Description

CABINET DOORS {CABINET DOORS}

The present invention relates to cabinet doors. In particular, it relates to cabinet doors for use in retail display environments.

Recently there was a urge to allow the government to limit the display of certain products in the retail environment while still allowing them to sell to consumers. For example, certain governments have limited ability to display tobacco products from retailers.

The introduction of these restrictions creates difficulties for retailers.

First, many people have invested heavily in display cabinets to exhibit these products, and face the potential need to replace such display cabinets to meet the demands of these restrictions.

In addition, restrictions on exhibits can hinder retailers from making consumers aware of new or improved products.

Further, without a suitable cabinet structure with a space for storing these products, it is difficult to ensure that retailers are always prevented from exhibiting the product, except when the product is acquired to be sold to consumers, .

EP 2 565 356 A1 has a skeleton for securing two sliding doors and an arrangement of teeth and valleys to selectively connect two doors so that when the first one of the doors is opened the second one of the doors is pulled open and the second one And a connecting means for releasing the connecting means when opened so that the first remains in the closed state.

This solution proves particularly satisfactory in terms of the functionality of the door unit and the efficiency of opening / closing the door so that the product is hidden from view. However, the tooth-valley connection mechanism can experience significant wear and tear during use. In addition, this connection mechanism is accessible from outside the door unit and can be easily replaced. It is not necessary to mention the effect on the aesthetic feature given to the door unit.

The present invention is intended to address these and other problems.

According to the present invention there is provided a door unit for a display cabinet, the door unit comprising:

A skeleton for fixing at least upper and lower sliding doors; And when the first one of the doors is opened, the connecting means is engaged with the second one of the doors so as to open it, and when the second one of the doors is opened, the connecting means is detached and the first door is closed As a means of connection. Preferably the connecting means is hidden from the user at any position of the door.

The doors may be positioned adjacent to each other and / or arranged to slide in the same direction. The connecting means are arranged relative to the sliding door and the skeleton of the door so as to couple the two doors to each other when the first door is opened, as opposed to the teeth and valleys or gun arrangements known from the prior art, Disengaged and always hidden from the person operating the skeletal door. This has the advantage, in particular, that the visible area of the door unit of the present invention is free from the patternless and always visible mechanism, thus providing a clean and clean design. This can also reduce the likelihood of something being trapped in the connection means.

In a preferred embodiment of the invention, at least the upper and lower sliding doors slide on the framework in the same vertical plane.

In this preferred embodiment, the connecting means can also be tied to the same vertical plane, such as the sliding plane of the door. This has the advantage that it is possible to provide a very small door unit while maintaining the functionality that does not disturb the storage space in the cabinet with the door unit of the present invention.

Advantageously, the connecting means are each mounted on the rear side or in the longitudinal section of the upper and lower sliding doors so that they are hidden from the user when the door unit is installed in the cabinet. Preferably the connecting means can be hidden from the user at any position of the door.

In a more preferred embodiment, the connecting means comprises an adjacent member, the adjacent member being adjacent to each other when the first one of the sliding doors is opened so as to simultaneously open the second one of the sliding doors, and the first one of the sliding doors is closed And is detached when the second one of the sliding doors is opened so as to leave it.

In this preferred embodiment, the adjacent member is at least a first sliding unit attached to the first one of the sliding doors and slidably mounted on the frame, and a second sliding unit attached to the second one of the sliding doors and slidably mounted on the frame .

Also preferably, the sliding unit may comprise rollers or wheels mounted on a common rail in the framework positioned between the upper and lower doors. The rails preferably have a substantially C-shaped cross-section.

Also preferably, the roller or wheel is mounted on the same line of the rail, and the line preferably has a substantially U-shaped cross-section. Advantageously, the rails can be provided in a transverse member of the framework located between the two sliding doors and within the same vertical sliding plane, such as two sliding doors.

In a more preferred embodiment of the door unit of the present invention, the adjacent member of the connecting means comprises a damping element for absorbing impact and noise on the binding. These damping and / or absorbing means may preferably comprise rubber or silicone gaskets, pieces or sleeves or other soft plastic elements which are capable of absorbing impacts and which are inexpensive to manufacture and easy to replace when worn.

