Description

Guiding tool for angled installation of fasteners and combination method thereof

The present disclosure generally relates to the field of tools for guiding the installation of fasteners.

In building construction and especially in wood construction, it is common to use fasteners such as screws or nails to fix a construction element made of wood or composite materials, such as slats or planks, to another similar construction element . The fixing of the two construction elements is usually done by positioning the two construction elements on top of each other and driving the fasteners and the surfaces of the two construction elements orthogonally into both of them. At the same time, the practice of placing the fasteners orthogonally on the surface does have disadvantages. In addition to being aesthetically unpleasant, it can be dangerous in certain situations. For example, when installing a deck, fasteners whose top is not completely flush with the deck surface can cause the feet to get stuck on it.

One solution to this problem is to install the fastener on the side of the board instead of on the top by driving the fastener into the construction material at an angle. Although this solves the problem, installing fasteners in this way is a more challenging process.

There are tools to help guide the installation of these fasteners to ease the difficulty of installing these fasteners at an angle. These tools usually include some form of orifice with an opening at one end for inserting a fastener and an opening that can be placed on the side of the structural member.

What's more complicated is that materials behave differently according to different environmental conditions, which change with time. For example, a wooden material used in the construction of outdoor decks can shrink and expand by a few millimeters in an environment where the temperature and humidity change significantly with the seasons, and when different types of wood are used, the size change may only be the above change a small part of. Then, the space between the installed structural members becomes important to avoid damage to the material. Similarly, the angle of the fastener and the distance between the fastener and the edge of the structural member need to be carefully selected to avoid cracking or swelling of the material.

Some tools used to guide fasteners at an angle allow one component to be replaced to suit different working conditions. In these cases, the construction member can be installed by measuring where each fastener should be placed as needed to ensure that the construction material is not damaged and the fasteners are aligned with each other before engaging the guide tool. This is a functional solution, but it is cumbersome, requiring the operator to use the tool in the same location every time, and the solution is time-consuming, so there is room for improvement.

The purpose of the present invention is to alleviate at least part of the above-mentioned problems. This is achieved by providing a more versatile and customizable tool and method for guiding the fastener into the side of the structural member at a desired angle.

According to the present disclosure, one embodiment of the present invention is a guiding tool for guiding a fastener used to fasten a first structural member to a second structural member, the guiding tool includes:

A main body, the main body includes a support, and the support is a part of the guiding tool to be located on the top surface of the first structural member;

A first spacer having a lip protruding from the support of the guide tool substantially perpendicular to the support;

A second spacer having a lip that protrudes from the support substantially perpendicular to the support and substantially parallel to the lip of the first spacer;

A device for changing the distance between the first spacer and the second spacer;

An orifice in each of the first spacer and the second spacer, the orifice extending at an angle less than perpendicular to the main body of the guide tool;

Wherein the first spacer and the second spacer are both releasably connected to the main body of the guiding tool.

An example of a fastener is a screw; other fasteners consistent with the spirit of the present invention can be used. Examples of the first structural member and the second structural member are wood planks and wooden joists; however, other structural members may be used, for example, the other structural members may be composed of other materials such as composite materials. Thus, the tool can be used, for example, to guide screws through a piece of wood into a joist, wherein the wood is on top of the joist, whereby they are fastened to each other.

By placing the support in contact with the top surface of the first structural member, the guiding tool can be placed on the top surface. In this placement, the lips of the first and second spacers will extend downward on each side of the first structural member. The lip of the spacer can be engaged with the side surface of the first structural member, whereby the position of the guiding tool is fixed. The lips of the first spacer and the second spacer help to evenly space the adjacent first members.

The adjustable distance between the first spacer and the second spacer helps to enable the guiding tool to be used with construction members of different sizes. The size of the structural member may vary due to design, such as a wide or narrow wood board, or the size of the structural member may vary due to a slight change in the nominal width of the structural member.

The fastener can be placed in the aperture, thereby guiding the fastener to the side of the first structural member, where the fastener can be installed at a desired angle. Fixing the first structural member on the side makes the fastener less visible, which can be more aesthetically pleasing. In addition, if the fastener is instead placed orthogonally in the top surface of the first structural member, it is likely that the fastener is not completely flush with the top surface, and thus people or objects may be caught on the fastener and suffer. To destruction. The aperture ensures that the fastener remains stable at the desired angle and height on the side of the first structural member, which is difficult to achieve without a guiding tool.

