Herein, "glass" is an amorphous inorganic non-metallic material, and is generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as main raw materials, and a small amount of auxiliary raw materials are added, and the main components are silicon dioxide and other oxides. As daily necessities in people's life, glass with a relatively large size is often used in the fields of buildings, vehicles and the like. Hereinafter, the description will be made with the application of the glass carrier to the transportation of window glass including, but not limited to, front windshield glass, rear windshield glass, sunroof glass, door glass. In addition, the glass transportation frame of the utility model can be applied to the environment such as doors and windows or curtain walls, aircraft glass or steamship glass, etc.

It has been recognized that larger sized glass pieces are subject to collision with each other and with the transportation rack during transportation due to jolting of the transportation vehicles, causing the glass pieces to break. At present, the transportation device for transporting glass generally adopts a trolley or a trolley with a surrounding frame, and the like, and after the glass is horizontally placed or vertically placed, the edge of the glass is protected by using a soft material so as to avoid the glass from being damaged. This is possible for short haul environments. However, when the glass needs to be transported to a great distance, for example by means of a vehicle, some unnecessary load may be applied to the glass on the way, even resulting in damage to the glass. Thus, there is a need for a manufacturer or user to reduce the rate of glass breakage during transportation due to external loads.

Fig. 1 shows a glass transport rack (hereinafter referred to as a transport rack) 10 according to an embodiment of the present invention. The transportation frame 10 includes a support frame that defines a glass placing space and includes a bottom frame 11 and a plurality of longitudinal beams 12 extending from the bottom frame 11, and a cross beam 13 is provided between at least two adjacent longitudinal beams 12, and a positioning assembly. It will be understood that the underframe is generally arranged parallel to the ground or horizontal plane, the stringers referring to structural beams extending in a substantially vertical direction from the underframe and the beams referring to structural beams extending in a substantially horizontal direction. In the illustrated embodiment, the bottom frame is generally rectangular and is enclosed by the longitudinal beams disposed at each corner of the rectangle and one or more cross beams disposed between the longitudinal beams to form a three-sided frame-shaped structure, so that a plurality of glasses can be sequentially mounted to the transportation frame. However, the illustrated configuration is merely exemplary and the support frame may be configured in other suitable configurations for holding glass. For example, in the case that the bottom frame is substantially rectangular, the frame structure may be a double-sided enclosure or even a single-sided enclosure.

The transportation rack 10 further comprises a positioning assembly, as shown in fig. 1, which comprises a limiting seat 15 and a plurality of stops 17, one stop 17 being exemplarily shown in the figure. In some embodiments, the stopper may be disposed over the entire bottom frame 11, and may be provided with a plurality of receiving grooves disposed in sequence to be suitable for vertically stopping and supporting a plurality of glasses substantially over the entire bottom of the glasses. In view of simplifying the structure, a pair of stopper seats may be provided, and a pair of stopper seats 15 is exemplarily shown in fig. 1. The pair of limiting seats are respectively disposed at two ends of the bottom frame 11 and connected to the bottom frame 11 through the supporting frame 14. In some embodiments, for a glass in a regular (e.g., rectangular) configuration, a pair of stops can support the bottom of the glass in a generally parallel manner. Advantageously, a pair of stop blocks 15 are arranged towards each other at an angle with respect to the bottom frame 11 to adapt to the edge shape of the glass, in particular the windscreen 20 illustrated in fig. 1 with the edge shape of the bottom corner area. A plurality of stops 17 (one stop 17 is shown by way of example in fig. 1) are arranged adjacent to the top of the glass, advantageously arranged in correspondence of a plurality of housing grooves attached to the mounting beam 16 between two adjacent longitudinal beams 12 and arranged in sequence along the mounting beam 16 suitable for spacing and clamping adjacent glass, at least avoiding a movement of the glass in a horizontal direction. It will be appreciated that the mounting beam 16 also acts as a form of cross beam, serving both to mount the plurality of stops 17 and to provide structural support. The cross-section of the mounting beam 16 may be of any shape. Advantageously, the non-circular cross-section helps to limit movement of the stop 17 in a generally vertical direction. Alternatively, the plurality of stoppers 17 may be moved along the mounting beam 16 to adjust the distance between the adjacent stoppers, thereby being applicable to transport of glass having various thicknesses and/or quantities, securing the fixing effect to a plurality of glass, and improving the stability during the transport of glass.

As shown in fig. 2, the limiting seat 15 includes an attachment portion 151 adapted to be connected to a support frame and a bearing portion 152 for containing and bearing glass, and a plurality of receiving grooves 153 arranged in sequence are provided on the bearing portion 152 to limit the glass in a vertical direction. In some embodiments, the support frame includes a connection portion 141 connected to the bottom frame 11 and a support portion 142 supporting an attachment portion 151 of the stopper 15, and is generally made of a metal material such as iron or stainless steel to provide sufficient support strength. Alternatively, the spacing block 15 is made of plastic, for example, and may be bolted to the support bracket 14 by side bolts.

