Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to furniture such as a pull-out cabinet for storing files.
[0002]
[Prior art]
In general, drawers such as drawer cabinets are pulled out to the front side to put in and out contents such as files. However, there are some that can open the top plate of the cabinet, and there is a form in which the top plate is dropped and opened on the back side of the cabinet. If the top is opened, the contents can be taken in and out from above, which may be convenient. For example, if there is a (temporarily) disturbing object in the front position of the cabinet, or the contents are stored only in the uppermost level, the cabinet will become unstable if it is pulled out. There are cases where necessary documents are stored in the rear part of the drawer, and it is desired to take in / out from the upper side rather than pulling out / in / out.
[0003]
[Problems to be solved by the invention]
However, when the top plate was dropped, an impact was applied and the top plate was damaged or the sound was noisy, so it was opened while being held by hand until the top plate was dropped. This is inconvenient for the cabinet user (operator) and does not have a high commercial value.
Therefore, the present invention can be used for opening / closing the entrance / exit by opening / closing the lid member such as a cabinet or the like, with a rotation operation of the lid member such as a top plate of the furniture such as a cabinet. The purpose is to provide high-quality furniture that is easy to operate.
[0004]
[Means for Solving the Problems]
In view of the above-mentioned object, in claim 1, there is provided a rotation guide body that can be rotated around a pivot provided in the housing, has a guide, and a sliding surface that slides while being guided by the guide, A lid member that engages with the rotation guide body and rotates together with the rotation guide body, and is relatively movable in the guide direction of the guide with respect to the rotation guide body; and the rotation guide body, Provided is a furniture comprising an inclined surface inclined with respect to a guide direction of the guide, and a ball body interposed between the inclined surface and the sliding surface. The term “sliding” as used in the present application is not limited to a state in which they are always in contact with each other, but also includes a state in which they are in contact with or separated from each other.
The lid member that can rotate and engages and rotates with the rotation guide body having the guide has a sliding surface that is guided by the guide and slides, and is provided on the rotation guide body. A ball body is interposed between the inclined surface, the rotation guide body is rotated and inclined, and the lid member is in the guide direction of the guide of the rotation guide body, and includes a sliding surface and an inclined surface. When dropping in the direction in which the interval is narrowed, the ball body is moved in the narrowing direction and is sandwiched between the sliding surface and the inclined surface, so that the rotational resistance force or sliding resistance force of the ball body increases. In this way, the lid member falls while receiving the resistance (rotation resistance or sliding resistance) of the ball body against the sliding surface, so even if it is released vertically, for example, the fall speed is correspondingly reduced compared to the natural fall. . Therefore, the operator may release the hand only by rotating the lid member, and can easily open or close the take-out port. On the contrary, if the lid member is pulled up in the direction in which the interval between the sliding surface and the inclined surface is increased, the ball body moves in the direction in which the interval is increased and the resistance of the ball body is lost, and the lid member has its weight. It can be pulled up with a certain amount of force, and thereafter it can be rotated together with the rotation guide to close or open the take-out port.
[0005]
In Claim 2, it is attached to the upper rear part of a housing | casing through the hinge which has the axis | shaft extended in the left-right direction, is rotatable, Comprising: The rotation guide body which has a guide on either side, It is guided by this guide It slides and has sliding surfaces parallel to each other in pairs on the left and right sides, engages with the rotation guide body and rotates with the rotation guide body, and the guide with respect to the rotation guide body A pair of inclined members which are provided on the left and right sides of the rotation guide body and which are relatively movable in the guiding direction, and which are inclined symmetrically so as to be narrower toward the hinge side with respect to the guiding direction of the left or right guide. There is provided a furniture comprising a surface, a ball body interposed between the inclined surfaces and the sliding surfaces adjacent to each other.
In addition to the same operational effects as in claim 1, since the rear part has a pivot, the lid member can be dropped and stored on the back side of the furniture simply by holding the front part of the lid member and jumping up. . Further, since the both inclined surfaces are provided on the left and right of the rotation guide body 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 body are the same. Thus, since the left and right balance is obtained when the lid member moves relative to the rotation guide body so as to slide, the lid member can move smoothly.
