Description

[0001] Sliding door fittings and associated sliding door arrangement

[0002] The invention relates to a sliding door fitting, a sliding door arrangement with such a sliding door fitting and a piece of furniture with such a sliding door arrangement.

[0003] This application claims priority from German patent application DE 10 2023 003 767.2 of September 16, 2023, the contents of which are incorporated in full by reference.

[0004] Sliding door fittings can be used to slide sliding doors on furniture sideways. Sliding door fittings in which the sliding doors are moved from a front level to a rear level when opened are known from the prior art. For example, the document DE 20 2019 108 859 U 1 discloses a sliding door fitting with a guide groove and a sliding fitting in the form of plastic gliders that can be moved longitudinally and transversely within it. The sliding fitting has a spring arm that moves with the sliding door. Each of the sliding doors can be moved backwards against the spring arm.

[0005] The invention is based on the object of providing an improved sliding door fitting, in particular a sliding door fitting with the simplest possible design. A further object of the invention is to provide a sliding door assembly with such a sliding door fitting and a piece of furniture with such a sliding door assembly.

[0006] These problems are solved by the sliding door fitting, the sliding door arrangement, and the furniture of the independent patent claims. Advantageous further developments are specified in the dependent patent claims.

[0007] According to a first aspect of the invention, a sliding door fitting is designed for laterally displacing a first sliding door between a closed position and an open position and for laterally displacing a second sliding door between a closed position and an open position. The first sliding door is arranged in a front vertical plane in the closed position and in a rear vertical plane in the open position. The second sliding door is arranged in the front vertical plane both in the closed position and in the open position. The sliding door fitting has an upper guide element for guiding the first sliding door and the second sliding door at the top. The sliding door fitting has a lower guide element for guiding the first sliding door and the second sliding door at the bottom. The upper guide element and the lower guide element each have a main direction of extension.The main direction of extension can in particular be aligned along the guide element. Furthermore, the main direction of extension can be aligned along a direction of lateral displacement of the first sliding door and / or the lateral displacement of the second sliding door. The upper guide element has a first upper rail region for upper guiding of the first sliding door and a second upper rail region for upper guiding of the second sliding door. The lower guide element has a first lower rail region for lower guiding of the first sliding door and a second lower rail region for lower guiding of the second sliding door. The sliding door fitting further has a first upper sliding fitting for fastening at the top of the first sliding door and a first lower sliding fitting for fastening at the bottom of the first sliding door. The first upper sliding fitting has a spring element.The first lower sliding fitting also has a spring element. The first lower sliding fitting is mounted in the first lower rail region so that it can move both along the main direction of extension and transversely to the main direction of extension. The first upper sliding fitting is mounted in the first upper rail region so that it can move both along the main direction of extension and transversely to the main direction of extension. The first upper sliding fitting is displaceable on a partial section of the first upper rail region from a forward sliding position against the restoring force of the spring element transversely to the main direction of extension. The first lower sliding fitting is displaceable on a partial section of the first lower rail region from a forward sliding position against the restoring force of the spring element transversely to the main direction of extension. The second upper rail region and the second lower rail region each have a linear guide.The sliding door fitting further comprises a second upper sliding fitting for attachment to the top of the second sliding door and a second lower sliding fitting for attachment to the bottom of the second sliding door. The second upper sliding fitting is guided in the linear guide of the second upper rail region for displacement in the main extension direction, in particular exclusively in the main extension direction. The second lower sliding fitting is guided in the linear guide of the second lower rail region for displacement in the main extension direction, in particular exclusively in the main extension direction.

[0008] This sliding door fitting has a few, inexpensive, and lightweight parts that are neither error-prone nor complex to install. This results in a simple structure and thus an improved sliding door fitting. The fact that the second sliding door is guided essentially along the main extension direction enables a simplified design. In particular, the first sliding door can be slid behind the second sliding door. The terms "top" and "bottom" should refer in particular to opposite sides of the first sliding door and the second sliding door, respectively, for a conventionally constructed piece of furniture with vertical sliding doors, i.e. sliding doors arranged vertically within the furniture. The sliding doors can be arranged next to one another.Of course, a different spatial orientation of the furniture can also be chosen; the terms “top” and “bottom” should then continue to refer to opposite sides of the first sliding door or the second sliding door, whereby the lateral movement of the first sliding door or the second sliding door should neither take place in the direction designated as top nor in the direction designated as bottom.

