Abstract
The invention relates to a protective cap for a lens or ocular end of an optical device, such as an observation device, with an end wall and with a tubular cap casing extend around at least certain regions of the end wall. The end wall comprises at a first layer in at least certain regions and an insert part made separately from it, and the material of the first layer or insert part has a higher modulus of elasticity than the material of the cap casing.
Description
- The invention relates to a protective cap for a device, in particular a lens or ocular end of an optical device, such as an observation device, as described in
claim 1. - Document DE 939 192 C discloses a protective cover made from a transparent material for lenses and oculars of optical devices, in particular photographic lenses. In this instance, a part of the protective cover is made from a transparent material so that it has a magnifying effect. As a result, a magnifying glass is always available for obtaining a magnified view, making it easier to determine the values which need to be set for the lens or ocular. A protective cover which can be used as a magnifying glass offers a major advantage for persons with impaired sight because the numbers provided on the lens, closure and aperture ring are usually very small and are difficult to make out without visual aids. The entire protective cover is made from one material, and may additionally be provided with a velvet tape in the region where the protective cover is fitted on the lens.
-
Document DE 1 761 392 U discloses protective covers for lenses of field glasses, and the covers are individually attached to the bottom ends of the carrying strap of the field glasses. The covers can therefore be individually fitted on the lens barrels of the field glasses and are held on the barrels by static friction. The ends of the carrying strap are usually threaded through eyes attached to the field glasses and the strap then pulls the covers up to the eyes once they have been removed. They therefore lie firmly against the field glass housing and no longer prevent use of the field glass. - The underlying objective of this invention is to propose a protective cap for a lens or ocular and an optical device, in particular an observation device, which facilitates and therefore improves handling when fitting the protective cap on the optical device.
- This objective is achieved by the invention on the basis of the characterizing features defined in
claim 1. - The surprising advantage gained as a result of the characterizing features defined in
claim 1 resides in the fact that the end wall and cap casing of the protective cap are made from materials which have a different bending stiffness or bending strength from one another or a different hardness, and the respective properties of the individual components can therefore be specifically adapted to suit the particular intended purpose. A sufficient protective and damping effect can be obtained for the optical device as a result, especially in the external peripheral region of the protective cap, whilst nevertheless stiffening or reinforcing the end wall for the fitting or snap-fitting operation of the protective cap. As a result, the protective cap as a whole can firstly be fitted in a pre-centered position on the ocular and/or lens of the optical device, after which a light pressure merely has to be applied centrally to the end wall, in particular at its center, so that the entire protective cap is fully fitted or pushed onto the lens or ocular to be protected in the region of the end wall by means of this pressing force. In the case of protective caps which are of a very soft and elastic design, this centrally positioned fitting movement is not possible. In the past, it ha been necessary to apply pressure distributed around the external circumferential edge of the protective cap in order to be able to fit or snap-fit it correctly. Due to the stiffer or more bending resistant material used for the end wall, the fitting operation can now take place using one finger. - Also of advantage is another embodiment defined in
claim 2, where at least the end wall of the protective cap can be inserted in a sort of sandwich component made from materials with a differing modulus of elasticity, which on the one hand enables the stiffness of the protective cap in the region of the end wall to be specifically pre-defined, whilst on the other hand nevertheless imparting an adequate protective and damping effect to the entire protective cap for the optical device. Due to the multi-layered design, the material used for the snap-fitting operation on the optical device and hence the one with the lower modulus of elasticity than the other layer is reinforced to the degree that the entire protective cap can firstly be placed on the ocular and/or lens in a pre-centered position, after which another central pressing force merely has to be applied to enable the protective cap to be fully fitted or pushed on in the region of the end wall by means of this pressing force. - Another possible embodiment is defined in
claim 3, whereby a component can be produced in a manufacturing process during which the insert part or first layer can be embedded or on-molded. Furthermore, however, the protective cap can still be easily adapted to suit different intended purposes. - As a result of the embodiment defined in
claim 4, in addition to centering the cap casing internally by means of the circumference of the ocular or lens end, an additional hold for the entire protective cap can be provided on its external face. As a result, the end of the optical device to be protected can be covered around its entire circumference and is therefore optimally protected. - As a result of another embodiment defined in
