Description

Technical Field

[0001] This application relates to the field of one-piece molded nail-free sports flooring technology, specifically to a universal indoor and outdoor detachable nail-free sports flooring. Background Technology

[0002] Invention patent 202510348841X discloses a one-piece molded, detachable, nail-free sports floor. It allows for rapid assembly and disassembly of elastic floor modules via connecting forks and fasteners, enabling repeated assembly and disassembly of the one-piece molded, nail-free sports floor. The connecting forks include a left connecting fork, a right connecting fork, and a pointed pin, with the left and right connecting forks connected by the pointed pin. The fasteners include a front fastener, a rear fastener, and a tension bolt, with the front and rear fasteners connected by the tension bolt. Through holes are provided on the support protrusions at relative positions, and bolts are used to install and fix the connecting forks and fasteners at these through holes.

[0003] In summary, existing one-piece molded detachable sports flooring suffers from problems such as too many connecting components, cumbersome setup, and high material and installation costs. Summary of the Invention

[0004] This application provides a universal indoor and outdoor nail-free sports floor that can be removable and quickly disassembled in the front-back, left-right, and up-down directions, without relying on any connecting parts independent of the integrated floor module, such as bolts, screws, connecting forks, fasteners, etc., solely through the integrated structural design of the integrated floor module itself. This allows for the rapid and repeated disassembly and assembly of the universal indoor and outdoor nail-free sports floor technology at a lower cost.

[0005] This application provides the following technical solution: an indoor and outdoor universal detachable nail-free sports floor, comprising multiple nail-free elastic floor modules that can be spliced ​​together. Each nail-free elastic floor module includes an integrally molded floor module 1 and an elastic pad 2. The upper end of the integrally molded floor module 1 is provided with a panel 10, and the lower end, on the back of the panel 10, is provided with four supports parallel to the front and rear edges. The bottom surface of the four supports is provided with multiple recesses, and each of the multiple recesses is fitted with and bonded to an elastic pad 2. The four supports are spaced at the same distance and are connected by reinforcing supports.

[0006] The one-piece molded floor module 1 also includes multiple clips 11, slots 111, and sliders 12 symmetrically arranged on the left and right sides of the panel 10. The clips 11 protrude from the left and right side edges of the panel 10. The upper surface of the clips 11 is parallel to the upper surface of the panel 10 and flush with the lower edge of the panel 10. The bottom surface of the clips 11 is a slope with a lower inner surface and a higher outer surface. The clips 11 are provided with slots 111 recessed into the upper surface of the clips 11. The inner end surface of the slots 111 is flush with the left and right side surfaces of the panel 10. The bottom surface is arc-shaped. The inner end surface and the bottom surface transition with a slope with a higher inner surface and a lower outer surface. The sliders 12 are matched with the slots 111. The outer end surface of the sliders 12 is flush with the edge surface of the panel 10. The bottom surface is arc-shaped. The outer end surface and the arc-shaped bottom surface transition with a slope with a higher outer surface and a lower inner surface.

[0007] Preferably, each of the left and right sides of the panel 10 is provided with six locking heads 11, six locking slots 111, and six sliding heads 12, arranged sequentially from front to back along the left and right sides of the panel 10; wherein, the distance between the third locking head and the fourth locking head is twice the width of a single locking head 11 in the front-back direction; and a third and a fourth sliding head 12 are provided between the third and the fourth locking heads 11.

[0008] After two nail-free resilient floor modules are joined together at their front and rear ends and aligned at their left and right edges, the two locking heads 11 at the front and rear ends are arranged side by side on the left and right sides. The third nail-free resilient floor module is assembled at the left or right edge. After the third and fourth locking heads 11 clamp the two side by side locking heads 11, their locking grooves 111 cooperate with the sliding head 12 of the nail-free resilient floor module at its front and rear ends. The sliding head 12 cooperates with the locking groove 111 of the nail-free resilient floor module at its front and rear ends.

[0009] The dual-purpose long buckle strip 3 is a ┌-shaped right-angle buckle strip made of rust-proof metal or hard plastic with a thickness of ≥2.5mm. It is used to fix the nail-free resilient floor modules to the upper surface of the nail-free resilient floor modules on the four sides of the floor area after the nail-free resilient floor modules are installed. It is used for edge sealing and connection and fixation between adjacent nail-free resilient floor modules.

