    SHIELD COMPOSITION
    The present invention relates to a hatch assembly for a glass surface of a display holder, such as a display case or window box, for protecting against grit removal by impacting the glass surface. The present invention further relates to a method for using the hatch assembly. Combined with this, the present invention relates to a display case, display window or glass frame.
    For displaying valuable objects, cabinets or spaces are often used that are protected by glass so that items displayed behind the glass can be properly perceived by the public. A disadvantage of this glass is that it is fragile and therefore that the valuable objects are accessible for removing them when the glass is broken.
    As a result, the safety of the valuable objects is at stake. A common problem is that through hit and run activities the valuable objects can be removed very quickly by breaking the glass.
    To prevent this, the present invention provides a hatch assembly for a glass surface of a display holder, such as a display case or display window, for protecting against gris removal by impacting the glass surface, the assembly comprising: - a hatch comprising a composite set of hatch slats, - guide means for guiding it or keeping it in a closed state during a movement of the hatch between a pre-adjustable open state and a closed state, - actuating means for actuating the movement from a stationary state, wherein - the hatch assembly is adapted to protecting the display holder by, upon actuation of the hatch, causing it to move downwards or sideways from the open state to the closed state under the influence of a potential force, such as gravity or a spring force.
    Using a hatch assembly according to the present invention, the unwanted removal of the objects are effectively prevented because after hatching the hatch closes completely within zero to a few seconds, so that, if the glass is acted upon quickly after breaking, there is insufficient time for removal after breaking the glass. According to a first preferred embodiment, the hatch assembly comprises retaining means, such as braking means, for holding the hatch in the open position by retaining the potential force. By using such restraining means, the trap door can be kept under the influence of gravity in a state that it will immediately fall. As a result, the trap door does not have to be driven to close it. Furthermore, only the restraining means need to be activated for closing the hatch so that it can react very quickly and the movement can be very fast.
    According to a further preferred embodiment, the hatch assembly comprises ballast means for urging the hatch downwards under the influence of gravity. An advantage of such ballasting means is that frictional forces that obstruct the movement are thereby overcome and therefore the movement can be reliably used. A further advantage of such ballasting means is that the assembly can be of relatively compact design, since the underside of the hatch, when the hatch is in a rolled-up state, can be of relatively short design. The hatch assembly furthermore preferably comprises driving means for driving an initial movement of the hatch. Here too the friction for the movement can be overcome. Furthermore, it is possible to arrange the hatch completely rolled up in a housing so that it takes up little space during use and / or can be arranged completely in a housing.
    More preferably, the pre-adjustable open condition of the hatch is defined as being arranged on a roll with a portion extending downwardly from the roll with a sufficient weight that the hatch will start moving towards the closed condition under the influence of gravity only. As a result, the roll need only be prevented from unrolling under the influence of gravity, which provides an advantageous construction of the device.
    According to a further preferred embodiment, the hatch assembly comprises block path means for blocking upward movement of the hatch assembly. An advantage of such blocking means is that the hatch of the hatch assembly can be fixed in the closed state, at least only difficult to open or can only be opened using tools. This is of great importance in practice for protecting objects, since time is an important factor in protecting valuable objects.
    In such embodiments, the blocking means are preferably arranged as a guide slot with at least partly a format such that slats can fall obliquely therein so that the slats, preferably at least in an upward direction, obtain a self-locking action when pushed upwards. The operation is as follows. When a slat from the front to the back or from the back to the front is skewed in the channel, this causes a high friction when attempting to push the slats upwards.
    Certainly when a number of slats are skewed in the channel above one another, this frictional force cannot be overcome by pushing. Only by pulling the hatch from above is the slat again in vertical orientation in the slot and can the hatch be pulled up instead of being pushed up. It is sufficient if part of the channel has the greater depth. A slat that is skewed at the location of the transition from a greater depth will block this transition.
    The blocking means are preferably arranged as a ratchet assembly, suitable for allowing the movement from the open state to the closed state and for blocking the movement from the closed state to the open state.
    The blocking means are furthermore preferably achievable by activating the retaining means when the hatch is in the closed state. In a further preferred embodiment, the hatch assembly comprises a brake assembly, the brake assembly preferably comprising means for electromagnetically releasing a brake disc or shoe. Such a brake assembly is of compact design in the axis direction of a subsequent trap door. This allows multiple shutter assemblies with a short spacing to be realized.