The first spacer and the second spacer are releasable so that the spacers can be exchanged with variants having different physical characteristics. The thickness of the lip of the spacer is a feature that can be changed. The angle of the orifice of the spacer is a feature that can be changed. The thickness of the spacer lip determines the distance between adjacent structural members. Therefore, being able to choose different thicknesses of lips allows the same tools to be used when working with different materials such as different types of wood, which will expand more or less when environmental conditions change. This feature is also important when working in different environments where temperature and humidity fluctuations vary to varying degrees.

Both spacers can be replaced, ensuring that they can meet the requirements of working conditions. If only one spacer can be replaced, the user may need to turn the guide tool when driving the second fastener into the structural member, or may face the use of a guide tool, fastener, fixing tool, or structural member Risk of damaging guide tools, fasteners, fixing tools or structural members due to a poor combination on the side. For example, the operator may wish to use a small diameter fastener; if only one spacer can be replaced, the other spacer will have an excessively large aperture, whereby the fastener may become loose and angled within the aperture. In addition, having the option of ensuring that the spacer has the same characteristics gives the operator more freedom in the working direction and how to position the guide tool. In cases where the operator would benefit from spacers with different characteristics or if one spacer could be better omitted, the option of swapping the two spacers also allows for further customization. For example, if the first structural members are to be placed with a minimum gap between them, the movable spacers can be omitted, while the fixed spacers can be maintained to aid the placement of the structural members and the angular guidance of the fasteners.

In one embodiment, the first spacer and the second spacer are releasably attached to the remaining part of the guiding tool by a device including a T-shaped track.

By the T-shaped rail connection, it can be understood that one element has a protrusion with a T-shaped cross-sectional profile, that is, one part extends perpendicular to the element, and the other part is perpendicular to the first part at the distal end and in its Extending on opposite sides, the extensions may have the same length or different lengths. The other elements to be connected have grooves with corresponding cross-sectional profiles. Therefore, the connection can be made by placing the end of the protrusion and the end of the groove adjacent to each other and sliding one into the other longitudinally. The T-shaped rail connection ensures that the spacer can be installed in the remaining part of the guide tool with the necessary tolerances. The T-shaped rail connection further ensures that the spacer will be installed at the correct angle and that the spacer is easily aligned to the part of the guide tool to which it is attached. In one aspect, the spacer may have an additional connecting device besides the T-shaped rail connection, and the connecting device fixes the relative position of the spacer so that the spacer cannot further translate along the T-shaped rail when a force is applied during operation.

In one embodiment, the position of the first spacer is adjustable, and the position of the second spacer is fixed, so their relative distance is variable.

As mentioned earlier, the variable distance between the first spacer and the second spacer has several benefits. That is, the first spacer is movable while the second spacer is fixed allowing the benefits to be maintained, while also providing the guiding tool with a rigid contact point on the side of the first structural member. During use, the operator may want to apply a force to the first structural member by the guide tool to move the first structural member and keep it in place. If both spacers are movable, the application of the force may cause the spacer to move instead of moving the first structural member as expected. Fixing the second spacer allows the operator to maintain the selected distance between the first spacer and the second spacer, while allowing the user to apply force by a guide tool and use the second spacer as a contact point to use the The force is transmitted from the guiding tool to the first structural member to move the first structural member.

In an embodiment of the present invention, a device for adjusting the position of the first spacer relative to the second spacer includes a spring and a trigger.

The trigger is connected to the movable spacer such that pulling the trigger will increase the distance between the first spacer and the second spacer. Therefore, the operator can directly control when to increase the distance between the spacers and how much the distance between the spacers increases. The spring will provide a constant force that pulls the first spacer and the second spacer towards each other. Therefore, by pulling the trigger, the operator overcomes the spring force to work. When the guide tool is placed in the desired position in contact with the top surface of the first structural member, by simply letting go of the trigger and does not provide an external action against the spring force, the lip of the spacer will interact with the first The sides of a structural member are joined. The spring ensures continuous engagement between the guiding tool and the first structural member until the operator wishes to release the spring, at which point it can be overcome simply by pulling the trigger again or by other means such as tilting or lifting the guiding tool Spring force work to complete.

In an embodiment of the present invention, a device for adjusting the position of the first spacer relative to the second spacer includes a first track and a second track, and the first track and the second track may be The different positions are fixed to each other.

