Description

  The present invention relates to a display shelf assembly structure in which a base end portion of a shelf receiving member that holds a display shelf board is detachably fixed to a square hole of a support column.

  A plurality of struts having a vertically long square hole provided in a vertical direction, a shelf receiving member that protrudes in the horizontal direction starting from a support piece inserted into the square hole and holds the lower surface of the display shelf, Various inventions have been proposed for an assembly structure realized by an engaging member (a stopper) that is movably mounted in a mounting groove of a shelf receiving member (Patent Documents 1 to 3).

JP 2010-187745 A Japanese Utility Model Publication No. 1-128627 Japanese Utility Model Publication No. 50-3784 Japanese Utility Model Sho 61-199248 U.S. Pat. No. 5,022,621 U.S. Pat. No. 4,406,374

  For example, the invention of Patent Document 1 adopts a configuration in which the lower end surface of the mounting groove is projected longer than the upper end surface, and a retaining protrusion is provided at the tip of the lower end surface (FIG. 7 of Patent Document 1). Therefore, there is a problem in operability that the stopper cannot be inserted straight and has to be inserted in an inclined posture from an obliquely upward direction. In this configuration, when the retaining protrusion is provided at the tip of the upper end surface of the mounting groove, the retaining tool can no longer be inserted.

  On the other hand, in the case of adopting a configuration in which a pair of retaining projections are provided on the upper end surface and the lower end surface of the mounting groove (FIG. 14 of Patent Document 1), the retaining tool can be inserted straight, and in this sense, it is easy to operate Are better.

  However, when adopting this configuration, it is necessary to provide a pair of upper and lower elastic pieces in the stopper, and to provide protrusions at the open ends of the elastic pieces, respectively, in order to be locked to the pair of retaining protrusions. There is a problem that the structure of the stopper is complicated. Moreover, the accuracy of the protruding height of the pair of retaining protrusions is required. If the projecting height is too high, the retaining member cannot be inserted, and conversely, if it is too low, the retaining portion may come off.

  Furthermore, in the configuration of Patent Document 1, since it is necessary to closely fit the base end portion of the coil spring 23 to the boss portion (spring receiving protrusion 28), the assembly work of the coil spring 23 is very complicated. In addition, if the base end part of the coil spring 23 is not closely fitted to the boss part, the coil spring easily falls off from the stopper until the stopper is mounted in the mounting groove.

  In addition, in any of Patent Documents 1 to 3, the structure of the stopper (engaging member) that is automatically positioned at the optimum position is suggested even if the dimensions of the square holes (mounting holes) of the columns are different. It has not been. In Patent Documents 4 to 6, a stepped or tapered member is provided in relation to the shelf receiving member. However, these members are not members that can be elastically moved. It is impossible to move to the optimal position.

  Hereinafter, examples will be described in more detail. FIG. 1: is a perspective view which shows the structural member about the assembly | attachment structure of the display shelf based on an Example.

  As shown in FIG. 1 (a), this assembly structure has a vertically long square hole HO provided with a plurality of square holes HO at the same pitch Pi, and a support piece inserted into the vertical rectangular hole HO. A shelf receiving member (shelf receiving bar) 2 protruding in a plate shape in the horizontal direction starting from the BS, a display shelf plate 3 whose lower surface is supported by a plurality of shelf receiving members 2, and a notch formed in the shelf receiving member 2 The engaging member 4 is movably mounted on the mounting portion FX.

  FIG. 1B shows a state in which the engaging member 4 is mounted on the mounting portion FX of the shelf receiving member 2 (see the arrow in FIG. 1A), and the engaging member 4 is surely dropped. It is possible to move in the horizontal direction in a state that is prevented. As will be described later, the engaging member 4 is not necessarily attached to the shelf receiving member 2 in a so-called fitted-in state, and is removed from the shelf receiving member 2 only by an artificial pulling operation without using a jig. It is also possible to adopt a configuration.

  As shown in FIG. 1A, a pair of support pieces BS, BS formed in an inverted J shape corresponding to the arrangement pitch Pi of the square holes HO is continuous in the vertical direction on the shelf receiving member 2. Is formed. As shown in the figure, the inverted J-shaped folded inner surface forms stop surfaces F1 and F2 that are flat in the horizontal direction. The support pieces BS, BS are formed with flat upper surfaces U1, U2 and flat lower surfaces L1, L2 extending in the horizontal direction.

