Description

Combin~ion Spec'acles Description The invention pertains to combination spectacles that comprise a spectacle ~rame and an attachment that repre6ents an exchangeable spectacle front and is attached to the frame in a separable manner. It furthermore pertains to the individual components of the combination spectacles, which means inventive developments of the spectaale frame a~ well as ~he attachment.
Conventional sunglass attachments for spectacles have a frame that serves as a receptacle for the tinted lQnses, and resilient hooks that are arranged on the frame and encompass the spectacle frame when the sunglass attachment is affixed.
~owever, this particular attachment has the disadvantage that the hooks can damage the spectacle ~rame or the glasses framed therein when the attachment is affixed. It is furthermore possible that the sharp edges of the hooks can in~ure the eye area. The hooks encompassing the spectacle frame are usually clearly visiblQ and thus undesired for aesthetic reasons.
~ ritish Patent No. 2 184 864 A introduced an attachment with face components for a spectacle frame, whereby the mounting elements are constructed as clip conneotors according to a pin~bore aonneation. Different expansions of the components aonnected with each other cannot be equalized in this particular instance, so that the material selection is very limited. These difficulties are even supplemented in that the connecting elements must be positioned within very narrow tolerances and that push-button connections quickly lose the required stability because of the frequent exchange of the attachment.

British Patent No. 777 004 introduced a face component for the eye ara of a spectacle frame with two pin/bore connections, whereby each eye arc has a bore with a widened end section and a circular hole into which pins with thickened head portions attached to the rear side of the corresponding face component penetrate; the connection is secured by a swivel hook which engages behind the head portion of the pin that penetrates through the circular hole. This known connection is very demanding as far as the manufacture is concerned and also very diffiault to activate. In addition to this, two face components are required for one spectacle frame.
U.S. Patent No. 4 812 031 introduced a different attachment which extends over the entire frontal width of the spectacle frame, whereby only one connection in the area of the bridge is provided that is constructed as a snap-in connection with longitudinal snap-in elements extending in the direction of the bridge that are attached from the front. The snap-in connection simultaneously serves as a hinge that allows a swivel movement of the attachment around a horizontal axis. This known attachment can be very practical for the requirements of a hunter; however, it is very unsuitable as a stylish element since it must be constructed relatively massive in order to obtain the required stability.
The invention is based on the objective to create aesthetically attractive combination spectacles with an invisible connection between the spectacle frame and an attachment. The exchange of the attachment with a different attachment should be as easy and quickly as possible.

According to the invention, this objective is attained with a spectacle ~rame that comprises at lea~t one crosspieae with no~epads and two shafts, whereby the crosspiece is provided with one cavity each in its front near the ends which are suitable to serve as receptacles ~or a protection on the attachment such that projection and cavity form a snap-in connection. The cavity is slightly longer in longitudinal direction of the crosspiece than the projections engaging therein. The snap-in connection that affixes the attachment to the spectacle frame is not only invisible; the attachment can furthermore tightly adjoin the spectacle frame, which means that a gap between the two components is avoided. The snap-in connection between the attachment and the spectacle frame furthermore prov~des the possibility of a simple removal or mounting of the attachment, ~o that the user can change the appearance of his spectacles without much effort and within the shortest possible time, for example, adapt his spectacles to his clothing or his surroundings.
The fact that the cavities are longer in the longitudinal direction of the crosspiece than the projections provides an ideal prerequisite for an equalization of the different expansion rates of the at~achment and the spectacle frame. The attachment can exactly adapt to the curvature of the spectacle frames. The most euitable, which means the most different, materials can be utilized ~or both components since neither tension nor warping o~
the components connected with each other can occur because of the ensured expansion equalization. Such an expansion equalization should in particular, be provided at those locations where the spectacle frame and the attachment consists of different plastic materials that react differently to fluctuations in humidity.

According to the invention, this objective is attained with a spectacle ~rame that comprises at lea~t one crosspieae with no~epads and two shafts, whereby the crosspiece is provided with one cavity each in its front near the ends which are suitable to serve as receptacles ~or a protection on the attachment such that projection and cavity form a snap-in connection. The cavity is slightly longer in longitudinal direction of the crosspiece than the projections engaging therein.

