[Industrial applications]

 The present invention relates to a belt clip for attaching a portable device to a belt.

[0002]

[Prior art]

 In the case of a portable device such as a wireless communication device, there are methods to operate it while holding it by hand or putting it in a pocket, or by mounting it on a belt or the like. When it is attached to this belt, a belt clip made separately from the portable device is attached to the portable device to hold the belt by sandwiching it between the portable device and the belt clip. The one formed in 1 was often used.

FIG. 3 is a perspective view showing a state where a conventional belt clip is attached to a wireless communication device. The figure will be described. The belt clip 1 is fastened and fixed to the wireless communication device 11 with two screws. Since the belt clip 1 is made of sheet metal, in the manufacturing process, deburring and polishing of the cut-out portion of the sheet metal are performed, and then plating and painting are performed, resulting in high manufacturing cost. Besides, the belt clip 1 is fixed with two screws, so the number of steps is increased, and in addition, the attached shape is often unbalanced in terms of design. Further, since the free end 3 of the belt clip 1 is bent to the outside so that it can be easily attached to the belt, the outer bent portion of the free end 3 is pressed against the body when attached to the belt. It will be. Further, the belt clip 1 made of metal may be bent when an inadvertent force is applied, and if it is deformed, the correction thereof is troublesome. Even when the belt clip 1 is attached to the wireless communication device 11 even when the belt is not attached to the belt, the bent portion of the free end 3 is a hindrance to the hand and is difficult to use.

[0004]

[Problems to be solved by the device]

 The metal belt clip to be mounted on the conventional portable device requires a lot of processing steps because it is formed of sheet metal, resulting in high cost. In addition, there is an unnatural appearance of the shape combined with the device when it is attached to a portable device, discomfort due to the shape of the belt clip when holding it in your hand, and discomfort when attached to the belt. It was The present invention solves these problems and aims to provide a belt clip that has a neat shape and is comfortable to use.

[0005]

[Means for Solving the Problems]

 The belt clip of the present invention is made by molding a synthetic resin, and has an elastic thickness with a curved plate-shaped outer surface, and one longitudinal end of the clip is screwed to a portable device. The mounting surface is thickly formed as the mounting portion. The mounting portion is provided with a rotation preventing projection that is inserted into the recess of the portable device, and further, one screw hole is provided on the outer surface side at a position where the top of the screw does not protrude. Since this belt clip is fastened with a single screw, the anti-rotation projection is necessary for stable fixation. The other end in the vertical direction is provided with a slip-off preventing protrusion when mounted on the belt as a free end, and in order to prevent deformation during molding by the protrusion shape of this slip-off preventing protrusion, A plurality of deformation preventing recesses are formed on the outer surface side portion. In addition, the structure is provided with a reinforcing rib that partially limits elasticity.

[0006]

[Action]

 If the anti-slip protrusions are projected on a part of the plate formed by molding, the shape will be deformed due to the difference in heat dissipation heat conduction due to the shape of the projecting part during molding and the difference in shrinkage time that occurs locally. There are cases. For this reason, a plurality of deformation preventing recesses are formed on the outer surface side of the detachment preventing projection portion. Since the recess increases the contact surface between the synthetic resin and the molding die, deformation due to sink marks can be suppressed.

When the belt clip is fixed to the portable device, the disengagement stopper is in contact with the portable device. Since the belt clip warps, it can be attached and detached, but a reinforcing rib that partially limits elasticity is formed to prevent it from warping too much.

[0008]

【Example】

 FIG. 1 shows the structure of a belt clip according to the present invention, (a) is a front view, (b) is a rear view, and (c) is a sectional view. The drawings will be described in detail. The belt clip 1 is integrally molded with a synthetic resin, and has a curved surface finish on the outer surface side. The one end 2 in the vertical direction is a mounting portion, and the mounting surface 4 is projected to form an air space through which the belt of the belt clip 1 passes. The mounting portion 2 is provided with one screw hole 5 for screwing to a portable device, and the screw hole 5 is provided with a recess so that the top of the screw does not protrude from the outer surface side. The belt clip 1 is fixed to the portable device with a single screw so that the belt clip 1 is not bent.

The other vertical end of the belt clip 1 is a free end 3 and is close to the free end 3 so that the belt clip 1 is fixed to a mobile device and is not accidentally detached from the belt. A detachment prevention projection 7 is provided on the mounting surface side. When the belt is attached to the belt, it can be attached to the belt by the thickness of the belt, so it can be attached so that the belt clip 1 is made thick enough to make the synthetic resin elastic. It has a raised shape near the free end 3, but when it is taken out from the mold for molding and cooled, a plate-like outer surface side opposite to the slip-out preventing projection 7 is dented, which is a common sink phenomenon. The shape changes. In order to suppress the deformation of the shape due to the sink mark, a plurality of deformation preventing recesses 8 are formed on the outer surface side opposite to the slip-off preventing projection 7. The purpose of forming the recess is to prevent deformation by widening the contact surface between the synthetic resin surface and the molding die. Further, the belt clip 1 is required to have elasticity, but it is sufficient if the belt clip 1 has enough elasticity to be attached to the belt, and therefore, it is unnecessary to provide the reinforcing rib 9 close to the mounting portion 2 to partially limit the elasticity. Suppresses elasticity.

FIG. 2 is a perspective view showing a state in which the belt clip 1 of the present invention is attached to the wireless communication device 11. In order to mount the belt clip 1, the wireless communication device 11 side needs a screw hole for screwing the belt clip 1 and a recess into which the anti-rotation projection 6 is inserted. The detent 6 of the belt clip 1 is inserted into the recess of the wireless communication device 11, and the mounting screw is screwed into the screw hole on the wireless communication device 11 side through the screw hole 5 to be mounted. The belt clip 1 can have a sense of unity by matching the color of the wireless communication device 11 side to which it is attached. In addition, when the belt clip 1 is attached to the hand and operated, it does not feel discomfort because it fits in the hand due to the curved outer surface, and there is no annoying bend when attached to the belt. Can be installed. Besides, the belt clip 1 does not bend and deform even if an inadvertent force is applied.

The belt clip 1 may be provided with a strap mounting hole 10 if necessary. In the usual method, the strap is attached to the portable device by attaching an annular component to the strap, and the strap is passed through the annulus, but according to the present invention, the annular component is also unnecessary.

[0012]

[Effect of device]

 According to the present invention, since the belt clip is made by molding the synthetic resin integrally, the unit price can be reduced to half or less as compared with the sheet metal belt clip. This belt clip has a structure that prevents deformation of the shape due to sink marks generated during molding by forming a plurality of recesses on the outer surface side opposite to the slip-out preventing projection provided at the free end on the side where the belt is mounted. ing. Also, since it is equipped with a rotation stopper so that it can be attached to a portable device with one screw, it can be attached stably and can be easily attached and detached. When used, this belt clip has many advantages such as a shape that the outer surface side of the belt clip is curved so that it fits in the hand and does not cause discomfort.
