Description

Cabinet door {CABINET DOORS}

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

Recently, there has been a call for the government to restrict the display of certain products in a retail environment while allowing them to sell them to consumers. For example, certain governments place restrictions on the ability of retailers to display tobacco products.

The introduction of these restrictions creates difficulties for retailers.

First, many people have invested heavily in display cabinets to display these products, and are faced with the potential need to replace such display cabinets to meet the demands of these limitations.

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

Furthermore, without a suitable cabinet structure with space to store these products, it is difficult for the retailer to ensure that the display of the product is prevented at all times except when the product is obtained for sale to the consumer, and the risk of violating restrictions on the retailer. Leaves.

EP 2 565 356 A1 has a skeleton for fixing two sliding doors and an arrangement of teeth and valleys, optionally connecting the two doors so that when the first of the doors is opened, the second of the doors is pulled open and the second of the doors is opened. And a connecting means that, when opened, disengages the connecting means so that the first remains closed.

This solution proves particularly satisfactory in terms of the function of the door unit and the efficiency of opening/closing the door so that the product is hidden from view. However, the tooth and trough connection mechanism can undergo significant wear and tear and can become noisy during use. In addition, this connection mechanism is accessible from the outside of the door unit and can be easily replaced. The effect on the aesthetics given to the door unit need not be mentioned.

The present invention seeks to address the above and other problems.

According to the present invention a door unit for an exhibition cabinet is provided, and the door unit includes:

A skeleton for fixing at least the upper and lower sliding doors; And two doors are selectively connected so that when the first of the doors is opened, the connecting means is bound to the second of the doors and pulled to open it, and when the second of the doors is opened, the connecting means is detached and the first door is closed. The means of connection to remain as. Preferably the connecting means is hidden from the user at any position on the door.

The doors may be located adjacent to each other and/or may be arranged to slide in the same direction. The connecting means, contrary to the tooth and trough or gun barrel arrangement known from the prior art, are arranged against the sliding door and the skeleton of the door so that the two doors are bound together when the first door is opened, and the other when the second door is opened. It is detached and arranged so that it is always hidden from the person actuating the door of the skeleton. This is particularly advantageous in that the visible area of the door unit of the present invention is free from a pattern and always visible mechanism to provide a clean and clean design. This can also reduce the likelihood that something gets trapped in the means of connection.

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

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

Advantageously, the connecting means are respectively installed at the rear or fixed to the longitudinal section of the upper and lower sliding doors so that they are hidden from the user when the door units are installed in the cabinet. Preferably the connecting means can be hidden from the user at any position on the door.

In a more preferred embodiment, the connecting means comprises an adjacent member, and the adjacent members are joined adjacent to each other when the first of the sliding doors is opened so as to open the second of the sliding doors simultaneously, and the first of the sliding doors is closed. It is configured to be removed when the second of the sliding doors is opened so as to remain.

In this preferred embodiment, the adjoining member is attached to the first of the sliding doors and is integral with at least a first sliding unit that is slidably installed on the skeleton and a second sliding unit that is attached to the second of the sliding doors and is slidably installed on the skeleton. I can.

Further, preferably the sliding unit may comprise rollers or wheels installed on a common rail in the frame located between the upper and lower doors. The rail preferably has a substantially C-shaped cross section.

Further, preferably the rollers or wheels are installed on the same track of the rail, the track preferably having a substantially U-shaped cross section. Advantageously, the rail can be provided in the cross member of the frame located between the two sliding doors and in 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 member for absorbing impact and noise on the binding. Such damping and/or absorbing means may preferably comprise rubber or silicone gaskets, pieces or sleeves or other soft plastic elements that are capable of absorbing impact and are inexpensive to manufacture and are easy to replace when worn.

The frame of the door unit of the present invention may be arranged so that it can be newly mounted in a reference exhibition cabinet.

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

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

The units and/or skeletons and/or doors can be arranged such that advertising or exhibition oriented material can be easily fixed there.

With the unit of the present invention, it is possible for a retailer to selectively display an alternative item to the user on an automatic basis while obtaining the product requested by the consumer. In addition, retailers can retrofit the unit of the present invention to meet the display restriction needs without the need to install a completely new cabinet.

Also, retailers are only displayed when the product is approached through the automatic closing of the door, so that any door is accidentally left open so that the product is not placed on continuous display.

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

Embodiments of the invention will be disclosed with the following reference numerals in the accompanying drawings:

2a and 2b show the open position of a vertical pair of upper and lower doors of the unit of FIG. 1;
3A and 3B show rear views of the door unit in the open position shown in FIGS. 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 the door closed position;
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;
7 and 8 respectively show front and rear views of the door of FIG. 1 with only one of the doors in the open position and the other door being closed.

Referring to Figure 1, the door unit 1 according to the present invention is a skeleton 2 formed from the top, middle and bottom cross rail members 3, 4, 5 and vertical side members 6, 7 connected to the ends of the cross rail members 3, 4, 5 Includes. The door unit may be delivered as a unit or may alternatively be attached to a cabinet skeleton that may be configured to be newly mounted around an existing exhibition cabinet that has already been installed.

The two upper doors 8 and 9 are slidably installed on the upper and intermediate transverse rail members 3 and 4, and the two lower doors 10 and 11 are slidably installed on the intermediate and bottom transverse rail members 4 and 5. Preferably the upper and lower doors may be made of opaque materials such as, for example, unpatterned or reduced wood or extruded or shaped rigid plastic materials such as polyvinylchloride, PEEK, polyurethane or the like.

