The invention relates to a presentation device for presenting a hand-held electronic media display unit.
Hand-held electronic display units (also referred to as portable electronic display devices) such as tablet computers, mobile telephones and the like are configured to display media on a screen, for instance graphic information such as still images or video footage, and/or to play sound (music, speech and the like). These display units are popular, and can be purchased in a wide variety in shops. In order to present the media display units to potential customers they are secured in presentation devices which are in turn connected fixedly to a base surface, for instance a display counter or a wall.
Presentation devices for presenting such display units usually have a dual purpose: they must prevent a customer from being able to steal the unit, but at the same time it must be possible to view the unit properly and preferably also operate it. It is moreover preferable that the customer can also hold the unit as he/she normally would during use.
Many shops secure the objects by attaching a cable to the unit, wherein this cable is in turn connected to a fixed point. Other common systems use sensors, wherein an alarm sounds as soon as the product is removed a certain distance from a station. There are also systems where the unit is enclosed in a holder.
Each of these solutions have drawbacks however. In the case of cable systems the screen and the keys of a display unit are readily accessible, but a customer can for instance not properly assess how the device lies in the hand: both the weight and the shape are changed by the attaching mechanism. The presented units are moreover often damaged by these adhering systems, whereby they can no longer be sold.
Systems with alarm can be presented easily but are less suitable for theft prevention. This is because an alarm only works if there is an employee who can intervene when the alarm goes off and can actually prevent the theft, and when it is busy the implementation of this method requires a very large number of available and alert employees.
Systems with holders often work well in respect of theft prevention. The application of holders also has advantages in respect of the manner of presenting the display unit: the units can be viewed in the holder, and buttons and/or a touchscreen can be tested properly. It is not possible for the customer to get to know how the apparatus lies in the hand, since release of the unit from the holder is often a time-consuming process requiring a screwdriver or Allen key and usually both hands, and wherein the presentation device comes apart in several pieces. A further drawback is that holders are often only suitable for one specific product and cannot be adjusted in size.
There is a need for a presentation device with which storage of the display unit in and removing the display unit from the presentation device can be performed quickly and efficiently, with less risk of damaging the display unit (particularly at the position of the screen of the display unit). There is in addition a need to be able to accomplish this without needing both hands to do so, so that the display unit can be grasped with at least one hand when the user takes hold of and removes the display unit.
According to a first aspect, a presentation device is provided for presenting a hand-held electronic media display unit (portable electronic media display device) such as a tablet computer, the presentation device comprising:
Provided according to a second aspect is a presentation device for presenting a hand-held electronic media display unit (portable electronic media display device) such as a tablet computer, the presentation device comprising:
Further features, details and advantages of the present invention will be elucidated on the basis of the following description of some embodiments thereof. Reference is made in the description to the figures.
The presentation device can for instance comprise:
In the closed state the display unit is held fixedly in the enclosing space and so cannot be separated from the presentation device (not at least without damaging the display device). The presentation device itself can be attached to a base surface (display counter, wall and so on) so that a thief cannot simply carry off the display unit. The presentation device can in addition or instead be provided with an alarm installation. The alarm installation can for instance comprise a sensor which ensures that an alarm will sound when the presentation device comes to lie too far away from the base surface, for instance because a thief carries off the presentation device with contents. When the enclosing space is opened, the frame part is displaced from a first (end) position, in which the hook remains positioned behind an edge of the display unit and the enclosing space is thus closed, to a second (end) position in which the hook is displaced parallel to the support surface (for instance outward) as well as perpendicularly of the support surface (for instance in the direction of the foot, i.e. downward when the foot is placed on top of a horizontal surface), and the associated edge of the display unit thus comes to lie completely clear. In this situation the display unit can be removed in simple manner without the chance of parts thereof, such as the screen, being damaged.
The enclosing space can take numerous forms. In many cases however the enclosing space is a substantially flat rectangular space for receiving a similarly shaped display unit therein. The frame parts, which are for instance formed by arms displaceable relative to the support and provided at the outer ends with hooks, are then arranged along each of the four sides of the enclosing space. The hooks thus surround and hold the display unit fixedly with said hooks, so that the display unit is held in the enclosing space and the greater part of the display unit, in particular the screen thereof, is still accessible by the purchaser.
In an embodiment only the one or more frame parts arranged along one side of the enclosing space are displaceable via the guide. The other frame parts can then be embodied such that they are not displaceable, at least not via the guide. In determined embodiments the other frame parts are still adjustable, particularly before a display unit has been arranged, although these other frame parts are preferably not displaceable during use, so with display unit arranged. These frame parts thus remain stationary.
