DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, the mounting of counters in a system kitchen to a cabinet, and more particularly to a structure and a method for matching the heights of two counters in a portion where the ends of the counters are arranged to abut each other. About.

[0002]

2. Description of the Related Art In a system kitchen, if the plane layout is L-shaped, for example, the ends of two counters are arranged at the corners of the kitchen, and the lower surfaces of the ends of these counters are connected by a connector. The structure is generally. At the same time as the connection of the counters, a mechanism for adjusting the height of the counters is provided in the connecting tool, so that the two counters are assembled at the same level.

As a connecting tool for connecting and adjusting the level of such a counter, for example, there is a connecting tool proposed and filed by the present applicant and published as Japanese Patent Application Laid-Open No. 58-116320. In this method, connecting metal fittings are fixed to the lower surface of the counter in pairs, fastening bolts are provided in the direction that cuts across the boundary of the counter, and further inserted vertically into the part where the connecting metal fittings overlap each other vertically. It has a level adjustment screw.

[0004] With such a connection fitting, it is possible to adjust the height of the counter by rotating the level adjustment screw at the same time as connecting the counters with each other by fastening bolts.

[0005]

In the above-mentioned publication, a screw is used for attaching the connecting member to the lower surface of the counter. In this case, there is no hindrance to the work of screwing the connecting member to the counter before assembling the counter to the cabinet. However, if the positions of the couplings are not proper after being assembled to the cabinet, or if there is a misalignment between the couplings that abut each other, the screws are pulled out, the positions are changed, and then the screws are screwed again.

[0006] Such a work of correcting the position of the connecting member requires a large amount of work to remove the counter from the cabinet. Therefore, it is necessary for an operator to sink into the cabinet to remove and screw in the screw. For this reason, the operation is very difficult, and particularly the operation on the connecting tool on the back side of the cabinet becomes considerably complicated.

In addition, since the connecting member receives the load at the end of the two counters, the load for the level adjusting screw is large. For this reason, in the above-mentioned publication, two screws are arranged in the depth direction of the counter, and the level of the counter is adjusted by a pair of connecting tools according to the screwing amount of these screws.

However, since a plurality of couplers themselves are arranged in the depth direction of the counter, it takes time to adjust these screws, and there is a problem in workability.

As described above, with the conventional counter height adjusting structure, it is difficult to repeat the work for correcting the position of the connector, and there is also a problem in the overall workability.

The problem to be solved in the present invention is to make the operation for adjusting the height of the counters easier and more reliable.

[0011]

According to the present invention, there is provided a height adjusting structure in which the joining ends of a pair of counters are arranged in a plane by abutting each other and the levels of the counters are made to coincide with each other.
On the lower surface of the counter, a tool having a tool hook at the lower end and a screw cut at least on the lower end side is hung rotatably around its axis, and the second counter has a screw attached to the tool. A connector that is screwed together and restrains the lower surface of the second counter upward is connected, and a fixed seat is provided to protrude downward on the lower surface of the second counter, and the fixed seat and the second counter are One end of the connector is inserted into a gap between the two or a notch formed in the fixed seat itself, so that the second counter can be restrained in the vertical direction.

In such a configuration, the connecting member can be a bolt having a head formed at the upper end and a tool groove formed at the lower end.

[0013] A fixing seat is provided on the lower surface of the first counter on the side where the bolt is connected so as to protrude downward, and a substantially T-shaped groove in which a head of the bolt can be inserted from the side is directed downward. And the bolt head may be locked in the groove.

[0014]

[0015]

[0016]

In the connector screwed to the connecting device, the connecting device is rotatably connected to the first counter. By rotating the connecting device, the connector can be moved up and down. The height of the second counter restrained upward by this connector can be adjusted, and the level of the first counter can be adjusted.

When a bolt having a head and a tool groove is used as the connecting tool, a commercially available bolt obtained by cutting the tool groove can be used as it is.

In the case where the fixing member of the first counter is provided with a T-shaped groove, if this fixing seat is attached to the first counter in advance, the bolt can be easily inserted simply by inserting the bolt into the groove from the side. Can be hung below the first counter.

In the case where the connector is screwed to the fixed seat of the second counter, the binding force in the butting direction of the first and second counters can be obtained by the connector.

Further, in the case where one end of the connector is inserted between the fixed seat of the second counter and the counter or a notch provided in the fixed seat itself, the step of screwing is omitted.

In the height adjusting structure including the screws, the connector is screwed to the fixing seat of the second counter, and then the level of the second counter relative to the first counter is adjusted only by rotating the bolt. The height can be adjusted by a simple operation just by turning the bolt.

