Definitions

  • the present invention relates to a device for forming a series of perforations in a mattress layer, which device at least comprises a punch provided with punching pins arranged in a specific matrix pattern and positioned opposite a piercing die provided with holes arranged in rows and columns according to the same matrix pattern, in line with the aforesaid punching pins, wherein the diameter of the holes on the side facing towards the piercing die is larger than the diameter of the punching pins.
  • the present invention furthermore relates to a method for forming a series of perforations in a mattress layer, using such a device; as well as to an upper mattress made of latex foam. More in particular, the present invention relates to the use of such an upper mattress.
  • perforations in the mattress layer can enhance the comfort of the person lying on the mattress and improve the moisture discharge of the mattress, in which connection it can be mentioned in particular that people on average secrete up to 1 litre of sweat a night while sleeping. Said moisture is discharged into the surrounding atmosphere as a result of a good ventilation of the mattress, which in itself makes the mattress feel drier, which in turn enhances the sleeping comfort of the user of the mattress. If a moist mattress is insufficiently provided with moisture-discharging means, the mattress will be susceptible to fungoid growth. The provision of additional ventilation in the mattress gives the mattress a higher sense of comfort, and in addition ensures a longer life of the mattress. Furthermore it is known in that people make frequent movements while sleeping, and the shifts in the body weight on the mattress produce a so-called pumping movement, which in turn leads to a satisfactory ventilation and transmit of the moisture.
  • the aforesaid perforations are usually provided according to a specific matrix pattern in the mattress layer, either over the entire surface area of the mattress layer or only in specific zones, after the latex layer has been formed.
  • Latex foam of itself has a unique open cell structure, which means that millions of microscopically small interconnected air bubbles in the latex foam provide a good ventilating effect.
  • moulding elements such as waffle irons are used, with latex foam being poured into a closed mould provided with aluminium pins to ensure a good heat conduction, and subsequently being vulcanised, washed and dried into an end product.
  • the mattress the end product
  • the mattress comprises vertical, continuous recesses that ensure a proper ventilation of the mattress.
  • mattresses having a thickness of up to 20 cm can be produced, with the thickness mainly being limited by the speed at which the heat can be introduced into the core of the latex material.
  • the second method for producing latex foam according to the well-known Dunlop process is the pouring of latex foam on an endless conveyor belt, followed by vulcanisation, washing and finally drying.
  • the maximum height of the mattress built up of latex foam is approximately 5 cm, because heat cannot be introduced into the core of the latex material sufficiently quickly due to the absence of aluminium pins on the conveyor belt.
  • the latex plate that is obtained does not have any vertical, continuous channels.
  • the mattress plate is provided with perforations.
  • the prior art devices for forming such perforations consist of a punch provided with punching pins arranged in a specific matrix pattern on a punching block and positioned opposite a piercing die provided with holes arranged in the same matrix pattern, in line with the aforesaid punching pins.
  • the piercing die of these known devices comprises as many blocks as there are holes, each block being provided with only one hole, which blocks are arranged in rows and columns in a common framework.
  • a first aspect of the present invention is to provide a method and a device for forming a series of perforations in a mattress layer, in which perforations are formed in the mattress layer in such a manner that said perforations are spaced considerably more closely than has been possible so far in the prior art, and that without the reliability of operation of the device being affected.
  • Another aspect of the present invention is to provide an upper mattress which exhibits very favourable characteristics as regards the comfort of the person lying on the mattress and the moisture discharge.
  • Another aspect of the present invention is to provide a method and a device for forming a series of perforations in a mattress layer, in which an upper mattress is obtained whose closed cell structure is visible at the upper side and the lower side thereof.
  • the present invention as referred to in the introduction is characterized in that the piercing die is substantially composed of one or more solid die blocks, each provided with several holes.
  • An advantage of a device according to the invention is the fact that a piercing die comprising several holes in one and the same solid die block is much more robust than in the known devices, as a result of which the holes in the piercing die can be spaced relatively closely, making it possible when using such a device according to the invention to realise mattress layers provided with perforations which can be spaced relatively closely at need.
  • the holes extend all through the thickness of the piercing die, with the diameter of the holes increasing over at least part of the thickness of the piercing die, in the direction away from the punch.
  • the parts being punched out of the mattress can easily be discharged from the holes in the piercing die.
  • the holes extending from the side facing towards the punch prefferably have a constant diameter in a first part of the thickness of the piercing die and a larger diameter in a second part of the thickness of the piercing die. Since the holes have a constant diameter over a particular thickness from the side where the punching operation takes place, the piercing die can readily absorb the forces that are transferred thereto during a punching operation. The parts that have been punched out of the mattress can subsequently be discharged from the mattress in the part having the larger diameter.
