Description
- The invention relates to an in-line roller skate, more particularly to a modular in-line skate frame assembly.
- Referring to Figures 1 and 2, a conventional in-
line skate frame 1 is made from extruded aluminum. The extruded aluminum undergoes a machining process to form integrally theframe 1. Theframe 1 includes two spaced-apartlateral plates 11, and a plurality of spaced-apartcurved ribs 12 connected between thelateral plates 11. When a plurality of wheels (not shown) are rotatably connected between thelateral plates 11, thecurved ribs 12 are located facing the outer peripheries of the wheels so as to provide sufficient stiff support to thelateral plates 11. - Although the conventional in-
line skate frame 1 is formed integrally and has a stiff structure, it has the following disadvantages in terms of production and use: - 1. During the formation process of the
frame 1, the aluminum is initially heated to a sufficient temperature to provide the aluminum with a predetermined degree of plasticity, then fed through a mold by a hydraulic press to form a rectangular extruded aluminum member. The extruded aluminum member is then machined, and finally undergoes a finishing process to form the desired structure of the in-line skate frame 1. Since theframe 1 is designed to have a strong structure and an appealing appearance, the machining process must be performed in a precise and meticulous manner, such that the manufacturing process of the conventional in-line skate frame 1 is very difficult and complicated. - 2. During the machining process of the aforementioned extruded aluminum, a significant amount of waste material is produced, resulting in an effective use of the aluminum that's often below 25%. The mining, recycling and production of aluminum involve high costs and significant effort, and place a burden on the environment. Therefore, aluminum should be used as effectively as possible, ideally with an effective use of 25% or greater. If this waste material is disposed of directly and not recycled, a high consumption of material occurs.
- 3. Through the presence of the
curved ribs 12, thelateral plates 11 have a stiff structure. When one of thelateral plates 11 receives an external shock, the impact absorbed by said one of thelateral plates 11 will be transmitted to the otherlateral plate 11 through thecurved ribs 12 to dampen the impact, thereby enhancing the stiffness of thelateral plates 11. However, since theframe 1 is formed integrally and has no areas of resiliency, when the impact is very strong, theframe 1 tends to deform easily, particularly at the junctures of thelateral plates 11 and thecurved ribs 12. - Referring to Figure 3, another conventional in-
line skate frame 3 is shown tobe similar to the aforementioned in-line skate frame 1. Particularly, theframe 3 is formed integrally, and includes twolateral plates 31. However, theframe 3 has no curved ribs 12 (see Figure 2) . Theframe 3 is provided with aslot 32 in eachlateral plate 31. Theslot 32 extends along the length of theframe 3 so that eachlateral plate 31 is formed with a double-wall configuration. - Since the
frame 3 is formed integrally, it encounters problems similar to those of theaforementioned frame 1, that is, a complex manufacturing process and high consumption of material. Furthermore, the double-wall configuration of eachlateral plate 31 only weakens the structure of theframe 3 so that eachlateral plate 31 tends to deform easily and may even crack when met with a strong impact. - Therefore, the object of the present invention is to provide a modular in-line skate frame assembly that is easy to manufacture, that can be produced in such a way that the base material is used effectively, and that has a low production cost, as well as sufficient strength and resiliency.
- According to this invention, a modular in-line skate frame assembly comprises a shoe mounting horizontal plate, two spaced-apart lateral plates, and a fastening unit. The shoe mounting horizontal plate includes a plurality of spaced-apart lateral plate connecting portions. The lateral plates extend downwardly and respectively from two opposite ends of the horizontal plate, and has a plurality of spaced-apart link portions provided on a respective one of the lateral plates. The link portions are connected respectively to the lateral plate connecting portions. The fastening unit extends through the lateral plate connecting portions and the link portions for fastening together the horizontal plate and the lateral plates.

- Figure 1 is a perspective view of a conventional in-line skate frame;
- Figure 2 is a schematic side view of the in-line skate frame of Figure 1;
- Figure 3 is a schematic side view of another conventional in-line skate frame;
- Figure 4 is an exploded perspective view of the preferred embodiment of a modular in-line skate frame assembly according to the present invention;
- Figure 5 is a front view of the preferred embodiment, which is partly sectioned to show a groove in a horizontal plate;
- Figure 6 is a sectional view of the preferred embodiment, illustrating how a fastening unit secures the horizontal plate to two lateral plates;
- Figure 7 is an assembled schematic view of the preferred embodiment in a state of use;
- Figure 8 is a front view of the preferred embodiment with one of the lateral plates being flexed inwardly; and
- Figure 9 illustrates an alternative lateral plate usable in the present invention.
