Description

Shelf receiving member

[0001] The present invention relates to a shelf receiving member for receiving a shelf board for placing various items such as books, tableware, clothes, ornaments, etc.

[0002] Conventionally, there is known a shelf receiving member that receives a shelf board via a support pin (peg) provided on a fixed wall, which includes a cup body and a movable body disposed within the cup body. By moving the movable body, it has a two-member configuration that is non-removably connected to the support pin. However, in such a shelf receiving member with a two-member configuration, the structure becomes complicated and it is difficult to reduce costs.

[0003] On the other hand, as a one-member configuration shelf receiving member, for example, there is known a fixture for attaching a shelf board via a support pin provided on a fixed wall, and a support pin can be press-fitted between a pair of opposing side wall portions that are elastically deformable in a direction intersecting the axial direction and the vertical direction of the support pin (see Patent Document 1). In this fixture, the pair of opposing side wall portions described above are configured to hold the circumferential surface of the press-fitted support pin.

[0004] Japanese Patent Application Laid-Open No. 2016-191443

[0005] By the way, in the fixture described in Patent Document 1, since a pair of opposing side wall portions that are elastically deformable in a direction intersecting the axial direction and the vertical direction of the support pin hold the circumferential surface of the support pin, when an external force is applied to the fixture to remove it from the support pin, the pair of opposing side wall portions may elastically deform so as to separate from each other, and there is a risk that the fixture will come off the support pin, making it difficult to improve the connection strength between the fixture and the support pin.

[0006] An object of the present invention is to provide a one-member configuration shelf receiving member capable of improving the connection strength.

[0007] [1] The shelf support member of the present invention is a shelf support member that supports a shelf board via a support pin provided protruding from a fixed wall, and comprises a main body having a housing space for housing the protruding portion of the support pin, and an engaging piece disposed in the housing space and engaging with the support pin, wherein the main body has a first opening that opens the housing space in the axial direction of the support pin and a second opening continuous with the first opening and opening the housing space downward, and the engaging piece is elastically deformable in the axial direction and engages with the protruding portion of the support pin from below.

[0008] [2] In the shelf support member of the present invention, the engaging piece may engage with the protruding portion from below at a position on a virtual vertical line passing through the axis of the support pin.

[0009] [3] In the shelf support member of the present invention, the engaging piece may be configured to be continuous with the main body at its upper end and to be elastically deformable more significantly in the axial direction at its lower end than at its upper end.

[0010] [4] In the shelf support member of the present invention, the protruding portion of the support pin has a head, the housing space has a space portion in which the head is housed, and the engaging piece is positioned at an intermediate position in the axial direction within the space portion.

[0011] [5] In the shelf support member of the present invention, the engaging piece may have an engaging claw portion provided on its lower end and engaging with the protruding portion of the support pin from below, and an operating portion configured below the engaging claw portion. [6] In the shelf support member of the present invention, vertical ribs may be formed on the circumferential surface of the main body portion.

[0012] The present invention aims to provide a shelf support member with a single-component structure that can improve engagement strength.

[0014] [Configuration of this Embodiment] Hereinafter, embodiments of the present invention will be described based on the drawings. In Figures 1 to 6, the shelf support member 10 according to this embodiment supports the shelf board 2 of the shelf body 1 shown in Figure 1. The shelf body 1 comprises a pair of side plates 3 as fixed walls and the aforementioned shelf board 2 arranged between the pair of side plates 3. Support pins 5 (see Figure 2, etc.) are provided on the side plates 3, protruding toward the shelf board 2, and the shelf support member 10 is fitted into a recess 6 appropriately formed on the end portion of the lower surface of the shelf board 2 and connected to the support pins 5. In Figure 1, the shelf support member 10 is shown arranged in one of the multiple recesses 6, but in reality, the shelf support member 10 is arranged in each of the multiple recesses 6. In the following description, for the sake of explanation, the left-right direction of the shelf body 1 will be the X-axis direction, the depth direction of the shelf body 1 will be the Y-axis direction, and the up-down direction of the shelf body 1 will be the Z-axis direction. The X, Y, and Z axis directions are orthogonal to each other. In this embodiment, the X and Y axis directions are horizontal, and the Z axis direction is vertical. Furthermore, for the sake of clarity, the directions of the shelf support members 10 shown in Figure 1 will be described using the X, Y, and Z axis directions mentioned above. In reality, the directions of each shelf support member 10 are appropriately changed depending on the installation orientation of each shelf support member 10.

