Description

[0001] FIXING BODY FOR WALL-HUNG SANITARY WARE AND KIT INCLUDING SAID FIXING BODY

[0002] * * *

[0003] TECHNICAL FIELD

[0004] The present invention relates to a fixing body and a kit for the suspended fixing of a sanitary fixture comprising such fixing body.

[0005] Although in the following reference will mainly be made to a sanitary fixture in the form of a toilet, this does not exclude that the object of the invention is also applicable to other types of sanitary fixtures.

[0006] TECHNIQUE NOTE

[0007] The suspended fixing of a sanitary fixture, such as a toilet, is carried out by installing two fixing pins on a wall so that they protrude, in particular horizontally, from it.

[0008] In order to be able to be fixed in a suspended position, the sanitary fixture must then have a rear wall that is placed next to and facing the wall, in which two horizontal through holes are made, one for each fixing pin.

[0009] When the sanitary fixture is fitted onto the fixing pins, one free end of the pins is found in an internal cavity of the sanitary fixture, which cavity is open at the bottom, is partially delimited laterally by the vertical rear wall and is delimited at the top by a horizontal upper wall of the sanitary fixture.

[0010] In the said horizontal upper wall, a pair of vertical through holes are generally made, which communicate with the cavity and are usually used to fix the hinges of a toilet seat to the sanitary fixture, in the case of a WC.

[0011] To hold the sanitary fixture in place, which is supported by the fixing pins, a fixing body is used for each fixing pin, which fixing body is inserted into the cavity of the sanitary fixture, through a lower opening of said cavity, before inserting the fixing pins. Each fixing body is equipped with a cavity to accommodate the fixing pin, which in turn is equipped with a tubular or annular internal surface that surrounds a portion of said fixing pin and which is aligned with the respective horizontal through hole, generally by means of a suitable centering body.In the fastening body there is a threaded hole that intersects a portion of the tubular internal surface and into which a threaded body is screwed, along a screwing axis of the threaded hole itself, at least until it protrudes inside the internal cavity, coming into contact with the fastening pin, exerting pressure on it. Essentially, the fastening pin is clamped between the threaded body and a portion of the internal cavity of the fastening body opposite an exit opening of the threaded hole.

[0012] The screw axis lies, as for example in the previous documents EP3O33979, CN219450955U and CN219527850U, on a plane perpendicular to a central axis of the internal surface, or perpendicular to a central or longitudinal axis of the fixing pin, and in use it is substantially coaxial to a respective vertical through hole, so that through said vertical through hole it is possible to insert a tool, such as for example a screwdriver or an Allen key or a socket wrench, and screw the threaded body into the threaded hole.

[0013] A problem with these solutions is that , from one sanitary fixture to another, the distance of the vertical holes passing through the vertical rear wall of the sanitary fixture can vary, consequently a different locking body would be necessary for each sanitary fixture which has a different distance, or the solution proposed by document CN219527850U could be adopted in which the position of the threaded hole, or the horizontal length of the fixing body, can be varied. Similarly, document CN219527850 describes a variable length sleeve.

[0014] However, the variation mechanism of the documents CN219527850U and CN219527850 is expensive, less robust than a single body, and is in any case not usable in the case in which the cavity in the sanitary fixture is horizontally narrow, so that a second vertical rear wall facing the first vertical rear wall (the one directly facing the wall) is substantially vertically aligned below the vertical through hole, which therefore prevents having a fixing body that extends to be vertically aligned with the respective vertical through hole , and prevents a tool from being inserted vertically into the vertical through hole.

[0015] SUMMARY OF THE INVENTIONAn object of the present invention is to overcome the aforementioned constraints of the prior art within the scope of a rational, robust and low-cost solution by means of a fixing kit according to claim 1.

[0016] In particular, the invention provides a kit for installing a sanitary fixture on a wall from which a fixing pin protrudes, comprising:

[0017] - a fixing body comprising:

[0018] - a fixing pin receiving cavity which is provided with, or consists of, a tubular or annular internal surface configured to surround, when in use, at least a portion of said fixing pin,

[0019] - a threaded hole that intersects a portion, for example just a portion, of the tubular internal surface,

[0020] - a threaded body screwable into said threaded hole along a screwing axis of the threaded hole and equipped with a first end, which is external to the internal cavity even when in use and in correspondence with it the threaded body has a tool portion, or grip or connection portion of a tool, configured to allow a removable connection with a screwing tool of the threaded body itself, and a second end, opposite to the first along the screwing axis and insertable inside the internal cavity following the screwing of the threaded body,

[0021] where the screw axis lies on a plane oblique to a central axis of the internal surface.

