Description

The present invention relates to an adjuster device capable of appropriately supporting a base of a furniture main body such as a storage and a cabinet with a simple structure and laying work, a base and furniture to which the adjuster device is applied, and an adjuster suitable for them. .

As this type of adjuster device, for example, those shown in Patent Documents 1 and 2 are known. These units have an adjuster arranged on a base that supports the furniture body, and the shaft portion of the adjuster prevents the adjuster's ground plate from rotating in an unfavorable direction when the adjuster's shaft portion is rotated. A channel portion provided at a position that supports the rail is fitted into an upward channel-shaped rail member installed on the floor, and the rotation of the adjuster is prevented by the face plate portion rising from the horizontal portion of the rail. And the said earthquake resistance of a base is improved by fixing the said channel part to a floor.

However, with such a structure, a separate rail member must be adopted, and the structure for preventing the adjuster from rotating and the structure for fixing the floor depend on the structure and positional relationship of the rail and base. Therefore, there is a problem that the structure is complicated and the construction procedure increases.
The present invention has been made paying attention to such problems, and can reduce the number of parts and appropriately prevent the adjuster from rotating without being influenced by the structure of the base with a simple configuration. An object of the present invention is to provide a new and useful adjuster device that can easily give a certain level of vibration resistance.

  In order to achieve this object, the present invention takes the following measures.

  That is, the adjuster device of the present invention is applied to a base that supports a furniture body, and a substantially vertical screw hole is provided in the base, and a rotatable shaft portion of the adjuster is screwed into the screw hole. In this case, the adjuster is configured to interfere with the portion displaced from the shaft portion of the adjacent adjuster so that the portion displaced from the shaft portion interferes with each other to restrict rotation.

With this configuration, the shaft portion can be rotated while the adjuster rotation is restricted, so the base level adjustment is performed by screw-feeding the screw hole of the base while maintaining the adjuster orientation properly. be able to. In addition, since the rotation of the adjuster is controlled by a structure that causes the adjusters to interfere with each other, there is no need to use separate members or the surrounding structure such as the base, and it can be easily applied to various bases and assembled. Can also be done simply.

In order to obtain the adjuster's interference state stably and reliably with a simple structure, the adjuster shall have a shaft part rotatably attached to a part of the ground plate, and the ground plates may interfere with each other directly or indirectly. It is preferable to restrict the rotation.

In order for the structure for interference to succeed in stabilizing the grounding state at the same time, it is desirable to restrict the rotation by bringing the ends of the grounding plates into contact with each other.

In particular, in order to realize a flat rotation regulation structure, it is desirable to regulate rotation by bringing the vertical surfaces of the ground plates into contact with each other.

On the other hand, when it is desired to secure a sufficient interference area, it is also effective to provide a rising portion on a part of the ground plate and restrict the rotation using this rising portion.

In order to improve the stability more effectively without introducing a separate leg, the center of the grounding plate is farther from the center of the base when the grounding plate is rotated out of interference. It is preferable to be able to be grounded in such a state.

For the same purpose, it is also effective to allow the grounding plate to be grounded in a state where the center portion of the grounding plate is outside the shaft portion when the grounding plate is rotated after releasing the interference state.

As a particularly effective mode, there is a configuration in which at least a part of the ground plate can be grounded in a state of protruding from the base extension by releasing the interference state and rotating the ground plate.

If the adjusters according to the above adjuster devices are arranged at the four corners of the base so that the adjusters paired in the short side direction interfere with each other, the distance from the shaft portion to the interference position can be shortened. From the viewpoint of restricting rotation, it is possible to avoid an unnecessarily large ground plate.

In addition, the furniture body is placed on the base and the furniture is configured. The center of the ground is moved outside the adjuster shaft by rotating the adjuster by releasing the interference between the adjusters paired in the short side direction. If it can be positioned, the ground contact width in the short side direction that easily tilts among the furniture will be expanded, so that the earthquake resistance can be effectively improved, thereby effectively reducing the need for floor fixing, etc. It becomes possible to do.

  Since the present invention has the configuration described above, it is possible to easily and appropriately prevent the ground plate or the like from rotating in an unfavorable direction during adjustment of the adjuster without using a separate member or depending on the base structure or the like. Accordingly, it is possible to provide an excellent adjuster device which can be easily applied to various bases and can effectively improve workability and earthquake resistance.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows furniture in which a furniture body 2 such as a storage is placed on a base 1.

