Description

  The present invention relates to a portable device mounting apparatus for mounting a portable device such as a lighting device to a bicycle or the like, and a lighting device including the same.

  Today, miniaturization and power saving of portable devices such as lighting devices, mobile phones, PDAs, transceivers, navigation devices, and various accessory devices (for example, portable inflaters) and battery life are being promoted. In particular, lighting devices use LEDs as light sources to promote downsizing, weight reduction, and power saving. In this way, portable devices, especially lighting devices, that are smaller and lighter and more energy-saving can be used on bicycles, motorcycles, automobiles, etc. and their accessories for the purpose of safety, convenience, comfort, etc. Or it is requested | required socially to attach as an accessory.

  As mounting devices for conventional lighting equipment, for example, mounting devices disclosed in JP-A-10-7050, JP-A-2001-278145 and the like have been developed and marketed. Such a conventional mounting device for lighting equipment includes a holder portion for winding around a bicycle handle and an attaching / detaching mechanism for mounting the lighting equipment.

Japanese Patent Laid-Open No. 10-7050 JP 2001-278145 A JP 2001-233264 A Japanese Patent Laid-Open No. 2002-284061

  The above-mentioned conventional mounting device for lighting equipment that can be attached and detached without a tool has a weak fastening force to the handle of the bicycle and causes unintentional dropout, rotation, or movement due to vibrations that occur when the bicycle is running. There is a fear.

  Moreover, it is difficult for the conventional mounting device for a lighting device to freely change the direction of the lighting device. The mounting device for lighting equipment disclosed in Japanese Patent Application Laid-Open No. 2002-284061 can tilt the lighting equipment up, down, left and right, but its tilting angle range is limited, and for example, it is difficult to face back. is there. A lighting device attached to a bicycle is used to irradiate the front as a general rule, but it may be preferable to irradiate the side or the rear from the viewpoint of safety and convenience. However, the conventional mounting apparatus for lighting equipment cannot cope with irradiation in such an arbitrary direction.

  Furthermore, the conventional attachment device for lighting equipment can only be attached to a handle of a bicycle or the like, and is not intended to be attached to, for example, a front basket or a helmet. In addition, the conventional attachment device is for lighting equipment, and is not intended for attachment of other portable devices such as mobile phones, PDAs, transceivers, navigation devices, and various accessory devices.

  The present invention has been made in view of these disadvantages, and can be fastened to a mounting location without a tool, and the horizontal direction and the inclination angle of the mounted portable device can be arbitrarily adjusted. An object of the present invention is to provide a portable device mounting apparatus having a variety of objects.

The invention made to solve the above problems is
(A) a bolt having a head portion and a shaft portion;
(B) a lever that is pivotally supported with respect to the head of the bolt so as to be rotatable about the axial direction (the direction of the central axis of the axial portion) and the vertical direction;
(C) a pair of belt bases slidably fitted to the middle part of the shaft part of the bolt;
(D) a belt that is stretched over a pair of belt bases and wound around a portion to be attached;
(E) a nut that is screwed into the tip of the bolt shaft, and the lever is
(F) an attachment / detachment mechanism for attaching the portable device;
(G) A portable device mounting device having a cam mechanism that pushes one belt base toward the other belt base by the rotation of a lever whose central axis is perpendicular to the axial direction of the bolt. .

  The portable device attachment device is wound around a place to be attached by a belt spanned between a pair of belt bases, and rotates a nut with respect to a bolt shaft and / or a lever with a bolt axial direction as a central axis. (Hereinafter referred to as “horizontal rotation”), the distance between the pair of belt bases is reduced, and further, the rotation of the lever (hereinafter referred to as “vertical rotation”) centered on the direction perpendicular to the axial direction of the bolt and the cam mechanism By pushing the belt base toward the other belt base, the belt base can be firmly fastened to the attachment location. Further, the portable device mounting apparatus can arbitrarily adjust the horizontal direction and the inclination angle of the portable device mounted on the lever by the horizontal rotation and vertical rotation of the lever. Further, since the portable device mounting apparatus uses a belt for mounting to the mounting location, it is not limited to a bicycle handle and can be fastened to various mounting locations. In addition, the portable device mounting apparatus can cope with mounting of any portable device by adjusting the shape of the lever having the attaching / detaching mechanism.

