Description

[Technical Field]

[0001] The present invention relates to a slip prevention member that prevents items stored on a shelf from falling. [Background technology]

[0002] Items stored or displayed on shelves may fall due to unexpected vibrations or the like. For this reason, Patent Document 1 discloses a device that forms multiple brackets so that they abut against the side panels and the shelf, and attaches the brackets to prevent items from falling from the shelf. These brackets must be fixed to the side panels with screws or the like, and covers must also be attached to the brackets, resulting in a large number of parts. In recent years, open shelves that do not use side panels on either side of the shelf have become more common, but because such open shelves do not use side panels, it has sometimes been impossible to attach the anti-tip brackets described in Patent Document 1 to the side panels.

[0003] In addition, the invention of Patent Document 2 allows the anti-tip member to be formed by screwing a pipe fixture into the screw hole of the display stand and inserting the pipe into the insertion hole, rather than attaching it to the side panel. However, the invention of Patent Document 2 has the problem that it is difficult to position it to fit the pipe because it is attached to the installation surface. Open shelves are often installed at home rather than by a business as in DIY projects, so there has been a demand for an anti-tip bracket that allows for easy positioning and installation.

[0004] [Patent Document 1] Patent No. 6451020 [Patent Document 2] Japanese Patent Application Publication No. 9-51824 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above problems, the present invention provides an anti-fall member that is easy to install by facilitating the positioning of the bracket and the attachment of the rod member. [Means for solving the problem]

[0006] In order to solve the above problem, the anti-slip device of the present invention is configured to be attachable to an open shelf board having an open side, and includes at least a corner bracket and a rod member, The angle bracket has a first insertion hole for inserting one of the rod members extending in one direction and a second insertion hole for inserting the other of the rod members extending in a direction perpendicular to the one direction, and an angle bracket body having an installation bottom surface; a leg portion that hangs downward from the rear side of the installation bottom surface and has two lower walls whose width directions are perpendicular to each other; The angle bracket is characterized by having a forward protruding portion that protrudes forward from the lower end of the angle bracket body and has a fixing hole.

[0007] Furthermore, it is preferable that the rear side edges of the insertion surfaces of the first insertion hole and the second insertion hole of the angle bracket are located forward of the lower walls of the leg portions of the angle bracket.

[0008] The rear side of the angle bracket body has an inclined surface that slopes forward, In a side view, it is preferable that the upper end position of the inclined surface is located forward of the contact position where the two lower walls of the leg portions of the angle bracket come into contact.

[0009] The device further includes a flat bracket provided between the plurality of angle brackets, The flat bracket includes a flat bracket body having a first insertion hole and a second insertion hole into which two rod members extending laterally are inserted, and having an installation bottom surface; a leg portion extending downward from the rear side of the installation bottom surface and having a lower wall hanging down from the installation bottom surface; It is preferable that the flat bracket body has a forward protrusion extending forward from a lower end thereof and having a fixing hole. [Effects of the Invention]

[0010] According to the invention described in claim 1, the shelf has two lower walls that are perpendicular to the legs, making it easy to position the shelf by aligning the legs with the corners of the open shelf. Furthermore, the legs can be easily fixed with screws in the fixing holes of the forward protrusions. By fixing a corner bracket to one corner and attaching a rod member to the insertion hole, it is possible to easily attach anti-slip members by positioning and fixing the corner brackets in the same way to the other corners.

[0011] According to the invention described in claim 2, when the open shelf is positioned by the lower wall of the corner bracket, the rod is positioned near the edge of the open shelf, or more precisely, slightly inside the edge. By configuring it in this way, when the corner bracket is positioned at the corner of the open shelf, the rod can be easily positioned near the edge of the open shelf, making it easy to attach the anti-slip member.

[0012] According to the invention described in claim 3, the upper end portion of the rear inclined surface of the corner bracket is located forward of the contact point where it meets the lower wall, so when the anti-tip member is placed on the open shelf, the upper portion of the corner bracket is located further inward on the open shelf than the corner portion, preventing the user from accidentally coming into contact with the corner bracket and getting injured.

[0013] According to the invention described in claim 4, by providing flat brackets between the angle brackets, even if the rod members are not long enough to join the angle brackets together, the flat brackets make it possible to attach anti-slip members to the shelf boards.The flat brackets are also easy to position with the legs and can be easily fixed with screws.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The anti-fall member of the present invention will be described with reference to the drawings. Note that the following description is of one embodiment, and the present invention is not limited thereto. In this description, the front side where the forward protrusion of the angle bracket 3 described below is located will be referred to as the "front," and the back side where the legs are located will be referred to as the "rear." The front and back in front view will be referred to as the "front-to-rear direction," the left and right as the "width direction," and the top and bottom as the "height direction."

