Description

  The present invention relates to a lever device structure, and more particularly to a novel device for aligning a housing with a link mechanism in a predetermined manner by mounting a housing having a plurality of gear box portions to a housing through fitting portions. Related to various improvements.

  In the case of a unit-type housing using a plurality of gearbox portions using this type of rotating lever, which has been used in the past, no patent application has been filed for in-house production, so no patent document is disclosed. However, the housing is mounted on the housing by screwing.

Since the mounting of the housing to the housing having the conventional lever is configured as described above, the following problems exist.
In other words, since the housing is attached to the housing via a plurality of screws, it is difficult to position the shaft with respect to a predetermined position of the housing, and the positional relationship with the link mechanism of the lever attached to the housing side is designed. It was difficult to pass.

  The lever device structure according to the present invention includes a plurality of gear box portions provided along the longitudinal direction of the housing, individual drive shafts rotatably provided in the gear box portions, and an upper portion of the housing. An upper drive shaft that is provided and driven by a motor, a slip clutch that operates in conjunction with the upper drive shaft and drives the individual drive shaft, a rotation lever that is provided at the lower portion of each gear box portion, and each rotation lever A lever gear that is coupled to the slip clutch, a pair of concave or convex first fitting portions formed on both outer surfaces of the housing, a housing that houses the housing, and both sides of the housing A pair of convex or concave second fitting portions provided on the portion, and by fitting and connecting each of the first fitting portions and each of the second fitting portions, The casing is positioned, and the link mechanism of the pivot lever pivotally supported on the housing is connected to the gear of the gear box portion of the casing. .

Since the lever device structure according to the present invention is configured as described above, the following effects can be obtained.
That is, a plurality of gearbox portions provided along the longitudinal direction of the housing, individual drive shafts that are rotatably provided in the gearbox portions, and a motor provided at the top of the housing. An upper drive shaft; a slip clutch that interlocks with the upper drive shaft and drives the individual drive shaft; a rotation lever provided at a lower portion of each gear box portion; and a slip clutch provided at each rotation lever. Lever gears interlocking with each other, a pair of concave or convex first fitting portions formed on both outer surfaces of the housing, a housing for housing the housing, and convex or convex portions provided on both side portions of the housing. A pair of concave second fitting portions, and the positioning of the housing in the housing by fitting and connecting the first fitting portions and the second fitting portions. Can be performed, it is possible to match the positional relationship between the linkage gear box portion and the lever housing easily and accurately.
In addition, the link mechanism of the pivot lever pivotally supported by the housing is connected to the gear of the gear box portion of the housing, so that the gear box portion can be accurately operated by the lever. it can.

  An object of the present invention is to provide a lever device structure in which a housing having a plurality of gear box portions is mounted on a housing through a fitting portion so that the housing is aligned with a link mechanism in a predetermined manner. To do.

A preferred embodiment of a lever device structure according to the present invention will be described below with reference to the drawings.
In FIG. 1, a reference numeral 1 denotes a housing having a box shape as a whole, and four levers 4 are provided between the pair of opposite side portions 2 and 3 of the housing 1 so as to form a first shaft support portion 5. Is provided so as to be reciprocally rotatable along the direction of the arrow A.

  A housing 10 as an internal unit indicated by a dotted line in FIG. 3 is disposed at a position below the first shaft support portion 5 provided on each of the side portions 2 and 3. The gear box portion 11 is disposed along the longitudinal direction of the housing 10.

A first rod 14 is connected to the lower end portion 12 of the lever 4 via a second shaft support portion 13, and a second rod 16 is connected to the first rod 14 via a third shaft support portion 15. The two rods 16 are connected to the gear 17 of the gear box portion 11.
Accordingly, each lever 4 described above is connected to each gear 17 of each gear box portion 11 as shown in FIG. The lever 4, the first rod 14, and the second rod 16 constitute a link mechanism 20 for connecting the lever 4 to the gear 17.

  Each gear box portion 11 provided in the housing 10 is configured as shown in FIGS. 1, 2, 4, and 5, and an individual drive shaft 21 rotates in each gear box portion 11. It is provided freely.

  At the uppermost position of the housing 10, a common upper drive shaft 23 that is rotationally driven by a motor 22 is disposed in a state of crossing each gear box portion 11 in the axial direction. The rotation is transmitted to the individual drive shaft 21 via the slip clutch 24.

  At the lower position of each gear box portion 11, a lever gear 26, to which each of the four rotation levers 25 is connected, is rotatably provided via a shaft 27. It is configured to be able to rotate in conjunction.

  A pair of first fitting portions 42, 43 are provided on the outer side surfaces 40, 41 on both sides of the housing 10, and each of the first fitting portions 42, 43 is shown in FIG. (Only shown), the overall shape is formed into a disk shape. In the case of the configuration of FIG. 1, it is configured to have a concave shape in cross section.

Although each said 1st fitting part 42 and 43 was made into the said concave disk shape in FIG. 1, it can also be set as a cross-sectional convex shape not only in the said concave shape.
The two side portions 2 and 3 of the housing 1 in which the housing 10 is provided are formed so as to be able to be fitted to the first fitting portions 42 and 43, and have a disk shape having a convex or concave cross section. A pair of second fitting portions 44 and 45 having the same shape as the first fitting portions 42 and 43 are provided.

  Accordingly, the first and second fitting portions 42, 43, 44, 45 are configured in a male-female fitting type, and the first fitting portions 42, 43 of the housing 1 have a concave shape. Each of the ten second fitting portions 44 and 45 is formed in a convex shape, and can be a combination of the opposite shapes, either of which can be applied.

Since each of the first and second fitting portions 42, 43, 44, 45 is formed in a disk shape as described above, the shaft center positioning according to a predetermined design is easy when fitted to each other. The housing 10 can be mounted at a predetermined position with respect to the housing 1.
Therefore, the positional relationship between the link mechanism 20 of the lever 4 and the gear 17 of the gear box portion 11 can be connected at the designed position.

It is a permeation | transmission perspective view which shows the lever apparatus structure by this invention. It is an expansion perspective view which shows the housing | casing of FIG. It is a block diagram which simplifies and shows the structure of FIG. FIG. 3 is an enlarged exploded perspective view of FIG. 2. FIG. 5 is a front view of FIG. 4.
