Description

  The present invention relates to furniture and a rail unit therefor that can effectively be retrofitted with a shutter using a side frame of the furniture body.

  With recent demands for improving security, conventional furniture has been subjected to various security measures.

  For example, in doors and sliding door furniture that do not include a locking mechanism, there are many examples in which security measures are taken by newly incorporating a locking mechanism.

However, for items that do not have an opening / closing member such as open storage furniture, it is better to use the shutter to open and close the entire storage space rather than to introduce doors and sliding doors. It is thought that it is effective also in doing.

At that time, it is convenient if a shutter can be attached to the existing furniture as a retrofit, but there is no conventional furniture that enables such a correspondence.

Although it is not furniture, what was shown to patent documents 1, 2 is known as what attached the shutter along a window frame. These have a three-sided frame using a vertical frame, base material, attachment material, etc., with the outer wall surface of the window frame as a foothold, a rail part is provided on the attachment material, etc., and a shutter is provided on the rail part. The guide is provided, and has an advantage that a shutter can be retrofitted when necessary, and such a mounting structure can be incorporated into furniture.
Utility Model Registration No. 2534719 Reality 6-23679

However, in furniture, there is no wall surface that serves as a foothold for the shutter frame outside the side frame, so we have devised how to secure the foothold and bring the rail part forward, as well as special features in furniture. It is necessary to consider the circumstances.

That is, in FIG. 1 and the like of the above-mentioned Patent Document 1 that discloses a retrofit shutter, a vertical frame is attached to a wall surface, an attachment material is attached to the vertical frame, and an attachment piece projecting from the attachment material is connected to an outer surface of the vertical frame. After positioning, the rail portion is formed at the front end of the attachment material. The attachment material has a vertical frame in a portion protruding further outward than the above-mentioned attachment piece. A joint part is also provided. However, in the case of furniture, if such an attachment piece or engagement piece exists on the outer surface of the side frame, the appearance is greatly impaired. In addition, in the case of furniture, a plurality of side frames are abutted to each other in the width direction, or a plurality of side frames are abutted against a wall. Even if it is going to employ | adopt, it is difficult to employ | adopt said attachment structure substantially, since an attachment piece or an engaging part interferes with the furniture main body and wall which adjoin.

On the other hand, in FIG. 1 etc. of Patent Document 2, the base material and the attachment material are attached to the wall surface so as to be added forward while forming the fastening mechanism inside, and the rail portion is formed at the front end thereof. The engagement between the members can be performed within the width dimension of the base material or attachment material, but the situation is different from the vertical frame provided near the window frame, and the width dimension of the side frame is limited in furniture. Therefore, such a fastening mechanism is difficult to adopt.

In view of such a problem, the present invention can appropriately attach the shutter frame in consideration of the structure peculiar to the furniture body, and the mounting structure is not affected by the arrangement state of the furniture. It is an object of the present invention to provide a furniture having a new and useful shutter mounting structure and a rail unit therefor.

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

That is, the furniture of the present invention is attached to the base member on the front surface of the side frame of the furniture body, and the attachment piece provided on the base member is attached to the inner surface of the side frame of the furniture body. by attaching a, constitutes the shutter frame by these base members and the attachment member, substantially in correspondence with the thickness of the side frame of the furniture body the width of the shutter frame, the shutter frame through the spliced piece furniture A rail portion having a rail groove having a depth dimension substantially corresponding to the thickness dimension of the side frame of the furniture body is formed on the front end side of the shutter frame while being positioned in the width direction with respect to the side frame of the main body. outer surface and set by opening the and inwardly so as to be substantially flush outer surface of the shutter frame consisting of outer surface against the outer surface of the side frame of the furniture body of the base member parts The side edges each corresponding shutter the rail portion is engaged with the thickness direction, characterized by being adapted to guide the shutter along the rail portion.

With this configuration, if the base member is attached first, and then the attachment material is attached, the shutter frame is combined to form a strong shutter frame. Therefore, the shutter frame is effectively arranged on the side frame of the furniture body. can do. In addition, the base member is provided with an attachment piece that comes into contact with the inner surface of the side frame of the furniture body, and this attachment piece is used to position the shutter frame in the width direction with respect to the side frame of the furniture body. Thus, the shutter frame can be accurately attached to the side frame, and a smooth opening / closing operation of the shutter can be ensured. In particular, considering that the side frame of the furniture body is generally narrow, it is difficult to firmly fix the shutter frame only on the front side of the side frame, and the assistance by the contact piece is extremely effective in suppressing the wobbling of the shutter frame. To be. In addition, since the accessory piece is positioned on the inner surface of the side frame, it is not difficult to attach the shutter frame due to the accessory piece even when furniture or walls are closely adjacent to each other. Even when used in a case, it is possible to effectively avoid a situation in which the appearance of the furniture is damaged.