[0006]
According to a third aspect of the present invention, there is provided the furniture according to the first or second aspect, wherein the rotation guide body has guides on both right and left sides, and each guide is configured by attaching a separate member to the main body of the rotation guide body. To do.
In general, the main body of the rotating guide body can be made inexpensive by forming it by bending or pressing a thin steel material, etc.If this main body or a product made of wood is used as a guide as it is, it cannot be said that the sliding property is sufficient as a guide, Smooth relative movement of the lid member is hindered. In addition, the guide is desired to improve durability or exchangeability. Therefore, if the guide is configured by attaching a member other than the main body of the rotating guide body, there is no need for bending or pressing, so an arbitrarily slippery material or a material that does not easily wear is selected. Or, even if worn, it can be replaced at low cost.
[0007]
According to a fourth aspect of the present invention, there is provided a lid member having a sliding surface that is guided by a guide that guides in the vertical direction provided in the casing and slides up and down, and is provided in the casing and is inclined with respect to the guide direction of the guide And the furniture characterized by comprising the inclined surface inclined so that the downward direction may become narrow, and the ball body interposed between this inclined surface and the said sliding surface is provided.
Although there exists no rotation guide body of Claim 1, there exists the same effect, but it demonstrates easily. The vertical direction includes not only the vertical direction but also the inclination direction.
A ball body 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 the downward direction guided by the guide, the ball body has an inclined surface and a sliding surface. When the ball is moved downward, the resistance of the ball body 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 lid member is released vertically, the dropping speed is correspondingly reduced as compared with the natural falling. Therefore, the operator may release his / her hand from the lid member, and can easily open and close the outlet. On the contrary, when the ball body is pulled upward, the ball body moves in the direction in which the interval increases, so that the resistance of the ball body is eliminated, and the ball body can be pulled up with a force about the weight of the lid member.
[0008]
According to a fifth aspect of the present invention, there is provided the furniture according to the fourth aspect, wherein the case has guides on both right and left sides, and each guide is configured by attaching another member to the main body of the case.
It is the same as in claim 3, and generally, the main body of the casing can be made inexpensive by forming a thin steel material or the like by bending or pressing it. If this main body or a wood main body is used as a guide as it is, stability and slipperiness as a guide are achieved. Is not sufficient, and smooth relative movement of the lid member is hindered. In addition, the guide is desired to improve durability or exchangeability. Therefore, if the guide is constructed by attaching a member other than the main body of the housing, there is no need for bending or pressing, so a material that is arbitrarily slippery, a material that does not easily wear is selected, or Even if worn, it can be replaced at low cost.
[0009]
In Claim 6, the said sliding surface provides the furniture of any one of Claims 1-5 formed by attaching another member to the main body of a cover member.
Generally, the main body of the lid member is formed by bending or pressing a thin steel material, etc. If this main body is used as a sliding surface as it is, it cannot be said that the sliding property is sufficient as a sliding guide surface. The rigidity is not sufficient, and the smooth relative movement of the lid member is hindered. Moreover, it is easy to wear and lacks durability. Therefore, if another member is attached and a sliding surface is provided on this, it is not always necessary to bend or press, so it is possible to select a material that does not wear easily, or to select the desired wall thickness. Can be provided.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on an embodiment 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 view by a sectional view taken along line CC in FIG. . The casing 10 is formed by bending plate-like steel materials or the like and connecting main body members such as a left side plate 10A, a right side plate 10B, an upper front plate 10C, an upper rear plate 10D, a lower front plate 10E, and a rear plate 10F. Thus, a rectangular parallelepiped housing is formed. The front side of the housing 10 is open, and three-stage drawers 12A, 12B, and 12C are sequentially arranged from above. These drawers can be withdrawn forward and files can be taken in and out as usual.
