In this shelf board holder, as the purport of the invention, a vertical distance from the center in the vertical direction of the engaging section to the lower face is selected to be nearly the same length as the vertical distance from the center in the vertical direction of the lock hole, for the engaging section to engage with, to the upper face of the shelf board supported on the lower part of the lock hole.

Description

  The present invention relates to a shelf holder, and more particularly to a shelf holder that prevents a shelf in a shelf such as a bookshelf or a display shelf from being removed by an external force.

  A shelf such as a bookshelf or a display shelf is usually configured by suspending a shelf plate in one or more stages between a pair of left and right side plates. However, shelves where the shelves are firmly connected to the left and right side plates are rare, and it is necessary to adjust the vertical spacing between the shelves and make the shelves removable. In general, it is engaged and locked with a locking tool attached at an appropriate position and suspended between side plates.

  However, in such a conventional shelf, for example, when a force that pushes upward on the shelf board due to an earthquake or the like acts, the shelf board jumps upward and a display such as a book placed on the shelf falls, In the worst case, the shelf board may come off the locking tool and fall.

  Conventionally, as a device for preventing an object such as a book from falling from a shelf when an unexpected external force is applied, such as during an earthquake, for example, as shown in Patent Documents 1 and 2, the shelf board is tilted forward. It has been proposed that a fall prevention guard is attached to the front surface of the shelf as seen in Patent Documents 3 and 4. However, these proposals are intended to prevent books and other objects placed on the shelf board from falling off the shelf. It is not something to prevent.

  On the other hand, in Patent Document 5, in the shelf having a structure in which the shelf board is locked to the dowel attached to the side board, the outer diameter of the dowel is set in order to prevent the shelf board from falling off the dowel during an earthquake or the like. A shelf has been proposed in which an inverted L-shaped shelf removal prevention tool having a combined round hole is inserted into a dowel, and a shelf board is fixed on an adhesive member adhered to the upper surface of the shelf removal prevention tool. ing. However, in this proposal, since the shelf board is only fixed to the upper surface portion of the shelf detachment prevention tool with an adhesive member, the shelf board may be detached from the shelf removal prevention tool when a strong external force is applied. There is. In addition, since the shelf is fixed to the upper surface of the inverted L-shaped shelf detachment prevention tool inserted into the dowel, the position of the suspended shelf is different from the position originally restricted by the dowel. There is.

  The present invention has been made to solve the above-described drawbacks of the prior art, and even when a strong external force is applied to push the shelf upward from the bottom in a state where the shelf is suspended at the original suspension position, It is an object of the present invention to provide a shelf presser that can effectively prevent the plate from jumping upward or falling off the locking tool.

  As a result of intensive research efforts to solve the above-mentioned problems, the present inventor originally used a plurality of locking holes provided in the side plate or the column in order to make the height of the shelf plate adjustable, A shelf presser is attached to the lock hole that is positioned above the shelf plate that is supported and suspended by the supporter that is attached to the locking hole, and that is not attached to the supporter. Even if a strong upward external force is applied in a state where the shelf is supported at the original suspension position by bringing the lower surface into contact with or close to the shelf supported and suspended downward, It has been found that it can effectively prevent jumping out and falling.

  That is, the present invention is a shelf plate pressing tool used in a shelf including a shelf plate supported by a supporting tool attached to a locking hole provided in a side plate or a support column, The main body has a fitting portion that fits into a locking hole that exists in a side plate or a column, and the main body is attached to the locking hole by fitting the fitting portion into the locking hole. A back surface having a portion that comes into contact with the periphery of the locking hole, a surface facing back to back at a distance from the back surface, and a lower surface formed between a lower side of the back surface and a lower side of the surface A vertical distance from the vertical center of the fitting portion to the lower surface of the shelf plate supported below the engagement hole from the vertical center of the locking hole into which the fitting portion is fitted. Provide a shelf holder that is selected to have a length approximately equal to the vertical distance to the top surface. It is intended to solve the above problems by the.

