Description

[0001] The applicant has been involved for decades in the development and manufacture of, among other things, work and cleaning equipment, in particular brooms. Brooms typically consist of a broom handle, which is made of wood, for example, and a broom head. The broom head has a base to which bristles are attached. A handle holder may be attached to the broom head to accommodate the handle and secure it relative to the broom head.

[0002] Several methods for fixing the broom handle to the broom head are known in the prior art.

[0003] For the purpose of selling a broom in retail stores, the broom handle and head are usually provided unassembled, but combined into a single handling unit. This unassembled state, also known as the transport state or transport-assembly state, facilitates transport and product presentation at the point of sale due to the reduced volume.

[0004] It is particularly common to attach the broom head to the broom handle, for example, using a cable tie or a fastening tab. The cable tie can be removed after the sale. The broom head is then usually attached to the handle by the buyer after the sale.

[0005] Furthermore, it is known from DE 20 2025 100 843 U1 of the applicant to provide a device with which a broom head and a broom handle can be securely positioned relative to each other for transport and for providing a handling unit for retail sale. Due to an arrangement of openings, the device can also serve to secure the broom to a wall after the sale.

[0006] For this purpose, the known device has openings that can be penetrated by fastening screws.

[0007] A receiving section of the known device can, in the wall-mounted state of the device, serve to receive the broom handle of the mounted broom, and thus detachably clamp the entire broom, i.e. broom head and broom handle, to the mounting surface.

[0008] The prior art device comprises a receiving section in the form of a spring clip. This clip has several curved sections with differently shaped curvatures. The spring clip enables a radial expansion of the receiving section.

[0009] Starting from this, the object of the invention is to further develop the known device in such a way that it ensures an improved clamping hold of the broom handle while maintaining a simple construction.

[0010] The invention solves this problem with the features of claim 1.

[0011] The principle of the invention essentially consists in designing the device for holding the broom handle such that the receptacle for the broom handle is provided by two pairs of clamping legs. Each pair of clamping legs comprises a first and a second clamping leg.

[0012] In the prior art, the device comprised a clamping section with two elongated and planar or planar contact areas. Pairs of clamping legs were not known in the prior art.

[0013] The invention encompasses a device with two pairs of clamping arms. This provides the advantage of precisely defined force application points for gripping the broom handle securely.

[0014] According to the invention, the envelope contour of the receiver is formed by two pairs of clamping legs.

[0015] The invention also encompasses situations where the device has exactly two or more than two pairs of clamping legs. In this case, the clamping forces can be distributed over multiple contact surfaces.

[0016] According to the invention, it is further provided that each pair of clamping legs is firmly connected to one another via their base. The head regions of the two legs can be moved apart or away from each other by generating a restoring force and widening the receptacle.

[0017] A special feature of the invention is that each clamping leg has a stiffening profile. Because each clamping leg has a stiffening profile, e.g., an L-shaped profile in cross-section or a profile that, when considering the cross-section, has L-shaped areas, the restoring forces can be very high. This results in improved clamping of a broom handle in the holder.

[0018] A stiffening profile within the meaning of the invention is any suitable element that contributes to increasing the bending stiffness of a clamping leg.

[0019] A stiffening profile according to the invention particularly comprises a suitable geometric design of a clamping leg which causes the clamping leg, when performing an expanding movement, to generate a reliable, stable, permanent restoring force on its head areas in order to securely clamp the broom handle between them.

[0020] A stiffening profile can, for example, have a longitudinal extension in a direction that runs along an edge contour of the fixture. The longitudinal direction of the stiffening profile can also, for example, essentially run along a boundary contour of the fixture.

[0021] The invention particularly encompasses situations where the stiffening profile is essentially L-shaped in cross-section or includes material areas that are essentially L-shaped.

[0022] According to an advantageous embodiment of the invention, each clamping leg has a stiffening section that is oriented essentially transversely to the receptacle and extends, in particular, towards a central region of the receptacle. This embodiment of the invention enables a particularly stable design of the device.

[0023] According to an advantageous embodiment of the invention, the stiffening profile has an approximately L-shaped cross-section, or comprises a section with an approximately L-shaped cross-section. This embodiment of the invention enables simple construction and a stable design of the device.

[0024] According to an advantageous embodiment of the invention, a stiffening strut is provided for connecting two clamping legs of a pair of clamping legs to each other via their base areas. This embodiment of the invention enables the generation of high restoring forces and a permanently stable construction.

[0025] According to an advantageous embodiment of the invention, the stiffening strut has an approximately L-shaped cross-section, or comprises a section with an approximately L-shaped cross-section. This embodiment of the invention enables a simple design and a stable construction.

[0026] According to an advantageous embodiment of the invention, the receptacle is defined by an edge collar extending continuously along both legs of a leg pair and along the associated stiffening strut. This embodiment of the invention enables the generation of permanently high restoring forces and a stable construction of the device.

[0027] According to an advantageous embodiment of the invention, the receptacle provides an insertion ramp for the broom handle. This embodiment of the invention enables easy handling.

