Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a worktop receiver for a writing desk.

Conventionally, as illustrated in FIG. 1, the above-mentioned worktop receiving device has been provided with the doors a, a in an open state, and the doors a,
A device is known in which a worktop b which has been rotated and lowered at point a is supported.

However, with the above configuration, if the depth of the desk body C is particularly small, when a large force is applied to the worktop b, it tends to fall toward the front, and the hinges of the doors a and a are
A large moment acts on the hinge, making it easy to damage the hinge.In order to improve this problem, casters, adjusters d, etc. are already installed at the lower ends of doors a and a.

However, by using an adjuster, etc. in this way, the above disadvantages can be eliminated to a large extent).Since the adjuster, etc. is attached to the tip of door a, force is applied to the hinge, and door a,
In order to support the load of worktop b by a, door a,
The strength of a must be increased to a certain extent, and therefore, if the door a is made of glass, it may be less strong than a door made of wood or the like, and it may be difficult to use.

Furthermore, according to the conventional example, even when the door is closed when not in use, the adjuster d and the like are inevitably exposed, resulting in an unsightly appearance.

Therefore, the present invention was developed in consideration of the above-mentioned conventional circumstances, and was developed as a result of the fact that the load on the door and its hinge is extremely small, so even doors with low strength can be used without worry, and when the door is closed when not in use. Since all the devices are housed within the desk body, the appearance can be improved, and the operation of the device is linked to the opening and closing of the door, eliminating the need for special operations, improving usability. A worktop receiving device was obtained.

The present invention will be described below based on the illustrated embodiment. First, as shown in FIGS. 2 to 4, the front opening 1a of the desk body 1 has a worktop 2 and two double doors. 3
, 3 are arranged vertically, respectively, and the worktop 2 can be opened and closed in the vertical direction, while the doors 3 and 3 are pivotally connected by lower and left and right hinges 4 and 5, respectively, so that they can be opened and closed in the left and right directions.

In this case, when the worktop 2 and both doors 3.3 are in use, the worktop 2 fits inside the doors 3, 3, and is not held by the doors 3, 3. It is better to set the pivot as shown.

In the worktop support device according to the present invention, the worktop support rod 8 is mounted substantially vertically with the pin 6 at the tip of each of the two parallel upper arms 6 and lower arm 7 so that the overall shape is approximately U-shaped. ', ? The base ends of the two horizontally oriented upper arms 6 and lower arms 7 are respectively supported near the door pivot portion on the inner surface of the side plate 1b of the desk body 1.

In this case, the supporting means is pivotally mounted so as to be rotatable in the opening/closing direction of the doors 3, 3 and in the vertical direction perpendicular thereto, and is biased with a lifting force by a spring 9.
In addition, in order to be able to interlock with the opening and closing of the doors 3, 3, the tips of both the upper and lower arms 6.7 are located on the inner surfaces of the doors 3, 3, and are fixed to the upper and lower parts thereof, respectively. The worktop 2 is hooked to the letter-shaped hooks 10 and 11 in a vertically movable and detachable manner while preventing upward movement, and when the doors 3, 3 are open, the worktop 2 is attached to the upper end surface of the worktop holder 8. It is structured so that it can be used in a horizontally equal manner.

In this case, the upper arm 6 and the lower arm 7 are pivotably mounted to enable free opening/closing and vertical movement, and as heating means for applying lifting force, the fifth
As illustrated in the figure, a coil spring 9 and a mounting member 12 formed by protruding a mounting shaft 12b from the bottom of a U-shaped member 12a are used.

That is, the base ends of the upper arm 6 and the lower arm 7 are pivoted between both brackets 12c, 12c of the U-shaped member 12a of the mounting member 12 by a vertical pivot 13 so as to be rotatable in the opening/closing direction of the door 3, This mounting member 12 has its mounting shaft 12b engaged with a bearing 14 driven into and fixed to the side plate 1b of the desk main body 1 so as to prevent it from coming off in the axial direction and to be rotatable around the axis. The lower arm 7 is pivoted so that it can rotate in the vertical direction.