  Usually, in a shelf such as a bookshelf, in order to adjust the height of a shelf suspended between side plates or between columns, shelves are provided on inner surfaces facing each other of a pair of left and right side plates or two pairs of left and right columns. Locking holes for locking the support that supports the plate are provided at equal intervals in the vertical direction. However, the locking holes used for supporting and suspending the shelf board are a part of them, and other locking holes exist without being used. The shelf presser of the present invention is attached to a lock hole that is not used, so that even if a force that pushes upward is applied to the shelf in the event of an earthquake or the like, the shelf jumps upward or locks It is possible to prevent falling off the tool. That is, in the shelf holder according to the present invention, the vertical distance from the center in the vertical direction of the fitting portion that fits into the locking hole to the lower surface of the main body portion is the vertical distance of the locking hole into which the fitting portion is fitted. Since the length is set to be approximately equal to the vertical distance from the center of the direction to the upper surface of the shelf supported and suspended below the engagement hole, it is used above the shelf after the shelf is suspended. When the shelf presser of the present invention is attached to the non-engagement locking hole, the lower surface of the main body of the shelf presser is in contact with or close to the upper surface of the shelf, and even when an upward external force is applied Is prevented from popping up or falling off the locking tool. In addition, although it is preferable that the locking hole to which the shelf presser of the present invention is attached is already provided in the side plate or the column, it is newly provided to attach the shelf presser of the present invention. It may be a locking hole.

  In a preferred aspect of the shelf holder according to the present invention, the main body has an upper surface formed between the upper side of the back surface and the upper side of the surface, and from the center in the vertical direction of the fitting unit. The vertical distance to the upper surface is substantially equal to the vertical distance from the vertical center of the locking hole into which the fitting portion is fitted to the upper surface of the shelf plate supported and suspended below the engagement hole. Has been chosen. In such a case, the shelf holder according to the present invention can be used in the same manner even if the shelf plate is turned upside down.

  Furthermore, in the other preferable one aspect | mode of the shelf board pressing tool of this invention, the perpendicular direction distance from the up-down direction center of the said fitting part to the said lower surface is the upper and lower sides of the locking hole which the said fitting part fits. The vertical center of the fitting portion is selected to have a length substantially equal to the vertical distance from the center of the direction to the upper surface of the shelf having the first thickness supported and suspended below the engagement hole. The vertical distance from the top surface to the top surface is from the vertical center of the locking hole into which the fitting portion is fitted to the top surface of the shelf plate having the second thickness that is supported and suspended below the locking hole. The length is selected to be approximately equal to the vertical distance. When the shelf presser of the present invention has such a configuration, the shelf presser of the present invention is turned upside down and attached to the locking hole of the side plate to cope with two types of shelf plates having different thicknesses. It can be very convenient.

  The shape of the main body part in the shelf presser of the present invention is not particularly limited as long as it can prevent the shelf board from jumping upward or falling on the lower or upper surface of the main body part. However, in a preferred embodiment of the shelf holder according to the present invention, the horizontal cross-sectional shape of the main body portion is an arc shape with a central angle of 180 degrees or less with the back surface side of the main body portion as a string, and the back surface side of the main body portion is a string. It is a bow shape with a central angle of 180 degrees or less, a square shape, or a U-shape with the back side of the main body portion as the opening side. When the main body has the horizontal cross-sectional shape as described above, when the shelf presser of the present invention is attached to the locking hole, the main body of the shelf presser has a wide range in the vertical direction. In this case, the attachment state is stable and preferable because the contact with and the contact with the peripheral portion of the locking hole is achieved.

  In particular, the horizontal cross-sectional shape of the main body portion is an arc shape with a central angle of 180 degrees or less with the back surface side of the main body portion as a chord, or an arc shape with a central angle of 180 degrees or less with the back surface side of the main body portion as a string. In this case, the surface shape of the main body portion draws a smooth curved surface with respect to the front-rear direction of the shelf board, so that not only books and other articles can be smoothly stored and taken out, but also books, etc. It is more preferable because the end of the article is less likely to be damaged by colliding with the corner of the shelf holder.

  Furthermore, when the horizontal cross-sectional shape of the main body is an arc shape with a central angle of 180 degrees or less with the back side of the main body as a string, or a U-shape with the back side of the body part as the opening side Since the length of the tongue pieces, which will be described later, constituting the fitting portion can be increased, the elasticity of these tongue pieces is increased, and the advantage that the attachment and removal can be easily performed is obtained. A gap is formed between the periphery of the blind hole and the back of the main body of the shelf holder, so it is possible to easily remove the shelf holder of the present invention by inserting a fingertip or the tip of a screwdriver into the gap. There is also an advantage that it can be done.

