EXTENDABLE MAGAZINE, FILLED MAGAZINE AND USE

Description

[0001] The invention is based on a magazine which is suitable for receiving at least one fastening means.

[0002] Often, building elements, such as installation components, must be attached to walls, ceilings, or floors of a building, etc., using fasteners. Since a large number of such fasteners are required for this purpose, magazines are used. These make several fasteners easily available to one user.

[0003] From DE10162635 A1, for example, a band-shaped screw magazine is known that can be used for fastening devices such as screws.

[0004] Another magazine is known from WO 2010 / 000381 A1.

[0005] Some fasteners have a collar. Together with the fastener head, such a fastener is comparatively heavy. The weight is particularly unevenly distributed across the length of the fastener. Depending on the magazine position, there may be a risk of the fastener falling out of the magazine.

[0006] The object of the present invention is therefore to offer a magazine that enables secure storage of fastening devices with collars.

[0007] The object is achieved by a magazine according to claim 1, suitable for receiving at least one fastening means, wherein the magazine comprises at least one receiving cell, each receiving cell having a cell frame with a through-opening, the through-opening extending through the receiving cell, each receiving cell having a plurality of engagement fingers extending from the cell frame with their free end into the through-opening, each of the engagement fingers having at least one web. A fastening means with a collar can be inserted into the through-opening along an insertion direction. The insertion direction can be perpendicular or substantially perpendicular to a plane spanned by the respective cell frame. "Substantially" can correspond to a deviation of, for example, at most 10 degrees, in particular at most 5 degrees, from the vertical.

[0008] This allows multiple fasteners to be inserted into the same receiving cell one after the other and then removed again. The magazine can therefore be used multiple times.

[0009] One or more of the engagement fingers, particularly with their webs, can grip the fastener at its collar and / or hold it in the magazine.

[0010] An engagement finger can be understood, for example, as an elongated section of the cell frame that protrudes from it. The engagement finger can also be a part formed separately from the cell frame. The engagement finger can have a free end.

[0011] The web can extend laterally from the respective engagement finger. "Laterally" can be understood as a direction in a vertical plane or in a plane at least substantially perpendicular to the insertion direction.

[0012] At least one engagement finger of a receiving cell can have at least two webs. The webs can be formed at different heights along the insertion direction. The engagement finger can then at least partially enclose the collar simultaneously at several locations, for example, on both a top and a bottom.

[0013] The engagement finger can be elastically deformable. This allows different types of fasteners, for example, with different collar sizes, to be held in the same magazine.

[0014] In particular, the engagement finger can have a higher spring stiffness along the insertion direction than perpendicular to the insertion direction. It can have an asymmetrical cross-section, at least in one area.

[0015] When the fastening element is inserted into the through-opening, it can contact the engagement finger, for example with its collar. Upon such contact, the fastening element can press against the engagement finger. The engagement finger can be configured to pivot outwardly due to the pressure, in particular out of the through-opening and / or toward the cell frame. Due to the different, direction-dependent spring rates of the engagement finger, the engagement finger can pivot at least substantially laterally and preferably not at all, or only to a small extent, along the insertion direction.

[0016] The pivoting can be precisely controlled if at least one engagement finger of a receiving cell has a control contour. The control contour can be configured so that, when pressure is applied to the control contour along the insertion direction, the engagement finger pivots out of the through-opening. "Pivoting out" can mean that the engagement finger leaves the through-opening. Alternatively or additionally, this can also mean that the engagement finger remains in the area of ​​the through-opening but moves away from a center of the through-opening due to pressure, for example, toward the cell frame.

[0017] Thus, the through-opening can be opened by inserting the fastening means. The fastening means, in particular with its collar, can pass between the engagement fingers. The engagement fingers can then hold the fastening means, in particular through their webs. The engagement fingers can be configured in particular so that the collar is locked into them, in particular between the webs.

[0018] Two adjacent magazine cells can be connected to each other via a connecting section. The connecting section can have a low spring rate.

[0019] In particular, the connecting section can have a lower spring rate than a receiving cell, especially an adjacent one. Thus, the magazine can be particularly flexible in the area of ​​the connecting section. Overall, a flexibly deformable magazine can be formed. The magazine can, for example, be wound.

[0020] To link multiple magazines together, the magazine can have at least one connector. The connector can be configured to connect to another magazine.

[0021] In particular, the connector can be designed as a symmetrical connector. This means that it can be connected, for example, plugged together, with a second, similar connector.

[0022] Alternatively, the connector can also be designed as an asymmetrical connector. In particular, there can be a male and a female connector. For example, the female connector can have a socket section. The male connector can have a plug section. The plug section can be designed congruently with the socket section.

[0023] The magazine can comprise at least one female connector and at least one male connector congruent with the female connector. Thus, several magazines can be connected by successively connecting, in particular plugging, a male connector to a female connector.