[0022] Thanks to this solution, even in the case where there is a high vertical misalignment, for example even greater than 10 or 15 mm, between the vertical through hole of the article and the tool portion, or in the case where the vertical through hole has a vertical rear wall of the sanitary fixture underneath it, it is possible to insert the tool through the hole and rotate the tool portion to be able to press the second end of the threaded body against the fixing pin. Furthermore, the system allows, in the case where the sanitary fixture is a WC, to use toilet seats of a single size on WCs that protrude by different lengths with respect to the wall , and which therefore have the fixing holes of the hinges of the toilet seat at different distances from the rear wall. Furthermore, within certain oblique angles,the fixing body can also be used for traditional fixing, in which the tool portion is substantially aligned vertically with the vertical through hole.

[0023] According to another aspect of the invention, said oblique plane may form an angle between 5° and 30° with a plane perpendicular to the central axis, for example between 10° and 20°. In the embodiment said angle is between 13° and 18°.

[0024] By tilting the illustrated embodiment, also considering the clearances between the tool portion and the tool as will be discussed in more detail below, it is possible to implement the kit according to the invention even in case of vertical misalignments of 30 mm - 40 mm.

[0025] According to another aspect of the invention, the internal cavity of the fastening body may comprise an access opening for the fastening pin made at a first end of the fastening body, wherein the threaded hole is made between said first end and an opposite second end, opposite to the first along the central axis of the internal surface of the cavity, and wherein the screwing axis is inclined in the direction away from the first end of the fastening body.

[0026] According to yet another aspect of the invention, the kit may comprise a guide body associable with the first end of the threaded body and configured to guide the screwing tool towards the tool portion of the threaded body.

[0027] This increases the speed of installation, because even if the installation technician does not perfectly direct the tool to rotate the threaded body, the guide body allows the error to be corrected, as the technician simply has to push a tip of the tool against the guide body.

[0028] For example, the guide body can be shaped like a funnel or hopper or cone, or it can be a tubular or annular body whose cross-section (measured along a plane perpendicular to the screwing axis) decreases in the direction of approach to the tool portion.

[0029] According to a further aspect of the invention, the tool portion can be made as at least one of: a recess or a protrusion having a polygonal (regular) crosssection with respect to a section plane perpendicular to the screwing axis, a bladeor cross-shaped notch, a Torx® recess , a recess equipped with a plurality of lobes protruding radially with respect to the screwing axis.

[0030] According to one aspect of the invention, the kit may comprise a centering body associable with the fixing body and configured to center the internal surface of the receiving cavity on the fixing pin.

[0031] The invention also provides a kit containing the fixing pin, in particular the invention also provides a kit for installing a sanitary cabinet on a wall, comprising: - a fixing pin that can be fixed cantilevered to said wall,

[0032] - a fixing body which comprises:

[0033] - a fixing pin receiving cavity which is provided with a tubular or annular internal surface configured to surround, when in use, at least a portion of said fixing pin,

[0034] - a threaded hole that intersects a portion of the tubular internal surface and defines a screw axis,

[0035] - a threaded body screwable into said threaded hole along the screwing axis at least until it protrudes inside the internal cavity,

[0036] where the screw axis lies on a plane oblique to a central axis of the internal surface.

[0037] According to one aspect of the invention, the fixing pin may comprise a recess, facing in use towards the threaded hole, into which a portion of the threaded body can be inserted which protrudes into the internal cavity following screwing of the threaded body into the threaded hole.

[0038] The invention also provides a sanitary apparatus comprising a sanitary fixture and a kit comprising any of the features set forth above, wherein the sanitary fixture comprises:

[0039] -a rear wall that can be placed next to the wall from which the fixing pin protrudes and in which a horizontal through hole is made into which the fixing pin is inserted, - a cavity partially delimited by the rear wall and into which a portion of the fixing pin is inserted which passes through the through hole,

[0040] - an upper wall which limits the cavity at the top and in which a vertical throughhole is made, for example configured to allow the fixing of a hinge of a toilet seat, wherein the fixing body is inserted into the cavity of the sanitary fixture with an inlet opening of said threaded hole facing the vertical through hole, and wherein the inlet opening and the vertical through hole are misaligned from a top-view viewpoint.