  Incidentally, in the shelf presser of the present invention, “up and down” means the vertical direction when the shelf presser of the present invention is attached to the side plate or the locking hole of the column. Therefore, the horizontal cross-sectional shape of the main body portion refers to a horizontal cross-sectional shape when the fitting portion is fitted in the locking hole and the shelf board pressing tool of the present invention is attached to the side plate.

  Furthermore, in another preferable aspect of the shelf presser according to the present invention, the fitting portion includes an upper tongue piece and a lower tongue piece having elasticity, and the upper tongue piece and the lower tongue piece include Each has a mountain-shaped convex portion protruding upward and downward. Such a fitting portion is suitable when the locking hole is a locking hole having a space that extends at least in the vertical direction from the opening. Such a locking hole has, for example, a U-shaped cross section in which a plurality of locking holes are formed in a groove provided in a side plate as disclosed in Japanese Patent No. 4746831 by the same applicant. It can be formed by attaching a metal fitting. Alternatively, it can be formed by punching out a hollow side plate or a support column and providing an opening to be a locking hole.

  In the case where the fitting portion in the shelf holder according to the present invention has elastic upper and lower tongue pieces, and these upper and lower tongue pieces have mountain-shaped convex portions protruding upward and downward, respectively, By fitting the fitting part into the locking hole so that the convex part is located inside the locking hole, the convex part spreads in the direction away from each other in the space inside the locking hole and functions as a retaining stopper. The shelf board pressing tool of the invention can be stably attached to the locking hole. In particular, at the time of fitting, the angle of the chevron is such that the slope on the base side of the upper and lower tongues of the convex part of the chevron is in contact with the edge inside the retaining hole of the member forming the retaining hole. When the position of the convex portion is selected, due to the elastic force of the upper and lower tongue pieces, a force directed to the inner side of the locking hole always acts on the shelf pressing member, and the locking of the shelf pressing member of the present invention is performed. Mounting in the hole is more stable.

  The shelf holder according to the present invention is effective when applied to a shelf of a bookcase mainly used in a library or the like, but is supported and suspended between a pair of opposed left and right side plates or between two opposed pairs of left and right columns. Of course, there are no particular restrictions on the contents and installation locations of the shelves having the shelves that can be applied to shelves such as display shelves, arrangement shelves, and storage shelves.

  According to the shelf presser of the present invention, the original support of the shelf that is supported and suspended between the opposing side plates or between the columns by a simple operation of simply attaching the shelf presser of the present invention to the locking hole. Even if a strong external force that pushes upward from the bottom is applied without changing the height, the shelf board can be effectively prevented from jumping upward or falling off the support. Benefits are gained. The shelf presser according to the present invention only needs to be fitted into a locking hole formed in the side plate or the column, can be easily attached, and can easily cope with changing the position of the shelf. . Further, in the shelf holder according to the present invention, when the vertical distance from the center position in the vertical direction of the fitting portion to the upper surface or the lower surface is made different, the thickness is increased by fitting the locking holes in the upside down direction. There is an advantage that it is possible to deal with different shelf boards.

  Hereinafter, the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the illustrated one.

  FIG. 1 is a front view showing an example of a shelf holder according to the present invention, FIG. 2 is a rear view thereof, FIG. 3 is a right side view thereof, and FIG. 4 is a plan view thereof. 1 to 4, reference numeral 1 denotes a shelf presser according to the present invention, and the shelf presser 1 has a main body 2 and a fitting part 3 coupled to the main body 2. 4 is the front surface of the main body 2, and 5 is the back surface of the main body 2, and the front surface 4 and the back surface 5 face each other with a distance between each other. Reference numeral 6 denotes a lower surface formed between the lower side of the front surface 4 and the lower side of the rear surface 5, and reference numeral 7 denotes an upper surface formed between the upper side of the front surface 4 and the upper side of the rear surface 5. 5a and 5b are portions where the back surface 5 comes into contact with the peripheral portion of the locking hole when the shelf plate pressing tool 1 is attached by fitting the fitting portion 3 into the locking hole of the side plate or the column. In the shelf presser 1 of the present invention, the vertical direction refers to the direction connecting the upper surface 7 and the lower surface 6 of the main body 2.

