Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used when a commercial container heating device for heating a cup or can of food or drink such as coffee, or an electric appliance such as a home television system is placed. The improvement of a turntable for mounting electric appliances.

[0002]

2. Description of the Related Art As a turntable for mounting electric appliances, those shown in FIGS. 6 and 7 have already been proposed.

The conventional turntable shown in FIG. 6 has a table 100 on which electric appliances are placed, a base unit 101 which rotatably supports the table 100,
And the relay power cord 102. The relay power cord 102 is the base unit 101.
The peripheral wall 101a of the base unit 101 through the inside and outside
The power output terminal 103 is attached to the upper surface of the table 100 through a hole 104 formed in the central portion of the table 100. This power output terminal 1
03 is connected to the plug 107 on the electric appliance 105 side to supply electric power to the electric appliance 105. In addition, the table 100 has a cylindrical shaft supporting portion 108 provided at the center thereof projected into a hole 109 on the base unit 101 to prevent displacement and blurring in the horizontal plane, and further, to prevent the base unit 101 from moving. While supporting the load by a plurality of rollers 110 fixed to the upper surface,
It can be rotated around 8.

In the conventional turntable shown in FIG. 7, the cord insertion hole 111 is formed on the upper surface of the base unit 101.
To connect the power output terminal 103 to the base unit 101.
To the space between the table and the table 100, and further the shaft support 1
After the relay power cord 102 is wound around the outer periphery of 08, the power output terminal 1 is passed through the cord insertion hole 112 formed at a position offset from the center of the table 100.
03 is guided to the upper surface of the table 100, but the other basic structure is similar to that of the turntable of FIG.

[0005]

As described above, all the conventional turntables have the relay power cord 10.
2 is led to the upper surface of the table 100 and connected to the cord 106 of the electric appliance 105.
When the height of the installation protrusion 113 provided on the table is low, the relay power cord 102 and the power output terminal 103 pulled out on the table 100, and the electric appliance 10
In some cases, the cord 106 and the plug 107 of No. 5 interfered with the lower surface of the electric appliance 105, making it difficult to stably mount the electric appliance 105. When a commercial container heating device or the like is placed as the electric appliance 105, the relay power cord 102 located on the lower surface of the electric appliance 105.
There is also a possibility that the cord 106 is heated and the coating of the cord is damaged.

Further, as in the conventional example shown in FIG. 6, in a structure in which only one central portion of the relay power cord 102 is fixed to the base unit 101 and the relay power cord 102 is fixed, electrification is performed. When the power output terminal 103 is erroneously pulled when the product 105 is replaced, etc., the fastening portion 114 of the base unit 101 may be damaged.

On the other hand, in the case of the conventional turntable as shown in FIG. 7, since the relay power cord 102 is wound around the shaft support 108 and then guided to the outside, the power output terminal 103 is erroneously provided. Even if it is pulled, it is unlikely that the fastening portion 114 will be damaged. However, when the relay power cord 102 is entangled with the shaft support 108 when the table 100 is rotated, the relay power cord 102 becomes tight between the shaft support 108 and the fastening portion 114, and the table 100 is suddenly braked. The electric appliances 105 on the table 100 may be displaced due to the impact, or the base unit 101 itself may rotate together with the table 100 due to the inertia of the table 100. In particular,
When a commercial container heating device or the like is placed on the table 100, there is a concern that food and drink may spill from the cup in the container heating device. Further, the shaft support portion 108 and the fastening portion 11
If the relay power cord 102 is tightly attached to the relay power cord 4, there is a possibility that the relay power cord 102 may have a problem such as disconnection.

[0008]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, to prevent the relay power cord from being an obstacle, and to prevent the relay power cord from being inadvertently damaged. To provide a turntable for mounting.

