Description

Technical Field

[0001] The present invention relates to a sunroof structure for vehicles, comprising a sunroof portion disposed on the roof of a vehicle and a first frame member and a second frame member arranged in a cross shape relative to the roof. Background Technology

[0002] Various sunroof structures for vehicles have been proposed in this regard. For example, the vehicle roof frame structure described in Japanese Patent Application Publication No. 2012-40999 includes a sunroof unit (sunroof section) that is rectangular in plan view and roof side rails (first frame members) that extend in the longitudinal direction at both ends in the vehicle width direction. Furthermore, the sunroof unit is connected to each roof side rail by brackets respectively provided at its four corners. Additionally, in the panel support mechanism for a sunroof device described in Japanese Patent Application Publication No. 2004-161104, a generally rectangular internal frame supporting the sunroof panel is fixed to a roof reinforcement member (second frame member) provided on the lower surface of the roof panel and extending in the vehicle width direction via a bracket provided at its front. Summary of the Invention

[0003] However, in the aforementioned structures, from the viewpoint of ensuring vehicle NV performance (quietness, etc.), it is desirable for the sunroof to be designed to prevent resonance with the vehicle body's vibrations. That is, vibrations from the road surface, engine, etc., during driving are transmitted to the sunroof through the pillars constituting the vehicle body. At this time, the sunroof's swaying, resonating with the vehicle body's vibrations, causes the surrounding roof panels to vibrate, sometimes resulting in unexpected sounds (noise, etc.). While it is possible to install a mass damper in the sunroof to suppress resonance, this inevitably increases the vehicle's weight. The present invention addresses these issues, and the problem it aims to solve is to suppress the increase in vehicle weight and suppress resonance in the sunroof.

[0004] means for solving problems

[0005] As a means of solving the above-mentioned problems, the sunroof structure for vehicles of the first invention includes a sunroof portion disposed on the roof of the vehicle, a first frame member extending in the longitudinal direction of the roof, and a second frame member extending in the cross direction of the roof intersecting with the first frame member. In this structure, it is desirable to suppress the increase in vehicle weight and suppress resonance of the sunroof portion. Therefore, in the sunroof structure of the present invention, an axle connecting member is provided, which connects the sunroof portion to either the first frame member or the second frame member on an imaginary axis passing through the center of gravity of the sunroof portion; and a connecting member, which connects the sunroof portion to either the first frame member or the second frame member at a position different from the axle connecting member. In the present invention, the rigidity of the connecting member is adjusted so that the side of the connecting member without the sunroof portion vibrates up and down with the axle connecting member as a fulcrum, thereby suppressing resonance. Moreover, in the sunroof structure of the present invention, since resonance is suppressed by utilizing the vibration of the sunroof portion, there is no need to separately provide a mass damper, thus greatly suppressing the increase in vehicle weight.

[0006] The second invention relates to a sunroof structure for vehicles. Based on the first invention, when the sunroof is divided into one side and another side by imaginary axes intersecting the center of gravity of the sunroof section, with the roof as a reference, a connecting member is provided at least one of the following locations: the intersection of the sunroof section with the other imaginary axes, a location on one side of the intersection, and a location on the other side of the intersection. In this invention, by providing multiple or single connecting members at desired positions based on other imaginary axes, the side of the sunroof section without connecting members can vibrate more reliably.

[0007] The third invention's sunroof structure for vehicles, based on the sunroof structures of the first or second invention, uses a top-down view of the vehicle roof as a reference. The connecting member is only located on the side separated from the imaginary axis, and the other side, located on the opposite side without a connecting member, is fixed to a first or second frame member. In this invention, the other side of the sunroof structure without a connecting member is reinforced by being fixed to the first or second frame member, thus creating a structure that helps ensure installability relative to the vehicle roof.

[0008] The sunroof structure for vehicles of the fourth invention is based on any one of the sunroof structures for vehicles in the first to third inventions, wherein the rigidity of the axle connecting member is higher than the rigidity of the connecting member. In this invention, by making the axle connecting member, which serves as a fulcrum, highly rigid, the installability (support) of the sunroof section can be more reliably ensured, and the side of the sunroof section without the connecting member is more likely to vibrate.

