(Technology)

The present invention relates to a shelf height adjustment of the furniture, and more particularly to a shelf height adjustment to be able to freely adjust the height of the shelf mounted on the various furniture to the desired height.

(Background)

The furniture, such as built-in cabinets, bookcases, display cases, and shoe cabinets, which are used to store and store various items such as bowls, books, shoes, and ornaments, can be stored in multiple layers for efficient use of furniture space. There are many cases where more than one shelf is mounted for this purpose.

Since the position of the shelves is fixed when making furniture, the spacing between the shelves cannot be adjusted freely to accommodate the size of the item (e.g., the size of a bowl or a book) to be stored. There is a problem in that the goods can only be accommodated accordingly.

In order to solve this conventional problem, some furniture has been developed that can be adjusted to some extent between the shelves. Figure 7 is a schematic diagram of a furniture showing an example of a conventional shelf height adjustment.

As shown, the furniture 100 having a shelf is composed of a whole frame consisting of two side plates 110, the top plate 120, the bottom plate 130 and the back plate 140 arranged at predetermined intervals. , The plurality of shelves 150 are assembled at regular intervals between the two side plates 110.

Here, the height adjustment of the shelf is a side plate (up and down) spaced up and down to match the height of the article 160 of the screw holes 112 that make up a total of two, each of the two on the inner surface 111 of each side plate 110. It is formed on the inner surface 111 of the 110, the shelf support port 113 for supporting the load of the shelf 150 and the article 160 in these screw holes 112 by inserting or screwing, the same The shelf 150 consists of supporting the shelves 150 on the four fasteners 113 fastened to the level.

The user of the furniture 110, according to the size of the items held, fasten the shelf support 113 to the screw hole 112 of the appropriate position, and then put the shelf 150 on it to store items of various sizes do.

However, such a conventional shelf height adjustment, because the range that can adjust the distance between the shelves 150 is limited to the position of the screw hole 112 already fixed to the side plate 110, although the screw hole 112 Even if a plurality of layers are formed in various layers in consideration of the size of the article, there is a problem in that the distance between the shelves 150 can not be freely adjusted according to various sizes of the article held by the user.

An object of the present invention is to solve the problem of the height adjustment of the conventional shelf height adjustment as described above, to provide a shelf height adjustment of the new structure to be able to freely adjust the height of the shelf as needed will be.

As shown in the shelf height adjustment opening 1 according to the present invention, the rail 10 is fixed to the side plate (SP) of the furniture (FU) and the shelf 10 is detachably inserted fixed to the shelf (SH) And a shelf support 20 for supporting the load of the article as its basic unit.

The rail 10 has an approximately cross-section C shape having a bottom surface 11 and both side surfaces 12, and is elongated to be installed up and down along the side plate SP of the furniture FU. For example, the plastic synthetic resin Produced by injection molding.

Inside the bottom surface 11 of the rail 10, the seating grooves 13 are continuously formed at a predetermined interval (for example, 15MM) in a row. The distance between two adjacent seating grooves 13 (eg 15MM) is basically the minimum unit that can adjust the height of the shelf. Therefore, the narrower the distance between the two seating grooves 13, the finer the length adjustable height. The function of the seating groove 13 will be described later while explaining the shelf support 20.

Engaging grooves 14 are formed on both side surfaces of the rail 10 to correspond to the positions of the mounting grooves 13. That is, one seating groove 13 and the two engaging grooves 14 on both sides of the pair to support the shelf support 20.

It is not excluded that the two locking grooves 14 on both sides of the seating groove 13 are formed to face each other precisely, but one (right) locking groove 14A is slightly biased upwardly with respect to the seating groove 13. The other (left) locking groove 14B is positioned slightly biased downwardly, that is, the two locking grooves 14 are slightly staggered up and down, not exactly facing each other with one seating groove 13 therebetween. It is preferable to form so as to be in a positional relationship, in which the lower end of the right locking groove 14A is approximately coincident with the lower end of the seating recess 13, and the upper end of the left locking recess 14B is approximately coincident with the upper end of the mounting recess 13. It is preferable to make it, and it mentions later.

The length of the rail 10 may be produced in various ways depending on the size of the furniture (FU). In addition, the rail 10 may be formed to be relatively long to cover the entire height of the portion to which the shelf SH is to be mounted using one, or may be formed relatively short to cover the entire height by assembling two or more in the longitudinal direction. You may.

Like the latter, it is preferable to form the connector 30 at the end of the rail 10 in order to be able to connect and disconnect the rail 10 in its longitudinal direction. As the connector 30 which can be used, as shown in FIG. 4, the dovetail connection which formed the dovetail 31 in one end of the rail 10, and the dovetail groove 32 in the other end is preferable.

The shelf support 20 is assembled to the rail 10 so as to be detachable by one seating groove 13 and two locking grooves 14 on both sides thereof to support one of four corners of the shelf SH. . The shelf support 20 is integrally molded with, for example, plastic synthetic resin, but functionally divided into a central protrusion 21, a locking protrusion 22, and a support protrusion 23.

The center protrusion 21 is formed at one end of the shelf support 20 and is rotatably inserted into the seating groove 13 described above. Therefore, the mounting groove 13 and the center protrusion 21 may be formed in a circular shape so that the center protrusion 21 may be smoothly rotated in the seating groove 13. In addition, the center projection 21 is preferably formed to have a protruding length approximately equal to the diameter and the depth of the seating groove 13 to fit snugly into the inner diameter of the seating groove (13).