Through static simulation and field testing, the inventors have found that for windshields, the glass can withstand a certain static load, for example a maximum principal stress of about 2Mpa in the case of the bottom corners of the glass 20 being carried by a pair of stop blocks 15 as shown in fig. 1, i.e. the glass does not break when resting statically in the transport rack 10, using the transport rack 10 in the manner shown in fig. 1.

In practice it has been found that, on the one hand, after a plurality of glasses have been positioned by means of the stop 15 and spaced apart from one another by means of the stop 17, the glasses are well retained in the receiving groove due to gravity. However, in the transportation, because the coefficient of friction between glass and plastic material's spacing seat 15 is lower, glass easily takes place to remove in the storage tank, and this just causes the position of glass bottom and storage tank contact to produce wearing and tearing, and the trace along with wearing and tearing is more and more dark, probably leads to the contact surface of glass and bottom storage tank to diminish to cause glass to receive local concentrated atress. On the other hand, as shown in fig. 3, the stopper 17 is disposed adjacent to the top of the glass 20 and includes a link 171 connected to the mounting beam 16 and a clamp block 172 provided at a free end of the link 171. In an extreme transportation environment, it is found that the stopper is moved from the original position P1 to the position P2, which also means that the contact position of the glass 20 with the bottom receiving groove is changed. The reason for this variation may be jerking due to acceleration, deceleration or road surface irregularities of the vehicle during transport, or may be due to the configuration of the glass itself. Specifically, the windshield has a convex lower contour between the pair of limiting seats, as shown in fig. 1, once the glass is separated from the bottom accommodating groove due to bumping, the lower contour may move into the accommodating groove, so that the glass is entirely inclined. Whatever the case the glass moves means that the glass is not properly constrained during transportation and is subjected to undesirable dynamic loads, which in turn increases the breakage rate of the glass. To this end, the present application is directed, inter alia, to mitigating the dynamic loading of the glass and providing a corresponding damping structure to better constrain the movement of the glass.

It should be noted that the above description provides information related to the present invention, but is not meant to be prior art.

Based on the above concept, by dynamically simulating the road condition when the vehicle passes through an uneven road surface, the inventor finds that when the glass freely falls at a position 5mm away from the bottom surface of the accommodating groove of the limiting seat, the maximum principal stress of the contact part between the corner of the bottom of the glass and the accommodating groove is increased from 2Mpa under the static condition to 12Mpa at the moment of contact. In other words, in the case where the glass is moved upward by an upward impact force generated by bumping and then falls, a portion of the glass in contact with the receiving groove is subjected to a considerable concentrated stress, which is also a cause of breakage of the glass.

So, according to the utility model discloses, be equipped with the buffer part in order to absorb glass at least at the ascending impact energy of vertical side at spacing seat.

Preferably, the buffer part is arranged between each limit seat and the corresponding support frame, namely the limit seats are not in direct contact with the support frame.

In some embodiments, the buffer portion is a flexible layer sandwiched between the spacing seat and the support frame. For example, the thickness of the bottom of the spacing block can be reduced, and a flexible strip can be inserted between the bottom of the spacing block and the supporting frame to serve as a flexible layer, so that the method is simple, economical and easy to implement.

As shown in a partial schematic view of the spacing block 250 of an embodiment illustrated in fig. 4, the spacing block 250 includes an attachment portion 251 adapted to connect with a support frame and a bearing portion 252 for receiving and bearing glass, and a plurality of receiving grooves 253 (one receiving groove 253 is illustrated in fig. 4) are sequentially arranged on the bearing portion 252 to be adapted to position the glass in a vertical direction. The flexible layer 254 is interposed between the bearing portion 252 and the attachment portion 251, so as to absorb impact energy when the glass in the accommodating groove 253 is impacted and tends to move in the vertical direction, thereby preventing the glass from moving in the vertical direction and being damaged.

Alternatively, the flexible layer is made of a softer material with the elastic modulus of less than about 50Mpa, and the flexible layer is arranged between the limiting seat and the supporting frame, so that a larger contact area between the accommodating groove and the glass can be ensured. In some embodiments, the flexible layer may be adhesively secured to the spacing block and/or the support frame, respectively.

In some embodiments, the flexible layer may be selected from foam layers or foam layers of different thicknesses, depending on the material used. In some embodiments, the flexible layer may be a single layer or a stack of multiple layers.

In some embodiments, as a modification of the mode shown in fig. 2, the buffer part may be further provided as a space layer formed between the limiting seat and the supporting frame. That is, when passing through side bolted connection with spacing seat and support frame, reserve the clearance between the two promptly. Optionally, the thickness of the voided layer is greater than 5mm. In this way, when external force acts on the limiting seat, the existence of the gap layer allows the plastic limiting seat to absorb impact energy through deformation, and the effect of preventing glass from being damaged is also achieved.

