Description

  The present invention relates to a drawer part having a drawer part that can be pulled out in both the front direction and the back direction, an outer frame part that accommodates the drawer part, a drawer unit having a double-sided storage function by the drawer mechanism, a cabinet, and double-sided storage The present invention relates to furniture, a partition plate having the double-sided storage function, and the partition furniture.

The structure of the storage part that increases the storage direction and the take-out direction by making the front and rear both sides of the storage part openable, and the storage part has a different structure on the front and rear surfaces, respectively, or increased convenience, or the storage part Cabinets and cupboards have been devised. Moreover, using the furniture having such a storage part as a partition, a partition plate that enables efficient use of stored items by storing and taking out the furniture from the rooms on both sides sandwiching the partition, Partition furniture has been proposed (see Patent Document 1).
Such a double-sided storage function for cabinets and furniture is provided with a drawer mechanism that can be pulled out in both directions (see Patent Document 2), so that the convenience is further improved. 3) and double-sided storage furniture (see Patent Document 4). Furthermore, using a double-sided storage furniture having such a drawer mechanism as a partition plate, a laundry storage device that can store and take out laundry from both the wash room and the laundry room with the partition plate interposed therebetween ( Patent Document 5) has been proposed.

However, when such a bi-directional drawer mechanism is provided in the storage section, there is a problem that when the drawer is pushed in and returned to the original position which is the initial setting position, it cannot be easily returned to the initial central position. Because both sides of the drawer can be pulled out, the operation that was performed by pushing the drawer part to the stop position with a strong force in the past would cause the drawer to jump out in the opposite direction, and push it in while judging the center position of the drawer visually. The return to the center position must be adjusted by adjusting the force.
If the center position is not accurately restored, the drawer portion protrudes in one direction, and the original arrangement function of the cabinet having the double-side drawer mechanism and the double-sided storage furniture is impaired. In particular, in the case of partitioned furniture that uses double-sided storage furniture as a partition, many drawer mechanisms are often installed, and unless these drawers are accurately returned to their initial positions, the aesthetics of the partition will be greatly impaired. become.
For this reason, attention and time are required for the operation of closing the drawer portion which is the storage portion, and even the convenience of the original double-sided storage function may be impaired.
Improvements have been made to the bi-directional pull-out mechanism, and for example, a proposal for a sliding portion and a stopper has been made so that smooth pull-out can be performed with a simpler mechanism (see Patent Document 6). However, no improvement has been made with respect to operability when the drawer portion, which is a storage portion, is pushed in, and a mechanism for returning to the central position by a simple operation has not yet been presented.
JP 58-138411 A Japanese Patent Laid-Open No. 56-091711 JP-A-1-209014 JP-A-6-339413 JP 2003-038273 A JP 20091655592

An object of the present invention is to provide a double-sided drawer mechanism that can return to the center position, which is an initial setting position, only by a simple push-in operation that does not require any special adjustment, similar to a one-way drawer mechanism. .
Furthermore, an object of the present invention is to provide a cabinet with a double-sided storage function or a double-sided storage furniture that can easily return the storage unit to the center position that is the initial position by only a simple pushing operation without special position adjustment. Is to provide.
A further object of the present invention is to provide a partition plate having a double-sided storage function that can easily return the drawer portion as the storage portion to the center position as the initial setting position by a simple pushing operation without special position adjustment. Is to provide.

The inventors considered that it is necessary to adjust the position of the double-sided drawer mechanism and the double-sided drawer unit at the time of returning to the central position of the storage part by visual inspection without relying on visual inspection. The required mechanism was studied and the present invention was reached.
That is, the present invention is a drawer mechanism having a drawer part slidable in both directions from a preset center position, and an outer frame part for housing the drawer part, and the sliding resistance during sliding of the drawer part There is provided a double-sided drawer mechanism characterized by having a mechanism for guiding the return of the drawer portion to the center position by a change and a sound change.
Furthermore, the present invention provides a cabinet having the drawer mechanism.
Furthermore, the present invention provides double-sided storage furniture having a working space on both sides and having the drawer mechanism.
Furthermore, this invention provides the partition plate which has said drawer | drawing-out mechanism in at least one part of the partition plate which has a double-sided storage function.