claim - Also of advantage is another embodiment defined in
claim 7 because the process of fitting and removing the protective cap on or from the optical device can also be made easier, and air is able to flow in and out at predefined points. During fitting, this enables any air which might otherwise be trapped between the protective cap, barrel and lens to escape so that no air cushion is created which might push the protective cap off. - The advantage of the embodiment defined in
claim 8 is that it also makes the process of removing the protective cap easier because if the leg of the retaining shoulder is sitting firmly and tightly, air is already able to flow as far as the cap casing from outside. The fitting operation is also made easier because any quantity of air contained in the housing compartment for the ocular can also easily escape from it. This further improves the hold of the protective cap on the optical device. - Also of advantage is another embodiment defined in
claim 9 because by opting for the high modulus of elasticity, the degree of stiffness or reinforcement can be fixed for the entire end wall, which means that the degree of flexing which occurs during the fitting movement can be significantly reduced compared with conventional protective caps. - As a result of the embodiment defined in
claim 10, the stiffness or flexibility of the end wall can easily be adapted to suit different conditions of use. - In the case of another embodiment defined in
claim 11, it is possible to manufacture the layers separately. Accordingly, the first layer or insert part is made first of all in a separate manufacturing process and is joined to the material of the other layer or cap casing during another forming process used to produce to it, for example molded to or embedded in it. - Also of advantage is another embodiment defined in claim because the choice of mutual materials enables a perfectly bonded connection to be obtained between the components to be joined.
- The advantage of the embodiment defined in
claim 13 is that not only is it possible to make the end wall stiffer, the cap casing can also be made stiffer. - In the case of another embodiment defined in
claim 14, a minimal deformation distance of the end wall in the radial direction is achieved in the pre-tensioned retaining state on the optical device to be protected on the one hand, in addition to which there is no need for excessive deformation of the whole of the end wall during the fitting movement. This minimizes fitting force and also increases the retaining force in the fitted state. - Another embodiment is defined in
claim 15, whereby it is possible to opt for a slimmer wall thickness for the insert part but a bending-resistant or stiff design of the end wall can nevertheless be achieved. - Also of advantage is an embodiment defined in
claim 16 because force can be transmitted more rapidly in co-operation with the shoulder in the cap casing during the movement of pushing on the protective cap and the deformation distance of the end wall can also be kept short. - The advantage of an embodiment as defined in
claim 17 is that an additional mechanical connection is obtained between the two layers disposed one on top of the other. - In this respect, an embodiment as defined in
claim 18 has proved to be of advantage because the stiffer and more solid material needed for the pushing-on movement is already disposed on the external face of the protective cap and it can therefore be protected against high mechanical abrasion in the region of the end wall. Furthermore, the user has an easy way of telling that an appropriate pressing force must be applied to the protective cap in the region of its center in order to fit it the optical device to be protected. - Based on an advantageous embodiment defined in
claim 19, an additional mechanical, positive connection is obtained between the layers to be joined to one another. - Also of advantage is an embodiment defined in
claim 20, because additional mechanical support is provided not only in the peripheral region, but also in the region of the center where there is the biggest relative mutual shifting between the layers, thereby enabling the overall strength to be increased. - As defined in
claim 21, additional stiffening of the protective cap can also be achieved beyond the region of the end wall, which makes it even easier to fit the protective cap on the optical device to be protected. - In the case of the embodiment defined in
claim 22, a predefined weaker region is obtained for the retaining shoulder extending out from the ocular or lens end, thereby making the snap-fitting operation significantly easier. - Another possible embodiment is defined in
claim 23 whereby a part can be obtained from a manufacturing process where the insert part for the first layer can be embedded or on-molded. In addition, however, the protective cap can also be easily adapted to different conditions of usage. - Finally, another embodiment defined in
claim 24 is of advantage because an adequate damping effect can be obtained in the peripheral region of the protective cap for the optical device to be protected. Moreover, due to the higher elastic deformability, a sufficient friction fit can be obtained to hold the protective cap on the optical device to be protected. - To provide a clearer understanding, the invention will be explained in more detail below with reference to the appended drawings.

