Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner shelf structure provided in a corner portion of a room or the like, and more particularly to a corner shelf mounting / holding structure. In this specification, the room is not limited to a room such as a house or an office,
A space defined by at least a wall surface, including an internal space such as a garage, a warehouse, and a factory, is a general term.

[0002]

2. Description of the Related Art A shelf is mounted in a corner (corner) of a room or the like, or a rack or cabinet having a shape suitable for the corner is installed, and a corner space is decorated with a desired ornament and used effectively. It is possible. But,
There is a case where the space cannot be enjoyed with an installation type such as a rack or a cabinet. That is, when it is desired to decorate an ornament or the like at an arbitrary space position in the height direction of a corner in a room, it is impossible with a rack or cabinet of an installation type.

[0003]

In such a case, it is conceivable to attach a shelf at an arbitrary height position of the corner. Conventionally, as shown in FIG. 11, for example, brackets 200, 200 are fixed at the same height position on the left and right wall surfaces 100, 100 of a corner portion 400, and a shelf plate 300 is held via the brackets 200, 200 to mount a shelf at a corner portion in a room or the like. What was provided is generally known.

However, when a shelf is to be provided at an arbitrary position in a corner portion of a room or the like according to the prior art shown in the drawing, it is necessary to position the left and right brackets 200 and 200 so that they are at the same height position (level). In addition, the positioning was very troublesome and the mounting work was also troublesome.

[0005] Further, since the arrangement of the shelves cannot be freely and easily changed due to the above-described configuration, it is necessary to use extra nerves for initial positioning, and to arrange the shelves once in a predetermined position. Then, when the position is changed next time, the brackets 200, 200 must be removed again, the predetermined position must be determined again, and the mounting work of the brackets 200, 200 and the shelf 300 must be repeated, which is troublesome.

Further, since holes are formed in the wall surface by nails or the like used for fixing the bracket 200, especially in a rental house or the like, it is likely that changing the arrangement position frequently will result in the wall surface being full of holes. This is undesirable in the prior art.

[0007] Further, as another technique, a frame body which is configured to be expandable and which firmly fixes and fixes the left and right side surfaces to a mounting wall surface, a shelf board fitted into the frame body, There is known a shelf board structure including a pressing rod configured to be extendable and extendable between right and left frame portions, but this technique has the same problem as described above.

That is, first, the frame body is set to a desired expanded state in accordance with the corner angle of the mounting corner, and the left and right side surfaces of the frame body are fixed to the initially set mounting position of the corner wall surface. If it does, it is difficult to remove it, and if it is forcibly removed, the adhesive surface provided on the side surface of the frame may come off, making it impossible to attach it again.

In addition, the right and left frames are pressed against the wall surface by extending and extending the pressing rod between the left and right side surfaces. The pressing rod, which is a separate member, is provided between the left and right side surfaces of the frame body. The extension work was difficult and troublesome.

In addition, the frame, the pressing rod and the shelf are separated from each other, and the work of fixing the frame to the corner wall, the pressing of the left and right frames by the pressing rod, and the work of placing the shelf are performed respectively. They had to be performed separately, which was troublesome and required too much work time.

Further, the conventional corner shelf structure has the following problem. That is, in the corner shelf plate structure generally known including the above-mentioned conventional technology, the wall surface corner to be attached has a predetermined angle, for example, 90 degrees.
It is generally designed and manufactured on the premise of the degree, and it is not possible to correct the angle of the mounting and fixing surface to match the target wall surface.

However, there are many errors in the wall corner angle depending on the building skeleton, and the wall corner may not always be 90 degrees.

Therefore, in such a case, the fixed surface (fixed surface) and the target wall surface do not become parallel to each other, so that the adhesion between the two surfaces is reduced, and the shelf plate can be securely and firmly attached to the wall surface corner. In addition to the inconvenience that the mounting condition is unstable and the object cannot be put on the shelves at the bottom because of the difficulty, the worst case (when the parallelism between the shelf fixing surface and the target wall surface is extremely low, etc.) In (2), there is a possibility that a situation where a shelf board cannot be attached to a wall corner may be caused.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to easily and reliably perform positioning and mounting only by rotating a single operation handle. It is an object of the present invention to provide a corner shelf structure which can be obtained and can be firmly held at a corner portion.