[0016] As shown in Figures 1 and 2, the anti-slip member 1 is intended to be attached to an approximately square open shelf 10, and consists of a corner bracket 3 to be placed at the corner portion 10a of the open shelf 10, and a rod member 4 to join the corner brackets 3 together; if necessary, a flat bracket 5 to be placed at the middle edge portion 10b of the open shelf 10 can also be used.

[0017] The open shelf 10 will now be described. The open shelf 10 is a shelf with a roughly rectangular wooden board as the top board, as shown in Figures 3(a) and (b), and has no boards attached to at least the side faces, leaving the sides open. As shown in Figure 3(a), the open shelf 10 can be supported from below by L-shaped metal fittings 11, 11. These L-shaped metal fittings 11, 11 are fixed directly to the wall surface by screws 12, 12.

[0018] 3(b), the open shelves 10 may be stacked above an upper open shelf 10 that serves as a top plate to form a group of vertically continuous shelves. In this case, multiple open shelves 10 are supported by square frames 14 that are open inside, and specifically, the square frames 14 are connected at the end faces of the open shelves 10 facing the wall to the end faces on the opposite side (front side) from the wall, and the square frames 14 are fixed directly to the wall with screws 12. In addition, the open shelves 10 may be attached in a cantilevered manner to a rail-shaped installation member, and the installation form of these open shelves 10 is not limited thereto.

[0019] The open shelf 10 shown above does not have side panels on at least the left and right sides, leaving the sides open, particularly around the corners 10a, 10a on the front side and the middle edges 10b, 10b on the front and side sides. These open shelves 10 are now often assembled and installed at home by DIY. This invention provides a slip-stop member 1 for such an open shelf 10 that can be easily positioned and installed by anyone other than a construction company.

[0020] As shown in Figures 4, 5, 6 and 7, the corner bracket 3, which is an element of the anti-slip member 1 of this embodiment, is a rectangular column-shaped member that is placed at the corner portion 10a of the open shelf 10 (see Figures 1 and 2), and comprises a corner bracket main body 31, a forward protrusion 32 that protrudes forward, and a leg portion 33 that extends from the rear lower end of the corner bracket main body 31.

[0021] The angle bracket body 31 of this embodiment is a rectangular columnar member that tapers from the bottom to the top. In a front view from the front protruding portion 32 (see FIG. 4(b)), it has a curved cutout surface 31a cut out inward in the center, and rod support surfaces 31b, 31b that extend from both side edges of the curved cutout surface 31a and tilt rearward in the width direction.

[0022] The rear side (back side) of the angle bracket body 31 has a first inclined surface 31c in the center, which widens from the bottom to the top and slopes forward, and second inclined surfaces 31d, 31d on both sides of the first inclined surface 31c, which narrow from the bottom to the top and slope forward in the width direction. The first inclined surface 31c has an inverted triangular shape, and the two second inclined surfaces 31d, 31d join at the bottom to form a rear end 31e. The two second inclined surfaces 31d, 31d are in contact with the two rod support surfaces 31b, 31b at their front edges.

[0023] The angle bracket body 31 of this embodiment is a rectangular columnar member having a relatively large forward inclination at the rear side and a gentle backward inclination at the front side, resulting in an overall tapered shape. In plan view, the upper flat surface 31f is formed into a substantially hexagonal shape by the front curved cutout surface 31a, the two rod support surfaces 31b, 31b, the first inclined surface 31c, and the upper edges of the two second inclined surfaces 31d, 31d.

[0024] The first and second insertion holes 34a, 34b arranged in the two rod support surfaces 31b, 31b are generally rectangular holes that are long in the vertical direction, and are provided in two locations symmetrically above the rod support surfaces 31b, 31b (see FIG. 4(b)). As shown in FIG. 6(a), the first and second insertion holes 34a, 34b are provided with resin frame members 20 that cover the inner walls of the holes. By abutting against the inner walls of the first and second insertion holes 34a, 34b, gaps between the first and second insertion holes 34a, 34b and the rod members 4 are eliminated, preventing rattling. In this embodiment, the first and second insertion holes 34a, 34b are rectangular in shape to correspond to the rod member 4 having a rectangular cross section. However, this is not limited to this, and the first and second insertion holes 34a, 34b may be elliptical in shape if the rod member 4 is elliptical.