The double-sided drawer mechanism and drawer unit of the present invention induce a return to the center position of the drawer part by sliding resistance change and sound change during sliding of the drawer part. There is no need to adjust the return to the center position, which is the initial setting position, and the drawer can be returned to the center position with a simple push-in operation, and the drawer is pushed in to return to the specified center position. Can be performed very simply.
Since the cabinet or the double-sided storage furniture of the present invention has the above-described double-sided drawer mechanism, the drawer portion is pushed in without adjusting the position only by a simple pushing operation, as in the case of a normal single-sided cabinet or storage furniture. , Can be returned to the center position. For this reason, while maintaining the double-sided storage function, the operation when pushing the drawer part into the center position and closing it is very simple and the operability is good.
Since the partition plate of the present invention has the above-described drawer mechanism, it is easy to push and close the drawer part to the center position while maintaining the double-sided storage function, and the frequency of use of the drawer part as the storage part is simple.

It is the schematic of the magnet unit for generating the sliding resistance change in the embodiment of the double-side drawer mechanism of the present invention. It is the schematic which shows the relationship between the attachment position of a magnetic metal unit and a magnet unit for generating the sliding resistance change in the embodiment of the double-sided drawer mechanism of this invention. It is the schematic which shows operation | movement of a magnetic metal unit and a magnet unit when the sliding resistance change has generate | occur | produced in the embodiment of the double-sided drawer mechanism of this invention. It is a figure which shows the embodiment of the double-sided storage furniture which has a double-sided drawer mechanism of this invention.

The double-sided drawer mechanism of the present invention is a drawer mechanism having a drawer part slidable in both directions from a preset center position, and an outer frame part for storing the drawer part, wherein the drawer part is being slid It has a mechanism for inducing the return of the drawer portion to the center position by a sliding resistance change and a sound change.
The sliding resistance change during sliding of the drawer part may be moderate or abrupt. When the sliding resistance is moderate, mainly as the drawer part approaches the center position. It can be set to gradually increase or decrease. In the case where the sliding resistance change is abrupt, if the sliding resistance change does not increase once in the middle of approaching the center position, the operation speed increases during the push-in operation, and the center position easily passes. Further, it is preferable that the sliding resistance is reduced only in the vicinity of the center position because it is easily guided to the center position during the pushing operation of the drawer portion. However, even in this case, it is preferable that the sliding resistance once increases while the drawer portion approaches the center position.

  Considering the operation speed of the drawer and the force required for the push-in operation, when the push-in operation of the drawer is started and the return to the center position is started, the sliding resistance is small and constant, and the center position It is preferable that the sliding resistance change gradually increases or suddenly increases when a certain distance is reached. Further, since the sliding resistance is high at the center position of the drawer portion, there is an advantage that the drawer portion is difficult to move from the central position once set.

  Further, since the sliding resistance is reduced during the pushing operation of the drawer portion, the person who operates the drawer portion can be guided to the center position of the drawer portion. In particular, if the sliding resistance is low only in the vicinity of the central position, the drawer is easily guided to the vicinity of the central position, and the sliding resistance is high on both sides of the central position. Even when an external force is applied to the frame or the like, the drawer portion is unlikely to come off from the center position, which is the initial setting position. However, in general, when the sliding resistance of the drawer portion decreases as the drawer portion approaches the central position, the speed of the pushing operation of the drawer portion is more likely to increase, so the drawer portion is not too large at the central position. Similarly, it is preferable that the sliding resistance is increased at least once during the approach of the drawer portion to the central position, or at least immediately after the central position, or at the time point.

  It is preferable that the sound change during sliding of the drawer portion occurs when the drawer portion reaches the center position by a pushing operation. Due to such a sound change, a person who operates the drawer part that has previously sensed that the center position of the drawer part is close due to a change in sliding resistance knows the exact position of the drawer part and stops the pushing operation. The drawer portion can be set more accurately to the center position. Furthermore, since the completion of setting to the center position of the drawer portion can be confirmed by a sound change, a person who operates the drawer portion who cannot be sure of the correct return to the center position only by changing the sliding resistance of the drawer portion will again determine the position of the drawer portion. There is no need to visually check.

