Description

The present invention relates to a floor standing, which is preferably used for detecting the demolition and / or the three-dimensional spatial form of at least one foot. Furthermore, the invention relates to a detection device with a floor stand and a method for detecting the detonation and / or the spatial shape of at least one foot.

From the prior art, various solutions are known to detect the blast or the spatial shape of a foot. Blasting means the distance between the toe and the distance between the heel cap and the ground. The blasting thus includes the so-called top stroke and the rear curve of the heel counter, the so-called Absatzsprengung. The detection of the demolition and / or the spatial shape of a foot serves to produce a custom-made footwear, such as a mountaineering shoe, a ski boot, a sports shoe or a medically specially adapted shoe, hereinafter referred to as shoe, or one of the anatomy of the foot to select the most appropriate shoe from an existing range. In order to detect the blast or the spatial shape of the foot, this lies during the detection on top of a stand. In general, flat floorboards are used on which a person stands upright. Thus, the sole of the foot lies flat on the floor. However, the blasting or spatial form of the foot to be detected differs noticeably in this position from the later spatial form of the inner shoe or the sole of a well-adapted shoe. Further, the sole of the foot is pressed flat depending on the body weight and posture, whereby the foot differs in its longitudinal and transverse extension of a foot during a walking movement.

Therefore, it is the object of the present invention to show a floor standing, which reflects the occurring during the movement blast or spatial form of a foot as accurately as possible. It is another object of the invention to provide a detection device with which the blast and / or the three-dimensional spatial form of a foot can be detected, and a method for this purpose.

The object is achieved with a floor according to claim 1 or alternatively with a floor according to claim 4, a detection device according to claim 13 and a method for detecting the detonation and / or the three-dimensional spatial form of a foot according to claim 19. Advantageous developments are in the dependent claims described.

An inventive floor, preferably for use for the detection of the blast and / or the three-dimensional spatial form of at least one foot has an upper side, a front edge, a rear edge, a first side edge and a second side edge. The longitudinal extent of the floor is defined by the front edge and the rear edge. The transverse extent of the floor is defined by the first side edge and the second side edge.

The floor according to the invention is distinguished from the known from the prior art floorings in that the top has at least one recess for keeping the foot in an anatomical desired position. This depression has an absolute low point. The upper side has a forefoot support surface rising from the low point in the longitudinal extension, a heel support surface rising from the low point in the longitudinal extension, and a ball support surface lying in the region of the low point.

This has the advantage that a foot, which rests on the top of the stand during the detection, has an increased heel position and an elevated front toe plateau with respect to the bales. Thus, the blast or spatial shape of the foot held in the desired position essentially corresponds to the blast or spatial shape of a foot during the walking movement. It is thus also the shape of the shoe sole, which allows a rolling of the foot while walking, modeled.

Advantageously, the upper side has a foot inner edge support surface rising from the low point in the transverse extension and a foot outer edge support surface rising from the low point in transverse extension. As a result, the foot is also slightly raised on both sides in the transverse extension, whereby the spatial form of a foot during a walking movement can be better represented.

Conveniently, the forefoot support surface increases monotonously, in particular S-shaped. It is also advantageous if the heel support surface monotonically increases in particular S-shaped. By the initially flat rising and steeper in the process of becoming support surfaces, the spatial shape of a foot can be simulated during the walking motion.

An alternative solution of the problem is also possible with a floor according to the invention, which is opposite to the known from the prior art floorings characterized in that the topography corresponds to the top of the topography of a last floor of a last.

This has the advantage that suitable floorings are available for selection for a large number of existing strip bottoms. From this assortment, a suitable floor suitable for the anatomy of the foot to be detected is selected. This results in the overall advantage of "mass customization" in that a custom-made shaft builds on an existing groin floor. Thus, the shoe can be made faster and cheaper, or so can be selected directly from the best fitting shoe from an existing range of shoes.

It is advantageous if the top of the stand has at least one positioning aid for positioning the foot in the anatomical desired position. A positioning aid makes it possible to precisely position the foot for the detection process, ie to obtain the desired setpoint position. Optimal positioning during detection is essential for the fit and thus comfort of the shoe to be made or selected.

Conveniently, the positioning aid is designed in the form of a grid or in the form of contours. Based on the grid or the contours of the ball of the foot can be positioned exactly in the ball support surface, resulting in an optimal support of the heel and forefoot.

Developing further, the floor stand may have at least one pedographic pressure sensor for detecting the static foot pressure. As a result, the shoe to be produced, and in particular the sole, can be better adapted to the anatomical conditions of the foot. Further, a pedographic pressure sensor also allows the detection and correction of any misalignments, such as flat feet.