[0010] Obtaining a nail-free resilient floor module: A one-piece molded product is obtained by solidifying organic or inorganic materials that can be molded in one piece through a special one-piece molding mold; after solidification, the one-piece molded product is removed from the mold, thus obtaining a single one-piece molded floor module 1 without the elastic pad 2;

[0011] The elastic pad 2 is bonded to the recess of the support base using adhesive to obtain a single nail-free elastic floor module.

[0012] The nail-free resilient floor modules are placed on the painting production line and painted or have an anti-slip and wear-resistant layer applied according to customer requirements.

[0013] Repeat the above steps to obtain multiple nail-free resilient floor modules.

[0014] This application shall be installed in the following manner:

[0015] S1. Lay the first row of nail-free resilient flooring modules; take the first nail-free resilient flooring module and place it at the starting position on any side of the center of the site; take the second nail-free resilient flooring module and place it behind the first nail-free resilient flooring module, so that the clips 11 on the left and right sides of the front of the second flooring module are aligned with the clips 11 on the left and right sides of the rear of the first nail-free resilient flooring module; take the third nail-free resilient flooring module and place it behind the second nail-free resilient flooring module, so that the clips 11 on the left and right sides of the front of the third nail-free resilient flooring module are aligned with the clips 11 on the left and right sides of the rear of the second nail-free resilient flooring module; lay the fourth and fifth modules in the same way as the third module, until the first row of nail-free resilient flooring modules is completed;

[0016] S2. Install the second nail-free resilient floor module on the left side of the first nail-free resilient floor module; take a nail-free resilient floor module and tilt it so that it is higher on the left and lower on the right. The third and fourth clips 11 on the right side clamp the clips 11 at the front and rear ends of the two adjacent nail-free resilient floor modules of the first channel, and align the right edge of the first nail-free resilient floor module with the left edge of the first channel nail-free resilient floor module. This allows the right side slots 111 of the first nail-free resilient floor module to align with the left side sliders 12 of the first channel nail-free resilient floor module. Each slider 12 on the right side aligns with the slot 111 on the left side of the first nailless resilient floor module; then, the first nailless resilient floor module is laid flat, and a pushing force is applied to the right during the laying process, so that each slot 111 and each slider 12 completes the fitting connection after being laid flat, thereby completing the connection and fixation between the first nailless resilient floor module of the second path and the first nailless resilient floor module; following the installation method of the first module of the second path, the third module is installed at the rear end of the first nailless resilient floor module, and the fourth module is installed at the rear end of the third module, until the second path is installed;

[0017] S3. Install the third nail-free resilient floor module on the right side of the first nail-free resilient floor module; take a nail-free resilient floor module and tilt it so that it is higher on the right and lower on the left. The third and fourth clips 11 on the right side clamp the clips 11 at the front and rear ends of the first nail-free resilient floor module, which are aligned side by side. The left edge of the first nail-free resilient floor module is aligned with the right edge of the first nail-free resilient floor module, so that the left side slots 111 of the first nail-free resilient floor module align with the right side sliders 12 of the first nail-free resilient floor module. Each slider 12 on the left side aligns with the slot 111 on the right side of the first nailless resilient floor module; then, the first nailless resilient floor module is laid flat, and a pushing force is applied to the left during the laying process, so that each slot 111 and each slider 12 completes the fitting connection after being laid flat, thereby completing the connection and fixation of the first nailless resilient floor module with the first nailless resilient floor module; following the installation method of the first module of the third path, the third module is installed at the rear end of the first nailless resilient floor module, and the fourth module is installed at the rear end of the third module, until the third path is installed;

[0018] S4. Following the installation method of the second row of nail-free resilient floor modules, install the second row of nail-free resilient floor modules on the left side of the field one by one; following the installation method of the third row of nail-free resilient floor modules, install the third row of nail-free resilient floor modules on the right side of the field one by one.

[0019] S5. After the entire site is installed, install the dual-purpose fastener 3 along the edges of the four sides of the flooring area; drill through holes in the fastener and the nail-free resilient floor modules covered by the fastener, and connect and fix the dual-purpose fastener 3 and the nail-free resilient floor modules with screws to fix the adjacent nail-free resilient floor modules.