  As shown in FIG. 1B, the separation distance between the flat upper surfaces U1 and U2, the separation distance between the flat lower surfaces L1 and L2, and the separation distance between the stop surfaces F1 and F2 are all set to the same dimension as the arrangement pitch Pi. ing. Further, the vertical height H of the support pieces BS and BS is set to be appropriately lower than the vertical height of the square hole HO, and the work of inserting the support pieces BS and BS into the square holes HO and HO is facilitated. Yes.

  As shown in the figure, vertical surfaces D1 and D2 are formed substantially orthogonal to the stop surfaces F1 and F2 of the support pieces BS and BS, respectively. The downward hanging surface D2 on the lower side is formed corresponding to the plate thickness of the column 1 and hangs down at a position almost in contact with the column 1 in the assembled state (see FIG. 3C).

  On the other hand, the upper drooping surface D1 hangs down at a position that does not contact the support column 1 even in the assembled state (see FIG. 3C), thereby facilitating the assembling work. The upper hanging surface D1 is continuous with the retaining protrusion PR located below, and the upper and lower end surfaces of the retaining protrusion PR are suspended at a position where they can substantially contact the support column 1 in the assembled state (see FIG. 3).

  Next, the mounting portion FX includes an accommodation groove GV that forms a substantially identical accommodation width (vertical height) continuously on the lower flat upper surface U2, and an inlet width that is narrower than the accommodation width at the open end of the accommodation groove GV. And a retaining protrusion PR that forms the structure. As described above, the upper and lower end surfaces of the retaining protrusion PR correspond to the position of the downwardly hanging surface D2.

  FIG. 2 is a drawing for explaining the engaging member 4. As shown in the figure, the engaging member 4 is roughly divided into a synthetic resin-made main body part BY and a coiled elastic spring SP inserted into the main body part BY. The main body part BY has a pair of gripping pieces 10 and 10 facing each other with a separation distance corresponding to the plate thickness of the shelf support member 2, and an insertion piece 11 provided between the gripping pieces 10 and 10. Configured.

  Note that the engaging member 4 of the embodiment has a maximum height H of the gripping piece 10 of about 8 mm, a maximum dimension L from the insertion piece 11 to the gripping piece 10 of about 20 mm, and the total weight is reduced to about 1 g. It is a small member made.

  The pair of gripping pieces 10 and 10 is used when the engaging member 4 is mounted in the receiving groove GV and when the shelf receiving member 2 is separated from the support column 1 after the shelf support member 2 is fixed to the support column 1. This is the part that the operator holds and moves in the direction of the arrow shown in the figure.

  The gripping piece 10 is composed of a plate-like portion 10a that forms a substantially vertical surface in use and a raised portion 10b that forms a raised shape in the mounting direction in consideration of its use. That is, in the present embodiment, the horizontal moving operation is facilitated by providing the raised portion 10b that gradually becomes thicker in the moving direction at the time of mounting (see FIG. 2D).

  In addition, the vertical height of the gripping piece 10 is set higher than the vertical height (storage width) of the receiving groove GV, and the horizontal length of the gripping piece 10 is more appropriately than the cutting depth (left-right width) of the receiving groove GV. It is formed long. Therefore, in a state where the engagement member 4 is mounted in the accommodation groove GV, the accommodation groove GV is covered with the gripping piece 10 regardless of the movement position of the engagement member 4 (see FIG. 1B). .

  Next, the insertion piece 11 will be described. A cylindrical opening hole (accommodating cylindrical hole) 12 for holding the elastic spring SP is formed on the proximal end side of the insertion piece 11 (see FIG. 2D). .

  Here, the opening hole 12 includes a large-diameter cylindrical hole 12a having an inner diameter slightly larger than the outer diameter of the elastic spring SP, a small-diameter cylindrical hole 12c that is substantially the same as the outer diameter of the elastic spring SP and forms a slightly smaller depth, and a taper. The connecting hole 12b is shaped into a shape (see FIG. 2 (f)). For example, by pushing the elastic spring SP into the bottom of the opening hole 12 (small-diameter cylindrical hole 12c) with the round bar-shaped jig inserted into the elastic spring SP, the base end of the elastic spring SP is , And fix to the bottom of the opening hole 12.