[0009] The guide elements can be designed as grooves in a material of the furniture, but also as guide tracks. The material of the furniture can in particular comprise or be a wood-based material. The sliding fittings can have guided elements that are guided in or on the respective guide elements. The guide elements can be referred to as rails, for example. The guided elements can be designed as gliders or rollers, for example. In the front vertical position, the first sliding fitting can rest both at the top and bottom on a front rail edge. In the rear vertical position, the first sliding fitting can rest both at the top and bottom on a rear rail edge.

[0010] The first upper sliding fitting and the first lower sliding fitting can be structurally identical. Alternatively or additionally, the second upper sliding fitting and the second lower sliding fitting can be structurally identical. Furthermore, it can be provided that the first upper sliding fitting is symmetrical to the first lower sliding fitting and / or the second upper sliding fitting is symmetrical to the second lower sliding fitting.

[0011] In one embodiment of the sliding door fitting, when the second sliding fittings, i.e., the second upper sliding fitting and the second lower sliding fitting, are moved laterally, the first sliding fittings, i.e., the first upper sliding fitting and the first lower sliding fitting, can be moved transversely to the main direction of extension against the restoring force of the spring elements. As a result, the first sliding door moves behind the second sliding door when the second sliding door moves.

[0012] In one embodiment of the sliding door fitting, the first upper sliding fitting has two first fitting parts for longitudinally spaced attachment to the first sliding door. These can, in particular, be of identical construction. In one embodiment of the sliding door fitting, the first lower sliding fitting has two first fitting parts for longitudinally spaced attachment to the first sliding door. These can, in particular, be of identical construction. The first fitting parts each have a spring element. In particular, the first fitting parts of both the first upper sliding fitting and the first lower sliding fitting can each have a spring element. The configurations of the spring elements described below can also be provided here.It can further be provided that both the first fitting parts of the first upper sliding fitting and the first fitting parts of the first lower sliding fitting are designed identically. This can simplify the production of the sliding door fitting and, in particular, make it more cost-effective, since identical parts can be produced.

[0013] In one embodiment of the sliding door fitting, the spring element has a base body and a spring arm. The spring arm has a first spring arm end and a second spring arm end. The first spring arm end is fastened to the base body. The second spring arm end is movable from an extended position toward the base body against a spring force. In particular, the spring arm and base body can be designed as a single piece. For example, after a movement toward the base body, the spring arm can be substantially parallel to the main extension direction of the guide elements. "Substantially parallel" can mean that an angle between the main extension direction and the spring arm is a maximum of 5 to 10 degrees. Furthermore, it can be provided that in the extended position, an angle between the spring arm and the main extension direction is at least 20, in particular at least 25 degrees.

[0014] The spring arm and the base body can, for example, be made of a plastic or comprise a plastic. Alternatively, the spring arm and the base body can be made of a metal or comprise a metal, such as aluminum. In particular, the spring arm and the base body can each be an injection-molded or transfer-molded part. A combination of the materials of the spring arm and base body is also conceivable, for example, a base body made of a metal and a spring arm made of plastic.

[0015] In one embodiment of the sliding door fitting, a spring arm rolling element is arranged at the second spring arm end. The spring arm rolling element can, in particular, be a spring arm roller. Alternatively, spring arm balls or spring arm needles are also conceivable. The spring arm rolling element can reduce friction between the spring arm and the guide elements. This can result in smoother and / or quieter operation of the sliding door fitting.

[0016] In one embodiment of the sliding door fitting, a leaf spring is arranged between the base body and the spring arm. This allows for simple production of the spring element. Alternatively, another spring, such as a coil spring, can be arranged between the base body and the spring arm. Furthermore, a spring effect can also result from the arrangement of the spring arm on the base body, particularly with a one-piece design of the spring arm and base body.

[0017] In one embodiment of the sliding door fitting, the spring arm is attached to the base body by means of an axle in the base body's axle mounts. This allows for easy installation of the spring arm on the base body.