[0025] The insertion surfaces 20a of the first and second insertion holes 34a, 34b refer to the opening end surfaces through which the rods 4, 4 are actually inserted. In this embodiment, the frame member 20 is used, so the insertion surfaces 20a are the portions surrounded by the frame member. The frame member 20 creates an edge (opening edge) that is slightly smaller than the periphery of the first and second insertion holes 34a, 34b. A rear edge P extending vertically at the rear side of this opening edge is located forward of the lower wall 33b of the leg 33 (described below). Specifically, as shown in FIG. 6(b), the rear edge P of the insertion surface 20a is located forward of the imaginary line X-X indicated by a dashed line extending vertically upward beyond the lower wall 33b. This ensures that when the open shelf is positioned by the lower wall 33b, the rods 4, 4 are located near the edge of the open shelf 10—more precisely, slightly inside the edge—making it easier to position the anti-slip member.

[0026] The rod members 4, 4 inserted and supported in the first insertion hole 34a and the second insertion hole 34b into which the frame members 20, 20 are inserted are oriented perpendicular to each other. Specifically, they are perpendicular to each other so that the positions where two imaginary extension lines ZZ, which are extended by dashed lines from the cross-sectional centers of the rod members 4, 4, intersect are right angles (see FIG. 7(a)).

[0027] The forward protrusion 32 protrudes further forward from the curved cutout surface 31a and the two rod support surfaces 31b, the lower end portions of 31b, which form the front side of the angle bracket main body 31, and has an installation bottom surface 35 that continues from the angle bracket main body 31 and presses against the upper plane of the open shelf 10. The forward protrusion 32 gradually narrows towards the tip, has a curved tip, and has a fixing hole 32a in the center. The angle bracket 3 can be fixed to the open shelf 10 by screwing a screw B into the fixing hole 32a.

[0028] The legs 33 hang downward from the lower ends of the two second inclined surfaces 31d, 31d that form the rear side of the angle bracket main body 31, and when viewed from the bottom, hang downward from the rear side of the installation bottom surface 35. Specifically, the rear side is folded inward from the second inclined surfaces 31d, 31d to form two tapered surfaces 33a, 33a, and the front side forms two lower walls 33b, 33b that hang downward from the rear side of the installation bottom surface 35 that forms the bottom surface of the angle bracket main body 31 and the forward protrusion 32.

[0029] The leg 33 is formed with a predetermined thickness between the tapered surface 33a and the lower wall 33b. The two lower walls 33b of the leg 33 extend in width directions perpendicular to each other and meet at a contact position 33c in the center of the width direction. Specifically, the lower walls 33b are perpendicular to each other so that the contact position where two imaginary extension lines YY, which are extended in the width direction of the lower walls 33b by dashed dotted lines, intersect is a right angle (see FIG. 7(b)).

[0030] Because the angle bracket 3 has the above-described configuration, it can be placed at the corner 10a of the open shelf 10, and the rod 4 can be attached in a perpendicular direction. That is, because the width directions of the two lower walls 33b, 33b of the leg 33 are perpendicular to each other, positioning can be easily achieved by placing the angle bracket 3 so that the wall surface of the corner 10a is aligned with the lower walls 33b, 33b, and the upper plane of the corner 10a of the open shelf is aligned with the installation bottom surface 35 (see Figure 5(d)). Also, as described above, the two rods 4, 4 are aligned in directions perpendicular to each other, and the rods 4, 4 are positioned near the edge of the open shelf 10. This allows the anti-slip member 1 to be easily positioned simply by placing the angle bracket 3 at the corner.

[0031] Furthermore, in this embodiment, the first inclined surface 31c and the two second inclined surfaces 31d on the rear side of the angle bracket main body 31 have their upper end portions (rearward-facing portions of the upper flat surface 31f) inclined forward as described above, and are located forward of the contact position 33c, shown by the dashed line in the side view of Figure 4(c), where the two lower walls of the legs meet. Specifically, the upper end portions are located forward of the imaginary extension line W, which is an alternate long and short dashed line extending upward from the contact position 33c. As a result, when the anti-slip device 1 is placed on the open shelf 10, the upper portion of the angle bracket 3 is located further inward than the corner portion 10a of the open shelf 10, preventing a user from accidentally coming into contact with the angle bracket 3 and being injured.

[0032] The curved cutout surface 31a of the angle bracket body 31 prevents the screw tightening tool from interfering with the angle bracket body 31 when attaching the screw to the fixing hole 32a of the forward protrusion 32, thereby preventing part of the angle bracket 3 from being scraped off.

