipings on its top edge are squeezed around the front end arms of the front section members.
A tie 2~ may be provided on the bag such that it is operati~Te conveniently for tying the bag after ît top edges have been squeezed to close together.
Two spring-mounted severing cutters 27 and 28 are - provided at the front end of the front sectîons 13 and 14 as best shown in Figure 4. The cutters 27 and 28 may be operated ~ to sever the pipings or tubings 24 and 25 of the bag such that r the latter may be removed from the articulated arms 11 and 12 after it has been fllled and tied by the tie 26. The filled ~53~
1~
bag may then be removed by pullîng away along the perforated line from the next spared bag. Since the pipings 24 and 25 are continuous from bag to bag, whenever a bag is pulled towards the front of the bracket to he removed, a new bag is automatically pulled forward to replace it and it is already raounted on the bracket 1n a closed cond-Lt-on and is ready to be used as soon as the bracket is opened, as described above.
This operation may be repeated unt-Ll all the baos nounted on the rear section members are expended, at which point another group of bags may he mounted onto the rear section members as described above.
Alternat~vely, instead of rnounting the bags onto arms 17 and 18, the bags raay be supplled from a cont~nuous roll, also having mounting pipings or tubings provided in their openings with the bags serîally connected by an impression line one after another. The bags will be mounted onto the bracket 10 through the front end of the front sect-ion members 13 and 14.
Tlowever, ln this case, the cross meraber 19 will not be used.
In th1s conflguration, the rear portion of the rear section mernbers 17 and 18 may be extended and bent to form an L shape and to act as a stand by -itself. The bags -in thLs case may be pulled, after being filled, all the way along section members 17 and 1~ hor~zontally and then through the L-shaped portion.
Cutters may eîther be located at the horizontal part of the rear section rnembers 17 and 18, or at the vertical or slanted part of the rear section memhers 17 and 1~. Also, the rear sect-~on members 17 and 1~ may be made shorter or eliminated for certain applications, and the rear portion of the middle section members 15 and 16 may be used for mounting.
Alternatively, the bags may have perforated lines at the c~Q535aC) Il top edge therein so that in order to remove each bag from the arms, the bag may be pulled down and it will breal~ away from the mounting bracket alono the perlorated line. To further facilitate the removal of the bags from the arrns, instead of pipinos or tubings 24 and 25, the bags may be provided w-ith a plurality of mounting loops 29 as shown in F1gure 7 and the bags may be mounted onto the art1culated arms 11 and 12 with the loops 29. The loops may also be perforated at the top edge therein.
In a second embodiment as shown in Figures ~ and 9, the mounting braclcet 30 comprîses of two sets of parallel articulated arms namely an upper articulated arms 31 and a lower artLculated arm 3?. ~ach art-iculated arm has a construct1on similar to the articulated arms 11 and 12 as described above. The upper articulated ar-n 31 has a left art1culated arm 33 and a rigl-lt articu1ated arm 34. The lower articulated arm has a left articulated arm 35 and a right art1culated arm 3~. Three -inverted IJ-shaped coupling brackets 37, 3~, and 39 a~e provided at the front, middle and rear sections respectively of the upper left articulated arm 33, and three s1MLlar lnverted U-shaped coup1Lng brackets 40, 41 and 42 are provided at the front, mlddle anc~ rear sectlons respect1vely of ~he upper right artlculated arrn 34. Fach coupl1ng bracket has an inner leg IL and an outer leg OI.
extending respectively downwards from the upper articulated braclet 31 to locate 1n a spaced manner on the lnside and outside of the lower articulated arm 32. The coupling brac!~ets 37 through L2 wlll cause the upper and lower artLculated arms 31 and 32 to operate ~Ln unl<,on with each ot'ner, namely, when the upper articulated braclet 31 is -in the closed or opened ~?e~3~c~
IZ
condîtion selectively, the lower artîculated arm 32 will also correspondingly be in the closed or opened condition simultaneously as selected.
The free end of the lower articulated arm 35 and 36 may curve slightly downwards and be slightly pointed such that a bag 43 may be pulled from a roll 4L~ to mount onto the lower art~culated arms 35 and 36 simîlar to that described above for art~culated arrls 11 and 12 in the f~rst embod-iment. The spaclng between the coupling braclcets 37 through 42 permits the bags to be mounted without any obstacle. Re:inforcing braclcets 45 and 46 are p~votally mounted on the left upper articulated arm 33 and right upper articulated arm 34 respeclLvely. These reinforc1ng braclets have a hool-shaped lower free end and they may be pivotally operated to pos~tion in a vertically downward pOSitiOII as shown in F~gure 10 such that they may be respect1vely and select~vely securing the rear section of the upper and lower art~culated arms 31 and 32 together to prov~de extra reinforcement of, part~cularly, the rear sections of the lower articulated arm 32 during its openin~ and closlng operations. lhe reinforcing braclcets 45 and L~ may he pivoted away lo disengage from the lower articulated arm 32 during the mounting of the bags 43 thereto.