[0028] According to an advantageous embodiment of the invention, the device has openings for screws to secure the device to a mounting surface. This embodiment of the invention enables stable wall-side mounting of the device.

[0029] According to an advantageous embodiment of the invention, an opening is provided in each stiffening strut. This embodiment of the invention enables a particularly stable construction.

[0030] According to an advantageous embodiment of the invention, the device has a substantially ring-shaped or ring-shaped fastening section for securing a broom head. This embodiment of the invention enables the provision of a transport holder for a broom head and a broom handle.

[0031] According to an advantageous embodiment of the invention, the device is designed to provide a transport holder for a broom head and a broom handle, and alternatively, to provide a wall mount for an assembled broom. This embodiment of the invention allows for multiple uses of the device according to the invention.

[0032] According to an advantageous embodiment of the invention, the device provides several chambers of different sizes for accommodating broom handles with different diameters. This embodiment of the invention enables, for example, the storage of broom handles with different diameters and the compensation of tolerances in the broom handle.

[0033] According to an advantageous embodiment of the invention, the chambers have several curved sections with differently shaped curvatures. This embodiment of the invention enables a simple construction of the device according to the invention.

[0034] According to an advantageous embodiment of the invention, the device is formed from a plastic injection-molded part. This embodiment of the invention enables the simple manufacture of a device according to the invention.

[0035] Further advantages of the device according to the invention will become apparent from the uncited dependent claims and from the following description of the exemplary embodiments shown in the drawings.

[0037] The embodiments of the invention are explained with reference to the following description of the drawings: Exemplary embodiments of the invention are described in the following description of the figures, also with reference to the drawings. For the sake of clarity, identical or comparable parts, elements, or areas are designated with the same reference numerals, sometimes with the addition of lowercase letters, even where different embodiments are concerned.

[0038] Features described only in relation to one embodiment can also be provided in any other embodiment of the invention. Such modified embodiments are included in the invention, even if they are not shown in the drawings.

[0039] All disclosed features are essential to the invention. The disclosure of this application hereby incorporates in full the disclosure content of the associated priority documents (copy of the prior application) as well as the cited publications and the described devices of the prior art, also for the purpose of including one or more features of these documents in one or more claims of the present application.

[0040] An embodiment of a device according to the invention is designated in its entirety by reference numeral 10 in the figures.

[0041] Fig. Figure 1 shows the device 10 in its entirety in a perspective schematic view.

[0042] According to Fig. Figure 2 shows that the device 10 has a circumferential frame 39. A centrally arranged strut 14, also referred to as the central strut 14, is provided within the frame 39. The central strut 14 divides the frame 39 such that a first opening 36 and a second opening 40 are formed.

[0043] Starting from the central strut 14, according to Fig. 2 - to the left -, a ring-shaped mounting area 15 adjoins the central strut 14. This is essentially for achieving a function of the device 10, in the sense of a transport bracket 32, according to Fig. 6 is crucial.

[0044] If the device 10 functions as a transport holder 32, it serves the purpose of transporting a broom handle 11 and a broom head 12. It also serves for product presentation, e.g., in a retail store. The transport holder 32 serves to bundle and store a broom handle 11 and a broom head 12.

[0045] The one based on the Fig. 2 The ring-shaped fastening area 15 with central strut 14 and opening 36 forms a mounting eyelet.

[0046] A cord extending from a handle holder 41 of the broom head 12 can be inserted into this mounting eyelet. Fig. 6. An axial sleeve 42 (not shown) is inserted. The axial sleeve 42 has an outer diameter that is smaller than the inner diameter 44 or a clear width 44 of the mounting area 15. A screw sleeve 43 can be screwed onto the axial sleeve 42.

[0047] The screw sleeve 43 has an outer diameter that exceeds the inner diameter 44 or a clear width 44 of the fastening area 15. After screwing the screw sleeve 43 onto the axial section 42 of the stem holder 41, according to Fig. 6 a securing of the broom head 12 to the device 10 is achieved.

[0048] The Fig. 1 and Fig. Figure 2 further clarifies that the device 10 also has a receptacle 21. A broom handle 11 can be clamped in the receptacle 21.

[0049] The inlet 21 is bounded by a first pair of clamping arms 16 with clamping arms 18a, 18b and by a second pair of clamping arms 17 with clamping arms 18c, 18d.

[0050] The clamping legs 18a, 18b, 18c, 18d each have a head area 23a, 23b, 23c, 23d and a foot area 22a, 22b, 22c, 22d.

[0051] In the foot area 22a, 22b, 22c, 22d, two clamping legs of a clamping leg pair 16, 17 are connected to each other via a stiffening strut 19a, 19b. The stiffening strut 19a, 19b each has an opening 20a, 20b for the passage of screws.

[0052] Along the widening direction 24 (see Fig. 4) The head regions 23a, 23b, 23c, 23d of a pair of clamping legs 16, 17 of clamping legs 18a, 18b, 18c, 18d are slightly apart, i.e. away from each other, in order to accommodate a broom handle 11.