[0020] This application is to be dismantled using the following methods:

[0021] S01. Remove the dual-purpose fasteners 3 from the four edges of the floor area and the upper surface of the nailless elastic floor modules, so that the nailless elastic floor modules located at the four edges of the floor area are in a detachable state.

[0022] S02. On the left edge of the flooring area, lift the left edge of any nailless resilient flooring module and position it with the left side higher than the right side. This will allow the slots 111 and sliders 12 that are connected to the nailless resilient flooring module on the right side to disengage, thus removing the nailless resilient flooring module. Repeat this process to remove the nailless resilient flooring modules one by one from left to right.

[0023] S03. On the right edge of the flooring area, lift the right edge of any nailless resilient flooring module and position it with the right side higher than the left side. This will allow the slots 111 and sliders 12 that are connected to the nailless resilient flooring module on the left side to disengage, thus removing the nailless resilient flooring module. Repeat this process to remove the nailless resilient flooring modules one by one from right to left.

[0024] S04. All nail-free resilient floor modules, after removal, are ready for reinstallation at any time.

[0025] In the installation method, S2 and S3 can be performed simultaneously to speed up the installation process; in the removal method, S02 and S03 can also be performed simultaneously to improve the removal speed.

[0026] In installation methods S1-S4, if any nail-free resilient floor modules need to be cut at the beginning and end, the nail-free resilient floor modules at the beginning and end should be cut according to actual needs.

[0027] This application tilts the subsequently laid nail-free resilient flooring modules so that their locking heads 11 extend into the side underside of the already laid nail-free resilient flooring modules. Then, through a leveling action, utilizing the module's own weight and lateral thrust, the sliding heads 12 on the side of the subsequently laid nail-free resilient flooring modules slide along the arc-shaped bottom surface of the guide arc-shaped locking groove 111 into the locking groove 111 of the adjacent modules, completing self-fitting and self-locking without the need for the use or operation of any independent connecting parts. Due to its simple structure, this application can be applied to flat ground that does not require leveling, with lower material costs, lower labor costs, and more efficient installation and removal operations.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0044] It should be noted that, in order to achieve a precise guiding slope on the bottom surface of the slider 12 and a precise arc-shaped receiving surface on the slot 111, the integral molding mold used in this application has corresponding molding cavities designed in the corresponding parts; those skilled in the art know that preparing the corresponding integral molding mold according to the product design drawing is a conventional technical means.

[0045] It is understood that the number and layout of the locking head 11, the locking slot 111, and the slider 12 are not limited to those shown in the attached drawings. For example, in another embodiment, at least two pairs or more locking units may be provided on one side of the panel 10, and the shapes of the locking head 11 and the slider 12 may also be interchanged; the core is that adjacent nail-free elastic floor modules achieve self-locking through the integrally formed, mutually matching protrusions and recesses on the body, by tilting-flattening action;

[0046] The specific implementation of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0047] like Figures 1-10As shown in the figure, an embodiment of this application provides an indoor and outdoor universal detachable nail-free sports floor, including a nail-free elastic floor module. The nail-free elastic floor module includes an integrally molded floor module 1 and an elastic pad 2. The upper end of the integrally molded floor module 1 is provided with a panel 10, and the lower end, on the back of the panel 10, is provided with four supports parallel to the front and rear edges. The bottom surface of the four supports is provided with multiple recesses, and the multiple recesses are fitted and bonded with elastic pads 2.

[0048] Obtaining a nail-free resilient floor module: A one-piece molded product is obtained by solidifying organic or inorganic materials that can be molded in one piece through a special one-piece molding mold; after solidification, the one-piece molded product is removed from the mold, thus obtaining a single one-piece molded floor module 1 without the elastic pad 2;

[0049] The elastic pad 2 is bonded to the recess of the support base using adhesive to obtain a single nail-free elastic floor module.

[0050] The nail-free resilient floor modules are placed on the painting production line and painted or have an anti-slip and wear-resistant layer applied according to customer requirements.

[0051] Repeat the above steps to obtain multiple nail-free resilient floor modules.