The first spacer and the second spacer are connected by the first rail and the second rail whose relative position can be adjusted by translation, which allows semi-permanent adjustment of the distance between the first spacer and the second spacer . If the guide tool is to be used with various types of first structural members that can have different nominal sizes, for example, the guide tool is used in two different environments where a larger board is used in one place and the other is not used Use, then this is beneficial. Then, the distance between the first spacer and the second spacer can be set by adjusting the positions of the first rail and the second rail to be suitable for use with the related first structural member. Once the proper positions of the first track and the second track are selected, they are fixed to each other. This allows the same guiding tool to be used in various situations, for example if the first structural member is particularly wide, instead of having to replace the guiding tool with a different guiding tool.

In an embodiment of the present invention, the angle of the aperture of the spacer relative to the main body is in the range of 35-70 degrees.

The angle at which the fastener can be placed is limited by the distance between the first structural member to be fixed and the already fixed structural member or from the stopping point to which the first structural member is to be placed adjacent to it. Furthermore, choosing the correct angle ensures that the first structural member is firmly secured to the second structural member. Choosing an angle that is too small will cause the fastener to pass close to the lower edge of the side of the first structural member, which may cause damage to the first structural member. For example, if the first structural member is made of wood, such damage may crack parts of the first structural member. Such damage will make the fastening of the first structural member and the second structural member less firm. If the fastener is placed at an excessively large angle, the fastener will have a long travel distance in the first structural member. Therefore, the fastener needs to be longer than necessary when it is placed at a steeper angle, otherwise the fastener will not be able to reach the second structural member and cannot help tighten the first structural member and the second structural member. solid. In addition, placing such relatively long fasteners at a high angle will lead to the following risk: two fasteners placed directly across each other on either side of the first structural member need to be driven to The first structural member. This in turn will result in the two fasteners either being unable to be placed or at least risking damage to the fasteners when the fasteners collide in the first structural member.

In an embodiment of the present invention, the spacer includes an outlet for material shavings, which can be released from the structural member during placement of the fastener.

When the fastener is driven into the structural member, a part of the material constituting the structural member will be released as shavings to make room for the fastener. If the shavings are driven into an orifice without an outlet, this may cause blockage of the orifice, resulting in the need to increase the driving force or cause the fastener to tilt. The outlet alleviates these problems because the shavings can exit the orifice near the structural member without passing through the orifice around the fastener.

In an embodiment of the present invention, the guiding tool includes a handle.

The presence of the handle allows the operator to position and move the guiding tool more easily as needed. The handle provides leverage and a firm grip on the guiding tool, making it easier for the operator to handle the first structural members, even if they are heavy or long.

In an embodiment, the handle protrudes from the main body and is closer to the second spacer than the first spacer.

If the second spacer is fixed while the first spacer is movable, placing a handle close to the second spacer can ensure that the operator transfers the force required to move and position the first structural member from the guide tool to the The vicinity of the point of the first structural member easily applies force to the structural member. During use, the operator preferably pushes the guiding tool forward at the same time behind the guiding tool to place the first structural member adjacent to the fixed structural member or stopping point. Therefore, positioning the handle close to the second spacer means that the handle will also be close to the operator; therefore, the operator can use his own weight to increase the pushing of the guiding tool, thereby reducing the required muscle power. Allows the operator to use the leverage of his own weight to make work easier and reduce the risk of injury due to excessive force.

In an embodiment, the handle has a curvature from a position where the handle is attached to the main body toward the first spacer, whereby the handle extends above the main body of the guide tool.

This curvature of the handle ensures that under the most common working conditions, the operator will have enough gripping surface to apply force when pressing the first structural member into place adjacent to the fixed structural member or stopping point. In addition, the curvature of the handle ensures that if the operator needs to use the guiding tool in a less than ideal position, the necessary pressure can still be maintained to keep the first structural member in the desired position until the fastener has been placed.

In one embodiment, the width of the handle of the guiding tool is at least 60% of the width of the support of the guiding tool.

The size of the handle helps the operator have good working conditions, thereby reducing the risk of excessive force and the resulting work-related injuries. A large force-applied area increases the area of the operator's hand, and the increased area experiences an equal force applied to the area, so the force per unit area is reduced and the risk of damage is also reduced.

Another aspect of the present invention is an embodiment of the guide tool, wherein the distance from the center point of the orifice to the first side of the support of the guide tool is at least 26 mm.

