Driving device of moving object {DRIVING DEVICE FOR MOVING BODY}

The present invention relates to a driving device for moving a mobile body through engagement of a rack and a gear with respect to a base, and in particular, the mobile body has an interlocking means interposed between the gear and the moving body in the process of rotating the gear in one direction. It relates to a driving device of a mobile body of the configuration that accumulates the force of the.

The drive device which becomes the object of this invention is a form which moves a movable body between the 1st position and the 2nd position of a base side, Patent Documents 1 and 2 for the purpose of making a movement characteristic and ease of use favorable. As disclosed in the above, the movable body is moved through the engagement of the rack and the gear, and has a gripping means interposed between the gear, and the gripping force is accumulated in the gripping means in the process of rotating the gear in one direction, Is rotated in the other direction by the accumulated gripping force to move the moving body to any one of the first position and the second position.

In this structure, since the gear is connected to the holding means, for example, if an error occurs in arranging or assembling the gear with respect to the moving object, the degree of holding force accumulated in the holding means varies depending on the product. It is a factor that causes the movement speed of the moving body to be operated by the resistive pressing force (ie, during the accumulation of the force) and the force of the force.

Here, Patent Literature 1 discloses a structure having a force changing means for changing the holding force of the holding means by the operator's operation, and by means of the holding force changing means, the dispersion of the holding force can be adjusted for each product. The holding means has an end side fixing portion of the holding member and an operation portion for manipulating the position change of the holding portion. The holding force changing means has an allowable portion allowing movement of the holding portion and a plurality of locking portions disposed within the moving range of the holding portion to allow the holding portion to walk, and the holding force of the holding portion corresponds to the position of the holding portion to which the holding portion is caught. To change the structure.

In addition, Patent Document 2 has a first stopper portion formed on an outer circumference of a gear (pinion) and a locking position and the whole of which is attached to a moving body (base body made of a holder body or the like) and at least part of which protrudes into a moving region of the first stopper portion. It has a 2nd stopper part which moves between release positions which recede out of a movement area. In this structure, the second stopper portion is disposed at a locking position when the movable body is assembled to the base and is engaged with the first stopper portion, and is disposed at a release position when the movable body moves between the first position and the second position. It is to be able to assemble the movable body to the base with the initial force to the means.

Patent Document 1: Japanese Patent Application Laid-Open No. 2007-145250 Patent Document 2: Japanese Patent Laid-Open No. 2008-62694

In the holding force changing structure of Patent Document 1, there is a limitation in the arrangement portion of the holding means in design, and in many cases, it is impossible to secure an arrangement that can be operated by holding the operation portion in order to change the position after productization. Moreover, it is not only very cumbersome for the operator (i.e., non-expert) to change the locking position of the fixing part by manual operation, but also cannot be set in an optimal state.

Moreover, in the stopper structure of the said patent document 2, since the 2nd stopper part is attached to a movable body, it is a structure which moves between the latching position which a part protrudes into the moving area of the 1st stopper part, and the release position which the whole retracts out of the moving area, The configuration is complicated, and positional accuracy with respect to the first stopper portion on the gear side is also required. In this structure, since the second stopper portion is formed on the rotating member (bottom support member of FIG. 2 or the connecting member of FIG. 6), the movable body is inserted into the inner space of the base so that both stopper portions are engaged with each other. It is difficult to operate, and the engagement force is released by the insertion force or the engagement position of the gear and the tooth part of the rack is shifted.

The present invention has been made to solve the above problems. The object of the present invention is to support the gears on the movable body with the initial holding force on the holding means and to assemble the base in this state so as to fully exhibit the operating characteristics due to the holding force, for example. By means of the positioning means of the invention, the engagement position of the gear and the tooth of the rack is maintained as designed, thereby making it possible to reliably and optimally obtain operating characteristics. Another object is to simply realize the positioning means without increasing the number of parts.

