    DRILLING SUPPORT
    TECHNICAL FIELD The present invention relates to an apparatus for supporting a drill, in particular for supporting overhead drilling, which allows the user of the drill to position and activate the drill in hard-to-reach places.
    BACKGROUND When repairing or building, it is often necessary to drill overhead or in other hard-to-reach places. When drilling above the head or in other hard-to-reach places, such as the false ceiling, the working position is particularly unergonomic when the required force must be applied through the drill. This is most evident when drilling a concrete suspended ceiling or subfloor. Therefore, there is a need for a device that allows the user to apply the necessary force to drill holes above the head or in other hard-to-reach places - without the user having to settle into and remain in non-ergonomic positions.
    SUMMARY OF THE INVENTION In accordance with the present invention, there is provided an apparatus for supporting and activating a drill. The apparatus comprises a longitudinal beam defining a longitudinal direction along its axis; - a drill support 102 for receiving and supporting the drill; an activation arrangement (e.g., handle + wire) for activating the drill; and a lever that pivots about the longitudinal bar. Turning the lever causes the drill support to move longitudinally with respect to the longitudinal beam; and the activating arrangement comprises a user engagement member disposed on the lever and configured such that user handling of the user engagement member activates the drill. Because the user-25 coupling member is positioned on top of the lever, the mechanical advantage provided by the lever to the user is improved while also allowing simple and easy control of the equipment and drill.
    S The user coupling part may comprise a rotating handle, and rotation of the rotating handle © activates the drill. The axis of rotation of the rotating handle may be parallel to the longitudinal axis r of the lever, and the axis of rotation of the rotating handle is preferably coaxial with the longitudinal axis & 30 of the lever.
    0 ON The user switching part is configured to activate the drill mechanically or electrically.
    = The activation arrangement comprises a wire connected at a first end to the engaging portion of user A and secured at a second end to a drill support, the cable configured to be> mounted on the drill trigger so that activating the user engaging portion tightens and depresses the trigger.
    The user coupling part is preferably located at the end of the lever remote from the longitudinal beam, which provides maximum mechanical advantage for applying drilling force. The apparatus may further comprise at least one support joint pivotally connected to the drilling support and the longitudinal beam. The support joint is positioned eccentrically with respect to the lever along the longitudinal axis of the longitudinal beam and extends parallel to the lever. The drilling support preferably comprises a chuck surface configured to receive a drill handle. The angle of the seat surface with respect to the longitudinal beam can advantageously be adjusted. The seat surface may comprise at least two height-adjustable supports, whereby each height of each height-adjustable support can be adjusted independently of each other. The length of the longitudinal beam can be adjusted, and the longitudinal beam may comprise a support portion at the end of the longitudinal beam remote from the drilling support. The drill can be a hand-held drill. Alternatively, the drill may have been integrated into the drilling support. The lever preferably comprises two lever arms arranged symmetrically on opposite sides of the longitudinal beam, and the articulation point between the lever and the longitudinal beam extends through both lever arms - and the longitudinal beam.
    BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the upper part of a drilling support according to the present invention. Figure 2A shows the drilling support in more detail. Figure 2B shows the drilling support from another angle.
    DETAILED DESCRIPTION Figure 1 illustrates a drilling support apparatus according to the present invention. The apparatus includes N longitudinal supports 101 extending along a longitudinal axis described by line LA extending longitudinally A25. The apparatus also includes drill support 102 for receiving and supporting drill 121. It should be noted that the drill 121 can be advantageously removed from the apparatus and that N is not in itself part of the apparatus itself. However, the drill may also be integrated into the drilling support equipment, = whereby the drilling support may be configured to receive and support the drill or its components in a housing which is an integral part of the drilling support. The lever 103 pivots about a longitudinal beam S30 at a point 111 and is connected from the first end 112 to the drill support 102. When the lever N pivots about the pivot point 111, the first end of the lever 112 connected to the drill support 102, S moves in the opposite direction to the other end of the lever 113. The movement of the lever 103 in itself causes the drilling support 102 to move along the longitudinal direction with respect to the longitudinal beam. The lever is preferably formed of two lever arms arranged symmetrically on opposite sides of the longitudinal beam so that the articulation point between the lever and the longitudinal beam extends through both lever arms and the longitudinal beam. The longitudinal beam 101 further preferably includes a ground support portion (not shown in the drawings) at the opposite end of the longitudinal beam 101 to the drilling support 102. In addition, the length of the longitudinal beam 101 can be advantageously adjusted, e.g. by a telescopic mechanism. The ground support member itself can be placed against the ground and the length of the longitudinal beam can be adjusted so that partial movement of lever 103 causes drill support member 102 and drill 121 to move toward the ceiling until the drill contacts the ceiling, while partial extension of lever 103 applies pressure to the ceiling.