Making this distance an integral part of the design enables operators to use it as a measuring device while working. The operator will know that if the edge of the support of the guide tool is flush with the end of the first structural member, the fastener will be at a distance from the first structural member if the structural member is made of common wood. The recommended minimum distance of the end is driven into the wood. This allows the operator to dispense with the measuring step, whereby the process of fastening the structural member becomes more efficient.

In an embodiment of the present invention, the center point of the orifice is approximately equidistant from the first side and the second side of the support of the guiding tool.

This placement ensures that the benefit of the known minimum distance between the edge of the support of the guide tool and the place where the fastener is placed as described above persists regardless of the working direction or which end of the plate the fastener is placed near.

One embodiment of the present invention is to use the disclosed guiding tool to guide a fastener to fasten the first structural member to the second structural member.

US 8925644 B2 relates to a fastener installation tool, which includes a guide that guides the fastener into the side of a workpiece at an angle. The guide may define an angled orifice including a fastener inlet and a fastener outlet, the orifice being adapted to be positioned proximate the workpiece. The guide may include a material discharge part between the openings, by which material generated from the workpiece may be discharged from the angled orifice to prevent the material from adhering to the fastener. The tool may include a clamp assembly that clamps opposite sides of the workpiece to accurately align the angled apertures and stably maintain the apertures when the fastener is being installed in the side surface. One of the two parts of the jig assembly of the tool can be replaced.

Hereinafter, the present invention will be described in detail through the embodiments of the present invention, and the embodiments should not be considered as limiting the scope of the present invention.

Figure 1 shows an embodiment of the guiding tool 100 according to the present invention in an application state where the guiding tool 100 is engaged with the first structural member 10, wherein the first structural member 10 is fixed to the second structural member 20 . The guiding tool 100 is placed with its support 101 in contact with the top side of the first structural member 11. The guide tool is clamped to the first structural member 10 by the movable first spacer 150 (not visible in the perspective view shown) and the fixed second spacer 150', the spacers 150, 150' Both include lips 151, 151 ′, which protrude substantially perpendicular to the support 101 of the guiding tool 100. The first spacer 150 and the second spacer 150' are engaged with the opposite sides 12, 12' of the first structural member 10.

During use, the operator will apply pressure to the handle 120 to position the first structural member 10 adjacent to the fixed structural member 10' or adjacent to another stopping point where the first structural member 10 is to be installed adjacently. The thickness of the lip 151 on the first spacer 150 protruding near the front end 102 of the guide tool determines the distance between the first structural member 10 and the fixed structural member 10'.

Once the first structural member 10 has been placed as described, the first structural member 10 can be fixed to the second structural member 20 by the fastener 30. The fastener 30 is placed in the aperture 155 in the spacer 150. The aperture 155 is arranged such that the fastener 30 will exit the aperture 155 immediately adjacent to the side of the first structural member 12. The fastener will be guided at an angle so that the fastener 30 will enter the side of the first structural member 12 at that angle. When the fastener 30 is driven forward by the first structural member 10, the fastener 30 leaves the first structural member 10 by the bottom side 11' before being driven to the top surface 21 of the second structural member, thereby The first structural member 10 is fixed to the second structural member 20.

In a preferred embodiment of the present invention, the aperture 155 is configured such that the fastener 30 will be driven into the first structural member 10 at an angle that is not orthogonal to the side 12 of the structural member, and the angle (not (Shown) is chosen to ensure that the fastener will enter the first structural member 10 through the side 12 and exit through the bottom surface 11'. In an embodiment of the invention, the angle of entry will be between 35 degrees and 70 degrees. The possible angles depend on the size of the fastener and the space between the first structural member 10 and the fixed structural member 10' or stop point. In a more preferred embodiment, the orifice is configured so that the angle is between 52 degrees and 55 degrees.

FIG. 2 shows a side view of the guiding tool 100 engaged with the first structural member 10. The guiding tool includes a main body 105 with a handle 120, which may be integrated in the main body 105 or attached to the main body 105 by a separate fastening device. The handle 120 has a concave curvature relative to the first spacer 150. The handle 120 has a free end 121 closest to the front end of the guide tool 102. In addition, in the embodiment of the guiding tool 100, the handle 120 includes a section with a gripping material 123, which has a higher friction force than the rest of the handle 120, so as to reduce the guiding tool 100 during use. The risk of sliding. The curvature of the handle 120 is formed to provide the user with a firm grip on the guiding tool 100, and the curvature of the handle 10 can be adjusted to adapt to the angle at which the work is completed. In addition, the handle 120 is directed forward, so that when the first structural member 10 is installed adjacent to the fixed structural member 10' or other stopping points, the user naturally applies force forward as needed.

