DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] The technical characteristics of the present disclosure will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings. The dimensions, proportions, sizes, shapes, or application states depicted in the figures are for illustrative purposes only to explain the technical features of the invention. They do not represent actual structural designs, as explicitly stated herein.

[0040] Please refer to FIGS. 1A to 4B, which are a first and second structure schematic view, a local structure schematic view of a foldable demolition hammer trolley in accordance with a preferred embodiment of the present disclosure, an application schematic view of the foldable demolition hammer trolley setup for demolition hammer in accordance with a preferred embodiment of the present disclosure, and a first and second structure schematic view of foldable demolition hammer trolley folding diagram in accordance with a preferred embodiment of the present disclosure. The present invention discloses a foldable demolition hammer trolley 9 used for placing a demolition hammer 8 to perform floor removal operations, such as removing wood flooring glued with silicone, or removing tiles, vinyl floors, and epoxy floors. The foldable demolition hammer trolley 9 comprises a first frame 1 and a second frame 2. The first frame 1 includes a main rod 10, a moving assembly 11, and a pedal assembly 12. The moving assembly 11 is mounted at the bottom end of the main rod 10 and includes a fixed axle 111 and two wheels 112. The two wheels 112 are respectively mounted at opposite ends of the fixed axle 111 and located on opposite sides of the main rod 10. The pedal assembly 12 includes a connecting part 121 and a pedal pad 122. The pedal pad 122 is fixedly mounted on one side of the connecting part 121, while the other side of the connecting part 121 is pivotally connected to the fixed axle 111, allowing the pedal assembly 12 to be folded towards or away from the main rod 10. Additionally, one side of the pedal pad 122 may be covered with tire rubber, providing excellent wear resistance and compression resistance properties to enhance durability and lifespan.

[0041] The second frame 2 is pivoted to one side of the first frame 1, comprising a support frame part 20, a carrying frame part 21, at least one telescopic sleeve rod 22, an adjustment member 23, a first fixing assembly 24, and a second fixing assembly 25. One end of the support frame part 20 is pivoted to the main rod 10, allowing the support frame part 20 to be folded towards or away from the main rod 10. The support frame part 20 and the pedal assembly 12 are located on opposite sides of the main rod 10. The carrying frame part 21 is pivotally mounted opposite to the support frame part 20 on the main rod 10, allowing the carrying frame part 21 to be folded towards or away from the support frame part 20. One end of the telescopic sleeve rod 22 is fixedly mounted on the support frame part 20, while the other end is fixedly mounted on the carrying frame part 21, located between the support frame part 20 and the carrying frame part 21. Preferably, there are two telescopic sleeve rods 22 symmetrically positioned to provide stable support relative to the support frame part 20 and the carrying frame part 21.

[0042] The adjustment member 23 is positioned between the support frame part 20 and the carrying frame part 21 to adjust the angle between the carrying frame part 21 and the support frame part 20. Preferably, the adjustment member 23 can be a strut structure, where one end of the adjustment member 23 is fixed to either the carrying frame part 21 or the support frame part 20, and the other end is movable to abut against the support frame part 20 or the carrying frame part 21, enabling the adjustment of the support frame part 20 and the carrying frame part 21 to the desired angle and then securing it in place. Alternatively, the adjustment member 23 can also be a belt structure, where one end is fixed to the support frame part 20, and the other end is connected to the carrying frame part 21 in a movable manner, allowing the adjustment of the angle between the carrying frame part 21 and the support frame part 20 by changing the total length of the adjustment member 23.

