Abstract
A B S T R A C T
Open joining ring, in particular for connecting the peripheral flanges of the two elements forming the washing tank of a washing machine An open joining ring, in particular for connect-ing the peripheral flanges of the two elements forming the washing tank of a washing machine, consists of a channel-shaped element (6) which is curved so as to form a ring and made of metallic material and which has two lateral wings (7) and a central bottom wall (8) which define a substantially C-shaped cross-section, with the cavity facing the axis of the ring. The channel-shaped element has, at each of its adjacent ends, a portion (9) staggered radially outwards, which also has its cavity facing the axis of the ring, said staggered portion being formed as a single piece with the abovementioned channel-shaped element. The part of the bottom wall (8a) of the channel-shaped element which connects the bottom wall (9a) of each end portion to that of the immediately adjacent part of the channel-shaped element has a hole (10) which defines, together with the cavity of the end portion (9), a passage for engagement of a clamping bolt.

Description
12894~
Open joining ring, in particular for connecting the peripheral flanges of the two elements forming the washing tank of a washing machine The present invention relates to open joining rings, in particular for connecting the peripheral flanges of the two elements forming the washing tank of a washing machine, of the type consisting of a s channel-shaped element, which is curved so as to form a ring and made of metallic material and whic~ has two lateral wings and a central bottom wall which define a substantially C-shaped cross section, with the cavity facing the axis of the ring; the said channel-shaped element having at its two adJacent ends respectlve passages for engagement of a tangential clamping bolt.
Rings of the aboyementioned type have been known and used for some time, the adjacent ends of ~'~ these rings being bent outwards, substantially at right angles in rel~ation to the adJacent part of the ring, - and having a pair.of facing~holes for engagement of the clamping bolt,.l~he rings,.,of.,this type.are~not~completèly satisfactory during use, owing to the tendency, of the ~"~ two deformed ends of :the ring to be further deformed 20'~as a ~esult~..of the pulling,of the bolt, at the same time preventlng ~corre,ct,,,clamping of.,the , connected , parts.'Rings are aLso,known,~ the adjacent ends of whlch :are~ provided with welded:-:auxiliary elements.,:.having s~:,aligned passages: for,'.engagement,.of, the. clamping bolt.

2~ The:~'rlngs:of the~latter type enable.the connectéd parts to be effectively clamped in the, requ,ired manner, but ,. ~ ~ ~ , , , . ; " , ~ ~ , ., : , . -: ~ : -: , ~894~9 are complicated and costly to manufacture.
The object of the invention is to provide a ring of the type mentioned at the beginning of the present description, which is both functional and simple and economic to ma~ufacture.
The main characteristic feature of the ring according to the invention consists in the fact that the abovementioned channel-shaped element has, at each of its ends, a portion staggered radially outwards, which also has the cavity facing the axis of the ring, said staggered portion being formed as a single piece with the ring, and in that the part of the bottom wall of the channel-shaped element which connects the bottom wall of each end portlon to that of the immediately ad~acent part of the channel-shaped element has a hole which deflnes, together with the cavity of the said end portion, a passage for engagement of the clamping ; bolt.
In a preferred embodlment, the two above-mentioned end port~ions are able to fit one inside theother when the bolt is clamped, so as to improve further the clamping efficiency.~ ~
The end portions staggered radially outwards are obtained by means of ~cold deformation of the 2~5~ profLled element, preferably~performed at the same time as~punching of the abovementioned hole in the ehd wall of the profiled~element.
Farther characteristlc features and advantages of the invention will emeige from the description which follows with reference to the attached drawings, ... ,, ~ :

provided purely by way of a non-limiting example, in which:
Figure 1 is a partial sectional view of a ring according to the invention during use;
Figure 2 is a front view of the two end portions of the ring shown in Figure 1, when not in use;
Figure 3 shows the two end portions when clamped;
Figures 4 and 5 show the end of the profiled element forming the ring according to the invention, respectively before and after the operation required to produce the part for engaging the clamping bolt;
Figure 6 is an exploded perspective view of Figure 3, and , 15 Figure 7 shows ~a preferred variant of the ring shown in Figure 3.
Figure 1 shows a detail of a washing tank 1 of a washing ~machine, the--body~'of~-whlch-consists of a ' substantially :cup-shaped element 2 and:of a disc 3 which closes, the mouth of the,cup-shaped element 2 at the front~ and which~ has~an opening in the centre (not vlsibl~e ln the F-igure)~ for introducing the laundry. At their- jolnlng edges,~ the ~.elemènts 2, 3 have two clrcumferential~ flanges,.,2a,,~3a:;~between ~which a seal 25~ 4~ is placed.~ The two flanges Za, 3a are connected to each~other by an open-~oining~ring 5.of the type'forming ': t;he:~ subject of thé~' present'.,invention (obviously the ;rlng"~accordlng to,tho,~lnvention can' also be used:with~ ~ -tank ;structures ~of ~a typé~dlfferent from that shown,-30;~:1n whlch~the~Joining~:,flanges are provlded'ln a plane 1289~3~
equidistant from the two end faces of the tank or onthe rear face rather than the front face as in the example shown). The ring 5 consists of a channel-shaped element 6 made of metallic material and having two lateral wings 7 and a central bottom wall 8 which define a substantially C-shaped cross-section, with the cavity facing the axis of the ring. The channel-shaped element 6 has, at each of its two adjacent ends, a part 9 staggered radially outwards, itself also having the cavity facing the axis of the ring. The end part 9 is obtained by means of cold plastic deformation of the channel-shaped element. Figures 3 and 4 show the end portion before and after plastic deformation, respect ively. The section 8a of the bottom wall 8, which connects the bottom wall 9a of the end portion 9 to the bottom wall of the immediately ad~acent section of the channel-shaped element, has a hole 10 obtained by means of punching. The hole 10 and the cavity of the respect-ive end portion 9 form a passage through which a screw 11 can be inserted. The screw 11 is intended to pass through both the end--portions 9 so as to permit, together with a clamping nut 12, clamping of the ring 5 onto the flanges 2a, 3a. The bolt consisting of the screw 11 and the nut 12 therefore forms a bolt-for tangentially clamping the ring 5, enablLng the two end portions 9 to be~ moved~ towards each other from the - inoperative position shown in Figure 2.
Figure~7 shows a different embodiment in which the end portions 9 of the channel-shaped element 6 are ,:

``` 1289439 is clamped, so as to make the connection more secure.
Preferably, the operation required to deform the channel-shaped element 6 so as to define the end portion 9 staggered radially outwards and the operation required to make the hole 10 in each end portion g are performed simultaneously.
Obviously, the principIe of the invention remaining the same, the constructional details and the embodiments may vary widely with respect to that which has been described and illustrated purely by way of example.