- Referring to Figures 4 and 5, the preferred embodiment of a modular in-line
skate frame assembly 2 according to the present invention is shown to comprise two spaced-apartlateral plates 21, a shoe mountinghorizontal plate 22, and fourfastening units 23. - The
lateral plates 21 are symmetrical, and extend along a longitudinal direction. Each of thelateral plates 21 includes amain body 211 having a continuous wave-like structure, five spaced-apartwheel connecting portions 212 projecting downwardly from a bottom end of themain body 211, and four spaced-apartlink portions 213 projecting upwardly from a top end of themain body 211. Since themain body 211 has a wave-like structure, thewheel connecting portions 212 and thelink portions 213 are arranged in a staggered configuration. Themain body 211 is provided with a plurality ofdecorative holes 214 so as to reduce the weight of themain body 211. - The shoe mounting
horizontal plate 22 is disposed between thelateral plates 21, and includes anintermediate portion 221, heel andtoe support portions 222, 222' formed on two opposite sides of theintermediate portion 221, and a plurality of spaced-apart lateralplate connecting portions 223. The lateralplate connecting portions 223 include afront connecting portion 223a projecting downwardly and forwardly from the toe support portion 222', a rear connectingportion 223b projecting downwardly and rearwardly from theheel support portion 222, and two middle connectingportions 223c projecting downwardly from theintermediate portion 221. Each of the lateralplate connecting portions 223 is tubular, and is disposed in a transverse direction transverse to the longitudinal direction of thelateral plates 21. The lateralplate connecting portions 223 are connected respectively to thelink portions 213 of thelateral plates 21. Each of the heel andtoe support portions 222, 222' has anelongated slot 224 through which a fastener may be secured to a heel or a toe portion of a boot (shown in Figure 7 in phantom lines). Twoelongated grooves 225 are formed respectively in bottom faces of theintermediate portion 221 and the toe support portion 222'. - Referring to Figure 6, in combination with Figures 4 and 5, the
fastening units 23 are provided for fastening together thelateral plates 21 and thehorizontal plate 22 through thelink portions 213 and the lateralplate connecting portions 223. Each of thefastening units 23 includes an internally threadedtubular member 231 that extends through thecorresponding link portion 213 of one of thelateral plates 21, the corresponding lateralplate connecting portion 223, and into thecorresponding link portion 213 of the other one of thelateral plates 21, and an externally threadedtubular member 232 that engages threadedly the internally threadedtubular member 231 so that thehorizontal plate 22 is secured between the twolateral plates 21. - Referring to Figure 7, each of the
lateral plates 21 and thehorizontal plate 22 cooperatively define a plurality of spaced-apart apertures 24, each of which is located between two adjacent ones of thelink portions 213 below thehorizontal plate 22. In this embodiment, there are sixapertures 24 defined by thelateral plates 21 and thehorizontal plate 22 with threeapertures 24 on each side of thehorizontal plate 22. - During assembly of the boot and the
frame assembly 2, five roller wheels (shown in Figure 7 in phantom lines) are respectively and pivotally connected between thewheel connecting portions 212 of the twolateral plates 21. Two of the roller wheels project respectively into thegrooves 225 in the horizontal plate 22 (only one is visible in Figure 5). Next, the heel and toe portions of the boot are secured respectively to the heel and toe supportportions 222, 222' of thehorizontal plate 22 through theelongated slots 224. The assembly of the boot and theframe assembly 2 is, in this state, ready for use by the user. - The advantages of the in-line
skate frame assembly 2 of the present invention in terms of manufacture and use are as follows: - 1. The
lateral plates 21 and thehorizontal plates 22 are made individually by punching, and are fastened together by using thefastening units 23. Thus, the manufacturing process of the in-lineskate frame assembly 2 of the present invention is easy, quick, and simple. - 2. Since an amount of material approximating that of the completed
lateral plates 21 and thehorizontal plates 22 is punched to form these elements, there is little waste of material. - 3. Since the
lateral plates 21 and thehorizontal plate 22 are made individually, are fastened together through thelink portions 213 and the lateralplate connecting portions 223, and cooperatively define theapertures 24 which can absorb shock, when one of thelateral plates 21 receives an external shock or when the road surface is rough, as shown in Figure 8 in phantom lines, theframe assembly 2 can undergo temporary deformation to thereby produce suitable resilience and in this way absorb shock forces, thereby avoiding the situation where the majority of the shock forces enters the skater's body. The remaining impact or shock is absorbed through the connecting points, so that thehorizontal plate 22 or the other one of thelateral plates 21 are not easily affected. - 4. In the preferred embodiment, another way in which the material is more effectively used and its resilience further enhanced is by producing the parts by hot forging.
- It is generally known that properly treated Aluminum 7075 that is hot-forged nears the mechanical properties of St 52.
- The parts of the
frame assembly 2 can be easily produced by hot-forging, and the resulting increase in strength will allow for further effective use of the material, as will the hot-stamping itself. - Figure 9 illustrates an alternative form of the lateral plates 21 (only one is visible) which can be used in the present invention. The top and bottom ends of the
main body 211 of eachlateral plate 21 are substantially straight.