  For example, in the conventional configuration such as Patent Document 1, it is necessary to tightly fit the end of the spring to the protrusion provided on the engaging member, and the spring that easily contracts can be tightly fitted to the protrusion. Although not easy, in the configuration of this embodiment, it is sufficient to push the elastic spring SP strongly into the small-diameter cylindrical hole 12c of the opening hole 12, so that the mounting operation is very easy. In addition, in the case of the present embodiment, an appropriate gap is formed between the large-diameter cylindrical hole 12a and the elastic spring SP, so that a reliable expansion and contraction operation of the elastic spring SP is ensured.

  Further, the depth of the opening hole 12 is formed to a depth that can accommodate about 1/3 to 2/5 of the total length of the elastic spring SP in a natural state, and the elastic spring is equivalent to the depth of the opening hole 12. The entire length of the SP can be secured long. Therefore, in this embodiment, as the spring coefficient is small, the contraction stress accumulated in the pressurization state for a long time (see FIG. 3E) is small, and the durability can be improved. Further, since the entire length of the elastic spring SP is long, it is easy to set the contraction to an optimum dimension, and a desired repulsive force can be easily realized.

  Specifically, in the case of the embodiment, the depth of the opening hole 12 is about 1/3 to 2/5 of the entire length of the elastic spring SP in the natural state, and therefore, the conventional configuration (for example, Patent Document 1) is concerned. When compared with the spring used in the joint member, the total length can be doubled or more. Therefore, when springs with the same material, the same wire diameter, the same opening diameter, and the same pitch are configured, the spring coefficient is inversely proportional to the number of turns, and it is easy to set the contraction distance corresponding to the optimum repulsive force. The optimal contraction state can be realized.

  Next, the insertion piece 11 will be described. The bottom surface BT of the insertion piece 11 is positioned above the bottom surface of the gripping piece 10 to form a flat horizontal surface (FIGS. 2C and 2G). reference). The bottom surface BT of the insertion piece 11 is a portion that slides on the flat upper surface U2 of the receiving groove GV when the engaging member 4 is mounted or when the shelf receiving member 2 is separated from the support column 1, and the bottom surface BT of the insertion piece 11 Is formed on a flat surface, the horizontal movement with good operability is realized.

  Further, the insertion piece 11 is roughly divided into a tip portion 11a having the lowest height, a central portion 11b having one step higher, and a base end portion 11c having the highest height, based on the difference in height from the bottom surface BT. As shown in FIG.

  2 (a) to 2 (d), the plate thicknesses of the tip portion 11a and the central portion 11b are described identically, but by changing the plate thickness from the center portion 11b toward the tip portion 11a, It is preferable to make the tip tapered (see the plan view of FIG. 2G). If such a structure is taken, based on the urging | biasing force of the elastic spring SP, the approach operation in which the insertion piece 11 is automatically inserted in the square hole HO of the support | pillar 1 will be smoothed, and it will approach easily to an optimal position.

  The base end portion 11c is formed with a locking piece 13 that jumps in an arc shape toward the central portion 11b. The jumping height of the locking piece 13 is set corresponding to the storage width in the vertical direction of the receiving groove GV, and the protruding tip of the locking piece 13 with the engaging member 4 mounted in the receiving groove GV. Is formed so as to reach the upper surface of the accommodation groove GV.

  Further, the locking piece 13 is configured to exhibit appropriate elasticity, and when the engaging member 4 is mounted in the receiving groove GV against the elasticity of the elastic spring SP (in FIG. 2A). The smooth mounting operation is realized by being deformed by yielding by being pressed by the retaining protrusion PR. As described above, when the engagement member 4 is mounted, the bottom surface BT of the insertion piece 11 smoothly slides on the flat upper surface U2 of the accommodation groove GV, and the locking piece 13 yields and deforms in accordance with this sliding. Thus, a smooth mounting operation in the horizontal direction is realized.

