Description

  The present invention relates to a rack for luggage storage, in which racks are stacked up and down to load the luggage, and when the rack itself is stored in an unused state, the rack can be stacked vertically (nested) and stored in the rack. The present invention relates to a connection rack for a connection rack that is used by connecting the connection racks to each other when the connection racks are arranged in the left-right and lateral directions when storing the luggage.

  Conventionally, a type of pallet used for cargo handling is loaded with goods and transported by forklift trucks or hand lifts, stacked up and down to form racks when stored, and nested when not in use. A connecting rack (nesting rack) is known.

  FIG. 11 is a perspective view in which a nesting rack that also serves as a generally known transport container is drawn from the front. The transport container R has a front frame 110, a rear frame 120, and a side frame 130. The bottom frame 100 is assembled in a rectangular shape in plan view, and the outer peripheral sides of both side edges 130 and 130 of the bottom frame 100. A pair of front struts 121, 121 are erected at the front end of the bottom frame body, and a pair of back struts 141, 141 are erected on the outer peripheral side of the rear edge 120 of the bottom frame 100 to form a luggage storage space, At the same time, the lower ends of each of the front columns 121, 121 and the back columns 141, 141 are respectively projected below the bottom frame 100, and the bottom frame 100 is separated from the floor by a predetermined height to be separated from the floor surface. A gap for inserting a lift truck fork is provided between the two.

  And from the side surface opposite to the upper end part of each front support | pillar 121 of each support | pillar 121, 121, 141, 141 standing around the bottom frame 100 as mentioned above, the upper end part of each back support | pillar 141 is provided. A pair of upper rails 50, 50 having an upper surface formed in an inverted V-shaped fitting surface parallel to the depth direction toward the side surfaces that are separated from each other, and further aligned with the upper rails 50, 50, Below the bottom frame 10, a pair of bottom rails 60, 60 having a lower surface formed in an inverted V-shaped fitting surface (bottom surface concave portion) are provided.

  Reference numeral 131 is a reinforcing beam constructed on the upper end surfaces of the rear support columns 141 and 141 in order to make the transport container R have a rigid structure, and reference numeral 80 reinforces the joint portion of the front support column 121 with the bottom frame 100. It is a gusset. In order to construct the upper rail 50, the stay 70 is attached to the opposite side surfaces of the upper end portion of the front column 121, and the reinforcing beam 131 is extended to the opposite side surfaces of the back column 141. Further, on the bottom frame 100, vertical beams 140, 140 and horizontal beams 150, 150 are installed to reinforce the frame and to support a load to be loaded.

  In such a transport container R, a load is mounted directly on the bottom frame 100 or via a top plate or the like depending on the size of the load and is transported to a desired place by a lift truck. Since each column 121, 121, 141, 141 is provided on the outer peripheral side, cargo collapse is unlikely to occur, and when storing luggage in a warehouse or the like, a plurality of transport containers R, R are attached to the upper rails 50, 50. And the bottom rails 60, 60 can be stably stacked in a plurality of stages, the storage space such as a warehouse can be used effectively, and it can also be used as a storage rack, and on the luggage Since they are not stacked directly, they can be stored without damaging the luggage. Further, when the transport container R is not used, if the transport container R is stacked in a nested manner, the transport container R itself can be stored in a small occupied space.

  However, the generally known transport container R is fixed in the height direction, that is, the length of each of the columns 121, 121, 141, 141, so that the size of the luggage stored in the transport container R is in the height direction. Even if it is much smaller (lower) than each column 121, 121, 141, 141, the transport container R is stacked using the transport container R, and the luggage is stored in the warehouse. Since a meaningless empty space is formed in R, there is a need for a transport container that can efficiently use the height direction in the warehouse and operate the storage capacity in the warehouse more efficiently, and a connected rack. .

FIG. 4 is a front view (FIG. 4 (a)), a right side view (FIG. 4 (b)), and a top view (FIG. 4 (c)) for explaining the connecting rack used in the present invention. Is a connecting rack made of iron material. In this embodiment (Claim 1), the left and right side beam members 2 are placed on the bottom 1 and the rear part 3 of the left and right side beam members 2 are connected to each other. A bottom rack frame member 5 comprising a rear side beam member 4;
A front shelf frame member 6 having a width between the left and right side beam members 2 at an upper portion 8 and a left and right shelf frame side beam member 7 connected to the front shelf frame member at an inner position between the left and right side beam members 2; An upper rack member 10 composed of a desired shelf frame member 9 is a connecting rack 13 provided with left and right tubular front struts 11 and rear struts 12 extending vertically,
The left and right side beam members 2 are configured to shorten the width (W) of the front shelf frame member at the front portion, and the front column 11 extends from the left and right ends of the front shelf frame member 6 to the left and right side beam members. 2 are vertically connected to each other through a support member 14 mounted on
The rear column 12 is configured by vertically connecting the rear side beam member 4 placed on the rear part of the left and right side beam members 2 and the rear end of the left and right shelf side beam members 7 vertically.
Further, the tubular front column 11 and the rear column 12 are respectively connected to the front and rear column inner pipes 15, the front shelf frame member 6, the support member 14, and the left and right shelf frame side beam members 7, respectively. The connecting rack 13 is formed by fitting and connecting to a connecting system joint member 16 protruding from the rear side beam member 4.

