Description of the invention: [Technical field of Wuming] The present invention relates to a jointless structure and-elastically jealous _ meaning "has-elastically deformable mane feet; the structure of the part, the structure is along the height direction The area of the sole of the foot extends to a “Xi?” A knuckle toe (knuckle) area, the foot structure along the longitudinal direction of the bell structure (9) and / 5 ^ I: extended to the one-toe area , Its (cy $ foot part structure (10) has at least two joint pieces (Ghed) 'They are set back and forth along the longitudinal direction, and can move toward or along the front of the foot structure ▲ D interact with each other, and each other A variable intermediate space is formed between them. [Previous technology] It has been known for a long time that prosthetic feet are designed to be jointless. Therefore, the application nature of the feet uses the elastic nature of the materials used to construct the prosthetic feet. There are many The conventional structure, in particular, should improve the walking characteristics of prosthetic feet. Therefore, for example, f, + ¥ $ <, _ 5 mentioned in Wu patent US 4,652326, designing the foot rule (ν_β) area Into many parts, and connect to each other using elasticity In addition, there are known techniques in which the bell and the front of the foot are formed with spring pads in conjunction with air-filled pads, in which the elasticity of walking can be changed by the repeated force of the air in the cymbal. In addition, the European patent EP 0884 933 Β1 It is mentioned that 11 full-term months are formed by using two spring pieces arranged in parallel with each other, and an air-filled pressure pad is arranged between the two spring pieces. The air pressure in the pressure pad is affected by the load of the crotch, so it is strong踵 When stepping for dynamic walking, the yellowness of the forefoot is increased. This can be achieved in a similar way by using a spacer between the two springs 6 200536512 'The position of the spacer depends on the clock step The principle of these solutions is to adjust the spring toughness according to the walking power (force). A fundamental problem in the design of this prosthetic foot is to find the appropriate compromise 'so that the prosthetic foot can be suitable for its main application type, that is, For walking and standing, you need to stand safely with a prosthetic foot. A hard and long forefoot is more suitable. It gives people a sense of security in the south, but using this hard and long Forefoot is not able to achieve consistent walking dynamics. For walking, that is, abrollen movement through the front of the foot, the front of the foot should be designed to be short and soft, but using this front of the foot, There is no sense of security when standing, and the compromises made to date-that is, to be able to take steps as naturally as possible and to stand safely-are unsatisfactory, but because of the need to compromise between the two, they have not reached the optimal level. [Abstract] This The purpose of the invention is to cover the practical properties of the above-mentioned types of prosthetic feet. In order to achieve this purpose, in the above-mentioned types of jointless prosthetic feet, the 4-inch according to the present invention is used to activate (_ ~ ~, English: ⑽batabie) (: As a mechanism and using a controllable action mechanism; 4, the element is in an intermediate space that can affect the distance between the pieces. Bagua into s Therefore, in the prosthetic foot of the present invention, the movable section piece is used in the structure of the front part of t or t. Therefore, the present invention does not include :: pieces of spring hardness adjustment, and use the Can be made a peak change. Book, clock = and / or the structure of the forefoot can be implemented reversibly ^ 'Month can be specially provided-a kind of prosthetic foot, in which the movable section, 7 200536512 is designed and arranged in such a way that it uses its movement to move the foot of the foot forward. The effective length of the part and / or the dip of the triplet part are changed. Therefore, according to the present invention, a different foot structure can be used for standing than for walking, so that it is not necessary (or at least not necessary) to compromise between the two prosthetic foot properties when walking and standing. , Because the structure is changed, when walking, you can use a different structure than when standing. This master mechanism (which moves the knuckle) can be released in a suitable embodiment by deforming the crotch or by deforming the back of the foot. #Transformed from the crotch, can be detected-strong steps, which can be known as a walking cycle. In this case, for example, the recovery effect can be activated by deforming the back of the foot, so the recovery action is Achieved in the Schwungphase, "When standing, the bell is generally not subjected to such a large negative #, so in this case, = the mechanism is not activated, so the benefits of this section are released upon the ground = ❹bearing The effective length of the forefoot is shortened, so that walking is more comfortable. If the bell section is not loaded, the effective length of the forefoot remains large.