KR 2000 0033178 A - The Applicant observed that known fasteners suffer from some drawbacks related to their assembly and disassembly.
- In fact, the Applicant verified that the known means for fixing the fasteners (like the lugs and bosses of
EP1793029 ) does not grant a safe attachment and are not easy to handle during mounting and dismantling of the sleeve. - It is therefore a main object of the present invention to overcome the above-mentioned drawbacks by providing a fastener in the form of a clamping framework surrounding at least one end of the sleeve which is easy to assemble and disassemble.
- Another object of the present invention is to provide a clamping framework which allows the sleeve to be mounted and dismantled quickly and easily.
- Another object of the present invention is to provide a clamping framework which allows the sleeve to be mounted safely into the washing and/or drying machine and assure the correct and steady position of said sleeve during operation of the machine.

- A washing and/or drying machine, comprising:a housing (C) having an access opening (5);a rotating drum (2);a tub (T) having a tub opening (8) and enclosing the rotating drum (2);a sleeve (11) disposed between the access opening (5) of the housing (C) and the tub opening (8) of the tub (T);at least one clamping framework (12) surrounding at least one end of the sleeve (11) to fasten said sleeve (11) to the housing (C) and/or to the tub (T);said at least one clamping framework (12) comprising a first U-shaped frame (13) and a second U-shaped frame (14) and a first connecting device (16) and a second connecting device (16), each of the first and second connecting device (16) being configured to releasably connect the first frame (13) to the second frame (14),each of the first and the second connecting device (16) comprising a first part (15) provided with a first toothed profile (21) engaging a second part (17) provided with a second toothed profile (29), wherein one end of the first U shaped frame (13) comprises the first part (15) of the first connecting device (16), the other end of the first U shaped frame (13) comprises the second part (17) of the second connecting device (16);wherein one end of the second U shaped frame (14) comprises a first part (15) of the second connecting device (16), the other end of the second U shaped frame (14) comprises the second part (17) of the first connecting device (16);wherein each first part (15) comprises an elongated element (18) provided with the first toothed profile (21) and delimiting, together with the respective end (19) of the first frame (13) or of the second frame (4), a slot (20);wherein each second part (17) presents a seat (26) placed at the respective end (25) of the second frame (14) or of the first frame (13) and configured to accommodate the elongated element (18);wherein the teeth of said first and second toothed profiles (21, 29) project substantially perpendicular to a surface (S) on which the clamping framework (12) lies.
- The machine of claim 1, wherein the first toothed profile (21) lies on a face of the elongated element (18) substantially parallel to the surface (S) on which the clamping framework (12) lies.
- The machine of claim 1 or 2, wherein the second toothed profile (29) is placed inside said seat (26) and lies substantially parallel to the surface (S) on which the clamping framework (12) lies.
- The machine of claim 3, wherein the seat (26) presents a front opening (27) to allow insertion of the elongated element (18) into said seat (26) and engagement of the first toothed profile (21) with the second toothed profile (29).
- The machine of any of the previous claims, wherein the second part (17) comprises a C-shaped body provided with a first tab (22), a second tab (23) and a connecting portion (24) delimiting said seat (26).
- The machine of claim 5, wherein said seat (26) opens laterally towards the outside of the clamping framework (12).
- The machine of claim 5 or 6, wherein the connecting portion (24) is configured to be inserted into the slot (20) to engage the first and second toothed profiles (21, 29).
- The machine of claim 5, 6 or 7, wherein, when the connecting device (16) is assembled, the first tab (22) presents an inner surface comprising the second toothed profile (29) facing the first toothed profile (21) of the elongated element (18); wherein the second tab (23) presents an inner substantially smooth surface (30) configured to come into contact with a surface of the elongated element (18) opposite the first toothed profile (21).
- The machine of any of claims 5 to 8, wherein the first tab (22) and/or the second tab (23) are flexible so to allow disengagement of the first toothed profile (21) from the second toothed profile (29) by exerting a force on the first part (15) and/or the second part (17) along a direction substantially perpendicular to the surface (S) on which the clamping framework (12) lies.
- The machine of claim 8, wherein the second toothed profile (29) is shorter than the inner surface to allow an easy disengagement of the toothed profiles (21, 29).
- The machine of any of claims 5 to 10, wherein the second part (17) comprises a protrusion (31) placed on the opposite side of the C-shaped body with respect to the front opening (27), wherein a rear portion (32) of the elongated element (18) and said protrusion (31) are configured to be clamped by an assembly tool to insert the elongated element (18) in the seat (26) through the front opening (27) when mounting the clamping framework (12).
- The machine of any of the preceding claims, wherein the teeth of the first toothed profile (21) are placed one after the other along a first direction (Y); wherein the teeth of the second toothed profile (29) are placed one after the other along a second direction (Z); wherein engagement of the first toothed profile (21) with the second toothed profile (29) is performed by aligning the first and second directions (Y, Z) and making the first toothed profile (21) and the second toothed profile (29) slide one over the other along said first and second common directions (Y, Z).
- The machine of any of the preceding claims, wherein the first U-shaped frame (13) and the second U-shaped frame (14) are identical and each comprises one first part (15) placed on a first end and one second part (17) placed on a second end.