  In short, the connecting rack has a U-shape formed by the left and right side beam members 2 and the rear side beam members 4 constituting the bottom portion 1, and the left and right side beam members 2 are formed at the front portion with the width (W ) Is shortened, the left and right side beam members 2 and the front column 11 of each connection rack 13 can be stacked without being obstructed when stacked in a stack (see FIG. 5).

  As shown in the plan view of FIG. 1 and the front view of FIG. 2, the present invention is a connection shelf 21 for a connection rack, which includes a front shelf frame member 6 a having a desired length, and the front shelf frame member. Left and right shelf frame side beam members 7a connected directly to the left and right ends of 6a, rear connection members 9b connected directly to the rear ends of the left and right shelf frame side beam members 7a, and the front shelf The frame member 6a, the left and right shelf frame side beam members 7a, and the rear connection member 9b are configured by an upper rack member 10a including a plurality of desired shelf frame members 9a.

  Furthermore, a hook member 22 that is hooked on the left and right ends of the upper rack member 10a from above the left and right shelf frame side beam members 7 of the connection rack 13 on a U-shape, and an extension line of the hook member 22 The left and right shelf frame side beam member receiving portions 23 are provided so as to extend below the left and right shelf frame side beam members 7 of another connection rack 13 that overlaps the upper portion of the connection rack 13. In the present embodiment, the hook member 22 is provided via a reinforcing member 24, and the left and right shelf frame side beam member receiving portions 23 are also formed by the reinforcing member 24.

  In the present invention, if the front shelf frame member 6a is constituted by the length between the left and right side beam members 2 of the connection rack 13, the same storage space can be obtained as when the connection racks 13 are arranged side by side. It is configured. The connection rack 21 is also provided with a stopper 20 similar to that of the other connection racks 13, so that the baggage placement racks do not fall inadvertently in the same manner as the connection racks 13 are arranged.

  Next, based on FIG. 3, the state which assembles many connection racks 13 using the connection shelf 21 for the connection racks 13 of this invention is demonstrated. When the connecting racks 13 are arranged side by side in the horizontal direction, the connecting racks 13 are not arranged adjacent to each other, but are arranged with a width corresponding to the connecting shelves 21, and the spaces between the connecting racks 13 are arranged. As shown in the figure, the connecting shelf 21 is connected to the left and right ends of the upper rack member 10a by hook members 22 that are hooked on the U-shaped parts of the connecting rack 13 from above the left and right shelf frame side beam members 7 and connected. By connecting (connecting) the racks 13 and the connecting racks 13, it is possible to secure a storage space as if the connecting racks 13 are arranged adjacent to each other.

  Due to the hook member 22 and its shape, not only when the connecting racks 13 are arranged adjacent to each other, but also when the connecting racks 13 are stacked and arranged, the left and right shelf frame side beam members 7 of the connecting rack 13 are arranged. The left and right side beam members 2 of the connecting rack 13 when stacked are formed in order to have the shape of the hook member 22 having a shape that covers the U-shape from the top and the left and right shelf frame side beam member receiving portion 23. By fitting in a form that can be fitted in the gap between the shelf frame side beam member receiving portion 23, the connection shelf 21 is configured to be securely held and connected. Even after the connection rack 13 is disposed in the lateral direction, the connection rack 21 is connected. The racks 13 can be stacked and arranged (the stacking state of the connecting racks 13 will be described later in FIG. 6), but the connecting shelf 21 is connected to the left side of the connecting rack 13 by a broken line. 21 Referring to the state illustrated click member 22, the right and left shelf frame Henhari member receiving portion 23 by a solid line).

  Naturally, in the place <upper> corresponding to the position of the connection shelf 21, when the first layer is a layer in which the connection racks 13 are horizontally arranged on the floor surface of a warehouse or the like, the connection racks 13 are connected in the same arrangement as the first layer. By arranging the connecting shelves 21 in order so as to interpolate the shelves 21 -the connecting racks 13... And the connecting racks 13, the connecting racks 13 are stacked in layers such as the first, second, and third layers. They can be placed one above the other.

  Therefore, even if the connecting racks 13 are disposed adjacent to each other in the horizontal direction or stacked in a stacked manner, the connecting racks 13 can be installed in the same manner, so that the number of the connecting racks 13 themselves can be greatly reduced. However, it is possible to secure an effective storage space.