出 I uses the deformation of the back of the foot to release the action mechanism. It shows that the assembled prosthesis is used as a walking rod to shorten the front of the door. 〃 + * # ㈣ 'This pair of feet will be the next stage. Reply, it ’s done. ”In the case of cattle, the mechanical timing element can be used to create the second example: Two“ Using the foot back movement of the foot W-this is the time for the straight dimension _: Open 1 setting, so only when the relevant Valid. After the engraving of the piece is finished, the restoring mechanism can also be used outside the prosthetic foot to detect the moment sensor on the prosthesis. The structure is activated, for example, using the lower leg 200536512. The moving part using the action device can be a rigid Product bar, switch between two positions, and in one of the positions, the connecting element bridges the earlier continuous cropping mechanism in the front of the foot with the part of Zhong Li. If the release of the ㈣ is released, the rigid @ In this position, it does not cross the elastic connecting element = the connecting piece shortens the effective length of the front of the foot. The restoring effect can be achieved by using the restoring mechanism. In this case, the foot back changes as the front lever of the foot Money structure available with each-way kneeling process ends Achieved, and force = when released. Re-release on the tool. In addition, if the pieces of the movement using the action mechanism are replaced, the wedge can be moved into a wedge shape. The medium-shaped space can be deformed by the load in the direction of shrinking the mold. The wedge moves into the wedge to open the gap. The wrong person makes the rigid element avoid this deformation. The action of the element is to step on the ground and use the front of the foot. Deformation and activation. A suitable timing mechanism can be a mechanical timing-surname-restoration mechanism. It should be a mechanical mechanism. It uses the movement of the foot's recovery element to move into the wedge-shaped middle space so that the front foot is in the middle. = The design is more rigid, so that the area that is important for walking must be removed from the wedge-shaped intermediate space, in order to check the structure, and the wedge adopts this method. If, for example, the wedge-shaped intermediate :: process. If not: use the rigid element (it moves into the intermediate space and enlarges it, so the effective weight of the front of the foot during the walking process is weighted effectively twice to take the rigid element into the wedge-shaped intermediate space to ,-'Is also available in this post In another embodiment, the action mechanism can be shipped in eight movements. Then T contains a fluid 9 200536512 'device', and the element that can be controlled by the action mechanism can be a pad, set =. This fluid can be filled. For this embodiment, a recovery mechanism in the form of a timing element is particularly suitable, and the fluid used is preferably an empty liquid. This recovery mechanism can also be moved from the external part of the prosthetic foot, for example, using a piece protruding from the foot structure. Bowdenzug (Bowdenzug), it can also be operated in the year. 卞 The present invention is described in detail below using the embodiment shown in the figure. (Fufleinsatz), which is covered in a conventional form by a cosmetic cover (1). The foot has a sturdy receptacle element ⑺, which has a receptacle (3) facing towards the toe area, and another Prosthetic parts (not shown) can be connected to the adapter (3). The socket element (4) is connected to a slightly horizontally extending plate-shaped placing portion (Ansatz) (2) via a wedge-shaped intermediate space (3) via a hinge member (5). An elastic wedge (6) is placed in the wedge-shaped intermediate space (3). The plate-shaped placing portion (4) has a -shoulder piece (7) (AbSatZStiick) underneath, which can be formed of the same elastic material, but the hardness of the material is much greater than that of the elastic wedge (6). Between the plate-shaped placing portion (4) of the shoulder member (7), there is a rearward section of a plate-shaped spring element. This bearing is composed of the element (2), the elastic wedge (6), the plate-shaped placing portion (4), the rear-facing section of the plate-shaped spring element (8), and the shoulder portion (7) forming a stack structure (9), Therefore, the plantar structure extends from the plantar region to the toe region of the prosthetic foot along the height direction. 