[0015] [Support pin] In this embodiment, the support pin 5 (dowel) is made of metal and is provided on the side plate 3 so that its axis O is aligned with the X-axis direction. Therefore, the X-axis direction is also the axis direction of the support pin 5.

[0016] The support pin 5 has a base shaft portion 51 that is screwed into the side plate 3, an enlarged diameter portion 52 that is continuous with the base shaft portion 51 and has a larger diameter than the base shaft portion 51, a small diameter portion 53 that is continuous with the enlarged diameter portion 52 and has a smaller diameter than the enlarged diameter portion 52, and a head portion 54 that is continuous with the small diameter portion 53 and has a larger diameter than the small diameter portion 53.

[0017] The base portion 51, the enlarged diameter portion 52, and the small diameter portion 53 each have circumferential surfaces 511, 521, and 531, respectively. The head portion 54 has an inclined circumferential surface 541 that slopes toward the small diameter portion 53.

[0018] The circumferential surface 511 of the base shaft portion 51 has a threaded portion (not shown) that is screwed into a hole (not shown) provided in the side plate 3. However, it is not limited to this configuration, and the shaft may be inserted into the hole without having such a threaded portion.

[0019] The surface 522 of the enlarged diameter portion 52 on the side of the base shaft portion 51 abuts against the inner surface 3A of the side plate 3 when the base shaft portion 51 is screwed into the side plate 3.

[0020] The small-diameter portion 53 is positioned between the enlarged-diameter portion 52 and the head portion 54, thereby forming the neck portion of the support pin 5.

[0021] The head portion 54 is positioned in the housing space 12, which will be described later, and engages with the engaging claw portion 32, which will be described later.

[0022] The enlarged diameter portion 52, the smaller diameter portion 53, and the head portion 54 constitute a protruding portion 50 that protrudes in the X-axis direction from the inner surface 3A of the side plate 3.

[0023] [Shelf support member] In this embodiment, the shelf support member 10 is made of synthetic resin and has a main body portion 11 having a housing space 12 for housing the protruding portion 50 of the support pin 5, and an engaging piece portion 31 which is arranged in the housing space 12 and engages with the support pin 5.

[0024] The main body portion 11 integrally comprises a substantially cylindrical cylindrical portion 13 that forms the outer peripheral surface 131, a housing portion 14 that is positioned inside the cylindrical portion 13 and forms a housing space 12, and a lower plate portion 15 that is continuous with the lower ends of the cylindrical portion 13 and the housing portion 14 and extends outward from the cylindrical portion 13. A weight-reducing space 16 is formed between the cylindrical portion 13 and the housing portion 14.

[0025] The cylindrical portion 13 has a first opening 21 formed on the side plate 3 side that is open in the X-axis direction. The first opening 21 is formed in a slit shape, extending upward from the lower plate portion 15. The portion of the outer circumferential surface 131 of the cylindrical portion 13 that forms the first opening 21 is made into a flat surface so that it can be positioned along the inner surface 3A of the side plate 3. In addition, the cylindrical portion 13 is provided with a plurality of transverse ribs 132 that protrude outward along the circumferential direction of its outer circumferential surface 131. The transverse ribs 132 press against the inner circumferential surface of the recess 6 when the shelf support member 10 is fitted into the recess 6 of the shelf board 2, thereby maintaining the fitted state of the shelf support member 10.

[0026] The housing section 14 has an inner surface 140 that forms the housing space 12, as shown in Figure 3, for example. The inner surface 140 has a bottom surface 141 along the Y-axis direction and a pair of side surfaces 142 that are continuous with both edges of the bottom surface 141 along the Z-axis direction and along the X-axis direction. The pair of side surfaces 142 are configured symmetrically with respect to the axis O of the support pin 5 when it is placed in the housing space 12, so the components of the pair of side surfaces 142 are appropriately given the same reference numerals.

[0027] The side portion 142 has a first housing surface portion 143 on the side of the first opening 21, a second housing surface portion 144 on the side of the bottom portion 141, and a third housing surface portion 145 positioned between the first housing surface portion 143 and the second housing surface portion 144. The lower end of the portion constituting the third housing surface portion 145 is positioned above the operating section 33, which will be described later (see Figure 4).

