Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture such as a drawer cabinet for storing files.

[0002]

2. Description of the Related Art In general, drawers such as drawer cabinets are pulled out to the front to insert and remove contents such as files. However, there are some which can open the top plate of the cabinet. There is a form to do. If the top plate is opened, the contents can be taken in and out from above, which is convenient in some cases. For example, if there is a (temporary) obstruction object in front of the cabinet, or
Since the contents are stored only in the top row, the stability of the cabinet will be worse if it is pulled out, and in the worst case it will fall over, or if the necessary documents are stored in the rear of the drawer, pull out and pull out There may be a case where the user wants to take in and out from above rather than performing the work of taking in and out.

[0003]

However, when the top plate is dropped, an impact acts on the top plate to damage the top plate or the sound is noisy. Therefore, the top plate is held and opened by hand until the top plate is completely dropped. This is inconvenient for the cabinet user (operator) and the commercial value is not high. Therefore, the present invention
Simple and quality operation of cabinets and other furniture that can take things in and out, when opening / closing the door with a rotating operation of the lid such as a top plate, or moving the lid up and down to open / close the door. The aim is to provide high furniture.

Means for Solving the Problems In view of the above object, Claim 1
In this configuration, a pivotable guide body having a guide, which is rotatable about a pivot provided on the housing, and a sliding surface guided by the guide and slidable, is engaged with the pivotal guide body. And a lid member that rotates with the rotation guide body and is relatively movable in the guide direction of the guide with respect to the rotation guide body. Furniture, comprising: a slanted inclined surface; and a ball interposed between the inclined surface and the sliding surface. The term “sliding” as used in the present application includes not only a state of constant contact but also a state of contact and separation. The lid member that is rotatable and rotates by engaging with a rotation guide body having a guide has a sliding surface that is guided by the guide and slides,
A ball body is interposed between this and the inclined surface provided on the rotation guide, and the rotation guide is rotated to incline,
When the lid member is dropped in the guide direction of the guide of the rotating guide body and in the direction in which the distance between the sliding surface and the inclined surface is reduced, the ball body is moved in the direction in which the ball member is reduced, and the sliding surface and the inclined surface are inclined. Since the ball is held between the ball and the surface, the ball has a large resistance to rotation or slip. In this way, since the lid member falls while receiving the resistance (rotational resistance or sliding resistance) of the ball body to the sliding surface, even if you release your hand and let it fall vertically, the falling speed is slowed down more than the natural fall. . Therefore, the operator only has to rotate the lid member and then release his / her hand, and can easily open or close the take-out port. Conversely, if the lid member is to be lifted in the direction in which the distance between the sliding surface and the inclined surface increases, the ball moves in the direction in which the distance widens, and the resistance of the ball disappears. It can be pulled up with a slight force, and then can be rotated together with the rotation guide to close or open the take-out opening.

According to a second aspect of the present invention, a hinge is attached to the upper rear portion of the housing via a hinge having a pivot extending in the left-right direction, and is rotatable. It is guided and slid, has sliding surfaces parallel to each other as a pair on the left and right, engages with the rotating guide, rotates together with the rotating guide, and moves with respect to the rotating guide. And a lid member which is relatively movable in the guide direction of the guide, and which is provided on the left and right sides of the rotating guide body, and which is inclined symmetrically to the left or right guide so as to become narrower toward the hinge side with respect to the guide direction of the left or right guide. Furniture, comprising: a pair of inclined surfaces; and a ball interposed between each of the inclined surfaces and each of the adjacent sliding surfaces. In addition to having the same function and effect as the first aspect, since the rear portion has the pivot, the lid member can be dropped and stored on the back side of the furniture only by flipping up while holding the front portion of the lid member. . Furthermore, since both inclined surfaces are provided on the left and right sides of the rotating guide so as to be inclined at the same angle (symmetrical with respect to the guide direction) of the guide, the left and right resistance forces received by the lid member from the ball are the same. Since the left and right balance is obtained when the lid member relatively moves so as to slide with respect to the rotary guide, the lid member can move smoothly.