    The brake assembly furthermore preferably comprises a brake disc which can be blocked under bias, preferably which bias can be canceled by electromagnetic means to actuate the movement. An advantage of such an assembly is that the movement can be actuated by means of an electrical signal, and therefore by means of a manual or automatic actuation. This also makes it possible to realize a compact construction of the brake assembly.
    For the purpose of opening the trap door, the hatch assembly in a further preferred embodiment comprises a drive assembly for bringing the hatch from the closed position to the open position, preferably comprising a gear wheel and a screw or worm for driving the gear wheel. This makes the trap door reusable after a shutdown event. The drive of the drive assembly preferably comprises a coupling member for coupling with a drive attachment. An advantage of this is that without an accessory the hatch cannot be opened, whereby extra safety can be realized. A person who wants to open the objects is confronted with the lack of the accessory and cannot open the hatch. Mounting the attachment takes time. When a person knows that the attachment is needed and is stored remotely and therefore the hatch cannot open after it is closed, no attempt will be made since this is meaningless. As a result, such offenses are prevented altogether by clearly indicating that the hatch will close and cannot be opened.
    Alternatively, or additionally, the drive of the drive assembly is protected by means of a lock or a code, more preferably wherein drive of the drive assembly preferably comprises electronic receiving means for receiving an activation signal from a remote location. It is important here that once the hatch is closed, the hatch cannot be reopened without outside assistance.
    According to a further preferred embodiment, the hatch assembly comprises a glass break detector for detecting breakage of the glass. This realizes that the hatch can be closed immediately when the glass is broken. The system preferably further comprises a detector for detecting whether a glass door is closed. Such a detector is important to prevent the trap door from falling down while the door is legitimately open, such as when it is opened by means of a key from a staff member.
    For the purpose of compact assembly of a series of hatch assemblies, the retaining means and the block quay means can each be mounted on both sides of the hatch. This allows the shutters to be mounted relatively close to each other.
    For the purpose of preventing hand, wrist -1 or arm fracture, the hatch assembly comprises a stop for terminating the movement substantially at the open position. With a suitable mounting of this stop above a bottom of the display holder, an optimum position of the underside of the hatch in the closed condition can be determined in advance. This can prevent us from accidentally lowering hatch parts of the body from being damaged.
    In a further preferred embodiment, the hatch assembly comprises a hatch motor, preferably embodied as a tubular motor, arranged essentially in the center line of the hatch in a rolled-up state, and a power supply connector suitable for maintaining the power supply, or for reconnectable disconnecting the power supply, while allowing the hatch to move under the influence of the potential force. This makes it possible to simply roll up the hatch again after it has been lowered under the influence of the potential force to an open state. Furthermore, a general use as a security hatch for opening and closing with application of the closure under the influence of the potential force is possible. Even after the violent closing due to the potential force, the motor remains usable for re-opening and re-closing the hatch using the motor.
    According to a further embodiment, in the hatch assembly the current supply here comprises a drag coupling or a plug coupling. A drag coupling has the advantage that it is always usable. A plug-in coupling 1 provides an economically manufacturable electrical connection, but requires a mechanical re-coupling after a potential force closure, often in a manual manner. Further aspects according to the present invention relate to a hatch assembly display case, a hatch assembly display window, and / or a hatch assembly glass frame, comprising a hatch assembly according to the present invention. Such aspects have advantages as described in the above.
    A further aspect according to the present invention relates to a method for securing a flat surface of a display holder, such as a display cabinet or display compartment, comprising steps for providing a hatch assembly according to one or more of the preceding claims. This aspect has advantages as described in the above.
    Further advantages, features and details of the present invention will be described in greater detail below with reference to one or more preferred embodiments with reference to the attached figures. Similar but not necessarily identical components of different preferred embodiments are designated by the same reference numerals.
    FIG. 1 is a front view of a first preferred embodiment of the present invention in the open state.
    FIG. 2 is a front view of the first preferred embodiment of the present invention in the closed state.
    FIG. 3 relates to a detail of the first preferred embodiment.
    FIG. 4 and 5 relate to further details of the first preferred embodiment.
