Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple assembly type cabinet (knock down type cabinet) made of steel or the like.
[0002]
[Prior art]
The cabinet includes left and right side plates, a top plate, a side plate, and a back plate as essential elements, and shelves and doors are attached as necessary. The cabinets are roughly classified into those made of steel and wood, and those using both steel plates and wood boards.
[0003]
Since the cabinet has a large storage space due to its nature and is bulky, the cabinet is divided and packed and transported for each part, and is generally assembled at the installation site. Therefore, it is required to be able to be packed compactly and to be assembled as easily as possible. Moreover, it is necessary to provide the strength in the assembled state.
[0004]
JP-A-48-24869 discloses that in a wooden cabinet, a side plate, a top plate, and a bottom plate are connected to each other by a substantially L-shaped connecting member, and further, the side plate, the top plate, and the bottom plate are connected to each other. structure to fit the back plate in a groove formed in the rear inner surface is disclosed.
[0005]
When the side plate, the top plate, and the bottom plate are connected using the connecting member as in the above publication, the side plate, the top plate, and the bottom plate can have a simple structure, so that the packaging can be simplified and the assembly is facilitated. There are advantages.
[0006]
[Problems to be solved by the invention]
By the way, many cabinets have a frontage dimension larger than a depth dimension. In this case, the left-right width dimension of the back plate is larger than the front-rear width dimension of the side plate. For this reason, in the structure of the above publication, there is a problem that when packing in a state where each part is separated, there is at least the size of the area of the back plate, and thus there is a limit to downsizing.
[0007]
In addition, from the viewpoint of design etc., there is a demand to form the back of the cabinet flat, but in the structure in which the back plate is fitted in the groove formed in the side plate, the top plate and the bottom plate, the side plate and the top plate are necessarily Since the bottom plate protrudes behind the back plate, it is a problem that such a request cannot be met.
[0008]
An object of the present invention is to improve such a current situation.
[0009]
[Means for Solving the Problems]
Cabinet of the present invention is provided with a left and right side plates and the top plate and bottom plate and the back plate, between each other and the right and left side plates and the top plate is fitted to the hollow portion formed in the said side plate and the top plate It is connected through the connecting member which has an engaging part so that separation is impossible, and between the right-and-left side board and a bottom board has an engaging part which fits into the hollow part formed in the right-and-left side board and the bottom board. While being connected to each other through a connecting member, at least the back plate, the top plate, and the bottom plate are formed on the inner surface of the inner fitting portion projecting forward on the back plate and the rear inner surface of the top plate and the bottom plate. By fitting with the outer fitting portion, it is fitted so that it cannot be displaced forward and backward.
[0010]
In the first aspect of the present invention, the back plate is composed of a plurality of unit plates separated into the right and left, and the unit plates adjacent to the left and right are side edges of one unit plate and the side of the other unit plate . The fitting means formed at the end is held in the front, rear, left and right so as not to be separated, and the inner fitting portion of the lower side of each unit plate constituting the back plate and the outer fitting portion of the bottom plate are formed of the unit plate. The inner fitting portion is formed in a concave-convex shape so as to be fitted to the outer fitting portion of the bottom plate from above.
[0011]
According to a second aspect of the present invention, in the first aspect of the present invention, the inner fitting having the same cross-sectional shape as the inner fitting portion of the lower side is formed on the side and upper sides of the four rounds of each unit plate where the fitting means is not formed. On the other hand, the unit part is projected forward, while the rear inner surface of the top plate and the rear inner surface of the left and right side plates form an outer fitting part having the same cross-sectional shape as the outer fitting part of the bottom plate, as the outer fitting portion of the top plate to the inner fitting portion of the upper edge of the plate is fitted from above, the outer engaging portions of the side plates to the inner fitting portion of the sides of the unit plate is fitted from the left and right outer It has become.
