DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a pair of left and right columns (4) and (4) in which a cabinet (1) (1) with a flap door to which the present invention is applied is erected on the rear end of a top plate (3) in a desk (2). In this example, two side plates are arranged side by side in the left-right direction by joining the side plates to each other.
[0012]
As shown in FIG. 2, each cabinet (1) has a column (4) via a support plate (6) on the rear side of the lower surface of the side end of the rectangular box-shaped housing (5) whose front is opened. By being fixed to the upper end of the column, it is supported by being slightly deviated forward from the center of the column (4).
[0013]
A flap door (7) having a rectangular shape large enough to cover the front opening of the housing (5) is provided so as to be able to flip up while being guided by a guide mechanism described later.
[0014]
The flap door (7) includes a thin hollow door body (7a) formed of a transparent or semi-transparent synthetic resin material, and end caps (7b) (7b) (fitted on both right and left ends). 7b), and the end cap (7b) is formed of a non-transparent synthetic resin material.
[0015]
The door body (7a) is reinforced by a plurality of upper and lower flat ribs (8) connected between the front and rear facing surfaces inside the door body (7a).
[0016]
The front surface of the door body (7a) is an arcuate surface that bulges smoothly forward, and a protrusion (9) protruding forward is formed at the lower end of the door body (7a) over the entire length in the left-right direction. (9) functions as a finger hook when closing the flap door (7) opened to the upper limit position, as indicated by the two-dot chain line in FIG.
[0017]
Moreover, in order to enhance the design effect, a plurality of upper and lower concave grooves (10) are formed on the front surface of the door body (7a) over the entire length in the left-right direction (see FIG. 3).
At the upper end of the rear surface of the door body (7a), there is a hollow duct-shaped closing rod (11) projecting backward to close the gap between the left and right guide rails (17), which will be described later, over the entire length in the left-right direction. It is connected continuously.
[0018]
The front and rear dimensions of the closing rod (11) and the guide rail (17) to be described later are substantially equal.
[0019]
On the lower end of the rear surface of the door body (7a), a concave groove (12) facing in the left-right direction is formed, and this concave groove (12) functions as a finger hook when opening the flap door (7), A holding means for holding the flap door (7) in a closed state, for example, a magnet catch (13) is provided as an attachment portion.
[0020]
The end cap (7b) is formed so that the vertical dimension and the shape of the front and rear surfaces are substantially the same as the door body (7a), as shown in FIG. The fitting piece (15) having a holding piece (14) that can be fitted into the hollow hole at the side end of the door body (7a) and that can hold the upper and lower ribs (8) from above and below is integrally formed. Are connected continuously.
[0021]
The flap door (7) is assembled by press-fitting the fitting pieces (15) of the left and right end caps (7b) into the hollow holes at both end portions of the door body (7a).
[0022]
As shown in FIG. 2 , on the rear surfaces of both side ends of the flap door (7), that is, on the rear surfaces of the left and right end caps (7b), as shown in FIG. A rearwardly U-shaped guide rail (17) having is attached.
[0023]
When the guide rail (17) is attached, a gap is formed between the front end of the housing (5) and the rear surface of the door body (7a) between the guide rails (17). The main body (7a) is closed by the closing hook (11) protruding from the upper end of the rear surface.
[0024]
In the U-shaped space of each guide rail (17), it rotates around an axis that is pivotally attached to a bracket (18) fixed to the front end of the upper plate (5a) of the housing (5) and that faces in the left-right direction. A guide roller (19) is inserted.
[0025]
When the flap door (7) is in the closed state, the guide roller (19) contacts the upper stopper piece (16), and the flap roller (7) is also positioned at the upper horizontal position as indicated by a two-dot chain line. When it is opened, it comes into contact with the lower stopper piece (16) and slightly protrudes from the front end of the housing (5).
[0026]
For example, a known load balance device (20) in which a spiral spring (not shown) is housed is attached to the inner side surface of the left and right side plates (5a) in the housing (5), and extends obliquely downward therefrom. The tip of the rotating arm (21) is pivotally attached to the lower end of the guide rail (17).
[0027]
The load balancer (20) supports the flap door (7) with an upward biasing force slightly larger than its weight, so that the flap door (7) can be opened easily.
[0028]
In the cabinet with a flap door (1) of the above embodiment, the door body (7a) is formed of a light-transmitting material, so that the flap door (7) is formed as shown by a two-dot chain line in FIG. Even if it opens to the upper limit position and protrudes like a bowl in front of the housing (5), the protrusion blocks the light of the ceiling lighting fixture or casts a shadow on the top plate (3) of the desk (2) The top surface of the top plate (3) is prevented from becoming dark.
[0029]
In addition, when looking up, the protruding portion becomes less conspicuous, so that the appearance is good and the feeling of pressure is reduced.
Since the end cap (7b) at the side end of the flap door (7) is opaque, when the flap door (7) is closed, the guide rail (17) attached to the rear surface is transmitted from the front. It doesn't appear and looks better.
[0030]
Since the door body (7a) is formed of a synthetic resin material in a hollow shape, the door body (7a) is light and easy to open and close the flap door (7).
[0031]
Further, since a finger-hanging protrusion (9) is formed on the lower front portion of the door body (7a), the operation when closing the opened flap door (7) is facilitated.
[0032]
In addition, a closure rod (11) is provided at the upper end of the back surface of the door body (7a) to block the upper part of the gap between the housing (5) and the door body (7a) between the left and right guide rails (17). Therefore, it is possible to prevent dust and the like from entering the cabinet.
Further, since the closing rod (11) also has a reinforcing function, the bending of the door body (7a) is also prevented.
[0033]
In the above embodiment, the entire door body (7a) has translucency, but only the portion protruding forward from the housing (5) when the flap door (7) is opened is translucent. Other portions may be opaque.
[0034]
As this method, for example, the entire door body (7a) may be formed of a light-transmitting material, and the portion excluding the protruding portion may be colored by painting or the like, or an opaque adhesive tape or the like may be pasted.
The end cap (7b) may also be translucent to such an extent that the guide rail (17) cannot be seen through.
Instead of the guide roller (19), a guide pin facing in the left-right direction may be used, and this may be slidably engaged with a guide groove formed in the guide rail.
[0035]
【The invention's effect】
According to the first aspect of the present invention, the gap at the upper end between the left and right guide rails generated when the flap door is closed is substantially closed by the closing member projecting from the rear surface of the flap door. Dust and the like are prevented from entering the fixture body.
Moreover, since the closing member is integrally connected to the flap door so as to close the gap between the left and right guide rails, the flap door is reinforced and the flap door is prevented from being bent. .
[0036]
According to the second aspect of the invention, since the closing member can be integrally formed simultaneously with the resin molding of the flap door, it is possible to prepare a closing member as a separate member or to omit troublesome attachment work. Cost reduction is possible .
[0037]
According to the invention described in claim 3, since the flap door and the closing member can be reduced in weight, the flap door can be opened and closed easily.
[0038]
According to the fourth aspect of the invention, when the flap door is closed from the horizontal open position, the protrusion can be rotated downward with the protrusion as a finger-hanging portion, so there is no fear of the finger slipping and the flap door closing operation. Becomes easy.