    FIG. 6 relates to a further preferred embodiment with lateral movement of a hatch.
    FIG. 7 relates to two representations A, B of a further embodiment with a tubular motor and an electrical coupling.
    A first preferred embodiment (Fig. 1, 2) according to the present invention relates to a trap door assembly 1. This comprises a hatch 2 composed of a series of slats. The slats can be made of a metal or plastic. The slats are mutually coupled such that a roll-up hatch is provided.
    The assembly further comprises a support frame 3, 3 'which is provided on its underside with U-shaped, slot-forming profiles 4, 4' facing the open side towards each other for guiding the slats. In FIG. 1, the hatch is rolled up about the shaft 6, 6 ', around a hatch drum 9 (see Fig. 2).
    Block-lashing means 30 are arranged on the left-hand side, in this preferred embodiment designed as a holding brake. This assembly is described in greater detail with reference to Figs. 3. On the right-hand side there is a drive assembly 50 for bringing the hatch from the closed position to the open position, in the preferred embodiment comprising a gear and a worm for driving the gear. This assembly is described in greater detail with reference to Figs. 4.5.
    The hatch is kept in the open position by means of the holding brake. The in FIG. 1 visible lower slats provide sufficient weight under the influence of gravity to unroll the roll downwards upon releasing the holding brake. Therefore, when the holding brake i is actuated for release, the trap door will fall down rapidly under the influence of gravity.
    Viewed in top view, the slot has such a large distance between the ends of the legs of the U that the slats in the slot are slanted. This makes it impossible to push the slats upwards because of the high frictional force that is thereby provided. It is, however, possible to pull the hatch upwards by rotating the shaft 6, 6 'and thus to wrap it around the drum 9 again. In FIG. 3, the assembly 30 comprising the holding brake is shown in greater detail in section. A housing comprising a cover plate 36 and a shell 36 'encloses the brake. The housing is attached to the frame 3 'of the trap door assembly by means of at least one bolt 8. The shaft part 6 'is mounted by means of bearing 41 in the housing and mounted by means of the fixing member 37. The operation is as follows. Under the spring force of the spring 38, the anchor disk 42 is pressed against the brake disk 31 which is provided on both sides with a friction layer 32. The brake disc is hereby also pressed against the cover plate 36, whereby the brake is blocked and the shaft 6 'cannot rotate. When the coils 39 are supplied with an electrical voltage, a magnetic field is built up with which the anchor disk is attracted to the coil. This releases the brake disc, which allows the shaft to rotate freely. It will be clear that when the shaft can rotate freely, the hatch can fall down. The hatch is actuated by switching on the electrical voltage to the coils. This preferably occurs when a window is smashed and a glass break detector detects it and immediately generates a signal for switching on the voltage to the coils 39. This describes the operation of lowering the hatch of the preferred embodiment.
    With reference to FIG. 4 and 5, the raising of the hatch again is described in more detail. Fixed to the shaft, a gear 52 is provided from the outside with teeth 53. Furthermore, the shaft 6 is mounted on the bearing block 58 which in turn is mounted on the frame 3.
    A worm assembly 51 is also mounted on the frame part 3. The worm 63 contacts the teeth 53. A worm 61 is rotatably mounted therein. Attached to the worm is an insertion member 62 for inserting therein a drive means for driving the worm. For moving the hatch upwards by rotating the shaft by rotating the worm, a driving aid must be inserted into the plug-in member 62.
    It is a conscious aspect of the present invention that an attachment is required for this drive. The intention is that the moment the hatch is moved downwards, it can no longer be moved immediately upwards, so that the valuable objects cannot be reached.
    For the purpose of activating the hatch, in this preferred embodiment by providing an electrical voltage on the coils 39, a control is provided with an uninterrupted power supply, with inputs for signals originating from the glass-broken detectors and outputs for the providing the electrical voltage to the coils 39. Alternative inputs for the control are activation buttons that can be activated by personnel. Further alternative inputs for control are input signals from an alarm system.