A width of the first groove is greater than a width of the second groove. Both embodiments can also be implemented simultaneously. In both cases, the rail profile can be a metallic rail profile or a rail profile made of a plastic. The width of the grooves can relate to a direction transverse to the main direction of extension. In particular, the width perpendicular to the main direction of extension can be designed as defined above.Alternatively, two rail profiles can be provided, with the first groove being arranged in one of the two rail profiles and the second groove being arranged in the other of the two rail profiles.

Furthermore, the first upper sliding roller body can have a first upper sliding roller freely rotatable about a vertical axis, with which lateral guidance can be achieved. In this case, for example, two first upper sliding rollers can also be provided.Alternatively, one of the previously described spring rollers of the first upper sliding fitting can also be used for lateral guidance. In this case, for example, only one of the first upper sliding rollers can be used for lateral guidance.

[0022] In one embodiment of the sliding door fitting, the first lower sliding fitting has at least one first lower sliding roller body, wherein the first lower sliding roller body protrudes in the direction of the first lower rail region.

In particular, when the guide elements are firmly connected to a furniture carcass, this allows for simple mounting of the first sliding door and / or the second sliding door.Tool-free assembly can mean that the first sliding door and / or the second sliding door can be attached to the guide elements without the use of tools.

[0026] In one embodiment of the sliding door fitting, the first fastening element and / or the second fastening element has a further spring element. The further spring element is arranged between a fastening point on the first sliding door or the second sliding door and one of the guide elements. A restoring force of the further spring element presses a first guided element of the first sliding fitting, i.e. the first upper sliding fitting or the first lower sliding fitting, or a second guided element of the second sliding fitting, i.e. the second upper or second lower sliding fitting, against the guide element, i.e. the upper guide element or the lower guide element.

The first sliding door 11 is arranged in the front vertical plane in the closed position and in one of the vertical planes in the open position.The second sliding door 12 is arranged in the front vertical plane both in the closed position and in the open position. The sliding door fitting 100 has an upper guide element 110 for guiding the first sliding door 11 and the second sliding door 12 at the top. The sliding door fitting has a lower guide element 120 for guiding the first sliding door 11 and the second sliding door 12 at the bottom. The upper guide element 110 and the lower guide element 120 each have a main extension direction 101. The main extension direction 101 can be aligned in particular along the guide element 110, 120. Furthermore, the main extension direction 101 can be aligned along a direction of lateral displacement of the first sliding door 11 and / or the lateral displacement of the second sliding door 12.The upper guide element 110 has a first upper rail region 111 for guiding the first sliding door 11 at the top and a second upper rail region 112 for guiding the second sliding door 12 at the top. The lower guide element 120 has a first lower rail region 121 for guiding the first sliding door 11 at the bottom and a second lower rail region 122 for guiding the second sliding door 12 at the bottom. The sliding door fitting 100 further has a first upper sliding fitting 130 for fastening at the top of the first sliding door 11 and a first lower sliding fitting 150 for fastening at the bottom of the first sliding door 11. The first upper sliding fitting 130 has at least one spring element 131. In Fig. 1, two spring elements 131 of the first upper sliding fitting 130 are optionally shown. The first lower sliding fitting 150 also has at least one spring element 151. In Fig.1, two optional spring elements 151 of the first lower sliding fitting 150 are shown. The first upper sliding fitting 130 is mounted in the first upper rail region 111 so as to be displaceable both along the main direction of extension 101 and transversely to the main direction of extension 101. The first lower sliding fitting 130 is mounted in the first lower rail region 121 so as to be displaceable both along the main direction of extension 101 and transversely to the main direction of extension 101. The first upper sliding fitting 130 is displaceable on a partial section 113 of the first upper rail region 111 from a front sliding position against the restoring force of the spring element 131 transversely to the main direction of extension 101. The first lower sliding fitting 150 is displaceable on a partial section 123 of the first lower rail region 121 from a front sliding position against the restoring force of the spring element 151 transversely to the main extension direction 101.The second upper rail section 112 and the second lower rail section 122 each have a linear guide 114, 124. The sliding door fitting further comprises a second upper sliding fitting 170 for attachment to the top of the second sliding door 12 and a second lower sliding fitting 190 for attachment to the bottom of the second sliding door 12. The second upper sliding fitting 170 is guided displaceably in the linear guide 114 of the second upper rail section 112 in the main extension direction 101, in particular exclusively in the main extension direction 101. The second lower sliding fitting 190 is guided displaceably in the linear guide 124 of the second lower rail section 122 in the main extension direction 101, in particular exclusively in the main extension direction 101.The first sliding door 11 is thus mounted so as to be displaceable both in the main extension direction 101 and transversely to the main extension direction 101 by means of the first upper sliding fitting 130 in the first upper rail regions 111 of the upper guide element 110 and by means of the first lower sliding fitting 150 in the first lower rail regions 121 of the lower guide element 120.