It can he apprecLated by lhose s'~illed in the art that the system as shown ~n the second emhodiment may have a reversed construct~on in wlich the lower art~culated arm may he secured to the vert1cal wall and t,he upper articulated arm is provided with free ends for mount~ng the bags. In such reversed constructions the coupling braclcets would have a C-shape coupled at its lower end to the lower articulated arm, allowing free space around the upper articulated arm.
~ o~s~
Furthermore, instead of the sectional articulaed construction, the articulated arm may be in the form of elongated arms made of a flexible material and having a cross sectional con:figuratloll there-Ln such that the arms will bow sideways outwardly away from each other in their middle portlon wllen an axial force LS al)plied to their cantilever;ed free end or when theîr middle portions are pulled away from each other. Thus, the bowed out mLddle portions of the two arms form an expanded loop s-imilar to the sectional articulated arms. The flexible arr,ls will resume their parallel condit~on wheil the ax~al force is rernoved. The bowed out rlliddle port~ons of the two arms may maintain the expanded loop aft,er the axLal force ~s removed by us~llo a rnovable stopper d~aoonally across the loop from one arm to the other.
Also, the ilexible bap,s for the present system may bave handle holes or harldle extension loops below the top edge piplngs or tubings. This w-Lll facilitate carrying the bag after being removed from the arms, and also allows the bag to be re-used as a normal carrier bag.
Obvlously, numerous modif~catlons and variations of the present invent~on are possible in l~ght of the above teachings. It is therefore to be understood that withln the scope of the appended clair,ls, the -invent~on may be pract-iced otherwise than as spec1fically descr~bed herein.

The principal requirement of the mounting and dispensing system is to have arms that are substantially parallel to each other in the closed position to facilitate the mounting and removal of a flexible bag on and along the arms, as well as operative sideways outwardly away from each other in their middle portion to maintain a flexible bag in the opened position for filling operation.
In an exemplary embodiment, the flexible bags mounting and dispensing system primarily comprises a right articulated arm member and a left articulated arm member mutually parallel to each other and are equal in length. Each of the articulated arm member has three section members, namely a front section member, a middle section member and a rear section member. The front section member has a rear end hingedly coupled to the front end of the middle section member. The other end of the middle section member is hingedly coupled to the front end of the rear section member. The rear end portion of the rear section member has a free end portion operative for mounting - ,~ o~s~
the system in a cantilever manner on a vertical mounting wall.
The flexible bags have mounting pipings or loops provided on their opening edge portion such that the bags can be threadingly mounted on the rear section member of the articulated arms. A bag can be pulled over the front section member and the middle section member for use.
The system is set up in such a way that when the arms are pushed towards each other, the system becomes in a closed state, where the arms form two parallel lines juxtaposed to each other. However, when the arms are pulled away from each other, they are no longer in parallel, and the system becomes an open state. The basic idea is that when the arms are in parallel, i.e., the system is in a closed state, a bag mounted on the arms through pipings provided on its opening edge portion can be pulled along the arms all the way until the end of the arms, thus providing an empty bag in a closed state mounted on the arms.

l~ith reference to the drawings wherein like reference numerals indicate same parts in the several different views, the system of the present învention is shown in an exemplary embodiment which includes an articulated bracket 10 having two equal length articulated arms 11 and 12. The articulated arms 11 and 12 are normally positioned mutually parallel to each other and each comprises of three section members, namely, front section members 13, 14, middle section members 15, 16, and rear section members 17, 18 respectively. The front end of the front section members 13 and 14 are pivotally coupled together and preferably hingedly coupled to a short cross member 19 as best shown in Figures 2, 3 and 4. The rear end of the front section members 13 and 14 are respectively hingedly coupled to one end of the middle section rnembers 15 and 16 respectively to form pivotal operating joints 20 and 21. These joints preferably have a configuration similar to a tongue and groove joint in which a slot is formed at the end of one ~53gX) section while a tongue-like end extension section is formed in the other section. The extension section is pivotally fitted into the slot of the associated section and the two sect-ions are pivotally secured together by a pin 22. The other end of the middle section member 15 and 16 are respectively hingedly coupled to the front end of the rear section member 17 and 1~
with similar tongue and groove joints. The rear portion of the rear section memher 17 and 1~ are connected to a free end mounting section 23 which may be L-shaped as shown and operative for mounting the articulated bracket ln in a cantilever manner by being inserted removably into a sheath bracket provided on a mounting means such as a wall or a post.