[0041] According to one aspect of the invention, the screw axis may be tilted toward the vertical through hole.

[0042] In light of the above, it is clear that the fastening body also deserves protection in its own right. In this regard, the invention makes available a fastening body in which which comprises:

[0043] - a fixing pin receiving cavity which is provided with a tubular or annular internal surface configured to surround, when in use, at least a portion of said fixing pin,

[0044] - a threaded hole that intersects a portion of the tubular internal surface and defines a screw axis,

[0045] where the threaded hole defines a screw axis that lies on a plane oblique to a central axis of the internal surface.

[0051] DETAILED DESCRIPTION OF THE INVENTION

[0052] The present invention will now be described, for illustrative but notlimitative purposes, according to its preferred embodiments, with particular reference to the attached figures.

[0053] In particular, the reference number 1.1' indicates a sanitary fixture, for example a toilet, of the type configured to be suspended from a wall, i.e. a partition.

[0054] Of said sanitary fixture 1.1', only a rear portion is illustrated in the figures, that is, a portion that when the sanitary fixture is installed is closest to the wall or installation wall. In detail, the sanitary fixture 1.1' comprises a vertical rear wall 5 configured to come into contact with the wall or installation wall, for example equipped with an external vertical face that contacts, preferably directly, the installation wall or installation wall, and an internal vertical face facing in the opposite direction to the external vertical face.

[0055] The sanitary fixture comprises an internal cavity 10 partially delimited by the vertical rear wall 5 and which is open at the bottom when the sanitary fixture is installed, or has a lower opening when the sanitary fixture is installed.

[0056] The cavity is limited above by at least one horizontal upper wall 15 connected to the vertical rear wall 5.

[0057] In the vertical rear wall 5, at least one horizontal through hole 20 is made, for example two horizontal through holes 20, in particular aligned with each other along a horizontal direction. In further detail, the horizontal through hole 20, or each horizontal through hole 20, is rectilinear, preferably orthogonal to the external face of the vertical rear wall, for example also cylindrical. In the horizontal upper wall, at least one vertical through hole 25 is made, for example two vertical through holes 25, in particular aligned with each other along a horizontal direction. In the case in which the sanitary fixture is a WC, the through hole 25 is configured to allow the fixing to the sanitary fixture of a fixing pin belonging to a hinge of a toilet seat (not illustrated in the figures).

[0058] In further detail, the vertical through hole 25, or each vertical through hole 25, is rectilinear, preferably orthogonal to a horizontal upper face of the horizontal upper wall, for example also cylindrical. The sanitary fixture 1,1' may also comprise another vertical rear wall 30 configured in such a way that the internal cavity10 is interposed between the vertical rear wall 5 and the other vertical rear wall 30.

[0059] In the embodiment of the sanitary fixture indicated with the reference 1, the vertical through hole 25 is at least partially aligned vertically with the other vertical rear wall 30 and the horizontal through hole 20 is located at a maximum vertical height lower than a maximum vertical height of the other vertical rear wall 30. In an alternative embodiment not illustrated, the horizontal through hole 20 is located at a maximum vertical height greater than a maximum vertical height of the other vertical rear wall 30, but the difference between said two heights is in any case lower than the maximum vertical extension of a fixing body on which a threaded body is installed, as will be described below.

[0060] In the embodiment of the sanitary fixture indicated with the reference 1 ', the vertical through hole 25 is misaligned aligned vertically to the other vertical rear wall 30, so that a straight tool is inserted vertically from the vertical through hole.

[0061] The sanitary fixture can be fixed to said wall by means of an installation kit, which kit may or may not comprise one or two fixing pins 35 and / or related anchoring devices configured for anchoring said fixing pins to the installation wall or masonry. For example, such anchoring devices (not illustrated in the figures) may comprise or consist of expansion bolts, fixable to the wall, and each of which is associated with a respective fixing pin 35.

[0062] Each fixing pin 35 is a rigid body, for example made of a metallic material, of elongated shape, having a first longitudinal end proximal to the wall or partition and an opposite second longitudinal end distal from the wall or partition, for example of tapered shape, also definable as the free end of the fixing pin itself. In the illustrated embodiment, each fixing pin 35 is substantially cylindrical with a tapered free end.

