Description

Technical Field

[0001] This invention relates to a foot pedal device that is easy to install and its installation method. Background Technology

[0002] Workshops typically install foot pedals on the crossbeams of support frames. The traditional method involves drilling threaded holes in the crossbeams and securing them with bolts. However, this method requires precise machining; errors in machining can easily lead to installation problems. Installation necessitates aligning each hole with the screws, requiring significant time spent working at height. Summary of the Invention

[0003] The purpose of this invention is to overcome or at least mitigate the shortcomings of the prior art and to provide a foot pedal device and its installation method that are easy to install.

[0004] This invention provides an easy-to-install foot pedal device, comprising a plurality of crossbeams fixedly arranged and extending along a first direction, the crossbeams being spaced apart in a second direction perpendicular to the first direction; a foot pedal fixed to the plurality of crossbeams across the plurality of crossbeams; and a threaded connector for connecting the crossbeams and the foot pedal.

[0005] The foot pedal has at least one short through hole and at least one long through hole extending along the second direction. The short through hole and the long through hole are for the threaded portion of the threaded connector to pass through. The threaded connector is movable along the second direction within the long through hole when it is not tightened.

[0006] In the second direction, the short through hole is located on the first side of the left and right sides of the crossbeam, and the long through hole is located on the second side of the left and right sides of the crossbeam.

[0007] The threaded connector clamps the foot pedal to at least a portion of the first and second sides of the crossbeam through the short through hole and the long through hole, respectively, thereby fixing the foot pedal to the crossbeam.

[0008] In at least one embodiment, the crossbeam is an I-beam.

[0009] In at least one embodiment, a clamping plate is further included, the clamping plate having a threaded hole that mates with the threaded portion of the threaded connector, and at least a portion of the I-beam is located between the clamping plate and the foot pedal, such that the threaded connector and the clamping plate secure the foot pedal to the I-beam.

[0010] In at least one embodiment, in the second direction,

[0011] The first end of the foot pedal includes at least one of the short through holes located on the first side of the I-beam, and,

[0012] The second end of the foot pedal includes at least one of the elongated through holes located on the second side of the crossbeam.

[0013] In at least one embodiment, in the second direction,

[0014] The foot pedal device also includes an I-beam located in the middle of the foot pedal.

[0015] The foot pedal also includes at least one of the short through holes located on the first side of the I-beam in the middle.

[0016] In at least one embodiment, the clip extends along the first direction.

[0017] In the first direction, the clip has at least two threaded holes through which the screw portion of the threaded connector passes, and the length of the clip is not greater than the width of the foot pedal.

[0018] In at least one embodiment, the clip includes: a base plate portion; and a raised portion protruding from the base plate portion, the raised portion being located on one side of the threaded hole in the width direction of the clip.

[0019] At least a portion of the I-beam and the raised portion are clamped between the base plate and the foot pedal on both sides of the threaded hole.

[0020] In at least one embodiment, the height of the raised portion protruding from the base plate is the same as the height of at least a portion of the I-beam, thereby fixing the base plate to the foot pedal parallel to the foot pedal.

[0021] In at least one embodiment, the long through hole and the short through hole are stepped holes that are larger at the top and smaller at the bottom, and the head of the threaded connector is hidden in the stepped hole so as not to protrude from the upper surface of the foot pedal.

[0022] The present invention also provides a method for installing a foot pedal device according to the present application, comprising:

[0023] Clip installation steps: Pass the threaded portions of the multiple threaded connectors through the short through holes and the long through holes on the foot pedal, and pre-tighten the threaded connectors onto the threaded holes of the clips, so that the threaded connectors are pre-connected to the clips;

[0024] Foot pedal installation steps: Place the foot pedal on the I-beam, so that the clips on the threaded connector are close to the first and second sides of the left and right sides of the I-beam respectively;

[0025] First clamping step: Move the foot pedal along the second direction so that the clamping piece on the threaded connector located in the short through hole can cooperate with the foot pedal to accommodate at least a portion of the first side of the I-beam, and tighten the threaded connector located in the short through hole so that the head of the threaded connector and the clamping piece together clamp the first side of the I-beam.

[0026] Second clamping step: Move the threaded connector located in the long through hole along the second direction, so that the clamping piece on the threaded connector located in the long through hole can cooperate with the foot pedal to accommodate at least a portion of the second side of the I-beam, and tighten the threaded connector located in the long through hole, so that the head of the threaded connector and the clamping piece together clamp the second side of the I-beam.

[0027] In an embodiment of at least one method for installing a foot pedal device, it further includes:

[0028] Take another foot pedal, repeat the clamp installation step and the foot pedal placement step, then move the foot pedal along the first direction until it is close to the previous foot pedal, and continue to perform the first clamping step and the second clamping step.

[0029] The foot pedal device according to the present invention has low requirements for processing technology and is easy to install. Attached Figure Description

[0046] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement the present invention, and are not intended to exhaustively describe all possible ways of the invention, nor to limit the scope of the invention.