[0076] This sliding door fitting 100 comprises a few, cost-effective, and lightweight parts that are neither error-prone nor complex to assemble. This results in a simple structure and thus an improved sliding door fitting 100. Because the second sliding door 12 is guided essentially along the main extension direction 202, a simplified design is possible. In particular, the first sliding door 11 can be pushed behind the second sliding door 12.

[0077] The terms "top" and "bottom" should refer in particular to opposite sides of the first sliding door 11 and the second sliding door 12, respectively, for a conventionally constructed piece of furniture with vertical sliding doors 11, 12. The arrangement of the sliding doors 11, 12 and the sliding door fitting 100 in Fig. 1 corresponds to this arrangement. The sliding doors 11, 12 can be arranged side by side. Of course, a different spatial orientation of the furniture can also be chosen; the terms "top" and "bottom" should then continue to refer to opposite sides of the first sliding door 11 and the second sliding door 12, respectively, with these sides each facing the guide elements 110, 120.

[0078] The guide elements 110, 120 can be designed as grooves in a material of the furniture, in particular a wood-based material, but also as guide tracks 115, 125. The sliding fittings 130, 150, 170, 190 can have guided elements 132, 152, 172, 192 that are guided in or on the respective guide elements 110, 120. In Fig. 1, two guided elements 132, 152, 172, 192 are shown per sliding fitting 130, 150, 170, 190. However, a different number or a different number for each of the sliding fittings 130, 150, 170, 190 can also be provided. In Fig. 1, the guided elements 132, 152, 172, 192 are each slidably guided in the rail areas 111, 112, 121, 122. The guided elements 152 of the first lower sliding fitting 150 can be designed analogously to the guided elements 132 of the first upper sliding fitting 130.The guided elements 192 of the second lower sliding fitting 190 can be designed analogously to the guided elements 172 of the second upper sliding fitting 170. The guide elements 110, 120 can be referred to as rails, for example. The guided elements 132, 152, 172, 192 can be designed as sliders, as shown in Fig. 1, or alternatively as rollers. In the front vertical position, the first upper sliding fitting 130 can rest against a front rail edge 116 of the first upper rail region 111. In the front vertical position, the first lower sliding fitting 150 can rest against a front rail edge 126 of the first lower rail region 121. In the rear vertical position, the first upper sliding fitting 130 can rest against a rear rail edge 117 of the first upper rail region 111.In the rear vertical position, the first lower sliding fitting 150 can rest on a rear rail edge 117 of the first lower rail area 121.

[0079] Optionally, as shown in Fig. 1, the first sliding door 11 and the second sliding door 12 each have several cup recesses 13 and two screw holes 14 for each cup recess 13. The sliding fittings 130, 150, 170, 190 can be attached to the sliding doors 11, 12 using screws 15. For this purpose, the sliding fittings 130, 150, 170, 190 can have cups 16 that are inserted into the cup recesses 13. The screws 15 can be screwed into the screw holes 14.

[0080] Fig. 2 shows a plan view of the sliding door arrangement 10 of Fig. 1. The sliding doors 11, 12 are shown from the inside, i.e. seen from the direction of a furniture carcass. The sliding doors 11, 12 are each shown in a closed position, i.e. the sliding doors 11, 12 are closed. Fig. 3 shows a cross-section of the sliding door arrangement 10 of Fig. 2 along the section line marked AA in Fig. 2. Since the first sliding door 11 and the second sliding door 12 are both arranged in the closed position in the front vertical plane 102, the second sliding door 12 is covered by the first sliding door 11 and not visible in the illustration in Fig. 3.