Further, even if a slight error occurs in the corner of the wall surface to be mounted, the present invention can stably and firmly mount and install according to the error by correcting the angle of the fixing portion, and provide a stable and strong mounting. It is also intended to be.

[0016]

The technical means achieved by the present invention to achieve the above object is to provide a shelf board having non-parallel left and right contact sides crossing on an extension line, and a back face of the shelf board. And an operation unit arranged so as to be orthogonal to a line that equally divides a corner portion sandwiched between the non-parallel left and right contact sides of the shelf plate, and swingable at both ends of the operation unit, respectively. The operating part is coaxially arranged so as to be orthogonal to a line that equally divides a corner part sandwiched between the non-parallel left and right contact sides of the shelf board. Rotating shaft,
A bevel gear provided at each of the opposite ends of the left and right rotary shafts, a single operating handle having a bevel gear that meshes with the respective bevel gears and transmits a rotation operation, and a play of the respective rotary shafts. The fixing part is arranged on the end side, and is constituted by a forward and backward moving member that causes the fixing part to protrude and retract coaxially from the respective non-parallel abutting edges of the shelf board, and the fixing part is via a fixing part angle correcting part. A fixed portion main body is connected to the forward / reverse member so as to be able to swing left and right, and one or two or more fixing projections provided on an end face of the main body.

Also, an outer box for loosely inserting the free end side of the rotary shaft, and slidably disposed in the outer box, and at the forward limit position, its tip abuts on the inner box bottom surface to provide a stopper function. A slide cylinder to be played and a screw part provided integrally on the inner bottom surface of the slide cylinder and provided on the outer periphery of the free end side of the rotary shaft are screwed together to convert the rotation operation of the rotary shaft into the forward and backward movement of the slide cylinder. An operation conversion section;
The forward / backward moving member is constituted by the elastic member disposed between the operation conversion unit and the inner bottom surface on the distal end side of the outer box.

In the present embodiment, for example, the outer boxes 16, 16 are provided with an inner wall surface 5b of the operation section casing 5a having a rectangular cross section.
Is formed in a rectangular box having a rectangular cross section slightly narrower than the casing 5 so that the outer wall surfaces 16a, 16a can slide and the entire outer box cannot rotate.

Then, through holes 17 are formed in the outer wall surfaces 16b on the rear end side, and a slide cylinder 18 and an elastic member 21 are disposed inside the outer box 16.
In the figure, reference numeral 38 denotes a spacer interposed between the operation conversion unit 20 and the elastic member 21.

In this embodiment, the outer box 16 is formed to have a rectangular cross section slightly narrower than the operation section casing 5a, but without rotating inside the operation section casing 5a. The structure is not limited to the above shape as long as the structure can move forward and backward. For example, a ridge (continuous in the forward and backward direction) is provided on one of the inner wall surface 5b and the outer case outer wall surface 16a of the operation unit casing 5a. Along with
The other may be provided with a long groove for slidably fitting the ridge, and can be appropriately selected and changed within the scope of the present invention. With such a configuration in which the ridges and the long grooves are provided, the outer box may have an arbitrary cylindrical shape such as a cylindrical shape.

In the present embodiment, for example, the slide cylinders 18 are formed in the outer box 1 having a rectangular box shape having a rectangular cross section.

With the above configuration, the screw portions 8, 8 of the rotary shafts 6, 6 are inserted into the insertion holes 17, 1 of the outer boxes 16, 16, respectively.
7. The screw portions 8, 8 are screwed into the screw holes 20a, 20a of the operation conversion portions 20, 20, through the insertion holes 19, 19 of the slide cylinders 18, 18, so that the screw portions 8, 8 are rotated by the rotating shafts 6, 6. The screw holes 20a,
The rotary cylinder 20 makes a rotary motion within the rotary motion 20a, and the rotary motion causes the slide cylinders 18 to move forward and backward in the directions indicated by arrows in FIG.

The operation conversion unit 20 includes a slide cylinder 18.
And is integrally fixed to the slide cylinder inner bottom surface 18b, or alternatively, is formed integrally with the slide cylinder inner bottom surface 18b.
The screw hole 20a may be directly formed without providing the insertion hole 19 in the through hole. Particularly, if the rotation operation of the rotary shaft 6 can be converted into the forward and backward movement of the slide cylinder 18, the structure is particularly preferable. The structure is not limited.