The skeleton of the door unit of the present invention can be arranged so as to be newly installed in the reference exhibition cabinet.

The unit may further be provided with one or more door closing mechanisms to allow one or more doors to be automatically closed. The closure mechanism may include one or more hydraulic closure mechanisms, a deflected weight closure mechanism, weighted pully, a spring and a ratchet, or a coil spring drive mechanism.

Preferably, the door may be formed of an opaque material.

The unit and / or skeleton and / or door may be arranged so that the advertisement or exhibition-oriented material can be easily fixed thereon.

With the unit of the present invention it is possible for the retailer to selectively display alternative items to the user on an automatic basis while obtaining the product required by the consumer. In addition, the retailer can tailor the display limit requirement without having to install a completely new cabinet with a freshly installed unit of the present invention.

Also, the retailer will only be displayed when the product is approached through the automatic closing of the door, leaving any door open accidentally, preventing the product from being placed on an ongoing display.

According to the present invention there is provided an exhibition cabinet comprising a housing comprising one or more shelves and further comprising any one of the units stored within the housing.

BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the invention will now be described with reference to the accompanying drawings in which:

1 is a front view of a unit according to the invention comprising two upper and two lower sliding doors;
Figures 2a and 2b show the open position of the vertical pair of upper and lower doors of the unit of Figure 1;
Figures 3a and 3b show a rear view of the door unit in the open position shown in Figures 2a and 2b, respectively;
Figure 4 shows an enlarged view of the connection mechanism between the upper and lower doors of the unit in the open position of Figure 3;
Figure 5 shows a rear view of the unit of Figure 1 in a closed position of the door;
Figure 6 shows an enlarged view of the connection mechanism between the upper and lower doors of the unit in the closed position of Figure 1;
Figures 7 and 8 show front and rear views, respectively, of the door of Figure 1, where only one of the doors is in the open position and the other door is closed.

1, a door unit 1 according to the present invention comprises a frame 2 formed from upper, middle and bottom transverse rail members 3, 4, 5 and vertical side members 6, 7 connected to the ends of transverse rail members 3, . The door unit may be attached to a cabinet framework that may be shipped as a unit or alternatively may be configured to be retrofitted around an existing display cabinet that is already installed.

Two upper doors 8, 9 are slidably mounted on the upper and middle transverse rail members 3, 4, and two lower doors 10, 11 are slidably mounted on the intermediate and bottom transverse rail members 4, Preferably, the upper and lower doors may be made of opaque material, such as, for example, undrawn or reduced wood or extruded or shaped hard plastic material such as polyvinyl chloride, PEEK, polyurethane or the like.

According to the invention, the upper and lower doors 8, 9, 10, 11 are installed in pairs consisting of one upper and one lower door in the transverse rail members 3, 4, Door pair 9, 10; 9, 11 are offset from each other and slip at respective vertical sliding planes p1, p2. Thus, as shown in Figs. 1 and 2a, the first pair of upper and lower doors 9, 11 are slidably mounted on the first or front sliding plane P1, and as shown in Figs. 2b and 3a, , A second pair made of 10 is slidably mounted on the second or rear sliding surface P2. As can be readily appreciated from Figures 1 and 2, the vertical sliding planes P1 and P2 are parallel and offset so that the upper sliding doors 8,9 can slide simultaneously in their respective sliding planes P1, P2 along the upper and intermediate transverse rail members have. Similarly, the lower doors 10, 11 can slide along their respective sliding planes P1, P2 along the intermediate and bottom transverse rail members 4, 5. This is preferably achieved by means of transverse rail members 3, 4, 5 each comprising two sliding lines. The first or front lines 3a, 4a, 5a are, for example, classic C-shaped cross-sections for supporting the doors 9, 11 in the front sliding plane P1 and the second or rear lines 3b, 4b, 5b are, for example, Shaped cross section symmetrical with the front line for supporting the door 8, 10 in the plane P2.

Sliding doors 8, 9, 10, 11 slide in the transverse rail members 3, 4, 5 between the closed position as shown in Fig. 1 and the open position shown in Figs. 2a and 2b. The contents of the cabinet attached to frame 2 are not visible to the user when the door unit 1 is in the closed position and when the door unit 1 is mounted in the cabinet.