[0081] Fig. 4 shows a cross-section of the sliding door arrangement 10 of Fig. 2 along the section line marked BB in Fig. 2. In particular, a lower region of the sliding door fitting 100 with the lower guide element 120, the first lower sliding fitting 150 and the second lower sliding fitting 190 is depicted. The spring element 151 of the first lower sliding fitting 150 borders here on the rear rail edge 127 of the first lower rail region 121. In the closed position, this results in the first sliding door 11 being guided on the front rail edge 126 by the guided element 152 and on the rear rail edge 127 by the spring element 151. Analogously, the spring element 131 of the first upper sliding fitting 130 can border on the rear rail edge 117 of the first upper rail region 111.Thus, in the closed position, the first sliding door 11 is guided at the front rail edge 116 by the guided element 132 and at the rear rail edge 117 by the spring element 131.

[0082] Fig. 5 shows a cross-section of the sliding door assembly 10 of Fig. 2 along the section line marked CC in Fig. 2. In particular, a lower region of the sliding door fitting 100 with the lower guide element 120, the first lower sliding fitting 150, and the second lower sliding fitting 190 is depicted.

[0083] The second sliding door 12 is guided so as to be linearly displaceable exclusively in the front vertical plane 102 of the first sliding door 11 between a closed position and an open position. The second sliding door 12 is guided so as to be displaceable exclusively in the main extension direction 101 by means of the second upper sliding fitting 170 in the second upper rail region 112 of the upper guide element 110. The second sliding door 12 is guided so as to be displaceable exclusively in the main extension direction 101 by means of the second lower sliding fitting 190 in the second lower rail region 122 of the lower guide element 120. The first and second sliding doors 11, 12 are flush with one another at the front. The first sliding door 11 is transversely displaceable from the front vertical plane backwards into the rear vertical plane in order to slide the two sliding doors 11, 12 past one another. In Fig.Figures 1 to 5 show further optional features of the sliding door fitting 100, which are explained below. These are referred to below as exemplary embodiments. In particular, the features explained below can be used individually in a sliding door fitting 100 with the properties described up to this point.

[0084] In one embodiment of the sliding door fitting 100, the first upper sliding fitting 130 is structurally identical to the first lower sliding fitting 150. In one embodiment, the second upper sliding fitting 170 is alternatively or additionally structurally identical to the second lower sliding fitting 190.

[0085] In one embodiment of the sliding door fitting 100, the first upper sliding fitting 130 is designed symmetrically to the first lower sliding fitting 150 and / or the second upper sliding fitting 170 is designed symmetrically to the second lower sliding fitting 190.

[0086] In one embodiment of the sliding door fitting 100, when the second sliding fittings 170, 190, i.e., the second upper sliding fitting 170 and the second lower sliding fitting 190, are displaced laterally, the first sliding fittings 130, 150, i.e., the first upper sliding fitting 130 and the first lower sliding fitting 150, are displaceable transversely to the main extension direction 102 against the restoring force of the spring elements 131, 151. As a result, the first sliding door 11 moves behind the second sliding door 12 when the second sliding door 12 moves.

[0087] In one embodiment of the sliding door fitting 100, the first upper sliding fitting 130 has two first fitting parts 133 for longitudinally spaced attachment to the first sliding door 11. The first fitting parts 133 can, in particular, be of identical construction. In one embodiment of the sliding door fitting 100, the first lower sliding fitting 150 has two first fitting parts 153 for longitudinally spaced attachment to the first sliding door 11. The first fitting parts 153 can, in particular, be of identical construction. The first fitting parts 133, 153 each have a spring element 131, 151. In particular, the first fitting parts 133, 153 of both the first upper sliding fitting 130 and the first lower sliding fitting 150 can each have a spring element 131, 151. A central web 134 can be arranged between the first fitting parts 133 of the first upper sliding fitting 130.A central web 154 can also be arranged between the first fitting parts 153 of the first lower sliding fitting 150. The central webs 134, 154 can increase the stability of the respective first sliding fitting 130, 150. The configurations of the spring elements 131, 151 described further below can also be provided here. Furthermore, it can be provided that both the first fitting parts 133 of the first upper sliding fitting 130 and the first fitting parts 153 of the first lower sliding fitting 150 are configured identically.