-
FIGS. 1 to 4 illustrate a first possible embodiment of aprotective cap 1 for anoptical device 2, such as an observation device, which may be construed as an independent solution in its own right, and only a partial section of theoptical device 2 is illustrated on a simplified basis inFIG. 3 , indicated by broken lines. - The
optical device 2 has a lens end and/or ocular end, although this is not illustrated, and aprotective cap 1 may serve as a cover for both the lens end and the ocular end. Accordingly, the size of theprotective cap 1 is adapted to suit the specific dimensions of theoptical device 2. Theoptical device 2 may be a monocular or binocular telescope or field glass magnifier. However, it might also be a lens of a camera or such like, which is covered by theprotective cap 1. - The
protective cap 1 has anend wall 3, which closes off the lens or ocular end of theoptical device 2 to be covered from the outside. Disposed or arranged on the external circumference of theend wall 3 is acap casing 4. In the embodiment illustrated as an example here, thecap casing 4 is provided as a means of inserting inside the barrel of the lens and/or ocular end. To provide a better hold on theoptical device 2 and cover theoptical device 2, it is of advantage if an L-shaped retainingshoulder 5, as viewed in axial section, is provided or disposed on thecap casing 4. The L-shaped retainingshoulder 5 in turn haslegs first leg 6 is joined to theend wall 3 or to thecap casing 4 and extends radially out from it. Theleg 6 is preferably also disposed at an angle to thecap casing 4, and might also be said to be disposed in an approximately flat or parallel arrangement with respect to theend wall 3. Theother leg 7 extends approximately parallel with thecap casing 4 but is disposed radially at a distance outside of it. Since both thecap casing 4 and theother leg 7 are of an approximately tubular shape, they can be described as having an approximately cylindrical shape and a longitudinal axis extends between the two end regions of thecap casing 4 orlegs 7. - The two
legs shoulder 5 in co-operation with thecap casing 4 bound a preferably circumferentially extending tubular or cylindrical shapedhousing compartment 8. Thishousing compartment 8 is used to accommodate the complementary part of theoptical device 2 so that it can be releasably retained on it. Due to the material chosen for thecap casing 4 and thelegs shoulder 5, a sufficient adherence or retaining effect can be obtained when theprotective cap 1 is disposed in the protective or covering position on theoptical device 2 due to the elastic deformation of these components. - Known
optical devices 2 usually have a circular cross-section in the region of their lens or ocular end, and theprotective cap 1, in particular thecap casing 4, is adapted to this and is likewise round or circular and, in the case of thecap casing 4, also of a tubular shape. Theend wall 3 has acenter 9, from which thecap casing 4 is radially spaced apart. - In the embodiment illustrated as an example here, the
end wall 3 is preferably of a multi-layered design from itscenter 9 as far as thecap casing 4, and the material of afirst layer 10 has a higher modulus of elasticity and/or a higher Shore hardness A than the material of another orsecond layer 11. In this respect, however, thefirst layer 10 may form only certain regions or certain portions of theend wall 3. - Such protective covers are usually made from a rubber-like or silicone-type material with a high damping capacity so as to be able to provide sufficient damping in the event of impacts to the
optical device 2 on the one hand and on the other hand so as to sit sufficiently tightly on theoptical device 2 due to an easy ability to deform elastically, usually by a friction fit, to perform the protective function. - Accordingly, it is of advantage to opt for a modulus of elasticity for the
first layer 10 with a lower limit of 2000 MPa, in particular 5000 MPa, and an upper limit of 210000 MPa, in particular 15000 MPa. A preferred value in this respect may be between 6000 MPa and 8000 MPA, for example 7000 MPa. The test method used is that defined by standard ISO 527-1/-2 and the test temperature is 23° C. - The modulus of elasticity of the
second layer 11 is selected so that it is lower than the modulus of elasticity of thefirst layer 10. The Shore hardness A of thesecond layer 11 may be selected with a lower limit of 50 and an upper limit of 80. - The
first layer 10 which is harder or more solid and hence stiffer than thesecond layer 11 may be made from a material selected from the group comprising plastic, metal, metal alloys, word or a timber-like material, glass, ceramic, composite components. The plastic might be, for example, the material PBT-GF20 (polybutylene terephthalate) sold by the BASF company under the trade name “Ultradur®—B 4300 G4 High Speed”. Using this material, to which up to 20% glass fibers are added, enables stiff, tough and dimensionally stable parts to be manufactured. Where possible, various fibers or yarns could be embedded in any of the materials listed above. - If glass or an appropriate transparent plastic is used, the
