## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation-in-part of U.S. patent application Ser. No. 16/433,456, entitled “Ergonomic Attachment for a Ninety Degree Drill Assembly” and filed Jun. 6, 2019, now U.S. Pat. No. 11,633,846 issued on Apr. 25, 2023, the entire disclosure of which is incorporated by reference herein.


FIELD
This disclosure relates to an attachment for a hand tool and more particularly to an attachment to an angular drill assembly.
BACKGROUND
Angular drill assemblies are used in fabrication of many structures such as for example an aircraft. In angular drill assemblies, drill bits extend away from a main housing of the drill in angular relationship to the housing. The angular relationship includes, for example, ninety (90) degrees and forty-five (45) degrees. The operator of the ninety degree drill assembly will often utilize the palm of their hand to press against the housing of the drill assembly during the drilling operation. The palm of the operator's hand applies a force against the housing of the drill assembly which in turn transmits the force along the drill bit urging the drill bit in a direction of cutting a hole through a material. The operator in applying this force and particularly in a repetitive manner, can experience some discomfort in the use of the ninety degree drill assembly. Since gloves, for safety purposes are not always approved for use with a rotary tool or rotary device, there is a need to cushion the operator's hand from the force experienced by the operator's palm urging the housing of the ninety-degree drill assembly and in turn the drill bit in cutting the hole through material.
In addition, with the drill bit of a ninety-degree drill assembly extending ninety degrees from the main housing body of the drill assembly, wherein the main housing of the main body contains the motor of the drill assembly, the removal of the drill bit from a drilling position often involves the drill bit to be backed off in an opposing direction of that of the drilling direction. The backing off movement of the drill bit, out of an operational drilling position, can result in the housing of the ninety-degree drill assembly colliding with another surface of the structure being fabricated, particularly when operating in confined locations. The surface impacted by the drill assembly can result in the surface impacted being marred or damaged resulting in a need to repair that surface.
The housing of the ninety-degree drill assembly is constructed of a hard material such as metal. Movement of the drilling assembly within the structure being fabricated can result in the housing of the drill assembly colliding with the structure being fabricated or even by way of dropping the drilling assembly within the structure resulting in marring or damaging a surface of the structure being fabricated. Should the surface impacted include a finished surface, the finished surface will need to be repaired and refinished. As a result, there is also a need to protect surfaces of the structure being fabricated from collisions with respect to the housing of the ninety degree drilling assembly so as to reduce the occurrence of marring and/or damage to a surface of the structure being fabricated.
In other angular drill assemblies, such as a forty five degree drill assembly, the drill bit extends angularly from the housing in a forty five degree angle. The operator has difficulty, with the drill assembly in operation, in urging the drill bit in a direction perpendicular to the surface being drilled. This is particularly challenging with operating the drill assembly within confined locations.
The operator in utilizing a forty five degree drill assembly similarly applies a force in urging the drill bit during operation with a palm or other portions of the hand. This urging, particularly in a repetitive manner, can cause the operator to experience some discomfort in the use of the forty five degree drill assembly. Since gloves, for safety purposes, as mentioned earlier, are not always approved for use with a rotary tool or rotary device, as a result, there is a need to cushion the operator's hand in using the drill assembly.
As earlier mentioned with respect to the ninety degree drilling assembly, similar protection is needed to protect surfaces of the structure being fabricated from impacts incurred by the drilling assembly. These impacts, as earlier mentioned, can arise from backing out of the drill bit from a drilling operation, the drilling assembly being moved around within the structure being fabricated and from the drill assembly being dropped within the structure being fabricated. As a result, there is a similar need with respect to the forty five degree drill assembly to reduce the occurrence of damaging or marring surfaces in the structure being fabricated.

DESCRIPTION
Examples of removable attachment assemblies for an angular drill assembly will be discussed herein. Angular drill assemblies have an angular relationship between a drill bit and a main housing of the angular drill assembly. The amount of angular relationship can vary. In this discussion a first example of a removable attachment assembly 10 will be associated with a ninety degree drill assembly 12, as seen in FIGS. 1-8. A second example of a removable attachment assembly 96 will be associated with a forty five degree drill assembly 98, as seen in FIGS. 10-12.