    In FIG. 6 A and 6 B, a further preferred embodiment of the present invention is shown. This | variant has a hatch 2 which is moved in the horizontal direction under the influence of a potential force after actuation by actuating means. The concept of this embodiment is aimed just as with other embodiments that a sustained potential force is available which is restrained by restraining means, such as braking means. The advantage of this is that a very fast response time is achieved for the actuation and subsequent movement of the hatch from the open to the closed position. The embodiment is described below with reference to a vertically arranged, horizontally sliding device. However, the inventor has also provided a horizontally arranged variant that shifts horizontally. Here, the shafts are arranged horizontally, and in the closed state the hatch is arranged substantially just below the plane of a horizontally arranged display glass plate or a counter glass plate.
    Shown is a cabinet 64 comprising a front wall with a glass panel 70 or assembly of glass panels arranged therein, two side walls 67, 68 and a rear wall 69. The cabinet is shown in plan view with an upper wall omitted and in section. Along the walls 68 and 66, guide means 71, 72 are arranged for guiding the hatch 2. In the opened state, the hatch is arranged at least partially around a winding shaft 65.
    The hatch extends from the winding shaft along the side wall 68 in the guide. The hatch further extends around a corner axis arranged in a corner of the walls 66,68, which axis serves to guide the hatch 2 around this angle. In the opened condition, an edge 81 of the hatch is in the vicinity of this corner axis or between the corner axis and the glass part 70 of the wall.
    Cables 76, such as steel cables or fiber-reinforced cables, are attached to the edge 81 for connecting them to a drive shaft 9, which is arranged in the angle between the walls 67 and 69. These cables are guided for this purpose around guide rollers 75 arranged on axis 74 in the corner of walls 66 and 67.
    A drive assembly 30 'of the shaft is provided with blocking block means similar to those used in the gravity embodiment described above. This keeps the hatch permanently braked against closing. The drive assembly is furthermore provided with a drive for keeping the hatch closed by means of the cables 76 under a continuous bias for tensile closing. To this end, a spiral spring is provided in this embodiment which can bring about sufficient rotation of the shaft for winding up the hatch. cable translating the hatch horizontally along the length of the glass plate 70 in the front wall 66.
    Because the cables and thus the hatch are kept under a sustained pre-tension of the spring, the hatch can be closed by releasing the brake at the instigation of a glass break sensor from the glass plate. As a result, an immediate closure is achieved and there is a comparable time delay as with the gravity variant. It is hereby realized that the closure is so fast that some practical utility is deprived of the gritting operation, while the construction of the means for this purpose to achieve this rapid closure can be made very cost-effectively. The means can also be processed in an attractive way in the cupboard or shop window in which it is used.
    FIG. 7A shows a trap door assembly 1 with a free-running side of the hatch with a shaft 6 supported by bearing assembly 50 and a braked side of the hatch with a shaft 6 '. Here, different from FIG. 1, because of the motor of this embodiment, no drive possibility is included in this assembly. In the hatch, substantially around the center line of the hatch in the rolled-up state, there is a motor 76 for rolling up the hatch. By using such a motor, rolling up the hatch is possible for regular closing and rolling up possible after closing the hatch under the influence of the potential force.
    The embodiment according to FIG. 7 has an assembly 30 according to FIG. 3. The shaft 6 extends to the motor assembly known per se. coupled to the cover plate 36 at interface 78, a portion or side 73, which is powered by wire 72, of a tow coupling assembly 71 is arranged in hatch assembly 70. The other side 77 of the tow coupling assembly 71 is attached to the shaft 6 '. The towing couplings 74 provide freedom of rotation between these parts 73, resp. 77 while maintaining a power connection for supplying power to the motor through power wire 12 '. The tubular motor i provides a rotation of the hatch relative to the axis in a manner known per se.
    If the closure of the hatch is initiated by means of the potential force, the brake is released and thus the shaft 6 'as a whole and the shaft rotates with the motor side 77 of the tow coupling and the entire hatch, the hatch being closed on the fast according to the present invention. The connection of the wire to the braking side of the towing coupling is hereby maintained so that the motor can be permanently supplied with power so that after releasing the brake, the hatch can be opened or released under engine power. coiled.
    In the foregoing, the present invention has been described with reference to a few preferred embodiments. Different aspects of different embodiments are considered to be described in combination with each other, whereby all combinations that are considered to be read by a person skilled in the art on the basis of this document are included in the understanding of the invention. These preferred embodiments are not restrictive of the scope of this document. The rights requested are defined in the appended claims. k k k k k