Changes in the sliding resistance of the drawer can be performed by various mechanisms and methods. The sliding of the drawer portion is performed by fitting the sliding portions respectively installed on the drawer portion and the outer frame portion. Therefore, the sliding part itself may be provided with a function for causing a sliding resistance change, but the sliding resistance due to the fitting of these sliding parts is basically set to be small, and the drawer part can be moved with a small force. It is preferable to maintain a stable state and add a configuration different from the sliding portion to change the resistance during sliding.
As a method of changing the sliding resistance, it is performed by attaching members that can contact each other in accordance with the approach to the center position of the drawer portion and that can generate the sliding resistance at positions where the drawer portion and the outer frame portion face each other. be able to.
However, considering the wear of the member due to friction and changes over time in the sliding resistance, it is preferable to generate the sliding resistance during sliding of the drawer portion by the attractive force between the magnetic metal and the magnet. Is preferably generated by a change in adsorption force. Either one of the magnetic metal and the magnet is fixed to the drawer part of the double-sided drawer mechanism, and the other is fixed to the outer frame part of the double-sided drawer mechanism. It can be installed and repeated.
By using the magnetic attractive force acting between the magnetic metal and the magnet, sliding resistance can be generated in a non-contact manner. Moreover, by setting the distance between the corresponding magnetic metal and the magnet to be the minimum at the center position of the drawer section, the center position of the drawer section is reduced so that the sliding resistance is reduced as the center position is approached. In addition, the drawer can be held and fixed stably at the position. Or it is more preferable that the contact sound is generated as a sound change by setting the magnetic metal and the magnet so that they come into contact with each other. A plurality of magnetic metals and magnets that generate magnetic attractive force can be combined.

The generation of the sound change during sliding of the drawer portion may be performed only by a mechanical mechanism such as contact or striking of the sound source, or may be generated by a generation source accompanied by a power source such as a buzzer or a bell. In addition, it is preferable that the sound change during sliding is a signal that allows the operator operating the drawer to accurately detect that the drawer has returned to the center position. It is preferable that the sound change be generated in a short time when the setting of the drawer portion is completed, and it is more preferable that the sound be generated only in the short time.
Such a sound change mechanism can be electrically configured from a position detector that detects that the drawer has returned to the center position, and a sounding body that generates a sound change that becomes a signal sound. It is preferable to use only a mechanical mechanism because the structure is simple, there are few failures, and no dedicated power source is required.
As a method of generating such a sound change consisting only of a mechanical mechanism, for example, it may be generated by friction at the time of drawer sliding of a diaphragm installed in the drawer part or the outer frame part. However, the contact sound between the magnetic metal piece and the magnet piece approached by the magnetic attraction force is preferable in terms of the loudness, the sound generation point can be limited to a very narrow place, the simplicity of the structure, and the durability.
In particular, the magnetic metal and the magnet used when generating the sliding change are generated by the sound change caused by the contact sound when the magnetic metal and the magnet are brought into close contact with the central position of the drawer portion. It is preferable that a change in sliding resistance can be generated at the same time.

When the drawer part returns to the center position, when the magnetic metal and the magnet installed on either the drawer part or the outer frame part come into contact with each other, the drawer part needs to be attracted to the outer frame, The drawer part needs to move in a direction perpendicular to the sliding direction.
For this reason, in order to enable this, a combination of magnetic metal and magnet that generates a strong attracting force, or a small clearance between the drawer part and the outer frame part is required. It is necessary to properly adjust the design of the drawer part and outer frame including
On the other hand, when at least one of the magnetic metal or the magnet has a movable part, and the movable part moves by the attraction force and generates a contact between the magnetic metal and the magnet, the magnetism that even generates an attraction force sufficient to move the movable part. If a metal and a magnet can be used, it is not necessary to adjust the clearance between the drawer portion and the outer frame.

In order to be able to move by such magnetic attraction force, at least one of the magnetic metal or the magnet fixed to either the drawer part or the outer frame part needs to have a movable part. Yes, it is necessary that the moving parts of the magnetic metal or magnet move and be attracted to and in contact with each other. For this purpose, for example, one of the spherical magnetic metal and the magnet is attached to the drawer portion and the other is attached to the outer frame portion so that the spherical magnetic metal partly held by the magnet is in contact with the magnet when protruding. It can be carried out.
Alternatively, at least one of the magnetic metal or the magnet has a small piece portion that is held so as to be movable while rotating around a preset rotation axis, and the magnetic metal or the small piece of the magnet is moved by rotation by the magnetic attraction force. It is preferable to make the structure adsorbed to each other because the structure is simple, the degree of design freedom is high, and the generated contact noise is large. When the magnetic metal or magnet is a small rectangular piece, the rotary shaft may be fixed with one side as a rotary shaft and the other side rotated around the rotary shaft, or around a preset rotary axis. Alternatively, the magnetic metal or the entire magnet may rotate and move.