It is advantageous if the surface has photogrammetric markers. These photogrammetric markers serve to assign corresponding markers from individual images which are recorded during an optical detection. By matching the individual markers, a calculation of the three-dimensional spatial form of the foot to be digitized can take place.

It is advantageous if the floor is made of a moldable material. For example, the floor stand can be made of a plastic.

Furthermore, the invention relates to a detection device with a floor according to the invention, which is characterized in that the detection of the detonation and / or the three-dimensional spatial shape of the at least one foot by optical detection means. Thus, the optical detection can be performed separately from the actual calculation of the blast or spatial form.

The optical detection means expediently has a camera, in particular a digital camera for detecting the blasting. From the foot, at least a side view is taken, which depicts the blast. The calculation of the blasting or the parameters such as the peak lift can then be done by a suitable software.

It is advantageous if the optical detection means comprises a three-dimensional digitizer and in particular a photogrammetric digitizer for detecting the spatial form.

Conveniently, the floor standing is designed as a bottom plate of the detection device.

It is advantageous if the floor stand is detachably connected to the detection device. As a result, different floors can be placed in the detection device, so as to take into account the different anatomical conditions of the feet to be detected different people. This can be, for example, different shoe sizes and misalignments. Furthermore, it is conceivable that known or possible misalignments are already compensated by the use of correction documents during the acquisition process.

Conveniently, the detection device each has a floor for the left and right foot. This has the advantage that it can be flexibly reacted to the particular anatomical condition of the foot. It is quite conceivable that the feet of a person are different in width and / or long, or have only one-sided malposition.

1. a) Auswahl eines für die Anatomie des zu erfassenden Fußes geeigneten Standbodens,
2. b) Positionierung des zu erfassenden Fußes anhand der Positionierhilfe, und
3. c) Erfassung der Sprengung und/ oder der Raumform des Fußes durch das optische Erfassungsmittel.

Furthermore, the invention relates to a method for detecting the demolition and / or the three-dimensional spatial form of at least one foot with a detection device according to the invention, the method comprising the following steps:

1. a) selection of a stand suitable for the anatomy of the foot to be detected,
2. b) Positioning of the foot to be detected by means of the positioning aid, and
3. c) detection of the demolition and / or the spatial shape of the foot by the optical detection means.

Thus, by a first inventory of the anatomical conditions of the foot, a suitable floor level can be selected, which is based on the subsequent optical detection.

Appropriately, in step b) any or known malposition of the foot is compensated by correction documents. This has the advantage that misalignments, such as flat feet, can already be taken into account during the detection of the blast or the three-dimensional spatial form of the foot. Thus, the use of deposits in the custom-made shoe can be avoided, as they can already be taken into account in custom-made.

It is advantageous if the detection of the demolition of the foot in step c) takes place photographically. A photographic detection by a camera or the like is associated with manageable effort with high accuracy. For this purpose, preferably a commercial digital camera can be used.

Furthermore, it is advantageous if the detection of the spatial shape of the foot in step c) takes place photogrammetrically. A photogrammetric detection has the advantage that a high accuracy is achieved with manageable technical effort. In general, the photogrammetric detection of the spatial form takes place via an adjustment of a plurality of overlapping images in the display area, which are preferably recorded by a commercially available digital camera.

Conveniently, both feet can be detected simultaneously. This shortens the time required for the entire recording process.

a section through a second embodiment of a floor according to the invention of a detection device according to the invention with non-resting foot.

In the Fig. 1 to 6 is a first embodiment of an inventive floor 1 for detecting the detonation and / or three-dimensional spatial form of a foot 2 shown. The floor 1 has a top 3, a front edge 4 and a rear edge 5. The front edge 4 and the back edge 5 define the longitudinal extension of the floor LE 1. Further, the floor has a first side edge 6 and a second side edge 7. The first side edge 6 and the second side edge 7 define the transverse extent QE of the standing floor 1. The upper side 3 of the standing floor 1 has a recess 8. The recess 8 has an absolute low point 9.

The legs of the recess 8 in the longitudinal direction LE rise from the low point 9. As in particular in the sectional views according to Fig. 1 and Fig. 2 along the section line AA (cf. Fig. 5 and Fig. 6 ) Well, the recess 8 has a rising from the low point 9 in the direction of the leading edge 4 Vorderfußauflagefläche 10. Further, the recess 8 has a rising from the low point 9 in the direction of the back edge 5 heel support surface 11. The top 3 has in the region of the low point 9 a Ballenauflagefläche 12. The Vorderfußauflagefläche 10 and heel support surface 11 rise monotonically in the direction of the front edge 4 and 5 back edge. As in Fig. 1 and 2 shown, these may increase S-shaped, but other gradients and / or curvatures are conceivable.

