Description

  The present invention relates to a pivot attachment mechanism that pivotally attaches one member and another member to be rotatable around a predetermined axis.

  Conventionally, as such a pivoting mechanism, for example, by supporting a common shaft on a shaft support member such as a bracket provided on the one member and a shaft support member such as a bracket provided on the other member, There is one in which one member and another member are configured to be rotatable. Then, in order to prevent one of the shaft and the shaft support member from falling off (detaching) from the other in the shaft support posture, for example, a concave groove is formed at one end portion of the shaft, and an E-ring or C There are many modes (first mode) in which a retaining member such as a ring is fitted, modes in which one end of the shaft is crimped (second mode), or modes in which a nut is fastened to one end of the shaft (third mode). It has been adopted. Note that the above-described conventional techniques are appropriately implemented in the field, and there is nothing disclosed as patent documents.

  However, in the case of the first aspect, a concave groove must be machined in the shaft, and a dedicated retaining member such as an E-ring is required, resulting in complicated parts machining and an increase in the number of parts. is there. Further, in the case of the second mode, since the process of caulking the tip of the shaft is necessary, there is also a problem that parts processing is troublesome and the number of man-hours is increased. Since the retaining member is required, the number of parts increases and the installation work becomes complicated. As described above, each of the above-described aspects that have been conventionally employed impairs the ease of machining of the shaft itself, resulting in an increase in the number of parts and a complicated mounting operation.

  The present invention has been made paying attention to such problems, and the main purpose thereof is to perform unnecessary processing on the shaft and each shaft support member, and without using a dedicated retaining member. An object of the present invention is to provide a pivoting mechanism that can effectively prevent the pivoting posture of the pivotal support member from being released.

  That is, the pivot attachment mechanism of the present invention is a pivot attachment mechanism that pivotally attaches one member and another member so as to be rotatable about a predetermined axis, and is provided on the shaft and the one member. A first support member that supports the shaft, a second support member that is provided on the other member and supports the shaft, and the shaft is supported by the first support member and the second support member. A shaft support posture release preventing portion for preventing the shaft support posture from being released due to relative movement between the shaft and each of the shaft support members along the axial direction in the supported shaft support posture. The support posture release preventing unit is provided in association with the one member or the other member and is a part of a member component constituting the one member or the other member.

  Here, the “shaft” is a concept that includes the shaft itself that is pivotally supported by the first pivotal support member and the second pivotal support member, and a member that is provided in association with the shaft and contributes to maintaining the pivotal support posture of the shaft. is there. In addition, the “supporting member that supports the shaft” means a supporting member that supports the shaft in a state where it is fixed so as not to move relative to the shaft, or is rotatable / slidable relative to the shaft. Means a shaft support member that supports the shaft in a stable state, and at least one of the first shaft support member and the second shaft support member is mounted so as to be rotatable and slidable relative to the shaft As long as the shaft is supported by

  If this is the case, it is possible to prevent the pivot support posture from being released using a part of the member constituent elements constituting one member or the other member, and a part of the shaft as in the past. It is not necessary to provide a concave groove for attaching the E-ring or to caulk one end of the shaft, so that the workability of the shaft and the shaft support member is not impaired. Moreover, since it is not necessary to attach a dedicated retaining member such as an E-ring or a nut to the shaft, the work process can be simplified and the number of parts can be effectively reduced.

  In addition, if the pivot support posture release preventing portion regulates relative movement between the shaft and each pivot support member along the axial center direction in the pivot support posture, the pivot support posture is ensured. Can be secured.

  Further, the shaft is capable of being pulled out only in one direction with respect to the respective shaft support members in the shaft support posture, and the shaft support posture release preventing portion abuts on the shaft from the one direction side, As long as the movement of the shaft in the one direction is restricted, it is possible to appropriately prevent the shaft from being removed and to reliably prevent the relative movement of the shaft relative to the shaft support member. Can be secured.

  Each of the first pivot support member and the second pivot support member has a pair of opposed pieces, and each opposed piece is in contact with or in close proximity to each other. If the different shafts are pivotally supported, and the relative movement of each shaft and each shaft support member along the axial direction is restricted by a single pivot support posture release preventing portion, a good pivoting state is achieved. To achieve this, even if a pair of opposing pieces are provided for each axial support member and the axis is axially supported by each of these opposing pieces, the axial support attitude is released with a single axial support attitude release prevention unit. Can be prevented accurately, an increase in the number of unnecessary parts can be avoided, and the cost can be reduced. Here, the shafts pivotally supported by the opposing pieces may be the same type of shaft or different types of shafts.

  In particular, each of the different shafts can be pulled out only in the direction in which the different shafts come together using a gap formed between the shafts in the shaft support posture, and the shaft support posture release preventing portion is provided in each shaft. If it is fitted in the gap formed between them and abuts each of these shafts to restrict movement of each of the shafts in the direction where they come together, each shaft is reliably prevented from being pulled out, A good pivoting posture can be realized.

  A plurality of the first shaft support members are provided on the one member, and a plurality of the second support members are provided on the other member in correspondence with the first shaft support member, and the plurality of first shafts are provided. If the supporting member and the second supporting member are pivotally mounted on the same axis using their respective shafts, and a plurality of the supporting posture release preventing portions are provided corresponding to the supporting members, one member is provided. When other members and other members are pivotally attached at a plurality of locations, it is possible to ensure a favorable pivot support posture at each of these pivotal attachment portions. In this case, if the plurality of pivot support posture release prevention portions are provided integrally, the storage support, handling and mounting workability are superior compared to the case where the pivot support posture release prevention portions are individually provided. It becomes.

  As a specific embodiment, the one member is an advancing / retreating member that is guided by a rail portion provided in a housing and can move forward and backward, and the other member is pivotally attached to the advancing / retreating member and An opening / closing body that opens and closes a storage space of the housing, and the opening / closing body includes a frame, a panel member that can be attached to the frame, and a fixing member that fixes the panel member to the frame. A shaft support posture release preventing portion is a part of the fixing member.

  Moreover, it contributes to the improvement of the functionality and practicality of the said fixture by setting it as the fixture provided with the pivot attachment mechanism with the above effects.

  As described above, according to the present invention, it is possible to prevent the pivot support posture from being released by using a part of the member constituent elements constituting one member or the other member, and the shaft and the pivot support member. Therefore, it is not necessary to attach a dedicated retaining member such as an E-ring or a nut to the shaft, so that the work can be simplified and the number of parts can be effectively reduced.
