Definitions
- handles for tools that work in a special way the function of the respective tool can be adjusted.
- handles for screwdrivers that have a hexagonal or pentagonal cross section with rounded edges. Both the cross-sectional shape as well as the longitudinal section shape to the needs of the tool and adapted to the size of a hand accepted as standard.
- the adaptation also happens according to the way the tool is operated. Screwdrivers are usually operated in a different way than, for example Chisels in which a pushing movement occurs more strongly than one rotating.
- the previous adaptation to ergonomics was primarily attaches importance to the form, while at most certain surface properties have been optimized to improve grip.
- the invention has for its object to provide a handle that optimally adapted to the size and shape of a special hand of a user can be.
- the invention proposes a handle with the Claim 1 mentioned features. Developments of the invention are the subject of subclaims.
- the partial deformability of the handle surface makes it possible for the Grip yields when, for example, a user is at a certain point accesses more than another. Even if his hand is of the standard form and standard size can be better grasped in this way and treating the handle. How great the compliance executed depends on the circumstances of the individual case and the type of Handle or the type of object that are used with this handle should.
- the handle should be able to be used wherever a user contacts one Touch object to operate, hold, move or the like.
- An example of such an object is a wheelbarrow called, in which a user grips two spars around the wheelbarrow to lift and push.
- Another example is a wheelchair that handles for pushing the wheelchair.
- Other examples are stretchers, with handles at both ends to at least hold the stretcher temporarily carried by two people.
- Sports equipment can also have such handles, for example in sports studios, where there are strength training devices where a user also attacks must in order to exert a force.
- the handle should be on tools, especially hand tools be used.
- An example of such a tool is a screwdriver.
- a deformability of the handle can also be used with other similar tools used, for example in files, hammer handles, chisels, Screw clamps, axes or the like.
- the deformability of the handle surface can vary, for example, over the entire Extend the area of the grip element on which a user engages. It but it is also conceivable that the deformability on part of the handle surface is limited, for example to the part on which the user with the Palm attacks while the parts of the handle on which the user attacks with your fingertips, are not deformable.
- Such Design of the handle surface is useful, for example, with screwdrivers in which certain areas of the handle surface are designed such that they are designed to turn the tool quickly with your fingertips.
- the deformability the grip surface to a certain depth below the grip surface is limited. So the entire handle should not be deformable inwards but only a part of the grip surface below the surface. Inside should a hard core stand still, not only for connection to the tool can serve, but also a firm hold for the transmission of movement from the hand to the tool.
- the deformation is a restoring deformation.
- the manner The deferral can be different, the deferral of course should not take place in a time range that is in the minutes range, but rather in the seconds range.
- the deformability the surface is limited to one layer.
- This layer can be on different Depending on the need, the handle may have a different thickness or Have depth.
- a larger, coherent layer should be used Area that can be understood, for example, via a certain axial length of the handle extends, for example over the entire length Handle length.
- the deformability is at least individual partially separated areas is limited. It can be Act areas that are located at the locations of the handle, where one particular heavy hand stress occurs.
- the deformability of a part of the handle surface can, for example, thereby that an element made of a deformable material is present is connected to the handle element.
- the attachment or connection this deformable element can be done in different ways. In particular, it can be provided, for example, that it is deformable Element forms a layer.
- the coating over the deformable layer regardless of whether it is is a layer of a separate element or an integral layer, can differ, for example, at different points on the grip element be fat. This way too, a different strength Deformability can be achieved depending on the application.
- At least one deformable Element is formed by a pillow or the like.
- an elastomer can be used as the deformable material. which has the corresponding deformation properties.
- the deformable material is a gel or a silicone, so that if necessary, one or more gel pads are attached to the handle can.
- Gels have certain properties that they have in mind for the here make the intended application appear suitable, namely not one too fast recovery and a resilience that is particularly suitable appears.
- the deformation of gels is primarily due to a change in the form, but not by changing their volume.
- gel pads are already known for other applications, but not for Design of the surfaces of tool handles.
- deformable areas for limitation the deformation to certain parts of the areas are.
- the invention proposes, with an approximately polygonal cross section of the Handle element in particular to form the corner areas deformable, since there in Normally there is a greater strain on the hand.
- this at least one deformable Element is arranged in a depression corresponding to its size, so that its accessible surface matches the remaining surface of the grip element runs flush.