As shown in FIGS. 2 and 3, the base 1 has a front frame 11, a rear frame 12, and left and right side frames 13 having a U-shaped cross section assembled into a rectangular frame corresponding to the shape of the furniture body 2. Thus, an upwardly concave concave-shaped member 14 extending in the front-rear direction is bridged between the front frame 11 and the rear frame 12 just inside the left and right side frames 13 of the frame. Then, in the vicinity of the four corners of the base 1, an adjuster device A is constructed using the above-mentioned base material 14, and through the adjuster device A, through the adjuster adjustment before or after the furniture body 2 is placed on the base 1. An appropriate support state can be provided.

Specifically, as shown in FIG. 4 and FIG. 5, the adjuster device A includes a nut member 3 provided on the base member 14 and having a substantially vertical screw hole 3 a in the installed state, and the nut member 3. The adjuster 4 is attached by screwing the shaft portion 41 into the screw hole 3a.

The base member 14 has a cross-section inverted hat shape with a side plate 14b standing on both sides of the bottom plate 14a and having a flange on the upper end side thereof. The screw passage hole 14c is provided in the screw passage hole 14c. The nut member 3 is firmly attached under the bottom plate 14a so that the above-described screw holes 3a are matched. Of course, the nut member 3 may be fixed on the bottom plate 14a, or a screw hole may be provided in the bottom plate 14a itself instead of the nut member 3.

On the other hand, the adjuster 4 is provided with an inverted dish-shaped bulging portion 42 for attaching the shaft portion 41 at a position displaced toward the one end portion 40a side of the ground plate 40 using a rigid plate material such as an iron plate as the ground plate 40. Therefore, by arranging one end 41 a of the shaft portion 41 in the cavity of the bulging portion 42 and caulking the vicinity of the one end 41 a of the shaft portion 41, the shaft portion 41 is made the top wall of the bulging portion 42. The part is supported so as to be rotatable and hardly displaceable in the axial direction. As shown in FIG. 3, on the other end portion 41b side of the shaft portion 41, there is an engaging portion 41c such as a square hole or a groove that can rotate the shaft portion 41 using a tool such as a wrench or a screwdriver. It is provided. In this embodiment, the distance d2 from the shaft 41 to the other end 40b of the ground plate 40 is longer than the distance d1 from the shaft 41 to the one end 40a of the ground plate 40. The other end portion 40b is extended, and the ground plate 40 has a substantially rectangular shape as a whole, and the other end portion 40b is orthogonal to the extending direction in plan view as shown in FIGS. It has a direction end face 40b1. The end face 40b1 forms a vertical surface that stands up almost vertically as shown in FIG.

As shown in FIGS. 3 and 5, the other end portions 40b1 of the ground plates 40 of the pair of adjusters 4 and 4 positioned in the short side direction (depth direction) along the side frame 13 of the base 1 are mutually connected. A screw which is a screwed end of both adjusters 4 and 4 so that the end faces 40b1 of the other end portion 40b1 of the ground plate 40 are in contact with or in close proximity to each other. The distance d2 from the center of the shaft portion 41 of the adjuster 4 to the end face 40b1 of the other end portion 40b is set to have a value of about 1/2 with respect to the center distance L between the holes 3a and 3a.

For this reason, if the adjuster 4 tries to rotate even a little, the end faces 40b of the other end portion 40b of the ground plate 40 interfere with each other, and the rotation of the adjuster 4 is mutually regulated.

In addition, the ground plate 40 interferes with rotation when the other end portions 40b and 40b collide with each other in a state where the base 1 is placed on the floor F via the adjuster 4. If the other end portions 40 b do not collide with each other in a state where they are not grounded to F, each ground plate 40 is rotatable around the axis of the shaft portion 41. For this reason, before or after laying the base 1, the ground plate 40 can be rotated by temporarily lifting a part of the base 1, and if necessary, the adjuster adjustment position is slightly shifted to adjust the other end 40 b. If they are displaced in the thickness direction, the interference state can be canceled. Then, if each adjuster 4 is rotated about the axis of the shaft portion 41, the other end portion 40b can be extended in the back direction and grounded as shown in FIGS. . In this embodiment, a part of the ground plate 40 on the other end portion 40b side is extended outwardly of the base 1 through a gap between the lower surface of the front frame 11 and the rear frame 12 and the floor F in a state where the base plate 40 is rotated 180 °. The front frame 11 and the rear frame 12 can be grounded while protruding outward from the outer surface.

As described above, the adjuster device A of the present embodiment is applied to the base 1 that supports the furniture body 2, and the base 1 is provided with the screw hole 3 a in the substantially vertical direction, and the adjuster 4 is rotated in the screw hole 3 a. The free shaft portion 41 is screwed together. And the adjuster 4 is comprised so that the site | part displaced from the axial part 41 may interfere with the site | part displaced from the axial part 41 of the adjacent adjuster 4, and may mutually regulate a rotation.