first layer 10 may also serve as a filter element for observing the sun, for example, or as a selective laser protective filter where it is necessary to influence transmission behavior. This means that theprotective cap 1 can fulfill a dual function, in which case it will not be necessary to remove it from thedevice 2, in particular the observation device, for one specific intended application. Choosing the color of the material of thelayer 10 accordingly will open up a range of different applications. - When choosing the material for the
layer 10, however, care must also be taken to ensure that it is compatible with the material chosen for thedevice 2 to be protected, for example in order to prevent corrosion etc., between components that are in contact with one another. - The advantage of using a multi-layered design for at least the
end wall 3 is that it enables several different materials to be used in combination with one another, making it easier and simpler to adapt the strength properties of the entireprotective cap 1 starting from itscenter 9 as far as thecap casing 4 to suit different applications. For example, it is possible to design thefirst layer 10 as a separateflat insert part 12, in which case it is surrounded by thesecond layer 11 in at least certain regions and in particular is embedded in certain regions of thesecond layer 11. - In this respect, the
insert part 12 may be produced as a separate component in a separate injection casting process and then joined to the other material of the second orother layer 11, for example molded onto it, during the process of manufacturing theprotective cap 1 as a whole. This being the case, it may be said that the material of thesecond layer 11 orcap casing 4 is injected onto the material of thefirst layer 10 or insertpart 12. Alternatively, however, it would also be possible for thesecond layer 11 or theinsert part 12 made from it to be molded onto the material of thefirst layer 10 as it is being produced. Based on an expedient choice of materials for the first andsecond layer first layer 10 and the material used to form the second orother layer 11 into the injection casting mold for a so-called two-component injection casting process, either one after the other and/or together, and thus form theinsert part 12 orfirst layer 10 followed by theother layer 11. It would also be possible to reverse the production sequence. - The
insert part 12 orlayer 10 could also be made from braids, knitted materials, fleece and non-woven materials selected from different materials or combinations of materials. If chosen accordingly, it would also be possible to obtain sufficient stiffening, in particular bending resistance, in theend wall 3, and theentire insert part 12 can then also be embedded in thesecond layer 11. Due to the individual yarns or a lattice pattern, the material used to produce thesecond layer 11 will be able to pass through and thus establish a positive bond between the twolayers - The
first layer 10 or insertpart 12 made from it extends out from thecenter 9 in the direction towards thecap casing 4. It may also be only a partial region as viewed in the radial direction if the lens or ocular end of theoptical device 2 is of a circular design, e.g. ⅓ to ⅔ of the distance between thecenter 9 andcap casing 4, or alternatively may extend continuously as far as thecap casing 4 but optionally also beyond it. - It is also of advantage if the
insert part 12 also incorporates or has atubular shoulder 13 and theshoulder 13 is embedded or accommodated in thecap casing 4. Thisshoulder 13 is disposed on what is usually a disc-shapedinsert part 12 in the region of its external circumference, and theinsert part 12 formed in this manner is likewise of a cap-shaped design overall. However, theshoulder 13 may be disposed or provided on only certain regions in the circumferential or peripheral region of theinsert part 12. - As may best be seen from
FIG. 3 , theinsert part 12 is of a crown-shaped design as viewed in axial section, starting from its external circumference through to itscenter 9 on the side facing theoptical device 2 to be covered—in other words the side facing thecap casing 4. Due to the preferably circular design of theinsert part 12, it may be described as bowl-shaped or spherical. As viewed in axial section, theinsert part 12 therefore has an arcuate curvature and the camber is directed towards the side of thecap casing 4. On the side facing thesecond layer 10, theinsert part 12 has a convex curvature as viewed in axial section. - As may also be seen from
FIG. 3 , theinsert part 12 is disposed in the region of theend wall 3 on the side facing theprotective cap 1 covering theoptical device 2. The disc-shapedinsert part 12 therefore forms aninternal surface 14 of theprotective cap 1 in the region of theend wall 3, which extends continuously as far as thecap casing 4 preferably extending all the way round. - To improve the hold or molding of the other or