[0024] To prevent accidental slipping out, at least one of the connectors can have a locking mechanism or at least a partial locking mechanism. One or more of the engagement fingers can also jointly form a locking mechanism. A partial locking mechanism can be understood as meaning that the connector has a structure configured to engage with another, not necessarily identical, connector from a different magazine.

[0025] Experience has shown that residual materials on construction sites are not always disposed of properly. Therefore, it is desirable for any residual materials to be environmentally safe. Therefore, the invention provides for the magazine to be made of a biodegradable material.

[0026] For example, a material can be considered biodegradable if it undergoes 90 percent biodegradation in an aqueous medium within 180 days. Alternatively or additionally, a material could also be considered biodegradable if it meets a standard applicable to that material regarding compostability and / or biodegradability.

[0027] Such a material can, for example, comprise a natural fiber. It is also conceivable that the material comprises wood. Alternatively or additionally, it can also comprise grass. For example, the biodegradable material can comprise paper, cardboard, hemp, and / or bamboo. It can also comprise a biodegradable plastic.

[0028] This helps prevent environmental damage, even if a user of the magazine does not dispose of it properly after use.

[0029] In this case, it is particularly advantageous if the magazine is completely biodegradable. "Completely" can be limited to a main component of the magazine. For example, "completely biodegradable" can also include a magazine that contains very small amounts, for example, less than 5 percent by weight, in particular less than 1 percent by weight, and particularly preferably less than 1 per thousand by weight, of non-biodegradable substances. Such substances can be, for example, color pigments from labels or the like on the magazine. However, it is also particularly preferred if labels or the like are also made of biodegradable materials.

[0030] The magazine can be particularly easy to handle if it is designed in a strip shape.

[0031] For example, to be able to remove a specific number of fasteners from the magazine in one go, the magazine can have a perforation and / or a constriction in at least one location. The magazine can be divided into several parts along the perforation or constriction.

[0032] In order to be able to use the magazine easily with a machine tool, for example a hand-held power tool or a construction robot, the magazine can have a hole pattern and / or a guide groove.

[0033] The scope of the invention also includes a filled magazine. The filled magazine comprises a magazine of the type described above. The magazine is filled with at least one fastening means having a collar. In at least one of the fastening means, the collar of the fastening means can be held by at least one engagement finger.

[0034] Preferably, the filled magazine has a plurality, for example at least 5, 10 or 20, fastening means.

[0035] The fastening device can be, for example, a screw anchor. Alternatively or additionally, it can also be a nail. For example, it can be a concrete anchor, such as a concrete screw.

[0036] It is also conceivable that the fastening device is designed to secure insulation materials. In particular, it can be designed as an insulation anchor with a collar.

[0037] The scope of the invention also includes a use A filled magazine of the type described above is used by a construction robot to insert a fastener into a ceiling and / or a wall at a construction site. The construction site can be and / or include, for example, a building construction and / or civil engineering site.

[0038] The construction robot can have a machine tool, for example, a setting device for setting the fastener. It can have a manipulator. The machine tool can be arranged on the manipulator. The manipulator can be designed, for example, as a multi-axis arm. It can also have a lifting device. The manipulator can have at least three degrees of freedom, for example, at least six degrees of freedom. In particular, the construction robot can then be configured to carry out construction work, in particular to set the fasteners, in the ceiling and / or the wall.

[0039] The magazine can be arranged on the machine tool. The machine tool can be configured, particularly in cooperation with the manipulator, to remove fastening elements from the magazine one after the other and insert them, particularly into the ceiling and / or wall.

[0040] Because the fasteners can be securely held in the magazine regardless of its position and thus cannot accidentally fall out, the machine tool can set the fasteners in almost any position and / or direction, especially horizontally and / or vertically. The machine tool can be repositioned at high speed without fasteners falling out of the magazine due to acceleration. This allows for a high setting frequency on a construction site. Furthermore, the reliability of the setting processes can be increased through the use of the magazine. This is particularly important when using construction robots, and in particular to achieve the highest possible degree of autonomy.

[0041] Further features and advantages of the invention will become apparent from the following detailed description of exemplary embodiments of the invention, based on the figures of the drawing, which illustrate details essential to the invention, and from the claims. The features shown therein are not necessarily to scale and are presented in such a way that the special features of the invention can be clearly seen. Within the scope of protection defined by the claims, the various features can be implemented individually or in groups in any combination in variants of the invention.

[0042] The schematic drawing shows embodiments of the invention and explains them in more detail in the following description. They show:

[0043] Fig. 1 shows a perspective view of a filled magazine; Figs. 2 and 3 show perspective views of connectors; Fig. 4 shows a top view of a receiving cell with a fastening means; Figs. 5 and 6 show cross-sectional views of the receiving cell with the fastening means according to Fig. 4 ; and Fig. 7 and 8 enlarged detail views of the cross-sectional views from Figs. 5 and 6 .