[0009]

According to the present invention, there is provided a table on which an electric appliance is placed, a base unit for rotatably supporting the table, and a relay fixed to the base unit by penetrating the base unit in and out. With a power cord for
A turntable for placing electrical appliances, in which the power output terminal of the relay power cord is guided to the surface of the table through the internal space of the base unit and the table, and the power input terminal is connected to the other end of the relay power cord. In order to achieve the above object, in particular, the power output terminal of the relay power cord is guided to the peripheral wall of the table via the center of rotation of the table and integrally fixed to the hole formed in the peripheral wall. It has a configuration characterized by

The power output terminal of the relay power cord is guided to the peripheral wall portion of the table through the internal space of the base unit and the table, and is fixed so as to be integrated with the peripheral wall portion. The power cord for use does not stick out. Therefore, even if the height of the installation protrusion on the appliance is low, or even if the appliance does not have the protrusion for installation, the relay power cord interferes with the bottom surface of the appliance. The electric appliances can be stably placed on the table without doing so.
In addition, as a result of avoiding contact between the relay power cord and electrical appliances, the relay power cord is heated by the electrical appliances and the cord is heated even when a commercial container heating device is placed on the table. The problem of damaging the coating of the is eliminated. Furthermore, since the plug on the side of the electric appliance is connected to the power output terminal fixed to the peripheral wall of the table, it seems that the cord of the electric appliance is accidentally pulled when the electric appliance is replaced. Even in such a case, tension does not act on the relay power cord itself, and there is no fear that the fastening portion between the base unit and the relay power cord is damaged. Also, since the relay power cord is guided to the peripheral wall of the table via the center of rotation of the table, it is possible to change the position of the power output terminal relative to the base unit by rotating the table. However, the relay power cord is not excessively stretched or loosened, and the problem that the relay power cord is entangled with the mechanism portion and suddenly brakes the rotation of the table is solved.
As a result, it is possible to prevent the electric appliances on the table from being displaced due to the inertial motion when the table is stopped, and the base unit itself rotating together with the table due to the inertia of the table.

Further, between the base unit and the table, rotation limit restricting means for restricting the rotation amount of the table with respect to the base unit may be provided.

By arranging the rotation limit regulating means to regulate the rotation amount of the table, excessive twisting of the relay power cord is prevented, and the substantial durability of the relay power cord is significantly improved.

This rotation limit regulating means can be constituted by a first engaging piece fixed to the base unit side and a second engaging piece fixed to the table side. At that time, at least one of the engaging pieces is formed of a flexible elastic member, and one of the engaging pieces is formed of a concave member that opens in the rotation direction of the table, and the other engaging piece is formed. It is desirable that the piece is formed of a convex member that can be fitted into the opening of the concave member, and that the tip of the opening of the concave member is slightly smaller than the outer diameter of the convex member. More specifically, a case where only the first engaging piece on the base unit side is formed by a soft elastic member, a case where only the second engaging piece on the table side is formed by a soft elastic member, and In some cases, both the first engagement piece on the base unit side and the second engagement piece on the table side are formed by flexible elastic members. In addition, a concave member that opens in the rotation direction of the table is attached to the base unit side to form a first engaging piece, and a convex member that can be internally fitted in the opening of the concave member is attached to the table side. And a convex member that can be fitted in the opening of the concave member is attached to the base unit side to form the first engaging piece, and the concave member that opens in the rotation direction of the table is used. It may be attached to the table side and used as the second engaging piece.