second layer 11 on thefirst layer 10 or insertpart 12, an orifice may be provided in at least thecenter 9 of theinsert part 12, through which the material or the material of thesecond layer 11 extends. Depending on the shape of theorifice 15, another positively fitting hold can be obtained between the twolayers end wall 3. This is of advantage if the material of thefirst layer 10 is such that it can not be permanently bonded to thesecond layer 11, for example fused or welded to it. - The
first layer 10 of theend wall 3 is predominantly formed by theinsert part 12 in this instance, which is made from one of the materials listed above or any combination of them. Thesecond layer 11 of theend wall 3,cap casing 4 and optionally the retainingshoulder 5 incorporating the twolegs main body 16. The material used to make the above-mentioned individual parts of themain body 16 may be selected from the group comprising elastomeric materials such as silicone (synthetic polymers) in particular silicone 70 Shore A or silicone caoutchouc or silicone rubber, rubber such as natural rubber or synthetic rubber, in particular nitrile rubber (NBR) or styrene-butadiene rubber (SBR), thermoplastic elastomers (TPE). The above-mentioned materials used to make themain body 16 should therefore be flexible and elastically deformable and optionally should also be such that they elastically rebound automatically. In this respect, plastics which have such properties have also proved to be of particular practical advantage. - In order for the
protective cap 1 to continue to be held on theoptical device 2 once it has been removed from the protective position on it so that it is not a loose part held in the hand, it is of advantage if theprotective cap 1 is provided with an additional, integrally connected fixingelement 18 via an elastic connectingelement 17. If themain body 16 described above is produced jointly with the connectingelement 17 and fixingelement 18 in a single manufacturing process, the same material may also be selected for all of them. - The fixing
element 18 is an annular or tubular component, which is also adapted to what is usually a round contour of the barrels. If the barrels are of a different shape, the cross-sectional shape of the fixingelement 18 may also be adapted to it in order to ensure correct orientation on theoptical device 2. By preference, however, a round design is selected because if the fixingelement 18 is sufficiently elastic, it can also be adapted to the cross-sectional shape of the barrels. The broken lines shown inFIG. 3 illustrate the position of the fixingelement 18 when fitted on theoptical device 2. - In order to make handling of the push-on and removable
protective cap 1 easier, it may have anadditional grip 19 on its external circumference. The advantage of the multi-layered, in particular two-layered, design of theend wall 3 is that themain body 16, in particular thesecond layer 11, of thecap casing 4 and retainingshoulder 5 can be made from a relatively soft and elastic material, thereby imparting adherence and impact damping properties to the part of theoptical device 2 to be protected. The additionalfirst layer 10 or theinsert part 12 made from it imparts extra stiffness to theend wall 3, so that when a pressing force is applied to theprotective cap 1 when fitting it on the barrel, theend wall 3 is not excessively deformed and theprotective cap 1 can be fitted or snap-fitted on theoptical device 2 with one hand or one finger. The stiffness of theend wall 3 is increased to the degree that thecap casing 4 can also be disposed lying inside on the barrel to be protected in the protective layer. Since the longitudinal extension or axial extension of thecap casing 4 is longer than theleg 7 in the same direction, there is an initial centering effect on the internal face of the barrel and the annular or tubular barrel is not pushed into thehousing compartment 8 until after a certain pushing-in distance. - As may also be seen by comparing
FIGS. 1 and 2 , theprotective cap 1 is provided with at least one cut-out 26 on the side of thecap casing 4 facing away from thecenter 9—in other words on itsexternal face 28—in order to make it easier to fit it on or remove it from theoptical device 2, which preferably extends as far as theleg 6 of the retainingshoulder 5. This cut-out 26 is preferably disposed in the region of thegrip 19 and may be based on a design distributed around the circumference. The purpose of the cut-out 26 is to vent and/or air the cavity bounded by the barrel andprotective cap 1. As a result, any air which might be present in this cavity can largely escape through the cut-out 26 when fitting theprotective cap 1. The same applies when removing theprotective cap 1 because air is able to flow into the cavity through the cut-out 26, thereby preventing a vacuum from being created during removal, which would otherwise produce an additional suction or adhering effect. - If the retaining