[0063] Each fixing pin 35 may include a recess 40, for example cone- or funnel-shaped or rounded in shape, which faces upwards when the fixing pin is anchored to the wall. For example, the recess may have a maximum depth of at least halfthe thickness of the fixing pin 35 measured along a vertical direction when the fixing pin is installed.

[0064] In the illustrated embodiment, each fixing pin comprises an axial cavity 41 configured to be fitted onto a rod of the expansion bolt anchored in the wall or partition.

[0065] To fix the sanitary fixture to the wall or partition, the vertical rear wall 5 is fitted onto the fixing pin or pins 35, inserting the pin or pins into the respective horizontal through hole until a portion of said pins (which includes the second longitudinal end) is inside the internal cavity 10.

[0066] Regardless of whether or not the fixing pins 35 are present in the kit, the kit for installing the sanitary fixture on the wall or partition from which the fixing pin 35 protrudes, or the fixing pins 35, comprises a fixing body 45, or a pair of fixing bodies 45, one for each fixing pin 35 in the case where there are two fixing pins 35, configured to be fitted and fixed onto a portion of a respective pin 35 which, having passed through the respective horizontal through hole 20, is located inside the internal cavity 10, so as to prevent the vertical rear wall 5 from slipping off the fixing pin 35, or the fixing pins 35. For example, the vertical rear wall 5 may be interposed, possibly clamped, between the fixing body 45, or the fixing bodies 45, and the installation wall or partition.

[0067] For installation, the fixing body 45 shown in the figures is positioned in the internal cavity 10 before fitting the rear wall onto the pins or fixing pin 35 .

[0068] Each fastening body 45 comprises a (e.g. single) cavity for receiving the respective fastening pin which is provided with, or consists of, a tubular or annular internal surface 50 configured to surround, when in use, at least the portion of the respective fastening pin 35 which is located within the internal cavity.

[0069] Such internal surface 50 may for example be substantially cylindrical, and furthermore the receiving cavity may be through, or may be substantially a through hole. In this case the fastening body may be mainly shaped as a tubular cylindrical body.

[0070] The fastening body 45 comprises a first longitudinal end 46 and a secondlongitudinal end 47 opposite the first along the central axis of the internal surface 50. At the first longitudinal end the fastening body may have an access opening through which the second end of the respective fastening pin 35 is inserted into the receiving cavity, and possibly at the second longitudinal end the fastening body may have an exit opening through which the second end of the respective fastening pin 35 can protrude from the receiving cavity.

[0071] With particular reference to Figures 2 and 3, each fastening body 45 also comprises a (for example only one) threaded hole 55 which intersects a portion of the internal surface 50. In particular, said threaded hole is through and extends from (for example only from) an external surface of the fastening body 45, in which it defines an inlet opening 60, to said internal surface 50, in which it defines an outlet opening 65.

[0072] In use, the inlet opening 60 faces upwards, for example it faces a respective vertical through hole 25.

[0073] The threaded hole 55 defines a screwing axis X that lies on a plane oblique to a central axis Y of the internal surface 50, that is, when the fastening body 45 is fitted onto the respective fastening pin 35 it is oblique to a longitudinal axis Y of the fastening pin itself. In further detail, the screwing axis X can also lie on a plane that contains the Y axis.

[0074] It should be noted that the term "oblique" refers to a geometric entity that is neither parallel nor perpendicularto anothergeometric entity. Therefore, in the present case the plane on which the X screw axis lies is neither oblique nor perpendicular to the Y axis.

[0075] In the illustrated embodiment, the oblique plane of the screw axis X is inclined with respect to a plane perpendicular to the Y axis by an angle between 5° and 30°, for example between 10° and 20°. In the embodiment, this angle is between 13° and 18°. It should be noted that an inclination of 0° would mean parallelism between the plane of the X axis and the plane perpendicular to the Y axis.

[0076] The threaded hole can be made between the first longitudinal end and the opposite second longitudinal end of the fastening body 45, in particular in a halfof the fastening body which includes the second longitudinal end, and the screwing axis can be inclined in the direction of moving away from said first end.

[0077] The fastening body 45 may be a monolithic body, for example made of a polymeric material.