A magnetic metal and a magnet for generating a sliding resistance change by a magnetic attraction force during sliding of the drawer part are opposed to each other when the drawer part and the outer frame part are at the initial set position with an adhesive or the like. Although it is possible to fix it at a position, it is preferable to have an attachment fixing part having a through hole so that it can be fixed with a screw or the like. The material of these mounting and fixing portions is preferably made of a non-magnetic metal or plastic that does not affect the attractive force between the magnetic metal and the magnet and has high strength. Furthermore, you may have the holding | maintenance material for fixing these attachment fixing | fixed parts and a magnetic metal or a magnet, or hold | maintaining so that it can move.
Magnetic metals and magnets for generating these sliding resistance changes by magnetic attraction force are attached to the opposing positions of the drawer and outer frame as a magnetic metal unit and magnet unit combined with these mounting and fixing parts. Thus, a sliding change at the time of drawer sliding by the magnetic attraction force and a sound change when they are attracted are generated to guide the drawer part to the center position.
At least one of the magnetic metal and the magnet preferably has an attachment fixing portion having a through hole for attachment, and a holding material fixed to the attachment fixing portion holds the magnetic metal or the magnet in a movable state. . For example, a magnetic metal unit or a magnet unit that is a small piece that is rotatably fixed by a holding material around a rotation shaft fixed to the attachment fixing portion can be configured.

The basic structure of the double-sided drawer mechanism of the present invention is as shown in FIG. The drawer portion 1 that can be pulled out in both directions is engaged with the sliding portion 4 formed in the outer frame portion 2 that accommodates the drawer portion via the sliding portion 3 that is fixed to the drawer portion, and slides in both directions. Held possible.
The drawer part that can be pulled out in both directions in the double-sided drawer mechanism of the present invention, and the outer frame part that houses the drawer part can use the structure, material, and mechanism used in the conventional double-sided drawer mechanism. it can.

  The drawer part that can be pulled out in both directions has a front plate, a back plate, a bottom plate, and two side plates with support rails and sliding grooves for sliding when pulled out, and the upper part is open. It can be formed into a box. Alternatively, only the bottom plate is thickened to form support rails and sliding grooves on the side surfaces, and the drawer mechanism of the present invention can be applied. In order to provide a mechanism for imparting a sliding resistance change during sliding sliding, it is preferable that the original sliding resistance when the mechanism is not provided is small and that it is easy to impart a sliding resistance change. Has a support rail on the outside of both side plates, and the support rail is slidably fitted to the U-shaped outer rail fixed to the corresponding position of the outer frame portion. In contrast, a plurality of trochanters can be rotatably attached to the inner rail.

  The outer frame portion in the drawer mechanism of the present invention has a top plate, a bottom plate, and two side plates, and is configured so that the drawer portion can be pulled out in both the front direction and the back direction, and the inner side of the two side plates. Thus, a cross member corresponding to the sliding mechanism formed on the outside of the side surface of the drawer part and a U-shaped outer rail for sliding are formed in the part facing the sliding position of the drawer part.

Specific embodiments of the drawer mechanism of the present invention will be described below in detail with reference to the drawings. In one embodiment of the present invention, the magnetic attractive force between the magnetic metal and the magnet is applied between the magnetic metal having at least one movable part and the magnet to change the sliding resistance during sliding of the drawer portion. Is generated. FIG. 2 shows a magnetic metal unit 5 used in one embodiment of the present invention. The magnetic metal unit 5 includes a mounting fixing portion 7 having a mounting through-hole 6, a magnetic metal piece 8 and a magnetic metal holding piece 9 as a holding material, and one side of the magnetic metal holding piece 9 is used for the mounting. A fixed pin 10 that is a rotating shaft installed in the fixed portion 7 is fixed, and as shown in FIG. 3, the magnetic metal piece 8 and the magnetic metal holding piece 9 can rotate around the fixed pin 10 that is the rotating shaft. ing.
The magnetic metal or magnet having such a movable part is normally held in the orientation shown in FIG. 3 with the rotating shaft horizontal and the rotating shaft at the top. Therefore, when the magnetic attraction force does not work, the magnetic metal holding piece 9 and the magnetic metal piece 8 are stationary in the vertical direction by their own weight through the rotating shaft.

On the other hand, in one embodiment of the present invention, the magnet unit 11 that exerts a magnetic attraction force between the magnetic metal unit 5 and the magnetic metal piece 8 is in the shape of a small piece and is a neodymium magnet that forms the adsorption portion 12. A magnet 13 and a non-magnet having a window-like opening for the magnet to form the attracting portion 12, holding the magnet 13 with the magnet surface exposed at the attracting portion 12, and having a mounting through-hole 14 It is formed from the attachment fixing | fixed part which is a metal. By forming the opening of the attracting portion with a nonmagnetic metal, the magnetic lines of force concentrate in a narrow range, and a strong magnetic attracting force can be exerted in a narrow range where the magnetic metal of the magnetic metal unit and the attracting portion are close to each other.
A magnet having such a shape can increase the magnetic attraction force in a narrow range of the relative position between the magnetic metal and the magnet by forming the width of the magnet portion substantially the same as the width of the movable portion of the magnetic metal. The return to the center position can be performed more accurately.