[0052] The advantages of using the plasticity of malleable materials for one-piece molding production are: good repeatability, simple operation, product quality is not affected by the operator and external conditions; short product molding cycle, one-time molding of complex structures, accurate product dimensions, smooth and easy surface treatment, better product stability, and better bending and compressive strength.

[0053] like Figures 1-10 As shown, during installation, the long side of either the left or right side of the nailless resilient floor module is aligned with the previous nailless resilient floor module. Then, it is tilted at a certain angle so that the third and fourth clips 11 clamp the two clips 11 that are parallel at the front and rear ends of the adjacent nailless resilient floor modules in the previous path. Then, it is laid flat, and a pushing force is applied in the direction of the nailless resilient floor module in the previous path during the flattening process. After flattening, the assembly is completed. During disassembly, the long side of any nailless resilient floor module that is not connected to other nailless resilient floor modules is lifted. After reaching a certain angle, the resilient floor module can be removed to restore it to a state where it can be reassembled at any time.

[0054] like Figures 1-4 , Figure 5 , Figure 6As shown, the bottom surface of the clip 11 is a sloping surface with a lower inner surface and a higher outer surface. When the second and third nail-free resilient floor modules are assembled with the first nail-free resilient floor module, the second and third nail-free resilient floor modules need to be tilted at a certain angle so that the end of the clip 11 extends into the lower edge of the panel 10 of the first nail-free resilient floor module. The sloping bottom surface of the clip 11 increases the space between the lower edge of the front end and the base surface, so that when the nail-free resilient floor module is assembled in a tilted state, the lower edge of the front end of the clip 11 does not touch the base surface, and does not hinder the assembly of the nail-free resilient floor module or the fitting connection between the slide head 12 and the slot 111, thus ensuring the smooth and fast assembly of this application.

[0055] like Figures 1-6 As shown, the slot 111 matches the slider 12; the inner end of the slot 111 is flush with the left and right sides of the panel 10, and the bottom surface is arc-shaped. The inner end of the slot 111 transitions to the bottom surface with a slope that is higher on the inside and lower on the outside; the outer end of the slider 12 is flush with the edge of the panel 10, and the bottom surface is arc-shaped. The outer end of the slider 12 transitions to the arc-shaped bottom surface with a slope that is higher on the outside and lower on the inside. The slope transition shortens the length of the arc-shaped bottom surface and reduces the height of the outer end of the slider 12; when assembling the nailless resilient floor module, firstly, the end of the slot 11 is inserted under the panel 10 of the previous nailless resilient floor module, and then the nailless resilient floor module is laid flat. At the same time, during the flattening process, the slider 12 and the slot 111 are aligned. 111 is used for interlocking connection; during the flattening process, if the slider 12 does not have a beveled transition setting, the edge formed by the natural intersection of its outer end face and the curved bottom surface will, under the constraint of the lower corner of the side of the adjacent panel 10 against the clip 11, come into contact with the curved bottom surface of the slot 111, and cannot complete the interlocking connection with the slot 111, thus causing the nail-free resilient floor module to not be flattened and unable to complete the assembly connection; the beveled transition setting can ensure that during the interlocking connection between the slider 12 and the slot 111, the shortened curved bottom surface of the slider 12 can smoothly interlock along the curved bottom surface of the slot 111, and complete the interlocking connection with the slot 111, thereby ensuring the smooth assembly connection between the nail-free resilient floor modules;

[0056] Furthermore, the bottom surfaces of the card head 11 and the card slot 111 are designed as matching curved surfaces, which are guiding curved surfaces that facilitate smooth engagement of the card head 11 and the card slot 111 during the assembly of the nail-free resilient floor module. After engagement, the contact area between the card head 11 and the card slot 111 is maximized, which helps to give full play to the limiting and positioning function of the card head 11 and the card slot 111 on the assembled nail-free resilient floor module.

[0057] like Figures 5-8As shown, after assembly, six protruding clips 11, six slots 111 on the clips 11, and six sliding heads 12 on the lower edge of the panel 10, symmetrically arranged on the left and right sides of the panel 10, form a two-sided interconnection, two-sided mutual support, two-sided mutual limiting and positioning, and two-sided mutual locking between adjacent nail-free resilient floor modules after assembly, thereby enhancing the overall connection strength after large-area installation. The structure is simple, which facilitates the rapid assembly of nail-free resilient floor modules, simplifies the installation process, reduces the technical content of installation, and enables simple and rapid installation on flat ground that does not require leveling.

