Description

  The present invention relates to a device fixing device and a fixing attachment.

Conventionally, for example, an infant apparatus such as a merry-go-round is attached to a crib, which is a fence, for use. In this case, a fixing device for attaching the device to the upper frame (cross member) of the crib is required. Patent Document 1 discloses a fixing device for infant equipment in a crib.
The fixing device of Patent Document 1 has an inverted U-shaped member having an open lower end, and a pressing piece on the inner end of an external thread that is screwed into an internal thread that horizontally penetrates one leg piece of the inverted U-shaped member. Is provided, and an operating portion is provided at the outer end of the male screw.

The pressing piece 34 is formed in a cup shape whose front end is flush with the surface perpendicular to the axis of the male screw 32, and is free to rotate with respect to the male screw 32.

3. Attachment 40 for fixing
Moreover, the fixing device 30 includes a fixing attachment 40 that constitutes a pressing plate. This fixing attachment 40 is formed in a horizontally long oval shape in front view (FIG. 4A). The upper half 40a of the fixing attachment 40 is a thick part, and the lower half 40b is a thin part. The lower half 40b is formed below the front part of the upper half 40a.
A first pressing portion 41 is formed on the front side of the upper half portion 40a. Specifically, a concave portion having a U-shaped cross section is formed in the upper half portion 40a over the entire width direction. The recess has a shape that can accept at least a part of the upper rail 51 and has an inner surface corresponding to the outer periphery of the upper rail 51 having a round bar shape. In this case, for example, when the side wall 53 is made of cloth or the like, the upper end portion of the outer surface of the side wall 53 is inclined as shown in FIG. It is preferably formed in an arcuate surface so as to correspond to a curved surface or a flat surface from the lower half of the recess to the lower opening edge of the recess so as to match the outer surface of the side wall 53 (FIG. 6). If it does in this way, it will become possible to clamp in the wide range, without damaging the side wall 53. FIG. At this time, the portion extending from the lower half of the recess to the lower opening edge of the recess sandwiches the side wall 53 and functions as the second pressing portion 46.
As shown in FIG. 4, a pressing pad 42 made of an elastic material such as rubber or urethane is attached to the inner surface of the recess. The pressing pad 42 is provided so as to protrude from the bottom inner surface of the recess. The pressing pad 42 is preferably formed of a material having elasticity and a large frictional resistance. In addition, it is also possible to form the fixing attachment 40 itself with an elastic material without providing the pressing pad 42.

On the other hand, as shown in FIG. 6A, when the apparatus case 10 is fixed to the upper frame 51 of the crib 50 having the round bar-shaped upper frame 51 and the side wall 53 below the upper frame 51, the device case 10 is fixed. Attachment 40 is used.
In this case, the rear surface of the device case 10 and the suspended portion 31b of the bowl-shaped portion 31 are opposed to each other with the upper rail 51 and the side wall 53 interposed therebetween, and then the fixing attachment 40 is suspended from the upper rail 51 and the side wall 53. It interposes between the part 31b. At that time, the cutout portion 43 on the upper surface of the upper half portion 40a of the fixing attachment 40 and the horizontally extending portion 31a of the hook-shaped portion 31 are fitted together. By this fitting, the fixing attachment 40 is positioned.
Alternatively, after fitting the notch 43 on the upper surface of the upper half 40a of the fixing attachment 40 and the horizontal extension 31a of the bowl-shaped portion 31, the rear surface of the device case 10, the upper rail 51, and the side wall 53 The front surface of the fixing attachment 40 is made to face each other.
Thereafter, the operation portion 33 is rotated, the pressing piece 34 at the tip of the male screw 32 is applied to the pressed portion 45, and the operation portion 33 is further rotated so that the upper rail 51 is interposed between the fixing attachment 40 and the rear surface of the device case 10. And the device case 10 is fixed to the upper crosspiece 51 by sandwiching the side wall 53.

5. Effects of the Embodiment According to the fixing device 30 configured as described above, the following effects can be obtained.
That is, when the attachment 40 for fixing is not attached, the device case 10 can be attached to the upper cross-piece 51 having a square cross section or a rectangular cross section. On the other hand, if the attachment 40 for fixation is used, the apparatus case 10 can be firmly attached to the upper bar 51 of a round bar shape.
In the latter case, the side wall 53 is sandwiched between the second pressing portion 46 and the rear surface of the device case 10, so that the device case 10 is pulled upward or rotated around the upper rail 51 of the device case 10. Be blocked. Furthermore, since the first pressing portion 41 is in surface contact with the outer periphery of the upper bar 51 having a round bar shape, movement of the upper bar 51 in the longitudinal direction and movement in the vertical direction is reduced, and the device case 10 can be stably fixed.
