Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bottom member of a rod in a box measure or the like.

(Prior Art) Conventionally, the bottom member of this type of rod has a structure in which the bottom member is fitted mainly to the end of the rod, and then the both are fixed by an adhesive and a rivet. Was adopted.

(Problems to be solved by the invention) However, in the conventional structure described above,
Since a special adhesive and rivets are used, the workability is inevitably deteriorated and the cost of the product itself is increased.

Therefore, in view of the above-mentioned conventional drawbacks, the present invention can easily assemble the bottom member to the end portion of the rod without using a special material, which improves workability and further reduces cost. It is an object of the present invention to provide a bottom member for a rod body in a box scale or the like that can be made inexpensive.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention is a bottomed bottom member that is fitted to the end of a rod such as a box scale, and has a cross-sectional shape of the rod. In addition to forming an almost contoured outer shape,
At least both side members are formed to be elastically deformable, and an engaging projection is formed on a part of the both side members, while an engaging hole is formed through a side surface of the rod body, and a bottom member is formed at an end portion of the rod body. It is the gist that the engaging projections of the both side members are fitted to each other by applying an elastic force to the engaging hole of the rod when the two are fitted together.

(Operation) According to the above configuration, when the bottom member is fitted to the end portion of the rod, the engaging projections of both side members of the bottom member are fitted to the engaging holes of the rod by elastic force. Let's make the two firm.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.
As shown in FIG. 3, a rod 1 used in a box measure is formed in a predetermined cross-sectional shape (showing a flat and substantially rectangular shape in the figure), an end surface of which is opened, and a rod is also provided. A small-diameter engagement hole 2 is provided in the vicinity of the end portions of both side surfaces of the No. 1. Then, the bottom member 3 is fitted and fixed to the opening end face.

The bottom member 3 is integrally molded from a synthetic resin, for example, and is integrally formed in a bottomed outer shape that substantially matches the cross-sectional shape of the rod 1. Two slits 5 and 5 are formed almost in the center so that they are elastically deformable. Engaging projections 6 and 6 that can be engaged with and disengaged from the engaging holes 2 of the rod 1 are integrally formed at substantially end portions of the elastically deformable pieces 4a and 4a of the both side members 4 and 4, respectively. There is. The upper surfaces of the engaging projections 6 and 6 are formed with inclined surfaces 6a and 6a that are inclined in the insertion direction with respect to the rod 1, so that they can be fitted easily when they are inserted. Further, the distance between the engaging projections 6 and 6 and the bottom plate portion 3a is equal to the distance between the end surface of the rod 1 and the engaging hole 2.

In the figure, 7 is a relief recess formed in the upper and lower members of the bottom member 3.

Now, in order to attach the bottom member 3 of the present embodiment configured as described above to the opening end surface of the rod 2, the elastically deformable pieces 4a, 4a of the both side members 4, 4 of the bottom member 3 are respectively inwardly moved. While elastically deforming, the bottom plate portion 3 of the bottom member 3
The opening end surface of the rod 2 is brought into contact with and fitted to the protruding surface of a. In this fitted state, the engaging projections 6 and 6 of the elastically deformable pieces 4a and 4a are connected to the rod 1. Engagement holes 2 and 2
On the other hand, the elastically deformable pieces 4a, 4a are automatically fitted and locked by the restoring elastic force to fix the both, that is, the bottom member 3 is fixed to the opening end surface of the rod 2, and the removal thereof is engaged. The protrusions 6 and 6 are engaged with the engagement holes 2 and 2 to prevent the protrusions 6 and 6 from being engaged, so that a reliable fixed state is obtained.

Then, at the time of the above-mentioned fitting, the inclined surface portions 6a, 6 which are inclined in the insertion direction with respect to the rod 1 are provided on the upper surfaces of the engaging projections 6, 6.
Since a is formed, the fitting work can be facilitated.

(Effect) As described above, according to the present invention, the bottom member is a bottomed member fitted to the end of the rod such as a box measure, and has an outer shape that substantially matches the cross-sectional shape of the rod. At least both side members are elastically deformable, and an engaging projection is formed on a part of the both side members, while an engaging hole is formed in a side surface of the rod body so as to form an end of the rod body. When the bottom member is fitted to the portion, the engaging projections of the both side members are fitted to the engaging holes of the rod by applying elastic force, so that the rod can be fitted without using a special material. Since the bottom member can be easily assembled to the end portion, the workability can be improved and the cost can be reduced.