In this embodiment, the slide cylinder 18 is formed to have a rectangular cross section slightly narrower than the outer box 16, but the present invention is not limited to this shape. Any structure can be used as long as it can move forward and backward without rotating the inside of the box 16. For example, a ridge is provided on one of the inner wall surface 16 e of the outer box and the outer wall surface 18 a of the slide cylinder, and the ridge is slid on the other. It is also possible to provide a long groove to be fitted as much as possible, and it can be appropriately changed within the scope of the present invention. With such a configuration, the slide cylinder may have an arbitrary cylindrical shape such as a cylindrical shape.

In the present embodiment, the forward movement of the slide cylinder 18 is stopped by the tip of the slide cylinder 18 abutting against the inner bottom surface of the outer box 16. Etc. can be prevented.

Also, a mounting part 2 for the fixed part angle correcting part.
The inclined tip surfaces 23, 23 of the non-parallel two sides 2, 2 of the shelf 1 are respectively formed in the same inclined shape.

In the present embodiment, the elastic member 21 uses a coil spring, and the coil spring 21 is at least in a state where it is not urged at least.
8 is longer than the internal space, and is pressed against the elastic force of the slide cylinder 18 by the forward operation of the slide cylinder 18, so that the fixed portion 30 is always in the pushed state. The elastic member may use rubber or a leaf spring instead of the coil spring.

The fixed part angle correcting part 25 includes a forward and backward moving part 15,
The fixing portions 30 and 30 are connected and held so as to be able to swing right and left at the tip of the fifteen. With this configuration, when the fixing surface of the shelf 1 and the wall surface W to be attached are not parallel, By correcting the angle of the fixing surface, it is possible to obtain the parallelism with the mounting target wall surface W.

The fixed portion angle correcting portion 25 is a ball 26 having a desired diameter.
And a connecting rod 27 raised from the outer peripheral surface of the ball 26. For example, the inclined front end surfaces 23, 23 of the mounting portions 22, 22, for fixing the angle of the fixed portion of the forward and backward moving portions 15, 15, are roughly described. The ball 26 is inserted into the concave portion 24 provided at the center position, and the connecting rod 27 is inserted into the small hole 40 provided on the facing surface 31a of the fixing portion main body 31 of the fixing portion 30 so as to be connected. The recess 24 has a space in which the ball 26 can freely roll while being held at a predetermined position,
On the other hand, the connecting rod 27 is inserted and fixed in the small hole 40 of the fixing part 30.

As a method of holding the ball 26 in the recess 24 by the fixed portion angle correcting portion 25, for example, as shown in FIG. A hemispherical hole 22a capable of accommodating only the lower part from the diameter position was formed, and a hole 36b large enough to cover the remaining part of the ball 26 was provided from above with the ball 26 arranged in the hole. Cover the lid 36. Therefore, according to the illustrated example, the inclined distal end surface 23 of the attachment portion 22 for the fixed portion angle correcting portion is constituted by the distal end surface 36a of the lid portion 36 described above. It should be noted that the illustrated example is merely one embodiment and is not limited, and modifications within the scope of the present invention can be arbitrarily made.

A gap 39 is formed between the front end surface of the inclined front end surface 23 of the forward-reverse portion 15 and the fixed portion 30, and the gap 39 is specifically about 2 mm to 3 mm. But,
There is no particular limitation, and the gap 39 can be changed as appropriate within the scope of the present invention. If the gap 39 is widened, the swing range of the fixed portion 30 is widened, and if the gap 39 is narrowed, the swing range of the fixed portion 30 is small. The swing range becomes smaller.

FIGS. 8 and 9 show another example of the configuration of the fixed portion angle correcting portion 25. FIG. 8 is a schematic diagram, and FIG. 9 is a sectional view taken along line AA of FIG. That is, in the illustrated embodiment, the distal end portion 15a of the forward / rearward advance portion 15 is formed into a fixed portion angle correcting portion 25 by a structure including arms 28, 28 sandwiching the fixed portion main body 31 from above and below. Upper and lower arms 2
The structure is such that the fixing portion 30 can be swung right and left through the connecting pins 29 over the fixing portions 8 and 28 and the fixing portion main body 31.
Even in the present embodiment, since there is no change in the swinging motion of the fixing portion 30 and the fixing action to the wall surface W, the description is omitted here.

