Description:
A CLOSET SLIDING-DOORS SYSTEM

TECHNICAL FIELD The present invention relates to the field of sliding doors. More particularly, the present invention relates to the field of closet sliding doors.

BACKGROUND ART

The term "sliding doors system" refers herein as to two or more sliding doors opened / closed by sliding one door in parallel to the other.

Fig. la is a front view which schematically illustrates a sliding doors system in a closed state, according to the prior art. Fig. la also defines a cross-section A-A. Fig. lb is a top view which schematically illustrates the cross-section A-A of Fig. la. In order to facilitate the understanding, the projection lines are not drawn in the cross-section of Fig. lb.

It should be noted that the rails 20a and 20b are preferably made of a single profile, as illustrated in Figs. 5a, 5b, 6a and 6b. This ensures that the rails will be parallel.

Fig. 2a is a front view which schematically illustrates the sliding doors system of Fig. 1 in an open state. Fig. 2a also defines a cross-section B-B. Fig. 2b is a top view which schematically illustrates the cross-section B-B of Fig. 2a.

Fig. 3a is a top view illustrating a mechanism of sliding doors of a closet, according to the prior art.

The inner door 10a is suspended on rail 20a via a carriage 30a that rolls over the rail. The outer door 10b is suspended on rail 20b using a carriage 30b that rolls over the rail. In order to bypass the rolling mechanism of the inner door 10a, the rolling mechanism of door 10b uses a bridge 34. It should be noted that Figs. 5a, 5b 6a and 6b are perspective illustrations detailing this structure.

Fig. 3b is a top view illustrating a mechanism of sliding doors of Fig. 3a, wherein the outer door has been slid to the right end of the closet.

As illustrated, the door cannot be closed "hermetically" because of carriage 30b, and a gap 36 remains between the door 10b to the closet frame 14.

A door comprises a frame (the vertical bars thereof are marked by reference numeral 16) and two boards 18. The frame operates as a chassis. As such, the bridge 34 must be connected to the vertical bars 16 of the frame rather than to the board 18.

Fig. 3c schematically illustrates a mechanism that attempts to solve this problem, according to the prior art. A patch 38 is connected to both, the door frame (chassis) and the board 18 of door 10b. In addition, the bridge is connected to the left side of the carriage 30b. Of course this arrangement is far from being satisfactory: the weight of the door, which is about 50 to 70 Kg, doesn't concentrate only on the chassis, but also on the board, which may damage the board over time. In addition, the weight on one wheel of the carriage is higher than the weight on the other wheel of the carriage.

Fig. 3d schematically illustrates another mechanism that attempts to solve this problem, according to the prior art. According to this solution, the frame 14 is designed such that it hides the gap.

All the solutions of the prior art have not provided a satisfactory solution to the problem of connecting the carriages of a sliding door to the vertical bars 16 of the sliding door.

It is an object of the present invention to provide a solution to the above-mentioned and other problems of the prior art. Other objects and advantages of the invention will become apparent as the description proceeds. SUMMARY OF THE INVENTION

DESCRIPTION OF EMBODIMENTS

The present invention will be understood from the following detailed description of preferred embodiments ("best mode"), which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail. Fig. 4a is a top view illustrating a mechanism of sliding doors of a closet, according to one embodiment of the invention.

The solution is based on constructing the bridge 34 to be inclined (i.e., not perpendicular) to the rails, thereby allowing each of the carriages 30b to be disposed within the borders of the sliding door 10b thereby allowing closing the door "hermetically". This solution places the load of the door to lean on the vertical bar 16 of the door frame. As mentioned, the weight of the door may be tens of kilograms, and as such the door must be designed such that the majority of the load leans on the massive vertical bars 16 rather than on the boards of the door.

Fig. 4b is a top view illustrating a mechanism of sliding doors of a closet, according to another embodiment of the invention. The difference between Figs. 4a and 4b is that in Fig. 4b the door hides the closet's frame 14, while in Fig. 4a the closet's frame 14 is seen. Nevertheless, the provided solution which uses an inclined bridge 34 solves the problem in this case as well. The prior art solutions described herein cannot solve the problem in the case wherein the door boards hide the closet's frame.

Fig. 5a pictorially illustrates the carriage 30a rolling on rail 20a, according to one embodiment of the invention.