[0012]
According to a third aspect of the present invention, in the second aspect, the left and right side plates, the top plate, and the bottom plate are formed such that the hollow portion and the outer fitting portion are formed by providing an inward projection made of a plate material inside the outer plate. In addition, a hollow portion is formed at the location of the outer fitting portion, while an engaging portion that fits into the hollow portion of the outer fitting portion is formed on the connecting member.
[0013]
[0014]
[Operation and effect of the invention]
According to the present invention , in the simple assembly type cabinet using the connecting member, the back plate is divided into a plurality of right and left parts, so that even a cabinet whose frontage dimension is larger than the depth dimension can be packed compactly. For this reason, it is convenient to carry.
[0015]
In addition, since the inner fitting part provided on the back plate projects forward, it is possible to align the rear surface of the back plate with the rear end surfaces of the side plate, top plate, and bottom plate. Nevertheless, it is possible to design the back with a refreshing design. Further, since the outer fitting portion and the inner fitting portion are uneven, it is possible to make a sturdy structure while being an assembly-type cabinet.
[0016]
According to the second aspect of the present invention, when the inner fitting portion provided on the back plate and the outer fitting portion provided on the outer peripheral plate such as the side plate are fitted, the integrity of the back plate and the outer peripheral plate is remarkably increased. Therefore, although it is a simple assembly type cabinet, it can have a sturdy structure.
[0017]
If the flat cross-sectional shape of the left and right side plates and the side cross-sectional shape of the top plate and the bottom plate are formed in the same shape as in the embodiment, the manufacturing process of the side plate, the top plate, and the bottom plate can be shared, so the cost is reduced. There is an advantage that can be suppressed. Moreover, since one type of connecting member can connect between the side plate and the top plate and between the side plate and the bottom plate, this aspect can also contribute to cost reduction.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0019]
(1). Outline FIG. 1 is a schematic perspective view of a cabinet in an assembled state, and FIG. 2 is a front view in a state in which members are separated. As shown in these drawings, the cabinet includes left and right side plates 1. , and one of the top plate 2, and one of the bottom plate 3, the body is constituted by the back plate 4 of the 2 division made from a single position plate 5 two.
[0020]
The shelf board 6 can be mounted in multiple stages inside the main body. Further, the main body may remain open, or a rotary door 7 may be attached as shown in FIG. 1, or a sliding door door may be attached. It is also possible to attach a drawer to the inner surface of the side plate 1 by attaching a rail.
[0021]
The side plate 1 and the top plate 2 and the side plate 1 and the bottom plate 3 are connected by a connecting member 8. The flat cross-sectional shape of the side plate 1 and the side cross-sectional shapes of the top plate 2 and the bottom plate 3 are the same, and therefore, the four connecting members 8 are common.
[0022]
In the case of this embodiment, the frontage dimension of the cabinet is approximately twice the depth dimension. Also, the height dimension is set to about twice or about three times the frontage dimension (it should be twice or more). Legs 9 are attached to the four corners of the bottom plate 3.
[0023]
Note that the cabinet has various specifications, and the frontage dimensions and depth dimensions are the same or about 1.5 times, or the height dimensions are about the same as the frontage dimensions or about 1.5 times. The ratio of each dimension of frontage, depth and height varies.
[0024]
Next, details of each part will be described with reference to FIG. 3 is a separated perspective view of the upper end portion of the side plate 1 and the connecting member 8, FIG. 4 is a separated perspective view of the side plate, the connecting member 8, and the top plate 2, and FIG. 5 is a separated perspective view of the back plate 4 and the bottom plate 3. FIG. 6 is a plan sectional view of the rear part of the cabinet, and FIG. 7 is a vertical side view of the rear part of the cabinet.
[0025]
(2). Side plate, top plate, bottom plate The side plate 1 is provided with a flat outer plate 10, arranged on the inner surface of the outer plate 10 on the first protrusion 11 extending along the longitudinal center line and on both the front and rear sides thereof. Two second protrusions 12 and a third protrusion 13 connected to the front and rear end surfaces of the outer plate 10 are formed. Since each of the protrusions 11, 12, and 13 is made of a plate material, first to third hollow portions 14, 15, and 16 are formed at locations surrounded by the protrusions 11, 12, and 13 and the outer plate 10. Has been.