shoulder 5 sits with itsleg 7 in a tight or sealing abutment on the external face of the barrel of theoptical device 2 when theprotective cap 1 is in the fitted position, at least one other cut-out 27 may also be provided on the side of theleg 7 facing thecap casing 4 orcenter 9—in other words on the internal face. This cut-out 27 also extends in the axial direction from a terminal end face of theleg 7, preferably continuously, as far as thefirst leg 6 of the retainingshoulder 5. This being the case, most of the air which might be present in thehousing compartment 8 is also able to escape through the cut-out 27. The two cut-outs outs - In order to fix a predefined portion where the cap casing sits in contact with the barrel of the
optical device 2, at least oneprojection 29 may be provided on thecap casing 4 on the side facing away from thecenter 9—in other words on itsexternal face 28. Theprojection 29 illustrated here has a cross-section, as viewed in axial section, which more or less corresponds to an arc and extends radially out from theexternal face 28 of thecap casing 4. Theprojection 29 may be provided in certain regions only or alternatively may extend continuously around the circumference. Depending on the cross-sectional shape selected as well as the number and disposition of the projection orprojections 29 on thecap casing 4, the centering effect and/or the retaining force of theprotective cap 1 in the position fitted on theoptical device 2 can be selected and varied accordingly. It is also of advantage if the projection orprojections 29 are spaced back from anend face 30 of thecap casing 4 in the direction towards theend wall 3, and theend face 30 is disposed on the side of thecap casing 4 facing away from theend wall 3. Accordingly, theexternal face 28 through to theprojection 29 may serve as an additional centering aid or guide for theprotective cap 1 when fitting it on the barrel of theoptical device 2. Thecontinuous projection 29 may then be interrupted in the region of the cut-out 26 described above. - Due to the additional stiffness imparted to the
end wall 3 by theinsert part 12, handling may be effected in the region of thecenter 9 so that force can be transmitted or introduced into thecap casing 4 without theend wall 3 being subjected to excessive deformation if a relatively soft material is selected for thelayer 11 ormain body 16. If only a single material were used but one which had sufficient flexibility or elasticity for the retaining or adhering operation, theend wall 3 would permit high deformation when force is applied to thecenter 9 and thus make the snap-fitting operation much more difficult or even prevent the fitting operation proposed by the invention altogether. This would make it necessary to hold the wholeprotective cap 1 by its external circumference and then fit it on theoptical device 2. -
FIG. 5 illustrates another embodiment of theprotective cap 1 which may also be regarded as a solution in its own right, the same reference numbers and component names being used for parts which are the same as those in the description given with respect toFIGS. 1 to 4 above. To avoid unnecessary repetition, reference may be made to the detailed description given in connection withFIGS. 1 to 4 above. - This
protective cap 1 is also of a multi-layered design in the region of itsend wall 3 and comprises thefirst layer 10, thesecond layer 11 which is preferably joined to it, thecap casing 4 and optionally the L-shaped retainingshoulder 5 with itslegs - By contrast with the embodiment of the
protective cap 1 described above, theinsert part 12 formed by thefirst layer 10 is disposed in the region of theend wall 3 on the side facing away from theoptical device 2 to be covered in this instance. Accordingly, when theprotective cap 1 is in the position fitted on theoptical device 2 to be covered or protected, theinsert part 12 orfirst layer 10 constitutes at least a major part of the external surface of theend wall 3. To improve the adherence or connection of thefirst layer 10 to the material of thesecond layer 11, it is of advantage if at least oneprojection 20 is provided on theinsert part 12, which projects or extends into the material or the material of thesecond layer 11. By preference, theprojection 20 is disposed at thecenter 9 of theinsert part 12. It would also be possible to provide several of theprojections 20 distributed on theinsert part 12 in order to establish a positive adherence or connection to the material of thesecond layer 11 ormain body 16. - In the region of its external circumference, the
insert part 12 again has the preferablytubular shoulder 13 extending into thecap casing 4. This also imparts additional stiffness to thecap casing 4, thereby enabling a better guiding action to be obtained by thecap casing 4 during the fitting movement. - The preferably