[0043] The first fixing assembly 24 is positioned on the carrying frame part 21 and located on the side facing the telescopic sleeve rod 22, serving to secure the handle 80 of the demolition hammer 8. In one implementation, the first fixing assembly 24 has a first space 249 and is a detachable structure, allowing the handle 80 of the demolition hammer 8 to be secured within the first space 249. Preferably, an anti-slip object, such as a non-slip mat, can be installed on the first fixing assembly 24 to make the installation of the demolition hammer 8 more stable. The second fixing assembly 25 is also installed on the carrying frame part 21, positioned on the side of the carrying frame part 21 opposite to where it connects to the telescopic sleeve rod 22 and corresponds to the first fixing assembly 24. The second fixing assembly 25 secures the body 81 of the demolition hammer 8. Similarly, in one implementation, the second fixing assembly 25 also has a second space 259 and is a detachable structure, allowing the body 81 of the demolition hammer 8 to be secured within. In this configuration, an optimal folded state is achieved by pivoting the pedal assembly 12 to fold against the main rod 10, and pivoting the support frame part 20 and carrying frame part 21 towards the top side of the main rod 10. The main rod 10 passes through the first space 249 and/or the second space 259, and can be partially secured by the first fixing assembly 24 and/or the second fixing assembly 25, forming a fully folded and secured state, making it convenient for carrying and storage. In FIGS. 4A and 4B, the first fixing assembly 24 and the second fixing assembly 25 are shown as examples of detachable structures. When folding, the first fixing assembly 24 and a part of the second fixing assembly 25 can be detached, and the main rod 10 can be flipped to overlap with the second frame 2. The detached part of the second fixing assembly 25 can then be reassembled, and the first fixing assembly 24 can be attached to either the main rod 10 or the second fixing assembly 25. The first fixing assembly 24 can even fix the second fixing assembly 25 and the main rod 10 together. Alternatively, when folding, the first fixing assembly 24 can be treated like the second fixing assembly 25, with a part of the first fixing assembly 24 being detached first, then reassembled after the main rod 10 is overlapped with the second frame 2.

[0044] In the operational state, the pedal assembly 12 of the first frame 1 is pivoted so that the pedal pad 122 of the pedal assembly 12 rests against the ground, and the carrying frame part 21 and the support frame part 20 of the second frame 2 are pivoted open. This allows the demolition hammer 8 to be fixed to the carrying frame part 21 in an inclined position, as shown in FIG. 3.

[0045] Therefore, during floor removal operations, the operator can use the structural pedal pad 122 and hold the main rod 10 to gain greater pushing force. In other words, through the foldable demolition hammer trolley 9, the operator can quickly and easily remove the floor without needing excessive back strength. This allows the operator to avoid muscle and joint strain or damage caused by prolonged use of the demolition hammer 8. Additionally, the foldable demolition hammer trolley 9 facilitates easy transportation of the demolition hammer 8 and offers advantages in mobility. The unique folding design of the foldable demolition hammer trolley 9 ensures convenient storage and travel.

[0046] Regarding various embodiments of the components of the foldable demolition hammer trolley 9, the main rod 10 includes a first rod portion 101 and a second rod portion 102. In one embodiment, the first rod portion 101 is assembled with the moving assembly 11 at its bottom end, while the second rod portion 102 is mounted at the top end of the first rod portion 101. The second rod portion 102 is detachable from the first rod portion 101 and includes a handle 1021 at its end facing the first rod portion 101. The main rod 10 is designed to optionally include the second rod portion 102 as a detachable structure, providing versatility based on operational needs, types of floor to be removed, and the structure of the demolition hammer 8. In another embodiment, the bottom end of the second rod portion 102 is inserted into the top end of the first rod portion 101 and secured through a pin 3, offering advantages in ease of disassembly and assembly, allowing operators to adjust the structural state of the foldable demolition hammer trolley 9 more effectively. In FIG. 1B, the illustration of the pin 3 is hidden, and this is hereby clarified. Additionally, considering most application requirements for better force assistance, the length of the second rod portion 102 can be set between 25 to 30 inches, such as 26 or 27 inches, to achieve optimal length performance.

[0047] In another embodiment, a bolt 4 is positioned between the main rod 10 and the support frame part 20, allowing the main rod 10 to move back and forth relative to the pedal assembly 12. By adjusting the tightness of the bolt 4, the main rod 10 can be either slightly movable for floor demolition or fixed in place for folding and storage of the foldable demolition hammer trolley 9, depending on its application state.

[0048] In a preferable embodiment of the pedal assembly 12, it includes at least one auxiliary wheel 123 mounted on the connecting part 121. The auxiliary wheel 123 facilitates smoother movement when operators step on the pedal pad 122 and push the foldable demolition hammer trolley 9. Furthermore, the connecting part 121 comprises two rods 1211 symmetrically positioned, each hosting the auxiliary wheel 123. This symmetrical arrangement of the two rods 1211 ensures stability during movement of the foldable demolition hammer trolley 9 and assists in smooth mobility with the help of the auxiliary wheels 123. Ideally, the auxiliary wheels 123 are securely fixed to the two rods 1211 in a lockable manner, positioned alongside the two rods 1211 for enhanced assistance in movement. Additionally, considering the overall width and performance requirements of the foldable demolition hammer trolley 9, it is preferable to maintain a wheelbase of the two wheels 112 between 7 to 11 inches. This width ensures the foldable demolition hammer trolley 9 is not too wide for convenient storage and carrying, yet provides stability during operational movements. For instance, the wheelbase of the two wheels 112 can be set to approximately 9 inches, with each wheel having a width of around 2 inches. In this configuration, the maximum distance between the two wheels 112 can be around 11 inches.

