Description

  The present invention provides a measure for storing an electric cord in an appropriate manner in an electric cord storage structure, particularly in an electric device equipped with a reusable battery or a charging device for charging the battery of the self-propelled body. It relates to the structure of the electrical cord storage section taken.

  As this type of electric cord storage portion structure, there is one having a hook row 10 having two hooks 11 and 12 arranged at a distance, as schematically shown in front view in FIG. It was. When an electric cord (not shown) is accommodated in an electric cord accommodating portion including the hook row 10 having this configuration, the electric cord is wound around the two hooks 11 and 12 in a loop shape. Further, when the hook row 10 is lined up and down or left and right on the rising surface, in order to prevent the wound electric cord from falling off the hook row 10, the cord return pieces 13, 14 is often provided.

On the other hand, as for the upright type vacuum cleaner, there has conventionally been known one provided with a pair of upper and lower hooks and a hook part on the upper side of the hooks on the back side of the operation handle (see, for example, Patent Document 1). In addition, a reel-type cord winder that has a framework structure that allows an AC adapter and a cable (corresponding to an electric cord) to be integrally wound and that can increase and decrease the winding diameter of the cord.

  The electric cord storage structure described with reference to FIG. 6 wraps an electric cord around a pair of upper and lower hooks 11 and 12 arranged in a straight line. In such a situation, the cord bundle wound around the hooks 11 and 12 becomes thick and the cord return piece 13 can sufficiently prevent the electric cord from falling off. There is a risk that it will not be possible. In order to solve this problem, it is effective to widen the distance between the pair of hooks 11 and 12 and enlarge the cord return piece 13. However, if the distance between the hooks 11 and 12 is increased, it is necessary to expand the space for storing the electric cord correspondingly, and the electric cord storage portion becomes large. Further, if the cord return piece 13 is made larger, it becomes more difficult to wind the electric cord, so that there is a problem that the troublesomeness of the electric cord storing work increases. Further, in the case of FIG. 6, since there is no function to fit and process the surplus portion of the electric cord wound around the hook row 10, the surplus portion shakes and the electric cord easily falls off the hook row 10. There is also a problem.

  On the other hand, since the thing proposed by patent document 1 has a hook part with a pair of upper and lower hooks, by hooking the surplus part of the electric cord wound around the hook on the hook part. It can also be said that the electric cord has an advantage that it does not easily fall off the hook.

  However, since the hook portion shown in Patent Document 1 is located above the pair of upper and lower hooks, depending on the length of the surplus portion of the electric cord wound around these hooks, the hook portion is hooked. There is a possibility that the hung electric cord hangs down from the hooked portion and swings and collides with other parts to damage the plug at the tip of the electric cord or the vacuum cleaner. Such a fear is likely to occur because there is a variation due to individual differences in the state in which the electric cord is wound around the hook.

  In addition, the reel-type cord winder proposed by Patent Document 2 has a function capable of increasing / decreasing the cord winding diameter, so that the electric power can be adjusted by increasing / decreasing the cord winding diameter. It is also considered that the length of the surplus portion of the cord can be set to an appropriate length, and as a result, the situation where the surplus portion hangs down and swings can be avoided. However, this is a combination of four plates assembled in an X-shape for winding an electric cord and four pin components, so the components of the cord winder itself are In addition, it can be said that it tends to be large. Therefore, if it is used to store an electric cord such as a charging device, the entire charging device is increased in size by the electric cord storage portion, and the assembly workability is also reduced, so that mass productivity is impaired. It can be said that.

  The present invention has been made in view of the above problems and circumstances, and by taking measures that can increase the length of one turn of the electric cord with respect to the hook row without expanding the space for storing the electric cord, Not only can a long electric cord be wound around the hook row in a state that is not so bulky, it is possible not only to avoid an increase in the size of the cord return piece, but also due to individual differences in the state of the electric cord wrapped around the hook row. In view of the above, an object of the present invention is to provide an electric cord storage portion structure having a function capable of accommodating a surplus portion of an electric cord wound around a hook row and processing it well.

  An electric cord storage unit structure according to the present invention includes a hook row around which an electric cord drawn out from a functional unit is wound, and a cord holding member for holding an excess portion of the electric cord wound around the hook row. It has. The hook row has three or more hooks arranged at intervals in at least three places that are not arranged in a straight line, and the cord holding member has the same separation interval from each hook. It has a groove part which is arranged in the place and the surplus part of the above-mentioned electric cord is inserted.

  With this configuration, the hook row has three or more hooks arranged at intervals in at least three places where the hook rows are not arranged in a straight line, so that the space for storing the electric cord is not expanded. In addition, the length of the electric cord wound around the hook row can be easily made longer than that described with reference to FIG. Therefore, the number of times the electric cord is wound around the hook row is reduced, and the cord bundle wound around the hook row is suppressed from becoming bulky and thick, and the electric cord is less likely to fall off the hook row. In addition to this, since the cord holding member is disposed at a position where the distance from each hook is the same, even if there are individual differences in the winding state of the electric cord around the hook row, at least three hooks By appropriately selecting one of the above, it becomes possible to make the length of the surplus portion of the electric cord approximately the same length, and for that purpose, the surplus portion is sandwiched in the groove portion of the cord holding member and the surplus portion droops. It becomes possible to process so that it does not fall.