In referring to FIGS. 1-8 removable attachment assembly 10 for a ninety degree drill assembly 12 includes base member 14 and securement assembly 16 secured to base member 14 for releasably securing base member 14 to housing 18 of ninety degree drill assembly 12, wherein drill bit 42 extends away from housing 18 in a ninety-degree angle represented as angle “A” as seen in FIG. 8. Releasable securement of base member 14 to housing 18 includes attachment and removal of base member 14 with respect to housing 18 without need of a tool. Removable attachment assembly 10 further includes cushion member 20 secured to base member 14.
Base member 14 facilitates alignment and mounting of removable attachment assembly 10 onto ninety degree drill assembly 12 such that cushion member 20, with ninety degree drill assembly 12 in operation, is positioned to contact hand 22 of operator, as seen in FIG. 1. Additionally, securement assembly 16 is secured to base member 14 which secures removable attachment assembly 10 to housing 18 of ninety degree drill assembly 12.
Base member 14 is constructed of a strong material such as one of a thermoplastic, thermoset or metal. In facilitating alignment and mounting base member 14 of removable attachment assembly 10 onto ninety degree drill assembly 12, base member defines concave surface 24, as seen in FIG. 4, which faces in direction D away from cushion member 20 and which extends in direction D1 along length L of base member 14. Concave surface 24 is configured in this example to complement the shape of housing 18 to which base member 14 contacts. In this example, housing 18, which includes drive shaft portion 26 of housing 18, has a curved surface 28, as seen in FIG. 3, to which concave surface 24 has a complementary configuration for mounting of removable attachment assembly 10 so as to have a stable interface between housing 18 and base member 14. With portion of drive shaft portion 26 of housing 18, in this example, positioned within concave surface 24, base member 14 is positioned in alignment with portion of drive shaft portion 26 of housing 18.
In referring to FIG. 4, base member 14 further defines first wall portion 30 and second wall portion 32 which are spaced apart from one another. First wall portion 30 and second wall portion 32 each extend in the direction D away from cushion member 20 and first wall portion 30 and second wall portion 32 each extend in the direction D1 along length L of base member 14. Base member 14 further includes defining third wall portion 34 which connects together first wall portion 30 and second wall portion 32. In this example, third wall portion 34 extends in curvilinear direction 36. In this example, as shown in FIG. 4, first, second and third wall portions 30, 32 and 34 configure a receptacle 38 for receiving, aligning and mounting base member 14 to housing 18 of ninety degree drill assembly 12, and more particularly in this example, to mounting to main portion or drive shaft portion 26 of housing 18 and to ninety degree offset portion 40 of housing 18, as seen in FIG. 3.
First wall portion 30 and second wall portion 32, which are spaced apart from one another, receive a main or drive shaft portion 26 of housing 18, as seen in FIGS. 1-3. Third wall portion 34 encloses a portion of ninety degree off set portion 40 of housing 18 with base member 14 mounted onto housing 18 of ninety degree drill assembly 12. With base member 14 mounted to housing 18 of ninety degree drill assembly 12, cushion member 20 is positioned between hand 22 of the operator and housing 18, as seen in FIG. 1, for drilling operations. In drilling operations, hand 22 of the operator, in this example, pushes against cushion member 20 and base member 14 in turn pushes against housing 18 urging drill bit 42 in direction D2, as seen in FIGS. 3, 6 and 8, in cutting through material (not shown) in forming a hole (not shown) in the material (not shown).