The fixing portions 30, 30 are fixed angle correcting portions 2
5, a fixing portion main body 31 provided to be able to swing left and right at the distal end of the forward and backward moving portions 15, 15, fixed projections 32, 32 projecting from the distal end surface of the main body 31, and the projections 32, 32.
And elastic members (coil springs) 33, 33 arranged in a protruding manner in the same manner as described above, and a blind portion 34 supported via the elastic members 33, 33 and capable of at least covering the fixing projections 32, 32. The fixing projection 3
The shelves 2 and 32 are stuck to the left and right wall surfaces W and W of the corner portion C in a room or the like (the state where they are stuck and fixed), and the shelf board 1 is attached and held.

The blind portion 34 is a thin flat plate longer than the fixing portion main body 31, and is provided at a position opposed to the fixing projections 32, 32 in the form of a slender elliptical fixing projection from which the projections 32, 32 can protrude, respectively. Protrusion holes 35 are provided.

One end of the elastic member 33 is connected to the forward / reverse
The other ends are provided to be fixed to the fixing portion 30, respectively, and the fixing protrusions 32, 32 are made to project from the fixing protrusions 32, 32 when not pressed, so that the fixing protrusions 32, 32 are not exposed. Note that the elastic member 33 is not limited to a coil spring as in the present embodiment, but can be changed to another elastic member within the scope of the present invention, such as a soft resin rich in plate spring elasticity.

In the present embodiment, the fixing projections 32 are provided with two stud-shaped ones at an interval.
One or three or more such stud-shaped protrusions may be provided, and the present invention is not limited to this and is arbitrary within the scope of the present invention.

Here, a method of attaching the corner shelf structure according to the present embodiment will be described. In the illustrated example, the corner portions C of the mounting target walls W, W are not slightly at 90 degrees (slightly wider than 90 degrees), and the corner portions 4 are 90 degrees.
A description will be given of a case where the fixed portion 30 of the newly designed shelf 1 and the wall surface W to be attached are not parallel (see FIG. 5).

First, a shelf arrangement position is selected from an arbitrary position in the height direction of a corner portion C such as a room, and the corner portion 4 is applied to the corner portion C position (the corner portion 4 in the illustrated example). Is cut into a square shape.)

The corner portion C of the mounting target wall W
Is 90 degrees, the corner portion 4 can be applied to the corner portion C, and the left and right contact sides 2 and 2 of the shelf 1 can contact the left and right wall surfaces W and W, respectively.

Next, when the single operation handle 11 is rotated, the rotational movement of the bevel gear 12 attached integrally with the handle 11 is transmitted to the respective bevel gears 10, 10 of the rotary shafts 6, 6. And the bevel gears 10, 10 rotate in different directions, respectively, and the rotation moves through the forward and backward moving portions 15, 15 via the reversely threaded screw portions 8, 8 at the tips of the respective rotating shafts 10, 10.
Is transmitted to

The rotation operation of the rotary shaft is
The operation conversion part (nut) 20,
The movement is converted into forward and backward movement of the slide cylinders 18 by 20, and the respective slide cylinders 18 and 18 simultaneously start a forward movement operation coaxially toward the left and right wall surfaces W and W directions of a corner portion C such as a room. When the rotation operation of the operating handle 11 is further continued, the slide cylinders 18 advance forward while pressing the coil springs 21 and 21 against their respective elastic forces. 16, 16 perform the forward operation.

Therefore, the fixing portion 22 for fixing the angle of the fixing portion at the end thereof moves forward and backward together with the outer boxes 16 and 16 and the fixing portions 30 and 30 connected to the fixing portions 22 and 22 are connected to the corner portion C. If you move forward in the left and right wall W, W direction,
First, when the wall portion W comes into contact with the wall surface W from the surface side (the lower side in the figure) of the fixed portion 30 having a small gap with the wall surface W and continues to advance in this state, the ball 26 in the fixed portion angle correcting portion 25
Are rolled in the recess 24 to rotate the fixing portion 30 counterclockwise, so that the entire fixing surface side of the fixing portion 30 is pressed against the wall surface W (see FIG. 6). If the forward operation is further continued, the fixing projections 32, 32 are sequentially inserted into the left and right wall surfaces W, W of the corner portion C, and the fixing portions 30, 30 are sequentially inserted.
Can be tightly fixed to the wall surface.

