Description

  The present invention relates to a combination of a plate and a spacer, particularly a spacer capable of accommodating a long member, and a movable gate provided with this combination.

  Conventionally, when a long member is mounted on a plate, the long member is directly fitted into a mounting groove formed in the plate (Patent Document 1).

  On the other hand, in order to load and unload cargo on the cargo bed of the vehicle, it is equipped at the rear or side of the vehicle, and either or both the worker and the cargo are loaded on the floor plate and this is placed on the ground and the floor of the cargo bed. A movable gate that moves up and down between the gates is widely used (Patent Document 2).

JP 2012-2009029 A Patent No. 3409839

  As shown in Patent Literature 1, when the long member is directly fitted into the mounting groove formed in the plate, if the long member is fixed to the plate in the mounting groove, the long member is elongated. The member cannot be easily taken out from the mounting groove (the workability at the time of removal is extremely poor). Further, when the long member is removed from the mounting groove, the mounting groove is exposed, and a worker or a pedestrian moving on or around the plate may trip over or get caught in the mounting groove and fall. If the mounting groove is maintained in an exposed state, rainwater, dust and the like accumulate in the exposed mounting groove, which is not preferable in terms of hygiene and appearance, and furthermore, the long member can be re-mounted in the mounting groove. There is a possibility that it will disappear.

  In order to avoid the state where the mounting groove is exposed after the long member is removed from the mounting groove, a spacer for filling the mounting groove from which the long member has been removed may be mounted. is there. Such a spacer is a member that is usually used only when filling the mounting groove. When the spacer is not used, that is, when the long member is mounted in the mounting groove, the spacer is removed from the mounting groove and is not used. Stored in the place. For this reason, when the spacer is removed from the mounting groove, there is a risk that the spacer will be lost, and it is necessary to secure a space for storing the spacer.

  On the other hand, in the movable gate disclosed in Patent Literature 2, when a worker works at night or in a dark place on a floor plate on which a receiving surface is formed, the worker operates the outer peripheral portion of the floor plate. May not be recognized, and one or both of the worker and the cargo may fall off the floor plate.

  Here, the long member in Patent Literature 1 is a luminous body, and in Patent Literature 1, the luminous body is mounted on the outer peripheral edge of a tread (plate) of a ladder vehicle to emit light, so that the luminous body is used at night or in a dark place. However, the position of the outer peripheral edge of the tread plate is clearly indicated to the worker working on the tread plate, so that the worker is prevented from falling off the tread plate. From this, the above-mentioned problem in Patent Document 2 can be solved by mounting a light emitting body on the outer peripheral edge of the floor plate. However, anyone who uses the movable gate can use the floor plate at night or in a dark place. They do not always work on the floor, and some only work on the floor plate in the daytime or in bright places. Since the luminous body usually uses electrical parts, wiring is troublesome, and it is necessary to construct a control system for controlling the luminous body. The price of movable gates will also rise. A luminous body is not required for those who work on the floor plate only in the daytime or in a bright place, and such a person requires a lower-cost movable gate without the luminous body. From such a demand, it is conceivable to prepare two types of movable gates in advance depending on the presence or absence of the light-emitting body (that is, the mounting groove). However, two types of movable gates are separately prepared from the viewpoint of manufacturing cost. That is undesirable. In addition, when the illuminant is not required, it seems that only the illuminant may be simply removed from the floor plate. However, if only the illuminant is simply removed from the floor plate, the mounting groove is exposed. The same problem occurs when the measuring member is removed.

  The present invention has been made in view of the above facts, and a main technical problem thereof is to provide a combination of a plate and a spacer in which a spacer is mounted in a mounting groove regardless of the presence or absence of a long member. And to provide a movable gate with this combination.

  As a result of intensive studies, the present inventors have found that the main technical problem can be solved by forming both the cross section of the mounting groove of the plate and the cross section of the spacer into a U-shape.

That is, according to the present invention, a combination of a plate and a spacer attached to the plate,
The plate includes a mounting groove extending along a predetermined direction and having a U-shaped cross section.
The spacer extends along the predetermined direction, and a cross section of the spacer has a U-shape including a bottom wall and a pair of side walls extending from both side edges of the bottom wall and facing each other. A long member can be accommodated in the inner space formed by the inner surface of the pair and the inner surfaces of the pair of side walls,
When the spacer is mounted in the mounting groove such that the inner surface of the bottom wall faces the bottom surface of the mounting groove, the outer surface of the bottom wall is in contact with a portion of the plate where the mounting groove is not formed. Become one
When the spacer is mounted in the mounting groove such that the outer surface of the bottom wall faces the bottom surface of the mounting groove, the inner space is exposed, and a combination of a plate and a spacer is provided. Is done.