[0009] Invention Effects

[0010] According to the first invention of the present invention, the increase in vehicle weight can be suppressed, and the resonance of the sunroof section can be suppressed. Furthermore, according to the second invention, the resonance of the sunroof section can be suppressed more reliably. Furthermore, according to the third invention, it forms a structure that helps ensure installation relative to the vehicle roof. Moreover, according to the fourth invention, the installation of the sunroof section can be ensured, and the resonance of the sunroof section can be suppressed more reliably.

[0019] The following is for reference Figures 1-8 The method for implementing the present invention will be described. In each figure, arrow lines indicating the front-rear, left-right, and up-down directions of the vehicle (roof) are appropriately illustrated, with the left-right direction corresponding to the vehicle width direction. Additionally... Figures 4-7 For convenience, the main structure of the sunroof for the vehicle is shown in the illustration, while the illustrations of other components are omitted.

[0020] [Overview of the vehicle's roof]

[0021] Before explaining the sunroof structure SM for vehicles, let's first discuss... Figure 1 as well as Figure 2The outline of the roof 3 of the vehicle 2 shown is described below. The roof of the vehicle 2 has a rectangular roof panel 4 with a front-to-rear length, roof side rails 5a and 5b extending along the front-to-rear direction on both sides in the vehicle width direction, and multiple roof reinforcements 6 to 10 extending along the vehicle width direction. The roof panel 4 curves slowly upwards towards the rear, and its two end edges in the vehicle width direction are fixed to the roof side rails 5a and 5b. Furthermore, the roof side rails 5a and 5b are supported by pillars (12, 13, 14) that constitute the front, rear, left, right, and central portions of the vehicle body 11. Figure 1 (For simplicity, only the pillar on the left side of the vehicle is shown in the illustration.) Figure 4 As shown, the inner panel 51 and the outer panel 52 are fixed to their respective left and right flanges 53 and 54, thereby forming a hollow, closed section for each roof side rail 5a, etc. Furthermore, on the inner side of each roof side rail 5a, etc., ( Figure 4 The flange 54 on the left side overlaps and is fixed to the width direction end of the roof panel 4 (right end in the figure).

[0022] in addition, Figure 1 as well as Figure 2 The multiple roof reinforcement members 6-10 shown are beam-like structures that support the roof panel 4 from below, spanning between the left and right roof side rails 5a and 5b. Furthermore, multiple roof reinforcement members (5 in each figure) are provided at appropriate intervals on the roof 3 of the vehicle 2 in the longitudinal direction. Specifically, a pair of front roof reinforcement members 6 and 7 are provided at the front of the roof 3, and a pair of rear roof reinforcement members 8 and 9 are provided at the rear of the roof 3. Additionally, a rear roof reinforcement member 10 is provided at the rear end of the roof 3. The long side ends (both ends in the vehicle width direction) of each roof reinforcement member 6-10 are fixed together with the roof panel 4 to the left and right roof side rails 5a and 5b. The short side ends (both ends in the longitudinal direction) of each roof reinforcement member 6-10 are fixed to the lower surface of the roof panel 4. Figure 6 As shown, for example, the front rear roof reinforcement 8 is formed into a groove with a roughly U-shaped cross-section. The front and rear ends of the opening of the groove are bent to form roughly flat front and rear flanges 81 and 82. The front rear roof reinforcement 8 is fixed to the roof panel 4 through the flanges 81 and 82.

[0023] Additionally, refer to Figure 1 as well as Figure 2At the front of the roof panel 4, within the area enclosed by the left and right roof side rails 5a and 5b and the front and rear roof reinforcements 6 and 7, a rectangular front opening 3a with a left-right elongation is provided. A sunroof 20 is provided in this front opening 3a of the roof panel 4. Furthermore, at the rear of the roof panel 4, within the area enclosed by the left and right roof side rails 5a and 5b and the front and rear roof reinforcements 8 and 9, a rectangular rear opening 3b with a left-right elongation is provided. Moreover, the rear opening 3b of the roof panel 4 is larger than the front opening 3a and includes the rear sunroof 30, which will be described later.

