Reference numeral 31 denotes a corner member that connects the corners of the left and right edge members and the upper and lower edge members. These edge members and corner members may be made of synthetic resin. Further, a projection 34 for a movement restricting body 33 described later is formed on the lower end surface of the corner member 31 so as to project downward.
[0010]
Rollers 32, 32 are embedded in the lower edge member 27 of each board 7 at appropriate intervals on the left and right, and roll along the upper surfaces of the ridge rails 18.
[0011]
Next, the movement restricting means of the boards 7, 7 of the present invention will be described. The first embodiment is, as shown in FIGS. 4 to 8, a movement restricting body 33 having an end cover portion 33 a for mounting so as to close an end portion of the lower guide rail 9, and the base 33 b has the pair of movement restrictors 33. The rail insertion grooves 35, 35 for receiving the protruding rail portions 18, 18 are recessed, and a mounting screw hole 36 formed in a lateral direction of the base 33a and a lateral hole formed in the protruding rail portion 18. The movement restricting body 33 and the lower guide rail 9 can be fixed so that they cannot be disengaged by inserting a bolt 39 through 40 (see FIGS. 4, 5, and 7).
[0012]
Further, two elastic pieces 38 are integrally formed from the base 33b so as to protrude following the recess 37 into which the protrusion 34 is fitted. Each elastic piece 38 extends so as to be disposed along a guide groove 9b between the pair of projecting rail portions 18, 18 and the side edges 9a, 9a of the lower guide rail 9, and each elastic piece 38 is free. Only the lower surface of the end 38a can contact the bottom plate 9c of the lower guide rail 9, and the upper surface of each elastic piece 38 has a substantially horizontal top surface 38b in the middle of its longitudinal direction (longitudinal direction of the ridge rail 18). The top surface 38b is connected to the upper end of the free end 38 and the recess 37 by downward inclined surfaces 38c and 38d. The movement restricting body 33 and thus the elastic piece 38 are formed of an elastic material such as nylon resin (see FIG. 5).
[0013]
According to the movement restricting body 33 having this configuration, when each board 7 is moved to the end along the upper and lower guide rails 8 and 9, the projection 34 at the lower end corner of the board 7 is moved from the inclined surface 38 c of the elastic piece 38 to the top surface. As the elastic piece 38 is pressed downward as it approaches the surface 38b, the elastic piece 38 is elastically deformed downward by its own elastic force to apply a brake to the movement of the boat 7 (the two-dot chain line state in FIG. 4). reference). Then, when the protrusion 34 gets over the top surface 38b, the elastic piece 38 and the elastic restoring force of the elastic piece 38 return to the solid line state in FIG. Can be stopped. Even when the protrusion 34 located in the recess 37 gets over the top surface 38b from the inclined surface 38d side, it receives the resistance due to the elasticity of the elastic piece 38 in the same manner as described above. When writing characters or the like, the board 7 does not climb over the elastic piece 38 with a light force caused by the friction, so that the board 7 can be restricted from moving along the guide rails 8 and 9. Therefore, the scribe can write characters and the like in a stable state.
[0014]
FIGS. 9 and 10 show a second embodiment of the movement restricting means, in which the guide groove 9b between the ridge rail portion 18 and the side edges 9a, 9a before or after the lower guide rail 9 is located in the middle part in the longitudinal direction. The movement restricting body 41 which is arranged so as to extend along and is fixed via a screw 42 has a pair of elastic pieces 38 integrally formed so as to protrude in opposite directions from a recess 43 at the center in the longitudinal direction. At the recess 43, a screw 42 is screwed to the bottom plate 9c of the lower guide rail 9. Further, since each elastic piece 38 has substantially the same shape as that of the first embodiment, the same portions are denoted by the same reference numerals and detailed description thereof will be omitted.
[0015]
According to this embodiment, it is easy to fit the projections 34 of the boards 7 into the recesses 43 at the installation location of the movement restricting body 41 fixed to the middle part in the longitudinal direction of the lower guide rail 9 and to stop the movement. You can. As shown by a two-dot chain line in FIG. 10, the movement restricting body 41 may be arranged and fixed in the guide groove between the pair of ridge rails 18.
[0016]
In each of the above embodiments, the movement of each board 7 may be restricted by stopping the protrusion 34 on the top surface 38a of the elastic piece 38.
[0017]
In each of the above embodiments, the case where the movement restricting bodies 33 and 41 are fixed to the lower guide rail 9 has been described. However, the same operation and effect can be obtained even if the movement restricting bodies 33 and 41 are fixed to the upper guide rail 8. .
[0018]
The present invention is applicable not only to the above-described unit-type storage furniture fixed to the floor, but also to other types of furniture such as a case where a board is arranged on the front of storage furniture that can move left and right along the front of the fixed furniture. It goes without saying that you can do it.
[0019]
[Action and Effect of the Invention]
As described in detail above, the board movement restricting device according to the first aspect of the present invention includes a plurality of guide grooves at the front and rear at the upper and lower portions of the front surface of the main body of the storage furniture and the like. The upper guide rail and the lower guide rail are arranged along the frontage direction of the main body, and a board that forms a writing board or a bulletin board is provided between the upper and lower guide rails in a drawing manner . At the corner in the moving direction, a protrusion protruding between the guide grooves of the upper guide rail or the lower guide rail is provided, while the base of the movement restricting body fixed to the end of the upper guide rail or the lower guide rail. A rail insertion groove for closing an end portion of the guide groove is formed, and the movement restricting member has an elastic piece that is disposed along the guide groove so as to protrude from its base and interfere with the protrusion. Those having integrally a recess protrusion is stopped at the root portion of the elastic piece.
[0020]
According to the present invention, the movement of the board can be easily restricted by the elastic piece of the movement restricting body disposed along the guide groove in the guide rail interfering with the projection projecting from the boat. This has the effect of eliminating the need for such troublesome operations as key operation, and of having a very simple configuration.
[0021]
In addition, since the movement restricting body is integrally provided with an elastic piece elastically displaced by the projection and a recess where the projection stops, the projection elastically deforms the elastic piece as the board moves. By doing so, it becomes a resistance to the movement, and the protrusion that has passed over the elastic piece fits into the recess so that the protrusion does not easily come off. With this one-touch operation, the board can be stopped very easily, and the effect of stabilizing the writing operation on the board is achieved.
[0022]
The state, and are not formed integrally with the elastic piece and the recess in the base of the movement restricting member, moreover, the rail insertion grooves for closing the end portion of the guide groove is formed in the base portion, the base portion Since it is fixed to the end of the guide rail, the structure of the movement restricting device is extremely simplified, and the function of preventing the board from falling off from the end of the guide rail and exposing the end of the guide rail is also added. This has the effect of being able to provide a movement restricting device having the same.
