Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table with a counter, more specifically, a counter mode in which a counter plate is positioned above a rear part of the table plate, and a table mode in which the rear end of the table plate is flush with each other. The present invention relates to a table with a counter that can be selected and can stably maintain both aspects.

[0002]

2. Description of the Related Art Conventionally, various types of tables with counters have been provided. For example, as disclosed in Japanese Utility Model Publication No. 2-32137, support plates having upper edges as stoppers are provided upright at opposite ends on one side in the depth direction on the surface of the table plate.
A pivot plate fixed to both sides of the counter plate is pivotally attached to the support plate, the counter plate is pivoted upward about the pivot point, and is mounted on an abutting portion of the support plate for use as a counter. It is also possible to use it as a wide table by rotating it downward and flush with the table plate.

However, in the above-mentioned table with a counter, when the counter plate is rotated downward to be flush with the table plate, the supporting plate and the rotating plate of the counter plate remain projected on the table plate. There was a problem in using it as a wide table as well as in appearance.

Therefore, the applicant of the present invention has proposed that
As disclosed in Japanese Patent Publication No. 7, the supporting plate rotates 180 degrees with respect to the table plate, and the rotating plate protruding from the lower surface of the counter plate slides with respect to the supporting plate to form a table mode. At times, there is provided a table with a counter having a structure in which no protrusion, that is, a supporting plate, is left on the table plate.

[0005]

However, in the one described in Japanese Utility Model Laid-Open No. 5-13227, the guide groove is formed continuously in an L shape along the two adjacent edges on the inner surface of the support plate. Since the guide means is formed by outwardly projecting the shaft body that is slidably engaged with the guide groove on the rotating plate projecting on the counter plate, the counter plate is changed from the counter mode to the table mode or vice versa. When it is moved, it requires a two-step sliding operation along the L-shaped guide groove and a rotating operation in the middle thereof, so that there is a drawback that it is difficult to change smoothly. Further, in the case of the table mode, there is a possibility that the support plate may unexpectedly rotate around the pivot point and may be lifted or rattled.

In view of the above-mentioned situation, the present invention is to solve the problem by moving the counter plate as in the conventional manner so that the counter mode and the table mode can be mutually changed, and the counter plate is supported in the table mode. In addition to the plate not remaining on the table plate, it is possible to smoothly and easily change it only by rotating operation, and to provide a table with a counter that can maintain the state of both modes extremely stably. .

[0007]

In order to solve the above-mentioned problems, the present invention provides a table main body having notches formed on both sides of a rear end of a table plate protruding rearward from a rear surface of the main body; One side of the plate-shaped member is a first mounting edge for mounting on the table plate, and the one end of the first mounting edge has a shape capable of compensating for the notch and the notch is provided in the front-back direction. A projecting portion pivotally attached so as to be rotatable by 180 degrees is provided in a projecting manner, a side adjacent to the projecting portion serves as a stop edge against the back surface of the table body, and a side facing the first mounting and supporting edge is the second mounting and supporting side. A pair of rimmed support plates;
A counter plate having a rotating plate protruding on both sides of the lower surface so as to be located inside the supporting plate, leaving the end portions thereof; a first mounting edge and a second mounting edge of the supporting plate A table with a counter is constituted by: a rotation guide means equidistantly located on the side opposite to the toe edge and on the side opposite to the stop edge;

Further, stopper means for restricting rotation of the rotating plate with respect to the support plate in a state in which the counter plate is placed on the second mounting / supporting edge of the support plate and a state in which the counter plate is mounted on the first mounting / supporting edge. Is preferably provided. Specifically, as the stopper means, an engaging pin is provided at an appropriate position of the rotating plate so as to be retractable in the direction of the supporting plate, and the counter plate is placed on the second mounting edge and the first mounting and supporting state. It is preferable to provide a stopper means provided with an engaging hole for engaging the engaging pin at each corresponding position of the support plate when placed on the edge.