[0024] [Sunroof Structure for Vehicles]

[0025] Moreover, such as Figures 1-3 As shown, the vehicle sunroof structure SM comprises the aforementioned rear sunroof portion 30, left and right roof side rails 5a and 5b, and a front rear roof reinforcement member 8. Specifically, the left and right roof side rails 5a and 5b correspond to the first frame components of this invention, and the front rear roof reinforcement member 8 corresponds to the second frame components of this invention. Furthermore, the rear sunroof portion 30 corresponds to the sunroof portion of this invention and is connected to the left and right roof side rails 5a and 5b and the front rear roof reinforcement member 8 via various connecting members 41 to 44 described later. Moreover, in the vehicle sunroof structure SM with the above structure, consideration is given to minimizing the increase in the weight of the vehicle 2 and preventing the rear sunroof portion 30 from resonating with the vehicle body. Therefore, in this embodiment, the weight increase of the vehicle 2 and the resonance of the rear sunroof portion 30 are suppressed by utilizing the axle connecting members 41 and 42 and connecting members 43 and 44 described later. The various structures of the vehicle sunroof structure SM will be described in detail below.

[0026] [Rear sunroof section (sunroof section)]

[0027] like Figure 2 as well as Figure 3 As shown, by fixing the rectangular roof glass 31 (which is longer on the left and right sides) and the opening reinforcement 33 (described later) to the receiving part 32 of the rear opening 3b, a structure is formed. Figure 1 The rear sunroof section 30 is shown. Here, as... Figures 4-6 As shown, the receiving portion 32 of the rear opening 3b is a portion in which the inner edge of the rear opening 3b is stepped down one level around its entire circumference, forming a space for the roof glass 31 to be inserted. Furthermore, as... Figure 5 As shown, the roof glass 31 is fixed to the bearing portion 32 with adhesive 321 at its outer edge and is arranged on the same side as the roof panel 4. In addition, a sealing strip 322 is provided between the roof glass 31 and the rear opening 3b (bearing portion 32) to seal the gap between them.

[0028] In addition, such as Figures 3-6As shown, a plate-shaped opening reinforcement 33, fixed to the lower surface of the bearing portion 32 of the roof panel 4, is provided around the periphery of the rear sunroof portion 30. Figure 3 As shown, the right side frame portion 311 and left side frame portion 312 extending in the front-rear direction, and the front side frame portion 313 and rear side frame portion 314 extending in the vehicle width direction are formed into rectangles, thereby constituting the opening reinforcement 33. Furthermore, the left side frame portion 312 located on the left side of the rear sunroof portion 30 is fixed to the left side bearing portion 32 and extends outward (left side of the figure), while the right side frame portion 311 located on the right side also extends outward (right side of the figure) while fixed to the right side bearing portion 32. Additionally, as... Figure 6 As shown, the front frame portion 313 located at the front of the rear sunroof portion 30 extends outward (forward) with the front support portion 32 fixed to it, and the rear frame portion 314 located at the rear also extends outward (rear) with the rear support portion 32 fixed to it. In this way, the roof glass 31 and the opening reinforcement 33 of the rear sunroof portion 30 are fixed to the support portion 32, and the rear sunroof portion 30 is installed on the roof 3 in a manner that is integrated with the roof panel 4.

[0029] [Shaft-mounted connecting components]

[0030] and, Figure 3 The rear sunroof 30 shown is connected to the left and right roof side rails 5a and 5b (first frame members) via left and right on-axis connecting members 41 and 42. These left and right on-axis connecting members 41 and 42 are positioned at the center of gravity 300 of the rear sunroof 30. In this embodiment, an imaginary axis VL1 is assumed to extend along the vehicle width direction (left-right direction) through the center of gravity 300 of the rear sunroof 30. Furthermore, the left and right on-axis connecting members 41 (42) arranged on the imaginary axis VL1 are horizontally mounted across the rear sunroof 30 and the corresponding roof side rails 5a (5b) and fixed in place. In this way, the center of gravity 300 of the rear sunroof 30 is supported by each on-axis connecting member 41 and 42, and the rear sunroof 30 can be connected to the left and right roof side rails 5a and 5b (first frame members).