In the figure, two counters 1 and 2 fixed to the upper surface of the cabinet as an L-shaped planar layout by mutual arrangement have joining ends 1a and 2a which abut each other at an angle of 45 °. It is formed. A pair of fixed seats 3 and 4 using wood is provided in a portion along the joint ends 1a and 2a,
2 arranged in the depth direction. These fixed seats 3,
Numeral 4 is fixed to the lower surfaces of the counters 1 and 2 by an adhesive.

A connecting member 5 for connecting the counters 1 and 2 whose levels have been adjusted is incorporated between the pair of fixed seats 3 and 4. As the connecting tool 5, for example, a combination of a metal plate that cuts through the joining ends 1a and 2a of the counters 1 and 2 and a screw for fixing the plate to the counters 1 and 2 can be used.

The fixed seat 3 provided on the lower surface of the counter 1
The shape shown in FIG. 1 may be a cube or a rectangular parallelepiped, and any shape may be used as long as at least the lower surface and the upper surface have a parallel relationship. The fixed seat 4 provided on the other counter 2 is flatter than the fixed seat 3 on the counter 1 side, and is shown in FIG. 3 (viewed in the direction of the arrow AA in FIG. 1A). As shown in FIG. 5, a T-shaped groove 4a is formed from the surface facing the opposite side to the joint end 2a.

The head 6a of the bolt 6 can be inserted into the T-shaped groove 4a from the side of the fixed seat 4, and the bolt 6 is set in a state in which the head 6a rests on the engaging surface 4b of the groove 4a. It is hung on the fixed seat 4. The bolt 6 has a length whose lower end protrudes downward from the fixed seat 4, and has a tool hanging groove 6 b for hanging a screwdriver at the lower end.

A connector 7 connected to the fixed seat 3 is screwed to the bolt 6. The connector 7 uses a metal plate. The thickness of the connector 7 is such that the bolt 6 can be screwed into the connector 7, and is fixed to the lower surface of the fixed seat 3 by screws 8.

FIG. 4 shows the procedure for attaching the connector 7 to the fixed seats 3 and 4 in order.

The connector 7 is, as shown in FIG.
A female screw hole 7a into which the bolt 6 can be screwed is provided so as to be biased toward one end, and three through holes 7b through which screws 8 pass are provided at the other end. Then, as shown in the drawing, the bolt 6 is screwed into the female screw hole 7a so that the lower end thereof is slightly protruded, and the head 6a is inserted into the groove 4a of the fixed seat 4 with respect to the counters 1 and 2 arranged in abutting relation. . Thereby, the connector 7 is suspended from the fixed seat 4 via the bolt 6.

Next, as shown in FIG. 3C, the connector 7 at the level indicated by the broken line is raised until it hits the fixed seat 3. This operation can be performed by rotating the bolt 6 so that the connector 7 moves upward. The connector 7 is loosely abutted against the lower surface of the fixture 3 while maintaining the posture of the connector 7 in the posture shown in the figure. By screwing the screw 8 into the fixing seat 3 through the through hole 7b as shown in FIG. 2D, the connector 7 can be connected to the fixing seat 3 as shown in FIG.

Here, in FIG. 4, the levels of the counters 1 and 2 are drawn in the same state, but when they are assembled into an actual cabinet (not shown), the levels match as shown in FIG. Often not. For such a level mismatch, the following height adjustment is performed.

In FIG. 1, it is assumed that the level of the counter 1 arranged on the right side is appropriate. In FIG. 7A, the counter 2 is higher, so it is adjusted to lower it. This adjustment is performed by the tool groove 6b of the bolt 6.
, And the bolt 6 is rotated in a direction in which the bolt 6 penetrates the connector 7 downward. Thus, Counter 1
The counter 2 moves downward with respect to the connector 7 fixed to the side via the fixing seat 3 and located at an appropriate level, and is rotated by the driver D as shown in FIG. The height of the counters 1 and 2 can be matched.

In FIG. 1B, since the counter 2 is lower, the bolt 6 is rotated by the driver D in a direction opposite to the above example. As a result, the bolt 6 moves to the upper side of the connector 7, and the heights of the upper surfaces of the counters 1 and 2 in FIG. 4 can be matched as shown in FIG.

