Description

  The present invention relates to a steel shelf and a wagon. In particular, the present invention relates to a shelf and a wagon for storing a heavy work tool such as a metal cutting blade. A steel shelf for storing such tools is generally called a rack.

  The steel shelf is composed of a shelf frame and a shelf board. The shelf frame is formed by bending a steel plate into a rectangular parallelepiped box or frame, and the shelf plate is formed by bending a steel plate into a rectangular box or plate having a right quadrilateral shape. In a steel shelf, usually a plurality of shelf boards are installed horizontally in a shelf frame. Each shelf is designed to allow an article to be placed thereon.

  When placing an article on a shelf board, it is preferable that the shelf board can be pulled out of the shelf frame. Similarly, when taking out articles placed on the shelf board, it is preferable that the shelf board can be pulled out from the shelf frame. For this reason, attempts have been made to make the shelf shelf movable so that the shelf plate can be pulled out or pushed in with the article placed on the steel shelf.

Japanese Patent Application Laid-Open No. 10-117860 describes a storage base in which a shelf board is movable with respect to a shelf frame. According to this description, in order to make the shelf plate movable, it is necessary to attach a plurality of slide rails in parallel, in which the slide rail is composed of an inner rail, an intermediate rail, and an outer rail. The rails are slidably engaged with each other. In particular, in this description, the rails, for example, the inner rails are connected to each other with a connecting tool to form a U-shaped integral, and then engaged with the intermediate rail and the outer rail that are also connected in a U-shaped manner. Yes. This slide rail fixes the inner rail to the shelf board and the outer rail to the shelf frame so that the inner rail can slide within the outer rail so that the shelf board can be moved relative to the shelf frame. .
Japanese Patent Laid-Open No. 10-117860

Similarly, Japanese Patent Application Laid-Open No. 8-19431 also describes an apparatus that allows a shelf board to move within a shelf frame. In the case of a shelf board, inner rails are attached to both sides of the shelf board, and an outer rail is attached to the shelf frame, and the inner rail and the outer rail are engaged with each other by sliding between the rails. The shelf board is movable. In this publication, a stopper is attached to the end of the inner rail in the length direction, the stopper is protruded by a spring, a hole is made in the outer rail, and the stopper is moved into the hole to move the shelf. Is proposed to temporarily stop.
Japanese Patent Laid-Open No. 8-19431

  In addition, a slide rack having a structure as shown in FIG. 1 is sold. The structure is such that the rail receiver A is fixed to the shelf frame, a roller B is attached to the lower portion of the rail receiver A, and the shelf plate C slides on the roller B. A shaft D is attached to the side surface of the shelf plate C, and the shaft D is rotatable by a handle E. Since the locking member F is attached to the shaft D and the locking member F is heavy, the shaft D is maintained in a state where the locking member F is always in contact with the rail receiver A. Accordingly, the shelf plate C stops moving when the locking member F collides with the protrusion G provided on the rail receiver A. However, when the shaft D is rotated, the locking tool F is lifted, so that the collision between the locking tool F and the protrusion G is released, and the shelf board C can move in the direction of the arrow H. In this way, the shelf board is temporarily prevented from popping out.

  In these shelves, the side from which shelves can be pulled out was only one side of the shelves. That is, Japanese Patent Laid-Open No. 10-117860 is intended for a closet or closet, and Japanese Patent Laid-Open No. 8-19431 is intended for a rice cooker in a rice storage box or a tray on which a keyboard of an OA device is placed. It is sufficient if the front can be pulled out to the alligator, so it has been structured to be pulled out to only one side. In addition, since the articles to be placed on these shelves are light, it is sufficient that the inner rail and the outer rail are engaged with each other, and there is no need to particularly consider reducing the friction between them. Also, because the shelf itself is stable, there is no risk that the shelf itself will fall even if the shelf board is pulled out greatly, so there is no need to attach a stopper, or even if a stopper is attached, the stopper has an inner rail on the outside. It was enough to prevent it from coming off the rail. Therefore, the stopper did not stop the drawer of the shelf on the way. Therefore, it is not suitable for storing a heavy article.

  The present invention is intended to provide a steel shelf that is suitable for storing a heavy tool such as a cutting tool for metal cutting and that is convenient for taking out and using the tool. Moreover, this invention provides a steel shelf as a steel wagon by attaching a caster to the lower end of such a steel shelf.

  This inventor needs to select and use a slide rail having a small sliding friction among the slide rails, which is suitable for storing the tool and convenient for taking out and using the tool. It is necessary to strictly limit the pull-out distance of the board, so it is necessary to be able to pull out the shelf board from the two opposite sides, and when the shelf board is stored, the shelf board is securely placed in the center of the shelf frame. I realized it was necessary to be.

