[0002]

BACKGROUND OF THE INVENTION A rotating mirror type dresser 2 called a writing dresser or a dresser desk.
1 is used as a dresser in a state in which the top plate 3 is lifted upward as shown in FIG. 1 and the mirror on the back surface tilts the upper end backward. When adopting such a configuration, a metal fitting or the like that guides the opening / closing plate 4 forming a part of the top plate 3 freely is required, but this type of dresser 2 is also important in terms of design finish. Therefore, a hinge that is easily visually recognized is not often attached to the rotating end. Instead, a member for opening and closing is used at the edge of the opening and closing plate 4 side that is difficult to see.

As shown in FIG. 6 (a), the conventional type of this type includes a guide rail 11A, a sagittal link 12A having a sliding end 20A moving along the guide rail 11A, and an intermediate portion of the sagittal link 12A. A restriction link 1 for rotatably connecting the restriction end 19A of the guide rail 11A.

Is being guided. Then, the sliding state of the sliding end 20A is made smooth, and the lifting angle (backward tilt angle) of the opening / closing plate 4A is increased.
End 20A of the suspension link 12A to regulate
A regulating plate S that slides on the rail was provided on the side. However, in this method, the contact area between the regulation plate S and the guide rail 11A is large, so that there is a problem in that the movement is not smooth.

Therefore, as a countermeasure against this, as shown in FIG. 6 (b), the upper portion of the regulating plate S is cut out, and the lower surface alone is brought into contact with the guide rail 11A. Although the above-mentioned problems of the conventional type have been improved by such measures, the restriction plate S and the guide rail 11 are still present.
The fact that A and A rub against each other within a certain range is the same, and it is not a fundamental solution. In addition, in this case, if considered as a component in this case, so-called right-handed and left-handed ones must be separately prepared for attachment to the left and right side edges of the opening / closing plate 4A, and thus sharing of components cannot be achieved.

[0005]

[Technical Items Attempted to Develop] The present invention has been made on the basis of the recognition of such a background, and it is possible to smoothly perform the opening / closing operation of the opening / closing plate and the like, and it can be used as a left-right common component. This is an attempt to develop a new and improved samurai guidance member.

The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 is a sagging guide member according to the present invention, which is applied to a dresser 2 which is one of the furnitures to which the present invention is applied. Specifically, it is attached in order to open and close the opening / closing plate 4 which constitutes a part of the top plate 3 of the dresser 2. Reference numeral 5 is an opening / closing plate mounting portion configured so that a part of the top plate 3 is hollowed out to accommodate the opening / closing plate 4.

The samurai guiding member 1 will be described in detail below. This is, for example, configured by combining metal materials and the like in a link shape. Of course, the material may be a synthetic resin or a composite material of a synthetic resin and a metal as long as the same purpose can be achieved. The constituent members are roughly classified into a guide rail 11, a samurai link 12, and
The restriction link 13 will be described below for each of these members.

First, the guide rail 11 has a long rod shape as a whole, and when viewed in cross section, a flange portion 16 is formed above and below the substrate portion 15, and substantially the flange portion 16 is formed.
A guide groove 17 is formed on one surface of the substrate portion 15 so as to be surrounded by. In addition, a screw hole 18 for attachment is formed at an appropriate position in the substrate portion 15. Reference numeral 19 is a restriction end to which one end of the restriction link 13 is fixed.

A suspension link 12 is attached to the guide rail 11 so as to perform a suspension movement. That is, the sliding end 20 of the samurai link 12 slides along the guide rail 11, and this end is almost pointless with the guide rail 11 in order to make the sliding state smooth. Make contact. Specifically, the rotatable sliding roller 21 is attached here. This sliding roller 21
Has an engaging groove 22 on the outer periphery at a position where it is fitted into the guide groove 17, and the engaging groove 22 fits with the flange portion 16 and maintains the retaining relationship. Since the binding link 12 is attached to the opening / closing plate 4, the screw hole 23 is provided at an appropriate position like the guide rail 11 described above. In this specification, the point contact state includes not only a point contact in a strict sense but also a state in which the point contact continuously becomes a line contact in the width direction of the guide groove 17. Therefore, for example, in FIG. 3B, the width of the flange portion 16 and the width of the engagement groove 22 may be increased so that the flange portion 16 and the engagement groove 22 are substantially in line contact with each other. As another example in which the sliding end 20 of the suspension link 12 is brought into contact with the guide rail 11 in a point contact state, for example, FIG.
As shown in FIG. 3, the sliding end 20 is provided with a sliding block 25 having a small-diameter roller 25a on the upper and lower sides thereof.
Rolling the guide groove 17 inside the guide groove 17
The sliding end 20 in 2 may be moved.

The regulation link connection portion 24 is provided at a substantially intermediate point of the samurai link 12, which is a so-called pin link connection. The restriction link 13 connected here will be described below. The regulation link 13 has one end that is rotatably connected to the regulation link connection portion 24 as a suspension link regulation end 30 and the other end as a guide rail connection end 31. By the way, Abuse Link 12
Since the movement or the backward tilt angle in the fully opened state is appropriately set by the length of the regulation link 13, the position of the regulation link connecting portion 24, etc., those positions can be appropriately selected according to the purpose. It is a thing. Of course, it is also regulated by the length of the stopper 32 described later. Further, although the guide rail connecting end 31 is provided at the center of the vertical height of the guide rail 11 when viewed from the side in this embodiment, it does not necessarily have to be provided at the center. It does not matter if it is provided at a position close to one of the upper and lower ends of 11 or at a projecting position. Of course, when the guide rail connecting end 31 is located at the center of the guide rail 11 in the height direction, it is preferable in that the left and right members can be shared. Further, a stopper 32 is provided from the guide rail connecting end 31 so as to close the guide groove 17 so that the sliding end 20 of the suspension link 12 slides toward the sliding side 20.

The sagging guide member 1 of the present invention has a specific mechanism as described above, and it is used as follows. First, when mounting this, as shown in FIGS. 1 and 2, the guide rail 11 is screwed to a position facing the side end surface of the opening / closing plate 4 in the opening / closing plate mounting portion 5 of the dresser 2 or the like. Attach the binding link 12 to the side edge.

In order to perform the opening / closing operation in such a state, it suffices to hold the free end side of the opening / closing plate 4 by hand and handle it like opening. In this case, the sliding end 20 of the binding link 12 is lifted while being guided along the guide rail 11, and is stopped in a state in which the sliding end 20 is tilted backward at a certain angle, for example.

In order to use the binding guide members 1 attached to the left and right in the opposite directions, the binding links 12 are turned downward from the state parallel to the guide rails 11 as shown in FIG. When it is moved and the sagging guide member 1 is rotated 180 ° to turn it upside down, the same usability can be achieved for both right and left sides.

[0021]
