BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle which can be suitably applied to medical equipment such as a surgical light and a tray table.

[0002]

2. Description of the Related Art FIG. 11 is a perspective view showing a typical prior art handle device 1, and a similar prior art is disclosed, for example, in Japanese Utility Model Laid-Open No. 49-55597. For example, a dental clinic is provided with a dental clinic, and the dental clinic is provided with a surgical light 2 as a medical device for illuminating a medical treatment site such as a patient's oral cavity. The surgical light 2 includes a main body 3 having a light source, a pair of substantially L-shaped arms 4 and 5 provided on upper and lower sides on both sides of the main body 3, and is detachably mounted between each pair of arms 4 and 5. The handle 8 in the form of a long rod is detachably mounted. One arm 4 has a convex portion 6, and the other arm 5 has a concave portion 7. The handle 8 has a gripping member 9 gripped by hand, and an operation member 12 attached to one end in the longitudinal direction of the gripping member 9. The operation member 12 is fitted with the protrusion 6. A mating hole 11 is formed, and a fitting projection 13 that fits into the recess 7 is formed in the gripping member 9. The operating member 12 is urged outward by the compression spring (not shown) in the direction of arrow A1 from the gripping member 9 in the axial direction in a state where the operation member 12 is prevented from being pulled out.

In a state where such a handle 8 is mounted between the arms 4 and 5, the fitting projection 13 fits into the recess 7 and
The projection 6 is fitted in the fitting hole 11. In this state, the surgeon or assistant grasps the handle 8 so that the medical treatment site such as the patient's mouth is well illuminated, and the patient or the assistant does not obstruct the patient's getting on and off the medical table. The light 2 can be moved. Since the handle 8 is frequently held in this manner, it is necessary to disinfect the handle 8. When performing this disinfection, the handle 8 is detached from the main body 3, but if the operation for removing the handle 8 is complicated, the operator unconsciously supports the main body 3 with one hand while holding the other hand. In some cases, an operation for detaching the handle 8 or an operation for detaching the handle 8 with both hands may occur. 12 can be displaced in the direction of the arrow A2 against the spring force of the compression member to release the fitting state between the projection 6 and the fitting hole 11, and the handle 8 can be removed from the main body 3 with one hand. It is configured as follows.

[0004]

In such a prior art, each of the arms 4 and 5 protruding from the main body 3 is provided with a convex portion 6 and a concave portion 7 as first locking means, and the handle 8 has a second portion. Since the fitting hole 11 and the fitting projection 13 are provided as locking means, in order to attach the handle 8 to each of the arms 4 and 5, the projection 6 and the recess 7 of each of the arms 4 and 5 are provided. In a state where the handle 8 is inclined with respect to the axis connecting the two, the protrusion 13 of the handle 8 is fitted into the recess 7 of the arm 5 while the operating member 12 is
Is drawn in the direction of arrow A2 so that the fitting hole 11
It is necessary to perform a series of operations in which after the finger is accurately positioned, the finger is released from the operation member 12 to return in the direction of the arrow A1. That is, since the grips 8 having substantially the same length as the gaps have to be fitted between the arms 4 and 5, there is a problem that the mounting work of the grips 8 is troublesome. When the handle 8 is connected to each of the arms 4 and 5, the handle 8 and each of the arms 4 and 5 are close enough to reach the fingers while holding the handle 8. The fingers easily come into contact with each other and the arms 4 and 5 may be soiled, and the fingers that have contacted the soiled arms may also be soiled. In addition, since the arms 4 and 5 are fixedly provided on the main body 3, the arms 4 and 5 cannot be removed from the main body 3 together with the handle 8, and therefore, must be disinfected separately from the handle 8. There is a problem that convenience is poor.