In this case, in order to achieve the above effect, it is desirable that the outer surface of the shutter frame is positioned substantially flush with the outer surface of the side frame of the furniture body or on the inner side.

In order to effectively secure the mounting strength near the base end of the shutter frame, the inner wall is taken out from the side wall of the base member, while the inner wall and the rear wall of the base member attached to the front surface of the side frame of the furniture body It is desirable that a gap is formed between the two and the rear wall of the attachment material is closely inserted into the gap in the front-rear direction.

In order to properly prevent the left and right shutter frames from wobbling without impairing workability, at least the width direction is closely related between the baseboard arranged in front of the bottom plate of the furniture body and the left and right shutter frames. It is effective to provide a mating engaging portion and regulate the change in the separation distance between the shutter frames by this engaging portion.

As a preferred embodiment in this case, the engaging portion includes a slit provided in the shutter frame, and a plate-like engaging claw that protrudes from the baseboard and engages the slit at least in a direction perpendicular to the thickness direction. In which the engaging portion is concealed behind the upright portion of the skirting board.

In order to configure the furniture as described above by retrofitting, a base member that is attached to the front surface of the side frame of the furniture main body and has an attachment piece that contacts the inner surface of the side frame of the furniture main body at the position, An attachment material to be attached, and a shutter frame is constituted by the base member and the attachment material, a rail portion is provided on the front end side of the shutter frame, and an outer surface of the rail portion is substantially surface with respect to an outer surface of the shutter frame. It is preferable to use a rail unit in which a rail groove is provided in an inward opening at a single position .

It is preferable that the rail unit further includes a skirting board that tightly engages with the left and right shutter frames via the engaging portion at least in the width direction and regulates a change in the separation distance between the shutter frames in this state.

  Since the present invention has the above-described configuration, it can be easily adopted, and can be attached with a shutter regardless of the arrangement of the furniture body, and even for a relatively narrow side frame of the furniture body. It is possible to provide new and useful furniture in which a shutter can be attached with sufficient strength.

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

  The furniture of this embodiment shown in FIG. 1 is storage furniture in which a shutter 2x is attached to the existing furniture main body 1 as a retrofit.

  As shown in FIG. 2, the furniture main body 1 connects the upper and lower end portions of the left and right side frames 11 so as to form a front-view frame body with a top plate 12 and a bottom plate 13, and a back plate 14 on the back surface. A storage space S in which a shelf board or the like can be placed is formed.

  And the base member 31 and the attachment material 32 are attached to the finding surface 11a which is the front surface of the side frame 11 to constitute the shutter frame 3 shown in FIGS. 1 and 2, and the lower plate member 41 is interposed on the front surface of the bottom plate 13. The baseboard 42 is attached across the lower end portions of the left and right shutter frames 3.

  More specifically, the base member 31 has a substantially U-shaped cross section as shown in FIGS. 3 to 6, and the rear wall 31 a is brought into contact with the finding surface 11 a of the side frame 11, so that the rear wall A side wall 31b orthogonal to 31a extends forward, and a front wall 31c is bent inward at the front end of the side wall 31b. The furniture main body 1 is located at a position continuous with the rear wall 31a of the base member 31. A contact piece 31d that contacts the inner surface 11b of the side frame 11 and positions in the width direction is provided so as to protrude rearward. Further, a U-shaped attachment piece 33 that also serves as a reinforcement is firmly attached to the inner surface of the side wall 31 a of the base member 31, and between the inner wall 33 a of the attachment piece 33 and the rear wall 31 a of the attachment member 31. In addition, a gap δ opened to the storage space S side is formed. And the screw v1 which is a fixing tool is inserted in the insertion holes h11 and h12 (see FIG. 4) provided in the rear wall 33a of the mounting piece 33 and the rear wall 31a of the base member 31, and this is inserted into the side frame 11 of the furniture body 1. The base member 31 is attached to the side frame 11 by being fastened to the finding surface 11a.