  For this reason, in the present invention, as the slide rail, the inner rail and the outer rail come into contact with both sides in the width direction, and the steel balls are interposed on the contact surfaces, and both the rails slide by the rolling friction of the steel balls. It was decided to use the mechanism.

  In addition, since the tool is heavy, even if the shelf on which it is placed is pulled out slightly, the center of gravity of the shelf will move greatly, so there is a risk that the shelf will fall down. Cannot be pulled out of the shelf frame. Therefore, in the present invention, the shelf board can be pulled out from the two side surfaces of the shelf facing each other.

  In addition, as described above, when the shelf board jumps out of the shelf frame, the shelf may fall down, so that the shelf board needs to be strictly restricted. Therefore, in the present invention, a shaft extending parallel to the slide rail is rotatably attached to the shelf plate, a locking piece is attached to the shaft, and a fixing plate extending parallel to the shaft is attached to the shelf frame, A protrusion is attached to the fixing plate, and the locking piece is made to collide with the protrusion to prevent the shelf board from protruding.

  Further, when storing the tool, it is necessary that the shelf board is stored in the center of the shelf frame so that the steel shelf does not fall down even if some vibration is applied to the steel shelf. Therefore, in this invention, when the shelf board is located at the center of the shelf frame, the locking piece of the shaft collides with the protrusion of the fixed board to prevent the shelf board from moving.

  Further, in the present invention, a spring is attached to the shaft, and the spring rotates the shaft so that the locking piece attached to the shaft is always pushed toward the fixing plate with the protrusion. The movement of the shelf board was restrained by the piece colliding with the side surface of the protrusion. This collision can be easily released by turning a handle attached to the shaft.

  Thus, the present invention provides a steel shelf in which a slide rail is provided between a rectangular parallelepiped shelf frame and a rectangular quadrilateral shelf board accommodated in the shelf frame so that the shelf board can be moved within the shelf frame. In this case, a slide rail having a mechanism in which the inner rail comes into contact with and slides through the steel ball inside the outer rail is used to allow the shelf board to be pulled out from the two opposite sides of the shelf frame. A shaft extending parallel to the slide rail is rotatably attached to the plate, a locking piece projects from the central portion of the shaft in the longitudinal direction, and a fixed plate extending parallel to the shaft is attached to the shelf frame. , A protrusion is attached to each of the central portion and both ends of the fixing plate in the length direction, a spring is attached to the shaft, and the spring is urged to rotate the shaft and push the locking piece toward the protrusion, The locking piece collides with the side of the protrusion and moves the shelf. And wherein the obtaining, there is provided a steel shelves.

  The present invention also provides a steel wagon characterized in that a caster is attached to each of the four corners of the lower surface of the steel shelf as described above so that the steel shelf can be moved.

  In the present invention, since the slide rail has a mechanism in which the inner rail is in contact with and slides through the steel ball in the outer rail, the resistance at the time of sliding is less than that without the steel ball. Therefore, even when a heavy object such as a tool is placed, the shelf board can be moved with a small force.

  In addition, since the shelf plate can be pulled out from the two opposite side surfaces of the shelf frame, the tool stored on one side can be taken out from the near side surface, so that the tool can be easily removed and the shelf plate can be removed. There is no danger of tipping over the shelf frame.

  In addition, a shaft extending parallel to the slide rail is rotatably attached to the shelf plate, a locking piece is projected from the central portion in the longitudinal direction of the shaft, and a fixed plate extending parallel to the shaft on the shelf frame. Since the fixing plate is provided with a protrusion, the locking piece can be made to collide with the protrusion to reliably suppress the movement of the shelf, and the shaft can be rotated to release the collision between the locking piece and the protrusion. Thus, the shelf board can be easily moved.

  In addition, since the spring is attached to the shaft and the spring rotates the shaft and presses the locking piece toward the projection, the state where the locking piece collides with the side surface of the projection is maintained by the spring. Therefore, the movement of the shelf board is surely stopped.

  Furthermore, since the locking piece is provided in the central part of the shaft and the protrusion is provided in the central part of the fixing plate, when the shelf plate is located at the center of the shelf frame, the collision between the protrusion and the locking piece The movement of the shelf board can be surely suppressed. Similarly, since projections are provided on both sides of the fixed plate, excessive pulling of the shelf plate can be reliably suppressed by the collision between the projections and the locking pieces. As a result, the steel shelf can be prevented from falling.

  Also, if the projections attached to the central portion of the fixed plate are made as a pair of opposing projections, and there is a gap enough to put the locking piece between them, when the shelf plate is located at the center of the shelf frame Since the locking piece is sandwiched between the set of protrusions and cannot move, the shelf board is securely held at the center of the shelf frame. In addition, if the side surfaces facing the outside of the set of protrusions are gently inclined surfaces, the locking pieces can get over the inclined surfaces against the spring, so the shelf plate can be moved into the shelf frame without rotating the shaft. Can be pushed into.