In such height adjustment between the counters 1 and 2, if the connector 7 on the counter 2 side is screwed to the fixed seat 3 on the counter 1 side with a screw 8, the subsequent height adjustment is performed by turning the bolt 6. It only needs to. And this connector 7
When the connector 7 is mounted on the fixing seat 3, the connector 7 itself is connected to the bolt 6 and one end thereof is restrained. Construction is easier than

In the height adjustment stage, the operation can be performed by simply turning the tool 6 by turning the driver D in the tool holding groove 6b of the bolt 6. For this reason, the worker who has sunk into the cabinet need only work with the driver D with one hand,
In addition, since one bolt 6 is rotated, the work time is reduced.

FIG. 5 is a schematic longitudinal sectional view of a main part showing another embodiment.

In this example, a T-shaped groove 3a is provided in the fixed seat 3 on the counter 1 side, and the bolt 6 is hung using the engaging surface 3b of the groove 3a. The groove 3a is formed penetrating in the depth direction of the counter 1 unlike the previous example,
The head 6a of the bolt 6 can freely move the groove 3a to a position orthogonal to the drawing. In this example, the connector 7 screwed and connected to the bolt 6 has a shape in which an intermediate portion is bent in a step-like manner. The connector 7 is connected to the fixed seat 4 on the counter 2 side by using a screw 8 in the same manner as in the previous example.

The height of the counters 1 and 2 can be adjusted by turning a tool on the tool groove 6b of the bolt 6 in the same manner as in the previous example, and adjusting the height of the counter 2 according to the direction of rotation. It can be adjusted to the counter 1 level of the opponent.

FIG. 6 shows a configuration in which the connection between the connector 7 and the fixed seat 4 in the example of FIG. 5 is restrained by being sandwiched between the fixed seat 4 and the lower surface of the counter 2 instead of a screw.

The upper end side of the fixed seat 4 and the counterpart fixed seat 3
A notch 4c is formed over the entire width on the side facing toward, and one end of the connector 7 is inserted into the notch 4c. Thereby, the connector 7 can be restrained in the vertical direction by the bottom surface of the notch 4 c on the lower surface of the counter 2.

FIG. 7 is a perspective view of the arrangement of the fixed seats 3 and 4 as viewed from the bottom side of the counters 1 and 2. In this example, the groove 3a of the fixed seat 3 is cut away from the near side of the counter 1 to the back side. Has a closed configuration. Therefore, connector 7
As shown in FIG. 6, when the bolts 7 are screwed in advance to be integrated into the fixing seats 3 and 4 and integrated in the direction shown in FIG. One end of the connector 7 and the one end of the connector 7 can be connected to the fixed seat 4 side, respectively.

Also in this example, the height of the counter 2 can be adjusted by positioning the bolt 6 and the connector 7 in the state of FIG. You can match the level between and.

FIG. 8 is a perspective view of another example of the fixed seats 3 and 4 as viewed from below the counters 1 and 2.

In the examples of FIGS. 2 and 7, a plurality of sets of the fixed seats 3 and 4 are arranged in the depth direction of the counters 1 and 2.
Instead of the arrangement of a plurality of sets, the fixing seats 3 and 4 are arranged one by one as long objects. A T-shaped groove 3c is formed in the fixed seat 3 in its entire length in the longitudinal direction, and a notch 4d is formed in the fixed seat 4 in its entire length.

By providing such grooves 3c and notches 4d, the positions of the bolt 6 and the connector 7 can be freely set in the depth direction of the counters 1 and 2.
Therefore, the degree of freedom of the mounting position of the bolt 6 and the connector 7 is improved, so that the work becomes easy, and the bonding area of the fixtures 3, 4 to the counters 1, 2 is increased, so that the mounting strength is also improved. .

FIG. 9 shows a modification in which a notch 4e is provided at an intermediate portion in the height direction of the fixed seat 4 in place of the example of FIG. 6, and the tip of the connector 7 is inserted into the notch 4e. Also in this example, the height of the counter 2 can be adjusted via the fixed seat 4 by rotating the bolt 6, and the level with the counter 1 can be adjusted.

FIG. 10 shows an example which can be used for connecting the counters 1 and 2 in addition to the height adjusting function.

This has a configuration in which a connecting bolt 9 is inserted into the fixed seat 4 having the configuration shown in FIG. 6 toward the counter 1 and the connecting bolt 9 is screwed to the connector 7. Since the connector 7 is connected to the counter 1 side by the bolt 6, the counters 1 and 2 can be connected by tightening the head 9 a of the connecting bolt 9 until it abuts against the end face of the fixture 4. By rotating the bolt 6 before this connection, the operation of adjusting the height of the counter 2 to match the level of the counter 1 can be performed in the same manner as in the previous example.
