Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shelf holding structure suitably used for wooden shelves such as bookshelves.

[Prior Art] The shelf holding structure used for wooden shelves such as bookshelves has so-called dowels protruding horizontally from predetermined locations on the inward facing side of the side panels, and recesses extending from the end surface to the bottom surface of the shelf. It is known that the shelf board is removably installed between the side plates by providing a recessed part and engaging the dowel with the recessed part.

[Problems to be Solved by the Invention] However, in this type of wooden shelf, the lower half of each dowel generally protrudes below the lower surface of each corresponding shelf board. Therefore, in addition to being unsightly, the protruding portion tends to get in the way of putting in and taking out books and the like. Such a problem can be solved by deepening the recess provided in the shelf, but even if this is done, the recess remains open on the lower surface of the shelf, which is undesirable in terms of appearance.

Furthermore, since such dowels are small and have a rollable shape, they are easily lost, and if they are lost, there is a problem in that it becomes impossible to properly hold the shelf board.

In addition, as another shelf board holding structure that can prevent the loss of small parts, for example,
There is also one shown in Publication No. 11068. That is, this thing has a plurality of sets of circular engagement holes formed in front and rear pairs on the inner surface of the side plate, and dowel-shaped protruding legs that form front and rear pairs on one side of a synthetic resin rail member that extends front and rear. The rail member is attached to the inner surface of the side plate by integrally projecting the rail member and fitting the projecting legs into specific engagement holes. A horizontal groove is provided on the side surface of the shelf board, and by engaging the horizontal groove with the rail member, the shelf board is installed between the side boards.

However, with such a configuration, the vertical thickness of the rail member cannot be made smaller than the diameter of the dowel-shaped protruding leg. In particular, what is described in this publication is the rail member,
Since it supports not only the shelves but also the drawers, the thickness of this rail member must be large in terms of strength. Therefore, a shelf board that needs to have a horizontal groove on its side surface capable of accommodating such a rail member becomes even thicker. This causes a problem in that the storage space formed between the shelf boards is unduly narrowed.

Furthermore, if the circular engagement hole and the dowel-shaped protruding leg are engaged with each other with some slack, the frictional holding force between them will be lost, and the rail member will easily fall when the shelf board is installed or removed. Therefore, in such a structure, a slightly hard fitting dimension is usually selected, and the protruding leg is fitted into the engagement hole using a rubber hammer or the like. However, when the front and rear pair of protruding legs are respectively fitted into the front and rear pair of engagement holes,
Due to the relative error between the pitch between the protruding legs and the pitch between the engagement holes, large variations occur in the force for mounting and dismounting the rail member, which may make it difficult to remove the rail member from the side plate.

Furthermore, in such a device, if the upper and lower pitches of the plurality of pairs of engagement holes are made too short, the strength of the side plate may be significantly reduced. Therefore, there is also the problem that it is difficult to increase the degree of freedom in adjusting the shelf board.

The present invention solves the above-mentioned problems, allows the shelf board to be installed easily and reliably, and also prevents the shelf board from being dragged when pulling out books, etc. It is an object of the present invention to provide a shelf board holding structure that can effectively prevent such problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the following configuration.

That is, the shelf holding structure for a wooden shelf according to the present invention includes shelf posts made of sheet metal that are provided on the side panels of the wooden shelf and form a space inside, and transparent holes that are bored in the shelf posts that open the space to the outside. A shelf holding structure comprising a hole and a connecting member attached to the through-hole portion to support the shelf toward the shelf pillar, the connecting member having a base end close to or near the shelf. A horizontal plate disposed horizontally in contact with each other, a horizontal protrusion extending horizontally into the through hole from the base end of the horizontal plate, and a horizontal protrusion protruding upward from the insertion end of the horizontal protrusion. and an engaging piece that engages with the inner surface of the shelf pillar are integrally molded from a sheet metal material, and the shelf board has an opening on the end face and back surface thereof, and the front end side corresponds to the thickness dimension of the horizontal board. A horizontal groove having a width dimension and a step with a drop on the ceiling surface near the back is provided, and the horizontal plate of the connecting member is placed in this horizontal groove, and the front end of the horizontal plate is at the front end of the horizontal groove. It is characterized in that the horizontal plate is engaged to a position where the rear end of the horizontal plate falls into the stepped portion.

