Abstract:
L'invention concerne un dispositif de fixation des instruments comportant un fût tournant (5) destiné à recevoir l'instrument et l'entraîner en rotation caractérisée en ce qu'il comporte, d'une part un dispositif ayant au moins un ergot (11) élastiquement escamotable perpendiculairement par rapport à l'axe du logement de l'instrument jusqu'à ce qu'il puisse s'engager dans la gorge d'accrochage (2) assurant ainsi la rétention axiale de l'instrument, et d'autre part un taquet (13) solidaire en rotation du fût tournant et qui en combinaison avec le fût tournant donne la forme combinée à celle du méplat d'entraînement (3) de la queue de l'instrument qui a pour particularité de s'effacer radialement ou longitudinalement si le méplat est correctement orienté reprend la position dans laquelle il assure l'entraînement en rotation de l'instrument. Le méplat de l'instrument venant généralement prendre la position adéquate lors de la rotation dès que le moindre effort en rotation lui est appliqué. L'instrument est libéré par action sur un bouton pression (17) par exemple, qui commande l'écartement ou l'effacement radial de l'ergot.
Abstract:
A holder (100', 100'', 100''', 100 ) having a quick-connect mechanism actuated by inserting a single- or double-ended tool bit (300, 300', 300'', 300''', 300 , 300 ), the tool bit engaging means to force deflection of retaining means (170', 170'', 176, 700, 700', 800), where the retaining means actuate means for engaging the tool bit, and released by manual operation of the retaining means, whereby the tool bit is pushed out from the holder so that the user can operate the tool bit holder using one hand only.
Abstract:

A connector having at least one open end and an elongated slot with a floor and a pin guide through the floor is further disclosed. The pin guide is open to the inside of the connector. Between the sleeve and the slot is a pin having a pin head visible through the elongated guide and two opposing spring arms of a size and shape to fit in said slot, and a pin body which movable fits in side pin guide.
Abstract:
A lug nut removal and storage system, for removing lug nuts (11) from lug bolts (13), comprising a tube (10). The tube (10) has a tube exterior (10E), a proximal end (10P), a distal end (10D), and a proximal distal axis. A channel (12) extends into the distal end (10D) wherein the lug nuts (11) are stored. A plurality of ball bearings (16) are disposed around the channel (12) near the distal end (10D). The ball bearings (16) rest in ball bearing bores (24) transverse to the channel (12), the ball bearings (16) move within the ball bearing bores (24) to narrow and widen the channel (12). A spring clip (18) selectively restricts the outward movement of the ball bearings (16), so they will maintain the lug nuts (11) in the channel (12), and releases the ball bearings (16) to widen the channel (12) sufficiently to release the lug nuts (11). A main spring (28) extends within the channel (12) to bias the lug nuts (11) against the ball bearings (16).
Abstract:
A die chuck for multiple-cornered ends of tool spindles comprises a bushing (5) for transmitting the driving force, the cavity (8) of which matches the multiple-cornered cross-section of the end (32) of the spindle. A pressure piece in the form of a ball (22) which acts on the spindle is lodged in a window-shaped perforation in the bushing (5). Behind the ball (22) is a spring-loaded actuating socket (11) with an inclined clamping surface (19) which presses on the ball and which is located in front of supporting shoulders in the region of the internal peripheral edge of the perforation (23). To obtain an optimal standard shape, the ball (22) is arranged in a cavity (8) which passes through one of the multiple corners (24) and is in two-point contact with the prismatically disposed surfaces of a corner recess (31) at the end (32) of the spindle of the tool (29).
Abstract:
Eine Handwerkzeugmaschine hat einen Elektromotor 7 und eine Abtriebsspindel 1, die von dem Elektromotor 7 um einer Arbeitsachse 18 drehend antreibbar ist. Die Abtriebsspindel 1 hat einen längs einer Arbeitsachse 18 orientieren, abtriebsseitig offenen, zylindrischen oder prismatischen Aufnahmeraum 16 zum Aufnehmen eines Werkzeugs 11 entgegen einer Entnahmerichtung 20 und zwei in den Aufnahmeraum 16 in radialer Richtung einstechende Langlöcher 19. In den Langlöchern ist jeweils ein Sperrkörper 12, der in dem Langloch 19 liegend in den Aufnahmeraum 16 hineinragt und zwischen einem abtriebsseitigen Ende 22 des Langlochs 19 und einem antriebsseitigen Ende 21 des Langlochs 19 beweglich ist. An einem radialen Anschlag 26 in radialer Richtung anliegend ist der Sperrkörper 12 in den Aufnahmeraum 16 eingreifend gezwungen. Der Anschlag 26 überlappt in einer verriegelnden Stellung mit den abtriebsseitigen Enden 22 der Langlöcher 19 und ist in Entnahmerichtung 20 gegen eine Federkraft einer Feder 23 zum Freigeben einer radialen Bewegung des Sperrkörpers 12 aus dem Eingriff mit dem Aufnahmeraum 16 verschiebbar. Eine Feder 23 hat einen Stützring 29, zwei von dem Stützring 29 in Entnahmerichtung 20 vorstehende und kreissegmentförmig um den Aufnahmeraum 16 gebogene Bügel 30 und jeweils von jedem der Bügel 30 einen in Entnahmerichtung 20 vor dem Sperrkörper 12 in das Langloch 19 radial eingreifenden Stift 36.
Abstract:
A "snap-in" bit chuck assembly (10) for a rotary hand or powered tool, includes a body (20) having a hex shank (22) at its rearward end, a retraction collar (30) slidably disposed on the body (20), and an outer retaining collar (70) fixed to the forward end of the body (20). The body (20) has a coaxial hex socket (24) formed therein to allow a tool bit (14) to be inserted thereinto. A slot (50) is formed in the body (20), between the outer surface of the body (20) and the internal hex socket (24). A coil spring (40) surrounds the body (20), inside the retraction collar (30), and normally biases the retraction collar (30) forwardly and biases a retaining clip (60) toward the bottom of the angular slot (50).
Abstract:
A chuck mechanism (21) for holding rotating tools in gear driven or turbine driven medical/dental devices (1). The chuck includes a bur tube (37) which releasably receives a shaft (24) of a dental tool (23), a tilt plate (55) which extends through the bur tube (37) and which has a hole (61) through which the tool (23) extends, and a tilt plate pusher (85) which is moveable axially with respect to the bur tube. The tilt plate (55) is moveable between a first, unlocked, position in which the edges of the tilt plate hole are spaced slightly from the dental tool shaft so that the shaft may be freely moved axially relative to the tilt plate, and a second, locked, position in which the tilt plate edges contact the shaft to prevent axial and rotational movement of the shaft relative to the tilt plate. The tilt plate is preferably spring biased to its locked position, and the tilt plate pusher is preferably operated by a push button (105) to move the tilt plate to its open position. In another embodiment, the tilt plate is positively held in its locked position by a threaded piece (85''').