Further, an arcuate edge centering on the pivot point of the rotation guide means is formed at the end edges of the first mounting edge and the second mounting edge on the side opposite to the stop edge of the support plate. What is done is also a preferred embodiment.

Furthermore, it is also a preferred embodiment that the notch of the table plate and the protrusion of the support plate are pivotally attached via a rotary damper having a large braking force for backward rotation.

[0011]

In the table with a counter of the present invention having the above contents, when the counter plate is placed on the second mounting edge with the first mounting edge of the supporting plate placed on the table plate, This is a counter mode in which the counter plate is located above the rear part of the table plate. Further, while maintaining the positional relationship between the support plate and the counter plate from the counter mode, the support plate is rotated downward by 180 degrees, and the rotating edge of the support plate is brought into contact with the back surface of the table body. When the counter plate is mounted on the first mounting edge by rotating the rotating plate upward by 180 degrees with respect to the support plate about the pivot portion of the table, and is joined flush with the rear edge of the table plate, This is a table mode in which the notch of the plate is filled with the protrusion of the support plate. In this table state, the center of gravity of the moving members such as the support plate, the rotating plate, and the counter plate is located below the pivot points of the notches and the protrusions, which is stable and the counter plate is unexpectedly lifted. There is no such thing. On the other hand, the change from the table mode to the counter mode is realized by reversing the above operation.

Further, stopper means for restricting rotation of the rotating plate with respect to the support plate in a state where the counter plate is placed on the second mounting and supporting edge of the support plate and a state in which the counter plate is mounted on the first mounting and supporting edge. In the counter mode in which the first mounting / supporting edge of the support plate is mounted on the table plate and the counter plate is mounted on the second mounting / supporting edge, the stopper means is operated for the support plate. By restricting the rotating plate of the counter plate, the supporting plate and the rotating plate do not move relative to each other due to the two-point support of the pivot point of the rotation guide means and the stopper means. Further, after the stopper edge of the support plate is brought into contact with the back surface of the table body, the stopper means is operated to release the rotation restriction, and the rotation plate is rotated with respect to the support plate about the pivotal portion of the rotation guide means. The counter plate is placed on the first mounting and supporting edge by rotating upward by 180 degrees and is joined flush with the rear edge of the table plate, and the stopper means is operated to regulate the rotation of the rotating plate with respect to the support plate. Then, the table is in a state in which the notch of the table plate is filled with the protrusion of the support plate. Even in this table state, the support plate and the rotating plate do not move relative to each other due to the two-point support of the rotation guide means and the stopper means.

Further, an engaging pin is provided at an appropriate position of the rotating plate so as to be retractable in the direction of the support plate, and the counter plate is placed on the second mounting edge and on the first mounting edge. In the case where the stopper means provided with the engaging hole for engaging the engaging pin at each corresponding position of the support plate in the above state is provided,
In both of the counter mode and the table mode, the engagement pin engages with the engagement hole to surely restrict the rotation of the rotating plate with respect to the support plate, and the operation is performed inside the rotating plate. It can be done from

Further, arc edges around the pivot point of the rotation guide means are formed at the end edges of the first mounting edge and the second mounting edge on the side opposite to the stop edge of the support plate. In this case, the rotating operation of the rotating plate and the counter plate with respect to the supporting plate is smooth.

Further, since the support plate is pivotally attached to the table plate by the rotary damper, a braking force acts on the sudden rotation of the support plate, so that there is no impact due to the rotation and it is safe.
Further, the rotary damper has a structure in which a large braking force is generated when the support plate is rotated backward and downward, and no braking is generated or a small braking force is generated when the support plate is rotated upward and frontward. By doing so, the support plate does not unexpectedly rotate in the counter mode, and the rotation of the support plate from the table mode to the counter mode is light.

The counter mode is maintained.