In the case of applying such a structure, when the table is rotated beyond the rotation limit, the second engaging piece fixedly mounted on the table rotates and moves integrally with the table. The engaging piece of butt against the first engaging piece on the base unit side. Since the tip of the opening of the engaging piece made of the concave member is smaller in diameter than the outer diameter of the engaging piece made of the convex member, the second engaging piece collides with the first engaging piece. When
Either one or both of the first engaging piece and the second engaging piece elastically deforms in a direction orthogonal to the rotation direction of the table, and the second force is generated by the normal force due to the elastic return force and the mutual friction. A braking force is generated in the direction in which the rotational movement of the engaging piece is stopped, and the moving speed of the second engaging piece, that is, the rotational moving speed of the table is gradually attenuated. In addition, when the angular velocity of the table is increased by placing a heavy electrical appliance on the table or rotating the table quickly, that is, only the normal force due to the elastic return force and the braking force due to mutual friction described above are used. In the case where the rotation speed of the table cannot be sufficiently attenuated, after the engaging piece made of the convex member is inserted into the opening of the engaging piece made of the concave member, the inner surface of the concave member and the convex member are inserted. There is a possibility of strong collision with the outer periphery of the. In such a case, one or both of the first engagement piece and the second engagement piece elastically deforms in the same direction as the rotation direction of the table to weaken the impact when the table is stopped. As a result of preventing the sudden stop of the table in this way, the problems that the electric appliances on the table are displaced due to the inertial motion when the table is stopped, and the base unit itself rotates with the table are solved. . In addition, the table can be stopped accurately at a predetermined specific rotation position.

When this electric appliance mounting turntable is used as a means for installing a container heating device for business use, that is, an electrification for face-to-face selling with a customer by a first-in first-out method with a counter or the like sandwiched between them. When used as a means for installing the product, one of the engaging pieces is arranged at two right angle intervals at two locations on the circumference with the center of rotation of the table as a reference, and the other engaging piece is attached to the table. It is desirable to dispose it in one place on the same circumference as the above with the center of rotation as a reference.

By applying such a structure, the table is surely stopped at each of the selling position where the opening / closing door of the container heating device or the like is directed to the outside of the counter and the product supply position where the opening / closing door is directed to the inside of the counter. It becomes possible for the customer to take out the product and the seller to supply the product. Further, at each table stop position, the opening of the recessed member whose diameter is reduced reliably holds the convex member, so that the convex member does not come out of the opening of the concave member by a slight impact, and It is possible to stably hold the stationary state and perform smooth product taking-out operation and product replenishing operation.

Further, in addition to the above-mentioned respective constitutions, a bobbin for winding a cord of an electric appliance placed on a table is provided, and a bobbin locking stay for holding the bobbin in a easily detachable state is provided. It may be arranged on the outer periphery of the table.

It is possible to wind the redundant part of the cord of the electric appliance around the bobbin and place it on the outer peripheral portion of the table, and the problem that the cord of the electric appliance itself becomes an obstacle is solved. In addition, since the bobbin locking stay holds the bobbin in a state where it can be easily attached and detached, if the electric appliance is accidentally caught on the bobbin when the electric appliance is replaced, the bobbin will automatically The impact can be relieved by being disengaged from the bobbin locking stay, and damage to the bobbin and the mounting portion of the bobbin locking stay can be avoided.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the appearance of an electric appliance mounting turntable 1 according to an embodiment of the present invention. As shown in FIG. 1, an electric appliance mounting turntable 1 of this embodiment includes a table 2 for mounting electric appliances, a base unit 3 for rotatably supporting the table 2, and a base unit 3. The relay unit includes a relay power cord 4 penetrating in and out and fixed to the base unit 3.

Next, the structures of the table 2 and the base unit 3 will be described in detail with reference to FIG.

As shown in FIG. 2 (a), the table 2 has a substantially rectangular shape as a whole, and is a top plate 2a on which an electric appliance is placed, and the table 2a is provided downward from the outer peripheral portion of the top plate 2a. It is integrally provided with a peripheral wall portion 2b that extends toward the outside. Also, the top plate 2
A shaft support portion 5 protruding downward from the back surface of the top plate 2a is provided integrally with the top plate 2a at the center of a.

The shape of the shaft support 5 is shown in FIG. The shaft supporting portion 5 is formed in a cylindrical shape as a whole, and the slits 6 formed at intervals of 60 degrees in the circumferential direction along the cylinder,
At least at the tip of the shaft support portion 5, this cylindrical portion is divided into six tongue pieces 7. Of these tongue pieces 7, wedge-shaped engaging projections 7a are integrally formed on the outer peripheral ends of the three tongue pieces 7 arranged at positions where the phases differ by 120 degrees. Further, one of the remaining tongue pieces 7 is formed with a cutout portion 8 for passing the relay power cord 4.