[0078] It should be noted that a monolithic body means a body obtained from the solidification of a single casting, or injection, of (a single) material in a mould and possibly from a subsequent processing of said solidified body by removing material.

[0079] The kit then comprises a threaded body 70 which can be screwed into said threaded hole 55 along the screwing axis X and is equipped with a first end 75, which is external to the internal cavity 10 even when in use, and an opposite second end 80, opposite to the first along the screwing axis and which can be inserted inside the internal cavity 10 following the screwing of the threaded body into the threaded hole, in particular until it contacts a portion of the fixing pin which is located in the receiving cavity, for example in front of the exit opening 65, exerting pressure on it. For example, the second end 80 can be inserted at least partially into the recess 40 and press on a surface of said recess.

[0080] Following the application of said pressure by screwing the threaded body 70 into the threaded hole 55, the fixing pin 35 located in the receiving cavity is pushed against a portion of the internal surface 50 opposite the outlet opening 65 and consequently said fixing pin is clamped between the second end of the threaded body and said opposite portion of the internal surface 50, fixing the fixing body to the fixing pin.

[0081] At the first end 75, the threaded body has a tool portion, i.e. a tool-gripping portion, configured to allow a removable connection of the threaded body itself with a screwing tool capable of imparting the rotation necessary for screwing, and possibly unscrewing, the threaded body. It is also possible to define the first end as consisting of the tool portion.

[0082] Such tool portion may be made as at least one of: a recess or protrusion having a polygonal (regular) cross-section, for example hexagonal, with respect toa section plane perpendicular to the screwing axis, a blade or cross-shaped recess, a Torx® recess , a recess equipped with a plurality of lobes protruding radially with respect to the screwing axis.

[0083] In the embodiment illustrated the tool portion is designed as a hexagonal recess configured to cooperate with an Allen key.

[0084] Thanks to the manufacturing tolerances and dimensional relationships between the tool 81 and the tool portion, for example not different from those of the production of a standard hardware screw and a standard hardware tool to screw such a screw, there is the possibility of screwing the threaded body even when the tool is not perfectly aligned with the X-axis.

[0085] This misalignment, which can be seen in figures 4 and 5, can be increased by means of specific dimensional ratios of the tool portion and / or the tool, and / or particular conformations of the tool portion and / or the tool.

[0086] For example, regardless of the exact shape of the tool portion, if it is a recess, it is preferable that said recess has a depth equal to at least 0.8 times the maximum width of the recess (where the depth is measured along the screwing axis and the maximum width is measured transversely to the screwing axis. If instead it is a protrusion that can be screwed in with a hex key, it is preferable that the height of said protrusion is greater than 0.8 times its maximum width.

[0087] The tool with which to screw the threaded body 70 may be part of the kit. For example, in the illustrated embodiment the kit may include an Allen key 81 one end of which is configured to fit with reduced play into the hexagonal recess of the tool portion.

[0088] In order to increase the versatility and the possibility oftilting the Allen key to reach the tool portion, as an alternative or in addition to the particular dimensional ratios of the tool portion described above, said end of the Allen key configured to fit into the hexagonal recess of the portion may be of a spherical or semi-spherical type, or may comprise an annular groove that creates a narrow section portion a few millimetres (e.g. 2mm - 5mm) from the exact end of the tool.

[0089] The tool portion and the tool of the illustrated embodiment, which forexample features the annular groove, allow for an overall play of approximately + / - 6° with respect to the X-axis.

[0090] Overall, it is therefore possible to screw the threaded body, in the illustrated embodiment, in which the X-axis lies on a plane inclined by approximately 15°, in all situations in which the tool, or a longitudinal axis of the tool, is inclined with respect to the plane perpendicular to the X-axis by approximately 9° up to approximately 21°.

[0091] It cannot be excluded that in an alternative form of implementation not illustrated, always to increase the degrees of inclination, as an alternative or in addition to the particular shape of the end of the Allen key, the recess could have a variable cross-section, with a section that reduces as it goes towards a portion of the bottom of the recess itself.

[0092] Even in the case of other types of tools and tool portions, the ends of the tools and / or the tool portion may have notches and / or countersinks to allow for an increase in the inclination of the tool with respect to the tool portion.

[0093] The threaded body can for example consist of a screw or, as in the illustrated embodiment, of a grub screw.