[Function] With such a configuration, the horizontal plate of the connecting member is placed in an inclined position such that the tip thereof is higher than the base end, and the horizontal protruding piece and the engaging piece provided at the base end are connected to the shelf pillar. into the space through the through hole, and then
When the horizontal plate is tilted to a horizontal position, the horizontal projecting piece comes into contact with the lower opening edge of the through hole, and the engaging piece comes into contact with the inner surface of the shelf pillar, so that the horizontal plate becomes horizontal. held in position. In this state, the shelf board is horizontally moved rearward from the front side of the wooden shelf, and the horizontal board is fitted into the horizontal groove of the shelf board, thereby completing the erection of the shelf board.

With the shelves installed in this way, all the connecting members are hidden by the shelves and are not exposed to the outside, and there are no protrusions or recesses on the top or bottom surfaces of the shelves. It turns out.

In addition, since the connecting member is made of sheet metal and can be hung on the shelf pillar with the above-mentioned configuration, the horizontal plate is much thinner than the above-mentioned rail member. However, no problems occur. Therefore, the horizontal groove of the shelf board can also be made much smaller in vertical dimension than the conventional horizontal groove described above.
Therefore, the side plate can be made thinner and the storage space can be effectively expanded.

Moreover, if the horizontal projecting piece and the engaging piece are made to engage with the through hole provided in the sheet metal shelf pillar in the state described above, the engaging part can have some dimensional space. However, problems such as the connection member falling easily do not occur. That is, according to the procedure described above, the connecting member can be easily attached to and removed from the side plate, but since the connecting member is not held by friction, there is no possibility that the connecting member may fall accidentally. That will no longer be the case.

In addition, if a through hole is provided in the sheet metal shelf column and the sheet metal horizontal projecting piece and the engaging piece are engaged with this through hole, the vertical pitch of this through hole can be adjusted as necessary. It is also possible to make it very short.
That is, in the present invention, since the through holes are not directly provided in the side plate, even if a large number of such through holes are provided at short pitches, problems such as a sudden decrease in the strength of the side plate will not occur. Moreover, the through hole is
Since it can be formed all at once on a sheet metal shelf column by pressing or the like, there is no increase in the number of man-hours during production. Therefore, the degree of freedom in adjusting the height of the shelf board can be improved without causing a decrease in strength or an increase in cost.

Furthermore, in this invention, instead of simply attaching a plate-shaped metal plate to the side plate, column-shaped sheet metal shelf posts are provided on the side plate, so that the side plate is particularly effectively reinforced by the shelf posts. This makes it possible to effectively suppress warping of the side panels.

Furthermore, in the present invention, the horizontal plate of the connecting member is engaged with the horizontal groove until the front end of the horizontal plate reaches the front end of the horizontal groove and the rear end of the horizontal plate falls into the stepped portion. There is. Therefore, accurate positioning can be achieved simply by pushing the shelf board into the final position, and the work can be reliably completed when it is confirmed that the back side of the shelf board sinks. However, in this state, the shelf is accommodated between the front end of the horizontal groove and the step and cannot be moved forward or backward, so the back side of the shelf is intentionally raised higher than the front side. Unless the horizontal plate is removed from the horizontal groove, the shelf board will not be pulled out forward. Furthermore, it is highly unlikely that such a movement would occur accidentally on a shelf in use with an overload applied. Therefore, this product can exhibit an effective pull-out prevention effect. Furthermore, since the width of the opening at the front end of the horizontal groove corresponds to the thickness of the horizontal plate, in the above-mentioned engagement position, the horizontal groove tightly clamps both the upper and lower surfaces of the horizontal plate, and Acts as a reinforcing material to increase rigidity. Therefore, even if the horizontal plate is made thin, it is possible to effectively prevent the distal end side of the horizontal plate from elastically deforming downward and becoming incompletely engaged with the horizontal groove.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

The wooden shelf shown in Fig. 1 consists of fixed shelf boards 2, 3 and a movable shelf board 4 installed between the left and right side boards 1. The shelf board holding structure according to the invention is applied.

As shown in FIGS. 2 and 3, in this shelf holding structure, two shelf posts 5 are buried in parallel on the inner surface 11 side of each side plate 1, and the movable shelf 4 is connected to a connecting member 6. It is constructed and supported between the shelf pillars 5 via the shelf pillars 5.

The movable shelf board 4 is made of wood, and grooves 41 having small vertical dimensions are provided substantially horizontally at both ends thereof. As shown in FIGS. 2 and 6, these horizontal grooves 41 are open only to the end surface 42 and back surface 43 of the movable shelf board 4, and are open only to the front surface 43 of the movable shelf board 4.
The fourth side is closed, and the opening width dimension corresponds to the thickness dimension of a horizontal plate 61 of the connecting member 6, which will be described later, and a stepped part 41a with a drop is formed on the ceiling surface 41c near the back surface. .