[0031] in, Figure 3 The right-hand axle connecting member 41 and the left-hand axle connecting member 42, besides being symmetrical, have substantially the same structure. The right-hand axle connecting member 41 is mounted transversely on the aforementioned imaginary axis VL1, between the rear sunroof section 30 and the right-hand roof side rail 5a, and is fixed therein. (Refer to...) Figure 3 as well as Figure 4 The right-side axle connecting member 41 gradually slopes downwards towards the outer side in the vehicle width direction (right side of the figure), and outwardly extending peripheral flange portions 411 are formed at the front, right, and rear edges of the axle connecting member 41. Furthermore, in the right-side axle connecting member 41, as... Figure 4As shown, the left peripheral flange portion 411 overlaps and is fixed to the right frame portion 311 of the opening reinforcement 33. Furthermore, the left peripheral flange portion 411 overlaps and is fixed to the inner panel 51 of the right roof side rail 5a. Moreover, Figure 3 The left-side axle connecting component 42, shown, is also horizontally mounted and fixed between the left-side frame portion 312 of the rear sunroof portion 30 and the left-side roof side rail 5b in a manner symmetrical to the right-side axle connecting component 41. Figure 3 For convenience, the reference numerals for parts common to the right-side shaft connecting part 41 in the left-side shaft connecting part 42 are omitted.

[0032] Here, from the perspective of ensuring the installation (support) of the rear sunroof section 30 relative to the roof 3, it is hoped that... Figure 3 The connecting components 41 and 42 on the left and right shafts shown are more rigid than the connecting components 43 and 44 described later. For example, methods to improve the rigidity of the connecting components 41 and 42 on each shaft can include relatively increasing the dimension in the width direction (front-back direction in the figure) orthogonal to the crossbeam direction, or using a material with higher rigidity. Additionally, refer to... Figure 3 as well as Figure 7 For example, by forming the connecting part 41 on the right side of the shaft into a box shape that protrudes downward, or by providing a reinforced structure such as a bead-shaped recess 412, the rigidity can be improved structurally.

[0033] [Connecting Components]

[0034] in addition, Figure 3 The rear sunroof 30 shown is connected to the front rear roof reinforcement 8 (second frame member) via multiple or a single connecting member (43, 44). These connecting members (43, 44) are positioned differently from the connecting members 41, 42 on each axle to generate vibrations in the rear sunroof 30, which will be described later. Here, when determining the placement of the connecting members, [the following is considered]. Figure 8 Based on the top view of the roof 3 shown, assume another imaginary axis VL2 extending along the front-rear direction (intersecting direction) through the center of gravity 300 of the rear sunroof 30. Next, using the other imaginary axis VL2 as a boundary, the rear sunroof 30 is divided into a right side 301 and a left side 302 (one side and the other side). Then, connecting members can be provided at least one of the following locations: the intersection X1 of the rear sunroof 30 and the other imaginary axis VL2, the right side X2 located to the right of the intersection X1, and the left side X3 located to the left of the intersection X1. At this time, by setting the other imaginary axis VL2 to be orthogonal to the imaginary axis VL1, the connecting members configured based on this other imaginary axis VL2 can be configured extremely far away from the connecting members 41, 42 on each axis. Therefore, in this embodiment, as... Figure 3As shown, the rear sunroof 30 is connected to the front rear roof reinforcement 8 by means of the connecting member 43 located on the right front side of the right part X2 and the connecting member 44 located on the left front side of the left part X3.

[0035] Here, Figure 3 The connecting component 43 on the right front side and the connecting component 44 on the left front side shown have essentially the same structure, except for their different positions. The connecting component 43 on the right front side is positioned at the aforementioned right side X2, spanning between the rear sunroof 30 and the front rear roof reinforcement 8, and is thus fixed in place. (See reference...) Figure 3 as well as Figure 6 The connecting member 43 on the right front side gradually slopes downwards as it faces forward, forming outwardly extending left and right flange portions 431 and 432 on its right and left edges. Furthermore, the rear left and right flange portions 431 and 432 of the connecting member 43 on the right front side overlap and are fixed to the front edge (extended end) of the front frame portion 313 of the opening reinforcement 33. Additionally, the front left and right flange portions 431 and 432 overlap and are fixed to the lower surface of the front rear roof reinforcement 8. Moreover, Figure 3 The connecting component 44 on the left front side, like the connecting component 43 on the right front side, is transversely mounted and fixed between the front frame 313 of the rear sunroof section 30 and the front rear roof reinforcement 8. Figure 3 For convenience, the reference numerals for the left and right flange portions are omitted in the connecting component 44 on the left front side.