  The attachment member 32 is a U-shaped member that is disposed so as to abut against the base member 31 from the inside. The rear wall 32a is inserted into the gap δ, and the side wall 32b is attached to the attachment wall 33b of the attachment piece 33. The front wall 32c is bent outward at the front end of the side wall 32b, and the front wall 32c is abutted substantially flush with the front wall 31c of the base member 31. Then, a screw v2 as a fastening tool is inserted from the inside into the insertion hole h21 provided in the side wall 32b of the attachment member 32, and the screw v2 is fastened to the screw hole h22 provided in the corresponding portion of the mounting wall 33b. The attachment member 32 is attached to the base member 31 so as to constitute the shutter frame 3 having a hollow body as a whole. At the front end of the attachment member 32, a rail part 34 having an inward U-shaped cross section composed of a rear piece 34a, a side piece 34b, and a front piece 34c in contact with the side wall 32b and the front wall 32c is bonded and The attachment member 32 is integrally provided by an appropriate method such as screwing, integral molding, or plastic deformation, and the inner side thereof forms a rail groove 34x that can be engaged with the side edge 2xa of the shutter 2x. The rail portion 34 conceals the joint x (see FIG. 6) between the front wall 31 c of the base member 31 and the front wall 32 c of the attachment member 32 behind the rail portion 34.

As shown in FIG. 7, the rail portion 34 has an end portion slightly above the lower end of the hollow portion of the shutter frame 3 formed by abutting the base member 31 and the attachment material 32, and the lower portion serves as a baseboard attachment region 3 a. Opened, the front wall 31c of the base member 31 and the front wall 32c of the attachment member 32 are provided with rectangular slits 3x facing the baseboard attachment region 3a at the joint x portion at two locations, upper and lower. The rail portion 34 does not necessarily have to be provided integrally with the hollow portion of the attachment material 32 from the beginning, and the hollow portion of the attachment material 32 is first attached to the base member 31 and then the attachment material 32 is hollow. You may make it attach the rail part 34 with respect to a part.

The outer surface of the shutter frame 3 in FIG. 6 configured as described above (that is, the outer surface of the side wall 31b of the base member 31 and the outer surface of the side piece 34b of the rail portion 34) is substantially the same as the outer surface of the side frame 11 of the furniture body 1. The width of the furniture body 1 is set so as to be flush with the point where the contact piece 31d contacts the inner surface 11b of the side frame 11 and the screws v1 and b2 are fastened from the front and the inner side. Within the dimension d (see FIG. 2), the attachment of the base member 31 → the attachment material 32 can be performed from the front side.
Further, the width dimension of the shutter frame 3 substantially corresponds to the thickness dimension of the side frame 11 of the furniture body 1, and the rail groove 34 x of the rail portion 34 has a depth dimension substantially corresponding to the thickness dimension of the side frame 11 of the furniture body 1. Have .

  On the other hand, as shown in FIGS. 7 to 10, the lower collar member 41 has a substantially inverted L-shaped cross section, and the vertical surface portion 41 a is brought into contact with the front surface of the bottom plate 13 of the furniture body 1 to stand upright. By inserting a screw v3 as a fastening tool through an insertion hole h31 provided in the surface portion 41a and fastening it to the front surface of the bottom plate 31, the lower collar member 41 is attached to the bottom plate 13, and in this state the flat portion 41b is moved forward. It is extended.

On the other hand, the skirting board 42 has an inverted L shape whose cross section faces the lower collar member 41, and as shown in FIGS. 7 and 8, both end portions 42a are positioned in the skirting board attachment region 3a. In addition, a part 42b1 other than the end of the flat surface part 42b is mounted so as to sink under the flat surface part 41b of the lower collar member 41 between the inner sides of the left and right shutter frames 3, and the rear elevation surface part 42c is lowered. It is made to contact | abut to the elevation part 41a of the collar member 41. FIG. Then, the screw v4, which is a fastening tool, is inserted from above into the insertion hole h41 provided in the flat portion 41b of the lower collar member 41, and is fastened to the screw hole h42 provided in the corresponding portion of the flat portion 42b of the base plate 42. Thus, the baseboard 42 is attached to the lower collar member 41. Further, as shown in FIGS. 7 and 10, a pair of upper and lower engaging claws 42x that are bent from the inner surface portion 42d and project rearward are formed at both ends of the baseboard 42. When both end portions 42a of the tree 42 are attached to the baseboard mounting region 3a, these engaging claws 42x are inserted tightly in the thickness direction and width direction into the slit 3x of the shutter frame 3, and these engagements The engaging portion Y of the present invention is formed by the claw 42x and the slit 3x. In this state, the front piece 34c of the rail portion 34 and the front vertical surface portion 42e of the base plate 42 are substantially flush with each other, and the lower end of the rail groove 34x formed between the front piece 34c and the rear piece 34a of the rail portion 34 is It becomes a closed state.