[0011]
On the other hand, the upper part of the housing is also opened, and a kind of top plate 16 as a lid member is provided here. The main body of the top plate is also formed by bending a plate-shaped steel material. The top plate can be moved by a mechanism to be described later, and when it is opened, a hand can reach from the opening to the first-stage drawer 12A. Therefore, a stored item such as a file can be taken out or put in from the upper part of the cabinet. Further, when the first stage drawer 12A is pulled out and the top plate 16 is opened, the second stage drawer 12B can be reached.
[0012]
A rectangular rotation guide body 14 is attached to a rear end position of the upper rear plate 10D by a hinge 20 having a pivot 18 extending in the left-right direction. This rotation guide body 14 also forms a main body by a plate-shaped steel material. The top plate 16 is accommodated and engaged in flanges on the left and right edge portions of the top plate, which will be described later, so as to cover the rotary guide body. In addition, it can rotate with the rotation guide body, and is relatively movable relative to the rotation guide body along substantially the left and right sides of the rotation guide body. As a result, when the finger is locked to the handle portion 16A of the top plate 16 placed in a horizontal state on the upper part of the casing and the top plate is pulled up, the rotation guide body 14 rotates about the pivot 18. While rotating to a position indicated by a two-dot chain line 14 ', the top plate rotates and moves together to a position indicated by a two-dot chain line 16'. Thereafter, the top plate 16 can be dropped and housed on the back side of the housing 10 by moving it to a substantially vertical position 16 ″ (14 ″) or before releasing it.
[0013]
The structure devised so that it can fall gently when dropped will be described with reference to FIGS. 4 is an exploded view in which the rotation guide body 14 and the top plate 16 are separated from the casing, and FIG. 5 is a state in which the rotation guide body 14 and the top plate 16 are engaged (assembled). FIG. 6 is an enlarged partial view seen from the back side of the plate, and FIG. 6 is an enlarged cross-sectional view taken along line FF in FIG. On the left and right edges of the top plate main body 16H formed from a plate-shaped steel material, a straight long material 16GB made of stainless steel and having a rectangular cross section is disposed along the inner surface of the edge. Has been. Instead of stainless steel, a chrome-plated steel material may be used. One side of the long material rectangle, the opposing surfaces of the left and right long materials, that is, the left inner side surface 16G and the right inner side surface 16G ′ are sliding surfaces. Since it is made of stainless steel, it is hard and can maintain linearity and hardly wear. Moreover, even if it is chrome-plated, it is hard and difficult to wear.
[0014]
On the other hand, the plate-shaped steel body 14H of the rotation guide body 14 is formed such that the left and right edges are bent in a U-shape, and the inner surface of the main body 14H is disposed in a direction facing the inner surface of the top plate body 16H. ing. Hereinafter, the left side will be mainly described, but the right side is configured to be symmetrical with the left side as will be described later. A rectangular hole 14A is provided at a predetermined position of the edge surface 14M facing the sliding surface 16G of the long material of the left U-shaped edge. Furthermore, an L-shaped steel material 24 having two cross sections orthogonal to each other is fixed to the inner surface side of the main body 14H, and the surface 24K of the L-shaped steel material facing the edge surface 14M side provided with the hole 14A. Is inclined with respect to the edge surface 14M of the rotating guide body. Moreover, in a state where the rotation guide body 14 is attached to the hinge 20, the distance between the edge surface 14 </ b> M and the inclined surface 24 </ b> K is fixed so as to increase away from the hinge. As an example, this inclination angle θ is about 6 degrees. The edge surface 14M of the rotation guide body described here is the same even if it is replaced with a guide surface of a guide body described later. The L-shaped steel material 24 is not limited to a steel material and may be made of a synthetic resin material.
[0015]
Before the top plate is engaged with the rotation guide body 14, a steel ball 22 is inserted into the hole 14A. Instead of the steel ball 22, a resin sphere may be used. The distance interval between the edge surface 14M and the inclined surface 24K is the longitudinal end portion of the rectangular hole 14A, and the end portion where the interval between the edge surface 14M and the inclined surface 24K becomes narrow (in FIG. The steel ball 22 in contact with the inclined surface 24K protrudes from the edge surface 14M, and the steel ball 22 protrudes from the edge surface 14M at the other end (upper side in FIG. 5) of the hole 14A. Or set so as not to protrude beyond a line (surface) connecting both guide surfaces of the guide bodies 14GU and 14GS attached to the left U-shaped edge of the rotation guide body main body 14H described later.