As shown in FIG. 2, the shelf pillar 5 is made of sheet metal and has a U-shaped cross section.
1 is fitted into a groove 12 provided in the side plate 1 so as to be flush with the inward surface 11 of the side plate 1, and a space 52 is formed inside thereof. A through hole 53 opening the space 52 to the outside is formed in the shelf post 5. The through hole 53 is
It has a rectangular shape as shown in FIG. 1, and a plurality of holes are formed at predetermined intervals in the vertical direction.

The connecting member 6, as shown in FIGS. 2 to 4,
A horizontal plate 61 disposed horizontally with its base end 61a close to or in contact with the side plate 1; and a horizontal protrusion 62 extending horizontally into the through hole 53 from the base end 61a of the horizontal plate 61. , the insertion end 6 of this horizontal projecting piece 62
The inner surface 54 of the shelf pillar 5 projects upward from the shelf pillar 2a.
It is made of sheet metal and includes an engaging piece 63 that engages with. Specifically, the horizontal plate 61 has a long rectangular shape with a length corresponding to the distance between the shelf columns 5. The horizontal projecting piece 62 is attached to the horizontal plate 61 so that it can extend horizontally into the through hole 53.
are formed to protrude from the base end 61a of the base end 61a corresponding to each shelf post 5, respectively. Engagement piece 63
is a tongue-like piece that integrally projects upward from the insertion end 62a of the horizontal protruding piece 62, and is arranged at a position where it engages with the inner surface 54 of the shelf post 5 when the connecting member 6 is attached. It is something that will be done.

Next, a procedure for installing the movable shelf board 4 between the side boards 1 will be explained. First, as shown in FIG.
Horizontal projecting piece 62 and engaging piece 63 provided on 1a
is inserted into the space 52 through the through hole 53 of the shelf post 5. Thereafter, the horizontal plate 61 is tilted to a horizontal position using the base end 61a as a fulcrum. As a result, the horizontal projecting piece 62 comes into contact with the opening edge 53a of the through hole 53, and the engaging piece 63 engages with the inner surface 54 of the shelf post 5, so that the horizontal plate 61
is held in a horizontal position. In this state, as shown in FIG. 6, the movable shelf board 4 is moved horizontally backward from the front side of the wooden shelf, and the horizontal board 61 is placed in the horizontal groove 41 so that the front end 61c of the horizontal board 61 is horizontal. It reaches the front end 41b of the groove 41 and the rear end 6 of the horizontal plate 61.
The installation of the movable shelf board 4 can be completed by engaging the movable shelf board 4 to the position where the movable shelf board 1d falls into the step part 41a.

With such a configuration, the movable shelf board 4 can be connected to the horizontal projecting piece 62 and the engaging piece 6 of the connecting member 6.
It can be securely held on the side plate 1 in three parts. In this state, all the connecting members 6 are hidden by the movable shelf board 4 and are not exposed to the outside.
This means that there are no protrusions or recesses at all. Therefore, there is no problem such as protrusions protruding from the lower surface 46 of the movable shelf board 4 and getting in the way of taking in and taking out books and other items, and the movable shelf board 4 also has an excellent appearance. Furthermore, the connecting member 6 has a horizontal plate 61
Since the shelf board 4 is mainly composed of non-rollable shapes, it is difficult to cause inconveniences such as losing parts and making it impossible to properly hold the shelf board 4.

Further, since the connecting member 6 is made of sheet metal and can be hung on the shelf pillar 5, there is no problem even if the horizontal plate 61 is made much thinner than the rail member. No problems occur. Therefore, the horizontal groove 41 of the shelf board 4 can also be made much smaller in vertical dimension than the conventional horizontal groove. Therefore, the shelf board 4 can be made thinner and the storage space can be effectively expanded.

Moreover, if the horizontal projecting piece 62 and the engaging piece 63 are made to engage with the through hole 53 provided in the sheet metal shelf column 5, even if the engaging part is given dimensional space, There is no problem in which the connecting member 6 tends to fall. That is, according to the procedure described above, the connecting member 6 can be easily attached to and removed from the side plate 1, but since the connecting member 6 is not held by friction, the connecting member 6 may be accidentally removed. There will be no more falling.