[0044] In the following description of the figures, the same reference numerals are used for identical or functionally equivalent elements to facilitate understanding of the invention. To simplify the illustration, in each figure, where several identical elements are shown, only one of the elements is generally provided with a reference numeral.

[0045] Fig. 1 shows a filled magazine 10 in a perspective view.

[0046] The filled magazine 10 has a magazine11 The magazine 11 is designed as a strip. It is therefore strip-shaped.

[0047] In the magazine 11 there are several fastening devices 100 The magazine 11 has several storage cells 12 on.

[0048] Each of the receiving cells 12 has several, in particular three, engagement fingers 14 The engagement fingers 14 are each located on a cell frame 16 of the respective receiving cell 12. In their interior, the cell frames 16 each have through openings 18According to the invention, the magazine 11 is made of a biodegradable, preferably completely degradable, material, for example, a biodegradable plastic. Thus, the engagement fingers 14 can continue to be elastically deformable. In addition, environmental damage caused by improper disposal of the magazine 11 can be avoided. The release of microplastics into the environment can also be counteracted.

[0049] The fastening means 100 each have a head 110, a collar 112 and a shaft 114 on.

[0050] In this embodiment, the fastening means 100 with the collar 112 is designed as a screw anchor. For this purpose, it has a thread 115 The fastening means 100 can be, for example, a concrete screw.

[0051] Adjacent to the receiving cells 12 there are connecting sections 20.The connecting sections 20 are flexible and elastic. They each have comparatively low spring rates. For this purpose, they can be thinner and / or narrower and / or made of a different material than the other sections of the magazine 11.

[0052] At its two long ends, the magazine 11 has connectors 22 and 24 The connectors 22, 24 are designed to connect several similar magazines 11 to one another.

[0053] Fig. 2 and 3 show such connectors 22, 24 in a perspective view and in a front view.

[0054] Two magazines 11, which may, for example, be constructed in the same way, in particular identically, are connected to one another via the connectors 22, 24.

[0055] For this purpose, the connector 22 is designed as a male connector. It has a plug-in section 26The connector 24 is complementary to the connector 22 and is designed in particular as a female connector. For this purpose, it has a socket section 28 As can be seen particularly from Fig. 3 As can be seen, the male connector 22 has several locking tabs 30 The locking tongues 30 of the plug-in section 26 can be associated locking sections 32 of the socket section 28. The connectors 22, 24 thus each form a partial locking mechanism. Together, they form a locking mechanism. By means of the locking mechanism, the connectors 22, 24 are held together in the mated state, even under tensile loads or the like.

[0056] Fig. 4 shows a top view of a receiving cell 12 with its cell frame 16 and a fastening element 100.

[0057] Three engagement fingers 14 engage the cell frame 16. With their free ends, they narrow a central, free area of ​​the through-opening 18. In particular, they encompass 34 the collar 112 of the fastening means 100.

[0058] Fig. 5 shows a cross section of the receiving cell 12 according to the section line V from Fig. 4 and Fig. 6 shows one according to the section line VI out of Fig. 4 .

[0059] It can be seen in each case that the fastening means 100 sits with its collar 112 in the through-opening 18. For this purpose, it is held in the through-opening 18 by the engagement fingers 14.

[0060] Each engagement finger 14 can have a control contour 36 The control contour 36 can be designed such that when pressure is applied to it along an insertion direction R,such as can be exerted, for example, by the fastening means 100 upon insertion into the through-opening 18, the engagement finger 14 is forced out of the through-opening 18. The insertion direction R corresponds to a direction along which the fastening means 100 can be inserted into the through-opening 18.

[0061] In particular, the control contour 36 has a slope 38 whose surface is inclined to the insertion direction R.

[0062] Fig. 7 and Fig. 8 show enlarged views of the sections VII and VIII according to Fig. 5 or Fig. 6 .

[0063] In this embodiment, each engagement finger 14 has several of the webs 34.

[0064] The webs 34 protrude in particular perpendicular to the insertion direction R from the respective engagement finger 14.

[0065] As can be seen from the comparison of Fig. 7 with Fig. 8The webs 34 are arranged or formed at different heights along the insertion direction R. Their spacing along the insertion direction R can correspond, at least approximately, to a thickness of the collar 112.

[0066] The webs 34 each extend over an edge area of ​​the collar 112. The Fig. 7 The web 34 shown holds the collar 112 at an upper side, while the one shown in Fig. 8 shown web 34 holds the collar 112 on a bottom side opposite the top side.

[0067] The collar 112 is thus locked between the webs 34.

[0068] To facilitate pivoting out of the through-opening 18, the engagement finger 14 has a rectangular cross-section, at least in some areas, particularly outside the webs 34. In particular, it has a greater spring stiffness in the direction of the insertion direction R than transversely thereto. List of reference symbols