  FIG. 5 is a cross-sectional view taken along line X-X ′ in FIG. 1, that is, a horizontal cross-sectional view. As shown in FIG. 5, the horizontal cross-sectional shape of the main body 2 in the shelf holder 1 of this example is an arc shape in which the back surface 5 side of the main body 2 is a string and the front surface 4 side is an arc. In FIG. 5, the central angle of the arc indicated by α is preferably 180 degrees or less, more preferably 90 degrees or more and 150 degrees or less, and most preferably 100 degrees or more and 140 degrees or less. When the central angle α of the arc exceeds 180 degrees, the length of the arc becomes too long compared with the length of the string, and the shelf holder 1 is attached to the side plate of the shelf or the locking hole of the support column. If an external force in the horizontal direction toward the near side or the depth side is applied, it is not preferable because the shelf holder 1 is easily detached from the locking hole. On the other hand, when the center angle α of the arc is less than 90 degrees, the length of the front surface 4 of the main body 2 projecting forward becomes too short, and the shelf plate holder 1 is not moved downward even when fitted into the locking hole. This is not preferable because there is a possibility that the upper surface of the shelf plate that is supported and suspended is not sufficiently in contact. In addition, when the horizontal cross-sectional shape of the main body 2 is an arc shape with the back surface 5 side of the main body portion 2 as a string and the front surface 4 side as an arc, the peripheral portion of the locking hole and the back surface 5 of the main body portion 2 are used. Therefore, when removing the shelf holder 1, a fingertip or the tip of a driver can be inserted into the gap, which is very convenient.

  FIG. 6 is a Y-Y ′ cross-sectional view of FIG. 1, that is, a vertical cross-sectional view. As shown in FIG. 6, the fitting portion 3 is coupled to the back surface 5 of the main body portion 2. The main body 2 and the fitting portion 3 are preferably formed integrally with a synthetic resin having appropriate elasticity such as polypropylene and polyethylene, but the main body 2 and the fitting portion 3 are formed separately. Thereafter, the two may be bonded by an appropriate means such as adhesion or fusion. Polypropylene and polyethylene are examples of suitable synthetic resins that can be used, and other synthetic resins may be used as long as they have appropriate elasticity. Moreover, you may comprise the main-body part 2 and the fitting part 3 by a different material.

  In FIG. 6, L is a horizontal center line passing through the center of the fitting part 3 in the vertical direction, M is the vertical distance from the center of the fitting part 3 in the vertical direction to the lower surface 6, and N is the fitting part 3. The vertical distance from the center in the vertical direction to the upper surface 7 is shown. In this example, the vertical distance M and the vertical distance N are different, and are respectively supported below the engagement hole from the center in the vertical direction of the engagement hole into which the fitting portion 3 is fitted, as will be described later. A vertical distance to the upper surface of the shelf having the first thickness, and a second thickness supported below the locking hole from the vertical center of the locking hole into which the fitting portion 3 is fitted. The length is set equal to or approximately equal to the vertical distance to the upper surface of the shelf board. The vertical distance M and the vertical distance N are respectively the vertical distance to the top surface of the shelf board having the first thickness and the vertical distance to the top surface of the shelf board having the second thickness. If the shelf holder 1 is attached to the locking hole when the vertical distance is set to be equal to or slightly longer than the vertical distance, the lower surface 6 of the main body 2 or Since the upper surface 7 is in contact with the upper surface of the shelf plate supported and suspended below, the play of the shelf plate is eliminated, and the advantage that the shelf plate can be supported and suspended more stably is obtained.

  7, 8, and 9 are an enlarged rear view, an enlarged plan view, and a Z-Z ′ enlarged vertical sectional view in FIG. 7, respectively, showing only the fitting portion 3. 7-9, 8a is an upper tongue piece, 8b is a lower tongue piece, 9 is a frame body on either side, 10 is a flexible part formed comparatively thinly. Since the upper tongue piece 8a and the lower tongue piece 8b are connected to the left and right frame bodies 9 via the flexible portion 10, when the force is applied upward or downward, the upper tongue piece 8a moves downward or upward, and the force is lost. And it has elasticity to return to its original position again.

