Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an adjustable spanner.

(Summary of the Invention) The present invention provides an adjustable spanner. That is,
the adjustment spanner; first and second jaw members that each define first and second generally parallel jaw surfaces and are slidable relative to each other to adjust the distance between the jaw surfaces; a first jaw member; a first wedge surface limited to; a second wedge surface limited to the second jaw member; and an internal wedge surface that supplements the wedge surface of the jaw member, the internal wedge surface being engaged with the wedge surface of the jaw member. and a locking member that prevents separation between the jaw surfaces by wedge-locking the locking member.

A preferred embodiment of the invention comprises three mutually slidable members, and the adjustment arm slides the jaw members relative to each other to set the required spacing between the jaw surfaces. In particular, it can be configured to any required dimensions. The locking member is then slid into engagement with the wedge surface of the jaw member to lock the jaw member against separation of the jaw surfaces.

In a preferred embodiment of the invention, the wedge surfaces of the jaw members are defined at a slightly acute angle with respect to each other. By applying finger pressure to the locking member, the locking member moves the second jaw member relative to the first jaw member, thereby allowing the wrench to be adjusted from the widest condition to the narrowest condition. Preferably, the second jaw member is spring biased against the first jaw member in a direction in which the jaw surfaces are separated. Accordingly, by applying finger pressure to the locking members such that the locking members are moved in such a way that the spring force separates the jaw members, the jaw members can be moved in the direction of separation from each other.

An embodiment of the present invention will be described below with reference to the drawings.

(Example) The adjusting spanner 1 includes a first jaw member 2 and a second jaw member 3, which define substantially parallel jaw surfaces 4, 5, respectively.

The jaw members 2, 3 are slidably engaged with respective horizontal surfaces 6,
7 so that the jaw member 3 can be slid along the horizontal surface 6 of the jaw member 3 so as to change the spacing between the faces 4,5.

A first pA surface 8 is provided on the first jaw member and a second
A wedge surface 9 is provided on the second jaw member. The wedge surface 8.9 is
The tilt angle is limited to 11.25 degrees. The locking member 10 has internal wedge surfaces 11 , 12 , which correspond to the wedge surfaces 8
, 9 is limited. Locking member 1
0, the internal wedge surface 1 engages with the wedge surface 8 over the entire surface, and the internal wedge surface 12 engages with the wedge surface 9 over the entire surface. It can be placed while In this arrangement, the jaw members 2° 3 are locked against movement in the direction of pulling the jaw surfaces 4, 5 apart.

Manual pressure applied to the locking member 10 generally in the direction of arrow A causes the jaw member 3 to slide along the horizontal surface 6 of the jaw member 2 so as to reduce the space between the faces 4,5.

Preferably, the jaw member 3 has a generally T-shaped slot 13 in which a generally T-shaped pin 14 secured to the jaw member 2 is housed. The compression spring has jaw surface 4,
It is mounted between the terminal end 15 of the slot 13 and the pin 14 so as to bias the jaw members against the jaw members 2 in a direction that causes the jaw members 5 to separate. Accordingly, finger pressure applied to the locking member 10 in a direction opposite to the direction of arrow A will move the locking member away from the jaw surface 4 and the compression spring will cause the jaw member 3 to move towards the neck 4,5. Can move away from you.

Claims (8)

[Claims] (1) first and second jaw members each defining first and second substantially parallel jaw surfaces and capable of sliding against each other to adjust the distance between the jaw surfaces; a first wedge surface limited to the second jaw member; a second wedge surface limited to the second jaw member; and a respective internal wedge surface corresponding to a wedge surface of each jaw member; An adjustable spanner comprising a locking member that engages a wedge surface of the member and prevents separation of the jaw surface by the wedge. (2) the wedge surfaces of the jaw members are limited to a slightly acute angle with respect to each other;
By applying finger pressure to the locking member, the locking member moves the second jaw member relative to the first jaw member so as to reduce the gap between the jaw planes, and the gap between the jaw planes changes from the widest state to the narrowest state. An adjustable wrench according to claim 1, which can be adjusted to any position. (3) The adjustable spanner according to claim 2, wherein the angle of the wedge surface is about 11 degrees. (4) The jaw members are slidably engaged by mutual engagement of substantially horizontal horizontal surfaces perpendicular to the jaw surface, and the wedge surfaces of the first and second jaw members are An adjusting spanner according to any one of the above claims, which faces a horizontal surface at substantially equal angles. (5) the second jaw member is biased by a spring against the first jaw member in a direction in which the jaw surface is moved away, and applies finger pressure to the locking member to move the locking member;