[0028] In the housing section 14, an upper wall portion 146 is formed in the portion from the upper part between the pair of first housing surfaces 143 to the intermediate position in the X-axis direction between the pair of third housing surfaces 145, and this upper wall portion 146 is designed to hold the support pin 5 in place from above. The portion from the intermediate position in the X-axis direction between the pair of third housing surfaces 145 to the upper part between the pair of second housing surfaces 144 is an upward-extending portion. The upper part of the engaging piece portion 31 is continuous with the upper part of the second housing surface 144. Furthermore, a space is formed between the engaging piece portion 31 and the bottom surface portion 141, extending in the Z-axis direction, and by forming this space, a region is provided in which the engaging piece portion 31 can bend in the X-axis direction.

[0029] The distance in the Y-axis direction between the first housing surface 143 of the pair of side portions 142 is approximately equal to or slightly larger than the diameter of the enlarged portion 52 of the support pin 5. The distance in the Y-axis direction between the third housing surface 145 of the pair of side portions 142 is smaller than the diameter of the head 54 of the support pin 5, and slightly larger than the small diameter portion 53 of the support pin 4. The distance in the Y-axis direction between the second housing surface 144 of the pair of side portions 142 is approximately equal to or slightly larger than the diameter of the head 54 of the support pin 5. For this reason, the third housing surface 145 protrudes in the Y-axis direction more than the first housing surface 143 and the second housing surface 144. The second housing surface 144 and the third housing surface 145 are slightly inclined so that they taper from the bottom to the top. The head 54 of the support pin 5 is positioned in the space between the pair of second housing surface 144.

[0030] The lower plate portion 15 has a circular outer edge portion 151 and a flat edge portion 152 that is continuous with the outer edge portion 151 and is in a straight line along the Y-axis direction. The flat edge portion 152 is arranged along the inner surface 3A of the side plate 3.

[0031] The lower plate portion 15 has a second opening 22 that opens the storage space 12 downwards. The second opening 22 is continuous with the first opening 21 and extends from the first opening 21 in a slit shape in the X-axis direction.

[0032] The engaging piece 31 is positioned at an intermediate position in the X-axis direction between the pair of second housing surfaces 144, bridging the upper parts of the pair of second housing surfaces 144 in the Y-axis direction. The engaging piece 31 extends in the Z-axis direction and is elastically deformable in the X-axis direction. An engaging claw portion 32 is formed at the lower end of the engaging piece 31, projecting toward the first opening 21 in the X-axis direction. Furthermore, an operating portion 33, which is operated in the X-axis direction, is formed in the portion of the engaging piece 31 below the engaging claw portion 32. The operating portion 33 is positioned further away from the first opening 21 in the X-axis direction compared to the engaging claw portion 33. The lower end of the operating portion 33 is formed flush with the lower surface of the lower plate portion 15. In addition, since the operating portion 33 is disposed in the housing space 12 opened by the first opening 21 and the second opening 22, the operating portion 33 can be easily operated by inserting a tool or fingers into the housing space 12 (see Figures 4 and 6, etc.).

[0033] [Connection Procedure] The procedure for connecting the shelf support member 10 to the support pin 5 will be described below. First, position the second opening 22 of the shelf support member 10 above the protruding portion 50 of the support pin 5.

[0034] Next, the shelf support member 10 is lowered, and the protruding portion 50 is inserted into the storage space 12 through the second opening 22. At this time, the enlarged diameter portion 52 of the support pin 5 is positioned between the pair of first storage surfaces 143, the small diameter portion 53 is positioned between the pair of third storage surfaces 145, and the head portion 54 is positioned between the pair of second storage surfaces 144. The head portion 54 is pulled towards the bottom surface portion 141 by the inclined circumferential surface 541 sliding against the pair of third storage surfaces 145. The head portion 54 also faces the engaging piece portion 31 in the X-axis direction.