The guiding tool 100 further includes a movable first spacer 150 and a fixed position second spacer 150' respectively installed at the front end 102 and the rear end 103 of the main body 105 of the guiding tool. The spacers 150 each include an orifice 155 for guiding the fastener 30 directly at the first structural member 12 at a desired angle once the guiding tool 100 is installed on the first structural member 10 The desired end position at the surface of the side. The spacer 150 further includes a lip 151 extending downward from the support 101 of the guiding tool 100. During operation, the lip 151 will be positioned on the side of the first structural member 12, 12'. The thickness of the lips 151, 151' of the spacer 150, 150' determines the distance between the installed first structural member 10 and the adjacent previously fixed structural member 10' or stop point.

In addition, the guiding tool 100 includes a trigger 130. The trigger 130 has an arm 131 that is placed to extend between the main body 105 of the guide tool and the handle 120. As shown in the figure, the arm 131 may be configured to have a length similar to that of the handle 120. In different embodiments of the present invention, the trigger 130 can be configured such that the arm 131 is significantly shorter than the handle, for example, one third of the length of the handle 120. During operation, the trigger arm 131 can be pulled toward the handle 120 (the direction of movement shown by arrow B). The trigger 130 is mechanically connected to the first spacer 150 such that pulling the trigger arm 131 toward the handle 120 causes the first spacer 150 to move away from the second spacer 150' (the direction of movement shown by arrow C) mobile. The trigger 130 may further include a tap 132 that extends upward from the side of the trigger 130 away from the main body 105 of the guide tool and is close to the free end of the trigger arm 131. When the trigger 130 is pulled during operation, the contact 132 will be the point of contact between the trigger 130 and the handle 120. Therefore, the contact 132 serves as a stopper to ensure the space between the trigger 130 and the handle 120 at all stages of operation, thereby reducing the user’s fingers or loose objects from being clamped between the trigger 130 and the handle 120. risk.

In order to mount the guiding tool 100 on the first structural member 10, the trigger 130 is pulled toward the handle 120, whereby the first spacer 150 moves away from the second spacer 150'. Then, the guiding tool 100 is placed on the top surface 11 of the first structural member 10 with its seat 101 surface. Then, the trigger 130 can be released, and the first spacer 150 moves back toward the second spacer 150' due to the spring tension, therefore, the lips 151, 151' of the first spacer 150 and the second spacer 150' Clamped to the sides 12, 12' of the first structural member 10. Once the guiding tool 100 is installed on the first structural member 10, the first structural member 10 can be adjacent to the fixed structural member 10' or the second structural member 20 to which the first structural member 10 will be fixed. The stop point on the top is positioned.

Once the guiding tool 100 has been installed on the first structural member 10 and the first structural member 10 is positioned as intended, the fastener 30 can be placed in the apertures 155, 155' of the spacer 150, 150'. The drill bit 40 may be mechanically connected to the fastener 30 at one end and to a device for driving the fastener 30 forward, such as a drill or a screwdriver (not shown), at the other end. Using the driving device, the fastener 30 can be driven into the first structural member 10 and the second structural member 20 through the aperture 155 (not visible from this angle). The aperture 155 guides the fastener 30 to have a desired angle, and it restricts undesired movement of the fastener 30 such as swinging, which may result in less than ideal placement of the fastener 30 or to the first structural member 10 or damage to the second structural member 20.

In a preferred method of operation, the fastener 30 placed in the second spacer 150' is first fixed, and the operator simultaneously applies pressure to the handle 120, so that the first structural member 10 remains adjacent when being fixed. The fixed structural member 10' or the desired position of the stopping point. Subsequently, the second fastener 30' may be fastened in the first spacer 150 to more completely fix the first structural member 10 to the second structural member 20. While placing the second fastener 30', the operator does not need to apply considerable pressure to the guiding tool 100 as when placing the first fastener 30. Placing the first spacer 150 and the second spacer 150' at each end of the guide tool 100 allows the first fastener 30 and the second fastener 30' to be placed without having to move the guide tool 100, thereby speeding up the work process, and It is easy to achieve an aesthetically pleasing result in which the fasteners 30, 30' are placed directly opposite each other.