  • the diameter of the holes on the side facing towards the punch ranges between 3 and 8 mm, in particular between 4 and 6 mm, so that a mattress is obtained which is quite comfortable in use. If a diameter of less than 3 mm is used, the holes that have been punched out of the mattress layer will hardly be visible from the upper side of the mattress. Due to the compressible nature of the mattress, the holes will close at the upper side, whilst they will remain visible to a certain extent at the bottom side. This phenomenon is caused by the fact that the holes in the mattress are conical in shape.
  • the holes further extend at a constant diameter in the remaining part of the thickness of the piercing die towards the side of the piercing die remote from the punch.
  • the diameter of the holes on the side remote from the punch ranges between 8 and 12 mm.
  • sufficient space is thus obtained between a punched-out part of the mattress and the punching pins, and on the other hand a robust surface is obtained on the side of the piercing die remote from the punch.
  • the spacing between two adjacent rows and/or two adjacent columns of the holes in the piercing die of the die block is less than 20 mm, preferably it ranges between 12 and 13 mm.
  • a narrow spacing between holes in a mattress, which can be achieved in this manner, provides a higher degree of comfort than a wider spacing between the holes.
  • the punching pins are connected to the punch in such a manner as to be pivotable with respect to the punch, so that sudden forces will not lead to fracture of the punching pins.
  • the free ends of the punching pins facing towards the piercing die are constructed in such a manner that the distance measured between the free ends of the punching pins and the corresponding holes in the piercing die is not constant.
  • the pins move simultaneously into the corresponding die holes when the punch comprising the punching pins is moved in the direction of the piercing die, so that the force that must be exerted by the device during the punching operation is distributed over the contact surface between the punching pins and the die holes.
  • the period during which a force must be exerted is prolonged, to be true, but the duration of the peak load is reduced.
  • the surface facing towards the punch of at least one of the die blocks is preferably recessed in relation to the surface facing towards the punch of at least one of the other die blocks.
  • not all the punching pins have the same length. Such differences in length may occur within one and the same punch, or different lengths may be used for different punches. In this way, the same result as discussed in the preceding paragraph is obtained in a simple and practical manner. This aspect can also be applied in existing devices having flat piercing dies.
  • guide means are provided between points of attachment of the punching pins on the one hand and the piercing die on the other hand, through which guide means the punching pins extend so as to be guided into the associated holes when the punch is being moved in the direction of the piercing die. Said guide means ensure that the punching pins are directly exactly towards the corresponding holes, thus reducing the risk of damage or wear between a punching pin and a corresponding hole.
  • the punching pins partially extend through the guide means. Since the punching pins are accommodated in the guide means, they reciprote through said guide means during operation of the device, as it were, so that they are prevented from making undesirable movements or, in an unfavourable situation, moving out of the guide means.
  • the method for forming a series of perforations in a mattress layer, using the present device is characterized in that the method comprises the following steps:
  • steps ii)-iv) after completion of step iv), with steps iii)-iv) being carried out in specific zones of the mattress layer.
  • step i) In order to obtain an optimum comfort of the person lying on the mattress and a satisfactory discharge of moisture, it is preferable to provide a mattress layer in step i) in which specific zones at the upper side of the upper surface of the mattress layer are profiled.
  • the free ends of the punching pins do not all reach the associated opposite holes in the punching die simultaneously in step iii). This has the aforesaid advantage that the force that is to be exerted by the device is distributed over a certain period.
  • the free ends of the punching pins preferably extend at least into the portions of the holes having the larger diameter at the end of step iii).
  • the parts of the mattress that have been punched out of the mattress are now pushed past the widened portions by the punching pins and can thus be easily discharged.
  • the punching pins permanently extend through the guide means while the steps i)-iv) are being repeated.
  • the perforations are formed in the mattress in a pattern of rows of perforations and/or columns of perforations, the spacing between two adjacent rows of perforations and/or columns of perforations being less than 20 mm, preferably it ranges between 12 and 13 mm. As already discussed before, this gives the user of the mattress a higher degree of comfort.
  • the improved upper mattress according to the present invention which upper mattress is made of latex foam, is characterized in that the vulcanised layer of latex foam is provided with perforations in at least one zone of the upper surface thereof and with a profile in at least one zone of said upper surface.
  • the aforesaid perforations are formed in zones near those parts of a user's body that secrete the most sweat, mainly the neck, the back and the thighs.
  • the advantage of this is that the body moisture can be discharge directly via the aforesaid perforations, which is achieved in part as a result of the changes in the user's position, which produced movements of air through the perforations, thus effecting a natural ventilation of the upper mattress.