[0036] [Overall structure of the sunroof section]

[0037] exist Figure 3 In the rear sunroof section 30 shown, the connecting parts 43 and 44 are only located on the front side (the side of the vehicle sunroof structure) where the front frame section 313 of the rear sunroof section 30 is located, and are separated from the imaginary axis VL1. Therefore, the front side of the rear sunroof section 30 is moderately restricted by the connecting parts 43 and 44 to minimize vertical vibration. Furthermore, the rear side (the other side of the vehicle sunroof structure) where the rear frame section 314 of the rear sunroof section 30 is located on the opposite side of the front and is not equipped with any connecting parts. Therefore, the rear side of the rear sunroof section 30 becomes a relatively easy part to vibrate vertically by adjusting and controlling the rigidity of the connecting parts 43 and 44 as described later. In particular, by arranging the connecting parts 43 and 44 as far away as possible from the imaginary straight line VL1 (connecting parts 41 and 42 on each axle), the rear side of the rear sunroof section 30 can be made more prone to vibration. Furthermore, as described above, the rear part of the rear sunroof 30 is integrated with the roof panel 4 and fixed to the rear roof reinforcement 9 (second frame component) located behind it. Therefore, the rear part of the rear sunroof 30 can vibrate up and down while the installation of the roof glass 31 relative to the roof 3 is ensured.

[0038] Moreover, refer to Figure 3 as well as Figure 6 The rigidity of each connecting component 43, 44 can be controlled by adjusting the thickness dimension D (plate thickness) of each connecting component 43, 44. Furthermore, the rigidity of each connecting component 43, 44 can also be adjusted by changing the type of material and the structure. Therefore, in this embodiment, by adjusting the rigidity of each connecting component 43, 44, the vibration mode (amplitude, phase, etc.) of the rear part of the rear sunroof 30 is set to suppress resonance with the vehicle body, i.e., to cancel the shaking of the rear sunroof 30 that generates noise. Here, the appropriate vibration mode of the rear sunroof 30 (the rigidity of each connecting component 43, 44) is not fixed, but is selected considering the structure of the rear sunroof 30 and the overall vehicle. There is no particular limitation on the method for selecting the rigidity of the connecting components; for example, multiple connecting components with different rigidities can be prepared, and the connecting component that generates less noise can be selected. That is, multiple rear sunroofs 30 using connecting components with different rigidities are prepared, and a predetermined range of vibration frequencies is input to each rear sunroof 30. Then, within the range of vibration frequencies (Hz) in which each rear sunroof section 30 resonates, the intensity (dB) of the generated noise is measured, and noise intensity below a predetermined target value is selected.

[0039] [The operation of a sunroof structure in a vehicle (the operation of the connecting parts on the axle and the operation of the connecting parts)]

[0040] exist Figure 1 In the vehicle 2 shown, from the viewpoint of ensuring NV performance, it is desirable that the rear sunroof 30 is configured to be difficult to resonate with the vibration of the vehicle body 11. Therefore, in the vehicle sunroof structure SM, as Figure 3 As shown, the system includes: connecting parts 41 and 42 on each axle, which connect the rear sunroof 30 to the left and right roof side rails 5a and 5b (first frame members) on an imaginary axis VL1 passing through the center of gravity 300 of the rear sunroof 30; and connecting parts 43 and 44, which connect the rear sunroof 30 to the front rear roof reinforcement 8 (second frame member) at positions different from the connecting parts on each axle. With the above structure, the rigidity of each connecting part 43 and 44 can be adjusted, allowing the rear side of the rear sunroof 30 without connecting parts (the other side of the vehicle sunroof structure) to vibrate up and down with the left and right axle connecting parts 41 and 42 as fulcrums (see reference). Figure 6 (Hollow arrow).

[0041] Therefore, in this embodiment, as described above, the vibration mode of the rear portion of the rear sunroof 30 (the rigidity of each connecting component 43, 44) is set to suppress resonance with the vehicle body, i.e., to cancel the shaking of the rear sunroof 30 that generates noise. Therefore, when vibrations from the vehicle during travel are transmitted to the rear sunroof 30, the rear side of the rear sunroof 30 is forced to vibrate up and down to suppress resonance with the roof panel 4 behind it. In this way, the vibration of the rear side of the rear sunroof 30 suppresses resonance, thereby minimizing the generation of noise caused by such resonance. Furthermore, in the vehicle sunroof structure SM, since resonance is suppressed by the vibration of the rear sunroof 30 (rear portion), there is no need to install a separate mass damper, minimizing the increase in vehicle 2 weight. Thus, the vehicle sunroof structure SM becomes a vehicle body structure that effectively controls NV performance, contributing to the lightweighting of vehicle 2 and the optimization of the vehicle body structure. Therefore, according to this embodiment, the weight increase of vehicle 2 can be suppressed, and the resonance of the rear sunroof 30 can be suppressed.