[0047] The following is based on Figure 1A , Figure 1B and Figure 2 An easy-to-install foot pedal device according to one embodiment of the present invention is described, which includes a crossbeam, a foot pedal 20, a clamp 30, and a threaded connector 40.

[0048] Preferably, the crossbeam is an I-beam 10, so that the threaded connector 40 can clamp the side of the I-beam 10.

[0049] The foot pedal device of this embodiment may include multiple parallel H-beams 10 and multiple foot pedals 20 parallel to each other on the H-beams 10. The length direction of the H-beams 10 is the first direction Y.

[0050] The threaded connector 40 can be a bolt or screw, etc., which includes a threaded portion and a head with a diameter larger than the threaded portion.

[0051] The foot pedal 20 has a short through hole 21 and a long through hole 22. The short through hole 21 is only large enough for the threaded portion of the threaded connector 40 to pass through (but not the head of the threaded connector 40). Preferably, the short through hole 21 is a circular through hole, which facilitates drilling and machining of the foot pedal 20. The long through hole 22 extends along a second direction X, and the threaded portion of the threaded connector 40 can move along the second direction X after entering the long through hole 22. The second direction X is perpendicular to the first direction Y.

[0052] In the second direction X, the short through hole 21 and the long through hole 22 are located on the first and second sides of the left and right sides of the I-beam 10, respectively. When the threaded connector 40 through the short through hole 21 contacts the first side of the I-beam 10, the threaded connector 40 through the long through hole 22 can move within the long through hole 22, thus moving away from or towards the second side of the I-beam 10. The first sides of multiple I-beams 10 are in the same direction (e.g., all are...). Figure 1A and Figure 1B The right side of the I-beam 10), and the second sides of multiple I-beams 10 are also in the same direction (e.g., all are...). Figure 1A and Figure 1B (Left side of I-beam 10).

[0053] Preferably, the foot pedal device of this embodiment further includes a clamping plate 30. The clamping plate 30 has a threaded hole 31 for engaging with the threaded portion of the threaded connector 40. See also Figure 4 The clamp 30 is positioned below the I-beam 10. When the foot pedal device is installed, at least a portion of the I-beam 10 is located between the clamp 30 and the foot pedal 20. See also Figure 3 Preferably, the clip 30 includes a base plate portion 32 and a raised portion 33 protruding from the base plate portion 32. The raised portion 33 is located on one side of the threaded hole 31 in the width direction (i.e., the second direction X) of the clip 30. See also Figure 4 When the foot pedal device is installed, at least a portion of the I-beam 10 and the raised portion 33 are clamped between the base plate portion 32 and the foot pedal 20 on both sides of the threaded hole 31.

[0054] More preferably, the height of the raised portion 33 protruding from the base plate portion 32 is the same as the height of at least a portion of the I-beam 10 (i.e. the portion of the I-beam 10 that is clamped), thereby fixing the base plate portion 32 to the foot pedal 20 in parallel with the foot pedal 20, ensuring that the force on both sides is uniform when the threaded connector 40 is tightened, so as not to tilt, and the installation is stable and reliable.

[0055] Preferably, in the first direction Y, the length of the clamp 30 is not greater than the width of the foot pedal 20, and the clamp 30 has at least two threaded holes 31 arranged along the first direction Y. Correspondingly, the short through holes 21 and long through holes 22 on the foot pedal 20 are also configured in at least two pairs, so that the clamp 30 is connected to the foot pedal 20 and the I-beam 10 through at least two sets (e.g., four) of threaded connectors 40, making the connection more stable. The connection between the clamp and the at least two threaded connectors 40 restricts the rotation of the clamp 30 around the screw portion. In the first clamping step and the second clamping step described below, the threaded connectors 40 can be tightened directly from above without fixing the clamp 30 from below, making the installation more convenient.

[0056] Preferably, in the second direction X, the foot pedal device of this embodiment may have three I-beams 10, located at the beginning and end and the middle of the foot pedal 20 respectively (it may but not necessarily be the exact center), to strengthen the supporting effect and connection strength of the I-beams 10 on the foot pedal 20.

[0057] For a foot pedal 20, each I-beam 10 may have threaded connectors 40 on both its first and second sides; or, each I-beam 10 may have threaded connectors 40 on its first side, but only one I-beam 10 may have threaded connectors 40 on its second side. For a foot pedal, at least one threaded connector 40 is located on the first side of an I-beam 10, and at least one threaded connector 40 is located on the second side of an I-beam 10. That is, it is sufficient to ensure that a foot pedal 20 clamps at least one I-beam 10 from at least both sides in the second direction X.

[0058] Preferably, the short through hole 21 and the long through hole 22 on the foot pedal 20 are stepped holes, wider at the top and narrower at the bottom. This allows the head of the threaded connector 40 to be concealed within the stepped holes without protruding from the upper surface of the foot pedal 20. This makes the foot pedal device of this embodiment more ergonomic and integrated, preventing the protruding threaded connector 40 from hindering walking and reducing the likelihood of wear or detachment. (Refer to...) Figure 2 When the foot pedal 20 includes an upper panel and a lower panel formed by bending the upper panel downwards, the stepped hole can be composed of a large hole in the upper panel and a small hole in the lower panel of the foot pedal 20. The head of the threaded connector enters from the large hole in the upper panel and rests against the small hole in the lower panel, so as not to protrude from the surface of the upper panel of the foot pedal 20.

