Abstract
Description
- The present invention relates to a section bar for shower box, sauna box and the like, a door frame comprising said section bar and a method of manufacturing said section bar.
- It is known that there are several different configurations of shower and sauna boxes that are suitable for corner or wall installations, and generally consist of one or more panels combined together according to different closing systems.
- One of the main requirements of the panels constituting a shower box or the panels to be used on top of a bathtub is perfect mating between them so that the shower area is well sealed in order to avoid water dispersion during use. In the particular case of sauna boxes, this requirement is directed to avoid steam dispersion.
- Presently, in the large-scale retail trade there are shower boxes that can be directly assembled in situ not necessarily by qualified staff; this involves design choices capable of facilitating mounting of same.
- The walls, that can consist of sheets of plastic material or glass can be in the form of swing panels, sliding or folding panels, etc. and are assembled by suitable structures of metal or plastic material.
- If required, they are further provided with seals or flexible lips for hermetic tightness in the horizontal lower contact regions, along the contact region with the ceramic surface of the shower pan for example, or in the vertical side contact regions, such as along the articulation axis of the panel or yet along the closing axis between two walls. The latter can often be provided with magnetic seals ensuring closure.
- Said technical expedients ensure more tightness and more insulation to the shower boxes, sauna boxes and the like, as compared with use of mere curtains, but in some cases, above all at the junction points of the section bars along the lower perimeters as regards the shower boxes, and generally along the whole perimeter of the structure in the case of sauna boxes, these expedients are not sufficient to avoid escaping of water or steam from the panels.
- Presently, for junction of the section bars, coupling surfaces having minimum tolerances between the two pieces to be connected can be obtained by mechanical working, followed by possible application of glues or sealing agents, or premoulded plastic joints are used that are suitably shaped for assembly of the two vertical and horizontal section bars. In the last-mentioned case too, application of glues or sealing agents is required.
- While the known art briefly described above is presently widely used on the market and accomplishes the intended tasks in an optimal manner, it however appears to be susceptible of improvements under different points of view.
- In fact, the above described techniques have limits residing in the reduced duration of tightness due to the mechanical stresses to which the joints are submitted during the opening and closing steps, and by effect of rubbing in the work plane tending to disconnect the glued parts. In addition, the manual operations for sealing are expensive and do not ensure a constant result. Finally there are also problems of aesthetic nature.
- Accordingly, the present invention aims at substantially solving all the drawbacks highlighted above.
- A first aim of the invention is to ensure hermetic tightness in time without application of glues or sealing agents.
- Another aim is to guarantee a constant quality of the pieces to be assembled without further interventions for new gluing or replacement of the angle elements for junction and sealing.
- A general aims of the invention is also manufacture of a section bar for panels and of a door frame that can be easily mounted and give better aesthetic results.
- In addition, the present invention aims at carrying out a method for obtaining section bars for shower box, sauna box and the like, and a method for assembling door frames comprising these section bars.
- The foregoing and further aims that will become more apparent in the progress of the present description are substantially achieved by a section bar for panels according to the appended
claims 1 to 11, by a frame door for shower box, sauna box and the like according toclaims 13 to 15, and by a method of manufacturing section bars according toclaim 12, as well as a method of manufacturing door frames according toclaims 16 to 18. - Further features and advantages will be best understood from the detailed description of a preferred but not exclusive embodiment of the invention, in which:
-
Fig. 1 is a perspective view of a portion of a section bar for shower box, sauna box and the like in accordance with the present invention; -
Fig. 2 is an elevation side view of the section bar inFig. 1 ; -
Fig. 3 is an elevation front view of the section bar shown inFig. 1 , seen in section; -
Fig. 4 is a section view of a known section bar for shower box, sauna box and the like, to be coupled with the section bar in accordance with the present invention; -
Fig. 5 is a perspective view of a door frame portion in accordance with the present invention; -
Fig. 6 is a perspective view of a portion of a section bar for shower box, sauna box and the like in a second embodiment; -
Fig. 7 is a perspective view of a section bar portion in accordance with the present invention, in a third embodiment. - With reference to
Fig. 1 , a section bar for shower box, sauna box and the like in accordance with the present invention has been generally identified byreference numeral 1. -
