A tool with a structure, a driver (32) that reciprocates along an axis between a returned position and an extended position and a bumper (2100) that is coupled to the structure so as to be disposed between the structure and the driver. The bumper includes a beat piece (2110) and a damper (2112).

In a steering wheel, when a driver rotates a rotating section 126 in either direction, a protruding section 1241 bends an elastic member 1218b, and a tip of the elastic member 1218b depresses a button of a switch 1217b. As a result, the switch 1217b outputs a signal. Also, the reaction force produced as soon as the button is depressed causes a force in the reverse direction to be exerted on a hand of the driver. Thus, the driver can sense that the button is depressed.

An article having a first member and a second member that is molded onto the first member. The first member includes an aperture and an interior flange that extends at least partially about the aperture. The interior flange includes a pair of abutting surfaces. The second member is molded onto the interior flange and at least partially fills the aperture. Shrinkage of the second member following its molding onto the interior flange applies a force to the abutting surface that couples the second member to the interior flange. A method for forming an overmolded article is also provided.

A hand-held tool with a backbone (14), a motor assembly (18) that is mounted to the backbone, and a plastic housing (12). The motor assembly includes a driver (32) and is selectively actuatable to translate the driver along an axis. The plastic housing is coupled to the backbone and shrouds at least a portion of the backbone.

A tool with a driver (32), a motor (40), a structure to which the motor is coupled and a return cord (1052) assembly. The driver that is translatable along an axis between an extended position and a retracted position. The motor is configured to translate the driver from the returned position to the extended position. The return cord assembly is coupled to the driver and the structure and includes a spring (1082) and an elastomeric return cord (1080) that are employed to return the driver from the extended position to the retracted position.

The invention relates to a closing device consisting of a grip housing (10) containing a pivotably mounted grip flap (12). Said grip flap (12) is loaded by means of a restoring force (38) in the direction of its neutral position (12.1), against which force the manual actuation of the grip flap (12) must be carried out. Furthermore, an electrical switch (20) is associated with the grip housing (10), said switch comprising a spring-loaded (28) contact actuator (24). In order to provide a compact, cost-effective closing device, the restoring force (38) of the grip flap (12) can be directly generated by the spring-loading (28) of the contact actuator (24) of the electrical switch (20). In this way, separate springs are not required for the grip flap (12).

The invention refers to a new device capable of allowing the electric current to pass or be interrupted to the electric motor working small household appliances of the type constantly held by the user and operated by the pressure of the hand exerted on the outside part of the handle of the appliance, the handle being able to open and close enough to allow the contacts of a microswitch arranged inside the handle to connect or separate.
摘要:
A table lamp incorporates a switch (64) operating device consisting of two members (4, 30), one member (1) being located in the base (1) of the lamp and the other in the stem (11). The stem (11) is mounted in the base (1) for rotational movement between first and second positions representing "on" "off" positions of the lamp switch. The member (4) located in the base (1) includes a horizontal annular portion (60) from which projects two upwardly directed triangular shaped cam surfaces (61, 62) positioned at either end of a diameter of the annulus. One end of a spring loaded plunger (65) projects through the annular portion (60) between the cam surfaces (61, 62) and the other end acts, when depressed, to close the contacts in a micro-switch (64) located in the base (1). The other member (30) located in the stem (11), includes a surface adjacent and parallel to the annular portion from which depend two spring loaded plungers (35, 36) spaced apart to co-operate with the cam surfaces (61, 62) such that rotation of the stem (11) with respect to the base (1) causes movement of the plungers (35, 36) over the cams (61, 62) from one side to the other i.e. between the first and second positions. A stop means (54, 70) is provided to restrict the degree of rotational movement. A third plunger (50) depends from the surface of the second member (30) and is positioned such that when the members are in the first position it acts to depress the plunger (65) in the first member (4) so that the switch (64) is "on", and when the members are in the second position it is out of contact with said plunger so that the switch (64) is "off".
摘要:
The invention relates to a power tool, especially an angle grinder, comprising at least one grip housing (14a; 14b), at least one switching unit (16a; 16b), having at least one latch element (18a; 18b) arranged on the grip housing (14a; 14b), and at least one bearing unit (20a; 20b) designed to mount the latch element (18; 18b) such that it is mobile at least with respect to the grip housing (14a; 14b). According to the invention, the bearing unit (20a; 20b) is designed to guarantee, when the latch element (18a; 18b) is actuated, a stroke movement of the latch element (18a; 18b) along a trajectory of a value greater zero, starting from an end (24a; 24b) of the latch element (18a; 18b) closer to the connecting region (22a; 22b) of the grip housing (14a; 14b) in the direction of an end (26a; 26b) of the latch element (18a; 18b) away from the connecting region (22a; 22b), which end can be gripped.