  Preferably, locking means cooperating with each other is formed on a side surface of the mounting groove and an outer surface of the side wall. Preferably, an engagement ridge that engages with the elongated member is formed on an inner surface of the side wall. When viewed in the predetermined direction, a terminal cap is fixed to an end of the elongate member, and the terminal cap is elastically fitted into the mounting groove adjacent to an outer end of the spacer viewed in the predetermined direction. Is good. The long member can be a light emitting body. In this case, when the spacer is mounted in the mounting groove while the luminous body is housed in the inner space portion, the outer surface of the bottom wall faces the bottom surface of the mounting groove, Preferably, the luminous body is exposed. When the long member is a luminous body, the bottom wall has a function of passing light emitted from the luminous body, the spacer is provided in the mounting groove, and the luminous body is provided in the inner space. In the housed state, the bottom wall may be mounted such that the inner surface of the bottom wall faces the bottom surface of the mounting groove via the light emitting body. In this case, the function of transmitting the light of the bottom wall can be realized by forming the bottom wall with a synthetic resin having light transmittance. At this time, the light transmitting synthetic resin may attenuate the amount of light from the light emitting body. The function of transmitting light of the bottom wall may be realized by forming a slit or a hole in the bottom wall.

  Further, according to the present invention, a movable gate mounted on a vehicle having a loading platform and moved up and down between the ground and the floor surface of the loading platform, comprising a combination of the above-described plate and spacer. Is provided.

  In the combination of the plate and the spacer configured according to the present invention, the inner surface of the bottom wall is formed on the bottom surface of the mounting groove because the cross section of the mounting groove of the plate and the cross section of the spacer are both U-shaped. The spacer can be mounted on the plate in such a manner as to face the mounting member, and the mounting groove can be prevented from being exposed on the plate even when the long member is not mounted on the mounting groove. Further, at this time, since the outer surface of the bottom wall is flush with the portion of the plate where the mounting groove is not formed, there is no step due to the mounting groove on the plate, and the worker or passerby stumbles on the plate. It is prevented as much as possible from getting stuck. On the other hand, when the spacer is mounted on the plate such that the outer surface of the bottom wall faces the bottom surface of the mounting groove, an inner space formed inside the spacer is exposed on the plate. Therefore, the long member can be mounted in the mounting groove without removing the spacer from the mounting groove, and there is no need to secure the space for storing the spacer and the risk of losing the spacer. When the long member is removed from the mounting groove, the spacer may be removed from the mounting groove together with the long member, and the workability is improved.

  Hereinafter, with reference to the accompanying drawings, preferred embodiments of a combination of a plate and a spacer configured according to the present invention and a movable gate including the same will be described in further detail. In the following description, the front, rear, left, right, up, down, and inward and outward directions are based on the vehicle traveling direction in a state in which a later-described floor plate of the movable gate is deployed (a state shown in FIG. 1) unless otherwise specified.

  Referring to FIG. 1, a movable gate, generally designated by reference numeral 1, is disposed at a rear end portion of a vehicle having a loading platform, and is capable of moving up and down a floor plate 2 by a drive device described later, and standing upright. (Not shown) and a state where it is deployed rearward (the state shown in FIG. 1). The floor plate 2 includes a main portion 4 which is a flat plate member having a rectangular shape as a whole, and side guards 6 extending linearly in the front-rear direction at both side edges of the main portion 4. A substantially flat loading surface 8 is defined on the upper surface of the main part 4. At the rear edge of the receiving surface 8, a drop prevention stopper 9 extending linearly in the left-right direction is provided. The fall prevention stopper 9 is selectively rotatable between a state in which the upper surface is substantially flush with the load receiving surface 8 and a state in which the stopper 9 stands up with respect to the load receiving surface 8, and when in the former state, The carriage and the like are allowed to pass on the receiving surface 8, and in the latter state, the passage of the carriage and the like is restricted. Since such a fall prevention stopper 9 is a well-known technique, a detailed description thereof will be omitted in this specification.