  In addition, one protrusion is attached to each end of the fixed plate, the side face toward the center of each protrusion is a surface that stands upright with respect to the fixed plate, and the end of each protrusion is made to be a gently inclined surface. For example, when the shelf plate is pulled out to some extent, the locking piece collides with the upright surface of each projection, so that the shelf plate can be prevented from being pulled out. Because you can get over a gentle slope against the spring, you can push it in as it is.

  In addition, the wagon according to the present invention can be easily carried to a necessary place in a state where a heavy tool is stored, and the tool can be easily taken out from any side of the two sides at that place. is there.

  The present invention provides such an effect.

  An example of the embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a perspective view of a steel shelf according to the present invention. FIG. 3 is a partially cutaway perspective view of a slide rail used in the present invention. FIG. 4 is a partially cutaway perspective view of a steel shelf according to the present invention. FIG. 5 is an explanatory view showing the relationship between the shaft and the fixing plate used in the present invention. FIG. 6 is a partially cutaway perspective view of a tool stand placed in a shelf board in the steel shelf according to the present invention. FIG. 7 is a perspective view of a steel wagon in which casters are attached to the lower end of the steel shelf according to the present invention.

  As shown in FIG. 2, the steel shelf according to the present invention includes a rectangular parallelepiped shelf frame 1 and rectangular quadrilateral shelf plates 2 and 3 housed in the shelf frame 1. The shelf 2 is plate-shaped, but the shelf 3 is in a shallow box shape. Although not shown in FIG. 2, the slide rail 4 shown in FIG. 3 is attached between the shelf frame 1 and the shelf plate 2 or 3, and the shelf plates 2 and 3 move within the shelf frame 1. It is possible.

  As shown in FIG. 3, the slide rail 4 is configured such that the inner rail 42 can slide through the steel balls 43 in the outer rail 41. Since the steel balls 43 are interposed, both ends in the width direction of the outer rail 41 are curved inward, and both ends in the width direction of the inner rail 42 are curved outward. The steel ball 43 is accommodated in these two opposing curved portions. The inner rail 42 and the outer rail 41 are in close contact with each other via a steel ball 43, and are kept in a state that does not rattle. For this reason, the inner rail 42 is in a state in which it can slide within the outer rail 41 with a slight force.

  In the slide rail 4, in order to prevent the inner rail 42 from coming off the outer rail 41 and to prevent the steel ball 43 from escaping from the curved portion, both the outer rail 41 and the inner rail 42 are both ends in the length direction. Has a unique shape. For example, as shown in FIG. 3, the inner rail 42 is erected so that the end 421 protrudes to the curved portion.

  The slide rail 4 fixes the outer rail 41 to the shelf frame and the inner rail 42 to the shelf frame so that the shelf plate can be moved with respect to the shelf frame. At this time, the inner rail 42 is preferably fixed directly to the side surface of the shelf board 3 as shown in FIG. 4, but the outer rail 41 is preferably fixed to the shelf frame 1 via the fixing plate 5.

  As shown in FIG. 4, a shaft 6 extending in parallel with the slide rail 4 is attached to the shelf board. Therefore, in FIG. 4, the fixing metal fitting 61 is attached to each corner of the side surface of the shelf board 3 which exhibits a shallow box shape. A hole is formed in a portion of the fixing bracket 61 that protrudes upward from the shelf plate 3, and the shaft 6 is passed through the hole so that the shaft 6 can rotate. Both ends of the shaft 6 are bent in an L shape to constitute a handle 62. The shaft 6 is rotatable by the handle 62.

  A standing piece 611 protrudes from the lower portion of the fixing metal 61, and an upright piece 64 protrudes from the shaft 6 at a portion located outside the fixing metal 61. The standing piece 64 protrudes in the extending direction of the handle 62 with respect to the shaft 6. A spring 7 is attached between the upright piece 611 and the upright piece 64 to pull the gap therebetween. For this reason, the shaft 6 is biased to rotate clockwise in FIG.

  A locking piece 63 is attached to the central portion of the shaft 6 in the length direction. The locking piece 63 stands substantially parallel to the standing piece 64. Therefore, the locking piece 63 is pressed against the fixed plate 5 by the spring 7.

  As shown in FIG. 4, the fixing plate 5 to which the outer rail 41 is fixed surrounds the outer rail 41 and is fixed to the shelf frame 1. Accordingly, the fixing plate 5 extends in parallel with the shaft 6 along with the shaft 6. As shown in FIG. 5, protrusions 51, 52, 53, and 54 are attached to the center portion and both ends of the fixing plate 5 in the length direction. Therefore, when the shelf plate 3 moves, the locking piece 63 moves along the fixed plate 5 and comes into contact with the protrusions 51 to 54.