When the blind portion 34 is provided as shown in this embodiment, when the fixed portion is not used (when the fixed portion is housed), no pressing force is applied to the elastic members 33, 33, so that the blind portion 34 is fixed. The protrusion projection holes 35, 35
2 and 32, the fixing protrusion 3
No. 2 and 32 are not exposed, and are not only very good in appearance but also very useful in terms of safety.

At this time, the left and right fixing projections 32, 3
With 2 slightly stabbed on the corner walls W, W,
If the rotation operation of the operation handle is stopped, the attachment position can be confirmed again at this time. If the position change is desired, the operation handle 11 is rotated in the reverse direction to release the sticking state once, and the positioning is performed again. I can do it. Fixing projections 32, 32
Is slightly (shallow), and the damage to the wall surface is minute and extremely inconspicuous.

Accordingly, the fixing projections 32, 3 which are stabbed on the respective wall surfaces W, W (refer to a state of being stabbed and fixed).
2, the shelf 1 is firmly held at an arbitrary position of the corner portion C.

If the operating handle 11 is rotated in the direction opposite to the direction of rotation during the shelf mounting operation, the reverse rotation is transmitted simultaneously to the left and right forward and backward moving parts 15 and 15, and the left and right moving forward and backward. The portions 15, 15 start a retreating motion in the direction opposite to the forward motion, and the left and right fixing portions 30, 30 are simultaneously disengaged from the left and right wall surfaces W, W of the corner portion in the room, and the fixing state is released.

Further, the fixing projections 32, 32 fixed to the corner wall surfaces W, W are constantly pressed in the wall surface W, W direction by the coil springs (elastic members) 21, 21. , Corner wall surface W, W
Even if the corner wall surfaces W, W interval are slightly widened (shown by arrows in the figure) in a state where they are fixedly attached therebetween, their coil springs (elastic members) 21,
In the allowable range of 1, the coil springs (elastic members) 21 and 21 are extended, and the fixing portions 30, 30 are pushed forward (in the direction of the wall surface W, W) in accordance with the widening of the wall surface W, W interval. There is. Therefore, the entire fixing portion 30 protrudes from the contact edge 2a by the amount of the spread, and the fixing portions 30, 3
0, the state of maintaining adhesion to the wall surfaces W, W is ensured, and the shelf 1
Is prevented from falling (see FIG. 7).

For example, even if the corner wall surfaces W, W on which the shelves 1 are disposed due to factors such as an earthquake, are slightly wider than the original wall surface intervals, the fixing portions 30, 30 may be fixed to the wall surfaces W, W.
There is no inconvenience that the shelves 1 are dropped off from W.

The corner shelf structure of the present invention may be arranged in a plurality in the height direction of the corner portion C.
Also, shelves having different shapes or shelves of different sizes may be juxtaposed, and their arrangement and combination are arbitrary. In the above description, the mounting operation in the case where the corner angle of the wall surface W is wider than 90 degrees instead of 90 degrees has been described. However, if the corner surface of the wall surface W is 90 degrees, there is no inconvenience. And securely fix the fixing portions 30, 30 to the wall surfaces W, W
Needless to say, it can be fixed in close contact.

According to the present invention, the left and right forward and rearward moving parts can be easily moved forward simultaneously by operating a single handle integrally provided on the back surface of the shelf plate, and the fixing protrusions of the forward and rearward moving parts can be obtained. Can be stabbed on corner walls such as indoors,
A shelf plate with two non-parallel sides that is a shape suitable for the corner shape can be held at the corner part, and the removal work can be done simultaneously by rotating the operation handle in the opposite direction to the above attachment work, so that the left and right forward and backward parts are simultaneously At the time of installation work, which can be easily made to move backward,
If the rotation operation of the operation handle is stopped with the left and right fixing projections slightly stuck to the corner wall, the mounting position can be checked again at this time, and if the position change is desired, the operation handle Is rotated in the reverse direction to release the stab state once, and positioning can be performed again.
Because the sticking state of the fixing protrusion is slight, the damage to the wall surface is also small, and the operation and effect unique to the present invention are exhibited.
The mounting work is very easy and reliable, and even if the shelf board is once mounted at a predetermined position and positioned, the positioning work can be repeatedly performed easily.