  • the perforations thus prevent moisture remaining accumulated within the mattress too long, which might lead to fungoid growth and further unpleasant effects.
  • the profiles present in specific zones at the upper side of the upper layer of the mattress enhance the sleeping comfort of the user, because the mattress feels softer in said zones, depending on the shape and the dimensions of said profiles.
  • zones comprising perforations alternating with zones comprising profiles will lead to an upper mattress which meets each and every requirement of an exacting user as regards sleeping comfort.
  • Special embodiments of the present upper mattress are defined in the subclaims.
  • Figures 1-4 show a device according to the invention, which mainly consists of a table 1 having upright side edges 2; a driving mechanism 3 in the form of two rollers 4 and 5, respectively, which are arranged in spaced-apart relationship a certain distance above the top of the table 1, and which are mounted in supports 6-7 positioned opposite each other on either side of the table 1, the roller 5 being driven by a motor 8; a punching device 9, which is positioned near a transverse recess 10 in the table 1 between the aforesaid rollers 4-5, and which extends across the width of the table 1; and a cutting device 11, which is disposed some distance away from the roller 5 at the location of a second transverse recess in the table 1.
  • the punching device 9 mainly consists of a stand 12; a punch 14 suspended from said stand 12 by means of a hydraulic or motor-driven cylinder 13, which punch is provided with a series of punching pins 15 arranged in a specific matrix pattern, and a piercing die 16 positioned opposite said punch 14, which is attached to said stand by means of a framework 17, in such a manner that the upper surface of the piercing guide 16 lies in the same plane as the upper surface of the top of the table 1.
  • the piercing die 16 is made of one solid die block 18 in this case, in a special embodiment five such solid die blocks may be used, each provided with several holes 19 in line with the aforesaid punching pins 15, more specifically in the same matrix pattern as the punching pins 15, comprising a relatively small number of rows 20 extending across the width of the table 1 and a relatively large number of columns 21 extending in the longitudinal direction of the table 1.
  • the device is disposed at the end of the production line for manufacturing a continuous mattress layer 22 of latex foam or the like, in which, as is shown in Figures 1 and 2, the mattress layer 22 is moved over the table 1 between the punch 14 and the piercing die 16 by the driving mechanism 3, more in particular by the driven roller 5.
  • the motor 8 of the driven roller 5 is stopped temporarily each time a series of perforations 23 is to be provided in said continuous mattress layer 22, so that the mattress layer is held in a fixed position, after which, as is shown in Figure 4, the cylinder 13 of the punching device 9 is driven to move the punching pins 15 downwards into the underlying holes 19 of the piercing die 16, so that the punching pins 15 are driven through the mattress layer 22 in a manner which is known.
  • the punch 14 is moved upwards again, after which the mattress layer 22 is moved a suitable distance ahead over the table 1 by means of the driving mechanism 3 and the punch 14 is moved downwards again in order for a next strip to be punched.
  • the continuous mattress layer 22 is provided with perforations 23 strip after strip in a semi-continuous process.
  • Pieces 24 of the perforated mattress layer 22 are cut to the desired length by means of the aforesaid cutting device 11, which pieces 24 can subsequently be used in the production process for composing mattresses.
  • piercing die 16 is made of one solid die block 18 is that this makes it possible to space the holes 19 of the piercing die 16 relatively closely, as a result of which perforations 23 arranged in a relatively dense matrix pattern can be realised with one single punching movement, which may be advantageous in particular cases in connection with the comfort of a person lying on a mattress provided with such a piece of perforated mattress layer 24.
  • the punching pins 15 When the punching pins 15 are connected to the punch 14 in such a manner as to be pivotable with respect to the punch 14, with the punching pins 15 extending through guides (not shown) in the direction of the mattress layer 22 and the piercing die 16, the punching pins 15 and the holes 19 in the piercing die 16 can be spaced even more closely.
  • the pieces of mattress layer 24 are shown to be provided with perforations 23 over the entire surface thereof in the Figures, it is quite possible to provide such pieces of mattress layer 24 with perforations only in specific zones in alternative embodiments, with zones provided with perforations and zones not provided with perforations arranged in alternating relationship, in which case the punch 14 and the piercing die 16 do not necessarily have to extend across the entire widh of the mattress layer 22 to be perforated. Preferably, however, the piercing die 16 will extend across the entire width of the zone of the mattress layer 22 that is to be perforated.