  In order to realize such yield deformation, the amount of protrusion of the retaining protrusion PR and the accuracy of the jumping height of the locking piece 13 are not particularly problematic. Therefore, in this embodiment, the shelf receiving member 2, In particular, there is an advantage that the work accuracy of the retaining protrusion PR is not particularly required.

  The locking piece 13 that has passed through the retaining projection PR returns to its original jumping shape, and its protruding tip almost reaches the upper surface of the receiving groove GV. When the operator releases the gripping pieces 10 and 10 after such mounting operation, the engaging member 4 moves in the separating direction based on the elasticity of the elastic spring SP. Since the protruding tip comes into contact with the retaining projection PR, further movement is reliably prevented.

  Further, even when a strong external force is applied for some reason, the engaging tip 4 is reliably prevented from falling out of the receiving groove GV by reliably contacting the protruding tip of the locking piece 13 with the retaining protrusion PR. The Note that the work accuracy of the retaining protrusion PR and the locking piece 13 is not a problem in realizing this drop-off preventing operation.

  By the way, in the illustrated example, the locking piece 13 is formed to jump up in the shape of a reverse arc, but if it is formed in a linear shape that rises linearly and its protruding tip is made into an appropriate round shape, it will be pulled out slightly stronger Only by the operation, the protruding tip of the locking piece 13 gets over the retaining protrusion PR, so that the locking piece 13 can be pulled out. In addition, even if the fitting and killing structure is well known, a structure that can ensure a reliable holding state and can be manually removed when necessary is not well known.

  FIG. 3 is a drawing for explaining the operation procedure of the assembly structure of the first embodiment. First, the shelf support member 2 to which the engagement member 4 is mounted is positioned in a horizontal posture corresponding to the square hole HO of the support column 1 (FIG. 3A), and the support pieces BS and BS of the shelf support member 2 are Insert into square holes HO, HO. Then, as shown in FIG. 3B, in response to the support pieces BS and BS entering the square holes HO and HO, the non-opening portion of the column 1 comes into contact with the engagement member 4 and engages. The member 4 is pressed rightward in the drawing.

  Thereafter, the shelf receiving member 2 is further advanced, and the lower hanging surface D2 of the shelf receiving member 2 is brought into contact with the non-opening portion of the support column 1, and then the shelf receiving member 2 is lowered (see FIG. 3C). Then, the square hole HO is located in front of the engaging member 4 lowered together with the shelf receiving member 2. Therefore, thereafter, based on the elastic force of the elastic spring SP, the engaging member 4 moves leftward in the drawing, and the insertion piece 11 of the engaging member 4 enters the square hole HO.

  When the engaging member 4 enters the square hole HO to some extent, the protruding tip of the locking piece 13 is brought into contact with the retaining protrusion PR, thereby preventing further entry. As shown in the drawing, in this embodiment, the distal end portion 11a of the insertion piece 11 is configured to enter the square hole HO with a margin, but the central portion 11b has a size close to the upper inner surface of the square hole HO. Since it is configured, the assembling work is completed at the stationary position of FIG. In the present embodiment, since the locking piece 13 has a jumping shape, the engagement member 4 can be reliably prevented from coming off from the receiving groove GV. Moreover, since the center part 11b is set to a dimension close to the upper inner surface of the square hole HO in the approached state, rattling after assembly is reliably prevented.

  By the way, since the engaging piece 4 of the first embodiment has a stepped shape at the distal end portion 11a and the central portion 11b, the insertion piece 11 has different dimensions of the support piece BS and the square hole HO. Can be used. 3 (d) to 3 (e) illustrate this relationship, and the vertical height of the support piece BS is reduced from H to h in FIG. 3 (a). The case where the vertical dimension of the square hole HO is miniaturized corresponding to is shown.

  FIG. 3D shows a state in which the support pieces BS, BS of the shelf receiving member 2 are inserted into the square holes HO, HO, and each member is the same as in FIGS. 3A and 3B. To work. However, the distal end portion 11a of the insertion piece 11 is configured to have a size close to the upper inner surface of the miniaturized square hole HO, and the central portion 11b is configured to have a size that cannot enter the miniaturized square hole HO. Therefore, it stops in the state of FIG.