  At the front edge and the rear edge of the receiving surface 8, there are formed linear mounting grooves 10 extending parallel to each other in the left-right direction (the mounting grooves formed at the rear edge of the receiving surface 8). 10 is located somewhat forward of the fall prevention stopper 9). As can be understood by referring to FIGS. 2 and 6 together with FIG. 1, the mounting groove 10 is provided over the entire load receiving surface 8 when viewed in the left-right direction, and both side ends thereof are hidden by the side guard 6. I have. Referring to FIGS. 3 and 4, the cross section of the mounting groove 10 has a U-shape with an open top, and one of a pair of opposing side surfaces projects toward the other side surface. Two locking ridges 11 are formed at an interval in the vertical direction (each is indicated by reference numerals 11a and 11b). If desired, the locking ridges 11 may be formed on both of the pair of side surfaces, respectively.

  As shown in FIGS. 2 to 4, a long member is mounted in the mounting groove 10 via a spacer 12. In the illustrated embodiment, the elongate member is the light emitter 14, and the light emitter 14 is linear with the spacer 12. The luminous body 14 will be described with reference to FIG. 5, which is a simplified schematic diagram thereof. 5A is a plan view of the light emitting body 14, FIG. 5B is a front view of the light emitting body 14, and FIG. 5C is a cross-sectional view of the light emitting body AA. The luminous body 14 extends in the longitudinal direction and has a rectangular casing 16, a thin board 18 extending in the longitudinal direction inside the casing 16, A light emitting element 20 is provided, and a power cable 22 for supplying power to the light emitting element 20 via a board 18 from a battery (not shown) mounted on a vehicle. The housing 16 is made of a relatively soft synthetic resin, and is substantially colorless and transparent as a whole. End caps 24 are fixed to both ends of the housing 16 when viewed in the longitudinal direction. The end cap 24 has a rectangular parallelepiped shape slightly larger than the cross section of the mounting groove 10, and is formed of a synthetic resin material having elasticity, and prevents liquid from entering the inside from the longitudinal end face of the housing 16. A power cable 22 passes through one end cap 24 (see also FIG. 6). The light emitting element 20 is an appropriate point light source such as an LED or a light bulb, and its color temperature may be arbitrary. Such a light-emitting body 14 is formed as a so-called core when the housing 16 is formed together with the substrate 18 with the light-emitting element 20 to which the power cable 22 is connected in advance. If desired, the light emitting element 20 is exchangeably disposed in a suitable socket provided on the surface of the housing 16 instead of being irreplaceably disposed (ie, buried) in the housing 16. You may make it so. Further, the light emitting element 20 may be a linear light source such as a neon tube instead of a point light source.

  2 to 4, the spacer 12 is made of a relatively hard synthetic resin or a metal such as aluminum, and has a length in the longitudinal direction of the housing 16 of the light-emitting body 14. It is equal to the length and somewhat shorter than the length of the mounting groove 10 in the left-right direction. The cross section of the spacer 12 is formed by extending from the bottom wall 26 and both side edges of the bottom wall 26 (upward in the state of FIGS. 3 and 4 and downward in the state of FIG. It has a U-shape including a pair of side walls 28 facing each other. In the spacer 12, an inner space portion 30 capable of accommodating a long member (in the illustrated embodiment, the light emitter 14) is formed by the inner surface 26a of the bottom wall 26 and the inner surfaces of the pair of side walls 28. On each outer surface of the pair of side walls 28, two locked ridges 32 are formed at an interval in the vertical direction (each is indicated by a number 32a and 32b). The locked ridge 32 cooperates with the locking ridge 11 formed on the side surface of the mounting groove 10 to constitute locking means. Further, two engagement protrusions 34 are formed on the inner surfaces of each of the pair of side walls 28 at intervals in the vertical direction. If desired, an engaged ridge is formed on the outer peripheral surface of the housing 16, and the engaged ridge and the engaging ridge 34 cooperate with each other to form an engaging means. Is also good.

  In the illustrated embodiment, the light-emitting body 14 is housed in the inner space 30 of the spacer 12 in a state where the housing 16 is elastically held by the engaging ridges 34. At this time, since the lengths of the spacer 12 and the light emitter 14 in the longitudinal direction are the same, as shown in FIG. 2, the end cap 24 is located adjacent to the outer end of the spacer 12 viewed in the left-right direction. In the embodiment shown in FIG. 1, the spacer 12 is forcibly mounted in the mounting groove 10 with the outer surface 26 b of the bottom wall 26 facing the bottom surface 10 a of the mounting groove 10. At this time, the locked ridge 32b elastically rides over the locking ridges 11a and 11b and is locked by the locking ridge 11b, so that the spacer 12 is prevented from falling out of the mounting groove 10. As shown in FIG. 2, the end cap 24 is fitted into the mounting groove 10 at both ends of the mounting groove 10 viewed in the left-right direction, and is elastically held by the locking ridge 11. Then, in a state where the spacer 12 in which the light emitting body 14 is housed is mounted in the mounting groove 10, the light emitting body 14 housed in the inner space 30 is exposed on the floor plate 2.