[0026]
The third protrusion 13 is a stepped portion 13a whose outer side is low. Moreover, although the 1st protrusion 11 and the 2nd protrusion 12 are the same protrusion dimensions, as the 3rd protrusion 13 can understand from FIG. 6, for example, the protrusion dimension of the high part of the 3rd protrusion 13 is the 1st protrusion 11 and the 2nd protrusion. The dimension is lower than 12 by at least the same dimension as the plate thickness.
[0027]
A cutout 17 is formed on the upper and lower ends of the side plate 1 so as to cover the entire first protrusion 11 and a part of the second protrusion 12. Further, a number of slit-like engagement holes 18 are formed in the second protrusion 12 of the side plate 1 at appropriate vertical intervals. The shelf board 6 can be mounted by a bracket (not shown) locked in the engagement hole 18.
[0028]
For example, as can be easily estimated from FIG. 4, the top plate 2 and the bottom plate 3 have the same structure as the side plate 1, and the first to third protrusions 11 to 13 and the hollow portions 14 to 16 and the notches 17 are formed. ing. In addition, when attaching the rotational door 7, it is sufficient to attach a hinge to the first projection 11 on the front side of the side plate 1. When attaching a sliding type sliding door, the front side between the top plate 2 and the bottom plate 3 is attached. A rail may be attached to the first protrusion 11.
[0029]
(3) Connecting member The connecting member 8 is L-shaped and symmetric in the front-rear direction when viewed from the front. And one 1st engaging part 20 inserted in the 1st hollow part 14 of each board 1, 2, 3 which comprises the outer periphery of a cabinet, and the 2nd 2nd engaging part 21 inserted in the 2nd hollow part 15 And a third engaging portion 23 that fits into the third hollow portion 16, and the connecting member 8 is fitted into each of the plates 1, 2, 3 with little or no backlash.
[0030]
The front ends of the engaging portions 20 to 22 are formed in a tapered shape so that the fitting into the hollow portions 14 to 16 is facilitated.
[0031]
Since the notch 17 in each plate 1, 2 and 3 are formed, and the base side portion and the first engagement portion 20 and the second engaging portion 21 is integrally connected to the plate portion 23, this end The strength of the connecting member 8 is remarkably high, and as a result, a strong structure can be obtained while being a simple assembly type cabinet.
[0032]
The first engaging portion 20 and the second engaging portion 21 have the same protruding dimension, but the third engaging portion 22 has a smaller protruding dimension than the first engaging portion 20 and the second engaging portion 21. It has become. This is because the projecting dimensions of the first engaging portion 20 and the second engaging portion 21 are increased due to the notches provided in the respective plates 1, 2, 3. Of course, you may align the protrusion dimension of each engaging part 20-22 equally.
[0033]
The plates 1, 2, 3 and the connecting member 8 are fixed by screws 24 that penetrate the second protrusion 12. Since the screws 24 are screwed into the connecting member 8 from the inside of the cabinet in this way, the aesthetics are not impaired.
[0034]
As shown in FIGS. 3 and 4, in addition to the screw holes 29 into which the screws 24 for fixing the connecting member 8 to the outer peripheral plates 1, 2, 3 are fitted, the nut is non-rotatably fitted into the connecting member 8. A possible auxiliary hole 30 penetrates.
[0035]
The auxiliary holes 30 are used for connecting adjacent cabinets with screws and nuts when the cabinets are arranged side by side in the horizontal direction or vertically. For this reason, the auxiliary hole 30 is stepped so that the nut can be fitted and the head of the screw is hidden (that is, a counterbore hole). The nut may be embedded by an insert molding method.