In a further embodiment the presentation device comprises a locking mechanism for locking the displaceable frame parts in the first, closed state. The locking mechanism can comprise a lock or the like. The locking mechanism preferably requires a key or other identification for unlocking purposes. In a shop this can for instance be done by the shop assistant.
In a further embodiment the locking mechanism is embodied to come into operation (i.e. to lock) upon displacement of the displaceable frame parts to the first, closed state. When an operating person pushes the adjustable frame parts to the closed state a locking will automatically occur in this embodiment as soon as frame parts have reached the closed state. In yet another embodiment the presentation device comprises one or more biasing members for biasing the one or more displaceable frame parts to the second, opened state. In this embodiment the device can thus be embodied to displace the displaceable frame parts directly to the opened state under the influence of the biasing members, for instance one or more tension or compression springs, when the locking mechanism is unlocked, for instance by turning a key. Further manual intervention is thus not possible, so that the operating person has his/her hands free to grasp the display unit.
The above stated displacement of the displaceable frame parts between the two different end positions can be realized in different ways. In a determined embodiment the displaceable frame parts are displaceable between the positions via the guide in a first movement in the plane of the support surface and in a second movement transversely of the plane of the support surface. The frame parts are for instance first displaced outward when opened. As soon as the hook of a frame part has been carried beyond the edge of the display unit, the hook of the frame part can be displaced downward (without the risk of the hook touching the edge) until the enclosing space is left clear in one direction of movement. In another embodiment the frame parts are displaceable between the positions via the guide in a combined movement in the plane of the support surface and transversely of the plane of the support surface, for instance by displacing an outer end of the frame part in an arcuate path.
In embodiments one or more spring units are arranged in the support surface for the purpose of pressing the display unit under spring force against the hooks of the frame parts. An advantage hereof is that a good connection of the display unit to the hooks can be realized and the display unit will have less of a tendency to start rattling in the enclosing space. If the spring travel of the spring units is sufficiently great, it is hereby also possible to realize that the presentation device is suitable for enclosing display units of different thicknesses, this without additional steps, such as adjustment of the frame parts and the like, being necessary here.
The spring unit can comprise one or more compression springs. These can for instance be mounted on the support surface, for instance in a number of openings provided therein, wherein an outer end protrudes from the support surface. During use the outer end can press against the rear side of the display unit so that it remains pressed against the hooks of the frame parts. In other embodiments the spring unit comprises, in addition to the compression spring, a tongue mounted on the support surface and pivotable relative thereto. The compression spring presses the free outer end of the tongue against the rear side of the display unit so that it is pressed against the frame parts. In order to obtain a good distribution of forces use is often made in practice of a number of spring units, for instance six, distributed more or less uniformly over the area of the end surface, so that the display unit is also pressed uniformly against the frame parts.
In order to make the presentation device suitable for display units of differing dimensions, the position of at least one of the frame parts (preferably of all frame parts) is adjustable relative to the support surface so as to make the presentation device suitable for display units with differing dimensions. The adjustability is realized by an adjusting mechanism. The adjusting mechanism is arranged here such that in practice it is inaccessible when the presentation device is in the first, closed state and a fitting display unit is enclosed in the device. The presentation device cannot be adjusted when the display unit has been thus arranged.
In an embodiment a pivoting unit is arranged between the foot and the support surface for the purpose of pivoting the support surface and fixing thereof in a desired position. While the foot is for instance fixed onto a surface and is substantially stationary (in the case of a stationary surface), the support surface and thereby the orientation of the display unit can be changed. The pivoting unit can more particularly be embodied to rotate the support surface with enclosing space over one or more axes, whereby the angle of a display unit present in the device can be changed.
According to said second aspect, the presentation device can comprise:
The presentation device can lock an object such as a display unit by closing round it. The presentation device can further be unlocked in simple manner, whereby the unit can if necessary be quickly removed from the holder. The device is here adjustable in determined embodiments, whereby it is suitable for units with a range of dimensions. In other embodiments the other frame parts (other than the frame parts displaceable via the guide) are mounted fixedly on the support surface and adjustment of the dimensions is thus not possible. These embodiments have a simplified construction.
The figures show with broken lines 10 where the tablet or other portable media display unit is located in the closed situation. The broken lines hereby indicate the (imaginary) enclosing space 11 in which the display unit can be enclosed. The display unit usually has a substantially flat and rectangular form. The large, flat side were the (touch)screen is generally located is also referred to here as the front, and the associated direction is described as “forward” direction. As a rule a portable media display unit has a short and a long side. The short sides will be designated with left and right, the long sides with lower and upper. It will be apparent that the invention is not only applicable to such presentation devices. Presentation devices with other shapes and dimensions likewise fall within the scope of the invention.