  Continuing the description with reference to FIG. 6 together with FIG. 1, in the illustrated embodiment, the luminous body 14 is also mounted on the side guard 6. The side guard 6 includes a mounting portion 36 that sandwiches the side edge of the main portion 4 from above and below and is fixed thereto, and an upright wall 38 that rises upward from the inner edge of the mounting portion 36 as viewed in the left-right direction. I have it. The upright wall 38 includes a lower base end portion 40 extending upward from the attachment portion 36, an intermediate portion 42 extending inward as viewed from the upper end of the lower base end portion 40 in the left-right direction, and an intermediate portion viewed in the left-right direction. And an upper main portion 44 extending upward from an inner end of the portion 42. For this reason, the side guard 6 has a lower base end portion 40, an intermediate portion 42, and an inner end portion of the mounting portion 36 as viewed in the left-right direction. A letter-shaped mounting groove 46 is formed. The mounting groove 46 has the same configuration as the above-described mounting groove 10 except that it is opened inward when viewed in the left-right direction. The light-emitting body 14 is also mounted on the mounting groove 46 via the spacer 12 described above. Be attached. The mounting of the luminous body 14 in the mounting groove 46 via the spacer 12 is the same as the mounting in the mounting groove 10, and a description thereof will be omitted.

  FIG. 1 also shows a vehicle 48 to which the movable gate 1 of the present invention is mounted by a two-dot chain line. Although illustration of the entirety of the vehicle 48 is omitted, the vehicle 48 is a vehicle for transporting cargo on which a box-shaped carrier 49 is mounted, and includes a pair of main frames 50 extending in the front-rear direction. An end frame 52 extending in the left-right direction is provided at the rear end of the main frame 50. The movable gate according to the present invention includes the floor plate 2 and an elevating device 54 for operating the floor plate 2. 1 is provided. The floor plate 2 is stored in the vehicle near the rear surface of the loading platform 49 or as a part of the rear surface of the loading platform 49 in a state where the floor plate 2 stands upright with respect to the ground, and is deployed and used in a state parallel to the ground. . The structure of the vehicle 48 and the operation of the movable gate 1 provided on the vehicle 48 are well known, and a detailed description thereof will be omitted.

  In the movable gate constructed according to the present invention, when the luminous body 14 is mounted on the floor plate 2 via the spacer 12 as described above, the luminous body 14 may be at night or in a dark place due to the presence of the luminous body 14. However, the presence of the floor plate 2 is clearly displayed to the worker who works on the floor plate 2, and one or both of the worker and the cargo are prevented from falling off the floor plate. In the illustrated embodiment, since the mounting grooves 10 and 46 are both provided on the outer peripheral edge of the floor plate, the position of the outer peripheral edge of the floor plate is clearly displayed to the operator.

  In the movable gate configured according to the present invention, the light-emitting body 14 as a long member can be removed from the floor plate 2 according to a user's request or the like. At this time, since the luminous body 14 is not directly fitted into the mounting grooves 10 and 46 but is indirectly fitted via the spacer 12, the luminous body 12 does not adhere to the mounting grooves 10 and 46. In some cases, the luminous body 14 is fixed to the spacer 12 in the mounting grooves 10 and 46. When the luminous body 14 is fixed to the spacer 12 in the mounting grooves 10 and 46, the luminous body 14 may be removed from the spacer 12 after removing the spacer 12 together with the luminous body 14 from the mounting grooves 10 and 46. . At this time, the light emitter 14 can be easily removed from the spacer 12 by appropriately deforming the spacer 12 by applying a force. On the other hand, if the light emitting body 14 is directly fitted into the mounting groove and fixed thereto, it is difficult to remove the light emitting body 14 from the mounting groove because it is impossible to deform the mounting groove itself. Become.

