Sliding door interlocking and positioning magnet unit

Abstract

This invention provides a sliding door interlocking and positioning magnet unit that allows multiple sliding doors to be easily interlocked and automatically adjust their positions when closed, using a non-destructive, non-electric, and non-mechanical method. [Solution] The sliding door interlocking and positioning magnet unit is configured such that a magnet unit 30, which can be attached with double-sided tape to the overlapping part of the sliding door, is installed so that the opening and closing operation of one side causes the other side to be interlocked by magnetic force. By arranging the magnets at multiple attachment points, multiple attachment points act simultaneously when the door is closed, causing the entire door to align naturally. It does not impair the aesthetics, is easy to install, and can be easily restored to its original state.

Description

Technical Field

[0001] The present invention relates to a sliding door of a building fixture, and relates to a magnet unit that interlocks multiple sliding doors by magnetic force and automatically aligns their positions when closed. It is characterized by being able to be constructed in a non-destructive and retrofitted manner.

Background Art

[0002] Conventionally, mechanical elements such as link mechanisms, rollers, and guide rails have been used for the interlocking of sliding doors, resulting in problems such as large-scale construction and high costs. Furthermore, in order to eliminate gaps and steps when closed, separate members such as stoppers are required, which pose problems in terms of appearance and workability.

Summary of the Invention

Problems to be Solved by the Invention

[0003] To provide a unit that can simultaneously achieve the interlocking of sliding doors and position correction when closed without using mechanical elements, and can balance simple construction and appearance.

Means for Solving the Problems

[0004] A unit made of a magnet or a metal plate capable of magnetic adsorption is provided at the overlapping portion of adjacent sliding doors, and is configured such that one sliding door interlocks with the other by magnetic force as the other is opened and closed. When closed, one or more adsorption points provided vertically act, and the sliding doors naturally align and stop. Also, the arrangement direction of the magnet may be slightly skewed with respect to the closing direction of the door. In this case, the adsorption force also acts in the position correction direction, making the alignment more stable.

Embodiments for Carrying Out the Invention

[0005] This unit uses a thin neodymium magnet and is configured to be installed by non-destructively attaching it with a strong adhesive double-sided tape. Construction is completed only by planar attachment without the need for tools, and it is also easy to restore to the original state.

[0006] When one sliding door is opened or closed, the adjacent sliding door moves loosely in conjunction with it due to magnetic force. When closed, the magnetic attraction points located at the top and bottom sequentially attract each other, and the entire door aligns parallel to each other. If necessary, one side can be made into a magnet and the other into a metal plate that can be magnetically attracted, making it suitable for lightweight doors and narrow gap structures.

[0007] The exposed surfaces of the magnets can be painted or covered to match the color scheme of the sliding door, thus maintaining their aesthetic appeal.

[0008] In particular, compared to the "sliding door interlocking mechanism" covered by the previously registered "Utility Model Registration No. 3252520," this invention has a new effect that also serves as a position correction function when the door is closed by applying the action of magnetism. This makes it possible to achieve both interlocking and positioning with a single configuration, and it is possible to obtain the same level of alignment with simple construction without using mechanical parts. Furthermore, this invention is novel in that, in addition to the conventional interlocking mechanism, it realizes automatic alignment when the door is closed. Configuration of the magnetic unit

[0009] The magnet unit used in this invention (see Figure 3) has the following configuration. • The external shape can be any shape, such as a rectangle or a circle, and is configured to be able to adhere without interfering with the gap between sliding doors. The magnets are made of strong magnetic materials such as neodymium, and their thickness, width, and length can be appropriately set according to the gaps and magnetic force required for installation. • The magnetic sliding door contact surface is pre-attached with strong adhesive double-sided tape (such as 3M "VHB"), allowing for tool-free installation. • The exposed surfaces are finished with a surface treatment (paint or resin cover) that matches the color tone of the sliding door, thus maintaining its aesthetic appeal. • It is also possible to optionally add marks indicating polarity (N pole / S pole) to the ends or back surface. The attraction force can be controlled by adjusting the number of units, the material of the magnet, or the surface area.

[0010] The magnets may be positioned slightly oblique to the door's closing direction; in this case, the magnetic force also acts in the position correction direction, resulting in more stable alignment. On the other hand, a sufficient alignment effect can also be obtained by arranging them in parallel.

[0011] This allows users to install the product flexibly according to the site environment (gap dimensions and material), and prevents resistance caused by excessive suction. This invention provides a versatile configuration that does not require a specific shape and performs natural attraction correction through the action of magnetism.

[0012] According to this invention, multiple sliding doors can be simultaneously linked by simply attaching double-sided tape. Furthermore, the natural alignment action of multiple suction points at the top and bottom automatically corrects any misalignment when the device is closed. This allows for a simple configuration that combines interlocking and positioning without requiring any special processing. [Brief explanation of the drawing]

[0014] Two pairs of plate-shaped neodymium magnets were placed vertically at the overlapping section of two wooden sliding doors, and a magnet or metal plate was installed on the opposite side. Interlocking occurs during opening and closing operations, and when closed, misalignment is corrected by suction, resulting in alignment.

[0015] In a three-panel sliding door configuration, we confirmed that when the middle door is operated, the doors on both sides follow in stages, and the entire system aligns and stops. [Industrial applicability]

[0016] This invention is widely applicable to sliding doors in houses, shops, accommodations, etc., and is advantageous in terms of ease of installation, design, and cost. The naturally aligned structure created by the vertical arrangement can be applied to other sliding doors and windows as well.