  As shown in FIG. 5, the magnetic metal unit or the magnet unit having the through-holes for mounting are pulled out at positions opposite to each other outside the side plate of the drawer portion or inside the side plate of the outer frame portion in the drawer mechanism of the present invention. When the parts are initially in the set position, they can be fixed and used so that they are closest. The magnetic metal unit and the magnet unit may be installed only on one side of the drawer portion or may be installed on both.

  FIG. 6 shows the contact state between the magnetic metal and the magnet when the drawer portion to which either one of the magnetic metal unit 5 and the magnet unit 11 is attached reaches the center position. The magnetic metal piece 8 of the magnetic metal unit 5 is rotated around a fixed pin that is a rotating shaft by a magnetic attractive force between the magnetic metal piece 8 and the attracting portion 12 of the magnet 13 of the magnet unit 11, and one end of the magnetic metal is attracted to the magnet unit. It contacts the part 12 and generates a loud contact sound at this time. On the other hand, the width of the attracting portion 12 is substantially the same as the width of the magnetic metal piece 12 that is the movable portion, and strong magnetic field lines are concentrated in a narrow region. A large magnetic resistance is generated when a large change in sliding resistance occurs in the periphery and the positions of the attracting portion 12 and the magnetic metal piece in the sliding direction coincide with each other. For this reason, when the drawer portion is guided to the center position, which is the initial setting position, and the one end drawer portion is set to the center position, there is little misalignment due to external force, and the drawer portion is stably set to the initial position. Can be held.

  The double-sided drawer mechanism of the present invention is applied to a drawer part capable of double-sided drawer as each storage part in a cabinet and a cabinet storage part main body as an outer frame part, and the sliding resistance change during sliding is applied. It can be set as the cabinet which has the double-sided drawer mechanism which guides the reset to the center position set beforehand by the sound change.

Furthermore, the double-sided drawer mechanism of the present invention is a double-sided drawer unit having the function of the drawer mechanism, and is a drawer part capable of double-sided drawer as each storage part in the double-sided storage furniture and a double-sided storage furniture as the outer frame part. The double-sided storage furniture can be applied to the storage unit main body to induce a return to a preset center position by a sliding resistance change and a sound change during sliding. The external appearance of the front side of an example of the double-sided storage furniture is shown in FIG. By making it possible to store both sides, the front and back appearances can basically be made the same.
These cabinets and double-sided storage furniture to which the double-sided drawer mechanism of the present invention is applied realizes easy return to the center position by a simple pushing operation of the drawer part, which could not be achieved by the conventional double-sided drawer mechanism. The operation of closing the part is not complicated, and after closing the drawer part, the initial set position is accurately aligned, so that the appearance is not impaired. For this reason, for example, even if tableware is stored and used as a double-sided storage furniture with both the kitchen and dining room as work spaces, stored items can be used from both work spaces, and the drawer part can be easily moved to the initial setting position. Since it is restored, the drawer stop position does not fall apart, and even when the double-sided storage furniture is viewed from the dining side, the aesthetic appearance is not impaired and the harmony of the whole dining is not impaired.

  Furthermore, the double-sided drawer mechanism of the present invention can be applied to a part having at least a part of a partition wall having a double-sided storage function and having a storage part that can be pulled out on both sides. By using such a partition wall, for example, as a partition wall between a washroom and a laundry room, by applying a drawer portion having a double-sided storage function to which the double-sided drawer mechanism of the present invention is applied, for example, the washroom is made into a laundry room. The clothes that have been washed can be stored and taken out from the washroom, and the clothes that need to be washed can be delivered to the laundry room. Since the drawer position is returned to the intermediate position by a simple push-in operation in spite of frequent pull-out and push-in operations, the aesthetic appearance of the partition wall is not impaired and extremely convenient.

  The double-sided drawer mechanism of the present invention, the cabinet equipped with the drawer mechanism, the double-sided storage furniture, and the partition plate can set the drawer part to the center position which is the initial setting position by a simple pushing operation, and the convenience of double-sided storage Is further enhanced.