[0088] This can simplify the manufacture of the sliding door fitting 100 and, in particular, make it more cost-effective since identical parts can be produced.

[0089] In one embodiment of the sliding door fitting 100, the spring element 131, 151 comprises a base body 135, 155 and a spring arm 136, 156. The spring arm 136, 156 has a first spring arm end 137, 157 and a second spring arm end 138, 158. The first spring arm end 137, 157 is attached to the base body 135, 155. The second spring arm end 138, 158 is movable from an extended position toward the base body 135, 155 against a spring force. In particular, the spring arm 136, 156 and the base body 135, 155 can be configured as a single piece. However, as shown in Figs. 1 to 5, the spring arm 136, 156 and the base body 135, 155 each form a multi-part spring element 131, 151. For example, after a movement toward the base body 135, 155, the spring arm 136, 156 can be substantially parallel to the main extension direction 101 of the guide elements 110, 120.Essentially parallel can mean that an angle between the main extension direction 101 and the spring arm 136, 156 is a maximum of 5 to 10 degrees. Furthermore, it can be provided that in the extended position, an angle between the spring arm 136, 156 and the main extension direction 101 is at least 20, in particular at least 25 degrees.

[0090] The spring arm 136, 156 and the base body 135, 155 can, for example, be made of a plastic or comprise a plastic. In particular, the spring arm 136, 156 and the base body 135, 155 can each be an injection-molded or transfer-molded part.

[0091] In one embodiment of the sliding door fitting 100, a leaf spring 139, 159 is arranged between the base body 135, 155 and the spring arm 136, 156. The leaf spring 159 of the spring element 151 of the first lower sliding fitting 150 is particularly visible in the illustration in Fig. 5. The leaf spring 139 of the spring element 131 of the first upper sliding fitting 130 can be configured analogously. This enables simple production of the spring element 131, 151. Alternatively, another spring, for example a coil spring, can be arranged between the base body 135, 155 and the spring arm 136, 156. Furthermore, a spring effect can also result from the arrangement of the spring arm 136, 156 on the base body 135, 155, in particular in a one-piece design of 136, 156 and base body 135, 155.

[0092] In one embodiment of the sliding door fitting 100, the first upper rail region 111 is designed as a first groove 118 and the second upper rail region 112 as a second groove 119 of a rail profile 201. A width of the first groove 118 is greater than a width of the second groove 119. In one embodiment of the sliding door fitting 100, the first lower rail region 121 is designed as a first groove 128 and the second lower rail region 122 as a second groove 129 of a rail profile 211. A width of the first groove 128 is greater than a width of the second groove 129. Both embodiments can also be implemented simultaneously, as shown in Figs. 1 to 5. In both cases, the rail profile 211, 221 can be a metallic rail profile 211, 221 or a rail profile 211, 221 made of a plastic. The width of the grooves 118, 119, 128, 129 can be related to a direction transverse to the main extension direction 101.In particular, the width perpendicular to the main extension direction 101 can be configured as defined above. Alternatively, two rail profiles 211, 221 can be provided, with the first groove 118, 128 being arranged in one of the two rail profiles and the second groove 119, 129 being arranged in the other of the two rail profiles.

[0093] In one embodiment of the sliding door fitting 100, the first upper sliding fitting 130 has an undercut 141 extending along the main direction of extent 101. In one embodiment of the sliding door fitting 100, the first lower sliding fitting 150 has an undercut 161 extending along the main direction of extent 101. In particular, both the first upper sliding fitting 130 and the first lower sliding fitting 150 can have the undercut 141, 161. The undercut 141, 161 can engage behind the respective second (upper or lower) sliding door fitting 170, 190 when the first sliding door 11 and / or when the second sliding door 12 is moved, thus supporting the movement of the first sliding door 11 transversely to the main direction of extent 101.