Section bar 1 comprises at least onemain body 2 of longitudinal major extension, defining aseat 3 having a U-shaped profile and designed to hold an edge of apanel 4 constituting a door frame for shower box, sauna box and the like. - Seat 3 is delimited by two
side walls 5 and abase 6 and has an aperture 7 opposite tobase 6. Located on theside walls 5, close to aperture 7 and mutually facing, are twoteeth 23 reducing the entry section ofseat 3 so as to increase the interference betweenbar 1 andpanel 4 and thus ensure better coupling. - As shown in
Figs. 2 and3 , afirst lip seal 8 extends underbase 6 ofseat 3, away from themain body 2, in the opposite direction to that towards which aperture 7 of theU-shaped seat 3 is turned. - In particular, the
first lip seal 8 has an elongated form and extends substantially straight between afirst end 24 connected tobase 6 ofseat 3, and a secondfree end 25. - Along the extension of the
first lip seal 8 there is a localised cross-section narrowing, disposed close to thefirst end 24 and giving more flexibility to thefirst lip seal 8. - This
first lip seal 8 has alower edge 8a substantially parallel to thelongitudinal axis 3a of theU-shaped seat 3. - At least at a
first end 2a of themain body 2 there is a connectingelement 9 shown inFigs. 1 and2 , which is overmoulded, along an overmoulding region S, both onseat 3 and on thefirst lip seal 8, so as to form a single body therewith. The overmoulded region S is highlighted in the accompanying drawings for explanation purposes alone; in the final product this region is not visible so that the section bar shows an aesthetic continuity, without interruptions in the material. - In particular, the connecting
element 9 comprises anupper portion 10 overmoulded on themain body 2 and alower portion 11 extending away from theupper portion 10, overmoulded on thefirst lip seal 8 in such a manner as to form a single sealing edge therewith. - In the preferred embodiment shown in the accompanying drawings, the
upper portion 10 of the connectingelement 9 has a U-shaped conformation and constitutes an extension of theU-shaped seat 3 of themain body 2. Thus, a single holding region is formed for an edge ofpanel 4 made of glass or of plastic material. - The
lower portion 11 of the connectingelement 9 comprises aninterference tab 12 made of one piece construction with theupper portion 10 and defining an extension of thefirst lip seal 8. - This
tab 12 is delimited by alower edge 13 in alignment with thelower edge 8a of thefirst lip seal 8, and of which it constitutes an extension. In addition,tab 12 is delimited by aside edge 14 of such an inclination that angle "a" included between thisside edge 14 and thelower edge 13 oftab 12 is an acute angle. - Advantageously,
section bar 1 further comprises asecond lip seal 15 projecting away from one of the twoside walls 4 of themain body 2. Thissecond lip seal 15 is inclined to thefirst lip seal 8, so as to identify an acute angle "b" therewith. - In the configuration of a door frame with swing panels, the
interference tab 12 of asection bar 1 mounted on a first panel faces theinterference tab 12 of asection bar 1 mounted on a second panel, in such a manner that, in the closed configuration of the door frame, the two tabs interfere with each other by overlapping and ensure tightness of the shower box or sauna box. In the same manner if the door frame is of the sliding panel type,tab 12 partly overlaps the vertical jamb of the structure delimiting the shower box or sauna box, thus efficiently closing the lower junction region. - The connecting
element 9 further comprises awing 16 laterally extending away from theupper portion 10. Thiswing 16 is overmoulded on thesecond lip seal 15 and defines an extension of same. In this manner,wing 16 and thesecond lip seal 15 constitute a single deviating edge preventing water or condensate drops from escaping therefrom because they are deviated towards the inside of the shower box or sauna box, in particular towards the inner region of the shower pan or sauna area. - Preferably, as shown in
Fig. 3 , the deviating edge has a curved outline in section along a plane orthogonal toaxis 3a ofseat 3, the convexity of which faces the sealing edge; this course facilitates the descent of water or condensate drops. Alternatively, this deviating edge can be straight, but always transverse to thefirst lip seal 8. - The connecting
element 9 further comprises latching means 17 to couple thesection bar 1 to a generic section member preferably disposed at a position perpendicular to thesection bar 1. - In a preferred configuration shown in
Fig. 2 , this latching means 17 projects from theupper portion 10 in the opposite direction to the extension direction of thelower portion 11. This latching means 17 advantageously consists of bayonet joints or elements that are joined by interlocking or interference fit to respective elements made on the generic section member to whichsection bar 1 is to be connected. - The
main body 2 ofsection bar 1 is generally made of rigid, opaque or transparent, plastic material such as rigid PVC (polyvinylchloride), polycarbonate, polystyrene and polypropylene, possibly with a metal core. - This is made necessary because
panel 4 is to be inserted inseat 3 of themain body 2 by exerting pressure so as to spread the twoside walls 5 apart, saidpanel 4 being then steadily retained in place by effect of the return spring force of the material and possibly also ofteeth 23. - The first 8 and second 15 lip seals are on the contrary made of flexible material such as elasticised PVC, thermoplastic styrene, polyurethane or polyolefin rubber.