On the lower surface side of the top plate 2a, as shown in FIG.
As shown in (a), eight pairs of rollers 9 are rotatably supported by a shaft and are attached at intervals of 45 degrees in the circumferential direction along the circumference centered on the disposition position of the shaft support portion 5. Has been.
The support shafts of the rollers 9 are all orthogonal to the above-mentioned circumference, and therefore the rotation direction of each roller 9 is completely coincident with the rotation direction of the table 2 around the shaft support 5.

Further, on the lower surface side of the top plate 2a, at a position slightly closer to the center from the roller 9, there is integrally formed a convex member 10 serving as a second engaging piece which constitutes a part of the rotation limit regulating means. Is stuck to. The convex member 10 is a columnar protrusion formed of a flexible elastic material such as rubber.

On the other hand, the base unit 3 has a disc shape as a whole as shown in FIG. 2 (b), and includes a top plate 3a which is a traveling surface of the roller 9 and an outer peripheral portion of the top plate 3a. The peripheral wall portion 3b extending downward is integrally provided.
Then, at the central portion of the top plate 3a, the shaft support portion 5 of the table 2 is
A hole 11 is provided for penetrating the tip of the and fixing it rotatably.

Further, the upper surface of the top plate 3a is provided with a first engagement which forms a part of the rotation limit restricting means at intervals of 2 right angles in the circumferential direction along the circumference centered on the hole 11. 2
One concave member 12 is fixed. The distance from the center of the hole 11 to the center of each concave member 12 is the same as the distance from the center of the shaft supporting portion 5 to the center of the convex member 10 described above, and therefore, the concave member serving as the first engaging piece. Both 12 and the convex member 10 serving as the second engaging piece are present on the same circumference with the center of rotation of the table 2 as a reference.

The concave member 12 is a block-shaped member made of ABS resin or the like, and has an opening 13 on one surface which opens in the rotational direction of the table 2, that is, in the circumferential direction. This opening 13 is, as shown in FIG.
It is composed of an opening main body 13a having an inner diameter that is substantially the same as the outer diameter of the convex member 10 formed in a cylindrical shape, and an opening tip 13b slightly reduced in diameter as compared with the outer diameter of the convex member 10. ing.

The bobbin 14 for winding the redundant cord of the electric appliance 105 placed on the table 2 is shown in FIG.
As shown in (a), a bobbin engaging member for holding a bobbin 14 on which the cord of the electric appliance 105 is wound is formed on one side of the outer peripheral portion of the table 2 and is formed of a flat plate having flanges at both ends. The stop stay 15 is fixed.

The bobbin locking stay 15 is formed by a bottom plate 15a for supporting the load of the bobbin 14 and a side plate 15b for preventing the bobbin 14 from falling off. Since the side plate 15b is attached to the outside in a tilted posture, the bobbin 14 can be held securely even when the bobbin 14 has a substantially large outer diameter due to the cord wound around the bobbin 14. You can

On the other hand, if the electric appliance 105 is accidentally caught on the bobbin 14 when the electric appliance 105 is replaced, etc., the bobbin 14 is easily moved to the outside by moving along the slope of the side plate 15b. Because it will fall to
The bobbin locking stay 15 and the bobbin 14 themselves can be effectively prevented from being damaged.

Next, the overall assembly structure of the electric appliance mounting turntable 1 will be described with reference to the sectional view of FIG.

The relay power cord 4 penetrates a part of the peripheral wall portion 3b of the base unit 3, and its substantially central portion is fixed to the base unit 3 via a fixing portion 114 such as a rubber bush. The power output terminal 16 provided at one end of the relay power cord 4 is guided to the hole 11 provided in the top plate 3 a of the base unit 3 via the internal space of the base unit 3. The engaging projection 7 of the tongue piece 7 is fitted in the hole 11.
via the inside of the shaft support portion 5 which is provided with a stopper, that is, the center of rotation of the table 2, through the notch 8 formed in the outer peripheral portion of the shaft support portion 5 into the internal space of the table 2, Furthermore, it is guided to the peripheral wall portion 2b of the table 2 and integrally fixed to the hole 17 formed in the peripheral wall portion 2b.
As shown in FIG. 1, the mounting position of the power output terminal 16 on the peripheral wall portion 2b is one side on the same side as the bobbin locking stay 15 described above. The shape and function of the power output terminal 16 are substantially the same as those of a household power tap or the like.