The present invention for achieving the above object is based on the embodiment of Figs. 1 to 6, the movable body 2 is engaged with the rack 14 and the gear 5 with respect to the base 1, the base through It is assembled so as to be movable between a 1st position and a 2nd position on the side (1), and also has the holding means 6 interposed between the said gear 5, and the said gear 5 rotates in one direction. In the process, a fingering force is accumulated in the fingering means 6, and the gear 5 is rotated in the other direction by the accumulated fingering force, thereby moving the movable body 2 to any one of the first position and the second position. And the teeth of the gear 5 and the rack 14 by movement of the movable body 2 along the base 1 when assembling the movable body 2 to the base 1. Positioning means (engaging recess 54 and convex portion 19) for engaging at a predetermined position Or in the case of having the toothed shape 14a and the engaging part 54a},
The movable body 2 enters and leaves the inner space of the base 1, and the positioning means is formed inside the partition wall 10 partitioning the inner space of the base 1. It is characterized in that it comprises a convex portion 19, the protrusion amount is increased toward the inner side, and the engaging concave portion 54 formed on the gear (5) can engage with the convex portion (19).

Here, the gear 5 has passed through the convex portion 19 with the elastic displacement on the side of the partition wall 10 during the initial process of inserting the movable body 2 into the inner space of the base 1. At the same time, the engaging recess 54 and the convex portion 19 are engaged with the rack 14 at the same time, and the horizontal piece which partitions the engaging recess 54 in this engaged state. It is the structure which can be engaged with the rack 14 by hanging 55b on the cross section of the said convex part 19. As shown in FIG.

The positioning means is engaged with the engaging portion 54a which forms a heterogeneous shape different from the shape of the other teeth and engages with each other in the toothed portion of the gear 5 and the rack 14 and is able to engage with each other. It is the structure which has the part 14a, respectively.

The protruding portion 59 formed in the gear 5 is fitted into the fitting hole 25a formed in the movable body 2 so that the gear 5 accumulates a predetermined finger force in the holding means 6. A structure including a restricting means (fitting hole 25a and a protruding portion 59) which maintains an initial state and prevents rotation in a direction of weakening the holding force in the initial state of the holding means 6. to be.

In the invention of claim 1, the teeth of the gear and the rack are always engaged at a predetermined position by the positioning means by the normal moving operation along the base of the moving body. Therefore, as the driving device of the movable body, the gear is supported by the movable body with the initial holding force applied to the holding means, and even in this state, even if the structure is assembled to the base, the dispersion of the holding force for each product is eliminated so that the rack and the gear are not supported. Operating characteristics using the engagement mechanism and the grip force can be reliably and optimally provided.

In addition, as shown in Fig. 4, the positioning means is formed in the inside of the partition wall partitioning the inner space of the base, and the engaging concave portion formed in the convex portion and the gear which increases the protrusion amount toward the inner space of the inner space. Since it is made, for example, compared with the structure of patent document 2, it can carry out easily, without increasing the number of components, and malfunction also hardly arises.

In the initial process of inserting the moving body into the inner space of the base, the gear engages with the rack and engages the engaging recess and the convex portion at the same time as the gear passes through the convex portion with the elastic displacement of the partition wall on the base side. Moreover, in this engagement state, the horizontal piece which partitions the engagement recessed part is hanged on the end surface of a convex part, and the engagement state with a rack is maintained. Therefore, as the driving device of the movable body, when the movable body is inserted and operated in the internal space of the base while supporting the gear, the gear and the teeth of the rack are accompanied by the assembly sound that 'clicks' upon restoration after the elastic displacement of the base side partition wall. Since it engages in a predetermined position, assembly operability can be improved.

And since the positioning means has the engagement part and the engaged part which can form a heterogeneous shape different from the shape of other teeth, and can engage with each other, respectively, for example in the structure of patent document 2, On the contrary, it can be realized simply without increasing the number of parts. Further, as a driving device of the moving object, there is an advantage in that the engagement state of the engagement portion and the engaged portion can be visually confirmed with respect to whether or not the positioning is normal.

Further, as a restricting means for preventing rotation in the direction of weakening the force of the finger in the initial state of the finger which accumulated the predetermined force, it has a simple configuration consisting of a fitting hole on the side of the moving body and a protrusion on the side of the gear. Compared with the structure of Patent Literature 2, it is simplified and easy to implement, and malfunctions are less likely to occur.

(2) (b) and (c) in FIG. 5 and FIG. 6 show the intermediate state and the completed state in which the holder main body 2 is assembled to the case 1 as mentioned above. That is, in this structure, the gear 5 is the convex part among the partition walls partitioning the inner space of the case 1 in the initial process when the holder body 2 is inserted into the inner space of the case 1. It passes through the convex part 19 with elastic displacement of the partition wall (upper wall 10) which forms 19.