Further, the present invention has a structure in which the left and right forward and rearward moving parts integrally provided on the back surface of the shelf board can be simultaneously moved forward and coaxially to be fixed to the left and right wall surfaces of a corner in a room or the like. Therefore, the effect that the forward and backward moving portions are fixed to the left and right wall surfaces of the room or the like without escaping the fixing force in the wall direction to the front is exerted, thereby holding the shelf board firmly and securely. It can support a considerable weight.

Further, since the left and right forward / rearward movement portions are fixed to the left and right wall surfaces of the corner such as a room only by rotating the single operation handle, the shelf plate is held in a predetermined position with one hand and the other is pressed. The function and effect that the fixing work can be performed easily and reliably by hand is exhibited, and a novel and useful corner shelf structure can be provided in which the shelf installation work in the corner portion is very easy and reliable, and the installation is completed in a short time.

Unlike the conventional one in which the left and right fixing members can be moved forward and backward on the rear surface of the shelf plate and are separated from each other, attachment and detachment work is extremely easy. Also, there is no risk of parts being lost.

A mechanism that can be fixed only by rotating a single operation handle is provided integrally with the back surface of the shelf plate, instead of a structure that is mounted via a bracket as in the conventional corner shelf structure. It is not only easy and easy to install the shelf, but also has good appearance and excellent appearance and aesthetics. Therefore, various inconveniences that have conventionally occurred when a shelf is mounted on a corner portion of a room or the like are sufficiently resolved.

In the prior art, when the corner on the wall surface to be mounted does not match the corner angle of the shelf board (for example, the corner on the wall surface to be mounted is 90 degrees with respect to the corner angle of the shelf board of 90 degrees). In this case, the wall surface to be attached and the shelf plate fixing portion are not parallel to each other, so that the adhesion between the two surfaces is reduced, and it is difficult to securely and firmly attach the shelf plate to the corner of the wall surface. As a result, in addition to the problem that the mounting state is unstable and things cannot be put on the shelf board at the bottom, the worst case (when the parallelism between the shelf fixing surface and the target wall surface is extremely low, etc.) There was a possibility that a situation where a shelf board could not be attached to a wall corner could be caused.

Therefore, according to the present invention, since the fixed portion is connected via a fixed portion angle correcting portion so as to be able to swing right and left at the front end position of the forward and backward moving portion, it is a novel and useful device. Even if there is a slight error in the corner of the target wall, the angle of the fixed portion can be fixed and firmly installed in accordance with the error by correcting the angle of the fixed portion, and a stable and strong installation can be provided.

That is, even if the corner on the wall surface to be mounted does not coincide with the corner angle of the shelf board (for example, the corner on the wall surface to be mounted is 90 degrees with respect to the corner angle of the shelf board of 90 degrees). If the mounting surface does not have parallelism between the wall surface to be mounted and the shelf plate fixing portion, the fixing portion swings right and left by the fixing portion angle correcting portion, and the angle of the fixing portion is set to the target wall surface. Therefore, the entire fixing surface side of the fixing portion can be closely fixed to the wall surface W. Therefore, the inconvenience of being unable to be attached at the construction site unlike the related art is eliminated.

Further, by adopting the structure of the present invention, the elastic member can be fixed even if the corner wall surface on which the corner shelf board is provided is slightly wider than the original wall space due to, for example, an earthquake. It is possible to expect a function and effect unique to the present invention such that the part is detached from the wall surface and the shelf board does not drop and the shelf board is reliably and safely.

That is, since the fixing projection fixed to the corner wall surface is always pressed toward the wall surface by the elastic member, the fixing protrusion is fixed between the corner wall surfaces and should be mounted. Even if the interval between the corner walls is slightly widened, the elastic member has an effect of pushing the fixing portion forward (toward the wall surface) in accordance with the expansion of the wall interval within the allowable range of the elastic member. Only the entire fixing portion protrudes from the contact side edge, and the state in which the fixing portion is fixed to the wall surface is secured, and the shelf board is prevented from dropping, which is safe.
