Abstract

PURPOSE:To provide a handle grip with a pulse meter to be mounted on the handlebars of a bicycle, a bicycle type health machine or the like. CONSTITUTION:In a bicycle type handle grip 1 of cylindrical shape where fingers are directly touched when a rider is on, the handle grip is provided with a recessed part 2 where a pulse sensor 4 is mounted, a shade wall 3 which is mounted in the vicinity of the recessed part by being bent to the recessed part side, and a lead wire 5 connecting the pulse sensor to a pulse meter 7. Thus, it is unnecessary to hold the earlobe of a person whose pulse is measured and it is safe because the movement of the head is not limited. The fingers in measuring the pulse are positioned by the shade wall, and the fingers are brought into close contact with the grip by the shade wall. This constitution prevents the disturbance of the solar light or the like from being entering, eliminates the mistaken measurement, and the errors in measurement are small. The lead wire to mount the pulse meter and the sensor can be shortened, leading to sufficient protection against the noises and the accuracy of measurement is improved. In addition, when a lead wire passing part is provided in the grip, it is unnecessary to make a hole in a handle bar, and the insertion is facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle grip equipped with a pulse meter, which is attached to a handle of a bicycle, a bicycle type health machine or the like.

[0002]

2. Description of the Related Art Heretofore, in order to check the physical condition during training on a bicycle, the pulse rate is sometimes measured while the bicycle is running. In that case, the pulse sensor is fixed to the earlobe with a clip, and the pulse sensor and the pulse meter main body are connected by a lead wire. Further, there is disclosed a grip with pulse detection in which a handle grip is provided with a recess surrounded by a ridge, and a pair of a light emitting element and a photosensitive element are provided side by side on the bottom surface of the recess (Actual No. 59-140704).

[0003]

However, the above-mentioned conventional techniques have the following problems. In the former case, the lead line of the pulse sensor attached to the earlobe hangs down on the side of the body, and the direction of the face does not become free, so it is dangerous while running and turn the neck left and right. There is also a problem in that the clip easily comes off and the reliability of the measurement is affected, and the measurement is performed in a posture different from the actual posture while running.

FIG. 12 is a diagram showing the pulse rate measurement according to the prior art. In this way, the pulse rate sensor-S is attached to the earlobe of the person to be measured, and the lead line L is connected to the pulse rate meter M fixed to the handle H. For this reason, the person to be measured does not have a free orientation of the face at the time of measurement, and the measurement while running is dangerous.

On the other hand, in the latter case, it has been pointed out that sunlight penetrates through the gap between the finger and the edge of the recess, resulting in a large measurement error.

In both of these techniques, it is generally necessary to match the hole of the handle pipe with the hole of the grip in order to pass the lead wire through the handle pipe. There is also the problem that it is difficult to install.

[0007]

In view of the above points of the prior art, the present invention has solved the problems by adopting the following configuration. That is, the first aspect of the present invention is that a rider such as a bicycle or a bicycle-type health machine engages with a tubular bicycle-type handle grip that directly touches a finger when in use, and has a recessed portion for attaching a pulse sensor and the periphery of the recessed portion A bicycle-type handle grip, characterized in that it is provided with a pair of light-shielding walls, which are preferably bent toward the recess side, and a lead wire connecting between the pulse sensor and the pulse meter.

It is also possible to provide a pulsometer and a pulsometer on the handle grip portion. For this reason, a bicycle type in which a mounting protrusion fitted to the pulsometer is provided at a position visible to the rider. It is a handle grip.
Further, in the handle grip, it is preferable to form a lead wire passage portion, for example, a lead wire passage hole or a passage groove opened from the side wall of the recessed portion to the handle central end surface. Should be provided. The lead wire passing portion is a through hole or groove for wiring a lead wire connecting between the pulse sensor unit and the pulse rate meter, and the number of this through hole or groove is one or -Two or more may be provided to classify the cords.

A second aspect of the present invention is the above-mentioned recessed portion,
A bicycle-type handle characterized in that a ring-shaped body including a light-shielding wall, a pulse attachment protrusion, a lead wire passing portion, etc. is formed as a separate body, and the ring-shaped body is fitted into the outer periphery of the handle grip on the open end side. It is a grip.

The recess is a shallow hole for accommodating and fixing the pulse sensor unit. A pair of light shielding walls is preferably provided integrally with the handle grip around the recess. And, this light-shielding wall is usually arranged substantially parallel to the axis of the handle grip around the recess,
Provided integrally with the handle grip in a slightly bent state on the side of the recess, and when measuring the pulse by applying the finger to the pulse sensor of the recess, block the light entering from both sides of the finger, thereby making a measurement error. It will be reduced.

[0011]

According to the present invention, the pulse sensor mounting recess, the (a pair of) light shielding walls provided in the longitudinal direction of the recess, and the releasable from the side walls of the recess to the handle center side of the grip. A bicycle-type handle grip that consists of a wire passage hole or groove and, in some cases, both a pulse sensor and a pulse meter so that the pulse can be measured easily and safely during running and stopping. Is provided.