Next, from the state of the counter mode, holding the counter portion B, the support plates 6 and 6 are attached to the rotary dampers 9 and 9.
When it is rotated 180 degrees backward about the center, the state shown by the imaginary line in FIG. 3 is obtained. Then, when the counter plate 5 is lifted from the rear side in a state where the knob 30 of the stopper means D is pulled to release the engagement between the engagement pin 26 and the engagement hole 27, the rotary plate 7 is rotated by the rotation guide means C. The shaft 15 is rotated upward by 180 degrees and the counter plate 5 is placed on the first mounting edge 8 as shown in FIG. 4 and is joined flush with the rear end of the table plate 1. After that, the knob 30 of the stopper means D is pushed in to engage the engagement pin 26 with the engagement hole 28 to realize the table mode. In this state, similarly to the above, the rotation guide means C and the stopper means D support and fix the rotating plate 7 to the support plate 6 at two points, thereby reliably restricting the rearward movement of the counter plate 5. .

At the respective edge portions of the first mounting edge 8 and the second mounting edge 12 on the side opposite to 1, the pivot point of the rotation guide means C (the shaft 15
Since the circular arc edges 8a and 12a are formed around the center of the counter plate 5, the counter plate 5 can be smoothly rotated when the counter mode is changed to the table mode. In addition, the dimensional relationship such that a part of the arc edges 8a, 12a continuous with the linear portions of the first mounting edge 8 and the second mounting edge 12 contact the lower surface of the end portions 14, 14 of the counter plate 5, and By setting the curvature, the end portions 14, 14 of the counter plate 5 have the arc edges 8a, 12 immediately before the change to both modes.
It comes into sliding contact with a, and by this braking action, the counter plate 5
It is also possible to decelerate the rotation of to prevent abrupt movement.

On the other hand, the table mode shown in FIGS. 2 and 4 is changed to the counter mode shown in FIGS.
It is sufficient to reverse the above operation.

[0031]

The table with a counter of the present invention as described above has the following remarkable effects.

According to the first aspect, when the counter plate is placed on the second mounting edge while the first mounting edge of the support plate is placed on the table plate, the counter is placed above the rear portion of the table plate. In the counter mode in which the plate is positioned, the support plate is rotated 180 degrees downward while maintaining the positional relationship between the support plate and the counter plate from the counter mode, and the tongue of the support plate is brought into contact with the back surface of the table body. In this state, the rotary plate is rotated upward by 180 degrees with respect to the support plate about the pivot portion of the rotation guide means to mount the counter plate on the first mounting and supporting edge and the rear edge of the table plate. When joined together, a table mode in which the cutouts of the table plate are filled with the protrusions of the support plate can be obtained, and the mutual conversion in this mode can be easily and smoothly performed only by a rotating operation.

According to the second aspect, in the counter mode and the table mode, the rotating plate is fixed to the support plate by the two-point support by the rotation guide means and the stopper means. It does not move unexpectedly, and this state can be maintained extremely stable.

According to the third aspect, in both the counter mode and the table mode, the engagement pin engages with the engagement hole, and the rotation of the rotating plate with respect to the support plate can be reliably regulated. Moreover, since the operation can be performed from the inside of the rotating plate, it is easy.

According to the fourth aspect, the rotating operation of the rotating plate and the counter plate with respect to the supporting plate can be smoothly performed. In addition, by setting the dimensional relationship and the curvature so that a part of the arc edge that is continuous with the linear portion of the first mounting edge and the second mounting edge contacts the lower surface of the counter plate, change to both modes. Immediately before, the counter plate is slidably contacted with the circular arc edge, and this braking action can reduce the rotational movement of the counter plate.

According to the fifth aspect, since the braking force acts on the sudden rotation of the support plate and there is no impact due to the rotation, there is no fear of damage to the rotating member, and there is no finger stuffing or the like. Further, the rotary damper has a structure in which a large braking force is generated when the support plate is rotated backward and downward, and no braking is generated or a small braking force is generated when the support plate is rotated upward and forward. Therefore, the support plate does not rotate unexpectedly in the counter mode, and the rotation of the support plate from the table mode to the counter mode is light.