3 to 5, in the preferred embodiment of the door unit 1 of the present invention, the sliding doors 8, 9, 10, 11 are each provided with two upper and two lower sliding units 12, And 5, respectively. Each of the slide members 12 may be the same as shown in the figure and may be mounted on the front or rear rail lines 3a, 4a, 5a; 5a of the transverse rail members 3, 4, 5 by any suitable means (screws, 3b, 4b, 5b, or preferably a mounting plate or body 121 secured to the rear surface of the door supporting the roller / wheel 122 stored therein. 5 and 8, which show a rear view of the door unit 1 in the closed position of all the sliding doors 8, 9, 10 and 11. As can be seen more clearly, the sliding unit 12 has its wheel 122 latched on the front lines 3a, 4a, 5a of the transverse rail members 3, 4, 5 and the sliding unit 12 connected to the doors 9, 10 sliding in the same front sliding plane P2, 3, 4, 5, and its wheels 122 lying under the rear lines 3b, 4b, 5b.

It should be appreciated that the sliding unit 12 may differ from the shape and / or structure shown or described in the figures. For example, a wheel or roller 122 may be secured to a sliding unit 12 that fits into a housing made in the cross section of each door to improve the simplicity of the system and prevent the sliding unit from contacting the article stored in the cabinet when the door slides .

4 and 6, the door unit 1 has connecting means 13 for selectively connecting the upper and lower doors 8, 10 and 9, 11 mated in the rear and front sliding planes P1, P2, respectively . In the preferred embodiment shown in the figures, the connecting means 13 is integral with and at least part of at least one of the sliding units 12 of each door, and the sliding unit 12 (or one of the sliding units which can contact the other sliding unit when the door slides) And an adjacent member or stopper 123 extending forward of the wheel 122. [ In order to absorb the impact and noise on the tangency of the connecting means of the upper and lower door pairs which do not interfere in the same plane P1, P2, the adjacent member preferably comprises rubber or silicone gaskets, pieces or sleeves or other soft plastic elements And a damping means 14.

At least one sliding unit 12 and intermediate transverse rail member 4 of each upper door 8, 9 slid in the intermediate transverse rail member 4 to ensure selective engagement between the upper and lower doors sliding in the same plane P1, P2 At least one sliding unit 12 of each sliding lower door 10, 11 is mounted on the corresponding door so that the joining member 123 is tangent to each other at the closed position of the door (see FIGS. 3A and 5).

Due to the connecting means 13 of the present invention, and particularly as seen in Figs. 3a to 8, when the first one of the doors, for example the lower doors 10, 11, is opened as shown in the figure, For example to pull the upper doors 8, 9 together to open it. Conversely, when one of the upper doors 8, 9 is opened (see Figs. 7 and 8), the connecting means 13 is detached and the corresponding pair of lower doors 10, 11 remain closed. According to the invention, advantageously, the connecting means 13 is hidden from the user at any position of the doors 8, 9, 10, 11 in order to prevent its tampering and to provide a patternless front surface for the doors 8, 9, .

It should be appreciated that the means of connection between the two doors is configured in an alternative arrangement to that shown in the drawings, such that the lower door can always be opened even when the upper door is opened.

Furthermore, the means may be provided on one or more sliding doors to ensure that the doors are closed automatically when they are not being accessed. 3a-8 with its sign is that the free end of its rope extends over the sheave 16 at the edge of the door 8, which is connected to the closet edge of the second upper door 9 at the closed position of the door, Or a trail mechanism fixed to the rear side of the door 8 together with a cable. This arrangement prevents pulling the rope connected to the trail 15, which automatically rewinds the rope when the door opened by the user is freely released or closed when either of the upper doors 8, 9 is opened. A similar arrangement can be used to automatically close the lower doors 10, 11 of the door unit 1 again.

Another example of a closing mechanism may include a rotating weight configuration that deflects the hydraulic piston or sliding door disposed by the sliding door back into the closed position in a closed position.

As will be appreciated from the above description, the present invention provides a set of cabinet doors that allow a retailer to simply and efficiently meet changing regulations for the display of a particular product. It also allows the retailer to locate the product in the most appropriate and ongoing way for gantry and storage management and allows the retailer to monitor the contents of the cabinet.