On the other hand, when a coil spring 9 is used as a heating means for applying lifting force to both the upper and lower arms 6.7 as shown in the figure, it is mounted on the mounting shaft 12b, and one end of the coil spring 9 is attached to the side plate 1b of the desk main body 1 or It is hooked to a fixed side such as a bearing 14, and the other end is hooked to the U-shaped member 12a so as to be able to rotate it upward.

The lifting force is applied to the upper arm 6 and the lower arm 7 in this way because the lower end of the worktop holder 8 is connected to the door 3.
, 3 protrudes downward from the lower end of the worktop holder 8 to prevent the lower end of the worktop holder 8 from hitting the base plate 1c of the desk main body 1 when the door is closed, so that it can be linked to the opening and closing of the door 3゜3, and when the desk is not in use. This is so that it can be accommodated within the main body 1.

Therefore, when the worktop 2 is not supported, it is in a lifted state as shown by the solid line in FIGS. 2 and 3, and when the worktop 2 is supported, it resists the elasticity of the spring 9 due to its weight. As shown by the two-dot broken line in FIG. 2, the worktop support rod 8 comes into contact with the floor surface 15, etc., thereby supporting the worktop 2 in the use state.

Also, if it is necessary to specify the opening angle of doors 3, 3,
As shown in FIG. 5, the upper arm 6 and the lower arm 7
By screwing the adjuster 16 near the pivot point of the desk body 1, or by standing a stopper pin on the main plate 1c of the desk main body 1 (not shown) so that the adjuster 16 butts against the side plate 1b of the desk main body 1, or by screwing the adjuster 16 near the pivot point of the lower arm 7. The desired opening angle can be obtained by hitting the stopper pin.

Further, an adjuster 17 may be attached to the lower end of the worktop support 8 as shown in the illustrated example.

In addition, both the upper and lower arms 6.7 and the work top holder 8 are attached to the upper and lower arms 6.7 with the hook 10.1.
1 to be linked to the opening and closing operations of the doors 3, 3, or it can be removed from the hooks 10 and 11 to rotate separately from the doors 3, 3.

As explained above, according to the worktop support device for a writing desk according to the present invention, the tips of the upper arm 6 and the lower arm 7, which are approximately U-shaped, are pivoted to the vertically installed worktop support 8. The sitting arm 6.7 is pivotally supported on the side plate 1b of the desk main body 1 so that it can rotate in the door opening/closing direction and in the up/down direction, and is biased by the lifting force of the spring 9, and is pivoted to open/close the door 3.3. The worktop 2 is hooked onto hooks 10.11 provided on the inner surfaces of the doors 3, 3 so as to be interlocked with the worktop holder 8, and the worktop 2 is held at the upper end of the worktop holder 8. The load can be fully supported by the worktop support 8 and not by the doors 3, 3, so a large force is applied to the doors 3, 3. Therefore, it can be used safely even on glass doors. As well,
Only the dead weight of the door 3 is applied to the hinge 5, and the weight of the worktop support device of the worktop support 8 and both upper and lower arms 6.7 is not applied to the doors 3, 3, so the hinge 5
Moreover, since the device can be closed while housed inside the desk main body 1 and is not exposed to the outside, it has a good appearance.Especially when this idea is used, the worktop holder 8 can be attached to both the upper and lower parts of the desk. It is supported by an arm 6.7, which both arms 6.7 have hooks 10, 1 provided on the inside of the door 3, 3.
1, so it can be linked to the opening and closing of the doors 3 and 3, and not only does it not require any operation to hold or release the worktop 2, but it also works in conjunction with the opening and closing of the doors 3 and 3. Since the worktop support 8 does not move when the worktop 2 is moved or when the worktop 2 is supported, the worktop 2 can be easily accommodated in the desk body 1 and pulled out.
It is possible to make the acceptance of the situation more stable.