  1 and 2, the shutter unit 2 is disposed on the top plate 12 of the furniture body 1, and the left and right edges of the shutter 2x of the shutter unit 2 correspond to the rail grooves of the left and right rail portions 34, respectively. 34x is engaged in the thickness direction. The shutter unit 2 incorporates the shutter 2x so as to be able to extend / rewind. The shutter unit 2 is fixed to the top plate 12 of the furniture body 1 with screws, and the side frame front end 21 is connected to the front end of the furniture body 1, that is, the finding surface 11a of the side frame 11. It is arranged at a position that protrudes further forward, that is, a position that substantially corresponds to the amount of the shutter frame 3 taken out. As a result, when the shutter 2x is put in and out through the operation portion 22 provided at the lower end thereof as shown by an arrow in FIG. 1, the side edges 2xa of the shutter frame 3 corresponding to the side edges 2xa respectively correspond to the imaginary lines in FIG. The shutter 2x can be guided along the shutter frame 3 by engaging with the groove 34x in the thickness direction. The reason why the shutter frame 3 is taken out in this way is that, in the present embodiment, it is assumed that an article having a relatively deep depth such as a medical record is stored. However, it goes without saying that such a purpose of use is merely an example.

  In addition, a positioning member (not shown) having protrusions inserted into the respective hollow portions is interposed between the hollow portion of the shutter frame 3 and the side frame front end 21 of the shutter unit 2. In addition, in FIG. 4, notches that allow clearance to interfere with the screws v <b> 1 and v <b> 2 are provided as necessary at the front end of the front wall 31 c of the base member 31 and the front end of the rear wall 32 a of the attachment member 32. Further, as shown in FIG. 2, a cap c of the same color system is attached to the insertion hole h42 of the lower collar member 41.

As described above, the furniture according to the present embodiment is configured such that the base member 31 is provided on the finding surface 11 a of the side frame 11 of the furniture body 1, and the attachment piece 31 d provided on the base member 31 is provided on the side frame 11 of the furniture body 1. mounting in a state of being spliced to the inner surface 11b, by attaching the attachment member 32 to the base member 31, these base members 31 and the attachment member 32 constitute a shutter frame 3, furniture body the width of the shutter frame 3 The shutter frame 3 is positioned in the width direction with respect to the side frame 11 of the furniture body 1 through the attachment piece 31d. And the rail part 34 which has the rail groove 34x of the depth dimension corresponding to the thickness dimension of the side frame 11 of the furniture main body 1 in the front-end side of this shutter frame 3 is used for the outer surface of the said rail part 34, and the said base member 31. The outer surface of the shutter frame 3 composed of the outer surface is provided so that the outer surface of the shutter body 3 is substantially flush with the outer surface of the side frame 11 of the furniture body 1 and is opened inward. 2xa is engaged in the thickness direction so that the shutter 2x can be guided along the rail portion 34.

If comprised in this way, if the base member 31 is attached first and attachment member 32 is attached after that, these will combine and the shutter frame 3 with intensity | strength will be comprised, Therefore The said frame is attached to the side frame 11 of the furniture main body 1. The frame 3 can be effectively arranged. In addition, the base member 31 is provided with a contact piece 31d that comes into contact with the inner surface 11b of the side frame 11 of the furniture body 1, and the contact piece 31d positions the shutter frame 3 in the width direction with respect to the side frame 11 of the furniture body 1. As a result, the shutter frame 3 can be accurately attached to the side frame 11 of the furniture body 1 and a smooth opening / closing operation of the shutter 2x can be ensured. In particular, considering that the side frame 11 of the furniture body 1 is generally narrow, it is difficult to firmly fix the shutter frame 3 only by the finding surface 11a, but the shutter frame 3 is wobbled with the assistance of the attachment piece 31d. It can be effectively prevented. Further, since the attachment piece 31d is positioned on the inner surface 11b of the side frame 11, it is difficult to attach the shutter frame 3 due to the attachment piece 31d even when furniture and walls are closely adjacent to each other. In other words, it is possible to effectively avoid a situation in which the appearance of the furniture is damaged even when used alone.

In this case, since the outer surface of the shutter frame 3 is positioned at a position that is substantially flush with the outer surface of the side frame 11 of the furniture body 1, a plurality of furniture bodies 1 are closely arranged adjacent to each other in combination with the above configuration. In this case, or even when the outer surface of the side frame 11 of the furniture body 1 is in contact with the wall, the shutter 2x can be retrofitted without moving the furniture body 1, and the outer surfaces are aligned. It becomes possible to maintain the appearance in a good state.