[0036]
(4). As shown in the back plate Figure 5 and Figure 6, the squareness of the forward projection 25 as part of the fitting means on the side edge of one of the single-position plate 5 constituting the back plate 5 is bent formed, other the side edge of the single-position plate 5 of, as a part of the fitting means and holding portion 26 of the square which embrace the forward projection 25 is bent formed, thereby, two single-position plate 5 back and forth It is held on the left and right inseparable. In addition, the protrusion 25 and the holding part 26 may have other shapes.
[0037]
The third protrusion 13 of each of the plates 1, 2, 3 is an inward fitting portion described in the claims, and on the other hand, a protrusion 25 and a holding portion 26 are formed in the unit plate 5 constituting the back plate 4. On the three sides that are not formed, concave and convex inner fitting portions 27 that fit into the third projections 13 of the side plate 1, the top plate 2, and the bottom plate 3 are provided to project forward. The upper and lower inner fitting portions 27 are fixed to the bottom plate 3 and the top plate 2 with screws 28.
[0038]
As shown in FIG. 7, the dimension L <b> 1 between the upper and lower outward fitting portions 27 in the unit plate 5 constituting the back plate 4 is set to be the same or smaller than the height dimension H of the side plate 1. Therefore, in a separated state of each part can be fitted into the side plate 1 to the single-position plate 5. Further, the protrusion dimension L2 of the inner fitting portion 27 in the unit plate 5 is set to about twice the maximum thickness T of the plates 1, 2, and 3.
[0039]
Therefore, as shown roughly in FIG. 8, a single-position plate 5 two arranged so that the inner fitting portion 27 is opposed to the inside of the two single-position plate 5, two side plates 1, the top plate 2 and the bottom plate 3 can be fitted together. A space is vacant on the side of the top plate 2 and the side plate 1, but the connecting member 8 and screws 24 and 28 may be accommodated in this space.
[0040]
In this way, by devising each dimension, the cabinet can be packed in a compact manner even though it is a cabinet in which the inner fitting portion 27 is provided on the back plate 4 (unit plate 5) .
[0041]
The ratio of the frontage, depth, and height of the cabinet varies, but if the back plate 4 is divided into two unit plates 5 , the side plate 1, the top plate 2, and the bottom plate 3 are in any case. In a state where the outer peripheral plate is sandwiched between the back plates 5, it is preferable to set the inner fitting portion 27 so as not to protrude outside the group of outer peripheral plates.
[0042]
The assembly procedure of the cabinet is shown in FIG. That is, the top plate 2 and the bottom plate 3 with previously mounting the connecting member 8 above, can you configure the Setai 4 joined together two single-position plate 5, then the side plates 1 and the back The plate 4 and the bottom plate 3 may be connected, and finally the top plate 2 may be connected to the side plate 1 and the back plate 4.
[0043]
And in the assembled state, the inner fitting portion 27 provided around the back plate 4 is fitted to the third protrusions (outer fitting portions) of the side plate 1, the top plate 2 and the bottom plate 3, The entire cabinet has a very sturdy structure. Further, since the two unit back plates 5 are fitted in such a manner that they cannot be displaced back and forth, the back plate 4 can be made to have a sturdy structure, although it is a split type back plate 4.
[0044]
Although not shown in the drawing, an engagement hole 18 similar to that of the side plate 1 is formed in the holding portion 26 (and the protrusion 25) of the back plate 4, and a rear end portion of the shelf plate 6 is attached by a bracket attached thereto. It is also possible to support. In this way, the support strength of the shelf board 6 can be improved.
[0045]
(5). Others The present invention can be embodied in various ways other than the above embodiment. For example, when a protrusion or a fitting portion is formed on a side plate, a top plate, or a bottom plate, it may be formed by bending a single steel plate into an uneven shape. Further, the fitting portion does not necessarily have to be formed in an uneven shape.
[0046]
The form of a connection member and the connection aspect of the plates by this connection member can also be embodied variously. The connecting member is not limited to a mode in which the engaging portion is inserted into the hollow portion of the plate, but may be formed in a simple L shape and fastened to the plate with screws. Further, the back plate may be divided into three or more.