  • Figure 5 shows a variant of a piercing die 16 according to the invention, in which the piercing die 16 is composed of several solid die blocks 18, each provided with holes 19 arranged in a matrix comprising several rows and columns of holes, which are arranged side-by-side in a continuous row in a common framework 17.
  • the piercing die 16 as shown in Figures 5 and 13 is composed of several massive die blocks 18, it is possible to position a die block 18' with the surface facing towards the punch 14 in a recessed position.
  • the punching pins 14 will all come into contact with the mattress layer 22 simultaneously in that case, to be true, but because not all the punching pins 15 move into the corresponding holes 19 simultaneously, the force to be exerted by the punch 15 is distributed over time, as a result of which the peak load for the device is reduced.
  • FIG. 14 Another possibility of achieving this is shown in Figure 14.
  • Said figure shows a punch 14' fitted with punching pins 15' that vary in length.
  • the various punching pins 15' not only enter the holes 19' of the piercing die 16' at different points in time, but they also come into contact with the piercing die at different points in time.
  • the effect that is achieved in this manner is comparable with the embodiment of Figure 15.
  • a piercing die 16 may also be composed of die blocks 18 comprising several aligned holes 19, which may form part of a respective row or column of the matrix pattern of the piercing die 16.
  • Figures 12a and 12b show special embodiments of a piercing die 16, in which the diameter A of the holes 19' on the side facing towards the punch 14 is smaller than the diameter B of the holes on the side remote from the punch 14.
  • a hole 19' first extends over a distance X from the upper side of the piercing die 16 that faces towards the punch, over which distance X the diameter remains constant, viz. A. Subsequently, the diameter of the hole 19' increases over a distance Y in the direction of the side of the piercing die 16 remote from the punch 14.
  • the hole 19' extends over a distance Z up to the side of the piercing die 16 remote from the punch 14, over which distance the diameter of the hole 19' remains the same, viz. B.
  • the values of A and B may vary from 4-6 and from 8-12 mm, respectively. Also the values of X, Y and Z may vary.
  • the advantage of using holes 19' having a shape as described above is that mattress material that has been punched through the upper side of the die 16 can exit the hole in the die without getting stuck between the walls of the hole 19'.
  • Figures 12a and 12b furthermore show the spacing between two rows and between two columns c and d, respectively, which is 12.5 mm in this case.
  • Figure 15 finally shows the situation in which the punching pins 15 are in their lowermost position in the corresponding holes 19 of the piercing die 16.
  • the figure clearly shows that the punching pins extending to within the widened portion of the holes 19, as a result of which mattress material that has been punched out of the mattress by the punching pins 15 via the upper side of the holes 19 can exit the die 16 without getting stuck inside the holes 19.
  • FIGS. 6 and 7 schematically show an improved upper mattress according to the invention in the simplest form thereof.
  • the layer 1 is a rectangular layer of latex foam having a specific thickness.
  • the upper surface 2 of the layer 1 is provided with profiles 4 in particular zones 3, for example in the form of corrugations extending in the crosswise direction of the layer 1, over the entire width thereof, with perforations 6 being provided in the intermediate zones 5, which perforations form a connection between the upper surface 2 and the lower surface 7 of the layer 1, with the zones 3 and the zones 5 thus alternating in the longitudinal direction of the mattress.
  • Figures 8 and 9 show an embodiment of a mattress, in this case consisting of two layers arranged one on top of the other, viz. an improved upper mattress or layer 1 of latex foam as described above, and a full lower layer 8.
  • Figure 9 clearly shows that the zones 2 provided with perforations 6 are located near those parts of a user's body 9 where the user secretes the most sweat, viz. the neck 10, the back 11 and the thighs 12. At these locations the bodily fluid is indeed directly discharged in downward direction through the perforations 6, so that the latex foam layer 1 that is in contact with the user's body 9 will remain dry at all times, and consequently will not be affected by fungoid growth or the like.
  • the varying thickness of the layer 1 in the profiles zones 3 makes the mattress feel softer or harder in said zones 3, as desired, depending on the shape and the dimensions of the corrugations.
  • Figures 10 and 11 show a variant of an embodiment of a mattress in which, in this case, the improved upper mattress or layer 1 of latex foam is arranged on top of an elastic lower layer 13 composed of spring elements 14 arranged in side-by-side relationship, for example in the form of metal coil springs, elastic elements of plastic material or the like, in which case a protective layer 15, for example in the form of a mattress ticking made of a layer of a textile such as felt, jute or the like, is preferably arranged between the layer 1 of latex foam and the lower layer 13.
  • a protective layer 15 for example in the form of a mattress ticking made of a layer of a textile such as felt, jute or the like, is preferably arranged between the layer 1 of latex foam and the lower layer 13.