[0035] Next, when the shelf support member 10 is lowered further, the head 54 abuts against the engaging claw portion 32 from below, and as the head 54 pushes the engaging claw portion 32, the engaging piece portion 31 is elastically deformed in the X-axis direction toward the bottom surface portion 141. At this time, since there is space on the bottom surface portion 141 side of the engaging piece portion 31, the risk of the elastically deformed engaging piece portion 31 interfering with the main body portion 11 can be reduced. Subsequently, when the head 54 moves upward toward the engaging claw portion 32 in the Z-axis direction, the elastically deformed engaging piece portion 31 returns to its original state, and the engaging claw portion 32 engages with the head 54 from below in a snap-fit ​​manner. At this time, the engaging claw portion 32 engages with the head 54 at a position on a virtual vertical line V passing through the axis O of the support pin 5. As the engaging claw portion 32 engages with the head portion 54 in this manner, compared to, for example, an elastically deformable engaging portion (not shown) that engages with the head portion 54 at a position on the Y-axis side with respect to a virtual vertical line V, the engaging piece portion 31 can be positioned using the space in the X-axis direction, which is also the axis direction of the support pin 5, thereby making the shelf support member 10 more compact. In the engagement state described above, the enlarged diameter portion 52 of the support pin 5 contacts the pair of first housing surfaces 143 and the upper wall portion 146 of the housing portion 14, thereby suppressing the swing of the shelf support member 10 relative to the support pin 5 in the Y-axis and Z-axis directions, the small diameter portion 53 contacts the pair of third housing surfaces 145, thereby suppressing the swing of the shelf support member 10 relative to the support pin 5 in the Y-axis direction, and the head portion 54 is pulled towards the bottom surface portion 141, thereby suppressing the swing of the shelf support member 10 relative to the support pin 5 in the X-axis direction. In this way, the shelf support member 10 is connected to the protruding portion 50 of the support pin 5.

[0036] For example, in the connected state where the shelf support member 10 is connected to the protruding portion 50 of the support pin 5, even if the shelf support member 10 is pulled upward to try to release the connection with the support pin 5, the engaging piece 31 is configured to be elastically deformable in the X-axis direction rather than the Y-axis direction. Therefore, compared to, for example, an elastically deformable engaging portion (not shown) that contacts the support pin 5 on the Y-axis side, elastic deformation is less likely to occur in the engaging piece 31, and thus the aforementioned release of the connection is less likely to occur. Furthermore, since the engaging claw portion 32 is engaged at least at a position on a virtual vertical line V passing through the axis O of the support pin 5, that is, directly below the head portion 54, the engaged state can be firmly maintained even if the shelf support member 10 is pulled upward to try to release the connection with the support pin 5.

[0037] When assembling the shelf unit 1, the shelf support members 10 are connected to the support pins 5 using the aforementioned connection procedure, which allows the shelf boards 2 to be easily attached to the pair of side boards 3 and prevents the shelf boards 2 from accidentally coming off.

[0038] To release the connection between the shelf support member 10 and the support pin 5, the operating part 33 is moved in the X-axis direction toward the bottom surface 141 using fingers or a tool such as a screwdriver to release the engagement between the engaging claw 32 and the head 54, and the shelf support member 10 is pulled upward from the support pin 5. In this way, the connection between the shelf support member 10 and the support pin 5 is released.

[0039] [Modification] In the above embodiment, transverse ribs 132 are formed on the circumferential surface of the main body, that is, the outer circumferential surface 131 of the cylindrical portion 13. However, the invention is not limited to this, and for example, as shown in Figure 7, instead of transverse ribs 132, multiple vertical ribs 133 extending in the Z-axis direction may be formed on the outer circumferential surface 131. In this case, it is possible to easily pull up and remove the shelf board 2 while the shelf support member 10 is connected to the support pin 5.

[0040] In the above embodiment, transverse ribs 132 are formed on the outer circumferential surface 131 of the cylindrical portion 13, but in addition, a plurality of the aforementioned longitudinal ribs 133 may be formed on the outer circumferential surface 131.

[0041] In the above embodiment, the engaging claw portion 32 engages with the head 54 from below at least at a position on a virtual vertical line V passing through the axis O of the support pin 5. However, it is not limited to this, and for example, the engaging claw portion 32 may be made to have a shape complementary to the inclined circumferential surface 541 of the head 54, and configured to engage with the head 54 from below around the position on the virtual vertical line V.

[0042] In the above embodiment, the engaging piece 31 has an operating portion 33 located below the engaging claw portion 32, but the configuration of the operating portion 33 is not limited to this, and the configuration of the operating portion 33 may be omitted. Even in this case, the engagement between the engaging claw portion 32 and the head 54 of the support pin 5 can be released by pushing the engaging claw portion 32 in the X-axis direction with a tool or the like.

[0043] In the above embodiment, the head portion 54 is pulled towards the bottom portion 141 by bringing its inclined circumferential surface 541 into contact with the third housing surface portion 145. However, the third housing surface portion 145 may also have an inclined guide surface formed thereon to pull the head portion 54 towards the bottom portion 141. If such a guide surface is formed, the head portion 54 may have a non-inclined circumferential surface (not shown) instead of the inclined circumferential surface 541.