As shown in FIG. 4, the relay power cord 4
Since the rear side of the concave member 12 is passed through in the internal space of the table 2, even when the table 2 is rotated, it is used as a relay between the opening 13 of the concave member 12 and the convex member 10. The power cord 4 does not break in.

Further, since each roller 9 is attached to the table 2 side in the same manner as the power output terminal 16, the portion of the relay power cord 4 existing between the shaft support portion 5 and the power output terminal 16 and each roller 9 are connected. The relative positional relationship with the roller 9 is always constant regardless of the rotational position of the table 2 with respect to the base unit 3. Therefore, even if the table 2 is rotated, the relay power cord 4 does not interfere with the roller 9.
(If the relay power cord is guided to the peripheral wall of the table with the structure in which the roller is attached to the base unit side as in the conventional example of FIG. 6 and FIG. 7, the relay power cord acts on the roller when the table is rotated. There is a problem of getting entangled.)

Moreover, the relay power cord 4 is attached to the table 2
Since it is configured to be guided to the peripheral wall portion 2b of the table 2 via the center of rotation of the table 2, the relay power cord 4 required to reach the peripheral wall portion 2b from the fastening portion 114 via the shaft support portion 5 The length is always constant regardless of the rotational position of the table 2 with respect to the base unit 3. Therefore, even when the table 2 is rotated to change the relative position of the power output terminal 16 with respect to the base unit 3, the relay power cord 4 may be pulled and tightened or entangled with the mechanical portion. There is no. (As in the conventional example of FIG. 7, in the structure in which a cord insertion hole is formed in each of the base unit and the table at a position offset from the center of rotation of the table and the relay power cord is routed, the rotation of the table causes (Since the distance between the cord insertion hole and the cord insertion hole on the table side changes, there is a problem that the relay power cord may become tight or loose.)

Next, a method for installing and using the electric appliance mounting turntable 1 of this embodiment will be briefly described.

First, the table 2 is rotated up to one of the rotation limits with respect to the base unit 3 to fit the convex member 10 on the table 2 side into the concave member 12 on the base unit 3 side, The relative rotational position of the table 2 with respect to the base unit 3 is specified. The table 2 is rotatable with respect to the base unit 3 within a range of 2 right angles from the initial position.

Therefore, when the electric appliance 105 such as a container heating device for business use is installed, after the relative rotational position of the table 2 with respect to the base unit 3 is specified as described above, for example, as shown in FIG. Then, the turntable 1 is installed on the counter so that the bobbin locking stay 15 comes inside the counter, and the electric appliance 105 is placed on the table 2 with the opening / closing door of the container heating device facing the outside of the counter. Place it.

When the cord 106 of the electric appliance 105 is redundant, the extra portion of the cord 106 is wound around the bobbin 14, and the bobbin 14 is placed on the bobbin locking stay 15. Further, the plug 10 provided at the tip of the cord 106
7 is connected to the power output terminal 16 on the table 2 side, and the power input terminal 18 provided at the tip of the relay power cord 4 of the electric appliance mounting turntable 1 is connected to an outlet in the store in advance.

Here, when a cup or can of food or drink is put in the container heating device, the table 2 is grasped and
From the state like the above, rotate the table 2 by 2 right angles,
Relative rotation of the table 2 with respect to the base unit 3 so that the convex member 10 on the table 2 side is fitted to the other concave member 12 on the base unit 3 side so that the opening / closing door of the container heating device faces the inside of the counter. Identify the location. This is a state in which the table 2 is rotated by two right angles from the initial position.