[0049] In addition, concerning the telescopic rods 22, aside from the option mentioned earlier of having two telescopic rods 22, in one embodiment, the telescopic rods 22 can be elastic rods designed to provide outward pushing force to the support frame part 21. When using the demolition hammer 8, which is tilted and leaning against the support frame part 21, having the telescopic rods 22 as elastic rods helps maintain the desired angular separation between the support frame part 21 and the support frame part 20. This elastic property allows the telescopic rods 22 to exert outward force against the support frame part 21, thereby securely supporting both the support frame part 21 and the demolition hammer 8 on top of it.

[0050] Continuing with the description of the first fixed component 24, please refer to FIGS. 5A and 5B, which are a first depict schematic diagram and a second depict schematic diagram of partial structures of a preferred embodiment of the first fixed component in this invention. In a preferable embodiment, the first fixed component 24 includes a length adjustment piece 242 and a clamping piece 243. One end of the length adjustment piece 242 is fixed to the support frame part 21. The clamping piece 243 comprises a first body 2431 and a second body 2432 arranged oppositely. The first body 2431 is fixed relative to the support frame part 21 at the end pivot setting, with the length adjustment piece 242 provided to adjust the distance between the clamping piece 243 and the support frame part 21. The clamping piece 243 is pivotable relative to the length adjustment piece 242. The handle 80 of the demolition hammer 8 is secured within the space formed by framing of the first body 2431 and the second body 2432, corresponding to the previously mentioned first space 249. Thus, the configuration of the first fixed component 24 can be adjusted according to the model and structure of the demolition hammer 8, allowing the foldable demolition hammer trolley 9 to be used with various types of demolition hammers 8.

[0051] Furthermore, the length adjustment piece 242 may include a fixed rod 2421 and a sliding component 2422. The fixed rod 2421 is fixed to the support frame part 21, while one end of the sliding component 2422 is sleeved on the fixed rod 2421, and the other end is pivotally connected to the clamping piece 243. The sliding component 2422 is capable of sliding relative to the fixed rod 2421, facilitating easy adjustment of the clamping piece 243 and the distance between the clamping piece 243 and the support frame part 21. Moreover, in one embodiment, the first body 2431 of the clamping piece 243 has a first arc section 24311 and two first extension sections 24312 located on opposite sides of the first arc section 24311. Similarly, the second body 2432 has a second arc section 24321 and two second extension sections 24322 located on opposite sides of the second arc section 24321, so that the first body 2431 and the second body 2432 are respectively -shaped. The first extension sections 24312 and the second extension sections 24322 are designed to abut against each other and are equipped with a locking piece 5 at their positions, allowing the first arc section 24311 and the second arc section 24321 to clamp together, forming a circular space where the handle 80 of the demolition hammer 8 can be securely clamped. The locking piece 5 can adjust the distance between the first body 2431 and the second body 2432, thereby changing the size of the space formed by clamping the first arc section 24311 and the second arc section 24321. This arrangement allows operators to quickly and conveniently adjust the assembly state of the clamping piece 243. Specifically, the locking piece 5 can be loosened first to place the handle 80 of the demolition hammer 8 between the first body 2431 and the second body 2432, adjust the second body 2432 according to the handle 80 to the desired position, and finally lock the locking piece 5.