  That is, according to the engaging member 4 of the present embodiment, there is an advantage that it can be used regardless of the difference in the dimensions of the support piece BS and the square hole HO. Since the first embodiment has a two-step step shape, only the two-pattern assembly structure shown in FIGS. 3C and 3E can be realized. Alternatively, if a linear or curved taper shape is used instead of the step shape, a multi-pattern assembly structure can be realized.

  If this point is confirmed, even if it is the structure which takes a taper shape, if the support pieces BS and BS of the shelf support member 2 are inserted into the square holes HO and HO of the support column 1 and the shelf support member 2 is lowered, the elastic spring SP Since the insertion piece 11 protrudes to the optimum position by the biasing force, the upper surface of the insertion piece 11 holds the upper inner surface of the square hole HO at the optimum position. That is, the linear or arcuate taper shape absorbs the difference in the height direction of the square hole HO of the support column 1, and the support column 1 and the shelf support member 2 are integrated at the optimum position to prevent rattling. be able to.

  On the other hand, when the shelf receiving member 2 is separated from the support column 1, the gripping piece 10 is held, the engaging member 4 is retracted to the bottom side (right side in FIG. 3) of the receiving groove GV, and the holding state is maintained. Thus, after the shelf receiving member 22 is lifted to the position of FIG. 3B, the support piece BS of the shelf receiving member 2 is pulled out from the square hole HO of the column 1.

  By the way, in this pulling-out operation, it is very complicated to pull out the shelf receiving members 2 one by one, and it is often desired to finish the pulling-out operation at a stretch. For example, as shown in FIG. 4 (a), the left and right shelves are arranged from the square holes HO and HO of the support columns 1 and 1 while the display shelf 3 is placed on the pair of left and right shelf receiving members 2 and 2. There are cases where it is desired to pull out the receiving members 2 and 2 at once. Further, as shown in FIG. 4B, with the display shelf 3 placed on the shelf receiving members 2 and 2, the mounting positions in the square holes HO and HO are moved several steps up and down. Sometimes you want to.

  In FIG. 4A, a retaining protrusion 51 for preventing the display shelf 3 from slipping down is provided at the tip of the shelf receiving member 2, and two horizontal bars are provided on the lower surface of the display shelf 3. 52 is arranged. And the display shelf board 3 and the whole shelf receiving members 2 and 2 are integrated with the left and right shelf receiving members 2 and 2 sandwiching the horizontal bar 52 on the lower surface of the display shelf board 3. If it can move collectively, it is very convenient in the transfer operation | work to another display position, and the adjustment operation of display height. In addition, these points are not restricted to the shelf receiving members 2 and 2 integrated with the display shelf board 3, For example, as shown in FIG.4 (c), both ends of hanger pipe HG are made into a pair of shelf receiving members 2 , 2 is also the same.

  In view of this point, the shelf receiving member 2 of the second embodiment is provided with a temporary fixing portion LK that temporarily holds the engaging piece 13 of the engaging member 4 on the bottom side of the receiving groove GV. The temporary locking part LK is, for example, a locking projection LKa (FIG. 5A) that can lock the protruding tip of the locking piece 13, or a locking hole LKb that can receive the protruding tip (FIG. 5B). It is realized by.

  The temporary fixing part LK can also be realized by a tight part LKc in which the bottom side of the accommodation groove GV is narrowed (see FIG. 5C). In the configuration of FIG. 5C, the protruding height of the tight portion LKc is substantially the same as or slightly higher than the protruding height of the retaining projection PR corresponding to the elastic force of the locking piece 13. .

  In any case, in this embodiment, the locking piece 13 of the engaging member 4 has moderate elasticity and rises toward the retaining projection PR. Therefore, any of FIGS. 5 (a) to 5 (c) Even in this configuration, it is possible to maintain the temporarily fixed state in which the front end surface FT of the engaging member 4 is retracted from the upper and lower end surfaces (downward surface) of the retaining protrusion PR toward the bottom side of the housing groove GV.

  That is, in the configuration of FIGS. 5A and 5B, when the gripping piece 10 is held and the engagement member 4 is appropriately retracted in the depth direction (right direction) of the housing groove GV, the locking piece 13 moves over the temporary locking part LK. Thereafter, even if the gripping piece 10 is released, the protruding tip of the locking piece 13 is locked to the locking protrusion LKa, or the locking piece 13 protrudes. Since the tip end is immersed in the locking hole LKb, the engagement holding state of the engagement member 4 is maintained, and the tip end surface FT of the insertion piece 11 is stably stopped inside the accommodation groove GV.