In detail, FIGS. 5 (b) and 6 (b) show that the escape portion 53 of the gear 5 abuts the convex portion 19 as the holder body 2 is inserted into the case 1. It is a state which is further inserted in this contact state. In this structure, since the convex portion 19 is an inclined surface 19a in which the amount of protrusion gradually increases toward the front side as shown in Fig. 4 (c), the convex portion 19 forms the convex portion 19. Along with the elastic displacement of the partition wall (upper wall 10), it climbs on the skin 53 of the gear 5 relatively smoothly. Further, the corresponding side surface of the convex portion 19 is guided to be positioned along the vertical piece 55a of the rib 55 as shown in Fig. 6 (b) and pressed in the direction of the arrow in Fig. 6 (b). Then, when the escape part 53 of the gear 5 passes through the convex part 19, the convex part 19 engages with the engagement recess 54, and the tooth part of the gear 5 The engaging portion 54a, which has once formed the teeth adjacent to the engaging recess 54 in the 50 at a low level, engages with the heterogeneous teeth 14a of the rack 14, that is, the engaged portion.

(3) The engagement between the above-mentioned engagements is obtained when the partition wall portion (in this embodiment, the rear left and right middle portions of the upper wall 10 on which the convex portion 19 is formed) is restored to its original state in the elastic displacement state. It is accompanied by a click sound. Therefore, the operator hears the above-mentioned assembling sound that the holder main body 2 is securely assembled to the case 1, and further, as shown in Fig. 6 (c), the engaging portion 54a and the deformed tooth 14a are shown. This can be confirmed by visually checking the engagement of

In this structure, the gear 5 is engaged with the rack 14, and the convex portion 19 is engaged with the engagement recess 54, and the escape portion 53 and engagement with the engagement state. The horizontal piece 55b of the rib 55 which partitions the recessed part 54 hangs on the cross section of the convex part 19. As shown in FIG. As a result, in this structure, the engagement state between the gear 5 and the rack 14 is maintained, thereby reliably eliminating the fear that the gear 5 is unnecessarily removed from the rack 14.

(4) The above drive unit 9 is in a storage position in which the holder main body 2 is pushed into the case 1 as shown in Fig. 1 (a). When the gear 5 is rotated in the clockwise direction when the gear 5 is engaged with the rack 14 when it is switched from the use position to the stowed position, a force in proportion to the amount of rotation of the gear 5 is accumulated. The holder body 2 is a storage position stored in the case 1 through latch means (that is, engagement of the pin portion 7a of the pivot piece 7 and the heart-shaped cam groove 16) against the gripping force. Is kept on. In this storing state, the above-mentioned slide contact 44 is fitted into the upper horizontal groove 58, and the above-mentioned contact portion 45 is formed on the inner surface of the upper wall 10 of the front portion 20b. Since it is in contact with, the swing that is likely to occur between the members is reliably prevented.

On the other hand, when switching the holder main body 2 to a use position, the decorative plate 27 of the holder main body 2 is pushed. In this manner, the holder main body 2 is released from the engagement of the pin portion 7a and the cam groove 16 and the gear 5 is engaged with the rack 14 by the holding force accumulated in the holding means 6. By rotating counterclockwise, it is switched to the use position of Fig. 1 (b). In this switching process, the gear 5 is rotated at a low speed by the rotary damper 8 so that rapid movement of the holder main body 2 is alleviated. Further, the bottom support member 3 is supported by the slide contact 44 of the arm 4 and the cam body 56 of the gear 5 by the cam action so as to intersect the holder main body 2 up and down in an unsupported position. Will be switched to position. In this use state, since the slide contact member 44 fits into the inclined groove 57 and is in pressure contact with the left inclined piece 51b from the lower side of the inclined groove 57, fluctuations easily occur between members. This is reliably prevented. In this state, when containers not shown are inserted from the upper side to the lower side in the container insertion hole 21 of the holder main body 2, the bottom of the container is placed on the bottom plate portion 31 of the bottom support member 3 to be supported. At the same time, the periphery of the container is constrained between the side support part 32 and the sub holder 28 to be stably maintained.

In addition, the above embodiment does not restrict this invention at all. The present invention can be deployed in various devices with reference to the above-described embodiments. For example, the base and the holder main body are developed as a desk, a small box, a drawer, various device main bodies, and a cover and a door.