In referring to FIG. 3, base member 14 includes projection 44, which extends in direction D3 away from securement assembly 16. Projection 44, in this example, defines rim 46, which extends along perimeter 47 of the projection 44. First tab 48 of projection 44 extends away from rim 46 on a first side 50 of projection 44 and second tab 52 of projection 44 extends away from rim 46 on second opposing side 54 of projection 44. Cushion member 20 defines first recess 56 within cushion member 20 for receiving projection 44 within cushion member 20 and defines second recess 58 within first recess 56 as seen in FIGS. 3 and 7 for receiving first tab 48 and second tab 52. With positioning projection 44 within the first recess 56 first tab 48 is positioned within second recess 58 and second tab 52 is positioned within second recess 58, an interference fit is formed between first tab 48 and second recess 58 and second tab 52 and second recess 58. Second recess 58 is positioned spaced apart from bottom surface 60 of cushion member 20, wherein with first and second tabs 48, 52 positioned within second recess 58 bottom surface 60 abuts support surface 62 defined by base member 14.
Cushion member 20 is constructed of resilient material such as for example thermoplastic polyurethane material. This resilient material will maintain the interference fit of first tab 48 with second recess 58 and of second tab 52 with second recess 58. This material will provide cushion member 20 firm securement to base member 14 and allow, as needed, the operator to remove cushion member 20 from projection 44 of base member 14 without incurring damage to either cushion member 20 or base member 14. In securing cushion member 20 to projection 44, operator positions projection 44 within first recess 56 and pushes cushion member 20 and projection 44 together such that at least one of first tab 48 and second tab 52 flexes the resilient material of cushion member 20 at first portion 53 and/or second portion 55 of cushion member 20, as seen in FIG. 7, wherein first portion 53 and second portion 55 are each adjacent to second recess 58. Flexing of the resilient material in at least one of first and second portions 53, 55 permits at least one of first and second tabs 48, 52 to be positioned within second recess 58, as seen in FIG. 7 creating an interference fit. In removing cushion member 20 from projection 44, operator pulls on cushion member 20 such that at least one of first tab 48 and second tab 52 flex the resilient material of at least one of first and second portions 53, 55 of cushion member 20 adjacent second recess 58 permitting first and second tabs 48, 52 to be removed from second recess 58 overcoming the interference fit and thereafter removed from first recess 56.
In referring to FIG. 5, cushion member 20 includes first width dimension W1 and second width dimension W2 which each extends in transverse direction DT relative to length L1 of cushion member 20 and are spaced apart along length L1 of cushion member 20 from one another. Third width dimension W3 of cushion member 20 extends in transverse direction DT relative to length L1 of cushion member 20 and is positioned spaced apart from and in between the first width dimension W1 of cushion member 20 and second width dimension W2 of cushion member 20 wherein third width dimension W3 is less than each of first and second width dimensions W1, W2. This varying width configuration of cushion member 20 provides for a lesser width dimension in a central portion 61 of cushion member 20 as seen in FIG. 5. This reduction of width dimension in central portion 61 of cushion member 20 provides operator ease in straddling, for example, a thumb and an index finger of an operator on either side of cushion member 20 in order to hold a drill guide (not shown) which may be used for a drilling operation with ninety degree drill assembly 12. The narrowed central portion 61 of cushion member 20 permits the operator to comfortably hold a drill guide with for example a thumb and an index finger straddling cushion member 20 at central portion 61 and at the same time use a remainder portion of the same hand of the operator to apply a pushing force against cushion member 20 during the drilling operation.
Securement assembly 16, as seen in FIGS. 4 and 7, in this example, includes first arm member 64 and second arm member 66, which extend in direction D away from cushion member 20. First arm member 64 has a first curvilinear configuration 68 and the second arm member 66 has a second curvilinear configuration 70. First arm member 64 and second arm member 66, in this example, are each constructed of one of a thermoplastic, thermoset or metal material, which provides resilience to first and second arm members 64, 66 such that first and second arm members 64, 66 can move in and out of an interference fit with housing 18, as described below.
With first and second arm members 64, 66 not engaged to housing 18 of ninety degree drill assembly 12, as shown in FIG. 4 and as shown in phantom in FIG. 7, first free end 72 of first arm member 64 and second free end 74 of second arm member 66 are positioned spaced apart first distance D4, as seen in FIG. 7. With insertion of the housing 18 between first arm member 64 and second arm member 66, first free end (designated as) 72′ and second free end (designated as) 74′ are then spaced apart a second distance D5, which is a greater distance than first distance D4, which results in first and second arm members 64, 66 exerting a compressive force F onto housing 18 providing an interference fit between housing 18 and first and second arm members 64, 66.