According to the present invention, the upper and lower doors 8, 9, 10, and 11 are installed in pairs consisting of one upper and one lower door on the cross rail members 3, 4 and 5. Each pair of doors 9, 10; 9 and 11 are offset from each other and slide in respective vertical sliding planes P1 and P2. Thus, as shown in Figs. 1 and 2A, the first pair made of upper and lower doors 9 and 11 is slidably installed on the first or front sliding plane P1, and the upper and lower doors 8 as shown in Figs. 2B and 3A. The second pair, made of 10, is slidably installed on the second or rear sliding plane P2. As can be easily understood from Figs. 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 the middle and bottom cross rail members 4, 5 in their respective sliding planes P1, P2. This can preferably be achieved by means of transverse rail elements 3, 4 and 5 each comprising two sliding tracks. The first or front track 3a, 4a, 5a is, for example, a classic C-shaped cross section for supporting doors 9, 11 in the front sliding plane P1, and the second or rear track 3b, 4b, 5b is for example a rear sliding It can be a classic C-shaped cross section symmetrical with the front track to support doors 8 and 10 in plane P2.

The sliding doors 8, 9, 10, 11 slide in the cross rail members 3, 4, 5 between the closed position as shown in Fig. 1 and the open position shown in Figs. 2A and 2B. When in the closed position and when the door unit 1 is mounted on the cabinet, the contents of the cabinet attached to the skeleton 2 are not visible to the user.

As shown in Figs. 3 to 5, in a preferred embodiment of the door unit 1 of the present invention, the sliding doors 8, 9, 10 and 11 are respectively two upper and two lower sliding units 12 by means of cross rail members 3 and 4 , It is installed to be able to slide on 5. Each of the slide members 12 may be identical as shown in the figure, and by any suitable means (screws, nails, etc.) the front or rear rail tracks 3a, 4a, 5a of the transverse rail members 3, 4, 5; It may comprise a mounting plate or body 121 fixed to the rear surface of the door that supports rollers/wheels 122, which are bound to one of 3b, 4b, 5b or preferably stored therein. As can be seen more clearly in FIGS. 5 and 8 showing the rear view of door unit 1 in the closed position of all sliding doors 8, 9, 10, 11, the sliding unit connected to the sliding doors 9, 11 within the same front sliding plane 12 has its wheels 122 hidden in the front tracks 3a, 4a, 5a of the cross rail members 3, 4, 5, and the sliding unit 12 connected to the sliding doors 9, 10 in the same front sliding plane P2 is the cross rail member It has its wheels 122 hidden in the rear tracks 3b, 4b and 5b of 3, 4 and 5.

It is to be understood that the slide unit 12 may differ from the form and/or structure shown or described in the drawings. For example, wheels or rollers 122 may be fixed to slide units 12 that fit into a housing made within the cross section of each door to improve the simplicity of the system and prevent the slide units from contacting items stored in the cabinet when the door slides. I can.

According to the present invention, as shown in detail in FIGS. 4 and 6, the door unit 1 includes connection means 13 for selectively connecting the upper and lower doors 8, 10 and 9, 11 mated in the rear and front sliding planes P1 and P2, respectively. Include more. In the preferred embodiment shown in the figure, the connecting means 13 is integral with and part of at least one of the sliding units 12 of each door and of the sliding unit 12 (or one side of the sliding unit which can contact the other sliding unit when the door is sliding). And an adjacent member or stopper 123 extending forward of the wheel 122. In order to absorb the impact and noise on the fastening of the connecting means of the upper and lower door pairs sliding on the same plane P1, P2, the adjacent members are preferably damped with rubber or silicone gaskets, pieces or sleeves or other soft plastic elements. It has means 14.

In at least one sliding unit 12 and intermediate cross rail member 4 of each of the upper doors 8 and 9 sliding in the intermediate cross rail member 4 to ensure the selective engagement between the upper and lower doors sliding in the same plane P1, P2. At least one sliding unit 12 of each of the sliding lower doors 10 and 11 is installed on a corresponding door so that the joining member 123 contacts and engages with each other in the closed position of the door (see Figs. 3A and 5).

Because of the connection means 13 of the invention, and in particular as can be seen in FIGS. 3A to 8, the first of the doors, for example, as can be seen in the drawings, when the lower doors 10 and 11 are opened, the connection means 13 is the second of the doors. Things, for example upper doors 8 and 9 to pull open and engage with it. Conversely, when one of the upper doors 8 and 9 is opened (see Figs. 7 and 8), the connecting means 13 is detached and the corresponding pair of lower doors 10 and 11 remain closed. Advantageously according to the invention the connecting means 13 is hidden from the user at any position of doors 8, 9, 10, 11 in order to prevent its alteration and provide a patternless front surface for doors 8, 9, 10, 11. Is configured to

It should be noted that the connecting means between the two doors is configured in an alternative arrangement to that shown in the drawings so that the lower door can always be opened even when the upper door is opened.

Furthermore, means may be provided on one or more sliding doors to ensure that the doors close automatically when not approached. An exemplary arrangement capable of achieving this of FIGS. 3A to 8 together with the designation is a rope tensioned across the pulley 16 of the edge of the door 8, whose free end is connected to the closet edge of the second upper door 9 in the closed position of the door. Or it could be a trail mechanism fixed to the back of door 8 with cables. This configuration ensures that when either of the upper doors 8 and 9 is opened, it pulls the rope connected to the trail 15 which automatically rewinds the rope when the door opened by the user is freely released or closed. A similar arrangement can be used to automatically close the lower doors 10 and 11 of door unit 1 again.

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

As will be appreciated from the above description, the present invention provides a set of cabinet doors that allow retailers to simply and efficiently meet changing legislation for the display of specific products. It also allows retailers to locate products in the most appropriate and sustainable manner for gantry and storage management, and allows retailers to monitor cabinet contents.
