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 case to smoothly and easily perform the mutual change between the counter mode and the table mode, and the state of the table mode. In addition to the fact that the support plate of the counter plate does not remain on the table plate, a table with a counter that can maintain the states of both modes extremely stably is provided.

[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 protruding portion pivotally attached by a rotary damper is provided so as to be rotatable by 180 degrees, and a side adjacent to the protruding portion serves as a stop edge to the back surface of the table body, and a side facing the first mounting support edge is formed. No second support,
A pair of support plates whose inner surfaces are connected to each other by a connecting plate; a counter plate having a rotating plate on both sides of the lower surface, the rotary plates protruding so as to be located inside the support plate with the end portions left behind; A linear guide groove is formed at a position equidistant between the first mounting edge and the second mounting edge and on the side opposite to the stop edge and parallel to both mounting edges. The plate is provided with a shaft body that is slidably engaged with the guide groove, and the shaft body moves in the guide groove.
A table with a counter is constituted by: guide means that allows the counter plate to move between a state of being placed on the second mounting edge and a state of being placed on the first mounting edge.

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. It is a preferred embodiment to provide a stopper means provided with an engaging hole for engaging the engaging pin at each corresponding position of the support plate in the placed state.

Further, with the stop edge of the support plate abutting against the back surface of the table body, the counter plate placed on the first mounting edge and the counter plate and the table plate joined together, the table plate It is also a preferred embodiment that the rotating plate is provided with an overhanging portion that abuts the lower edge of the rotating plate.

At both end portions of the lower surface of the counter plate, there are provided restriction pins that project downward by their own weight only when the lower surface of the counter plate faces downward.
It is more preferable to provide a movement regulation means having a regulation hole for receiving the regulation pin only on the second mounting edge of the support plate.

[0011]

In the table with a counter of the present invention having the above contents, 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. When the shaft body protruding from the rotating plate of the counter plate is positioned at one end (rear end) of the guide groove of the support plate, the counter plate is positioned above the rear part of the table plate. In this state, since the guide groove is horizontal, the counter plate does not unexpectedly lift up with respect to the support plate. In addition, while maintaining the positional relationship between the support plate and the counter plate from the counter mode, the support plate is rotated 180 degrees while applying braking with the rotary damper, and the toe edge of the support plate is brought into contact with the back surface of the table body. When the shaft body is slid along the guide groove to the other end, the counter plate moves rearward along the second mounting edge, and then the counter plate is rotated upward by 180 degrees about the shaft body. By making the shaft parallel to the first mounting and supporting edge and sliding the shaft along the guide groove to the center thereof, the counter plate is placed on the first mounting and supporting edge and flush with the rear edge of the table plate. The table is in a state in which the notches of the table plate are joined together and the protrusions of the support plate are filled. Even in this table state, since the guide groove is horizontal, the counter plate does not abruptly lift up with respect to the support plate. On the other hand, the change from the table mode to the counter mode is realized by reversing the above operation. The rotary damper has such a structure that 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. If adopted, the support plate does not rotate unintentionally in the counter mode, and the rotation of the support plate from the table mode to the counter mode is light.

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 holes for engaging the engaging pins at the corresponding positions of the support plate in the placed state is provided, the engaging pins are provided in both the counter mode and the table mode. By engaging with the engaging hole, the rotation and movement of the rotating plate with respect to the support plate are reliably regulated.

Further, with the stop edge of the support plate abutting against the back surface of the table body, the counter plate placed on the first mounting edge, and the counter plate and the table plate joined together, the table plate By extending the overhanging portion that abuts the lower edge of the rotating plate, the lifting and rattling of the counter plate in the table mode can be reliably regulated.

At both end portions of the lower surface of the counter plate, restriction pins are provided which project downward due to their own weight only when the lower surface of the counter plate faces downward.
When the movement regulating means is provided with the regulation hole for receiving the regulation pin only on the second mounting / supporting edge of the support plate, in the counter mode, the regulation pin projects downward due to its own weight to the regulation hole of the support plate. Since it is inserted, the counter plate is restricted from moving forward along the second mounting support edge, and when used together with the above-mentioned stopper means, even if the operation of the stopper means is forgotten, it is automatically It is safe because it is temporarily fixed. On the other hand, when the support plate is rotated rearward and downward so that the lower surface of the counter plate faces upward, the regulation pin is retracted into the counter plate by its own weight, so that the counter plate moves backward along the second mounting edge. It is possible to move.