  5C, when the holding piece 10 is held and the engaging member 4 is retracted to the limit position in the depth direction of the receiving groove GV, the elastic locking piece 13 becomes narrower. The holding state is maintained by pressing the inner wall of the tight part LKc.

  In any configuration, when the engaging member 4 is held by the temporary fixing portion LK, the distal end lower surface SF of the insertion piece 11 is configured to be located inside the upper and lower end surfaces of the retaining projection PR. Therefore, the shelf support member 2 can be freely moved up and down. Therefore, when the shelf receiving member 2 of the second embodiment shown in FIG. 5 is used, a drawing operation that is performed at a time as shown in FIGS. 4A to 4C can be performed.

  When the work contents are specifically confirmed, first, the holding piece 10 of the engaging member 4 is held and moved toward the bottom of the receiving groove GV, so that the temporary fixing portion LK is functioned. a) to the temporary holding state shown in FIG.

  In this manner, when the temporary fixing operation for temporarily holding the two engaging members 4 and 4 mounted on the shelf receiving members 2 and 2 is completed, the pair of left and right shelf receiving members 2 and 2 can be freely moved. Therefore, after that, the shelf receiving members 2 and 2 integrated with the display shelf 3 and the hanger pipe HG can be pulled out at once, and can be moved to another mounting position in the integrated state. .

  After the movement is completed, if the gripping piece 10 is held in a state where the shelf receiving members 2 and 2 are lowered (see FIG. 3C) and the engaging member 4 is guided toward the entrance of the housing groove GV. The protruding tip of the locking piece 13 that has passed over the temporary locking portion LK is now locked to the retaining protrusion PR, so that it is stabilized at the original stop position. Therefore, after that, the shelf receiving member 2 does not come out of the square hole HO of the column 1.

  As described above, according to the shelf receiving member 2 of the second embodiment, the shelf receiving members 2 and 2 integrated with the display shelf 3 can be moved in one operation. If such a configuration is not adopted, the shelf receiving member 2 cannot be pulled out from the square hole HO unless the display shelf 3 and the hanger pipe HG are separated from the shelf receiving members 2 and 2.

  Although the shelf receiving member 2 of the second embodiment has been described above, the shape of the support column 1 and the engaging member 4 can be changed. FIG. 6 shows a configuration in which heavier exhibits can be held by arranging two shelf receiving members 2 and 2 adjacent to one support column 1. In such a case, if the adjacent distance of the square hole HO is increased, there is a problem that the support column 1 is enlarged.

  Therefore, in this embodiment, the adjacent distance between the two square holes HO and HO is set to the minimum necessary size, and the upper and lower halves of the gripping piece 10 of the engaging member 4 are cut off. FIG. 6 (b) is a view showing the engaging member 4. In the pair of left and right gripping pieces 10R, 10L, the upper half raised portion 10b of one gripping piece 10R is cut off, and the horizontal portion 10a is substantially cut. While forming a continuous upper continuous surface, the lower raised portion 10b of the lower half of the other gripping piece 10L is cut away to form a lower continuous surface substantially continuous with the horizontal portion 10a.

  In other words, since the horizontal portion 10a extends over the entire horizontal direction of the gripping pieces 10R and 10L, one base end surface SR of the pair of base end surfaces SL and SR is L-shaped, The other base end surface SL has an inverted L shape obtained by rotating the L shape 180 degrees counterclockwise.

  Therefore, the total width W (= W1 + W2 + W3) of the horizontal width W1 of the insertion piece 11, the left-right width W2 of the horizontal portion 10a, and the maximum left-right width W3 of the raised portion 10b coincides with the left-right pitch W of the two square holes HO, HO. By doing so, it is possible to cope with the square holes HO and HO set to the minimum necessary dimensions (see FIG. 6D).

  According to this configuration, since a total of four shelf support members 2 can be disposed on the pair of left and right support columns 1 and 1, they can be stably held regardless of the total weight of the exhibit. (See FIG. 6C). In addition, since the adjacent distance between the two square holes HO and HO can be maintained at the minimum required dimension W, the support column 1 does not increase in size.