In the closed situation the rear side of the portable media display unit extends parallel to support surface 4, wherein the rear side lies either against support surface 4 or at a short distance therefrom. A number of frame parts 50-53,55,56 are arranged on the support. These frame parts 50-53,55,56 are embodied in the shown embodiment as gripper arms. Each of the frame parts comprises a hook-shaped part or hook 40 at the free outer end (i.e. the outer end not attached to the support). A hook-shaped part comprises an upright stop part 30,30′,31-36 and a lying stop part 40,40′,41-46 so that the display unit can be enclosed not only in lateral (sideways) directions, but also in an upward direction.
The support surface and frame parts 50-53, 55 and 56 together form the above stated enclosing space 11. They can surround the display unit on all six sides. The rear side of the display unit is enclosed by support surface 4, the upper edge by stop parts 30,30′,40,40′ of frame part 50, the lower edge by stop parts 33,34,43,44 of respective frame parts 53,54, the left-hand side edge by stop parts 35,36,45,46 of the respective frame parts 55, 56 and the right-hand side edge by stop parts 31,32,41,42 of the respective frame parts 51, 52.
The frame parts are formed and positioned such that they can already hold the display unit in the enclosing space by engaging on only the peripheral edge of the display unit. The shape and position of each of the frame parts moreover make it possible that the front side of the display unit is only very partially covered and therefore remains visible and accessible to a user wishing to look at and try out the display unit. The user can for instance be an interested customer who wishes to know before purchasing how the controls of a display unit work and what the screen looks like.
The portable media display unit can have openings on the sides, upper side and lower side, for instance for connection of cords and control buttons. Since parts 30,30′,31-36 are quite thin, these openings are generally still accessible when the portable media display unit is located in the presentation device.
Provided in support surface 4 are four openings 27 in which four compression springs 21 are mounted. Pusher tongues 22 are further arranged on the support surface. Each of these tongues 22 is pivotally connected at one outer end to support surface 4. The opposite outer end is a free outer end. Compression spring 21 can press against the underside of the free outer end of a tongue 22 so that the tongue is pushed upward under spring force. Tongues 22 in turn press a display unit arranged in the enclosing space forward so that the front side of the display unit is pressed against the hook-shaped parts 40,40′,41-46 of the frame parts. The size and spring tension of these compression springs is such that the presentation device can enclose display units of differing thicknesses, provided the thickness is no greater than the distance between parts 40,40′,41-46 of the gripper arms and the support surface.
Referring to
Upper foot part 29 comprises a support element 80 with which support plate 26 is connected via an upright plate-like part 81 (
Hooks 30,30′,40,40′ are both part of a single frame part or gripper arm 50. This gripper arm 50 can be displaced in a first direction P1 in the plane of end surface 4 (
As a result of this two-fold movement, storage space 11 is only enclosed on five sides when gripper arm 50 is in the second extended situation: on the rear side still by support surface 4, on the underside by stop parts 33 and 34 of gripper arm 54, on the sides by stop parts 31,32,35 and 36 of respective gripper arms 51,52,55 and 56, and on the front side by stop parts 41-46 of gripper arms 51,52,53,55 and 56. Since enclosing space 11 is no longer enclosed on one side owing to the first displacement (direction P1) and the hook-shaped parts 30,30′,40,40′ have been pushed aside as a result of the second displacement (in the direction P2), the portable media display unit can easily be taken out on this side with less risk of damage.
A spring 91 is arranged between a mounting part 88 (
Gripper arm 50 can be locked in the retracted state via the locking mechanism. The locking mechanism comprises a lock 92 which in the locked situation (as shown in
During closing of the enclosing space the reverse process takes place, going from the position in
The dimensions of enclosing space 11 can be adapted to the size and/or shape of the display unit by adjusting the frame parts (the stationary frame parts 51-56 which are non-displaceable during use as well as the displaceable frame part (gripper arm) 50), this being shown particularly in
While the displaceable frame part 50 can also be displaced during use, so with display unit placed in enclosing space 11, the displacement of frame part 50 and the other frame parts 51-56 for the purpose of adjustment to the shape and dimensions of the display unit is not possible during use. None of the Allen screws 61,68 is accessible from outside when there is a portable media display unit in enclosing space 11, since the display unit then covers the support surface and the Allen screws 61 provided therein, and Allen screws 68 are positioned just below support surface 4. Use cannot therefore be made of the adjustability of frame parts 50-56 to release the portable media display unit from the enclosed situation.
The presentation device can for instance be manufactured wholly or largely from steel, particularly those parts which are important for fixedly holding the media display unit. Use is preferably made of hardened steel.
The present invention is not limited to the embodiments thereof described herein. The rights are defined by the following claims, within the scope of which numerous modifications can be envisaged.