The hooking protrusions 22 formed in succession to the center protrusion 21 are slightly longer than an interval (W: rail width) between both sides 12 of the rail 10, and thus cannot be inserted into the rail width W. It is inserted into the LL and the rail width (W) and has a cross-sectional rectangular shape having a longitudinal length (LS) that can be accommodated over the two locking grooves 14, preferably the protruding length of the center projection (21) It has a degree that is fitted to fit the seating groove (13).

Therefore, in the state in which the shelf support 20 is positioned horizontally, the latching projections 22 cannot be inserted into the rail width W because they are caught on both sides 12, but in the vertical position, the shelf projection 20 is inserted into the rail width W. (A in FIG. 3). In addition, when the shelf support 20 is rotated in the state in which the locking protrusion 22 is inserted into the rail width W, the locking protrusion 22 basically has a horizontal length larger than the rail width W so that the rail 10 Although it is not caught and rotated on both sides 12 of the), in the state in which the center projection 21 is inserted into the seating groove 13, the locking groove 14 is present on both sides of the seating groove 13, so that the locking protrusion 22 The shelf support 20 can be rotated without being caught by both sides 12 of the rail 10 (FIG. 3B).

As a result, the locking projection 22 is positioned vertically and the locking projection 22 is rotated in the state in which the center projection 21 is inserted into the seating groove 13 (A in FIG. 3). The shelf support 20 is secured to the rail 10 by being accommodated over the locking groove 14 (B of FIG. 3), and the shelf support 20 is rotated in the vertical direction again. It can be separated from the rail (10).

In addition, as shown in Figure 3, the bottom of the right locking groove (14A) to match the bottom of the seating groove 13, and the top of the left locking groove (14B) to approximately match the top of the seating groove (13) When the two locking grooves 14 are slightly staggered up and down with respect to the seating groove 13, the shelf support 20 is fixed to the rail 10 while being rotated 90 degrees clockwise and 90 degrees counterclockwise. As it is rotated, it is separated from the rail 10.

That is, the right locking groove 14A is biased upward and the left locking groove 14B is biased downward when the shelf holder 20 is rotated clockwise from the state A of FIG. 3 to the state of B of FIG. Therefore, both ends of the locking projection 22 are introduced into the locking groove 14, respectively, the shelf support 20 is rotated, but the opposite direction of rotation of both ends of the locking projection 22 is both sides 12 of the rail (10) ) Can not be rotated, and the rotation of the shelf support 20 is caught at both ends of the right locking groove 14A and the top of the left locking groove 14B, respectively, as shown in FIG. Until it is rotated up to 90 degrees. Considering the rotation of the locking protrusion 22, both ends of the locking protrusion 22 are preferably formed in an arc shape as shown in FIG.

Supporting protrusions 23 are formed integrally with the locking protrusions 22, and the supporting protrusions 23 are provided at both sides of the rails 10 in a state in which the shelf support holes 20 are assembled to the rails 10. (12) Abut with the top. Eventually, the shelf support 20 is inserted into the seating groove 13 of the center projection 21, the insertion of the locking projection 22 into the two locking grooves 14, and the abutment of both sides of the rail 12 of the support protrusion 23. Will be assembled and fixed to the rail 10 by mutual cooperation of the.

At the upper end of both sides of the rail 12, a widening portion 15 is extended to the outside, thereby increasing the contact area between the both sides 12 of the rail 10 and the support protrusion 23, thereby increasing the area of the shelf support 20. It is desirable to increase the assembly stability.

As described above, the minimum length of the height-adjustable shelf (SH) is the distance between two adjacent seating grooves 13, the height of the shelf is not possible to the length less than. Therefore, the micro-adjustment piece 40 may be mounted to the shelf support 20 as shown in FIG. 5 so that the shelf height can be adjusted to be less than or equal to the gap between the two seating grooves 13.

The micro-adjustment piece 40 is mounted to the recessed part 24 formed in the support protrusion 23, and the shaft part 41 is rotatably inserted into the bearing 25 formed in the recessed part 24, the shaft part ( 41 is formed to protrude, but may be composed of a polyhedral support portion 42 having various heights, and a driver groove 43 formed at both ends of the shaft portion 41. The micro adjustment piece 40 is mounted to the support protrusion 23 of the shelf support 20 by forcibly inserting the shaft portion 41 into the bearing 25.

When the driver inserts the driver into the driver groove 43 and rotates the shaft part 41 according to the configuration of the fine adjustment piece 40, the height of the shelf SH which is raised thereon is changed while the protrusion height toward the upper side of the support part 42 changes. The height can be adjusted more finely.

Shelf height adjustment device 1 of the present invention as described above, as shown in Figure 6, the four rails 10 on the inner side and outer side of the two side plates (SP) facing the furniture (FU) in the longitudinal direction The shelf SH is supported by fixing and inserting the shelf support 20 at the same height by placing the shelf support 20 at the same height on each rail 10 and placing the shelf SH on the four shelf support 20. do.

As a method of fixing the rail 10 to the side plate SP, a groove GR for inserting the rail 10 in the vertical direction of the side plate SP is formed, and the rail 10 is formed in the groove GR. Insertion and adhesive bonding are preferred. At this time, it is preferable that the extension part 15 is positioned on the same plane as the side plate SP.

If you want to adjust the height of the shelf (SH), put down the raised shelf (SH) and then remove the four shelf support holes (20) from the rail (10) and then set the appropriate height again to the rail (10) After that, put the shelf (SH) again. At this time, the fine horizontal of the shelf (SH) can be adjusted by operating the fine control piece (40).

According to the shelf height adjustment device (1) according to the present invention described above, the height of the shelf can be freely adjusted as needed by a simple operation of moving the shelf support port 20 with respect to the rail (10).