  In the present invention, the hook row is integrally formed of resin on a bottom plate made of resin in a recessed portion that forms an electric code storage space, and the cord holding member is formed on the top of a protrusion integrally formed on the bottom plate. It is desirable to have According to this, since it is not necessary to use an extra separate part as a hook or a cord holding member constituting the hook row, the number of necessary parts for constituting the electric cord storage portion structure is not increased, and assembly workability is increased. There will be no loss of mass productivity.

  In the present invention, it is possible to adopt a configuration in which the above hook example is composed of three hooks individually arranged at the tops of three isosceles triangles. There is an advantage that the workability of winding the cord can be kept good.

  In the present invention, it is desirable that each hook included in the hook row is provided with a cord return piece that locks the electric cord wound around the hook row and prevents the cord from falling off. For example, the electric cord wound around the hook row by the cord return piece is prevented from falling off. Moreover, even if a cord return piece is added, as described above, the length of one turn of the electric cord with respect to the hook row becomes longer and the electric cord becomes less bulky. Therefore, there is a need to increase the size of the cord return piece. Not necessarily gone. Therefore, it is useful for reducing the troublesome work of storing the electric cord.

  An electric cord storage unit structure according to the present invention includes a hook row around which an electric cord drawn out from a functional unit is wound, and a cord holding member for holding an excess portion of the electric cord wound around the hook row. And the functional unit has a function of charging a battery mounted on the self-propelled body and is accommodated in an electric box, and the charging unit provided in the self-propelled body is provided on the front side of the electric box. A receiving-side terminal portion is installed, and a recessed portion that forms an electric cord storage space is provided on the back side of the electric box, and the hook example and the cord holding member are attached to the bottom plate made of resin of the recessed portion. Are integrally formed of resin, and the electric cord is drawn out from the functional part through a drawing outlet formed in the bottom plate, and the hook row is individually arranged on three tops of an isosceles triangle. Each hook is provided with a cord return piece for locking the electric cord wound around the hook row to prevent the hook from falling off, and the cord holding member is connected to each hook from the hook. The present invention is further embodied by adopting a configuration in which a protrusion is provided at a top portion that is provided at a location where the separation interval is the same and in which an excess portion of the electric cord is sandwiched.

  In particular, in the electrical cord storage structure according to each of the inventions described above, a configuration is adopted in which the protrusions forming the cord holding member are separated from the bottom plate and are rotatably attached to the bottom plate. It is also possible to do. By adopting this configuration, the projections forming the cord holding member can be rotated in accordance with the pulling direction of the excess portion of the electric cord wound around the hook row, so that the electric cord is inserted into the groove portion of the cord holding member. There is an advantage that the surplus portion can be easily inserted without bending. Due to this advantage, it is possible to easily process the surplus portion, and it is possible to eliminate the possibility that the surplus portion may be bent excessively and cause damage such as disconnection.

  As described above, the structure of the electric cord storage unit according to the present invention increases the number of hooks constituting the hook row to increase the length of the electric cord when compared with the structure described with reference to FIG. It is a long one, and by simply selecting one hook that pulls out the surplus portion of the electric cord wound around the hook row, the surplus portion is sandwiched in the groove portion of the cord holding member so as not to hang down for a long time. Is made possible. For this reason, it is possible to wrap a long electric cord in a state that is not so bulky even if it is a long electric cord without expanding the space for storing the electric cord. This is advantageous in that it is difficult to cause a situation where the item falls off the hook row. Such an effect is exhibited even when there is a variation in the winding state of the electric cord around the hook row due to individual differences, so that the electric cord can be stored in an orderly manner without troublesome work for the user. There is convenience that you will be able to.

  FIG. 1 is a schematic perspective view of a charging device A provided with an electric cord storage portion structure B according to an embodiment of the present invention, FIG. 2 is a schematic perspective view of the electric cord storage portion structure B, and FIG. FIG. 4 is a side view for explaining the hook 31 and the electric cord C wound around the hook 31.

  FIG. 1 illustrates a charging device A used for charging a battery mounted on a self-propelled body (not shown) having a function of performing a required task related to security and cleaning. In this charging device A, an electric box 110 is provided on a seat plate portion 100 that can be stably placed on a floor or the like, and the electric box 110 has a functional unit (such as a circuit board required for charging). (Not shown) is accommodated. And the electric power feeding side terminal part 112 used for charge protrudes forward, and this electric power feeding side terminal part 112 serves as an other party terminal part of the electric power receiving side terminal part (not shown) with which the self-propelled body which is not illustrated is equipped. Have a role. Furthermore, the electric box 110 is provided with a light emitting unit 113 for performing optical communication with the self-propelled body.