    It will be appreciated that the movement of the drilling support is not parallel to the longitudinal axis, since the movement of the other end 112 draws an arc. However, at least some component of the movement of the drill support 102 is parallel to the longitudinal axis, so the movement is said to be parallel to the longitudinal axis. Preferably, the apparatus also includes a support member 105 that supports the drilling support and limits its range of motion to improve controllability of the drill position. As illustrated in Fig. 1, the support member 105 is a cross-member or two cross-members pivotally connected at one end to the drill support 102 and at the other end to the longitudinal beam 101. The transverse support axis running between the hinge support 102 and the longitudinal beam 101 is parallel to the hinge point 111 with the axis of the lever between the hinge point 112. The apparatus also includes an activation arrangement for remotely activating the drill. As illustrated in Figure 1, the activation arrangement includes a user engagement portion 104, a wire 106, and an activation portion
    107. The user engagement portion may be a rotating handle, such as those commonly found as a throttle in motorcycles, a compression lever, such as those commonly found as brake levers on bicycles and motorcycles, or any other suitable actuator. The movement of the user coupling part (e.g., twisting or squeezing) is transmitted to the activating part 107 by means of a wire 106, which activates the drill. This is shown and explained in more detail in connection with Figure 2. Alternatively, the user engagement portion may include a handle button, lever, switch, or other activation mechanism that the user can activate - during operation. Such a button or lever may have been placed in the system in such a way that it is easily reached by the user's thumb when the user grips the handle.
    S 30 The mechanical activation arrangement has been explained above, although the system may also operate by means of an electronic O activation arrangement. However, the mechanical activation arrangement is reliable and, combined with the z drill support, allows the use of essentially any type of hand-held drill bit in conjunction with the drilling support equipment.
    0) S It is significant that the user coupling part 104 is located at one end 113 of the lever 103. This N 35 - provides both the greatest mechanical advantage provided by the lever 103 to the user, which S allows a greater drilling force to be applied more easily and also allows simple and easy control of the equipment and drill, because the entire operating range, i.e. positioning the drill, moving the drill to position by moving lever 103, and activating the drill can be performed without the user changing the position of his hands.
    When the user engaging portion 104 is a rotating handle, the axis of rotation of the handle may be parallel to the longitudinal axis of the lever 103, i. with a shaft passing through the hinge point 111 and the other end 113. The axis of rotation of the handle is preferably coaxial with the longitudinal axis of the lever 103, which minimizes the application of translational forces to the apparatus due to the rotation of the handle and improves overall control and dexterity.
    Figures 2A and 2B show in more detail an embodiment of a drill support 102 in which the drill support is configured to receive a separate drill, e.g., a hand-held drill. Fig. 2A shows a side view of the drilling support 102 from the same perspective that can be seen in the figure
    1. The drilling support is shown without a drill in Figures 2A and 2B. The drilling support has a seat surface for receiving the drill handle. The seat surface can be adjusted to receive various drill handles and to adjust the angle of the handle with respect to the drill support 102 and the longitudinal beam 101. In the embodiment shown in Figures 2A and 2B, the drill support includes three fasteners 201, 202 and 203 for attaching the drill to the drill support. The seat surface consists of lower fastener portions 206 of each fastener 201, 202, 203. The height of each lower fastener portion 206 from the drill support can be adjusted by means of nuts 205 and bolts 204. The height of each lower fastener portion 206 can be adjusted independently of the other fasteners, allowing the shape and angle of the seat surface to be adjusted to receive a variety of drills.
    Fasteners 201 and 202 include upper fastener members used to secure the drill to the drill support. Fastener 203 does not have an upper fastener portion, but instead is configured for attachment points to wire 106. Fastener 203 is configured to be positioned on the drill handle at the same location as the drill trigger so that the lower fastener portion 206 of fastener 203 rests and 209. When the wire is pulled, i.e. due to the activation of the user coupling part, the wire itself tightens between the attachment points 208 and 209, which applies a force to the drill trigger, causing the drill to activate. The wire 106 may be a Bowden wire, with the outer sheath terminating at anchorage point 208, while the inner wire is anchored to the O anchorage point 209. The anchorage points 208 and 209 may also be considered part of the N30 activation arrangement.
    O As mentioned above, the activation of the drill can also be controlled electrically, in which case the wire 106 z and the attachment points 208, 209 may be missing.
    a AM As mentioned above, in another embodiment, the drill may have been integrated in the S drilling support. In this embodiment, the seat of the drill, e.g., the motor, and any N 35 control components may be included in a housing that is an integral part of the system, or may have been otherwise secured to the drill support 102.