The attachment preferably has tinted su~glass lenses. The speataale frame i6 either constructed as a support fra~e with corrective lenses (corrective spectacles~ arranged within the lens openings, or constructed as a support frame depending on whether an optical correction is required or not. The support frame preferably consists of a metal, while the lens openings are manufactured from a plastic material.
If the snap-in mechanism utilized is provided with a resilient element, this element can be either arranged on the projections or in the cavities. In particular, resilient tabs, claws and similar elements can represent a component of the projeations themselves, or be arranged in the cavities.
If a spectacle frame is utilized as a corrective frame with optical lenses, the spectacle frame may also be worn without the attaohment, whereby the cavities can be covered by the corresponding caps and thus be made invisible.
A particularly advantageous construction of the snap-in connection consists of the fact that the cavities consist of bores that extend in the longitudinal direction of the cros~piece and end towards the center of the spectacles with a widened portion to engage with the projections that have a narrow neck portion and a thicker head portion. The cavities consist in this particular instance of bores with an expansion on the end, whereby the dimensions of the bores are such that the thicker head portion can penetrate through the expansion, but not through the narrow area of each bore. With a rigid support frame and a flexible attachment, the mounting of the same is executed such that, at first, a pin is inserted through the corresponding bore, whereafter the attachment is somewhat stretched in the direction ' :, ~ G~
of the facial curvature and both pins are moved towards each other, so that the second pin can be inserted into the assigned bore. The attachment subsequently returns into its stretched position and the head portions of the pins are engaged.
The previously described structure of the snap-in connection is particularly insensitive to the frequently occurring widening of the spectacle frame during daily use since the projections can assume a position within the bores that is displaced towards the center without separating the snap-in conneation.
The spectacle frame can be constructed as a corrective frame that serves as a receptacle for optical lenses, in particular, by providing plastic lens openings on the support frame into which the optical lenses are inserted. The spectacle frame can, in the same manner, be constructed as a support frame that is open towards the bottom if it solely serves the purpose of a receptacle ~or the attachment and not serve as a receptacle for optical lenses. In this particular instance, the upper frame section solely connects the bridge of the support frame with the endpiece onto wh-ich the pins are attached in a pivoting manner.
If the attachment has tinted lenses, the design of the spectacle frame as a support frame makes it possible to manufacture a number of sunglasses oE very different designs by combining a support frame with different attachments. The spectacle frame can be designed in a transparent manner so it does not limit the aesthetic combination possibilities to a certain color of the spectacle frame; it can, for example, consist of a polycarbonate or a polyethersulfonate. The manufacture of the support frame consisting of metal is particularly practical in regard to , -6- '~ 3 2 '~ Q ~
manufacturing technology, and it can also be de~igned to be very thin.
The front side o~ the attachment has, in a preferred example, a laminated film which allows the manufacture of different attachment designs in the simplest manner. The element of the front side of the spectacles having the laminate is preferably manufactured from cellulose acetate.
The invention is, in the following, described in detail with the aid of the figures. They show:
Figure 1 a front view of a combination spectacle according to the invention representing an example of-a spectacle frame designed for corrective lenses, Figure 2 a front view of a combination spectacle according to the invention with a spectacle ~rame constructed as a support frame, Figure 3 a section along the line III-III in Figures 1 and 2 in a very enlarged representation, Figure 4 a rear view of an attachment for the combination spectacles according to the invention, Figure 5 a section through the attachment along the line V-V in Figure 4 in strongly enlarged representation, Figure 6 a front view of a further support frame accordingto the invention, Figure 7 a front view of a further corrective frame according to the invention, Figure 8 a rear view of an attachment to be mounted onto a support frame or corrective frame according to Figures 6 and 7, and . ~ .
Figure 9 a side view of the attachment according to Figure 8.
The spectacle frame according to Figure 1 consists conventionally of a crosspiece (1) and shafts (not shown) that are attached to the endpieces (2) of the crosspiece by means of hinges. The spectacle frame carries optical lenses (3).
Figure 2 shows that the crosspiace of the speataole frame is aonstructed as a support frame that is open towards the bottom.
It comprises a nosepad (4) and frame sections ~6) arranged on both sides of the bridge (5) which end in endpieoes (2). Optiaal lenses as they are inserted into the corrective frame according to Figure 1 are not provided on the support frame according to Figure 2.
The endpieces (2) oE the corrective ~rame according to Figure 1 as well as the support frame according to Figure 2 have rectangular cavities (7) on their front side if viewed from the top (Figures 1 and 2), whereby these rectangular cavities represent a component of the snap-in connection between the corresponding spectacle frame and an attachment affixed onto the same. Two resilient claws (8) are provided within the cavities (7) aacordlng to Figures 1 to 3. These claws extend in the longitudinal direction and are horizontally aligned parallel to each other. Each of the pair of the claws (8) has a projection (9) that protrudes towards the inside, which means that both projections (9) of a pair of claws are directed against each other. A hollow space (10) is formed between the claws (8) which serves as a receptacle for the projection arranged on the attachment, whereby the projections (9) of the claws engage into " .