[0053] The clamping legs 18a, 18b, 18c, 18d can secure the broom handle 11 to the device 10.

[0054] In the event that the device 10 is used as a transport bracket 32 ​​according to Fig. 6 is formed, the broom handle 11 is securely held in the receptacle 21 by the clamping arms 18a, 18b, 18c, 18d.

[0055] The device 10 can also function as a wall mount 31 according to Fig. 7. For this purpose, the device 10 is screwed to a wall-side mounting surface 35 using screws that pass through the openings 20a, 20b, 20c.

[0056] Fig. Figure 7 shows an assembled broom 13 in the assembled state, which is held on the device 10 that is attached to the wall.

[0057] As can be seen from Fig. As can be seen in Figure 4, the device 10 has a receptacle 21 which provides several chambers 33a, 33b, 33c, 33d. The chambers 33a, 33b, 33c, 33d are of different sizes. They serve, for example, to hold broom handles 11 with different outer diameters.

[0058] The individual chambers 33a, 33b, 33c, 33d have different curvatures 34a, 34b, 34c, 34d. These different curvatures 34a, 34b, 34c, 34d allow for the enclosing of different outer contours of broom handles 11.

[0059] This device 10 enables the fixing of broom handles 11 of different sizes.

[0060] A special feature of the invention is the design of the receptacle 21 and the construction of the clamping legs 18a, 18b, 18c, 18d.

[0061] Fig. Figure 1 shows that the clamping legs 18a, 18c are connected to each other via a back wall 37.

[0062] The rear wall 37 has an approximately V-shaped indentation 45.

[0063] With the exception of this indentation 45, the rear wall 37 is continuous.

[0064] From the rear wall 37, a clamping leg 18a extends to provide a stiffening profile 25a according to Fig. 4 a stiffening section 26a away, in particular about perpendicularly or perpendicularly away.

[0065] The stiffening section 26a extends in a direction 27a transverse to the opening 21. The stiffening section 26a also extends towards a central area 28 of the opening 21.

[0066] The stiffening section 26a increases the bending stiffness of the clamping leg 18a.

[0067] The clamping leg 18c also exhibits according to Fig. 4a, as part of a stiffening profile 25c, includes a stiffening section 26c that extends along a direction 27a transverse to the mount 21. The stiffening section 26c also extends towards a central region 28 of the mount 21.

[0068] It should be noted at this point that the device 10 is designed to be symmetrical overall or substantially symmetrical with respect to its central plane 46.

[0069] The clamping leg 18b also includes a stiffening profile 25b. This is provided by a connecting wall 38b and a stiffening section 26b. Again, the stiffening section 26b extends along a direction 27b towards the receptacle 21. At the same time, the stiffening section 26b extends towards a central region 28 of the receptacle 21.

[0070] Due to the previously explained symmetry of the device 10 with respect to its central plane 46, the clamping leg 18d is designed in an analogous manner to the clamping leg 18b.

[0071] As can be seen, for example, from the Fig. 1 and the Fig. As can be seen in the overall view of Figure 4a, the device 10 also has a rim collar 29 on each of the two lateral boundaries of the receptacle 21. This extends along the contour of the clamping legs 18a, 18b, 18c, 18d and along the contour of the stiffening struts 19a, 19b.

[0072] The edge collar 29 projects outwards from the center of the recess 21. Therefore, starting from the recess 21, it projects slightly outwards in the longitudinal direction of the broom handle 11, e.g. by 1 mm to 5 mm.

[0073] The edge collar 29 also forms part of the stiffening profile 25a, 25b, 25c, 25d.

[0074] As can be seen from the sectional view of the Fig. 4a shows that the cross-section of the clamping leg 18a, in conjunction with the edge collar 29 and the stiffening section 26a, has an L-shaped section.

[0075] Furthermore, the cross-section of the clamping leg 18a, in conjunction with the stiffening section 26a and the back wall 37, has an area with an L-shaped cross-section.

[0076] A cross-section of the clamping leg 18a reveals an overall approximately double-L-shaped cross-sectional area. Therefore, a clamping leg 18a has an overall approximately Z-shaped or S-shaped cross-section.

[0077] The remaining clamping legs 18b, 18c, 18d have analogous cross-sections.

[0078] Due to the increased bending stiffness of the clamping legs 18a, 18b, 18c, 18d, a high restoring force is generated when the receptacle 21 is widened, i.e. when the head regions 23a, 23b of a pair 16 of clamping legs 18a, 18b move apart.

[0079] The high flexural stiffness, due to both material and design factors, can ensure a permanently acting restoring force. This restoring force results in a high clamping force for holding the broom handle 11 in the device 10.

[0080] To facilitate the insertion of a broom handle 11 into the receptacle 21, insertion ramps 30a, 30b, 30c, 30d are arranged on the head regions 23a, 23b, 23c of the clamping arms 18a, 18b, 18c, 18d. When a broom handle 11 is inserted into the receptacle 21, the insertion movement of the broom handle 11 automatically causes the head regions 23a, 23b, 23c to open apart.