The carriage 30a is connected to a vertical profile 40a, which also may be the vertical bars 16 of the frame of the door (marked herein as 10a).

It should be noted that the rails 20a and 20b are a part of the same profile.

Fig. 5b pictorially illustrates the carriage 30b rolling on rail 20b, according to one embodiment of the invention.

The carriage 30b is connected to a vertical profile 40b via a bridge 34. The vertical profile 40b may also be the vertical bars 16 of frame of the door (marked herein as 10b).

Connector 42 connects the carriage 30b to the bridge 34. According to one embodiment of the invention, the connector 42 is a bolt for fixing the carriage to the bridge. According to another embodiment of the invention, the connector 42 is a vertical axle. According to yet another embodiment of the invention, the connector 42 is a horizontal pivotal connector. Thus, the connection of the carriage 34 to the bridge 42 may be fixed or adjustable / pivotal. When the connection is pivotal it may be by a vertical pivot, a horizontal pivot, and even both, vertical and horizontal.

Each of Figs. 6a and 6b pictorially illustrates how the structure prevents the carriages 30a and 30 from colliding with each other.

Each of the figures illustrates the structure from a different angle. As mentioned, the rails 20a and 20b are made of a single profile, thereby providing easy installation, and ensuring the rails are parallel to each other.

The reason the carriages 30a and 30b do not collide is the structure which employs a bridge 34 that passes over the carriages 30a and 30b. Since each of the carriages uses another rail, they do not collide.

It should be noted that the sliding mechanism of the inner door 10a may also use a bridge 34; however, since it is "close" to the vertical profile, it can be connected directly to the vertical profile. Fig. 7 is a top view of the mechanism illustrated in Figs. 6a and 6b.

As can be seen, the bridge 34 is inclined with regard to profile 40b.

Profile 40b is inclined at the regions to which bridge 34 is connected thereto. Nevertheless, the technician that mounts the sliding doors may adjust (via connector 42) the angle between carriage 30b and the bridge 34 such that the wheels of the carriage 30b will be parallel to rail 20b, as illustrated in the figure.

Preferably, the bridge 34 is made of a metal plate, bent by 90 degrees. However, the bridge may be formed differently, e.g., by soldering two plates.

Fig. 8a is a perspective view of a fixing assembly 50a for the inner rail 20a, according to one embodiment of the invention. Fig. 8b is a perspective view of a fixing assembly 50b for the outer rail 20b, according to one embodiment of the invention.

Fixing assembly 50a comprises an upper spring assembly 52 connected to its upper side, and a lower spring assembly 52 connected to its lower side. The upper carriage 30a is connected to the upper spring assembly 52, while the lower carriage 30a is connected to the lower spring assembly 52. Fig. 9a schematically illustrates the structure and operation of each of the fixing assemblies 50 in a suspension mechanism, according to one embodiment of the invention.

In the suspension mechanism the door (which is not seen in the figure) is suspended on the upper rail 20 via two carriages 30. It should be noted that only one side is illustrated, but as seen in Figs. 3a, 3b, 3c, 4a and 4b, each door is suspended by two carriages, one on its left side and one on its right side.

The lower spring assembly 52 pulls the lower carriage upwards, thereby forcing the lower carriage to roll on the lower rail even if the rail is slightly bent.

The spring assemblies are drawn in a cross-section form. Each of the spring assemblies 52 comprises a tube 54 connected by connection means 56 to the vertical profile 40. In the tube is disposed a spring 60 and a "piston" 62. Rod 58, which is connected to piston 62, connects the spring assembly to the vertical profile 40. The spring is shrunk and therefore it tends to expand. In Fig. 9a the load is on the upper rail. Thus, the spring assembly 52 is required only at the lower side. However, when also using a spring assembly 52 on the upper side, it diminishes the load on the upper rail. Fig. 9b schematically illustrates the structure and operation of each of the fixing assemblies 50 in a reclining mechanism, according to one embodiment of the invention.

In the reclining mechanism the door (not seen in the figure) reclines on the lower rail 20 via two carriages 30. In this case, the upper spring assembly 52 is used to push the upper carriage towards the upper rail 20, thereby forcing the upper carriage to roll on the upper rail even if the rail is slightly bent.

In Fig. 9a the load is on the lower rail. Thus, the spring assembly 52 is required only at the upper side. However, when also using a spring assembly 52 on the lower side, it diminishes the load on the lower rail.