[0058] like Figure 7 As shown, the spacing between the third and fourth clips 11 is twice the width of a single clip 11 in the front-to-back direction; between the third and fourth clips 11, there are third and fourth sliders 12; when the second-path nailless resilient floor module is assembled with the first-path nailless resilient floor module, the slots 111 of the two parallel clips 11 at the front and rear ends of the first-path nailless resilient floor module align with and fit the clips 11 between the third and fourth sliders 12 of the second-path nailless resilient floor module; the slots 111 of the two parallel clips 11 at the front and rear ends of the second-path nailless resilient floor module align with and fit the clips 11 between the third and fourth sliders 12 of the first-path nailless resilient floor module.

[0059] Furthermore, the third and fourth clamping heads 11 of the second-path nailless resilient floor module clamp the front and rear two parallel clamping heads 11 of the first-path nailless resilient floor module in the front-back direction; the third and fourth clamping heads 11 of the first-path nailless resilient floor module clamp the front and rear two parallel clamping heads 11 of the second-path nailless resilient floor module in the front-back direction.

[0060] Furthermore, with the multiple sliding heads 12 and multiple slots 111 providing front-to-back positioning for adjacent nail-free resilient floor modules, the adjacent nail-free resilient floor modules clamp each other to the parallel slots 11, improving the mutual positioning capability between adjacent nail-free resilient floor modules after large-area installation. This allows the application, when used for sports activities, to maintain a long-term stable connection and integrity between the resilient modules under the violent impact of athletes' gravity and jumping.

[0061] Furthermore, the staggered joints of adjacent floor modules on the left and right sides improve the stability, integrity, and durability of the large-area paving of this application;

[0062] like Figures 6-9As shown, after assembly, the clips 11 of the adjacent nailless resilient floor modules are all located below the adjacent nailless resilient floor module panels 10 and abut against the back of the panels 10, forming mutual connection, support and mutual restriction at the joints of the adjacent nailless resilient floor modules, thereby enhancing the stability and connection firmness of this application under the impact of intense sports competitions.

[0063] Furthermore, when athletes walk, run, jump, and step on the edge seams of the adjacent nail-free elastic floor modules in the front and back directions, as well as on the upper surfaces of the panels 10 on both sides of the edge seams, their feet generate downward gravity and impact forces at the edge seams of the adjacent panels 10. The edge seams and the areas on both sides of the edge seams produce the same instantaneous deformation and vibration frequency, as well as the same physical and mechanical properties such as elasticity, shock absorption, cushioning, and rebound. This ensures that in the large venues of this application, athletes can perform their competitive skills normally during sports competitions and fitness activities.

[0064] Furthermore, after assembly, the sliding heads 12 and slots 111 of adjacent nailless resilient floor modules on the left and right sides also complete the interlocking, creating a two-way interconnection and limiting constraint, preventing the adjacent nailless resilient floor modules from losing their interconnection and becoming detached. At this time, the slot 11 must lower its height or the sliding head 12 must raise its height to allow the sliding head 12 to disengage from the slot 111 and lose its connection limiting function. If the slot 11 on either side of the adjacent nailless resilient floor modules lowers its height or the sliding head 12 raises its height, the nailless resilient floor module on the same side must lower or raise its height. However, due to the interlocking and limiting constraint of the slot 11 of the adjacent nailless resilient floor modules on the left and right sides, the nailless resilient floor module on either side remains at the same height under the limiting constraint of the slot 11, and cannot produce any different height changes. Thus, the sliding head 12 cannot disengage from the slot 111 and lose its mutual limiting constraint and interconnection.