With such a configuration, the shaft portion 41 can be rotated while the rotation of the adjuster 4 is restricted. Therefore, the screw hole 3a of the base 1 is screwed to the adjuster 4 while keeping the orientation of the adjuster 4 appropriately. Can be adjusted. In addition, since the rotation restriction of the adjuster 4 is realized by a structure that causes the adjusters 4 and 4 to interfere with each other, there is no need to employ a separate member or to be influenced or influenced by the peripheral structure including the base 1. It can be easily applied to the base of the machine and can be easily assembled.

Specifically, the adjuster 4 is a part in which the shaft portion 41 is rotatably attached to a part of the ground plate 40, and the ground plate 40, 40 is directly interfered with each other so as to regulate the rotation. Since the ground plate 40 is laid on the floor F so that the heights thereof are aligned, a stable interference state between the ground plates 40 and 40 can be easily created. In addition, since the grounding plate 40 itself, which is the subject of the original rotation restriction, is provided with a rotation restriction function, the desired effect can be reliably achieved.

More specifically, the other end portions 40b of the ground plate 40 are brought into contact with each other to restrict the rotation, and if the ground plate 40 is extended to a position where the other end portions 40b can interfere with each other, the contact is naturally made. Since a sufficient ground contact area is ensured for the ground plane 40, the stability of the base 1 is effectively enhanced thereby.

The ground plate 40 regulates the rotation by bringing the vertical surfaces 40b1 which are the end surfaces of the other end portion 40b into contact with each other, and can regulate the rotation within the thickness of the ground plate 40, so that a flat rotation regulating structure is easy. It becomes feasible.

Further, in the adjuster device A of this embodiment, the center portion of the ground plate 40 is moved from the state of FIGS. 3 and 5 as shown in FIGS. 6 and 7 by rotating the ground plate 40 after releasing the interference state. Since it can be grounded in a state of being farther from the center of the base 1, the grounding width between the adjusters 4 and 4 is expanded by the rotation of the grounding plate 40, and the same effect is obtained as when the stable legs are replaced. In particular, when priority is given to stable grounding, it is possible to respond effectively by only rotating the grounding plate 40.

Specifically, the rotation of the ground plate 40 causes the center portion to be inward of the shaft portion 41 as shown in FIGS. 6 and 7 from the state where the center portion is inside the shaft portion 41 as shown in FIGS. Since the grounding is newly performed in a state of being on the outer side with respect to the portion 41, the deterring force effectively acts on the behavior in which the base 1 tends to tilt to the outside of the shaft portion 41.

In particular, since the ground plate 40 can be grounded in a state where at least a part thereof protrudes from the outer extension of the base 1 by rotation, the effect as a stable leg can be effectively exhibited.

In the base 1 of this embodiment, the adjusters 4 according to the above adjuster device A are arranged at the four corners so that the adjusters 4 and 4 that make a pair in the short side direction of the base 1 interfere with each other. The distance from the shaft portion 41 to the interference position can be short, and at least from the viewpoint of restricting rotation, it is possible to effectively avoid the ground plate 40 from becoming larger than necessary.

And the furniture of this embodiment is configured by placing the furniture body 2 on the base 1, and by rotating the adjuster 4 by releasing the interference between the adjusters 4 and 4 which make a pair in the short side direction, Since the grounding center can be positioned outside the shaft 41 of the adjuster 4, the grounding width in the short-side direction, which is easy to tilt, can be extended without using a stabilizing leg or the like. And can be extremely effective when there is a situation where it is not desired to provide a hole for fixing furniture on the floor or wall.

As mentioned above, although one Embodiment of this invention was described, the specific structure of each part is not limited only to embodiment mentioned above.

For example, as shown in FIG. 8, if a rising portion 40x is provided in a part of the ground plate 40 and rotation is restricted by using this rising portion 40x, the thickness of the ground plate 40 is sufficiently exceeded. It is effective in pursuing a more reliable rotation restricting effect because it is possible to secure a reliable interference region. Further, when the adjuster 4 is attached to the base 1 and handled integrally, if a resin cap or the like is fitted to the rising portion 40x of the pair of adjusters 4, the interference state is maintained even during distribution or construction. Therefore, the convenience of handling can be improved effectively.

When the grounding plate 40 is rotated as shown in FIGS. 6 and 7 and used as a stable leg, the rising portion 40x is located at a portion protruding from the base 4, but it is necessary. Accordingly, by providing a cover or the like that encloses the rising portion 40x and flattening the protruding portion, it is possible to obtain a form that does not hinder the use.

  Further, in the above embodiment, the ground plates are directly interfered with each other. However, an aspect in which another member is attached to the ground plate and the ground plates are indirectly interfered with each other is also possible, and other configurations also have the gist of the present invention. Various modifications are possible without departing from the scope.