[0052] Next, please also refer to FIGS. 6A and 6B, which are a first depict schematic diagram and a second depict schematic diagram of partial structures of a preferred embodiment of the second fixed component in this invention. The second fixed component 25 can be designed either as a monolithic structure or assembled from multiple parts. If assembled from multiple parts, the second fixed component 25 offers the advantage of easy partial repair and replacement, while enabling adjustable movement relative to the fixed state of the demolition hammer 8. In a preferred embodiment, the second fixed component 25 may include a first part body and a second part body. The first part body is used for assembly with the support frame part, while the second part body is used to mutually assemble with the first part body, thereby achieving the effect of adjusting their distance in one direction. In addition to this configuration, as indicated in this example, the second fixed component 25 may consist of a first fixed main body 251, a second fixed main body 252, a third fixed main body 253, and a fourth fixed main body 254. One side of the first fixed main body 251 is mutually connected to the support frame part 21, and the other side of the first fixed main body 251 is assembled with the second fixed main body 252, the third fixed main body 253 is located on one side of the second fixed main body 252 and is connected to it, and the fourth fixed main body 254 is positioned on one side of the first fixed main body 251, and one side of the fourth fixed main body 254 is assembled with the carrying frame part 21, and the other side of the fourth fixed main body 254 is assembled with the third fixed main body 253. The first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254 are combined to form an outer contour in the shape of a quadrilateral frame. The body 81 of the demolition hammer 8 is fixed in the space formed by the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254, corresponding to the previously mentioned first space 249, and the distance between the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254 can be adjusted. Through the aforementioned structural design, it is advantageous in terms of part replacement; if any part is damaged, only the damaged part needs to be replaced, thus effectively saving material costs. At the same time, it allows the second fixed component 25 to adjust the distance between parts in two directions.

[0053] Furthermore, in a preferred embodiment, the support frame part 21 has a track 211. The first fixed main body 251 and the fourth fixed main body 254 are respectively movably installed in the track 211 and can move within the track 211 to adjust the distance between the first fixed main body 251 and the fourth fixed main body 254.

The first assembly insert 2512 can slide within the first assembly hole 2521 to adjust the distance between the first fixed main body 251 and the second fixed main body 252. The second assembly insert 2522 can slide within the second assembly hole 2531 to adjust the distance between the second fixed main body 252 and the third fixed main body 253. The third assembly insert 2532 can slide within the third assembly hole 2542 to adjust the distance between the third fixed main body 253 and the fourth fixed main body 254. Through these structural features, the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254 have the advantage of easy assembly and adjustment, providing enhanced convenience for operators in applications.

[0054] Preferably, the first fixed main body 251 and the fourth fixed main body 254 are respectively installed in the track 211 through a connecting piece 7. The first fixed main body 251 further has a first carrying insert 2511, and the fourth fixed main body 254 further has a second carrying insert 2541. The first carrying insert 2511 and the second carrying insert 2541 are placed within the track 211. By means of the first carrying insert 2511 and the second carrying insert 2541, the first fixed main body 251 and the fourth fixed main body 254 can be more stable when moving along the track 211. This arrangement also provides a more stable structural state between the first fixed main body 251, the fourth fixed main body 254, and the carrying frame part 21. The connecting piece 7 can be, for example, a screw and a movable screw component. The movable screw component is positioned on the track 211. This allows the first fixed main body 251 and the fourth fixed main body 254 to be installed on the track 211 in a locked manner through the connecting piece 7. The movable screw component enables the first fixing body 251 and the fourth fixing body 254 to move along the track 211.

[0055] Here's a refined example regarding the structure of the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254. The first fixed main body 251 includes a first L-shaped section 2518 and a first dividing section 2519. The first dividing section 2519 is inclined and connected at both ends to form a first pentagonal frame with the first L-shaped section 2518. The first carrying insert 2511 extends from one end of the first L-shaped section 2518, and the first assembly insert 2512 extends from the other end of the first L-shaped section 2518 in the opposite direction to the first carrying insert 2511.

[0056] The second fixed main body 252 includes a second L-shaped section 2528 and a second dividing section 2529. The second dividing section 2529 is inclined and connected at both ends to form a second pentagonal frame with the second L-shaped section 2528. The second assembly insert 2522 extends from one end of the second L-shaped section 2528, and the first assembly hole 2521 is formed by a recess at the other end of the second L-shaped section 2528.

[0057] The third fixed main body 253 includes a third L-shaped section 2538 and a third dividing section 2539. The third dividing section 2539 is inclined and connected at both ends to form a third pentagonal frame with the third L-shaped section 2538. The third assembly insert 2532 extends from one end of the third L-shaped section 2538, and the second assembly hole 2531 is formed by a recess at the other end of the third L-shaped section 2538.