As in Fig. 3 and 4 illustrated, the recess 8 has a rising from the low point 9 in the transverse direction QE in the direction of the first side edge 6 Fußinnenrandauflagefläche 13 and in the direction of the second side edge 7 rising Fußaußenrandauflagefläche 14. The Fußinnenrandauflagefläche 13 and Fußausßenrandauflagefläche 14 rise monotonically and symmetrically from the low point 9 in the direction of the first side edge 6 and second side edge 7 at. As illustrated, the curvature of the inboard edge support surface 13 and footoutward edge support surface 14 may vary from the low point 9.

Fig. 5 shows a plan view of a floor according to the invention 1. The positioning aid 15 is executed in this embodiment as a grid. The grid is arranged so that the (not shown) foot 2 can be placed on the floor 1 so that the ball of the foot in the area of the low point 9 and thus on the ball support surface 12 come to rest. Furthermore, the upper side 3 may comprise a plurality of photgrammetric markers which are distributed around the positioning aid 15 and which serve for the photogrammetric detection of the three-dimensional spatial form of the foot 2.

Fig. 6 shows a further plan view of a floor according to the invention 1. In contrast to the in Fig. 5 shown standing floor 1, the positioning aid 15 is executed in the form of contours. The contours may also be provided with further markings, such as shoe sizes or the like, to further facilitate the positioning of the foot 2 (not shown). In general, any other form of positioning 15 is conceivable, such as slides, which are arranged displaceably on the top 3 of the floor 1.

Fig. 7 shows a longitudinal section through a second embodiment of a floor according to the invention 1 for detecting the three-dimensional spatial shape of a foot 2. As can be seen well, the floor 1 shown here differs from that in the Fig. 1 to 6 shown floor 1 characterized in that the topography of the top 3 of the floor 1 corresponds to the topography of a dashboard shown in dashed lines 16.

In this embodiment, the upper side 3 of the standing floor 1 has, in addition to the first recess 8 with the first low point 9, a second recess 17 with a second low point 18. The heel support surface 11 extending from the first low point 8 in the direction of the second low point 18 is designed to be curved in an arcuate manner.

Thus, the heel support surface 11 is thus not monotonously increasing as is the case in the first embodiment (see. Fig. 1 to 6 ), but is initially rising and then running down again. Consequently, a wavy course of the upper side 3 of the standing floor 1 results in the illustrated longitudinal sectional view.

In the following, the inventive method for detecting the blasting and / or the three-dimensional spatial form of at least one foot 2 will be described. Before commencement of acquisition or digitization, a base 1 suitable for the anatomy of the foot 2 to be detected is selected. The selected floor 1 is then placed in a detection device and connected to a pedestal.

Following the foot 2 is positioned on the top 3 of the floor 1 so that the ball of the foot on the ball support surface 12 in the region of the (first) low point 9 of the (first) recess 8 come to rest on the basis of the positioning aid 15. Thus, the front toe plateau of the foot 2 is located on the forefoot support surface 10 and the heel region of the foot 2 on the heel support surface 11 (cf. Fig. 1 . Fig. 2 and Fig. 7 ). Here, the front toe plateau of the foot 2 are raised against the bale. Depending on whether a stand was selected with a recess 8, with two recess 8, 16 or any other floor 1, the heel area of the foot 2 is also raised against the bale or is bent by the arcuate increase or otherwise like the spatial shape of a foot 2 adjusted during walking.

Furthermore, after the foot 2 has been positioned, the inside edge of the foot and the outside edge of the foot rest on the foot inner edge support surface 13 and the foot outer edge support surface 14, respectively. As a result, the foot 2 can be easily bent in transverse extension, provided that the floor 1 has a corresponding recess 8 (see. Fig. 3 and Fig. 4 ).

It is conceivable that the desired position of the foot 2 is corrected by correction documents. This may be necessary, for example, in the event of malposition, in order to take these directly into account in the subsequent digitization, in order to manufacture the shoe from a medical point of view. It is also conceivable that the pressure load of the foot is recorded pedographically to adapt the shoe to be produced even more precisely to the conditions of the foot 2.

In the following, the three-dimensional spatial form of the foot 2 or the feet 2 is then detected by an optical detection means. This can be done for example by a photogrammetric digitizing.