Fig. 3 shows a cross section of the guiding tool 100 engaged with the first structural member 10 viewed from the side according to an embodiment of the present invention. The first spacer 150 and the second spacer 150' are releasably mounted on the first block 170 and the second block 170'. The first block 170 may be releasably mounted to the first rail 190, or it may be integrated in the rail 190. The second block 170' may be releasably mounted to the main body 105 of the guiding tool, or it may be directly integrated into the main body 105 of the guiding tool. The angle and position of the fastener 30 are controlled by the aperture 155 in the spacer 150. As shown, there is a fastener 30 in another aperture 155', the diameter of which is intended to be very close to the diameter of the aperture 155, so that any other than the longitudinal direction along the aperture 155 Movement in the direction is minimized. The fastener 30 exits the aperture 155 so that the tip of the fastener 30 is positioned next to the first structural member 10 to minimize the risk of the fastener 30 gripping the material of the first structural member 10 at an angle different from the aperture 155 . The thickness (indicated by arrow T) of the lip 151 of the spacer 150 determines the distance between the first structural members 10.

The cross-sectional view shows that the mechanical connection between the trigger 130 and the first spacer 150 is a spring 140. The spring 140 exerts a force (the force shown by the arrow D) that pulls the first spacer 150 and the second spacer 150' together. The trigger 130 is attached to the main body 105 of the guide tool by the first pin 135. Pulling the arm 131 of the trigger causes the trigger 130 to rotate around the pivot point at the center of the first pin 135. The trigger includes a base 133. In this embodiment of the present invention, the base 133 is shaped as an upper base 133' and a lower base 133". Each base has a substantially circular profile. The upper base 133' has a lower base than the lower base 133. ''A larger radius. When the trigger 130 is at rest, the edge of the lower base 133'' is stopped by the second block 170', preventing the trigger 130 from extending all the way down and on the top of the main body 105 of the guiding tool. Therefore, the trigger position between the main body 105 of the guide tool 100 and the handle 120 is selected to allow easy realization of the ergonomic use of the trigger 130 while maintaining the handle 120. With the second pin 136 placed at the center of the lower base 133'' of the trigger, the trigger 130 is mechanically connected to the first spacer 150, thereby generating hand force transmission. When the trigger 130 is pulled, when the user works against the force of the spring 140, the system of the rails 190, 195 to which the first block 170 and the first spacer 150 are attached is pushed forward, whereby the first spacer The distance between 150 and the second spacer 150' increases.

While the first spacer 150 is movable, the second spacer 150' is fixed to the main body 105 of the guide tool by the second block 170'. This allows the user to apply pressure to the handle 120 in the forward direction without overcoming the spring force, so that when the handle 120 is pressed against the previously fixed structural member 10' or stop point, the user's work can be directly It is converted to move the first structural member 10.

The guiding tool 100 includes a movable spacer 150 and a fixed spacer 150' to allow easy clamping to the first structural member 10. In addition, it enables the guiding tool 100 to be adapted to the width of the There are different imperfect and uneven first structural members 10 used together. However, this movement is only used to fine-tune the distance between the first spacer 150 and the second spacer 150' and the installation of the guide tool 100. In order to enable the guiding tool 100 to be used with the first structural member 10 having a significant difference in width, the first spacer 150 and the second spacer 150' are connected by the first rail 190 and the second rail 195. The relative position of the first rail 190 and the second rail 195 can be adjusted, thereby adjusting the distance between the first spacer 150 and the second spacer 150' when the trigger 130 is in its rest position. The possible relative position between the first track 190 and the second track 195 is predefined by the positioning hole 191 in the first track 190. By inserting position fasteners 194 in the form of screws and bolts through the aligned positioning holes 191 and a single positioning hole 196 in the second rail 195, the positioning hole 196 allows the first rail 190 and the second rail to be mechanically fixed. The relative position of the track 195.