0 The leaf spring element (8)-extends straight into a tough area of the prosthetic foot 10 200536512 with a front foot structure (10). The front foot structure (10) extends along the toe region of the prosthetic foot to the toe region of the prosthetic limb. The front part of the foot (10) consists of rigid joints (1 1), (12), (13), (14), (15), (16), (17), (18), (19) and two elastic middle sections. (20) (21). The rigid joint pieces (12) to (19) are adjacent to each other, and because of their shape, they have only a small inclination to each other. A first elastic intermediate section (20) is provided between the adaptor element (2) and the first rigid section (11), and between the first rigid section (11) and the second rigid section (丨 2) A second elastic intermediate section (21) is provided between them. The elastic middle section (20) (21) extends across the entire height range of the forefoot structure (1 0), and therefore the rigid section (2) (1 丨) and the rigid section (1 1) (12) The corresponding intermediate spaces (22) (23) between) are filled. Therefore, the foot structure is composed of a sacral structure (9) in the height direction and a forefoot structure (10) in the length direction, both of which are composed of several pieces. In the embodiment shown in FIG. 1, a rigid lever (24) is rotatably supported on an edge of the receiver element [this edge faces the first f-domain member (20)]. The free joint (25) is supported on the l-shaped shoulder ⑽ of the first rigid joint ⑴) in the stage ⑷ shown in Figure 1 so that the cup (24) bridges the receiver element (2) And the middle-section workshop (22) of the first-section piece (11), so that the first elastic intermediate section piece (20) will not be compressed. On the plate-shaped protrusion (4) of the connector section ⑺, there is a protrusion (mount 28) that protrudes downward, and the protrusion (28) passes through a flexible band (27) and the Free (2 5) connection. In the state of ^ * shown in stage (3), which is heavy and strong (for example, the person who walked in the place 11 200536512), the elastic wedge (6) in the concrete structure (9) dust shrinks, so the protrusion (28) Relative to the gray bearing, the part moves backwards, so the flexible end of the branch (27) is used to move the free end (25) of the branch # (24) from the l-shaped shoulder of the first rigid joint. (%) pull out. In this way, the first elastic intermediate piece (20) is no longer held down by the lever (24), and is therefore elastically pushed in in a manner favorable to walking. In this way, the effective front foot length of walking is shortened by Δ 丨, As shown in Figure 丨.

For this purpose, the leaf spring element (8) is provided with an additional-flexible band (29) in the toe region attachment [for example, approximately in the plantar region of the plantar toe of the foot] in the toe region 2 It is also connected to the free end (25) of the lever (24). By bending the plate-shaped spring element (8) with the instep of the foot, the other flexible band (26) is brought to the stage (a). The addition of the effective foot anterior osteosynthesis (10) stage (3) facilitates the assembly of the prosthetic limb and a safe standing sensation. If walking continues' and therefore bears a strong kind of load according to stage (6), it is automatically adjusted to the stage (C) which is favorable for walking. In this way, you can make adjustments for standing and opposing walking, so that the effective front foot length of the prosthetic foot automatically matches. The ridge structure (9) and forefoot structure (丨 ... of the embodiment shown in FIG. 2 are in principle consistent with the first embodiment. However, there is a rigid wedge ㈦) embedded in the wedge-shaped intermediate space (3 ), The rigidity and (6,) are also provided in the intermediate space (3) so as to be movable in the longitudinal direction. The moving movement of the wedge (6,) is controlled by a continuous cup (30), and the connecting rod is rotatably driven on the arm of the 6-arm arm. The double-f lever ⑼ is rotatably provided on the rigid joint (14) of the two-arm lever (3 1) of 12 200536512 to receive the joint (2). There is another link (32) pivotally connected to the other arm, and this link is connected to the anterior foot structure (10) in a stage of 0.... : The intermediate space (3) corresponds to the still effective part of the shape of the mold (6,). Guanggen is small. This small, raised shoulder height corresponds to a large effective forefoot recovery and therefore creates a feeling of safety when standing.