[0059] The following is based on Figures 5 to 9 An installation method for an easy-to-install foot pedal device according to one embodiment of the present invention is described.

[0060] The beam fixing step involves fixing the beam, preferably an I-beam 10, with the first direction Y as the length direction, and multiple I-beams 10 are arranged in parallel.

[0061] Specifically, multiple I-beams 10 can be fixed to the frame 50 using screws. The frame 50 may, by way of example, include two longitudinal connectors 52 and two transverse connectors 51 (see reference). Figure 1B and Figure 5 Both the longitudinal connector 52 and the transverse connector 51 can be, for example, I-beams. Since multiple I-beams 10 are fixed to the frame 50, the relative position or distance of the multiple I-beams 10 is affected by the machining accuracy of the threaded holes on the frame 50. If the foot pedal 20 and the I-beam 10 are connected through the round hole on the foot pedal 20 and the threaded hole on the I-beam 10, installation problems may occur due to the influence of machining accuracy.

[0062] It is understood that the beam fixing step is not a necessary step in this application, and the foot pedal installation method of this application can be carried out with the beam fixed on the frame 50.

[0063] In the clamp installation step, the threaded parts of multiple threaded connectors 40 are passed through the long through hole 22 and the short through hole 21 of the foot pedal 20, and the threaded connectors 40 are pre-screwed onto the threaded hole 31 of the clamp 30, so that the threaded connectors 40 and the clamp 30 are pre-connected together.

[0064] The foot pedal installation steps are as follows: place the foot pedal 20 on the crossbeam (that is, the I-beam 10, hereinafter referred to as the I-beam 10), so that the threaded connector 40 is close to the first and second sides of the left and right sides of the I-beam 10 respectively.

[0065] Preferably, in the foot pedal placement step, if the foot pedal device includes a clamp 30, the foot pedal 20 is placed on the I-beam 10, such that the clamp 30 on the threaded connector 40 is close to the first and second sides of the left and right sides of the I-beam 10, respectively.

[0066] In the first clamping step, the foot pedal 20 is moved along the second direction X so that the clamping piece 30 on the threaded connector 40 located in the short through hole 21 can cooperate with the foot pedal 20 to accommodate at least a portion of the first side of the I-beam 10, that is, the I-beam 10 is inserted between the clamping piece 30 and the foot pedal 20, and the threaded connector 40 located in the short through hole 21 is tightened so that the head of the threaded connector 40 and the clamping piece 30 together clamp the first side of the I-beam 10.

[0067] In the second clamping step, the threaded connector 40 located in the long through hole 22 is moved along the second direction X so that the clamping piece 30 on the threaded connector 40 located in the long through hole 22 can cooperate with the foot pedal 20 to accommodate at least a portion of the second side of the I-beam 10, and the threaded connector 40 located in the long through hole 22 is tightened so that the head of the threaded connector 40 and the clamping piece 30 clamp the second side of the I-beam 10 together.

[0068] For the installation of multiple foot pedals 20, the following operation can also be performed: Take another foot pedal 20, repeat the clamp installation steps and foot pedal placement steps, then move the foot pedal 20 along the first direction Y until it is close to the previous foot pedal 20, and continue the first clamping step and the second clamping step.

[0069] This invention has at least one of the following advantages:

[0070] (i) The foot pedal device of the present invention does not require drilling holes in the crossbeam (I-beam 10), but only in the foot pedal 20. Furthermore, due to the setting of the long through hole 22, the positional accuracy requirement between the long through hole 22 and the short through hole 21 is low, and the processing accuracy requirement for drilling is low, which reduces processing costs. Moreover, it is friendly to the installation of multiple foot pedals 20 and will not accumulate hole position errors.

[0071] (ii) The installation method of the foot pedal device of the present invention is quick and convenient. It does not require alignment with the hole position. Just push the foot pedal 20 (first clamping step) and then push the threaded connector 40 (second clamping step) to quickly complete the installation and save installation time.

[0072] (iii) The foot pedal device of the present invention uses a clamp 30, which not only increases the contact area with the I-beam 10 and makes the connection more stable, but also directly provides threaded holes 31 on the clamp 30, so that the clamp 30 can replace the nut and cooperate with the threaded connector 40. In the preferred embodiment, the clamp 30 includes at least two threaded holes 31 for cooperating with the threaded connector 40. During the tightening of the threaded connector 40, it is not necessary to manually enter the foot pedal to fix the clamp 30, avoiding the trouble of finding and fixing the nut during installation and disassembly, making the installation and disassembly process more convenient.

[0073] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make various modifications to the above embodiments of the present invention under the guidance of the present invention, without departing from the scope of the present invention.

[0074] For example, two long through holes can be used to replace a pair of holes, one short through hole and one long through hole.