Furthermore, if a through hole 53 is provided in the shelf column 5 made of sheet metal, and the horizontal projecting piece 62 made of sheet metal and the engaging piece 63 are engaged with this through hole 53, the vertical pitch of this through hole 53 can be adjusted. can be made very short if necessary. That is, in this embodiment, since the through holes are not directly provided in the side plate, even if a large number of such through holes 53 are provided at short pitches, problems such as a sudden decrease in the strength of the side plate 1 will not occur. Moreover, since the through hole 53 can be formed in the sheet metal shelf column 5 all at once by pressing or the like, the number of man-hours during manufacturing does not increase. Therefore, the degree of freedom in adjusting the height of the shelf board 4 can be improved without causing a decrease in strength or an increase in cost.

Furthermore, in this embodiment, instead of simply attaching a plate-shaped metal plate to the side plate 1, column-shaped shelf posts 5 made of sheet metal are provided on the side plate 1. 1 can be particularly effectively reinforced, and warping of the side plate 1 can be effectively suppressed.

Furthermore, in this embodiment, the horizontal plate 61 of the connecting member 6 is placed in the horizontal groove 41, and the front end 61 of the horizontal plate 61 is
1c reaches the front end 41b of the horizontal groove 41 and the rear end 61d of the horizontal plate 61 is engaged until it falls into the step portion 41a. Therefore, accurate positioning can be performed simply by pushing in the shelf board 4, and the work can be reliably completed when it is confirmed that the back surface 43 side of the shelf board 4 sinks. In this state, the shelf board 4 is accommodated between the front end 41b and the step part 41a of the horizontal groove 41, and cannot be moved forward or backward. Unless the horizontal plate 61 is pulled out from the horizontal groove 41 by lifting it higher than the side, the shelf board 4 will not be pulled out forward. Furthermore, it is highly unlikely that such an operation would occur accidentally on the shelf board 4 in a used state with an upper load applied thereto. Therefore, this product can exhibit an effective pull-out prevention effect. Moreover, since the width of the opening on the front end 41b side of the horizontal groove 41 corresponds to the thickness of the horizontal plate 61, the horizontal groove 41 tightly clamps both the upper and lower surfaces of the horizontal plate 61 in the above-mentioned engagement position. , acts as a reinforcing material that increases rigidity in the plane direction. Therefore, even if the horizontal plate 61 is made thin, the tip 61b side of the horizontal plate 61 elastically deforms downward,
It is possible to effectively prevent the shelf board 4 from being tilted due to incomplete engagement with the horizontal groove 41.

Note that the number of shelf boards, the number of shelf posts, etc. are not limited to those of the illustrated embodiment, and can be modified in various ways without departing from the spirit of the present invention.

[Effects of the invention] Since the present invention has the above-described configuration, it is possible to accurately hold the shelf board using simple parts, and it also prevents problems such as loss of parts when installing and removing the shelf board. A shelf board holding structure for a wooden shelf that can be easily and reliably carried out without causing damage, and that can effectively eliminate the inconvenience of obstructive parts protruding from the bottom surface of the shelf or exposing recessed parts. It is possible to provide

Moreover, the present invention can provide the following special effects compared to the conventional example in which the shelf boards are held using rail members.

That is, according to the present invention, the shelf board can be held by a horizontal plate that is much thinner than the rail member, so that the shelf board can be made thinner without difficulty. Therefore, the storage space formed between the shelf boards can be effectively expanded.

Moreover, since the connecting member is integrally molded from sheet metal as described above, the connecting member can be easily attached to and removed from the side plate, but the connecting member will not fall accidentally. Therefore, the height position of the shelf board can be easily changed, and the shelf board can be held reliably.

In addition, a through hole is provided in the shelf post provided on the side plate, and the horizontal protruding piece and the engaging piece are engaged with this through hole, so the height of the shelf plate can be adjusted without reducing strength or increasing costs. The degree of freedom regarding adjustment can be improved.

Furthermore, in this invention, instead of simply attaching a plate-shaped metal plate to the side plate, column-shaped sheet metal shelf posts are provided on the side plate, so that the side plate is particularly effectively reinforced by the shelf posts. This makes it possible to effectively suppress warping of the side panels.

Furthermore, in the present invention, the horizontal plate is dropped between the front end of the horizontal groove and the step, so that the work of positioning and engaging the shelf board in a predetermined position can be performed as smoothly as possible. In addition, it is also possible to effectively prevent the shelf board from being dragged when pulling out books, etc. On top of that,
At the engagement position, the horizontal grooves of the shelf board sandwich the horizontal plate of the connecting member to improve the strength in the plane direction, so even if a thin horizontal plate is used as described above, the horizontal plate will not be deformed. It is possible to effectively prevent a situation in which the state of engagement with the shelf board becomes incomplete.