  Incidentally, in the first embodiment shown in FIGS. 1 and 2, the configuration in which the distal end side of the insertion piece 11 has a stepped shape or a tapered shape has been described, but the height direction of the square hole HO of the support column 1 is made common. In such a case, the insertion piece 11 may have a linear shape. FIG. 7 illustrates such a configuration. The insertion piece 11 forms a horizontal plane that extends straight on both the upper surface and the lower surface, and a locking piece 13 that rises linearly is formed in the middle of the upper surface. ing. In the illustrated example, the linear locking piece 13 is provided, but it is needless to say that a curved jumping shape similar to the previous embodiment may be used.

  In the first embodiment described above, the single retaining protrusion PR is provided. However, the present invention is not necessarily limited. For example, the retaining protrusion PR is vertically moved in accordance with the provision of the locking pieces 13 at two positions. It may be provided in two places. Regardless of whether or not there are a plurality of retaining projections PR, the locking piece 13 is not necessarily essential and may be omitted. FIG. 8 is a drawing showing such an embodiment. As shown in FIG. 8B, the shelf receiving member 2 has the retaining projections PR opposed to the upper and lower portions of the entrance portion of the housing groove GV. Is formed.

  Further, as shown in FIG. 8A, the engaging member 4 is not an integrally molded product, but the first member 4a and the second member 4b are manufactured separately, and then assembled to the shelf receiving member 2 , Integrated. As illustrated, the first member 4a is provided with an insertion piece 11 and a first gripping piece 100a, and the second member 4b is provided with a protruding pin 14 and a second gripping piece 100b. Further, the insertion piece 11 is formed by a distal end portion 11a and a central portion 11b similar to those of the first embodiment, and a base end portion 11c extending in the vertical direction corresponding to the retaining projection PR. An opening hole 12 that receives the elastic spring SP and a fitting hole 15 that receives the protruding pin 14 are formed in the base end portion 11c.

  At the time of the assembling work to the shelf receiving member 2, the first member 4 a and the second member 4 b are arranged so as to sandwich the receiving groove GV with the elastic spring SP arranged in the opening hole 12. Then, when the projecting pin 14 is press-fitted into the fitting hole 15, the engaging member 4 is integrated and the assembling work of the engaging member 4 to the shelf receiving member 2 is completed. In this embodiment, it is difficult to remove the engaging member 4 from the receiving groove GV, but it can be removed by releasing the press-fitted state using, for example, a thin plate-like removal plate.

  As mentioned above, although the structure which moves the engaging member 4 to a horizontal direction was demonstrated in the Example so far, it is not limited to this structure, The structure which moves to the rotation direction within a vertical surface can also be taken. 9 to 12 are drawings illustrating such an embodiment. In any case, protruding shafts 20 and 20 are formed to protrude from the engaging member 4, and the shelf receiving member 2 includes the protruding shafts 20 and 20. A round hole 21 that can accommodate 20 without difficulty is formed. Although not particularly limited, in the following embodiments, the retaining projection PR is not formed in the accommodation groove GV.

  First, the engaging member 4 in FIG. 9 is formed by integrally molding the arc plate-like gripping pieces 10 and 10 formed at an arc angle of about 90 ° and the insertion piece 11 provided between the pair of gripping pieces 10 and 10. Has been configured. And the elastic spring SP is hold | maintained at the insertion piece 11, and it will be in a completion state.

  As shown in the figure, a pair of protruding shafts 20, 20 are formed to protrude on the inner surfaces of the gripping pieces 10, 10. Further, a small arc surface 31 and a large arc surface 32 having different curvature radii are formed concentrically on the insertion piece 11. In addition, the first surface 33 and the second surface 34 are formed in a step shape continuously to the open distal end side of the small arc surface 31 and the large arc surface 32, while the base ends of the small arc surface 31 and the large arc surface 32 are formed. On the side, an opening hole 12 of the elastic spring SP is formed.

