Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a new bookshelf, and particularly to an improvement of the shelf boards of a wooden bookcase.

Background technology and its problems When it comes to wooden bookshelves, the shelf boards used for them are generally also made of wood.
In addition, plywood is used for bookshelves including shelf boards in order to reduce their weight and to eliminate misalignment.

By the way, shelf boards are normally held horizontally in order to place items such as book cases, but such horizontal shelves do not hold relatively heavy items such as book cases. It is desirable that the material has high flexural rigidity so that it does not bend even under the load of 1000 yen, and the wood grain pattern is also an important element in improving the design effect of bookshelves and the like.

However, wooden shelves have lower bending rigidity than metal shelves, so if a large number of heavy items such as bookcases are placed on them for a long time, they will permanently bend, making the items unstable. In addition, it becomes extremely unsightly.

Therefore, conventionally, for this type of wooden bookshelf,
The length of the shelf board in the across direction is set to be as short as 1/2 or less of the left-right width of the bookshelf, or if the shelf board is long, the middle part is supported by a support member.

However, in the former case, the interior of the bookshelf is unnecessarily partitioned, making it difficult to use, and in the latter case, the support members become an obstacle to putting in and taking out bookcases, etc., which has disadvantages.

Purpose of the invention Therefore, the present invention increases the bending rigidity over the entire length of the shelf board of a wooden bookshelf to make it easier to lengthen the shelf board, and also strengthens the support parts for the frame support at both ends of the shelf board.
A further object of the present invention is to provide a bookshelf that can hold hanging bookends on the lower surface of the shelf.

Summary of the invention In order to achieve the above object, the present invention provides a wooden shelf having multiple shelves, each shelf having at least one embedded metal reinforcement over the entire length between the support ends on the back side. The metal reinforcing material has a bent cross-sectional shape to increase the bending rigidity of the shelf board and make it easier to lengthen the shelf. By forming an engaging part that is removably supported by the support column, the supporting parts at both ends of the shelf board are strengthened, and it also serves as a holder for the hanging book end of the shelf board one step below. .

Embodiments of the invention Hereinafter, specific embodiments of the invention will be described with reference to the drawings.

FIGS. 1 to 7 show an embodiment of the bookshelf according to the present invention. Reference numeral 1 is a wooden shelf board made of plywood or a single board. A substantially U-shaped groove 2 is formed along the entire length thereof, and a metal reinforcing material 3 for improving the bending rigidity of the shelf board 1 is embedded integrally within this groove 2.

As shown in FIGS. 2 and 3, the metal reinforcing material 3 has a channel portion 3a having a width smaller than the width of the groove 2 and the same length as the shelf board 1, and a channel portion 3a on both ends of the channel portion 3a. Edge pieces 3b, 3c are connected by being bent horizontally in the direction, embedded pieces 3d, 3e are formed by bending the edge of each edge piece 3b, 3c upward, and are formed at both ends of the channel part 3a in the longitudinal direction. The metal reinforcing member 3 is composed of supporting pieces 3f and 3g, and the channel portion 3a thereof is inserted into the groove 2, and the embedded pieces 3d and 3e are inserted into the slit groove formed on the lower surface of the shelf board 1. 4 and 5, and is integrally fixed to the shelf board 1 by inserting a wood screw 7 into a hole 6 made in the top piece of the channel part 3a and screwing it into the shelf board 1. . Further, in the other side of the channel portion 3a, a large number of holes 9 for attaching book ends 8 are bored at regular intervals.

Reference numeral 10 denotes a wooden end member attached at right angles to the rear end surface of the shelf board 1, and is used to position the insertion end of a bookcase or the like.
Pins 11 for holding the shelf board 1 to a bookshelf frame, etc. are protruded from both ends of the back side of the bookshelf board 1, and book end mounting grooves 12 are provided on the front surface of the part of the shelf board 1 that protrudes from the bottom side. is formed.

When assembling the shelf board configured as described above to a bookshelf, as shown in FIGS. 4 to 6, the pins 11 of the end member 10 are inserted into the holes drilled in the rear supports 14 constituting the bookshelf frame 13. 15, the support pieces 3f and 3g provided at both ends of the channel portion 3a are attached to the support pin 16 screwed into the front strut 17 in advance.
Engage the letter-shaped notches 3fa and 3ga. In this way, the shelf board is attached to the bookshelf frame 13.

Further, as shown in FIG. 7, the book end 8 includes a U-shaped engaging portion 8a and a rod-shaped engaging portion 8b at both ends, and the two tips of the U-shaped engaging portion 8a are connected to metal reinforcing members 8a. The bookend 8 is attached to the back surface of the shelf board 1 by engaging the attachment hole 9 of the bookend 8 and engaging the rod-shaped engagement portion 8b with the attachment groove 12 of the end member 10.

In the bookshelf configured as described above, since the metal reinforcing material 3 is embedded in the shelf board 1, the bending rigidity of the shelf board 1 is significantly improved compared to one made only of wood. As a result, the shelf board can be made longer, and the intermediate support material used in the past can be made unnecessary, and the supporting parts with the bookshelf pillars at both the left and right ends of the shelf board can be eliminated without damaging them. . Furthermore, since the metal reinforcing material 3 is embedded in the lower surface of the shelf board 1, the metal reinforcing material 3
This does not impair the design effect of the shelf board or even the bookshelf, and the book end 8 can also be easily attached.

In addition, in the above embodiment, the case where one metal reinforcing material 3 is embedded in the shelf board 1 has been explained, but the structure is not limited to this, and two or more metal reinforcing materials 3 may be provided. Of course, the shape is not limited to that of the embodiment.

Effects of the invention As mentioned above, the bookshelf of the present invention is a wooden bookshelf having multiple shelves, each shelf having at least one metal reinforcement embedded in the entire length between the support ends on the back side. The metal reinforcing material has a bent cross-sectional shape, and an end member that is perpendicular to the shelf and projects vertically is provided on the rear end surface of the shelf over its entire length. The metal reinforcing material of the shelf board has engaging parts formed at both left and right ends thereof to be removably supported by the pillars of the frame of the bookshelf. A large number of locking holes are formed at regular intervals in the longitudinal direction, and a locking groove extending in the longitudinal direction is formed on the front surface of the downwardly protruding portion of the end member, and the locking groove and the metal A locking hole formed in the reinforcing material is characterized in that the hanging book end of the shelf board one step below is held. Therefore, according to the bookshelf of the present invention, the bending rigidity of the shelf board itself can be improved, and as a result, a long shelf board that does not permanently bend can be easily realized.
The design effect of being made of wood is not impaired, and the hanging book end can be easily held.