The phenomenon when the convex member 10 on the table 2 side contacts the concave member 12 on the base unit 3 side by the rotation of the table 2 will be described with reference to FIGS. 5 (b) to 5 (e).

First, when the table 2 is slightly rotated from the initial position by two right angles, as shown in FIG. 5B, the outer peripheral portion of the convex member 10 on the table 2 side is the concave member 12 on the base unit 3 side. It abuts the tip 13b of the opening. Since the opening end 13b of the concave member 12 has a smaller diameter than the outer diameter of the convex member 10, when the convex member 10 collides with the concave member 12, it is shown in FIG. As described above, the convex member 10 is pressed from both sides and elastically deforms in the direction orthogonal to the moving direction, and the elastic restoring force causes a vertical reaction force between the convex member 10 and the opening end 13b and friction between the two. As a result, a braking force is generated in a direction in which the movement of the convex member 10 is stopped, and the moving speed of the convex member 10, that is, the rotational moving speed of the table 2 is gradually attenuated.

When the convex member 10 collides with the concave member 12 with a weak force, that is, when the rotation speed of the table 2 is low, the contact between the convex member 10 and the opening end 13b is started. It is possible to completely stop the rotation of the table 2 by the above-mentioned braking force that acts from the time until the convex member 10 completely penetrates into the opening body 13a of the concave member 12, and the opening of the concave member 12 The convex member 10 that has passed through the tip 13b of the portion is stored in the opening body 13a of the concave member 12 as it is in the state as shown in FIG.

However, when the rotation speed of the table 2 is high and the convex member 10 collides with the concave member 12 with a strong force, it becomes difficult to stop the rotation of the table 2 only by the braking force described above. There are cases. In such a case, as shown in FIG. 5E, after the convex member 10 is inserted into the opening body 13 a of the concave member 12, the outer peripheral portion of the convex member 10 is further covered with the concave member 12. When the convex member 10 strongly abuts against the inner surface of the opening main body 13a and is elastically deformed and compressed in the same direction as the moving direction as shown in FIG. 5D, the rotation of the table 2 is stopped. Weaken the shock of time. After that, the convex member 10 elastically returns to the initial shape and is housed in the opening body 13a of the concave member 12 in the state as shown in FIG.

The sudden stop of the rotation of the table 2 is prevented, and the inertial force acting on the electric appliance 105 on the table 2 when the table 2 is stopped is relaxed.
Problems such as positional deviation of the upper appliance 105 and rotation of the base unit 3 of the appliance mounting turntable 1 together with the table 2 are solved.

In this way, the table 2 is rotated, the opening / closing door of the container heating device is directed to the inside of the counter, and then the opening / closing door of the container heating device is opened to place a cup or can of food or drink in the container heating device. Will be placed in.

During this time, the convex member 10 on the table 2 side is in the state as shown in FIG.
Since it is held in a, the table 2 does not inadvertently rotate even if a slight shock is given to the container heating device or the table 2, and a predetermined specific rotation position,
That is, it is possible to smoothly perform the operation of the opening / closing door of the container heating device and the replenishment operation of the product while maintaining the state in which the opening / closing door of the container heating device is directed toward you.

When the product replenishing operation is completed, the reverse direction table 2 is rotated by 2 right angles to return to the above-mentioned initial position, and the opening / closing door of the container heating device is outside the counter, that is, the customer. Turn to where you are. Similar to the above, the convex member 10 on the table 2 side and the base unit 3
Since the impact when the rotation of the table 2 is stopped can be mitigated by the fitting relationship with the concave member 12 on the side, even if a cup or the like is arranged in the container heating device, the spilling of food and drink is effective. Can be prevented. Further, since the convex member 10 on the table 2 side is held by the other concave member 12 with the opening / closing door of the container heating device facing the outside of the counter, like the above, inadvertent rotation of the table 2 is prevented. In this state, products such as cups and cans can be smoothly taken out from the container heating device.