Further, the inner wall 33a is taken out from the side wall 31b of the base member 31 through the attachment piece 33, and the rear wall 31a of the base member 31 and the inner wall 33a that are attached to the finding surface 11a of the side frame 11 of the furniture body 1 are connected. Since the gap δ is formed between them and the rear wall 32a of the attachment member 32 is closely inserted in the gap δ in the front-rear direction, the base member 31 includes not only the rear wall 31a but also the side wall 31b with the inner wall 33a. And the rear wall 32a of the attachment member 32 is also closely inserted between the inner wall 33a and the rear wall 31a of the base member 31. Since it is in a state of being indirectly attached and supported by the finding surface 11 a of the side frame 11, the finding surface near the base end of the shutter frame 3 as a whole even when the finding surface 11 a is relatively narrow. It is possible to sufficiently secure the mounting strength with respect to 11a.

In particular, the base member 31 is attached to the finding surface 11a from the front by using the screw v1, and the attachment member 32 is abutted and attached from the inner side so as to hide the screw v1, and at least the screw v1 is attached in the attached state. Since it is located in the shutter frame 3 and is not visible from the front, even if the screw v1 is heavily used and the shutter frame 3 is attached by retrofitting, it is possible to effectively prevent the appearance of the furniture from being damaged. it can. Furthermore, since the attachment member 32 is abutted against the base member 31 from the inner side, the rail is brought out at the tip as compared with the case where the attachment member 32 is abutted to the front of the base member 31. The stability of the portion 34 can be further increased.

  At this time, even if the screw v1 is concealed, if the joint x between the base member 31 and the attachment member 32 located on the front surface of the shutter frame 3 is exposed, securing the appearance is overlooked. Since x is concealed behind the rail part 34 located in front of the shutter frame 3, the effect of concealing the screw v1 can be ensured.

In the above, if a three-way frame including the left and right shutter frames 3 and 3 is assembled from the beginning, the strength between the shutter frames 3 and 3 can be secured from the beginning, but the three-way frame is attached to the existing furniture body 1. Is a serious problem. On the other hand, in the present embodiment, an engagement portion Y that is tightly engaged at least in the width direction is provided between the skirting board 42 disposed in front of the bottom plate 13 of the furniture body 1 and the left and right shutter frames 3. Since the engagement portion Y regulates the change in the separation distance between the shutter frames 3 and 3, even if the shutter frame 3 and the baseboard 42 are assembled separately, the rail portion 3 can be opened by the baseboard 42. It is possible to regulate, and it is possible to ensure substantially the same strength as when a three-way frame is used. In addition, it is possible to effectively save the labor of connecting the attachment member 32 and the skirting board 41 with a screw or the like.

The engaging portion Y also includes a slit 3x provided in the shutter frame 3 and a plate-like engaging claw 42x that protrudes from the baseboard 42 and engages the slit 3x at least in a direction perpendicular to the thickness direction. Since the engaging portion Y is concealed behind the upright portion of the base plate 42, the engaging portion Y can be configured with a simple structure, and the engaging claw 42x is provided with the shutter frames 3 and 3. Since the force in the opening direction is received in the direction orthogonal to the thickness direction, it is possible to sufficiently ensure the strength.

Furthermore, as described above, the base member 31 is attached to the finding surface 11a of the side frame 11 of the furniture body 1 from the front by using the screw v1, and the base member 31 is butted from the inner side so as to hide the screw v1. The base frame 31 and the attachment material 32 constitute the shutter frame 3, the rail portion 34 is provided on the front end side of the shutter frame 3, and the outer surface of the rail portion 34 is provided on the shutter frame 3. If the rail unit in which the rail groove 34x is opened inward is provided at a position that is substantially flush with the outer surface of the door, the present invention can be easily applied to the existing furniture even after retrofitting. It becomes possible.

In this rail unit, a skirting board 42 which is engaged with the left and right shutter frames 3 tightly in the width direction at least via the engaging portion Y and regulates the change in the separation distance between the shutter frames 3 and 3 in this state. In addition, the mounting strength can be increased more effectively.

The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, even when the outer surface of the shutter frame is positioned on the inner side of the outer surface of the side frame of the furniture body, the same effect as in the above embodiment can be obtained. Further, in the above embodiment, the position of the shutter 2x is taken forward to store articles having a relatively deep depth such as a medical record in the storage space S. However, when the depth is not particularly problematic, the shutter frame 3 Of course, it is also possible to suppress the amount of protrusion. Furthermore, when it is not retrofitted, it is also possible to use a shutter unit that is not retractable so as to be retracted to the back plate side of the furniture body. Furthermore, the present invention is not necessarily limited to the mode in which the shutter unit is arranged on the top plate of the furniture body. For example, in the case where a digging space is formed in a part of the wall and the furniture body is accommodated in the space. If the wall surface exists in front of the space and the shutter unit can be fixed to the wall surface, the present invention can be effectively applied in the same manner as described above.