According to a third aspect of the present invention, the rotary guide has guides on both left and right sides, and each of the guides is formed by attaching a separate member to a main body of the rotary guide. Provide furniture. In general, the body of the rotating guide body can be made inexpensive by bending or pressing a thin steel material or the like, and if this body or a material made of wood is used as a guide as a guide, it cannot be said that the guide has sufficient slipperiness. The smooth relative movement of the lid member is hindered. Also, the guide wants to improve durability or exchangeability. Therefore, if the guide is constructed by attaching a member different from the main body of the rotation guide body, there is no need to bend or press, so that a material that is slidable arbitrarily can be selected, or a material that is difficult to wear can be selected. Or, even if worn out, it can be replaced at low cost.

According to a fourth aspect of the present invention, a lid member having a sliding surface guided vertically by a guide provided on the housing and sliding vertically is provided on the housing, and a cover member provided on the housing and arranged in the guide direction of the guide. Furniture is provided, comprising: an inclined surface that is inclined with respect to the lower surface so as to be narrower, and a ball interposed between the inclined surface and the sliding surface. Other than the absence of the rotation guide of claim 1, the same operation and effect can be obtained.
A brief description will be given. Note that the vertical direction includes not only the vertical direction but also the inclined direction. A ball is interposed between the sliding surface of the lid member and the inclined surface provided on the housing, and if the lid member is dropped in a downward direction for guiding the guide, the ball body is brought into contact with the inclined surface and the sliding surface. The ball is moved in the downward direction, and the resistance of the ball increases. Since the lid member falls while receiving the resistance (rotational resistance or sliding resistance) of the ball body to the sliding surface, even if the hand is released and dropped vertically, the falling speed is correspondingly reduced compared to the natural fall. Therefore, the operator may release his hand from the lid member, and can easily open and close the take-out port. Conversely, when the ball is lifted upward, the ball moves in the direction in which the interval increases, so that the resistance of the ball is eliminated, and the ball can be lifted with a force about the weight of the lid member.

According to a fifth aspect of the present invention, there is provided the furniture according to the fourth aspect, wherein the housing has guides on both right and left sides, and each of the guides is configured by attaching a separate member to a main body of the housing. In general, the main body of the housing can be made inexpensive by bending or pressing a thin steel material or the like, and if this main body or a main body made of wood is used as a guide as it is, stability and slipperiness can be obtained as a guide. However, the relative movement of the lid member is hindered. Also, the guide wants to improve durability or exchangeability. Therefore, if the guide is configured by attaching a different member from the main body of the housing, there is no need to bend or press, so it is possible to select a material that is slidable arbitrarily, or a material that is hard to wear,
Or, even if worn out, it can be replaced at low cost.

According to a sixth aspect of the present invention, there is provided the furniture according to any one of the first to fifth aspects, wherein the sliding surface is formed by attaching another member to a main body of the lid member. Generally, the main body of the lid member is formed by bending or pressing a thin steel material or the like, and if this main body is used as a sliding surface as it is, the sliding property is not sufficient as a sliding guide surface. The rigidity is not sufficient, and smooth relative movement of the lid member is hindered. Also,
Easy to wear and poor durability. Therefore, if a separate member is attached and a sliding surface is provided on this, it is not necessary to bend or press, so it is possible to select a material that is difficult to wear or to select a desired thickness, and a stable sliding surface can be obtained. Can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is a perspective view of a drawer-type file cabinet as an example of furniture according to the present invention, FIG. 2 is a use state diagram, and FIG. 3 is an operation explanatory diagram by a cross-sectional view taken along line CC of FIG. . The housing 10 is formed by bending a plate-like steel material, for example.
A rectangular parallelepiped housing is formed by connecting main body members such as the left side plate 10A, the right side plate 10B, the upper front plate 10C, the upper rear plate 10D, the lower front plate 10E, and the rear plate 10F. The front side of the housing 10 is open, and a three-stage drawer 1
2A, 12B and 12C are sequentially arranged from the top. These drawers can be pulled out as usual, and files can be taken in and out.

