Abstract

PROBLEM TO BE SOLVED: To provide a slide type handle mechanism compacting a handle receiving size by preventing an interference between projections disposed on the handle and a connection member disposed between a pair of main body arms. SOLUTION: A slide arm 11 can be slid with respect to a main body arm 9. A lock member 20 having a partially opened ring-like lock portion 21 is attached to each of a pair of main body arms 9. A pair of lock pieces 26 are disposed at the opened end of the lock member 21, and a connection bar 50 is movably inserted into the lock pieces 26. An operation lever 60 is disposed on the connection bar 50 in a state capable of being rotated on a rotation pin 52. A connection member 40 is disposed on the lock portion 21 and the lock piece 26 on the side faced to the other lock portion 21. A depressed escape portion 41 is disposed in the connection member 40 so as not to interfere with an electric cord 3b and an electric source socket 14 which are disposed on a front surface portion 12a of a handle 12. Thereby, the handle 12 can be slid and received up to a position where the front surface portion 12a of the handle 12 is brought into contact with a connection member 40.

Here, the handle 12
Since the electrical cord 13b and the power supply socket 14 provided on the front surface 12a of the first member 12 and the mounting position of the connecting portion 40 with respect to the lock portion 21 are in the same plane, the connecting portion 40
When the handle 12 is stored by contracting the slide arm 11, a concave relief portion 41 is provided at a portion facing the electric cord 13b and the power socket 14 so as not to interfere with the electric cord 13b and the power socket 14. Is provided. A connecting rod 50 is provided inside the connecting part 40, and both ends of the connecting rod 50 are connected to each lock member 20.
Through a hole 27 provided in the pair of lock pieces 26. A stopper 51 is provided at one end of the connecting rod 50, and an operating lever 60 for locking or unlocking the slide of the slide arm 11 with respect to the main body arm 9 is provided at the other end of the connecting rod 50. To be rotatable. A round bar, a square bar, or the like can be used as the connection bar 50. The operation lever 60 is
To unlock the slide, the arrow 70 in FIG. 4 is used. To lock the slide, the arrow 71 in FIG. 5 is used.
Is turned in the direction of. The operation lever 60 is provided with a convex pressure portion 62 and a pressure release portion 63. Further, a portion 61 of the operation lever 60 corresponding to the lock portion 21 is formed in substantially the same shape as the outer periphery of the lock portion 21, and when the operation lever 60 is turned to the lock position, as shown in FIG. Is stored. In addition, the electric cord 13b and the socket 14 correspond to the protrusion of the present invention.

Next, the operation of the sliding handle mechanism of the present invention will be described. The operation lever 60 is moved to an arrow 7 in FIG.
When rotated in the direction of 0, since the distance from the rotation center of the depressurizing portion 63 is smaller than the distance from the rotation center of the pressing portion 62, the pressing force applied to each outer lock piece 26 is reduced. become weak. As a result, the inner diameter of each lock portion 21 increases, and the holding of the slide arm 11 by the lock portion 21 is released, so that the lock of the slide of the slide arm 11 with respect to the main body arm 9 is released. In this state, the slide arm 11 is slid in the direction of the arrow 30 in FIG. 2 to adjust the handle 12 to the storage position. Thereafter, when the operation lever 60 is rotated in the direction opposite to the arrow 70 in FIG. 5, the pressing portion 62 of the operation lever 60 and the stopper 51
Accordingly, the outer portion of the lock piece 26 of each lock member 20 is pressed in the direction of the arrow in FIG. At this time, since the inner portions of the lock portion 21 and the lock piece 26 are connected by the connecting portion 40, the outer lock pieces 26 are pressurized with substantially the same pressing force. Thereby, each lock portion 21
The inner diameter of the lock arm 2 is reduced,
1, the slide of the slide arm 11 with respect to the main body arm 9 is locked. Here, the connecting portion 4
0 is provided with a concave relief portion 41 on the upper surface,
When the handle 12 is slid to the storage position, the electric cord 13 b and the power supply socket 14 provided on the front surface 12 a of the handle 12
, So that the electric cord 13b and the power supply socket 14 do not interfere with the connecting portion 40. For this reason, the handle 12 can be contracted to a position where the front portion 12a of the handle comes into contact with the connecting portion 40, and the size of the handle when stored can be reduced.

In the above embodiment, the entire upper surface of the connecting portion 40 is concavely recessed to form the relief portion 41. However, the configuration of the relief portion is not limited to this, and the electric cord 13b and the power supply socket 14 are respectively provided. It is sufficient that interference can be prevented by, for example, denting or punching a portion facing the surface. Further, the operation lever 60 is not limited to the configuration of the embodiment, and the shape, the rotation direction, and the like can be variously changed as long as the inner diameter of the lock portion 21 can be changed.
The shape, length, position, and the like of the slit 23 provided between the lock portion 21 and the mounting portion 22 of each lock member 20 can be variously changed. Further, the slit 23 can be omitted. Further, a pair of lock pieces 26 is provided at the opening end of the lock portion 21 of the lock member 20, but the inside lock piece may be omitted. Further, although the mounting portion 22 and the mounting piece 25 are used as mounting means for mounting the lock member 20 to the main body arm 9, various mounting means can be used as the mounting means. Further, although the inner diameter step 28 is provided at the boundary between the lock portion 21 and the mounting portion 22, the inner diameter step 28 can be omitted. Further, the lock portion 21 is formed in a ring shape, but the shape of the lock portion 21 is not limited to the ring shape, and any shape may be used as long as the inner diameter can be changed so as to hold the main body arm 9 or the slide arm 11. Although the stopper 51 is provided at one end of the connecting rod 50, one end of the connecting rod 50 may be attached to the lock piece 26. In addition, the sliding handle mechanism of the lawn mower has been described, but the present invention can be used as a sliding handle mechanism in various devices other than the lawn mower.