- The connecting
element 9 too is preferably made of a flexible rubber material, preferably of the same nature as that used for the first andsecond lip seals - In particular, the sealing edge, defined by the
first lip seal 8 and by thelower portion 11 of the connectingelement 9, must be flexible because in the closed position of the door frame it abuts against the outside structure of the shower box or sauna box, and it slightly deforms so as to adhere to this structure and avoid water or steam escape. - Generally,
section bar 1 is made by co-extrusion, in a single block, of themain body 2 and the first 8 and second 15 lip seals. - Advantageously, the U-shaped seat is co-extruded using transparent rigid plastic material and bright metal; in fact, metal improves the aesthetic result of the section bar, in addition to possibly increasing the structural resistance of the
main body 2. As an alternative to insertion of the metal strip, a similar effect can be obtained by application of a metallized polyester tape. - Once the individual block consisting of the
main body 2 and of the first 8 and second 15 lip seals has been extruded, the connectingelement 9 is overmoulded on this block, at least at thefirst end 2a of themain body 2. In particular, theupper portion 10 is overmoulded on themain body 2, thelower portion 11 is overmoulded on thefirst lip seal 8 andwing 16 is overmoulded on thesecond lip seal 15. - In an alternative configuration not shown, preferred in the presence of particular aesthetic effects such as the metallized effect, the
main body 2 is provided to extend alongaxis 3a beyond the end of thefirst lip seal 8, so that the holding region designed to couple with an edge ofpanel 4 made of glass or plastic material exclusively consists of theU-shaped seat 3, and not of the U-shaped seat and theupper portion 10 of the connectingelement 9, as in the preferred configuration.
This allows a holding region of the panel with a metallized effect to be obtained even at the corner portion, so as to achieve a better final aesthetic result. - The
upper portion 10 of the connectingelement 9 in this case is not U-shaped but comprises part of theinterference tab 12. Therefore a connectingelement 9 consisting of theinterference tab 9 alone as shown inFig. 6 , is obtained. - The
section bar 1 in accordance with the present invention preferably applies to a lower horizontal edge of apanel 4 made of glass or plastic material defining adoor frame 18 for shower box, sauna box and the like. Generally, thispanel 4 is laterally bordered with at least onesection member 19 of known type, comprising amain portion 20 of longitudinal major extension defining aU-shaped seat 21 to be coupled topanel 4. Externally of theU-shaped seat 21, along the whole longitudinal extension of themain portion 20 there is aseal 22. Should thissection member 19 be applied to a side vertical edge ofpanel 4 placed at the opening or closure of the shower box or sauna box,seal 22 is preferably of the magnetic type. -
Section bar 1 in accordance with the present invention can be coupled in a removable manner with theside section member 19 applied topanel 4, through said latching means 17. Alternatively, the connectingelement 9 can also be overmoulded on oneend 19a of theside section member 19, thus defining a single L-shaped section bar or angle as shown inFig. 7 . - In the same manner, a second connecting
element 9 can be applied through overmoulding also to asecond end 2b of themain body 2. In this manner, ifpanel 4 has asecond section member 19 applied to the second vertical side edge ofpanel 18, this second connectingelement 9 can be connected to thesecond section member 19 either in a removable manner through the latching means 17, or in an irremovable manner through overmoulding. In the last mentioned case a U-shaped section bar is obtained. - In particular, in the case of sauna boxes it is necessary for the
door frame 18 to be provided with asection bar 1 in accordance with the present invention also on the upper edge ofpanel 4, to avoid escape from the box of the steam produced therein. Alternatively, the upper edge ofpanel 4 can be coupled to a generic section member of the previously described type. - The invention achieves the intended purposes; in fact the section bar being the object of the present invention simplifies the operations for assembling shower boxes or sauna boxes, because the angular connecting elements are already included in the section bar itself. Actually, overmoulding of the connecting element on the main body and on the first lip seal simplifies the working and mounting operations since no mechanical working is required in order to obtain junction surfaces with minimum tolerances, and gluing of the angular elements or angle bars to the rest of the section bar is avoided. Such a section bar in accordance with the present invention ensures hermetic tightness of the door frame in time without using glues or sealing agents.
- Finally, the absence of adhesives or cements allows the aesthetic result of the whole door frame to be improved because there are no possible glue smears during assembling.