corresponding receptacles provided on the projections as shown in Figure 5 and described as later in the text.
Figure 4 shows an attachment for spectacle frames according to Figures 1 to 3 from a rear top view, which means that Figure 4 shows the side of the attachment that faces the spectacle frame.
The attachment consists of a spectacle front (11) into which a sun protection lens (12) is inserted. Projections (13) are arrang~d in both outer corners of the spectacle front in accordance with the endpieces of the spectacle frame according to Figures 1 and 2, whereby these projections engage into the cavities (7) of the spectacle frame according to Figures 1-and 2 and thus together represent a snap-in connection. According to Figure 5, which shows a vertical section through the spectacle front according to Figure 4 in the area of the projection (13) (line V-V), the same is constructed as a horizontally extending, longitudinal pin (14~. It has a head portion (15) and two receptacles (16) constructed as undercuts into which the projections (9) of the claws (8) according to Figures 1 to 3 engage if the attachment is affixed onto the spectacle frame.
The head portion (15) of the pin (14) has two slanted portions ~17) that spread both claws (8) at the beginning of the mountlng process of the attachment onto the spectacle frame, so that the same can slide over the head portion oE the pin.
The horizontal extent (B) of the cavities (7) in the spectacle frame are slightly larger than the transverse extent (b) of the projections (13) of the attachments. This effects that the attachment is fixed onto the corresponding spectacle frame without tension if both parts expand to a different extent by different heat and/or humidity influence onto the different .

The ~pectaale frame according to Figure 6 is constructed as a support frame that is open towards the bottom. It has a nosepad (4) and frame sections (6) arranged on both sides of the bridge ~5) which end in endpieces (2). Both endpieces have a bore (18) that is aligned horizontally. Each bore has a circular widening (19) towards the center of the support frame whose diameter is larger than the clear width of the longitudinal bore in the narrow section (20).
The spectacle frame accordina to Figure 7 i5 constructed as a corrective frame. It comprises the support frame according to Figure 6 and two lens openings (21) that serve as a receptacle for the optical lenses (3). The lens openings (21) consist of plastic; their attachment to the support frame manufaatured from metal is executed according to the state of technology.
The attachment according to Figures 8 and 9 consists of a spectacle front (11) into which a sun protection lens (12) i8 inserted. Pins (22) are arranged in both outer corners of the spectacle front in accordance with the endpieces of the spectacle frames according to Figures 6 and 7, whereby these pins protrude towards the rear from the spectacle front. Each pin has a neck portion (23) and a head portion (24). The diameter of the head portion (24) is slightly smaller than the diameter of the widening (19) of the assigned bore (18) of the support frame; the diameter of the neck portion (23) of each pin (22) is slightly smaller than the clear width of the narrow section (20) of the bore (18). The distance o~ both pins (22) of the attachment to each other in a tension-free condition corresponds with the .