  In this embodiment, in the mounted state shown in FIG. 9 (f), the large arc surface 32 comes into surface contact with the lower inner surface of the accommodation groove GV, and the small arc surface 31 lines with the end of the upper inner surface of the accommodation groove GV. A stable stationary state is achieved by contact. In order to further stabilize this state, a retaining protrusion PR may be formed at the line contact position of the accommodation groove GV. In any case, in the stable stationary state of FIG. 9F, in this embodiment, the first surface 33 located above the large arc surface 32 and the second surface 34 located below are two A horizontal plane is formed. However, it is not particularly limited, and the second surface 34 located on the lower side may be an inclined surface extending upward in the horizontal direction in the mounted state shown in FIG.

  In this embodiment, when the engaging member 4 is mounted on the shelf receiving member 2, the gripping pieces 10 and 10 are positioned so as to sandwich the shelf receiving member 2, and the gripping piece 10 is slid as it is. The protruding shafts 20 and 20 are slid into the round holes 21 of the shelf support member 2. As described above, the round hole 21 is formed to be appropriately larger than the protruding shaft 20, and thereafter, the engaging member 4 is moved counterclockwise around the protruding shaft 20 inserted into the round hole 21. Can be rotated in the direction.

  Moreover, when the insertion piece 11 is pressed by the support | pillar 1, the engaging member 4 rotates counterclockwise corresponding to this pressing force. That is, when the support pieces BS and BS of the shelf receiving member 2 are inserted into the square holes HO and HO in the mounted state shown in FIG. 9 (f), the insert piece 11 is pressed against the support column 1 to be engaged. The member 4 rotates counterclockwise, and the state shown in FIG. After that, when the shelf receiving member 2 is lowered, the square hole HO is positioned in front of the engaging member 4 lowered together with the shelf receiving member 2, so that the engaging member is based on the elastic force of the elastic spring SP. 4 is bullet-rotated clockwise.

  The clockwise rotation is stopped when the second surface 34 holds the upper inner surface of the square hole HO or when the first surface 33 holds the upper inner surface of the square hole HO. Therefore, also in this embodiment, two patterns can be assembled in the same state as shown in FIGS. 3C and 3E. In any assembled state, the shelf receiving member 2 can be separated from the support column 1 by rotating the engaging member 4 counterclockwise. In the embodiment of FIG. 9, the first surface 33 and the second surface 34 are provided. However, when the assembly pattern is single, this can be omitted. FIG. 10 illustrates an embodiment without a step shape.

  Incidentally, although the coiled elastic spring SP is used in the embodiments so far, a plate-like elastic spring (plate spring) as shown in FIGS. 11 to 12 may be used instead. FIGS. 11 to 12 are drawings for explaining such a third embodiment. In correspondence with the use of the leaf spring SP, the shapes of the insertion piece 11 and the gripping piece 10 are the second embodiment of FIG. Unlike this, the rotation direction of the engagement member 4 is opposite to that in FIG.

  The leaf spring SP is divided into a base end portion 40 formed in a corrugated plate shape, an orthogonal portion 41 substantially orthogonal to the base end portion 40, and a curved portion 42 extending in an arc from the orthogonal portion 41. The bending portion 42 abuts on the inner surface of the accommodation groove GV and deforms into a small arc shape, thereby realizing a resilient rotation in which the engagement member 4 rotates in the clockwise direction (see FIG. 11G).

  The insertion piece 11 is roughly divided into a tip end portion 11a having the lowest height, a central portion 11b that is one step higher, and a base end portion 11c that forms the top surface having the highest height, and forms a step shape as a whole. ing. And the base end part 40 of the leaf | plate spring SP is fixedly accommodated in the opening hole 12 formed in the base end part 11c. As illustrated, the distal end portion 11a of the insertion piece 11 has a flat bottom surface BT, and realizes a stable and stable stationary state in the mounted state shown in FIG.

  Also in the third embodiment, the distal end portion 11a of the insertion piece 11 holds the upper inner surface of the square hole HO, or the center portion 11b is assembled in two patterns in which the upper portion of the square hole HO holds the upper inner surface. Is possible. If an arcuate taper shape TP is adopted instead of the step shape formed by the tip portion 11a and the central portion 11b, a multi-pattern assembly structure can be realized. FIG. 12 illustrates such an embodiment.

  As mentioned above, although the Example of this invention was described in detail, the concrete description content does not specifically limit this invention, and an appropriate change is possible.