flat insert part 12 may also have a flange extending radially out from thetubular shoulder 13 on its external circumference, which preferably extends on the external surface into the L-shaped retainingshoulder 5. In this region, a flat arrangement may be provided between the external surface of theinsert part 12 and the L-shaped retainingshoulder 5. - Irrespective of the above, however, it would also be possible to provide an arrangement whereby an
end face 22 of theflange 22 made from the material or the material of thesecond layer 11 facing away from thecenter 9 of theinsert part 12 extends in the direction towards thecenter 9, thereby ensuring that theinsert part 12 is completely embedded in its external circumferential region. - The material of the
second layer 11 in the region of theend face 22 of theflange 21 facing away from thecenter 9 may also be spaced at a distance apart therefrom. Aminimal gap 23 is therefore left free between theend face 22 and the material of the retainingshoulder 5 of themain body 16. This results in a simple and easy deformation movement of the retainingshoulder 5 in order to vary thehousing compartment 8 for the snap-fit operation. - If the
flange 21 is not provided, anend face 24 of theinsert part 12 may likewise be disposed radially at a distance apart from the material of thesecond layer 11 so that agap 23 is also formed. This again means that theinsert part 12 may extend circumferentially and thus be fully embedded at its external circumferential region. - Irrespective of the above, however, it would also be possible for the
end wall 3 to be of a three-layered design in at least certain regions, in which case it may be made from the same material as that used for themain body 16. Another option would be to use a different material. Thisadditional layer 25 is indicated by broken lines inFIG. 5 . It would therefore be possible to embed thefirst layer 10 or insertpart 12 completely in themain body 16. It would also be conceivable to opt for this variant in the case of the embodiment described with reference toFIGS. 1 to 4 . - A gap width of the
gap 23 may be formed between closely lying but not integrally formed parts and thus have a distance of from 0.0 mm up to a few tenths of a mm or bigger. -
FIG. 6 illustrates another embodiment of theprotective cap 1, which may also be construed as an independent embodiment, the same reference numbers and component names being used to denote parts that are the same as those described in connection withFIGS. 1 to 5 above. To avoid unnecessary repetition, reference may be made to the detailed description ofFIGS. 1 to 5 above. - The
protective cap 1 illustrated here has only thefirst layer 10 in the region of itsend wall 3, which in the embodiment illustrated as an example is theinsert part 12. In its circumferential region, it extends into thecap casing 4 and is preferably surrounded by the latter around its entire circumference. Accordingly, theend wall 3 is based on a design of only one layer and the material used to make thelayer 10 is a more solid and stiffer material than that of thecap casing 4. - To transmit force more effectively from the insert part to the
cap casing 4, the preferably circumferentially extendingshoulder 13 may also be provided on theinsert part 12. - The
cap casing 4 is again used for inserting in the internal face of a barrel of theoptical device 2, not illustrated. In addition to thecap casing 4, the retainingshoulder 5 with itslegs protective cap 1 easier, both thegrip 19 and the cut-outs projection 28, which usually extends around the circumference. In order to hold theprotective cap 1 on theoptical device 2, the fixingelement 18, not illustrated, may be connected via the connectingelement 17 to theprotective cap 1, in particular itsmain body 16. -
FIG. 7 illustrates another and optionally independent embodiment of theprotective cap 1, the same reference numbers and component names being used for parts that are the same as those described in connection withFIGS. 1 to 6 above. To avoid unnecessary repetition, reference may be made to the detailed description given with reference toFIGS. 1 to 6 above. - The
protective cap 1 illustrated here is also of a multi-layered design in the region of itsend wall 3 and comprises thefirst layer 10, which is designed as aseparate insert part 12. By contrast with thefirst layer 10 illustrated inFIGS. 1 to 3 , this one is approximately cruciform or star-shaped in terms of its contour. Theorifice 15 may be provided at thecenter 9 of theinsert part 12, which provides a passage for thesecond layer 11. - The
internal surface 14 of theprotective cap 1 in this instance comprises thefirst layer 10 or insertpart 12 made from it in certain regions on the one hand and the second orother layer 11. As viewed in the circumferential direction,individual arms 31 of theinsert part 12 on its external circumference may be provided with theshoulders 13 described above, which may be accommodated or embedded in thecap casing 4. - The