On the other hand, the upper part of the housing is also open, and a top plate 16 as a kind of lid member is provided here. The main body of the top plate is also formed by bending a plate-like steel material. The top plate can be moved by a mechanism to be described later, and when it is opened, it can reach the first stage drawer 12A from the opening. Therefore, stored items such as files can be taken out or put in from the upper part of the cabinet. In addition, if the drawer 12A of the first stage is pulled out and the top plate 16 is opened, the drawer 12B of the second stage can be reached.

At the rear end of the upper rear plate 10D, a rectangular turning guide 14 is attached by a hinge 20 having a pivot 18 extending in the left-right direction. The main body of the rotation guide body 14 is also formed of a plate-like steel material. The top plate 16 is housed and engaged in a later-described left and right edge flange of the top plate so as to cover the rotation guide body. Together with the rotary guide, and is relatively movable with respect to the rotary guide substantially along the left and right sides of the rotary guide. As a result, when the finger is locked on the handle 16A of the top plate 16 placed horizontally on the upper part of the housing, and the top plate is pulled up, the rotation guide 14 is pivoted to the pivot 18
, While turning around to the position indicated by the two-dot chain line 14 ′. At this time, the top plate also turns and moves to the position indicated by the two-dot chain line 16 ′. After that, the vertical position 16 ”
If the user releases his / her hand before or before rotating to (14 ″), the top plate 16 can be dropped and stored on the back side of the housing 10.

A configuration devised so as to be able to drop gently at the time of the drop will be described with reference to FIGS. FIG. 4 is an exploded view in which the rotation guide 14 and the top plate 16 are separated from the housing, and FIG. 5 is a top view in a state where the rotation guide 14 and the top 16 are engaged (assembled). FIG. 6 is an enlarged partial view from the back side of the plate, and FIG. 6 is an enlarged cross-sectional view taken along line FF of FIG. 5. Top plate body 1 formed from sheet steel
At the left and right edges bent in a U-shape of 6H, a linear long material 16GB having a rectangular cross section made of stainless steel is provided along the inner side surface of the edge. Chrome-plated steel may be used instead of stainless steel. One side of the rectangle of the long material, the facing surfaces of the left and right long materials,
That is, the left inner surface 16G and the right inner surface 16G 'are sliding surfaces. Since it is made of stainless steel, it is hard, can maintain linearity, and does not easily wear. Further, even a chrome-plated one is hard and hard to wear.

On the other hand, the main body 14H of the plate-shaped steel material of the rotation guide body 14 is formed by bending right and left edges into a U-shape, and the inner surface of the main body 14H faces the inner surface of the top plate main body 16H. It is arranged. Hereinafter, the left side will be mainly described, but the right side is also configured to be symmetric with the left side as described later. A rectangular hole 14A is provided at a predetermined position on an edge surface 14M of the left U-shaped edge portion facing the sliding surface 16G of the long material. Further, an L-shaped steel member 24 whose two surfaces are orthogonal to each other is fixed to the inner surface side of the main body 14H, and the edge surface 1 of the L-shaped steel member provided with the hole 14A is provided.
The surface 24K facing the 4M side is inclined with respect to the edge surface 14M of the rotation guide. Moreover, the rotation guide 14
Are fixed to the hinge 20 so that the distance between the edge surface 14M and the inclined surface 24K increases as the distance from the hinge increases. In the embodiment, the inclination angle θ is about 6 degrees. The edge surface 14M of the rotation guide body described here is
The same is true even if a guide surface of a guide body described later is used.
The L-shaped steel material 24 is not limited to a steel material, and may be made of a synthetic resin material.

Before the top plate is engaged with the rotation guide 14, a steel ball 22 is inserted into the inside from the hole 14A. Instead of the steel ball 22, a sphere made of resin may be used. The distance between the edge surface 14M and the inclined surface 24K is the longitudinal end of the rectangular hole 14A, and the distance between the edge surface 14M and the inclined surface 24K.
At the end (lower side in FIG. 5) where the distance between the steel ball 22 and the steel ball 22 in contact with the inclined surface 24K protrudes from the edge surface 14M, and the other end of the hole 14A (FIG. 5). In the upper side), whether the steel ball 22 does not protrude from the edge surface 14M,
Alternatively, it is set so as not to protrude beyond a line (surface) connecting both guide surfaces of the guides 14GU and 14GS attached to the left U-shaped edge of the rotation guide body 14H described later.