Figure 4 shows a front view of the guiding tool 100. The second spacer 150' is centrally placed in the rear end 103 of the main body 105 of the guiding tool so that the center of the aperture 155 is equidistant from each side 104, 104' of the main body 105 of the guiding tool. In one embodiment of the present invention, the width of the support 101 of the guide tool (marked by arrow L) is designed so that the distance from one side 104 of the guide tool to the center of the orifice 155 is at least the same as the expert suggested The fasteners are placed at the end away from the wooden structural member to avoid damage to the member as long as 26mm. In an embodiment of the present invention, the width of the lip 151 of the spacer is similar to or smaller than the width of the support 101 of the guiding tool (not shown in the figure), so that the width of the lip 151 The placement of the guiding tool 100 is not restricted. The lip 151 of the spacer includes a duct 152 in the form of an area in the lip 151 (not shown in this angle), wherein the thickness of this area is less than the thickness of the remaining part of the lip 151. The duct 152 is placed on each spacer 150, 150' on the side of the lip 151, 151' facing away from the other spacer 150, 150'. The pipe 152 is directly connected to the orifice 155 through the opening 156, where the shavings can leave the orifice 155, so that the shavings will not block the orifice 155 or hinder the movement of the fastener 30 in the orifice 155.

The spacers 150, 150' are mounted on a block (not shown) by T-shaped rails (not shown), and are fixed in place by fixing means such as screws placed in the mounting holes 163 in the spacer. In the illustrated embodiment, there are four mounting holes 163 in the spacer, but other designs with more or fewer mounting holes 163 are foreseen.

The size of the handle 120 is selected to ensure a firm grip and a relatively large surface on which the user can apply pressure. In a preferred embodiment, the width of the handle 120 (shown by arrow K) is 60% or more of the width (shown by arrow L) of the support 101 of the guiding tool.

Figure 5 shows a bottom view of the guiding tool 100. The first spacer 150 and the second spacer 150' are symmetrically placed at the front end 102 and the rear end 103 of the guiding tool 100. The first spacer 150 is connected to the first rail 190. The distance between the first spacer 150 and the second spacer 150' can be adjusted by changing the position of the first rail 190 relative to the second rail 195 (not shown).

To adjust the distance between the first spacer 150 and the second spacer 150' in the rest position, the position fastener 194 is released from the positioning holes 191, 196 in both the first rail 190 and the second rail 195. Then, the first rail 190 and the attached first block 170 and the first spacer 150 slide toward or away from the second spacer 150' while maintaining the same position in the orthogonal direction until the other of the first rail 190 The positioning hole 191 ′ is aligned with the positioning hole 196 of the second track 195. Subsequently, the position fastener 194 is placed through the positioning holes 191' and 196 again to fix the relative position of the first rail 190 and the second rail 195. In the illustrated embodiment of the guiding tool 100, the first rail 190 has three positioning holes 191, 191', 191" for adjusting the distance between the first spacer 150 and the second spacer 150' At the same time, other embodiments with more or less positioning holes 191 are also foreseen. In another embodiment of the present invention, the positioning hole 191 may be connected to the positioning slit, allowing the user to select an intermediate position instead of one of a plurality of predefined positions. In another embodiment of the present invention, the two rails 190, 191 are connected by means other than the fastener 194.

Figure 6 shows an embodiment of the spacer 150 from the guiding tool 100 shown from a different angle. The spacer includes a lip 151 whose thickness (shown by arrow T) determines the distance between the first structural member (not shown) and the fixed structural member or the stopping point where the first structural member 10 will be placed adjacently. distance. The spacer 150 further includes an aperture 155 in which a fastener 30 (not shown) can be placed. The aperture 155 travels through the body 150 of the spacer and a part of the lip 151. The lip 151 of the spacer includes a pipe 152 connected to an opening 156 in the orifice 155. The pipe 152 is an outlet for shavings. When the fastener 30 (not shown) is driven into the first structural member 10 and the second structural member 20, the shavings can be removed from the first structural member 10 and the second structural member 10 The construction member 20 (not shown) is removed. The diameter of the orifice 155 and the size of the fastener 30 should match so that the fastener 30, including a possibly wider head, can freely enter the orifice 155 but with a minimum clearance to allow the fastener 30 to be driven to the first structural member At 10, the angle or swing in the orifice 155 is minimized. In addition, matching the diameter of the aperture 155 and fastener 30 allows all fasteners 30 to be countersunk by roughly the same amount. The standard drill 40 (not shown) has a wider edge near the driving device (not shown), and the spacer 150 is designed so that the drill 40 will stop when the edge hits the opening of the orifice 155. Therefore, the amount of fasteners that will be countersinked is predetermined by the choice of the drill bit, and will remain the same for each fastener installed with the same configuration of spacer and drill bit.