  When the luminous body 14 is removed from the floor plate 2, as shown in FIG. 7, the spacer 12 is mounted in the mounting groove 10 such that the inner surface 26a of the bottom wall 26 faces the bottom surface 10a of the mounting groove 10. At this time, the locked ridge 32a elastically crosses the locking ridges 11a and 11b and is positioned below them, and the locked ridge 32b elastically crosses the locking ridge 11a. The spacer 12 is prevented from coming off from the mounting groove 10. By mounting the spacer 12 in the mounting groove 10 as described above, the mounting groove 10 is not exposed on the floor plate 2 even when the light emitter 14 is not mounted in the mounting groove 10. Further, at this time, the outer surface 26b of the bottom wall 26 is flush with a portion of the floor plate 2 where the mounting groove 10 is not formed. As a result, it is possible to prevent a worker or a pedestrian from tripping or getting stuck on the floor. Similarly, when the luminous body 14 mounted on the side guard 6 is removed, the luminous body 14 is mounted in the mounting groove 46 such that the inner surface 26 a of the bottom wall 26 faces the bottom surface of the mounting groove 10. Thus, this is prevented from being exposed.

  In the above-described embodiment, when the spacer 12 in a state where the luminous body 14 is housed in the inner space 30 is mounted in the mounting groove 10, the outer surface 26 b of the bottom wall 26 is attached to the bottom surface 10 a of the mounting groove 10. It was attached so that it might face. However, when the bottom wall has a function of transmitting light from the light emitter, as shown in FIG. 8, the spacer 12 'is accommodated in the mounting groove 10 and the light emitter 14 is accommodated in the inner space 30'. The mounting can also be performed such that the inner surface 26 a ′ of the bottom wall 26 ′ faces the bottom surface 10 a of the mounting groove 10 via the light emitting body 14.

  The function of allowing the light of the bottom wall 26 'to pass therethrough is realized by forming the bottom wall 26' with a light-transmitting synthetic resin. In the spacer 12 'shown in FIG. 8, the entire spacer 12' including the bottom wall 26 'is formed of a light-transmitting synthetic resin, and is substantially transparent. Therefore, the light amount from the light emitter is transmitted to the outside through the bottom wall 26 'with almost no attenuation. Accordingly, the luminous body 14 emits light while being covered with the spacer 12 ′ without being exposed to the outside, so that the luminous body 14 can be effectively protected from external impact, dust, dust, or the like. Thus, the service life of the light emitting body 14 can be extended.

  The light-transmitting synthetic resin described above may attenuate the amount of light from the light emitter 14. In this case, the bottom wall 26 '(in the embodiment shown in FIG. 8, the entire spacer 12' including the bottom wall 26 ') becomes translucent, and the bottom wall 26' reduces the light amount from the light emitter 14 to a predetermined degree. Attenuate and transmit. The attenuation of the amount of light from the light emitter 14 by the bottom wall 26 'is preferably 10 to 90%, more preferably 30 to 70%, depending on the type of synthetic resin used and the thickness of the bottom wall 26'. Are set by appropriately adjusting. Attenuating the light amount from the light emitter 14 is desired when the light amount from the light emitter 14 is excessively large. In this case, when the light from the light emitter 14 passes through the bottom wall 26 ', the light is diffusely reflected and diffused therein, so that the so-called glare of the light passing through the bottom wall 26' is reduced, An anti-glare effect is obtained that is more than simply reducing the amount of light.

  When the bottom wall 26 'does not have light transmittance (that is, when the bottom wall 26' is formed of a non-light-transmitting synthetic resin or a metal such as aluminum), as shown in FIG. By forming a slit 56p 'or a plurality of holes 56q' in 26 ', the bottom wall 26' can have a function of transmitting light from the light emitter 14. In the spacer 12p 'shown in FIG. 9A, the slit 56p' extends linearly in the longitudinal direction, and penetrates from the outer surface 26b 'of the bottom wall 26' to the inner surface 26a '. In the spacer 12q 'shown in FIG. 9B, a large number of circular holes 56q' are arranged at equal intervals in the longitudinal direction. Each hole 56q 'penetrates from the outer surface 26b' of the bottom wall 26 'to the inner surface 26a'.

  The combination of the plate and the spacer of the present invention and the movable gate provided with this combination have been described in detail with reference to the accompanying drawings. However, the present invention is not limited to such an embodiment, and the scope of the present invention is not limited thereto. Various changes and modifications are possible without departing from the scope of the invention. For example, in the present embodiment, the mounting groove, the spacer, and the long member are all linear, but they may be curved. Further, although the spacer and the long member are provided over the entire mounting groove, the spacer and the long member may be provided only on a part of the mounting groove instead. Furthermore, the combination of the plate and the spacer according to the present invention is not limited to being applied only to the movable gate, but can be arranged on various floor surfaces such as a staircase of a building or an outer peripheral edge of a cargo bed. Further, the plate is not limited to being arranged on the floor, but may be arranged on the side surface or the top surface.