It is used as a lever, and the two-arm lever is used in a reverse direction, and υ is so pulled that the link (30) connected to the mold (6,) is a load of a tie rod) into the mold Space (3) goes in. This is due to the clock structure (9) m. In this way, the height of the shoulder is increased, and the length of the foot is reduced, so it can be used for comfortable walking. Reverting to a favorable standing order p (Tuffan, " standing and W's effect can be achieved by a recovery mechanism. For example, it can also be achieved by hand via a sheath cable or the like. Shown in Figure 3 In the embodiment, the sex wedge (6). The adapter piece of the adapter is inserted into each space called a wedge shape, / in the middle of the ^ piece ^) is rigid in the stage 图 in Figure 3 Wedge formation: The middle space (22) is the largest when Daguang b, so adjust it at this stage-take the effective front foot length, which is good for standing. Phase side cantilever (33), the cantilever is on the first, firmly connected, ^ protrusion (4). ㈣⑴) itself and-the piston (35) dry silver β, the ancient base is guided in a red device (34) in the receiver rib, rb + piece (2). 13 200536512 =: (34) there is a return spring (36), which springs the piston (35) in the direction of 踵 and a throttle valve (37) at the lower end of the cylinder (34), so that the piston (35) is subject to. The recovery force of the Rebound Man (36) is delayed by the air that is slowly vented through the throttle. If the prosthetic person leaves the standing stage shown in stage (3) and starts the walking process, he replays his body onto the cymbal in stage (b), and the bullet / 1 '(6) is pious, In this way, the lateral cantilever (33) is lifted up |, so the die (20,) moves up. In this way, the intermediate space (22) between the adapter section (2) and the first rigid section (11) becomes smaller, so the effective forefoot length is shortened, which makes walking easier, and the throttle valve (37) The adjustment value of is selected so that the wedge (20,) will not return at the walking: constant step frequency. Only when there is no bell movement for a certain period of time following the shrinkage effect of the elastic wedge (6), the reset spring will reset the wedge (20,) to the stage ("position via the cantilever (33)). ^ In the embodiment shown in FIG. 4, the first intermediate space (22) between the receiver section (2) and the first rigid section (11) is designed so that it can support a pad inside (38) A pump device is provided in the 踵 -shaped intermediate space (3) of the 踵 structure (9), whereby a fluid can be pumped out of the 塾 (38) through a check valve (check valve ^ ⑷) to A storage room (40). The pad (38) is emptied in this way, so that the intermediate space ⑽ becomes smaller and the effective front foot length of the stage ⑹ walk is shortened. If the bell action is omitted, it is because the prosthetic person is fitted Standing, the fluid is slowly charged from the storage chamber (40) through the throttle valve (42) and a check valve (43) into the pad (38). Larger. So it is better to stand. In the embodiment shown in Figure 5, a pad (44) is also used, 14 200536512 Here the pad is placed in the wedge-shaped middle space (3), however, of course, it can also be located in an intermediate space (22) (23) of the forefoot structure. The pad (44) can be pressurized with air using an air pump device (45), which (45) —The pump device (34) as shown in Fig. 4 is placed in the wedge-shaped intermediate space (3), but here the pad (44) is directly pumped with air.
要將充氣的墊回復，可將它與一放氣開口經一節流閥 (圖未不）連接。如果（在步行時）不會發生踵動作，則墊（44) 排空成階段⑷所示的狀態。鐘構造（9)的高度減少，使得足 前部有效長度較大，因此有助於站立。 —將墊(44)充氣’使踵構造⑼高度加大，並因此使有效 足前部長度縮短，如此，在階段(b)有助於步行。 由圖示的實施例可看屮·兮q 乂 有出·该足刖部有效長度可利用足 動作本身造成改變，其方法 万去^可將足珂部構造（1 〇)的實際 長度加大或將踵構造（9)的离择料, Λ 、 )巧度交小，相關之可控制旳的節 件的動作可利用踵動作或蕤差 错義足向足背彎曲而釋放。回復 機構可用對應的方式利用屈 θ ^ ,, 飞』用足動作控制，也可用手動或特別 疋疋時控制回復。 【圖式簡單說明】 第1圖係本發明第一實 Α知例中一義足的内部構造在三 個不同階段的示意側視圖； 第2圖係本發明第二實 、⑪例中一義足的内部構造在三 個不同階段的示意側視圖； 一 第3圖係本發明第三眘 、⑦例中一義足的内部構造在二 個不同階段的示意側視圖； 傅^仕一 35 200536512 第4圖係本發明第四實施例中一 個不同階段的示意側視圖； 第5圖係本發明第五實施例中一義 個不同階段的示意側視圖。 的内部構造在三 的内部構造在三To restore the inflatable cushion, connect it to a bleed opening via a throttle valve (not shown). If the 踵 action does not occur (while walking), the pad (44) is emptied into the state shown in stage ⑷. The reduction in the height of the bell structure (9) makes the effective length of the forefoot larger and therefore helps to stand. -Inflating the cushion (44) ' increases the height of the 踵 structure, and thus shortens the effective front foot length, so that it is helpful for walking in stage (b). From the example shown in the figure, it can be seen that the effective length of the plantar part can be changed by using the foot action itself. The method can be removed ^ The actual length of the foot part structure (10) can be increased Or, the 料, Λ,) of the 踵 structure (9) are small, and the related joint-controlling action of the 旳 can be released by bending the foot towards the instep by using the 踵 action or the erroneous foot. The reply mechanism can use flexure θ ^ ,, fly ′ to control the foot movement in a corresponding way, and can also control the reply manually or in a timely manner.