The flexible bags for the present system have a reinfor-ced double layer edge portion around its opening forming tubings or pipings 24 and 25 along each half portion therein.
The bags may be joined together at their upper end portion such that the pipings 24 and 25 are continuous from bag to bag, so that the bags may be easily and simply mounted on the artlculated arms 11 and 12 by inserting the latter through the pipîngs 24 and 25 respectively and pulling the bags tight together to hang onto the rear section mernber therein. The side of each bag may also be connected to the si-de of the bas next to it by perforated lines. The perforated lines will make it easier to separate the bags from one another. The bags may be easily and simply mounted onto the articulated arms 11 and 12 by first disconnecting the bracket 10 from the mounting section 23, and then inserting the end of the rear section members 17 and 1,~ through the pipings 24 and 25 respectively and pulling the bags tishtly together to hang onto the rear section mernbers therein. The bracket 10 is then connected back ~tO53~
to the mountîng section 23 for mounting to the wall bracket.
When a bag needs to be used, the first bag from the front end of the rear section members is pulled along the artïculated arms to extend over the front and mîddle section members.
The articulated arms 11 and 12 normally maintain the opening of the bag for use in a closed condition. When it is required to fill the bag, the bag may be opened by pulling the operatlng joints 20 and 21 outwards away from each other so that the articulated arms 11 and 12 are extended in a diamond-shaped configuration as shown in Figure 3 to maintaîn the bag ln an opened condition. The bag may he closed again by simply returning the operating joints 20 and 21 towards each other until the articulated arms 11 and 12 are în the substantially parallel posLtîon again. Thus, the bag mounted on the articulated arms 11 and 12 may be used for temporary storage purposes until the bag is full then, if desired, it can he removed from the bracket. To remove a bag from the bracket, the bag is pulled towards the cross member 19 along the articulated arms all the way until the pipings on its top edge are squeezed around the front end arms of the front section members.
A tie 2~ may be provided on the bag such that it is operati~Te conveniently for tying the bag after ît top edges have been squeezed to close together.
Two spring-mounted severing cutters 27 and 28 are - provided at the front end of the front sectîons 13 and 14 as best shown in Figure 4. The cutters 27 and 28 may be operated ~ to sever the pipings or tubings 24 and 25 of the bag such that r the latter may be removed from the articulated arms 11 and 12 after it has been fllled and tied by the tie 26. The filled ~53~
1~
bag may then be removed by pullîng away along the perforated line from the next spared bag. Since the pipings 24 and 25 are continuous from bag to bag, whenever a bag is pulled towards the front of the bracket to he removed, a new bag is automatically pulled forward to replace it and it is already raounted on the bracket 1n a closed cond-Lt-on and is ready to be used as soon as the bracket is opened, as described above.
This operation may be repeated unt-Ll all the baos nounted on the rear section members are expended, at which point another group of bags may he mounted onto the rear section members as described above.
Alternat~vely, instead of rnounting the bags onto arms 17 and 18, the bags raay be supplled from a cont~nuous roll, also having mounting pipings or tubings provided in their openings with the bags serîally connected by an impression line one after another. The bags will be mounted onto the bracket 10 through the front end of the front sect-ion members 13 and 14.
Tlowever, ln this case, the cross meraber 19 will not be used.
In th1s conflguration, the rear portion of the rear section mernbers 17 and 18 may be extended and bent to form an L shape and to act as a stand by -itself. The bags -in thLs case may be pulled, after being filled, all the way along section members 17 and 1~ hor~zontally and then through the L-shaped portion.
Cutters may eîther be located at the horizontal part of the rear section rnembers 17 and 18, or at the vertical or slanted part of the rear section memhers 17 and 1~. Also, the rear sect-~on members 17 and 1~ may be made shorter or eliminated for certain applications, and the rear portion of the middle section members 15 and 16 may be used for mounting.