[0042] Furthermore, in the vehicle sunroof structure SM, by setting multiple or single connecting parts (43, 44) at desired positions with reference to other imaginary axes VL2, the rear of the rear sunroof section 30 can be vibrated more reliably. In particular, by setting connecting parts (43, 44) on or near other imaginary axes VL2 orthogonal to the imaginary axis VL1, and as far away as possible from the connecting parts 41, 42 on each axle, the rear of the rear sunroof section 30 is made more prone to vibration. In addition, the rear side of the rear sunroof section 30 (the other side of the vehicle sunroof structure) is reinforced by the rear roof reinforcement 9 (second frame member) on the rear side, which helps to ensure the installability relative to the roof 3. Moreover, in this embodiment, by making the connecting parts 41, 42 on each axle, which serve as fulcrums, highly rigid, the installability of the rear sunroof section 30 can be ensured more reliably, and the rear side of the rear sunroof section 30 can be made more prone to vibration.

[0043] [Variation Example]

[0044] The vehicle sunroof structure of this embodiment is not limited to the above-described embodiment and can be obtained through various other embodiments. Although the structures of the connecting member and the on-axle connecting member are illustrated in this embodiment, it is not intended to limit these structures. For example, a rigidity difference may or may not be provided between the connecting member and the on-axle connecting member. Furthermore, the shapes of the on-axle connecting member and the connecting member can be various, including rod-shaped and column-shaped, in addition to plate-shaped. The number and placement of the connecting members are appropriately set considering the strength of the connecting members, and can be either single or multiple (3 or more). Moreover, the shapes and dimensions of the multiple connecting members (on-axle connecting members) can be the same or different. Additionally, utilizing… Figure 3The connecting component shown connects the rear sunroof to the rear roof reinforcement (second frame component), which also allows the front side of the rear sunroof (the other side of the vehicle sunroof structure) to vibrate easily. Furthermore, in this case, the front side of the rear sunroof is fixed to the front rear roof reinforcement (second frame component). Additionally, the other side of the vehicle sunroof structure does not necessarily have to be fixed to the first frame component or the second frame component (for example, it can be omitted). Figure 3 (The rear roof reinforcement shown).

[0045] Furthermore, the placement of the axle-connecting components can be based on an imaginary axis extending along the roof surface in the vehicle width direction, front-rear direction, or similar directions. For example, refer to... Figure 3 When an imaginary axis extending in the front-to-back direction is established, the sunroof section can be connected to the front and rear rear roof reinforcement members (second frame members) using an axle connecting member. Furthermore, in this case, the rear sunroof section can be connected to either the left or right roof side rail (first frame member) using the connecting member. In this case, either the right or left side of the sunroof section becomes the other side of the vehicle sunroof structure, fixed to either the left or right roof side rail (first frame member). Alternatively, the imaginary axis or other imaginary axes can be assumed to be diagonal relative to the multi-rectangular sunroof section. Moreover, other imaginary axes can extend in appropriate directions intersecting the imaginary axis, and do not necessarily have to be orthogonal.

[0046] Furthermore, the structures of vehicle 2, roof 3, and sunroof 30 can be appropriately modified. For example, the sunroof can be positioned at an appropriate location on the roof (e.g., the front sunroof, the rear side of the roof, etc.). In addition to being rectangular from a top view, the shape of the sunroof can also be set to various polygonal, circular, semi-circular, elliptical, or other arc-shaped forms. Furthermore, the structure and installation method of the roof glass, and the structure and installation method of the opening reinforcement, can also be appropriately set according to the vehicle's structure. Moreover, the fixing methods for the roof glass and opening reinforcement can vary depending on the material, employing methods such as bonding, fastening, or welding. Additionally, as the first and second frame components, various reinforcing structures (rigid structures) installed on the roof can be used; these do not necessarily need to be orthogonal, as long as they are arranged in a cross shape.