end wall 3 is therefore of a multi-layered design in some regions. At thecenter 9, theinsert part 12 has the highest stiffness or strength in terms of the flexing needed for fitting on theoptical device 2 as desired. In this respect, it should be pointed out that the selected shape of theinsert part 12 based on a star or cross is just one of a plurality of other possible cross-sectional shapes. -
FIGS. 8 and 9 illustrate another independent embodiment of theprotective cap 1, the same reference numbers and component names being used for parts that are the same as those described in connection withFIGS. 1 to 7 above. To avoid unnecessary repetition, reference may be made to the detailed description ofFIGS. 1 to 7 above. - In this instance, the
protective cap 1 comprises only themain body 16 and it alone, made from the material of the second orother layer 11, and the arrangement comprising thefirst layer 10 or insertpart 12 made from it is dispensed with. - In the region of its
end wall 3, theprotective cap 1 is formed by the material of thesecond layer 11, radially adjoined in the circumferential direction by thecap casing 4 and optionally the L-shaped retainingshoulder 5 with itslegs grip 19 as well as the fixingelement 18 connected via the connectingelement 17 to theprotective cap 1 may also be provided. In order to retain clarity, the cut-outs projection 28 have been omitted from the drawing. However, these components may naturally also be incorporated as described above. - To impart extra stiffness to the
end wall 3 to prevent flexing or bending, at least one but preferably several web-type ribs 32 are provided on it. As viewed radially, theribs 32 are disposed between the circumferentially extendingcap casing 4 and thus impart the desired extra stiffness. If severalsuch ribs 32 are provided on theinternal surface 14 of theprotective cap 1, in particular itsend wall 3, they may extend out from thecenter 9 in a star shape or at an angle with respect to one another. -
FIG. 10 illustrates another, optionally independent embodiment of theprotective cap 1, the same reference numbers and component names being used for parts that are the same as those described in connection withFIGS. 1 to 9 . To avoid unnecessary repetition, reference may be made to the detailed description ofFIGS. 1 to 9 above. - The
protective cap 1 illustrated here is of a multi-layered design at least in the region of itsend wall 3 and comprises thefirst layer 10, thesecond layer 11 preferably joined to it, thecap casing 4 and optionally the L-shaped retainingshoulder 5 with itslegs - In this respect, the
first layer 10 is again a separate, independent, preferably flat and approximately disc-shaped component.Ribs 33 are provided on it on the side facing theoptical device 2 and thus impart additional stiffness to thefirst layer 10. Theinsert part 12 therefore comprises the preferably disc-shapedfirst layer 10 and theribs 33 molded onto it or integrally joined to it. Theribs 33 may be arranged in the same way as described above in connection withFIGS. 8 and 9 but in this instance are joined to thefirst layer 10. - In the external circumferential region of the
insert part 12 orfirst layer 10, the preferablytubular shoulder 13 may be provided, which is accommodated by or embedded in thecap casing 4. To retain clarity and keep the drawing simple, the cut-outs projection 28 and fixing element connected via the connectingelement 17 have been omitted from the drawing. These components may naturally also be used in this instance as described above. - The embodiments illustrated as examples represent possible variants of the
protective cap 1, and it should be pointed out at this stage that the invention is not specifically limited to the variants specifically illustrated, and instead the individual variants may be used in different combinations with one another and these possible variations lie within the reach of the person skilled in this technical field given the disclosed technical teaching. Accordingly, all conceivable variants which can be obtained by combining individual details of the variants described and illustrated are possible and fall within the scope of the invention. - For the sake of good order, finally, it should be pointed out that, in order to provide a clearer understanding of the structure of the
protective cap 1, it and its constituent parts are illustrated to a certain extent out of scale and/or on an enlarged scale and/or on a reduced scale. - The objective underlying the independent inventive solutions may be found in the description.
- Above all, the individual embodiments of the subject matter illustrated in
FIGS. 1 to 4 ; 5; 6; 7; 8, 9; 10 constitute independent solutions proposed by the invention in their own right. The objectives and associated solutions proposed by the invention may be found in the detailed descriptions of these drawings.