  11 is a convex portion having a mountain-like vertical cross section, and the convex portion 11 is composed of a back surface 5 side, that is, a slope 11a on the base side of the upper and lower tongue pieces 8a and 8b, a top portion 11b, and a slope 11c on the tip side. The convex portion 11 is provided on the tip end side of each of the upper tongue piece 8a and the lower tongue piece 8b. As shown in FIG. 9, the slope 11c on the tip end side is formed more gently than the slope 11a on the root side, and the fitting part 3 is smoothly in the direction of fitting into the locking hole and in the direction of removing. Is hard to come off.

  The flexible portion 10 may be omitted. For example, as shown in the enlarged rear view of FIG. 10 and the enlarged plan view of FIG. 11, the upper tongue piece 8a and the lower tongue piece 8b are made independent from the frame body 9, and cantilevered. It may be coupled to the back surface 5 in a beam manner and bend in the vertical direction by its own elasticity. Incidentally, if the shelf holder 1 is simply attached to the locking hole, it is conceivable that the tongue pieces 8a and 8b are provided on the left and right instead of the upper and lower sides. The tongue pieces 8a and 8b are preferably provided in the vertical direction from the viewpoint of preventing upward protrusion. Moreover, the structure of the fitting part 3 is not restricted to what was mentioned above, If it can be fitted to the locking hole currently formed in the side plate or the support | pillar, and the shelf board pressing tool 1 of this invention can be attached, In principle, any structure is acceptable.

  FIG. 12 is a perspective view showing an example of a shelf 100 to which the shelf holder 1 of the present invention is applied. In FIG. 12, 101 is a pair of left and right side plates, 102 is a bottom plate, 103 is a top plate, 104 is a metal fitting for a locking hole, and the metal fitting 104 for a locking hole has a plurality of same shapes and the same size at equal intervals in the vertical direction. The locking hole 105 is provided.

  FIG. 13 is an assembly view of the side plate 101. As shown in FIG. 13, two grooves 106 are formed in the longitudinal direction on the inner surface of the side plate 101, and the locking hole fitting 104 is fitted into the groove 106 and fixed with the mounting screw 107. A row of two locking holes 105 is formed in the side plate 101 in the vertical direction. The locking hole fitting 104 has a U-shaped horizontal cross section, and is attached to the groove 106 with the U-shaped opening side facing the groove 106, so that the locking hole metal fitting 104 is disposed inside the plurality of locking holes 105. In other words, the space that originally was the groove 106 is formed as a space that is wider in the vertical direction and the horizontal direction than the opening of the locking hole 105. Reference numeral 108 denotes a screw hole of the mounting screw 107.

  FIG. 14 is a partial enlarged cross-sectional view taken along the line W-W ′ in which the side plate 101 is cut along a vertical plane perpendicular to the inner side surface of the side plate 101 at a position including the locking hole fitting 104. In FIG. 14, V is a space extending inside the locking hole 105, and as is apparent from the drawing, the space V extends in the vertical direction and the horizontal direction of the locking hole 105. 109 is a support, 110 is a shelf board, and the shelf board 110 has a thickness D1.

  In this example, the support 109 is a metal fitting having an N-shaped cross section disclosed in Japanese Patent No. 4746831 filed by the same applicant, and one end thereof is inserted into the locking hole 105 and locked. Is attached to the locking hole 105. The other end of the support 109 is engaged with an engagement hole 111 provided at a side end of the shelf board 110. As described above, the shelf plate 110 is supported and suspended from the side plate 101 by the locking hole 105 and the support 109 attached to the locking hole 105.

C is a horizontal center line passing through the center in the vertical direction of the locking hole 105 positioned above the locking hole 105 on which the shelf board 110 is supported, and S ₁ is the center of the shelf board 110 from the center line C. The vertical distance to the top surface. In the shelf presser 1 of the present invention, the vertical distance M from the center line L indicating the center in the vertical direction of the fitting portion 3 to the lower surface 6 of the main body portion 2 is the factor to which the shelf presser 1 is to be attached. from the center line C vertical of Tomeana 105, supported on its lower or equal to the vertical distance S ₁ to the upper surface of the shelf plate 110 is suspended, set to be slightly longer than the vertical distance S ₁ Has been.