Since the rotation limit of the table 2 with respect to the base unit 3 is limited to the range of 2 right angles, even if the table 2 has to be frequently rotated for the replenishment of goods, it is for relaying. There is no risk of the power cord 4 being excessively twisted and broken.

Moreover, since the power output terminal 16 for inserting the plug 107 of the electric appliance 105 is integrally fixed to the outer peripheral portion of the table 2, the relay power cord 4 interferes with the lower surface of the electric appliance 105. Therefore, even an electric appliance having a low height of the installation protrusion 113 or an electric appliance having no installation protrusion 113 can be stably placed on the table 2.

Since the excess portion of the cord 106 of the electric appliance 105 can be wound around the bobbin 14 and separated from the electric appliance 105, it is as if a container heating device for business use is placed on the table 2. Even in such a case, the problem that the relay power cord 4 or the cord 106 is heated by the electric appliance and the coating is damaged does not occur.

Since the power output terminal 16 is integrally attached to the outer peripheral portion of the table 2, the relay power cord 4 is provided.
There is no problem of being inadvertently pulled from the outside,
The relay power cord 4 is not damaged and the fixing portion 114 for fixing the relay power cord 4 is not damaged.

As described above, as one embodiment, the two concave members 12 are fixed to the base unit 3 side as the first engaging pieces, while the one convex member 10 is the second engaging piece on the table 2 side. Although an example in which only the second engaging piece formed of the convex member 10 is fixed to the flexible elastic member is described above, the materials and shapes of the first engaging piece and the second engaging piece are described. The following combinations are possible.

First, regarding the materials of the first engaging piece and the second engaging piece, in the above-mentioned embodiment, contrary to the above, the base unit 3 which functions as the first engaging piece.
It is possible to form only the two concave members 12 on the side from a flexible elastic member and to form one convex member 10 on the table 2 side that functions as the second engaging piece from ABS resin or the like. In this case, the concave member 12 on the base unit 3 side is elastically deformed to absorb the shock when the table 2 is stopped. In addition, the two concave members 12 on the base unit 3 side that function as the first engaging pieces and the one convex member 10 on the table 2 side that functions as the second engaging piece are both formed of flexible elastic members. May be. In this case, the concave member 12 on the base unit 3 side and the convex member 1 on the table 2 side
Both of 0 elastically deform to absorb the shock when the table 2 is stopped.

Further, regarding the shapes of the first engaging piece and the second engaging piece, contrary to the above-mentioned embodiment, two concave members 12 are provided on the lower surface of the table 2 as the second engaging piece. Mounted on the upper surface of the base unit 3 as one convex member 1
It is possible to attach 0 as the first engagement piece.
Also in this case, regarding each material, one convex member 1 on the side of the base unit 3 that functions as the first engaging piece is used.
Only 0 is formed of a flexible elastic member, and the two concave members 12 on the table 2 side that function as the second engaging piece are formed of ABS.
It is made of resin or the like, and only the two concave members 12 on the table 2 side that function as the second engagement piece are formed of a flexible elastic member, and the base unit 3 side that functions as the first engagement piece. Forming one convex member 10 of ABS resin or the like, and further, one convex member 10 on the base unit 3 side that functions as the first engaging piece and a table that functions as the second engaging piece. It is possible to form the two concave members 12 on the two sides together from a flexible elastic member.

The concave member functioning as the first engaging piece or the second engaging piece is shown in FIG. 5 (f) in addition to the concave member 12 shown in FIG. 5 (a). A concave member 12 'having such a shape can be used. This concave member 1
Reference numeral 2'includes an opening tip 13b 'and an opening body 13a' that gradually taper from the outside to the inside, and the maximum width of the opening tip 13b 'is equal to or greater than that of the convex member 10. The diameter is slightly reduced. When such a concave member 12 is applied, the convex member 10 slides on the tip 13b 'of the opening over a relatively long distance in the process of stopping the rotation of the table 2, so that the rotation of the table 2 is stopped. It is possible to apply a braking force for operating for a long time, which is suitable for mounting an electric appliance 105 having a large weight, that is, inertia.