  The cam mechanism includes a disk-shaped plate cam portion disposed perpendicular to a shaft support shaft (a central axis of rotation by the shaft support) on the shaft support portion of the lever, and the shaft support shaft of the lever is a plate cam portion. It should be eccentric from the center. According to such a cam mechanism, the belt base on the head side can be pushed to the other belt base side according to the vertical rotation of the lever with a simple structure in which the plate cam portion is attached to the shaft support portion of the lever.

  The belt has a pair of belts extending from a pair of belt bases, and has an engaging part into which the other belt can be inserted at the tip of one of the pair of belts. The belt may have a check mechanism for locking the reverse movement of the other belt inserted into the engaging portion. According to the pair of belts having such an engaging means and a check mechanism, the adaptability of the attachment location is expanded.

  A cam base that is slidably fitted in the vicinity of the head portion of the shaft portion of the bolt is provided, and a cylindrical inner surface-like concave surface along the outer peripheral surface of the plate cam portion may be provided on the head portion side of the bolt in the cam base. As described above, by pushing the cam base having a concave surface along the outer peripheral surface of the plate cam portion directly below the lever of the bolt shaft portion, the pushing force to the belt base portion by the cam mechanism can be effectively transmitted.

  It is preferable to have a concavo-convex structure that can be fitted to the outer peripheral surface of the plate cam portion and the concave surface of the cam base. The uneven structure of the contact surfaces of the plate cam portion and the cam pedestal makes it possible to lock the lever at a predetermined angular position with respect to the cam pedestal and thus the shaft portion of the bolt, in other words, positioning of the lever at the time of fastening. Therefore, by having such a concavo-convex structure, the orientation of the portable device mounted on the lever can be fixed when the portable device is mounted by the portable device mounting apparatus, and as a result, the portable device caused by vibration of the bicycle or the like. Direction change and a decrease in fastening force of the portable device mounting apparatus can be reduced.

  As the concavo-convex structure, a hemispherical convex portion formed on the outer peripheral surface of the plate cam portion and a concave surface of the cam base are formed substantially parallel to the central axis direction of the concave surface (the central axial direction of the cylindrical inner surface formed by the concave surface). It is preferable to have a recessed strip portion. Thus, the plate cam portion and the cam pedestal due to the vertical rotation of the lever are configured by forming a concavo-convex structure from the hemispherical convex portion formed on the outer peripheral surface of the plate cam portion and the concave stripe portion formed on the concave surface of the cam pedestal. Can be easily and reliably engaged.

  It is preferable that at least the concavo-convex structure of the plate cam portion and / or the cam base is formed from a synthetic resin. Thus, by forming at least the uneven structure of the plate cam portion and / or the cam base from synthetic resin, the engaging portion of the plate cam portion and the cam base has a predetermined elastic deformability. Therefore, at the time of fastening to the mounted portion by horizontal rotation of the lever described above, the cam mechanism exerts a pushing force downward on one belt base, while the concave portion of the cam base and the plate cam portion are It becomes easy and reliable to fit the hemispherical convex portion.

  A washer made of an elastomer material that fits between the cam base and the nut in the shaft portion of the bolt may be provided. Since the washer made of an elastomer material that is externally fitted between the cam base and the nut of the bolt shaft portion has an elastic deformability, when the above-mentioned lever is fastened to the mounting position by horizontal rotation, one belt is used by the cam mechanism. It is easy and reliable to fit the concave portion of the cam base and the hemispherical convex portion of the plate cam portion while applying a downward pressing force to the base portion.

  Accordingly, the lighting device provided with the portable device mounting device can be fastened to a mounting location such as a bicycle handle without using a tool such as a screwdriver, and the direction of lighting can be arbitrarily adjusted. For example, it can be fastened to various attachment points such as a front basket and a helmet.

  Note that the vertical, horizontal, horizontal, and vertical directional relationships used in the description of the present invention indicate the directional relationship in a state where the bolt is positioned vertically with its head positioned upward.

  As described above, the portable device mounting apparatus of the present invention can be fastened to a mounting location without a tool, and the horizontal direction and the inclination angle of the mounted portable device can be arbitrarily adjusted. Has a wide variety of objects. Moreover, the illuminating equipment provided with the attachment apparatus of this invention can be attached much firmly without a tool, and can irradiate arbitrary directions, such as a side and back. Accordingly, the portable device mounting apparatus and the lighting device including the same can promote safety, convenience, comfort, and the like when driving a bicycle, a motorcycle, an automobile, or the like.