In referring to FIG. 4, base member 14 defines first opening 76 positioned on first side 78 of base member 14 and second opening 80 positioned on opposing second side 82 of base member 14. Base member 14 defines slot 84 which extends through base member 14 from first opening 76 to second opening 80 such that slot 84 is accessible from first opening 76 and from second opening 80. Slot 84 extends, in this example, in direction D6 transverse to length L of base member 14 as seen in FIG. 4. Slot 84, as will be discussed herein, is utilized in conjunction with zip tie member 90, as seen in FIG. 6, for additional securement of base member 14 to housing 18. Additionally, slot 84 can facilitate securement of lanyard member 92, as seen in FIG. 8, for preventing removal attachment assembly 10 from being separated from ninety degree drill assembly 12 and become unwanted debris within the structure being fabricated such as an aircraft.
In referring to FIG. 9, method 86 for installing removable attachment assembly 10 to a ninety degree drill assembly 12 includes step 88 of securing base member 14 to housing 18 of the ninety degree drill assembly 12 with securement assembly 16. Securement assembly 16 is secured to base member 14. Cushion member 20 is secured to base member 14 such that cushion member 20 has surface 21 which faces direction D7 away from housing 18, as seen in FIG. 7. With surface 21 of cushion member 20 positioned facing in direction D7 away from housing 18, cushion member 20 provides operator's hand cushioning, with operator's hand 22 pushing against surface 21 of cushion member 20 and operator urging drill bit 42 through material of hole being drilled during operation of ninety degree drill assembly 12.
Cushion member 20 can be easily replaced by the operator with base member 14 having projection 44 which extends in direction D3 away from securement assembly 16, as seen in FIG. 3. Projection 44, in this example as described above, defines rim 46, which extends along perimeter 47 of the projection 44. First tab 48 of projection 44 extends away from rim 46 on a first side 50 of projection 44 and second tab 52 of projection 44 extends away from rim 46 on second opposing side 54 of projection 44. Cushion member 20 defines first recess 56 within the cushion member for receiving projection 44 and defines second recess 58 for receiving first tab 48 and second tab 52, as seen in FIG. 7, such that with positioning projection 44 within the first recess 56, first tab 48 is positioned in second recess 58 and second tab 52 is positioned in second recess 58 forming an interference fit between first tab 48 and second recess 58 and second tab 52 and second recess 58. Second recess 58 is positioned spaced apart from bottom surface 60 of cushion member 20, wherein with first and second tabs 48, 52 positioned within second recess 58 bottom surface 60 abuts support surface 62 defined by base member 14.
Cushion member 20 is constructed of resilient material such as for example thermoplastic polyurethane material. This resilient material will maintain the interference fit of first tab 48 with second recess 58 and of second tab 52 with second recess 58. This material will provide cushion member 20 firm securement to base member 14 and will allow, as needed, the operator to remove cushion member 20 from projection 44 of base member 14 without incurring damage to either cushion member 20 or base member 14. As mentioned earlier, in securing cushion member 20 to projection 44, operator positions projection 44 within first recess 56 and pushes cushion member 20 and projection 44 together such that at least one of first tab 48 and second tab 52 flexes the resilient material of cushion member 20 at first portion 53 and/or second portion 55 of cushion member 20, as seen in FIG. 7, wherein first portion 53 and second portion 55 are each adjacent to second recess 58. Flexing of the resilient material in at least one of first and second portions 53, 55 permits at least one of first and second tabs 48, 52 to be positioned within second recess 58, as seen in FIG. 7, creating an interference fit. In removing cushion member 20 from projection 44, operator pulls on cushion member 20 such that at least one of first tab 48 and second tab 52 flex the at least one of first portion and second portion 53, 55 of the resilient material of cushion member 20 adjacent second recess 58 permitting first and second tabs 48, 52 to be removed from second recess 58 overcoming the interference fit and thereafter removed from first recess 56.