  FIG. 15 is a diagram illustrating a state in which the shelf board pressing tool 1 is attached to the locking hole 105 positioned immediately above the locking hole 105 in which the shelf board 110 is supported and suspended in the orientation illustrated in FIG. 14. It is. As shown in FIG. 15, when the fitting portion 3 is fitted into the locking hole 105 and the shelf board presser 1 is attached to the locking hole 105 positioned above the shelf board 110, the main body of the shelf board presser 1. The lower surface 6 of the part 2 is in contact with the upper surface of the shelf board 110 and presses the shelf board 110 downward. Thus, even if an external force that pushes upward on the shelf board 110 due to an earthquake or the like is applied, the shelf board 110 is restricted from moving upward, and if it does not jump upward, it falls off the support 109 and falls. There is nothing.

  Note that FIG. 15 shows only the shelf presser 1 attached to the locking hole 105 located on the front side of the left side plate 101 of the shelf 100, but it is formed on the depth side of the shelf of the shelf 110. Of course, the shelf board presser 1 can also be attached to the locking hole 105 located at the same height or the locking hole 105 located at the same height formed in the opposite right side plate. According to the shelf retainer 1 of the present invention, the shelf retainer 1 is attached to the four retaining holes 105 at least four positions on the left and right sides, and at least two diagonal lines per shelf. It is possible to prevent the plate 110 from jumping upward and falling from the support 109.

  FIG. 16 is a partially enlarged cross-sectional view showing only the fitting portion 3 and its peripheral portion in a state of being fitted in the locking hole 105. As shown in the figure, the fitting portion 3 is inserted and fitted into the locking hole 105, and the shelf board presser 1 makes a part of the back surface 5 of the main body portion 2 abut against the peripheral portion of the locking hole 105. In the state of being attached to the locking hole 105 in the state, the slope 11 a on the base side of the upper and lower tongue pieces 8 a, 8 b of the mountain-shaped convex portion 11 is related to the locking hole fitting 104 that forms the locking hole 105. It is in contact with the inner side of the blind hole 105, that is, the edge on the space V side. In the state of being fitted in the locking hole 105, the upper tongue piece 8a is applied with a force to return upward due to its elasticity, and the lower tongue piece 8b is applied with a force to return downward due to its elasticity. Therefore, a force indicated by an arrow in the figure, which attempts to draw itself into the inside of the locking hole 105, acts on the fitting portion 3 in which the slope 11a is in contact with the inner edge of the locking hole 105, The state in which the shelf holder 1 is attached to the locking hole 105 becomes more stable.

FIG. 17 is a partially enlarged cross-sectional view showing the side plate 101 cut along a vertical plane perpendicular to the inner surface of the side plate 101 at a position including the locking hole fitting 104, as in FIG. 14. It differs from the case shown in FIG. 14 in that the thickness is not D1 but D2. In FIG. 17, C is a horizontal center line passing through the center in the vertical direction of the locking hole 105 positioned on one of the locking holes 105 on which the shelf board 110 is supported, and S ₂ is from the center line C. This is the vertical distance to the top surface of the shelf board 110. Since the thickness of the shelf plate 110 is in D2, unlike the vertical distance S ₂ is naturally vertical distance S _1, the vertical direction from the vertical center of the fitting portion 3 of the shelf plate retainer 1 to the lower surface 6 It is also different from the distance M.

Even in such a case, the vertical distance N from the center line L indicating the center in the vertical direction of the fitting portion 3 in the shelf holder 1 to the upper surface 7 of the main body 2 is defined as the vertical distance S _2. If equal, by setting to be slightly longer than the vertical distance S _2, the shelf plate presser device 1 of the present invention can also support shelves 110 having a thickness of D2.

That is, FIG. 18 shows that the shelf board presser 1 is turned upside down in the direction shown in FIG. 17, and the locking hole 105 positioned immediately above the locking hole 105 supported and suspended by the shelf board 110. It is a figure which shows the attached state. Or vertical distance N is equal to the vertical distance S _2, since it is set to be slightly longer than the vertical distance S _2, as shown in FIG. 18, by the shelf plate retainer 1 upside down shelf When attached to the locking hole 105 located above the plate 110, the upper surface 7 of the main body 2 of the shelf presser 1 abuts on the upper surface of the shelf plate 110 to press the shelf 110 downward and upward. Is effectively prevented from falling out and falling from the support 109.

