Definitions

  • the present invention relates to a device for forming a removable, walkabJe floor above a structure to be temporarily covered, wherein the floor is movable between a first position, in which the floor is situated above the structure for covering, and a second position in which the floor is situated adjacently of the structure for covering, wherein the floor is assembled from elements which are mutually separated by separating surfaces extending substantially transversely of the direction movement and wherein the elements can be mutually coupled by couplings adapted to transmit pulling and pushing forces in the direction of movement.
  • Such a device is known from FR-A-2 843 153.
  • the elements can be mutually connected by form-locking couplings which engage or release during a relative vertical movement of the elements but which do allow a movement in the transverse direction, i.e. the direction transversely of the direction of movement.
  • This is related to the fact that in this prior art device the elements are moved along rails which extend along the sides of the structure for covering, in this particular case the swimming pool, and which cause relative lateral movements between the elements due to their forced guiding of the elements.
  • This construction further provides the option of absorbing the mutual shear forces between the elements during loading of the floor, whereby a continuous floor is created with a structure which has structurally the mechanical behaviour of a monolithic floor.
  • the device according to the invention has for its object to provide the option of omitting these rails adversely affecting the appearance of the used structure, such as the swimming pool, which entails that relative lateral movements between the elements cannot always be avoided.
  • the invention proposes to provide such a device wherein the couplings are adapted to prevent relative movements in the direction transversely of the direction of movement.
  • the invention is particularly, though not exclusively, suitable for use on and adjacently of a swimming pool.
  • the swimming pool can hereby be covered so that a safe situation is obtained and contamination or freezing of the swimming pool is prevented.
  • the floor placed on the swimming pool can then be used as terrace, dance floor or sports surface, also depending on the nature of the floor. It is however also possible to apply the floor elsewhere, i.e. not on a swimming pool. It is possible here to envisage tennis courts, so that tennis can be played on a 'smash court' in winter and on a classic gravel court in summer.
  • the invention can also be applied indoors, again not only on a swimming pool but also to provide a dance floor or for instance squash courts.
  • the couplings each comprise a magnetic circuit, a first part of which is situated in a first element and a second part of which is situated in an adjacent element, wherein the magnetic circuit comprises at least one magnet.
  • the magnetic couplings allow a play in the lateral and perpendicular direction. They are moreover not subject to wear. It is noted here that the magnetic coupling, in combination with the application of heavy, for instance concrete elements, has the advantage that during stacking the magnetic coupling can be broken without further aids as result of the action of the force of gravity.
  • the magnet is a permanent magnet.
  • the energy consumption can hereby be greatly reduced since no energy is used when the coupling is active.
  • an electromagnet is preferably incorporated in the magnetic circuit
  • the magnets are preferably mounted on the elements for tilting at least through a small angle about a horizontal axis on one side of an element.
  • This separation takes place in the direction known in mechanics as the shear S direction.
  • the force necessary to separate the magnets from each other is already fairly small in this direction.
  • the tiltable magnet will tilt during the relative movement of the magnets in vertical direction, whereby the contact surfaces of the magnets are separated from each other and the force required to separate the magnets still further is reduced even more. In this embodiment0 it is thus not necessary to deactivate the electromagnets.
  • the tiltable magnets are encased in a housing of flexible material.
  • the couplings are form-locking in the5 horizontal direction transversely of the direction of movement.
  • a simple method is herein provided for transmitting shear forces in horizontal direction between the elements.
  • the elements are adapted to engage through0 relative movement in vertical direction of one of the elements relative to an adjacent element. This measure does after all provide the option of directly coupling the elements to each other during unstacking and of uncoupling them during stacking. This latter embodiment becomes even more attractive when the couplings are adapted to block relative vertical movement between the elements when they are moved toward each other in horizontal direction.
  • the mechanical behaviour of a monolithic floor is hereby approximated best.
  • a preferred embodiment of the invention therefore provides the option that the elements are each provided with at least four wheels, and that the wheels are adapted to roll over the edge of the swimming pool, whereby rails are no longer necessary.
  • wheels it is in principle also possible to make use of magnetic levitation. Magnets are preferably used here which are only active during the movement of the elements, and which can thus be deactivated by being moved from their active position to a passive position.
  • the relation to a terrace which is usually arranged around the swimming pool is important. It is possible here to bring the water level of the swimming pool to the same level as the terrace. Because the cover according to the invention has a certain height, the cover will then inevitably protrude above the level of the terrace. It is of course possible that the upper surface of the cover coincides with the level of the terrace, which results in an attractive appearance in the closed position of the cover. It is then however not possible to bring the water level close to that of the terrace.
  • the cover hereby forms as it were a new terrace, which extends at least partially over the fixed terrace.
  • This embodiment is important particularly, though not exclusively, when the swimming pool has for instance a non-rectangular form or when the swimming pool is placed indoors and the space in question is wholly covered by the cover. This can also be solved by displacing the swimming pool in vertical direction through a distance corresponding to the height of the cover.
  • the pit in which the elements can be stored is covered by an element which lies at the same level as the surrounding surface, so that it does not protrude upward.
  • the elements each comprise a self-supporting concrete construction. Due to its great rigidity this embodiment moreover provides the option of covering the element with metals, natural stone, glass, artificial grass, plastics, tiles or another ceramic material which is the same as the material with which the surrounding surface or underlying structure is covered. In order to save weight, it is recommended that the elements are manufactured at least partly from high-strength concrete with a compression strength greater than 65 MPa.

Abstract

L'invention porte sur un dispositif pour former un sol sur lequel on puisse marcher, par exemple, au-dessus d'une piscine, le sol étant mobile entre une première position dans laquelle le sol est situé au-dessus de la piscine, et une seconde position dans laquelle le sol est situé de façon adjacente à la piscine, le sol étant assemblé à partir d'éléments qui sont mutuellement séparés par des surfaces de séparation s'étendant sensiblement transversalement au mouvement de direction, et les éléments pouvant être mutuellement couplés par des couplages capables de transmettre des forces de traction et de poussée dans la direction du mouvement, les couplages étant capables d'empêcher un mouvement relatif dans la direction transversalement à la direction du mouvement. L'utilisation de rails non attractifs à côté de la piscine dans le but de guider les éléments peut ainsi être évitée.