As can also be seen from fig. 4, the receiving groove of the stopper seat may be configured to be tapered from the open end toward the closed end. Therefore, when the accommodating groove is used for limiting the glass, the glass is fixedly held to a certain extent, and the glass is prevented from moving under the impact force.

Through the design as above, the utility model discloses a transportation frame has effectively absorbed the impact energy that glass especially the ascending motion of vertical side leads to in the transportation by the deformable characteristic that buffering portion provided to form good shock attenuation guard action to glass, show the breakage rate that has reduced glass.

Advantageously, the present application also proposes improvements to the stop which provide adequate restraint to the glass to at least avoid movement of the glass in the vertical direction, i.e. the stop is arranged to avoid movement in a substantially vertical direction during transport. Fig. 5 to 8 show different embodiments of the stopper, which is made of a soft material such as plastic or rubber to avoid damage to the glass.

In the stopper 270 of the first embodiment shown in fig. 5, similarly to fig. 3, the stopper 270 includes a link 271 and a clamping block 272 on which a damping portion is provided to increase a frictional force between the glass and the stopper, thereby restricting the movement of the glass. The damping portion may be made of a flexible material, for example, the damping portion may be a rubber layer (not shown) attached to the clamping surface of the clamping block 272, and the rubber layer may be adhesively connected to the clamping surface.

It will be appreciated that when the stops are applied to space adjacent glass and to perform a clamping action, the clamping blocks include an opposed pair of clamping surfaces, with the damper advantageously covering at least a majority of the clamping surfaces, except for the outermost stop. And corresponding to the outermost stop, the damping part covers at least most of the clamping surface of the clamping block facing at least towards the inner side of the transport carrier.

In the stopper 370 of the second embodiment shown in fig. 6, similarly, the stopper 370 includes a link 371 and a clamping block 372, and the damping portion is a suction cup 373 attached to a clamping surface. Typically, the suction cup is made of a rubber material. In this embodiment, the suction cup 373 is formed integrally with the clamping block 372, for example by injection molding. Alternatively, the suction cup may be adhesively connected to the clamping block. Advantageously, the suction cup 373 has a cross-sectional dimension substantially the same as or slightly larger than the cross-sectional dimension of the clamping surface, so as to provide a sufficiently large active surface. However, designs in which the cross-sectional dimension of the suction cup is smaller than the cross-sectional dimension of the clamping surface are not excluded, e.g. the active surface of the suction cup substantially covers the central area of the clamping surface. In this way, the suction cup design provides elastic restraint, as compared to the way the rubber layer is provided, so that the stopper can connect adjacent glasses together by suction, better ensuring that the glasses are held in place, and also holding the stopper in place.

In some embodiments, the suction cup is attached to the clamping surface by a flexible connection. Fig. 7 shows a third embodiment of a stop block 470, and similarly, the stop block 470 comprises a connecting rod 471 and a clamping block 472, and a clamping surface of the clamping block 472 is provided with a suction cup 473 connected by a flexible connector 474. In this embodiment, a plurality of small-sized suction cups 473 are uniformly distributed on the clamping surface, and accordingly, the cross-sectional size of each flexible connecting member 474 is equal to or smaller than that of the suction cups 473. In this way, a plurality of small suction cups are apt to absorb or follow the curved surface of the glass, providing a more reliable constraint, the flexible connection between the suction cups and the stop blocks then allowing the suction cups to have a longer size, having a certain degree of freedom, to fall off the glass surface more easily when it is necessary to release the constraint.

The stop 570 of the fourth embodiment shown in fig. 8 is similar to the stop 470 shown in fig. 7 and described above, comprising a connecting rod 571 and a clamping block 572, the clamping surface of the clamping block 572 being provided with suction cups 573 connected by a flexible connection 574, with the difference that the suction cups 573 are large suction cups having a cross-sectional dimension substantially the same as the cross-sectional dimension of the clamping block 572.

Alternatively, the suction cup and the flexible connector are formed in one piece, for example by injection moulding. Alternatively, the flexible connector is formed integrally with the clamping block, or the flexible connector is connected to the clamping block by means of an adhesive.

As can be seen from the above description, the glass transportation frame of the utility model utilizes the spacing seat and the stop dog to effectively limit the large-size glass of especially windshield glass, and through setting up the buffer part on the spacing seat, in case glass breaks away from the spacing seat under the effect of jolting impact force in the transportation and then can absorb impact energy, avoids glass to shift and damage. In addition, the damping part is arranged on the stop block, so that proper restraint can be provided for the glass, and the stability and the safety in the transportation process are further improved. The utility model discloses effectively reduce or even eliminated the breakage rate in the jumbo size glass transportation, have beneficial effect such as simple structure, performance promotion are obvious and cost economy.