It is located. In this state, the knob 30 of the stopper means is pushed in to engage the engagement pin 26 with the engagement hole 27, thereby restricting the movement of the shaft body 15 in the guide groove 13. Since the second mounting support edge 12 and the guide groove 13 are parallel to each other, the counter plate 5 rotates about the shaft 15 and the counter plate 5 supports the support plate 6.
It is impossible in principle to lift up against. Further, in this state, since the regulation pin 33 is inserted into the regulation hole 34 by its own weight, even if the operator forgets to operate the stopper means, the counter plate 5 moves along the second mounting support edge 12. There is nothing to do.
Further, since the support plate 6 is pivotally attached to the table plate 1 by the rotary damper 9 having a large braking force against the downward rotation of the back, the counter portion B does not rotate unexpectedly and is extremely stable. The counter mode is maintained.

Next, from the state of the counter mode, the knob 30 of the stopper means is pulled out to engage the engaging pin 26 and the engaging hole 2.
In a state where the engagement with 7 is released, the counter plates B are held and the support plates 6 and 6 are rotated 180 degrees rearward about the rotary dampers 9 and 9 to obtain the state of FIG. In this state, the regulation pin 33 is retracted into the recess 35 by its own weight, so that the counter plate 5 can be moved rearward as shown by the imaginary line, and the shaft body 15 moves in the guide groove 13 to the end b. When it reaches, the counter plate 5 is centered around the shaft body 15.
Is rotated forward and the first mounting edge 8 of the support plate 6 and the counter plate 5 are parallel to each other, and then the counter plate 5 is moved in the guide groove 13 as shown in FIG. By moving to the front, it moves until it joins the table plate 1 while sliding on the first mounting and supporting edge 8, and becomes the illustrated table mode. Then, by pushing the knob 30 of the stopper means to engage the engaging pin 26 with the engaging hole 28,
The backward movement of the counter plate 5 is surely regulated, and when the counter plate 5 is unexpectedly moved and used as a table, there is no fear that the article placed on the counter plate 5 falls or falls. Of. In this state, the rotating plate 7
The overhanging portion 31 extended to contact the lower surface of the rear edge portion of the table plate 1 to restrict the lifting of the counter plate 5, and the lower surface of the central portion of the counter plate 5 on the joining side has the support piece 17.
The counter plate 5 is restrained from bending downward.

In this table mode, as shown in FIG. 5, the upper surfaces of the table plate 1 and the counter plate 5 are joined flush with each other, and the rear edge of the table plate 1 is a slanted surface 38 which is inclined upward, and By making the front edge of the plate 5 a slanted surface 39 which is inclined downward, both slanted surfaces 38, 39 can be joined together and the downward deformation of the counter plate 5 can be restricted over the entire length. Further, in this embodiment, the support plate 6
Is located below the counter plate 5 without remaining on the table plate 1 and fills the notches 4 of the table plate 1 with the projections 10 of the support plate 6, so that the upper surface has a flat depth width. A wide table can be constructed.

On the other hand, from the table shown in FIG. 5 to FIG.
To change to the counter mode shown in (3), the above operation may be reversed.

[0031]

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

According to the first aspect, the counter plate is mounted on the second mounting edge while the first mounting edge of the supporting plate is mounted on the table plate, and the counter plate is mounted on the rotating plate of the counter plate. When the protruding shaft body is positioned at one end (rear end) of the guide groove of the support plate, a counter mode in which the counter plate is positioned above the rear part of the table plate can be provided, and the guide groove is horizontal. , The counter plate does not suddenly lift up against the support plate, and the support plate easily rotates backward due to the braking force of the rotary damper, so that the first mounting edge does not separate from the table plate. It can be kept extremely stable. Also, in the state where the counter mode is changed to the table mode, the counter plate is placed on the first mounting and supporting edge and is joined flush with the rear edge of the table plate, the guide groove is horizontal as described above, The counter plate is stable because it does not suddenly lift up against the support plate.

According to the second aspect, in both the counter mode and the table mode, the engagement pin engages with the engagement hole to reliably regulate the rotation and movement of the rotating plate with respect to the support plate. You can

According to the third aspect, lifting and rattling of the counter plate in the table mode can be reliably controlled.

According to the fourth aspect, in the counter mode, since the regulation pin projects downward by its own weight and is inserted into the regulation hole of the support plate, the counter plate is prevented from moving forward along the second mounting edge. It can be regulated, and when it is used together with the above-mentioned stopper means, it is safe because the temporary fixing is automatically performed even if the operation of the stopper means is forgotten.