  As shown in FIG. 3 or FIG. 4, a recessed portion S that forms an electric cord storage space is provided on the back side of the electric box 110, and a hook row is formed on the bottom plate 20 (see FIG. 4) made of resin of the recessed portion S. 30 and the cord holding member 40 are integrally formed of resin. Thus, if the hook row 30 and the cord holding member 40 are formed integrally with the bottom plate 20 of the recessed portion S, the hook row 30 and the cord holding member 40 do not become separate parts, so the number of parts does not increase. Therefore, there is an advantage that the mass productivity of the charging device A is not hindered.

  In addition, the electric cord C is drawn out from the functional portion through the outlet 21 formed at the corner of the bottom plate 20. Then, the electric cord C drawn from the functional unit is wound around the hook row 30, and the surplus portion C1 of the electric cord C wound around the hook row 30 is held by the cord holding member 40. Yes. A plug P that can be connected to a commercial power outlet is connected to the tip of the electric cord C.

  In this embodiment, the hook row 30 includes three hooks 30 that are not arranged in a straight line, specifically, the height direction of the vertically rising bottom plate 20, and one hook 31 is located at the upper part and two hooks 30 at the lower part. The hooks 32 and 33 are located, and the spacing distance between the upper one hook 31 and the lower two hooks 32 and 33 is the same. In other words, the upper one hook 31 and the lower two hooks 32 and 33 are individually arranged at three apexes (corners) of an isosceles triangle. Therefore, if the separation distance between the upper one hook 31 and the lower two hooks 32 and 33 is the same as the separation distance between the pair of upper and lower hooks 11 and 12 shown in FIG. The winding length of the electric cord C wound around the hook row 30 composed of the two hooks 31, 32, 33 as shown in FIG. 3 is equal to the hook row 10 composed of the pair of upper and lower hooks 11, 12 shown in FIG. It becomes longer than the length of the wound electric cord. Therefore, when the case where the electric cord C is wound around the hook row 30 in FIG. 2 or FIG. 3 is compared with the case where the electric cord C is wound around the hook row 10 in FIG. May be less than the latter, but not more. Therefore, when one hook 31 is viewed as shown in FIG. 4, the bundle of electric cords C wound around the hook 31 is not so thick and bulky, and as a result, the electric cord C is not connected to the hook row 30. It becomes difficult to drop off. Further, when the cord return pieces 34, 35, 36 provided on the individual hooks 31, 32, 33 are prevented from dropping off from the hook row 30, the cord return pieces 34, 35, 36 are provided. It is possible to easily reduce the electric cord C winding workability.

  The cord holding member 40 is disposed at a location where the spacing distance from each of the hooks 31, 32, 33 is the same, that is, at the center of the above-mentioned isosceles triangle. Further, the cord holding member 40 is formed by a protrusion protruding from the bottom plate 20, and a groove portion 41 which is equal to or slightly narrower than the thickness of the electric cord C is formed at the top portion thereof. The groove 41 is used to sandwich and hold the surplus portion C1 of the electric cord C wound around the hook row 30 as shown in FIG.

  As described above, the hook row 30 is composed of the three hooks 31, 32, 33 individually arranged on the three apexes of the isosceles triangle, and the cord holding member 40 is connected to each hook 31, 32, 33. If the separation distance is the same, the surplus portion C1 of the electric cord C wound around the hook row 30 can be reduced even if the winding state of the electric cord C around the hook row 30 varies due to individual differences. Only by appropriately selecting one hook to be pulled out (the hook 31 in the illustrated example), the excess portion C1 can be sandwiched and held in the groove portion 41 of the cord holding member 40 so as not to hang down for a long time.

  In the embodiment described above, the case where the cord holding member 40 is integrally formed with the bottom plate 20 with the resin has been described. However, in this respect, the protrusion forming the cord holding member 40 is separated from the bottom plate 20 and It may be rotatably attached to the bottom plate 20. Such an example is shown in FIG.

  That is, FIG. 5A is a partial cross-sectional view of the attachment location of the cord holding member 40, and FIG. 5B is an operation explanatory view of the cord holding member 40. As shown in FIG. 3A, the cord holding member 40 is provided with a support shaft 41, and the support shaft 41 is rotatably held in the shaft hole 22 formed in the bottom plate 20. As shown in the figure, when the cord holding member 40 is configured to be rotatable, the protrusion that forms the cord holding member 40 according to the drawing direction of the surplus portion C1 of the electric cord C wound around the hook row 30 (B) in the same figure can be rotated in an arbitrary direction as indicated by an arrow R, so that the groove portion of the cord holding member 40 can be obtained by rotating the protrusion to match the longitudinal direction of the groove portion 41 with the pulling direction of the surplus portion C1. It is possible to easily pinch the surplus portion C1 of the electric cord C to 41 without bending it. Therefore, the user can easily process the surplus portion C1, and there is no possibility that the surplus portion C1 bends forcibly and causes damage such as disconnection.

  In the embodiment described above, the example in which the hook row 30 is configured by the three hooks 31, 32, 33 has been described. However, the number of hooks constituting the hook row 30 is not limited to three, and is four. May be larger. When the number of hooks is three or more, the hooks may be positioned at the top of an irregular polygon that does not have a regular polygon or a recessed portion.