  As shown in FIG. 5, projections 51 and 52 are provided in pairs at the center portion of the fixing plate 5, and a gap is provided between the projections 51 and 52 just between them. In addition, the protrusions 51 and 52 have inner side surfaces facing each other upright with respect to the fixing plate 5, and the outer surface located on the opposite side is an inclined surface that gradually decreases toward the end. For this reason, when the shaft 6 moves toward the protrusions 51 and 52, the locking piece 63 resists the spring 7 and can get over the protrusion and enter the interval. However, when the locking piece 63 enters the interval, the locking piece 63 cannot escape from the gap unless the shaft 6 is rotated. Therefore, the shelf board is stably and reliably held at the center of the shelf frame.

  As shown in FIG. 5, protrusions 53 and 54 are attached to both ends of the fixing plate 5. In each of the protrusions 53 and 54, a side surface facing the center portion of the fixing plate 5 is a surface that stands upright with respect to the fixing plate 5, and a surface facing the end of the fixing plate 5 is a gentle inclined surface. Therefore, the locking piece 63 is locked at the end of the fixed plate 5 by the projection 53 or 54 and cannot be released unless the shaft 6 is rotated. For this reason, the movement of the shelf plate is surely stopped when it moves to some extent from the shelf frame. However, when the shelf board is inserted into the shelf frame, the locking piece 63 can get over the protrusion 53 or 54, so that the insertion is easy. It is preferable that the protrusion 53 and the protrusion 54 are provided at a position where the shelf board 3 is pulled out by a length of one-half to two-thirds of the depth of the shelf board 3.

  As shown in FIG. 5, the fixing plate 5 includes fixing pieces 56 and 57 at both ends in order to facilitate fixing to the shelf frame. Each of the fixing pieces 56 and 57 has a claw-like cut at the end that is in close contact with the shelf frame, and the claw portion is slightly bent to provide a locking gap between the claw portion and the remaining portion. Is. The fixed piece 56 has a gap in the longitudinal direction of the fixed plate 5, while the fixed piece 57 has a gap in the width direction of the fixed plate 5. For this reason, the fixing plate 5 is simply fixed to the shelf frame 1 by first inserting the fixing piece 56 into the notch 11 of the shelf frame 1 and then inserting the fixing piece 57 into the notch 12 of the shelf frame 1. be able to.

  Thus, the steel shelf according to the present invention can store the article in a stable state by placing the article on the shelf board, and when necessary, the shelf board can be half or three minutes deep from the appropriate side. By simply pulling out the length of 2, the article can be taken out, so that the article can be safely stored without fear of overturning the steel shelf.

  When storing a tool such as a metal cutting blade, it is preferable to use a shallow box as a shelf. This is because if a shallow box-shaped shelf board is used, a rectangular tool stand 8 as shown in FIG. 6 can be spread in the box and stored without colliding each tool.

  The tool stand 8 is formed by bending a steel plate into a U-shape in cross section, opening a plurality of round holes at intervals on a central surface 81 located at the center of the U-shape, and synthetic resin in the round holes. A cylinder 82 made of steel is fixed. The cylinder 82 made of synthetic resin is narrower on both the inner surface and the outer surface, and step portions 821 and 822 are formed in the middle. The step 821 is for fixing the cylinder 82 to the central surface 81, and the step 822 is for locking the tool.

  The tool stand 8 is spread in the shelf board 3 without a gap with the width direction directed to the moving direction of the shelf board 3. The tool is stored safely by standing in the cylinder 82 with the cutting edge facing up.

  Moreover, the above-mentioned steel shelf can be made into a steel wagon by attaching casters to the four corners of the lower surface. An example of a steel wagon is shown in FIG.

  The steel wagon 9 shown in FIG. 7 has a caster 91 attached to the lower surface of a steel shelf made by attaching a shallow box-like shelf board 3 to the shelf frame 1 by a slide rail. In FIG. 9, the slide rail and the shaft are omitted for the sake of simplicity, but these are naturally attached.

  In the steel wagon 9, a handle 92 for moving the wagon is attached to the shelf frame 1. The surface located on the opposite side of the surface on which the handle 92 is provided is constituted by a flat plate 93 having a large number of small holes. This small hole is used to hang a small item by hooking a hook.

  The upper shelf of the wagon 9 is in a state excluding a tool stand in order to show that the shelf 3 is in a shallow box shape, but in fact, like the lower shelf 3 The tool stand 8 is spread and used. The lower shelf 3 is in a state where it is pulled out from one side of the shelf frame 1, and shows a state where the tool is stored in a cylinder 82.