[0094] The kit may comprise a guide body 85 that can be attached, for example in a removable manner, to the first end of the threaded body and configured to guide the screwing tool towards the tool portion of the threaded body (so the guide body does not obstruct the tool portion) facilitating the coupling of the tool to the tool portion.

[0095] The guide body 85 may for example be shaped like a funnel or hopper or cone, or it may be a tubular or annular body whose cross-section (measured along a plane perpendicular to the screwing axis) decreases as it moves in the direction of approach to the tool portion.

[0096] Alternatively the guide body could be configured as a flexible cylindrical tube .

[0097] Furthermore, the guide body can protrude from the first end in a springlike manner away from the second end of the threaded body. Furthermore, theguide body can be elastically fitted onto the first end of the threaded body. Alternatively, it could be glued or screwed to said first end.

[0098] The kit may also include a centering body 90 that can be associated with the fastening body and configured to center the internal surface 50 of the receiving cavity on the respective fastening pin 35. In particular, the centering body 90 is configured to guide the fastening pin towards the access opening of the receiving cavity and to orient the fastening body, i.e. the access opening of the threaded hole, in a predetermined orientation. This predetermined orientation is the one described above in which the access opening 60 and the tool portion of the threaded body are facing the respective vertical through hole.

[0099] The orientation is obtained by means of a recess or locating device made in the sanitary fixture, or in its rear wall 5, which cooperates with a respective recess or locating device made in the centering body, or when the recess is inserted in the locating device the installer knows that the fixing body is correctly oriented.

[0100] In the present case, in which the fixing body can still be positioned with the inlet opening of the threaded hole facing downwards, or towards the opening of the internal cavity , the sanitary fixture and the centering body together comprise a pair of stops and a pair of recesses opposite each other by 180° in order to allow the fixing body to be installed in the two positions, upwards or downwards.

[0101] The centering body 90 is shaped to be inserted into a respective horizontal through hole 20.

[0102] In the illustrated embodiment, the centering body 90 may for example be shaped like a funnel or hopper or cone, or it may be a tubular or annular body whose cross-section (measured along a plane perpendicular to the screwing axis) decreases as it moves in the direction of approach to the entrance opening of the receiving cavity. Furthermore, the centering body 90 may protrude in a leap from the first end of the fastening body in the direction of movement away from the second end of the fastening body itself. Furthermore, the centering body 90, as occurs in the illustrated embodiment, may be screwed into a threaded portion ofthe internal surface 50.

[0103] The use of the kit according to the invention is as follows.

[0104] The installer can start by partially screwing the threaded body 70 into the threaded hole of the fixing body, so that the second end of the threaded hole remains for the moment outside the receiving cavity of the fixing body.

[0105] If present, the installer proceeds to mount the guide body 85 on the first end of the threaded body and / or to mount the centering body 90 on the fixing body.

[0106] If, as in the illustrated embodiment, there are two fixing pins and therefore two fixing bodies, the above operations must be carried out for both fixing bodies.

[0107] After installing one or two fixing pins 35 on the wall or on the wall, oriented so as to be horizontal and parallel to each other (if more than one), the installer fits the horizontal through holes onto the fixing pins. If the centering body is present, this is previously inserted into the respective horizontal through hole, the fixing body is housed in the internal cavity and from there associated with the centering body. Once the fixing body is connected to the centering body and is in position, the sanitary fixture is fitted onto the fixing pins.

[0108] If the centering body is not present, the installer will have to align the fixing body while the fixing pins are inserted.

[0109] Depending on whether the fixing body has been positioned with the tool portion facing downwards or upwards, the installer acts respectively by inserting the tool from the bottom of the internal cavity of the sanitary fixture or from the vertical through hole proximal to the fixing body.

[0110] Regardless of the orientation of the fixing body, using the tool , the installer screws the threaded body until the second end exerts a predetermined push on the fixing pin, locking the fixing body on the fixing pin.

[0111] It should be noted that in this discussion, when an element is defined as "rigid", it is understood as not being significantly deformable under the normal workloads to which it is subjected. In particular, unlike an element defined as "elastic", a rigid body does not perform its function primarily on the basis of itsown deformation.

[0112] In the foregoing, preferred embodiments have been described and variations of the present invention have been suggested, but it is to be understood that those skilled in the art may make modifications and changes without thereby departing from the scope of protection as defined by the appended claims.