[0058] The fourth fixed main body 254 includes a fourth L-shaped section 2548 and a fourth dividing section 2549. The fourth dividing section 2549 is inclined and connected at both ends to form a fourth pentagonal frame with the fourth L-shaped section 2548. The third assembly hole 2542 is formed by a recess at one end of the fourth L-shaped section 2548, and the second carrying insert 2541 extends from the other end of the fourth L-shaped section 2548. Wherein the first pentagonal frame and the second pentagonal frame are arranged in a mirrored configuration, the second pentagonal frame and the third pentagonal frame are arranged in a mirrored configuration, the third pentagonal frame and the fourth pentagonal frame are arranged in a mirrored configuration, and the fourth pentagonal frame are arranged in a mirrored configuration with the first pentagonal frame.

[0059] Through these structural features, the second fixed component 25 can effectively reduce manufacturing costs (by designing each part as a frame), while maintaining a certain degree of fixed strength and structural rigidity.

[0060] To enhance the combined strength of the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254 after adjusting the spacing, the first fixed main body 251 and the second fixed main body 252 are further secured together by a first screw 60. The first screw 60 passes through the first dividing section 2519 and the second dividing section 2529. Similarly, the third fixed main body 253 and the fourth fixed main body 254 are secured together by a second screw 61 passing through the third dividing section 2539 and the fourth dividing section 2549. This locking method securely fixes the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254, providing operational convenience.

[0061] Considering the typical structural type of the demolition hammer 8, the maximum distance between the spaces formed by clamping the first fixed main body 251, the second fixed main body 252, the third fixed main body 253, and the fourth fixed main body 254 ranges from 2 to 4 inches. This allows the second fixed component 25 to be designed to an appropriate size while also meeting the structural requirements of most demolition hammer 8 configurations.

[0062] Please also refer to FIGS. 7 and 8, which are a first depict schematic diagram and a second depict schematic diagram of the application of a preferred embodiment of the foldable demolition hammer trolley in floor demolition operations in this invention. During floor demolition operations, the pedal assembly 12 pivots so that the pedal pad 122 rests against the ground. The carrying frame part 21 and the support frame part 20 pivot into an expanded state. The demolition hammer 8 is then fixed to the carrying frame part 21 and inclined against it. The operator then steps on the pedal pad 122 and pushes forward on the main rod 10, causing the second frame 2 to move forward. The drill part of the demolition hammer 8 can thus pry the floor off the ground. By repeating these actions, floor demolition operations can be performed quickly and easily. In this method of application, the foldable demolition hammer trolley 9 allows the operator to apply greater force to the demolition hammer 8 through leverage, making it easier to remove the floor. Moreover, in this operating process, the operator does not need to exert excessive force on their back muscles or joints over long periods of operation, thereby effectively mitigating common adverse effects associated with using the demolition hammer 8. Additionally, when the main rod 10 includes a removable second rod section 102, for example, when working on floor types that are easier to remove, removing the second rod section 102 can enhance operational speed. It should be noted that the entire weight of the foldable demolition hammer trolley 8, manufactured according to the above structural patterns, is approximately 50 lbs, emphasizing its lightweight characteristics.

[0063] In summary, the foldable demolition hammer trolley of the present invention is designed with a special frame structure. During floor demolition operations, it allows operators to apply sufficient force to push the demolition hammer without relying heavily on their back muscles, leveraging the principle of leverage. This effectively addresses the adverse effects that operators commonly face when relying solely on their physical strength over extended periods of work. Moreover, the foldable nature of this invention enhances its convenience for storage, transportation, and travel. The structure of the invention includes many detailed technical features. For example, the upper side portion of the main rod is designed to be detachable, allowing operators to adjust the assembly state of the foldable demolition hammer trolley according to their needs. Additionally, auxiliary wheels can be added to the pedal assembly to facilitate smoother movement of the foldable demolition hammer trolley. Furthermore, specific structural configurations are disclosed for the first fixed component and the second fixed component, enabling adjustable spacing or directional positioning functions. This detailed design enhances the overall performance and efficiency in various aspects. The invention also proposes optimal dimensional conditions for certain parts to ensure that the foldable demolition hammer trolley achieves appropriate size and optimal application efficiency. Overall, the invention introduces advanced features that not only improve operational ergonomics and efficiency but also enhance the versatility and practicality of the foldable demolition hammer trolley in various operational scenarios and storage conditions.