  As described above, in the shelf holder 1 of the present invention, the vertical distance M and the vertical distance N from the center in the vertical direction of the fitting portion 3 to the lower surface 6 and the upper surface 7 are made different from each other and the use is scheduled. By supporting the shelves with different thicknesses, even when the shelves 110 are changed to shelves with different thicknesses, it is possible to easily cope with them by simply turning them upside down. . In the shelf holder 1 of the present invention, the vertical distance M and the vertical distance N may be the same, and if they are the same, there is no need to consider the vertical direction when attaching. Benefits are gained.

  19 is a plan view showing another example of the shelf holder 1 of the present invention, and FIG. 20 is a horizontal sectional view thereof. In the shelf holder 1 of this example, the horizontal cross-sectional shape of the main body 2 is a bow shape with the back surface 5 side as a string. As described above, when the horizontal cross-sectional shape of the main body 2 is an arcuate shape, the back surface 5 can be obtained when the shelf holder 1 is attached to the locking hole 105 as compared with the case where the horizontal cross-sectional shape is an arc shape. And the contact area with the peripheral part of the latching hole 105 becomes large, and the advantage that the attachment state of the shelf holder 1 is stabilized is acquired. Even when the horizontal cross-sectional shape of the main body 2 is an arch shape, the central angle α of the arch shape is preferably 180 degrees or less for the same reason as described above for the case of the arc shape. It is more preferably 150 degrees or less and most preferably 100 degrees or more and 140 degrees or less.

  FIG. 21 is a plan view showing still another example of the shelf holder 1 of the present invention. In this example, the horizontal cross-sectional shape of the main body 2 is a quadrangle. Moreover, in this example, the flexible part 10 is not provided. When the horizontal cross-sectional shape of the main body 2 is a quadrangle, when the shelf holder 1 is attached to the locking hole 105, the contact area between the back surface 5 of the main body 2 and the peripheral portion of the locking hole 105 is small. It becomes large and the advantage that the attachment state of the shelf holder 1 is stabilized is acquired.

  FIG. 22 is a plan view showing still another example of the shelf holder 1 of the present invention. In this example, the horizontal cross-sectional shape of the main body 2 is a U-shape with the back surface 5 side as the opening side. . When the horizontal cross-sectional shape of the main body 2 is U-shaped, the length of the upper and lower tongue pieces 8a and 8b can be increased, so that the elasticity of the upper and lower tongue pieces 8a and 8b is increased and attached. The advantage that it can be easily removed is obtained. Moreover, the horizontal cross-sectional shape of the main-body part 2 is between the back surface of the main-body part 2 of the shelf holder 1, and the peripheral part of a locking hole similarly to the case where it is circular arc shape which makes the back surface side of the main-body part a string. Since the gap is formed, there is also an advantage that the shelf holder 1 can be easily removed by inserting a fingertip or the tip of a driver into the gap.

  FIG. 23 is a front view showing still another example of the shelf holder 1 of the present invention. As shown in the drawing, the shelf holder 1 of the present example has the lower surface 6 of the main body 2 inclined at an angle β with respect to the horizontal. In this way, by tilting the lower surface 6 of the main body 2, the shelf presser 1 of the present invention can be applied to a shelf that is supported and suspended in an inclined manner. Needless to say, the inclination angle β of the lower surface 6 coincides with the inclination angle of the shelf plate supported and suspended.

  The above description has been given of the case where the shelf presser 1 of the present invention is attached to the locking hole 105 that is widened at least in the vertical direction on the inside, but the shelf presser of the present invention is, for example, a dowel As a matter of course, it may be used by being attached to a cylindrical locking hole that does not have a spread on the inside. In this case, the shape and structure of the fitting portion 3 are fitted into the cylindrical locking hole. What can be combined.

  As described above, according to the shelf presser of the present invention, it is possible to hold the shelves in various shelves at predetermined positions with a simple operation using a simple member. Even when an external force that pushes up is applied, it is possible to significantly reduce the risk that the shelf board jumps upward and the stored items fall, or that the shelf board itself falls off the support and falls. The present invention greatly contributes to the improvement of the safety of various shelves including book shelves installed in libraries, various shops, offices, etc., and its industrial applicability is great.
