However, since the shelf dowel receiver of the shelf board mounting device has a complicated internal structure such as a lock lever of another member being slidably fitted inside, the outer shape becomes large and the bottom of the shelf board is bottomed. Since the shape (depth and inner diameter) of the recesses provided at the four locations is large, the manufacturing cost is high, and it is difficult to apply to a relatively thin and small shelf board.

Further, the shelf board mounting device is mounted by drilling insertion holes for dowels at four locations on both side walls of the storage portion, and inserting the shelf dowels into these insertion holes. These shelf dowels are formed in a simple pin shape as in the conventional one, and the pin-shaped shelf dowels are inserted and attached to the insertion holes for the shelf dowels drilled in the side wall.

Therefore, for example, when the above-mentioned shelf board mounting device is used for a shelf support such as a bookshelf, a heavy object such as a book is repeatedly placed on the shelf board, and an excessive load is repeatedly applied in the bending direction of the shelf dowel. Within a short period of time, there was a problem that the mounting state of the shelf dowel became loose, the shelf receiving state became unstable, or the shelf dowel came out of the insertion hole.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a shelf support that can be easily attached and detached and can stably hold a shelf board for a long period of time without wobbling.

The shelf support according to the present invention is attached to the shelf dowels to be inserted into the insertion holes provided on the side walls on both sides of the storage portion and to the bottoms on both sides of the shelf board, and is fitted to the protruding portions of the shelf dowels from the side walls. In a shelf holder equipped with a dowel receiving member
The shelf dowel is composed of a dowel pin and a diameter-expanding sleeve that is fitted on the outer peripheral portion of the dowel pin, and a terminal taper portion that tapers toward the end side is provided at the end portion of the dowel pin. The tip of the dowel pin is provided with a tip taper portion whose diameter increases toward the tip side, and the diameter expansion sleeve is expanded by the end taper portion of the dowel pin.
In the dowel receiving member, a main body portion and a positioning portion are projected on a flat plate portion, and an fitting recess into which the tip tapered portion of the dowel pin is fitted is opened in the main body portion on the bottom surface of the main body portion. A pin groove is provided on the front side of the fitting recess, the shaft portion of the dowel pin is fitted into the pin groove, and the fitting recess is provided with a tapered surface that abuts on the tip tapered portion of the dowel pin. A tapered recess is provided to have
The dowel receiving member is attached by fitting the main body portion and the positioning portion into mounting holes provided at both side ends of the shelf board.
The positioning portion is projected on the center line in the longitudinal direction of the dowel receiving member so as to be located away from the main body portion, and the shelf dowel on the side wall side is fitted into the dowel receiving member. The center line coincides with the axial center of the shelf dowel .

According to the shelf receiver of the present invention, the dowel receiving member has a simple structure in which a fitting recess is provided in the main body portion, and the shelf dowel only needs to externally fit the diameter-expanding sleeve to the dowel pin. It can be easily configured. In addition, when attaching the shelf dowels to the side walls on both sides of the storage part such as a cabinet, the diameter-expanding sleeve is fitted on the outer circumference of the dowel pins, so simply insert the shelf dowels into the insertion holes provided on the side walls to insert the shelf dowels. It can be easily attached to and detached from the side wall. Further, the dowel receiving member can be easily attached without using a tool or the like by simply fitting the main body portion and the positioning portion from the lower side into the mounting holes provided at the bottom of the shelf board.
Further, since the positioning portion is projected at a position on the flat plate portion away from the main body portion, the dowel receiving member can be easily attached to the shelf plate while the angle position of the dowel receiving member with respect to the shelf plate is always constant. Can be done. Moreover, since the positioning portion is projected on the center line in the longitudinal direction of the dowel receiving member, when the dowel receiving member is attached to the shelf plate, it is appropriate to simply insert the main body portion and the positioning portion into the mounting holes. The dowel receiving member can be easily attached with the position and the angular position.
Further, when the dowel receiving member on the shelf board side is fitted to the shelf dowel on the side wall side, the center line of the dowel receiving member is fitted so as to coincide with the axial center of the shelf dowel, so that the shelf board and the dowel are fitted to the side wall surface. The receiving member is surely in a right-angled state, and the shelf board can be easily and firmly attached.

At the time of use, when the shelf board is placed on the protruding part of the shelf dowel with the dowel receiving members attached to the bottoms on both sides of the shelf board, the tapered portion of the tip of the dowel pin of the shelf dowel fits into the fitting recess of the dowel receiving member. Then, it comes into contact with the tapered surface of the tapered recess. At this time, the tapered portion at the tip of the dowel pin receives an attractive output from the tapered concave portion in the projecting direction, and the tapered portion at the end of the dowel pin acts to expand the diameter of the expansion sleeve accordingly.

Due to this diameter-expanding action, the diameter-expanding sleeve of the shelf dowel is firmly fixed in the insertion hole, and at the same time, the tip tapered portion of the dowel pin of the shelf dowel receives a pulling output from the tapered recess in the fitting recess in the pull-out direction. At that position, the dowel pin is firmly fixed to the dowel receiving member via the tapered recess and the tapered tip. At this time, since the shelf board and the side board are strongly attracted to each other via the shelf dowel and the dowel receiving member, the strength of the shelf board and the furniture as a whole can be increased. Therefore, the shelf dowel and the dowel receiving member of the shelf receiving tool can stably hold the shelf board without wobbling for a long period of time.

Furthermore, if you want to change the position of the shelf board, simply lift the shelf board in the attached state and the diameter expansion sleeve will return to the original state, so you can easily insert the shelf dowel from the insertion hole (dowel hole) without tools. It can be removed and easily inserted repeatedly into another insertion hole. Therefore, as compared with conventional screw-in type shelf dowels, it can be used repeatedly and easily without damaging the insertion hole.

Here, it is preferable that the expanded sleeve of the shelf dowel is formed by opening a slit in the axial direction of the cylindrical portion. According to this, when fitting the diameter-expanding sleeve into the outer peripheral portion of the dowel pin, the dowel pin can be easily fitted into the diameter-expanding sleeve through the slit that opens.

Further, here, a flange portion is provided at the tip of the cylindrical portion of the diameter-expanding sleeve, a flange space is provided in front of the dowel receiving member, and when the shelf dowel holds the shelf plate to which the dowel receiving member is attached, the flange is used. It is preferable that the portion enters the flange space and the front surface of the flange portion abuts on the contact surface provided on the front surface of the dowel receiving member. According to this, when the shelf board is attached, the flange portion of the enlarged diameter sleeve enters the flange space and comes into contact with the contact surface of the dowel receiving member, so that the shelf dowel is stably received without rattling. It can be held by a member.

Further, it is preferable to provide an uneven portion for preventing the expansion sleeve from coming off on the outer circumference. As a result, the uneven portion of the diameter-expanding sleeve can be held in the insertion hole and temporarily fixed by simply inserting the shelf dowel into the insertion hole of the side wall. Further, in a state where the shelf plate is attached and the diameter expansion sleeve is expanded, the shelf dowel can be more firmly fixed to the insertion hole. The enlarged-diameter sleeve having an uneven portion on the outer circumference can be easily formed by molding a synthetic resin, and the retaining function at the time of use can be improved.

According to the shelf holder of the present invention, the shelf board can be stably held for a long period of time without wobbling with a simple configuration.