[0033] The first inclined surface 31c, the second inclined surface 31d and the tapered surface 33a of the angle bracket body 31 are inclined inward so as not to interfere with components arranged around the open shelf board 10, and are also not angular to ensure safety when a user comes into contact with them.

[0034] Next, we will explain the flat bracket 5. The flat bracket 5, which is one of the anti-slip members 1 of this embodiment, is a square pillar-shaped member that is placed on the open shelf 10 between the two angle brackets 3, 3, and includes a flat bracket main body 51, a forward protruding portion 52 that protrudes forward, and a leg portion 53 that extends from the rear of the lower end of the flat bracket main body 51.

[0035] The flat bracket body 51 of this embodiment is a rectangular pillar-shaped member tapering from the bottom to the top on the back side, and has a front surface 51a on the front protruding portion 52 side, two side surfaces 51b, 51b, and a rear surface 51c. Two insertion holes 54a, 54b for attaching the rod member 4 are formed in the two side surfaces 51b, 51b, respectively, and are open in opposite directions. As with the angle bracket 3, the insertion holes 54a, 54b are provided with frame members 20.

[0036] The leg portion 53 protrudes downward from the lower end of the rear surface 51c of the flat bracket main body 51. Specifically, the leg portion 53 is folded inward from the rear surface 51c to form a tapered surface 53a, and the rear end of the installation bottom surface 55, which is the back surface of the flat bracket main body 51 and the forward protruding portion 52, forms a lower wall 53b that extends downward.

[0037] The leg 53 has a predetermined thickness between the tapered surface 53a and the lower wall 53b. The leg 53 has a linear shape when viewed from the bottom, so that it can abut against the side surface of the corner of the open shelf board 10.

[0038] Next, as shown in FIGS. 9, 10, 11 and 12, a method for assembling the anti-slip member 1 by attaching the angle bracket 3 and the rod member 4 to the open shelf board 10 will be described.

[0039] First, the leg 33 of the corner bracket 3 is abutted against one corner 10a of the open shelf 10 (see Figure 9). At this time, the lower wall 33b of the leg 33 is bent at a right angle, making it easy to position it at the corner 10a of the open shelf 10. Furthermore, the corner bracket 3 has a forward protrusion 32, so the installation bottom surface 35 presses against the upper flat surface of the open shelf 10, and the aforementioned leg 33 presses against the side of the corner 10a of the open shelf 10, making it easy to position it by abutting multiple surfaces with one bracket. Furthermore, the corner bracket 3 can be easily fixed to the open shelf 10 by simply fastening it with a screw B into the fixing hole 32b of the forward protrusion 32.

[0040] Next, after fixing one of the corner brackets 3, insert the rod member 4 into the insertion hole 34 of the other fixed corner bracket 3, while similarly positioning and fixing the other corner bracket 3 to the other corner portion 10a of the open shelf 10. At this time, when positioning the other corner bracket 3, insert the rod member 4 into the insertion hole 34 of one of the corner brackets 3. This completes the anti-slip member 1 (see Figure 10). At this point, the rod member 4 may be cut to adjust its length.

[0041] Furthermore, if one side of the open shelf 10 is long and the rod member 4 does not reach from one angle bracket 3 to the opposing angle bracket 3, a flat bracket 5 may be placed between the angle brackets 3 and used as a relay point for the angle brackets 3. That is, the angle bracket 3 is first placed and fixed at the corner portion 10a of the open shelf 10 (see Figure 11), and then the flat bracket 5 is placed at the middle edge portion 10b of the open shelf 10 while inserting the rod member 4 into the insertion hole 54 of the flat bracket 5 (see Figure 12).

[0042] When fixing the legs 53 of the flat bracket 5 to the open shelf 10, the legs 53 come into contact with the edge of the open shelf 10, facilitating positioning, just like the angle bracket 3. Furthermore, the flat bracket 5 has a forward protrusion 52, so the installation bottom surface 55 presses against the upper surface of the open shelf 10, and the aforementioned legs 53 press against the side, making positioning easy as one bracket comes into contact with multiple surfaces. Furthermore, the flat bracket 5 can be easily fixed to the open shelf 10 simply by fastening it with a screw in the fixing holes 52a of the forward protrusion 52.

[0043] This embodiment has been described above, but is not limited to the above. For example, in a case where an open shelf 10 is provided on a wall surface as shown in Figure 3(a), since it is not necessary to provide corner brackets 3 at the four corners, corner brackets 3 may be provided at the front corners of the open shelf 10, and the corner brackets 3 may be joined together with rod members 4, and flat brackets 5 may be placed on the wall surface.