[0044] [Summary of Embodiment] (1) The shelf receiving member 10 of the present embodiment is a shelf receiving member 10 that receives the shelf board 2 via the support pin 5 provided to protrude from the side plate 3 which is a fixed wall. The shelf receiving member 10 has a main body portion 11 having an accommodation space 12 for accommodating the protruding portion 50 of the support pin 5, and an engagement piece portion 31 disposed in the accommodation space 12 and engaging with the support pin 5. The main body portion 11 has a first opening 21 that opens the accommodation space 12 in the X-axis direction which is the axial direction of the support pin 5, and a second opening 22 that is continuous with the first opening 21 and opens the accommodation space 12 downward in the Z-axis direction. The engagement piece portion 31 is elastically deformable in the X-axis direction which is the axial direction, and engages with the protruding portion 50 of the support pin 5 from below in the Z-axis direction. According to the shelf receiving member 10 of the present embodiment, by passing the protruding portion 5 of the support pin 5 through the first opening 21 and the second opening 22 and causing elastic deformation in the X-axis direction which is the axial direction in the engagement piece portion 31, the protruding portion 50 can be disposed in the accommodation space 12. Further, for example, when the peripheral surface of the support pin 5 is a circumferential surface, even if an external force is applied to the shelf receiving member 10 to remove it from the support pin 5, it is difficult for elastic deformation in the X-axis direction which is the axial direction to occur in the engagement piece portion 31. Therefore, the connection strength between the shelf receiving member 10 and the support pin 5 can be improved.

[0045] (2) In the shelf receiving member 10 of the present embodiment, the engagement piece portion 31 engages with the protruding portion 50 from below at a position on the virtual vertical line V passing through the axis O of the support pin 5. According to such a configuration, even if the peripheral surface of the support pin 5 is a circumferential surface, the engagement state between the engagement piece portion 31 and the protruding portion 50 of the support pin 5 can be maintained more preferably, and the connection strength between the shelf receiving member and the support pin 5 can be further improved.

[0046] (3) In the shelf receiving member 10 of the present embodiment, the engagement piece portion 31 is continuous with the main body portion 11 on the upper end side in the Z-axis direction and is configured to be elastically deformable more greatly in the X-axis direction which is the axial direction on the lower end side in the Z-axis direction than the upper end side. According to such a configuration, when passing the protruding portion 50 of the support pin 5 upward from the second opening 22, the engagement piece portion 31 can be elastically deformed preferably in the X-axis direction which is the axial direction.

[0047] (4) In the shelf receiving member 10 of the present embodiment, the protruding portion 50 of the support pin 5 has the head portion 54 of the support pin 5, the accommodation space 12 has a space portion in which the head portion 54 is accommodated, and the engaging piece portion 31 is disposed at an intermediate position in the X-axis direction, which is the axial direction, in the space portion. According to such a configuration, the engaging piece portion 31 can be disposed opposite to the head portion 54 of the support pin 5 in the X-axis direction, which is the axial direction of the support pin 5, and even if the engaging piece portion 31 is elastically deformed in the X-axis direction, which is the axial direction, the risk of interference with the main body portion 11 can be reduced.

[0048] (5) In the shelf receiving member 10 of the present embodiment, the engaging piece portion 31 has an engaging claw portion 32 provided on the lower end side in the Z-axis direction thereof and engaging with the protruding portion 50 of the support pin 5 from below, and an operation portion 33 configured below the engaging claw portion 32. According to such a configuration, by engaging the engaging claw portion 32 with the protruding portion 50, the shelf receiving member 10 and the support pin 5 can be connected. On the other hand, by operating the operation portion 33 to elastically deform the engaging piece portion 31 in the X-axis direction, which is the axial direction, the engagement between the engaging claw portion 32 and the protruding portion 50 can be released, and the shelf receiving member 10 can be easily removed from the support pin 5. The operation portion 33 may be operated by a finger or the like, or may be operated by inserting a tool such as a driver.

[0049] (6) In a modified example of the shelf receiving member 10 of the present embodiment, vertical ribs 133 are formed on the outer peripheral surface 131 (circumferential surface) of the main body portion 11. According to such a configuration, the shelf board 2 disposed in the recess 6 by the shelf receiving member 10 can be easily removed from the shelf receiving member 10.