In the above-mentioned embodiment, the example in which the table 2 is rotated within the range of 2 right angles has been described. However, if the mounting intervals of the two concave members 12 are changed, the table 2 can be used according to its use.
It is possible to freely adjust the rotation limit of the table 2 within a range of zero or more and less than four right angles.

Generally, when the allowable rotation angle is large, the angular momentum at the time of rotation of the table 2 also increases. Therefore, when the allowable rotation angle is large, the concave member 12 'as shown in FIG. 5 (f) is preferable. Further, when the allowable rotation angle is small, the concave member 12 as shown in FIG. 5A is sufficient.

In the turntable for mounting electric appliances of the present invention, the power output terminal of the relay power cord is guided to the peripheral wall portion of the table via the center of rotation of the table, and the hole formed in this peripheral wall portion. Since the relay power cord does not stick out from the upper surface of the table because it is configured to be integrally fixed to the table, if the height of the installation protrusion provided on the appliance is low, or Even if the installation projection is not provided on the appliance, the appliance can be stably placed on the table without the relay power cord interfering with the lower surface of the appliance. In addition, as a result of avoiding contact between the relay power cord and electrical appliances, the relay power cord is heated by the electrical appliance and the cord is heated even if a commercial container heating device is placed on the table. The problem that the coating is damaged does not occur.
Furthermore, since the plug on the side of the electric appliance is connected to the power output terminal fixed to the peripheral wall of the table, it seems that the cord of the electric appliance is accidentally pulled when the electric appliances are replaced. Even in such a case, tension does not act on the relay power cord itself, and there is no fear that the fastening portion between the base unit and the relay power cord is damaged.
In addition, since the relay power cord is guided to the peripheral wall of the table via the center of rotation of the table, it is possible to change the position of the power output terminal relative to the base unit by rotating the table. However, the relay power cord is not excessively stretched or loosened, and the problem that the relay power cord is entangled with the mechanical portion and suddenly brakes the rotation of the table is solved. As a result, it is possible to prevent the electric appliances on the table from being displaced due to the inertial motion when the table is stopped, and the base unit itself rotating together with the table due to the inertia of the table.

Further, since the rotation limit regulating means for regulating the rotation amount of the table with respect to the base unit is provided between the base unit and the table, excessive twisting of the relay power cord is prevented, and the relay power cord is prevented. The substantial durability of is greatly improved.

Particularly, the rotation limit regulating means is constituted by the concave member and the convex member which are opened in the rotation direction of the table, and at least one member is formed of a flexible elastic member, whereby the concave member and the convex member are formed. Due to the elasticity and friction with the members, it is possible to slow down the deceleration operation when the positioning of the table is stopped, and the inertial motion when the table is stopped causes the electrical appliances on the table to shift in position and the base unit itself to move together with the table. It becomes possible to effectively prevent the problem of rotation.

Further, by restricting the rotation limit of the table to 2 right angles by the arrangement of the concave member and the convex member, the sales position with the opening / closing door of electric appliances such as container heating devices facing the outside of the counter and the inside of the counter. It is possible to reliably stop the table at each of the product replenishment positions toward the side and perform the product retrieving operation on the customer side and the product replenishing operation by the seller.

Further, since the bobbin for winding the cord of the electric appliance placed on the table and the bobbin locking stay for holding the bobbin in the easily detachable state are provided on the table, It becomes possible to wind the redundant part of the cord of the electric appliance around the bobbin and place it on the outer peripheral portion of the table, and the problem that the cord of the electric appliance itself becomes an obstacle is solved. In addition, since the bobbin locking stay holds the bobbin in a state where it can be easily attached and detached, if the electric appliance is accidentally caught on the bobbin when the electric appliance is replaced, the bobbin will automatically The impact can be relieved by being disengaged from the bobbin locking stay, and damage to the bobbin and the mounting portion of the bobbin locking stay can be avoided.