  The connection rack 13 will be described in detail. When the connection racks 13 are stacked, the front part of the left and right side beam members 2 of the connection rack 13, that is, the portion where the width (W) of the front shelf frame member is shortened Stopper for stopping at an appropriate position when the racks 13 are stacked on the center rear part of the shelf frame member 9 constituting the upper rack member 10 of the rack 13. 20 is arranged.

  Accordingly, the stopper 20 is slid while the rear side beam member 4 of the upper portion of the connection rack 13 is slid on the left and right side beam members 2 of the lower side of the connection rack 13 in the vertical relationship where the connection racks 13 are stacked. The appropriate position in the front-rear direction is determined by the above, and the front part of the left and right side beam members 2 of the connection rack 13 described above, that is, the position where the width (W) of the front shelf frame member is shortened is (X ) Can be stacked in a state in which the connected racks 13 stacked in the vertical position are secured.

  On the other hand, at the time of storage, the front support column 11 is vertically connected vertically from the left and right ends of the front shelf frame member 6 via the support members 14 placed on the left and right side beam members 2, On the other hand, the rear column 12 is configured by vertically connecting the rear side beam member 4 placed on the rear side of the left and right side beam members 2 and the rear end of the left and right shelf side beam members 7 in the vertical direction. Even when 13 are nested (stacked and stored in a nested manner), the bottom rack member 5 of one linked rack 13 is stacked on the upper rack member 10 of another linked rack 13 to reduce the height direction when not in use. Can be stored. (See Figure 7)

  FIG. 5 depicts a state in which the connecting racks 13 are stacked in two layers on the stack, FIG. 5 (a) is a front view thereof, and FIG. 5 (b) is a right side view thereof. Similarly, FIG. 6 shows that the upper rack member 10 (lower) in the lower connecting rack 13 (lower) and the bottom rack member 5 (upper) in the upper connecting rack 13 (upper) in a state where the connecting racks 13 are two-tiered. (Top) Explanation of the plane of the part (In the drawing, each part appearing on the plane is indicated as (lower) for the members in the lower connecting rack 13 and (upper) for the upper members). FIG. 7 shows a state at the time of storage, and a state of nesting in four stages is drawn. Fig.7 (a) is the front view, FIG.7 (b) is a right view.

  5 and 6, the state in which the connecting racks 13 are stacked in two layers on the stack will be described. First, as shown in FIG. 6, the left and right side beam members of the upper connecting rack 13 (upper). The upper surface of 2 (upper) and the upper surface of the left and right shelf beam members 7 (lower) of the lower connecting rack 13 (lower) have the same height. Therefore, at least one or more of the left and right side beam members 2 (upper) and the left and right shelf side beam members 7 (lower) are fixed to the holes penetrating in the horizontal direction with the connecting means 40 (for example, pins, screws, wires). Thus, the structure is such that the upper and lower and the connected racks are not separated from the external force, and the rack can be prevented from falling off, which is safe. In the drawing, an example using screws and pins P is shown. Of course, other methods may be used as long as the same function can be achieved. For example, the above-described left and right side beam members 2 (upper) and the steel belt S can be used. The left and right shelf beam members 7 (lower) may be connected. Further, by using the steel belt S, it is possible to suppress the deviation by fixing the connecting racks 13 when they are arranged side by side. In short, the connecting means 40 may be arbitrarily selected or used in combination as long as it has an effect of preventing the shift. Further, when the connecting shelf 21 is arranged on the left side, it is a hole that penetrates at least one of the left and right side beam members 2 (upper) and the left and right side beam members 7 (lower) in the lateral direction. When fixing to the connecting means 40 with pins, screws, and wires, through holes are also formed in the left and right shelf frame side beam members (7a) of the connection shelf 21, so that the left and right side beam members 2 (upper) and the left and right shelf sides The beam member 7 (bottom) and the left and right shelf frame side beam members (7a) may be fixed integrally (not shown). Of course, the steel belt S may be fixed in a single unit, but in the case of a steel belt, at least the left and right side beam members 2 (upper) and the left and right shelf side beam members 7 (lower) of the connecting rack 13 are used. Fixing can firmly prevent vertical displacement.

  8 and 9 realize the adjustment of the connecting rack in the height direction. Actually, the tubular rear strut 12 can be easily made in the same manner as the tubular front strut 11 having a dimension arbitrarily set with respect to the inner dimension height of about 1500 mm, which is the current dimension, so that the length according to the application can be obtained. It is possible to obtain a storage environment corresponding to a desired height by appropriately combining the support columns.