[0094] In one embodiment of the sliding door fitting 100, the first upper sliding fitting 130 has a return movement rolling element 143 on an end face 142, which protrudes in the main extension direction 101. The return movement rolling element 143 can, if the first upper sliding fitting 130 has the already described undercut 141, end flush with the undercut 141 at the front. The return movement rolling element 143 can, in particular, be a return movement roller freely rotatable about a vertical axis, as shown in Figs. 1 to 5. In one embodiment of the sliding door fitting 100, the first lower sliding fitting 150 has a return movement rolling element 163 on an end face 162, which protrudes in the main extension direction 101. The return movement rolling element 163 can, if the first lower sliding fitting 150 has the undercut 161 already described, be flush with the undercut 161 at the front.The return movement rolling element 163 can, in particular, be a return movement roller freely rotatable about a vertical axis, as shown in Figs. 1 to 5. In particular, both the first upper sliding fitting 130 and the first lower sliding fitting 150 can each have the return movement rolling element 143, 163. In one embodiment of the sliding door fitting 100, the upper guide element 110 is designed as a single piece with the first upper rail region 111 and the second upper rail region 112, in particular in the form of a drawn metal profile or a drawn plastic profile. In one embodiment of the sliding door fitting 100, the lower guide element 120 is designed as a single piece with the first lower rail region 121 and the second lower rail region 122, in particular in the form of a drawn metal profile or a drawn plastic profile.

[0095] In one embodiment of the sliding door fitting 100, the second upper sliding fitting 170 has a rear-side projection section 174 extending longitudinally along the main extension direction 101, on which the first sliding door 11 is guided when it is located behind the second sliding door 12. In one embodiment of the sliding door fitting 100, the second lower sliding fitting 190 has a rear-side projection section 194 extending longitudinally along the main extension direction 101, on which the first sliding door 11 is guided when it is located behind the second sliding door 12. A width of the opening section 174, 194 transversely to the main extension direction 101 and a thickness of the first sliding door 12 or the second sliding door 12 can be matched to a width of the first rail region 111, 112 transversely to the main extension direction 101.The opening section 174, 194 can support a movement of the first sliding door 12 from the first vertical plane 102 into the second vertical plane.

[0096] In one embodiment of the sliding door fitting 100, the projection section 174, 194 is arranged within the first upper rail region 111 or the first lower rail region 121. The projection section 174, 194 reduces the rail width of the first upper rail region 111 available for the first upper sliding fitting 130 or the rail width of the first lower rail region 121 available for the first lower sliding fitting 150.

[0097] In one embodiment of the sliding door fitting 100, the projection section 174, 194 is designed such that an available rail width of the first upper rail region 111 or the first lower rail region 121 is reduced such that the first sliding door 12 can be moved linearly behind the second sliding door 12. The projection section 174, 194 thus provides a linear guide for the first sliding door 11, provided it is arranged behind the second sliding door 12.

[0098] In one embodiment of the sliding door fitting 100, the second upper sliding fitting 150 has two second fitting parts 153 for longitudinally spaced attachment to the second sliding door 12 and, between them, a center piece 175 connected to the two second fitting parts 173 and / or to the second sliding door 12. The center piece 175 forms, in particular together with the second fitting parts 173, the opening section 174. The second fitting parts 173 can, in particular, be identical to one another.

[0099] In one embodiment of the sliding door fitting 100, the second lower sliding fitting 190 has two second fitting parts 193 for longitudinally spaced attachment to the second sliding door 12 and, between them, a center piece 195 connected to the two second fitting parts 193 and / or to the second sliding door 12. The center piece 195 forms, in particular together with the second fitting parts 193, the opening section 194. The second fitting parts 193 can, in particular, be identical.

[0100] In one embodiment of the sliding door fitting 100, the second upper sliding fitting 170 and / or the second lower sliding fitting 190 has a rearwardly inclined projection 176, 196 at one end, which runs obliquely to the main extension direction 101 and merges rearwardly into the projection section 174, 194. This simplifies movement of the first sliding door 11 behind the second sliding door 12.

[0101] In one embodiment of the sliding door fitting 100, a projection roller 178, 198, in particular a projection roller freely rotatable about a vertical axis, is arranged in a transition area 177, 197 between the projection slope 176, 196 and the projection section 174, 194. This further simplifies the movement of the first sliding door 11 behind the second sliding door 12. Furthermore, the projection roller 178, 198 can assist in lateral guidance of the first sliding door 11.