Alternatively, the bags may have perforated lines at the c~Q535aC) Il top edge therein so that in order to remove each bag from the arms, the bag may be pulled down and it will breal~ away from the mounting bracket alono the perlorated line. To further facilitate the removal of the bags from the arrns, instead of pipinos or tubings 24 and 25, the bags may be provided w-ith a plurality of mounting loops 29 as shown in F1gure 7 and the bags may be mounted onto the art1culated arms 11 and 12 with the loops 29. The loops may also be perforated at the top edge therein.
In a second embodiment as shown in Figures ~ and 9, the mounting braclcet 30 comprîses of two sets of parallel articulated arms namely an upper articulated arms 31 and a lower artLculated arm 3?. ~ach art-iculated arm has a construct1on similar to the articulated arms 11 and 12 as described above. The upper articulated ar-n 31 has a left art1culated arm 33 and a rigl-lt articu1ated arm 34. The lower articulated arm has a left articulated arm 35 and a right art1culated arm 3~. Three -inverted IJ-shaped coupling brackets 37, 3~, and 39 a~e provided at the front, middle and rear sections respectively of the upper left articulated arm 33, and three s1MLlar lnverted U-shaped coup1Lng brackets 40, 41 and 42 are provided at the front, mlddle anc~ rear sectlons respect1vely of ~he upper right artlculated arrn 34. Fach coupl1ng bracket has an inner leg IL and an outer leg OI.
extending respectively downwards from the upper articulated braclet 31 to locate 1n a spaced manner on the lnside and outside of the lower articulated arm 32. The coupling brac!~ets 37 through L2 wlll cause the upper and lower artLculated arms 31 and 32 to operate ~Ln unl<,on with each ot'ner, namely, when the upper articulated braclet 31 is -in the closed or opened ~?e~3~c~
IZ
condîtion selectively, the lower artîculated arm 32 will also correspondingly be in the closed or opened condition simultaneously as selected.
The free end of the lower articulated arm 35 and 36 may curve slightly downwards and be slightly pointed such that a bag 43 may be pulled from a roll 4L~ to mount onto the lower art~culated arms 35 and 36 simîlar to that described above for art~culated arrls 11 and 12 in the f~rst embod-iment. The spaclng between the coupling braclcets 37 through 42 permits the bags to be mounted without any obstacle. Re:inforcing braclcets 45 and 46 are p~votally mounted on the left upper articulated arm 33 and right upper articulated arm 34 respeclLvely. These reinforc1ng braclets have a hool-shaped lower free end and they may be pivotally operated to pos~tion in a vertically downward pOSitiOII as shown in F~gure 10 such that they may be respect1vely and select~vely securing the rear section of the upper and lower art~culated arms 31 and 32 together to prov~de extra reinforcement of, part~cularly, the rear sections of the lower articulated arm 32 during its openin~ and closlng operations. lhe reinforcing braclcets 45 and L~ may he pivoted away lo disengage from the lower articulated arm 32 during the mounting of the bags 43 thereto.
It can he apprecLated by lhose s'~illed in the art that the system as shown ~n the second emhodiment may have a reversed construct~on in wlich the lower art~culated arm may he secured to the vert1cal wall and t,he upper articulated arm is provided with free ends for mount~ng the bags. In such reversed constructions the coupling braclcets would have a C-shape coupled at its lower end to the lower articulated arm, allowing free space around the upper articulated arm.
~ o~s~
Furthermore, instead of the sectional articulaed construction, the articulated arm may be in the form of elongated arms made of a flexible material and having a cross sectional con:figuratloll there-Ln such that the arms will bow sideways outwardly away from each other in their middle portlon wllen an axial force LS al)plied to their cantilever;ed free end or when theîr middle portions are pulled away from each other. Thus, the bowed out mLddle portions of the two arms form an expanded loop s-imilar to the sectional articulated arms. The flexible arr,ls will resume their parallel condit~on wheil the ax~al force is rernoved. The bowed out rlliddle port~ons of the two arms may maintain the expanded loop aft,er the axLal force ~s removed by us~llo a rnovable stopper d~aoonally across the loop from one arm to the other.
Also, the ilexible bap,s for the present system may bave handle holes or harldle extension loops below the top edge piplngs or tubings. This w-Lll facilitate carrying the bag after being removed from the arms, and also allows the bag to be re-used as a normal carrier bag.
Obvlously, numerous modif~catlons and variations of the present invent~on are possible in l~ght of the above teachings. It is therefore to be understood that withln the scope of the appended clair,ls, the -invent~on may be pract-iced otherwise than as spec1fically descr~bed herein.