In order to facilitate the operator to replace the spacer 150, the spacer includes a T-shaped track groove 160. The connection achieved by the T-shaped track groove 160 ensures that the spacer 150 is stably installed with necessary tolerances and at an angle intended for angular installation of the fastener 30 in the first and second construction members 10 and 20. The spacer 150 further includes a mounting hole 163 by which the position of the spacer 150 can be fixed, so that the spacer will not swing or slide along the T-shaped rail connection during use. In the illustrated embodiment of the spacer 150, there are four through mounting holes 163, but other embodiments with more or fewer mounting holes are foreseen. The mounting hole 163 may be threaded to accommodate the fixing device to be screwed.

Different embodiments of the spacer design will include slight changes to the characteristics of the spacer 150 so that it can be adapted to different usage requirements. The feature that can be changed is the thickness T of the spacer lip 151. The common thickness of the spacer is 5 mm. Other variants can be, but are not limited to, three millimeters, seven millimeters, and nine millimeters to adapt to different types of wood and the different needs of environments with significant temperature changes. Another feature that can be changed is the width of the spacer lip 151. Another changeable feature of the spacer 150 is the length of the spacer lip 151. The diameter of 155 is another feature that varies between embodiments of spacer 150. Another feature that can be changed is the angle of the aperture 155 in the body of the spacer 150.

The first spacer 150 on the front end 102 of the guiding tool 100 and the second spacer 150' on the rear end 103 of the guiding tool 100 involve the same design. The same first spacer 150 and second spacer 150' can be installed at each end, which is an ideal configuration in most cases because it minimizes the risk of errors. However, if the operator will use spacers 150, 150' with different characteristics, such as different thicknesses of the lips, different variants can be installed at each end 102, 103. Specifically, the T-shaped track groove 160 and the mounting hole 163 are designed in the same manner for all the variants of the spacers 150, 150', so that the spacers can be installed on the same guiding tool 100 while the spacers 150, 150' Other features of 150' changed. In addition, it is possible to use the guide tool 100 with only one spacer 150' installed, for example, if there is no space between the first structural member 10 and the fixed structural member 10' or the stop point For the first structural member 10 (not shown), the first spacer 150 may be omitted and the second spacer 150' fixed at the same time can be kept installed.

Figure 7 shows an embodiment of the block 170 on which the spacer 150 can be mounted. The block 170 includes a T-shaped rail ridge 180 and a mounting recess 183. The first block 170 and the second block 170' are installed near the front end 102 and the rear end 103 of the guiding tool 100, respectively. The block 170 may be releasably installed to the remaining part of the guiding tool 100 through the fixing hole 171, or the block 170 may be integrated in the guiding tool 100. In the illustrated embodiment of the block 170, the fixing hole 171 is through. The T-shaped track ridge 180 is designed to match the T-shaped track groove 160 of the spacer 150. Similarly, the mounting recess 183 has a size and position to match the mounting hole 163 of the spacer 150. The mounting recess 183 may be threaded to accommodate the spacer 150 fixed to the block 170 by screws.

Figure 8a shows how the spacer 150 and the block 170 are releasably engaged. In order to mount the spacer 150 to the block 170, first align the two components so that the bottom of the T-shaped track groove 160 is located on the top of the T-shaped track ridge 180. Then, the spacer 150 slides along the T-shaped rail connection (in the direction of arrow E) until the mounting hole 163 and the mounting recess 183 are aligned. Once the T-shaped rail connection has been engaged, the relative position of the spacer 150 and the block 170 can be ensured by inserting a fixing device such as a screw through the mounting hole 163 of the spacer 150 and into the mounting recess 183 of the block 170. In a common application scenario, the block 170 will remain attached to the guiding tool, while the spacer 150 will be a free part that is replaced by the operator.

Figure 8b shows a cross-sectional side view of the spacer 150 and the block 170 when they are connected. The aperture 155 extends through the spacer 150. In the most common case, the aperture 155 will be parallel to the T-shaped rail ridge 180 and the front of the block 170. However, in some embodiments, the angle of the aperture 155 will be adjusted so that it extends at an angle relative to the T-track connection.

In other embodiments of the present invention, the T-shaped track connection may be changed so that the spacer includes a T-shaped track ridge and the block includes a T-shaped track groove.