- a deformable layer as a sleeve or a form separate element, which is pushed onto a grip element or in is otherwise attached to this.
- An example of such Tool is a hammer, where there is a great style that you can focus on can slide a sleeve made of deformable material.
- Another example is the style of a shovel or broom.
- Figures 1 to 6 are a particularly important example of handles for Screwdriver shown.
- Handles for files, chisels, awls or the like are similar cases in which the invention can be used.
- the handle shown in longitudinal section in FIG. 1 contains a handle element 1 a relatively hard plastic that is injection molded around a tool shank 2 is.
- the tool shank 2 is thus non-rotatable and also in the axial direction firmly connected to the grip element 1.
- a layer 5 made of a deformable material is attached to the outer surface of the handle 1 around, i.e. with the exception of those assigned to the tool End face 4.
- the deformable material can be, for example, an elastomer layer act, i.e. a material in which the deformation is caused by compression of the material is made possible.
- the coating 6 is very thin and extends to just before the front side 4 of the grip element. It practically forms one Protective layer and a layer for holding the layer 5 of elastomer material together or from other deformable material.
- the simplest example is the layer 5 made of deformable material over the entire Grip surface of the grip element 1 spread and has the same everywhere Thickness.
- Figure 2 shows a longitudinal section corresponding to Figure 1 through a second Tool handle.
- the grip element 1 contains a small distance from it end cap 7 a shoulder 8 forming recess, which is practical forms a recess in the handle surface.
- a coating 10 is formed which defines the distance between the end of the layer 9 and fills the shoulder 8 and covers the layer 9 to the outside.
- the Cover 10 extends up to the front side 4 of the handle element 1.
- the sleeve 9 made of deformable material unavailable. So here is no compliance or deformability of the Given. As can also be seen in FIG. 2, the thickness increases the deformable layer 9 shortly before the end facing the end face 4 somewhat, while the thickness of the coating 10 increases. This In this way, a handle is created in which the compliance to a part of the Length of the handle is limited while in the area 11 where the user with your fingers to quickly turn the handle, no compliance is available. The handle is also not deformable in the region of the tip 7.
- Figure 3 shows a section through a further embodiment, in turn a grip element 1 made of hard material around a tool shank 2 is injected.
- the crest 7 is similar to that of the previous one Embodiment in Figure 2.
- the area in which a layer 12 of deformable Material is arranged, is compared to the embodiment of Figure 2 shortened again. This area practically only covers half of the area Tool handle length.
- the deformable one Area only from individual elements 12, see the section of the figure 4, in the area of the corners of an approximately pentagonal cross section of the Handle are arranged.
- the width of these areas 12 is hardly larger than the rounded part of the corners of the cross section.
- the individual areas 12 are also made of deformable material by webs 13 connected to each other, the webs 13 through channels in the handle element are passed through. This creates a five-pointed star made of webs 13, the individual areas 12 of deformable material with each other connect.
- This embodiment is of particular interest if the material forming the deformable areas 12 is a material is where the deformation is not due to compression, but is achieved by a change in shape, for example by one Gel material. To prevent the gel material from flowing away, both the webs 13 and the areas 12 are surrounded by a protective layer 14 be, see the longitudinal section of Figure 3. If here a user on a presses on a gel pad at a certain point, the shape changes, but not the volume of the gel pads connected by the webs 13.
- Figure 5 shows the side view of the one shown in Figures 3 and 4 in section Handle. It can be seen here that the individual areas 12 are deformable are, separate areas from each other in the surface, and they also have a different width over the length of the handle. hereby is a particularly favorable adaptation of the surface properties of the Griffs reached to the human hand.
- Figure 6 shows a longitudinal section combined with a side view, similar to that Embodiment according to Figures 3 to 5.
- individual gel pads 15 available, which are not connected to each other, but in individual recesses are arranged. Again, it ensures that the surface the gel pad 15 is flush with the rest of the surface 16 of the grip element 1 runs.
- Figure 7 shows a sleeve enclosed in a sheath 16 a sleeve-like formed material 17, for example a gel pad.
- the gel-like Material 17 can, for example, from one end face into the casing 16 are inserted, which is then closed, for example by a weld seam 18.
- Such a sleeve can, for example, on a shovel handle or a hammer handle can be pushed on to get the improved one To enable handling properties.
- Gel is to be understood here to mean all gel-like substances, for example also silicone or other viscous materials.