  First, FIG. 8 will be described. FIG. 8A is a state before the operation, and FIG. 8B is a drawing after the operation. Struts are disposed at two positions on the support member 14 perpendicular to the bottom 1 direction from the front shelf frame member 6 or the reinforcing portion 30 disposed below it, while the tubular rear strut 12 Two points from the rear edge of the rear beam member 4 mounted on the rear part of the beam member 2 and the left and right shelf beam members 7, that is, from the upper rack member 10 to the rear beam member 4 vertically in the direction of the bottom 1. The connecting rack 13 is configured by placing the support column at the position and performing the processing of FIGS. 8A to 8B.

  Specifically, the location of the upper portion 8, that is, the front shelf frame member 6 or the reinforcing portion 30 disposed below it, the location where the upper rack member 10 is connected to the column, the location of the bottom portion 1, that is, the support member 14 and the rear portion. At the place where the support pillars of the side beam member 4 are connected, the connecting and coupling member 16 has a hollow cylindrical shape, and a screw groove 17 corresponding to the distal ends of the tubular front support pillar 11 and the tubular rear support pillar 12 is formed. By fitting and fixing the connected portion 31 and joining and fixing the connecting and coupling member 16 to the tubular front column 11 and the rear column 12 as depicted in the CC ′ cross-sectional view in FIG. The direction can constitute the connecting rack 13 determined by the length of the columns (11 and 12).

  In the present embodiment, four bolts and washers are used for connection by the connecting and connecting member 16, but there is no restriction on the number and location of the bolts and washers, and the material of the bolts and washers is not limited.

  The tubular front strut 11 and rear strut 12 are each constituted by a double pipe structure with the inner pipe 15 of the strut, and both are constituted by using a cylindrical member made of an iron material. By using a double structure, the strength can be improved even when the struts (11 and 12) are thin and light, so that the strength in the height direction is ensured while reducing the weight of the entire connecting rack 13. Can be realized.

  On the other hand, FIG. 9 is a diagram for explaining other four embodiments for coupling the coupling / coupling member 16 and the columns (11 and 12). FIG. 9 (a) is performed by welding 18, and FIG. 9 (b) is a diagram showing the connection by bolts and nuts, further simplifying the screwing shown in FIG.

  FIG. 9 will be described as another embodiment conceivable from FIG. 8, but the joining means by welding in FIG. 9 (a) is simple in its operation and requires only a short treatment time. Although it has the disadvantage that the workability for dismantling is poor, it can be said that it is the easiest coupling method as a result, since the connecting racks will not be dismantled semi-permanently once assembled.

  Further, the connecting method using bolts and nuts shown in FIG. 9 (b) is troublesome in that both the connecting connecting member 16 and the support columns (11 and 12) need only form sufficient through holes into which the bolts can be inserted. It can be said that it is a coupling method that can be easily disassembled in addition to assembling, while eliminating the need for such a thread groove (tapping). It should be noted that although there is no drawing of a nut on the bolt portion in FIG. 9B, it goes without saying that a loosening prevention process is performed as necessary.

  Moreover, although the load mounted on the upper rack member 10 normally uses a pallet P whose upper and lower surfaces are flat, there are times when the load is loaded via a pallet P with feet F provided on the lower surface so as to protrude several centimeters in height. is there. At that time, as can be seen from the arrangement of the desired shelf frame member 9 constituting the upper rack member 10, when the pallet P carrying the load to be loaded on the upper rack member 10 is mounted, the pallet P is placed, for example, back and forth. Even when the pallet P is displaced, the shelf frame member 9 can reliably hold the foot F of the pallet P. When the upper rack member 10 is viewed from above, the shelf frame members 9 existing in the regions A and B are viewed in the front-rear direction of the connection rack 13 as shown in the regions A and B before and after the upper rack member 10. By arranging them symmetrically with each other, the structure is such that the foot F of the pallet P can be reliably received and supported.

  Further, as shown in FIG. 10, in order to improve the rigidity of the connecting rack 13 itself, a tension adjusting member 41 (for example, a turnbuckle type brace used at a construction site) is arranged from the upper rack member 10 to the rear side beam member 4. By doing so, the rigidity of the whole connection rack can be improved by reinforcing the connection rack 13 with the force in the vertical direction. In this case, as shown in FIG. 10A, the tension adjusting member 41 is formed from the center of the upper rack member 10 to both ends of the rear side beam member 4, or as shown in FIG. The tension adjusting member 41 is formed from both ends of the upper rack member 10 to both ends of the rear side beam member 4. The base of each part of the tension adjusting member 41 is fixed by a stopper.

  As described above, the connection rack for the connection rack according to the present invention is simply arranged on the left and right in the conventional product, and only two connection racks are interposed, so the connection rack can be greatly reduced. Furthermore, since the coupling shelf is connected by the hook member and the left and right shelf frame side beam member receiving portions, the assembly efficiency is also greatly improved, and the coupling shelf is fixed securely and firmly. It will be useful.