[0102] In one embodiment of the sliding door fitting 100, the upper guide element 110 has two stop elements 212 at its ends. The stop elements 212 can be inserted into rail areas 111, 112 and, in particular, can be positively connected to the rail areas 111, 112. Alternatively or additionally, it can be provided that the stop elements 212 can be mounted on a furniture body, for example, by means of a screw connection. For this purpose, the stop elements 212 shown in Figs. 1 to 5 have holes.

[0103] In one embodiment of the sliding door fitting 100, the lower guide element 120 has two stop elements 222 at its ends. The stop elements 222 can be inserted into rail areas 121, 122 and, in particular, can be positively connected to the rail areas 121, 122. Alternatively or additionally, it can be provided that the stop elements 222 can be mounted on a furniture body, for example, by means of a screw connection. For this purpose, the stop elements 222 shown in Figs. 1 to 5 have holes.

[0104] Fig. 6 shows the sliding door arrangement of Figs. 1 to 5 after the start of a movement of the first sliding door 11 from the closed position towards the open position. Fig. 7 shows the sliding door arrangement of Fig. 6 at the section line marked DD in Fig. 6. Fig. 8 shows the sliding door arrangement of Fig. 6 at the section line marked EE in Fig. 6. Fig. 9 shows the sliding door arrangement of Fig. 6 at the section line marked FF in Fig. 6. The return movement rolling elements 143, 163 can roll on the respective projection bevels 176, 196 and thus assist in opening the first sliding door 11.

[0105] 1 to 9 after a further movement of the first sliding door 11 from the closed position towards the open position. Fig. 11 shows the sliding door arrangement of Fig. 10 at the section line marked GG in Fig. 10. Fig. 12 shows the sliding door arrangement of Fig. 10 at the section line marked HH in Fig. 10. Fig. 13 shows the sliding door arrangement of Fig. 10 at the section line marked II in Fig. 10. After the further opening of the first sliding door 11, it is arranged in the rear vertical plane 103. The first sliding door 11 is therefore arranged behind the second sliding door 12. The first sliding door 11 is arranged between the opening sections 174, 194 of the second sliding fittings 170, 190.

[0106] 1 to 5 after the second sliding door 12 has begun to move from the closed position towards the open position. Fig. 15 shows the sliding door arrangement of Fig. 14 at the section line marked JJ in Fig. 14. Fig. 16 shows the sliding door arrangement of Fig. 14 at the section line marked KK in Fig. 14. Fig. 17 shows the sliding door arrangement of Fig. 14 at the section line marked LL in Fig. 14. If the second sliding door 12 is moved towards the open position, the first sliding door 11 performs an opening movement analogous to that shown in Figs. 6 to 9, during which the return movement rolling elements 143, 163 roll along the opening slopes 176, 196 and the first sliding door 11 is thus moved from the front vertical plane 102 towards the rear vertical plane 103. If the second sliding door 12 is now moved further towards the open position, the result is the position shown in Fig.14 to 17, in which the first sliding door 11 is arranged completely behind the second sliding door 12 and in which the first sliding door 11 is arranged between the display sections 174, 194 of the second sliding fittings 170, 190.

[0107] Regardless of whether the first sliding door 11 or the second sliding door 12 is moved, the first sliding door 11 moves behind the second sliding door 12. This occurs in particular due to the linear guide of the second upper rail area 112 and the second lower rail area 122 in combination with the spring elements 131, 151 of the first sliding fittings 130, 150.

[0108] Fig. 18 shows an isometric view of a first fitting part 153 of the first lower sliding fitting 150 with further optional features. The spring arm 156 is attached to the base body 155 by means of an axle 164 in axle receptacles 165 of the base body 155. This enables easy assembly of the spring arm 156 to the base body 155. The first fitting parts 133 of the first upper sliding fitting 130 can be designed analogously. The base body 155 can, as shown in Fig. 18, have at least two axle receptacles 165, as does the base body 135. This enables the spring arm 136, 156 to be fastened on both sides of the respective base body 135, 155.