As shown in FIG. 4, an L-shaped steel material 24 'is fixed to the left and right sides of the rotation guide body 14 at positions symmetrical to the above-described L-shaped steel material 24, and both steel materials 24, 24'. Outside inclined surfaces 24K and 24K 'are also symmetrical to each other,
Right edge surface and inclined surface 24K 'and right guide body 14G
The distances between U ′ and 14GS ′ and the guide surface are all symmetrical.

Since a gap of about several millimeters is provided between the edge surface 14M of the rotation guide body 14H and the sliding surface 16G of the long member 16GB of the top plate 16, the edge surface 14M is slid. Face 1
It cannot be a guide surface for 6G. This is because the main body 14H made of a normal plate-like steel material is used as the guide surface as it is because it is easily worn and is not suitable for replacement when worn, and the slipperiness is not good. .
Therefore, the guide body 14G is formed by using a material having a thickness dimension capable of substantially filling the gap and having good slipperiness, such as a synthetic resin material such as polyamide or polyacetal.
U and 14GS are attached to the upper and lower portions of the U-shaped edge of the main body 14H.

Therefore, when the top plate 16 slides with respect to the rotary guide 14, the four guides 14GU, 14GS, 14GU ', 14GS'
It is guided by a guide surface facing the sliding surfaces 16G, 16G 'of the long material. When the top plate 16 is dropped and stored on the back side of the cabinet, the top plate 16 falls while being guided by the guide body at the initial stage of dropping. However, the steel ball 22 immediately loses the distance between the inclined surface 24K and the edge surface 14M. It moves downward to become narrower, and the surface of the steel ball comes into contact with the sliding surface 16G of the top plate. That is, the top plate moves downward (falls) while the steel ball is sandwiched between the inclined surface and the sliding surface. Therefore, the top plate is subjected to sliding friction after rolling friction from the steel ball 22 via the sliding surface (the rolling friction is only for a moment, and is almost always sliding friction). Therefore, unlike a free fall, it falls slowly and an impact or the like is prevented.

When the top plate is pulled up to cover the opening (inlet), the steel ball 22 is moved upward (in a direction in which the distance between the inclined surface and the sliding surface becomes large) due to friction with the sliding surface. It is moved and the frictional force against the sliding surface does not act.
Therefore, it can be easily pulled up with a force about the weight of the top plate.

Strictly speaking, since a slight gap is also provided between the sliding surface of the top plate and the guide surface of the guide body, the top plate 16 is guided up and down along the guide surface of the rotary guide 14. In this case, the sliding surface does not always move while always contacting the entire guide surface.
U and the lower guide body 14GS 'at the right edge, and at the other moment, the lower guide body 14GS at the left edge and the upper guide body 14GU' at the right edge. Therefore, the term “sliding” as used in the present application includes not only a state of constant contact but also a state of contact and separation.

In the above description, the cabinet is of the drawer type, but instead of the drawer type, it may be a cabinet of a door type or the like which opens right and left, or may be furniture of other types. Further, although a top plate (a cover that is substantially horizontal and covers the cover) is illustrated as an example of the cover member, a cover that is used vertically or may be used in an inclined shape may be used. For example, in a furniture in which a lid member is guided up and down with respect to a housing to open and close an entrance, there is no rotation guide 14 as described above, and guides are provided on the left and right sides of the housing. , An inclined surface is also provided on the housing. Also in the case of such a structure, the falling speed can be moderated by the action of the ball body such as a steel ball, the inclined surface, and the sliding surface.

[0022]

As is apparent from the above description, according to the present invention, it is possible to open and close a door of a furniture such as a cabinet or the like which can take in and out a storage object by rotating a lid member such as a top plate with a rotating operation. It is possible to provide high-quality furniture that is easy to operate when opening and closing the door by moving the lid member up and down.