[0016]
As shown in FIG. 4, L-shaped steel material 24 ′ is fixed to the left and right of the rotation guide body 14 in a symmetrical position with the above-described L-shaped steel material 24, and outside the both steel materials 24, 24 ′. The inclined surfaces 24K and 24K ′ are also symmetrical with each other, and the distance between the right edge surface and the inclined surface 24K ′ and the guide surfaces of the right guide bodies 14GU ′ and 14GS ′ is all symmetrical.
[0017]
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 in contact with the sliding surface 16G. It cannot be a guide surface. This is because the main body 14H manufactured from a normal plate-shaped steel material is used as the guide surface as it is because it is easy to wear and is not suitable for replacement when it is worn, and also because it is not good in sliding property. . Therefore, a U-shaped main body 14H is formed as a guide body 14GU, 14GS using parts having a thickness dimension that can substantially fill the gap and having a good sliding property, for example, a synthetic resin material such as polyamide or polyacetal. At the top and bottom of the edge.
[0018]
Therefore, when the top plate 16 slides with respect to the rotation guide body 14, the sliding of the long material of the four guide bodies 14GU, 14GS, 14GU ′, 14GS ′ provided on the left and right edge portions is performed. It is guided by a guide surface facing the moving surfaces 16G and 16G ′. When the top plate 16 is dropped and stored on the back side of the cabinet, the top plate 16 is dropped while being guided by the guide body at the beginning of the fall, but the steel ball 22 immediately has a distance interval between the inclined surface 24K and the edge surface 14M. The steel ball moves downward and becomes in contact with the sliding surface 16G of the top plate. That is, the steel ball moves (drops) downward while being sandwiched between the inclined surface and the sliding surface. Therefore, the top plate receives sliding friction after rolling friction from the steel ball 22 via the sliding surface (the rolling friction is only a moment, most of which is sliding friction). Therefore, unlike a free fall, it falls slowly and an impact etc. are prevented.
[0019]
When the top plate is pulled up and covered at the entrance / exit (opening), the steel ball 22 is moved upward (in the direction in which the distance between the inclined surface and the sliding surface increases) by friction with the sliding surface. The frictional force on the sliding surface does not work. Therefore, it can be easily pulled up with a force about the weight of the top board.
[0020]
Strictly speaking, since a slight gap is 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 rotation guide body 14. The sliding surface does not always move while being in contact with the entire guide surface. At a certain moment, the sliding surface comes into contact with the upper guide body 14GU at the left edge portion and the lower guide body 14GS ′ at the right edge portion. Is in contact with the lower guide body 14GS at the left edge and the upper guide body 14GU 'at the right edge. Accordingly, the term “sliding” as used in the present application includes not only a state where they are always in contact with each other but also a state where they are in contact with or separated from each other.
[0021]
In the above, the cabinet is a drawer type, but instead of the drawer type, a cabinet such as a door type that opens to the left and right may be used, or other types of furniture may be used. Furthermore, although the top plate (those that are generally horizontally covered) is illustrated as an example of the lid member, it may be used vertically or in an inclined shape. For example, in the furniture in which the lid member is guided in the vertical direction with respect to the casing to open and close the entrance / exit, there is no rotation guide body 14 as described above, and guide bodies are provided on the left and right sides of the casing. An inclined surface is also provided in the housing. Even in 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, and when it is pulled up, it can be pulled up with little resistance.
[0022]
【The invention's effect】
As is apparent from the above description, according to the present invention, a lid member such as a cabinet or the like for furniture that can be taken in and out is opened and closed with a turning operation, and the lid member is moved up and down. Thus, it is possible to provide simple and high-quality furniture that is easy to operate when opening and closing the entrance.