[0065] Furthermore, in sports, oblique impacts from both sides of the joint between adjacent nail-free resilient floor modules in the left and right directions will cause the adjacent nail-free resilient floor modules to be pushed by a force in the left and right directions. The bottom surfaces of both the slider 12 and the slot 111 are curved surfaces. Under the oblique impact force, the left slider 12 slides to the left along the curved bottom surface of the right slot 111, and the right slider 12 slides to the right along the curved bottom surface of the left slot 111. At this time, regardless of whether the slider 12 moves to the right or left on the curved bottom surface of the slot 111, the height of the slider 12 needs to be increased, i.e., the height of the nail-free resilient floor module on its side needs to be increased. However, the adjacent nail-free resilient floor modules... Under the mutual connection and limiting effect of the module clips 11, the nailless elastic floor modules on either side cannot produce any different height changes. Consequently, under the violent impact force in any direction, the slider 12 cannot change its fitting state with the slot 111 by sliding along the arc-shaped bottom surface of the slot 111, thus affecting the mutual limiting and connection function. Secondly, after the large-area installation is completed, the elastic pad 2, due to the weight of the nailless elastic floor modules themselves, generates frictional resistance between itself and the base surface, further limiting and eliminating the slider 12 from changing its fitting state with the slot 111 by sliding along the arc-shaped bottom surface of the slot 111 under any oblique violent impact force, thus affecting the mutual limiting and connection function.

[0066] Furthermore, in sports activities, if the joints of adjacent nailless resilient floor modules are subjected to vertical violent impacts, the left nailless resilient floor module may tilt to the left and the right, and the right nailless resilient floor module may tilt to the right and the left, causing the left nailless resilient floor module's slot 111 to lose its engagement with the right nailless resilient floor module's slide head 12, and the right nailless resilient floor module's slot 111 to lose its engagement with the left nailless resilient floor module's slide head 12. This results in the failure and loosening of the left-right connection limit between the adjacent nailless resilient floor modules.

[0067] After large-area installation, the nail-free resilient floor modules are laid in a crisscross pattern, mutually limiting and positioning each other, transforming from individual units into a whole. When the joints of adjacent nail-free resilient floor modules are subjected to vertical violent impact, the engagement connection between the slide head 12 and the slot 111 will fail unless the left-side nail-free resilient floor module and all its front, rear, and right-side directly or indirectly connected nail-free resilient floor modules tilt together. The same applies to the right-side nail-free resilient floor module. Therefore, under any impact force, adjacent nail-free resilient floor modules will not experience any failure in their mutual engagement connection or mutual limiting and positioning.

[0068] like Figure 9 , Figure 10As shown, the dual-purpose fastener 3 connects and fixes adjacent nail-free resilient floor modules located at the edge of the flooring area; this prevents adjacent nail-free resilient floor modules from shifting or deviating, ensuring a tight joint at all times. This avoids the lack of stable connection at the edge of the nail-free resilient floor modules, which, under the repeated impact and vibration generated during sports activities, would exhibit different vibration and elasticity responses compared to the nail-free resilient floor modules inside the edge, affecting the athletes' technical performance; and it also prevents warping and tilting under the impact and vibration generated during sports activities, thus avoiding the failure of the interlocking connection and loosening of the nail-free resilient floor modules inside the edge.

[0069] Compared to existing technologies, this application, through the rational arrangement of the locking head 11, locking slot 111, and sliding head 12 integrated with the integrated nailless floor module body, does not rely on any connecting parts independent of the integrated floor module 1, such as bolts, connecting forks, fasteners, etc., for connection and fixation. It only requires a simple assembly operation of tilting and aligning individual nailless elastic floor modules, flattening them, and applying pushing force while flattening them to complete the assembly of individual nailless elastic floor modules. This achieves mutual locking, connection, limitation, and fixation of adjacent nailless elastic floor modules in the front-back, left-right, and up-down directions, forming a complete and flat surface required for sports activities. The integrated, firmly connected large flat surface; compared with the prior art, the structure of this application is simpler, and the cost of the integrated molding mold used to produce the integrated floor module 1 is lower; since there are no connecting parts independent of the integrated floor module, such as bolts, screws, connecting forks, fasteners, etc., the installation process reduces at least four steps: distribution of connecting parts, alignment, preliminary fixing, and final tightening, which significantly reduces the need for technical training of installation personnel; therefore, this application can be applied to flat indoor and outdoor ground that does not require leveling with lower production costs, lower material costs, lower labor costs, and more efficient and faster installation and dismantling operations.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
